Article 6: Development Standards 59 <br /> Section 6.14: Stormwater Management <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 increases, causing <br /> a decrease in the rate at which stormwater runoff which can be absorbed into the soil. This <br /> results in more additional 100 stormwater runoff 101 flowing directly into streams and other water <br /> bodies. Because this additional102 direct stormwater runoff has not been filtered through the soil, <br /> pollutants from the air and land surface may'03 enter streams and may 104 increase the potential <br /> for pollution of hydrologically connected aquatic ecosystems and 105 drinking water supplies. <br /> 6.14.2 Purpose <br /> The purpose of the Board of County Commissioners in adopting stormwater regulations is to <br /> protect the water quality of the streams that lie within Orange County by reducing and controlling <br /> stormwater runoff and addressing nutrient reductions for both 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 Environmental Management Commission <br /> before implementation. <br /> 6.14.4 General Methods <br /> The following general approaches shall be utilized to minimize the effects of stormwater pollution <br /> on hydrologically connected aquatic ecosystems106 and drinking water supplies in Orange <br /> County: <br /> (A) Non-StructuralStor-mwateF Control Measures Methods107 <br /> 100 Text correction—replaced "more"with "additional". <br /> 101 Consistent use of the term "stormwater runoff"—NOTE: "stormwater runoff"is integrated through the <br /> remainder of Section 6.14, where applicable. <br /> 10'Text correction—added "additional". <br /> 10'Text correction—added "may". <br /> 104 Text correction—added "may". <br /> 101 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 /> 106 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 /> 10I Replaced "Non-Structural Stormwater Control Measures(SCMs)"with "Non-Structural Methods"so as to avoid <br /> confusion with permanent Stormwater Control Measures(SCMs)—NOTE: "Non-Structural Methods"is integrated <br /> through the remainder of Section 6.14, where applicable. <br /> Orange County, North Carolina—Unified Development Ordinance Page 6-96 <br />
