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 5A, 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 4.9.2a-c). Land Use impacts are less than significant after mitigation. Traffic The EIR reviewed three haul routes. Haul route 2 proved unworkable. The applicant is proposing the use of haul route 1 on a permanent basis, and haul route 3 as a temporary option until the interchange at SR 132 and Bird Road is constructed. Haul Routes 1 and 3 are shown in figures 4.2 and 4.3. The EIR determined that traffic impacts could be reduced to less than significant with several mitigation measures (see MMRP page 5-3, mitigation measures 4.4.1 a-e, 4.5.3). However, the Department of Public Works is recommending that haul route 3 be used only during the ground preparation phase of the project, and that no material is to be excavated until the interchange is completed. Construction of the interchange requires the cooperation of several excavators in the area. The Department of Public Works does not want any more excavation to be approved until the interchange is constructed. At his time, the financing for construction has not been completed. 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. Williamson Act Phases II and III (APNs 265-010-15 and 16)are under Williamson Act Contract. A Notice of Nonrenewal was approved for both parcels in October 2004. Those properties will be out of contract in 2015. Quarries are compatible uses under Williamson Act Contract provided that the land is rehabilitated for agricultural use, as is proposed (Section 9-1810.3[b][1][W]). This is a less than significant impact. San Joaquin County QX-01-2\Lonestar California Community Development Page 17
