j. SETBACKS: No excavation shall take place within 25 Feet of any property line or right- of--way (nor within the allowed slopes adjacent to said 25-foot setback) unless. the elevation prior to excavation is more than that of the abutting property, in which case the efevation within said 25-foot setback shall at no time be less than that of the abutting property, at the property line. (Development Title Section 9-1415.3G1) k. SLOPES: The following provisions do not apply to temporary interior cut slopes working slopes that do not fall within any of the criteria listed below). Temporary interior cut slopes shall comply with the Cal OSHA Code of Regulations andlor the Federal OSHA Code of Regulations, as applicable. (Development Title.Section 9-1415.3[kl) (1) T erracino Required All slopes over 50 feet in height shall. be terraced with a maximum vertical distance between terraces of 50 feet. Each terrace or beach shall be a minimum of 12 feet wide. (2) Terrace Drainage. Drainage plans with calculations shall be submitted for approval to the Development Services Division for.all teraces as part of the Reclarna#ion Plan. � r Terraces for reclaimed final slopes shall be sic �� ;� the fill and be aesioned such that runoff is airacted to c0lle:ion, noirrm w,erecan union:.aich basins and fie conveyed via pioes. or other acceptable conveyance tQ tyle toe of slope.

Th., method of transportingWater:he wat_r along the flow line of the terrace to the down drain, so as to prevent erosion and passible slope failure, shall he approved by the Development Services division. The method of drainage of terraces far temporary slopes at setback lines shall be submitted to the Development ServicA s i0avision for approval. (4) Slope 5taaility Factors o(_Safetv. When required in this Title to provide site- Specific geologic and engineering slope stability analysis, the fol€owing minimum slope stability Factors of safety shall apply: (A) A minimum factor of safety cf 1.5 against static deep seated failure, (B) 4 minimum facto r of saf..e ty of 1.5 against static surfiicial failure. (C) A ,minimum factor of safety of 1.1 against seismic failure. {c) T emoorary Cut Slopes at Setback Lines. Temporary cut slopes (i.e., for limited periods of time, siopes that are in the process of extraction prior to being backfilled) at setback lines shall not exceed one foot horizontal to one foot vertical, except that temporary cut slopes at setback lines to a maximum of one half of a foot horizontal to one foot vertical may be maintained if site-specific geologic and engineering analysis demonstrates through a Slope stability analysis that the proposed temporary cut slopes will have a minimum slope stability factor of safety as required in Section 9-1415.3(k)(4). However, in the event that there are existing structures on the ad)acent property (or the
