Franklin County Hub Road Extension

S&EC performed hydraulic analyses for a proposed crossing within the Franklin County Industrial Park to determine water surface profiles for various design storms for the proposed Hub Road Extension.  Working directly for the Kerr-Tar Regional Economic Development Corporaiton, S&EC’s project scope included the development of representative U.S. Army Corps of Engineers (USACE) HEC-RAS (River Analysis System) models to accurately evaluate the proposed crossing’s effect on water surface elevation for both existing and future developed flow conditions.  S&EC’s project scope also included the preparation of the hydrologic and hydraulic report for submittal to the Federal Emergency Managment Agency (FEMA) including base flood elevations, Flood Insurance Rate Map (FIRM) revisions, the Conditional Letter of Map Revision (CLOMR) application, and necessary review coordination with 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.  Following construction S&EC will evaluate post-construction conditions and prepare the Letter of Map Revision (LOMR) application with all the necessary supporting information for FEMA review.
