Bobardt, Community Development ' eEtor Prepared by: Joseph Fiss, Principal Planner DATE: June 12, 2012 (CC Meeting of 6/20/12) SUBJECT: Consider Draft Program Environmental Impact Report for the Camrosa Water District Integrated Facilities Master Plan Project SUMMARY/BACKGROUND On May 4, 2012, the Camrosa Water District (CWD) acting in the capacity of "Lead Agency" under the California Environmental Quality Act (CEQA) circulated a Notice of Availability for the Draft Program Environmental Impact Report (DPEIR) for the Camrosa Water District Integrated Facilities Master Plan Project (CWD-IFMP) (Attachment 1). Comments are due on July 6, 2012. DISCUSSION The CWD-IFMP project evaluates CWD's ability to meet its mission through the year 2035 and to begin planning for the capital requirement to accomplish the task. The DPEIR has been prepared to evaluate specific environmental impacts associated with the proposed CWD-IFMP. CWD is the Lead Agency for the environmental review and, after the comment/response process, is the certifying agency for the Final EIR. Staff has reviewed the DPEIR and determined that there are no issues associated with the Integrated Facilities Master Plan that would affect Moorpark. It does not appear that any of the areas considered for proposed new facilities could create significant visual impacts on Moorpark residents. In addition, the DPEIR does not indicate any changes to water rights or other direct impacts to the 80-acre parcel owned by the City in the Tierra Rejada Valley, which is within the service area of CWD. The Executive Summary of the DPEIR is attached (Attachment 2). Staff does not find the need to comment on this Draft Program EIR. 429 Honorable City Council June 20, 2012 Page 2 FISCAL IMPACT None.

This document has been prepared in accordance with, and pursuant to, CEQA, as amended; Public Resources Code, Sections 21000-21177; and the "Guidelines for Implementation of the California Environmental Quality Act" (State CEQA Guidelines) as amended, California Code of Regulations, Title 14, Chapter 3, 15000-15387.the California Environmental Quality Act (CEQA). Proiect Location and Description: The project is located within the CWD Service Area, situated in the southern portion of Ventura County, surrounded by the Cities of Camarillo, Simi Valley, Moorpark, Thousand Oaks, and unincorporated areas of Ventura County. Geographically, CWD is bounded by Calleguas Creek to the west, the Las Posas Hills to the north, the Simi Hills to the east and the Conejo Hills to the south. These features also help define the Tierra Rejada, Santa Rosa, and Pleasant Valleys. The CWD-IFMP project evaluates CWD's ability to meet its mission through the year 2035 and to begin planning for the capital requirements to accomplish the task. The evaluation contained in this plan was based on the latest population projections, land development trends, and water and wastewater demand forecasts available to CWD. The resulting recommendations are intended to serve as the roadmap for implementing the major capital improvements needed by CWD to serve both potable and non-potable water and sanitary service demands to the year 2035 and beyond. CC ATTACHMENT 1 431 Page 2 The CWD-IFMP accommodates the CWD's potable water, non-potable surface water, recycled water distribution systems and the wastewater collection and treatment facilities within the Service Area. The CWD-IFMP addresses issues that affect the long-term quality, reliability, and affordability of CWD's water and sanitary services. The CWD-IFMP strives to maximize the delivery of non-potable water and promote development of new, local supplies of both potable and non-potable water. It anticipates new water quality standards for both water service and wastewater discharge and recognizes that wastewater recycling must be increased to avoid discharge into the environment. The CWD-IFMP promotes regional cooperation in meeting challenges shared by both CWD and its neighbors, and seeks to optimize the regional benefit from capital construction. Finally, the CWD-IFMP recognizes that CWD must prepare now for future infrastructure replacement to guarantee equity in financing the capital replacement needs of CWD. The CWD-IFMP recommends several capital improvement projects for the potable system including: ■ Construct New Reservoir in Pressure Zone 1 ■ Construct New Potable Reservoir at Reservoir Site 4C ■ Reservoir Seismic Retrofit and Site Rehabilitation ■ Construct Round Mountain Water Treatment Plant(RMWTP) ■ Rehabilitate or Construct Secondary Well at RMWTP ■ Construct Second Tierra Rejada Well and Blending Station ■ Expand Santa Rosa Line to 24-inch (Upland Road to San Rafael Way) ■ Complete 12-inch Main: Upland to Woodcreek Roads ■ New Pipeline east of Conejo Creek: Creek Crossing to Reservoir 1 B ■ Install Automated Meter Reading System ■ New Tierra Rejada Groundwater Management Plan (GWMP); Update Santa Rosa GWMP ■ Automated Hydroelectric Generator ■ Install Emergency Generator at Woodcreek Well In addition to the above project, CWD has identified several projects for further investigation that could improve local groundwater supplies and further reduce dependence on imported State Water Project (SWP) water. The feasibility of these projects depends on a number of variables that are in turn dependent on the course of action taken by both CWD and surrounding agencies, and the development of projects