lands;

of adjoining properties; and
D. To diminish the amount of runoff and other pollution
into waterways, inlets and the Great South Bay.

This district shall comprise all property regulated
by the New York State Department of Environmental Conservation or
as identified by the Town of Islip based on inspection as wetlands
or adjacent buffer areas. Unless a greater buffer area has been established

yield shall be based upon the following:

as wetlands or adjacent buffer areas shall be based upon one dwelling
unit per 80,000 square feet of area, excluding underwater land.
(2) Yield for that portion of the property not designated
