Project Summary

The US Army Corps of Engineers New England District contracted LAND Remediation, Inc. to perform dredging services on the Westport River Federal Navigation Channel in Westport, MA.  The purpose of the project was to restore the controlling depth within the horizontal limits of the federal navigation channel to its original design depth of -9 feet mean lower low water. 

The harbor channel was overdue for maintenance being in a very dynamic body of water and having not been dredged in nearly 20 years.  Over 55,000 cubic yards of shoaled sediment was removed mechanically, returning more than 12 acres of the federal channel to a navigable waterway between the harbor entrance at Halfmile Rock to the Inner Harbor Reach.  The dredged sediment was transported via dump scow to the Westport Harbor Nearshore Placement Site located approximately 1.5 miles east of the harbor entrance, and about 1,000 feet south of Horseneck Beach for permitted open water disposal. 

This location provided a beneficial re-use of the sandy sediments as it was within the littoral zone of Horseneck, Cherry and Webb Beaches, and the material would replenish these beaches that have been experiencing coastal erosion in recent years by the natural and localized circulation of tides and currents.
