Car f-k,e) p-Co <br /> 160 (6) Where two or more polygons of the same class. <br /> as in the polygon closest to the designated buffer, are created <br /> • by two distinct, non-contiguous designated buffers, the units <br /> 1 <br /> attributable to that class shall be distributed in proportion to (: <br /> the developable area in each polygon. <br /> (7) Where a designated buffer lying more than <br /> 3.200 feet from a tract would result in the creation of a polygon. .6 .., <br /> that designated buffer shall be ignored for purposes of applying <br /> this subsection. Furthermore, where two or more designated <br /> buffers lie in a general direction, such as on the west side of <br /> the tract, only the designated buffer closest to the tract will <br /> be considered in determining the shape of the polygons. <br /> • (8) For purposes of applying this section, <br /> • adjacent parcels in common ownership and not developed at the <br /> time this provision is enacted shall be joined. • <br /> (9) In the event, that after applying the above <br /> ' • ' provisions, a tract is composed :ot only one polygon, then <br /> . paragraphs (2) and (3) above shall be applied by substituting the <br /> number "300 feet" for each reference to "GOO feet", and "25z" for <br /> each reference to '"50 " <br /> (b) Within the context of allowing development consistent <br /> with the provisions of (a) above, buildings and imperviouss <br /> surfaces shall be sited so as to pose the least adverse impact on <br /> the watershed environment and so as to take full advantage of the <br /> assimilative capacity of the land. The first one-half (1/2) inch - <br /> of runoff from all impervious surfaces shall be detained'from <br /> reaching the watercourses through the full use of undisturbed, <br /> . vegetated areas for infiltration of the run-off. In the event <br /> that on-site infiltration is not possible, or that areas with <br /> suitable soils are not sufficient to accomplish infiltration, • <br /> • then alternative measures to control the run-off shall be <br /> employed. These alternative measures may include structural <br /> infiltration measures and retention/detention structures. <br /> • (c) Notwithstanding the density allowable in (a) above, - <br /> • . the density ofland,. both developable and undevelopable as those <br /> term& are used in this Section, lying within an area marked by a <br /> line drawn- parallel to the butter and 300 feet from it shall not <br /> exceedone unit per two acres. Furthermore, notwithstanding the <br /> • maximum allowable impervious surface in . (a) above, the maximum <br /> • alloWable impervious surface of land, both developable and <br /> undevelopable as those terms are used in this Section, lying ' <br /> • within an area marked by a line drawn parallel to the buffer and <br /> 1 300 feet from it shall not exceed 10z. Provisions regarding <br /> • constructive siting, namely subsection (a) (4) and (5) shall be <br /> applied_to-determine-the-location-of units-where-units-are shown on on the site plan. or -otherwise specifically designated on <br /> the site. <br /> Section 15-268 throush 15-269 Reserved. <br /> 1 <br /> I <br />
