Transit Mix Concrete Co. <br /> Topsoil Preservation <br /> Topsoil will be removed and segregated from other materials per Rule 3.1.9. The United States <br /> Department of Agriculture Natural Resources Conservation Service (NRCS) soil resources data <br /> were used to estimate the depth of salvageable topsoil that will be stockpiled for use in <br /> reclaiming affected areas of the project. Based on the NRCS data, a maximum of six inches of <br /> topsoil will be available for salvage from any new disturbance areas (Exhibit 1). Where <br /> practicable, removal of topsoil will occur when soils are dry to help preserve soil structure, <br /> reduce compaction and reduce the loss of pore space (Vogel, 1987). <br /> As outlined in Rule 3.1.9, where practicable, woody vegetation at the site will be removed from <br /> or appropriately incorporated in the existing topsoil prior to excavation. If this is not practicable, <br /> the woody vegetation will be chipped to incorporate into subsoils, or used as brush windrows for <br /> the project storm water management plan. <br /> The locations of proposed topsoil stockpiles can be found in the figures in Exhibit C. The <br /> locations and configurations of the topsoil stockpiles are designed to minimize erosion and <br /> disturbance. Topsoil removed from the access road corridor will be stockpiled in windrows <br /> adjacent to the access road. During Phases I through 11, topsoil removed will be stockpiled in <br /> one of the designated stockpiles. Beginning in Phase III and occurring through Phase V topsoil <br /> will be direct hauled and placed on reclaimed surfaces. Any remaining excess removed topsoil <br /> will be placed in TS4. The topsoil stockpile will be surrounded by a berm and runoff will be <br /> routed past the stockpile to prevent topsoil loss. In addition, depressions that entrap water on <br /> the stockpile will be avoided to maintain soil viability (Vogel, 1987). <br /> Stockpiled topsoil will be seeded, following initial removal, with a temporary seed mixture (Table <br /> E-2) that will establish quickly and prevent topsoil loss due to wind and water erosion, as <br /> discussed below. This seed mixture was provided by NRCS. All topsoil will be rehandled as little <br /> as possible until final placement on the regraded areas. <br /> Final Grading, Slopes, and Drainage <br /> Grading will occur to create a final topography appropriate to the final land use (Figure F-1). All <br /> affected lands will be graded in a manner to control erosion and siltation to protect areas outside <br /> the affected land from slides and other damage. <br /> The mining and reclamation plan is designed to backfill the pit to the maximum extent practical <br /> in order to reduce the remaining highwalls and to account for wildlife safety. A portion of the <br /> fines material stockpiled at the top of F1 will be hauled or dozed to backfill the western extents <br /> of the pit and to eliminate highwalls in this area and to create a smooth slope between the pit, <br /> native ground and the stockpile. Maximum final slopes including highwalls have been designed <br /> to be compatible with the configuration of surrounding conditions and the final land use, as <br /> required per Rule 3.1.5. <br /> Hitch Rack Ranch Quarry Permit Application <br /> March 9,2018 E-5 <br />
