Article 6: Development Standards 107 <br /> Section 6.14: Stormwater Management <br /> (C) Periodic corrective action to restore dispersedf 4s_e 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 whiGh be absorbed into the soil. <br /> This results in more additional148 stormwater runoff149 flowing directly into streams and other <br /> water bodies. Because this additional15o 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 and151 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 Dublic health, safety, and general welfare: and protect water and aquatic <br /> resources.152 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 /> safagi <br /> �f County Commissioners in. adopting stormi.vater ma-flage.i.e.. regulations is to proted the <br /> water quality of the streams that lie within Orange County by reducing and controlling storm <br /> 6.14.26.14.3 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 /> 141 Text correction—replaced "more"with "additional". <br /> 141 Consistent use of the term "stormwater runoff—NOTE: "storm water runoff"is integrated through the <br /> remainder of Section 6.14, where applicable. <br /> 1so Text correction—added "additional". <br /> 1s1 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 /> 1sz This language was pulled directly from the Falls Lake Model Ordinance; provides greater context in Purpose. <br /> This language was pulled diFeetly fFeFn the Falls Lake Model QFdinance; pFevides gFeateF eentext an PuFpese. <br /> Orange County, North Carolina—Unified Development Ordinance Page 6-97 <br />
