The U.S. Army Corps of Engineers’ Philadelphia District received funding from the Infrastructure Investment and Jobs Act (IIJA) for repairs at the Indian River Inlet in Sussex County, Delaware. USACE awarded a contract to Agate Construction Co., Inc. of Egg Harbor Township, N.J. to repair a portion of bulkhead and to sand-tighten a portion of the south jetty at Indian River Inlet in Sussex County, DE. The contract called for the repair of a failed section of bulkhead/revetment along the interior north shoreline of the Indian River Inlet. A deep scour hole caused by swift tidal currents within the inlet has undermined the slope of the “stabilized” shoreline and landward infrastructure. Additionally, the contract called for sand tightening a 215-foot section of the south jetty. This work involved installing steel sheet piling to reduce the amount of sand migrating into the inlet.

USACE conducted geotechnical and structural analyses for repair work on the north jetty. This has not been awarded yet and is currently under design.
