' To reclaim these areas, all concrete structures and associated piping should Pirst be <br />removed. The pond embankments may be used to fill the excavated interior of <br />' each pond: Backfill should be in. uniform layers compacted to approximately 85% <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 M6cR <br />plan. <br />D. Reclamation of 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 rock appears to be a sound sandstone in this reach. The <br />proposed road cut through this area will require blasting. The rock removed from <br />the road cut will be used as riprap for 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, gabions or concrete should be placed in <br />such manner eS to provide as few voids as possible between the individual pieces; <br />' the idea is to form as dense a section as possible. Dirt, gravel, small rocks, or <br />mortar can be used to fill the voids between adjacent rock pieces. <br />YL RECOMMENDATIONS FOR THE RECLAMATION OF OTHER RELATED SURFACE <br />FACILITIES - - - - - - <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 />t at designated on-site disposal areas as permitted by the State of Colorado. If this <br />is not possible, such materials shall be removed from the site and 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#1), Runoff Pond No. 1 (MB#1), and Runoff Pond No. 2 (MB#2). All three <br />of these ponds will require fill to return the land to its approximate original <br />' contours. In addition, these ponds either have a natural clay barrier, as is the case <br />for MB#1 and FW#1, or an installed clay liner, as is the case for MBir2. 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 four (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 compounds (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. 911 such surfaces should be removed <br />to the subgrade or base course levels. <br />1 <br />' 12 <br />
