Inundation Mapping Initiatives of the Iowa Flood Center: Statewide Coverage and Detailed Urban Flooding Analysis

The Iowa Flood Center seeks to improve Iowa’s flood hazard awareness through the development of easily accessible, high-quality flood mapping products. First, the statewide floodplain mapping project will benefit Iowans through the creation of a comprehensive set of floodplain maps developed under one consistent methodology for 85 counties in Iowa. These maps will be important tools in evaluating flood risk, regulating floodplains, and participating in the National Flood Insurance Program.

Detailed urban flood analyses are also being completed to develop inundation maps for specific Iowa communities. These maps are meant to providing a visual representation of potential flood extent in a community. The maps are based on National Weather Service predicted river forecasts at specific stream gage locations.
