[Added 4-18-1978[1]]
A. 
It is the Town Board's intent to provide for the health, safety and welfare of residents and visitors of Islip on both the mainland and the barrier beach known as "Fire Island" by the protection of the barrier beach through this ordinance from development which does not take into consideration the natural function of a barrier beach and its ecological systems.
B. 
The Town Board hereby states its concern about life and property due to the overdevelopment of Fire Island both on the mainland and the aforesaid barrier beach. The Town Board is in full agreement with the United States Department of the Interior's general intent for preservation of Fire Island as a unique resource for present and future generations, consistent with the General Management Plan for the Fire Island National Seashore.
C. 
The Town Board hereby designates the Planning Board and the Zoning Board of Appeals to review the permitted uses enumerated in § 68-137 and § 68-137.1 pursuant to the intent of this ordinance.

A. 
No in-ground swimming pools, in-ground wading pools, in-ground water use structures of this or a similar type shall be erected. As stated in the Town of Islip Comprehensive Plan, Fire Island should continue to serve two major functions:

The Town Board finds that the above uses therefor represent an overintensification of property use on Fire Island in light of the high development density of the area, an intrusion on the peace and tranquility of living styles on Fire Island and an unnecessary accessory use to a residential dwelling in light of the swimming and bathing opportunities readily available to all residents of the beach.

(3) 
The temporary special exception is not transferrable and shall terminate automatically upon the transfer of the property; the death of the individual having the medical hardship; or upon any violation of this section.