subsequent to those decisions. These projects include: ■ Regional Desalination Facility ■ Denitrification of Conejo Wellfield Groundwater ■ Desalinization of Santa Rosa Basin Groundwater ■ Dedicate all wells to Potable Distribution System ■ Pipeline Analysis and Replacement Program ■ Recharge Santa Rosa Basin with Non-Potable Surface Water ■ Recharge Perched Aquifer ■ Recharge Northeast Pleasant Valley Basin Forebay with Surface Water ■ Non-Potable Exchange Programs The existing non-potable water distribution systems are in the first phases of what will likely be a continual expansion over the planning period of the CWD-IFMP. The components of the non- potable water system included in the CWD-IFMP are: 432 Page 3 ■ Alternate Non-Potable Tank on Presilla Road Ridge ■ Upsize Creek Crossing Near Non-Potable 1A Tank ■ Tank Repair and Site Rehabilitation ■ Water Quality Improvement at Storage Ponds ■ Install Automated Meter Reading (AMR) System ■ Hydropneumatic Pump System at SR-9 Site CWD has at its disposal a large volume of non-potable water and several other potential sources of nonpotable water that could increase the total available to CWD. Of this total amount, CWD currently uses only a portion, and is investigating various ways by which to put that non-potable water to its best and most effective beneficial use. Several projects intended to convert non-potable water have been examined and include: ■ Convert Potable Reservoir 4C to Non-potable 4C Tank ■ Convert Potable Reservoir 3D to Non-potable Tank 3D ■ Construction of New Non-potable 3F Tank ■ Non-potable Distribution System Expansion in Pressure Zone 1 In addition to the above, several opportunities exist for future investigation of non-potable water including: ■ Non-potable Zone 1 ■ Properties Approaching Moorpark Road ■ Service to Lexington Hills and Vicinity ■ New Non-potable Tank at Potable Reservoir 4B Site ■ Further Improve Water Quality at Storage Ponds Potential Significant Environmental Effects of the Proposed Project: CEQA requires the Lead Agency to assess any environmental impacts from project implementation. The DPEIR focused on the following issue areas: aesthetics, agriculture, air quality (including climate change), biological resources, cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, land use and planning, mineral resources, noise, population and housing, public services, recreation, transportation/circulation, utilities and service systems, cumulative impacts and mandatory findings of significance. Public Review Period The public review period for the DPEIR will be from May 7, 2012 to July 6, 2012 at 4:30 p.m. (60 days). Please submit written comments to Camrosa Water District, 7385 Santa Rosa Road, Camarillo, California 93012, Attention: Joe Willingham. Comments may also be sent via E-Mail to: JoeW camrosa.com. For further information, please call (805) 482- 0643. Written comments received on the DPEIR prior to the close of the public review period on the environmental document will be considered in the Final EIR. Written comments received on the DPEIR will be addressed in a Response to Comments document, which together with the DPEIR will constitute the Final Program EIR. The Final Program EIR will be included in the consideration by CWD, as lead agency under CEQA, in deciding whether to approve the project. 433 Page 4 To ensure public access to the DPEIR, copies of the document will available for review at the City library listed below: City of Camarillo Public Library 4101 Las Posas Road Camarillo, CA 93010 Additionally, copies of the DPEIR are available for review at http://www.camrosa.com/public info pub.html and the Camrosa District office. 434 EXECUTIVE SUMMARY INTRODUCTION AND OVERVIEW The purpose of the Executive Summary is to provide a clear and simple description of the proposed project and its potential environmental impacts. Section 15123 of the California Environmental Quality Act (CEQA) Guidelinesi requires the executive summary to identify each significant effect with proposed mitigation measures and alternatives that would minimize or avoid that effect. The summary is also required to identify areas of controversy known to the Lead Agency, including issues raised by agencies and the public, and issues to be resolved including the choice among alternatives and whether or how to mitigate the significant effects. This Draft Program Environmental Impact Report (PEIR) has been prepared to evaluate specific environmental impacts associated with the proposed Camrosa Water District(CWD)Integrated Facilities Master Plan (IFMP), also referred to herein as the proposed project. CWD is the Lead Agency for the environmental review and,after the comment/response process,is the certifying agency for the Final EIR. On October 12,2011, CWD circulated a Notice of Preparation(NOP) (State Clearinghouse Number[SCH] 2011101027) of an EIR for review and comment by the public and responsible and reviewing agencies. The NOP review period extended for 30 days and ended on November 10,2011. The NOP, prepared by CWD, indicated that the proposed project may have significant effects on hydrology, water supply and water quality, geology and soils, mineral resources, agricultural resources, biological resources, cultural resources, traffic and circulation, air quality, noise, hazards and hazardous materials, aesthetics, and utilities/service systems. Due to these potential effects, an EIR is required to more fully evaluate potential adverse environmental impacts that may result from development of the proposed project. This Draft PEIR has been prepared in accordance with CEQA,2 as amended, and the State CEQA Guidelines for Implementation of CEQA.3 This Draft EIR also complies with the CWD's procedures for implementation of CEQA. The purpose of this Draft PEIR is to inform decision makers and the general public of any significant adverse environmental impacts that may be associated with the planning, construction, and operation of 1 California Environmental Quality Act,State CEQA Guidelines,Section 15123. 