The Iowa Statewide Floodplain Mapping Project is a collaboration between the Iowa Department of Natural Resources and the Iowa Flood Center at the University of Iowa. The partnership will lead to the creation of Iowa Draft Flood Hazard Products for the 85 counties that were declared Presidential Disaster Areas following the 2008 floods.
The Flood Hazard Products will result in maps that designate flood boundaries for the 1-percent annual chance (100-year) and 0.2-percent annual chance (500-year) flood. The maps shown on this site are provisional and are not regulatory flood maps.
