AGENDA REPORT CITY OF MOORPARK TO: Honorable City Council ?/a.4(4) CrrYOP WORPARxCALEFORNI► city caw Meeting BY: FROM: Nelson Miller, Director of Community Developmen,, -.,. Deborah S. Traffenstedt, Principal Planner --D5-F DATE: December 9, 1997 (CC Meeting of 12/10/97) SUBJECT: CONSIDER HIDDEN CREEK RANCH SPECIFIC PLAN PROJECT (SPECIFIC PLAN NO. 8 /SPECIFIC PLAN N0. SP -93 -1, GENERAL PLAN AMENDMENT NO. GPA -93 -1, AND ZONE CHANGE NO. ZC- 93 -3), APPLICANT: HIDDEN CREEK RANCH PARTNERS (PUBLIC HEARING CligfiED ON DECEMBER 3, 1997) The December 10 City Council meeting will be the sixth Council meeting held to discuss the proposed Hidden Creek Ranch Specific Plan Project. The Council closed the public hearing on December 3, 1997. An EIR Volume VI has been distributed under separate cover to the Council, as discussed in this report. Volume VI of the EIR, in combination with staff reports and the public hearing minutes, is intended to serve as the substantial evidence in the administrative record to support a conclusion that recirculation of the Hidden Creek Ranch Specific Plan EIR is not required pursuant to Section 15088.5 of the State California Environmental Quality Act (CEQA) Guidelines. The staff recommendation is that the Council provide direction to staff if additional supplemental information is required to assist the Council in reaching a conclusion regarding certification of the EIR; and direct staff to prepare a draft resolution for EIR certification for City Council consideration at the January 7, 1998 meeting, and continue the meeting to January 7, 1998. The first five City Council public hearings for the Hidden Creek Ranch Specific Plan Project were held on October 1, 8, and 22, November 12, and December 3, 1997. At the December 3 meeting, there was City Council consensus to close the public hearing and continue the meeting to December 10 for continued City Council deliberations. The City Council intends to begin its deliberations on Environmental - Impact Report (EIR) certification at the December 10 meeting. DST c: \1- m \sp- 8\cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 3 alternative project, or deny the project is a separate decision from the certification of the Environmental Impact Report. One topic, as an example, is the impact on the Campus Park Drive /Collins Drive intersection. The Environmental Impact Report identifies the impacts of the proposed project, a variety of mitigation measures, and a number of alternatives to reduce the impacts, which included other connections to the highway network, including other connections to the freeway. However, one alternative not fully explored in the material is a connection to the future planned Alamos Canyon interchange in Simi Valley. If City Council were to determine that the project should. be approved with a requirement for the future construction of a connection to the future Alamos Canyon interchange, then additional information would probably be required prior to that decision. City Council should review the Environmental Impact Report and the concerns expressed during the City Council Public Hearings and determine if there is any additional information which should be provided in order to identify and address the impacts of the proposed project and feasible alternatives and mitigation measures which would reduce impacts to less than significant. A decision regarding the project and additional mitigation measures to be imposed to further reduce the impacts, if approved, is a subsequent decision. However, the conclusion of the EIR is that significant and cumulative impacts will remain. This fulfills the purpose of the California Environmental Quality Act (CEQA) to provide information regarding the impacts of the project to the decision makers and the public and therefore the Environmental Impact Report should be certified as in compliance with the requirements of the California Environmental Quality Act. Page 5 -1 of Volume V of the EIR for the Hidden Creek Ranch Specific Plan Project identifies the unavoidable adverse impacts of the Project should it be implemented. The following is a summary of those potentially significant impacts that were identified in Volume V of the EIR as resulting even with the implementation of feasible mitigation measures: • Biology - Loss of wildlife habitat and the feasibility for implementing coast live oak and venturan coastal sage scrub mitigation. • Land Use - Loss of prime farmlands (118 acres). • Aesthetics - Loss of visual resource of the undeveloped site; development in a scenic viewshed; unmitigateable project- impacts DST c: \1- m \sp- 8 \cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 4 from two viewpoints and unmitigateable cumulative impacts from five viewpoints; ambient increases in light and glare (including adverse effect on nighttime operations at the Moorpark College Observatory). • Traffic - Potentially significant impacts should the City not implement a Capital Improvement Plan for the Year 2010 Circulation System (General Plan buildout), or if traffic impact fees are not paid by the developer to the County for impacts to the County's road system. • Air Quality - Local Carbon Monoxide (CO) impacts; project contribution to cumulative air quality degradation. • Water Service - Potentially significant.impacts to water supplies and facility phasing should growth occur at a greater rate than projected. • Solid Waste Disposal - Contribution to cumulative loss of disposal capacity. The Council was provided with supplemental air quality impact analysis (Attachment 2 to the staff report for the December 3, 1997 meeting), which clarified that there will be no exceedance of any state or federal CO standard as a result of the Project, based on current approved emission factors, revised percentage of cold starts to hot starts from new CO protocols issued in 1996 from Caltrans, and analysis of lane configuration to match the 2010 configuration shown in the EIR. The proposed Project will not result in CO "hotspot" impacts; however, the Project will contribute to cumulative air quality degradation. Various concerns regarding potential environmental impacts were raised during the public hearings, including concerns regarding biological habitat and species, wildlife corridors, agricultural land, loss of open space, hillside grading, lighting and glare impacts on the Moorpark College Observatory, traffic, air quality, Valley Fever, long -term water availability, schools, noise, and oil well contamination. These concerns were addressed in the Draft EIR, and staff reports and supplemental studies were provided to the Council to further verify the conclusions in the EIR and respond to the various environmental concerns. Following is a brief summary of the environmental issues raised during the public hearing process: DST c: \1- m \9p- 8 \cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 5 1. Biological Resources • Wildlife Habitat and Species - Concerns were expressed regarding the significant impacts that would result to biological resources, including loss of wildlife habitat and impacts to raptors. The EIR identifies the loss of wildlife habitat and the feasibility for implementing coast live oak and venturan coastal sage scrub mitigation as significant even with the implementation of feasible mitigation measures. Loss of any active raptor nest is also identified as a significant impact; however, measures are proposed to mitigate impacts to a level that is considered less than significant. • Wildlife Corridors - Because of existing development south of the Specific Plan site, north to south movement within the site does not provide a crucial link to other significant natural areas. East to west wildlife movement in the shrub - covered hills in the northern portion of the Specific Plan site is important to wildlife movement in the region and will not be interrupted with proposed Specific Plan development. Project implementation, therefore, is expected to have.an effect on local, not regional, wildlife movement within the Specific Plan site. This impact is considered adverse but not significant. 2. Land Use • Agricultural Land - The EIR concludes that the loss of prime agricultural land is an unavoidable adverse impact of the Project. The Ventura County Agricultural Policy Advisory Committee met on December 4, 1997, and concluded that although the Committee regrets the loss of agricultural land, if the. Project goes forward, the agricultural properties should be included. The Committee's recommendation was based on numerous factors, including but not limited to the high cost of imported water, winds and chill conditions, quality of soils, topography, and location of the farmland in proximity to existing and proposed development (reference memorandum attached to this report). 3. Aesthetics • Loss of Open Space - Concerns were expressed regarding loss of open space through development of the site. The potential impacts associated with loss of open space are biological impacts due to loss of wildlife habitat and aesthetic impacts due to the potential visual change that may result. The loss DST c: \1- m \sp- 8 \cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 6 of wildlife habitat and the loss of visual resource of the undeveloped site are identified in the EIR as unavoidable adverse impacts of the Project even with the implementation of feasible mitigation measures. • Hillside grading - Concerns were expressed regarding grading of 20 percent and greater slopes and consistency with the City's Hillside Management Ordinance. The EIR concludes that the project is consistent with the stated objectives of the Hillside Management Ordinance, because it includes the retention of more than 2,500 acres of the site as natural open space and would provide remedial measures to reduce erosion and geologic hazards, limit the alteration of visible ridgelines (horizon lines) from the valley floor, preserve natural drainages, develop the densest portion of the site in the flatter portions of the site, and require use of native vegetation for replanting and other water - conserving techniques. • Light and Glare - Concerns were expressed regarding the potential significant light and glare impacts of the Project on the Moorpark College Observatory. Ambient incremental increases in light and glare, when considered on a cumulative basis and in relation to the Moorpark College Observatory, were identified in the Draft EIR as significant even with the implementation of mitigation. Additional mitigation measures were suggested by persons affiliated with the Observatory, including the Ventura County Astronomical Society, that would further control light and glare impacts. The applicant verbally agreed to additional light and glare impact reduction mitigation measures at the Council's November 12, 1997, public hearing and the revised list of mitigation measures that is currently under preparation will incorporate those additional light and glare control related measures. Actual relocation of the Observatory has not been requested by the Moorpark College President. 4. Traf f is • Campus Park Drive and Collins Drive - Residents in the Campus Park area near Moorpark College expressed concern regarding impacts on Campus Park Drive and Collins Drive and the intersection of these two roadways. Supplemental traffic count information was provided to the City Council as well as a supplemental intersection design exhibit. The Project is forecasted to add 8,000 daily trips to the Campus Park Drive /Collins Drive intersection. The supplemental traffic DST c: \1- m \sp- 8 \cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 7 information supported the original conclusion in the Draft EIR that an adequate level of service could be maintained for the Campus Park Drive /Collins Drive intersection, even without the provision of a new State Route 118 Lagoon interchange. The Project will add capacity to the Campus Park Drive /Collins Drive intersection in the form of a new free northbound right - turn lane and a second westbound left -turn lane and potential reconfiguration of other lanes. Furthermore, most of the traffic increases will be opposite existing peak flows, thereby utilizing existing unused capacity. The EIR also identifies alternatives and their impacts, including a new Lagoon interchange, alternative connections to the north end of Collins Drive, a connection to the west end of Campus Park Drive, a roadway across lower Happy Camp Canyon Regional Park (with several alternative alignments), and a roadway across Happy Camp Canyon Regional Park to connect to Broadway. These alternatives, and the impacts of making, or not making, various connections are identified in the EIR. Therefore, the EIR has fulfilled the requirements of the California Environmental Quality Act (CEQA) and should be certified. In considering the proposed project, City Council can choose among the alternatives the Council deems appropriate. The EIR identifies the impacts of the proposed project, as well as existing impacts, and the cumulative impacts of the project, and other projects and uses. Much public testimony has been received about impacts from traffic from Campus Canyon Elementary School, from existing recently completed projects, and from the continued growth of Moorpark College. The EIR includes mitigation measures to mitigate the impacts of the Project, which can also reduce cumulative traffic impacts. 5. Air Quality • Air Quality - Concerns were expressed regarding the project's contribution to cumulative air quality degradation, local Carbon Monoxide impacts, construction dust related impacts, and Valley Fever. The Project EIR identifies that cumulative air quality degradation will be significant even with the implementation of feasible mitigation measures. Further supplemental analysis of the potential for local Carbon Monoxide impacts identified that there will be no exceedance of any state or federal CO standard as a result of the Project. The EIR includes all Ventura County Air Pollution DST c: \1- m \sp- 8 \cc- 9p8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 8 Control District recommended mitigation measures for dust suppression. These same measures will also minimize potential Valley Fever impacts by minimizing the potential for fungal spores to become airborne. 6. Water Service • Long -Term Water Availability - A letter and public hearing comments were received expressing concerns regarding long -term water availability for the Project. Calleguas Municipal Water District provided a response letter which concludes that given the implementation of various programs identified in its master plan and water management measures on State, regional, and local levels, Calleguas expects to reliably meet all service area demands through its master planning horizon of 2020. 7. Schools • School Sites - After circulation of the Draft EIR, the land use plan was revised to include two elementary school sites and a high school site, in response to comments received during the public review of the Draft EIR. Supplemental information was subsequently presented to the Council by the Moorpark Unified School District and the applicant regarding other potential high school site location options, such as a location adjacent to Moorpark College, that should be discussed by the Council. Any changed location of the high school site within the Specific Plan No. 8 area would not be expected to result in a new significant impact, if such site were to be located within the area already under consideration for development. • School Fees - The applicant's school fee proposal offer to the Moorpark Unified School District is based on the District's request for a 50:50 cost split and would result in approximately $5.7 million more than the amount that is estimated to be generated using the standard $1.84 per square foot school fee method for 3,221 dwelling units. In a letter dated November 26, 1997, from the Moorpark Unified School District Superintendent (reference Volume VI), the District Superintendent identifies general concurrence with the applicant's current school fee proposal. 8. Noise • Construction Noise - The EIR identifies construction noise as sometimes adverse, due to the temporary nature of construction DST c: \1- m \sp- 8 \cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 9 activities; however, such noise would be at a level that is considered less than significant. Construction noise mitigation measures are proposed. • Traffic Noise - The EIR concludes that along roadway segments that would have higher projected traffic noise levels for the General Plan buildout scenario, less than 3 dBA increases would result, with the exception of along Spring Road within the Specific Plan No. 2 area. A 3 dBA increase is considered a just - noticeable difference and is not considered significant. Future planned residential units within Specific Plan No. 2 can be designed so as to avoid noise impacts. 9. Hazardous Materials • Oil Well Contamination - The Geotechnical and Phase I Environmental Site Assessment Report prepared by Leighton and Associates for the Draft EIR is included as Appendix B in Volume II of the EIR. Environmental constraints are addressed in that report beginning on page 41, and the conclusion is that localized staining of soils with crude oil can be mitigated. Mitigation for contamination applies to proposed development areas, including the proposed trail network in designated open space areas. Mitigation measures are included in the EIR that would protect human health and the environment, including a requirement for legal offsite disposal of any contaminated soil located within the development areas of the Specific Plan site. With implementation of the mitigation measures, impacts assodiated with hazardous materials would be reduced to a level considered less than significant. An EIR Volume VI has been distributed under separate cover to the Council. Volume VI consists of the various supplemental environmental analysis information that has been prepared in response to Project revisions that were made to minimize or avoid adverse environmental impacts, as well as to address issues raised during the five public hearings for the Project. Volume VI of the EIR, in combination with staff reports and the public hearing minutes, is intended to serve as the substantial evidence in the administrative record to support a conclusion that recirculation of the Hidden Creek Ranch Specific Plan EIR is not required pursuant to Section 15088.5 of the State California Environmental Quality Act (CEQA) Guidelines. A revised summary list of mitigation measures is also under preparation that will incorporate DST c: \1- m \ap- 8 \cc- sp8rpt.6 Hidden Creek Ranch Specific Plan To: Honorable City Council December 9, 1997 Page 10 mitigation recommendations that are addressed in Volume VI and prior staff reports. The summary list of mitigation measures will be provided to the Council prior to the next tentatively scheduled meeting on January 7, 1998. The City Council should review the documentation in Volume VI and the staff reports, and then provide direction to staff if additional supplemental information is required to assist the Council in reaching a conclusion regarding certification of the SIR. Volume VI, in combination with the prior staff reports and public testimony, supports the following conclusions: • No new significant environmental impact has been identified. • No substantial increase in the severity of an environmental impact has been identified. • No new significant impacts would result from the additional mitigation measures proposed. • The applicant has agreed to all mitigation measures identified in the SIR and in supplemental studies and staff reports. • No new feasible project alternative, considerably different from others previously analyzed, has been identified, that would clearly lessen the environmental impacts of the project. • The draft SIR was not so inadequate or conclusory that meaningful public review and comment were precluded. 1. Provide direction to staff if additional supplemental information is required to assist the Council in reaching a conclusion regarding certification of the SIR. 2. Direct staff to prepare a draft resolution for SIR certification for City Council consideration at the January 7, 1998 meeting, and continue the meeting to January 7, 1998.

COWCUNITY DEVELOPMENT DEPARTMENT MEMORANDUM T0: Nelson Miller, Director of Commmity Development FROM: Deborah S. Traffenstedt, Principal Planner �:DjT DATE: December 5, 1997 SUBJECT: COUNTY AGRICULTURAL POLICY ADVISORY COMMITTEE MEETING ON DECEMBER 4, 1997, AND RECOMMENDATION' PERTAINING TO HIDDEN CREEK RANCH SPECIFIC PLAN (SPECIFIC PLAN NO. 8) I attended a meeting of the County Agricultural Policy Advisory Committee, yesterday, in Santa Paula. As you are aware, we had received verbal notice on December 2 that consideration of the Hidden Creek Ranch Specific Plan area had been included on the Committee's agenda for a recommendation pertaining to the agricultural land within the Specific Plan area (including 118 acres of prime agricultural land) . The Agricultural Policy Advisory Committee is composed of five farming representatives (i.e., farmers). Also in attendance at the meeting were Jeff Gordon representing Messenger Investment Company and Richard Devericks representing Ventura Pacific Capital Company. The Committee directed County staff to forward a recommendation to the County Board of Supervisors that was generally to be written as follows: The Committee regrets the loss of agricultural land, but if the project goes forward, these properties should be included. The Committee's recommendation was based on the high cost of imported water, winds and chill conditions, quality of soils, topography, and location of the farmland in proximity to existing and proposed development. cc: Honorable City Council Steve Kueny, City Manager CITY OF MOORPARK MEMORANDUM TO: Honorable City Council FROM: Nelson Miller, Director of Community Developme-'.� DATE: December 5,1997 SUBJECT: HIDDEN CREEK RANCH SPECIFIC PLAN (SPECIFIC PLAN NO. 8) FINAL ENVIRONMENTAL IMPACT REPORT SUPPLEMENTAL INFORMATION (VOLUME VI) Attached is additional information to respond to environmental issues raised during review of the Environmental Impact Report as well as to document modifications to the project in response to issues to further reduce environmental impacts and to respond to modifications recommended during the review process. City Council has previously received draft copies or summaries of most of this information. Section 1 is an overall project summary, including a description of the modifications to the project in response to comments and issues raised during the review process. Staff is preparing a report for the December 10, 1997, meeting identifying issues upon which City Council may wish to focus some discussion. This will be delivered to Council prior to the meeting. Also to follow are some additional recommended mitigation measures to support the supplemental information. The purpose of an Environmental Impact Report is to identify for the decision makers and the public significant environmental effects of a proposed project, identify alternatives or mitigation measures, which the agency finds are feasible, by which such effects can be reduced or avoided. If the City does act to approve a project for which significant environmental effects are involved, which are not mitigated, the City would need to include a statement of overriding considrations which outweigh the adverse environmental impacts. Staff would recommend that the significant environmental effects of the project have been identified, alternatives and mitigation measures which are feasible have been identified, and therefore the Environmental Impact Report can be certified. Prior to any decision to approve the project the City would also need to adopt a statement of overriding considerations, however this can follow certification of the Environmental Impact Report. cc: Steve Kueny, City Manager VOLUME VI FINAL ENVIRONMENTAL IMPACT REPORT SUPPLEMENTAL STUDY INFORMATION HIDDEN CREEK RANCH SPECIFIC PLAN (NO. 8) SCH.

This information supplements information provided to the City Council in staff reports during the public hearing process to respond to environmental issues raised by the public, agencies, and the City Council upon their review of the EIR, as well as document modifications to the project in response to issues raised by the public, agencies, and city staff to further reduce significant environmental effects associated with project implementation, and finally, to respond to directives of the Planning Commission. The following information is provided in Volume VI: • Hidden Creek Ranch Project Summary • Traffic Information • Planning Unit 45 Supplemental Study Report • Updated Spring Road Study • Geotechnical Information • Air Quality Information • Water Service Information • School Provision Information • List of Mitigation Measures In accordance with the standards set forth in the California Environmental Quality Act (CEQA) Guidelines, Section 15088.5, which addresses recirculation of Environmental Impact Reports (EIRs) prior to certification, recirculation of the draft EIR for the Hidden Creek Specific Plan project is not required because: • No new significant impacts would result from the additional mitigation measures proposed. • No substantial increase in severity of an impact is anticipated that has been previously addressed without an increase in mitigation. • The applicant has not declined to adopt the mitigation measures. • The draft EIR was not so "inadequate or conclusory" that meaningful comment was precluded. CEQA Guidelines do not require a lead agency to consider recirculation of an EIR because new mitigation or proposed project improvements are included based on responses to comments submitted on a draft EIR, the Planning Commission's recommendations on the project, or are otherwise added to improve the project/reduce significant environmental effects.

Project modifications have been made to: 1) respond to environmental issues raised by the public and agencies upon their review of the EIR; 2) respond to requests from city staff to continue to pursue ways to decrease environmental effects associated with the project; 3) integrate Planning Commission recommendations; and 4) include modifications requested by the project applicant and agreed to by city staff. Modifications made to the project subsequent to the circulation of the draft EIR would not result in any new significant environmental impacts, increase the severity of identified significant impacts, result in any mitigation measures or alternatives that the project applicant has declined to adopt, or result in the identification of deficiencies in the draft EIR. Rather, changes and modifications that have been made prior and subsequent to the circulation of the draft EIR have been to reduce /avoid significant environmental effects. Recirculation of a draft EIR prior to certification is only required under very limited circumstances. CEQA Guidelines, Section 15088.5, addresses recirculation of Environmental Impact Reports (EIRs) prior to certification. The section reads as follows: "(a) A lead agency is required to recirculate an EIR when significant new information is added to the EIR after public notice is given of the availability of the draft EIR for public review under Section 15087 but before certification. As used in this section, the term 'information' can include changes in the project or environmental setting as well as additional data or other information. New information added to an EIR is not'significant unless the EIR is changed in a way that deprives the public of a meaningful opportunity to comment upon a substantial adverse environmental effect of a project or a feasible way to mitigate or avoid such an effect (including a feasible project alternative) that the project's proponents have declined to implement. 'Significant new information' requiring recirculation include, for example, a disclosure showing that: (1) A new significant environmental impact would result from the project or from a new mitigation proposed to be implemented. (2) A substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance. (3) A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the project, but the project's proponents decline to adopt it. MoorparkJ001 1 Project Summary Hidden Creek Ranch Speck Plan (4) The draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. (Mountain Lion Coalition v. Fish & Game Com. (1989) 214 Cal.App.3d 1043). (b) Recirculation is not required where the new information added to the EIR merely clarifies or amplifies or makes insignificant modifications in an adequate EIR. (c) If the revision is limited to a few chapters or portions of the EIR, the lead agency need only recirculate the chapters or portions that have been modified. (d) Recirculation of an EIR requires notice pursuant to Section 15087, and consultation pursuant to Section 15086. (e) A decision not to recirculate an EIR must be supported by substantial evidence in the administrative record." CEQA Guidelines do not require a lead agency to consider recirculation of an EIR because new mitigation or proposed project improvements are included based on responses to comments submitted on a draft EIR, the Planning Commission's recommendations on the project, or are otherwise added to improve the project. Recirculation of the draft EIR for the Hidden Creek Specific Plan project is not required because: • No new significant impacts would result from the additional mitigation measures proposed. • No substantial increase in severity of an impact is anticipated that has been previously addressed without an increase in mitigation. • The applicant has not declined to adopt the mitigation measures. • The draft EIR was not so "inadequate or conclusory" that meaningful comment was precluded. MoorparkJ001 2 Project Summary Hidden Creek Ranch Specific Plan REQUESTED DISCRETIONARY ACTIONS A. CERTIFICATION OF A FINAL ENVIRONMENTAL IMPACT REPORT The project requires the acceptance of an environmental document prepared in compliance with CEQA, the state CEQA Guidelines, and the City of Moorpark CEQA Procedures, and certification that the data was considered in the final decisions on the project. General Plan Amendment (GPA -93 -1) A General Plan Amendment (GPA) is required to reflect the final approved specific plan land use designations, circulation system, and environmental setting information on the Moorpark General Plan exhibits. Specific Plan No. 8 (SP -93 -1) The City of Moorpark's General Plan requires the use of specific plans to systematically implement General Plan policies and priorities and identifies that the intent of a specific plan is to achieve a long -term cohesive development program which is responsive to the physical and economic opportunities and constraints of the specific plan area. Prezone (ZC -93 -3) The project requires a change of zone. This would be adopted as a prezone prior to the annexation of the site from the County of Ventura into the City of Moorpark. Subsequent Actions Subsequent actions on the project will include but are not limited to the following: • Consideration by the Ventura Local Agency Formation Commission (LAFCO) of a Sphere of Influence amendment and annexation. City of Moorpark The City of Moorpark, as lead agency, can approve subsequent actions without additional environmental documentation, unless as otherwise required by Public Resources Code Section 21166, state CEQA Guidelines Section 15160 et seq. The following is a list of subsequent actions that are anticipated to be required by the city to allow for project implementation: MoorparkJ001 3 Project Summary Hidden Creek Ranch Specific Plan • Development Agreement • Adoption of an ordinance amending Title 17 of the Moorpark Municipal Code to address new zone districts and standards • Master tentative tract map • Other tentative and final tract maps and parcel maps • Conditional use permits • Residential and commercial planned development permits • Grading permits • Haul route approval • Building permits • Acquisition of easements and right -of -way and construction of roads and accessways • Mello -Roos Community Facilities Act District Formation • Community Facilities District Formation • Tree removal permit • Encroachment permits • Miscellaneous permits B.

The General Plan notes that the number. of dwelling units shall not exceed 2,400 unless the specific plan area property owners agree to provide public improvements, public services, and /or financial contributions that the City Courcil determines to be of substantial public benefit to the community, in which event, the number of dwelling units shall not exceed 3,221. General Plan: Proposed City of Moorpark The amount and locations of land to be designated Residential, Open Space, etc. will be determined at the time of specific plan deliberation by the City Council. Land Use Element: Amend Land Use Element Exhibit No. 3 and Table 3 to reflect the Specific Plan land uses. Circulation Element: Amend Circulation Element Exhibit No. 2 (Highway Network), No. 3 (Bikeway Element), and No. 4 (Equestrian Trail Network) to reflect Specific Plan vehicular and non - vehicular circulation plans. Zoning: Existing County of Ventura Agricultural Exclusive (A -E) City of Moorpark None established MoorparkJ001 4 Project Summary Hidden Creek Ranch Speck Plan Zoning: Proposed City of Moorpark Amend the city zoning map by ordinance to prezone the Specific Plan site consistent with the proposed land uses. Amend the City Municipal Code, Title 17, Zoning, by ordinance to establish controlling development regulations for the site. MoorparkJO01 5 Project Summary Hidden Creek Ranch Specific Plan ENVIRONMENTAL IMPACT REPORT (EIR) PROJECT HISTORICAL BACKGROUND A. PROJECT MODIFICATIONS PRIOR TO COMPLETION OF DRAFT EIR Drainage After discussions with the County of Ventura Flood Control District, the project's flood control plan was altered incorporating a detention basin to retain water onsite and minimize.the downstream peak flows from the site. Biological Resources Upon completion of biological surveys, the primary arterial through the Specific Plan site - Hidden Creek Drive -was relocated to avoid significant habitat areas. Development Boundaries During the environmental analysis process, there were several boundary adjustments between development areas (planning units) and areas proposed for permanent open space dedication to minimize /reduce significant environmental impacts, especially to biological resources. Aesthetics /Grading Upon completion of line -of -site exhibits, the grading plan was revised to minimize /reduce the visibility of the project's cut slopes from offsite land uses. Archaeological Resources Due to the number of archaeological sites found on the easternmost portion of the Specific Plan area (noted as Planning Unit 45), the planned residential units were removed (approximately 215 dwelling units) by the applicant. For the draft EIR analysis, the designation was changed to Private Open Space; no grading or development was assumed. The draft EIR notes that °a second golf course may be proposed in the future for the eastern portion of the site; it is not a part of this project and will require subsequent environmental review and discretionary action approvals." Transportation Improvements After completion of the traffic analysis and other environmental surveys used in preparation of the draft EIR, it was determined that the Lagoon interchange with State Route 118 (SR -118) was not MoorparkJO01 6 Project Summary Hidden Creek Ranch Specific Plan required for as a part of the project because it does not provide substantial traffic benefits and because other less costly circulation /mitigation options were identified. Therefore, the traffic analysis in the draft EIR did not assume the Lagoon interchange as a project design feature. Implementation of the Lagoon interchange and roadway connection with the Specific Plan site would have significant environmental impacts including the loss of ±114 oak trees associated with the grading of the alignment through steep terrain. B. PROJECT AS SET FORTH IN THE DRAFT EIR Project Land Uses As Set Forth in the Draft EIR The project, as addressed in the draft EIR, is as follows in Table 1 and Exhibit 1. Project Phasing As Set Forth in the Draft EIR Buildout of the Specific Plan site was proposed to occur over 11 or more years. The overall phasing plan for the project is depicted in Table 2 and Exhibit 2. While market conditions was assumed to ultimately dictate phasing, prior to the occupancy of any dwelling units, infrastructure improvements would be required to accommodate the onsite development. Primary improvements for the initial phases of the project, as identified in the draft EIR, are identified below. The estimated construction period for these infrastructure improvements was 1-1/2 to 2 years. • Extension of Campus Park Drive into the Specific Plan site. • Partial construction of Hidden Creek Drive from the existing easterly terminus of Campus Park Drive west to Broadway. The full right -of -way would be graded; two lanes would be paved. • Construction of the easterly storm water detention site adjacent to the community commercial center, and site drainage improvements (i.e., debris basins as required by project drainage studies. • Provision of offsite sewer and water extensions to the Specific Plan site. • Construction of one Zone B water reservoir.

MoorparkJ001 12 Project Summary Hidden Creek Ranch Specific Plan C. PROJECT MODIFICATIONS SUBSEQUENT TO PUBLIC REVIEW OF THE DRAFT EIR: MITIGATION MEASURES IMPLEMENTED BY THE PROJECT APPLICANT In response to public and agency comments received on the draft EIR regarding the environmental effects associated with implementation of the Hidden Creek Ranch Speck Plan (SP No. 8), the City of Moorpark requested the project applicant to consider additional modifications. The purpose of the modifications were to: 1) lessen the environmental effects associated with the project and 2) increase the public benefit of the project to justify the requested increase in residential dwelling units from 2,400 to 3,221. The maximum number of units allowed for the Specific Plan site under the city's General Plan is 3, 22. The applicant presented several modifications /mitigations for consideration. Several of these modifications/mitigations were recommended by the City of Moorpark Planning Commission to the Moorpark City Council for incorporation into the project. The project applicant's recommended revised land use plan is included as Table 3 and Exhibit 3. The revised grading plan is included as Exhibits 4A and 4B. Planning Units 1, 19, and 36 The draft EIR analyzed these planning units as residential development sites at a density category of rural -low- density (0 - 0.5 du /ac). These planning units are in the northernmost portion of the development area, at the highest elevations proposed for development. The project applicant indicted his willingness to remove one or a combination of these three planning units from the Speck Plan by redistributing the allowable dwelling units (up to 70 units) to other planning units. Eliminating development from these planning units would retain an additional 279 acres in natural open space, but would also eliminate this housing typelrural density from the Specific Plan. The Planning Commission's recommendations to the City Council was to retain Planning Units 1, 19, and 36 as originally proposed in the Specific Plan. Subsequent to the Planning Commission's actions on the project, the project applicant proposed a reduction in acreage of these planning units to lessen environmental impacts associated with development in these areas of the site. Planning Unit 1 decreased in acreage from 139.1 acres to 43.8 acres with a reduction of dwelling units from 35 to 15. Planning Unit 19 decreased in acreage from 94.5 acres to 61.3 acres. Planning Unit 36 decreased in acreage from 45.3 acres to 25.5 acres. The applicant had proposed an average density of 1 dwelling unit per two acres or less for these three planning areas combined with no mass grading except to provide an access road to the area. Based on the revisions to these three planning units, Planning Unit 1 MoorparkJ001 13 Project Summary Hidden Creek Ranch Specific Plan would still be in the density range for Rural- High- Density Residential (0 - 0.5 du /ac); the other two planning areas would exceed the density for this zoning designation. Based on the evaluation of the biological habitat values of Planning Units 1, 19A, 19B, and 36, staffs recommendation is that the residential units shown within Planning Unit 19B be relocated to another planning unit(s). This revision to the land use plan would result in the preservation of an additional 22.3 acres of natural open space. Planning Unit 19B contains both chaparral and Venturan coastal sage scrub habitats. Planning Units 1, 19A, and 36 contain non - native grassland, and based on the existing topography and existing access rights for oil drilling operations, have little value for wildlife movement purposes. The applicant has verbally agreed to staffs recommendation for Planning Unit 19B to provide as an additional biological mitigation and impact avoidance measure. Planning Units 4 and 41 The project applicant offered to the Planning Commission that 33 acres of the 42.3 -acre Planning Unit 4 could be used as a natural open space park. The Planning Commission's recommendation to the City Council was to include this additional park or open space area in the Specific Plan project for the following reasons: • Fewer acres of grading • Increased parkland /open space within the Specific Plan site • Retention of biological resources including approximately 618 oak trees • Reductions in grading result in less short-term (grading - related) air emissions To incorporate this use, the applicant has modified the land use plan such that Hidden Creek Drive would be relocated to the west (rather than the east) side of the commercial center and very- high - density residential planning units (originally depicted as Planning Units 37, 7, and 8; revised land use plan are depicted as Planning Units 7, 8, and 9). This open space use would occur in an area of Planning Unit 4 originally proposed for medium - density - residential development. This portion of the specific plan site has been modified such that Planning Unit 4 contains 120 medium - density residences on 32.4 acres; Planning Unit 41 (previously part of Planning Unit 4) is 67 acres of natural open space "oak woodlands open space." Oak Trees The number of oak trees affected by project implementation is directly related to the number of trees displaced through grading and construction activities and indirectly impacted through potential impropertinadequate long -term maintenance.

MoorparkJ001 17 Project Summary Hidden Creek Ranch Specific Plan scenario with an assumption of no oak trees preservedfavoided because of mass grading of all developed planning units. However, it is feasible and anticipated that many oak trees could be preserved within a planning unit by avoidance. At this stage in the planning process, the applicant is requesting the approval of a Specific Plan. Subsequent approvals for the site will be required as more definitive development plans within individual planning units are submitted for city consideration. Detailed information regarding lot placement, etc., required for a tentative map, is not required for a Specific Plan; therefore, worst -case assumptions were made in the draft EIR. It is feasible and anticipated for oak trees to be avoided through the following methods: • As more detailed planning is conducted for the Specific Plan project. • New Planning Unit 41 (previously a part of Planning Unit 4), is located east of the Community Center commercial center, and is proposed to be a natural open space area instead of residential development. Approximately 618 oak trees that would have been removed to allow for the construction of residences will be retained. • Should the Lagoon interchange and access road not be constructed, approximately 114 oak trees would be retained. Although oak trees may be impacted should the Almos Interchange and access road (or another interchange and access road) be constructed, it is not believed that the same density of trees occur in these alternative locations. The Planning Commission's resolution included a recommendation to the City Council that a second easterly access be constructed by project year 10, if additional traffic analysis determines that this access is needed, subject to CEQA evaluation. Project Phasing The draft EIR identified the project's phasing plan as commencing in the first year with the development of Planning Units 15, 16, 18, and 31, which are noncontiguous planning units and generally located in the central portion of the project. The project applicant recommended to the Planning Commission modifications to the phasing plan such that development would generally proceed from east to west. Development is proposed to occur in four phase areas (A through D) as depicted in Exhibit 5. These phases indicated the general sequence for the development of major land use areas. It should be noted that all development within a phase would not necessarily be constructed before development of the next phase commences. Several factors including the arterial road system, public services, and economic/marketing conditions could affect the buildout schedule and sequence of development. The project a:: olicant has anticipated that buildout of the project would be completed in approximately 15 years. For each development phase, a Master Tract Map for the area within the phase is proposed to be recorded. These Master Tract Maps would create parcels sized for sale to builders which correspond to the individual planning units or portions thereof so that tract maps and related MoorparkJOO1 18 Project Summary Hidden Creek Ranch Speck Plan land use permits can be processed for individual development projects. In addition to the Master Tract Maps, there will be grading and infrastructure plans. It is intended by the project applicant to submit these grading and infrastructure plans concurrent with the Master Tract Maps as grading and commencement of the backbone infrastructure is expected to impact areas outside of the Master Tract boundaries. A new mitigation measure could be adopted to require that individual development projects could proceed as long as necessary public service infrastructure and services are available, as documented in grading and infrastructure plans submitted with any master tentative map application. For each development phase, a Master Tract Map for the area within each phase should be required. In the first development phase (Area A), residential Planning Units 2 through 9 would be constructed. Buildout of residences within the planning units would be subject to market conditions but is expected to take at least five years. The applicant has indicated that this schedule assumes that necessary infrastructure (roads, water, sewer, utilities, an elementary school, and an improved park [Planning Unit 42A]) will be in place as specked by the expected conditions of approval for the proposed project, development agreement, and master tentative map. Commencement of Area B will require the improvement of Hidden Creek Drive to either a point on the east side of Specific Plan No. 2 ( "C" Street through Happy Camp Canyon Regional Park), or to another road connection that meets the approval of the Fire District. The effects of modifying the phasing plan are as follows: • Less mass grading would occur at the start of project implementation. For example, the original phasing plan would result in approximately 133 acres of grading within the planning units in year 1, plus grading for Hidden Creek Drive from Campus Park Drive (east) extending westerly to Happy Camp Canyon Regional Park by year 1 -1/2. • Less grading can minimize the potential for erosion and lessen short-term (grading- and construction- related) air emissions. • Eliminate the need for a western roadway extension through Happy Camp Canyon Regional Park early in the site's development. The "C" Street connection to Spring Road through lower Happy Camp Canyon Regional Park is proposed by the applicant to occur when Specific Plan No. 2 has built the internal road system between Spring Road and the east side of its site adjacent to the park. Until then, Hidden Creek Ranch would use an interim connection to Campus Park Drive or other suitable connection providing fire, circulation, and public safety requirements. Transportation Improvements /Phasing As a part of the modified project, the following roadways will be provided. It is noted below in parentheses as to whether these roadway improvements are changes from the original proposal in the draft EIR. MoorparkJ001 19 Project Summary Hidden Creek Ranch Specific Plan An extension of Campus Park Drive (east) into the Specific Plan site would be constructed in year 1. (No change) Hidden Creek Drive as an east -west arterial through the site would serve as the primary roadway through the project site. The roadway would be accessed from the extension of Campus Park Drive (east) into the project site where it would become Hidden Creek Drive on the eastern side of the Specific Plan site. Hidden Creek Drive would transverse the site east to west with access from the west via a roadway connecting to an extension of Spring Road ( "C° Street) through Happy Camp Canyon Regional Park. Hidden Creek Drive would be constructed in phases as development is implemented east to west through the Specific Plan site. (Change) • The Specific Plan originally showed the Broadway Road connection through Happy Camp Canyon Regional Park. The "C" Street connection is proposed to pass through the park and would occur south of the originally proposed Broadway connection. Hidden Creek Drive through the Specific Plan site has been relocated adjacent to Planning Units 37A, 37B, and 39C to allow for the Spring Road connection. (Change) • The "C" Street connection through Happy Camp Canyon Regional Park would be constructed through the park extending into the Specific Plan No. 2 site immediately west and into the Specific Plan No. 8 site (becoming Hidden Creek Drive). The roadway would be constructed as a two -lane Village Collector. (Change) • Residential collector road from Collins Drive /Campus Road would run east to the commercial center in Planning Unit 38A. This road is intended to serve as a secondary access into the site until determined by the City that a permanent secondary access is required. Project - related traffic would increase on Collins Drive and Campus Road associated with vehicles using this residential collector road. (Change) • As previously discussed, the traffic analysis determined that the Lagoon interchange with SR -118 (a secondary easterly access) was not needed subject to other traffic improvements. However, the Planning Commission recommended that a second easterly access point to the site via SR -118 be constructed by the 10th year, if the City Council determines the need for an additional connection to SR -118, based upon additional traffic analysis. It is expected that this second site access would be provided by either the construction of the Lagoon interchange or the Alamos interchange with an associated access road into the Specific Plan site. Consideration of an interchange at Lagoon would be subject to environmental review. (Change) Planning Unit 45 The following summarizes modifications that have occurred to Planning Unit 45. Please refer to the Planning Unit 45 Supplemental Study Report for additional information regarding the proposed zoning for this planning unit. The land use plan, as depicted in the draft EIR, identified Planning Unit 45 as a 690 -acre natural open space area with no active land uses proposed as a part of the project. The draft EIR does disclose the applicant's desire to develop a golf course in Planning Unit 45 in the future, subject to additional environmental documentation. The zoning was previously proposed to permit various open space uses for Planning Unit 45. Planning Unit 45 is now shown as only 450 acres, and the project applicant is requesting the city's MoorparkJ001 20 Project Summary Hidden Creek Ranch Speck Plan consideration of modifications to the site plan to zone 450 acres of the Specific Plan site (Planning Unit 45) for Open Space /Golf Course (OS /GC); no golf course development would be entitled as a part of the currently proposed Hidden Creek Ranch Specific Plan project. The applicant has indicated that approximately 175 to 200 of the 450 acres is anticipated to be needed for a future golf course; the remainder (250 to 275 acres) would be retained in natural open space. The remaining 240 acres that were originally a part of Planning Unit 45 would be a part of the dedicated permanent open space area of the Specific Plan site. City staff previously indicated to the project applicant that if all required environmental studies are completed for Planning Unit 45, prior to City Council action on the Specific Plan, if no new significant adverse environmental effects are identified, and if the northerly 240 acres of the original Planning Unit 45 are designated as natural open space, staff could recommend a zoning designation for the southerly portion of Planning Unit 45 that would permit a golf course. The project applicant, at the direction of city staff, has prepared and submitted to the city a detailed tree survey and archaeological assessment of Planning Unit 45 to support the prezone of the planning unit to OS /GC. Additional environmental assessment has been completed to address the revised land use, which is considered environmentally preferable to the original Private Open Space designation. New mitigation measures have been identified to ensure mitigation /avoidance of potential environmental effects that may occur with a future golf course and open space in Planning Unit 45. These measures will be incorporated into the final EIR and Mitigation Monitoring Program. Transportation Improvements: Lagoon Interchange Modifications to the project's circulation system with respect to the Lagoon interchange are discussed above. Transportation Improvements: Western Roadway Connection Through Happy Camp Canyon Regional Park As a part of the project, and consistent with the Moorpark General Plan Circulation Element assumptions, the project applicant proposed the extension of "C" Street through Happy Camp Canyon Regional Park connecting to Hidden Creek Drive through the Specific Plan site. The traffic analysis prepared for the draft EIR indicates that a small percentage of the vehicular trips expected from the proposed project were expected to use Broadway, and would provide limited benefit to the city with respect to subregional circulation improvements. At the same time, the entitlement process for the Specific Plan No. 2 project, located west of the Specific Plan No. 8 site and the regional park, commenced. The Specific Plan No. 2 site plan depicted a roadway connection through its site which would facilitate a vehicular access through lower Happy Camp Canyon Regional Park via Spring Road. Traffic projections suggested that a Spring Road MoorparkJ001 21 Project Summary Hidden Creek Ranch Specific Plan connection to serve both specific plan sites would provide better traffic distribution than the Broadway connection. A Spring Road Study was prepared for Planning Commission evaluation to determine if a Spring Road connection would result in any new significant environmental effects that would not occur with the Broadway Road extension or that could not be mitigated to a level that is considered less than significant. The Spring Road study noted that a connection would not result any new significant impacts that could not be mitigated. The Planning Commission recommended approval of the Hidden Creek Specific Plan project to the City Council with the Spring Road connection. The Planning Commission indicated that the alignment of this roadway should be moved further north of the existing residences on Hastings, Lafayette, and East Cambridge streets. Subsequent to Planning Commission actions, the Spring Road Study was revised to address an alignment approximately 800 feet north of the nearest residence (an increase in distance of approximately 600 feet to the north). At the west end of the revised alignment (at Specific Plan No. 2), the roadway would be approximately 1,000 feet north of the southwest comer of Happy Camp Canyon Regional Park. The point of connection at Speck Plan No. 8 to the east remains the same. Transportation Improvements: Hidden Creek Drive East The project applicant has realigned and shifted Hidden Creek Drive through the site to the west (in the eastern portion of the specific plan site). This realignment will preserve additional oak trees (approximately 100 trees) identified in the draft EIR as being displaced associated with the roadway. The realigned road will also provide access to Planning Unit 38A, a commercial center in the southeastern portion of the site, from the east and west. Utilities: Sewer Treatment Options for the provision of sewer treatment for the Specific Plan land uses are addressed in the draft EIR. These options are an onsite sewer treatment facility and use of the county's facilities. Waterworks District No. 1 believes the benefits of tying into the existing sewer treatment plant outweigh those of providing a treatment plant on the project site. Schools The project as addressed in the draft EIR identified three elementary school sites in Planning Units 39A, 398, and 39C. Each site was proposed to be 1F :res. The Moorpark Unified School District subsequently updated their student generation — rs and capacity projections, MoorparkJO01 22 Project Summary Hidden Creek Ranch Specific Plan and determined that three elementary schools would not best meet the district's projected needs. Based on the district's student generation factors, the Specific Plan project is expected to generate the need (at full buildout of 3,221 units) for two elementary schools, 71 percent of a middle school, and 31 percent of a high school. It should be noted that projected new students is a conservative factor because 10 percent of the 3,221 units would be developed as senior housing. The School District has now requested that two elementary school sites and one high school site be identified within the Specific Plan site. Therefore, a 12 -acre elementary school site is shown in Planning Unit 39A, a 12 -acre elementary school site is shown in Planning Unit 39B, and a 43 -acre high school site is shown in Planning Unit 39C. A middle school site has been identified within proposed Specific Plan No. 2, west of Happy Camp Canyon Regional Park (source: Specific Plan No. 2 site plan dated September 9, 1997). Other Modifications In the central portion of the site, Planning Unit 18 is shifted north of Hidden Creek Drive to facilitate better access into this planning unit. The golf course, originally identified as Planning Units 40 and 41, has been consolidated into one planning unit, Planning Unit 40. Planning units on the west side of the Specific Plan site, not owned or controlled by the project applicant, have been reconfigured such that each parcel under separate ownership has its own planning unit. The reconfigured planning units include Planning Units 27 through 35. Each of these planning units has a zoning density of 0.5 dwelling units per acre or greater. The equestrian center has been relocated to Planning Unit 43, a location considered by the applicant to be more accessible to Happy Camp Canyon Regional Park and open space areas. The amount of acreage for commercial /retail uses has been decreased from 29.2 acres to 21.5 acres. This would reduce the expected square footage by approximately 84,000 square feet.

The responses are numbered according to the draft October 13, 1997 Agenda Report that was prepared by The City. QUESTION 2 - COLLINS /CAMPUS PARK INTERSECTION AFA prepared a "Before - After" evaluation of the re- phasing of the traffic signal at Collins and Campus Park Drives which revealed that a substantial improvement in the traffic flow had been achieved. When this information was presented to the City Council, a question arose since the "After" traffic volumes appeared to have dropped, whereas the school population was increasing. This apparent inconsistency is addressed here. Secondly, the City Council raised a question of how LOS "C" would be maintained at this same intersection after Hidden Creek Ranch added so much traffic. This issue is also examined. Issue 1 - Before -After Analysis Hourly traffic for the "Before" condition (January 1997), compared to the "After" condition (August - September 1997) are illustrated in Figures 1 and 2. Figure 1 is traffic northbound on Collins Drive (south of Campus Park Drive), while Figure 2 shows traffic exiting Moorpark College. This comparison shows that the current traffic volume is practically unchanged. However, the "problem" with the peak hour comparison is that the peak hour occurs at different times. On Mondays and Wednesdays the peak hour begins at 7:00 AM, whereas on Tuesdays and Thursdays the peak hour begins at 8:00 AM. Unfortunately the peak hour data used in the "Before - After" report compares the same "hour" in the After as the Before condition. This, in fact, does result in a shifting of the peak hour which distorts a "true comparison of the peak traffic condition. To remove the effect of this shifting of peak hours on different days a second evaluation has been prepared. This analysis compares the peak 30 minutes before with. the peak 30 minutes after Hidden Creek Ranch Specific Plan 1 Austin -Foust Associates, Inc. Responses to Transportation and Circulation Issues 380016.tn period, regardless of the actual start time of those periods. A 30 minute period was chosen since the peak traffic really occurs during a half hour period and use of a one hour period also distorts the comparison in favor of the "after" condition. These results continue to show a marked improvement on LOS (0.92 to 0.70) while the peak volumes remain essentially unchanged. BEFORE/AFTER LOS COMPARISON' (Peak 30 minute period) INTERSECTION Before After Collins at Campus Park AM PM AM PM 0.92 0.50 0.70 0.42 Issue 2 - How Can the Intersection of Collins and Campus Park Drive Remain LOS "C" After the Project is Built? The project will add both a significant increase in traffic and capacity to the existing intersection. Figures 3.6-13 and 3.6-14 in the EIR show year 2010 peak hour volumes without Hidden Creek Ranch while Figures 3.6-17 and 3.6-18 show the same, with traffic from Hidden Ranch. Comparison of these figures show Hidden Creek Ranch adds considerable traffic to the intersection but in a direction that is in the reverse of the existing flow. In other words, in the morning while traffic flows into Moorpark College, it flows out of Hidden Creek Ranch. For example, during the AM peak hour approximately two- thirds of the Hidden Creek Ranch traffic flows outbound while external traffic flows into Moorpark College. This allows Hidden Creek Ranch to take advantage of existing but unused intersection capacity in the outbound direction in the morning peak period. A similar situation occurs in the afternoon but to a lesser degree, when 60 percent of project traffic flows back in while Moorpark College is exiting. However, taking advantage of surplus of --ctional capacity is not the main reason an LOS "C" will be maintained. The project will add cap,-, Ay in the form of a new "free" northbound right - turn lane and a second westbound left -turn lane. The "free" northbound lane will accommodate the Hidden Cheek Ranch Specific Plan 2 Austin -Foust Associates, Inc. Responses to Transportation and Circulation Issues 380016.tn heavy inbound flow (i.e., destined for Moorpark College in the AM and Hidden Creek Ranch in the PM) while the added capacity afforded by a second left -turn lane will accommodate the outbound flow. In a sense, Hidden Creek Ranch is providing an additional inbound and outbound lane at the Collins- Campus Park Drive intersection to accommodate its traffic. QUESTION 3 - COLLEGE ENROLLMENT Moorpark College indicates they expect only an increase of 470 students (2.3 percent) through year 1999. The traffic model, calibrated for 1994, assumed an increase of 2,660 students from year 1994 to year 2000. This is a 26.6 percent increase. The traffic model assumes even more aggressive growth, up to 17,000 trips by year 2010 (i.e., a 70 percent increase over the 1994 base year). A comparison of the traffic model's assumed growth, with Moorpark College's projections, indicates the traffic model is very conservative. For example, the traffic model's assumed growth up to year 2000 is significantly greater than Moorpark College's actual projections. This is not meant to cast suspicion on the model, but merely to report the conservative nature of the growth assumptions regarding Moorpark College enrollment. Moorpark College affects the Collins- Campus Park Drive intersection in precisely the reverse order of Hidden Creek Ranch. That is, when Moorpark College students arise Hidden Creek Ranch residents are leaving and vice versa. These "compatible" traffic patterns take maximum advantage of available roadway capacity. QUESTION 5 - SPRING/HIGH INTERSECTION IMPACTS In 1996 a supplemental traffic analysis was conducted by Associated Transportation Engineers (ATE) to examine the impacts associated with the potential extension of Spring Road through Happy Camp Regional Park. The results, which were summarized in a technical report that was presented to the Moorpark Planning Commission in August 1996, indicate that acceptable levels of service would be maintained at the intersection of High Street and Spring Road in both the near -term (year 2000) and long -range (year 2015) if a Spring Road extension were to access the Hidden Creek Ranch development. Hidden Creek Ranch Specific Plan 3 Austin -Foust Associates, Inc. Responses to Transportation and Circulation Issues 380016.tn QUESTION 8 - PROJECT TRIP GENERATION Upon buildout of the project a total of about 47,000 daily trips can be expected to be generated. This general statement, while true, severely overstates any increase in trips particularly on the surrounding circulation system, particularly the freeway system. Over 16,000 of the 47,000 trips are commercial retail trips generated by the neighborhood shopping center(s). These types of trips generally do not use the freeway. For example, how many times do you get on a freeway to go to the grocery store? Similarly, retail trips involve what is known in the traffic industry as "double counting." A trip is defined as either an origin or destination. Therefore, a single shopping trip originating anywhere within the specific plan area and ending at the shopping center is counted as two trips. Yes, that is right, two trips! One trip is the origin, at home, the other is the destination, at the shopping center. However, these two trips did not leave the specific plan area. Therefore, simply using the project's overall trip generation to forecast increased traffic on the freeways results in a gross exaggeration. The City's traffic model does deal with this issue of double counting and trips that remain within the specific plan area that do not impact the regional transportation system. With that explanation of overall trip generation and caution in interpretation of these figures, it is accurate to report that the project anticipates generating roughly 42 percent of its total traffic (i.e., 20,000 ADT out of a total buildout of 47,000 ADT) by year 2000 and the traffic study has been prepared with such a phasing plan in mind. QUESTION 9 - SIGNALIZATION Generally speaking, an arterial street such as Hidden Creek Ranch Road, can be anticipated to function satisfactorily with a four -way stop (or all -way stop) control up to a volume of 10,000 ADT. When the traffic exceeds about 10,000 then delays during peak hours will start to become noticeable and the minimum warrants indicating the need for signals will be exceeded at the higher volume side street intersections. The minimum warrant for signals occurs when the volume exceeds 8,000 to 9,000 Hidden Creek Ranch Specific Plan 4 Austin -Foust Associates, Inc. Responses to Transportation and Circulation Issues 380016.tn ADT on Hidden Creek Ranch Drive but actual need, as evidenced by delay, etc. generally occurs when volumes exceed 10,000 ADT. QUESTION 10 - REGIONAL IMPACTS The traffic study utilized the Moorpark Traffic Model which anticipated that implementation of regional transportation improvements would be tied closely to their need. For example, Route 23 improvements (i.e., widening to six lanes) are included in the model, but will this improvement really occur? About all that can be stated at this point is that Route 23 is a regionally identified CMP deficiency whose widening is being actively pursued for inclusion in the Ventura County's Regional Transportation Improvement Program (RTIP) by all agencies involved. Is this a guarantee? No, of course not, but nevertheless it is a strong indication that something is likely to be done, and its assumption for inclusion in the traffic model a realistic one. The traffic model basically balances development with transportation capacity and, while providing no assurance, the interrelationship and necessity of one with the other does tend to validate the reasonableness of such an assumption. Funding for State Route freeway improvements which are included in the RTIP and the Statewide Transportation Program (STIP) is generated by a combination of State and Federal fuel (gas) taxes and motor vehicle fees. Freeway system users that are generated by the Hidden Creek Ranch development will therefore contribute to freeway improvements through the payment of fuel taxes and motor vehicle fees. The EIR indicates that, based on the level of project impact, mitigation is required for the SR -118 Freeway east of Erringer Road (widening of this freeway is planned but is as yet unfunded) in order for the project to be considered consistent with the Ventura County General Plan. Although traffic mitigation fees that are collected by the County may not necessarily be specifically intended for improving the SR -23 or SR -118 Freeways, the County General Plan does allow projects such as Hidden Creek Ranch to participate in the County's Traffic Mitigation Fee Program as a way of complying with the General Plan (i.e., rather than having to provide direct mitigation, in this case for the SR -118 Freeway).

SUBJECT: COLLINS DRIVE IN FRONT OF CAMPUS CANYON ELEMENTARY SCHOOL DATE: November 20, 1997 At the October 22, 1997 City Council meeting a concern was raised regarding traffic flow on Collins Drive in front of Campus Canyon Elementary School and the fact that the traffic counts obtained for the Collins /Campus Park signal evaluation were collected when the elementary school was not in session. Austin -Foust Associates, Inc. (AFA) performed a subsequent review whereby peak traffic conditions during arrival and dismissal of Campus Canyon Elementary School was taking place. This review disclosed that peak 30 minute counts did increase during the morning arrival and mid- afternoon dismissal periods, but that this did not make a significant difference in the total daily count nor in the critical 30 minute arrival period for Moorpark College students and staff in the morning. It was noted, however, that southbound (downhill) Collins Drive is limited to a single lane and that this is a major factor in the congestion that occurs. While the reasoning behind this single lane is understandable, i.e., to discourage College traffic from using this routing and to reduce speeds in front of the elementary school, the current congestion is the unfortunate result. Frankly, if this delay or "inconvenience" did not occur, additional traffic volumes with higher speeds would likely result. The supplemental analysis did reveal that traffic flows along Collins Drive in both directions is highly peaked even within the span of one hour. The traffic flow peaks sharply with the College class start times and drops off markedly in between. This presents an opportunity to adjust the starting and ending time of the elementary school to correspond with the periodic minimum flow periods on Collins Drive. However, these peaks and valleys (see attached figure) are a function of college classes and could change each semester. Nonetheless, a slight rescheduling of class start and ending times, if practical, could have a dramatic impact on traffic flow on Collins Drive. 380016.mm2 City of Moorpark November 20, 1997 Page 2 In summary, it is concluded that the restriction of southbound Collins Drive to a single lane contributes significantly to the congestion. However, adding a second lane has other negative impacts which seemingly outweigh the relatively brief periods of congestion during school arrival and dismissal. The highly peaked nature of the peaking of traffic flow along Collins Drive does offer an opportunity for a slight shifting of school start and dismissal times to reduce congestion. However, such a move would be the responsibility of the school district. 380016.mm2 CITY OF MOORPARK REVIEW OF COLLINS /CAMPUS PARK SIGNAL OPERATION Technical Notes Prepared for: City of Moorpark Prepared by: Austin -Foust Associates, Inc. 2020 North Tustin Avenue Santa Ana, California 92705 -7827 (714) 667 -0496 February 25, 1997 CITY OF MOORPARK REVIEW OF COLLINS /CAMPUS PARK SIGNAL OPERATION Technical Notes The intersection of Collins Drive and Campus Park Drive in the City of Moorpark currently experiences delay and congestion during peak periods, particularly during the morning peak hour when students arrive for classes at Moorpark College. The existence of this congestion introduces a concern that future traffic from other sources, such as the proposed Hidden Creek Specific Plan, may worsen the situation to an intolerable level. Austin -Foust Associates, Inc. (AFA) has been retained to review the existing condition to determine what, if anything, can be done to improve the situation. ANALYSIS A vicinity map illustrating the three study intersections is presented in Figure 1. Current traffic data was collected in January 1997 at the three intersections on Collins Drive between Los Angeles Avenue and Campus Park Drive is shown in Figure 2. A capacity analysis was performed using the intersection capacity utilization (ICU) methodology, as well as through computerized simulation of traffic flow using a program known as TRANSYT -7F, a sophisticated analytical tool designed especially for this type of analysis. The data and computer model runs are included in the appendix, while the results are discussed herein. Currently the signal at the intersection of Collins Drive and Campus Park Drive is operated in a somewhat unconventional manner. That is, the northbound and southbound movements are entirely separate (i.e., northbound traffic proceeds while all other movements are stopped, then southbound movements proceed while northbound stops). At some intersections which have very high left -turn movements compared with the corresponding through movement, this type of signal phasing works well. However, at this location it is the north -south through movements (including the northbound right -turn) that are experiencing the highest volume. In order for the intersection to operate most efficiently, the northbound and southbound through movement needs to operate simultaneously rather than sequentially.

Technical Notes 380016.tn A test of this generally acknowledged traffic engineering fact was conducted using both the ICU and TRANSYT -7F traffic flow simulation. The results clearly indicated such is also the case at this location. Based solely on the lane geometry, this intersection has the capability of operating at a level of service (LOS) "C" (ICU = .80) if the north -south through movements are green at the same time. Under the current split -phase sequence (i.e., north -south through movements timed separately) the intersection is predicted to operate at LOS "E' during the morning peak period. Therefore it is concluded that the current signal phasing should be changed to a more conventional "dual left" turn operation in lieu of the current "opposite" operation (using Caltrans terminology to describe these two types of signal phasing). This simple change in the phasing will produce a dramatic improvement in the delay at this intersection. Discussion with Caltrans representative responsible for this location indicates implementation of such a change is already underway. The plan is to install a dual left operation for the left -turns on Collins Drive. This includes changing the signal to enable the north -south through movements to occur together. Review of the existing intersection traffic movements indicates another improvement is available that could further enhance the current operation. The northbound right -turn movement is quite heavy in the peak hour (up to 900 vph) while the eastbound through movement is always low but has two lanes dedicated to this nominal volume. A more efficient use of roadway space would be to create a northbound "free" right -turn lane by elimination of the number two existing eastbound through lane and using this lane as a free northbound right -turn lane. This improvement could be accomplished within the existing roadway space. However, a better option would be to create a small traffic island of the southeast comer and create a conventional free right -turn lane. A small piece of right -of -way from the adjacent park would be required to implement a conventional free right -tum lane. But it would allow a continuous movement for the heavy northbound right - turning traffic. CONCLUSION In summary, it is concluded that the existing signal phasing (called "opposite" or split phasing in technical terms) is not the most efficient operation for the current and future traffic volumes and lane geometry at the intersec-':)n of Collins Drive and C -,pus Park Drive in the City of Moorpark. Caltrans is planning a change :o implement a conventio_ "dual left" operation which will result in Review of Collins/Campus Park Signal Operation 4 Austin -Foust Associates, Inc. Technical Notes 380M16.tn a substantial improvement in the level of service -- both existing and future. A further improvement not currently planned could be achieved by creating a northbound free right -turn lane. Two options exist to do this, one of which involves acquisition of some right- of-way from the park on the southeast comer. But even without this right -of -way a free northbound right -turn lane can be created by dedicating the roadway space used by the number two eastbound lane for this purpose.

