Referring to the acreage table <br /> from Task #1, it is seen that 113.6 acres of <br /> mild slopes remain to be revegetated, <br /> however, the original estimate allowed for <br /> 34 acres of road surfaces that would not be <br /> resoiled. Ditches and berms have merit in <br /> the portal areas to keep water off the steep <br /> spoil slopes. DMG is not resoiling any of <br /> the road surfaces. Subtracting this acreage <br /> from the 113.6 acres leaves 79.6 acres to be <br /> resoiled At an average cost of$984.5 per <br /> acre, this results in a remaining cost of <br /> $78,366. Therefore, the DMG credit is <br /> $241,198 - $78,366- $8,860 = $153,972. <br /> 12-13 Seal Portals and Fan $94,924 $94,924 $0 $0 $0 $0 No remaining work.
