In order to do any construction work on bulkheads within the boundaries of Fire Island National Seashore, a National Park Service is required. The NPS permit is in addition to the appropriate permit from New York State (usually the Tidal Wetlands permit from NYS DEC) and the 404 permit from the . Each permit is necessary to provide oversight for the resources that each agency is mandated to protect.
Particularly on the bay side of Fire Island, property owners have constructed individual bulkheads with the intention of protecting their property against erosion. However, bulkheads negatively impact both natural ecosystem processes, and private property that is not bulkheaded.
Bulkheads replace natural formations landward of them and prevent upland sand sources from entering the littoral drift system, causing sediment starvation downdrift, and shifting negative effects to neighboring land. The interaction of waves with a structure increases wave reflection and turbulence, nearshore current velocities, and sediment activation and transport at the base of the structure.
Continuing past practices that have been shown to be in conflict with scientific understanding of best management practices is imprudent and short sighted. Knowledge about bay shore processes is ever increasing and new methods of shoreline protection that are more respectful of and responsive to natural systems, and that address erosion concerns of property owners are being developed and tested in coastal environments around the world. Park managers, in cooperation with universities and other federal and state agencies, are monitoring these developments and supporting research in order to ascertain an environmentally sensitive approach to these erosion concerns.
