A. Final slopes to a maximum of one and one-half(1 1/2) feet horizontal to one (1) foot vertical 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 in Section 9-1415.2(k)(4), while demonstrating suitability for the proposed end use and protecting against erosion (by means of revegetation or other methods approved by Development Services Division). B. In accordance with mitigation measures required of this project, final slopes adjacent to the Stillmann Magee County Park shall not exceed 3 horizontal to 1 vertical. (5) Fill Slopes. Fill slopes shall be constructed consistent with recommendations from a qualified civil/geotechnical engineer based upon site-specific geologic conditions. I. FENCING: Fencing four(4)feet in height consisting of not less than three(3) strands of barbed wire, or an approved equivalent, shall be placed around the excavation area where slopes steeper than two (2) feet horizontal to one (1) foot vertical are maintained. Six (6) foot high security fencing or an approved equivalent shall be required where slopes steeper than two (2) feet horizontal to one (1) I vertical are created, if the proximity of such slopes to residential uses or other uses involving a concentration of people so warrants. (Development Title Section 9-1415.3[1]) (1) In accordance with mitigation measures required of this project, the quarry operator shall place a temporary chain-link fence along the boundary of the excavated slope adjacent to the Stillmann Magee County Park for the protection and safety of the general public should the park expand to increase public usage near the excavation area. m. SCREENING AND LANDSCAPING: Screening consistent with Chapter 9-1020 is required. (Development Title Section 9-1415.3[m]) n. EXCAVATION/RECLAMATION SCHEDULE: The reclamation plan shall show the phases of excavation. Reclamation on one phase of an excavation shall be initiated prior to the start of the next excavation phase. The final reclamation of any phase of excavation shall be completed within two years of the commencement of the reclamation process. Excavation shall be limited so that at any point of time a maximum of one phase is being reclaimed while one phase is being excavated. (Development Title Section 9-1415.3[o]) o. TIME LIMITATION: The Quarry Excavation Permit shall remain in effect as long as the excavation continues in compliance with the approved Permit. (Development Title Section 9-1415.3[p]) p. ANNUAL INSPECTION REPORTS: Annual inspections of the excavation shall be conducted by the County to ensure compliance with the conditions of the permit and the reclamation plan. The County may use professional services as provided for in Section 9-240.11. The consultant shall be selected by San Joaquin County. Upon completion of the annual inspection, the person in charge of the mining operation shall submit to the State Geologist and the County a report which shall contain all the information as required by Section 2207 of the Public Resources Code. The cost of the inspection shall be paid by the mine operator. Additional inspections may be conducted, but the cost of additional inspections shall be paid for by the mine operator only if non-compliance with the conditions of the Quarry Excavation Permit or the reclamation plan is found. (Development Title Section 9-1415.3[q]) q. PERFORMANCE GUARANTEE: In order to ensure reclamation of the site, compliance with conditions of approval, and compliance with County and state mining regulations, the applicant shall provide performance guarantees as a condition of the issuance of the Quarry Excavation Permit. The amount and form of the guarantee shall be subject to annual review and approval by the County and the state, and the amount shall be adequate to ensure reclamation of disturbed land and/or land to be disturbed during a given phase. The annual review of the financial guarantee shall be
