plan that slopes exceeding the current Orange County limit of five percent (5%) <br />are necessary to facilitate safe, pedestrian friendly circulation within the <br />development and individual districts. <br />j. The developer shall ensure that all erosion control devices and designs shall <br />adhere to the Orange County Soil Erosion and Sedimentation Control Ordinance <br />dated October 23, 2007. <br />8. STORIVIWATER MANAGEMENT. The following standards shall be observed with <br />respect to stormwater management•activities for the project: <br />a. Riparian areas (stream buffers) shall be maintained in compliance with the <br />Orange County Stormwater Ordinance for Lands within the Neuse River Basin <br />(Neuse Rules) adopted March 9, 2001, and as amended October 23, 2007. <br />b. Impacts to the Neuse stream buffers on site shall comply with the uses listed in <br />the Neuse Rules and the Orange County Zoning Ordinance. Examples of listed <br />uses include utilities, roadways, etc. <br />If Neuse stream buffer mitigation is required as a result this development, <br />preference should be given to on-site mitigation such as stream buffer <br />enhancement and/or restoration. <br />c. The project shall comply with the Stormwater requirements listed in the Neuse <br />Rules. This includes: <br />i. No net increase in peak flow leaving the site from the predevelopment <br />conditions for the 1-year, 24-hour storm; predevelopment conditions are <br />those currently existing as of Apri19, 2008, and <br />ii. Nitrogen load contribution leaving the site must be held to 3.6 lbs per acre <br />per year. <br />d. A Master Stormwater Management Plan (SMP) shall be developed to address <br />stormwater runoff for the entire development even though individual parcels may <br />be responsible for installing stormwater best management practices (BMPs). <br />e. Innovative Stormwater BMPs • and .practices shall be utilized that meet or exceed <br />the requirements of the current version of the North Carolina Division of Water <br />Quality Stormwater Best Management Practices Manual (July 2007). <br />f. The Neuse Rules allow. commercial development to utilize a one time offset <br />payment to bring nitrogen down to the 3.6 lbs/ac/year if <br />g. The project shall utilize on-site stormwater best management practices (BMPs) to <br />meet these requirements to the extent practical. Using ,offset payments onl in <br />lieu of Stormwater BMP's will. not be accepted. <br />h. The project shall install Stormwater BMP's to remove enough nitrogen to bring <br />the. development down to 3.6 lbs/ac/yr export OR do a combination of BMP's and <br />offset payment to achieve a 3.6 lbs/ac/year export. A combination of Stormwater <br />BMP's and offset payment will be allowed under the following conditions: <br /> <br /> <br /> <br />18 <br />