The responses are numbered according to the draft October 13, 1997 Agenda Report that was prepared by The City. QUESTION 2 - COLLINS /CAMPUS PARK INTERSECTION AFA prepared a "Before- After" evaluation of the re- phasing of the traffic signal at Collins and Campus Park Drives which revealed that a substantial improvement in the traffic flow had been achieved. When this information was presented to the City Council, a question arose since the "After" traffic volumes appeared to have dropped, whereas the school population was increasing. This apparent inconsistency is addressed here. Secondly, the City Council raised a question of how LOS "C" would be maintained at this same intersection after Hidden Creek Ranch added so much traffic. This issue is also examined. Issue 1 - Before -After Analysis Hourly traffic for the "Before" condition (January 1997), compared to the "After" condition (August - September 1997) are illustrated in Figures 1 and 2. Figure 1 is traffic northbound on Collins Drive (south of Campus Park Drive), while Figure 2 shows traffic exiting Moorpark College. This comparison shows that the current traffic volume is practically unchanged. However, the "problem" with the peak hour comparison is that the peak hour occurs at different times. On Mondays and Wednesdays the peak hour begins at 7:00 AM, whereas on Tuesdays and Thursdays the peak hour begins at 8:00 AM. Unfortunately the peak hour data used in the "Before - After" report compares the same "hour" in the After as the Before condition. This, in fact, does result in a shifting of the peak hour which distorts a true comparison of the peak traffic condition. To remove the effect of this shifting of peak hours on different days a second evaluation has been prepared. This analysis compares the peak 30 minutes before with the peak 30 minutes after Hidden Creek Ranch Specific Plan 1 Austin -Foust Associates, Inc.

In a sense, Hidden Creek Ranch is providing an additional inbound and outbound lane at the Collins- Campus Park Drive intersection to accommodate its traffic. QUESTION 3 - COLLEGE ENROLLMENT Moorpark College indicates they expect only an increase of 470 students (2.3 percent) through year 1999. The traffic model, calibrated for 1994, assumed an increase of 2,660 students from year 1994 to year 2000. This is a 26.6 percent increase. The traffic model assumes even more aggressive growth, up to 17,000 trips by year 2010 (i.e., a 70 percent increase over the 1994 base year). A comparison of the traffic model's assumed growth, with Moorpark College's projections, indicates the traffic model is very conservative. For example, the traffic model's assumed growth up to year 2000 is significantly greater than Moorpark College's actual projections. This is not meant to cast suspicion on the model, but merely to report the conservative nature of the growth assumptions regarding Moorpark College enrollment. Moorpark College affects the Collins- Campus Park Drive intersection in precisely the reverse order of Hidden Creek Ranch. That is, when Moorpark College students arise Hidden Creek Ranch residents are leaving and vice versa. These "compatible" traffic patterns take maximum advantage of available roadway capacity. QUESTION 5 - SPRING/HIGH INTERSECTION IMPACTS In 1996 a supplemental traffic analysis was conducted by Associated Transportation Engineers (ATE) to examine the impacts associated with the potential extension of Spring Road through Happy Camp Regional Park. The results, which were summarized in a technical report that was presented to the Moorpark Planning Commission in August 1996, indicate that acceptable levels of service would be maintained at the intersection of High Street and Spring Road in both the near -term (year 2000) and long -range (year 2015) if a Spring Road extension were to access the Hidden Creek Ranch development.

QUESTION 10 - REGIONAL IMPACTS The traffic study utilized the Moorpark Traffic Model which anticipated that implementation of regional transportation improvements would be tied closely to their need. For example, Route 23 improvements (i.e., widening to six lanes) are included in the model, but will this improvement really occur? About all that can be stated at this point is that Route 23 is a regionally identified CMP deficiency whose widening is being actively pursued for inclusion in the Ventura County's Regional Transportation Improvement Program (RTIP) by all agencies involved. Is this a guarantee? No, of course not, but nevertheless it is a strong indication that something is likely to be done, and its assumption for inclusion in the traffic model a realistic one. The traffic model basically balances development with transportation capacity and, while providing no assurance, the interrelationship and necessity of one with the other does tend to validate the reasonableness of such an assumption. Funding for State Route freeway improvements which are included in the RTIP and the Statewide Transportation Program (STIP) is generated by a combination of State and Federal fuel (gas) taxes and motor vehicle fees. Freeway system users that are generated by the Hidden Creek Ranch development will therefore contribute to freeway improvements through the payment of fuel taxes and motor vehicle fees. The EIR indicates that, based on the level of project impact, mitigation is required for the SR -118 Freeway east of Erringer Road (widening of this freeway is planned but is as yet unfunded) in order for the project to be considered consistent with the Ventura County General Plan. Although traffic mitigation fees that are collected by the County may not necessarily be specifically intended for improving the SR -23 or SR -118 Freeways, the County General Plan does allow projects such as Hidden Creek Ranch to participate in the County's Traffic Mitigation Fee Program as a way of complying with the General Plan (i.e., rather than having to provide direct mitigation, in this case for the SR -118 Freeway).

SUBJECT: COLLINS DRIVE IN FRONT OF CAMPUS CANYON ELEMENTARY SCHOOL DATE: November 20, 1997 At the October 22, 1997 City Council meeting a concern was raised regarding traffic flow on Collins Drive in front of Campus Canyon Elementary School and the fact that the traffic counts obtained for the Collins /Campus Park signal evaluation were collected when the elementary school was not in session. Austin -Foust Associates, Inc. (AFA) performed a subsequent review whereby peak traffic conditions during arrival and dismissal of Campus Canyon Elementary School was taking place. This review disclosed that peak 30 minute counts did increase during the morning arrival and mid- afternoon dismissal periods, but that this did not make a significant difference in the total daily count nor in the critical 30 minute arrival period for Moorpark College students and staff in the morning. It was noted, however, that southbound (downhill) Collins Drive is limited to a single lane and that this is a major factor in the congestion that occurs. While the reasoning behind this single lane is understandable, i.e., to discourage College traffic from using this routing and to reduce speeds in front of the elementary school, the current congestion is the unfortunate result. Frankly, if this delay or "inconvenience" did not occur, additional traffic volumes with higher speeds would likely result. The supplemental analysis did reveal that traffic flows along Collins Drive in both directions is highly peaked even within the span of one hour. The traffic flow peaks sharply with the College class start times and drops off markedly in between. This presents an opportunity to adjust the starting and ending time of the elementary school to correspond with the periodic minimum flow periods on Collins Drive. However, these peaks and valleys (see attached figure) are a function of college classes and could change each semester. Nonetheless, a slight rescheduling of class start and ending times, if practical, could have a dramatic impact on traffic flow on Collins Drive. 380016.mm2 IV ° � 1 i r rj r/ rJlf r I r ! � r ri r r ji' r rlir WV+.1wavo M 11� q� 9 l I s� J COLLINS N/O CAMPUS PARK 15 MINUTE TRAFFIC VOLUMES - SOUTHBOUND ,fl 500 400 300 200 Ki U 6:00 AM 7:00 8:00 9:00 10 :00 11:00 12:00 PM 1 :00 2:00 3 :00 4:00 5:00 6:00 APPENDIX 1�_ - I t W 1 Y ! \t � S m k\ \ j � c oo 3 t C \ I I \ \ 1 } \ � W I \ ; \ \ I Z �WK KK ; G i ! } \ W Z r\ W N r \ 0-'m �; .. .. . .. 4 \ \ \ \\ zoo ' �►i . 0. } o �ogW m �Aldp N W W m 10 �r a= 1�_ - I t 1 Y ! \t � S \ j � c 3 t C \ I I \ \ t I \ \ I 1�_ - 1,800 1,600 1,400 O 1,200 M W 1,000 a 800 U 600 400 200 U ' 7:00 am COLLINS S/O CAMPUS PARK - NB HOURLY VOLUME ♦ • r ,:row 0 !r✓ r • • r • r � r r y r r 3:00 pm DAY "wwww JANUARY 1997 " " " - WED AUG 97 '- '-' `- - TI-IUR AUG 97 r - r - - - FRI AUG 97 (*Af,Xh&) — — — MON AUG 97 — ' '— r TUTS AUG 97 7 :00 am COLLINS S/O CAMPUS PARK - SB HOURLY VOLUME ♦ ♦ / ,r r ♦� , r / /N. ♦ V i r . . . ` ,13EFol?E .�16X)1fL AP1001r ` - � . _ .. . 3:00 pm DAY JANUARY 1997 " " — — ' WED AUG 97 — "- — THUR AUG 97 - - - - - - FRI AUG 97 CVE.cua — _ _ MON AUG 97 -- - — TUES AUG 97 1,200 - 1,(100 - O 800 a 600 400 - 200 7 :00 am COLLINS S/O CAMPUS PARK - SB HOURLY VOLUME ♦ ♦ / ,r r ♦� , r / /N. ♦ V i r . . . ` ,13EFol?E .�16X)1fL AP1001r ` - � . _ .. . 3:00 pm DAY JANUARY 1997 " " — — ' WED AUG 97 — "- — THUR AUG 97 - - - - - - FRI AUG 97 CVE.cua — _ _ MON AUG 97 -- - — TUES AUG 97 m�� 500 !I1I1] 300 200 W 0 -1 6:00 AM COLLINS N/O CAMPUS PARK 15 MINUTE TRAFFIC VOLUMES - SOUTHBOUND 9:00 SB 8/21/97 12 :00 PM SB 8/28/97 3:00 6:00 DIX 500 400 300 200 100 COLLINS S/O CAMPUS PARK 15 MINUTE TRAFFIC VOLUMES - NORTHBOUND 9:00 12:00 PM 3:00 6:00 NB 8/20/97 NB 8/27/97 zil 500 400 md 300 200 100 0 -&- 6:00 AM COLLINS S/O CAMPUS PARK 15 MINUTE TRAFFIC VOLUMES - SOUTHBOUND 9:00 SB 8/20/97 12:00 PM SB 8/27/97 3:00 6:00 TRAFFIC DATA SERVICES, INC.

Johnston, Senior Ecologist November 20, 1997 Hidden Creek Ranch Specific Plan (No. 8) HIDDEN CREEK RANCH SPECIFIC PLAN (NO. 8) SUPPLEMENTAL STUDY REPORT FOR PLANNING UNIT 45 INTRODUCTION The Hidden Creek Ranch Specific Plan (No. 8) draft Environmental Impact Report (EIR) (September 1995) reflected the applicant's request for a zoning designation of Private Open Space (OS -2) for Planning Unit 45. The draft EIR identified that it was the applicant's intent to request clearance for development of a golf course in the future. Table 11 in the draft Hidden Creek Ranch Specific Plan (June 1995) identifies that the following are permitted uses under the OS -2 (Private Open Space) zoning designation: Permitted By Zoning Clearance: • Animal husbandry, Without structures (as stipulated in the zoning code) • Apiculture (note: the zoning code stipulates specific restrictions for this use) • Grading (as stipulated in the zoning code) • Motion picture and TV production and related activities and structures, temporary, maximum 42 days in any 180 -day period (as stipulated in the zoning code; subject to specific restrictions for this use) • Storage of building materials, temporary (as stipulated in the zoning code; subject to specific restrictions for this use) • Accessory uses and structures (other than to agriculture, animals, or dwellings) Administrative Permit: • Accessory uses to crop production: - Fuel storage - Insecticides for pest control • Parking lots • Pastures and training areas • Shade structures Planning Commission Approved Conditional Use Permit: • More animals than are permitted by Section 17.28.030C of the Moorpark Zoning Code • Barns and Stables • Cemeteries • Crop Production - Firewood operations • Communications facilities • Drilling, temporary geologic (testing only) • Festivals and similar events, temporary outdoor (less than three in one year) • Greenhouse, hothouses • Libraries • Mineral resource development: MooMar*V1Yanning Unit 45 Planning Unit 45 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) - Mining and accessory uses less than nine months in duration (note: the zoning code stipulates specific restrictions for this use) - Oil and gas exploration and production (note: the zoning code stipulates specific restrictions for this use) • Motion picture and TV production, and related activities and structures • Pipelines and transmission lines, aboveground (note: the zoning code stipulates specific restrictions for this use) • Public utility facilities, excluding offices and service yards (as stipulated in the zoning code) • Riding stables With accessory lodging facilities With outdoor arenas /accessory structures • Water production, storage, and distribution facilities: private purveyors (as stipulated in the zoning code; most public water facilities are exempt from these regulations) City Council Approved Conditional Use Permit: • Crop Production • Wholesale nursery • Greenhouse, hothouses and the like The June 1995 draft Specific Plan includes further clarification that the uses identified in Table 11 will be permitted by Zone Clearance, Administrative Permit, Planned Development, or Conditional Use Permit, provided that, in each case, the applicant can provide evidence to the Director of Community Development that there will not be a significant impact upon recorded archaeological sites, sensitive biological habitat, or mature or oak trees. The draft EIR stated that additional environmental review would be required prior to any development in Planning Unit 45 (designated as Private Open Space) because of potentially significant impacts to biological and archaeological resources. The draft EIR included mitigation measures for impacts to biological and archaeological resources associated with development of the Specific Plan No. 8 site. Since the release of the draft EIR, the applicant has formally requested that the city consider a zoning designation for Planning Unit 45 that would conditionally permit a golf course for the southern 450 acres and has agreed that the northerly 240 acres should be designated as natural open space. In the revised land use plan dated September 1997, Planning Unit 45 is now shown as a 450 -acre area with an Open Space /Golf Course (OS /GC) designation. A corresponding Open Space /Golf Course zone is also proposed that would include very restrictive requirements for a single golf course that would be designiDd to protect the more sensitive biological habitat areas as open space and limit the overall area that could be graded. In comparison, the Private Open Space Zone that was described in the June 1995 draft Specific Plan would have permitted a variety of agricultural, institutional, recreational, and open space uses that could potentially have greater environmental effects than a golf course (see previous summary of permitted uses in the OS -2 zone). MooWrkwanning Unit 45 Planning Unit 45 2 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) The following supplemental information has been prepared for Planning Unit 45: (1) a tree survey; (2)additional biological survey and vegetation mapping; (3) Phase II archaeological resources studies; and, (4) additional of review of all other CEQA- related environmental issues as they would apply to Planning Unit 45. These studies /reviews have been conducted in compliance with the requirements stated in the draft EIR to allow for future development within Planning Unit 45. The draft EIR stated there would be significant impacts associated with Specific Plan development; the impacts associated with Planning Unit 45 were not described in detail. A development plan for Planning Area 45 was not submitted as part of the Specific Plan application, and has not been subsequently submitted to the city. In coordination between the city and applicant, potential future development assumptions were made to prepare the impact analysis. The impact discussion that follows is speculative and is considered a worst -case analysis. In an effort to fully disclose the potential impacts of development which could occur as a result of Open Space /Golf Course zoning, potential development impacts are discussed based on preliminary concepts from the applicant. The assumptions used in this analysis are as follows: • Planning Unit 45 was identified in the draft EIR as a 690 -acre site. To evaluate the proposed zoning of this portion of the Specific Plan site as Open Space /Golf Course (OS /GC), the acreage of Planning Unit 45 has been changed based on the September 1997 revised land use plan. The southern 450 acres is now Planning Unit 45 and would, subject to approval by the Moorpark City Council, be zoned OS /GC, which would allow only natural open space and golf course uses. No other uses would be permitted. • The remaining 240 acres in the northern portion of the site are no longer a part of Planning Unit 45, but have been added to the dedicated permanent open space, increasing the total acres by 240 acres. • The OS /GC zoning designation would only allow a single 18 -hole golf course and related facilities with a Conditional Use Permit (CUP). • Approximately 200 acres of the 450 -acre planning unit would be impacted by golf course development. Although a "link style" golf course is envisioned, which is less intrusive and damaging to natural habitat, the 200 -acre figure was used as the analysis factor to ensure that potential effects are not underestimated. An actual links golf course would likely damage less than the 200 acres assumed in this analysis. • Of the 200 acres, approximately 80 percent (160 acres) would occur within the upland plateau portions of Planning Unit 45 and the remaining 20 percent (40 acres) would occur within the canyon areas. Mmmar* Planning Unit 45 Planning Unit 45 3 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Please note that impacts were evaluated in conjunction with those impacts for the Specific Plan and were based on the same significance criteria described in the draft EIR. BIOLOGICAL RESOURCES This portion of the study describes the results of an assessment of the existing biological resources present within Planning Unit 45 of Specific Plan No. 8. Information within this study has been compiled from previous surveys, data compilation, field verification, and refinement of plant community mapping to provide the decision makers of the City of Moorpark with the necessary information for their consideration of zoning Planning Unit 45 "OS /GC." Ann M. Johnston, Senior Ecologist, and Amy L. Leverett, Botanist, with BonTerra Consulting conducted this biological resources assessment based on information provided in the draft EIR and response to comments on the draft EIR, aerial photographs of the site, and a plant community mapping field assessment of Planning Unit 45. Plant Communities Planning Unit 45 contains approximately 450 acres of undeveloped land, including both native California and non - native plant communities. These communities occur in several small canyons and drainages that run from north to south through Planning Unit 45. As depicted on Exhibit 1, the topographic features in this planning unit provide for a variety of plant communities including Venturan coastal sage scrub (191.6 acres), chaparral (6.3 acres), coast live oak woodland (53.7 acres), southern coast live oak riparian forest (19.6 acres), non - native grassland (50.5 acres), and coastal sage scrub /non- native grassland ecotone (128.3 acres). The plant communities are summarized in Table 1. Venturan Coastal Sage Scrub Venturan coastal sage scrub occurs throughout Planning Unit 45. Dominant shrub species in this community include purple sage (Salvia leucophylla), black sage (Salvia mellifera), chaparral bushmallow (Malacothamnus fasciculatus), California buckwheat (Eriogonum fasciculatum), and California sagebrush (Artemisia califomica). Other shrub species commonly occurring include deerweed (Lotus scoparius), white sage (Salvia apiana), California bush sunflower (Encelia califomica), and coastal goldenbush (Isocoma menziesii var. menziesii). Shrub cover varies from sparse to impenetrable; however, in most stands annual and perennial herbs commonly occur. Other plants occurring in the coastal sage scrub community include coastal prickly pear (Opuntia littoralis), Santa Barbara loco weed (Astragalus trichopodus), coast paintbrush (Castilleja afnis), chia (Salvia columbariae), golden yarrow (Eriophyllum confertiflorum), MoorpafWfanning Unit 45 Planning Unit 45 4 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) California fuchsia (Epilobium canum), giant wild rye (Leymus condensatus), and lance- leaved dudleya (Dudleya lanceolata). TABLE 1 PLANT COMMUNITIES OCCURRING WITHIN PLANNING UNIT 45 AND ADDITIONAL PRESERVED OPEN SPACE Chaparral Chaparral occurs sporadically throughout Planning Unit 45, often integrated with Venturan coastal sage scrub and coast live oak woodland. The most common chaparral plant species present include big - podded ceanothus ( Ceanothus megacarpus), scrub oak (Quercus berberidifolia), chamise (Adenostoma fasciculatum), poison oak (Toxicodendron diversilobum), holly -leaf redber y (Rhamnus ilicifolia), toyon (Heteromeles arbutifolia), laurel sumac (Malosma laurina), and lemonadeberry (Rhus integrifolia). Where the shrub canopy is closed, the understory is dominated by deep leaf litter. Under sparse canopies, herbs present include yellow pincushion (Chaenactis glabriuscula), Turkish rugging (Chorizanthe staticoides), California spineflower (Mucronea californica), prickly cryptantha (Cryptantha muricata), sacapellote (Acourtia microcephala), bird's beak (Cordylanthus rigidus ssp. setigerus), and Mediterranean schismus (Schismus barbatus).

Moorpaf* Planning Unit 45 Planning Unit 45 5 Supplemental Study Report Hidden Creek Ranch Speck Plan (No. 8) Coast Live Oak Woodland Throughout the southern portion of Planning Unit 45, coast live oak woodland occurs on gentle slopes, along intermittent streams, and in protected canyons. The oak distribution onsite includes areas of oak forest (where canopies overlap), oak woodland (where canopies range from 50 to 75 percent cover), and oak savanna (where the canopies are well spaced). The dominant plant species in the coast live oak woodland is the coast live oak (Quercus agrifolia). The understory ranges from dense shrubby undergrowth (primarily Venturan coastal sage scrub species) to non - native grassland species, as discussed below. The oaks within the Specific Plan site, including Planning Unit 45, are primarily limited to mature trees with a noticeable absence of seedling and sapling age trees. This lack of age diversity around onsite tree resources is directly related to the cattle grazing pressures on the site for over 70 years. Southern Coast Live Oak Riparian Forest Southern coast live oak riparian forest occurs in the drainage located in the southern portion of Planning Unit 45. This riparian forest merges upstream with coast live oak woodland and up- slope with chaparral. The dense forest canopy is dominated by mature coast live oaks with occasional California sycamore (Plantanus racemosa), arroyo willow (Salix lasiolepis), and golden willow (Salix lucida ssp. lasiandra). The understory associated with the intermittent drainage includes Indian rush (Juncus textilis), yerba mansa (Anemopsis califomica), mulefat (Baccharis salicifolia), wild rose (Rosa californica), and poison oak. A tree survey for Planning Unit 45 was conducted in summer 1997 (Tree Survey for Planning Unit 45 of the Hidden Creek Ranch Specific Plan, October 1, 1997). A total of 4,198 trees was assessed and mapped within the planning unit. The tree inventory identified 3,892 coast live oaks, 190 western sycamores, 74 willows, 2 Fremont cottonwoods, 13 toyons, 8 Mexican elderberries, and 19 scrub oaks. These tree resources primarily occur within the coast live oak woodland and southern coast live oak riparian forest in the north -south trending canyons of the Planning Unit 45. Non - Native Grassland Non - native grassland in Planning Unit 45 is the result of historical grazing by cattle; some of these areas have also been disced and farmed in the past. Non - native grasslands are dominated by the following introduced species: wild oat (Avena fatua), slender oat (Avena barbata), soft chess (Bromus hordeaceus), foxtail chess (Bromus madritensis ssp. rubens), and ripgut grass (Bromus diandrus). Remnant stands of native grassland occur in limited isolated patches on steep slopes within the non - native grassland. Native grassland species present MooWrkV21anning Unit 45 Planning Unit 45 6 Supplemental Study Report Hidden Creek Ranch Speck Plan (No. 8) include purple needlegrass (Nassella pulchra), foothill needlegrass (Nassella lepida), western wild rye (Elymus glaucus), beardless wild rye (Leymus triticoides), June grass (Koeleria macrantha), and alkali sacaton (Sporobolus airoides). Coastal Sage Scrub /Non- Native Grassland Ecotone Coastal sage scrub /non- native grassland ecotone occurs throughout Planning Unit 45. It occurs mainly on the tops of the hills and along gentle slopes. Non - native grasslands are the dominant plant species present within this community. Species present include wild oat, slender oat, and dove weed (Eremocarpus setigerus). The coastal sage scrub plant species occur sporadically and in limited numbers throughout this vegetation community. Species present include black sage, coastal goldenbush, California sagebrush, and coastal prickly pear. The coastal sage scrub species present occur in a density of approximately 5 to 20 percent. These areas are most likely recovering from historical disturbances (cattle grazing practices). Wildlife Several amphibian species occur, or potentially occur, within the plant communities of Planning Unit 45. Frog and toad species potentially occurring in all habitat types include the western spadefoot toad (Scaphiopus hammondi), western toad (Bufo boreas), and Pacific tree frog (Hyla regilla). Oak and riparian woodlands on the site have the potential to support several salamander and newt species including the Monterey salamander (Ensatina eschscholtzi eschscholtzi), Pacific slender salamander (Batrachoseps pacificus), black - bellied salamander (Batrachoseps nigriventris), arboreal salamander (Aneides lugubris), and coast range newt (Taricha torosa torosa). The grassland, scrub, and chaparral communities onsite support numerous snakes and lizards including the side - blotched lizard (Uta stansburiana), western fence lizard (Sceloporus occidentalis), California homed lizard (Phrynosoma coronatum frontale), coastal western whiptail (Cnemidophorus tigris multiscutatus), coachwhip (Masticophis flagellum), glossy snake (Arizona elegans), gopher snake (Pituophis melanoleucus), common kingsnake (Lampropeltis getulus), western rattlesnake (Crotalus viddis), striped racer (Masticophis lateralis), coastal rosy boa (Lichanura trivirgata roseofusca), coast patch -nosed snake (Salvadora hexalepis virgultea), lyre snake (Trimorphodon biscutatus), and night snake (Hypsiglena torquata). Oak and riparian woodlands typically support a different reptile fauna than more open habitats; however, many species use both. Additional reptiles observed or expected in these communities include the western skink (Eumeces skiltonianus), silvery legless lizard (Aniella pulchra pulchra), southern alligator lizard (Gerrhonotus multicarinatus), western blind snake (Leptotyphlops humilis), and two- striped garter snake (Thamnophis hammondi). Moorpar* Planning Unit 45 Planning Unit 45 7 Supplemental Study Report Hidden Creek Ranch Speck Plan (No. 8) Bird species expected within riparian habitat on the site include warbling vireo (Vireo gilvus), northern oriole (Icterus galbula), house wren (Troglodytes aedon), and black- headed grosbeak (Pheucticus melanocephalus). Oak woodlands onsite provide nesting habitat for the scrub jay (Aphelocoma coerulescens), bushtit (Psaltriparus minimus), western bluebird (Sialia mexicana), and ash - throated flycatcher (Myiarchus cinerascens). Spring migrants to this community include western tanager (Piranga ludoviciana), hermit warbler (Dendroica occidentalis), and yellow warbler (Dendroica petechia brewsten). Chaparral and coastal sage scrub are also considered important habitat for many birds including the California thrasher (Toxostoma redivivum), wrentit (Chamaea fasciata), and greater roadrunner (Geococcyx califomianus). Summer visitors observed nesting in this habitat include Costa's hummingbird (Calypte costae) and Lazuli bunting (Passerina amoena). Winter visitors may include species such as the white - crowned sparrow (Zonotrichia leucophrys) and fox sparrow (Passerella iliaca). Bird species expected to nest in the grasslands of the site include the western meadowlark (Sturnella neglecta), grasshopper sparrow (Ammodramus savannarum), and lark sparrow (Chondestes grammacus). Raptors such as the red - tailed hawk (Buteo jamaicensis) and American kestrel (Falco sparverius) prefer grasslands and other open habitats for foraging. The varied natural communities found on the site support many species of mammals. Mammals expected within Planning Unit 45 include the pallid bat (Antrozous pallidus), brazilian free - tailed bat (Tadarida brasiliensis), western mastiff bat (Eumops perotis), California pocket mouse (Perognathus califomicus), Pacific kangaroo rat (Dipodomys agilis), California mouse (Peromyscus califomicus), brush mouse (Peromyscus boylir), California ground squirrel (Spermophilus beecheyi), Audubon's cottontail (Sylvilagus audubonii), raccoon (Procyon lotor), striped skunk (Mephitis mephitis), dusky- footed woodrat (Neotoma fuscipes), mule deer (Odocoileus hemionus), bobcat (Lynx rufus), and coyote (Canis latrans). Sensitive Biological Resources The following describes the sensitive plant and wildlife species present or potentially occurring in suitable habitat within Planning Unit 45 that have been afforded special recognition by federal, state, or local resource conservation agencies and organizations. Also discussed are habitats that are unique, of relatively limited distribution, or of particular value to wildlife. Appendix 1 of this study provides a list of the sensitive plants and wildlife present or potentially occurring on the site. MoorpaMPanning Unit 45 Planning Unit 45 8 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Plants Special status plant surveys were conducted in May and June 1993 as part of the baseline documentation for the draft EIR. Because of the large size of the Specific Plan site, all areas were not surveyed. Representative habitats throughout the Specific Plan within the development boundaries (excluding Planning Unit 45) that potentially supported sensitive plant species were systematically surveyed to determine the presence /absence of sensitive plants. A detailed discussion of the sensitive plant species potentially present can be found in Appendix D of the draft EIR. One sensitive plant species was observed within Planning Unit 45, Fish's milkwort (Polygala comuta var. fishiae). Three additional sensitive plant species were observed within the Specific Plan boundaries and can be expected to occur within suitable habitat in Planning Unit 45. These species are the Catalina mariposa lily (Calochortus catalinae), California spineflower (Mucronea califomica), and California beargrass (Nolina cistomontana). Southern California black walnut (Juglans califomica var. califomica) does not occur within Planning Unit 45. Although not observed during focused surveys on the remainder of the Specific Plan site, suitable habitat for Braunton's milk vetch (Astragalus brauntonn), Blochman's dudleya (Dudleya blochmaniae ssp. blochmaniae), marcescent dudleya (Dudleya cymosa ssp. marcescens), Santa Susana tarplant (Hemizonia minthronii), Ojai fritillary (Fritillaria ojaiensis), and Lyon's pentachaeta ( Pentachaeta 1yonii) occurs within Planning Unit 45. Wildlife Focused surveys within the Specific Plan development boundaries to determine the potential presence or absence of special status wildlife species were conducted between April and May 1993 and in March and April 1996. Because of their secretive nature and ability to avoid detection, the presence or absence of several wildlife species could not be confirmed through focused surveys. Therefore, habitats were examined to assess their potential to support these species. Suitable habitat for two amphibians and eight reptiles occurs within Planning Unit 45. These species are the western spadefoot toad, coast range newt, silvery legless lizard, coastal western whiptail, California horned lizard, two- stripped garter snake, San Bernardino ringneck snake (Diadophis punctatus modestus), San Diego mountain kingsnake (Lampropeltis zonata pulchra), coastal rosy boa, and coast patch -nosed snake. Eighteen sensitive bird species potentially occur within Planning Unit 45; nine of these species were observed during surveys of the Specific Plan site. Sensitive bird species observed within MwWrkWlannirg Unit 45 Planning Unit 45 9 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 6) the Specific Plan site and expected within Planning Unit 45 include the Cooper's hawk (Accipiter coopen), coastal cactus wren (Campylorhynchus brunneicapillus), Bell's sage sparrow (Amphispiza belli bellh), yellow warbler (Dendroica petechia brewsten), California horned lark (Eremophila alpestriachia actia), loggerhead shrike (Lanius ludovicianus), Southern California rufous- crowned sparrow (Aimophila ruficeps canescens), golden eagle (Aquila chrysaetos), and norther harrier (Circus cyaneus). Sensitive bird species potentially present include the coastal California gnatcatcher, white - tailed kite (Elanus caeruleus), yellow- breasted chat (Icteria wens), ferruginous hawk (Buteo regalis), long -eared owl (Asio otus), western burrowing owl (Speotyto cunicularia hypugea), sharp - shinned hawk (Falco striatus), prairie falcon (Falco mexicana), and merlin (Falco columbarius). Several sensitive mammals are known to occur in the vicinity of Planning Unit 45, including the San Diego black - tailed jack rabbit (Lepus californicus bennettl), American badger (Taxidea taxus), pallid bat (Antrozous pallidus), spotted bat (Euderma maculatum), California mastiff bat (Eumops perotis californicus), Pacific Townsend's big -eared bat (Plecotus townsendi townsendi), and San Diego desert woodrat (Neotoma lepida intermedia). Plant Communities Plant communities of special concern include those habitats that support rare, threatened, or endangered plant or wildlife species; are locally diminishing and of special concern to local resource agencies and special interest groups; or, are afforded legal protection through CEQA, Section 1600 of the California Fish and Game Code, Section 404 of the Clean Water Act, and /or both the federal and state Endangered Species Acts. Federal, state, and local agencies recognize coast live oak woodland, coast live oak riparian forest, and coastal sage scrub as habitats of special concern. These habitats are highly valued because they support many special status plant or wildlife species and because they are locally diminishing. In addition, several of these habitat types may be potential jurisdictional wetlands pursuant to Section 404 of the Clean Water Act and Section 1600 of the California Fish and Game Code. Should these areas meet wetland criteria set forth in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands ( USACE 1987), the filling of these wetlands will be controlled by the U.S. Army Corps of Engineers (USAGE) in accordance with Section 404. Habitats occurring along the drainages of Planning Unit 45 may also be subject to Section 1600 of the California Fish and Game Code. Section 1601 of the code requires a Streambed Alteration Agreement for impacts on streambeds and associated riparian vegetation. In addition, the City of Moorpark tree ordinance protects oak, mature, and historic trees. OxyWrkV21anning Unit 45 Planning Unit 45 10 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Wildlife Movement Corridors Currently, wildlife movement within the Specific Plan site (including Planning Unit 45) and in adjacent areas to the east, and north is unrestricted by development. The canyons and ridgelines in the vicinity of Hidden Creek in the southern portion of Planning Unit 45 contain wildlife habitat and movement areas. These areas provide wildlife with foraging habitat, cover, water, and access to adjacent suitable habitat. However, few individuals are expected to use this area strictly as a movement area because westward movement is obstructed by urban development (Moorpark College and additional residential areas to the west). Therefore, wildlife movement through this area is expected to be limited although wildlife may use Hidden Creek as a movement area to reach Alamos Canyon and other eastward destinations. Although diagnostic sign of the coyote, mule deer, and bobcat was found infrequently within the north /south running wooded drainages of Planning Unit 45, these areas may be used as movement areas by various wildlife species. More likely, wildlife use these areas as foraging habitat and cover. Project Impacts The following discussion examines the potential impacts on plant and wildlife resources that may occur as a result of future development of Planning Unit 45. Although no development is proposed at this time as a part of the Hidden Creek Specific Plan (No. 8) project and no design or grading plans have been prepared, a zoning designation has been requested to allow for future golf course use in Planning Unit 45. The following analysis is based on the potential development assumptions that portions of the existing resources within the planning unit would be lost with development after zoning of the area. A worst -case assessment has been made stating that approximately 200 acres of the 450 -acre planning unit would be impacted by a future golf course. Although a "link style" golf course is envisioned, which would be less intrusive and damaging to natural habitat, the 200 -acre figure was used as the analysis factor to ensure that potential effects are not underestimated. For this worst -case hypothetical scenario, of the 200 acres, the assessment assumes that approximately 80 percent of these areas (160 acres) is in the upland plateau portions of the planning unit and the remaining 20 percent of these areas (40 acres) is in the canyon areas. Biological impacts were evaluated in conjunction with those impacts for the Specific Plan and were evaluated based on the same significance criteria as stated in CEQA and discussed in detail in the draft EIR. MoorparklPlammng Unit 45 Planning Unit 45 19 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Impacts on Vegetation To determine the approximate number of acres of the various plant communities that would be potentially impacted by a future golf course, each of the plant communities was assessed as to their geographic location in Planning Unit 45. The plateau portions are dominated by non - native grassland and coastal sage scrub /non- native grassland ecotone. Based on previous assumptions, up to 160 acres of these communities (120 acres of coastal sage scrub /non- native grassland ecotone and 40 acres of non - native grassland) would be impacted by project construction. Non - native grassland is considered locally abundant. Although the coastal sage scrub /non- native grassland ecotone areas contain a percentage of sage scrub plant species, these areas have been severely degraded by past grazing practices, do not contain the biological diversity and structure of the Venturan coastal sage scrub onsite, and have limited potential to support sensitive wildlife species. Therefore, the loss of these communities would not be considered significant. Venturan coastal sage scrub, chaparral, coast live oak woodland, and southern coast live oak riparian forest are the dominant plant community types within the canyon areas of the southern portion of Planning Unit 45. Future implementation of a golf course within Planning Unit 45 would result in the loss of approximately 29 acres of Venturan coastal sage scrub. Because Venturan coastal sage scrub is a limited community, this is considered a significant impact. Approximately 3 acres of chaparral would be removed by project description. Chaparral is considered locally abundant and the loss of this community is not considered significant. Future implementation of a golf course within Planning Unit 45 would impact approximately 6 acres of coast live oak woodland and 2 acres of southern coast live oak riparian forest. Because of the sensitivity of these habitats and their importance to local and regional ecosystems, the loss of any oak community would be significant. In addition, to determine whether these resources would require permit approval by the USACE and /or CDFG, a formal wetland delineation would be required if development was planned that would "fill," hinder flow, or otherwise impact any wetland area. Impacts on Wildlife The natural communities within the Hidden Creek Specific Plan site (including Planning Unit 45) and adjoining areas constitutes a functional ecosystem for wildlife species within the region. The primary impacts of development in Planning Unit 45 on wildlife resources would be the removal of these natural communities and the displacement of wildlife resulting in a less diverse and abundant local faunal populations, as with development of the Specific Plan overall. As was MoorparkVIlaaring unit 48 Planning Unit 45 12 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) mentioned in the draft EIR, the elimination and displacement of animals in Planning Unit 45 is considered a significant impact. Impacts on Sensitive Biological Resources Several plant species have the potential to occur onsite due to the presence of suitable habitat. One CNPS - listed plant species (Fish's milkwort) was observed within Planning Unit 45. No determination of the potential impact to individual species can be made at this time; however, if each of the species presence on the site is assumed, project impacts to sensitive plant species would be considered significant due to the size of a potential golf course in this area. To fully determine the potential project impacts on sensitive plant species, focused surveys should be conducted during the spring as part of the environmental review of a potential future golf course development to confirm their presence or absence from the site. Thirty -five wildlife species which are listed as Federally Protected, Federally Threatened, former Federal Candidate for listing, and California Species of Special Concern are known to or potentially occur within Planning Unit 45. Development of a proposed golf course within Planning Unit 45 may significantly reduce suitable habitat for these sensitive wildlife species. This potential impact would be considered significant. Potential future development of a golf course in Planning Unit 45 could also result in the removal of active raptor nests which are protected under Section 3503.5 of the California Fish and Game Code. The potential loss of any active raptor nest is considered a significant impact. Planning Unit 45 supports sensitive habitats including coast live oak woodland, southern coast live oak riparian forest, and Venturan coastal sage scrub. The potential future development of a golf course within this planning unit would affect approximately 8 acres of coast live oak woodland and southern coast live oak riparian forest. These communities are regionally important because they are limited in distribution and provide suitable habitat for many wildlife species. Additionally, drainages within these habitats may be subject to the jurisdiction of USAGE and CDFG. Consultation with USAGE and CDFG are required prior to filling or altering any onsite wetlands. A detailed wetland delineation may be required as well as USACE permits and/or CDFG agreements prior to any onsite grading. Native live oaks found onsite are protected by the City of Moorpark Municipal Code, Chapter 12.12. Additionally, oak woodlands in California are recognized as a significant resource by resource agencies including the CDFG. Removal of coast live oak habitat would be considered a significant impact. MWMaf*V21anning una as Planning Unit 45 13 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Because the Venturan coastal sage scrub within the vicinity of Planning Unit 45 is known to support or potentially support several sensitive species, the loss of approximately 29 acres of this habitat is considered significant. As previously stated, any development in Planning Unit 45 would require environmental review prior to the approval of any grading or construction activities. Based on a development plan that would be required for submittal and review by the City of Moorpark, a determination would be made if any sensitive habitat would be impacted and if focused surveys for sensitive species would be required. Indirect Impacts on Vegetation and Wildlife Increased noise associated with vehicular traffic, human intrusion into the habitat (including pets), litter, pollutants, and night lighting associated with development of the proposed golf course within Planning Unit 45 would be likely to adversely affect wildlife populations within the immediate vicinity. These impacts, while adverse, would not be expected to reduce any current wildlife populations below self- sustaining levels and are not expected to substantially affect wildlife habitat. Therefore, no significant impacts are expected to occur as a result of indirect impacts. Secondary impacts on coast live oak woodland and southern coast live oak riparian forest could include increased human intrusion and disturbance. Soils in a healthy oak woodland are sensitive to compaction and unmonitored irrigation which can cause a decline in oak health. Uncontrolled, these secondary impacts can be significant. Cumulative Impacts Potential cumulative impacts on biological resources are primarily related to the loss of plant communities and wildlife habitat. Should development occur within Planning Area 45 in the future, such development could cumulatively contribute to the loss of general wildlife habitat, coast live oak woodland, coast live oak riparian forest, and Venturan coastal sage scrub. Based on the information provided in the draft EIR, with respect to the sensitive habitats also found in Planning Unit 45, approximately 19 acres of coast live oak woodland, less than one acre of southern coast live oak riparian forest, and 291 acres of Venturan sage scrub would be impacted by the proposed development within the remainder of the Specific Plan site. Development of a golf course in Planning Unit 45 would increase these areas to approximately 25 acres for coast live oak woodland, over 2 acres for southern coast live oak riparian forest, and approximately 320 acres for Venturan coastal sage scrub. Future development in this planning unit, when considered additive to the proposed development of the Specific Plan, as MoorpafW1annirg Unit 45 Planning Unit 45 14 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) well as other past, present, and reasonably foreseeable future development projects, is considered a significant biological impact. Mitigation Measures This section focuses on the development of mitigation measures for those impacts that may result from future proposed development of a golf course in Planning Unit 45. Strategies to mitigate each impact to a level of less than significant are identified and described. Although measures are the same or similar to those identified for biological resources in the draft EIR, the EIR mitigation measures are broken down by planning units so all of the appropriate mitigation measures relative to Planning Unit 45 are identified below. Modify Mitigation Measure 1 of Section 3, Biological Resources, to include Planning Unit 45 as follows: 1. Resource Management Plan Prior to a determination of application completeness for the first Master Tentative Map, a plan containing procedures and performance standards that must be executed to protect or replace biological resources affected or potentially affected shall be submitted by the project applicant and approved by the City of Moorpark Director of Community Development. This plan is commonly referred to as a Resource Management Plan (REMP). The REMP shall contain a summary of mitigation milestones that will identify the schedule for completion and the party or parties responsible for their implementation. All revegetation plans identified below shall include a 5 -year monitoring program that outlines the procedures for determining the success or failure of the program and reporting requirements for transmitting this information to resources agencies. The REMP shall include, but not be limited to, sub - measures A through M. Each sub - measure falls under a heading of the biological resource affected. Coast Live Oak Woodland and Southern Coast Live Oak Riparian Forest Development in Planning Unit 45 could result in the loss of approximately 8 acres of coast live oak woodland and southern coast live oak riparian forest. Concurrent with the submittal of any tentative tract map application, a tree study, as defined in Chapter 12.12 of the City Municipal Code, with a precise evaluation and mapping of oak and mature trees shall be submitted in accordance with Chapter 12.12 of the Municipal Code. a. Every attempt should be made to minimize grading to reduce the unavoidable affects resulting from the loss of trees. However, avoidance of all tree resources may not be feasible in its entirety for the proposed project. b. Should significant impacts to trees remain after completion of a golf course design, prior to issuance of a grading permit, the protection and replacement requirements of Chapter 12.12 of the Moorpark Municipal Code shall be implemented to reduce MooMark Planning Unit 45 Planning Unit 45 15 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) the level of impact to below significant. Specific tree ordinance guidelines include (1) locating grading in minimum growing areas as required by individual species, (2) no disruption or removal of structural feeder roots, (3) fencing of trees at or beyond their driplines during grading and construction activities, (4) no filling, cutting, development, or compaction of soil within the dripline, and (5) such other measures required by the species of tree to be preserved as recommended by the consulting arborist, horticulturist, or landscape architect. c. Potential coast live oak trees transplant candidates, as determined by a certified arborist, shall be transplanted to an appropriate area identified in the REMP. All potential transplant candidates shall be identified in the REMP. If relocation is not possible for all impacted trees, replacement coast live oak trees shall be planted in suitable locations identified in the REMP. The number and size of replacement trees shall be identified in the REMP. d. A resource management specialist shall be consulted prior to final design and an application completeness determination for a golf course conditional use permit to (a) identify particularly valuable oak and sycamore resources that may be preserved, (b) outline measures to protect or preserve trees within the immediate vicinity of the project, and (c) assist in the design of landscape buffers and transition zones between the project and natural open space areas. e. Construction guidelines shall be developed in the REMP and shall address (1) monitoring of affected resources, (2) construction guidelines specific to tree resources, (3) tree pruning, (4) landscaping and irrigation adjacent to trees, and (5) arboricultural care. Oak trees that cannot be avoided or transplanted shall be replaced. During the preparation of a tree report (required for any proposal for urban development, as defined in Chapter 12.12 of the Municipal Code) for tentative map and development permit applications, an appraised value of each tree shall be established and provided to the City using the most recent edition of the Guide for Establishing Values of Trees and Other Plants prepared by the Council of Tree Landscape Appraisers. The dollar value of the trees removed will be applied to the purchase of replacement trees, their establishment, and maintenance. Where feasible, replacement trees shall consist exclusively of indigenous tree species and shall be certified as being grown from a seed source collected in Ventura County, preferably from the Specific Plan area. Replacement trees shall be of varied size and age classes. A combination of cuttings, seedlings (1- gallon), saplings (5- gallon), and trees (15- gallon, 24 -inch, and 36 -inch box) shall be planted. Replacement trees shall be planted and maintained on site and, if feasible, in the same general area from which the trees were removed. The tree planting shall be supervised in the field by a qualified restoration specialist. The replacement trees shall replace the habitat value of the removed oak woodlands. Replacements shall, for example, be planted adjacent to existing woodlands to provide an additional buffer between development and open space areas, or within the remaining oak woodlands to improve the habitat value of these MooWrkwenrong unit 45 Planning Unit 45 16 Supplemental Study Report Hidden Creek Ranch Speck Plan (No. 8) areas. Alternatively, trees can be planted in currently disturbed areas and graded areas that can support these trees. Replacement trees shall be properly cared for and maintained for 5 years, including irrigation, weed control, and herbivorey protection. All trees replaced shall be monitored for an additional 5 years after tree maintenance is terminated. During monitoring years 6 through 10, tree mortality and general site conditions shall be noted. A report, citing the general conditions and any corrective measures needed, shall be prepared and submitted yearly to the Community Development Director. If a replacement tree dies during the ten -year maintenance and monitoring period, it shall be replaced. The project applicant shall be financially responsible for the maintenance, monitoring, and replacement of all trees planted as mitigation for project impacts through the posting of a specific fund for that purpose. g. The following mitigation measures apply to trees located within 40 feet of grading limits; this measure, when implemented, will protect the long -term viability of those trees. No cutting, grading, filling, trenching or other restructuring of the soil shall take place within the dripline of a preserved oak. Should a trench, retaining wall, or other construction requiring any of these procedures be necessary within the dripline of an oak, a qualified expert shall be present during construction. No oak shall be pruned so that its size or conformation is substantially altered, except as absolutely necessary. All pruning cuts shall be made to lateral branches or at the base of the branch at shoulder rings. Stubbing or dehorning is not permitted. All pruning shall be accomplished by a qualified expert. Landscaping requiring irrigation shall not be planted within the dripline of oaks due to the susceptibility of native oaks to root rot, caused by excessive unseasonable irrigation. The design and installation of landscape irrigation systems outside the dripline of the oaks shall be such that the area within the dripline is not wetted during operation of the system. In addition, surface runoff from impermeable surfaces shall be directed away from oaks; where the natural topography has been altered, provisions should be made for drainage away from trunks of oaks so that water will not pond or collect within the dripline of any oak. Prior to grading, a temporary fence not less than 4 feet in height shall be installed around the protected zone of trees within the 40 -foot zone adjacent to development grading. Fencing shall be in place and inspected, prior to commencement of grading. This fencing shall remain in place throughout the entire period of construction. h. Prior to issuance of a grading permit, a formal wetland delineation, pursuant to a CDFG agreement and USACE permit, shall be conducted. Disruption of riparian habitat requires consultation with both agencies. The USACE and CDFG typically require mitigation plans to be prepared prior to the loss of riparian resources. Mitigation may consist of habitat replacement at a ratio of 1:1 or greater for each acre lost. MooWr*Vllanning Unit as Planning Unit 45 17 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Venturan Coastal Sage Scrub Future development of a golf course within Planning Unit 45 may result in the loss of approximately 29 acres of Venturan coastal sage scrub. Prior to a determination of application completeness for a conditional use permit, the City of Moorpark shall review design plans to determine the most appropriate measures available to offset impacts on Venturan coastal sage scrub. Mitigation measures that may be required can include preservation of avoided scrub by a resource preservation easement, acquisition, or other mechanisms, and the restoration, replacement, or revegetation of removed scrub. The REMP shall outline the planting methodology for the replacement of Venturan coastal sage scrub, if appropriate. Wildlife Habitat/Sensitive Wildlife Species The loss of wildlife habitat by construction of a golf course within Planning Unit 45 is considered a significant impact. j. A minimum of 240 acres of Planning Unit 45 shall be preserved in permanent natural open space. The REMP shall (1) specify boundaries of the preservation areas, (2) provide measures to buffer, control vehicular access, and avoid habitat degradation during construction operations, and (3) formulate guidelines for the permanent protection of preservation /revegetation areas. The selection and implementation of preserved open space areas shall be conducted in coordination with the City of Moorpark and appropriate resources agency personnel (CDFG and USFWS). Management guidelines which shall be incorporated into the REMP include the management of land uses within the immediate vicinity of the natural open space areas. In addition, domestic animals, off -road vehicles, roadway lighting, and recreational activities shall be restricted from the vicinity of the natural open space areas. Raptor Nesting Sites Significant impacts on nesting sites of sensitive raptor species may occur as a result of project implementation. k. If construction and habitat removal is proposed during the raptor breeding season (March to July), a survey shall be conducted for active raptor nests. If active nests are found, no construction activity shall take place within 500 feet of the active nest until the young have fledged (as determined by a qualified raptor biologist). The 500 -foot perimeter around each active nest shall be fenced by appropriate visible fencing material. Trees containing active and non - active nests shall be removed during the non - breeding season only. I. To offset potential impacts on raptor nesting habitat, the REMP shall address raptor habitat management for pre: -.-ved areas that shall include, as appropriate, perch management (retaining dead limbs and trees) and provision of artificial nest boxes or platforms.

Prior to a determination of application completeness for a conditional use permit, the proposed project shall be evaluated by a qualified biologist for potential intrusion on the biological resources. Mitigation Measures Specific to Planning Unit 45 2. Additional Survey Efforts To fully understand the biological resources within Planning Unit 45, focused surveys for the coastal California gnatcatcher, a federally listed threatened species, and sensitive plant species shall be initiated prior to preliminary project designs and submittal of an application of a conditional use permit. The locations of occupied habitat of the gnatcatcher and locations of sensitive plant species will provide the project designers with biological design features worthy of protection and preservation. 3. "Links" Style Golf Course Any golf course constructed in Planning Unit 45 will be a "links" style golf course. Links courses are developed with minimal disturbance to the natural habitat with a green tee area, turfed and green link and landing areas and green cup areas, with native plants remaining in between the green and turf areas. 4. Audubon Cooperative Sanctuary The golf course will be developed in an environmentally sensitive manner in accord with the Audubon Cooperative Sanctuary Program for Golf Course Guidelines as sponsored by the Audubon Society of New York State, Inc. 5. Wildlife Movement Fencing and other impediments will not be placed in areas that will prevent wildlife movement through the canyon bottoms. A wildlife biologist shall review the conceptual and final building, landscaping, and fencing plans for a golf course to ensure that buildings, landscaping, and fencing are not designed in a manner that will impede wildlife movement and migration. The conceptual plan review shall occur prior to a determination of application completeness for a conditional use permit; the final plan review shall occur prior to issuance of a zoning clearance for either building or grading permits for a golf course. MooWrMPlenning unit 45 Planning Unit 45 19 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Level of Significance after Mitigation Because of the habitat loss that could result from development of a proposed golf course within Planning Unit 45 (up to 200 acres), impacts on wildlife habitat and sensitive wildlife species will remain significant after implementation. The feasibility of the implementation of the mitigation options for coast live oak woodland, southern coast live oak riparian forest, and Venturan coastal sage scrub is uncertain at this time; therefore, unavoidable sigNficant impacts will remain, as reported in the draft EIR. Impacts to sensitive raptor species and indirect impacts to vegetation can be mitigated to a level that is considered less than significant. ARCHAEOLOGICAL RESOURCES As a part of the draft EIR identification of archaeological resources in the Specific Plan site, a Phase I cultural resources assessment was conducted by W and S Consultants. The Phase I assessment included an archival records check and literature search through the University of California at Los angles Archaeological Information Center, one of the regional clearinghouses for archeological site records for Southern California. The records check and literature search were supported with field surveys by W and S Consultants. The entire 4,200 - acre Specific Plan site was surveyed; areas above 25 percent grade were less intensively surveyed. The results of the Phase I assessment identified archaeological sites within Planning Unit 45. Because no development is currently proposed in Planning Unit 45 as a part of the Specific Plan project, Phase II test excavations were not conducted in Planning Unit 45. The impact analysis in Section 3.9, Cultural Resources, of the draft EIR identifies that future potential development of the planning unit for land uses such as a golf course could impact archaeological sites in Planning Unit 45. The draft EIR further states that to avoid direct and indirect impacts to archaeological resources in Planning Unit 45, additional archaeological field work will be required before any uses are allowed to occur that could potentially disturb the resources. Mitigation Measures 3 and 4 address the archaeological program for this planning unit which requires Phase II subsurface test -level investigations and surface collections (prior to the approval of any discretionary permit for uses in Planning Unit 45); and a program to reduce indirect impacts associated with increased human presence in the area. As a part of the applicant's request to zone Planning Unit 45 "OS /GC," which would limit use of the site to a links -style golf course and undeveloped open space, a Phase II archaeological study was prepared by W and S Consultants in October 1997. The results of this assessment are discussed below. The sites investigated during the 1997 Phase II study are: CA -VEN -1130, -1137, -1138, -1139, -1140, -1141, -1142, -1143, -1144, and -1147. All of these are prehistoric sites. They are all MoorparWIlanning Unit 45 Planning Unit 45 20 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) located in the southeastern portion of Planning Unit 45, on a series of broad and open mesa -like ridges. Field Methods Phase II archaeological fieldwork at the ten sites investigated in Planning Unit 45 was intended to establish the nature and significance of each site, and to thereby provide baseline data from which a final determination of the disposition of these cultural resources could be made. This required the collection of a representative sample of artifacts and archaeological indicators from each of these cultural resources, the establishment of the vertical and horizontal boundaries of each cultural deposit, and an analysis of the recovered artifact assemblage from these archaeological localities. Procedures followed in the collection of data to establish the nature and significance of the ten sites included mapping, surface collecting of artifacts lying on the ground surface, and test excavation of pits to establish the presence /absence of a subsurface archaeological deposit, as well as to characterize such a deposit if found to be present on a given site. Although these procedures were systematized so that the recovered data would be comparable between each site as well as with previous studies in the region, the magnitude of effort varied somewhat between the ten sites, reflecting the field conditions specific to each locale. The allocation of test pits per archaeological site, and therefore the intensity of subsurface testing at each locale, is indicated by the number of pits excavated at each. These figures are as follows: CA -VEN -1130 —14 pits CA -VEN -1138 — 12 pits CA -VEN -1140 — 12 pits CA -VEN -1142 — 3 pits CA- VEN -1144 — 3 pits CA -VEN -1137 — 8 pits CA -VEN -1139 — 4 pits CA -VEN -1141 — 8 pits CA -VEN -1143 —10 pits CA -VEN -1147 — 4 pits A total of 78 1.1 meter pits were then excavated on the ten sites. Fieldwork Results/Impacts Results from the test excavations are provided below. CA -VEN -1130. The excavation of 14 pits at this site revealed the presence of a relatively shallow subsurface midden deposit localized at the northeastern end of the recorded site are, extending from the top of a low knoll northwards across a shallow swale. This midden deposit MoomarklPlannog Unit 45 Planning Unit 45 21 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) averaged about 40 cm in depth. It covers an area that is 145 meters N -S by 45 meters E -W, for a total site area of 6,525 meters square. No intact subsurface features (e.g., burials, hearths) were discovered during the excavations, but artifacts and dietary remains (principally animal bone) were recovered. Surface collection resulted in the recovery of all extant formal artifacts on the ground. Included among these is a projectile point dating to the Intermediate Period, suggesting that the site dates between about 3,500 and 800 Y.B.P. (Years Before Present). The site appears to represent a small, seasonally occupied village. CA -VEN -1137. A very shallow subsurface midden deposit, averaging only 30 cm in depth, was encountered during the excavation of eight test pits at this site. This deposit was localized in an area measuring 65 meters N -S by 55 meters E -W, or 3,675 meters square. No subsurface features were encountered during the excavation. All formal surface artifacts were collected from the ground surface of this site. This site appears to be a small, Intermediate Period campsite. CA- VEN -1138. Twelve excavation units were placed on this site, three of which proved to have evidence of a shallow midden deposit. This is localized in the approximate middle of the site and measures 60 meters N -S by 100 meters E -W, or 8,000 meters square. Average depth of this midden is only 25 cm. No subsurface features were encountered. All formal artifacts were also collected from the surface of the site. Unlike other sites examined, CA -VEN -1138 appears to represent an Intermediate Period subsurface deposit combined with a very thin Late Drehistoric Period occupation, as indicated by the top 10 cm of the site deposit. Therefore, it dates between 3,500 and approximately 250 Y.B.P., and represents a small campsite. CA -VEN -1139. The four test pits excavated on CA -VEN -1138 showed no evidence of subsurface cultural deposition, indicating that this site is a surface lithic scatter. Surface collection resulted in the recovery of all extant formal artifacts on the site. The site represents a small quarry- workshop associated with a natural quartzite cobble deposit. CA -VEN -1140. Test excavations (12 units) at this site showed that a moderately deep subsurface midden is present in the approximate center of the site's recorded location. This deposit is oblong in shape and measures 130 meters NE -SW by 60 meters NW -SE, or about 7,800 meters square. Average depth of the midden is about 45 cm. No subsurface features were encountered during the excavation. Surface collecting also resulted in the recovery of all formal artifacts from the site surface. Projectile points recovered from the site indicate that it dates to the Intermediate Period. The site appears to represent a small seasonally occupied village. Mowpa-MAanning unit os Planning Unit 45 22 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) CA -VEN -1141. Although eight test pits were excavated on CA -VEN -1141, no evidence for a subsurface deposit was encountered and is considered a surficial lithic scatter. Surface collecting resulted in the recovery of all formal artifacts from the site area. The site appears to represent a quarry/workshop. CA -VEN -1142. Three test pits were dug at this site, none of which had evidence of subsurface archaeological remains. CA -VEN -1142 can be interpreted as a surface lithic scatter, specifically, a small quarry/workshop associated with a natural deposit of quartz cobbles. All surface artifacts were collected from the site. CA -VEN -1143. Although no subsurface features were encountered during the excavation often pits at this site, a small and shallow midden deposit was discovered. This averaged about 25 cm in depth and measures 60 meters N -S by 35 meters E -W, or 2,100 meters square. All surface artifacts were also collected off the site surface. Based on projectile points found during the excavation, this site appears to date to the Intermediate Period and represents a small campsite. CA- VEN -1144. Approximately 80 percent of the area of this site was destroyed by prior grading of an oil pad. Three test pits showed that no subsurface deposit is present at this location. Surface collection resulted in the recovery of extent surface lithics. This site appears to have been a small surficial quarry/workshop associated with a natural outcrop of quartz cobbles. CA -VEN -1147. Four test pits excavated at CA -VEN -1147 failed to reveal any evidence of a subsurface deposit. It appears, instead, to have comprised a surface lithic scatter, specifically, a quarry /workshop associated with a natural outcrop of quartz cobbles. Surface collecting resulted in the recovery of all artifacts from the site surface. The Phase II testing at these ten sites in Planning Unit 45 revealed a widespread but low intensity occupation of the area during the Intermediate Period, or between about 3,500 and 800 Y.B.P. Subsequent to this point, the majority of the habitation sites (villages and camps) were abandoned with the Late Prehistoric Period represented by a thin upper lens at a single site. Therefore, there is a very observable change in the settlement system within the project area at or sometime slightly before about 800 Y.B.P. Notably, this Late Prehistoric Period manifestation is no more intensive than that seen in the earlier- dating deposits. This is important because it suggests that a significant reduction in population size and site use occurred at about the break between the Intermediate and Late Prehistoric Periods, instead of a concentration of the same numbers of people into fewer but larger sites. AAooraar*Oanning Unit 45 Planning Unit 45 23 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) The demographic pattern observed int eh prehistoric record within the Hidden Creek Ranch project area correlates with similar patterns that have recently been identified in the Santa Clara Valley region, to the north. They support the growing evidence for site abandonment and population reduction at the start of the Late Prehistoric Period. It is likely that environmental deterioration —a western North American -wide period of drought at about A.D. 1200 —was the cause of these prehistoric changes. Cumulative Impacts Impacts on onsite cultural resources are site - specific. Although cumulative development in conjunction with past, present, and reasonably foreseeable future development would result in the disturbance of cultural resource sites throughout the region, the City of Moorpark and the County of Ventura require mitigation of impacts to these resources. This includes the collection of artifacts which may contribute to local and regional history and prehistory. As a result, anticipated development in the project region wold not have a significant cumulative impact or result in a significant cumulative loss in regional history or prehistory. Mitigation Measures Sites CA -VEN -1139, -1141, -1142, -1144 and -1147 were found to be low density surface lithic scatters that lacked any subsurface archaeological deposits. Phase II fieldwork at these sites resulted in the recovery of all extant surface artifacts on the site surfaces. This has provided scientifically consequential information from and about these five cultural resources. Per Appendix K of the California Environmental Quality Act (CEQA), this has served to completely and adequately mitigate any adverse impacts due to any development on their site areas (Mitigation Measure 3 in Section 3.9, Cultural Resources, of the EIR). No additional archaeological work be required on these five sites. Mitigation Measure 1 of Section 3.9, Cultural Resources, of the EIR would be modified to require that an archaeological monitor be present should any grading occur near the archaeological sites in Planning Unit 45. Sites CA -VEN -1130, -1137, -1138 and -1143 have intact midden deposits of different sizes. Although no remains of a religious nature were found within these deposits, excavation did reveal artifacts and scientific information useful for the reconstruction of Ventura County's prehistoric past. Development within the defined subsurface deposits areas of these sites has the potential to result in adverse impacts to cultural resources. Following Appendix K of CEQA, such impacts be mitigated either through site avoidance and preservation, preservation with protective capping fills, or through Phase III data recovery (salvage excavations), if site preservation is not an option. MoorparkVDIanMng unit as Planning Unit 45 24 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) The archaeological mitigation program set forth in EIR would be modified to reflect the additional archaeological investigations that have been conducted and the findings of these investigations in Planning Unit 45. The recommended modifications are as follows: 1. During all earth moving activities in the vicinity of archaeological resources (Planning Units 2, 3, 4, 5, 6, 7, 8, 9, 37, 39, and 42A, and 45), the project applicant shall provide written evidence to the City of Moorpark Community Development Director or designated representative that a county - certified archaeologist has been retained, shall be present at the pregrading conference, shall establish procedures for archaeological resource surveillance, and shall establish, in cooperation with the city or landowner, as appropriate, procedures for temporarily halting or redirecting work to permit the sampling, identification, and evaluation of any artifacts found, as appropriate. Prior to the issuance of a grading permit, archaeological requirements shall be incorporated as a note on the grading plan cover sheet. If additional or unexpected archaeological features are discovered, the archaeologist shall report such findings to the city project manager or landowner, as appropriate. If the archaeological resources are found to be significant, the archaeological observer shall determine appropriate actions, in cooperation with the city or landowner, as appropriate, for exploration and /or salvage. The archaeologist shall submit a follow- up report to the City of Moorpark Planning Department, which shall include the period of inspection, an analysis of any artifacts found, and the present repository of the artifacts. Excavated finds shall be offered to the County of Ventura and /or designee, on a first refusal basis. The landowner may retain said finds if written assurance is provided that they will be properly preserved in the county, unless said finds are of special significance, or a museum in the County of Ventura indicates a desire to study and /or display them at this time, in which case items shall be donated to the city, or designee. These actions, as well as final mitigation and disposition of the resources, shall be subject to the approval of the City of Moorpark Community Development Director or designated representative. 2B. Prior to consideration of a conditional use permit for future golf course development in Planning Unit 45, mitigation for direct and indirect impacts to archaeological sites CA -VEN -1130, -1137, -1138, and -1143 shall be identified. The mitigation shall include one of the following: a. Completely avoid disturbance of CA -Ven -1130, -1137, -1138, and - 1143. Should complete avoidance be infeasible, then every effort shall be made to minimize indirect impacts to these sites. This effort shall include the presence of an archaeological monitor onsite during grading and fuel modification brush clearance of Planning Unit 45. Fencing or stakes shall be erected outside of the sites to visually depict the areas to be avoided during construction. Or if avoidance/preservation is not feasible, then: b. Prior to any grading in Planning Unit 45, Phase III field work shall be conducted for archaeological sites CA VEN -1130, -1137, -1138, and -1143 within the potential impact area of development that cannot be avoided The Phase III work will provide sufficient scientific information to fully mitigate the impacts of development on these sites. MoorparkWanning Unrt 45 Planning Unit 45 25 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Level of Significance After Mitigation Should the City of Moorpark zone Planning Unit 45 "OS /GC," any proposed development plan would be subject to environmental review by the city. The evaluation of archaeological resources in Planning Unit 45 and the implementation of the mitigation program set forth in the EIR and as modified above would reduce impacts on archaeological resources to a level that is considered less than significant. OTHER ENVIRONMENTAL ISSUES Earth Resources The assumption has been made that up to 200 acres of the 450 -acre Planning Unit 45 could be associated with a future golf course in this area. Under a hypothetical, worst -case scenario, up to 200 acres would be graded. No impacts beyond those identified in the draft EIR are expected. Mitigation measures identified in the draft EIR would be applied in Planning Unit 45. Water Resources Potential project- specific and cumulative impacts associated with runoff, water quality, and flooding in Planning Unit 45 were addressed in detail in the draft EIR. No additional mitigation measures are required. kkx rpar*0anmng una as Planning Unit 45 26 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) Land Use Mitigation measures identified in the draft EIR associated with potential land use impacts would reduce any significant effects to Planning Unit 45 to a level that is considered less than significant. Aesthetics The mitigation measures in the draft EIR for aesthetic impacts would reduce any aesthetic impacts to Planning Unit 45 to a level that is considered less than significant. Transportation and Circulation Traffic associated with a golf course does not have a strong peak, morning, or afternoon, as trips to a golf course are steady throughout the day, coincident with tee times. Should a golf course be developed in Planning Unit 45 in the future, total trips associated with the Hidden Creek Specific Plan project would increase because of the addition of a second golf course. However, as a part of the project modifications that the applicant has presented to the City of Moorpark to address environmental impacts associated with the project and community and agencies' concerns, the amount of commercial development proposed on the Specific Plan site has been reduced from 29.2 acres to 21.5 acres. The decrease in commercial acreage and square footage is 7.7 acres or approximately 83,853 square feet (based on a floor to area ratio of 0.25). Based on the traffic generation assumptions in the draft EIR, this reduction in commercial square footage would be equivalent to a reduction of approximately 4,235 average daily trips or 26 percent of the project's commercial traffic identified in the draft EIR. Using the traffic generation factor identified in the draft EIR for golf course development, a future golf course in Planning Unit 45 would be expected to generate approximately 1,666 average daily trips. Therefore, should a golf course be developed in Planning Unit 45 in the future, the overall traffic associated with the Hidden Creek Ranch Specific Plan project would be less than the total amount of traffic identified for the project site in the draft EIR. No new traffic impacts are anticipated and no transportation mitigation measures beyond those already associated with project development are expected to be required. Air Quality As with traffic, the reduction in vehicular trips will outweigh the additional trips from a Planning Unit 45 golf course and, therefore, air quality impacts will not be increased. Short-term construction air quality emission will occur and are subject to mitigation as established by the Ventura Air Pollution Control District, as discussed in the EIR. No air quality mitigation MoorcarktRannin9 unit 45 Planning Unit 45 27 Supplemental Study Report Hidden Creek Ranch Specific Plan (No. 8) measures beyond those already associated with project development are expected to be required. Noise Potential noise impacts from future development in Planning Unit 45 would be associated with construction activities and traffic. The reduction in commercial development - related traffic trips and noise associated with those trips will outweigh additional trips and noise from the golf course trips to a Planning Unit 45 golf course. No noise mitigation measures for construction and traffic noise beyond those already associated with project development are expected to be required. Public Services Measures proposed to mitigate project and cumulative impacts to fire protection services, police protection services, water, wastewater, solid waste disposal, energy, and schools associated with Specific Plan No. 8 would be applicable to future golf course development in Planning Unit 45 and would be expected to reduce any potential significant impacts to the degree stated in the EIR. Any fire protection requirement for secondary access can be imposed as a condition of approval for a conditional use permit. No additional impacts from Planning Unit 45 development are anticipated. Public Health and Safety The mitigation measures in the draft EIR for public health and safety impacts are in compliance with state and federal requirements and would reduce any potential impacts to public health and safety as a result of potential future development in Planning Unit 45 to a level that is considered less than significant.

