CABARRUS COUNTY ZONING ORDINANCE <br />5) The determination that a waterbody or stream indicated on a USGS Map or <br />NRCS soil survey map does not exist must be concurred by the NCDENR Division of <br />Water Quality and/or the US Army Corps of Engineers. <br />6) The Waterbody Buffer Zone shall be determined and clearly delineated on <br />site prior to any development or pre-development activity occurring in order to <br />protect the required buffer from encroachment or damage. <br />7) The waterbody buffer shall be maintained as follows and shall be shown on <br />all site plans or subdivision plats related to the project submitted for review, <br />including soil and erosion control plans: <br />(a) The size of a perennial stream or Class 1 waterbody buffer shall be <br />measured from the annual average stream bank, perpendicularly for a distance of <br />50 feet plus 4 times the average percent of slope of area adjacent to the stream. <br />This slope shall be calculated by measuring a distance of 250 feet from the center <br />of the stream. The percent of slope for this distance shall serve as the determining <br />factor. However, the maximum distance shall not exceed 120 feet from the edge <br />of the stream. For Lakes, ponds or impoundments, the buffer shall be computed <br />using the high water elevation in place of the stream bank in the calculation. <br />Top of 1 <br />. . <br />.. <br />Stream Bank ~•' ' ~" • ' • ~ • <br />• .r. -.-~~-•- ,r ~~, . <br />I _ 4r~ <br />1 ..I ) ti• • <br />1 ~ Y. <br />I k F91~-.~t t,: ,~ 1T. ~ ~ A <br />1 .' -~• <br />1 <br />1 1~.}~• v 111 <br />1~ ~ ~ i\ 1 ' 1 ~~ ~~ y+ <br />' ~~• ~ : ~~ <br />,i i g~ -;t i, i <br />_ <<~ I ~ <br />'~ ._ ~`'" . _ 50 feet ... 4 x slope . <br />Width = [50 + (4 x S)] <br />Minimum width: 50 feet (areas with fiat slopes) <br />Maximum width: 120 feet (areas with steep slopes) <br />4-6 <br />Attachment number 3 <br />G-2 Page 184 <br />
