Noise Several residences are located near the site and along studied haul routes(figure 4.5-2). The EIR determined that mining activities, plant operations and truck traffic will generate noise levels that exceed the County's noise standards.The EIR developed four feasible mitigation measures (see MMRP, page 5-4, Mitigation Measures 4.5.1.a-d). However, even with these measures, the EIR determined that it is likely that noise levels could still exceed County standard of 50 dBA Leq at the exterior property line of the three residences nearest to the project site (R3, R4, and R5). Noise impacts after mitigation remain significant. Land Use The EIR found that the project has the potential to conflict with existing and planned land uses surrounding the project site. However, application of the proposed mitigation measures will reduce that impact to less than significant. The EIR found that the project was consistent with applicable Land Use designations and policies. The EIR found that the project was consistent with the Surface Mining and Reclamation Act. The EIR found that the project would conform to the San Joaquin County Multi-Species habitat Conservation Plan by either participating in the plan or implementing equivalent mitigation measures described in Section 4.9, Biological Resources(See MMRP, page 5-8, Mitigation Measures 4.9.2ac). Land Use impacts are less than significant after mitigation. Traffic The EIR reviewed three haul routes. Haul route 2 proved unworkable, and haul route 3 was revised and is now"revised haul route 3." The applicant is proposing the use of haul route 1 on a permanent basis, and revised haul route 3 as a temporary option until the interchange at SR 132 and Bird Road is constructed. Haul route 1 and revised haul route 3 are shown in figure 4.4-2 and revised figures 4.4-3a and 4.4-3b. The EIR determined that traffic impacts could be reduced to less than significant with several mitigation measures(see MMRP page 5-3, mitigation measures 4.4.1a-e, 4.5.3). The Department of Public Works has determined that revised haul route 3 can be used after financing for the future State Route 132/Bird Road Interchange is completed. After the interchange is completed, haul route 1 shall be used. Agriculture The EIR found that the project would not conflict with the existing agricultural zoning of the subject properties nor with the provisions of an existing Williamson Act contract(See Williamson Act below). The EIR determined that the mining activities have the potential to result in offsite impacts to adjacent agricultural lands. However, implementation of Mitigation Measure 4.3.3 (dust control measures)would reduce that impact to less than significant. The EIR found that deep pit aggregate extraction will reduce the agricultural productivity of the project site. However, modification of the Reclamation Plan to incorporate elements of a comprehensive soil resource extraction, maintenance and reintroduction plan would reduce that impact to less than significant(see MMRP, page 5-2, Mitigation Measure 4.3.4). Agricultural impacts after mitigation are less than significant. Geology Soils, and Seismicity County standards provide for temporary slopes as steep as 1:1 (H:V). Temporary slopes as steep as ''/z: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 San Joaquin County QX-01-2\Lonestar California Community Development Page 17
