J (6) Final slopes shall not exceed two feet horizontal to one foot vertical. Exception: Final slopes to a maximum of one and one-half feet horizontal to one foot vertical between terraces may be maintained when site-specific geologic and engineering analysis demonstrate through a slope stability analysis that the proposed final slopes will have,a minimum slope stability factor of safety as required above, while demonstrating suitability for the proposed end use and protecting against erosion(by means of revegetation or other methods approved by Development Services Division). Exception: Final fill slopes to a maximum of 1.1.feet horizontal to 1 foot vertical between 30-foot-wide terraces may be maintained on the north and west sides of Phase 2 adjacent to the southem and eastem sides of the plant (Phase 1). These compacted fill .slopes shall be overbuilt and then cut back to the final profile. Stockpiled material may be placed at the top of these slopes for purposes of surcharge. (7) All fill slopes shall be compacted to an average of 85 percent (with a minimum of 82 percent) of maximum density. Fill shall be placed in maximum three-foot- high I"ifts. During construction of fill slopes, fill material shall be keyed into the temporary cut slope so that it will not be placed on top of the sloped portion of temporary cuts. The method to create a fill slope shall be given an initial test by a geotechnical engineer to establish the percent of compaction. Submit additional random tests as required by Development Services Division. The geotechnical engineer for the above inspections shall be selected by San Joaquin County with the applicant being responsible for the cost of the professionalized services plus an administrative fee of 15 percent. (8) Establish survey monuments at each of the following locations and submit annual readings performed by a licensed land surveyor that will detect possible horizontal and/or vertical creep: (A) Phase 2: adjacent to both the east and south boundaries of Phase 1. (B) Phase 2: adjacent to the Califomia Aqueduct and Blewett Road. (C) Phase 3: adjacent to the Califomia Aqueduct, Bird Road, Lone Tree Creek, and the PG&E pipeline. (D) Phase 4: adjacent to the Califomia Aqueduct, Blewett Road, and Lone Tree Creek. i (E) Phase 5: adjacent to State Highway 132, Bird Road, the Califamia Aqueduct, and Lorre Tree Creek. I (F) Phase 6: adjacent to Interstate 5, Blewed Road, and the Califomia Aqueduct. l (G) Phase 7: adjacent to Caldomia Aqueduct i i Conditions of Approval -4 - QX-91-5
