Article 6: Development Standa" <br /> Section 6.15:Soil Erosion and Sedimentation Contro1268F <br /> (i v) Maintain the balance of nature, <br /> (v) Prevent the obstruction of natural and artificial <br /> GlFa'Aage sdrainage ways, <br /> (vi) Inhibit flooding, and <br /> (vii) Reduce the undermining of roads and other transportation <br /> facilities. <br /> (b) Establishing procedures through which these purposes can be fulfilled. <br /> (2) It is the intent of the Board of County Commissioners that all of the departments <br /> and agencies of Orange County, its contractors and subcontractors shall comply <br /> with the regulations set forth in this Section. <br /> (B) University Lake, Cane Creek, and Upper Eno Watersheds <br /> (1) The Board of County Commissioners find that,without strict sedimentation and <br /> erosion controls, the development of land within the University Lake, Cane <br /> Creek, and Upper Eno Watersheds will have a significant adverse impact upon <br /> the health, safety, and welfare of all persons served by the water supply <br /> reservoirs within these watersheds. More specifically: <br /> (a) Stormwater runoff carries pollutants into water supply reservoirs, <br /> degrading water quality. These pollutants include, but are not limited to, <br /> organic and inorganic chemicals. <br /> (b) The increase in nutrients such as phosphorus and nitrogen will <br /> accelerate eutrophication of water supply reservoirs, adversely affecting <br /> flora and fauna. <br /> (c) The improper channelization of watercourses and drainage areas in the <br /> University Lake, Cane Creek, and Upper Eno Watersheds will increase <br /> the velocity of runoff, thereby increasing erosion and sedimentation. <br /> (d) The alteration of the natural topography and removal of vegetation will <br /> increase erosion by increasing velocity of runoff. <br /> (e) The siltation of water bodies resulting from increased erosion will <br /> decrease the capacity of the water bodies to hold and transport water, <br /> and harm flora and fauna. <br /> (f) Sedimentation further reduces water quality because it transports <br /> pollutants into the water, then releases them in the water as it settles. <br /> (g) Impervious surfaces will increase the volume and rate of stormwater <br /> runoff. This allows less water to percolate into the soil, thereby <br /> decreasing groundwater recharge. Increased velocity of runoff also <br /> reduces the filtering effect of the soil. <br /> (h) Improperly managed stormwater runoff will increase the incidence of <br /> flooding and the level of floods which occur. <br /> (2) The regulations set forth in this Section that are applicable to the University Lake, <br /> Cane Creek, and Upper Eno Watersheds are designed: <br /> (a) To protect and maintain the chemical, physical and biological quality and <br /> integrity of water supply reservoirs within these watersheds and other <br /> critical watershed areas. <br /> (b) To prevent harm to the residents of the community by prohibiting <br /> activities which adversely affect water supply reservoirs as a public water <br /> supply. <br /> Orange County, North Carolina— Unified Development Ordinance Page 6-116 <br />