2 Public Resources Code Section 21000 et seq. 3 California Code of Regulations,Title 14,Section 15000 et seq. Impact Sciences,Inc. ES-1 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 CC ATTACHMENT 2 435 Executive Summary the proposed project, and to identify appropriate feasible mitigation measures and alternatives that may be adopted to reduce or eliminate these impacts. PROJECT LOCATION AND SETTING CWD is located in the southern portion of Ventura County, encompassing parts of the Cities of Camarillo, Simi Valley, Moorpark, Thousand Oaks, and unincorporated areas of Ventura County. Geographically, CWD is bounded by Calleguas Creek to the west, the Las Posas Hills to the north, the Simi Hills to the east and the Conejo Hills to the south. These features also help define the Tierra Rejada, Santa Rosa, and Pleasant Valleys. The smaller area southwest of the larger CWD footprint (the Campus Area) is comprised of several parcels, including California State University at Channel Islands campus (CSUCI), a number of social service agencies owned by the County of Ventura, agricultural acreage, and CWD's Water Reclamation Facility (WRF). CWD serves three classes of water (potable, non-potable recycled, and non-potable surface water)and provides wastewater services to various portions of its service area. The purpose of the proposed IFMP is to evaluate CWD's ability to meet its mission through the year 2035 and to plan for the capital requirements to accomplish that task. The evaluation contained in this plan was based on the latest population projections, land development trends, and water and wastewater demand forecasts available to CWD. The resulting recommendations are intended to serve as the roadmap for implementing the major capital improvements needed by CWD to serve both potable and non-potable water and sanitary service demands to the year 2035 and beyond. PROJECT CHARACTERISTICS The proposed IFMP addresses CWD's potable water, non-potable surface water, recycled water distribution systems, and the wastewater collection and treatment facilities needs for the next 20 years. The purpose of the proposed IFMP is to evaluate CWD's ability to meet its mission through the year 2035 and to plan now for the facilities to accomplish that task. The proposed IFMP addresses issues that affect the long-term quality, reliability, and affordability of CWD's potable and non-potable water, and wastewater services. The following is a list of some of the challenges addressed by the IFMP. • Growth in demand will require identification of new sources of water supply and require re-rating of CWD's water reclamation facility to deal with higher flows. • Decreasing reliability of imported water supplies will require new alternatives to meet existing and new demands. Impact Sciences,Inc. ES-2 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 436 Executive Summary • New local sources of water must be developed to insulate CWD's customers from future drought. • Increasing cost of imported water will affect the affordability of potable water supplies. • Increasing regulatory requirements relating to water quality will increase costs of both potable and non-potable water operations. • Local water supplies must be managed and protected to serve the long-term needs of competing interests. • Increasing levels of environmental regulation will increase the costs of providing wastewater service. • Aging water and sanitary service infrastructures will eventually require rehabilitation or replacement. • Economies in operations must be realized to keep rates affordable. The proposed IFMP meets the challenges posed by these issues and formulates a comprehensive plan that minimizes the impact of these issues on CWD. The recommendations contained in the proposed IFMP reduce the dependency upon State Water Project water imported through Calleguas.In the process, the proposed IFMP strives to maximize the delivery of non-potable water and promote development of new, local supplies of both potable and non-potable water. It anticipates new water quality standards for both water service and wastewater discharge and recognizes that wastewater recycling must be increased to avoid discharge into the environment. The proposed IFMP promotes regional cooperation in meeting challenges shared by both CWD and its neighbors, and seeks to optimize the regional benefit from capital construction. Finally, the proposed IFMP recognizes that CWD must prepare for future infrastructure replacement to guarantee equity in financing capital replacement needs. CWD's boundaries overlap with portions of four jurisdictions including the cities of Camarillo and Thousand Oaks, unincorporated areas of Ventura County, and CSUCI. Of the approximately 31 square miles encompassed by CWD's boundaries, about 7 