Geology Soils. and Seismicity County standards provide for temporary slopes as steep as 1:1 (H:V). Temporary slopes as steep as 1/2:1 may be permitted if site specific geologic and engineering analysis demonstrate 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)of the Development Title. The project proposes temporary slopes of%:1. A slope stability analysis determined that the proposal would meet the required safety factors. The applicant is also proposed final slopes of 2:1 with no terracing. Although the EIR found that this would not be a significant impact, terracing will be required every fifty(50)feet of height pursuant to Development Title Section 9-1415.3(k). The applicants indicated this would not be a problem. This impact is less than significant. Biological Resources "Waters of the U.S" (Wetlands). The EIR reviewed two mining options. Mining option 1 would leave Hospital Creek in place, mining both sides with a 100-foot setback from the centerline of the creek to the top of the mining slope(see figure 3-3, mining option 1). The second option would mine the creek. This project is for mining option 1. The EIR found that mining option one would not have a significant impact on"waters of the U.S". Special Status Species. The EIR determined that this project could have a significant impact on several special status species covered under the SJMSCP, including San Joaquin kit fox, tricolored blackbird, western burrowing owl, Swainson's hawk, white-tailed kite, and loggerhead shrike. The EIR determined that these impacts would be reduced to less than significant by complying with the SJMSCP for phases covered by the SJMSCP, For phases not covered by the SJMSCP(i.e., those in Stanislaus County), the EIR developed several mitigation measures that would reduce the impact to less than significant(see MMRP page 5-8, mitigation measures 4.9.2a-d). Biological Resource impacts are less than significant after mitigation. Cultural Resources The EIR found potentially significant impacts relative to damage to previously unidentified buried archaeological remains and human remains during project construction. The EIR found that these impacts to Cultural Resources would be reduced to less than significant with mitigation measures 4.10.1 and 4.10.2 (see MMRP page 5-12). Hazards The EIR determined that the project could have significant impacts relating to a possible existing underground storage tank, existing miscellaneous hazardous substances(e.g., gasoline, diesel fuel, solvents, etc.), above ground fuel tanks, and disease vectoring mosquitoes from the silt ponds. The EIR determined that these potentially significant impacts would be reduced to less than significant with mitigation measures 4.11.1, 2, and 4 (see MMRP page 5-13) Visual The project has the potential to conflict with the State of California Department of Transportation Scenic Highway Program and the County General Plan (specifically Resource Policy 13: Development proposal along scenic routes shall not detract from the visual and recreational experience). The EIR determined that mitigation measure 4.12.2 would reduce this impact to less than significant(see MMRP, page 5-13) San Joaquin County QX-01-2\Lonestar California Community Development Page 18
