<br />stormwater management activities for the project: <br />a. Riparian areas (stream buffers) shall be maintained consistent with the provision(s) of <br />Section 6.13 of the UDO. <br />b. Impacts to the Neuse stream buffers on site shall comply with the uses listed in the <br />Neuse Rules and the Orange County Unified Development Ordinance. Examples of <br />listed uses include utilities, roadways, etc. <br />c. The project shall comply with the stormwater requirements listed in the Falls Lake <br />Rules. This includes: <br /> <br />i. No net increase in peak flow leaving the site from the predevelopment conditions <br />for the 1-year, 24-hour storm; <br />ii. Nitrogen and Phosphorus load contributions leaving the site must be held to 2.2 <br />lbs per acre per year and .33 lbs per acre per year respectively. These standards <br />can be met via offset payments and/or SCMs. <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 be <br />responsible for installing stormwater control measures (SCMs). <br /> <br />e. Innovative stormwater SCMs and practices may be utilized that meet or exceed the <br />requirements of the current version of the North Carolina Division of Water Quality <br />Stormwater Best Management Practices Manual (Latest Edition). <br />f. The developer shall collaborate with County staff during the SMP design process. <br /> <br />9. WATER SUPPLY AND SEWAGE DISPOSAL. Please refer to Section Four (4) Utilities and <br />Other Public Services. <br /> <br /> <br />SECTION 2-2-3 GENERAL PERFORMANCE STANDARDS <br />1. ENVIRONMENTAL: <br /> <br />The improvements common to the development of each building pod result in a relatively <br />limited overall land disturbance as compared to the developed area. Further, with the <br />exception of a single road crossing, there are no impacts to the 100-year floodplain or Neuse <br />River buffers and substantial open space is preserved and maintained. The development <br />also utilizes an existing stream crossing on the I-40 service road for access. Minor impacts <br />will result from the new internal road crossing necessary to provide connectivity between <br />the four proposed development areas/pods. The crossing has been designed as a <br />perpendicular crossing to minimize impacts and is located higher in the watershed where <br />the stream is smaller to further reduce impact. Additionally, onsite stormwater runoff <br />generated by the development of the site is being attenuated and treated via SCMs to <br />minimize downstream impacts. <br /> <br />The following additional performance standards shall be adhered to in addressing the <br />environmental impact of the RTLP project: <br />48