FP(E) or FP(T) - Federally proposed endangered or threatened; taxon proposed by the USFWS for federal listing as threatened or endangered. C1, C2, C2, and FC - Prior to February 28, 1996, there were three categories that pertained to species being considered for listing by the USFWS as threatened or endangered. The definition of the previous candidate categories was as follows: Category 1 (C1) candidate species were those for which existing biological information indicates a listing may be warranted and for which substantial information exists to support the listing. Category 2 (C2) candidate species were those for which existing biological information indicates a listing may be warranted, but for which substantial biological information to support the listing is lacking. Category 3 (C3) candidate species are former candidates and have been grouped into three subcategories extinct (3A), taxonomically invalid or not meeting the USFWS's definition of a "species" (3B), or too widespread or not threatened at this time (3C). The USFWS published in the Federal Register (2/28/96, Federal Register Volume 61, Number 40) a revised definition of species considered candidates for listing. Previous Category 1 candidates are now known simply as "candidate species" (FC). The USFWS determined that the previous Category 2 candidates lacked sufficient information to justify issuance of a proposed rule. Therefore, the USFWS decided to "discontinue the designation of Category 2." Lastly, the USFWS is also discontinuing the use of the Category 3 candidates. Because this is a fairly recent change in the way in which sensitive species are described, both the "old" and "nevi' listing status for each sensitive plant and wildlife species has been identified. California Department of Fish and Game (CDFG) SE - State endangered; taxon for which prospects of survival /reproduction are in immediate jeopardy.

Map Pocket HIDDEN CREEK RANCH SPECIFIC PLAN TREE SURVEY /PLANNING UNrr 45 INTRODUCTION This report documents the tree resources within the souther portion of Planning Unit 45 of the Hidden Creek Ranch Specific Plan (Specific Plan). The entire Specific Plan site is approximately 4,321 acres of primarily undeveloped land, located in the Simi Hills, north of State Route -118, adjacent to Moorpark College (Exhibit 1). The Specific Plan site is located on the U.S. Geological Survey (USGS) 7.5- minute Simi Valley West Quadrangle. The entire Specific Plan site extends northward from College Park Road to a ridgelines running parallel to SR -118. The elevation rises from approximately 600 feet above mean sea level near the southern boundary of the Specific Plan site to approximately 2,300 feet above mean sea level near the northeast corner of the Specific Plan site. The biological composition of the site reflects the region's Mediterranean climate: typically hot, dry summers and cool, wet winters, moderated by coastal influences. Planning Unit 45 of the Specific Plan site is located in the northeastern most portion of the Specific Plan area. The southern portion of Planning Unit 45 (hereafter referred to as the project site) contains approximately 690 acres of non - native grassland, chaparral, coast live oak woodland, Venturan coastal sage scrub, and southern coast live oak riparian forest. The non- native grasses are indicative of repeated disturbances such as grazing, burning, and in some instances discing. The Specific Plan site (including the project site) was heavily grazed until approximately mid -1992, after which the majority of the cattle were moved off the site. TREE EVALUATION METHODOLOGY The tree resources within the project site were surveyed on foot during July and August of 1997, by Project Biologist Don Johnston and Certified Arborist Gerhard Bombe, with the assistance of additional field staff. During these surveys, each tree was characterized and mapped. The tree survey was conducted using a 100 -scale (1 -inch = 100 feet) topographic map. In addition, a 500 -scale (1 inch = 500 feet) color aerial photograph of the site was utilized for orientation. A total of 4,198 mature trees measuring 5 inches or greater in diameter at breast height were evaluated and mapped within the project site. The trees were assessed and evaluated as described below: (1) All trees were assigned an identification number on a site topographic map and evaluation form and a corresponding aluminum tree tag was affixed to the most accessible side of each tree (see Appendix A for tree evaluation forms). Trees unapproachable because of dense poison oak (Toxicodendron diversilobum) surrounding the tree or steep and unstable terrain were not tagged. Of the 4,198 HIDDEN CREEK RANCH SPECIFIC PLAN Pagel of 10 TREE SURVEY/ PLANNING UNIT 45 trees within the project site, approximately 4% of the trees onsite were not tagged. These untagged trees were nevertheless assigned a number, plotted on the project map, designated as "untagged" on the evaluation sheet, and evaluated. (2) Each tree was identified by both its common name and scientific name. For ease of reading, the common and scientific names are used together upon first mention in the text, with the common name used during the remainder of the text. In Appendix A, only the scientific name has been used. (3) The diameter of each tree trunk was measured 4' /z feet above mean natural grade; multiple trunks that branched below 4' /z feet were measures separately. (4) The height of each tree was estimated. (5) The average diameter of each tree's canopy was estimated. (6) Each tree was categorized by crown class (an evaluation of the tree's crown relative to the crowns of adjacent trees). The crown classes are as follows: Dominant - A tree considerably taller than adjacent trees or isolated from competitors for light. Co- dominant - A tree about the same height as adjacent trees, with sides of its crown receiving only limited light. Intermediate - A tree with a crown well beneath taller trees, which receives limited direct light, often only at mid -day. Sub - dominant - A tree completely overtopped by nearby trees, receiving only diffused light. (7) A visual assessment of the aesthetic qualities of each tree was performed. Aesthetic quality was measured on a scale of "A" to "F ". "A" trees possessed the ideal canopy formation, foliage cover, and texture for the species. A tree with an "F" rating had few to no positive aesthetic qualities. (8) The health of each tree was assessed based on visual evidence of vigor, such as the amount of foliage, leaf color and size, presence of branch or twig dieback, severity of insect infestation, the presence of disease, heart rot, fire damage, HIDDEN CREEK RANCH SPECIFIC PLAN Page 2 of 10 Pr ject Location Map Planning Unit 45 /Hidden Creek Ranch Specific Plan Exhibit 1 ANORTH /No Scale Source: MBA /1995 TREE SURVEY /PLANNING UNTT 45 mechanical damage, amount of new growth, appearance of bark, and rate of callous development over wounds. The health assessment also considered such elements as the presence of decay, weak branch attachments, the percent of cross - section areas of the trunk that are vacant because of cavity, the percent of the circumference of the trunk that has been wounded, and the presence of exposed roots from soil erosion. The overall health of each tree was summarized in a health rating. The trees were rated on a scale of "A" to "F„ as follows: A - An outstanding tree. Healthy, vigorous tree, reasonably free from signs and symptoms of disease. B - A good tree. A tree with minor dieback, reduced vigor, and /or insect problems. C - An average tree. A tree with a minor amount of twig and small branch dieback, thinning at the crown, and wounds are slow to heal. D - A tree below average. A tree with dieback of major limbs, large wounds, little callous growth, extensive decay, few leaves, excessive lean, unstable, dead wood in higher branches, and extensive undermining erosion. F - A dead tree. DESCRIPTION OF TREE RESOURCES Within the project site, five plant communities were identified and characterized. These plant communities include chaparral, non - native grassland, coast live oak woodland, Venturan coastal sage scrub, and southern coast live oak riparian forest. Of the five plant communities on site, only the coast live oak woodland and southern coast live oak riparian forest support the majority of the tree resources onsite. In some instances these areas may intergrade with the chaparral or sage scrub; however, these areas are fairly limited and almost always occur in close proximity to large woodland areas. The following discussion describes the coast live oak woodland/southern coast live oak riparian forest and the tree resources present. HIDDEN CREEK RANCH SPECIFIC PLAN Page 3 of 10 TREE SURVEY /Pi ANMNG UNrr 45 COAST LIVE OAK WOODLAND /SOUTHERN COAST LIVE OAK RIPARIAN FOREST PLANT RESOURCES Coast live oak woodland and southern coast live oak riparian forest occurs on gentle slopes, along intermittent streams, and in protected canyons. On steep slopes, the coast live oak woodland intergrades with chaparral and sage scrub communities. The oak woodland and forest distribution onsite includes areas of oak forest (where canopies overlap), oak woodland (where canopies range from 50 to 75 percent cover), and oak savanna (where the canopies are well - spaced). Population demographics include trees averaging approximately 10 inches diameter at breast height, with occasional historic trees (greater than 36 inches at breast height) at scattered locations throughout the site. Tree regeneration varies over the site. Populations on steep slopes show more seedlings and saplings than populations associated with gentle and moderate slopes. Presumably, this is due to less intensive grazing pressure in these areas. The tree resources on the project site occur within the coat live oak woodlands along canyon bottoms and adjacent slopes of four north -south trending canyons on the eastern portion of the Specific Plan area. The dominant tree species in the coast live oak woodland is the coast live oak (Quercus agrifolia). The understory in these areas range from dense shrubby undergrowth to non - native grassland species. Understory shrubs include snowbery (Symphoricarpos mollis), wild cucumber (Marah macrocarpus), mugwort (Artemisia douglasiana), Mexican elderberry (Sambucus mexicana), black sage (Salvia mellifera), tree tobacco (Nicotiana glauca), big - podded ceanothus ( Ceanothus megacarpus), scrub oak (Quercus dumosa), chamise (Adenostoma fasciculatum), poison oak, holly -leaf redberry (Rhamnus ilicifolia), toyon (Heteromeles arbutifolia), and laurel sumac (Malosma laurina). Other species occurring infrequently in the oak woodland include California buckwheat (Eriogonum fasciculatum), mesa bushmallow (Malacothamnus fasciculatus), coastal prickly pear (Opuntia littoralis), lemonadeberry (Rhus integrifolia), horehound (Marrubium vulgare), California peony (Paeonia califomica), coast paintbrush (Castilleja affrnis), California fuchsia (Epilobium canum), and oak mistletoe (Phoradendron villosum). Where the canopy is sparse, occasional grasses and herbs occur including Mediterranean schismus ( Schismus barbatus), wild oat (Avena fatua), slender oat (Avena barbata), soft chess (Bromus hordeaceus), foxtail chess (Bromus madritensis ssp. rubens), and ripgut grass (Bromus diandrus). In the more moist areas of the southern coast live oak riparian forest, western sycamore (Plantanus racemosa), arroyo willow (Salix lasiolepis), golden willow (Salix lucida ssp. lasiandra), and Freemont's cottonwood (Populus fremontit) are dominant. The understory associated with the intermittent drainage includes Indian rush (Juncus texti /is), mulefat (Baccharis salicifolia), wild rose (Rosa califomica), snowberry, pointed rush (Juncus oxymeris), HIDDEN CREEK RANCH SPECg7C PLAN Page 4 of 10 TREE SURVEY /PLANNING UNIT 45 water -cress (Rorippa nasturtium - aquaticum), and poison oak. SOIL CONDITIONS Grazing is common throughout the project site. Grazing activities have the tendency to prevent seedling emergence, although some oak, sycamore, and willow regeneration was observed in portions of the woodland areas. Grazing practices have resulted in very erosive soils conditions, most likely die to the lack of understory vegetation that would normally have stabilized the soil. Soils within the woodland areas are high in organic matter and provide beneficial soil organisms, which are crucial to the continued health and natural regeneration of the woodland areas. GENERAL HEALTH OF WOODLAND Within the project site, old fire damage was noted on a large proportion of the trees. This often resulted in trees with extensive cavities and heart rot. Many trees also had major broken branches, dead wood, and insect infestation. Mechanical damage, such as barbed wire cuts, were seen on several trees. Several pest normally associated with woodland areas were present on some of the trees. These pest are noted on the tree evaluation form only if populations were larger than normal. However, none of the pest noted require treatment at this time. In general, the trees on the project site are in good to average health, although extensive fire damage and cattle grazing have damaged many of the trees and habitat of the area. WILDLIFE RESOURCES The coast live oak woodland and southern coast live oak riparian forest on the project site have the potential to support several frog, toad, and salamander species. Amphibian species potentially occurring in these areas include the western toad (Bufo boreas), Pacific tree frog (Hyla regilla),Monterey salamander (Ensatina eschscholizi eschscholizi), Pacific slender salamander (Batrachoseps pacificus), black - bellied salamander (Batrachoseps nigriventris), arboreal salamander (Aneides lugubris), and coast range newt (Taricha torosa torosa). The woodland/forest communities also provide habitat for the side - blotched lizard (Uta stansburiana), western fence lizard (Sceloporus occidentalis), western skink (Eumeces skiltonianus), southern alligator lizard (Gerrhonotus multicarinatus), coastal western whiptail (Cnemidophorus tigris multiscutatus), gopher snake (Pituophis melanoleucus), common kingsnake (Lampropeltis getulus), and western rattlesnake (Crotalus viridis). Suitable foraging and nesting habitat for many species of birds occurs within the woodland and forest areas of the project site. Species observed during the tree surveys include the scrub jay HIDDEN CREEK RANCH SPECIFIC PLAN Page 5 of 10 TREE SuRvEY /PL.ANNiNG UNrr 45 (Aphelocoma coerulescens), bushtit (Psaltriparus minimus), western bluebird (Sialia mexicana), ash - throated flycatcher (Myiarchus cinerascens), California thrasher (Toxostoma redivivum), wrentit (Chamaea fasciata),Costa's hummingbird (Calypte costae),Lazuli bunting (Passerina amoena), and red- tailed hawk (Buteo jamaicensis). The woodland and forest habitats provide essential cover and foraging habitat and often a permanent or intermittent water supply that are required by many of the region's mammals. Small- and medium -sized mammals observed or expected in these habitats on the site include the pallid bat (Antrozous pallidus), Brazilian free - tailed bat (Tadarida brasiliensis), western mastiff bat (Eumops perotis), raccoon (Procyon lotor), striped skunk (Mephitis mephitis), and dusky - footed woodrat (Neotoma fuscipes). Larger mammals also expected or observed include the mountain lion (Fells concolor), bobcat (Lynx rufus), gray fox ( Urocyon cinereoargenteus), mule deer (Odocoileus hemionus), badger (Taxidea taxus), and coyote (Canis latrans). Mountain lion tracks and scratch marks on western sycamore trees were observed within the project site. TREE RESOURCES A total of 4,198 trees are located within the project site, including 3,892 coast live oak, 190 western sycamore, 74 willow, 2 Freemont's cottonwood, 13 toyon, 8 Mexican elderberry, and 19 scrub oak. Table 1 summarizes the number of trees by species that are present within the project site.

Coast live oaks usually range from 20 to 40 feet in height, but may reach as high as 80 feet or more. One trunk usually emerges from the soil and forks into larger, wide - spreading branches extending outward horizontally. Multi -trunk trees are not uncommon and are frequently the result of fire damage. HIDDEN CREEK RANCH SPECIFIC PLAN Page 6 of 10 TREE SURVEY /PLANNING UNIT 45 The crowns of these oak trees are broad and domed shaped, with large branches that may reach the ground. The leaves are holly -like in shape and form a dense canopy. Coast live oaks primarily occur as dense woodlands along canyon drainages, or in savannah type habitats on valley foothills or alluvial plains. A total of 3,892 coast live oak trees occur within the project site. An average tree onsite has a total truck diameter of 20 inches, is 27 feet in height, has a canopy spread of 26 feet, with a co- dominant crown class, and a C aesthetic, and C health rating. Table 2 summarizes the average and maximum measurements of the total diameter, height, and canopy and Table 3 summarizes the aesthetic and health ratings of the various tree species within the project site.

Western sycamores are found in areas of wet soil; within streambanks in valleys, foothills, and mountains. These trees are commonly planted in parks and residential development areas as ornamental and shade trees. The tree trunks are buff colored and often divide into spreading or leaning secondary trunks. The branches are smooth and are often gracefully twisted and contoured. The western sycamore leaves are deeply lobed and yellowish green.

HIDDEN CREEK RANCH SPECIFIC PLAN Page 8 of 10 TREE SURVEY /PLANNING UNrr 45 Will Willows occur in mostly cooler climates with a perennial or intermittent water source such as along streams, wet places, and at the edges of salt marshes. Willow leaves are narrow and deciduous, with bark that is generally smooth, and tree canopies that are generally straight and narrow. Willows on the project site include both the arroyo willow and golden willow. A total of 74 willow trees occur within the project site. An average tree onsite has a total truck diameter of 13 inches, is 26 feet in height, has a canopy spread of 22 feet, with a co- dominant crown class, and a C aesthetic, and C health rating. Freemont's Cottonwood Freemont's cottonwood is a tree with broad, flattened, open crown of large, widely spreading branches. These trees generally occur in streams with wet soils, often with sycamores, willows, and alders (Alnus sp.). Freemont's cottonwoods have shinny yellow -green leaves that turn bright yellow in autumn. Cottonwoods on the project site were limited to the upper reaches of the westernmost canyon. A total of 2 Freemont's cottonwood trees with trunk diameters over 5 inches were present within a grove of approximately 12 cottonwoods with trunk diameters less then 5 inches. An average tree onsite has a total truck diameter of 8 inches, is 45 feet in height, has a canopy spread of 40 feet, with a co- dominant crown class, and a B aesthetic, and B health rating. Toyon Toyon, sometimes called "Christmas berry', is generally considered a large scrub but can grow in a tree form. The leaves of the toyon are evergreen, leathery, and have saw - toothed edges. Toyon are a common shrub/tree in the chaparral and, to a lesser extent, scrub communities on the project site. A total of 13 toyons in tree form occur within the project site. An average tree onsite has a total truck diameter of 19 inches, is 20 feet in height, has a canopy spread of 25 feet, with a co- dominant crown class, and a B/C aesthetic, and C health rating. Mexican ElderbeMl Mexican elderberry is a large shrub or a small tree commonly occurring within the chaparral, scrub, and woodland communities on the project site.

These sites are CA -VEN -1130, -1137, -1138, -1139, -1140, -1141, -1142, -1143, -1144 and -1147. Five of these sites (CA -VEN -1130, -1137, -1138, - 1140 and -1143) proved to contain small but intact subsurface midden deposits. They are interpreted as Intermediate Period (3500 - 800 years before present) habitations or camps. The remaining five sites are all small surface lithic scatters. Recommendations for the management of each of these cultural resources are proposed.

