San Joaquin County Community Environmental Setting,Impacts,and Mitigation Measures _ Development Department Aesthetics along the perimeters of the excavated areas. No revegetation would be conducted because the majority of the site would be returned to active agricultural cultivation(e.g.vine,row,or tree crops). _ Reclaimed areas will be returned to a fertility level similar to the existing crops grown on the property and fertilizers or other soil amendments used in _ reclamation,if any,will not cause contamination of groundwater. Success of reclaimed agricultural operations will be evaluated by a qualified agricultural consultant,and will be considered to meet acceptable fertility level when 80%of trees have success of establishment. If altemating row crops are planted, then success will be met when such row crops produce at least 80%product,as compared to surrounding properties on a per-acre basis. Side slopes are to be reclaimed. — The South Pit would be backfilled to its pre-mining elevation, and the North Pit would be backfilled to groundwater level and used as agricultural pond. — However,if less mining occurs than planned, more fines than expected are generated during mining,or a substantial amount of fill is brought to the site as backhaul from job sites, no pond would be left. Instead,the South Pit would be — backfilled to existing topography and the North Pit would be backfilled to a uniform grade 15 feet above groundwater(90 feet AMSL). The proposed end use for the project area involves returning the site to active agricultural uses and also includes developing an agricultural water basin. Implementation of the proposed reclamation plan would result in a land use consistent with the existing uses of the site and would be consistent with the aesthetics-related policies in the County General Plan (2010). Because the mined areas would be reclaimed to agricultural use, reclamation of the site would not result in a aesthetically offensive site. This impact is therefore considered less _ than significant. No mitigation is required. Impact AES-4: Produce New Sources of Light or Glare (Less than Significant with Mitigation Incorporated) The proposed Project would create a new source of substantial light or glare that would adversely affect daytime or nighttime views in the area. This impact is considered significant. As described in Chapter 2, "Project Description,"mine operations would take place from 6 a.m. to 8 p.m. for the quarry and aggregate plant, and 5 a.m. to 5 _ p.m. for the asphalt and Portland cement concrete plants. New sources of light and glare would be introduced with the establishment of mining activities and processing areas in the project site. This would increase the amount of ambient _ light that existing residents receive because the project site is presently undeveloped. Light spill from truck headlights entering and exiting the site would increase with mining operations. Appropriate lighting, a berm, and _ vegetative barriers would greatly reduce the amount of light affecting residents. DeSilva Gates Quarry Project Draft Environmental Impact Report 3,A-12 J&S 0510505
