The school system retained HHR to determine the base flood elevation (BFE) for federally funded school site. We prepared hydrologic and hydraulic analysis of a Zone A flood hazard area including the impact of the school site construction on the base flood. The intent was to show compliance with NFIP regulations. Methods followed Guidelines and Specifications for Flood Hazard Mapping Partners. The hydraulic analysis included six bridges and split flows downstream of the site. We coordinated with the county, architect, and surveyor, and general engineering consultant.