This project was intended to determine the size, nature and significance of these ten prehistoric archaeological sites and thereby to provide baseline data from which an assessment of potential adverse impacts to these resources could be made. These data have been employed to develop final management recommendations for the treatment of these cultural resources. This study was conducted by W & S Consultants during the Summer and Fall of 1997. David S. Whitley, Ph.D., and Joseph M. Simon served as principal investigators for the project; while the laboratory analyses were conducted by Tamara K. Whitley, M.A., and D.S. Whitley. This report was prepared by D.S. Whitley and Simon. Richard Angulo, representing the California Indian Foundation, served as Native American monitor and liaison for the project. The remainder of this chapter provides environmental and cultural background to the prehistory of the region, including a summary of previous archaeological research conducted in this region; and descriptions of the ten sites considered in this study. This is followed by the field methods used at each of the sites tested during this field program, along with summaries of the field results. We then turn to an assessment of the artifact assemblages recovered from each site, and certain of the analytical conclusions derived therefrom. We conclude with final recommendations for each of the ten cultural resources considered during this Phase II study. 1 1.2 Environmental and Cultural Overview 1.21 Environmental Background & Site Descriptions Archaeological sites CA -VEN -1130, -1137, -1138, -1139, -1140, -1141, -1142, -1143, - 1144 and -1147 are located within the proposed Hidden Creek Ranch project area, City of Moorpark, Ventura County, California (Figure 1). This study area lies on the southern slopes and foothills of Big Mountain, northeast of the town center of Moorpark proper. The general area containing these ten archaeological sites is located on the southeastern side of the Hidden Creek Ranch, with Moorpark College and adjacent housing tracts to the west, and a major but unnamed southwest - northeast trending arroyo tributary to Arroyo Simi to the south and east of the sites. The portion of the study area containing these ten archaeological sites consists of a series of wide mesa -like ridges dissected by intervening arroyos. These mesas extend southwards off Big Mountain, with the intervening arroyos, correspondingly, running north- south. The mesas are truncated at their southern ends by the large unnamed tributary to Arroyo. Simi, noted above, itself presumably following an' old earthquake fault scarp which has helped elevate the mesa -like ridges. Elevation in the area of the sites ranges from approximately 800 to 900 feet a.s.l.; arroyo bottoms, immediately adjacent to the sites, drop to about 760 feet. Although historic and recent land -use changes have altered the environment considerably from what existed during prehistoric times, at least four major plant associations probably characterized the region containing these sites during the aboriginal period. These are chaparral, coastal sage scrub, southern oak woodlands, and riparian associations (cf. Muntz 1974). The chaparral association covers steeper slopes with poorly developed soils and xeric conditions, and is present in some areas on the arroyo sides. It includes the following species: California sagebrush (Artemisia californica), white sage (Salvia mellifera), black sage (S. a lip ana), purple or white - leaved sage (S. Leucolhyla), California encilia ( Encilia californica), California buckwheat (Erioaonum fasciculatUm), chamise 2 (Adneostoma fasciculatum), buckbrush (Ceanothus cuneatus), scrub oak (Quercus dumosa), toyon (Heteromeles arbutifolia), mountain mahogany (Cercocarlus betuloides), lemonade sumac (Rhus integrifolia) and sugar sumac R. v ). This is a particularly common association in the West Ranch study area. The coastal sage scrub community is the climax community for portions of inland - coastal southern California. It is generally composed of coast buckwheat (Eri g num cinereum) and wild buckwheat (E. fasciculatum), along with black sage (Salvia li n , common hazardia (Ha Ig_ogapgus sauarrosus), prickly phlox (Le too dactylon californicum), yucca (Yucca whipplei) and California sagebrush (Artemisia californica) as major constituents. Although both of the above plant associations were undoubtedly of subsistence importance to the aboriginal population of the region, the third association, the southern oak woodland, may have been of primary significance in the inland zones adjacent to the coastal strip. This results because of the great importance placed on the acorn as a food staple by Native Californians (Kroeber 1925), and the rarity of this resource on the coastal side of the Santa Monica Mountains. The association is characterized by the coast live oak (Quercus lobata) and the valley oak Q agrifolia), but also would have included various species of native grasses. Although currently restricted in distribution, this association may once have been found across the broad mesas, which currently contain a few extant oak trees. Historical disking and grazing in these areas, however, makes any certain determination difficult. The fourth and final plant association consists of riparian habitats, which are localized and poorly diversified woodlands found in areas of perennial moisture. They include such species as arroyo willow (Salix lasiolepsi), mule fat (Baccharis glutinosa), willow dock (Rumex salicifolius), swamp knotweed (Polyaonum coccineum), nettle ( r i holosericea), cocklebur (Xanthium strumarium) and rabbitsfoot grass (Polygoaon monspeiensis). Though this plant association is limited in distribution, it can still be considered to have had significant economic importance in aboriginal times, especially in terms of the acquisition of raw materials for items like baskets, cordage and netting. Small riparian habitats in present in portions of the unnamed tributary to Arroyo Simi, lying to the south and east of the area containing the six archaeological sites. All of the sites considered during the Phase II study were first discovered during a recent Phase I survey of the property (W & S Consultants 1994a). At that time, they were described as follows. CA -VEN -1130 - This site was discovered on a broad open ridge about 3.5 km northeast of Moorpark College. It was believed to consist of a large midden deposit, much of which may have being buried by ongoing colluvial processes. We noted manos, hammerstones, fire - cracked rock, a boulder grinding slick, and various classes of debitage on the site, most of which were revealed in rodent -hole backdirt piles. Notably, no shell or faunal remains were observed on the groundsurface. The site appeared to be largely intact, especially inasmuch as colluvial burial may have protected it even from the disking that has occurred at this locale. The area of the site was estimated to be 31,250 m2. CA -VEN -1137 - This site was interpreted as a small quarry workshop associated with a lag deposit of cobbles. It was also thought to possibly include a small midden deposit in the approximate middle of the surface scatter area. We noted fused shale and quartzite debitage, and core /cobble complex hammerstones and choppers on the site. It was in good condition. The estimate of the site area was 11,700 m2. CA -VEN -1138 - This site was found on the same open ridge /mesa as, and slightly southwest of, CA -VEN -1130. It was interpreted as a large quarry workshop associated with a lag cobble deposit, and appeared to contain two small midden patches approximately in the middle of the larger surface scatter. Artifacts noted on the surface of the site included a Northern Side Notched -like dart point of fused shale, a mano, and fused shale and quartzite debitage. The point suggests that the site dates at least in part to the period from 1500 B.C. to A.D. 500. The site was believed to be in good condition, and was estimated to cover 52,500 m2. 4 CA -VEN -1139 - This site was interpreted as a low density lithic scatter associated with a lag cobble deposit. It was found on an open, flat ridge immediately northeast of CA -VEN -1130. We noted quartzite primary flakes on the site, along with an obsidian arrow point base. The arrow base was a Cottonwood - triangular -like type, probably post- dating A.D. 1200. It was made from a distinctive green obsidian that is not typical of the Coso obsidian that is most common in southern California coastal sites. The site was believed to be in good condition, but it was felt unlikely that a subsurface archaeological deposit was present at this locale. Estimated size of site was 15,000 m2. CA -VEN -1140 - Located due east of CA- VEN -1130, on another broad, open ridge /mesa, CA -VEN -1140 appeared to represent a large midden deposit surrounded by a larger surface scatter. As with certain of the other sites within the Hidden Creek Ranch study area, the midden deposit at this site also appeared to be partly buried by natural colluvial processes. We noted what we believed to be manos, hammerstones and debitage of fused shale, chert, quartzite and fine - grained volcanics on the site. No temporal diagnostics were identified here, precluding any estimate of temporal placement. The site condition was considered to be moderate to good, inasmuch as a road has been graded through the site, and its surface had been disked. We estimated the site area at 37,500 m2. CA -VEN -1141 - This site was discovered slightly south of the previous archaeological deposit, along the same open ridge /mesa. It consisted of a medium density quarry workshop associated with a lag deposit of natural cobbles. Hammerstones and debitage of chert, quartzite and fused shale were noted on the groundsurface. Based on the surface evidence and geomorphological context, it appeared that the site did not contain a subsurface deposit. The integrity of the site was considered to be moderate to poor: the north -south road graded on this ridge /mesa appeared to have disturbed a significant portion of this site. Its size was estimated at 12,025 m2. 5 CA -VEN -1142 - This site was found to the east of CA -VEN -1140, separated from it by two small arroyos. It was interpreted as a low density quarry workshop on a flat at the southern end of a ridge, associated with a lag cobble deposit. Quartzite primary flakes and angular shatter were noted on the groundsurface, and it appeared unlikely that a subsurface deposit was present at this locale. Site integrity was thought to be good. Site size was estimated at 4500 m2. CA -VEN -1143 - This site was located to the south of CA -VEN -1140 and -1141. It appeared to consist of a small midden deposit associated with a quarry workshop. A natural deposit of lag cobbles was present alongside a portion of this site. We noted a biface mano, metate fragment, hammerstone, and quartzite and fused shale debitage on the site. As with CA -VEN -1141, site integrity was considered moderate to poor; again, due to the impact of the graded road on the site. We estimated the site size as 12,500 m2. CA -VEN -1144 - This site was considered a small, heavily disturbed resource located at the southern end of the mesa/ridge containing CA -VEN -1140, -1141 and - 1143. When found, CA -VEN -1144 consisted of a low density surface scatter containing a crude chert uniface and fused shale and quartzite debitage. It appeared unlikely that a subsurface deposit was present at this locale. The site may once have extended further east and south on the ridgeline; however, a dirt road and the grading of an oil pad have disturbed the groundsurface in this area. We estimated the extant size of the site at 10,000 m2. CA -VEN -1147 - This site was interpreted as a small chipping station /lithic scatter associated with a lag cobble deposit. We noted a core and three associated primary flakes on the site, with additional debitage in the immediate vicinity. A subsurface deposit was considered unlikely at this locale. The site was thought to be in good condition and was estimated to be 7500 m2 in size. 1.22 Ethnographic Background The Moorpark region, including the Hidden Creek Ranch study area, lies within the territory of the Chumash ethnolinguistic group (Kroeber 1925). These were Hokan speaking people, who occupied the area from Topanga Canyon northwest to approximately San Luis Obispo along the coast, and inland to Piru Creek, along the Santa Clara Valley (to the north of the study area), and to the edge of the San Fernando Valley (in the Simi Corridor). Because of their location in an area of early Spanish missionization, Chumash culture and lifeways were heavily disrupted prior to any modern efforts at ethnographic research, hence our knowledge of them is limited. However, based on fragmentary records and various means of inferential and analogical studies, a certain amount can be reconstructed about their way of life. The Chumash followed a hunting - gathering- fishing subsistence pattern, which incorporated a heavy reliance on maritime resources, including pelagic and littoral fishes, and shellfish. Indeed, the bountiful sea resources that they were able to exploit may have been a key factor in their evolutionary success (Landberg 1965): at the time of the arrival of the Spanish they had reached levels of population density, and complexities in social organization, unequaled worldwide by other non - farming groups (Moratto 1984:118). These included permanent coastal villages along the Channel Islands area containing as many as 1000 inhabitants (Brown 1963), as well as a hierarchical sociopolitical organization consisting of at least two major chiefdoms (Whitley and Beaudry 1991). Further, based on recent reconstructions using mission registers, the Chumash appear to be have a matrilocal, and perhaps matrilineal, clan - based society (Johnson 1988). It is likely that the study region was a part of a large political body, probably a simple chiefdom, headquartered at Muwu. at modern Point Mugu (Whitley and Clewlow 1979). This was known as Lula in a domain whose limits stretched from the southeastern extreme of Chumash territory to just beyond modern Santa Barbara, at Dos Pueblos. According to oral traditions, Lula inn was ruled (and perhaps created) by a lineage of Santa Cruz Islanders; "Chumash ", in fact, is a word that means "islander'. Its use as the generic name for this Hokan language attests to the 7 importance of island groups throughout the Chumash realm. 1.23 Archaeological Background and Previous Work The regional prehistoric record was first defined in a chronological scheme that has its origins in the research of D.B. Rogers (1929), working on the Channel Islands and the Santa Barbara coastline. At a later date, Rogers' scheme was modified in terminology and improved with additional and more detailed data and radiocarbon dates by W.J. Wallace (1955). Modifications have been made subsequently; notably, by King (1981) who, using an analogy with Central California chronology, proposed again a different terminology than that suggested by Wallace. However, Wallace's terminology remains intact throughout most of southern California, and easily accommodates recent refinements in the chronology. Wallace's chronology for southern coastal California includes four time periods, the earliest of which (Early Man /Big Game Hunting period) was considered speculative, and thought to correlate with the end of the Pleistocene. It is likely that occupation of the southern California coastal region occurred during this early time period, particularly given that there is growing evidence for Late Pleistocene occupation of the desert portions of California (e.g., Whitley and Dorn 1988, 1993). Currently, the only evidence of such in the coastal zone has been limited to a few discoveries of fluted projectile points, found in isolated locales (e.g., Erlandson et al 1987). However, the characteristic geomorphological instability of the California coastline and Transverse Mountain Ranges, combined with the major change in erosional /degradational regimes that occurred at the end of the Pleistocene, does not favor the preservation of remains from this period in inland/coastal or coastal California proper (cf. Whitley and Dorn 1993). With the transition towards a modern environment, starting approximately 9 to 10 thousand years ago, however, an adaptation referred to as the Early Millingstone period (or Early Horizon) began and is evident in the archaeological record. Most sites of this stage date between 8500 and 3500 years in age, and are dominated by E? assemblages containing large numbers of groundstone artifacts, along with crude choppers and other core /cobble tools, including the so- called "scraper plane". This assemblage has been thought to represent an adaptation to gathered foods, especially a reliance on hard - shelled seeds. More recently, it has been suggested that scraper planes, in particular, may have served in the processing of agave (Kowta 1969; Sails 1985); that the association of groundstone and core /cobble tools represents a generalized plant processing toolkit, rather than one emphasizing hard - seeds, per se (Whitley 1979a), and one that was used in appropriate environmental settings throughout the prehistoric past. That is, that the so- called early millingstone toolkit is environmentally rather than chronologically specific and reflects localized exploitation patterns, rather than a wide - ranging adaptational strategy (Leonard 1971). However, on the coastal strip, per se, there continues to be evidence that at least some such sites date to the earlier end of the time - frame, and are generally located on terraces and mesas, above the coastal verge. Recent studies by Erlandson (1988a; see also Erlandson and Colton 1991), further, provide evidence of a significant, even if small, population of coastal hunters - gatherers in the region before 7000 years ago, or at the beginning of the Early Millingstone period. He has shown that these were neither Big Game hunters, nor specialized, hard -seed gatherers, but instead generalized foragers that relied on a variety of different kinds of terrestrial, coastal and marine resources, and that they were adapted to estuarine embayments that have long -since disappeared from the local environment. Further, his evidence indicates that their primary protein sources were shellfish and other marine resources. Extending a pattern first identified by Meighan (1959) on the Channel Islands, in other words, this suggests that the adaptation to the seashore is a very ancient and long -lived tradition in local prehistory. Following the Early Millingstone, a transitional stage, referred to as the Intermediate period (or Middle Horizon), occurred. It is believed to have gotten underway about 4000 to 3500 years ago, and to have lasted until about AD 1200 (cf. Arnold 1990:112). It is marked on the coast by a growing exploitation of marine resources, 9 the appearance of the hopper mortar and stone bowl /mortar, and a diversification and an increase in the number of chipped stone tools. Projectile points, in particular, are more common at sites than previously, while artifacts such as fish hooks and bone gorges also appear. Further, there is substantial evidence that it was at the early end of this Intermediate period that inland sites, such as those found in the Conejo Corridor on the north side of the Santa Monica Mountains (discussed below), were first established and occupied, suggesting the exploitation of more varied environments and perhaps an increase in population (Whitley and Beaudry 1991; Whitley et al n.d.), as well as a movement of coastal sites down towards the beaches. In general, however, the Intermediate period can be argued to have set the stage for the accelerated changes that took place immediately following it. With the transition to the Late Prehistoric period at approximately A.D. 1200, following the earlier appearance of the bow and arrow (around A.D. 500) which represented a major reduction in the size of projectile points, along with certain changes in bead types, we can correlate local prehistory with Chumash society as described (even if in abbreviated form) by early chroniclers and missionaries. However, this is not to suggest that society was in any way static, for the transition to the Late Prehistoric period was marked by the evolution and eventual dominance of a sophisticated maritime economy. Further, the rise in Chumash social complexity has been shown to have been associated with the development of craft specialization, involving the use of standardized micro - drills to mass produce shell beads on Santa Cruz Island (Arnold 1987). This occurred sometime around A.D. 1200, and resulted in the Lula in chiefdom noted previously. While the ten sites considered in this current study must be viewed within this general prehistoric and ethnohistoric context, it is nonetheless true that the reconstruction of Chumash prehistory and ethnohistory have largely been based on coastal evidence. That is, sites and minor regions inland from the coast obviously vary from those on the coastal strip (lacking, for example, access to coastal and maritime resources) and therefore exhibit not only some differences in terms of general site characteristics and adaptational trajectories, but differences in general chronological parameters too (W & S Consultants 1985; Whitley 1985). 10 The Moorpark region is located in an inland area generally referred to as the Simi Corridor. This comprises part of a series of east -west trending valleys and intervening hill systems lying northward (and therefore inland) of the Santa Monica Mountains and Conejo Corridor. It includes the Simi Valley proper, and the Tierra Rejada, Little Simi and the Santa Rosa Valleys, all of which are tributary to the Calleguas Creek drainage. Although little archaeological research in the Simi Valley /Moorpark area and Simi Corridor has been published, the prehistory of this area may be profitably compared to that of the adjacent Conejo Corridor, located immediately to the south, and to the Santa Clara Valley, to the north. Using evidence from the Conejo Corridor and Santa Clara Valley as a model, and unlike the Chumash region in a more general sense, the first indication of aboriginal occupation in this inland area appears to date to the beginning of the Intermediate period, or from about 3500 years B.P. (W & S Consultants 1985:69, 1991; Whitley and Beaudry 1991; Whitley et al n.d.). This comprised the initial occupations of a series of what have been termed site complexes. These are agglomerations of small habitation and special purpose sites that are localized in relatively restricted areas (Whitley 1979a,1985; Whitley and Beaudry 1991), and are generally associated with springs or other permanent water sources. A series of site complexes have now been identified and studied in the Conejo Corridor region and, although the evidence is less complete for the Santa Clara Valley and the Simi Corridor, they are known to exist in these regions as well. For example, site complexes have been identified in Tierra Rejada and Happy Camp Canyon, in the Simi Corridor (W & S Consultants 1991 a), while a number are present in the Santa Clara Valley (W &S Consultants 1994c). However, most previous research has been conducted on the site complexes in the Conejo Corridor, with our understanding of this settlement type less well developed in the Simi Corridor and Santa Clara River Valley. Within the Conejo Corridor, each of these complexes contains deposits or components that represent the entire temporal span of inland occupation. As well, there is no clear functional or adaptational differentiation between earlier versus later temporal components of these complexes. That is, even while there is a general tendency 11 towards more complexity in the nature and variability of the tool assemblages towards the present, it is now clear that even some of the earlier temporal components in the region exhibit subsistence emphasizes found in the later components (W & S Consultants 1984). And this is to say that, from the initial occupation of this inland region, a very generalized foraging strategy was followed, not necessarily by every site complex in the area, but certainly by the inland occupation when considered as a whole (ibid; Whitley and Beaudry 1991). Thus, not only do we see early occupations exhibiting artifact assemblages that resemble more typically 'later' assemblages, with their heavy emphasis on hunting and hunting tools, but we also see late sites very much appearing like temporally 'earlier' sites, with a dominance of groundstone tools and chopping implements (ibid). The inference that results, consequently, is that the establishment of inland sites some 3500 years ago in inland Ventura County appears to represent an effort to exploit a variety of non - coastal environments, following a number of different subsistence strategies. This point of initial exploitation and occupation may correlate with a shift to the modern climatic regime, which also appears to occur at this time (G. Smith, personal communication, 1990). Regardless of cause, however, it is apparent that it was part of a far western North American -wide expansion in population and settlement (W & S Consultants 1993; see below). Further, it is clear that no single subsistence strategy uniquely characterized any specific time period; instead, a generalized foraging pattern appears to have held for the entirety of the prehistoric occupation of the inland area. Some differences have been noted between site complex distributions in the Conejo Corridor and the Santa Clara Valley. These have implications for the Simi Corridor generally, and the Moorpark region specifically. In the Conejo Corridor, site complex distributions are both relatively dense and surprisingly regularly spaced: generally, they are present every one to 1.5 km across the entire Conejo Corridor, apparently reflecting the widespread availability of potable water, and the high carrying capacity of the area. In the Santa Clara Valley below approximately Newhall, in contrast, site complexes are restricted to the banks of the river itself, and are tied to permanent streams flowing southwards out of the Los Padres Mountains (W &S Consultants 12 1994c). That is, they are much more widely- spaced, and are essentially absent in the foothills on the southern side of the valley, all reflecting the limited availability of water in this drier portion of inland coastal southern California. At a provisional level, we hypothesize that the Moorpark/Simi Valley region is transitional between the densely spaced complexes characteristic of the Conejo Corridor and the very widely spaced complexes of the Santa Clara Valley. This suggests that archaeological sites in the Moorpark area should be localized into relatively few areas, should show a strong association with natural water sources, and should represent relatively large concentrations of sites. This hypothesis has at least received a preliminary evaluation during previous work on the proposed Hidden Creek Ranch study area, which involved Phase I survey and the Phase II test excavation of six sites (W &S Consultants 1994a, 1995). The Phase I survey involved a review of existing records and an intensive on -foot study of the property. Two previously recorded prehistoric archaeological sites were identified during the background records search. In addition, 20 new prehistoric sites- were identified and recorded during the fieldwork within the proposed Hidden Creek Ranch. The resulting total of 22 sites, which include the ten considered in this study, are all concentrated in the southeastern portion of the study area, apparently as a result of the more favorable natural environmental conditions relative to the drier conditions on the remainder of the property. This concentration sites clearly represents a site complex and, thus, is analogous to similar concentrations of sites elsewhere in the Conejo and Simi Corridors (W &S Consultants 1994a). The preliminary evaluations of these 22 sites, based on original Phase I level impressions, suggested that 13, or 60 %, of them were lithic scatters /quarry workshops; that is, low density concentrations of stone tool manufacturing debris spread across the existing groundsurface. Another five of the sites (23 %) appeared to be primarily quarry workshops that were believed to possibly contain small associated midden deposits; that is, minor-subsurface archaeological deposits. These five sites were provisionally termed small campsites. The remaining four sites (18 %) appeared to have relatively large midden deposits surrounded by larger surface scatters of artifacts. These were preliminarily interpreted as seasonal villages, with the smaller 13 sites believed to have served as ancillary activity areas related to the occupation of these bigger sites. The previous test excavations on the Hidden Creek Ranch were conducted at six of these 22 sites in 1994: CA -VEN -508, -1132, -1133, -1134, -1135 and -1136 (W&S Consultants 1995). The Phase II fieldwork involved mapping, the surface collecting of groundsurface artifacts and archaeological indicators, and the hand excavation of test pits on each site, along with laboratory processing, cataloging and analyses of the recovered artifact collections. CA -VEN -508 was originally recorded in 1977. When fieldwork was conducted on this site in 1994, no artifacts or other archaeological remains could be relocated. CA -VEN- 508, accordingly, was interpreted to no longer be an extant archaeological resource (ibid). CA -VEN -1132 was found to comprise a small surface site during the 1994 Phase II testing. A complete surface collection of the archaeological remains present at this locale resulted in the recovery of only 12 artifacts. Formal worked artifacts were limited to core /cobble complex tools and groundstone implements. One of these, a pestle, indicates that the site was used sometime after 3500 years B.P. Given the ages assigned to other sites during the study, CA -VEN -1132 was interpreted to date to the Intermediate period, or between 3500 and 800 years B.P. CA -VEN -1132 apparently represents a small plant processing station, probably used as an ancillary activity area related to the occupation of nearby campsites (ibid). CA -VEN -1133 proved through testing to be solely a single, isolated piece of lithic debitage; no other artifacts or archaeological indicators were present at this locale. It is most likely that this isolated artifact was dropped during the period when the nearby campsites were inhabited. The existence of this site reflects the general intensity of use of the study area during this period (ibid). CA -VEN -1134 was found to consist of a small midden deposit buried by a lens of soil. The groundsurface on the site included artifacts dating to the later portion of the 14 Intermediate period, or from approximately A.D. 500 to 1200, therefore the midden deposit itself probably dates between 3500 and 1500 years B.P. Although lacking intact subsurface features, such as hearths, housepits or human burials, the presence of the midden deposit nonetheless indicates that CA -VEN -1134 served as a habitation site. Given the size and nature of the site and deposit, it is most likely that CA -VEN- 1134 was a small, dispersal phase campsite, seasonally occupied by a single extended family (ibid). CA- VEN -1135 was found to be a relatively large but low density midden deposit. Like nearby CA -VEN -1134, this site appears to have been occupied during the Intermediate period, or from about 3500 to 800 years B.P. Based on the recovered artifact assemblage, CA -VEN -1135 was interpreted as a seasonally occupied dispersal phase camp, again similar to nearby CA -VEN -1134. It is likely that these two camps where, in fact, portions of the same dispersal phase camp and that they were never occupied simultaneously; instead, their geographical proximity may reflect the fact that Native Californian campsites moved periodically within a relatively restricted area, as huts burnt down and so on (ibid). CA -VEN -1136 was found to be a small surface lithic scatter. A complete collection of the surface artifacts from this site yielded only seven specimens, all of which are made of quartzite. This site apparently served as a minor and casually -used quartzite quarry/workshop. Again, although no temporal diagnostics were found on this site, it is most likely that is was used at the same time as the nearby campsites, placing it in the Intermediate period (ibid). The previous Phase I survey and Phase II test excavations on the Hidden Creek Ranch study area, then, tended to confirm that site complexes are more widely spaced in the Simi Corridor than in the Conejo Corridor. They also demonstrated that the initial occupation of this portion of inland Ventura County also occurred during the Intermediate Period, or roughly 3500 years B.P. Finally, a notable aspect of the recovered archaeological record from the previous Phase II test was the absence of any significant evidence of Late Prehistoric (or post -800 years B.P.) occupation. At the time that the 1994 Phase II test was conducted it was uncertain whether the failure 15 to find such late dating prehistoric remains was a result of a diminution in population and /or abandonment of the inland area during the Late Prehistoric Period, or instead simply the result of the relatively small sample of sites that was investigated. That is, we did not know whether significant later occupation and use of this site complex had occurred, but simply was not reflected in the relatively small sample that we then had obtained. However, test excavations conducted at approximately the same time in the nearby Santa Clara River Valley found evidence supporting the view that the early Late Prehistoric Period was characterized by site abandonment and/or population decline (W &S Consultants 1994c). The 1997 Phase II test excavations at ten additional sites within the Hidden Creek Ranch study area was therefore directed partly towards resolving this problem. Specifically, we wished to determine whether there was in fact a population peak during the Intermediate Period following by an abandonment of sites and /or reduction of population during the early Late Prehistoric Period, as is suggested by the Santa Clara River Valley data. 16 CHAPTER 2 FIELD METHODS 2.1 Introduction Phase II archaeological fieldwork at sites CA -VEN -1130, -1137, -1138, -1139, -1140, - 1141, -1142, -1143, -1144 and -1147 was intended to establish the nature and significance of each site, and to thereby provide baseline data from which a determination of the ultimate disposition of these cultural resources could be made. This required the collection of a representative sample of artifacts and archaeological indicators from each of these ten cultural resources, the establishment of the vertical and horizontal boundaries of each cultural deposit, and an analysis of the recovered artifact assemblage from these archaeological localities. Procedures followed in the collection of data useful for establishing the nature and significance of the ten sites included mapping, surface collecting of artifacts lying on the groundsurface, and test excavation of pits to establish the presence or absence of a subsurface archaeological deposit, as well as to characterize such a deposit if found to be present on the sites considered in this study. Though these procedures were systematized so that the recovered data would be comparable between each site, as well as with previous studies in the region, the magnitude of effort varied somewhat between the sites, reflecting the field conditions specific to each locale. We discuss each of these field methods below, with details on the level of effort expended at each site provided in the subsequent chapter. 2.2 Surface Collection In order to determine the maximum areal extent of each site, the initial field procedure was to locate, map and collect all surface remains present on the groundsurface. In order to identify all such remains, the general area of each site was walked by crew - members spaced in approximate two meter intervals. Identified artifacts and 17 archaeological indicators were then marked with flagging tape. Surface remains found within an area of approximately 3 meters - square in size (i.e., within a circle with a one -meter radius) were treated as discrete artifact associations and collected as clusters. Transit, stadia and surveyor's chain were subsequently used to map all remains or clusters of remains, which were numbered and collected by these provenience points. 2.3 Test Excavations Employing an equivalent procedure used at all sites tested during this Phase II project, the number and location of the test pits placed on each site were predicated on an evaluation of the very localized geomorphological conditions found to be immediately present. Specifically, recognizing that subsurface archaeological remains could only be expected in areas where depositional processes contributed to the accumulation of soils, and that areas of active degradation would not only lack subsurface deposits but would also most likely contain surface finds (if found to be present) out of original context, test pits were placed in areas where the probability of deposition was deemed highest on each site, and subsequently located to delineate any such discovered deposits. In general, such depositional areas can be said to include: toeslopes and foots of hills; swales; and areas where active rodent activity or vegetative vigor indicate soil accumulation and depth. Conversely, areas of daylighting bedrock and erosional ridges, hilltops and slopes were conceded only a minimal amount of testing, because of the very limited likelihood that they could accumulate buried archaeological remains. Excavation units were 1x1 meter in size and were designated numerically at each site. Each unit was dug with pick, shovel and trowel in arbitrary ten centimeter spits or levels. Spoils from each of these levels was screened through one - eighth inch mesh. All artifacts and archaeological indicators were collected and bagged by unit level. In the initial units excavated on each site, excavation was continued for approximately 50 cm beyond the apparent termination of the cultural deposit, in order to obtain a clear indication of the soils stratigraphy present, or until bedrock was encountered. 18 Subsequent to stratigraphic definition and profiling, excavation was continued through two culturally sterile levels (i.e., 20 centimeters), or until decomposing bedrock was encountered. The combination of these procedures allowed for the definition of the size of the surface and subsurface components of each site (if found to be present). This also resulted in the recovery of a representative sample of artifacts from each locality, which allowed for an evaluation of the nature and significance of the remains. Finally, these procedures allowed us to evaluate the integrity of each of these ten cultural resources. w CHAPTER 3 FIELD RESULTS 3.1 Introduction Using the procedures outlined above, Phase II fieldwork at sites CA -VEN -1130, -1137, -1138, -1139, -1140, -1141, -1142, -1143, -1144 and -1147 resulted in the collection of a substantial quantity of archaeological remains, although the recovered remains were not uniformly distributed between the ten sites. In the next chapter we discuss the recovered archaeological remains from these sites in detail, including a summary of the laboratory procedures by which these collections were processed and analyzed, a review of each site's assemblage in typological terms, and an outline of certain of the analytical concerns and conclusions these collections allow us to draw. However, prior to considering the artifact collections in specific terms, below we present a summary of the field results in a more general sense, particularly with reference to the size of the surface manifestations of each site, the presence /absence of subsurface remains, the nature of the soils present, and what these attributes imply about each cultural resource. 3.2 CA -VEN -1130 3.21 Test Excavation Fourteen 1x1 meter test pits were dug at CA -VEN -1130, using the procedures outlined previously. These demonstrated that a relatively small midden deposit, measuring approximately 145 meters N -S by 45 meters E -W (or 6525 meters square) is present on the site, localized towards the northern end of the recorded site location (Figure 2). The soils on the site may be described as follows: A Horizon: Sandy silty loam midden that is (Munsell) Dark Grayish Brown 20 (10YR4/2) in color. This averages about 40 cm deep, and has been disturbed by rodents and cultivation (disking). It is artifact bearing and represents the archaeological deposit at CA -VEN -1130. B Horizon: A highly oxidized relict B Horizon (paleosol) was present in one pit (Unit #3) at 80 cm depth. This is Dark Yellowish Brown (Munsell 10 YR 4/6), and is culturally sterile. However, it is approximately 20% disturbed by rodent burrows, which have introduced some artifacts below 80 cm depth. C Horizon: The parent material for the soils on the site is an oxidized marine conglomerate bedrock (Yellowish Brown, 10 YR 5/4). Areas of thin soil on the site tend to contain a relatively thick lens ( >10 cm) of calcium carbonate immediately above this bedrock. With the exception of the localized conditions seen in Unit #3, soils on CA -VEN -1130 then exhibited the typical A/C horizonal relationship that is characteristic of the generally youthful soils in this region. The results of the excavation per each test unit may be summarized as follows: Unit # 1: Excavated to bedrock at 50 cm depth. Artifacts present to base. Unit #2: Excavated to bedrock at 40 cm; artifacts present in all levels. Unit #3: Excavated to bedrock at 100 cm. Artifacts restricted to A Horizon with maximum depth of 80 cm, with a few introduced in rodent krotovinas into the B Horizon. Unit #4: Dug to bedrock at 30 cm; artifacts restricted to top 20 cm. Unit #5: Dug to bedrock at 20 cm; culturally sterile. Unit #6: Excavated to bedrock at 30 cm; artifacts to base. Unit #7: Culturally sterile; dug to 30 cm. Unit #8: Dug to bedrock at 20 cm; culturally sterile. (Within an area of high bedrock at the crest of the knoll). Unit #9: Bedrock encountered at 30 cm; with the exception of a few introduced specimens, culturally sterile. 21 Unit #10: Bedrock encountered at 10 cm; culturally sterile. Unit #11: Dug to bedrock at 20 cm; culturally sterile. Unit #12: Bedrock at 20 cm; culturally sterile. Unit #13: Bedrock encountered at 10 cm; culturally sterile. Unit #14: Bedrock at 20 cm depth; culturally sterile. The archaeological deposit at CA -VEN -1130, then, was essentially concentrated in the northern portion of the site, within the areas of Units #1, 2, 3, 6 and 8. The surface lithic scatter (see below) was more extensive than the midden deposit (as is usually the case) but, based on the archaeological remains recovered from the top 10 to 20 cm in each unit -- much of which were introduced into the subsoil by disking -- drops off dramatically away from the midden proper. No intact subsurface features, such as hearths, housepits or human burials, were found during the test excavations. Although the archaeological deposit has suffered some degradation from rodent burrows and disking, it is essentially intact and in good condition. 3.22 Surface Collection Surface collection included the mapping and recovery of a small number of artifacts that were present on CA -VEN -1130. This was limited to seven artifacts. However, the overall dimensions of the original surface scatter at the site is improved by the addition of the information provided by the excavations of the test pits: the top 10 -20 cm of archaeological materials in these units are mixed into the groundsurface by disking and rodent activity, and thereby aid the determination of the overall original lithic scatter size. This indicates that the surface dimensions of the lithic scatter originally extended about 340 meters N -S by 90 meters E -W, for an overall area of 28,800 meters square. However, because this surface component of the site has been highly impacted by disking, the dimensions of the midden deposit provide the appropriate estimate for the extant, intact portion of the site. 22 3.3 CA -VEN -1137 3.31 Test Excavation Eight 1x1 meter test pits were dug on CA- VEN -1137 during the Phase II test (Figure 3). These demonstrated that a shallow midden deposit, averaging about 30 cm in depth, is present on this site. This measures about 65 meters N -S by 55 meters E -W, or 3575 meters square in size. Soil conditions at CA -VEN -1137 were found to be very similar to those found at CA- VEN -1130, discussed above, with one exception. Soil development at the site tended to be greater so that the archaeological deposit as a whole essentially overlay a culturally sterile, relict B Horizon paleosol. (An alternative way of looking at this is that bedrock was considerably deeper in the area of this site than was the case at the previous site). The presence of this widespread B Horizon underlying the midden deposit is important on two counts. First, it suggests that considerable stability has existed on this landform during the past, which has allowed this paleosol to form and be preserved. Second, we have generally found that this B Horizon is between 2000 and 4000 years old in Ventura County (W &S Consultants 1985). This would suggest that the archaeological midden deposit on the site is most likely less than 4000 years old. Soils may be more specifically described as follows: A Horizon: Sandy silty loam midden; Munsell Brown (10 YR 4/3) in color; generally about 30 cm thick. Rodent and disking have disturbed this horizon to some degree. B Horizorf: Highly oxidized relict B paleosol that is Munsell Yellowish Brown (10 YR 5/8). This averages 20 - 30 cm thick and is >10% disturbed by rodent krotovinas. C Horizon: Oxidized marine conglomerate bedrock ( Munsell Yellowish Brown, 23 10 YR 5/4). The testing results at CA -VEN -1137 may be summarized as follows, by excavation unit: Unit # 1: Dug to 20 cm, in B Horizon; culturally sterile. Unit # 2: Excavated to sterile B Horizon at 20 cm; artifacts present through A Horizon. Unit # : Dug to B Horizon encountered at 20 cm; artifacts to base of A Horizon. Unit # 4: Sterile B Horizon encountered at 30 cm; artifacts found throughout A Horizon. Unit # : Bedrock encountered at 30 cm; artifacts present to bedrock (no B Horizon present). Unit # : Excavated to sterile B Horizon encountered at 50 cm; artifacts present throughout the A Horizon. Unit # 7: Dug to sterile B Horizon encountered at 30 cm; artifacts present throughout A Horizon. Unit # : Dug to culturally sterile B Horizon encountered at 20 cm; artifacts limited to introduced materials (i.e., culturally sterile). The archaeological midden deposit at CA -VEN -1137, then, is a relatively thin layer of A Horizon soil that overlies a culturally sterile relict B soil. No intact cultural features, such as hearths, housepits or human burials, were discovered in the midden deposit. It none the less appears intact and maintains integrity. 3.32 Surface Collection The surface collection at CA -VEN -1137 resulted in the recovery of a small sample of artifacts, consisting of three lithic tools. Combined with the surficial data obtained from the test pits, the overall size of the surface component of the site is about 112 meters N -S by 32 meters, or 3360 square meters overall. 24 3.4 CA -VEN -1138 3.41 Test Excavation Twelve excavation units were dug on site CA -VEN -1138 (Figure 4). As at the two previous sites, these revealed the presence of a shallow midden deposit that measures about 60 meters N -S by 100 meters E -W, covering 6000 square meters overall. The depth of this midden averaged about 20 cm. Soils at the site may be described as follows: A Horizon: Sandy silty loam midden that is Munsell Brown (10 YR 4/3), and is artifact bearing. This averages about 20 cm thick and has been disturbed by rodents and cultivation. B Horizon: Highly oxidized relict paleosol; Munsell Yellowish Brown ((10 YR 5/8); culturally sterile. This is >10% disturbed by rodent krotovinas. Horizon: Oxidized marine conglomerate bedrock (Munsell Yellowish Brown, 10 YR 5/4). A thick calcium carbonate layer (approximately 10 cm thick) was present in the one pit (Unit #3) where high bedrock was exposed. As at CA -VEN -1137, the thin midden deposit present at this site overlies a culturally sterile B Horizon paleosol. Again, this paleosol is an indicator of geomorphic stability, and puts a maximum limit on the age of the archaeological deposit, which is roughly 4000 years. Results from the excavation of the test units may be summarized as follows: Unit #1: Unit #1 was dug to 40 cm depth, where the culturally sterile B Horizon was encountered. Artifacts were present throughout the A Horizon soil overlying this paleosol. 25 Unit #2: Dug to 20 cm, culturally sterile B Horizon. Unit was outside midden deposit. Unit #3: Dug to bedrock at 30 cm. Artifacts present to bedrock. (No B Horizon in this unit). Unit #4: Dug to B Horizon at 20 cm; no artifacts. Unit #5: B Horizon encountered at 20 cm; unit culturally sterile. Unit #6: Dug to sterile B Horizon, encountered at 10 cm; no artifacts. Unit #7: Dug to sterile B Horizon, encountered at 10 cm; no artifacts. Unit #8: Dug to sterile B Horizon at 30 cm; artifacts present throughout A Horizon. Unit #9: Excavated to sterile B Horizon at 20 cm; no artifacts. Unit #10: Dug to sterile B Horizon encountered at 10 cm; no artifacts. ni #11: Sterile B Horizon encountered at 10 cm; no artifacts. Unit #12: Dug to 20 cm, the depth of the sterile B Horizon; no subsurface artifacts. As should then be clear, the midden deposit at CA -VEN -1138 is a very thin and relatively restricted deposit that overlies a relict B paleosol. This, again, is an indicator of stability and a limiter in terms of overall site age. No archaeological features, such as hearths or housepits, were identified during the test. The deposit appeared to maintain integrity and to be in relatively good condition, however, even though it has suffered some impacts from disking and rodents. 3.42 Surface Collection A total of 20 archaeological specimens were recovered from the groundsurface at CA- VEN -1138. These were found within an area that is only slightly larger than the size of the extant midden deposit, per se, measuring about 125 meters N -S by 95 meters E- W, or 11,875 meters square. 26 3.5 CA -VEN -1139 3.51 Test Excavation Four 1x1 meter test pits were excavated at CA -VEN -1139. No subsurface archaeological remains were found at this locale, indicating that it is a surface lithic scatter. Soils at the site may be described as follows: A Horizon: Sandy loam with cobbles; Munsell Brown (10 YR 5/3); average thickness about 10 cm. Culturally sterile. B Horizon: None present. C Horizon: Oxidized marine conglomerate bedrock; Munsell Yellowish Brown (10 YR 5/4). The soils, in other words, are very shallow with high bedrock, and are undeveloped and probably relatively youthful. Results for the excavation units are as follows: Unit #1: Dug to bedrock at 10 cm; culturally sterile. Unit #2: Bedrock encountered at 20 cm; culturally sterile. Unit #3: Bedrock at 10 cm; sterile. Unit #4: Bedrock encountered at 10 cm; culturally sterile. As should be clear, soil conditions make it extremely unlikely that a subsurface deposit would be present at this location, and none was found during the testing. 27 3.52 Surface Collection Surface collecting at CA -VEN -1139 resulted in the recovery of the only extant archaeological remain at this site, a single lithic artifact, reflecting the origin of the site as the expression of a single incident of prehistoric human activity. 3.6 CA -VEN -1140 3.61 Test Excavation Twelve 1 x1 meter pits were dug at CA -VEN -1140 (Figure 6). These revealed the presence of a small midden deposit that measures about 130 meters SW -NE by 60 meters NW -SE, or 7800 meters square. This midden is relatively deep, when compared to other sites investigated during this project, averaging about 45 cm' thick. In general terms the soils at the site may be described as follows: A Horizon: Sandy silty loam midden; Munsell Dark Grayish Brown (10 YR 4/2) in color. This averages about 45 cm deep, and has suffered from some rodent and cultivation (disking) disturbance. It is artifact bearing. B Horizon: A highly oxidized relict B Horizon (paleosol) that is Dark Yellowish Brown (Munsell 10 YR 4/6); culturally sterile; with >10% disturbance by rodent burrows. Average thickness, 20 - 30 cm. C Horizon: Oxidized marine conglomerate bedrock (Munsell Yellowish Brown, 10 YR 5/4). Calcium carbonate layer present immediately above bedrock at 90 cm in Unit #2. As with the other sites that proved to contain intact middens in the project area, the soils at CA -VEN -1140 consist of a midden overlying a culturally sterile B Horizon paleosol. This again indicates geomorphic stability and limits the age of the deposit to roughly 4000 years maximum. The results of the testing, by unit, are summarized below: Unit #1: Dug to culturally sterile B Horizon, encountered at 40 cm. Sterile. Unit #2: Excavated to bedrock at 90 cm (no B Horizon); artifacts present throughout the A Horizon (to 90 cm). Unit #3 Dug to bedrock at 70 cm (no B Horizon); artifacts present to bedrock. Unit #4: Dug to sterile B Horizon at 40 cm. Small amount of cultural material to 30 cm depth. Unit #5: Excavated to sterile B Horizon at 50 cm; artifacts present throughout A Horizon. Unit #6: Dug to bedrock at 30 cm (no B Horizon); artifacts present to base. Unit #7: Dug to sterile B Horizon at 20 cm; culturally sterile. Unit #8: Excavated to sterile B Horizon at 20 cm; culturally sterile. Unit #9: Dug to sterile B Horizon at 40 cm; artifacts present throughout A Horizon. Unit #10: Dug to 50 cm depth of sterile B Horizon; artifacts present throughout the A Horizon. Unit #11: Dug to bedrock at 40 cm; no B Horizon; small amount of cultural material (introduced by rodent burrows) to 30 cm. Unit #12: Excavated to 40 cm bedrock; no B Horizon; artifacts to base. CA -VEN -1140 can be interpreted as a location with highly undulating bedrock which has been very stable for 4000 or more years ago. When occupied aboriginally, daylighting bedrock was exposed in some locations. The midden deposit, which overlies an older paleosol, built up around these bedrock outcrops, which are now covered with modern topsoil. No subsurface archaeological features, such as hearths, human burials or housepits, were found at the site. It has suffered some disturbance, the most significant of which is a graded dirt road, which runs along the approximate eastern side of the site. This has removed roughly 15% of the archaeological deposit; the remainder, however, is 29 intact and maintains integrity, even though it has suffered from cultivation and rodent activities. 3.62 Surface Collection Surface collection at CA -VEN -1140 yielded nineteen artifacts, almost all of which were collected within the midden area proper. Overall size of the original surface component of the site, however, is about 165 meters N -S by 125 meters E -W, or 20,625 meters square. 3.7 CA -VEN -1141 3.71 Test Excavation Test excavations at CA -VEN -1141 resulted in the completion of eight 1x1 meter pits (Figure 7). None of these contained subsurface archaeological remains, with the exception of a few specimens introduced into the plow zone of the soil by disking. This indicates that this site is a surface lithic scatter that has suffered some adverse impacts due to cultivation and rodent activities. Soils at the site, accordingly, were similar to those encountered at CA -VEN -1139, another surface scatter. They may be described as follows: A Horizon: Sandy loam with cobbles; Munsell Brown (10 YR 5/3); average thickness about 10 cm. Culturally sterile. B Horizon: None present. C Horizon: Oxidized marine conglomerate bedrock; Munsell Yellowish Brown (10 YR 5/4). 30 The results of the subsurface testing may be summarized, by unit, as follows: Unit #1: Dug to bedrock at 10 cm; culturally sterile. Unit #2: Dug to bedrock at 10 cm; culturally sterile. Unit #3: Dug to bedrock at 20 cm; culturally sterile. Unit #4: Dug to bedrock at 20 cm; culturally sterile. Unit #5: Dug to bedrock at 10 cm; culturally sterile. Unit #6: Dug to bedrock at 10 cm; culturally sterile. Unit #7: Dug to bedrock at 10 cm; culturally sterile. Unit #8: Dug to bedrock at 10 cm; culturally sterile. A thin layer of calcium carbonate was found overlying bedrock in Unit #3; otherwise, this was absent in the other units. Note also that a small quantity of lithic specimens were found in Units #2, 4 and 8, as implied above. All of these were within the plow zone and are best interpreted as surface materials introduced into the deposit. CA- VEN -1141, then, appears to be a surface lithic scatter associated with a surficial outcrop of cobbles. 3.72 Surface Collection Three lithic artifacts were surface collected at CA -VEN -1141. Combined with the specimens recovered from the first few centimeters of certain of the test pits, these indicate that the overall area of the site was originally about 110 meters in diameter, or 12,100 meters square. 3.8 CA -VEN -1142 3.81 Test Excavation Three 1 x1 meter test pits were excavated on CA -VEN -1142. None of these proved to contain subsurface artifacts of any kind, indicating that this site is a surface lithic 31 scatter. Soils on the site were identical to those found on CA -VEN -1141 discussed above, reflecting the fact that both sites are quarry/workshops associated with an lag outcrop of natural cobbles. The soils at CA -VEN -1142, accordingly, may be described as follows: A Horizon: Sandy loam with cobbles; Munsell Brown (10 YR 5/3); average thickness about 10 cm. Culturally sterile. B Horizon: None present. C Horizon: Oxidized marine conglomerate bedrock; Munsell Yellowish Brown (10 YR 5/4). Results of the test excavation are summarized by unit below: Unit #1: This pit was dug to bedrock which was encountered at 10 cm. The pit was culturally sterile. Unit #2: Dug to bedrock at 10 cm; culturally sterile. Unit #3: Also dug to bedrock at 10 cm and culturally sterile. 3.82 Surface Collection Six surface artifacts were recovered from the groundsurface of the site during the surface collection and mapping. These were found within a zone approximately 65 meters in diameter, representing an area of 4225 square meters overall. 3.9 CA -VEN -1143 3.91 Test Excavation Ten pits were dug on CA -VEN -1143 (Figure 9). These revealed the presence of a 32 small and shallow midden deposit, averaging about 25 cm in depth, that measured 60 meters N -S by 35 meters E -W. This represents an overall area of 2100 meters square. The soils at the site may be described as follows: A Horizon: Sandy silty loam midden; Munsell Dark Grayish Brown (10 YR 5/4); average thickness about 25 cm; artifact bearing. B Horizon: None present. C Horizon: Oxidized marine conglomerate bedrock; Munsell Yellowish Brown (10 YR 5/4). In this case a soil profile exhibiting an A/C (topsoi Vbed rock) contact was present at the site. This is common in southern California where the absence of water makes the soil- forming processes fairly slow, and where the soils themselves are often very youthful. The fact that the midden deposit is located in an A Horizon, in other words, makes it unlikely that the deposit is greater than roughly 4000 years old. Test results are best summarized by unit, as outlined below. Note that, at this site, all units were dug to bedrock, in part reflecting the very shallow soil build -up at this location. Unit #1: Dug to bedrock at 40 cm. Small number of artifacts restricted to plow zone and therefore introduced. Unit #2: Bedrock encountered at 60 cm; artifacts present to this depth. Unit #3: Dug to bedrock at 20 cm; culturally sterile. Unit #4: Excavated to 20 cm contact with bedrock; culturally sterile. Unit #5: Bedrock encountered at 20 cm; culturally sterile. Unit #6: Bedrock at 30 cm; culturally sterile. Unit #7: Dug to bedrock at 30 cm; culturally sterile. Unit #8: Bedrock encountered at 40 cm; artifacts present to 30 cm. Unit #9: Dug to bedrock at 30 cm; very small number of artifacts introduced by 33 rodents and disking (therefore subsurface culturally sterile). Unit #10: Dug to bedrock at 30 cm; artifacts to 20 cm. No subsurface features of any kind were found at CA -VEN -1143. Nonetheless, it is intact and in good condition, with previous impacts resulting primarily from cultivation and rodent activities. 3.92 Surface Collection Seven surface artifacts were recovered at CA -VEN -1143, which were augmented by the archaeological specimens collected from the top few centimeters of the excavation, within the plow zone. As is typically the case, the distribution of surface artifacts covered a larger area than the subsurface midden deposit. The surface scatter on the site extended about 95 meters N -S by 60 meters E -W for 5700 meters square. 3.100 CA -VEN -1144 3.101 Test Excavation Three 1x1 meter test pits were excavated at CA -VEN -1144 (Figure 10). With the exception of a couple of specimens recovered from the plow zone, no subsurface artifacts were recovered at this site, indicating that the extant portions of it represent a surface lithic scatter. However, unlike some of the other surface lithic scatters investigated during this project, it appears that a subsurface deposit may once have been present at this locale, inasmuch as over approximately 80% of the probable original site area has been graded away by an oil well pad. Thus, when examined during this Phase II study (and when originally recorded in 1994), CA -VEN -1144 had already been very heavily disturbed. The soils from the site may be described as follows: 34 A Horizon: Sandy loam with cobbles; Munsell Brown (10 YR 5/3); average thickness about 20 cm; culturally sterile. B Horizon: Highly oxidized relict B paleosol; Munsell Dark Yellowish Brown (10 YR 4/6); sterile. C Horizon: Oxidized marine conglomerate bedrock; Munsell Yellowish Brown (10 YR 5/4). The results of the test excavation are summarized by test pit below: Unit #1: Dug to culturally sterile B Horizon, encountered at 20 cm; culturally sterile. Unit #2: Dug to bedrock at 30 cm; culturally sterile. Unit #3: Dug to bedrock at 40 cm; culturally sterile. Although there may once have been a subsurface archaeological deposit at CA -VEN- 1144, by the time of our 1997 fieldwork this had been destroyed. Thus, this site lacked integrity, and thereby can be considered in extremely poor condition. 3.102 Surface Collection The destruction which has degraded the possible subsurface deposit at this site also severely impacted the surface component of it. Five specimens were recovered on the groundsurface of the site, in addition to four that came from the plow zone within Unit #2. These fall within an area approximately 100 meters in diameter, or 10,000 meters square. 35 3.110 CA -VEN -1147 3.111 Test Excavation Four 1x1 meter pits were excavated on the final site investigated during the 1997 Phase II test, CA -VEN -1147. No subsurface remains of any kinds were found in these subsurface pits, indicating that this site is a surface lithic scatter. The soils from the site may be described as outlined below: A Horizon: Sandy loam with cobbles; Munsell Brown (10 YR 5/3); average thickness about 10 cm. Culturally sterile. B Horizon: None present. C Horizon: Oxidized marine conglomerate bedrock; Munsell Yellowish Brown (10 YR 5/4). All four units placed on the site were excavated to bedrock, which was uniformly encountered at approximately 10 cm below the groundsurface. All of the units were culturally sterile. 3.112 Surface Collection Only a single archaeological specimen, a lithic flake, was found on CA -VEN -1147, thus providing a parallel with CA -VEN -1139, both of which represent single incidents of prehistoric behavior. 3.120 Summary In summary, the 1997 Phase II testing program within the Hidden Creek Ranch study 36 area found that five of the ten sites contained extant midden deposits, all of which are fairly shallow and small. These sites are CA -VEN -1130, 1137, -1138, -1140 and - 1143. The remaining five sites proved to be surface lithic scatters. These sites are CA -VEN -1139, -1141, -1142, -1144 and -1147. Two of these sites (CA -VEN -1139 and -1147) proved to contain only a single artifact; a third (CA -VEN -1144) had effectively been destroyed prior to our fieldwork. All extant artifacts were recovered from the remaining two sites during the surface collection. 37 CHAPTER 4 ARTIFACT ASSEMBLAGE AND ANALYTICAL CONCERNS 4.1 Introduction Although the general patterns of artifact distributions, enumerated in the previous chapter, provide important information relative to the size and nature of the ten archaeological sites considered in this Phase II study, proper determination of the significance and scientific importance of these resources can only be obtained with a more intensive analysis of the recovered artifact assemblages. Accordingly, in this chapter we consider these assemblages in some analytical detail, and what they imply about each of the sites as well as aspects of the prehistory of the region. We begin by detailing the laboratory procedures followed in the processing and curation of the recovered remains. Subsequently we outline the taxonomic system employed to categorize and classify each site's collection. This is followed by a typological summary of the artifacts and archaeological indicators recovered from each site. Finally, we consider the scientific importance of these remains in slightly larger comparative terms. This places them in a regional perspective, informs an understanding of their probable functions and chronological positions, and allows us to address the cultural historical problem identified at the outset concerning the relationship of the Intermediate to Late Prehistoric Period occupations. 4.2 Laboratory Procedures Following the completion of the Phase II fieldwork at CA -VEN -1130, -1137, -1138, - 1139, -1140, -1141, -1142, -1143, -1144 and -1147, the recovered artifact assemblages were taken to the W & S Consultants' laboratory for washing, processing and analysis. After each specimen was washed and labeled, metrical and typological analyses were performed. We provide measurements and weights for the various artifacts and archaeological indicators in the respective site catalogs included in this report. In order to facilitate typological comparisons between these ten sites, as well 38 as to other similar sites from this same region, we have employed a standardized taxonomic system. We describe this classificatory system in some detail below. 4.21 Taxonomic Considerations In considering the artifacts recovered from the Phase II investigations at CA -VEN- 1130, -1137, -1138, -1139, -1140, -1141, -1142, -1143, -1144 and -1147, we employ a morphological stone tool typology first published by Whitley et al (1979) and now widely used in the region. This affords a number of advantages. First, because of its widespread use (e.g., Johnson 1979; W & S Consultants 1984, 1989a, 1989b) it permits easy comparability between existing studies, including with the previous study of sites within the Hidden Creek Ranch study area (W &S Consultants 1995). Second, because it is morphologically rather than functionally based, it provides greater objectivity in taxonomic assignments. Specifically, it avoids the dangers inherent in inferring dubious functional purposes for stone tools that may have had multiple uses, and that often exhibit little in the way of formal attributes. In the inland southern California region, in particular, it is increasingly clear that most sites are characterized by expedient or casual tool assemblages, probably reflecting the fact that the sites resulted from dispersal phase activities that little emphasized formal patterns of behavior (W & S Consultants 1989b). Thus, a typology based on the elucidation of tool manufacturing stages, rather than one assuming final function of the implements, stands less chance of leading interpretations astray. However, this is not to imply that functional interpretations are unwarranted or undesired. Such is not the case; instead, it is simply to emphasize that functional interpretations must be made somewhat independent of - and therefore including other lines of evidence from - the typological assignments alone. The morphological typology employed here is based on four major categories of stone artifacts (cf. Whitley et al 1979). These are: (i) groundstone implements; (ii) core /cobble tools; (iii) flaked stone tools; and (iv) tool manufacturing waste, or debitage. Groundstone implements are tools that have been pecked and/or ground into shape. They include manos (or mullers) and metates (or basal grinding slabs), 39 along with mortars, pestles, stone bowls and comals (or griddles). Although there is a general association between groundstone artifacts and plant grinding, pulping and processing, as in the case of manos, metates, mortars and pestles, this is not invariably so: stone bowls and comals, for example, had other uses, with certain kinds of bowls, in particular, sometimes reserved for ceremonial purposes. Groundstone artifacts are usually (but not invariably) made of softer lithic materials. Metates, for example, are often made from sandstone or some other sedimentary material; bowls and comals are typically manufactured from steatite (soapstone or talc schist). Manos, however, were often derived directly from river cobbles of appropriate size, so that quartzite is a common material source. Core /cobble tools are generally large, bulky implements made by the reuse and/or modification of a river cobbles and lithic cores. They include 'hammerstones', 'choppers' and 'scraper planes'. Hammerstones are usually unshaped or minimally shaped, roughly fist - sized, stones that exhibit characteristic battering and pounding scars, but often otherwise lack modification. Choppers are cobbles or cores that have been unifacially or bifacially flaked to create a relatively sharp edge. Scraper planes are high- backed, unifacially flaked tools that are usually 'biscuit- shaped' in plan, with edge angles near perpendicular, and with heavy use -scars along their convex face. All of these tools were apparently employed for heavy pounding, scraping and /or battering tasks. There is a frequent association of core /cobble tools with groundstone artifacts (specifically manos and metates) in the nearby Conejo Corridor region (Whitley 1979b), suggesting that the two categories may have been functionally related; that is, that core /cobble tools may have served as part of a plant acquisition and processing toolkit. This is supported in reference to the scraper planes, in particular, which are argued to represent special yucca processing tools (Kowta 1969; Sails 1985). Further, this suggests in turn that the core /cobble tools were part of a woman's plant gathering toolkit (W & S Consultants 1989b). Flaked or chipped stone tools are secondary reductions from cores and cobbles. That is, they represent tools manufactured from flakes struck -off the primary sources of lithic 40 materials. These flakes may be used without modification as 'utilized flakes'; they may be bifacially flaked; or they may be unifacially flaked. It is apparent that the majority of the flaked or chipped stone tools in the region are either utilized flakes with no modification, or have edges that have been flaked unifacially or bifacially, but exhibit little or no effort for further edge modification or shape regularization (W & S Consultants 1989b). Again, this further emphasizes the casual or expedient nature of these tools, and also implies that they may have been used for a variety of tasks with little functional specialization. Correspondingly, the majority of the chipped stone tools from this region are what we have defined as biface or uniface 'edges', and they may have been used for any number of general cutting, scraping and abrading tasks. Of course, occasional projectile points and drills represent special types of bifaces with specific and known functions, whereas biface 'knives' (large leaf or knife - shaped tools) are presumed to have been used for cutting and piercing/stabbing tasks. Generally, chipped stone tools were made from material with particular flaking characteristics; specifically, those subject to conchoidal fracture. Crypto - crystallates such as chert and chalcedony, therefore, are common raw materials, but fused shale, quartzite, cherty- siltstone, rhyolite, andesite, basalt and occasionally obsidian may also be present in a collection. Because small hand specimens of rhyolite, andesite and basalt are, in fact, only distinguishable with petrographic analysis, we treat them all as "metavolcanics". And, as we have recently discovered (W & S Consultants 1991b), 'fused sandstone", resulting from contact metamorphism between Miocene Conejo Volcanics and sedimentary beds, was also a lithic material of common use in the region. Because of its similarities to fused shale (based, of course, on similar metamorphic origins), it has often been mistaken for this latter material. This would be inconsequential, save for the assumption that the putative fused shale has its sole origins in Grimes and Happy Camp Canyons, north of Moorpark and immediately adjacent to the current project area. Instead, it is apparent that a number of fused sandstone quarries are present in the nearby Conejo Corridor; that their respective lithic materials are widely misidentified as fused shale; and that, therefore, lithic exploitation was arobably much more widely ranging than the often inferred simple 41 exploitation of major quarries at Grimes Canyon might suggest (W & S Consultants 1991 b). The final category of stone artifacts is what can be considered lithic waste or debitage. It includes spent cores, waste flakes, and angular shatter. There are a number of different kinds of cores and flakes, and the presence of these varieties at a site tends to signify different types of tool reduction or manufacturing techniques. For example, the presence of large numbers of secondary and tertiary flakes usually indicates that chipped stone tool manufacture occurred at a locale, whereas primary flakes alone might be associated with the making of the cruder chipped stone tools, or might be expected at quarries where only the preliminary stages of tool manufacturing were conducted. Similarly, relatively large proportions of tertiary flakes correlate with habitation /campsites, in that tool maintenance and finishing occurred at these locales. Furthermore, because different lithic materials tend to correlate with different categories of tools, the material present in the debitage collection can also be a clue to a site's function. Quartzite and other 'crude' lithic materials, for example, are often found where core /cobble tools are manufactured, whereas crypto - crystallates tend to occur where chipped stone tools are manufactured. And, in a general way, there is an association between these last materials, chipped stone artifacts, and habitation sites (W & S Consultants 1989c). In addition to the lithic tool typology, other classes of artifacts may be present at local sites. Dietary remains, in the form of shellfish and faunal bones, are sometimes present, as are ornaments, usually in the form of shell beads. Where appropriate, based on the specifics of each recovered artifact assemblage, we consider these categories of remains below, on a site by site basis, as well. 4.3 Artifact Assemblage: CA -VEN -1130 The prehistoric artifact assemblage from CA -VEN -1130 consisted of 658 archaeological specimens (Table 1). These included 11 formal, worked stone tools (Table 2), 642 pieces of lithic debitage (Table 3), four fragments of faunal remains 42 (Table 4), and one miscellaneous artifact. We discuss each of these artifact classes in turn. 4.31 Lithic Tools and Debitage Lithic tools from CA -VEN -1130 include core /cobble complex, groundstone and flaked stone implements (Table 2). Flaked stone tools predominated, with six (or 55 %) of these worked implements recovered. Core /cobble complex tools were next most common: four, or 36 %, of these were collected. Only a single groundstone implement (9 %) was found on the site. . - .. Core /cobble complex tools from CA -VEN -1130 included three hammerstones and one chopper. Two of the hammerstones are Type 3, irregular core hammers (Whitley et al 1979:18). Both are made of quartzite. The other hammerstones is metavolcanic and is a Type 2A minimally modified hammer (ibid). The chopper is made of quartzite and is a Type 1 A uniface cobble chopper (ibid:12). Groundstone Artifacts Groundstone artifacts from CA -VEN -1130 were limited to a single specimen: a sandstone mano. It is a Type 213, shaped, domed uniface mano (ibid:38). Flaked Stone Tools Flaked stone tools were the most common component of the formal lithic tools from the site. They included two unifaces, two bifaces and two projectile points. Both of the unifaces are made of quartzite and are relatively large: although made on primary flakes, in size and probably in function they are equivalent to a uniface chopper. The bifaces are both made of fused shale; one is a crude base and the other is a fragment of an edge. Both can be considered "casual tools" in the sense of showing little shaping or finish working. 43 Two projectile point fragments were also recovered from CA -VEN -1130. One is made of chert and is the midsection of an atlatl dart point (Figure 12), judging from the width, thickness and fineness of working. This atlatl point fragment presumably predates A.D. 500. The other point is made of fused shale and corresponds to a relatively large Rose Spring Corner Notched arrow point type. These date between A.D. 500 and 1200. Both points are Intermediate Period in age, with the Rose Spring indicating a use of the site during the latter part of the Intermediate Period. The debitage from CA -VEN -1130 is summarized in Table 3. A total of 642 pieces of debitage was recovered from the site. Four types of lithic material were identified in this debitage assemblage: fused shale /sandstone; chert/chalcedony; quartzite; and metavolcanic (rhyolite, andesite, basalt). By lithic type, fused shale was by far the most common: 396 pieces of this stone, or 61.7 %, were recovered. This was followed by chert, 112 or 17.5 %; quartzite, 82 or 12.8 %; and metavolcanic, 52 or 8.1%. All of these lithic materials are locally available, with fused shale present in nearby Happy Camp Canyon and the other materials found in the immediate vicinity of the site. When the debitage assemblage is considered by flake type, tertiary flakes are by far the most common, constituting 435 examples, for 68.8% of the assemblage. These resulted from final tool finishing and maintenance. They are usually associated with habitation sites, where such activities occurred. The importance of fused shale in the debitage assemblage is further emphasized in the tertiary flakes: 312 of the 435 flakes of this type (72 %) are fused shale; these represent fully 48.6% of the debitage assemblage as a whole. Tertiary flakes are followed, in order of importance, by angular shatter, 118 or 18.4 %; primary flakes, 52 or 8.1 %; and secondary flakes, 37 or 5.8 %. The majority of the primary flakes are quartzite (30 of 52, or 57.7 %), a lithic material particularly suited for heavy tasks to which primary flakes may be directed. 44 4.32 Faunal Remains In addition to the lithic and bone artifacts, 1.7 gms of faunal remains were also recovered from CA -VEN -1130. Animal bone from the site is summarized in Table 4. In interpreting such a collection of faunal remains from local archaeological sites, an important analytical concern is the taphonomic history of the collection. That is, because bones may occur naturally in the subsoil - especially bones of small mammals such as pocket gophers and ground squirrels that commonly reside and die in burrows - it is not always a straightforward process to determine which specimens in a faunal collection are truly archaeological and which are present as the result of normal animal activities. This problem is compounded by the fact that certain of these same burrowing animals may have been employed as parts of the prehistoric aboriginal diet. Furthermore, domestic dogs and wild coyotes may take or leave bones on sites, while large mammals can die on them after their prehistoric occupation. And, in the case of caves and rockshelters, a very wide range of animals may have lived and died in these sheltered habitats, or have been dropped there by other non -human predators. Because of these confounding factors we have developed a series of short and general guidelines to aid in determining which specimens are most likely 'cultural', in the sense of having resulted from aboriginal behavior, and which bones are most probably unrelated to the archaeological remains and therefore only within the archaeological deposit due to serendipitous circumstances. In terms of positively determining that a given bone was brought onto a site by human agency we consider the following as useful criteria: (i) butchering and cutting marks; (ii) evidence of burning and charring; (iii) knowledge of the habits of a given species, indicating a low probability of its remains being naturally interred in a particular type of deposit; and (iv) ethnographic information concerning the diet and butchering habits of local aboriginal groups. Information counting against the inclusion of a given bone in a reconstruction of prehistoric diet includes: (a) knowledge concerning the behavior of a given species, 45 indicating a high likelihood of natural deposition in the type of deposit in question; (b) 'freshness' of the bone; (c) absence of butchering marks and burning, or the presence of modern saw -cut marks; and (d) ethnographic data discounting the use of that species by local groups. Thus, a cut long bone of a deer or a charred rabbit femur both would be considered most probably as 'cultural' specimens, and of course any marine mammal or fish bones could only have been deposited in an archaeological deposit by human activities. By contrast, pocket gopher and ground squirrel bones would be considered with suspicion if derived from an open -air deposit, such as CA -VEN -1130, particularly if they lacked any evidence of butchering or charring. With these considerations in mind, the small collection of faunal remains from CA- VEN -1130 was analyzed and is tabulated in Table 4. As is typical in sites in the region (cf. Reynolds 1978), this collection consists of very small fragments, resulting from a heavy processing of the bones (probably by breaking and smashing) to extract the marrow. The result is a collection that is very difficult, if not essentially impossible, to speciate, especially since there are few articulations upon which to base a positive species identification. Consequently, we have organized the specimens, as well as those from the other sites considered in this study, into a series of size categories that provide some idea of the probable species (or range of species) from which they were derived. Except in cases in which the bone is so fragmentary so as to preclude any categorization whatsoever, unspeciated bone has been assigned to the appropriate size grouping; where possible, the skeletal element has been identified as well. These categories, with the range of species potentially observable in southern California sites along with certain of their live weights (cf. Reynolds 1978), are as follows: Small mammal: Pocket gopher (2.5 - 8.8 ozs) Kangaroo rat (1.6 - 2.7 ozs) Harvest mouse (0.3 - 0.6 ozs) Dusky- footed woodrat (8 - 13.75 ozs) 46 Meadow mouse (1.5 - 3.5 ozs) Audubon cottontail (912 gms) Brush rabbit (1.25 - 1.8 lbs) Ground squirrel (0.2 - 0.5 lbs) Western gray squirrel (average = 1.75 lbs) Medium mammal: Black- tailed hare (4.4 - 6.1 lbs) Grey fox (7 -13 lbs) Coyote (20 - 50 lbs) Domestic dog Raccoon (1.8 - 22.2 kg) Badger (3.6 - 10 kg) Striped skunk (6 - 14 lbs) Bobcat (15 - 35 lbs) Large mammal: Mule deer (125 - 200 lbs) Guadalupe fur seal (50 - 100 lbs) California sea lion (males to 600 lbs, females to 400 lbs) Grey wolf (60 - 100 lbs) Horse Domestic sheep Domestic cow We emphasize, again, the relatively high degree of processing that the small collection of faunal remains from CA -VEN -1130 exhibits. With the above difficulties and caveats in mind, it can then be reported that four pieces of animal bone were recovered from the site, representing a total of 1.7 gms. Two of these, weighing a total of 1.1 gms, were large mammal in size. The other two weighed 0.6 gms and are both small mammal sized specimens. The faunal analysis suggests the following points. First, and perhaps most importantly, the presence of a more substantial quantity of faunal remains from nearby site CA- VEN -1135 demonstrates that local soils allow for the preservation of osteological 47 remains within the Hidden Creek Ranch area (W &S Consultants 1995). The limited quantity of fauna from CA -VEN -1130, then, can be understood as the result of prehistoric behavioral patterns rather than site preservational problems. With respect to CA -VEN -1130, per se and second, this collection demonstrates that animal protein was a minimal component of the prehistoric diet. Though present, this animal bone collection is in fact extremely small relative to other sites of similar age in the inland Ventura County region. For example, a quick comparison of the relative amount of animal protein used by inhabitants of the inland region may be obtained by comparing the areal densities of faunal remains from different sites. At CA -VEN -1130 this figure (calculated solely with reference to the 5 1x1 meter units containing cultural remains) is 0.34 gms/m2. At nearby CA -VEN -1135 this figure is 0.7 gms/areal m2 of excavation. At CA -VEN -535 and CA -VEN -654, both in Thousand Oaks, the figures are 11 gms and 20 gms/areal m2, respectively, while at CA -VEN -478, in nearby Tierra Rejada Valley, the comparable figure is 16 gms /areal m2. Mammal exploitation was minimal at CA- VEN -1130 and, in fact, generally minimal with reference to the Hidden Springs Ranch sites as a whole. There are two possible interpretations of this last fact. The first is that it indicates much more variability in inland resource exploitation than previously recognized. Even during the Intermediate period alone, there appears to have been considerable subsistence variability within the inland area. The second interpretation, which may not be exclusive to the first, is the possibility that CA -VEN -1130 and other sites within the study area may represent seasonal subsistence variability within an exclusively inland settlement system, whereas at least some of these other sites (particularly CA- VEN -535 and -654) may represent seasonal use of inland areas by part-time coastal dwellers. In either case, heretofore unrecognized variability in resource exploitation and therefore subsistence is the fundamental descriptive fact that emerges from the faunal analysis at CA -VEN -1130. 48 4.33 Miscellaneous artifacts A single miscellaneous artifact was recovered from CA -VEN -1130: a tarring pebble (Table 2). These were used to administer natural tar to the insides of baskets, to water -proof them. This artifact provides indirect evidence for the use of baskets at the site. 4.34 CA -VEN -1130 - Summary The artifact assemblage from CA -VEN -1130, in summary, provides a coherent even if limited picture of prehistoric activity at this locale. As regards chronology, CA -VEN- 1130 appears to be Intermediate in age, with at least some of the occupation continuing into the later portions of the Intermediate, after A.D. 500. No clear evidence for Late Prehistoric Period use of the site, however, was found. As regards site function, it is notable that the site served as a small habitation or camp. This is supported by the diversity of stone tools, in general terms, which reflect a relatively wide range of activities, as well as the emphasis on tertiary flakes in debitage, which usually result from tool finishing and maintenance activities undertaken at habitations. No real manufacturing or subsistence specialization is observable in the assemblage, however. Some plant processing occurred, as did some hunting, but both seem to be indicated in lower quantities than is often the case. No real evidence of trade or exchange was found in the assemblage from the site, which is itself notable. Lithic materials are all very locally available, with no exotics traded in (such as obsidian from the desert, which is often found in Intermediate Period sites). Likewise, no evidence for coastal trade (e.g., in the form of shell beads, shellfish remains or fish bone) was recovered. This suggests that the inhabitants of this site had little or no connections with the coast or, perhaps, with coastal inhabitants. Overall, CA -VEN -1130 is best interpreted as a dispersal phase camp or habitation, probably occupied seasonally by a small group with few or no ties to the coast. Existing chronological evidence suggests that the site dates to the later portions of the 49 Intermediate Period, to both before and after A.D. 500, but prior to A.D. 1200. 4.4 Artifact Assemblage: CA -VEN -1137 The prehistoric artifact assemblage from CA -VEN -1137 consisted of small collection of 147 specimens (Table 5). These included lithic tools (Table 6), debitage (Table 7) and faunal remains (Table 8). We discuss these artifact classes in turn. 4.41 Lithic Tools and Debitage Four formal or worked lithic tools were found at CA -VEN -1137 (Table 6). Three of these are core /cobble complex tools: one Type 1A uniface cobble chopper (Whitley et al 1979:12), made of a metavolcanic; and two Type 3, irregular core hammerstones (ibid:18). One of these is quartzite and the other is a metavolcanic. The fourth formal tool is a projectile point base made of gray fused shale (Figure 12). It is a straight -sided triangular point with a flat base (i.e., it is not tanged or stemmed). It appears to represent a relatively large arrow point, as opposed to an atlatl dart, and thus post -dates A.D. 500. Clearly, however, it is not one of the small and finely worked arrow points that are common after A.D. 1200 in this region. Thus it indicates that at least some of the occupation of the site occurred between about A.D. 500 and 1200, which is to say the later Intermediate Period. The debitage from CA -VEN -1137 is summarized in Table 7. A total of 141 pieces of this waste lithic was recovered from the site. As at CA -VEN -1130, fused shale was the most common of these, with 92 examples for 65.3% of the total. This was followed by chert, 20 or 14.2 %; quartzite, 15 or 10.6 %; and metavolcanics, 14 or 9.9 %. Again following the pattern established by the debitage collection at CA -VEN -1130, the waste assemblage from CA -VEN -1137 is dominated by tertiary flakes, with 64 pieces or 45.4 %. This is followed by angular shatter, 54 or 38.3°/x, and then by secondary flakes (12 or 8.5 %) and primary flakes (11 or 7.8 %), in almost equal 50 numbers. Again, no exotics or trade goods are present, with the majority of the debitage derived from local fused shale sources, and the emphasis in lithic reduction on tool finishing and maintenance. 4.42 Faunal Remains A very small quantity of faunal remains was found at CA -VEN -1137 (Table 8): two pieces of bone, weighing a total of only 0.9 gms. Bearing in mind the discussion of faunal remains above, both pieces of bone are fragments of rendered large mammal bones. Again, this is most likely indicative of prehistoric hunting activities but, clearly, activities that were of minor importance at the site. 4.43 CA -VEN -1137 - Summary The artifact assemblage from CA -VEN -1137 provides a fairly strong parallel to the artifacts described above from CA -VEN -1130, and thus suggest an equivalence in age and function. The only temporal diagnostic from the site, a projectile point, appears to date between A.D. 500 and 1200, assigning the site to the later part of the Intermediate Period. The diversity of artifacts in the assemblage implies no particular specialization, instead suggesting general habitation activities. This inference is bolstered by the importance of tertiary flakes in the debitage, which typically are associated with villages or camps. Although some hunting is suggested by the projectile point and animal bone, this was clearly minimal and, curiously, no groundstone, used for plant processing, was recovered from the site. The implication here is that the primary subsistence activity involved a resource and/or technology that we have not yet identified. No trade or contact with distant areas is evident in the assemblage, again suggesting a rather insular habitation, with the site probably seasonally occupied as a dispersal phase camp by an inland (as opposed to coastal) based small group. 51 4.5 Artifact Assemblage: CA -VEN -1138 The prehistoric artifact assemblage from CA -VEN -1138 consisted of collection of 327 specimens (Table 9). All of these were lithic artifacts: either formal tools, per se (Table 10); or lithic debitage (Table 11). 4.51 Lithic Tools and Debitage The formal lithic tools from CA -VEN -1138 are summarized in Table 10. They total 15 in number, with three core /cobble complex, three groundstone, and nine flaked stone tools. We discuss these below. .. Core /cobble complex tools from CA -VEN -1138 include one hammerstone and two choppers. The hammerstone is made of quartzite and is a Type 2A, minimally modified cobble hammerstone (Whitley et al 1979:15). Both choppers are metavolcanic, with one a Type 1A uniface and the other a Type 1 B biface cobble chopper (ibid:12). Groundstone Artifacts Groundstone artifacts from CA -VEN -1138 consist of three manos, made of three different stone types. The first is quartzite and is a Type 3, unshaped biface mano (ibid:38). The second is sandstone and is a Type 6 triface mano (ibid:46). The third is granite and is a Type 2 shaped uniface mano (ibid:38). Manos are of course indicative of plant grinding, perhaps of hard seeds. This assemblage indicates that some plant processing occurred at CA- VEN -1138. 6-15=7- -11073 rr•� Flaked stone tools were relatively common at CA -VEN -1138: nine of these were recovered, consisting of three unifaces, one biface and five projectile points. Two of 52 the unifaces are made of quartzite and the third is a metavolcanic; all are relatively crude uniface edges. The biface fragment, made of fused shale, is a crude but large biface edge. The projectile points (Figure 12) include the following: a relatively large leaf- shaped dart point made of chert (catalog #1138 -9), which predates A.D. 500; an arrow point tip made of fused shale ( #1138 -16), which post -dates A.D. 500; a Rose Spring Corner Notch base made of fused shale ( #1138 -17), dating between A.D. 500 and 1200; a fused shale arrow point midsection ( #1138 -18), post- dating A.D. 500; and a small convex base point made from fused shale ( #1138 -24), post- dating A.D. 1200. All of the projectiles points were either found on the groundsurface proper, or in the 0 -10 cm levels of test pits, which falls within the plow zone. The projectile points at the site indicate that CA -VEN -1138 was used during the Intermediate Period, prior to A.D. 500; that it continued to be used between A.D. 500 and 1200; and perhaps that it was used after that date, as suggested by the last point described above, which only became common in the region after about A.D. 1200- 1300. In fact, it is unclear whether or not the use of the site in any significant sense continued into the Late Prehistoric, since it is possible that the small arrow point is intrusive, and because two of the arrow points are untypable and therefore undateable fragments. Still, this indicates that at least some Late Prehistoric use of the general area occurred after A.D. 1200, it not CA -VEN -1138, per se. The debitage from CA -VEN -1138 is summarized in Table 11. Unlike most of the others sites considered during this Phase II test, an irregular metavolcanic core was recovered from the site (Table 10). The remaining 311 pieces of debitage were dominated by fused shale, with 235 examples, or 75.6% of the total. This was distantly followed by chert, 25 or 8 %; quartzite, 30 or 9.7 %; and metavolcanics, 21 or 6.8 %. Again following the patterns seen at the two previous sites, tertiary flakes were the dominant component of the debitage assemblage, with 194 examples for 62.4% of the 53 total. Second most common, however, were secondary flakes, with 50 or 16.1%, followed by angular shatter, 40 or 12.9 %; and then primary flakes, 27 or 8.7 %. 4.52 CA -VEN -1138 - Summary The artifact assemblage from CA -VEN -1138 is relatively large and diverse, suggesting that the site served as a habitation or camp. Hunting, tool manufacture and maintenance and plant preparation are all indicated in the artifact collection, in slightly greater degrees than at the previous two sites. The appearance is of a more balanced range of activities (relative to other sites in the region) than at CA -VEN -1130 and - 1137, although a number of strong parallels can be seen between this assemblage and those of the two previously discussed sites. Notable among these is, again, the absence of trade goods, exotics, ceremonial items, ornaments and coastal goods specifically. All of these circumstances suggest that the site served as a seasonal dispersal phase camp for a relatively insular population. The artifacts from CA -VEN -1138 provide the best chronological evidence recovered from the Hidden Creek Ranch sites although, as is almost always the case, the temporal position of the site is still slightly ambiguous. The site appears to have been used during the Intermediate Period both before and after A.D. 500, the point at which bows and arrows were introduced into the region. Four of the five projectile point fragments derive from arrows, indicating that post -A.D. 500 hunting and/or occupation was more intensive than previously. However, only one of these arrow points clearly post -dates A.D. 1200, so it is uncertain whether the majority of these temporally diagnostic artifacts date from the late Intermediate Period (A.D. 500 - 1200) or to the Late Prehistoric Period (after A.D. 1200). The general dearth of Late Prehistoric remains at these sites and those tested in 1994 (see W &S Consultants "1995) causes us to be cautious about the interpretation of the Late Prehistoric arrow point from CA -VEN -1138. While it clearly indicates use of the site area after A.D. 1200, it is possible that it is intrusive, in the sense of having been lost on the site during a hunting trip, after the site was abandoned. Still, even if CA- 54 VEN -1138 was occupied into the Late Prehistoric Period, the bulk of the evidence suggests that this was only minimally so, and that the site is primarily an Intermediate Period occupation, like the other midden sites examined during this project. 4.6 Artifact Assemblage: CA -VEN -1139 The prehistoric artifact assemblage from CA -VEN -1139 consisted of a single specimen (Tables 12 and 13): a secondary flake of fused shale. This represents a single prehistoric behavioral event, and thus is indicative of the general intensity of prehistoric use of this portion of the Hidden Creek Ranch area. Although this specimen is not itself datable, the large majority of the debitage from the surrounding habitation sites are also fused shale, increasing the likelihood that the creation of CA- VEN -1139 was related to the use of these nearby sites. 4.7 Artifact Assemblage: CA -VEN -1140 A total of 453 archaeological specimens were recovered during the Phase II test at CA -VEN -1140 (Table 14). These consisted of of 14 formal lithic tools (Table 15); 436 pieces of debitage (Table 16); and three specimens of faunal remains (Table 17), all of which are discussed below. 4.71 Lithic Tools and Debitage The formal tool assemblage from CA- VEN -1140 is summarized in Table 15. It includes five core /cobble complex, one groundstone and eight flaked stone tools. Core /cobble complex tools Core /cobble complex tools from CA -VEN -1140 include two hammerstones and three choppers. All five of these are made of quartzite. The hammerstones include a Type 2A, minimally modified cobble hammer, and a Type 3, irregular core hammer (Whitley 55 et al 1979:18). The choppers consist of two Type 1 B biface cobble chopper and one Type 1 A uniface cobble chopper (ibid:12). Groundstone Artifacts - A single groundstone artifact was recovered from CA -VEN -1140. This is a quartzite mano, indicative of plant processing at the site. It is a Type 3, unshaped biface mano (ibid:38). Flaked Stone Tools Eight flaked stone tools were recovered from the site: two unifaces; three bifaces; and three projectile points. Both of the unifaces are made of quartzite and are relatively large uniface edges. The bifaces are, likewise, relatively large and crude worked edges made on primary flakes with no overall shape modification. In size and form, these flake tools approximate smaller core /cobble complex tools, and may have served a function similar to biface and uniface choppers. The projectile points include two chert dart point fragments and a fused shale arrow point (Figure 12). One of the dart fragments is a large midsection. Although this fact precludes certain identification, it is long and relatively narrow but thick, suggesting that it is most likely one of the atlatl leaf- shaped points that are common in this region (e.g., artifact #138 -9). The second dart point includes a portion of either the tip or, if it derives from a leaf- shaped point (which seems likely), the base. It too, in other words, is most likely a leaf- shaped atlatl point. The third projectile point is a relatively large fused shale arrow point. This has a flat base and minor side - notching, creating what are almost "ears" on the side of the base. However, this point is neither an early side notch atlatl point, similar to the Northern Side Notch points in the Great Basin, nor a small Desert Side Notch point, which occurs after A.D. 1200. Instead, it appears to be a large arrow point similar to those that date between A.D. 500 and 1200. Based on the projectile points, CA -VEN -1140 appears then to have been occupied during the Intermediate Period, before and after A.D. 500, but not after A.D. 1200. t I .*- The debitage from CA -VEN -1140 is summarized in Table 16. As at the other sites examined during this Phase II test, fused shale was the most common material among the 436 debitage specimens recovered at the site: 239 pieces of fused shale were collected, representing 54.8% of the debitage total. These were followed by chert, 107 or 24.5 %, quartzite, 52 or 11.9 %, and metavolcanics, 38 or 8.7 %. Tertiary flakes were the most common class of debitage, with 262 specimens or 60.1 % of the collection. These were followed by angular shatter and secondary flakes in essentially identical numbers: 65 (14.9 %) and 64 (14.7 %), respectively. Primary flakes contributed 45 flakes (10.3 %). The debitage collection from CA -VEN -1140, in other words, closely paralleled that found at other midden deposits on the site, thereby signaling an emphasis on, locally available lithic resources, and tool finishing and maintenance. 4.72 Faunal Remains A very small collection of faunal remains was obtained at CA -VEN -1140 (Table 17). This consisted of two pieces of rendered large mammal bone, weighing 1.6 gms total, and a single weathered fragment of shell. This is Chione undatella, a clam species, and weighs 0.2 gms. Animal protein is, again, indicated as of minimal importance at the site. The presence of the single shellfish fragment, on the other hand, indicates the most minimal of access to coastal resources. The inhabitants of CA -VEN -1140 then clearly knew of these resources, but essentially had no means of obtaining them in any quantities. 4.73 CA -VEN -1140 - Summary The artifact assemblage from CA -VEN -1140 parallels quite closely the assemblages recovered from the other midden deposits within the Hidden Creek Ranch study area. 57 It appears to date to the Intermediate Period, including during the period between A.D. 500 and 1200, although also somewhat earlier. It contains a range of tool types, suggesting some diversity in manufacturing and especially subsistence activities. Plant processing, as indicated by groundstone tools, however, is all but unrepresented in the assemblage, further indicating that, if plant acquisition was important to the site's inhabitants (as seems very likely) it involved a technology that is either archaeologically unrecognized, or that does not preserve in the archaeological record. This circumstance must be emphasized by virtue of the fact that animal protein and hunting, as indicated by hunting tools and faunal remains, are also minimally represented in the assemblage. Still, CA -VEN -1140 appears to have been a small habitation locale, whose inhabitants emphasized the use of locally available resources. Outside trade or the use of exotic materials is nowhere indicated with one minor exception: a single fragment of shellfish. The paucity of this last material indicates that, while the site's inhabitants had some contact with coastal resources and/or peoples, this was all but non - existent. The inhabitants of CA -VEN -1140 were not part of the coastal interaction network that is seen at this same time in the Conejo Corridor. 4.8 Artifact Assemblage: CA -VEN -1141 The prehistoric artifact assemblage from CA -VEN -1141 consisted of a small collection of 10 specimens (Table 18), all of which were found on the groundsurface of the site. This included three formal tools (Table 19) and seven pieces of debitage (Table 19). The formal tools from the site are limited to two core /cobble complex tools and one hammerstone, all of which are metavolcanics. The core /cobble complex tools consist of a Type 1 B biface cobble chopper (Whitley et al 1979:12) and a Type 2 core chopper (ibid:15). The hammerstone is a Type 2B flaked cobble hammer (ibid:18). Seven pieces of debitage were found on the site (Table 20). These included a quartzite multiplatform core; three pieces of chert; two of fused shale; and one of quartzite. This included two secondary flakes and two pieces of angular shatter; and one primary and one tertiary flake. 4.81 CA -VEN -1141 - Summary CA -VEN -1141 is a surface lithic scatter that appears to have served as a very small unspecialized workshop, intended presumably to exploit locally available resources of various kinds. It does not appear to have been a quarry/workshop, per se, for two reasons. First, the presence of formal core /cobble complex tools made of metavolcanics on the site, and the absence of any metavolcanic debitage, argues that these tools were being used, but not made, at this location. Use of these large and crude tools in some other kind of activity, such as plant gathering or preparation, is then suggested. Second, the presence of fused shale debitage on the site indicates that at least some tool materials were brought in and worked at this location, even if from a relatively nearby location (Happy Camp Canyon), rather than quarried at this precise locale. Although we cannot specifically identify the kinds of activities that occurred at this site, beyond a minor amount of tool working, it is most likely that they were ancillary to the nearby habitation sites. This suggests that this site is similar in age to these habitations although, given the absence of any temporal diagnostic at the site, there is not way to test this proposition in an empirical sense. 4.9 Artifact Assemblage: CA -VEN -1142 A very small artifact assemblage was also collected from CA -VEN -1142. This consisted of only six archaeological specimens (Table 21): three core /cobble complex tools (Table 22); a core; and two pieces of debitage (Table 23). The formal core /cobble complex tools are all choppers. Two of these are Type 1 B biface cobble choppers; the other is a Type 1A uniface cobble chopper (Whitley et al 1979:12). One of the biface choppers is a metavolcanic; the remaining two choppers 59 are both quartzite. The debitage from CA -VEN -1142 includes a multiplatform quartzite core and one primary flake each of a metavolcanic and quartzite. 4.91 CA -VEN -1142 - Summary The small artifact assemblage from CA -VEN -1142 provides a fairly coherent picture of the activities that occurred at this site. Consisting of a lithic scatter associated with a lag deposit of cobbles, this site appears to have comprised a small quarry/workshop in which these cobbles were used to produce core /cobble complex tools. Thus, there are only two lithic types represented in the assemblage, quartzite and metavolcanics, both of which are found on the site. Importantly, both of these are also represented in the small debitage assemblage, too. Although there are no chronological data in this assemblage, it seems very likely that the site dates to the same time period as the nearby habitations, especially given that the kinds of tools that created at this site are also found in the tool assemblages from these nearby sites. 4.10 Artifact Assemblage: CA -VEN -1143 CA- VEN -1143 was another site that yielded a relatively small collection of artifacts and archaeological specimens. This consisted of eleven formal lithic tools and 74 pieces of debitage (Table 24). 4.101 Lithic Tools and Debitage The formal lithic tools from CA -VEN -1143 included six core /cobble complex, three groundstone, and two flaked stone implements (Table 25). We discuss these classes in turn. .$ • - ••• - • • - •• Core /cobble complex tools from CA -VEN -1143 consist of two choppers, three hammerstones and one scraper plane. The choppers include a Type 1A uniface cobble chopper, made of quartzite; and a Type 1 B biface cobble chopper, made from a metavolcanic (Whitley et al 1979:12). The three hammerstones are all Type 3 core hammerstones (ibid:18). Two are made from metavolcanics; the third is quartzite. The scraper plane, one of the few from the Hidden Creek Ranch sites, is a Type 1 core scraper plane (ibid:19). It is made from quartzite. Groundstone Artifacts Groundstone artifacts from CA -VEN -1143 consist of three manos, and are indicative of plant processing at the site, perhaps of hard seeds. They include one Type 1 unshaped uniface mano (ibid:38), made of quartzite, and two Type 4 shaped biface manos (ibid:43), one made of quartzite and the other of sandstone. Flaked Stone Tools The flaked stone tools include two artifacts. The first is a uniface edge made of chert. The second is a projectile point: a chert dart point that is roughly lozenge- shaped (Figure 12). This is both Intermediate Period in age, and predates the A.D. 500 introduction of the bow and arrow. Thus, CA -VEN -1143 dates sometime between 3500 and 1500 years B.P. Debitage The debitage from CA -VEN -1143 is summarized in Table 26. The debitage assemblage totals 74 specimens. Following the general pattern seen at the sites on the Hidden Creek Ranch, fused shale is the most common material present in the A debitage, with 37 pieces, or exactly 50 %. This is followed by chert (23 or 31.1 %) and quartzite (14 or 18.9°/x). Unlike the other sites, no metavolcanics were found in the debitage. Aside from this difference, the debitage assemblage otherwise closely resembles the other debitage collections when considered in terms of flake class. Tertiary flakes are the most common, with 49 or 66.2 %. These are followed by angular shatter, 13 or 17.6; secondary flakes, 7 or 9.5 %; and primary flakes, 5 or 6.8 %. One characteristic of the debitage assemblage from CA -VEN -1143 is notable relative to the other sites investigated during this Phase II test. This is the proportion of formal tools to debitage. At this site formal tools constitute 12.9% of all the lithic artifacts; a percentage that is, in fact, quite high. At CA -VEN -1130, for example, the comparable figure is 1.7 %; whereas it is 2.8% at CA -VEN -1137; 4.6% at CA -VEN -1138; and 3.1 % at CA -VEN -1140. CA -VEN -1143, then, has over twice as many artifacts per debitage specimen, relative to the other sites within the project area. This variability suggests that the amount of debitage present on a site is not directly related to the number of formal tools, which itself suggests that a significant number of the tools present on some sites were made elsewhere, and brought in completed. The habitation sites enumerated above, then, were not systematically used for stone tool manufacturing, instead only occasionally being so used. 4.102 CA -VEN -1143 - Summary The small assemblage from CA -VEN -1143 appears to reflect habitation activities of various sorts, including hunting, plant preparation and tool manufacture, though not necessarily of a systematic sort. More formal artifacts are present on this small site than at the other middens investigated during this project, by double, but there is still no evidence of activity of a true "formal" nature, such as ceremonies or the use of status displays or trade goods such as beads. The artifact assemblage from CA -VEN- 1143, then, is not so much different in kind from the other middens in Hidden Creek Ranch, but instead is an expression of one extreme of the range of variation to be seen 62 in this locality. As at the other sites, this deposit apparently dates to the Intermediate Period, specifically between 3500 and 1500 years B.P., with no evidence for use during the later part of this period (i.e., between A.D. 500 - 1200). 4.110 Artifact Assemblage: CA -VEN -1144 The prehistoric artifact assemblage from CA -VEN -1144 consisted of a small quantity of remains (Table 27): one formal artifact (Table 28); and eight pieces of debitage (Table 29). The formal tool is made of quartzite, and is a uniface edge made from a large primary flake. In size and form it approximates a core /cobble complex tool, and may have had the same function as a uniface chopper. The eight pieces of debitage include four metavolcanics flakes, two fused shale and one each of quartzite and chert. Five of these were primary flakes, two were secondary and one was angular shatter. 4.111 CA -VEN -1144 - Summary The artifact assemblage from CA -VEN -1144 most resembles that from CA -VEN -1141: a very small number of formal tools (in this case, one), and lithic debitage which, even though very limited in number, includes some lithic materials that are not immediately available at this particular locale. Our interpretation of the site then is that it is a small surface lithic scatter that served as some kind of unspecialized activity area. In part, the activities conducted at the site probably included the exploitation and reduction of the locally available quartzite and metavolcanic cobbles, but other activities may have occurred here as well. No temporal diagnostics were recovered from the site, so it is impossible to specify how old it is. However, it is most likely that it is coeval with the other sites in the Hidden Creek Ranch study area, and thus that it dates to the Intermediate Period. 63 4.120 Artifact Assemblage: CA -VEN -1147 The prehistoric artifact assemblage from CA -VEN -1147 consisted of single specimen (Tables 30 and 31): a quartzite secondary flake. It thus is similar to site CA -VEN -1139, which also contained only one piece of lithic debitage, and represents a single incident of prehistoric human behavior. Both sites are reflective of the intensity of aboriginal human use of the southeastern portion of the Hidden Creek Ranch and, while not directly datable, per se, logically were created at the time during which the nearby habitation sites were occupied and used. 4.130 Interpretive Concerns The test excavation of ten sites within the Hidden Creek Ranch study area revealed the presence of five camps or habitation sites (CA -VEN -1130, 1137, -1138, -1140 and - 1143); one small lithic scatter - quarry/workshop (CA -VEN- 1142); two small lithic scatters that served as unspecialized but variable activity areas (CA -VEN -1141 and - 1144); and two examples of isolated artifacts (CA -VEN -1139 and - 1147). The habitation sites all contained temporally diagnostic artifacts in the form of projectile points attributable to the Intermediate Period, or from about 3500 to 800 years B.P. A number of these sites also contained large and "early" arrow points that we date between A.D. 500 and 1200, indicating with some certainty that these habitations were used into the later portion of the Intermediate Period. Only one site contained clear evidence of Late Prehistoric Period use. This was CA -VEN -1138, where a single Late Prehistoric Period arrow point was recovered. We noted previously the hypothesis that a widespread abandonment of inland sites occurred approximately at the start of the Late Prehistoric Period, or sometime around AD 1200. Evidence for this has been found in the Santa Clara River Valley, immediately to the north of the Simi Corridor (W & S Consultants 1994b). Although the details of this seeming reduction in population and settlement have yet to be fully explored, this appears to be a process that extended from the western Great Basin 64 (Whitley 1994) and, in fact, throughout the greater Southwest, across the Mojave Desert and through the Antelope Valley (Sutton 1988). The evidence from the Hidden Creek Ranch sites tends to support this interpretation. Of the five habitation sites investigated during this Phase II project, only one showed evidence of site use continuing into the Late Prehistoric Period, and this evidence is relatively limited in nature. Similarly, the previous 1994 test excavations at other sites in the Hidden Creek Ranch study area revealed the presence of two additional habitation areas (CA -VEN -1134 and - 1135). These also date exclusively to the Intermediate Period (W &S Consultants 1995). As then appears clear, the Hidden Creek Ranch site complex is predominantly an Intermediate Period occupation, with only minimal evidence of use in the Late Prehistoric Period. Our best interpretation is that the sites were either abandoned, or population dropped dramatically, approximately at the transition to the Late Prehistoric Period at A.D. 1200. It is certainly possible that an untested Late Prehistoric village exists somewhere in the vicinity of the sites so -far investigated (e.g., immediately outside of the study area boundaries to the east). It is also clear that the entire span of the Intermediate Period represents a considerably longer period than the much shorter 600 years of the Late Prehistoric Period (i.e., 3500 - 800 years B.P, versus 800 to 200 years B.P.), meaning that if population size were constant, the evidence for Intermediate Period occupation should be about four times greater than the Late Prehistoric evidence. Yet as should also be clear, the evidence so far recovered from Hidden Creek Ranch provides clear evidence for the creation of seven Intermediate Period middens, and only very limited evidence for the partial use of one of these during the Late Prehistoric Period. By any measure, this suggests that there was a very significant drop in population after the Intermediate Period. We can then conclude that, while abandonment of the region, per se, did not occur at the end of the Intermediate Period, a dramatic drop in population certainly did. This, most likely, resulted from deteriorating environmental conditions that occurred around A.D. 1200. The Intermediate Period then can be interpreted as a time of favorable environment and large population, that contrasts with the smaller and essentially more 65 difficult times during the Late Prehistoric Period. This circumstance is notable for one reason. The approximate middle of the Late Prehistoric Period (around A.D. 1600) was marked by the first appearance of Europeans in California. This appearance was marked by the introduction of a series of European diseases, which most Native Californians had no natural immunity towards. One result was a series of epidemics and corresponding drops in population size. It is now clear, based in part on the evidence obtained from the Hidden Creek Ranch sites, that this population loss as a result of European diseases which was, itself, occurring within a population that was already suffering from environmental stress. While this does not deny the calamity of the European introduced plagues, it suggests that this loss of Native American life was partly a result of the bad environmental conditions that existed during this period. .. CHAPTER 5 CONCLUSIONS AND RECOMMENDATIONS 5.1 Summary and Conclusions Test excavations and determinations of significance were conducted at ten prehistoric archaeological sites, designated CA -VEN -1130, -1137, -1138, -1139, -1140, -1141, - 1141, -1142, -1143, -1144 and -1147, within the Hidden Creek Ranch study area, Moorpark, Ventura County, California. The Phase II fieldwork involved mapping, the surface collecting of groundsurface artifacts and archaeological indicators, and the hand excavation of test pits on each site, along with laboratory processing, cataloging and analyses of the recovered artifact collections. Five of these archaeological sites were found to contain relatively small and shallow midden or subsurface deposits. These sites are CA -VEN -1130, -1137, -1138, =1140 and -1143. The midden deposit at CA -VEN -1130 is estimated to be 145 by 45 meters in size; that at CA -VEN -1137 is 65 by 55 meters; at CA -VEN -1138, 60 by 100 meters; at CA- VEN -1140, 130 by 60 meters; and at CA -VEN -1143, 60 by 35 meters in size. Each of these sites dates to the Intermediate Period, or essentially between 3500 and 800 years B.P. One of these sites (CA -VEN -1138) also appears to have been used after A.D. 1200, although this Late Prehistoric use does not appear intensive or necessarily long - lived. The extant midden deposits at each of these sites are intact, maintain integrity, and therefore have the potential to provide scientific information useful for the reconstruction of the prehistory of this portion of Ventura County. The five remaining sites are all surface lithic scatters, each of which had a small artifact assemblage of. stone ' tools and debitage. CA -VEN -1141 and -1144 proved to be small, unspecialized activity areas, where a variety of prehistoric tasks were conducted. CA -VEN -1142 appears to have been a small quarry/workshop, where locally available cobbles were worked into stone tools. CA -VEN -1139 and -1147, in contrast, proved to be single isolated artifacts, both reflecting the general intensity of 67 prehistoric use of this portion of the Hidden Creek Ranch. Phase II fieldwork at these five small sites resulted in the recovery of all extant archaeological remains from each of them. 5.2 Final Recommendations The extant midden deposits at sites CA -VEN -1130, -1137, -1138, -1140 and -1143 represent significant archaeological resources. Development within the confines of these five site deposits therefore has the potential to result in adverse impacts to cultural resources. Following Appendix K of the California Environmental Quality Act (CEQA), we recommend that these adverse impacts be mitigated by site avoidance and preservation. This can be achieved by the preservation of these localities in open space. Such preservation could be achieved passively, by leaving the sites in their natural state. Alternatively, the incorporation of the site areas into open space. in the form of a golf course or green belts would also serve to preserve them and mitigate any adverse impacts. In such cases the site deposit areas should only be covered with landscaping fills, and care should be taken to insure that any necessary underground infrastructure (e.g., water lines) is not routed through the site deposits. This form of site preservation may be preferable to passive preservation in natural open- space, because it provides better insurance that the site areas will not be looted in the future. Should preservation and site avoidance be unfeasible, we recommend that Phase III data recovery (salvage excavations) be conducted at these five sites. Phase II testing at sites CA -VEN -1139, -1141, -1142 and -1144 has resulted in the recovery of all extant artifacts from these surface archaeological sites. This has obtained scientifically consequential information from and about each of these resources, and has served to completely and adequately mitigate any adverse impacts that might accrue to these five sites due to development on them. We therefore recommend that no additional archaeological work be required at these locales. Following Appendix K of CEQA, however, we recommend that an archaeological monitor be present when these localities are graded. In the unlikely event that .: subsurface remains are uncovered at any of these localities, this will insure that an archaeologists has the opportunity to record and collect these archaeological specimens. 6.0 CITED REFERENCES Arnold, J. 1987 Craft Specialization in the Prehistoric Channel Islands, California.

