Topsoil would be distributed, watered, and graded to an approximately 6-to 9-inch thickness.After <br /> placement and grading are complete, the material would be track rolled (a method for the compaction of <br /> soil on a slope to increase slope stability and establishment of vegetation)to prevent erosion and <br /> enhance seeding. The total volume of the topsoil would be 797,390 cubic yards. The final thickness would <br /> be less than the original thickness due to shrinkage, loss in handling, and intermixing. The total volume of <br /> overburden (other than topsoil)would be 6,644,917 cubic yards. It is estimated that the interbedded clays <br /> would be 14,730,000 cubic yards. The overburden and clays together total 21,374,917 cubic yards. <br /> Approximately 7.2 million cubic yards of material (including shrinkage factor)would be needed to build out <br /> the slopes from 314:1 to 2:1. <br /> Revegetation <br /> Upon final grading, all disturbed areas will be revegetated. Topsoil from the stockpiles would be placed on <br /> all final reclaimed 2:1 slopes and would be revegetated with a non-irrigated hydroseed mix consisting of <br /> 80 percent Zorro fescue and 20 percent rose clover. Pit bottoms would be graded smoothly and uniformly <br /> flat and revegetated with an agricultural crop. <br /> End Uses <br /> All reclaimed areas except for the slopes will be returned to land that can be used for agriculture. <br /> Reclamation will be complete when the productive capability of the land is equivalent to or exceeds, for <br /> two consecutive crop years, that of the premining conditions or similar crop production in the area. The <br /> slopes will be open space. <br /> Recommendation <br /> Approval of Project and Certification of FEIR. <br /> San Joaquin County QX-01-2\Lonestar California <br /> Community Development Page 13 <br />
