C. GRADING: The following guidelines shall be followed by the City Engineering Department in the review and approval of grading plans and the administration of grading operations: 1. Conceptual Grading Plans: On all tentative tract maps, parcel maps, and applications for land development where grading quantities will be equal to or greater than fifty cubic yards (50 cu. yds.), obstruct a drainage course or impact another property owner's property, a conceptual grading plan shall be a part of the submittal to the City.

The location of any anticipated siltation, retention or debris basins shall be shown. As a condition of approval, surety shall be provided for the full cost of the grading operations. On projects where the grading quantities do not exceed twenty thousand cubic yards (20,000 cu. yds.) and where all grading is in an isolated self contained area (such as agricultural land) and where the actual limits of proposed grading will have a significant buffer from and have no drainage impact to adjacent properties, and the grading creates no adverse aesthetic impacts to views or hillsides, the City Engineer in consultation with the Director of Community Development after review of a plot plan and supporting information concerning drainage and buffer areas, may determine that a grading plan is unnecessary. 2. Contour Grading: a. Findings: The Council hereby finds that the terrain of certain areas of the City provides a unique and substantial character to the area and forms an integral part of the City's total environment. Due to their physical dominance on the City's landscape, development of the hillside areas will definitely affect the visual and environmental character of the community. The City's primary objective regarding hillside development is to preserve the natural terrain and aesthetic character of the City while encouraging creative, innovative, and safe residential development with a variety of housing types. Such characteristics will only be achieved when special consideration is given to those developments, subdivisions, and lot splits within hillside 000033 Resolution No. 2000 - Exhibit 'A' [Page 3] September 20, 2000 areas on an individual basis and proper consideration of the variations in conditions, design criteria, and other. b. Slope Design Standards: Where the creation of cut and fill slopes is approved, they shall be rounded at the edges and contoured as necessary to blend with existing topography. All cut and fill slopes shall conform to the following standards: 1) All cut and fill slopes in excess of five feet (5') vertical height shall be rounded with vertical curves from the crest of the slope and from any surface drains constructed on the face or top of the slope and must keep concentrated water from roofs, drives or pads from going over slopes or onto adjacent properties; 2) Where cut or fill slopes intersect the ends of each graded slope, the slope shall be horizontally rounded and blended with a minimum radius of twenty -five feet (25'). A smaller radius may be permissible for short slope lengths; 3) Where a cut or fill slope intersects a natural slope, the horizontal contours of the slope shall be curved so as to blend with the natural slope; 4) Where any cut or fill slope exceeds seventy feet (27') in horizontal length, the horizontal contours of the slope shall be curved in a continuous undulating fashion with radii no greater than three hundred feet (300') nor less than twenty feet (20'); 5) Slope rounding shall be designed in proportion to the total height of the slope. The top and toe of each slope in excess of ten feet (10') height, excepting the toe of any slope within twenty -five feet (25') of a dwelling, shall be vertically rounded with radii equal to one -fifth of the height of the slope and no less than five feet (6). This shall not apply to the toe of any cut slope that is supported by a retaining wall; 6) All engineered slopes shall be contour graded to achieve a natural appearance. Borders of cut slopes and fills are to be rounded to blend with the existing terrain; 7) Road and utility construction will not be approved until improvement plans have been approved for the area in accordance with discretionary approvals and City standards; and 8) Slope height shall be measured to the intersection of the slant of the slope with existing ground before rounding. c. Architectural Treatment: Architectural innovation shall be utilized rather than extensive grading so that the natural landform is disturbed to the least extent possible. 000034 Resolution No. 2000 - Exhibit 'A' [Page 41 September 20, 2000 d. Development Area Interfaces: Where approved by the Planning Commission or City Council, the slope grading requirements may be applied to limited portions of an adjacent zone to permit the extension or transition of a logical design concept. These requirements do not preclude satisfying requirements for slope benching, drainage facilities, and maintenance access or fire apparatus access roads. e. Development Guidelines for Natural Slopes: Areas within the following ranges of natural (pre - development) slope percentages shall be developed in accordance with the following criteria: 1) The "Percent Natural Slope" on a site will be calculated as the average gradient of the entire site as determined by the elevation differentials measured orthographically between each node of a north -south and east -west one hundred foot interval grid extending over the entire developed portion of the project site. 2) Areas having an average slope of less than ten percent (10 %) 110' horizontal to 1' vertical) are not a hillside condition. Mass grading with conventional fully padded lots and terracing are acceptable. 