square miles are within the City of Camarillo, 1.5 square miles are attached to the City of Thousand Oaks, and 22 square miles lie in unincorporated Ventura County. Each of these areas has a general plan with land use and zoning classifications. In addition, CSUCI has full land-use authority over its 750-acre campus at CWD's southwestern boundary. Parcels in CWD's service area comprise a broad mix of agricultural and urban uses, which complicates current water use pattern analysis and future demand projections. To facilitate demand analysis, parcels are grouped into planning divisions that are generally aligned with the land use and zoning classifications contained in the respective general plans that govern the areas. Each of CWD's six planning divisions(Mission Oaks, Camarillo Springs, Santa Rosa Valley,Tierra Rejada Valley, Campus, and Santa Rosa Greenbelt areas) have distinct land use patterns and unique water use Impact Sciences,Inc. ES-3 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 437 Executive Summary characteristics,making generalizations about each division's water consumption possible.Despite the fact that water consumption patterns are similar across parcels within each division, usage patterns are strikingly different when divisions are compared with one another. Future demands in the CWD service area for the planning period 2010 through 2035 were projected in CWD's 2010 Urban Water Management Plan, which provided the basis for calculating ultimate water demands to be supplied by CWD. Anticipated land use changes from current zoning were incorporated into the analysis. It must be noted that the demand projections depend on the long-term accuracy of the available planning documents. If the cities, County, or special districts significantly revise their land use maps or general plans, the population projections, and corresponding demands may also change significantly. It is expected that land designated on current land-use maps for commercial or residential use will be built out over the next 20 years. Parcels currently in agricultural production but zoned for municipal and industrial (M&I) use will likely be developed over the next 20 years, and the analysis contained in this section reflects that significant change in demand pattern. The proposed IFMP assumes that existing zoning designations and land uses will continue. Most of the new demand in CWD will occur south of Santa Rosa Road in Santa Rosa Valley,north of Upland Road in the Mission Oaks planning area, and South of Highway 101 near the existing industrial park in the Camarillo Springs planning area. Overall, CWD's potable water distribution is in good operating condition. In most areas, the system is able to meet the customer demands at the minimum criteria. The system has adequate imported water supply to meet existing demands, but could benefit from improvements to the local groundwater production infrastructure. With the various opportunities for system improvements in mind, a number of projects have been identified to improve the existing potable water facility infrastructure. Improving reliability and water quality are two guiding principles used to identify future projects. The proposed IFMP recommends several capital improvement projects for the potable system including: • Construct New Reservoir in Pressure Zone 1, • Construct New Potable Reservoir at reservoir Site 4C, • Reservoir Seismic Retrofit and Site Rehabilitation, • Construct Round Mountain Water Treatment Plant(RMWTP), • Rehabilitate or Construct Secondary Well at RMWTP, • Construct Second Tierra Rejada Well and Blending Station, • Expand Santa Rosa Line to 24-inch(Upland Road to San Rafael Way), Impact Sciences,Inc. ES-4 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 438 Executive Summary • Complete 12-inch Main:Upland to Woodcreek Roads, • New Pipeline east of Conejo Creek:Creek Crossing to Reservoir 1B, • Install Automated Meter Reading System, • New Tierra Rejada Groundwater Management Plan(GWMP);Update Santa Rosa GWMP, • Automated Hydroelectric Generator, and • Install Emergency Generator at Woodcreek Well. In addition to the above projects, CWD has identified several projects for further investigation that could improve local groundwater supplies and further reduce dependence on imported SWP water. The feasibility of these projects depends on a number of variables that are in turn dependent on the course of action taken by both CWD and surrounding agencies, and the development of projects subsequent to those decisions.These projects include: • Regional Desalination Facility • Denitrification of Conejo Wellfield Groundwater • Desalinization of Santa Rosa Basin Groundwater • Dedicate all non-potable wells to Potable Distribution System • Pipeline Analysis and Replacement Program • Recharge Santa Rosa Basin with Non-Potable Surface Water • Recharge Perched Aquifer • Recharge Northeast Pleasant Valley Basin Forebay with Surface Water • Non-Potable Exchange Programs The existing non-potable water distribution systems are in the first phases of what will likely be a continual expansion over the planning period of the proposed IFMP. The components of the non-potable water system included in the proposed IFMP are: • Alternate Non-Potable Tank on Presilla Road Ridge • Upsize Creek Crossing Near Non-Potable 1A Tank • Tank Repair and Site Rehabilitation • Water Quality Improvement at Storage Ponds Impact