Privitt, AICP November 1997 SECTION 1 PROJECT DESCRIPTION PURPOSE OF STUDY Hidden Creek Ranch Speck Plan Spring Road Connection The purpose of this study is to address potential environmental impacts associated with the extension of Spring Road through Happy Camp Canyon Regional Park, and to determine if any impacts associated with this roadway extension would be different or more severe than the environmental impacts associated with the extension of Broadway Road through the park as addressed in the Hidden Creek Ranch Specific Plan Environmental Impact Report (EIR). BACKGROUND In September 1995, the City of Moorpark, as lead agency, released a draft EIR for the Hidden Creek Ranch Specific Plan (Specific Plan No. 8) project (State Clearinghouse No. 94021028). The draft EIR was made available for public review and comment for a 75-day period. Subsequent to the end of the review period, the city reviewed all comments made on the draft EIR and prepared written responses to all environmental comments provided on the Hidden Creek Ranch Specific Plan project. These responses to comments and revisions to the draft EIR (Volumes IV and V, respectively) were completed and provided to the City of Moorpark City Council and Planning Commission as well as made available to all parties commenting on the draft EIR. One of the project issues raised during public hearings of the City of Moorpark Planning Commission and in comments received on the draft EIR was related to the provision of an adequate circulation system to serve the proposed Hidden Creek Ranch Specific Plan project as well as the buildout of the city as envisioned in the City of Moorpark General Plan. The Hidden Creek Ranch Specific Plan draft EIR described and analyzed the potential project - specific and cumulative traffic impacts associated with the project. The primary components of the Hidden Creek Ranch Specific Plan project's circulation system was originally proposed as follows: • Extension of Campus Park Drive (east) into the Specific Plan site Hidden Creek Drive traversing the Specific Plan site in an east -west direction, and extending west through Happy Camp Canyon Regional Park and connecting to Broadway Road • A residential collector road from Collins Drive /Campus Road adjacent to Moorpark College to the southeastern commercial center Project Description Hidden Creek Ranch Speck Plan Spring Road Connection Construction of an interchange to the SR -118 from a new "Lagoon" interchange. It should be noted the draft EIR for the Hidden Creek Ranch Specific Plan EIR addressed this potential interchange as a circulation option or circulation mitigation. The purpose for this approach in the EIR was to determine if this interchange was needed to serve the project, as well as to determine if there were other circulation options to this interchange that could mitigate project - specific impacts and potentially better serve the circulation needs of the city. The EIR concluded that if other mitigation is implemented, the Lagoon interchange would not be required. The Hidden Creek Ranch Specific Plan draft EIR also addressed other transportation and circulation issues related to the proposed project and the city's circulation system (existing and proposed) to provide the decisionmakers with options. Section 4.8 of the EIR's Alternatives to the Proposed Project section addresses these circulation alternatives. The EIR notes, however, that these circulation alternatives (options) are not alternatives to the proposed Hidden Creek Ranch Specific Plan project. Therefore, no environmental documentation was prepared for these circulation alternatives. One of the alternatives to the extension of Hidden Creek Road (Broadway Road) through Happy Camp Canyon Regional Park is the extension of a road through the lower portion of the park. Because this would provide a roadway connection between the proposed Hidden Creek Ranch Specific Plan project site and the proposed Speck Plan No. 2 project site located west of the park, the Spring Road connection could serve both project sites as well as providing a roadway link to downtown Moorpark, which would not occur with the extension of Broadway Road. SPRING ROAD STUDY PROJECT DESCRIPTION In August 1996, the Moorpark Planning Commission recommended approval of the Hidden Creek Specific Plan project to the City Council. As a part of its recommendations to the Moorpark City Council, the Planning Commission indicated that the alignment of the roadway through Happy Camp Canyon Regional Park should be moved further north of the existing residences on Hastings, Lafayette, and East Cambridge. This Spring Road study has been updated to reflect the Planning Commission's recommendations to relocate the proposed alignment further north. As currently proposed, the connection through Happy Camp Canyon Regional Park would be constructed through the park extending into the Specific Plan No. 2 site immediately west and into the Specific Plan No. 8 site (becoming Hidden Creek Drive). As shown in Exhibit 1, the alignment is approximately 800 feet north of the nearest residence (an increase in distance of approximately 600 feet to the north); at the west end of the revised alignment (at Specific Plan No. 2), the roadway would be approximately 850 feet north of the southwest comer of Happy 2 Project Description Hidden Creek Ranch Speck Plan Spring Road Connection Camp Canyon Regional Park. The point of connection at Specific Plan No. 8 to the east remains the same (approximately 1,400 feet north of the park). The alignment curves northeasterly for its entire alignment within Happy Camp Canyon Regional Park. South of the alignment, park acreage would be approximately 48.6 acres. The expected traffic volumes on the Spring Road connection would require a two-lane roadway, as addressed in the Hidden Creek Ranch Speck Plan EIR. The roadway is proposed to be constructed as a two -lane Village Collector. A pedestrian /equestrian crossing (e.g., controlled stop, undercrossing) could occur where Happy Camp Canyon Road, an existing private paved access road through the park, crosses the proposed Spring Road connection. An at -grade crossing with stop signs at Happy Camp Canyon Road would be provided. Happy Camp Canyon Road (Campus Park Drive [west]) would not be improved nor is proposed to provide access to the proposed Hidden Creek Ranch Speck Plan project. No other improvements to Happy Camp Canyon Regional Park are proposed as part of the Hidden Creek Ranch Specific Plan project. 3 Project Description Specific Plal No. 2 Legend 0 Proposed Road Alignment Scale 1 inch = 400 feet 3idden Creek Ranch is Plan No. 8 EXHIBIT 1: Proposed Road Alignment Hidden Creek Ranch Specific Plan Spring Road Connection 2.1 EARTH RESOURCES Leighton and Associates, Inc. conducted a Geotechnical Investigation in June 1996 for the originally proposed alternative alignments of Spring Road through Happy Camp Canyon Regional Park. The geotechnical study contains a preliminary assessment of the potential geologic, soils, and seismic hazards which may affect any proposed roadway alignment that could be sited through the park as far north as where Broadway Road would traverse the park. This investigation is included as Appendix A to this study. A preliminary evaluation of the potential for faulting near the western boundary of the Specific Plan site was conducted by Leighton and Associates in November 1997; this investigation is also included in Appendix A to this study. EXISTING CONDITIONS Happy Camp Canyon drains southward near the eastern margin of the study area from an elevation of 860 feet above mean sea level (msl) in the north to 710 feet msl in the south. East of Happy Camp Canyon are south- and southeast - trending ridges that reach 940 feet msl. Bounding lower Happy Camp Canyon to the west and comprising the majority of the study area is a south - southwest sloping plateau that is dissected by small canyons. The relief in this area varies from 940 feet msl to 640 feet msl. The geologic units observed within the study area consist of nonmarine sediments that have been folded and tilted to the south - southwest (Dibblee, 1992a, b). The oldest sediments exposed within the study area are Pleistocene and Pliocene in age, approximately 200 thousand to 2 million years old. The youngest units, deposited in the active channels of the canyons that drain the site, are Holocene in age (less than 10,000 years old). An oversized exhibit (Plate 1 of Appendix A) depicts the geologic conditions of the study area and is available for review at the City of Moorpark Community Development Department. The geologic units present at the study area are listed below in order of relative age, with the youngest units first. Artificial Fill (at): Artificial fill that forms a fill slope was mapped in the southeastern comer of the study area on the eastern margin of Happy Camp Canyon. The fill slope contains a down -slope drainage channel and appears to be well maintained with water - seeking vegetation. Landslide Deposits (Qls): Most of the landslides that have been mapped occur along a 3,200 -foot long section of the western wall of Happy Camp Canyon, north of roadway alignments A, B, and C in the Saugus Formation (Plate 1). Typically, the landslides have occurred on slopes with gradients of 3:1 (horizontal:vertical/h:v) or steeper. These landslides appear to be rotational or slumps and generally consist of mixtures of rock fragments, soil, and debris from surface and underlying geologic units. Dense 2.1 -1 Earth Resources Hidden Creek Ranch Specific Plan Spring Road Connection vegetation is present within the landslide debris. The landslide deposits are often fractured, with cracks and voids within the landslide area, often down to the depth of the rupture surface. Additional landslides were mapped west of lower Happy Camp Canyon, predominantly on east- or southeast - facing, heavily vegetated slopes. Recent Alluvial Deposits (Qal): These sediments occur along the bottom of the active canyons that drain the area of study, and consist of gravel, sand, and silt. The alluvium is unconsolidated and generally undissected. This unit is of Holocene age, deposited in the last 10,000 years. 01derAlluvial Deposits (Qoal): Dissected, weakly consolidated older alluvial deposits comprise elevated terraces adjacent to the major south - flowing canyons that drain the study area. These sediments are derived from the rock units that occur within the study area, and consist of gravel and sand mixed with lesser amounts of silt and clay. Older alluvial deposits form the eastern wall of lower Happy Camp Canyon and appear generally stable at existing slope gradients ranging from 1:1 to 2:1 (h:v) with only minor areas of surficial slumping (Plate 1). These older alluvial deposits are of late Pleistocene age, deposited more than 10,000 years ago. Saugus Formation (QTs): The Saugus Formation is exposed on the western portion of the park, west of lower Happy Camp Canyon. In this area, the Saugus Formation consists of weakly consolidated floodplain and alluvial fan deposits of light gray pebble conglomerate, and pebbly /cobbly sandstone. The clasts consist predominantly of granite, although scattered clasts of gneiss, metavolcanics, quartzite, anorthosite, gabbro, and possibly Conejo Volcanics are also present (Dibblee 1992). The matrix consists of soft sand; interbeds of silty claystone may also be present. Saugus Formation bedrock is interpreted to underlie the Older Alluvium that comprises the eastern wall of lower Happy Camp Canyon. The Saugus Formation is interpreted to be of Pleistocene, and possibly Pliocene age, approximately 200 thousand to 2 million years old. Seismic Hazards The two principal seismic hazards to properties in southern California are surface rupturing of earth materials along fault traces and damage to structures and foundations due to strong ground motions generated during earthquakes. Numerous active and potentially active faults have been mapped within the southern California region, several within about 60 miles (100 km) of the site. Major faults that could produce significant ground shaking at the roadway include the Oak Ridge, Simi -Santa Rosa - Springville, San Cayetano, Santa Susana, Arroyo Parida -Santa Ana, San Gabriel, Santa Ynez, Malibu Coast, and Pine Mountain faults. Further information on each of these seismogenic sources can be found in the Hidden Creek Ranch Specific Plan EIR (Volumes I and V). 2.1 -2 Earth Resources Hidden Creek Ranch Specific Plan Spring Road Connection As a part of the evaluation of the Specific Plan No. 2 site located west of Happy Camp Canyon Regional Park, a zone of deformation caused by a blind thrust fault (referred to as the "Northern Site Area Thrust ") was identified (Pacific Materials Laboratory, Inc. 1997). This fault was inferred by Pacific Materials Laboratory to be active based on field and analytical data. This blind thrust fault was interpreted to be a projection of bedding planes from the underlying Tertiary bedrock in which its surface manifestation is the deformation of the Quaternary strata; its identification and analysis was aided by well preserved alluvium on the Specific Plan No. 2 site. The "Northern Site Area Thrust" fault generally trends to the northeast. Some geomorphic expression to the east of Specific Plan No. 2 suggests that this fault may cross Happy Camp Canyon Regional Park and extend toward the Specific Plan No. 8 site. The fault is located north /northeast of the proposed Spring Road extension through the park. The blind thrust faults on the Speck Plan No. 2 site have been interpreted by Pacific Materials Laboratory to be bedding plane faults. They are not considered to be seismogenic structures (they are not considered capable of generating earthquakes). Rather, activity on the blind thrusts is believed to occur co- seismically, possibly during moderate to large earthquakes on the Oak Ridge or Simi -Santa Rosa faults. The blind thrust faults and associated zones of deformation discovered on the Specific Plan No. 2 site represent potential ground rupture and ground deformation hazards. Ground rupture hazards presented by seismogenic faults are typically regulated by the California Alquist -Priolo Earthquake Fault Zoning Act. Ground deformation hazards (i.e., upwarping of the ground surface, typically in the hanging wall of the fault, as opposed to ground rupture) are not regulated by Alquist - Priolo. The lineament associated with the "Northern Site Area Thrust" was identified on aerial photographs and could be traced to the easterly edge of Happy Camp Canyon. As noted above, the fault is located north/northeast of the proposed roadway alignment through the park. This lineament was not observed on the eastern side of Happy Camp Canyon or on the Specific Plan No. 8 site, either because it does not exist or it is not observable due to a lack of well preserved alluvial surfaces and geomorphic expression on this lineament. An east -west trending lineament observed north of the Specific Plan No. 2 site has not been projected to extend into Happy Camp Canyon Regional Park. A similar trending lineament was observed between the park and the Specific Plan No. 8 site. Aerial photographs also depict an east -west trending canyon between Planning Unit 39C to the north and Planning Units 32 and 33 on the south on the Speck Plan No. 8 site. This drainage feature is considered anomalous because it is east -west trending in an area of the Specific Plan site dominated by north -south trending drainages. This feature could not be traced to the west of these planning units into Happy Camp Canyon Regional Park. 2.1 -3 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection The following sections detail the primary and secondary seismic hazards to the roadway study area. Seismic Ground Shaking An earthquake occurs when the elastic strain energy that has accumulated in the bedrock adjacent to a fault is suddenly released. The energy released propagates in the form of seismic waves that radiate great distances in all directions from the earthquake epicenter. The strong ground motion or shaking produced by these seismic waves is the primary cause of earthquake damage. How much the ground shakes at any one point depends primarily on the earthquake magnitude, distance, and direction from the earthquake source, and the local geologic conditions, which can either amplify or attenuate the earthquake waves. Several secondary effects are generally associated with strong seismic shaking, especially in areas characterized by a relatively shallow groundwater table, and underlain by loose, cohesionless deposits. These effects are discussed below: Liquefaction: Liquefaction occurs when loose, cohesionless, water saturated soils (generally fine- grained sands) are subjected to strong seismic ground motion of significant duration (Tinsley, et al. 1985). These soils essentially behave as liquids, losing all bearing strength. Structures built on these soils tilt or sink when the soils liquefy. Liquefaction generally occurs in earthquake -prone areas underlain by recent unconsolidated alluvium where the groundwater table is less than 50 feet below the ground surface. Within lower Happy Camp Canyon, the proposed road alignment will be located upon potentially water - bearing alluvial sediments. Regional groundwater flow is probably to the south, parallel to the axis of the canyon. Seismically- induced Settlement: Strong ground shaking can cause subsidence and settlement by allowing sediment particles to become more tightly packed, thereby reducing pore space. Unconsolidated alluvial deposits are especially susceptible to this phenomenon. Artificial fills, if not adequately compacted, may also experience seismically- induced settlement. Ground Lurching: Certain soils have been observed to move in a wave -like manner in response to intense seismic ground shaking, forming ridges or cracks on the ground surface. At present, the potential for ground lurching to occur at a given site can be predicted only generally (Ziony and Yerkes 1985). Areas underlain by thick accumulations of alluvium or colluvium appear to be more susceptible to ground lurching than bedrock. 2.1 -4 Earth Resources Hidden Creek Ranch Specific Plan Spring Road Connection Slope Stability The descending slopes bounding lower Happy Camp anyon are generally susceptible to landsliding. The slopes on the eastern side of lower Ha py Camp Canyon are composed of Older Alluvial Deposits (goal) and appear to be stable u der their present natural conditions, with the exception of minor shallow slumping, at slopes ranging from 1:1 to 2:1 (h:v). However, in contrast, the slopes that bound the western side of lower Happy Camp Canyon are composed of Saugus Formation (QTs) bedrock and are often unstable based on recent field observations of shallow slumps and /or rotational landslides. These failed slopes have gradients of 3:1 (h:v) or steeper. West of lower Happy Camp Canyon, east - facing and southeast- facing slopes appear to be generally less stable than west - facing slopes. On these east- and southeast - facing slopes, several landslides were mapped within Saugus Formation bedrock. Bedding attitudes across the study area were difficult to obtain during this investigation due both to the dense vegetative growth covering the majority of the canyon walls and the lack of observable bedding within bedrock. Only one bedding attitude was obtained west of lower Happy Camp Canyon, striking N25 °W and dipping 8 0SW. In addition, adjacent to the western margin of lower Happy Camp Canyon, geomorphic features suggested a southwesterly dipping slope. Geologic structure was not able to be determined in the eastern portion of the study area. In the western portion of the study area, geologic structure suggests southwest dips. However, existing landslides that bound the western margin of lower Happy Camp Canyon suggest that bedrock failure can occur in the Saugus Formation across bedding planes, particularly where slopes are steeper than 2:1 (h:v). Cut slopes oriented such that a significant out -of -slope bedrock dip is created would increase the potential for slope failure. However, this should be confirmed by a geotechnical engineer who would perform a slope stability analysis for static and dynamic loading conditions based upon the results of a subsurface geotechnical investigation. The alluvial deposits and bedrock that are present are generally suitable for use as compacted fill material, provided that they are moisture conditioned as necessary, and organics and other deleterious materials are removed. Roadway Foundation Stability Alluvial deposits mantle the floor of lower Happy Camp Canyon and the majority of the south - trending canyons west of the lower canyon. Based upon Leighton and Associates analysis for the Hidden Creek Ranch Specific Plan project, the near - surface alluvium within lower Happy Camp Canyon and all alluvium in the smaller adjacent, south - trending canyon is likely to be 2.1 -5 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection typically unconsolidated to poorly consolidated, with medium to high permeabilities as a result of its coarse fraction content. These soils are considered moderately to highly compressible. Expansive materials, if left untreated, can cause damage to structures, including cracking, heaving, and buckling of roadway surfaces and slope surfaces. Alluvial deposits in the study area are predominantly coarse grained, and probably have a low to moderate expansion potential. However, based upon work performed for the proposed Hidden Creek Drive Specific Plan project east of the roadway study area (Leighton 1994), small localized areas of highly expansive soils may occur onsite. Clays with a moderate to high expansion potential have been observed within shale and claystone interbeds of the Saugus Formation in other areas of Ventura County. Erosion and Flooding The erosion potential of many of the deposits that crop out at the proposed roadway study area is considered to be moderate to high. Erosion is most prevalent in the younger and older alluvium, and the Saugus Formation, all of which are prone to severe rills, sheet wash, slumping, and bank failures and flows during and after heavy rainstorms. These materials would be particularly prone to erosion during the construction phases of the Spring Road connection, especially during periods of heavy rains. However, once the cut slopes have been established and landscaping vegetation is established, the erosion potential of these deposits will diminish significantly. Erosion north and south of the road alignment that would be left in their natural condition would be similar to current levels, provided that the road design incorporates erosion control measures. The portions of the roadway alignment that traverse lower Happy Camp Canyon is located within a Flood Zone A, an area of a 100 -year flood. Within this area, base flood elevations and flood hazard factors have not been determined. IMPACTS Significance Criteria Impacts to earth resources are considered significant if a project results in extensive cut and fill volumes or heights. Impacts which violate or are in conflict with any federal, state, or local policies, ordinances, or regulations are considered significant. Significant geologic impacts may result if the project exposes people or structures to major geologic hazards and/or permits development in areas of unsuitable geologic condition. 21 -6 Earth Resources Hidden Creek Ranch Specific Plan Spring Road Connection Impacts Several constraints have been identified that present either a potentially significant or significant impact to the proposed road alignment. These constraints are earthquake damage (liquefaction, landslides, differential compaction /seismic settlement, and ground shaking), slope stability, roadway foundation stability, and erosion and flooding. Based upon this study, and provided appropriate mitigation measures are incorporated into site design and construction, the proposed alternative roadway alignment for the Spring Road connection is considered feasible. Seismic Hazards As with most of southern California, moderate to high intensities of ground shaking can be anticipated in the study area. The study area is located between the.Oak Ridge fault to the north and the Simi -Santa Rosa fault system-to the south. These faults are estimated to be capable of generating an earthquake of up to magnitude 6.9. Such events could result in horizontal ground accelerations of 0.5 to 0.7g at the roadway. Earthquakes on more distant faults could be expected to produce peak horizontal ground accelerations of up to 0.5g. A maximum duration of ground shaking of 50 seconds is expected to occur as a result of an earthquake on the Carrizo segment of the San Andreas fault. The proposed roadway alignment is located within seismic zone 4 of the Uniform Building Code, 1991 edition. Seismic shaking at the study area is considered to be a significant impact prior to mitigation. Observation of the °northern Site Area Thrust" on the Speck Plan No. 2 site does not preclude the implementation of a roadway connection through lower Happy Camp Canyon Regional Park. The unconsolidated, alluvial sandy deposits that occur within lower Happy Camp Canyon could be susceptible to liquefaction if perched or regional groundwater is present within 50 feet of the ground surface. However, proven geotechnical construction methods can either reduce the potential for these deposits to liquefy or even eliminate the need to have to address the phenomenon of liquefaction altogether. The potential for the occurrence of liquefaction is considered a potentially significant impact prior to mitigation. Since extensive unconsolidated alluvial deposits exist within lower Happy Camp Canyon, seismic settlement within the study area is considered a potentially significant impact prior to mitigation. Under strong seismic ground motion conditions, lurching can be expected within loose, cohesionless soils, or in clay -rich soils with a high moisture content. Pavements tend to be susceptible to damage by ground lurching; more heavily loaded structures appear to resist such 2.1 -7 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection deformation. Therefore, ground lurching due to seismic shaking is considered to pose a potentially significant impact. Slope Stability The conceptual plan for the proposed road alignment shows that the alignment only enters areas of potential slope instability where it converges at the western and eastern margin of lower Happy Camp Canyon. In the west, based upon limited geologic structural data, bedding within the Saugus Formation has a southwesterly dip. Graded, southerly facing slopes that are created during road construction could create an out -of -slope dip component leading to potentially unstable slope conditions. Unstable slope conditions may also develop if slopes are loaded at the top, support at the toe or sides is removed, or if adequate drainage of surface and subsurface waters is not provided. Unstable slope conditions can occur in temporary cut slopes, especially if seepage associated with perched or shallow groundwater conditions saturates the exposed soil materials. In trenches where bedded materials are exposed, stockpiling the excavated material on the side of the trench where bedding dips out of the trench walls can result in unstable conditions. The potential for slope instability due to road construction at the site is considered a significant impact. Several shallow surficial failures and debris flow scars have been mapped (Plate 1 of Appendix A). In some areas, these deposits could affect the proposed roadway development. During periods of intense rainfall, debris -laden runoff waters emanating from the canyons west of Happy Camp Canyon could also pose a mudflow or debris flow hazard. Surficial slumping and debris flow hazards are considered a significant impact prior to mitigation. Due to localized folding of the bedrock, some slopes may cross geologic planes of weakness and may therefore require stabilization. The most common approach to slope stabilization is buttressing with compacted fill. Buttress fills should be graded no steeper than 2:1 (h:v) without geotechnical reinforcement. The grading of the cut slopes is considered a potentially significant impact prior to mitigation. Roadway Foundation Stability The near - surface alluvium in the study area has medium to high permeabilities as a result of its coarse fraction content. These soils are considered moderately .to highly compressible. Landslide deposits are also generally considered compressible. Colluvial soils vary widely in density and porosity, but are generally considered to be compressible if subject to loading from 2.1 -8 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection artificial fills or structures. Settlement of these soils may occur if either fill or structures are placed directly on them. This is considered a significant impact. The geotechnical hazard posed by soil expansivity is low to moderate in the area and is considered a potentially significant impact. During wet winters, debris flows emanating from the canyons, especially along the south - trending narrow canyons west of Happy Camp Canyon, could pose a serious threat to life and property if appropriate mitigation measures are not implemented into roadway design. This is a potentially significant impact. CUMULATIVE IMPACTS Generally, geotechnical issues are site - speck and would be limited to within the development boundaries of the roadway; therefore, no cumulative earth resources impacts are anticipated. MITIGATION MEASURES Seismic Hazards Trenches shall be excavated in areas where identified lineaments may project through the Spring Road alignment. This work shall be conducted during the preliminary geotechnical investigation for the Hidden Creek Ranch Specific Plan No. 8 project Master Tentative Map. If active faulting or deformation is observed in the trenches, then a certified geologist and geotechnical engineer shall provide specific mitigative recommendations for roadway development. 2. There is no realistic way in which the hazard of seismic shaking can be totally avoided. However, design in accordance with current regulations and grading codes at the time of construction can be expected to satisfactorily mitigate the effects of ground shaking. Existing landslides may be prone to slope instability during strong ground shaking. If any portion of a landslide is left in place without stabilization and could reasonably impact the Spring Road extension, then it is prudent to analyze the stability under seismic loading conditions. 3. The potential for damage due to liquefaction of the sediments in Happy Camp Canyon shall be mitigated. Such measures may include deep piles or caissons, that are founded on non - liquefiable sediments, or mechanical densification of the subsurface soils of an at -grade roadway. The area along the Spring Road extension west and east of Happy Camp Canyon, where localized unconsolidated alluvial deposits coupled with shallow or perched groundwater conditions may occur, may be susceptible to liquefaction. However, these shallow deposits can be removed and replaced with compacted fill as part of normal grading activities. Additionally, the placement of subdrains along canyon bottoms will help to remove groundwater that may develop at 2.1 -9 Earth Resources Hidden Creek Ranch Specific Plan Spring Road Connection or above canyon bottom elevation. During the site geotechnical investigation, a geotechnical consultant shall evaluate areas of sandy alluvial soils within the proposed area of development that will not be removed during normal grading operations for potential liquefaction and provide appropriate mitigation measures as necessary. 4. Loose, unconsolidated alluvial deposits underlying the Spring Road extension area shall be removed and replaced with compacted fill. Areas underlain with existing artificial fill shall also be identified and the fill materials removed and recompacted. Mitigation alternatives include in -situ dens cation of the near - surface soil materials to decrease their susceptibility to settlement or foundations on piles or caissons extended into deeper subsurface materials that are not settlement prone for elevated roadway structures. 5. Loose, cohesionless soils that may be susceptible to ground lurching shall be identified, removed, and recompacted, if feasible. For roadways that are constructed on the ground surface, there are locations at which there is no realistic way in which the hazard of ground lurching can be totally avoided. However, construction of roadways using asphaltic concrete as opposed to other surfaces, will allow for quick, relatively easy repair or reconstruction of damaged areas. The affects of ground lurching on the Spring Road extension shall be evaluated during the geotechnical investigation. Otherwise, deep piles or caissons may be needed to fully mitigate this potential impact. 6. The landslides that occur along the western margin of lower Happy Camp Canyon that could affect the Spring Road extension shall be evaluated to determine their lateral extent, depth, and potential instability due to the proposed grading. Partial to complete removal of the landslides may be necessary to mitigate the potential for renewed movement of landslide materials across the road alignment. At both the western and eastern margins of lower Happy Camp Canyon, subsurface geologic structure and the strength of existing geologic materials (and thereby the potential for slope instability) shall be determined. This would generally be accomplished during a subsurface geotechnical investigation for the Spring Road alignment. 7. In areas west of lower Happy Camp Canyon where slopes would be impacted by the Spring Road extension, the identified landslides (Plate 1) shall be evaluated further to assess the most effective remedial measures to be applied. A geotechnical investigation that includes a subsurface investigation shall be performed. Possible remedial measures include the construction of shear keys and/or the establishment of setbacks; stabilization of landslides is preferred. This is generally accomplished during a subsurface geotechnical investigation for the road. 8. Surficial landslide deposits and debris flow deposits shall either be removed or contained by retaining devices where there is potential to affect the Spring Road extension. Because of the compressibility of these deposits, removal within development areas is generally the preferred method to minimize post- construction settlement. 2.1 -10 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection 9. The stability of proposed cut slopes associated with the Spring Road extension shall be evaluated by a geotechnical engineer during the geotechnical grading plan review. The engineer shall recommend the most appropriate mitigation measure for each case. Measures that can be used to stabilize slopes include buttress fills, flattening of the slope angle, and in some cases, retaining walls. Use of geotextiles and landform contour slope designs can be incorporated into the road design to create natural- appearing graded topography and increase slope stability. For fill slopes, if the natural moisture content of bedrock materials is below the optimum moisture content for proper compaction, the soils would require the addition of water during grading. Any oversized materials (greater than 8 inches in diameter) shall be placed in either deeper portions of the fills (if fill materials are required) according to accepted methods of windrowing, or should be removed from the site. Roadway Foundation Stability 10. Partial to complete removal and recompaction of the alluvial deposits to geotechnically competent materials in the canyons shall be required in areas affected by the Spring Road extension through Happy Camp Canyon Regional Park. The depth of alluvial materials that should be removed in order to mitigate settlement shall be determined by analysis performed by a geotechnical engineer during the geotechnical investigation of the alignment area. 11. To allow for the implementation of the Spring Road extension through Happy Camp Canyon Regional Park, compressible materials that will probably require removal west of lower Happy Camp Canyon include topsoil, colluvium infilling swales and landslide grabens, surficial slumps, debris flows, landslide debris, and unengineered fills. Prior to the start of grading, the area traversed by the roadway alignment should be stripped of vegetation and debris and disposed of in an acceptable manner. Irrigation lines, abandoned underground storage tanks (if encountered), and water and oil wells (if encountered) should be removed or capped. The water and oil wells must be abandoned following the guidelines established by the California Division of Oil and Gas. Care must be taken to identify and mitigate any sump deposits encountered onsite. Prior to placement of compacted fill, all compressible materials shall be removed. Deep canyon fills are expected to undergo secondary settlement. Depending on the type of fill materials used, most of the settlement will occur during and immediately after grading. In order to determine when settlement is complete, laboratory testing and analysis by a geotechnical engineer should be performed for as- graded conditions. 12. Determination of expansivity and development of appropriate remedial measures should be performed by a geotechnical engineer prior to final design of the Spring Road extension through Happy Camp Canyon Regional Park. This evaluation is usually performed during the subsurface geotechnical investigation. If expansive clay is encountered at shallow depths, it may be recommended that clay -rich soils be removed and replaced with a specified thickness of nonexpansive granular soil beneath the roadway. Mixing during grading of localized expansive soils with the more common, granular nonexpansive soils present should be sufficient to mitigate this impact. Alternatively, mitigation of expansive- soils can be accomplished during 2.1 -11 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection construction by pre- saturation of the expansive materials and/or reinforcement of the roadway base. Erosion and Floodinst 13. Temporary erosion control measures shall be provided for the Spring Road extension during the construction phase, as required by current grading codes. In addition, a permanent erosion control program should be implemented for the road. This program should include proper care of drainage control devices, proper irrigation, rodent control, and landscaping. Debris and /or retention basins may be designed by the project's civil engineer to ensure that post - development runoff levels are comparable to undeveloped levels, and to mitigate any debris flows that may originate from the northern, undeveloped portions of the road alignment west of Happy Camp Canyon. Erosion control devices should be field- checked following heavy rainfall periods to confirm that they are performing as designed. 14. Drainage for the Spring Road extension shall be designed in conformance with code requirements. CONCLUSIONS With implementation of the measures listed above, impacts associated with roadway foundation stability will be reduced to a level considered less than significant. With implementation of the mitigation measures listed above and compliance with standard federal, state, and local building codes, impacts associated with seismic activity, slope stability, and erosion will be reduced to a level considered less than significant. 2.1 -12 Earth Resources Hidden Creek Ranch Speck Plan Spring Road Connection 2.2 WATER RESOURCES A Hydrology and Drainage Report prepared by The Haaland Group, Inc. in October 1994 for the Hidden Creek Ranch Specific Plan site provided information, technical data, and results for the existing and developed conditions of the Hidden Creek Ranch Speck Plan site and Broadway Road connection through Happy Camp Canyon Regional Park. In July 1996, the Haaland Group, Inc. prepared supplemental information focusing on the potential extension of a roadway through lower Happy Camp Canyon Regional Park. Hydrologic data and calculations were performed in accordance with the Ventura County Flood Control District's (VCFCD) procedures outlined in the 1975 Hydrology Manual. This section summarizes the results of the Hydrology and Drainage Report which is included as Appendix B of this study. EXISTING CONDITIONS Surface Drainage Patterns and Flows The potential roadway alignment for the Spring Road connection lies within the watershed of Happy Camp Canyon. The Happy Camp Canyon watershed is approximately 7,383 acres and is almost entirely in a natural condition. Runoff from the area north of the Big Mountain ridgeline flows westerly and then southerly near the southwestem portion of the proposed Hidden Creek Ranch Specific Plan site. Runoff from the watershed enters an improved channel at the northern boundary of Tract 2453 near the terminus of Campus Park Drive (west). The channel is under the jurisdiction of the Ventura County Flood Control District (VCFCD). There is no evidence of improvement with respect to that portion of the channel within the immediate vicinity of the study area. Originally designed and constructed in the 1960s, Happy Camp Channel is an open concrete trapezoidal channel north of SR -118, transitioning to reinforced concrete double boxes where the channel crosses under streets. Surface Water lity Qua Water quality in the receiving waters downstream of the roadway study area is potentially affected by discharges of stormwater runoff from surrounding urban development. Because the study area is undeveloped, surface waters immediately downstream should maintain good water quality in terms of mineral content, organic and nutrient load, and toxic contaminants. The primary pollutants of concern in rurallagricultural runoff include fine suspended solids, pesticides, herbicides, and nutrients, notably nitrogen and.phosphorous compounds. Limited uses within Happy Camp Canyon Regional Park are not expected to have resulted in elevated levels of pollutants in downstream areas. 2.2 -1 Water Resources Hidden Creek Ranch Specific Plan Spring Road Connection Flows within the Happy Camp Canyon channels converge with No. 2 and Strathern Canyon channels to eventually merge into the Arroyo Simi which receives year -round flows from the Simi Valley Water Treatment Plant. Further downstream, after the Arroyo Simi converges with the Conejo and Calleguas Creeks, treated wastewater from the cities of Camarillo and Thousand Oaks are discharged into the channel. The approximate amount discharged by these wastewater treatment plants into the Conejo/ Calleguas watershed are identified in Table 2.2 -1. TABLE 2.2 -1 WASTEWATER TREATMENT PLANT DISCHARGES In 1993, the Moorpark Wastewater Treatment Plant (MWTP), which is operated by the County of Ventura Water Works District No. 1 (WWD No. 1), treated and discharged approximately 1.9 million gallons per day (mgd) of treated effluent which was used for recharge of the local aquifer via percolation ponds. The MWTP has since been upgraded to a tertiary treatment level and is permitted to discharge directly into the Arroyo Simi. The treatment plant currently receives 2.0 mgd and has a capacity of 3.0 mgd, with a state discharge permit for 1.5 mgd. Generally, water discharged from water treatment plants contain high levels of total dissolved solids (TDS), nitrogen, and phosphorous. The State Regional Water Quality Control Board (RWQCB) Water Quality Control Plan, Los Angeles Region, identifies several beneficial uses for the Arroyo Simi, including industrial service supply, municipal supply (potential), groundwater recharge, fresh water replenishment, water contact recreation, noncontact water recreation, warm fresh water habitat, and wildlife habitat. Downstream waterbodies, including Arroyo Las Posas, Calleguas Creek, and Mugu Lagoon also support these beneficial uses, as well as additional uses including rare species habitat and wetland habitat. 2.2 -2 Water Resources Current Discharges Projected Discharges Treatment Plant (mgd)' Year 2000 d Discharge Point Camarillo 4.0 -4.2 5.8 Conejo Creek (3.0 mgd used for irri ation Simi Valley 9.2 15.5 Arroyo Simi (0.1 used for irrigation) Thousand Oaks 9.2 14.0 Conejo /Mugu Lagoon Hill Canyon Olsen Road 0.25 -0.30 0.50 Calleguas-Conejo Creek ' Million gallons per day.

Downstream waterbodies, including Arroyo Las Posas, Calleguas Creek, and Mugu Lagoon also support these beneficial uses, as well as additional uses including rare species habitat and wetland habitat. 2.2 -2 Water Resources Hidden Creek Ranch Specific Plan Spring Road Connection Ventura County was designated a 208 Water Quality Management Plan planning area in 1974 under the terms of the federal Water Pollution Control Act Amendments of 1972 (Public Law 92- 5000). The 1972 amendments require the restoration and maintenance of the integrity of the nation's water and to achieve a level of water quality which provides for recreation in and on the water, and for the propagation of fish and wildlife. The county's 208 Plan sets forth goals, policies, and program recommendations for water quality issues to protect and enhance county's water resources. Flooding According to the Flood Insurance Rate Maps (FIRM; community panel numbers 0604130825B and 06041308158), Happy Camp Channel is within Zone A which indicates areas of 100 -year floods. Groundwater Ventura County contains 32 recognized or potential groundwater basins. Some of these groundwater basins are composed of geologically "recent" sands and gravels deposited by rivers and oceans within the last 10,000 years. The study area is within the North Las Posas Groundwater Basin as designated by the state Department of Water Resources. Currently, rain that falls on Happy Camp Canyon and is absorbed into the ground is either taken up by vegetation, evaporates, or moves through the soil in a downslope direction towards the Arroyo Simi. This soil water flow may percolate down to the groundwater on route to the Arroyo Simi and once in the channel may percolate through the streambed to the water table. Rainfall may reach the Arroyo Simi via the Happy Camp Channel and then percolate through the streambed to the water table. As the Arroyo Simi continues downstream, it supplies water to the North Las Posas Groundwater Basin. The North Las Posas Basin experienced high levels of overdraft (pumping in excess of recharge) through the 1980s and 1990s; this condition is expected to continue into the 21st century. In the North Las Posas Basin, water levels in the easterly portion of the basin, east of Balcom Canyon Road, continues to recede. A task report prepared by the Groundwater Management Agency suggests that increased extractions in the basin would lower levels from 200 to 300 feet between 1980 and 2010. Such lowering of water level would cause some areas to become dewatered around the eastern periphery of the basin. 2.2 -3 Water Resources Hidden Creek Ranch Specific Plan Spring Road Connection IMPACTS Significance Criteria Surface Drainage Flow. Significant impacts would result if the roadway were to increase peak runoff rates in excess of downstream capacity. Significant impacts to surface water resources would occur if uncontrolled runoff results in increased erosion and subsequent sedimentation of downstream water bodies. Surface Water Quality. Impacts on surface water quality would be considered significant if they resulted in human health and safety impacts. Changes in water quality that effect biological communities would also be considered significant. Flooding. Significant impacts would result if the roadway would impose a flood hazard onsite or on adjacent properties, or expose people or property to risk. Groundwater. The roadway would be considered to have significant impact on groundwater if it resulted in groundwater withdrawals in excess of the safe yield in the groundwater basin or if it significantly reduced the amount of recharge to an aquifer. Significant impacts on groundwater quality may also result if human health and safety are put at risk. Surface Water Drainage and Flows The hydrology study is based upon VCFCD's capital flood hydrology for the Happy Camp Canyon channel. The major changes in the watershed runoff process in urbanizing areas are due to two principal factors: the increase in impervious surfaces due to development and the increase in hydraulic conveyance capacity due to the construction of flood control channels and pipe systems. These factors influence both runoff quantity and quality from urbanized areas. Post - development drainage would result in approximately six acres of impervious surfaces. It should be noted that the Hidden Creek Ranch Specific Plan EIR assumed the extension of Broadway Road through Happy Camp Canyon Regional Park. The Spring Road connection would replace the Broadway extension. Therefore, the increase in impervious surfaces through lower Happy Camp Canyon associated with the Spring Road connection would not be cumulative. The proposed roadway is within subarea 120F and F portion of area 122A of the watershed. Since the majority of the proposed road would be within sube 20F, only this subarea was modified to model potential impacts. As noted above, the im, tation of the roadway would result in approximately six acres of impervious surfaces ±a results in an increase in 2.2-4 Water Resources Hidden Creek Ranch Speck Plan Spring Road Connection impervious surfaces within subarea 120F from 0 to less than 8 percent. Locally to subarea 120F, the increase in runoff is approximately 4 cubic feet per second (cfs), a 2.75 percent flow increase. Within the total 7,383 -acre Happy Camp Canyon watershed, the increase runoff represents less than 0.06 percent. This increase is not considered locally or regionally significant. Surface Water lity Qua Roadway construction activities may incrementally increase the amount of onsite erosion which could increase sedimentation in the Happy Camp Canyon watershed. The use of construction equipment can increase the chance of toxins such as oil, gas, and solvents entering creeks. Urban contamination within stormwater discharges is a primary concern for the National Pollutant Discharge and Elimination Systems ( NPDES) stormwater discharge regulations that affect new construction sites (over 5 acres in size). Implementation of the roadway will require a permit from the RWQCB; it is anticipated that a "general" permit will be adequate for the construction process. Under the NPDES requirements, stormwater pollution prevention plans must be developed that use structural and nonstructural Best Management Practices (BMPs) to obtain reductions in urban pollutant loading to the "maximum extent practicable." BMPs, such as sand bag dikes, temporary desilting basins, and spillways, can reduce impacts during project construction to a level considered less than significant. An erosion control plan would be developed based on the use of temporary onsite detention basins in accordance with requirements of the City of Moorpark and VCFCD. Development activities, including roadways, increase the potential of stormwater runoff transporting surface water quality contaminants from roadway surfaces. Typical urban runoff contaminants can be expected within runoff reaching the Arroyo Simi from local storm channels. The primary pollutants of concern would be the concentration of hydrocarbons, as a result of the proposed roadway and the introduction of vehicular traffic, are expected to increase over background conditions. The roadway's contributions of these pollutants is not expected to have a significant impact above that which was already assumed for the Specific Plan project. The proposed Specific Plan project includes, or has been mitigated, so that it includes programs /measures that are consistent with the water quality policies of the county's 208 Plan. For instance, a comprehensive urban runoff management plan (see Section 3.2, Mitigation Measure 3 of the Hidden Creek Ranch Specific Plan EIR) will be required prior to the approval 2.2 -5 Water Resources Hidden Creek Ranch Speck Plan Spring Road Connection of the Master Tract Map to mitigate for the Specific Plan project's impacts to water quality; this measure would also be applicable to the Spring Road connection. Flooding A Spring Road connection would cross through Flood Zone A within Happy Camp Canyon. The roadway would cross perpendicular to the drainage in Happy Camp Canyon. The city requires at least one dry lane during a 50 -year storm. The roadway would be designed to not impede flows such that vehicular lanes would not be subject to inundation. Groundwater Development of the roadway would not increase impervious surfaces beyond that assumed for the Hidden Creek Ranch Specific Plan project. The major areas of aquifer recharge would not be affected. No significant impacts to recharge are expected. CUMULATIVE IMPACTS No cumulative impacts beyond that assumed for the Specific Plan project would occur. MITIGATION MEASURES No additional mitigation would be required beyond that assumed in the EIR. CONCLUSIONS No new impacts have been identified. 2.2-6 Water Resources Hidden Creek Ranch Specific Plan Spring Road Connection 2.3 BIOLOGICAL RESOURCES METHODS Data regarding biological resources in lower Happy Camp Canyon were obtained through a review of existing literature pertaining to the site and its biological resources, field surveys, and applicable reference materials. Literature Review Information on projects located in the vicinity of Happy Camp Canyon was obtained by Michael Brandman Associates (MBA 1993, 1995, 1996). Field guides and other literature pertinent to the project area were also consulted. Sensitive biological resources present or potentially present in the study area were identified through a literature review using the following sources: U.S. Fish and Wildlife Service (USFWS) (1993, 1994), California Department of Fish and Game (CDFG) (1988, 1990a, 1990b, 1996a, 1996b, and 1996c), California Natural Diversity Data Base (CNDDB) (1992, 1995), and the California Native Plant Society (Skinner and Pavlik 1994). Field Surveys Field surveys were conducted by MBA biologists Cynthia A. Jones, Ruben S. Ramirez, and Keith W. Babcock. The initial survey was conducted on April 2, 1996; additional surveys were conducted on April 15, 23, and May 1, 1996, in conjunction with directed surveys for the federally threatened coastal California gnatcatcher (Polioptila californica califomica) (hereafter referred to as the gnatcatcher). Plant communities were mapped in the field directly onto 200 - scale (1 inch = 200 feet) topographic maps. An 800 -scale color aerial photograph of the study area was also used to aid in vegetation mapping. Plant communities in the study area were identified according to Holland (1986), when possible. Communities not described in Holland were identified using Gray and Bramlet (1992) with additional information provided by other sources. All plant species encountered during the field survey were identified and recorded. Scientific nomenclature and common names of plants used in this report follow Hickman (1993). Where not available in Hickman, common names are taken from Munz (1974) or Abrams (1923 and 1944) and Abrams and Ferris (1951 and 1960). A complete list of the plant species observed in the study area during the surveys is presented in Table 1 of Appendix C. Wildlife species detected during field surveys by sight, calls, tracks, scat, or other sign were recorded. In addition to species actually observed, expected wildlife usage of the site was determined according to known habitat preferences of regional wildlife species and knowledge of their relative distributions in the area. A complete list of wildlife species observed or detected 2.3 -1 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Connection in the study area is presented in Table 2 of Appendix C. Scientific nomenclature and common names for vertebrate species referred to in this report follow Collins (1990) for reptiles and amphibians, American Omithologists' Union (1983, with supplements in 1985, 1987, 1989, 1991, 1993, and 1995) for birds, and Jones et al. (1982) for mammals. Coastal California Gnatcatcher Surveys Focused surveys for the gnatcatcher were conducted by MBA to determine the presence or absence of this species in the study area. All areas of potential gnatcatcher habitat (coastal sage scrub) in the study area were surveyed three times with intervals of one week between surveys, in accordance with Southern California Coastal Sage Scrub Scientific Review Panel (SRP 1992) guidelines. The initial survey was conducted on April 15, 1996. The second survey was conducted on April 23, 1996 and the final survey was conducted on May 1, 1996. Weather conditions during the surveys were conducive to high levels of bird activity. Temperatures were mild, ranging from approximately 65 to 85 degrees Fahrenheit. Wind speed ranged from 0 to 5 miles per hour, with occasional gusts to 10 miles per hour on April 15. Surveys were conducted between 6:30 a.m. and 12:30 p.m. Surveys were conducted by Keith Babcock under U.S. Fish and Wildlife Service Permit Number 782274. Areas of potential gnatcatcher habitat were surveyed on foot by walking along transect routes determined by vegetation and topography. Surveys for gnatcatchers were conducted by using a combination of taped gnatcatcher vocalizations and "pishing" sounds to elicit responses from birds. Calling points were located at intervals of approximately 200 feet. EXISTING CONDITIONS Lower Happy Camp Canyon is located in the low, rolling foothills north of the City of Moorpark in Ventura County. The lower portion of the north -south trending canyon contains wide bands of relatively level terrain bordered by moderate to steeply sloping topography. Vegetation consists of open to dense grassland and scrub vegetation in the floor of the canyon, with sage scrub and isolated trees occurring on the canyon slopes. The floor and hillsides in the lower canyon are underlain by alluvial material. A north -south incised channel occurs in the dry wash through the center of the valley floor within the study area. Elevations range from 750 feet above sea level in the bottom of the canyon to 900 feet above sea level at the top of the canyon slopes to the east and west. 2.3 -2 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Connection Plant Communities Four plant communities were identified as occurring within the project site boundaries: Venturan coastal sage scrub, non - native grassland, southern cactus scrub, and alluvial scrub /non- native grassland. Small clusters and individuals of coast live oak (Quercus agrifolia) occur along the base of both the western and eastern slopes. Exhibit 2.3 -1 shows the locations of the plant communities on the project site. Each of these communities are described below. Venturan Coastal Sage Scrub Venturan coastal sage scrub is typically found on dry, often rocky slopes, below 3,000 feet above sea level. This community ranges from Point Conception south through coastal areas of Ventura and Los Angeles counties and extends inland to Cajon and San Gorgonio passes. Vegetation consists of low- growing shrubs with patches of bare ground beneath the shrubs (Holland 1986). Coastal sage scrub is found on the study area on the eastern and western slopes and'ridges of the canyon, with more of this community occurring on the western slopes. Most of the sage scrub on the site is dominated by purple sage (Salvia leucophylla) and California sagebrush (Artemisia califomica). Other shrubs that are common in the coastal sage scrub include California buckwheat (Eriogonum fasciculatum), white sage (Salvia apiana), sacapellote (Acourtia microcephala), deerweed (Lotus scoparius), and coastal prickly pear (Opuntia littoralis). Common herbaceous species include California everlasting (Gnaphalium califomicum), common forget -me -not (Cryptantha intermedia), California popcorn flower (Plagiobothrys collinus), branching phacelia (Phacelia ramosissima), and chaparral nightshade (Solanum xanti). Non - native Grassland Non - native grassland consists of non - native, annual grasses often associated with native annual forbs. These grasses begin to germinate with the fall rains, grow during the winter and spring, and wither in the early summer. This community is often found on clay and sandy soils (Holland 1986). Non - native grassland primarily occurs on the valley floor and in isolated areas on the slopes and ridges on either side of the canyon. This community integrates with coastal sage scrub at the slope bases and with alluvial scrub on the valley floor. The non- native grasslands are dominated by slender wild oat (Avena barbata), wild oat (Avena fatua), ripgut grass (Bromus diandrus), foxtail barley (Hordeum murinum), soft chess (Bromus hordeaceus), and foxtail chess 2.3 -3 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Connection (Bromus madritensis ssp. rubens). Dove weed (Eremocarpus setigerus), a native species, is also common throughout this plant community. These grasslands also include areas dominated by weedy species, including tocalote (Centaurea melitensis), horseweed (Conyza canadensis), black mustard (Brassica nigra), and red - stemmed filaree (Erodium cicutarium). Southern Cactus Scrub Southern cactus scrub is a subassociation of coastal sage scrub. This community generally occurs on south - facing slopes on low foothills and consists of both cacti and coastal sage scrub species (Gray and Bramlet 1992). This plant community is defined as having cactus (Opuntia spp.) providing more than 20 percent of the relative plant cover (Jones and Stokes Associates, Inc. 1992). Southern cactus scrub is dominated by coastal prickly pear, with California buckwheat, California bush sunflower (Encelia califomica), California sagebrush, and bladderpod (lsomeris arborea) also being common. Mexican elderberry (Sambucus mexicana) is present in smaller numbers. Southern cactus scrub is generally found on the site's south- and west - facing slopes and commonly borders or occurs within Venturan coastal sage scrub. Alluvial Scrub /Non- native Grassland Alluvial scrub vegetation is typically found in washes, alluvial fans, and stream beds that receive periodic flooding during the rainy season and are often dry during summer months. These communities are typically found at the mouths of canyons along the coastal side of mountains and in lesser floodplain and riverine locations of southern California. Vegetation typically consists of widely scattered trees or tall shrubs with an understory of sparse shrubs. Plants generally found in coastal sage scrub, chaparral, and desert habitats are also common in this community. Soil stratigraphy in this community consists of active channel, barren cobbles, and vegetated terraces of varying heights and ages (Hanes et al 1988). The vegetation within the alluvial wash in the lower, southern portion of Happy Camp Canyon is disturbed and heavily dominated by non - native grasses. Any native components of an alluvial scrub vegetation community that may have existed at one time has virtually been eliminated. Shrub cover is sparse with scale -broom (Lepidospartum squamatum) being the most common species. This community, while it may have historically contained components of alluvial scrub vegetation, is so invaded by non - native grasses that it has lost most of the qualities and attributes that characterize true alluvial scrub communities. Therefore, this community is more accurately described as being alluvial scrub /non- native grassland. Bladderpod, spiny redberry (Rhamnus crocea), mugwort (Artemesia douglasiana), pectocarya (Pectocarya penicillata), 2.3 -4 Biological Resources Specific Plan No. 2 Legend Vegetation Communities - Alluvial Scrub/Non Native Grassland Coastal Sage Scrub Non Native Grassland Southern Cactus Scrub 0 Proposed Road Alignment Scale 1 inch = 400 feet Hidden Creek Ranch Fic Plan No. S EXHIBIT 2.3 -1 Vegetation Communities Hidden Creek Ranch Specific Plan Spring Road Connection California popcorn flower, and coastal prickly pear are other species commonly found in this community. Non - native grasses, dominated by slender wild oat, ripgut grass, and foxtail barley, and dove weed, are the most common understory species. Wildlife A number of wildlife species were observed, and could potentially occur, within the study area boundaries. These species are discussed below according to taxonomic classification. Amphibians Although the majority of the site is dry for most of the year, there are several amphibians species that occur, or potentially occur, in the study area. Terrestrial amphibians avoid desiccation by burrowing underground, moving into crevices in trees, rocks, and logs, or hiding under stones and surface litter during the heat of the day and dry seasons. Many amphibians are adapted to the arid conditions of the site and can be locally abundant to common in almost all available habitat types. In addition, soil moisture conditions can remain high within habitat types depending on such factors as amount of vegetation cover, elevation, and the aspect of slope. The grassland and scrub communities provide suitable habitat for several species, including the western toad (Bufo boreas), California chorus frog (Pseudacris cadaverina), and Pacific chorus frog (Pseudacris regilla). These species are expected to be the most abundant amphibians on the study area and likely use the incised channel during rain events, and other areas that may briefly hold water, for breeding during the spring and early summer. Species that require a permanent water source are not expected to occur on the roadway alignment study area. Reptiles Reptilian diversity and abundance typically varies with habitat type and character. Many species prefer only one or two plant communities; however, most will forage in a variety of habitat types. Most species occurring in open habitats use rodent burrows for cover and protection from predators and extreme weather conditions. Reptile species observed in the more open grassland and scrub communities on the study area include the side - blotched lizard (Uta stansburiana), western fence lizard (Sceloporus occidentalis), and western rattlesnake (Crotalus viridis). Other species expected to occur include coast homed lizard (Phrynosoma coronatum), coastal western whiptail (Cnemidophorus 2.3 -5 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Connection tigris multiscutatus), California whipsnake (Masticophis lateralis), and gopher snake (Pituophis melanoleucus). These habitats are also expected to support other snake species such as the coachwhip (Masticophis flagellum), coastal rosy boa (Lichanura trivirgata), glossy snake (Arizona elegans), coast patch -nosed snake (Salvadora hexalepis virgultea), common kingsnake (Lampropeltis getulus), and night snake (Hypsiglena torquata). Birds Bird species observed on the site include those species typical of coastal sage scrub (which supports a relatively high diversity of bird species) and grasslands (which typically have a lower diversity of bird species). Most of the birds observed during the surveys are either resident species of the region or summer breeders. Common resident birds observed in the coastal sage scrub include California quail (Callipepla cafifomica), Anna's hummingbird (Calypte anna), bushtit (Psaltriparus minimus), Bewick's wren (Thryomanes bewickit), wrentit (Chamaea fasciata), northern mockingbird (Mimus polyglottos), spotted towhee (Pipilo maculatus), and California towhee (Pipilo crissalis). Other species observed in fewer numbers include the greater roadrunner (Geococcyx califomianus), California thrasher (Toxostoma redivivum), and morning dove (Zenaida macroura). Coastal sage scrub also provides breeding habitat for several summering birds, including Costa's hummingbird (Calypte costa) and lazuli bunting (Passerina amoena). Several other birds including white - crowned sparrow (Zonotrichia leucophrys) and golden - crowned sparrow (Zonotrichia atricapilla) are expected to use the coastal sage scrub during winter months. Most of these birds are just as prevalent in the southern cactus scrub. Cactus wrens (Campylorhynchus brunneicapillus) were commonly observed in the study area in the southern cactus scrub and coastal sage scrub with cactus patches. The grasslands in the study area provide foraging, breeding, and wintering habitat for several bird species. Western meadowlarks (Stema neglecta), a resident species, and grasshopper sparrows (Ammodramus savannarum), a summering species, breed in this habitat. Fences and shrubs near the grassland provide perches that allow summering birds such as western kingbird (Tyrannus verticalis) and Cassin's kingbird (Tyrannus vociferans) to flycatch over the grasslands. Cliff swallows (Hirundo pyrrhonota) and northern rough- winged swallows (Stelgidopteryx serripennis) were observed foraging over the grassland. In winter, Say's phoebe (Sayomis saya), American pipit (Anthus rufescens), and savannah sparrow (Passerculus sandwichensis) are expected to use this habitat. 2.3 -6 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Connection Individual oak trees and oak clusters in the study area provide nesting and foraging sites for western kingbird, Cassin's kingbird, phainopepla (Phainopepla nitens), Nuttall's woodpecker (Picoides nuttallh), and northern flicker (Colaptes auratus), all of which were observed. Birds such as ruby- crowned kinglet (Regulus calendula) and yellow - rumped warbler (Dendroica coronata) are expected to use this habitat during the winter. The grasslands, and to a lesser extent the coastal sage scrub, provide foraging habitat for several species of raptor. Cooper's hawk (Accipiter cooperir), red - tailed hawk (Buteo jamaicensis), red - shouldered hawk (Buteo lineatus), and American kestrel (Falco sparverius) were observed over the study area. Turkey vultures (Cathartes aura) were also observed foraging over the study area and nearby areas. Other raptors expected to use the area for foraging on a year -round basis include white - tailed kite (Elanus leucurus) and golden eagle (Aquila chrysaetos). During the winter months, northern harrier (Circus cyaneus), sharp - shinned hawk (Accipiterstriatus), ferruginous hawk (Buteo regalis), and prairie falcon (Falco mexicanus) may forage over the study area and possibly roost. Some of the oak trees may also provide nest and roost habitat for Cooper's hawk, red - tailed hawk, American kestrel, white - tailed kite, great- horned owl (Bubo virginianus), and barn owl (Tyto alba). Mammals The plant communities on the study area provide suitable habitat for a variety of mammal species. Venturan coastal sage scrub, grasslands, and southern cactus scrub provide both dense cover and foraging opportunities for a number of mammals including the California pocket mouse (Perognathus califomicus), California mouse (Peromyscus califomicus), ornate shrew (Sorex omatus), brush mouse (Peromyscus boylir), California ground squirrel (Spermophilus beechen), desert cottontail (Sylvilagus audubonir), and Bottas's pocket gopher (Thomomys bottae). These in turn provide prey for larger mammals such as grey fox ( Urocyon cinereoargenteus), coyote (Canis latrans), and bobcat (Lynx rufus). American badger (Taxidea taxus) may also occur in these habitats on the study area. Tracks of mule deer (Odocoileus hemionus) were observed in several areas within the coastal sage scrub and grasslands. Common bat species that may forage over these habitats include the western pipistrelle (Pipistrellus hesperus), California myotis ( Myotis califomicus), and big brown bat (Eptesicus fuscus). The areas of coastal sage scrub and grassland that contain oak trees and low shrubs provide suitable foraging and cover habitat for raccoon (Procyon lotor), opossum (Didelphis virginiana), and striped skunk (Mephitis mephitis). 2.3 -7 Biological Resources Hidden Creek Ranch Speck Plan Spring Road Connection Sensitive Biological Resources This section addresses those biological resources known to occur or potentially occurring on the study area or in the vicinity that are given special recognition or status by federal, state, or local conservation agencies and organizations because of declining, limited, or threatened populations and/or ranges of these species. This includes vegetation communities that are considered unique, of relatively limited distribution, or of particular value to wildlife. Only those species or plant communities that are known to occur or have a high potential of occurring on the site are discussed below. Table 2.3 -1 lists all special- status species occurring or potentially occurring on the site or in the project vicinity. Definitions of the various state and federal agency special- status categories are given at the end of this table. Plants No surveys for special- status plant species were conducted for the proposed roadway alignment. However, the area where the roadway could be implemented is within the range of several special- status plant species that are known to occur, or could potentially occur, in the project vicinity (Table 2.3 -1). One special- status species was observed in the study area and three additional species may potentially occur there. These species are discussed below. Catalina mariposa lily (Calochortus catalinae); CNPS List 4. The Catalina mariposa lily is a perennial herb that blooms from February to May. Catalina mariposa lilies require heavy soil and are found in openings of coastal sage scrub, grasslands, chaparral, and woodlands. This species ranges from San Diego County north to San Luis Obispo County at elevations below 2,000 feet above sea level. The Catalina mariposa lily is also found on several of the Channel Islands (Munz 1974). This species has been found in habitats adjacent to both the east and west of Happy Camp Canyon (MBA 1995, 1996) and could potentially occur in suitable habitat in the study area. Western dichondra (Dichondra occidentalis); CNPS List 4. This perennial herb occurs on sandy slopes under trees or shrubs in association with coastal sage scrub, chaparral, and oak woodlands. It blooms from March to May. This species could potentially occur in suitable habitat areas in the study area. 2.3 -8 Biological Resources Hidden Creek Ranch Specific Plan f _ ari g Road Extension TABLE 2.3 -1 SENSITIVE PLANT AND WILDLIFE SPECIES POTENTIALLY OCCURRING IN LOWER HAPPY CAMP CANYON 2.3 -9 Biological Resources USFWS Blooming Project Study Area Species Old /New CDFG CNPS Habitat Life Form Period Occurrence PLANTS Braunton's milkvetch FE -- List 1 B carbonate soils, recently burned perennial March - Carbonate soils in study Astragalus brauntonii areas;

