The US Army Corps of Engineers has generated proposals for an offshore steel and concrete barrier that would wall off New York Harbor from the Atlantic Ocean at an estimated cost of $20 billion. In the aftermath of disasters such as Hurricane Sandy, the barrier stretching nearly 2,150 square miles along the New York Harbor would help prevent an ocean surge from flooding the metropolitan region.
The proposal presents various options, including a five-mile long barrier between Sandy Hook, NJ and Breezy Point in the Rockaways; a barrier between Staten Island and Brooklyn with five gates across the entrance points to Jamaica Bay, Pelham Bay and Arthur Kill; or a set of berms and sea walls along low-lying areas of New York and New Jersey’s waterfronts.
As the process matures, the Army Corps will look for public input on key issues that should be addressed during the environmental impact study.