Sciences,Inc. ES-5 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 439 Executive Summary • Install Automated Meter Reading(AMR)System • Hydropneumatic Pump System at SR-9 Site CWD has at its disposal a large volume of non-potable water and several other potential sources of non-potable water that could increase the total available to CWD. Of this total amount, CWD currently uses only a portion, and is investigating various ways by which to put that non-potable water to its best and most effective beneficial use. Several projects intended to convert non-potable water have been examined and include,but shall not be limited to: • Convert Potable Reservoir 4C to Non-potable 4C Tank • Convert Potable Reservoir 3D to Non-potable Tank 3D • Construction of New Non-potable 3F Tank • Non-potable Distribution System Expansion in Pressure Zone 1 In addition to the above, there are several opportunities for future investigation of non-potable water including: • Non-potable Zone 1 • Properties Approaching Moorpark Road • Service to Lexington Hills and Vicinity • New Non-potable Tank at Potable Reservoir 4B Site • Further Improve Water Quality at Storage Ponds Demand by irrigators within CWD and demand for surplus non-potable water by irrigators outside CWD's boundaries will be driven by the increasing cost of potable water and will require that the CWD plan for augmentation of its existing non-potable supplies. Since every acre-foot of potable water displaced by non-potable use saves CWD and the customer a considerable sum,it is in the best interest of both to improve the quality of the non-potable supply and increase the acceptability of using non-potable water to meet irrigation needs. The CWD's Renewable Water Resource Management Program is an ambitious interagency project to reduce reliance on imported water supplies while improving water quality. The project will be implemented over the planning horizon for this plan.Certain elements of that broader plan are integrated into the proposed IFMP in all three service areas (potable water, non-potable water, and wastewater service).Some of the key elements of the broader plan related to non-potable water include: Impact Sciences,Inc. ES-6 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 440 Executive Summary • Interconnection of Hill Canyon Wastewater Treatment Plant to Non-potable Distribution System,and • Introduction of Camarillo Sanitation(CamSan)Recycled Water. The existing treatment process at the Camrosa WRF is a proven process, and has operated well since construction in 1997.However,a number of projects are recommended to improve the existing process or replace existing facilities. The following projects, as discussed in the proposed IFMP, would relocate the existing effluent discharge point contained in CWD's National Pollutant Discharge Elimination System (NPDES)permit, correct known collection system problems,and improve biosolids handling at the plant: • New Discharge Point below Potrero Road • Sewer Collection Line Repair at Three Locations(6200 block of Calle Bodega,northwest corner of the intersection of Mission Oaks Boulevard,and Adolfo Road and Oaks Canyon Road) • Sewer Pipeline Replacement along Calleguas Creek • Mechanical Bar Screen Replacement at WRF • Biosolids Handling Capability Improvements • Grit Handling • Camrosa WRF Effluent Line Replacement A capacity analysis completed by CWD indicates that the plant can be re-rated from 1.5 million gallons per day (MGD) to 2.25 MGD with the re-introduction of filter equalization and activation of polymer injection to meet peak flow periods and the expansion of the chlorination facility.Both reactivation of the filter equalization process and polymer injection process can be accomplished at minimal cost, but expansion of the chlorination facility is more costly and will require significant capital investment. The analysis also confirms that the plant could be further expanded to 2.8 MGD with the addition of a third clarifier for redundancy during peak flows and expanded reliance upon the filter equalization process and polymer injection process. Since the expansion of the chlorination facility will be sized to accommodate the peak allowable flow through the filters, no additional chlorination capacity would be required. A separate analysis indicates that within the current sewer service area, there will be little additional growth in sewer flows other than those generated as a result of the expansion of CSUCI to full buildout. Flows are expected to reach a maximum of 2.05 MGD into the year 2030. With that in mind, the only capacity expansion project proposed for the near future is the expansion of the chlorination facility to allow re-rating of the plant to 2.25 MGD. Impact Sciences,Inc. ES-7 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 441 Executive Summary If the sewer service area were to be expanded further, for example into the greenbelt to accommodate development of the Hartman Ranch area,additional aeration and clarification capacity may be needed. Future capacity expansion projects include: • Expand Chlorination Facility, • Additional Clarifier Capacity, • Expand Oxidation Capacity of Oxidation Ditches,and • Pipeline and Lift Station at Future Adolfo Road Bridge. SUMMARY OF PROPOSED PROJECT IMPACTS This PEIR is focused on the environmental impact categories identified by the CWD as having potentially significant impacts during the