CNPS List 4. This tree species typically occurs on slopes, canyons, and in alluvial areas associated with coastal sage scrub, chaparral, and oak woodlands. The species ranges from Ventura County to westem San Bernardino and Orange counties. This species occurs on the study area in small numbers along the base of the eastern and western slopes of the canyon. California spineflower (Mucronea californica); CNPS List 4. California spineflower is a small, annual herb that blooms from March to August. It is found in dry, sandy places within coastal sage scrub, chaparral, grassland, and woodland habitats. The species ranges from San Luis Obispo County inland to western San Bernardino County and south to San Diego County (Munz 1974). California spineflower has been found in habitats adjacent to the west of Happy Camp Canyon (MBA 1996) and could potentially occur in suitable habitat on the study area. Wildlife Other than for the gnatcatcher, no focused surveys were conducted for special- status wildlife species. The study area is within the range of several special- status wildlife species that are known to occur or could potentially occur in the project vicinity (Table 2.3 -1). Only two special - status species, coastal cactus wren and Southern Califomia rufous- crowned sparrow, were observed during the reconnaissance survey and focused gnatcatcher surveys. Twenty -two additional special- status species may either forage on the site during the winter months or as transients from other areas, or may potentially breed in the study area. These species are discussed below. Reptiles Coast horned lizard (Phrynosoma coronatum); California Species of Special Concem. The coast homed lizard occurs primarily in open or sparse areas of coastal sage scrub, chaparral, grassland, and woodland communities. It particularly prefers dry washes and requires the presence of harvester ants (Pogonomyrmex spp.) as a food source. Coast homed lizards range from the Central Valley and the coast ranges north of San Francisco south to cismontane southern California (Stebbins 1986). Ventura County is considered to be within the zone of integration between two subspecies, the California homed lizard (P.c. frontale) and the San Diego homed lizard (P.c. blainvillei). Both subspecies have the same state status. This species has been observed in habitats adjacent to the east and west of Happy Camp Canyon. Coast homed lizards are likely to occur throughout the study area in all areas of suitable habitat. 2.3 -15 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension Silvery legless lizard (Aniella pulchra pulchra); California Species of Special Concern. This lizard can be found in a variety of habitats, especially where moist loose soils and cover material are available. It ranges from near Antioch, California, south into Baja. This species is known to occur in habitats adjacent to the east of Happy Camp Canyon and may occur in the coastal sage scrub in the study area, especially in areas near trees and other larger shrubs where appropriate microhabitats for this species are present. Coast patch -nosed snake (Salvadora hexalepis virgultea); California Species of Special Concern. This snake can be found in a variety of grassland, chaparral, sage scrub, and woodland habitats. It ranges west of the Mojave desert in southern California from the vicinity of the Carrizo Plain south into Baja. The coast patch -nosed snake may occur in the coastal sage scrub, non - native grassland, or alluvial scrub /non- native grassland habitat in the study area. Birds California horned lark (Eremophila alpestris actia); California Species of Special Concern. This species prefers grasslands and open areas in which to forage and breed. It ranges throughout central and southern California in suitable habitat areas. This species is expected in the study area in suitable habitat areas. Coastal cactus wren (Campylorhynchus brunneicapillus); California Species of Special Concern. The coastal cactus wren is found in cactus dominated coastal sage scrub habitats and ranges from Ventura County south to northwestern Baja California. Happy Camp Canyon lies at the northern limits of this species' range along coastal California. Several coastal cactus wrens were observed in the study area, primarily on the western slopes of the canyon. Coastal California gnatcatcher (Polioptila califomica califomica); Federally Threatened, California Species of Special Concern. This species is a small, non - migratory resident of coastal sage scrub in southern California. It typically prefers sage scrub dominated, or at least co- dominated, by California sagebrush in habitat of at least 5 to 10 acres in size. The present known range of the California gnatcatcher extends from the Palos Verdes peninsula and Montebello in Los Angeles County south through Orange, western Riverside, western San Bernardino and San Diego counties into Baja California. Historically, California gnatcatchers have occurred in the Santa Clara River Valley and in Simi Valley in Ventura County. The last previously confirmed sighting of a California gnatcatcher in Ventura County was in 1924 (Atwood 1993). 2.3 -16 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension Two breeding pairs of California gnatcatchers are known to occur approximately 0.5 mile to the west of Happy Camp Canyon, which represents a northward extension of its current known range (MBA 1996). Most of the habitat on the east side of the canyon is relatively small in size, fragmented, and dominated by purple sage. More suitable gnatcatcher habitat occurs on the western slopes of the canyon, although a majority of the coastal sage scrub habitat on this side of the canyon is still somewhat fragmented and small in size. However, at least two patches of coastal sage scrub habitat contain a large amount of California sagebrush (at least 8 to 10 acres in size). Although, no gnatcatchers were observed during the three surveys conducted in lower Happy Camp Canyon in 1996, California gnatcatchers could potentially occur within suitable habitat in these areas in the future. Loggerhead shrike (Lanus ludovicianus); California Species of Special Concern. This species is found in open woodlands, open shrublands, and grassland habitats. Loggerhead shrikes nest throughout California with the exception of the high Sierra Nevada and the Pacific northwest. This species is expected to occur in the study area in suitable habitat areas. Southern California rufous - crowned sparrow (Aimophila rufrceps canescens); California Species of Special Concern. This subspecies is found in coastal areas from Santa Barbara County south through San Diego County (CDFG 1990a). The Southern California rufous - crowned sparrow prefers somewhat steep areas of coastal scrub and chaparral with a grassy understory. Two individuals of this species were observed in the study area during the gnatcatcher surveys. Bell's sage sparrow (Amphispiza be0i belli); California Species of Special Concern. Bell's sage sparrow ranges from the inner coast ranges of Shasta County south to Marin County where it is then restricted to coastal areas from Mahn County south to San Diego County. Bell's sage sparrow prefers chaparral and coastal sage scrub habitats. This species is a rare and local breeder throughout coastal southern California. This species is expected to occur within the study area in suitable habitat. The site provides both suitable foraging and nesting habitat for the white - tailed kite and Cooper's hawk. The site also provides suitable wintering and foraging (although no nesting) habitat for the northern harrier, sharp- shinned hawk, ferruginous hawk, golden eagle, merlin, prairie falcon, and western burrowing owl. All of the above mentioned raptors are either federally protected and/or California species of Special Concern. 2.3 -17 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension Mammals Pale Big -eared Bat (Plecotus townsendii pallescens); California Species of Special Concern. This species occupies a variety of communities, including oak woodlands, and grasslands, and high elevation forests and meadows. Known roosting sites in California include mines, caves, and buildings. No suitable roosting habitat is present although suitable foraging habitat for this species is present. Pallid Bat (Antrozus pallidus); California Species of Special Concern. This species most commonly occurs in mixed oak and grassland habitats. This large bat roosts in rock crevices and under tree bark. The study area provides suitable foraging and roosting habitat for this species. Spotted Bat (Euderma maculatum); California Species of Special Concern. This species may be considered one of North America's rarest mammals (CDFG 1991). The spotted bat is known to occur in the foothills, mountains, and desert regions of southern California within desert, grassland, and forest habitats. The study area may provide suitable foraging habitat for this species. California Mastiff Bat (Eumops perotis califomicus); California Species of Special Concern. The California mastiff bat is the largest bat in the United States, is a California Species of Special Concern. This species is a very wide- ranging and high -flying predator that typically forages in open areas with high cliffs. It roosts in crevices in small colonies. This species may forage over various habitat types within the study area. San Diego desert woodrat (Neotoma lepida intermedia); California Species of Special Concern. The San Diego desert woodrat prefers open habitats in dry areas. It can be found in Joshua tree and pinon juniper woodlands, chaparral, sagebrush, and most brush- dominated desert habitats. Near the coast, this species favors rocky sage scrub and chaparral habitats. It is found throughout southern California from the desert to the coast. This species is expected to on the study area in suitable habitat areas. San Diego black - tailed jackrabbit (Lepus califomicus bennettit); California Species of Special Concern. This species is typically found at lower elevations in shrub, sage scrub, and chaparral communities, throughout coastal and inland southern California west of the desert. This species is expected to occur on the study area in suitable habitat areas. 2.3 -18 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension Plant Communities Sensitive plant communities are those communities that support concentrations of special- status plant or wildlife species, are of limited distribution, or are of particular value to wildlife. Sensitive plant communities are not afforded legal protection unless they support protected species. Venturan coastal sage scrub is considered sensitive by resource agencies. Southern cactus scrub, a subassociation of Venturan coastal sage scrub, would also be considered sensitive under this classification. In this region of southern California, this vegetation community supports several special- status plant and wildlife species and is continuing to decline throughout its range. The coastal sage scrub on the roadway alignment study area supports at least two special- status bird species, coastal cactus wren and Southern California rufous- crowned sparrow, and could potentially support seven additional special- status wildlife species and three special- status plant species. Alluvial scrub is considered sensitive by resource agencies because of its uniqueness and declining nature. It is traditionally an open vegetation community found on sandy outwash fans deposited by streams that experience infrequent episodes of severe flooding. These communities are typically found at the mouths of canyons along the coastal side of mountains and lesser floodplain and riverine locations of southern California. As described earlier, the alluvial scrub /non- native grassland found on the study area is disturbed and dominated by non - native grasses. Virtually all of the qualities and attributes that characterize true alluvial scrub communities have been eliminated from the alluvial wash area; very few vegetative components of alluvial scrub remain. Therefore, the alluvial scrub /non- native grassland community presently occurring on the study area is not considered a sensitive resource. Wildlife Movement Corridors Wildlife movement corridors link together areas of suitable wildlife habitat that are otherwise separated by rugged terrain, changes in vegetation, or by human disturbance. The fragmentation of wildlife habitat by urbanization creates isolated "islands" of wildlife habitat. In the absence of habitat linkages that allow movement to adjoining open space areas, some wildlife species, especially larger and more mobile mammals, will not likely persist over time in fragmented or isolated habitat areas because they prohibit the infusion of new individuals and genetic information. Corridors mitigate the effects of this fragmentation by (1) allowing animals to move between remaining habitats which allows depleted populations to be replenished and promotes genetic exchange; (2) providing escape routes from fire, predators, and human 2.3 -19 Biological Resources Hidden Creek Ranch Speck Plan Spring Road Extension disturbances, thus reducing the risk that catastrophic events (such as fire or disease) will result in population or local species extinction; and, (3) serving as travel paths for individual animals as they move within their home ranges in search of food, water, mates, and other needs. Within the Oak Ridge and Big Mountain open space areas within the Santa Susana Mountains, the central and upper portion of Happy Camp Canyon is considered an important travel route by wildlife species moving within home ranges and territories, or dispersing from these areas. The canyon provides suitable food, water, and shelter, as well as little topographical resistance, for a variety of species while moving from one area to another. However, while this canyon does serve as an important travel route for species moving within the Oak Ridge /Big Mountain open space area, it does not serve as a regional wildlife movement corridor, as defined above, that links large open space areas otherwise separated from each other. This is primarily because the southern terminus of the canyon abuts against urban development associated with the City of Moorpark that extends to the south, east, and west at this point. Wildlife species traveling south along Happy Camp Canyon would eventually arrive at this urban area interface and would not move beyond it. IMPACTS Impacts of the proposed roadway extension on biological resources are discussed below in terms of the amount of vegetation lost or adversely affected by the Spring Road extension. The significance of this loss is determined by the overall value of the vegetation as wildlife habitat, its sensitivity status with state and federal resource agencies, and its ability to support sensitive resources. Impacts are also discussed in terms of the expected direct effects (mortality and/or displacement) of the project on both common and special- status plant and wildlife species occurring, or potentially occurring, on the site. The criteria and thresholds for determining significance of impacts are discussed first. Significance Criteria Significant impacts on biological resources posed by the proposed road across the lower portion of Happy Camp Canyon were determined from criteria stated in the CEQA Statutes and Guidelines. Appendix G of these guidelines states that a project will normally have a significant impact on biological resources if it will: • substantially affect a rare or endangered species of plant or animal or the habitat of such species; 2.3 -20 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension • interfere substantially with the movement of any resident or migratory fish or wildlife species; • substantially diminish habitat for fish, wildlife, or plants; • conflict with adopted environmental plans and goals in the community where it is located; or • involve the use, production, or disposal of materials which pose a hazard to animal or plant populations in the area affected. Section 15065(a) of the CEQA Guidelines also states that a project may have a significant effect on the environment when the project has the potential to: • substantially degrade the quality of the environment, • substantially reduce the habitat of a fish or wildlife species, • cause a fish or wildlife population to drop below self- sustaining levels, • threaten to eliminate a plant or animal community, or • reduce the number or restrict the range of a rare or endangered plant or animal. For the purposes of this report, "rare and endangered" refers to any plant or animal species considered by USFWS or CDFG as a Species of Special Concern, proposed for listing, or currently listed as threatened or endangered. It also refers to any plants listed by the CNPS as a List 1 species. An evaluation of whether an impact on biological resources would be substantial must consider both the resource itself and how that resource fits into a regional or local context. Substantial impacts would be those that would diminish, or result in the loss of, an important biological resource, or those that would obviously conflict with local, state, or federal resource conservation plans, goals, or regulations. Impacts are sometimes locally important but not significant according to CEQA, because although they would result in an adverse alteration of existing conditions, they would not substantially diminish, or result in the permanent loss of, an important resource on a population -wide, or region -wide, basis. VegetationMildlife Habitat The proposed road extension through Happy Camp Canyon Regional Park will result in impacts to three vegetation communities: Venturan coastal sage scrub, non -native grassland, and alluvial/scrub non - native grassland. The potential impacts on these communities are discussed below. No loss of southern cactus scrub will occur, therefore, impacts to this community are not discussed. 2.3 -21 Biological Resources Hidden Creek Ranch Speck Plan Spring Road Extension Venturan Coastal Sage Scrub The proposed alignment will result in the loss of approximately 1.21 acres of Venturan coastal sage scrub. Because coastal sage scrub is considered a sensitive vegetation community by resource agencies and of high value as wildlife habitat, and because the coastal sage scrub on the site potentially supports a number of special- status plant and wildlife species, the loss of coastal sage scrub would be considered a significant impact. Non - native Grassland The proposed alignment will result in the loss of approximately 4.47 acres of non - native grassland. Non - native grasslands are common in the project vicinity and region. The grassland vegetation in the area of the proposed road crossing is very dense and is not expected to support populations of special- status plants or animals. Because this community is fairly common regionally, is not expected to substantially affect a special- status species or its habitat, and because of the relatively low quantity of grassland to be removed, the loss of non - native grassland would not be considered a significant impact. Alluvial Scrub /Non- native Grassland The proposed alignment is expected to result in the loss of approximately 0.26 acre of alluvial scrub /non- native grassland. As previously discussed, this community cannot be accurately described as a true alluvial scrub community which is considered a sensitive plant community by resource agencies. Because the vegetation to be lost is primarily non - native grassland, which is common throughout the region, and because of the relatively small amount that will be impacted, the loss of alluvial scrub /non- native grassland would not be considered a significant impact. Wildlife In addition to the loss of habitat, the proposed road crossing will displace wildlife species inhabiting the proposed impact areas into similar adjacent habitats, thus increasing competition for available resources in those areas. Animals with low mobility, such as amphibians, reptiles, and small mammals, may be destroyed during project construction activities. However, because of the small amount of habitat that will be removed and the low number of animals that V be either directly or indirectly impacted, the proposed project is not considered to have a subs:. tial impact on wildlife habitat or cause a wildlife population to drop below self- sustaining levels; therefore, impacts on wildlife would not be considered a significant impact. 2.3 -22 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension However, bird nests with eggs or young are protected under the federal Migratory Bird Treaty Act and the California Fish and Game Code. The loss of an active bird nest as a result of construction activities would be considered a violation of these laws. Sensitive Biological Resources Special- Status Plants One special- status plant species, the Southern California black walnut, was observed in the project study area, and three additional species may potentially occur there. Each of these species is listed by the CNPS as a List 4 species, which is the lowest sensitivity status given to plant species by the CNPS. No focused plant surveys have been conducted in the portion of the area that will be directly impacted by the proposed road crossings. However, because of the relatively small amount of habitat to be lost, and because of the low sensitivity status of the special- status plants that could potentially occur, any loss of these plants as a result of the construction of the road crossing would not substantially reduce the number, or restrict the range, of these species in the region; therefore, the loss of any of these plants would not be considered a significant impact. Special- Status Animals Twenty-two special- status wildlife species that could potentially occur in the study area are listed as California Species of Special Concern. Two of these species, the coastal cactus wren and Southern California rufous- crowned sparrow, were observed in the impact area. Because implementation of the roadway would not result in the loss of any cactus scrub habitat, no loss of cactus wrens are expected to occur. Most of the highly mobile species (birds and mammals) that could occur within the construction right -of -way are likely to escape direct mortality as a result of construction and grading activities. However, these activities could potentially displace individuals of special- status species potentially occurring in the study area into nearby areas. Because of the low amount of habitat that will be lost, the displacement of any of these species into nearby areas would not substantially affect these species or their habitat and would, therefore, not be considered a significant impact. Species of low mobility, such as the coast homed lizard, silvery legless lizard, and coast patch - nosed snake could be destroyed by construction activities. Each of these species are listed as Species of Special Concern by CDFG. Therefore, because the project could potentially reduce the number of a rare or endangered species, the loss of any of these species would be considered a significant impact. 2.3 -23 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension resource agencies and jurisdictions); (2) the quantity and species of plants to be planted; (3) planting procedures; (4) a schedule and action plan to maintain the plantings; and (5) a list of criteria by which to measure success of the plantings, as well as contingency measures if the plantings are not successful. S cial- Status Species Birds As a result of construction and grading activities, nests of special- status bird which contain eggs or young could be destroyed if construction occurred during the breeding season. 2. Prior to construction activities that would occur during the breeding season for most birds potentially nesting in the area around the Spring Road extension through Happy Camp Canyon Regional Park (March 1 through July 30), a survey shall be conducted by a qualified biologist to determine if active bird nests are present in the construction zone or within 50 feet of the construction zone. If active nests are found, a 50 -foot fence barrier shall be erected around the nest site and no construction activities within this nest zone will be permitted until the young birds have fledged, as determined by the project biologist. 3. Focused surveys for the coastal California gnatcatcher shall be conducted by a permitted biologist on the site between January 1 and May 1, prior to any grading or construction activities associated with the Spring Road extension through Happy Camp Canyon Regional Park. If the gnatcatcher is found within or immediately adjacent to the impact area of the project, the US Fish and Wildlife Service and California Department of Fish and Game shall be contacted to develop appropriate avoidance and /or protection measure to limit disturbance to the gnatcatcher. Reptiles Construction activities could potentially result in the direct mortality of three special- status reptile species. 4. Immediately prior to construction or grading activities, a survey shall be conducted by a qualified biologist to determine if any of these special- status reptile species are residing within the Spring Road extension roadway right -of -way through Happy Camp Canyon Regional Park. Any of these species that are found shall be relocated to other suitable habitat areas in the Happy Camp Canyon. During construction activities, a biologist will be present on the site to monitor these activities to ensure that none of these species have moved into the construction right -of -way. Individuals of these species that are found during this monitoring period will be relocated to other suitable areas within the canyon. 2.3 -25 Biological Resources Hidden Creek Ranch Specific Plan Spring Road Extension CONCLUSIONS This roadway alternative will not result in any new significant biological impacts that cannot be mitigated to a level that is considered less than significant. 2.3 -26 Biological Resources APPENDIX B Hidden Creek Ranch Speck Plan Spring Road Connection 2.4 LAND USE The following discussion summarizes those portions of the Hidden Creek Ranch Speck Plan EIR, Section 3.4, Land Use and Related Planning Programs, as it pertains to the proposed extension of Spring Road through Happy Camp Canyon Regional Park from the Specific Plan No. 8 site to the Specific Plan No. 2 site. Please refer to the Hidden Creek Ranch Spec Plan EIR, Volumes I through V, for an expanded analysis of land use. EXISTING CONDITIONS Onsite Land Uses • North: Undeveloped open space • South: City of Moorpark residential communities and State Route 118 • East: Proposed Hidden Creek Ranch Specific Plan development • West: Proposed Specific Plan No. 2 development Related Planning Programs City of Moorpark General Plan The study area is located within the City of Moorpark's Area of Interest. The Moorpark General Plan contains the following elements: Land Use; Housing; Circulation; Safety; Noise; and, Open Space, Conservation, and Recreation. Land Use Element The focus of the Moorpark Land Use Element (May 1992) is to establish criteria and standards for land use development, including population and building densities and intensities, within existing city limits and the unincorporated areas immediately surrounding the city int he the city's Area of Interest. Land use categories are used in the Land Use Element to depict the general distribution, location, and extent of public and private use of land. In accomplishing this primary purpose, the Land Use Element fulfills the requirements of Section 65302(a) of the California Government Code, which establishes it as a mandated element of a general pin. The study area is designated Open Space. Goals of the Land Use Element that are applicable to Spring Road are as follows: Goal 12 Ensure that a full range of public facilities and services are provided to meet the needs of the community. 2.4-1 Land Use Hidden Creek Ranch Speck Plan Spring Road Connection Goal 14 Establish land uses and development intensities which are compatible with scenic and natural resources and which encourage environmental preservation. Goal 15 Maintain a high quality environment that contributes to and enhances the quality of life and protects public health, safety and welfare. Goal 16 Enhance and maintain the suburban /rural identify of the community. Goal 17 Enhance the physical and visual image of the community. Housing Element No housing is proposed as a part of the Spring Road connection. Residential development associated with the Hidden Creek Ranch Specific Plan project is addressed in the Hidden Creek Ranch Specific Plan EIR. Circulation Element The primary purpose of the City of Moorpark Circulation Element (May 1992) is to "designate a safe and efficient circulation system which promotes the movement of people and goods in and around the City." The element addresses the circulation facilities that are needed to provide adequate roadway capacity, public transit services, and opportunities for alternatives modes of transportation. The Circulation Element contains three plans, Roadway Circulation Plan, Bikeway Plan, and Equestrian Facility Plan. The Roadway Circulation Plan defines a roadway plan as one that "meets the requirements for safe and convenient movement at the development intensity anticipated in the Land Use Element." The city's roadway circulation system includes five categories of roadways: freeway, six -lane arterial, four -lane arterial, rural collector, and local collector. There are no existing public roads through lower Happy Camp Canyon Regional Park. Happy Camp Canyon Road is an existing private road providing access to existing residences to the north. Access to this road is from Campus Park Drive (west) through a gated entry. A connection of Spring Road through Happy Camp Canyon Regional Park is not shown on the city's Circulation Element. The extension of Broadway Road through the park is shown on the Circulation Element as a future rural collector. A rural collector is defined as: A two- to four -lane roadway with a typical right -of -way of 70-90 feet and a curb to curb pavement width of 54-64 feet. An upgrade from two to four lanes is to be determined as development occurs in rural areas within the city sphere. 2.42 Land Use Hidden Creek Ranch Specific Plan Spring Road Connection The Circulation Element's policies have been established in order that the goals of the element are implemented through public and private contributions. Goals of the element applicable to the proposed project are as follows; Goal 1 Provide a transportation system that supports the land use plan in the General Plan and provides for the safe and efficient movement of people, goods, and services within, into, out of, and through the City of Moorpark. Goal 2 Provide a circulation system which supports existing, approved and planned land uses throughout the City which maintaining a desired level of service on all streets and at all intersections. Goal Provide a citywide system of safe, efficient and attractive bicycle and pedestrian routes for commuter, school, and recreational use. Goal 7 Develop and encourage a transportation demand management system to assist in mitigating traffic impacts and in maintaining a desired level of service on the circulation system. SaLe-ty Element The City of Moorpark Safety Element (February 1988) discusses liquefaction, flooding, landslide /mudslide hazard areas, expansive soils, dam inundation, fire, and expansive soils. State Government Code section 65302(g) requires general plans to include a safety element for: the protection of the community from any unreasonable risk associated with the effect of seismically inducted surface rupture, groundshaking, ground failure, tsunami, seiche, and dam failure; slope instability leading to mudslides and landslides, subsidence and other geologic hazards... known to the legislative body, flooding, and wildland and urban fires. As such, the basic purpose of the Safety Element is to provide a comprehensive inventory of hazards which affect persons and property in the city and its Area of Interest. Basic hazard considerations as they relate to the Spring Road extension include geologic and seismic hazards, surface runoff, and fire. The element does not include any goals, but does include policies that relate to Spring Road. Liquefaction: "The City should continue to monitor ground water levels in all potential liquefaction areas. If the water levels reach within 40 feet of the surface, the City Engineer shall require appropriate foundation design or other mitigations to alleviate the hazard to large structures as necessary. If the water levels reach within 15 feet of the surface the City Engineer shall require special designs for other structures as necessary.- 2.4-3 Land Use Hidden Creek Ranch Speck Plan Spring Road Connection Flooding: "The best way to minimize the impacts of flooding is to impose land use restraints upon any development within the flood plain or to minimize the hazard by improving the channel to carry the 100 year flood." Noise Element Policies of the Noise Element applicable to Spring Road are as follows: Policy 1 Noise barriers or other noise mitigation techniques should be required in new subdivisions if developed along state highways, city streets, or railroads where a significant impact exists or is projected at nearby noise - sensitive locations. Policy 7 The City should encourage the reduction of noise throughout Moorpark. Ooen Soace. Conservation. and Recreation Element The purpose of the Moorpark General Plan Open Space, Conservation, and Recreation (OSCAR) Element (February 1988) is "to maintain the quality of life for Moorpark residents through rational management of natural resources and open space lands." The element presents the current conditions for air, water, open space, recreation, and energy resources as they relate to the conservation, preservation, and management of resources. The primary purpose for the OSCAR Element is to "ensure that the City's natural resources, open space and potential recreation areas are protected for the benefit of residents." Open space is defined in the element as: ...space that is not built upon, and includes both manmade and natural landscapes. Open space can separate or unify urban functions, activities or areas, depending on how it is designed... open space provides opportunities for resource production, scenic preservation, conservation of natural resources, outdoor recreation, public health and safety and development management and control. The study area is designated as a regional park. Goals of the element applicable to the proposed Spring Road extension through Happy Camp Canyon Regional Park are as follows: Goal 1 Preserve and enhance the unique aesthetic and visual qualifies of Moorpark as a city with scenic topographic features and elements that promote the quality of life that Moorpark citizens pursue. 2.4-4 Land Use Hidden Creek Ranch Specific Plan Spring Road Connection Goal 2 Acquire, provide and maintain public parkland for both passive and active use that is equally accessible to the community on the neighborhood, community and regional basis. Goal 3 Ensure the health, safety and general welfare of the public through designating land uses that will minimize the risk of danger to the public. Goal 4 Preserve and maintain the physical and biological environment from future growth- related degradation. In those areas where degradation is inevitable, ensure the restoration of affected areas. Goal 6 Maintain and enhance the open space and designated nongrowth areas for conservation, agriculture, ranching, recreation, leisure and aesthetic purposes. Goal 7 Protect scenic and recreational resources from adverse impacts resulting from oil exploration or oil drilling. County of Ventura General Plan The Ventura County General Plan (May 1988, as amended) designates the Spring Road study area as Open Space (10 acre'). Open Space is defined as: Any parcel or area of land or water which is essentially unimproved and devoted to an open space use... and which is designated on a local, regional or State open space plan as any of the following. - Open space for the preservation of natural resources... - Open space used for the managed production of resources... - Open space for outdoor recreation... - Open space for public health and safety... - Open spaces to promote the formation and continuation of cohesive communities by defining the boundaries and by helping to prevent urban sprawl... - Open space to promote efficient municipal services and facilities by confining urban development to defined development areas. The county's General Plan definition of Open Space is paraphrased below. According to the county General Plan, land is designated Open Space in order to: a) Preserve natural resources such as plant and animal life and water bodies; b) Allow for the managed production of resources such as forest, agriculture, groundwater recharge areas, and mineral resource areas; 2.4-5 Land Use Hidden Creek Ranch Specific Plan Spring Road Connection c) Accommodate outdoor recreational areas including scenic, historic, and cultural resource areas and access to water bodies; d) Ensure public health and safety by creating areas which require special management or regulation because of hazardous conditions such as earthquake fault zones, floodplains, erosion, or high fire risk; e) Encourage the formation of cohesive communities by defining urban boundaries and helping to prevent urban sprawl; and f) Promote efficient municipal services and facilities by confining urban development to defined development areas. IMPACTS Significance Criteria The proposed Spring Road extension through Happy Camp Canyon Regional Park will result in a significant impact on the environment if: • Compatibility conflicts between onsite and/or offsite land uses are created; • It results in the removal of prime farmland from production. In addition, the project would have a significant impact on agricultural resources if it resulted in the early removal of agricultural land from agricultural preservation status. • It would substantially reduce the amount of available open space in the region; • It would be inconsistent with the goals, objectives, or policies of any local, state, or federal plan or program. Land Use Compatibility Onsite Land Uses As previously discussed, Happy Camp Canyon Regional Park is a county regional passive open space park facility. Although there are no existing land uses in the lower park area, the county has previously contemplated the development of lower Happy Camp Canyon with active recreational uses including golf courses. The connection of Spring Road through the park would not require the relocation of or displace any existing land uses, preclude the ongoing use of the park with passive recreational activities (e.g., hiking, equestrian uses) nor is expected to preclude the county from pursuing active recreational opportunities in the park in the future. 2.4-6 Land Use Hidden Creek Ranch Speck Plan Spring Road Connection Compatibility With Surrounding Offsite Land Uses Land Uses to the North Happy Camp Canyon Regional Park is a 3,600 -acre park facility. The park extends north and est of the study area as natural open space. The Spring Road connection through the lower portion of the park would not affect this open space area. Land Uses to the South Surrounding land uses to the south include residential developments in Moorpark and State Route 118 further to the south. The construction of the Spring Road extension through the park will result in significant environmental impacts. However, these impacts can be mitigated to a level that is considered less than significant and would occur with the implementation of Broadway Road or Spring Road. Existing residences will be approximately 800 to 1,400 feet south of the roadway connection through the park. The two -lane road would connect the Specific Plan No. 8 and Specific Plan No. 2 sites. The City of Moorpark received comments on the Hidden Creek Ranch Specific Plan draft EIR that the development of Broadway Road through Happy Camp Canyon Regional Park is inappropriate. Such comments have also been made by some residents during the Planning Commission and City Council hearings that are located near the proposed alignment through the park. As noted in this study, there are no new significant impacts associated with this altemative roadway differ from the Broadway Road extension or that cannot be mitigated to a level that is considered less than significant. Land Uses to the East The property contiguous to the study area to the east is current undeveloped and is proposed for development as the Hidden Creek Ranch Speck Plan (Speck Plan No. 8) project. The Spring Road connection is being considered by the city to facilitate vehicular access for this project, as well as the Specific Plan No. 2 project. Land Uses to the West The property contiguous to the study area to the west is currently undeveloped and is proposed for development as Specific Plan No. 2 as a predominately residential community. The Specific Plan No. 2 development plan identifies the connection of Spring Road into the project site. 2.4-7 Land Use Hidden Creek Ranch Specific Plan Spring Road Connection Consistency with Plans. Policies. and Programs City of Moorpark General Plan The policies and goals of each element of the City of Moorpark General Plan, relevant to Spring Road, were reviewed. Land Use Element Implementation of the roadway is not considered inconsistent with the city's Land Use element goals. Housing Element Policies of the Housing Element are not applicable to a road. Circulation Element An amendment to the Circulation Element will be required to identify the connection of Spring Road through Happy Camp Canyon Regional Park on the Circulation Map of the element. Upon amendment of the element and mitigation of impacts, the project would be consistent with the Circulation Element. Safft Element All applicable policies of the Safety Element can be implemented through the design and mitigation of potential impacts associated with the Spring Road connection. Noise Element Please refer to Section 2.8, Noise, of this study which addresses potential noise impacts associated with project implementation. No new unmitigable impacts have been identified. Open Space. Conservation. and Recreation (OSCAR) Element Development of the road would not conflict with the policies of the OSCAR Element. 2.48 Land Use Hidden Creek Ranch Speck Plan Spring Road Connection County of Ventura General Plan The Ventura County General Plan designates the study area as Open Space. Should either Broadway Road or Spring Road be extended through Happy Camp Canyon Regional Park, an amendment to the county's General Plan would be required. Volume IV, Responses to Comments, to the Hidden Creek Ranch Specific Plan draft EIR provides an extensive policy analysis of the proposed Specific Plan project as it relates to the policies of the county General Plan. Please refer to Letter 9 of Volume IV. No changes in this analysis is required. Implementation of either Broadway Road or Spring Road is considered generally consistent with applicable county policies. MITIGATION MEASURES Measures to mitigate potential significant impacts are described in this study and the Hidden Creek Ranch Specific Plan EIR. Should the Specific Plan project with the Spring Road connection be approved, the development will be subject to all applicable regulations of the city and county, as well as any other governmental entities, and all such requirements and enactments will, by reference, become conditions of project implementation. CONCLUSIONS The land use findings related to Spring Road through Happy Camp Canyon Regional Park indicate that no new significant land use impacts would occur. 2.4.9 Land Use Hidden Creek Ranch Speck Plan Spring Road Connection 2.5 AESTHETICS The following analysis addresses visual resources from both public and private locations that would view the proposed Spring Road connection through Happy Camp Canyon Regional Park associated with the proposed Hidden Creek Ranch Specific Plan project. EXISTING CONDITIONS Onsite Features The study area is undeveloped and is characterized by flat grass plains and rolling hills with gentle slopes. The floor of lower Happy Camp Canyon is dominated by relatively low growing shrubs and grasses, and 0 to 2 percent slopes. The canyon is bordered to the east and west by relatively moderate slopes characterized by larger shrubs and bushes and sparse trees. Other prominent visual features of the study area include its undeveloped natural character, a stormwater drainage channel running in an east/west direction through the extreme southern portion of the park, and mature trees scattered along the canyon hillsides. Happy Camp Canyon Road, a private paved access road, traverses the canyon in a generally northwesterly direction along the eastern edge of the canyon floor. Unpaved access roads that traverse the canyon are also visible from various vantage points. Views from Surrounding Areas This visual analysis has been conducted from several viewpoints within the Moorpark area that are considered sensitive because of their location or type of use. This analysis focuses on the potential visual impacts from these viewpoints if the roadway were to be implemented. The perspectives include views from Happy Camp Canyon Regional Park, the south entrance to the park at the terminus of Campus Park Drive (west), and the rear of residential lots that overlook the study area on the north side of Cambridge Street and the east and north sides of Hastings Street adjacent to the study area. Four viewpoints were selected as representative locations based on the site's visibility from offsite locations (both public and private). The locations used in this analysis are depicted in Exhibit 2.5 -1. Exhibits 2.5-2 and 2.5 -3 provide views of the site in its present condition. The following narratively discusses the vistas these viewpoints provide. 2.5-1 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection Viewpoint A: Views of the proposed roadway alignment from Happy Camp Canyon Regional Park (Exhibit 2.5 -2) This viewpoint looks south across Happy Camp Canyon Regional Park and the proposed roadway alignment from a location on Happy Camp Canyon Road approximately 900 feet north of the terminus of Campus Park Drive. As shown in the photograph, the most prominent foreground feature from this viewpoint is Happy Camp Canyon Regional Park. This area of the park is relatively flat, natural terrain with scrub (the dominant natural vegetation community) and grass vegetation providing ground cover. Middleground views consist primarily of grassland and patches of scrub vegetation. A residential area including mature trees and the backs of homes along the north side of Cambridge Street and the east side of Hastings Street, as well as ridgelines characteristic of this portion of Ventura County, comprise a majority of the background views from this viewpoint. Viewpoint B: Views of the proposed roadway alignment from the northern terminus of Campus Park Drive (west) (Exhibit 2.5 -2) This viewpoint looks north /northwest across the proposed roadway alignment from the southeastemmost portion of Happy Camp Canyon Regional Park. The most prominent foreground and middleground feature from this viewpoint is the flat grassland and scrub -like vegetation characteristic of the study area. Background views to the east include rolling hills and Happy Camp Canyon Road. Distant views include the ridgeline of Big Mountain. Viewpoint C: Views of the proposed roadway alignment from the backs of residences on the north side of Cambridge Street (Exhibit 2.5 -3) This viewpoint looks northeast across the Happy Camp Canyon Channel at the park from a footpath immediately adjacent to the backyard of a residence on the north side of Cambridge Street. The most prominent foreground feature is the earthen and riprap trapezoidal channel. The most prominent middleground feature from this viewpoint is a characteristically flat, grassy portion of Happy Camp Canyon Regional Park. Steep and moderate slopes are visible in the background from this viewpoint. Viewpoint D: Views of the proposed roadway alignment from the backs of residences on the east side of Hastings Street, on the western edge of lower Happy Camp Canyon (Exhibit 2.5 -3) This viewpoint looks north /northeast over the study area from a location immediately adjacent to the College Heights residential development which is situated on the western edge of Happy Camp Canyon to the south of the site.

Middleground views contain the flat grassland of the study area, some small trees, and various shrubs. Similar features are visible in the background, in addition to small canyons, a grove of trees, and the steep ridgeline of Big Mountain. Scenic Corridors /Highways The relationship of the proposed project to planned scenic highways is described below. The City of Moorpark General Plan Open Space, Conservation, and Recreation (OSCAR) Element identifies three scenic corridors in the vicinity of the study area: State Route 118 (SR -118), State Route 23 (SR -23), and the extension of Happy Camp Canyon Road through Happy Camp Canyon Regional Park. The OSCAR Element describes scenic corridors and trails as providing "critical links between open space resources, recreational areas, residential development, and downtown activity centers. Moreover, trails and scenic roadways serve as gateways to the City." With the objective of preserving the scenic quality of transportation facilities, the County of Ventura's Resources Element (CVCRE) also designates SR -118 as an eligible state scenic highway and SR -23 as an eligible county scenic highway. Recreational Areas Existing and planned recreational areas and facilities in the vicinity of the proposed roadway extension study area are described below. As indicated in the city's OSCAR Element, a 3,700 -acre regional recreational facility, Happy Camp Canyon Regional Park, surrounds the proposed alignment of the Spring Road extension through the park. Because of its proximity to the city, this facility is considered to be the primary regional park serving the city's residents. While this park is dedicated to the county and is operating in accordance with its regional park status, a number of ancillary facilities could be constructed in the future. The county General Services Agency continues to consider development within the southern approximately 700 acres of the park. Previously contemplated development by the county in the park include one or two golf courses, parking area, trail heads, concession stands, golf clubhouse, and trails. The northern 3,000 acres is expected to be retained in a natural state and would continue to be used for passive recreational uses, such as hiking, biking, equestrian, and camping. 2.5-3 Aesthetics Hidden Creek Ranch Speck Plan Spring Road Connection The city's OSCAR Element also identifies that the largest single source related to recreation in the city is the surrounding hills and mountains such as those that surround the study area. It is these open space areas that provide the widest variety of recreation opportunities, such as hiking and equestrian trails. According to the city, "these areas enhance the usage of all facilities, preserve natural biotic communities," and "contribute to the natural beauty of Moorpark." Figure 4 (Scenic Pathways and Trails) in the OSCAR Element identifies bike paths, scenic routes, and bike route or trails that traverse the study area. Figure 4 of the city's Circulation Element also identifies the location of equestrian trails that extend through the roadway study area. Light and Glare Presently, no light or glare is generated from the study area. Offsite, residential uses to the south and southwest of the study area generate light from street and residential outdoor lighting. Glare is very limited in that most uses in the area are not constructed with reflective materials. IMPACTS Significance Criteria For the purpose of this analysis, an impact on the visual and aesthetic nature of the area is considered to have a significant impact on the environment if it will: • Substantially alter the existing visual character of the area or any designated scenic viewshed or recreational areatfacility. • Substantially alter public and private views. • Obstruct an existing public scenic vista or view from a designated scenic corridor /highway. • Be inconsistent with the city's Community Appearance Policies, and the County's "Scenic Highway Area" objectives contained in the Ventura County Resources Element. ImRActs to Onsite Features A Spring Road connection through lower Happy Camp Canyon Regional Park would alter the visual characteristics of the park. Grading activities would affect approximately six acres of the 3,700 -acre regional park. During the grading phase, large construction vehicles would be visible from adjacent (and some distant) vantage points, although the canyon walls act as a natural barrier to views from portions of the city located to the east and west, and distant north and 2.5-4 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection south. Since the majority of the study area is extremely flat, minimal grading will be necessary for much of the proposed roadway. The alignment never exceeds a grade of three percent except along the western Happy Camp Canyon wall, where the roadway grade would be approximately 3.7 percent, and along the westernmost ridge of the study area, where the roadway grade would be approximately 4.5 percent. Grading adjacent to the proposed roadway would result in slopes varying from a 2:1 to a 4:1 ratio. The boundaries of grading would not extend more than 150 feet beyond either side of the road except at the crossing of the proposed roadway and Happy Camp Canyon Road, where grading continues along Happy Camp Canyon Road for no more than 600 feet from the crossing. Since only minimal grading will be necessary, this short-term impact to potential viewers of the roadway resulting from grading would be less than significant and no greater than impacts associated with a Broadway Road extension through the park. Views of the proposed roadway from residences on the north side of Cambridge Street are partially obstructed by a 5- foot -tall block wall adjacent to the northern boundary of the residential lots. Due to the flat slopes of canyon floor and the fact that no portion of the proposed roadway will be located more than 1,400 feet directly north from any homes on the north side of Cambridge Road, the impacts on these residences will be lessened. The proposed roadway, however, would be visible from some back porches and elevated backyard structures, as well as from inside some residences. The proposed roadway would also be visible from residences on the east and north sides of Hastings Street. Views from some residences on the north side of Hastings Street would include most of the proposed roadway. Residents residing on the north side of Cambridge Street and the east and north sides of Hastings Street may perceive the implementation of the roadway as a significant impact. Users of Happy Camp Canyon Regional Park both within and outside the study area would be able to see the proposed roadway from many viewpoints. Portions of the proposed roadway behind the western edge of Happy Camp Canyon would not be visible to park users. Some urban characteristics are currently visible from the park. Park users looking south toward the proposed roadway site currently view houses, street lighting, block walls, non - native mature trees (urban landscaping), and other structures. Therefore, in some respects the addition of the proposed roadway would be consistent with the current view. However, urban characteristics are not currently visible to park users looking north toward the proposed roadway site from the extreme southern portion of the park. Park users using Happy Camp Canyon Road would cross the proposed roadway via a controlled stop or a pedestrian crossing under the proposed roadway. Since the proposed roadway alters the natural character of the park in the flat southern portion of the park, this impact may be considered significant by park users. 2.5-5 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection Impacts on Surrounding Views The following is a discussion of each of the viewpoints identified above. Viewpoint A: Views of the proposed roadway alignment from Happy Camp Canyon Regional Park (Exhibit 2.5 -2) Exhibit 2.5 -2 illustrates the views from Happy Camp Canyon Regional Park to the north of the proposed roadway alignment. The viewpoint is taken from the existing Happy Camp Canyon Road. Since the canyon floor is flat, views of the proposed roadway would be relatively unobstructed. Urban structures are visible from this viewpoint in the distance; the proposed roadway would be consistent with the urban backdrop. The view from this point may be different in the future independent of the implementation of the proposed roadway. Happy Camp Canyon Regional Park is a county- maintained recreational facility has been considered for recreational development by the county. The southern portion of the park, where this viewpoint is located, has been previously proposed for golf courses, parking areas, trail heads, and concession areas. As a result, the character of the southern portion of the canyon would be altered if this portion of the park were developed by the county. The effect of this change on the visual impacts of the proposed roadway would be to lessen the severity of impacts. For example, recreational development in the park, should it occur in the future, would need vehicular access and change the character of the park. Viewpoint B: Views of the proposed roadway alignment from the northern terminus of Campus Park Drive (Exhibit 2.5 -2) Exhibit 2.5 -2 illustrates the views from the extreme southeast corner of Happy Camp Canyon Regional Park. The proposed roadway would be visible in the middleground of this view. This viewpoint reflects the view of a park user entering Happy Camp Canyon Regional Park from the southern entrance. With the exception of the paved access road, this view depicts no other developed uses/infrastructure. The road would bisect this view, perhaps giving the illusion that the park begins on the other side of the proposed roadway. As with Viewpoint A, the view from this point would be different in the future if recreational development occurs in the southern portion of the park. If this were to occur, this view would likely include structures, automobiles, golf course users, and landscaping. Construction of a golf course and/or recreational uses by the county would increase the compatibility of the roadway with surrounding uses because such structures are characteristic of developed settings. 2.5-6 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection Viewpoint C: Views of the proposed roadway alignment from the back of a residence on the north side of Cambridge Street (Exhibit 2.5 -3) Exhibit 2.5 -3 illustrates views from residences on the north side of Cambridge Street immediately south of the study area. The proposed roadway would run through the middleground of this view, parallel to the drainage channel. A 5- foot -tall block wall partially obstructs views from these residences. While no urban structures are visible from this viewpoint, tire tracks, debris, and the riprap channel lining can be seen. Viewpoint D: Views of the proposed roadway alignment from the back of a residence on the east side of Hastings Street, on the western end of Happy Camp Canyon (Exhibit 2.5- 3) Exhibit 2.5 -3 illustrates views from residences on the east side of Hastings Street, situated to the southwest of the park, on a ridge that overlooks the study area. The proposed roadway would run through the middleground of this view, descending the westernmost slope and extending toward the grove of low- growing trees in the background of the eastern portion of this view. Only the residential wall displays urban characteristics from this view. The proposed roadway would bisect this view. As with viewpoints A, B, and C, at some point in the future should the county develop recreational uses in the southern portion of the park, this change in use would also contribute to the alteration of the view. Scenic Corridors /Highways and Recreational Areas As indicated previously, the City of Moorpark OSCAR Element identifies three scenic corridors in the vicinity of the study area: SR -118, SR -23, and the extension of Happy Camp Canyon Road through Happy Camp Canyon Regional Park. In addition, the Ventura County Resources Element (VCRE) classifies SR -118 as an eligible state scenic highway and SR -23 as an eligible county scenic highway. According to the VCRE, the first objective in protecting the scenic qualities of county scenic highways is the identification of the scenic corridor. Scenic corridors are defined as "that visible area outside of the highway right -of -way, that can generally be defined as the view from the road" within one - half -mile on either side. The procedure for achieving state designation of scenic highways requires that a local jurisdiction(s) prepare and adopt a program to protect-and enhance the appearance of the "scenic corridor." Based on the definition of a scenic corridor (i.e., within one - half -mile on either side of the roadway), the entire study area is outside of the potential corridors for SR -23 and SR -118. Moreover, views from these roadways would not be impacted. 2.5-7 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection The other scenic corridor and recreational area is Happy Camp Canyon Road /Happy Camp Canyon Regional Park. The proposed Spring Road extension would cross this road alignment. The proposed roadway would be visible to park users in the study area. Views of the proposed roadway from within the park could be mitigated by median and right -of -way landscaping, as well as using street lighting characteristic of rural environments. Although implementation of the Spring Road extension would result in an aesthetic change, it would not significantly impact the scenic corridor associated with Happy Camp Canyon Road through the park. As indicated previously, the OSCAR Element identifies the surrounding hills and mountains that provide hiking and equestrian opportunities including bike paths, scenic routes, and bike routes or trails as the single most important recreational resource within the city. Views from these trails in the hills within Happy Camp Canyon Regional Park are anticipated to be altered. Consequently, users of recreational resources within the park may perceive the inclusion of the roadway as aesthetically obtrusive although the roadway will not limit or prohibit the use of existing recreational opportunities within the park. Light and Glare Implementation of the proposed roadway would introduce new light sources into the project study area. New light sources are anticipated to occur from street and vehicle lights. General increases in light could be expected to incrementally affect the ambient evening light level in and around the proposed roadway. The distance and low magnitude of light increases would not significantly affect nighttime operations at the Moorpark College observatory which is located atop a bluff in the eastern portion of the campus. Light for the roadway from light standards and vehicle lights may have the potential to "spill over" into Happy Camp Canyon Regional Park and may after the wilderness character of the area. However, the park is only intended to operate from sunrise to sunset. Since street and vehicle lights are generally generated from sunset to sunrise, the operating hours of the park preclude light and glare impacts to park users. Residential uses adjacent to the study area would be sensitive to this increase in light. Setbacks and standard mitigation (shielding of lights, increased distance between light standards, etc.) would reduce potential impacts to these uses. Due to the close proximity of the park to residential uses, there is a potential to create an annoyance to adjacent residences. This change may be considered by adjacent residents as significant. 2.5-8 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection CUMULATIVE IMPACTS The cumulative study area for visual impacts related to the projects is defined as the valley and adjacent hillsides. From Viewpoints A, B, C, and D, the visual impacts of the proposed roadway alignment would incrementally add to the amount of visible developed areas in the hillsides surrounding the study area. Due to the visible changes from these locations, the cumulative impacts would be considered significant. Incorporation of project -level mitigation measures would reduce the adversity of impacts to a level considered less than significant. Two residential projects (Specific Plan No. 8 and Specific Plan No. 2) and recreational uses (by the county in the park) have been contemplated adjacent totwithin the study area. The proposed roadway is designed to serve Specific Plan Nos. 2 and 8. If any of these projects are approved, the character of the area will be transformed from open space to urban uses. The proposed roadway would contribute to such a change in the overall character of this portion of the city. However, this change is anticipated in the City of Moorpark General Plan, and would be accomplished to a greater extent by surrounding developments than by the proposed roadway itself. The long -term aesthetic impacts associated with implementation of the proposed roadway generally include the transformation of visual qualities of natural open space areas to a developed area. Although many aesthetic resources in the vicinity of the proposed roadway have been designated for retention as scenic or recreation facilities, open space areas in the study area are likely to develop as the regional population expands. The option of directing growth toward existing urban centers could potentially reduce this impact. The proposed project would contribute to the current trend of new development within the City of Moorpark expanding into undeveloped peripheral areas of the city and its Area of Interest. The implementation of the proposed roadway would result in increases in ambient light levels through the introduction of new light sources. Mitigation measures designed to lessen light impacts are only feasible to the extent that safety levels on the proposed roadway are not jeopardized. Overall, the project would incrementally increase nighttime lighting in the Moorpark area. As future projects are proposed, each is subject to separate environmental review by the City of Moorpark and County of Ventura. 2.5-9 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection MITIGATION MEASURES Prior to the approval of any final subdivision map(s) inclusive of the Spring Road extension, a detailed landscape plan shall be reviewed and approved by the City of Moorpark Community Development Department and County of Ventura. The plan shall be prepared and certified by a licensed landscape architect, with expertise in native plant materials and habitat restoration, taking into account approved planning units, Community Development standard plans, adopted planned community regulations, scenic corridor /resource requirements, and Standard Conditions of Approval. Appropriate landscaping shall be required along the proposed roadway so that medians and manufactured slopes blend into surrounding natural vegetation. 2. During construction of Spring Road, any concrete structures, such as curbs, located in natural areas shall be constructed by the Master Builder with colored concrete (e.g., Omaha Tan) to blend with the surrounding terrain. 3. To the extent allowable by other agencies, all infrastructure associated with the Spring Road extension shall be placed below grade to avoid visually prominent facilities, should there be any. 4. In conjunction with review of the lighting plans for the Spring Road extension, attention shall be given to the need to avoid or minimizing lighting glare and "spill- over" effects. CONCLUSIONS Implementation of suggested mitigation would reduce project - speck and the project's contribution to cumulative impacts to a level that is considered less than significant. 2.5-10 Aesthetics Hidden Creek Ranch Specific Plan Spring Road Connection 2.6 TRANSPORTATION AND CIRCULATION INTRODUCTION AND METHODOLOGY The Transportation and Circulation section of the Hidden Creek Ranch Specific Plan EIR was prepared by Associated Transportation Engineers (ATE). The following discussion addresses only the changes that would occur associated with the extension of Spring Road through lower Happy Camp Canyon Regional Park. Study. Methodologies Traffic Volume Forecasts Traffic volumes for the various land use and circulation system scenarios analyzed were forecast using the Moorpark Traffic Analysis Model (MTAM). A comprehensive traffic model update and calibration was performed as part of the Hidden Creek Ranch Speck Plan project and is described in the MTAM document.' The MTAM is a sub -area (sub - model) derivation of the Ventura Countywide Traffic Model (VCTM) prepared and maintained by the Ventura County Transportation Commission (VCTC). The MTAM is intended to be used as a forecasting tool for a variety of traffic studies and to provide consistency with the forecasting requirements of the Ventura County Congestion Management Program (CMP). The model covers the City of Moorpark as well as adjacent unincorporated portions in the County of Ventura. Circulation System Development The "minimum" circulation system that would meet the city's level of service (LOS) C performance objective for intersection operations was used as a basis for project impact analysis. The determination of the minimum circulation system began by selecting the most likely circulation system components that would be constructed as a result of the development of parcels within the city and its Area of Interest. The next step was to add some of the Circulation Element components (with some modification of size, as appropriate) that appeared to be reasonable with respect to location and cost. This process lead to the development of the circulation systems required to accommodate the year 2000 and year 2010 traffic demands (without the Specific Plan project), respectively. Moorpark Traffic Analysis Model -Model Description and Validation, Austin -Foust Associates, June 1994. 2.6-1 Transportation and Circulation Hidden Creek Ranch Specific Plan Spring Road Connection Study Scenarios The scenarios chosen by the city for the draft EIR analysis were years 2000 and 2010 (General Plan buildout). The study approach was to add to the existing street system the Circulation Element components associated with the development that was projected for year 2000. This land use and street system was then analyzed for year 2000 without the proposed Specific Plan project (No Project scenario); the improvements required to maintain LOS C were identified. The Specific Plan project's land use and street system in year 2000 was then added to the traffic model. For the Year 2010 (No Project) scenario, additional land use and circulation components were added to the Year 2000 (Improved) circulation system. This scenario was then analyzed and the improvements were identified that would provide the desired level of service. Again, there are different improvements that will attain the desired level of service. For the Year 2010 (With Specific Plan Project) scenario, the Year 2000 With Project and improvements was used as the base and the balance of the project added to the model (Hidden Creek development post- 2000). EXISTING CONDITIONS Traffic Study Area The existing roadway circulation system serving the Hidden Creek Specific Plan site includes two state highways, major arterials and local collector streets. Roadways within the study area are described in the Hidden Creek Ranch Specific Plan EIR. Existing Average Daily Traffic Volumes and Existing Peak Hour Traffic Volumes/Levels of Service Existing average daily traffic (ADT) volume data for the traffic study area surface streets were collected by ATE during November /December 1993 and January 1994. Existing ADT volumes on SR -118 and SR -23 were obtained from the City of Moorpark Traffic Analysis Model (MTAM) document. Supplemental traffic data for the Collins Drive /Campus intersection was conducted by Austin -Foust Associates, Inc. in January 1997 and August/September 1997. To estimate the existing operational efficiency of the signalized intersections, an Intersection Capacity Utilization (ICU) analysis was performed in accordance with traffic guidelines published by the City of Moorpark. The existing levels of service for the stop sign - controlled Princeton Avenue /Campus Park Drive intersection were determined based on actual vehicle delays measured during the peak hour periods. The existing levels of service for the Collins Drive /SR- 2.6-2 Transportation and Circulation Hidden Creek Ranch Speck Plan Spring Road Connection 118 eastbound ramps /Los Angeles Avenue intersection were calculated using the theoretical capacity of a three -way stop sign - controlled intersection outlined in the 1985 Highway Capacity Manual. The vehicle delays at the Happy Camp Road/Walnut Canyon Road - Broadway (SR -23) intersections (three separate intersections) were averaged to represent the operations of a single intersection. Please refer to Table 2.6 -1, and to Section 3.6, Transportation and Circulation, of the Hidden Creek Ranch Specific Plan EIR, regarding the findings of these analyses. Data presented in Table 2.6 -1 indicate that all of the traffic study intersections currently operate at acceptable levels of service. This conclusion is based on the City of Moorpark system performance objective of LOS C or better. Field observations conducted by ATE personnel, as well as Austin -Foust Associates, Inc. for the Collins /Campus intersection, confirmed that the study intersections currently operate at acceptable levels of service.

