SURDIVISTORREGULATICKS AMENDMENT <br /> Amend Section IV - DAIK211 ek N4k1.4.1A1, by adding <br /> Section IV-B-9 Watershed Protection Standards <br /> IV-B-9. WATERSHED PRO1!ECT10N BUZZARDS <br /> In e ery subdivision, provision shall be made for the protection of <br /> water supply watersheds of regional importance. Lands which are <br /> within the boundaries of such watersheds shall be subdivided and <br /> developed only after proper provision is made for the preservation <br /> of vegetative buffers adjacent to streams draining to existing or <br /> proposed reservoir sites and the first one-half (1 1/2) inch of <br /> stormwater runoff from impervious surfaces is infiltrated into the <br /> soil: <br /> IV-B-9-a. picthiUty <br /> Water supply watersheds requiring special protective measures <br /> include all property located within the Muse and Cape Fear River <br /> basins outside the zoned portions of water supply watersheds <br /> designated in the Orange County Land use Plan.. <br /> IV-B-9-b. Stream Buffer Standards <br /> In all new subdivisions located within a water supply watershed of <br /> regional importance, the preliminary and/or final plat of such <br /> subdivisions may not be approved unless stream buffers are provided <br /> in accordance with the following standards: <br /> 1) Stream buffers shall be provided along all perennial streams <br /> within or bordering new subdivisions. Perennial streams are <br /> defined as those streams, creeks or other drainageways <br /> indicated by a solid blue line on U.S. Geodetic Survey <br /> quadrangle maps for Orange County. <br /> 2) The stream buffer shall be measured from the edge of stream <br /> banks for a distance of fifty (50) feet therefrom and shall be <br /> provided along both sides of all perennial streams. <br /> 3) within the stream buffer, land shall be retained in its <br /> natural state. However, disturbance to existing <br /> forested/vegetated areas maybe allowed when replaced with <br /> Vegetation resulting in comparable stormwater runoff velocity <br /> and quantity within one Cl) year from the date of <br /> installation. Where a buffer area is subject to serious <br /> erosion, an erosion resistant vegetative cover shall be <br /> established and maintained. <br /> 4) Public and private streets, bridges and railroad rights-of-may <br /> shall be permitted to cross buffer areas, but they shall enter <br /> and exit such areas as nearly perpendicular to them as <br /> Possible. The direct discharge of runoff through ditches, <br /> culverts or along roadways which cross required buffer areas <br /> Phan be controlled through infiltration, retention or <br /> detention structures, and diversion devices. <br /> IV-B-9-C.
