Specifications include, but are not limited to: The Joey Tackett Drainage AML Reclamation Project includes approximately 0.3 acre of disturbance at a single work area. Work at the project area consists of the construction of drainage control structures in replacement of an existing system, which was constructed under a previous AML reclamation project, that has become damaged by underground mine subsidence. The previously constructed structures will be removed, and the opening, which has been created by underground mine subsidence and related soil-piping erosion into the underground void, will be sealed with a combination of polyurethane foam and flowable fill and concrete associated with construction of the replacement drainage control system. The new drainage control structures will consist of a 2'x2' rectangular concrete ditch that will run immediately adjacent to the Tackett garage/shop structure, terminating into a 24" diameter HDPE culvert immediately above the residential driveway.
