Silt Pond Construction While mining Phase I, the Phase IVB area would be bermed to create a temporary silt pond using Phase I and Phase IVB overburden. Once mining is completed in Phase I, it would be used for permanent silt containment and the silt temporarily contained in the Phase IVB area would be pumped into the Phase I silt pond. Once Phase IVB and Phase IVA are mined out, those pits will also become permanent silt ponds. If additional silt storage is needed during the course of mining, the Phase V area would be used as a silt pond. Figures 3-3 and 3-4 show the locations of the temporary silt ponds. Recycled water from the silt ponds and well water would be used for water supply. Once the silt ponds are established, decanted waters from the silt pond would be used in washing the sand and gravel, with approximately 25 percent well water being used for washing. Well water would be used in washing sand and gravel until the silt ponds are in operation. Landscaping and Screening Within a 50-foot setback along the northern portion of Koster Road and along Blewett Road, a landscape berm will be constructed out of overburden and topsoil removed from the initial mining phases. The berm along Koster Road will commence on the south side of Phase IX and extend northerly to Blewett Road with a break at the main entrance gate. The berm along Blewett Road will connect with the berm at the intersection with Koster Road and will extend easterly to the northeast corner of the Phase IVB area, and then extend approximately 700 feet along the easterly portion of the Phase IVB area. Existing trees will remain along a portion of the easterly side of the Phase IVB area. The applicant has completed a landscape plan that is available for review at the San Joaquin County Community Development Department, 1810 East Hazelton Drive, Stockton, California, and is incorporated herein by reference. The landscape berm will include a double row of trees and non-irrigated hydro seed mix that will serve to screen in part the plant facilities and act as a noise barrier. The trees that could be included along the landscape berm include: coolibah tree (Eucalyptus microtheca), afghan pine (Pinus eldarica), Indian longleaf pine (Pinus roxburghir), Lombardy poplar(Populus nigra italica), and English oak (Quercus robur fastigiata). The trees would be drip irrigated by an automatic and seasonally adjusted irrigation system providing 100 percent coverage in the area of the trees. The non-irrigated hydroseed mix would include 80 percent Zorro fescue and 20 percent rose clover. The hydroseed mix would be applied at 55 pounds per acre. Site Access A paved entrance to the plant site would be constructed off of Koster Road approximately 2,100 feet south of Blewett Road. The driveway will be paved at least 100 feet into the plant site. The on-site equipment and material haul roads would be unpaved. All employee and customer parking would be located at a designated parking zone, surfaced with asphalt and located on the site within the Phase IX area, the plant site. Secondary access will be off Blewett Road at the Phase IVB area. The applicant San Joaquin County QX-01-21Lonestar California Community Development Page 4
