Final grading of the floor areas shall provide for a smooth surface and the prescribed gradations <br />of 2 percent for their surface drainage. Roads servicing the area shall be located, shaped, and <br />graded. <br />Draina¢e: <br />Reclamation shall give due regard to proper drainage of the affected area. Upon completion of <br />the mining and reclamation, the land shall be left in a safe condition that provides drainage <br />structures sufficient to prevent water pockets or undue erosion and control surface runoff in <br />excess of historical flow. Natural drainage channels outside the mining area will be preserved <br />and used whenever possible. In those areas where natural drainage is interrupted, French drains <br />and/or culverts will be installed as required, to assure flow of runoff water through the area. <br />Reconstruction of the Jackson Gulch drainage as previously mentioned herein will be completed <br />after cessation of mining activities. <br />Toa Soil• <br />There is a small quantity of topsoil suitable for revegetation and this will be stockpiled and <br />preserved for use in reclamation on the property. Topsoil will be used with other available soils <br />and decomposed rock to provide a minimum of 12 inches to 18 inches of cover on the floors and <br />stockpile areas. <br />Revegetation• <br />A revegetation program shall be accomplished with the assistance of the designee of Jefferson <br />County or the Colorado Mined Land Reclamation Department. The revegetation program will <br />involve utilization of available topsoil, and the selection of appropriate plant species, locations <br />for planting, and maintenance procedures. In those areas where revegetation is part of the <br />reclamation plan, land shall be revegetated in such a way as to establish a diverse, effective, and <br />long-lasting vegetative cover that is capable of self-regeneration and at least equal in extent of <br />cover to the natural vegetation of the surrounding azea. The vegetation program to be <br />implemented will satisfy the following minimum standards: <br />1. For the back filled benches and at other locations, bare-root stock bushes and trees <br />will be planted. The plant species used will be selected from the annual list of the <br />Jefferson County 4 -Has provided by the Colorado Division of Forestry. The <br />spacing of the trees and shrubs will be random and staggered to a minimum of 20 <br />feet apart. <br />2. For slopes, benches and the quarry floor one of the following seed mixture shall <br />be planted: <br />a.) Seed mix to be provided by Jefferson County designee <br />OR <br />b.)
