Article 6: Development Standards 117 <br /> Section 6.15: Soil Erosion and Sedimentation Contro1245F <br /> (2) If conditions (a) or(b) of this Subsection above cannot be met, then the receiving <br /> watercourse, to and including the discharge point, shall be designed and <br /> constructed to withstand the expected velocity anywhere the velocity exceeds the <br /> "prior to development"velocity by 10%. <br /> (C) Standards <br /> (1) Intent <br /> Stream banks and channels downstream from any land--disturbing activity shall <br /> be protected from increased degradation by accelerated erosion caused by <br /> increased velocity of stormwater runoff from the land--disturbing activity. <br /> (2) Acceptable Management Measures <br /> (a) Measures applied alone or in combination to satisfy the intent of this <br /> Subsection are acceptable if there are no objectionable secondary <br /> consequences. <br /> (b) Innovative techniques and ideas will be considered and may be used <br /> when shown to have the potential to produce successful results. Some <br /> alternatives are to: <br /> (i) Avoid increases in suF#ase stormwater runoff volume and velocity <br /> by including measures to promote Infiltration to compensate for <br /> increased stormwater runoff from areas rendered impervious; <br /> (ii) Avoid increases in stormwater discharge runoff velocities by <br /> using vegetated or roughened swales and waterways in lieu of <br /> closed drains and high velocity paved sections; <br /> (iii) Provide energy dissipaters at outlets of storm drainage facilities <br /> to reduce stormwater runoff velocities to the point of <br /> discharge; these may range from simple rip-rapped sections to <br /> complex structures; and <br /> (iv) Protect watercourses subject to accelerated erosion by <br /> improving cross sections and/or providing erosion-resistant <br /> lining. <br /> Orange County, North Carolina—Unified Development Ordinance Page 6-134 <br />
