• ~ks and Gesso, LLC EXHIBIT E: Reclamation Plan The proposed post-mining land use for the 124'h Estates Sand and Gravel Mine will be as a developed water resource -approximately 1,000 acre feet of water storage capacity to be conveyed to the City of Brighton. The proposed reservoir is located adjacent to the Fulton Ditch and to US Hwy 85. Most surrounding land is within an agricultural zone district of unincorporated Adams County; although the area of the mine and the proposed water storage facility is being annexed by the City of Brighton and will be placed within an industrial zone district. Mining activity will clear residual sand and gravel deposits from the historic mine and expose underlying bedrock. Reclamation of the site will utilize on-site materials for backfill to create stable slopes and a clay lining of the reservoir, isolating it from surrounding ground water. Materials Handling As mining is nearing completion in Area 1, the Operator will begin to backfill with clay substrate and settled fines, along the wall of the mine to create appropriate slopes and a clay liner for the water storage reservoir. Final Grades 200,000 to 250,000 yards of material will be used to backfill and create appropriate slopes for the lining of the reservoir. This backfill and liner will be constructed using fine, settled solids from dewatering and washing operations and claystone bedrock, ripped from the floor of the pit. Estimating 10 percent waste from washing operations, up to 50,000 yards of settled fines will be available for backfill, necessitating the removal of 3 to 4 feet of bedrock material from the floor of the pit to complete reclamation. The tops of reclaimed slopes will be no less than 20 feet from north, east, and south property lines, creating a 20 foot bench along these property boundaries, 124 Estates -Regular 112 Application 01029.WD 124° Estates Partners ip August 2001
