Floodway/Floodplain Crossing Study

Utilizing HEC-RAS software, PMI performed a hydrologic and hydraulic study of the Ison Creek waterway. During the study, various methods of crossing the floodway were modeled to create a no-rise condition of the FEMA regulated 100-year flood elevation. The result of the HEC-RAS model was channel improvements and a bridge to cross Ison Creek without causing a rise in the 100-year flood elevation.