notice of preparation and public review period for the initial study. Environmental factors are listed by the level of significance of their impacts, both project-specific and cumulative in Table ES-1, Significance of Environmental Issues for the Proposed IFMP, as analyzed in the PEIR. Table ES-1 Significance of Environmental Issues for the Proposed IFMP sigmfiearff aan Significant tti Less i` gzufi None Aesthetics Agricultural Resources Air Quality Greenhouse Gases Biological Resources Land Use Cultural Resources Mineral Resources Geology and Soils Park and Recreation Hazards and Hazardous Materials Population and Housing Hydrology and Water Quality Public Services Noise Traffic and Transportation Utilities and Service Systems Energy MITIGATION MEASURES A summary of the impacts, mitigation measures, and residual impacts for the proposed IFMP and alternatives is provided in Table ES-2,Summary of Project Impacts,Mitigation Measures,and Residual Impacts. Impact Sciences,Inc. ES-8 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 442 Executive Summary ALTERNATIVES TO THE PROJECT An EIR must briefly describe the rationale for selection and rejection of alternatives.The lead agency may make an initial determination as to which alternatives are feasible, and therefore merit in-depth consideration,and which are infeasible. Alternatives considered include a range of potential projects to meet CWD's objectives while eliminating or reducing significant environmental impacts identified. The following alternatives to the proposed project are considered: Alternative 1: No Project Alternative-no adoption of a master plan The State CEQA Guidelines require the analysis of a No Project Altemative.4 This analysis must discuss existing conditions, as well as what would be reasonably expected to occur in the foreseeable future if the project were not to be approved based on current plans, site zoning,and consistency with available infrastructure and community services. Under the No Project Alternative, the proposed IFMP would not be adopted and the various projects listed therein would not be constructed. Alternative 2: Reduced Scope Master Plan - Existing Facility and Infrastructure Replacement and Upgrades Only Under this alternative,no new facilities or expansions would be completed.The Reduced Scope Master Plan would be limited to the replacement and upgrades of existing facilities and equipment. Components of the Reduced Scope Master Plan would include: Potable system: • Reservoir Seismic Retrofit and Site Rehabilitation • Install Automated Meter Reading System • Automated Hydroelectric Generator • Install Emergency Generator at Woodcreek Well • Pipeline Analysis and Replacement Program 4 California Code of Regulations, Title 14, Division 6, Chapter 3, California Environmental Quality Act Guidelines, Section 15126.6(e). Impact Sciences,Inc. ES-9 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 443 Executive Summary Non-potable water system: • Tank Repair and Site Rehabilitation • Water Quality Improvement at Storage Ponds • Install Automated Meter Reading(AMR)System • Hydropneumatic Pump System at SR-9 Site • Introduction of Camarillo Sanitation(CamSan)Recycled Water Wastewater system: • Sewer Collection Line Repair at Three Locations (6200 block of Calle Bodega, northwest corner of the intersection of Mission Oaks Blvd., and Adolfo Road and Oaks Canyon Road) • Sewer Pipeline Replacement along Calleguas Creek • Mechanical Bar Screen Replacement at WRF • Biosolids Handling Capability Improvements • Grit Handling • CWRF Effluent Line Replacement The descriptions and components of these projects are the same as for the proposed project and described in Section 2.4.2,Summary of Proposed Integrated Facilities Master Plan,of the Project Description. These alternatives were identified to avoid or minimize the significant impacts identified for the proposed project. Table ES-3, Comparison of Alternatives to the Proposed IFMP, provides a comparative analysis of the environmental impacts of the proposed LIMP and the alternatives identified listed above. No alternatives were identified that meet most of the project objectives and avoid or substantially minimize the significant impacts identified for the proposed project. The State CEQA Guidelines require that an environmentally superior alternative be identified among the selected alternatives(excluding the No Project alternative).5 If the No Project Alternative is determined to 5 California Public Resources Code,Title 14,Division 6,Chapter 3, California Environmental Quality Act Guidelines, Section 15126.6(e)(2). Impact Sciences,Inc. ES-10 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 444 Executive Summary be the environmentally superior alternative, an environmentally superior alternative must also be identified among the remaining alternatives. The No Project Alternative (Alternative) would have the fewest impacts and would not result in any new significant impacts. Additionally, the No Project Alternative would result in greater impacts to surface hydrology and water quality, groundwater quality, and utility and service systems. Impacts related to land use and planning would be similar to those of the proposed project. However,the No Project Alternative would not meet the objectives of the proposed project. The Reduced Scope Master Plan Alternative also would result in less or similar impacts for most issues as