CMP appx. 60' in length on SR-1324 was blown out during Hurricane Florence. Emergency 84in. CMP of appx. 48 ft. in length and Roadway fill was installed to establish temporary service. Emergency 84in. CMP is undersized and will not support high conveyance during major flood events. The proposed culvert is a 2@10'x7' RCBC with bevels, 51 ft. in length, buried 1ft. with sills and filled with native material. Upstream invert 234.52ft. and downstream invert 234.52ft, slope 0.0%. Roadway drainage runs off on either side of the proposed roadway and disperses into wetlands and/or natural ground. Construction of the new culvert will take place while an off-site detour maintains traffic. Bank Stabilization rip rap will be installed as necessary to prevent streambank degradation. 1011 Schaub DrNorth Carolina Department of TransportationHighway Stormwater Program STORMWATER MANAGEMENT PLAN FOR NCDOT PROJECTSProject Type:121 DOT DriveAddress:General Project InformationWBS Element:OtherWBS Element:MI Engineering, PLLC NCDOT Contact:[phone]Suite 100Raleigh, NC 27606Contractor / Designer:(919) [e-mail]:ScotlandSilver HillTim Welch, PECarthage, NC 28327River Basin(s): City/Town:0.3Typical Cross Section Description: Surrounding Land Use: General Project Narrative:(Description of Minimization of Water Quality Impacts)NoWoodsJuniper Creek Upper14-34-4-30.20.095 mi.Project DescriptionProposed ProjectLumberNoneSupplemental Classification: Swamp Waters (Sw) Wetlands within Project Limits?
