The Board of Trustees of the Village of Ocean Beach finds that extraordinary measures are required to protect the public health, safety and welfare in the area immediately adjacent to the Atlantic Ocean. Because of its vulnerability to flooding, erosion and possible destruction by high winds and hurricanes, this area is not suitable for residential construction. In keeping with the General Management Plan of the Fire Island National Seashore designating a Dune Development District, federal flood hazard legislation and the objectives of the Village of Ocean Beach, these special regulations are hereby enacted.

The Dune District shall consist of all lots that are within or on the Dune District boundary line shown as such on the amended Zoning Map of the Village of Ocean Beach. The southerly boundary line shall be the mean low tide line, and the northerly boundary line shall be 40 feet landward of the primary natural high dune crest. Where breaches exist in the dune form, a line has been established that represents the general trend in the dune crest and delineates a zone of dynamic dune formation. This district is also based upon the Federal Flood Insurance Administration Flood Hazard Boundary Map Zone V-7 (areas of special flood hazard, with velocity, that are inundated by tidal floods) and the Dune District boundary as defined and mapped by the Fire Island National Seashore. The natural high dune crest line shall be confirmed by a licensed surveyor and so indicated on a plot survey attached to an application for a building permit and shall reflect the physical location of the crest of the high dune as of the date of such survey. If there is a conflict at the time of application concerning the location of the high dune crest among the surveyed line, the Zone V-7, Village Oceanfront Dune District and the Fire Island National Seashore Dune District, the most northerly line shall govern.

No structure shall be erected or used or occupied by any person except as an elevated pedestrian dune crossing or a fence of a type approved by the Board of Trustees which is designed to hold or increase the dune. The purpose of this restriction is to preserve the ecology of the dunes and grasses and by doing so to safeguard life and property in the Village of Ocean Beach.

Existing uses within the Oceanfront DD Dune District shall not be expanded. In the event that a natural disaster or other cause destroys any existing structure within the Oceanfront DD Dune District, reconstruction of any structure so destroyed may be made subject to the provisions of the Zoning Law and Building Code[1] and the approval of the Fire Island National Seashore.
