Article 6: Development Standards 81 <br /> Section 6.14: Stormwater Management <br /> (C) Periodic corrective action to restore dispersedff-se flow shall be taken if necessary to <br /> impede the formation of erosion gullies. <br /> 6.13.8 Land Disturbance and Planting of Vegetation <br /> (A) Area within a stream buffer which is subject to serious erosion may be disturbed for the <br /> purpose of planting and maintaining erosion-resistant vegetative cover. <br /> (B) Existing forested areas or any other healthy vegetation may not be removed from a <br /> stream buffer, except where replaced with vegetation resulting in comparable stormwater <br /> runoff velocity and quantity one year after planting. <br /> (C) New vegetation shall be planted to capture non-source pollutants before they reach the <br /> perennial stream, as per applicable Orange County Standards. <br /> Section 6.14: STORMWATER MANAGEMENT <br /> 6.14.1 Introduction <br /> As a watershed becomes more developed, the amount of impervious surface area increases, <br /> causing a decrease in the rate at which stormwater runoff which can be absorbed into the soil. <br /> This results in mere additional138 stormwater runoff139 flowing directly into streams and other <br /> water bodies. Because this additional140 direct stormwater runoff has not been filtered through <br /> the soil, pollutants from the air and land surface enter streams and increase the potential for <br /> pollution of hydrologically connected aquatic ecosystems and141 drinking water supplies. <br /> 6.14.2 Purpose <br /> It has been determined that proper management of construction-related and post-development <br /> stormwater runoff will minimize damage to public and private property and infrastructure; <br /> safeguard the public health, safety, and general welfare; and protect water and aquatic <br /> resources.142 The purpose of the Board of County Commissioners in adopting stormwater <br /> management regulations is to protect the water quality of the streams that lie within Orange <br /> County by reducing and controlling stormwater runoff and addressing nutrient reductions for both <br /> new and existing development. <br /> 6.14.3 Jurisdiction-Wide and Inter-Local Approaches <br /> (A) Orange County shall have the option of implementing jurisdiction-wide and/or inter-local <br /> approaches to control stormwater runoff and achieve nutrient reductions. <br /> (B) Any jurisdiction-wide and/or inter-local approaches must be approved by the Orange <br /> County Board of Commissioners, and the North Carolina143 Environmental Management <br /> Commission before implementation. <br /> 13s Text correction—replaced "more"with "additional". <br /> "'Consistent use of the term "stormwater runoff"—NOTE: "storm water runoff"is integrated through the <br /> remainder of Section 6.14, where applicable. <br /> 1ao Text correction—added "additional". <br /> 141 Added "hydrologically connected aquatic ecosystems"—NOTE: This is a staff recommendation to help the <br /> general public understand that Orange County is not just trying to protect human focused drinking water <br /> supplies,but also our aquatic ecosystems that are hydrologically connected. <br /> "I This language was pulled directly from the Falls Lake Model Ordinance; provides greater context in Purpose. <br /> 143 Added "North Carolina". <br /> Orange County, North Carolina—Unified Development Ordinance Page 6-97 <br />
