Coler Creek Drainage Study

Because of City growth and development within the drainage basin for Coler Creek, including the Coler Mountain Bike Preserve, the City of Bentonville, Arkansas, charged Garver with performing an updated hydrologic and hydraulic study of the stream and revising the FEMA regulatory floodplain mapping and data. Garver utilized FEMA-approved modeling methodologies and the detailed lidar topography to provide the City with updated flow information along the stream reach as well as more accurate floodplain boundary mapping. The updated modeling allowed Garver to assist the City in obtaining a Letter of Map Revision (LOMR) to update the regulatory floodplain and floodway mapping. The updated modeling and mapping provided the City with better tools to understand flood risk and identify developable and non-developable areas near the creek.