The City of Moorpark significance criteria (City of Moorpark, Guidelines for Preparing Traffic and Circulation Studies) state that if a LOS degradation of one LOS or greater is attributable to a project, it will be considered significant enough to require mitigation. The criteria also states that a LOS degradation of less than one LOS may also be considered significant, depending on circumstances. As a design constraint, it is intended that LOS C or better be maintained. Year 2000 No Seecific Plan or Spring Road Analysis The findings of the traffic analysis in the Hidden Creek Ranch Specific Plan EIR are as follows: The following improvements will be required at the locations expected to exceed the City of Moorpark LOS C or better performance objective under the year 2000 No Project scenario traffic conditions. These improvements will provide the minimum circulation system to operate LOS C or better for the year 2000 No Project scenario. Intersection levels of service are identified in Table 2.6-2. It is assumed that other development in the city, besides the proposed project, or the city itself, would be responsible for implementing these improvements. Los Angeles Avenue /Spring Road. The northbound left-turn movement forecast during the p.m. peak hour period will require the addition of a second northbound left -turn lane; the p.m. peak hour intersection operation will improve to LOS C. This improvement could be implemented by restriping the existing number one northbound through lane to a northbound left-turn lane to provide dual left-tum lanes, one through lane, and a right -turn lane on the northbound approach at this intersection. Modifications to the north -south left-turn signal phasing may be required at this location to avoid potential conflicts between these two movements. • Los Angeles Avenue/Tierra Rejada Road. The westbound left-turn movement forecast during the p.m. peak hour period will require the addition of a second westbound left- turn lane. With this additional turn lane the intersection operation during the p.m. peak hour will improve to LOS C. This improvement could be implemented by restriping the east and westbound approaches at this location. 2.6-4 Transportation and Circulation Hidden Creek Ranch Specific Plan Spring Road Connection TABLE 2.6 -2 YEAR 2000 NO SPECIFIC PLAN OR SPRING ROAD CONNECTION PROJECT PEAK HOUR LEVELS OF SERVICE Table 2.6 -3 summarizes the levels of service associated with the following needed improvements.

Land Use and Traffic Volumes Traffic volumes expected to be generated by the Specific Plan project, for the year 2000 traffic scenario, were added to the year 2000 No Project traffic scenario. These volumes were distributed and assigned to the year 2000 minimum circulation system using the MTAM. As previously noted, a certain amount of project trips will interact within the Specific Plan project boundaries (approximately 15 percent). The year 2000 Proposed Project scenario ADT volumes are depicted in Exhibit 2.6 -1. Levels of Service The a.m. and p.m. peak hour intersection levels of service were recalculated. The level of service worksheets are contained in Appendix D. With the Spring Road connection, two new intersections would be affected by the proposed Hidden Creek Ranch Specific Plan project, Moorpark Avenue/High Street and High Street/Spring Road. Only the intersection of Moorpark Avenue/High Street would operate at an unacceptable level of service (ICU of 0.81 in the p.m. peak hour/LOS D). During the a.m. peak hour, Moorpark Avenue/High Street and during the a.m. and p.m. peak hours, High Street/Spring Road will operate at acceptable levels of service. The intersection deficiency at Moorpark Avenue /High Street can be corrected by the installation of dual left -turn lanes southbound on Moorpark Avenue. However, the Year 2000 scenario does not include the connection between Walnut Canyon Road and Spring Road that would be constructed as part of the proposed Specific Plan No. 2 project. The construction of this roadway link would reduce the traffic volume at this intersection resulting in an acceptable level of service. Construction of this roadway link would preclude the need for the dual left -turn lanes. Year 2010 No Project Analysis In order to determine the traffic impact of the Speck Plan project, a year 2010 No Project cumulative growth baseline traffic scenario was developed to which the Speck Plan project in year 2010 Proposed Project could be compared. The year 2010 No Project traffic scenario 2.6-6 Transportation and Circulation ADT Volumes in 1,000s exhibiE 2.6 -1 Year 2000+ Proposed Project ADT Volumes HIDDEN CREEK RANCH SPECIFIC PLAN: SPRING ROAD EXTENSION Hidden Creek Ranch Specific Plan Spring Road Connection assumes buildout of the City of Moorpark General Plan Land Use Element and surrounding cumulative growth, without the proposed project. This scenario was developed by using the MTAM. The findings of the year 2010 analysis are as follows. The following circulation system improvements will be required in addition to the Year 2000 No Project scenario minimum circulation system in order to accommodate the Year 2010 No Project scenario traffic demands. Intersection levels of service are identified in Table 2.6-4. • Year 2000 minimum circulation system with the improvements at Los Angeles Avenue /Spring Road, Los Angeles Avenue/Tierra Rejada Road and one of the options for the Collins Drive /Campus Park Drive intersections. • The Spring Road extension, C Street, the Casey Road extension, and the completion of Science Drive. • Six -lane roadway section along New Los Angeles Avenue /Los Angeles Avenue with intersection configurations (Exhibit 3.6 -15 of the Hidden Creek Ranch Specific Plan EIR). • Extension of SR -118 west from the SR- 118/SR -23 connection to Los Angeles Avenue as a four -lane expressway with at -grade intersections at Spring Road, Walnut Canyon Road, C Street, and Gabbert Road. (This roadway can be initially constructed as a two- lane facility, with the additional lanes being added when needed.) • Traffic signal installation at the SR- 11811Nalnut Canyon Road and SR- 118 /Spring Road intersections. The majority of the traffic study area intersections will maintain LOS C or better, with the exception of two of the 22 study intersections, which are projected to exceed the City of Moorpark LOS C or better objective during the a.m. peak hour time period. The Collins Drive /Campus Park Drive intersection is forecast to operate at LOS E in the a.m. peak hour; the Collins Drive /SR -118 westbound ramps are forecast to operate at LOS D in the a.m. peak hour. Improvements The following intersection improvements will be required at two locations to attain the City of Moorpark LOS C or better objective under the year 2010 No Project scenario traffic conditions. These improvements to the year 2000 No Project scenario minimum circulation system are considered as the minimum circulation system for the year 2010 No Project scenario. • Collins Drive /Campus Park Drive. In order to achieve the City of Moorpark performance objective of LOS C or better, the signal phasing and intersection reconfiguration would be needed. A new "free" northbound right -tum lane and a second westbound left-tum lane will be provided. 2.6-7 Transportation and Circulation Hidden Creek Ranch Speck Plan Spring Road Connection TABLE 2.6-4 YEAR 2010 NO SPECIFIC PLAN OR SPRING ROAD CONNECTION PROJECT PEAK HOUR LEVELS OF SERVICE Collins Drive /SR -118 Westbound Ramps. Improvements required to achieve the City of Moorpark objective of LOS C or better include the widening of the offramp to provide two right -tum lanes. The westbound approach at this intersection will be striped for a left -tum lane and two right -tum lanes. In order for the operations of this intersection to accommodate the high westbound right -turn demand, the east curbline on Collins Drive north of the offramp will need to be relocated to the east to align with the northbound right -turn curbline at the Campus Park Drive intersection.

Year 2010 Proposed Proiect Analysis Potential impacts of the proposed project on the Year 2010 No Project scenario minimum circulation system were reassessed assuming full buildout of Specific Plan with the Spring Road connection (and no Broadway Road extension) across Happy Camp Canyon Regional Park. The following discussion presents the results of this analysis. Land Use and Traffic Volumes The traffic volumes expected to be generated by full buildout of the Speck Plan were added to the year 2010 No Project scenario traffic volumes. The year 2010 Proposed Project scenario (full project buildout) will generate 47,206 daily, 2,933 a.m. and 3,790 p.m. peak hour trips. The projected volumes were distributed and assigned to the year 2010 minimum circulation system with the Spring Road connection. Exhibit 2.6 -2 depicts year 2010 Proposed Project ADT traffic volumes, respectively. The level of service worksheets are contained in Appendix D of this study. Under the Year 2010 scenario, the connection between Walnut Canyon Road and Spring Road is assumed. This connection, the extension of Spring Road, and the deletion of Broadway Road through Happy Camp Canyon Regional Park result in no new significant traffic impacts. The year 2010 with project scenario includes the SR -118 bypass as part of the regional circulation system. With this circulation system in place, changes in turning movements and related traffic volumes for the following affected intersections would be less than significant: Moorpark Avenue /High Street, High Street/Spring Road, future SR- 118/Walnut Canyon Road, and SR- 118 /Spring Road. 2.6-9 Transportation and Circulation Hidden Creek Ranch Speck Plan Spring Road Connection MITIGATION MEASURES No additional mitigation would be required beyond that addressed in the Hidden Creek Specific Plan draft EIR. CONCLUSIONS Changes to the project circulation system associated with the implementation of the Spring Road connection and deletion of the Broadway Road connection as part of the proposed Hidden Creek Ranch Specific Plan project would not result in any new significant or unavoidable traffic impacts. Implementation of a Spring Road connection instead of a Broadway Road connection would direct vehicular traffic intotthrough the downtown Moorpark area, whereas the Broadway connection would direct traffic north of the city, the latter which is not expected to be as desirable to motorists. 2.6-10 Transportation and Circulation F" ADT Volumes in 1,000s exhibit 2.6-2 Year 2010+ Proposed Project ADT Volumes HIDDEN CREEK RANCH SPECIFIC PLAN: SPRING ROAD EXTENSION Hidden Creek Ranch Specific Plan Spring Road Connection 2.7 AIR QUALITY An air quality analysis was prepared for the Hidden Creek Ranch Specific Plan project. The following discussion pertains to the proposed Spring Road extension and, therefore, does not repeat the extensive background information provided in the Hidden Creek Ranch Specific Plan EIR. EXISTING CONDITIONS Regional The proposed Hidden Creek Speck Ranch Plan site is located in the City of Moorpark's Area of Interest, an unincorporated portion of Ventura County. Ventura County is divided into three airsheds. The northern half of the county is designated as the North Half airshed. The southern half of Ventura County is divided into two airsheds, the Ojai Valley Airshed and the Oxnard Plain Airshed. Each of the three airsheds are characterized by different meteorological influences and air pollution dispersion patterns. The Specific Plan site is located within the Oxnard Plain Airshed. Ambient air quality is monitored by the Ventura County Air Pollution Control District (VCAPCD) at facilities located in Ojai, Ventura, Simi Valley, Thousand Oaks, Piru, Anacapa Island, and El Rio. Contaminant levels in air samples are compared to federal and state standards to determine air quality. These standards are set by the U.S. Environmental Protection Agency (EPA) and the Air Resources Board (ARB) at levels to protect public health and welfare with an adequate margin of safety. There are federal and state standards for ozone, carbon monoxide, nitrogen dioxide, PM,o (suspended particulate matter 10 microns or less in diameter), sulfur dioxide, and lead. California has also set standards for sulfate, vinyl chloride, hydrogen sulfide, and visibility- reducing particles. The National Ambient Air Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS) are shown in Table 2.7 -1. Attainment Status The ARB is required to designate areas of the state as attainment, nonattainment, or unclassified for air quality standards. An attainment designation for an area signifies that pollutant concentrations did not violate the standard for that pollutant in that area. A nonattainment designation indicates that a pollutant concentration violated the standard at least once, excluding those occasions when a violation(s) was caused by an exceptional event, as defined in the criteria. 2.7 -1 Air Quality Hidden Creek Ranch Specific Plan Spring Road Connection TABLE 2.7 -1 AMBIENT AIR QUALITY STANDARDS The air pollutants of most concern in Ventura County are ozone and fine particulate matter (PM10). Carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead levels in all areas of Ventura County are below federal and state standards. These criteria pollutants and the levels at which they occur in the Oxnard Plain Airshed is provided below. • Ozone. Ventura County has not attained federal (except in the northern half of the county) (PM10) and state standards for ozone. Total Suspended Particulates/Particulate Matter. Ventura County is classified as in non - attainment for the state PM10 standard. However, Ventura County is in attainment of the federal PM10 standard. • Carron Monoxide. Local CO "hotspots" may currently occur at severely congested intersections, but in general, carbon monoxide is generally not a problem in Ventura County. The entire county is in attainment of the national and state standards for carbon monoxide. 2.7 -2 Air Quality National Standard Primary Secondary Air Pollutant California Standard Ozone >0.09 ppm, 1 -hr. avg. >0.12 ppm, 1 -hr. avg. >0.12 ppm, 1 -hr. avg.

The air pollutants of most concern in Ventura County are ozone and fine particulate matter (PM10). Carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead levels in all areas of Ventura County are below federal and state standards. These criteria pollutants and the levels at which they occur in the Oxnard Plain Airshed is provided below. • Ozone. Ventura County has not attained federal (except in the northern half of the county) (PM10) and state standards for ozone. Total Suspended Particulates/Particulate Matter. Ventura County is classified as in non - attainment for the state PM10 standard. However, Ventura County is in attainment of the federal PM10 standard. • Carron Monoxide. Local CO "hotspots" may currently occur at severely congested intersections, but in general, carbon monoxide is generally not a problem in Ventura County. The entire county is in attainment of the national and state standards for carbon monoxide. 2.7 -2 Air Quality Hidden Creek Ranch Speck Plan Spring Road Connection • Nitrogen Dioxide. Nitrogen dioxide levels in Ventura County are well below the ambient air quality standards. The entire county is in attainment of the state and national nitrogen dioxide standards. • Sulfur Dioxide and Lead. Sulfur dioxide and lead levels in all areas of the county are below national and state standards. The entire county is in attainment for these pollutants. Local Air Quality Setting The roadway study area is located in Ventura County. The air quality data from the Simi Valley air quality monitoring station best represents the ambient air quality in the project vicinity. Ambient levels of ozone have exceeded state and federal 1 -hour standards in each of the last five years. Similarly, ambient levels of PM,o have exceeded state standards in each of the past five years at the Simi Valley monitoring station. However, within the past five years, there have been no exceedances of the state or federal standards for carbon monoxide and nitrogen dioxide, or the federal standard for PM,o. Regulatory Setting The federal Clean Air Act (CAA) requires designated agencies in any area of the nation that does not meet the NAAQS to prepare a plan demonstrating the steps that will be taken to bring the area into compliance. The national deadline for meeting all standards was December 31, 1987. The 1990 amendments to the federal CAA extend ozone attainment deadlines to the year 2010 for areas with extremely degraded air quality. The designated planning agency in Ventura County is the VCAPCD. In November 1994, the VCAPCD adopted the 1994 Air Quality Management Plan (plan). The primary purpose of the Ventura County 1994 AQMP is to satisfy the planning requirements of the 1990 federal CAA Amendments and to outline a strategy for meeting the federal ozone clean air standards by 2005, while accommodating a reasonable and inevitable amount of growth. The 1994 AQMP relies on the efforts of many agencies to implement various clean air programs in Ventura County. These agencies include each of the ten cities in Ventura County, the County of Ventura, the Ventura County Transportation Commission, local transit agencies (South Coast Area Transit, the cities of Simi Valley and Thousand Oaks, and the County of Ventura), Caltrans, the California Air Resources Board, the California Bureau of Automotive Repair, the U.S. Environmental Protection Agency, and the VCAPCD. A draft 1995 AQMP revision was issued by the VCAPCD in July 1995. This 1995 revision was prepared to update information that has changed in the past year since the 1994 AQMP was 2.7 -3 Air Quality Hidden Creek Ranch Specific Plan Spring Road Connection approved by the Air Pollution Control Board on November 8, 1994. However, the updates do not affect air quality analysis for this project. The federal CAA also requires that projects receiving federal funds demonstrate conformity to the approved local Air Quality Management Plan (AQMP). The 1989 Guidelines are included in the 1991 AQMP as Appendix G -91. The conformity guidelines extend this requirement to all proposed projects capable of emitting more than 25 pounds per day of either ROC or NOx, regardless of whether federal funding is being sought. The primary method of demonstrating AQMP consistency is by showing that a project is consistent with the population or employment forecasts in the plan. IMPACTS Significance Criteria In accordance with CEQA, a project will be considered to have a significant impact on air quality if the project "violates" any ambient air quality standard, contributes measurably to an existing air quality violation, or exposes sensitive receptors to substantial levels of pollutants. On October 24, 1989, the Ventura County Air Pollution Control Board (APCB) adopted the District's Guidelines For The Preparation of Air Quality Impact Analyses (herein referred to as 'The 1989 VCAPCD Guidelines "), which is still the current methodology used in Ventura County for assessing air quality impacts. The 1989 Guidelines are included as Appendix G -91 in the 1991 Air Quality Management Plan adopted October 8, 1991. The 1991 AQMP contains the following statement regarding the applicability of the 1989 Guidelines: The purpose of the Guidelines which became effective January 1, 1990, is to provide District staff, lead agencies, consultants, and project applicants with uniform procedures for preparing the air quality sections of environmental documents pursuant to CEQA. The guidelines establish criteria to determine the air quality significance of discretionary land use projects .... All of the cities in Ventura County, except Simi Valley, acting as lead agencies for projects are using the Guidelines for CEQA review purposes. Although the 1989 VCAPCD Guidelines state that the determination of significance must be made by the lead agency, the guidelines recommend the following additional definition of significance. In addition to the CEQA definitions of significance, the Ventura County Air Pollution Control Board has adopted a policy which states that future general development projects located in the Ojai Valley Clean Air Ordinance (CAO) area and the Ventura 1 Nongrowth area which emit 5 pounds or more per day of either reactive organic compounds (ROC) or oxides of 2.7 -4 Air Quality Hidden Creek Ranch Specific Plan Spring Road Connection nitrogen (Nox), or general development projects located in the remainder of the ozone nonattainment area of the county which emit 25 pounds or more per day of either ROC or NO, will individually and cumulatively have a significant adverse impact on air quality. Therefore, because the roadway study area is located in the Oxnard Plain Airshed and pursuant to the VCAPCD Guidelines that are used by the City of Moorpark, the significance of the project - related ROC and NOX emissions will be assessed under the 25 pound - per -day (lb /day) significance threshold contained in the 1989 VCAPCD Guidelines. The potential air quality impacts of the proposed Spring Road extension have been analyzed using the emission factors developed by the ARB. Emissions from the project fall into two major categories: • Construction Emissions: Airborne dust and emissions from heavy equipment used during the construction. • Operational Emissions: Vehicle emissions resulting from traffic using Spring Road; onsite operational emissions and offsite emissions generated as a result of energy consumption. Construction Impacts The roadway construction will produce two types of air contaminants: exhaust emissions from construction equipment, materials transport, and employee travel, and fugitive dust generated as a result of soil disturbance, grading, and earthwork. Although emissions produced during grading and construction activities can result in significant impacts, these effects are short- term /moderate -term. Exhaust Emissions From Construction Equipment Construction activities produce exhaust emissions associated with the transport of workers and machinery to and from the site, as well as from equipment onsite. Though the specific mix and number of pieces of equipment used have not been determined, exhaust emission factors as determined by the EPA and incorporated into the Ventura County Guidelines, for various types of equipment used during construction operations are presented in Table 2.7 -2. Exhaust emissions can vary substantially from day to day, depending on the level of activity. As stated in the 1989 VCAPCD Guidelines, construction- related emissions of ROC and NOX are not counted toward the 25- pound - per -day significance threshold since these emissions are considered to be temporary. 2.7 -5 Air Quality Hidden Creek Ranch Specific Plan Spring Road Connection TABLE 2.7 -2 EXHAUST EMISSIONS FROM CONSTRUCTION EQUIPMENT (lbs /day)' Equipment Emissions (lb /day) ROCb NO,` Tracked tractor 0.96 10.08 Wheeled tractor 1.52 10.16 Wheeled dozer 1.52 33.28 Motor grader 0.32 0.40 Scraper 2.24 30.64 Wheeled loader 2.00 15.12 Tracked loader 0.80 6.64 Off-highway truck 1.52 33.28 Roller 0.56 6.96 Miscellaneous 1.20 13.52 ' Based on an 8 -hour workday ROC: Reactive organic compounds.

Fugitive Dust Emissions Heavy construction creates dust emissions that may have substantial temporary impacts on local air quality. Building and road construction are the construction categories with the highest emissions potential. Dust emissions also vary substantially from day to day, depending on the level of activity, specific operations, and weather conditions. A large portion of the emissions result from equipment traveling over unpaved roads at the construction site. Depending upon prevailing wind conditions, these emissions can be troublesome to workers and nearby sensitive receptors. The 1989 VCAPCD Guidelines state that it is not necessary to estimate the amount of fugitive dust that will be generated by project construction. However, the EPA estimates that each acre of soil disturbed creates about 110 pounds of dust per workday, or 1.2 tons per acre per month, 2.7 -6 Air Quality Hidden Creek Ranch Specific Plan Spring Road Connection during the construction life of a typical project. This value depends on soil moisture, silt content, wind speed, activity level, and many other factors. Fugitive dust will be produced primarily during grading and other site preparation activities, but will also be produced during building construction. Through watering and other dust control measures required by the VCAPCD, dust emission rates can be reduced by approximately 50 to 75 percent. Without mitigation, fugitive dust generated during the construction phase of the roadway will result in temporary, but significant impacts offsite. The Ventura County Environmental Health Department and the VCAPCD have identified San Joaquin Valley Fever (coccidioidomycosis) as a potentially significant adverse health impact resulting from large -scale grading and excavation operations in the inland areas of Ventura County. These activities for the proposed project may expose construction workers and others to San Joaquin Valley Fever. This is a potential significant adverse health impact. Long -Term Impacts Regional Impacts Long -term regional impacts are those associated with vehicular travel on Spring Road. It should again be noted that the Spring Road connection is being considered as a replacement for Broadway Road through Happy Camp Canyon Regional Park associated with the Hidden Creek Ranch Specific Plan project. Therefore, the use of Spring Road, instead of Broadway, will not result in any new significant regional air quality impacts. Local Impacts No localized air quality impacts (i.e., CO "hotspots ") are expected. No significant impacts would occur. CONSISTENCY WITH THE 1991 AIR QUALITY MANAGEMENT PLAN As stated in the Hidden Creek Ranch Specific Plan EIR, the proposed Specific Plan will allow population growth for the subregion, and, therefore, is consistent with the AQMP with the Spring Road or Broadway Road connection. Since the proposed Spring Road connection would not result in a change in the projected population, the proposed roadway would also be consistent with the AQMP. 2.7 -7 Air Quality Hidden Creek Ranch Specific Plan Spring Road Connection CUMULATIVE IMPACTS As noted in the Hidden Creek Ranch Specific Plan EIR, the 1989 VCAPCD Guidelines states that, a project which exceeds 25- pounds - per -day of either ROC or NO,, will individually and cumulatively have a significant impact on air quality. The project, in conjunction with other planned, proposed, and approved projects in the region will cumulatively contribute to existing exceedances of air quality standards. Therefore, the Specific Plan will have a significant cumulative impact on air quality since its ROC and NO,, emissions are projected to exceed VCAPCD significance thresholds. There would be no change in the proposed land uses associated with the use of Spring Road instead of Broadway Road. MITIGATION MEASURES No additional mitigation would be required. Those measures identified in the draft EIR which apply to the Spring Road connection are as follows: Short -term Construction Measures 1. All site access roads shall be covered with gravel during all construction periods as required by the city engineer. 2. Stabilizes (e.g., chemical, hydroseeding, etc.) shall be applied to completed cut and fill areas andlor all graded areas as required by the city engineer. 3. All grading equipment engines shall be maintained in good condition and in proper tune as per manufacturers' specifications. Equipment not in use for more than 10 minutes shall be turned off. 4. During the smog season (May to October), the construction manager shall order that construction cease during Stage I alerts to minimize the number of vehicles and equipment operating, lower ozone levels, and protect equipment operators from excessive smog levels upon notification by the city. 5. All project developers shall ensure that contractors properly maintain and operate construction equipment and use direct injection diesel engines or gasoline powered engines if feasible: 6. Dust generation produced during grading shall be suppressed by the following activities: a. All active portions of the construction site shall be watered sufficiently to prevent excessive amounts of dust. Complete coverage watering shall occur at least twice daily, preferably in the late morning and after work is done for the day. b. All material excavation or grading shall be sufficiently watered to prevent excessive amounts of dust. 2.7 -8 Air Quality C1 0.5 0 exhibit 2.8-1 2 SCALE IN MILES Noise Monitoring Locations HIDDEN CREEK RANCH SPECIFIC PLAN: SPRING ROAD EXTENSION Hidden Creek Ranch Speck Plan Spring Road Connection 2.8 NOISE EXISTING CONDITIONS The Noise Element of the General Plan of the City of Moorpark contains goals, noise evaluations, and measurements, findings, problem summary, and policy programs that pertain primarily to the protection of residential uses. The following summarizes pertinent information for the proposed Spring Road connection through Happy Camp Canyon Regional Park. General Noise Characteristics Sound level is the frequency- weighted sound pressure level obtained with the standardized dynamic characteristic "fast" or "slow" and weighting A or C. Community noise levels are normally measured in terms of the "A- weighted decibel," abbreviated dBA. A- weighting is a frequency correction that correlates overall sound pressure levels with the frequency response of the human ear. Additional units of measurement have been developed to evaluate the longer term characteristics of sound. The equivalent noise level (Leq) is a single- number representation of the fluctuating sound level in decibels over a specified period of time. It is a sound - energy average of the fluctuating level. A maximum permissible hourly noise level (1-50) is defined as the weighted noise level equaled or exceeded during 50 percent of a stated time period. For steady sources, the L50 and Leq levels are virtually the same. The Community Noise Equivalent Level (CNEL) is the noise and land use compatibility criteria most widely used in the State of California. The CNEL measurement represents an average of all measured noise levels obtained over a specified period of time. The CNEL scale represents a time - weighted 24 -hour average noise level based on the A- weighted decibel. Time - weighted refers to the fact that noise that occurs during certain sensitive time periods is weighted (in calculations) more heavily. The CNEL scale includes an additional 5 dBA adjustment to sounds occurring in the evening (7 p.m. to 10 p.m.) and a 10 dBA adjustment to sounds occurring in the late evening and early morning hours (between 10 p.m. and 7 a.m.). It is important to note that an A- weighted noise level is a measure of the noise level at any point in time, while the CNEL is a measure of the noise exposure over a full day. Regulatory Noise Setting State and local governments have established noise standards and guidelines to protect citizens from potential hearing damage and various other adverse physiological and social effects associated with noise. 2.8-1 Noise Hidden Creek Ranch Speck Plan Spring Road Connection There are no federal or state standards limiting construction noise. Many cities and counties have provisions in their noise ordinances that address construction noise levels and time of operation. For a relatively long -term noise exposure resulting from construction activities, a CNEL up to 65 dBA is generally acceptable for noise sensitive land uses, including residences, schools, hospitals, and churches. A CNEL up to 75 dBA is often considered acceptable for office buildings and other commercial activities. However, for short-term construction activities, levels considerably higher may be acceptable because of the temporary nature of the activity. The applicable standards and guidelines for the Spring Road connection are discussed below. State of California The State of California has adopted noise standards in areas of regulation not preempted by the federal government. State standards regulate noise levels of motor vehicles and freeway noise affecting classrooms, set standards for sound transmission control and occupational noise control, and identify noise insulation standards. The state has also developed the following land use compatibility guidelines for community noise environments. The California Sound Transmission Control Standards are found in the California Code of Regulation, Title 24, Building Standards, Chapter 2.35 as adopted March 1, 1986. The purpose of the standards is to establish minimum noise insulation performance standards to protect persons within new hotels, motels, apartment houses, and dwellings other than detached single - family dwellings. The standards state that interior noise levels with windows closed attributable to exterior sources shall not exceed an annual noise level of 45 dBA CNEL in any habitable room. In addition, residential buildings or structures within a 60 dBA CNEL from airport, vehicular, or industrial noise sources shall require an acoustical analysis showing that the proposed building has been designed to limit intruding noise to the allowable 45 dBA CNEL interior noise level. In "Guidelines for the Preparation and Content of Noise Elements of the General Plan," (February 1976), the state Office of Noise Control provided guidance for the acceptability of projects within specific CNEL contours. Residential uses, churches, libraries, and schools are normally unacceptable in areas exceeding 70 dBA CNEL and conditionally acceptable between 60 and 70 dBA CNEL. Professional and commercial office buildings are normally unacceptable in areas exceeding 75 dBA CNEL and conditionally acceptable between 67 and 77 dBA CNEL. However, the state stresses that these guidelines can be modified to reflect sensitivities of individual communities to noise. City of Moorpark The City of Moorpark has adopted noise standards for land uses in its Noise Element of the General Plan (April 1986). The exterior noise standard in outdoor living areas is 65 dBA CNEL. 2.8-2 Noise Hidden Creek Ranch Specific Plan Spring Road Connection The interior noise standard is 45 dBA CNEL. The city does not have additional or specific noise standards for other noise - sensitive uses such as hospitals, parks, and schools. In general, the same noise standards should be used for these noise sensitive uses, as well as state standards for maximum interior sound levels for schools. Currently, the city has not adopted any specific noise limits in its noise ordinance. Construction activities are regulated on a case -by -case situation (i.e., through conditions placed on planned development permits and zoning clearances for building permits); construction hours are specified if potential noise impacts will occur in noise sensitive areas. Construction hours near noise sensitive land uses are limited by city Municipal Code to 7 a.m. to 7 p.m. Monday through Saturday. Community Ambient Noise Degradation In addition to the criteria discussed above, another consideration in defining impact criteria is based on the degradation of an existing noise environment. About ten percent of the population is so sensitive to noise that they object to any noise not of their own making. Thus, some complaints occur even in the quietest environments. Another sizable portion of the population (about 25 percent), however, does not react or complain even in very severe noise exposure. Therefore, one should expect a variety of reactions from the people exposed, ranging from serious annoyance to no awareness. People can be expected to respond to changes in level as follows: • Except in carefully controlled laboratory experiments, an increase or decrease of only 1 dBA cannot be perceived. • Outside the laboratory, a 3 dBA increase or decrease is considered a just - noticeable difference. • An increase or decrease of at least 5 dBA is required before any noticeable change in community response would be expected. • A 10 dBA increase is subjectively heard as a doubling in loudness and would almost certainly cause adverse change in community response. A 10 dBA decrease is subjectively heard as a halving in loudness and represents a significant improvement in a noise environment. In the "Caltrans Noise Abatement Programs" from the Highway Design Manual, Chapter 1100, "Highway Traffic Noise Abatement" published by Caltrans, a "substantial increase" in noise level is defined to be 3 dBA from the reference (existing) level for community (Type 11) and school noise abatement programs. 2.8-3 Noise Hidden Creek Ranch Specific Plan Spring Road Connection Therefore, if the increase in noise exposure level is greater than 3 dBA, the significance of impact will depend on the ambient noise level and the presence of noise sensitive sites. Noise impacts can be considered "possibly significant" if increases in noise exposure levels are expected to be no greater than 5 dBA with implementation of the project. Noise impacts can be considered "generally significant" if the proposed project will cause noise standards or ordinances to be exceeded, or increases in the community noise levels by 6 to 10 dBA in built- up areas, or increases by 10 dBA or more in rural areas. Existing /Baseline Noise Levels Existing environmental noise levels in the greater area are dominated by residential and vehicular noise, with contributions from winds and other natural sources. Ambient Noise Survey The technical appendix for the proposed revision to the Noise Element of the City of Moorpark (Mestre Greve Associates, June 1994) included 20 short-term (15 minutes) and 7 long -term (24- hour) noise monitorings throughout the city. An ambient noise survey was conducted by Michael Brandman Associates staff on September 20, 1994 to supplement the existing noise environment data for the proposed Hidden Creek Ranch Speck Plan project. No additional surveys were conducted for the Spring Road connection study. Short-term (30 minute) noise samples were gathered during a.m. and p.m. peak traffic hour periods at four locations of interest in the project vicinity. The noise measurement locations are depicted in Exhibit 2.8 -1 and are representative samples of the study area. The results of the short-term noise measurements are shown in Table 2.8 -1. The table identifies the equivalent (average) A- weighted sound levels generated during each sample as well as the maximum and minimum sound levels. The Leq is the level of a steady sound which has the same A- weighted sound energy as the time - varying sound. The maximum and minimum sound levels are the A- weighted maximum and minimum, respectively, sound levels measured during the entire measurement period. It is seen from the measurement results that ambient noise level in the Specific Plan area generally reflects an environment of rural/suburban characteristics. Community activities, such as automobiles, bus/trucks, school, children, birds and dogs, and landscaping equipment, are the dominant sources contributing to the ambient noise. Leq varies from 47.9 to 65.5 dBA over short-term periods, depending on the time and location it was measured. Long -term (24- hours) noise monitoring showed 55 dBA CNEL, which is typical of a rural/suburban area. 2.8-4 Noise Hidden Creek Ranch Specific Plan Spring Road Connection TABLE 2.8 -1 EXISTING MEASURED AMBIENT NOISE LEVELS, dBA 2.8-5 Noise Sound Levels (dBA) L egg Lmax° Lmin` Site No. Location Noise Source 1 Campus Park Drive /Beragan Street 8:00 a.m. - 8:30 a.m. 61.4 71.9 45.8 d,e 5:15 p.m. - 5:45 p.m. 57.4 63.2 46.6 d,e,f 2 North end of Pecan Avenue 12:00 p.m. - 12:30 p.m. 40.4 51.3 31.8 g,h,i 4:25 p.m. - 4:55 p.m. 49.4 64.3 37.5 d,e, ,' 3 Campus Road /University Drive 8:35 a.m. - 9:05 a.m. 65.5 72.5 43.8 d,e,g,k 2:05 p.m. - 2:35 p.m. 62.1 72.5 45.5 d, 4 Happy Camp Canyon 4oa 3 52.6 2:5 . m:15 p m .9 66.8 33.0 e g, h 3:45 p.m. - 4:15 p.m. 5 Campus Canyon School' 11:00 a.m. - 11:15 a.m. 52.1 67.9 41.6'" n /a" 6 Campus Park' 3:45 p.m. - 4:00 p.m. 60.6 69 55.1 n/a 7 Paul Griffin Park' 11:25 a.m. - 11:40 a.m. 52.6 58.7 47.4 n/a 8 6406 Gransen Court' 11:50 a.m. -12:05 p. m. 55.4 61.3 50.3 n/a 9 6485 Westwood' 24 hours 55.0` n/a a Leq is the equivalent constant noise level over the entire monitoring period.

Vehicular traffic is the only dominant noise source that can be predicted with model calculations. Existing traffic noise levels were calculated using the Federal Highway Administration's (FHWA) Highway Noise Prediction Model, FHWA -RD -77 -108 (December 1978). Model input data included average daily traffic levels; typical Southern California traffic mix of day /night percentages of autos, medium, and heavy trucks for local streets; annual average truck percentage on SR -118 based on the 1989 Annual Average Daily Truck Traffic on the California State Highway System (Caltrans, September 1990); vehicle speeds; ground attenuation factors; and roadway widths. Average Daily Traffic (ADT) volumes were provided by Associated Transportation Engineers for both existing conditions and year 2010 conditions for the proposed Specific Plan project. Table 2.8-2 shows that, in general, traffic noise levels in the Hidden Creek Ranch Specific Plan area are low to moderate, with the 70 dBA CNEL confined within the roadway right -of -way for all local streets. Half of the existing roadway segments analyzed had the 65 dBA CNEL also confined within the roadway right -of -way. SR -118 is a major noise source in the area, with the 70 dBA CNEL extending to 339 feet from the centerline of the freeway. Year 2010 Baseline Traffic Noise Levels In order to establish baseline information in and around the area, traffic noise levels along roadway segments affected in the area for the future year 2010 without the Specific Plan project are calculated. The traffic noise levels were calculated for most affected roadway segments identified in and around the area using the same Highway Noise Prediction Model as the one used for the existing conditions. Table 2.8 -3 indicates that traffic noise levels increase (from 0.5 to 3.9 dBA) over their corresponding existing levels on most of the roadway segments in the vicinity of the Specific Plan area under the future year 2010 without the Specific Plan, except along Princeton Avenue south of SR -118, where traffic noise level would decrease 3.7 dBA from its existing level due to redistribution of traffic in this area.

Short-term impacts would be due to noise generated by vehicles and equipment during the 2.8-8 Noise Hidden Creek Ranch Specific Plan Spring Road Connection construction phases. Long -term impacts would be associated with future project- related noise impacts to the study area and noise impacts to the proposed project. Significance Criteria • Generation of long -term noise levels that exceed the city's exterior noise criteria (i.e., noise levels in excess of CNEL of 65 dBA for residential uses or 70 dBA for commercial uses). • The noise impact is considered "generally not significant" if no noise sensitive sites are located in the project area, or if increases in community noise level with the implementation of the project are expected to be 3 dBA or less at noise sensitive locations, and the proposed project will not result in violations of local ordinances or standards. If the increase in noise exposure level is greater than 3 dBA, the significance of impact will depend on the ambient noise level and the presence of noise - sensitive sites. Noise impacts can be considered "possibly significant" if increases in noise exposure levels are expected to be no greater than 5 dBA with implementation of the project. Noise impacts can be considered "generally significant" if the proposed project will cause noise standards or ordinances to be exceeded, or increases in the community noise levels by 6 to 10 dBA in built -up areas, or increases by 10 dBA or more in rural areas. Short-term Construction Noise Impacts Construction noise represents a short-term impact on ambient noise levels on and around the area over the period of roadway construction. Noise generated by construction equipment, especially diesel - powered equipment, including earth movers, material handlers, and portable generators, can reach high levels. The EPA has found that the noisiest equipment types operating at construction sites typically range from 88 dBA to 91 dBA at 50 feet. Noise levels for construction equipment before and after mitigation are listed in Table 2.8-4. Typical operating cycles may involve 2 minutes of full power, followed by 3 or 4 minutes at lower settings. Although noise ranges tend to be similar for all construction phases, the building phase tends to be less noisy. Noise levels vary from 79 dBA to 88 dBA at 50 feet during this phase of construction. Construction of the proposed Spring Road connection would generate noise during grading, heavy vehicle movement, and paving work. Specifically, noise would be generated by diesel - powered heavy duty equipment such as haul trucks, cement and asphalt trucks, graders, and bulldozers. The noisiest earthmoving construction equipment produces noise levels between 89 to 91 dBA at a distance of 50 feet (see Table 2.8 -4). The proposed roadway construction is approximately 800 feet from the closest residences. Consequently, using basic noise attenuation methodology of 6 decibels per doubling of distance for point sources, these 2.8-9 Noise Hidden Creek Ranch Speck Plan Spring Road Connection residences would be exposed to noise levels of less than 65 dBA (the city's criteria for residential uses). As stated previously in the Hidden Creek Ranch Specific Plan draft EIR, although the construction noise impact is considered to be sometimes adverse, due to the temporary nature of the construction activities, it would be at a level that is considered to be less than significant.

Long -term Noise Impacts From Vehicular Traffic Year 2010 With Project Traffic Noise Levels Operation of the proposed project, in conjunction with traffic generated by other developments in the surrounding area, would result in increases in motor vehicle volumes on the Spring Road connection and decreases in traffic volumes along Walnut Canyon Road and SR -118 between 2.8-10 Noise Hidden Creek Ranch Specific Plan Spring Road Connection Walnut Canyon Road and Spring Road. This decrease in daily traffic volumes along Walnut Canyon Road would cause a traffic noise level decrease of 2 dBA. The decrease in daily traffic volumes along SR -118 would cause a traffic noise level decrease of approximately 0.3 dBA. However, this increase in daily traffic volumes would cause noise levels generated by the Spring Road connection to increase by 1.1 dBA. However, because the alignment of Spring Road through Happy Camp Canyon Regional Park has been shifted approximately 600 feet further to the north than the alignment presented to the Moorpark Planning Commission, the 1.1 dBA decibel increase will not be discernable. Residents would be exposed to noise levels of less than 61 CNEL. Since the proposed project would not cause noise level increases above the City of Moorpark residential threshold of 65 CNEL, this impact is considered to be less than significant. CUMULATIVE IMPACTS Construction trucks from multiple construction sites within a quarter mile of each other would potentially cause significant short-term construction impacts in the project vicinity. No significant cumulative construction noise impacts except more frequent high single event truck noise are anticipated. Baseline traffic noise levels calculated for the Hidden Creek Ranch Speck Plan project for the year 2010 included traffic trips for other planned, proposed, and approved projects in the region, except the proposed Speck Plan project. Year 2010 baseline traffic noise levels would have more than 3 dBA increases over their corresponding existing levels along Campus Park Drive and Spring Road. Year 2010 baseline plus the Specific Plan project traffic noise levels along Spring Road could have a greater than 3 dBA increase over the baseline levels. Traffic noise level increases along other roadways would all have less than 3 dBA increases over their corresponding existing levels. The proposed Specific Plan project would cause significant traffic noise level increases over the baseline levels, and would cumulatively contribute to more than 3 dBA increases along Campus Park Drive and Spring Road over their existing levels. This is considered a significant cumulative noise impact. MITIGATION MEASURES Short-term Construction Noise The following mitigation measures should be implemented during all roadway construction activities: 2.8-11 Noise Hidden Creek Ranch Speck Plan Spring Road Connection 1. Construction activities shall be limited to between the following hours: 7 a.m. and 7 p.m. Monday through Saturday. No work is to be accomplished on Sunday and federal holidays. 2. Construction equipment shall be fitted with modem sound - reduction equipment. Long -term Traffic Noise 3. Prior to the issuance of grading permits for the Spring Road connection, a licensed acoustical engineer shall review the grading and construction plans to determine if noise attenuation features, such as berms or walls, should be constructed to ensure that residential units, schools, parks, or similar noise sensitive receptors are located outside of the 65 dBA CNEL zone. CONCLUSIONS There would be no new project- related significant unavoidable adverse noise impact after implementation of the recommended mitigation measures for short -term and long -term noise events. 2.8-12 Noise Hidden Creek Ranch Specific Plan Spring Road Connection 2.9 CULTURAL RESOURCES This section summarizes information contained in the cultural resources technical report prepared for the proposed Spring Road connection by W and S Consultants. W and S Consultants prepared a Phase I archaeological survey and cultural resources assessment report in April 1996. The complete cultural resources technical report is contained in Appendix E of this study. EXISTING CONDITIONS The cultural resources assessment included an archival records check through the UCLA Institute of Archaeology, Archaeological Information Center (AIC). The UCLA AIC serves as one of the regional clearinghouses for archaeological site records for southern California. Site data were supported with field surveys conducted by W and S Consultants on April 29 and April 30, 1996. An assessment of potential historic resources in the study area for the roadway alignment was based upon a review of historic maps including the 1921 and 1941 USGS Piru quadrangles, the subdivision map of Epworth (May 1893), the subdivision map of Fremont (April 1894), and the subdivision map of Moorpark (November 1990). Field surveys were conducted to support these findings. Area History and Culture The first useful chronology of populations in the project area was developed by Wallace (1955), who described four periods applicable in the southern California region. The earliest period, Early Man, was dated from some unknown era near the end of the Pleistocene to about 5500 B.C. and consisted of peoples who were large -game hunters. With the transition from the Early Man period towards the Early Millingstone period approximately 9,000 to 10,000 years ago, coastal regions throughout southern California began to consist of small native populations subsisting on gathered foods with a special reliance on hard - shelled seeds. Recent studies (Erlandson and Colton 1991) identified that small populations of coastal hunter - gatherers were in the region 7,000 years before present (B.P.) at the beginning of the Early Millingstone period. These populations neither consisted of large - game hunters nor specialized hard -seed gathers but instead were characterized as generalized foragers that relied on a variety of different kinds of terrestrial, coastal, and marine resources. 2.9 -1 Cultural Resources Hidden Creek Ranch Specific Plan Spring Road Connection Following the Early Millingstone period, a transitional stage, referred to as the intermediate period, occurred (4,000 to 3,500 years ago). There was a growing exploitation of marine resources, the appearance of the hoppar mortar and stone bowl /mortar, and a diversification and increased use in the number of chipped stone tools. It is believed that initial occupations of the study area may have occurred during the beginning of the intermediate period from about 3,500 years B.P. What followed was the Late Prehistoric period which was known as being a time of rapid development for the area's population. Ethnographically, the Moorpark region, which is considered to include the study area, lies within the territory of the Chumash ethnolinguistic group (Kroeber 1925). These Hokan speaking people occupied the area from Topanga Canyon northwest to approximately San Luis Obispo and followed a hunting - gathering - fishing subsistence pattern which incorporated a heavy reliance on maritime resources, including pelagic, littoral fishes, and shellfish. Exploitation of these resources by the Chumash was key in their evolutionary success. Additionally, the Moorpark region was a center of political activity for the Chumash. The Moorpark region was originally part of the El Rancho Simi land grant established by the Spanish government in 1795. The study area is located within the historical boundaries of this original land grant. Land within the Moorpark region has traded hands several times between 1795 and the present, serving as an area for sheep grazing activities and, subsequently, oil speculation. However, the lower Happy Camp Canyon study area appears to have been peripheral to the historical development of the region. The large majority of it has remained in open space and has been used for livestock and farming. Accordingly, beyond its use as a peripheral grazing area for cattle, the study area figures very little, if at all, directly in the history of the area. Archaeological Resources As noted above, the archaeological resources assessment conducted for the proposed project included an archival records check through the UCLA AIC. The results of the search indicated that an archaeological survey had previously been conducted in 1993. One archaeological site was recorded. This site is located in the north - central portion of the study area, in the broad open flats of Happy Camp Canyon (CA -Ven- 1128). Although the canyon has not been surveyed in its entirety, a previous archaeological survey had been conducted for approximately 283 acres located along the central- western edge. No evidence of archaeological resources was discovered. 2.9 -2 Cultural Resources Hidden Creek Ranch Specific Plan Spring Road Connection CA -Ven -1128 was first recorded in 1993. Fused shale shatter and float was noted, but the field surveyors failed to find the artifacts recorded as present at the site at the time of original discovery. The site did not appear to have been disturbed beyond the disturbance resulting principally from historical disking that existed at the time of its original recording. The field survey identified no other cultural resources of any kind, prehistoric or historical. Given that the majority of the study area lies within an active alluvial floodplain, and the fact that it has now been surveyed twice in its entirety, the likelihood that additional sites were present but overlooked during the survey is unlikely. Historical Resources Based on a review of the aforementioned historic maps, no historic resources or historic properties have been recorded within the project area. IMPACTS Significance Criteria Under the provisions and guidelines of Appendix J, Section III, of CEQA, if a proposed "project may cause damage to an important archaeological resource, the project may have a significant effect on the environment." That is, before impacts or mitigation of impacts can be addressed, site importance must be determined. CEQA, Appendix J, recommends a testing program to determine if a site may qualify as an important resource under CEQA. The goals of a testing program are to determine if a subsurface component is present, whether the areal extent of surface and /or subsurface materials may be affected by the proposed action, and if the resources in question have the potential to answer local and regional research questions. If a resource is determined to be important, a program to mitigate anticipated impacts must be implemented through avoidance or data recovery. Sites found not to be important cultural resources need not be addressed under CEQA. Historical resources are considered to be significantly affected if a structure is or potentially is a designated historic resource. Archaeological Resources One prehistoric site, CA -Ven -1128, has been recorded in lower Happy Camp Canyon. The site is located more than 1,400 feet northwest of the roadway alignment. Because of this distance, 2.9 -3 Cultural Resources Hidden Creek Ranch Specific Plan Spring Road Connection no direct or indirect impacts to CA -Ven -1128 are expected. No other cultural resources, prehistoric or historical, are likely. No impacts are anticipated. Historical Resources The records searches revealed the presence of no known historical resources within the project site. Therefore, no significant impacts on historical resources associated with the implementation of the proposed project are anticipated. CUMULATIVE IMPACTS The cumulative study area for archaeological and historical resources is defined as areas inclusive of the City of Moorpark and Ventura County. Impacts on onsite cultural resources are site - specific. Although cumulative development in conjunction with past, present, and reasonably foreseeable future development would result in the disturbance of cultural resource sites throughout the region, the City of Moorpark and Ventura County require mitigation of impacts to these resources. This includes the collection of artifacts which may contribute to local and regional history and prehistory. As a result, anticipated development in the project region would not have a significant cumulative impact on archaeological and historical resources or result in a significant cumulative loss in regional history or prehistory. CONCLUSIONS No mitigation is required. 2.9-4 Culturai Resources APPENDIX A June ,1996 Project No. 3881198 -06 To: Michael Brandman Associates 17310 Red Hill Avenue, Suite 250 Irvine, California 92714 Attention: Ms. Dana Privitt -Arita Subject: Draft Geotechnical Portion of the Environmenta Im t port Alternative Alignments for the Proposed Hidden Creek , my of tura, alifornia Reference: Leighton and Associates, Inc., 1995, tech 'cal and Phase I En nme al Site Assessment Portions of the En ' ment pact eport, Hidden ee anch Project, County of Ventura, Ca ' rnia, oject 198 -05, dated 8, 1995 In accordance with your authorize ' n, Lei on and 'ates, c., has completed the geotechnical portion of the environmental imp ct r ort fo ree alte to aL ents of the proposed Hidden Creek Drive that would extend w twar m the oposed idde Creek Ranch project, located near the City of Moorpark in Ventu Co ty, _ ' orm e r is are of our study are contained within- the attached The propos roada within he ar studied are considered feasible.

Leighton and Associates, Inc., (Leighton) has performed geological and geotechnical analyses for the Environmental Impact Report (EIR) of three alternative alignments of the proposed Hidden Creek Drive that would connect to Spring Road, located near Moorpark in Ventura County, California. This report is an addendum to the referenced EIR for the proposed Hidden Creek Ranch project. The objective of this study was to identify and * to impacts related to the proposed alternate alignments and provide recommendat' s for itigation measures related to the specific impacts of roadway development.

Basic geological information obtained from 1:24,000 scale geologic maps that include the study area (Dibblee, 1992x, b) were then tr red to the base map. Stereographic aerial photographs were analyzed and areas pot ial slope instability were noted such that subsequent field checking of these are could a performed. Review was also made of a portion of the Hidden Creek Ran Envir mental Impact Report (Leighton, 1994) in order to assess the general tech cal a d geological characteristics of the earth units that might be present at the 'te. Site Reconnaissance Site reconnaissance was performed at th site o April 1 .The purpose�f, this reconnaissance was to confirm the general g to o t site, c ck areas of possible slope instability that had been previously identifi through use of stereoscopic aerial photographic analysis, and th i pacts re ed to evelopment of road alignments extending across the site.

Typically, the landslides have on slopes with gradients of 3:1 (horizontahvertical/h:v) or steeper. These 'lan ides appear to be rotational or slumps and generally consist of mixtures of rock gments, soil, and debris from surface and underlying geologic units (Irvine, 1991). Dense vegetation is present within the landslide debris. The landslide deposits are often fractured, with cracks and voids within the landslide area, often down to the depth of the rupture surface. Additional landslides were mapped west of Happy Camp Canyon, predominantly on east- or southeast - facing, heavily vegetated slopes. - 3 - 3881198 -006 • Recent Alluvial Deposits (Oal): These sediments occur along the bottom of the active canyons that drain the area of study, and consist of gravel, sand and silt. The alluvium is unconsolidated and generally undissected. This unit is of Holocene age, deposited in the last 10,000 years. • Older Alluvial Deposits (Goal): Dissected, weakly consolidated older alluvial deposits comprise elevated terraces adjacent to the major south - flowing canyons that drain the study area. These sediments are derived from the rock units that occur n the study area, and consist of gravel and sand mixed with lesser amounts of s' and ay. Older alluvial deposits form the eastern wall of Happy'Camp Canyon and ar erally stable at existing slope gradients ranging from 1:1 to 2:1 (h:v) with on minor reas of surficial slumping (Plate 1). These older alluvial deposits are of lat leist ne e, deposited more than 10,000 years ago. • Saugus Formation (OTs): The Saugus Formation ' on the weste rti of the site, west of Happy Camp Canyon.

The California Division of Mines and Geology (1982) has prepared guidelines for geologic and seismic considerations in environmental impact reports in order to identify potential geologic hazards and assist in recognizing data needed for design analyses and development of mitigation measures. These guidelines are considered appropriate for use in this study. Using this subjective scale, distinction is made between issues that have a less than significant impact,. a potentially significa act and a significant impact related to development of the proposed road alignments. During this study, the following issues were determined to present a less- -Si cant impact to the proposed project: earthquake damage (fault movement, ground uptur , tsu mis, seiches, flooding due to dam or levee failure); loss of mineral resources (whet r b ss f a , a change in land use, or zoning restrictions); waste disposal problems (w r b a change 'n gro d -water level, disposal of excavated material, or percolation of wast mate 1); erosion, s ment on or flooding due to increased impervious surfaces; land subsid du extraction of grou wate as, oil or geothermal energy; land subsidence due to by in bon o at oxidation; Vol nic hazards (lava flow or ash fall). The discussion of ese i acts pr d in the referen report (Leighton, 1995) are applicable to the alternate roa ay ali ts. In this study, only those conditions that a judged to im rt eit r a potentially significant impact or a significant impact to the propo prof are disc in th tions that follow. 3.1 Seismic Hazards The two principal seismic bazar to ro ies in lout California are surface rupturing of. earth mate ' s alo fault tra an am t ctures and foundations due to strong ground in ons enerat during arthqu es. No known fault traces have been identified to cr e s y a a. Nnm ous tive nd poten ly a iv faults have been mapped within the southern Califo 'a regi , se v ithin a ut 60 miles (100 km) of the site. Major faults that could oduce ' ifi ground at the site include the Oak Ridge; Simi -Santa Rosa- o' Spn le, n Ca tano, Santa Susana, Arroyo Panda -Santa Ana, San Gabriel, Santa Ynez, ahbu ast, nd P e Mountain faults. Further information on each of these seismogenic so ces n be and the environmental impact report prepared for the Hidden Creek \ Ran project east he site (Leighton, 1995). The following sections detail the primary and secon ary kismic hazards to the site. A9 ,earthquake occurs when the elastic strain energy that has accumulated in the bedrock jacent to a fault is suddenly released. The energy. released propagates in the form of seismic waves that radiate great distances in all directions from the earthquake epicenter. The strong ground motion or shaking produced by these seismic waves is the primary cause of earthquake damage. How much the ground shakes at any one point depends primarily on - 5 - the earthquake magnitude, distance and direction from the earthquake source, and the local geologic conditions, which can either amplify or attenuate the earthquake waves. As with most of southern California, moderate to high intensities of ground shaking can be anticipated at the site. The property is located between the Oak Ridge fault to the north, and the Simi -Santa Rosa fault system to the south. Each of these faults is estimated capable of generating an earthquake of up to magnitude 6.9. Such events could result in horizontal ground accelerations of 0.5 to 0.7g at the site. Earthquakes on more distant faults could be expected to produce peak horizontal ground accelerations of up to 0.Sg a site. A maximum duration of ground shaking of 50 seconds is expected to occur a e sit "s a result of an earthquake on the Carrizo segment of the San Andreas fault. site is cated within seismic zone 4 of the Uniform Building Code, 1991 edition. The ref , seis c shaking at the site is considered to be a significant impact Mitigation Measures: There is no realistic way in which totally avoided; however, design of the structures in a grading codes at the time of construction can be cte of ground shaking.

Within Happy Camp Canyon, ad ali ents wi71 be located upon potentially water - bearing alluvial sediments. )und -water flow is probably to the south, parallel to the axis of the canyon. �uncghsolidated, alluvial sandy deposits that occur within Happy Camp Canyon could be Fitenle to liquefaction if perched or regional ground water is present within 50 feet of the surf ace. However, proven geotechnical construction methods can either reduce the al f or these deposits to liquefy or even eliminate the need to have to address the phenomenon of liquefaction altogether. Therefore, the potential for the occurrence of liquefaction is considered a potentially significant impact Mitigation Measures: Since the proposed road alignments are intended to be a major transportation artery from the proposed Hidden Creek Ranch across Happy Camp Canyon, the potential for damage due to liquefaction of the sediments in Happy Camp Canyon should be fully mitigated. Such mitigation measures may include deep piles or caissons, that are founded on non - liquefiable sediments, to support elevated roadways, or mechanical densification of the subsurface soils of an at -grade roadway. The area along the proposed roadway alignment west and east of Happy Camp Canyon, where localized unconsolidated alluvial deposits coupled with shallow or perched ground -water conditions may occur, may be susceptible to liquefaction. However, these shallow deposits can be remov d replaced with compacted fill as part of normal grading activities. Additionally a pi ment of subdrains along canyon bottoms will help to remove ground water t ma evelop at or above canyon bottom elevation. During the site geotechnical inv tigatio a geotechnical consultant should evaluate areas of sandy alluvial soils in th pro sed area of development that will not be removed during normal gra g era 'ons potential liquefaction and provide appropriate mitigation measures k n sary.

Areas underlain by thick accumulations of alluvium or llu . i ap pear to be more susceptible to ground lurching than bedrock Under strong se' is ound motion conditions, lurching can be expected within loose, cohesionless soils, r in cly -rich: soils- with a high moisture content. Pavements tend to be susceptible to damage by ground lurching, more heavily loaded structures appear to resist such deformation. Therefore, ground lurching due to seismic shaking is considered to pose a potentially significant impact at the site. - 7 - Mitigation Measures: Loose, cohesionless soils onsite that may be susceptible to ground lurching should be identified, removed and recompacted, if feasible. For roadways that are constructed on the ground surface, there are locations at which there is no realistic way in which the hazard of ground lurching can be totally avoided; however, construction of roadways using asphaltic concrete as opposed to other surfaces, will allow for quick, relatively easy repair or reconstruction of damaged areas. For elevated roadway structures, the affects of ground lurching can be mitigated by founding the structure on competent bearing surfaces beneath those soils susceptible to ground lurching. The affects of ground ing on the proposed roadway alignments should be evaluated during the geotech 'cal in tigation. Otherwise, deep piles or caissons may be needed to fully mitigate thi tent' impact. Residual Impact: Provided appropriate geotechnical investiga n an mitig ive measures are completed, the residual impact can be considered Class si t Initt von. 3.2 ' Slope Stability There is no established hillside grading ordi (rnce f e Ci f rpark. Grading lopes with natural gradients of 20 percent c st r ( 1 or s eper) was expressed as a concern by City of Moorpark officials during th envir nme impact report (EIR) process for the Hidden Creek Ranch pr 'ect.

These failed slopes have gradients of 3:1 (h:v) ors eper. e;t Happy Camp Canyon, east- facing and southeast- facing slopes appear to J:Z�gen %alflly sta a than west- facing slopes. On these east- and southeast- facing slopes radslid wer mapped within Saugus Formation bedrock. Bedd ng altitudes across the site were difficult to obtain during this investigation due both to the a vegetative growth covering the majority of the canyon walls and the lack of rm ry a a bedding within bedrock. Only one bedding attitude was obtained west of Happy y nyon, striking N25 °W and dipping 8°SW. 'In addition, adjacent to the western m gin of Happy Camp Canyon, geomorphic features suggested a southwesterly dipping slope. The conceptual plan for the proposed road alignments shows that the alignments only enter areas of potential slope instability where Alignments A and B converge at the western and eastern margin of Happy Camp Canyon. In' the west, based upon limited geologic structural data, bedding within the Saugus Formation has a southwesterly dip. Graded, southerly facing aIm slopes that are created during road construction could create an out -of -slope dip component leading to potentially unstable slope conditions. No information concerning bedrock structure was found to the east of Happy Camp Canyon during our site reconnaissance. Unstable slope conditions may also develop if slopes are loaded at the top, support at the toe or sides is removed, or if adequate drainage of surface and subsurface waters is not provided. Unstable slope conditions can occur in temporary cut slopes, especially if seepage associated with perched or shallow ground water conditions saturates the exposed soil materials. In trenches where bedded materials are exposed, stockpiling the excavated mat on the side of the trench where bedding dips out of the trench walls can result in urladable o6nditions.

During periods of ' tense rainfall, debris -laden runoff waters emanating from the canyons west of Happy mp Canyon could also pose a mudflow or debris flow hazard. Surficial slumping and debris flow hazards ace considered a significant impact. Mitigation Measures: Surficial landslide deposits and debris. flow deposits should either be removed or contained by retaining devices where there is potential to affect the proposed W-1 11. roadway. Because of the compressibility of these deposits, removal within development areas is generally the preferred alternative to minimize post- construction settlement. Residual Impact: Graded and ungraded slopes need to be maintained such that surficial landslides or debris flows do not develop. If surficial stability problems do develop, properly designed and constructed detention or debris collection facilities can effectively mitigate these hazards provided such facilities are maintained. Therefore, the residual impact should be considered Class U - significant mitigable. 3.2.3 Cut and Fill Slopes Geologic structure was not able to be determined in the eastern rtion the site.

Maintenance of all slopes and drainage facilities is necessary. The residual impact should be considered Class II - significant mitigabk -10- 3.3 Roadwav Foundation Stabilitv 33.1 Compressible Soils Alluvial deposits onsite mantle the floor of Happy Camp Canyon and the majority of the south - trending canyons west of Happy Camp Canyon. Based upon the results of our work for the adjoining Hidden Creek Ranch Project to the east, the near - surface alluvium within Happy Camp Canyon and all alluvium in the smaller adjacent, south - trending canyon is likely typically unconsolidated to poorly consolidated, and has medium to high per a to as a result of its coarse fraction content. These soils are considered m ratel to highly compressible. Landslide deposits are also generally considered compr sible. fluvial soils vary widely in density and porosity, but are generally considered to comp ible if subject to loading from artificial fills or structures.

Alluvial deposits at the site are ' antly coarse grained, and therefore probably have a low to moderate expansion po tial. However, based upon work performed for the proposed Hidden Creek Drive oject east of-the site (Leighton, 1994), small localized areas of highly expansive soils may occur onsite. Clays with a moderate to high expansion potential have been observed by Leighton geologists within shale and claystone interbeds of the Saugus Formation in other areas of Ventura County. The geotechnical hazard posed by soil expansivity is low to moderate in the site area and is considered a potentially significant impact - 11 - 3881198 -006 Mitigation Measures: Determination of expansivity and development of appropriate remedial measures should be performed by a geotechnical engineer prior to site development. This evaluation is usually performed during the subsurface geotechnical investigation. If expansive clay is encountered at shallow depths, it may be recommended that clay -rich soils be removed and replaced with a specified thickness of nonexpansive granular soil beneath the roadway. Mixing during grading of localized expansive soils with the more common, granular nonexpansive soils present onsite should be sufficient to mitigate this impact. Alternatively, mitigation of expansive soils can be accomplished during construction by pre- saturation of the expansive materials and/or reinforcement of the roadway base. /� Residual Impact None if expansive soil conditions are addressed apgr�priat Kat the time of construction. � �� 3.4 Erosion and Flooding 3.4.1 Erosion The erosion potential of many of the deposits at moderate to high.

