Hardwick Court Channel Improvement project design replaced approximately 150 ft of 60” sanitary sewer and a concrete spillway crossing Maline Creek.  The existing sewer pipe and spillway had created a six foot drop in the channel grade with a large scour pool at the bottom of the drop. The project spans approximately 55 feet upstream and 90 feet downstream of the existing sanitary sewer crossing at Hardwick Court.


Proposed improvements consisted of new manholes and sewer pipe, reinforced concrete spillway, rock scour pool armor immediately downstream of the spillway, composite revetment bank stabilization, and a retaining wall using large block hollow core modular retaining wall systeml.
