Floodplain Mapping The DNR, along with the Iowa Flood Center and other partners, is creating new, comprehensive, accurate floodplain maps for Iowa cities and counties. Starting in 2011, many Iowans will know if their property is at risk from flooding for the first time, as many Iowa communities have never had accurate floodplain maps.
