t <br /> • 2.05.3(3 ) (c) <br /> The reclaimed access roads were closed to vehicular <br /> traffic and natural drainage patterns were restored. All culverts <br /> were removed. Roadbeds were ripped, plowed, and scarified. Fill <br /> slopes were rounded or reduced and shaped to conform the site to <br /> adjacent terrain. Cut slopes were shaped to blend with the natural <br /> contours. The regraded areas were covered with topsoil and <br /> revegetated in accordance with section 2 .05.4 . <br /> Haul Road <br /> Mining Area 3 requires one haul road to connect the <br /> new mining area with the existing haul. The new haul road will <br /> connect with the existing haul road between mining areas 1 and 2. <br /> This haul road is approximately 2500 feet long. It is designed to <br /> be 30 feet wide. The haul road has a maximum pitch grade of 15% <br /> which extends for approximately 250 feet. The typical grade of the <br /> haul road is 4%. <br /> Topsoil will be salvaged from a 50-foot wide <br /> corridor along the alignment of the haul road prior to the start of <br /> construction of the road. In cut and fill sections the striping <br /> width will be increased appropriately. Borrow ditches typically <br /> two feet deep and eight feet wide will be excavated on each side of <br /> the road surface to provide material for the subgrade of road. <br /> Four to six inches aggregate base course will be used to surface <br /> • the road. A Colorado State Department of Highways Specification, <br /> Class 3 aggregate will be utilized. A section view of the road is <br /> shown of Drawing No. 131. <br /> Cut and fill slopes will be constructed using 2H: 1V <br /> slopes. The haul road is constructed on grade without any <br /> significant fills . The haul road crosses two drainages. Two <br /> culverts will be placed under the haul road where it crosses the <br /> drainages at haul road stations 17+50 (CMP #14 ) and 24+75 (CMP <br /> #13) . The culvert and borrow ditch sizing calculations are <br /> presented in Exhibit 9 . <br /> To provide erosion control, the borrow ditches and <br /> cut and fill slopes will be seeded. The seed mix used will be that <br /> used to stabilize the topsoil stockpiles or other appropriate seed <br /> mix approved by the Division. Broadcast seeding will be used. <br /> The haul road will be constructed in accordance with <br /> the performance standards under Rule 4 .03. 1 (3) . <br /> By a letter dated September 15, 1993, the <br /> landowners, Roy and Betsy Davis, explained the reasons they wanted <br /> the haul roads on the property left in place. They indicated they <br /> did not want the roads on the property to be narrowed to a width of <br /> 15 to 20 feet. They view the thirty foot wide roads as an asset <br /> • that can be used as an important part of their ranching operation. <br /> 2.05-7ii January 1994 <br />
