LMRK was tasked to perform a full-scale hydrological and hydraulic (H&H) analysis and provide options for a bridge over Cherry Creek located on the north boundary of the Automax Hyundai Property in Del City, Oklahoma.  The study was performed to address the need for obtaining a Letter of Map Revision (LOMR) form the Federal Emergency Management Agency (FEMA) and get approval from local an

d state regulatory agencies. 

 Effective, corrected effective, existing, and proposed hydraulic models were developed to satisfy FEMA requirements and bridge sizes for span bridge, reinforced concrete box (RCB), and a prefabricated bridge were submitted for the client review and use.  The recommended bridges were designed to preserve the water surface elevations throughout the reach and eliminate the need for a regulatory map change.
