Article 6: Development Standards 107 <br /> Section 6.15: Soil Erosion and Sedimentation Control245F <br /> M(d) Materials being used as fill shall be consistent with the most current <br /> version of North Carolina Administrative Code Title 15A Subchapter 13B <br /> Section .0562 (Beneficial Fill) unless the site is permitted to operate as a <br /> landfill.

See Table 6.15.7.B.3: Undisturbed Area (below). <br /> TABLE 6.15.7.B.3: UNDISTURBED AREA <br /> DISTRICT UNDISTURBED AREA <br /> The area necessary to meet impervious surface <br /> requirements shall remain undisturbed during the <br /> UNIV-CA construction process. <br /> CANE-CA The area to remain undisturbed shall include portions <br /> U-ENO-CA of the lot utilized for stormwater infiltration. <br /> All clearing limits shall be clearly marked and <br /> observed. <br /> All other Watershed Overlay Districts As may be required pursuant to an approvedgrad+++g <br /> permit or erosion e +r i plan LDP. <br /> (4) Ground Cover <br /> (a) Whenever land-disturbing acti„ityLand-Disturbing Activity is undertaken <br /> on a tract comprising more than 20,000 square feet, if more than 20,000 <br /> square feet are uncovered, the person conducting the <br /> activit&and-Disturbing Activity shall install such sedimentation and <br /> erosion control devices and practices as are sufficient to retain the <br /> sediment generated by the land disturbiRg aGtivityLand-Disturbing <br /> Activity within the boundaries of the tract during construction upon and <br /> development of said tract, and shall plant or otherwise provide a <br /> permanent ground cover sufficient to restrain erosion after completion of <br /> construction or development. <br /> (b) Except as provided in Section R 1 F 7(B)(6 & 2"ef+hio rlr�e <br /> Pprovisions for a ground cover sufficient to restrain erosion must be <br /> accomplished within 15,.erkiRg days OF°n Ga!eRdaF days, Whinheyer <br /> period is sh^r+orthe timelines as specified in the most current version287 <br /> of the North Carolinas Administrative Code Title 15A Chapter 4: <br /> Sedimentation Control Fr„si n G„r,+r„i R/InIvIan,,e� Lfollowing completion of <br /> construction or development. <br /> (5) Design Storm <br /> 2"Added language regarding fill materials, in conformance with current state Model Ordinance. <br /> 28s Consistent use of"stormwater runoff". <br /> �6Teext cerrect'en—added a space. <br /> 281 For ground cover requirements-cConsistent reference to"most current version" of the NC Administrative Code <br /> Title 15A Chapter 4:Sedimentation Control. <br /> Orange County, North Carolina—Unified Development Ordinance Page 6-124 <br />
