Hurricane Sandy breached the Barnegat Peninsula in October of 2012. In 2018, the U.S. Army Corps of Engineers completed the dune and berm system in the same location. Work is designed to reduce the risk of damages from future coastal storms.
The Shallow Draft Dredge MURDEN clears shoaling from Barnegat Inlet, N.J. in April of 2014. The vessel was designed by the U.S. Army Corps of Engineers' Marine Design Center in Philadelphia and is based out of Wilmington, N.C. Barnegat Inlet requires dredging to provide reliable maritime navigation for the U.S. Coast Guard and a large fishing fleet consisting of full-time commercial, charter and recreational vessels.
In 2017, USACE completed periodic nourishment of the Cape May to Lower Township project (Photo from February of 2017).
Long Beach Island Coastal Restoration
Gurney Avenue Before and After - initial construction of an elevated 25 to 180-foot wide berm was completed in 1991 as part of the Cape May to Lower Township project. Cape May City beaches were often in a severely eroded state prior to the initial construction and periodic nourishments in subsequent years.

Coastal Storm Risk Management Program

The New Jersey Atlantic Ocean coastline extends from Sandy Hook to Cape May, New Jersey, covering a range of approximately 130 miles.  The New Jersey coastline from Manasquan Inlet south to Cape May Point lies within the boundaries of the U.S. Army Corps of Engineers Philadelphia District while from Manasquan Inlet north is under the jurisdiction of the New York District. 

Nine federally authorized coastal storm risk management projects have been constructed along the Philadelphia District’s New Jersey coastline (including Oakwood Beach located along the Delaware Bay coastline). The Philadelphia District oversees the entire coastline in the state of Delaware as well. The District has constructed six coastal storm risk management projects along the coastline of Delaware (including Broadkill Beach on the Delaware Bay coastline). These projects typically involve the construction of dune and berm systems and are designed and built to reduce the risk of storm damages to infrastructure. New Jersey and Delaware projects and their respective statuses are listed below.
