The Iowa Department of Natural Resources (DNR) regulates construction on all flood plains and floodways in the state to protect life and property; and to promote the orderly development and wise use of Iowa's flood plains.
Any person who desires to construct or maintain a structure, dam, obstruction, deposit or excavation, or allow the same in any flood plain or floodway must contact the Iowa DNR Prior to the beginning of any work. The Iowa DNR will help determine if the proposed project needs an approved flood plain development permit.
