Specifications include, but are not limited to: The proposed project includes approximately 0.3 acre of disturbance, and consists of the abatement of a hazard posed to the Coleman residence by a deteriorating highwall immediately adjacent to the residence and mine-related drainage at the house-seat elevation. The hazards posed by the deteriorating highwall will be addressed by the construction of an 8’ tall unreinforced concrete block wall. The backfill behind the wall, rather than being banked against the slope as per normal procedure, will be slightly negatively sloped back to the highwall, forming a shallow pocket to collect any rocky debris from above the wall. The portion of the highwall immediately behind the retaining wall will be protected from weathering by the rock backfill. The mine-related drainage impacting the portion of the residential house-seat between the residence and the highwall will be collected by the retaining wall subdrain. The drainage collected by the subdrain will be carried to Peter Fork by an erosion-control blanket ditch. All excess earthen material generated by excavations at this site will be placed in an on-site fill area. Revegetation will be achieved by means of the standard AML Residential Lawn Seed Mix.