the proposed project within the CWD service area. However, as with the No Project Alternative, impacts to groundwater and water quality would most likely be greater than the proposed project as there would be no expansion of existing facilities or new potable water and non-potable water facilities or plans to minimize potential groundwater impacts. Impacts to the groundwater levels and groundwater quality within the Santa Rosa and Pleasant Valley Groundwater Basins would be greater than the proposed project. By developing the Reduced Scope Master Plan as opposed to the proposed project, CWD would not achieve the following objectives to the same extent as the proposed project: • Ensure future reliable potable and non-potable water supplies to meet the future projected water demand within the District. • Reduce the dependency upon State Water Project water imported through Calleguas Municipal Water District. • Optimize the regional benefit from capital construction. • Prepare for future infrastructure replacement to improve reliability and guarantee equity in financing the capital replacement needs of the CWD. • Reduce salt loading on the watershed. Therefore, neither the No Project nor the Reduced Scope Master Plan are fully environmentally superior to the proposed project in that they do not provide for the CWD to reduce impacts that could occur to local groundwater resources. However, the Reduced Scope Master Plan provides for basic ongoing maintenance and replacement of aging infrastructure and would avoid potential impacts associated with potential failure of existing CWD potable,non-potable,and wastewater system components.Therefore, of the two alternatives analyzed, it would be environmentally superior. However, the Reduced Scope Impact Sciences,Inc. ES-11 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 April 2012 445 Executive Summary Master Plan would not allow the CWD to address the need to provide more reliable system options or decrease the use of imported water. Therefore,it does not allow the CWD to meet its objectives. AREAS OF KNOWN CONTROVERSY The State CEQA Guidelines require a Draft EIR to identify areas of controversy known to the Lead Agency, including issues raised by other agencies and the public. Comments were received from public agencies and interested parties in response to the circulated NOP and at the public scoping meeting.

If construction activities on the native wildlife nursery sites? site are proposed during the nesting/breeding season (February 1 through August 31), a pre-construction activity survey shall be conducted by a qualified biologist to determine if active nests of species protected by the Migratory Bird Treaty Act(MBTA)or the California Fish and Game Code are present in the construction zone. Once the survey is complete, a report shall be prepared and sent to the CDFG and Camrosa Water District for review and concurrence. If active nests are observed and located, consultation with the CDFG to establish appropriate buffers will be required and the results of the report shall be submitted to CDFG for review and approval. CWD shall ensure that proper CDFG approved buffers are in place prior to grading initiation. No grading shall occur before the appropriate buffers have been marked within the construction area. In addition, a biological monitor will also be required to be on site during all grading activities to ensure that the buffers are not compromised. At the conclusion of all grading activity, the biological monitor will submit a letter report to the CWD and CDFG summarizing the result of the grading activity. Where nesting birds are found, protection of nests shall include postponing or halting clearing and construction activities within 500 feet of the nest until the nest is vacated and juveniles have fledged and there is no evidence of a second attempt at nesting,as determined by the biologist. Construction personnel shall be instructed on the sensitivity of nest areas and shall be instructed to avoid entering the approved buffers around the nest.The biologist shall serve as a construction monitor during those periods when construction activities will occur near active nest areas(within 500 feet)to ensure that no inadvertent impacts on these nests will occur. The results of the survey,as well as any avoidance measures taken and the success of those measures,shall be submitted to the CWD and CDFG within 30 days of completion of the pre-construction surveys and/or construction nest monitoring to document compliance with applicable state and federal laws pertaining to the protection of native birds. Impact Sciences,Inc. ES-21 Camrosa Water District Integrated Facilities Master Plan Program EIR CCn 1127.001 April 2012 U1 Executive Summary Biological Resources(continued) 5.4-4 No earlier than 30 days prior to the commencement of construction activities, a pre-construction survey should be conducted by a qualified biologist to determine if active roosts of special-status bats are present on or within 300 feet of the project disturbance boundaries. Should an active maternity roost be identified (in California, the breeding season of native bat species is generally from April 1 through August 31),the roost should not be disturbed and construction within 300 feet should be postponed or halted, until the roost is vacated and juveniles have fledged. Surveys should include rocky outcrops, caves, structures, and