Class II Water Supply Watershed area as classified by the <br /> State of North Carolina, or <br /> <br /> a Class IV Water Supply Watershed as classified by the <br /> <br /> Uncovers less than one (1) acre in an area in locations outside <br /> <br /> or Class IV water supply Watershed, must be in compliance with <br /> all other applicable land-disturbing requirements contained in <br /> other ordinances or building development standards adopted by the <br /> <br />d. Basic Control Ob4ectives - A Plan may be disapproved pursuant to <br /> <br /> following control objectives: <br /> <br /> to severe Erosion, and off-site areas which are especially <br /> vulnerable to damage from Erosion and/o~ Sedimentation, are <br /> to be identified and receive special attention. <br /> 2. Limit Time of Exposure - All Land-Disturbing Activity is to <br /> <br /> feasible time. <br /> 3. Limit Exoosed Areas - All Land-Disturbing Activity is to be <br /> planned and conducted to minimize the size of the area to <br /> be exposed at any one time. <br /> <br /> Sediment loss during the period of exposure. <br />f. Control Sedimentation - All Land-Disturbing Activity is to be <br /> planned and conducted so as to prevent off-site Sedimentation <br /> damage. <br /> <br /> sufficient to cause Accelerated Erosion of the receiving <br /> <br />Section 7 - Mandatory Standards for Land-DisTurbing Activity <br /> No Land-Disturbing Activity subject to the control of this Ordinance <br />shall be Undertaken except in accordance with the following mandatory <br />standard: <br />a. Buffer Zone <br /> 1. No Land-Disturbing Activity during periods of construction <br /> or improvement to land shall be permitted within the Buffer <br /> Zone, as defined below. Visible Siltation must not <br /> discharge into the Buffer Zone. This subdivision shall not <br /> apply to a Land-Disturbing Activity in connection with the <br /> construction of facilities to be located on, over, or under <br /> a lake or natural watercourse. <br /> 2. Unless otherwise provided, the width of a Buffer Zone <br /> begins and is measured five feet from the edge of the top <br /> of the bank of the watercourse to the nearest edge of the <br /> disturbed area. Natural or artificial means of confining <br /> visible Siltation must be placed, constructed or installed <br /> outside the undisturbed Buffer Zone. <br /> b. Graded Slopes and Fills - The angle for graded slopes and fills <br /> shall be no greater than the angle which can be retained by <br /> vegetative cover or other adequate Erosion control devices or <br /> structures. In any event, slopes left exposed will, within 15 <br /> Working Days of completion of any Phase of Grading, be planted or <br /> otherwise be provided with Ground Cover, devices, or structures <br /> sufficient to restrain Erosion. <br /> c. Ground Cover Whenever more than one (1) acre [except as <br /> provided in Section 6(a) (2) and (3)] is Uncovered, the Person <br /> conducting the Land-Disturbing Activity shall install such <br /> Sedimentation and Erosion control devices and practices as are <br /> sufficient to retain the Sediment generated by the Land- <br /> Disturbing Activity within the boundaries of the Tract during <br /> construction upon and Development of said Tract, and shall plant <br /> or otherwise provide a permanent Ground Cover sufficient to <br /> <br /> <br />
