TRACE CREEK LOW-HEAD DAM REMOVAL SPECIFICATIONS

PART 1 PROJECT DESCRIPTION

1.01 The project is for the removal of a concrete encased abandoned sewer line crossing on Trace Creek in Waverly, Tennessee. The concrete encasement that surrounds the abandoned sewer line pipe extends into the stream substrate, obstructing flow within Trace Creek and functioning as a low head dam. This obstruction is impounding approximately 600 linear feet (LF) of water behind the structure and results in a 6-foot change in stream elevation within this section of stream. The proposed work will consist of removal of the concrete encased sewer line from Trace Creek, restoration of the stream bed and banks at the location of the removed sewer line, restoration/stabilization of approximately 620 LF of stream channel downstream of the removed sewer line, stabilization of streambanks approximately 180 LF upstream of the sewer line crossing. It is an American Rescue Plan Act (ARPA) American

Rescue Plan (ARP) Resource Protection Grant funded project.
