EXISTING TEXT <br />(a) The size of a perennial stream buffer shall be measured from the annual <br />average stream banks perpendicularly for a distance of 50 feet plus 4 times the <br />average percent of slope of area adjacent to the stream. This slope shall be <br />calculated by measuring a distance of 250 feet from the center of the stream. The <br />percent of slope for this distance shall serve as the determining factor. However, <br />the maximum distance shall not exceed 120 feet from the edge of the stream. <br />St <br />~~.~,, <br />., <br />+. <br />Pre-development elevation of Point 1 in feet = E3 <br />Pre-development elevation of Point 2 in feet = E2 <br />S = E2 - El (fee(J x 100 <br />250 feet <br />(b) The size of an intermittent stream buffer shall be measured from the annual <br />average stream banks perpendicularly for a distance of 35 feet plus 4 times the <br />average percent of slope of area adjacent to the stream.
