agricultural suitability of the property. Because replacement of the topsoil will not enhance the agricultural suitability of the property, the topsoil may be removed from the site per San Joaquin County Development Title 9-1415 . 3 (g) . The topsoil will be preserved by making it available for sale to others or by deepening the existing topsoil in the setback areas . Stockpile Volume : Stockpile volume will vary due to varying market demand for different soil types . Stockpile locations : Stockpile locations are shown on the Excavation Site Plan. Erosion of Stockpiles : Stockpile slopes will not generally exceed 2 feet horizontal to 1 foot vertical . In addition, the clayey soils and low rainfall climate combine to preclude erosion in stockpiles . 3 . Type of Mining - Overburden/Waste/Ore: The proposed type of mine is a combination of quarrying to remove overburden, and dredging to remove the sand, which is below the water table . Near surface topsoil and sedimented and clayey subsoil, which lie above the sand will be excavated from the site using scrapers, excavators, draglines, or other means . Excavated soil will be loaded into rubber-tired scrapers, bottom dump trailers, haul trucks or other transport, and directly sold, or placed into stockpiles . No blasting is proposed. The contour created by the excavation will be the final contour required in the reclamation plan. Cuts will not create interim slopes that need backfilling during reclamation. The final contour will be created as the excavation progresses . Slopes will be excavated to finish grade. Below the water table, a bucket type "sky-line" dragline (or equivalent) will be utilized to excavate sands to a depth averaging approximately 60 feet below the present surface . Slopes under water will not exceed 2 feet horizontal to 1
