Chapter 8: Services and Facilities Element <br /> 8.4.2. EROSION CONTROL AND STORMWATER MANAGEMENT <br /> Orange County's Erosion Control Division is charged with enforcing Eounty <br /> the Erosion Control and Stormwater Ardinanees provisions of the Orange <br /> County Unified Development Ordinance, including inspections of land <br /> development, and review of erosion control plans. These provisions of the <br /> Ordinances regulate land development activities to ensure that watersheds <br /> are protected from adverse affects of development, and that grading and <br /> site development do not create hazardous stormwater flows. The division <br /> also administers the Neuse Buffer Rules and participates in regional <br /> watershed planning initiatives. <br /> The Erosion Control division reviews land disturbance activities and erosion <br /> control plans countywide, including parts of Durham County annexed by <br /> Chapel Hill. Disturbance of more than 20,000 feet in a non-protected <br /> watershed and disturbance of more than 10,000 square feet in a protected <br /> watershed must obtain pre-approval from Erosion Control and applicants are <br /> required to submit an erosion control plan. The County holds several <br /> agreements with the municipalities for enforcement, including enforcement <br /> of Hillsborough's National Pollutant Discharge Elimination System Phase II <br /> Stormwater Program and erosion control enforcement in Chapel Hill, <br /> Carrboro, Hillsborough, and the portion of Mebane in Orange County. In <br /> addition, the division develops educational materials and conducts <br /> educational programs related to erosion control, stormwater runoff <br /> pollution, stream buffers, and water quality protection. <br /> Of the 32 local governments in the Neuse River Basin, Orange County was <br /> the first and only to receive delegated authority from the state <br /> Environmental Management Commission to enforce the Neuse Rules. Any <br /> land disturbance in University Lake, Cane Creek, and the Upper Eno <br /> watersheds are reviewed by the division. Entities with the power of eminent <br /> domain, such as the Department of Transportation, University of North <br /> Carolina, OWASA, and School Districts, are regulated by the state. Orange <br /> County does monitor some of these entities through various voluntary <br /> agreements, such as a written request from the Chapel Hill-Carrboro School <br /> System to monitor Carrboro High School.
