The DNR, along with the Iowa Flood Center, FEMA 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.
These work maps can't be used for flood insurance purposes, but they will show the boundaries of flooded areas for the 1 percent annual chance (100-year) and 0.2 percent annual chance (500-year) floods. FEMA and floodplain mapping consultants hired by the DNR will develop the work maps so they can be published as Flood Insurance Rate Maps (FIRMs), which can be used for flood insurance purposes. As the work maps and FIRMs become available, individuals and local governments can use that information to better determine risks to protect their properties. |