To itigat the entia for increased erosion rates as a result of development, debris and /or re t tion basins may designed by the project's civil engineer to ensure that post - deve pm t runo Is are comparable to undeveloped levels, and to mitigate any debris flows at ay originate from the northem, undeveloped portions of the road alignment west of :H py mp Canyon.

Impact Maintaining a permanent erosion control program should be required. the :residual impact will be Class II - significant mitigable. - 12 - 3.4.2 Floodine The portions of Alignments A and B that traverse Happy Camp Canyon are located within a Flood Zone A, an area of a 100 -year flood. Within this area, base flood elevations and flood hazard factors have not been determined. Areas west and east of Happy Camp Canyon lie within a Flood Zone C, areas considered to be prone to minimal flooding (Federal Emergency Management Agency, 1985). The geotechnical hazard of flooding of road alignments that cross Happy Camp Canyon is therefore considered to be a significant impact - 13 - • ' 1.1-. 4.0 SUMMARY Several constraints have been identified that present either a potentially significant or significant impact to the proposed road alignments. These constraints are earthquake damage (liquefaction, landslides, differential compaction /seismic settlement, and ground shaking), slope stability, roadway foundation stability, and erosion and flooding. All constraints, ranging from those have a less than significant impact to those that have a significant impact, are listed in Ta 1, ecklist of Geotechnical Hazards and Potential Mitigation Measures. Based upon this study, and provided appropriate mitigation measures ar . corp rated to site design and construction, the three proposed alternative roadway alignmen for d Cr Drive are considered feasible. None of the proposed alternative roadway nm is is dist ctly ter from a geologic and geotechnical perspective. - 14- Plate One (oversized map) is on file and available for review during regular business hours at: City of Moorpark 799 Moorpark Avenue Moorpark, CA 93021 APPENDIX B HYDROLOGY & DRAINAGE REPORT FOR 1 Dice IQ SPRING ROAD EXTENSION ALTERNATES HAPPY CAMP CANYON SPECIFIC PLAN NO.8 CITY OF MOORPARK, CALIFORNIA PREPARED FOR: Messenger Investment Company 17512 Von Karman Irvine, Ca 92714 PREPARED BY: The Haaland Group, Inc. 351 Rolling Oaks Drive, Suite 200 Thousand Oaks, California. 91361 July 17, 1996 . 1,11# Hidden Creek Ranch Specific Plan Drainage and Hydrology Report Table of Contents Introduction Existing Conditions Existing Drainage Facilities Proposed Drainage Facilities Flood Protection Zones Hydrology Results Conclusions Appendix A Imperviousness Calculations Hydrology Routing Calculations Existing Conditions - VCFCD 1994 Computer Run Developed Conditions with Access Road - The Haaland Group, Inc. 1996 page 2 Hidden Creek Ranch Specific Plan Drainage and Hydrology Report INTRODUCTION This report has been prepared to present the study results of a preliminary hydrology analysis for the construction of conceptual access road alternaties to be constructed across the southern portion Of Happy Camp Canyon watershed for Hidden Creek Ranch, Specific Plan No. 8. EXISTING CONDITIONS Haply Camp Canyon Channel Watershed The total area of the Happy Camp Canyon watershed to the location of the proposed access road is approximately 7,383 acres. This watershed is almost entirely in a natural condition. Runoff from the area north of the Big Mountain ridgeline flows westerly and then southerly near the southwestern portion of the Specific Plan area. Runoff enters an improved channel at the north boundary of Tract 2453 near the terminus of Campus Park Drive West. This channel is under the jurisdiction of the Ventura County Flood Control District. EXISTING DRAINAGE FACH. TIES Happy Camp Channel No evidence of improvements are found with respect to the portion of the channel within the immediate area of the project-site. Originally designed and constructed in the 1960's, the Happy Camp channel exists as an open concrete trapezoidal channel north of the state highway, with transitions to R. C. double Boxes at locations where the channel crosses under streets within existing developed areas. PROPOSED DRAINAGE FAC ITIES Drainage facilities for the road construction would include only necessary culverts to allow passage of storm water flows under the proposed access road. The size and number of these culverts crossing under the access road would be determined in the design phase of the project. page 3 .cq 9232 Iv sw p wiMOORPARKI s•r •' ': ,•''• '' • _. . —._�..

Hidden Creek Ranch Specific Plan Drainage and Hydrology Report FLOOD PROTECTION ZONES The Happy Camp Channel located west of the project site is located within Insurance Zone A. Zone A defines areas of 100 -year flood; base flood elevations and flood hazard factors have not been determined. HYDROLOGY Watershed hydrology for the Happy Camp Canyon was obtained from the Ventura County Flood Cortrol District Hydrology Section. The watershed study was performed in 1994 by the Ventura County Flood Control District and will need to be verified and updated prior to final design of any storm drain structures in this watershed. The hydrology computer input data was modified by this office to model the proposed conditions with construction to the proposed access road. The proposed access road would be within subarea 120F and a portion of subarea 122A. Since the majority of the access road is within subarea ,120F, only this subarea was modified to model the improved conditions. The total area of pavement surface created by construction of the access road is approximately 7 acres. This will result in an increase in imperviousness from 0 % to 8 % within subarea 120F. Calculation of the subarea imperviousness is included as follows. page 5 Hidden Creek Ranch Specific Plan Drainage and Hydrology Report RESULTS Local Subarea Subarea 120F Area Q100 Percent Imp in acres in cfs Existing Condition 84 145 0 With Access Road 84 149 8 - Increase m Runoff 4 cfs Total Watershed to Area Q100 121AF in acres in cfs Existing Condition 7383 5229 With Access Road 7383 5232 Increase in Runoff 3 cfs CONCLUSION Locally to subarea 120F the resulting increase in runoff is only 4 cfs or 2.75 % increase in flow. . Regionally, the 3 cfs increase in runoff at subarea 121AF is only 0.06 percent in relation to the entire watershed. This minor increase in runoff will be insignificant in regards to the misting Flood Control Facilities downstream of the proposed access road.

APPENDIX C INTRODUCTION TO FLORAL AND FAUNAL SURVEY Floral components encountered during the survey were recorded in terms of relative abundance and host habitat type. Expected site use by wildlife is derived from survey information combined with documented habitat preferences of regional wildlife species that, whether or not recorded during the survey, are considered likely to include the project area within their range. Habitat designations used in this report are according to the classification system of Holland (1986). Floral taxonomy used in this report follows the Jepson Manual (Hickman 1993) and, for sensitive species, the California Native Plant Society (CNPS) Draft Rare Plant Inventory (5th Edition) (1993). Common plant names, where not available from Hickman, are taken from Munz (1974) Beauchamp (1986), Abrams (1923, 1944), and Abrams and Ferris (1951 and 1960). Vertebrates identified in the field by sight, calls, tracks, scat, or other signs are cited according to the nomenclature of Stebbins (1985) for amphibians and reptiles, AOU (1983, 1985, 1987, 1989) for birds, and Jones et al. (1991) for mammals. wnW=WW8.FF 1 Floral and Faunal Compenda TABLE 1 FLORAL COMPENDIUM' LEGEND CSS - cosastal sage scrub SCS - southern cactus scrub AS/NNG - alluvial scrub /non -native grassland NNG - non -native grassland 1►I� . • a - abundant -- ubiquitous throughout the noted community; occurs in high numbers or in large, pure stands c - common —a dominant species in the noted community; occurs in relatively high numbers f - frequent -- occurs in moderate numbers, but not a dominant element of the noted community o - occasional — occurs sporadically in the noted community; generally not an obvious or conspicu- ous component i - infrequent — occurs rarely, or only in a small portion of the noted community; often not apparent unless searched for * Non -native This is not intended as an exhaustive listing of the vegetation occurring on the site; some annual herbs or very uncommon species may not have been detected by the field survey. 2 Indicates habitat type (plant community) in which species most commonly occurs; species may occur in limited numbers or restricted localities in other communities.

This investigation involved an archival records search, a review of existing published and unpublished references on local prehistory and history, and an on -foot, intensive survey of the subject property. Archival records indicated that one previously recorded archaeological site was believed to be present on the property, CA -VEN- 1128. The survey of the study area resulted in the relocation and assessment of this site, which is located at the north - central limits of the study area. No additional archaeological sites, prehistoric or historical, were found in the study area. It is recommended that a Phase II test excavation and determination of significance be conducted on this archaeological site, if development or use is proposed for the area on or immediately surrounding this cultural resource.

This survey was intended to inventory and evaluate any known historical or prehistoric cultural resources lying within this approximately 250 gross acres study area, and to identify, record and assess previously undiscovered archaeological sites. Following the guidelines of Appendix K of the California Environmental Quality Act (CEQA), the purpose of this investigation was to provide baseline data from which a preliminary assessment of the adverse impacts to any such cultural resources could be made, should this property be developed, and to provide management recommendations for the further study or treatment of archaeological sites or localities identified within the study area. This study was undertaken by W and S Consultants, and was conducted on 29 and 30 April, 1996. David S. Whitley, Ph.D., Joseph M. Simon, and Michael Hakim were responsible for the field work portion of the study. This manuscript was prepared by D.S. Whitley and Simon. A series of procedures and studies were conducted in order to adequately inventory and evaluate the cultural resources within the study area at the Phase I level. These included: a review of published reports and studies to establish the aboriginal cultural history of the region in question; an examination of historical reports and sources to outline the history of the study zone; a compilation of existing archaeological site records and files 1 to identify known cultural resources within or adjacent to the Happy Camp Canyon study area; and a field survey to assess any such known cultural resources, as well as to identify and evaluate previously unknown or unreported archaeological sites. This report summarizes the findings and conclusions of each of these aspects of the Phase I investigation. We begin with a description of our study area, the approximately 250 gross acres lower Happy Camp Canyon regional park. We then turn to a summary of local cultural history, including both ethnography and prehistory. We also consider the previous archaeological research that has been conducted in inland Ventura County. Subsequently we summarize the results of an archaeological records search, conducted by the staff of the UCLA Institute of Archaeology, Archaeological Information Center (AIC). Next we summarize the field procedures we followed in conducting the survey of the study area, and then turn to the results of the field study. We conclude with management recommendations for the treatment of the archaeological resources present within the study zone. 2 2.0 STUDY AREA DESCRIPTION The approximately 250 gross acres Happy Camp Canyon study area lies in the lower reaches of Happy Camp Canyon, immediately above (north) of an existing suburban housing tract, and east of the termination of Broadway Avenue (Figure 1). The study area encompasses the flat and broad alluvial bottom of the canyon, along with a portion of the terraces on either side. Principle among these are terraces on the southwestern side of the study area, which represent the easternmost extension of the Somis Mesa, and terraces to the northeast, which abut Specific Plan Area #8. Historic and recent land -use changes have altered the environment considerably from what existed during prehistoric times, with the study area almost entirely currently covered by oat hay. This indicates that the the study zone was disked in the relatively recent past, resulting in the elimination of the indigenous plant life. However, as many as four major plant associations may have once covered the study area during the aboriginal period. These are chaparral, coastal sage scrub, southern oak woodlands, and riparian associations (cf. Muntz 1974). The chaparral association covers steeper slopes with poorly developed soils and xeric conditions, and is still present in isolated zones within the park. It includes the following species: California sagebrush (A rt e m i s i a californica), white sage (Salvia mellifera), black sage (S. apliana), purple or white - leaved sage (S. Leucophylla), California encilia (E n c i I i a californica), California buckwheat (Eriogonum fasciculatum), chamise (Adneostoma fasciculatum), buckbrush (Ceanothus cuneatus), scrub oak (Quercus dumosa), toyon (Heteromeles arbutifolia), mountain mahogany 3 (Cercocarpus betuloides), lemonade sumac (Rhus integrifolia) and sugar sumac (R. ovata). The coastal sage scrub community is the climax community for portions of inland coastal- southern California. It is generally composed of coast buckwheat (Eriogonum cinereum) and wild buckwheat (E. fasciculatum), along with black sage (Salvia apliana), common hazardia (Ha loopap us squarrosus), prickly phlox (Lel2todactylon californicum), yucca (Yucca whipplei) and California sagebrush (Artemisia californica) as major constituents. Although both of the above plant associations were undoubtedly of subsistence importance to the aboriginal population of the region, the third association, the southern oak woodland, may have been of primary significance in the inland zones adjacent to the coastal strip. This results because of the great importance placed on the acorn as a food staple by Native Californians (Kroeber 1925), and the rarity of this resource on the coastal side of the Santa Monica Mountains. The association is characterized by the coast live oak (Quercus lobata) and the valley oak (Q. agrifolia), but also would have included various species of native grasses. Although currently restricted in distribution, this association was probably once more widespread in the region, including in the open, lower portions of Happy Camp Canyon which compose the study area. The fourth and final plant association consists of riparian habitats, which are localized and poorly diversified woodlands found in areas of perennial moisture. They include such species as arroyo willow (Salix lasiole si), 4 mule fat (Baccharis glutinosa), willow dock (Rumex salicifolius), swamp knotweed (Polvaonum coccineum), nettle (Urtica holosericea), cocklebur (Xanthium strumarium) and rabbitsfoot grass (Polvpoaon monspeiensis). Though this plant association is limited in distribution, it can still be considered to have had significant economic importance in aboriginal times, especially in terms of the acquisition of raw materials for items like baskets, cordage and netting. A riparian habitat is still present in the middle of the study area, in a small, entrenched arroyo which bisects the canyon from north to south. 5 3.0 ETHNOGRAPHIC AND PREHISTORIC BACKGROUND 3.1 Ethnographic Background The Moorpark region, including the study area, lies within the territory of the Chumash ethnolinguistic group (Kroeber 1925). These were Hokan speaking people, who occupied the area from Topanga Canyon northwest to approximately San Luis Obispo. Because of their location in an area of early Spanish missionization, Chumash culture and lifeways were heavily disrupted prior to any modern efforts at ethnographic research, hence our knowledge of them is limited. However, based on fragmentary records and various means of inferential and analogical studies, a certain amount can be reconstructed about their way of life. The Chumash followed a hunting - gathering- fishing subsistence pattern, which incorporated a heavy reliance on maritime resources, including pelagic and littoral fishes, and shellfish. Indeed, the bountiful sea resources that they were able to exploit may have been a key factor in their evolutionary success (Landberg 1965): at the time of the arrival of the Spanish they had reached levels of population density, and complexities in social organization, unequaled worldwide by other non - farming groups (Moratto 1984:118). These included permanent coastal villages along the Channel Islands area containing as many as 1000 inhabitants (Brown 1963), as well as a hierarchical sociopolitical organization consisting of at least two major chiefdoms (Whitley and Beaudry 1991). Further, based on recent reconstructions using mission registers, the Chumash appear to be have a matrilocal, and perhaps L matrilineal, clan -based society (Johnson 1988). It is likely that the study region was a part of a large political body, probably a simple chiefdom, headquartered at Muwu. at modem Point Mugu (Whitley and Clewlow 1979). This was known as Lulapin, a domain whose limits stretched from the southeastern extreme of Chumash territory to just beyond modern Santa Barbara, at Dos Pueblos. According to oral traditions, Lulapin was ruled (and perhaps created) by a lineage of Santa Cruz Islanders; "Chumash', in fact, is a word that means "islander". Its use as the generic name for this Hokan language attests to the importance of island groups throughout the Chumash realm. 3.2 Archaeological Background Regional prehistory is best viewed in reference to a chronological scheme that has its origins in the research of D.B. Rogers (1929), working on the Channel Islands and the Santa Barbara coastline. At a later date, Rogers' scheme was modified in terminology and improved with additional and more detailed data and radiocarbon dates by W.J. Wallace (1955). Modifications have been made subsequently; notably, by King (1981) who, using an analogy with Central California chronology, proposed again a different terminology than that suggested by Wallace. However, Wallace's terminology remains intact throughout most of southern California, and easily accommodates recent refinements in the chronology. Wallace's chronology for southern coastal California includes four time periods, the earliest of which (Early Man/Big Game Hunting period) was 7 considered speculative, and thought to correlate with the end of the Pleistocene. It is likely that occupation of the southern California coastal region occurred during this early time period, particularly given that there is growing evidence for Late Pleistocene occupation of the desert portions of California (e.g., Whitley and Dorn 1988, 1993). Currently, the only evidence of such in the coastal zone has been limited to a few discoveries of fluted projectile points, found in isolated locales (e.g., Erlandson et al 1987). However, the characteristic geomorphological instability of the California coastline and Transverse Mountain Ranges, combined with the major change in erosion al/deg radational regimes . that occurred at the end of the Pleistocene, does not favor the preservation of remains from this period in inland /coastal or coastal California proper (cf. Whitley and Dom 1993). With the transition towards a modern environment, starting approximately 9 to 10 thousand years ago, however, an adaptation referred to as the Early Millingstone period (or Early Horizon) began and is evident in the archaeological record. Most sites of this stage date between 8500 and 3500 years in age, and are dominated by assemblages containing large numbers of groundstone artifacts, along with crude choppers and other core /cobble tools, including the so- called "scraper plane". This assemblage has been thought to represent an adaptation to gathered foods, especially a reliance on hard - shelled seeds. More recently, it has been suggested that scraper planes, in particular, may have served in the processing of agave (Kowta 1969; Salls 1985); that the association of groundstone and core /cobble tools represents a generalized plant processing toolkit, rather than one emphasizing hard- seeds, per se (Whitley 1979a), and one that was used in appropriate environmental settings throughout the prehistoric past. That is, that the so- called early millingstone toolkit is environmentally rather than chronologically specific and reflects localized exploitation patterns, rather than a wide - ranging adaptational strategy (Leonard 1971). However, on the coastal strip, per se, there continues to be evidence that at least some such sites date to the earlier end of the time - frame, and are generally located on terraces and mesas, above the coastal verge. Recent studies by Erlandson (1988a; see also Erlandson and Colton 1991), further, provide evidence of a significant, even if small, population of coastal hunters - gatherers in the region before 7000 years ago, or at the beginning of the Early Millingstone period. He has shown that these were neither Big Game hunters, nor specialized, hard -seed gatherers, but instead generalized foragers that relied on a variety of different kinds of terrestrial, coastal and marine resources, and that they were adapted 'to estuarine embayments that have long -since disappeared from the local environment. Further, his evidence indicates that their primary protein sources were shellfish and other marine resources. Extending a pattern first identified by Meighan (1959) on the Channel Islands, in other words, this suggests that the adaptation to the seashore is a very ancient and long -lived tradition in local prehistory. Following the Early Millingstone, a transitional stage, referred to as the Intermediate period (or Middle Horizon), occurred. It is believed to have gotten underway about 4000 to 3500 years ago, and to have lasted until about AD 1200 (cf. Arnold 1990:112). It is marked on the coast by a growing exploitation of marine resources, the appearance of the hopper E mortar and stone bowl /mortar, and a diversification and an increase in the number of chipped stone tools. Projectile points, in particular, are more common at sites than previously, while artifacts such as fish hooks and bone gorges also appear. Further, there is substantial evidence that it was at the early end of this Intermediate period that inland sites, such as those found in the Conejo Corridor on the north side of the Santa Monica Mountains (discussed below), were first established and occupied, suggesting the exploitation of more varied environments and perhaps an increase in population (Whitley and Beaudry 1991), as well as a movement of coastal sites down towards the beaches. In general, however, the Intermediate period can be argued to have set the stage for the accelerated changes that took place immediately following it. With the transition to the Late Prehistoric period at approximately A.D. 1200, following the earlier appearance of the bow and arrow (around A.D. 500) which represented a major reduction in the size of projectile points, along with certain changes in bead types, we can correlate local prehistory with Chumash society as described (even if in abbreviated form) by early chroniclers and missionaries. However, this is not to suggest that society was in any way static, for the transition to the Late Prehistoric period was marked by the evolution and eventual dominance of a sophisticated maritime economy. Further, the rise in Chumash social complexity has been shown to have been associated with the development of craft specialization, involving the use of standardized micro - drills to mass produce shell beads on Santa Cruz Island (Arnold 1987). This occurred sometime around A.D. 1200, and resulted in the Lulapin chiefdom noted previously. 10 While Moorpark study area must be viewed within this general prehistoric and ethnohistoric context, it is nonetheless true that the reconstruction of Chumash prehistory and ethnohistory have largely been based on coastal evidence. That is, sites and minor regions inland from the coast obviously vary from those on the coastal strip (lacking, for example, access to coastal and maritime resources) and therefore exhibit not only some differences in terms of general site characteristics and adaptational trajectories, but differences in general chronological parameters too (W and S Consultants 1985; Whitley 1985). The Moorpark region is located in an inland area generally referred to as the Simi Corridor. This comprises part of a series of east -west trending valleys and intervening hill systems lying northward (and therefore inland) of the Santa Monica Mountains and Conejo Corridor. It includes the Simi Valley proper, the Tierra Rejada, Little Simi and the Santa Rosa Valleys, all of which are tributary to the Calleguas Creek drainage. Although little archaeological research in the Simi Valley /Moorpark area and Simi Corridor, as well as the Santa Clara Valley to the north, has been published, the prehistory of this area may be profitably compared to that of the adjacent Conejo Corridor, located immediately to the south, and to the Santa Clara Valley, to the north. Using evidence from the Conejo Corridor and Santa Clara Valley as a model, and unlike the Chumash region in a more general sense, the first indication of aboriginal occupation in this inland area appears to date to the beginning of the Intermediate period, or from about 3500 years B.P. (W and S Consultants 1985:69, 1991; Whitley and Beaudry 1991). This comprised the initial occupations of a series of what have been termed 11 site complexes. These are agglomerations of small habitation and special purpose sites that are localized in relatively restricted areas (Whitley 1979, 1980, 1985), and are generally associated with springs or other permanent water sources. A series of site complexes have now been identified and studied in the Conejo Corridor region and, although the evidence is less complete for the Santa Clara Valley and the Simi Corridor, they are known to exist in these regions as well. For example, site complexes have been identified in the Tierra Rejada, in upper Happy Camp Canyon, and on the extreme eastern side of the Hidden Creek Ranch, in the Simi Corridor (W and S Consultants 1991, 1995), while a number are present in the Santa Clara Valley. Almost without fail, each of these complexes contains deposits or components that represent the entire temporal span of inland occupation. As well, there is no clear functional or adaptational differentiation between earlier versus later temporal components of these complexes. That is, even while there is a general tendency towards more complexity in the nature and variability of the tool assemblages towards the present, it is now clear that even some of the earlier temporal components in the region exhibit subsistence emphasizes found in the later components (W and S Consultants 1984). And this is to say that, from the initial occupation of this inland region, a very generalized foraging strategy was followed, not necessarily by every site complex in the area, but certainly by the inland occupation when considered as a whole (ibid; Whitley and Beaudry 1991). Thus, not only do we see early occupations exhibiting artifact assemblages that resemble more typically 'later' assemblages, with their 12 heavy emphasis on hunting and hunting tools, but we also see late sites very much appearing like temporally 'earlier' sites, with a dominance of groundstone tools and chopping implements (ibid). The inference that results, consequently, is that the establishment of inland sites some 3500 years ago in inland Ventura County appears to represent an effort to exploit a variety of non - coastal environments, following a number of different subsistence strategies. This point of initial exploitation and occupation may correlate with a shift to the modern climatic regime, which also appears to occur at this time (G. Smith, personal communication, 1990). Regardless of cause, however, it is apparent that it was part of a far western North American -wide expansion in population and settlement (W and S Consultants 1993). Further, it is clear that no single subsistence strategy uniquely characterized any specific time period; instead, a generalized foraging pattern appears to have held for the entirety of the prehistoric occupation of the inland area. Finally, it is worth noting the differences that are appearing between site complex distributions in the Conejo Corridor and the Santa Clara Valley, and the implications these have for the Simi Corridor generally, and the Moorpark region specifically. In The Conejo Corridor, site complex distributions are both relatively dense and surprisingly regularly spaced: generally, they are present every one to 1.5 km across the entire Conejo Corridor, apparently reflecting the widespread availability of potable water, and the high carrying capacity of the area. In the Santa Clara Valley below approximately Newhall, in contrast, site complexes are restricted to the banks of the river itself, and are tied to permanent streams flowing southwards out of the Los Padres Mountains. That is, they are much more widely- spaced, and are essentially absent in the 13 foothills on the southern side of the valley, all reflecting the limited availability of water in this drier portion of inland coastal southern California. However, a provisional interpretation is that, while the Santa Clara Valley site complexes are less numerous and more widely spaced than those in the Conejo Corridor, they are somewhat larger in size. Again, at a provisional level, it appears that the Moorpark/Simi Valley region is transitional between the densely spaced, smaller complexes characteristic of the Conejo Corridor and the very widely spaced larger complexes of the Santa Clara Valley. This suggests that archaeological sites in the Moorpark area should be localized into a relatively few areas, should show a strong association with natural water sources, and should represent relatively large concentrations of sites. 3.3 Historical Background The Moorpark region, including study area, was originally part of El Rancho Simi land grant (or, more properly, San Jose de Nuestra Senora de Altagracia y Sim(), ceded by the Spanish crown to the Santiago de la Cruz Pico family in 1795 (Havens n.d.; Thompson and West 1883:49, 389) and headquartered at the 'Simi Adobe' (at modern Strathearn Historical Park within the City of Simi Valley). Although now in Ventura County, El Rancho Simi was originally placed under the ecclesiastical jurisdiction of Mission San Fernando (Cameron 1963:5). Rancho Simi was evidently a successful enterprise until 1842, when it was purchased by Don Jose de la Guerra y Noriega, who added it to his substantial holdings that were said to stretch from Santa Barbara to San Diego (Thompson and West 1883:44; 14 Sheridan 1926:168). In 1862, this 113,009.21 acres parcel was ceded to Mr. Guerra by the U.S. Land Commission following the war with Mexico, and the property was patented on June 19, 1865 (Sheridan 1926:168; Allen 1987:3). Subsequently the rancho in general served principally for sheep grazing until purchased by eastern investors, involved in oil speculation. Because they failed to find oil, the Simi Land and Water Company was formed under the leadership of Thomas R. Bard, representing Thomas Scott of Pennsylvania, in 1887, and an eff ort was made to sell the land in parcels (Havens n.d.). In 1889, Robert Strathearn purchased 18,000 acres of Rancho Simi, including portions of what are now Moorpark. At that time, the Moorpark area constituted the western limits of the Strathearn Ranch, and thus served for livestock grazing. During the 1850s and 1860s, however, the first settlers moved into the Moorpark region (Cameron 1967:9), apparently on land peripheral to what would be the Strathearn Ranch. Whether these individuals were squatters or not is unclear from existing records, although this is likely. In the late 1880s, Fales and Louise Oliver with their eleven children began farming the area that eventually became know as Epworth (ibid:14) - the western end of 'Mesa de Somis" lying to the northwest of the lower Happy Camp Canyon study area - which was then a part of the Freeman Ranch, headquartered somewhat further to the west. Moorpark proper, meaning the area of the original old town around High Street and the railroad, was subdivided and recorded in 1900, following the reorganization of the Simi Land and Water Company, and the completion of the rail line. It constituted a portion of the earlier subdivided area know as Fremont or Fremontville, recorded in 1893, which 15 was also sometimes referred to as Little Simi. Robert and Madeline Poindexter were responsible for laying out the new township, including the planting of the California Pepper trees along High Street, and the establishment of a school site (ibid:3, 23), in anticipation of the appearance of the railroad, work for which began in 1899. Robert Poindexter served, at that time, on the board of directors of the Simi Land and Water Company. By 1901 a rail depot, warehouse, post- office, blacksmith shop, general store and barber shop had been established in Moorpark. In 1905 the school that had formerly stood on Peach Hill in Fremont was moved into town. Shortly thereafter, the Methodist Church that had been built in Epworth was moved to the corner of Walnut and Charles Streets, and the town quickly developed into an important farming community (ibid:24). The Virginia Colony, located to the southeast of downtown Moorpark and southwest of the study area, developed at about this same time. It was occupied by Hispanic ranch workers, and was named after a female preacher involved in missionary work among the Hispanic population (Triem 1985:113). By 1920, Moorpark had established itself as the apricot center of the county. Moorpark remained a rural farming community into the latter half of this century: in 1957 the population had only reached 2463 people (Cameron 1967:24). However, since that time the town's growth has become increasingly related to the suburban development of the county as a whole. It was incorporated a decade ago and has grown rapidly ever - since. The lower Happy Camp Canyon study area, per se, appears to have been W peripheral to the historical development of the region, however. The large majority of it has remained in open space and has been used for livestock and farming. Accordingly, beyond its use as a peripheral grazing area for cattle, the study area figures very little if at all directly in the history of the area. 17 4.0 ARCHAEOLOGICAL RECORD SEARCH In order to determine both if the lower Happy Camp Canyon study area had ever been systematically surveyed by archaeologists, and whether or not prehistoric and /or historical archaeological sites were known to exist on the property, an archaeological records search of the UCLA Archaeological Information Center (AIC) site files and maps was commissioned. This record search was conducted by the AIC staff on April 17, 1996. We include a copy of their records search as Appendix A of this report. According to the maps, site records and reports on file at UCLA, one prehistoric archaeological site had been recorded within the study area. Designated CA -VEN -1128, it is located in the north - central portion of the study area, in the broad open flats of the canyon. It was first recorded in 1993, and was said to consist of an area of fused shale, quartzite and rhyolite flakes, measuring approximately 150 by 120 meters in size. Furthermore, although the project area had not been surveyed in its entirety, a previous archaeological survey had been conducted within the boundaries of the study area. This comprised an examination of 283 acres located towards the central- western edge. No evidence of extant cultural resources were found in this section of the study area during this previous archaeological survey. In addition to this site, four additional sites have been recorded within a half -mile radius of the study area, suggesting that it maintains considerable archaeological significance. Moreover, one previous archaeological survey had systematically covered the study area, albeit this was completed in 1983, and two additional surveys had 18 examined portions of the lower Happy Camp Canyon area. Historical maps, consisting of the 1921 and 1941 USGS Piru 15' topographical quadrangles, were also examined in an effort to identify historical structures or features that might have existed on the property. None were found to exist within the study area, although there was development within the general Moorpark vicinity by 1921. In addition to these historical maps, we also consulted the Subdivision Map of Epworth (dated May 1893), the Subdivision Map of Fremont (April 1894), and the Subdivision Map of Moorpark (November 1900; Cameron 1967). None of these early maps showed any evidence of development extending into the study area during historical times. In summary, the records search demonstrated that the lower Happy Camp Canyon study area maintained high archaeological sensitivity. 19 5.0 ARCHAEOLOGICAL FIELD SURVEY An intensive, Phase I archaeological field survey was conducted on the approximately 250 gross acres lower Happy Camp Canyon study area on April 29 and 30, 1996. David S. Whitley, Ph.D., Joseph M. Simon and Michael Hakim served as the survey crew during this study. Field procedures involved spacing the crew at approximately 15 to 20 meter intervals and then walking the property in transects, generally following the contours of the local topography. The groundsurface was examined during these transects to identify archaeological specimens in the form of worked artifacts, or archaeological indicators, which might consist of specimens of shellfish, bone or waste lithic material resulting from the tool- making process. During the survey special attention was paid to geomorphological conditions that affect the preservation of archaeological remains. Road or bank -cuts that expose subsurface stratigraphy, for example, along with stable geomorphic and depositional environments, were carefully examined for evidence of cultural remains. Given the geomorphology of the study area, these included the foots of slopes, as likely spots for subsurface deposition, and knolltops and flat open ridges as areas also likely to contain cultural resources. Furthermore, rodent backdirt piles were carefully examined inasmuch as they can reveal the presence of buried archaeological deposits. In contrast, slopes of greater than about 25% grade, where erosional and gravitational forces would preclude the preservation of archaeological remains, were less intensively examined, C41ifomia Regional Information Center Historic Lot Angeles.

This search includes a review of all recorded historic and prehistoric archaeological sites within the project area as well as a review of all known cultural resource survey and excavation reports. In addition, we have checked our file of historic maps, the National Register of Historic Places, the California State Historic Resources Inventory, the California Points of His rical Interest, and the listing of California Historical Landmarks in the region. Th following is a discussion of our findings for the project area. PREHISTORIC RESOURCES: Three prehistoric sites, CA -VEN -672, CA -VEN -1127, and CA -VEN -1128, have been identified within a one -half mile radius of the project area (see enclosed map). One, CA -VEN -1128, is located within the project area. HISTORIC RESOURCES: Two historic archaeological sites have been identified within a one -half mile radius of the project area (see enclosed map). These are CA- VEN -1264H and CA- VEN- 1265H. None of these are located within the project area. Inspection of our historic maps -- Piru (1921 and 1941) 15' series -- indicates that by 1921, Happy Camp Canyon had been named. The communities of Moorpark to the southwest of the canyon, and Epworth to the northwest of the canyon, had been established. A primary road had been constructed along the lower half of Happy Camp Canyon. A few primary roads branched off in the southern part of the canyon and seem to follow present day State Route 118 and Los Angeles Avenue. An unimproved road was present in the upper part of the canyon. A few unimproved roads branched off the northern part of the canyon. Several intermittent streams were present in the general area of Happy Camp Canyon. The Southern Pacific Railroad had been constructed to the south of the project area following the present day course of the railroad. By 1941, the general area was only slightly more developed. State Route 118 had been constructed. The map indicates that the road along Happy Camp Canyon was unimproved. Vineyards had been established along this unimproved road A jeep trail branched off to the east. Several unimproved roads branched off to the north. Orchards were established along State Route 118, east of Happy Camp Canyon.

In particular, ground cover was still dense in many areas, with the valley bottom in particular covered by a dense growth of oat hay. This greatly impeded the visibility of the groundsurface. However, careful attention to the commonly occurring rodent backdirt piles and holes, combined with frequent clearing of the grass to expose the soil below, resulted in reasonable coverage of the study area. The survey resulted in the relocation of the previously recorded archaeological site, CA -VEN -1128. This was found in its mapped location in the central northernmost portion of the study area, along the eastern side of the small arroyo which bisects the canyon from north to south. Fused shale shatter and float was noted in the site area and, while we failed to find the artifacts recorded as present at this site at the time of original discovery, this may be due to the dense cover of oat hay present at this location. Nonetheless, surface indications suggest that the site is approximately as large as mapped. Given the alluvial nature of the environment in which the site is located, it seems unlikely that a subsurface deposit is present at this locale; that is, it is most likely a surface lithic scatter. The site does not appear to have been disturbed beyond the disturbance, principally from historical disking, which existed at the time of its original recording. The site record for this cultural resource is included as Appendix B to this report. No other cultural resources of any kind, prehistoric of historical, were 22 found within the study area. Given that the majority of the study area sits within an active alluvial flood plain, and the fact that it has now been surveyed twice in its entirety, the likelihood that additional sites may be present but were overlooked during the survey seems very unlikely. 23 7.0 CONCLUSIONS AND RECOMMENDATIONS An intensive Phase I archaeological survey and cultural resources assessment of the lower Happy Camp Canyon study area, Moorpark, Ventura County, California, was conducted by W and S Consultants. This study involved a literature, maps and records review of the prehistory, history and status of archaeological research in the region, and an intensive on- foot survey of the approximately 250 gross acres study area. One previously recorded prehistoric archaeological site was identified during the background records search within the study area, CA -VEN -1128. During the fieldwork phase of the study, this site was relocated and evaluated. It was found to be intact, and is believed to most likely represent a surface lithic scatter. No new or additional archaeological sites of any kind were found during the survey of the project area. 7.1 Preliminary Recommendations Given the presence of prehistoric archaeological site CA -VEN -1128 within the lower Happy Camp Canyon study area, it is apparent that development within the specific area of this site has the potential to result in adverse impacts to cultural resources. Following the guidelines outlined in Appendix K of the California Environmental Quality Act, accordingly, we recommend that Phase II test excavations and determinations of significance be conducted at this site, if any development or use is proposed for the area on or immediately around this archaeological site. 24 These test excavations should be undertaken to provide baseline data from which an accurate estimate of the size, nature and significance of this cultural resource can be made. Further, based on the results of the Phase II study, final recommendations for the management and disposition of this site can be made. 25 8.0 CITED REFERENCES Allen, P. 1987 Historical Overview of the McCrea Ranch Property.

(Leighton) has prepared this report to present a preliminary evaluation of the potential presence of faulting and/or zone of deformation in the Specific Plan 8 area, based upon the recent identification of blind thrust faulting and zones of deformation in the Specific Plan 2 area to the west. The purpose of this study was to review available data and provide input for the geotechnical portion of the Environmental Impact Report for Specific Plan 8 concerning the potential presence and activity of faults and/or zones of deformation. 2. Scope of Work As discussed in our proposal to you dated August 28, 1997 Leighton has conducted the following scope of work: a) Attendance at a kick -off meeting with City of Moorpark Planning Department officials; b) Review of available geologic reports and City of Moorpark geologic review letters for the Specific Plan 2 area (see Appendix A); c) Review of regional geologic/topographic maps and the geologic/topographic map for the Specific Plan 8 area; d) Review of aerial photographs for geomorphic lineations that may be indicative of a fault trace or zone of folding/deformation caused by a blind fault. We were assisted in this task by Dr. Tom Rockwell of Earth Consultants International, an affiliate company of Leighton; e) Interview the City of Moorpark geologic consultant and the geologic consultant for Specific Plan 2; f) Interview representatives of Earth Consultants International (ECI) and Fugro Incorporated, both of whom had the opportunity to review field exposures in the Specific Plan 2 area; g) Site reconnaissance of the Specific Plan 8 area; h) Meeting with City of Moorpark Planning Department officials to discuss findings; and, (8 18) 707 -8320 • (800) 273 -5552 31344 VIA COLINAS, SUITE 102, WESTLAKE VILLAGE, CA 91362 FAX (818) 707 -7280 3881198-011 i) Preparation of this addendum report to the geotechnical section of the Environmental Impact Report for Specific Plan 8. The scope of work does not include response to review comments by the City of Moorpark's geotechnical consultant 3. Site Description a) The Specific Plan 8 area is located in the southern foothills of Big Mountain, in Ventura County , California (see Figure 1). The subject site is bounded to the south by Moorpark Community College, to the west by Happy Camp Canyon, and to the east by the Simi West (Moorpark) Oil Field. The site consists of approximately 4,200 ± acres of predominantly ranch land which is presently within an unincorporated area of Ventura County. The subject site is characterizedby a southward- sloping plateau that is dissected by several gentle- to steep- walled, generally north - /south- trending canyons. Elevations at the subject site vary from a topographic high of 2,234 feet above mean sea level (msl) on the northern portion to a topographic low of 660 feet above msl in the southern portion of the site. In general, the natural slope gradients at the subject site range from 2:1 to 1:1 (horizontal to vertical/h:v), with locally near - vertical slopes on the western portion of the site. b) Natural vegetation at the site consists primarily of low grasses, sage, chaparral, and cacti. Oak trees occur locally, primarily in the canyons and tributary drainages. 4. B2ckLyround Pacific Materials Laboratory,inc. (PML) conducted an extensive and detailed fault exploration during a Tentative Tract Map study in the Specific Plan 2 area, which is generally southwest of Specific Plan 8 (PML, 1997c). During this exploration, PML identified a zone of deformation caused by a blind thrust fault referred to as the "Northern Site Area Thrust ". This fault was inferred to be active based on interpretations of field and analytical data collected by PML (PML, 1996b). This blind thrust fault was interpreted to be a projection of bedding planes from the underlying Tertiary bedrock, in which its surface manifestation is only shown by the deformation of the Quaternary strata. The identification and analysis of the fault was aided by the existence of a well- preserved alluvial surface on the site. The "Northern Site Area Thrust" fault was found to have a general trend to the northeast. Some geomorphic expression to the east of Specific Plan 2 suggested that this fault may cross Happy Camp Canyon and extend toward Specific Plan 8. The blind thrust faults on the Specific Plan 2 site have been interpreted by PML to be bedding plane faults, thus, they are not considered to be seismogenic structures (e.g. they are not considered capable of generating earthquakes). Rather, activity on the blind thrusts is believed to occur co-seismically, possibly during moderate to large earthquakes on the nearby Oak Ridge or Simi -Santa Rosa faults which regionally bracket the site. The blind thrust faults and associated zones of deformation discovered on the Specific Plan 2 property are considered to represent potential ground rupture and ground deformation hazards. Ground rupture hazards presented by seismogenic faults are typically regulated by the Alquist -Priolo Earthquake Fault Zoning Act While we are not certain whether the blind thrust faults at Specific Plan 2 will be zoned by the State, it has been typical practice by consultants to zone faults which are considered to have the potential for co- seismic ground rupture. Ground deformation hazards (i.e., upwarping of the ground surface, typically in the hanging wall of the fault, as opposed to ground rupture) are not regulated by the Alquist- I f l l Y•� ~� •� R V r. 1 i t'� —• �t 1 ' .� • �'1 r kf f VJ ( r •,1 r'' 1 t �� I� t �,, �` f 1`° • J ,rr ,'�• t, i 1••i,.•.•r� •� Y � �ry�, �� �i It w;... 1 / Sul , 1, u �, 1 r'_Z� �/`��'S k, r • � ;� . {. � ,r�:�4, f -;•'�- .,11 ,J�• jr /�.,:! .L,! i• � ,.- •3.� "• PIZ',�`y�;..�' 1, 1 f /J.. bbl � TO/ �I 'v - -�• � �� 1 � 1. .. ` 1 , � •I � , P � � 1 (• r 7 \ ! l •�t:1 1 .�: �If, �, ► ��j �j 11� f ` � � •./ r. 1 �.r� �''t� `'-.► � `;r ', / ' � Pte; 'r; �l`�� ' ,� t -•� /'l �,,' j1�,t). ;,,T � ,-t,�1 f/f �� �' :; G:�� i� �� � P �I SUBJECT �,t 1. ,../ �G� ,� r�L�1�f _�r ,�, �y %�(��•.�r�' ,� 11 (Jt•U�I i ('i�R fI. ), •e ,� �� '�',1 :- "�L`)`NWI!tl - C_7:�'J/�.r),� 1 � 'A,i! ...., �•, ...:,1.... «I. ..,..L,r r'�,5�f\�i����:�/)..��L•' /1 '_ r'r1, 111 q , i!� 1 �+I IN I • y �'I r1 ��y.Y:�46 \� � !II II- • '�' '- .., �.f "(r..,' �. _.1 WARK ILLEGE �� ..t _'�,-�; ��;,�f •jam r:, �.��7�� '1 rfi t• 1 �r' f tom- r , � ; ••I IIASE MAP: U.S.G.S. 7.5 MINUTE SIMI QUADMNGLE, PHOTOdEVISFO 1969 SITE LOCATION MAP SPECIFIC PLAN 8 AREA/HIDDEN CREEK RANCH PROJECT MOORPARK, VENTURA COUNTY, CALIFORNIA Project No. X001190 -011 1 Scale As S11ow11 — Eng./Geol.

However, we understand that the Division of Mines and Geology is currently reviewing ground deformation hazards in order to develop legislation for the mitigation of these hazards. 5. Findinos a) Review of Stereo ra hic Aerial Photo ra hs Stereographic aerial photograph of the site for the years 1953, I983, and 1993 as well as four 1993 oblique frames were carefully reviewed by Leighton and ECI. Selected portions of frames AXI -11 K -14, AXI- IlK -15. AXI- 11K -17, AXI -3K-41 through AXI -3K-43 of the 1953 aerial photographs were enlarged 400% to provide a more detailed review of geomorphic features on Happy Camp Canyon and the western portion of Specific Plan 8 area. The lineament associated with the "Northern Site Area Thrust' was identified on aerial photographs and traced to the easterly edge of Happy Camp Canyon. However, this lineament could not be observed on the eastern side of Happy Camp Canyon or in Specific Plan 8 area, either because it does not exist or it is not observable due to a lack of well- preserved alluvial surfaces and geomorphic expression of such lineament. An east -west trending lineament was also observed just north of Specific Plan 2 area. This lineament was visible due to a sudden change in topographic relief from a relatively flat plateau of younger alluvium just south of Broadway (State Route 23) to the elevated hills just north of the Specific Plan 2 area. This feature was also mapped by the California Division of Mines and Geology (CDMG, 1973) as a concealed fault and is also identified in the City of Moorpark's Seismic Safety element (City of Moorpark, 1987) as the Fairview Fault. This fault has not been projected to Happy Camp Canyon in either reference. A generally similar trending lineament was observed between Happy Camp Canyon and Specific Plan 8 area (see Plate 1); however, this lineament dies out immediately west of the Specific Plan 8 area. Another anomalous feature observed in the aerial photographs was an east -west trending canyon at the southwest portion of the subject site (south of the proposed high school, generally between Planning Unit 39C to the north and Planning Units 32 and 33 to the south). This drainage feature is considered anomalous because it is east -west trending in an area dominated by north- south- trending drainages.' This feature could not be traced eas: or west of the aforementioned Planning Units. b) Site Reconnaissance A site reconnaissance was conducted on August 10 1997, by a Leighton geologist. The easterly edge of Specific Plan 2 area, Happy Camp Canyon, and the westerly edge of Specific Plan 8 area were reconnoitered to corroborate the data obtained from the aerial -photo review and to try to determine if there was any other geomorphic expression or exposures of the "Northern Site Area Trust" or any other structural lineaments transecting from Specific Plan 2 area into the subject site. During the site reconnaissance, it was observed that a relatively flat plateau, just east and above of Happy Camp Canyon, had a very distinctive riser (break in slope) in the topography. This particular feature has an east -west trend and appears to die out as it approaches the westerly edge of Specific .3881198-011 Plan 8. Unfortunately, most of the westerly edge topography of Specific Plan 8 is currently covered by avocado and citrus groves. However, no distinctive changes in topography were observed to the east of the avocado and citrus groves, in the area in which the topographic riser feature would have projected. Very limited structural data was collected during this site reconnaissance, due to the lack of bedrock exposures. No other significant features were observed other than the features observed during the aerial photograph review. 6. Conclusions a) Based on the findings obtained during this preliminary fault evaluation, it is Leighton's conclusion that the lineaments associated with the "Northern Site Area Thrust" and the east -west trending feature identified by the CDMG and the City's Seismic Safety document (aka "Fairview Fault ") which we observed in the aerial photograph review were not observed (based on topography) to transect the Specific Plan 8 area. b) The lack of geomorphic expression and well - preserved alluvial surfaces on the Specific Plan 8 site makes it very difficult to project the "Northern Site Area Thrust" into Specific Plan 8 area. However, the potential existence of this feature within Specific Plan 8 area could not be ruled out and further geotechnical investigation will be required prior to site development. c) If active faults or zones of deformation are found during future geotechnical investigation, mitigative measures may include one or more of the following: • Setback zones (restricted use or no build zones) where ground rupture may be a hazard; • Reinforced foundations, such as post- tensioned slabs, to mitigate the impacts of any ground deformation that might occur during the life of the project; • Grading mitigation, including geogrid - reinforced fills as well as possible removal and replacement with reinforced fill, of faults or deformation zones in cut areas; d) Based on our review of the specific plan, there appears to be design flexibility to accommodate mitigative measures required if active faulting or deformation is found within the proposed development area of Specific Plan S. 7. Recommendations a) Excavate trenches in areas where identified lineaments may project onto the Specific Plan 8 site. This work should be completed during the preliminary geotechnical investigation for the site for a Tentative Tract Map study. It should be noted that, with the exception of the lineament between Planning Unit 39C and Planning Units 32133, the lineaments occur west of the Specific Plan 8 property. Therefore, the trenches for lineaments west of Specific Plan 8 should be excavated as near as possible to the western property boundary of Specific Plan 8, as dictated by the terrain in the areas where projections of the lineaments onto the property occur. 388119"11 b) If active faulting or deformation is observed in the trenches, then the certified engineering geologist and the geotechnical engineer should provide specific mitigative recommendations for site development, as appropriate.

Smith 11/2197 DeAnition A Phase I Environmental Site Assessment (ESA) is a documentation process that involves investigating the previous history of uses of a property and surrounding properties, contents of agency files and records/permits, and recorded incidences of hazardous substance releases to determine the potential presence of hazardous substances or contaminants. Current uses of the property and surrounding areas are considered during the Phase I ESA to determine if there are ongoing releases, or potential releases, from activities on the site or vicinity. A Phase I ESA does not typically involve soil or water sampling to detect potential contamination; if warranted by the findings of the Phase I, such sampling occurs in a subsequent assessment, referred to as a Phase II ESA if the findings of the sampling conducted in a Phase II warrant removal or dean up actions, these are conducted through a Phase III ESA, which typically requires review and approval of appropriate regulatory agencies such as County Health Departments, California Regional Water Quality Control Boards, or the U.S. Environmental Protection Agency. Federal and state laws and regulations govern the cleanup of contamination from hazardous substances. The federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or Superfund) specifies the contaminants that are considered hazardous and for which landowners could be held liable for cleanup under CERCLA requirements. While petroleum products are not considered to be hazardous substances by CERCLA, other federal laws such as the Resource Conservation and Recovery Act (RCRA, 42 United States Code, Section 6901 et seq.), that among other considerations, governs the generation, transportation, treatment and storage of hazardous substances, and other state and local regulations do consider petroleum products to be potentially hazardous to the environment. Uses of Phase I Environmentid Site Assessment (ESA) Phase I ESAs are typically used to provide purchasers of real estate with the opportunity to use the 'Innocent landowner defense' provided by the CERCLA [42 USC 9601(35) and 9607 (b)(3)J if property they purchase is later found to be contaminated.. One of the key requirements to qualify for this legal defense is for the prospective purchaser to conduct *all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice': What constitutes 'appropriate inquiry' depends on the particular property, the knowledge /sophistication of the prospective purchaser etc Contents Many financial institutions have their own requirements for conducting Phase I ESAs on properties that they are considering for real estate purchase/refinance loans. While variations exist, the requirements of most financial institutions either specify use of, or incorporate provisions of the American Society for Testing and Materials (ASTM) Standard E 1527, 'Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process'. The factors specified in ASTM Standard E 1527 consist of the following: Description of the Property • location and legal description • site and vicinity characteristics • description of site improvements 11/05/1997 18:00 8187077280 GTG COMPANIES PAGE a5 • current/past uses of the property and adjacent properties Records Review information from Site Reconnaissance and Interview Findings and Conclusions Preparing a Phase I ESA that addresses the above factors requires a site visit, research involving review Of aerial photographs, reviewing agency databases regarding hazardous substance releases or enforcement actions, interviews with regulatory agency personnel, and evaluation of the results of these inquiries. If the Phase I ESA investigations suggest that current or past activities onsite or on adjacent properties might have resulted in a release of a hazardous substances onto or beneath the property, further studies may be recommended to collect soil or water samples to determine if such a release has occurred. These subsequent investigations would be documented in a phase 11 ESA. The findings of a Phase It ESA may determine that cleanup or remediation activities are necessary, these are then conducted, under regulatory agency requirements, through a Phase III ESA Appropriate Level of Environmentat Site Assesamer is under CEQA ESAs are not required by the CEQA Guidelines. However, Appendix I of the Guidelines (Environmental Checklist Form) , under the Hazards category, asks about whether proposed projects would involve: a) a risk of accidental explosion or release of hazardous substances (including but not limited to: oil, pesticides, chemicals, or radiation); and d) exposure of people to existing sources of potential health hazards. If not already completed as part of a real estate transaction involving the site for which an SIR is being prepared, a Phase I ESA could be used to provide the information suggested by the environmental checklist forth. For most project level EIRs, a Phase 1 ESA is an appropriate level of documentation to address the Potential health risks or safety impaft that might result from hazardous substances on the property. This is especially true if the Phase I ESA findings indicate that past and current uses of the property do not indicate use or disposal of hazardous substances. However, if a Phase I ESA being used in an EIR includes recommendations for subsequent sampling of soil, ground or surface waters, or testing of other materials (e.g., suspected asbestos containing materials) found onsite, the results of the Phase 11 ESA could be incorporated into the EIR if available. If a Phase II ESA has been recommended but not initiated during the EIR preparation process, local decision makers must then considp¢r if the findings of the Phase II ESA might alter the decision they are considering for the proposed projel:L For example, if a Phase II ESA conducted after a project was approved were to discover contamination of groundwater that the proposed project planned to use as a dornesdc water supply for future residents, the project as approved might be infeasible. The potential for such an example to exist in the real world does not necessarily require that a Phase 11 ESA must be completed before a decision is made on a proposed project and EIR. A decision making body could require, as a condition of project approval, that a Phase It ESA be completed and its recommendations implemented to the satisfaction of the applicable regulatory agency (e.g., County Health Department and/or California Regional Water Quality Control Board) prior to issuance of a grading permit for the Proposed project. This approach provides decision makers and the community with assurances that potential hazardous materials issues are satisfactorily addressed before projects are implemented. Hidden Creek Ranch Specific Plan Supplemental Information SECTION 6 AIR QUALITY ISSUES r From: JNi Environmental Consult, LLC at O (319) 454 1858 0 11 -Z4 -97 86:42 pm 6 88Z of 883 HIDDEN CREEK RANCH PROJECT - RELATED CO CONCENTRATIONS JHA Environmental Consultants remodeled the carbon monoxide (CO) concentrations at the New Los Angeles Avenue /Science Drive intersection for the year 2010. This is the location in the DEIR where the analysis showed the highest CO concentrations in 2010 of any intersection impacted by the project (35.6 ppm one -hour, with addition of the highest concentration which was monitored in Simi Valley in 1993 and 23.1 ppm eight -hour, with addition of the highest eight -hour CO concentration modeled in Simi Valley that year). Both predicted concentrations would exceed state and federal one -hour and eight -hour CO standards. The analysis of this intersection was redone using current approved emission factors, which reflect CO tailpipe controls adopted by the California Air Resources Board, which went into effect in 1993, and the now - mandated wintertime use of oxygenated fuels. Neither of these controls were included in the emission factors available in 1993 when the EIR analysis was conducted. The revised analysis also used the percentage of cold starts to hot starts recommended in the new CO protocols issued in 1996 by Caltrans for use statewide in conducting intersection analyses. In addition, the revised analysis used the roadway lane configuration in 2010 after mitigation. The analysis in the DEIR used existing configurations to better compare all existing and future conditions under worst case conditions. However, the mitigated roadway configuration represents conditions as they will actually be and more accurately defines future air quality. Roadway modifications for other intersections will be similarly beneficial. For example, a right turn lane at Campus and Collins in 2010 will move receptors farther away from through traffic and reduce projected peak CO concentrations at that intersection. In all other respects, the revised analysis used the same data as input to the model as were used in the original analysis. Below are the old and new projected concentrations for comparison. The revised analysis includes 1996 Simi Valley background concentrations. It is important to note that CO concentrations are expected to decrease throughout Ventura County, as in the rest of the state, as older cars are replaced by newer vehicles with the strict tailpipe exhaust standards. These controls will result in lowered CO concentrations, even with increased traffic.

On behalf of the Calleguas Municipal Water District (Calleguas), I offer the following comments which address water supply reliability, in general, as well as the two specific water supply - related issues highlighted in EDC's letter -- Calleguas' Las Posas Basin Aquifer Storage and Recovery project and the potential use of recycled water. Imported Water Reliability Calleguas is the principal source of water for a large portion of southern Ve.nti_Ira rni Inty. Calleguas is a wholesale supplier of imported State water purchased from the Metropolitan Water District of Southern California (MWD). MWD and Calleguas are planning for future demographic growth within their service areas and the associated increase in demand for both potable and non - potable water. Based on recent master planning efforts, which incorporated demand projections provided by Calleguas purveyors, Calleguas projects that water demand within its service area will increase 55% over a 25 -year period from 1995 through the year 2020, Given that water demand projections provided by Ventura County Water Works District No.1 were based on the City of Moorpark's growth forecasts, water demands for the Hidden Creek Ranch project were included within Calleguas' master plan. To ensure future water supply reliability for its service area, and for that matter all of southern California, Calleguas is working in coordination with MWD and other MWD member agencies on a variety of water management programs. One example of these efforts is the "Monterey Agreement" of 1994 which lead to key alterations in the State Water Project contract. Under — RECEIVED — November 24, 1997 Ms. Deborah Traffenstedt Page 2 the revised provisions of the agreement, the certainty of water deliveries for MWD (the largest entitlement holder of SWP water) is significantly increased as annual water allocations are now to based on contract entitlements rather than the yearly requests submitted by contractors. Additionally, the agreement provides increased opportunities for SWP contractors to store surplus water supplies in State reservoirs and other external facilities for later use to meet drought demands. Calleguas also "participated in MVVD's recent Integrated Resources Planning (IRP) process. This effort identified the water resources necessary to achieve MWD's reliability goal to meet 100% of the demand for wholesale water supplies within their service area. On a local level, Calleguas has initiated a comprehensive capital improvement program. This program includes the development of a variety of local water management projects including conjunctive use facilities and recycled water systems that will virtually "drought - proof" the region By reducing the region's dependence on imported water deliveries, these programs will considerably enhance water supply reliability for the entire region. Among Calleguas' more notable projects is the Las Posas Basin Aquifer Storage and Recovery Project. This project will enable pre - delivery and subsurface storage of more than 100,C00 acre feet of imported State water in the Lower Aquifer System of the Las Poses Groundwater Basin. When surplus supplies of State water are available, water will be stored by Calleguas and later pumped to meet seasonal, drought, and emergency demands. As a complement to additional storage facilities, Calleguas is actively involved in implementing a number of recycled water programs throughout its service area. These programs will provide an alternative water source and lead to more efficient use of valuable imported supplies. The collective yield of these projects is on the order of 30,000 acre feet per year -- equivalent to nearly one -third of Calleguas' annual imported water deliveries. Calleguas is currently pursuing federal and state funding for develorpmen4 of a regional water rocrciing project that -will reciai,,, wastewater effluent from nearly every treatment facility within its service area. Given the implementation of various programs identified in its master plan and water management measures on state, regional, and local levels, Calleguas expects to reliably meet all service area demands through its master planning horizon of 2020. EDC's comments on the Las Posas Basin r�oiect EDC's comments with respect to the value of the Las Posas program are likely the result of a lack of understanding of the project and its operation. EDC's inference that Calleguas has essentially discaunted the effects of drought cycles on the operation on the Las Posas project is incorrect. Indeed, the primary objective of the project is to provide a water supply buffer in the event of future water shortages. In designing the program, Calleguas factored in "Fill and Draft" patterns that consider varying hydrologic cycles that included wet, normal, and dry periods. November 24, 1997 Ms. Deborah Traffenstedt Page 3 EDC's comment regarding Calleguas' purported assumption "that a drought will not come and prevent Calleguas from constantly refilling the aquifer... unfounded. Moreover, it will not be necessary to "constantly" refill the aquifer given that the intent of the project is to store a substantial volume of water for long -term needs, not to fully cycle the storage on an annual or short -term basis. EDC also calls attention to the fact that a north/south tra -dinq f3U't asser:tial!y divides the Ncrth Las Posas Basin inio two distinct geologic units. EDC claims that such a division reduces the value of the Las Posas project by precluding the utilization of the entire aquifer for storage. For clarification, Calleguas assisted in the identification of the fault in the early planning stages of the project and has incorporated this condition into project design. Contrary to EDC's assertion that the fault reduces the viability of the project, Calleguas regards the fault as a benefit in that it will provide a very effective barrier for water stored under the program. In the absence of the fault, Calleguas' stored water would likely migrate to the western extent of the Las Posas Basin and be lost to the adjoining Oxnard Plain Basin. Furthermore. storage capacity east of the fault is more than adequate to provide the necessary storage for the project. To date, with only limited facilities in place, Calleguas has stored nearly 30,000 acre feet of water within the Las Posas through an "in4eu" storage program. Under this program, basin well operators received imported water in lieu of pumping groundwater. The right to the volume of groundwater that would have normally been produced was transferred by the participating well operators to Calleguas' storage account with the Fox Canyon Groundwater Management Agency. The benefits of the Las Posas program are indeed invaluable and irrefutable. In addition to providing greater water reliability for the region through increased independence from imported supplies, the project offers Calleguas greater flexibility in operating its distribution system as well as an iicr-a -ed measure of system redundancy vdhich is -;ritical for purveyors of aSeii�1 `' 81 public services such as water. The project will also benefit existing well operators as groundwater levels are stabilized and increased thus reducing pumping lifts and associated power costs. !_DC's comments on the potential use of reclaimed water from Simi Valley In its conclusion, EDC states that "... any impacts on groundwater supplies from the intention of the City of Simi Valley to sell its reclaimed water, rather than allowing it to percolate into the groundwater beneath Arroyo Simi." must first be "more closely examined" in the EIR prepared for the project. The EDC is seemingly unaware of the City of Simi Valley's existing right to reclaim up to 4,700 acre.feet of water from the Simi Valley Water Quality Control Plant. On June 19, 1996, the State Water Resources Control Board issued an order approving the City of Simi Valley's application requesting "a change in place of use, and purpose of use" of the facility's treated wastewater. November 24, 1997 Ms. Deborah Traffenstedt Page 4 I trust the foregoing information satisfies your needs on this matter.

Mayor Hunter asked this question at the November 12 public hearing and I was unable to provide a specific answer at that time. The communication from Mr. Austin accurately conveys calculations that I agree with regarding the statutory fees and the estimated costs to be borne by Messenger. Please call me at the above number if you require additional information. Thank you. Sinc y 4 Thomas G. Duffy,, B District Superintend( TGD:ah cc: M.U.S.D.
