B. Scope The scope of the proposed new grading policies and standards includes the following: Prior Language Added Subject Revised Language 1. Conceptual grading plans X 2. Import / Export X 3. Stockpiles X 4. Haul Routes X 5. Erosion Control X 6. NPDES Requirements X 7. Dust Control X 8. Review by Community Development X 9. Engineering Review X 10. Final Plans X 11. Field Changes X Grading policy2 0000so Revisions to Grading Policy December 15, 1999 Page 2 C. Changes Attached as Exhibit 1 is a copy of the proposed new grading policies written in legislative format showing the proposed changes. D.

The following guidelines shall be followed by the City Engineering Department in the review and approval of certain subdivision maps grading plans and the administration of grading operations : 1 . Conceptual Grading Plans : On all tentative tract maps, parcel maps , LDMs and DPs and applications for land development where grading quantities will be equal to or greater than fifty cubic yards (50 yd3) , obstruct a drainage course or impact another property owner ' s property, a conceptual grading plan shall be a part of the tentative tract map submittal to the City. The conceptual grading plan shall show pad elevations, tops and toes of slopes and walls, borrow and fill quantities, and the general drainage pattern. The location of any anticipated siltation, retention or debris basins shall be shown. If it is anticipated that the cut and fill volumes will not balance, the borrow site(s) and fill sitc (s) shall bc identified. If the borrow/fill site (s) arc within thc City limits, a grading plan for such site-, showing thc before and after condition, shall also bc 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 yd3) 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 . Import/Export : On all required conceptual grading plans where the total on-site borrow and fill yardages differ by one thousand cubic yards (1000 cu yd) 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 hundred (100) total truck loads or one thousand cubic yards (1, 000 yd3) , whichever is less, shall require Council approval prior to the commencement of Exhibit 1 Draft Grading Policy Page2 of 4 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. 3 . Stockpiles: Temporary stockpiling of soil in excess of one thousand (1000) cubic yards shall require approval by the City Council .
