To reclaim these areas, all concrete structures and associated piping should first be <br />retnoved. The pond embankments may be used to fill the excavated interior of <br />ea<:h pond. Backti7l should be in uniform layers compacted to approximately 8546 <br />of maximum Standard Proctor Density. The area should be left free draining and <br />should be uniformly covered with topsoil to bring the final grade to its approximate <br />original contours. Seeding and mulching should be in accordance with the MdcR <br />plan. <br />D. Reclamation oP the Access Road through the Rock Cut: <br />The proposed access road passes through various rock formations from Station.7+00 <br />to Station 21+00. The rode appears to be a sound sandstone in this reach. The <br />proposed toad cut through this area will require blesting~. The rock removed from <br />the road cut will be used as riprep Yor the ponds and spillway channels. <br />That portion of the access road which passes through rock should be backfilled with <br />the same rock which was removed for use as riprap. Broken concrete can be used <br />to make up any losses as required Rock, gebians or concrete should be placed in <br />such manner as to provide as few voids as possible between the individual pieces; <br />the idea is to form as dense a section es possible. Dirt, gravel, small rocks, or <br />mortar can be used to till the voids between adjacent rock pieces. <br /> <br />A. GeneraL• <br />Structural materials such as broken pavement, broken concrete, scrap timber or <br />other miscellaneous items which may be deemed unsalvageable shall be disposed of <br />at designated on~ite disposal areas as permitted by the State of Colorado. If this <br />is not passible, such materials shall be removed from the site end transported to <br />the nearest local landfill site for disposal <br />B. On Site Disposal Locations: <br />Ideal locations for disposing of materials on site would be within Freshwater Pond <br />No. 1 (FW#i), Runoff Pond No. 1 (MB#1), and Runoff Pond No. 2 (MB#2). 4ll three <br />of these ponds will require fi71 to return Lhe land to its approximate original <br />contours. In addition, these ponds either have a natural clay barrier, as is the case <br />Por MB#1 and FW#1, or an installed clay liner, as is the case Por MB#2. This will <br />help minimize seepage into the surrounding ground water system. <br />Refuse placed in these areas during the reclamation process should be covered with <br />approximately Your (4') to five (5') feet of fill, most of which would come from the <br />surrounding pond embankments themselves. <br />C. Road and Parking Lot Surfaces: <br />Any surfaces containing asphaltic crompounds (such as the penetration macadam <br />surface or the bituminous concrete pavement surfaces) shall be removed and <br />disposed of in the designated disposal areas. AlI such surfaces should be removed <br />to the subgrade or base course levels. <br />12 <br />
