(3) Slope StabilQFactors of Safety. When required fin is Title to provide site- <br /> specific geologic and engineering slope stability analysis, the following minimum <br /> slope stability factors of safety shall apply: <br /> li <br /> (a) A minimum factor of safety of 1.5 against static deep-seated failure. <br /> (b) A minimum factor of safety of 1.5 against static surficial failure. <br /> (c) A minimum factor of safety of 1.1 against seismic failure; <br /> (4) Tem ora Cut Slopes at Setback Lines. Temporary cut slopes (i.e., for limited <br /> periods of time, slopes that are in the process of extraction prior to being <br /> backfilled) at setback lines shall not exceed one (1) foot horizontal to one (1) <br /> foot vertical, except that temporary cut slopes at setback lines to a maximum of <br /> one half (112) of a foot horizontal to one (1) foot vertical may be maintained if <br /> site-specific geologic and engineering analysis demonstrate through a slope <br /> stability analysis that the proposed temporary cut slopes will have a minimum <br /> slope stability factor of safety as required in Section 9-1415.3(k)(4). However, <br /> in the event that there are existing structures on the adjacent property (or the <br /> immediate potential for structures on the adjacent property), the excavation <br /> shall at not time be closer to the property line than a line projected on a slope of <br /> one (1)to one (1)from the property fine to the toe of slope. <br /> (5) Final Slopes. Final cut and/or fill slopes shall not exceed two (2) feet horizontal <br /> to one (1)foot vertical, except as specified below: <br /> (a) Final slopes to a maximum of one and one-half(1 112) feet horizontal to one <br /> (1) foot: vertical may be maintained when site-specific geologic. and <br /> engineering analysis demonstrate through a slope stability analysis that the <br /> proposed final slopes will have a minimum slope stability factor of safety as <br /> required in Section 9-1415.2(k)(4), while demonstrating suitability for the <br /> proposed end use and protecting against erosion (by means of revegetation <br /> or other methods approved by Development Services Division). <br /> (6) Fill Slopes. Fill slopes shall be constructed consistent with recommendations <br /> from a qualified civil/geotechnical engineer based upon site-specific geologic <br /> conditions; <br /> I. FENCING: Six-foot-high security fencing or an approved equivalent shall be <br /> required where slopes steeper than two feet horizontal to one-foot vertical are <br /> created. (Development Title Section 9-1415.3[1]) <br /> m. SCREENING AND LANDSCAPING: Screening consistent with Chapter 9-1020 is <br /> required. (Development Title Section 9-1415.3[m]) <br /> q <br /> (1) A landscaped berm is required. Adequate setback for maintenance shall be <br /> required and sight distance at road intersections shall not be impaired. <br /> 1, <br /> n. PONDING: All water utilized in the plant operation shall be disposed of behind a <br /> closed dike. (Development Title Section 9-1415.3[n]) <br /> o. EXCAVATION/RECLAMATION SCHEDULE: The reclamation plan shall show the <br /> phases of excavation. Reclamation on one phase of an excavation shall be <br />
