Dam SafetyThe Iowa DNR is responsible for the state's dam safety program. DNR staff review and approve the construction of new dams, maintain an inventory of existing dams that meet minimum size criteria and periodically inspect certain dams. Currently there are approximately 4,100 dams on the state's dam inventory.
Flood Plain Development RegulationsIowa Administrative Code contains several chapters that regulate development in Iowa's flood plains. The regulations contain the minimum standards for projects located in Iowa's flood plains must meet.
National Flood Insurance ProgramThe DNR works with communities and counties to develop and administer local floodplain management programs, coordinates the National Flood Insurance Program, and assists the Federal Emergency Management Agency and the Iowa Emergency Management Division in responding to flood disasters.
The Iowa Department of Natural Resources regulates construction on all floodplains and floodways in the state to protect life and property; and to promote the orderly development and wise use of Iowa's floodplains. If you have questions about anything in the DNR Floodplain and Dam Safety Section, please contact our Helpline at 866-849-0321 or firstname.lastname@example.org.
Floodplain MappingThe 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.