large trees (particularly trees 12 inches in diameter or greater at 4.5 feet above grade with loose bark or other cavities). Trees and rocky outcrops should be surveyed by a qualified bat biologist (i.e., a biologist holding a CDFG collection permit and a Memorandum of Understanding with CDFG allowing the biologist to handle bats).If active maternity roosts or overwintering sites are found, the rock outcrop or tree occupied by the roost should be avoided (i.e., not removed)by the project. If avoidance of the maternity roost must occur, the bat biologist should survey (through the use of radio telemetry or other CDFG approved methods)for nearby alternative maternity colony sites. If the bat biologist determines in consultation with and with the approval of CDFG that there are alternative roost sites used by the maternity colony and young are not present then no further action is required. If a maternity roost will be impacted by the project, and no alternative maternity roosts are in use near the site, substitute roosting habitat for the maternity colony should be provided on,or in close proximity to,the project site no less than three months prior to the eviction of the colony.Large concrete walls(e.g.,on bridges) on south or southwestern slopes that are retrofitted with slots and cavities are an example of structures that may provide alternative potential roosting habitat appropriate for maternity colonies. Alternative roost sites must be of comparable size and proximal in location to the impacted colony. CDFG should also be notified of any overwintering sites or active nurseries within the construction zone. Impact Sciences,Inc. ES-22 Camrosa Water District Integrated Facilities Master Plan Program EIR 1127.001 Ul April 2012 01 Executive Summary Biological Resources(continued) Mitigation Measure 5.4-4(continued) If non-breeding bat overwintering sites are found in trees scheduled to be removed or in crevices in rock outcrops within the grading footprint, the individuals should be safely evicted, under the direction of a qualified bat biologist,by opening the roosting area to allow airflow through the cavity or other means determined appropriate by the bat biologist(e.g.,installation of one-way doors). In situations requiring one-way doors, a minimum of one week should pass after doors are installed and temperatures should be sufficiently warm for bats to exit the roost because bats do not typically leave their roost daily during winter months in southern coastal California.This action should allow all bats to leave during the course of one week. Roosts that need to be removed in situations where the use of one-way doors is not necessary in the judgment of the qualified bat biologist in consultation with CDFG should first be disturbed by various means at the direction of the bat biologist at dusk to allow bats to escape during the darker hours,and the roost tree should be removed or the grading should occur the next day (i.e., there should be no less or more than one night between initial disturbance and the grading or tree removal). These actions should allow bats to leave during nighttime hours, thus increasing their chance of finding new roosts with a minimum of potential predation during daylight. If an active maternity roost is located on the project site, and alternative roosting habitat is available,the demolition of the roost site must commence before maternity colonies form (i.e., prior to March 1) or after young are flying (i.e., after July 31) using the exclusion techniques described above.

ES-30 Camrosa Water District Integrated Facilities Master Plan Program EIR J, 1127.001 April 2012 Executive Summary Hydrology and Water Quality(continued) Perched Aquifer 5.9-4 Prior to the construction of any secondary well(s)or rehabilitation of an existing well(s) within the Perched Aquifer to increase existing withdrawal rates, the CWD shall complete an analysis to determine impacts associated with increased withdrawals including but not limited to the extent of the well's cone of depression and the rate of return from the operation of an additional well within the Perched Aquifer on nearby wells.Should the study identify impacts to other nearby wells or that the increased or additional rate of withdrawal from the Perched Aquifer will result in the lowering of the water table, mitigation measures shall be identified and implemented. If such measures cannot reduce impacts to an acceptable level of withdrawal, no additional wells shall be installed and the current historic pumping rate for existing wells shall not be increased. This analysis shall be completed by a licensed hydrogeologist.

The Camrosa Water District and the contractor shall designate a noise disturbance point of contact that would be responsible for responding to complaints regarding construction noise. The point of contact shall determine the cause of the complaint and ensure that reasonable measures are implemented to correct the problem. A contact number for the noise disturbance shall be conspicuously placed on construction site fences and written into the construction notification schedule sent to nearby residences. 5.11-2 Wells, pumps, and booster stations located within 150 feet of sensitive receptors(i.e.,residences,schools,or hospitals)shall have a noise study conducted to verify that the design will meet the cities of Camarillo and Thousand Oaks or Ventura County noise standards.
