New York Harbor Storm-Surge Barrier
The New York Harbor Storm-Surge Barrier is a proposed flood barrier system to protect the New York-New Jersey Harbor Estuary from storm surges. The proposed system would consist of one barrier located across the mouth of Lower New York Bay, possibly between Sandy Hook (N.J.) and Rockaway (N.Y.), and a second on the upper East River to provide a ring of protection to most of the bi-state region. Through extensive use of floodgates, both barriers would have largely open cross-sections during normal conditions to minimize environmental impacts on the estuary and port operations. Alternatively the southern barrier could be located between Coney Island and Staten Island. A storm surge barrier at this location, although half as long, would require supplemental barriers across the entrances to Jamaica Bay and the Arthur Kill. To address the problem of sea level rise, smaller scale projects to increase seawall heights or otherwise raise vulnerable coastlines would be necessary. Thus a storm-surge barrier system combined with coastline adjustments would form a two-tiered strategy to protect the region. The barrier system could also be extended eastward, filling in the gaps between barrier islands, to protect the various communities lining the south shore of Long Island. The
