These materials were observed to be highly effective, however, more energy dissipaters <br /> placed at a closer spacing would greatly enhance overall channel stability. In October, <br /> enough Georidge material was ordered to install about fourteen more dissipaters, <br /> however, early November snows prohibited installation of these materials. These will <br /> be installed during the spring of 2001. <br /> The total cost of the Ditch 8 Reconstruction Project was $23,363.50 <br /> South Basin Road Reclamation Project <br /> The remaining haul roads leading from the Lamphouse to Mines 1, 2 and 4, as well as <br /> the Huntsman Ridge Road, were reclaimed in 2000. Road A, which extends from the <br /> main gate near the confluence of Coal and Dutch Creeks to the Forest Service gate <br /> about 100 yards west of the Lamphouse, was not reclaimed. Road A is owned by Mid- <br /> Con LLC., who had requested that it remain in its operational condition. <br /> The Bid Specifications for the haul road reclamation called for removing all culverts, <br /> constructing 101 rolled dips and 18 low water crossings, and reversing the road gradient <br /> from an incline toward the cut slope to an incline toward the outslope at seven percent. <br /> Following grading, the road surface was to be ripped to a depth of fifteen inches on <br /> eighteen inch centers. The rip was to be conducted so that the blade of the dozer was <br /> angled into the cut slope of the road and downhill at about a thirty degree angle. This <br /> angle was chosen because when the average fall of the road was considered in <br /> conjunction with the reversed gradient of the roads, the rip would be nearly <br /> perpendicular to the flow of runoff water, and would most effectively intercept the <br /> surface runoff. Following ripping, the roads were to be fertilized, seeded and mulched <br /> with certified weed free straw at two tons per acre. <br /> The Bid Specifications for the Huntsman Ridge road called for ripping of the road <br /> surface, removal of two existing culverts and construction of rolled dips to channel <br /> runoff from the road. The road was fertilized, seeded and mulched following ripping. <br /> Two significant field changes were made to improve the overall quality of the Project. <br /> The slope of the reversed road gradient was increased from the specified seven percent <br /> to an average of eight and one half percent, and the number of rolled dips was <br /> increased from 101 to 153. The final Project cost was $143,895.00. <br /> During the 1996 road reclamation project, it was necessary to traverse the ripped road <br /> segments with trucks a number of times in order to fertilize, transport mulch to the <br /> ripped areas, and to apply the mulch. This amount of truck traffic resulted in a slight re- <br /> compaction of the ripped road surface, a situation which was desirable to avoid when <br /> reclaiming the steeper South Basin roads. In order to minimize the post-rip traffic, the <br /> Bid specified that the Contractor could only access the road once with a truck and trailer <br /> following ripping. In order to accommodate this constraint, fertilizer was applied to the <br /> roads following grading, but prior to ripping. The straw mulch was pre-placed along the <br /> roads prior to initiating earth work. The mulch was distributed in conjunction with the <br /> seeding after ripping by towing a two axle trailer holding a mulch blower up the road <br /> 6 <br />
