(a) The Board finds that: .'• <br /> (1 ) Soil and pollutants carried overland, primarily from roads, <br /> ' trails, and land disturbing activities, can be effectively <br /> trapped by leaving a relatively undisturbed strip of <br /> vegetation parallel and adjacent to the watercourse. - • <br /> - (2) Properly managed overland water flow can be directed into <br /> WM. this buffer area in a manner that will reduce velocity <br /> and cause dispersion of the water. • <br /> • (3) Sediments and associated pollutants carried by the water <br /> • • <br /> • will settle out as a result of this slowing and dispersion • <br /> . - . process. • • - <br /> • . (b) Developments on lots within the C, R-40, B- 5, or WM-3 zoning <br /> districts shall , if any of the watercourses identified in this subsection are <br /> located in whole or in part within the lots so developed, contain a designated <br /> buffer area adjacent to such watercourse. The buffer area boundaries shall be <br /> demarcated by a line connecting the points on either side of a watercourse <br /> located as follows: <br /> Cl) Creeks and tributaries (.i.e. , permanent streams flowing directly into <br /> • University Lake and permanent streams flowing into such streams). <br /> Measure along a line running perpendicular to the edge of the flood- <br /> ' 14h; plain (or if *no floodplain has been demarcated, the center of the <br /> stream) fifty feet from the edge of the floodplain (or if no flood <br /> plain has been demarcated, from the edge of the water) plus an <br /> • additional dittance equal to: <br /> • • 4 x slope x 100 . <br /> • <br /> • where "slope" is expressed as a percentage derived by dividing by 100 <br /> the rise inielevation between the floodplain. boundary line (or if no • <br /> floodplain has been demarcated, the edge of the water) and a point <br /> one hundred feet from-that point along the above-described perpendicula <br /> line. <br /> (2) Intermittent streams flowing into creeks and tributaries.. Measure <br /> along a line running perpendicular to the centerline of the inter- <br /> mittent stream fifty feet from such stream centerline. <br /> (3) Intermittent streams flowing directly into University Lake. Measure <br /> aiong----a4ine-runni-ng-perpendieul-ar-to-the-centerl-ine-of-the-i-ntermittt <br /> stream one hundred feet from such stream centerline. <br /> (.4) Intermittent streams flowing into streams which flow directly into <br /> University Lake. Measure along a line running perpendicular to the <br /> centerline of the intermittent stream fifty feet-from such stream <br /> centerline. <br /> • <br /> • <br />
