S&EC performed hydraulic analysis for the proposed Phase III Bolin Creek Greenway project to determine water surface profiles for design storms for a planned community greenway project within the Town of Chapel Hill, North Carolina. Our analyses utilized the U.S. Army Corps of Engineers (USACE), HEC-RAS (River Analysis System) to simulate existing and future developed flow conditions. Recommendations for the various proposed greenway crossing locations were prepared and integrated into the design plans. Working on behalf of the Town of Chapel Hill S&EC prepared the Flood Study report including supporting hydraulic models, floodplain and floodway mapping, water surface profiles, and a Conditional Letter of Map Revision (CLOMR) application for review by the Federal Emergency Managment Agency (FEMA). In addition S&EC performed a jurisdictional delineation of regulated wetlands and streams, and evaluated the proposed crossing in regard to USACE and NCDENR Division of Water Quality and permitting requirements.
