The IFC developed floodplain maps show the probability, extent, and depth of flooding for every Iowa stream draining more than one square mile. The maps are freely accessible through the Iowa Flood Information System.
In 2010, IFC researchers used laser radar (LiDAR) data provided by the IDNR that allowed them to precisely map Iowa’s river and stream network, develop computer-based flood simulations, and delineate floodplains with reasonable accuracy. The maps show the probability, extent, and depth of flooding for every Iowa stream draining more than one square mile.
Completed in 2016, these maps are a critical resource to help citizens, emergency managers, and other community decision-makers identify and communicate Iowa’s flood hazards. The maps also support informed decision-making on managing floodplain areas. Funding from the Iowa Natural Heritage Foundation allowed the team to also create maps for 2-, 5-, 10-, 25-, 50-, and 200-year floods. The floodplain maps and other information are freely accessible through a Google Maps-based web interface available at IFIS.
