565 5.3 Will building occur in the floodway, stream, or buffer area of the proposed RTLP project site? No. No buildings or structures will be located within the floodway, stream, or buffer areas of the site. A roadway crossing,to provide connectivity,will be constructed in the floodway, stream, and buffer area. This roadway crossing has been designed as perpendicular to minimize impacts and is located at a higher point at the watershed where the stream is smaller in order to reduce impacts. Perpendicular roadway crossings of less than one third of an acre and less than 150 linear feet are considered allowable based on Neuse River Basin Riparian Buffer Rules. 5.4 Is the proposed RTLP project site located in a protected watershed? No. The RTLP project is not located within a County Watershed Protection Overlay District. The majority of the 161 acres subject to the RTLP zoning atlas amendment request are located within the Neuse River Basin and subject to applicable stormwater and nutrient reduction requirements as detailed in Section 6.15 of the Orange County Unified Development Ordinance. A small portion of the proposed project, approximately 26,000 square feet along Davis Road, is located within the Cape Fear River Basin. The proposed development will be required to adhere to applicable watershed management standards (i.e. water features buffers, prohibition on development activity,etc.) designed to address water quality issues. 5.5 What floodplain and stream protection standards will the proposed RTLP project be required to meet? For this proposed project,the following standards must be met: ■ Orange County requires 50 foot stream buffers. ■ Orange County requires 65 foot to 80 foot stream and floodplain buffers in this area depending on the slope. ■ Driveways and roadway crossings are allowed, but this requires approval from the Army Corps of Engineers and the NC Division of Water Resources. These agencies ensure that the design of the crossing will mitigate the stream/buffer impact. ■ All development shall comply with UDO Section 6.13, Stream Buffers and 6.21, Flood Regulations. 5.6 Will the proposed RTLP project have to comply with County floodplain management and floodplain buffer requirements? Yes. Based on application narrative and recommended conditions, development shall comply with all applicable floodplain management standards currently enforced within the County, including: ■ Observance of floodplain buffers in accordance with Section 6.13 of the UDO; ■ Prohibition of development/land disturbance activity within the floodplain ; ■ Fill material and grading activities are prohibited in the floodplain; ■ Utility/roadway development have to complete a 'no rise' certification package (i.e. development activities will not impact floodplain or cause an elevation in same); and ■ Prohibition on the storage of chemicals/hazardous materials within the floodplain The applicant is not seeking modification of existing development constraints associated with identified floodplain located within the project. Further staff is not recommending allowances above or beyond currently enforceable standards. RTLP project involves the preservation of approximately 41 acres (25%) of land as open space. This would include preservation of special flood hazard area (i.e. FEMA flood zones) as open space. 5.7 What erosion control and stormwater standards are being proposed for the RTLP project? The preliminary concept plan for this project proposes six permanent stormwater control measures. If the rezoning application is approved,the applicant will have to submit Erosion Control and Stormwater permit applications.These plans will have to be approved before development can begin.The 15
