These lines will <br /> • <br /> • be closed where necessary by the property lines oS the tract to <br /> form. polygons (the zones) or purposes of determining density <br /> within the tract. An increase in density means that the maximum <br /> • . allowable density in the polygon closest to the designated buffer <br /> will be 50a of the maximum allowable density of the polygon <br /> • second closest to the designated buffer, which shall be 50% of <br /> the maximum allowable density of the polygon third closest to the • <br /> designated buffer,, assuming sufficient distance exists to create <br /> such :polygons. Allowable but unused density in any polygon may <br /> be used in the polygon. Surthest from the designated buffer. <br /> (3) The maximum allowable impervious surface <br /> shall also decrease as one approaches the designated buffer. The <br /> maximum allowable impervious surface in the polygon closes to the <br /> • designated buffer will be 50% of the maximum allowable Impervious <br /> surface of the polygon second closest to the designated buf4rer, <br /> which shall be 50x of the maximum allowable impervious surface <br /> the polygon third closest to the designated buSSer, assuming <br /> • • <br /> sufficient distance exists to create such polygons.. Allowable <br /> but unused impervious surface may be used in the polygon furthest <br /> from the designated buffer. <br /> (4) Any polygon with less than five acres shall <br /> be merged with the polygon adjacent to it and further from the <br /> designated buffer, and calculated as part of the area in that <br /> polygon. <br /> (5) Where a building lies in two polygons, it <br /> shall be construed to lie in the polygon furthest from the <br /> designated buffer in which it partially lies. Where the location <br /> of buildings are not designated on the site plan, they shall be <br /> deemed to lie on the :front setback line of the lot and at a point <br /> halfway between the adjacent lots. <br /> - <br />