3) Areas having an average slope of between ten percent (10 %) [10' horizontal to 1' vertical] and nineteen and nine -tenth percent (19.9 %) 15' horizontal to 1' vertical]: Mass grading may occur in this slope zone. Existing landforms must retain their natural character. Padded building sites are permitted on these slopes, but split -level architectural structures with stacking and clustering are preferred. A cut and fill map is required to verify maximum heights of cut and fill. 4) Areas having an average slope of between twenty percent (20 %) [5' horizontal to 1' vertical] and thirty -three percent (33 %) [3' horizontal to 1' vertical]: Special hillside architectural and design techniques are required within this slope zone. Architectural designs are to conform to the natural landform. Mass grading is discouraged except on a case -by -case basis as permitted by the Planning Commission. Mass grading is particularly discouraged where development is proposed within a high -risk landslide area. This does not preclude grading necessary to mitigate slide hazards. A cut and fill map is required to verify maximum heights of cut and fill. 5) A Conditional Use permit is required for grading on areas having an average slope of thirty -four percent (34 %) or more [greater than 3' horizontal to 1' vertical). Approval of any Conditional Use permit for development within this slope zone is contingent that the Planning Commission make findings that such grading and development: a) Has been clearly demonstrated to minimize safety, environmental and aesthetic impacts. 000035 Resolution No. 2000 - Exhibit 'A' [Page 5] September 20, 2000 b) Includes the minimum amount of grading. c) Includes the grading necessary to mitigate slope instability or slide hazards that may exist on the site. d) Has had thorough geotechnical investigation. e) Has had a detailed grading plan prepared as well as a cut and fill exhibit that shows maximum heights of cut and fill. f) Will require no import or export of soils. 3. Import/Export: On all required conceptual grading plans where the total on -site borrow and fill yardages differ by one thousand cubic yards (1,000 cu. yds.) or more, plans for handling the import/export shall be part of the conceptual grading plan. a. The import/export plan shall show quantity of import/export, location of borrow /stockpile sites, temporary and final grading of the site, height of fill /depth of cut, visibility of the site from public roads and lands, vegetation and screening for sites located within the City of Moorpark. b. Unanticipated off -site import/export operations requiring an excess of one thousand (1,000) total truck loads or ten thousand cubic yards (10,000 cu. yds.), whichever is less, shall require Council approval prior to the commencement of hauling or staged grading operations. A haul route shall be submitted to the City Council for review and approval. c. If the borrow /fill site(s) are within the City limits, a grading plan for such sites, showing the before and after condition, shall also be shown. 4. Stockpiles: Temporary stockpiling of soil in excess of one thousand (1000) cubic yards shall require approval by the City Council. Lesser amounts may be administratively approved by both the Director of Community Development and City Engineer subject to the following: a. The height of the stockpile may not exceed five (5) feet b. Side slopes shall not exceed 3:1 c. Duration of the temporary stockpile shall not exceed six (6) months. d. Applicant shall submit a surety equal to the cost of export and disposal plus ten (10) percent. 5. Haul Routes: On all required conceptual grading plans that require import/export of more than one hundred (100) truckloads or one thousand cubic yards (1,000 cu. yds.), whichever is less, the following information shall be made a part of the conceptual grading plan: haul routes, hours of hauling, numbers and frequency of trucks and other information necessary to define hauling impacts. Additional surety for the cleaning and /or repair of streets used as haul routes may be required as determined by the City Engineer. Q90036 Resolution No. 2000 - Exhibit 'A' [Page 61 September 20, 2000 6. Director of Community Development Review: On all grading plans, the Director of Community Development shall provide comment to the City Engineer concerning: contour grading, aesthetics, viewshed and consistency with the Hillside Management Ordinance where applicable and Moorpark General Plan. With said comments, the City Engineer shall develop and provide to the Director of Community Development, appropriate recommendations relative to those matters plus slope stability, drainage, erosion protection and related issues, before approval of any conceptual or final grading plan. 7. Final Grading Plan: The final grading plan shall be in substantial compliance with the approved conceptual grading plan. The City Engineer and the Director of Community Development shall make the determination as to substantial compliance with the approved conceptual grading plan. The City Engineer may administratively approve minor changes from the conceptual grading plan. Minor changes are defined as: a. changes in elevation of three (3) feet or less from the conceptual plan; b. changes in total borrow /fill quantities which do not exceed one thousand cubic yards (1,000 yd3); c. additional import/export quantities not exceeding one thousand cubic yards (1,000 yd3); d. changes which cause no adverse impacts to slope stability, drainage, and erosion control; and, e. changes which, in the view of the Director of Community Development, do not result in any adverse impact on aesthetics or viewshed. If the City Engineer finds that the final grading plan is not in substantial conformance with the approved conceptual grading plan, the City Engineer shall submit a report with recommendations to the City Council. The City Engineer shall not issue a grading permit for those final grading plans that are not in substantial conformance with the conceptual grading plan without approval of the City Council. 8. Erosion Control: Concurrent with submittal of the final grading plan, an erosion control plan shall be submitted for review and approval by the City Engineer. The design shall include measures for erosion control to be implemented on all graded areas. These measures shall apply to temporary grading activity that remains or is anticipated to remain unfinished or undisturbed in its altered condition for a period of time greater than thirty (30) days or for a period of time which extends into the wet season defined as that period between October 15th of a given year and April 15th of the following year. 00003'7 Resolution No. 2000 - Exhibit 'A' [Page 7] September 20, 2000 9.
