Project Status

The Iowa Flood Center, in partnership with the Iowa DNR, will create draft flood hazard products for each of Iowa’s 85 counties declared Presidential Disaster Areas in 2008, with funding from the U.S. Department of Housing and Urban Development. The remaining 14 counties will be completed by the U.S. Army Corps of Engineers (USACE) with Section 22 Planning Assistance to States (PAS) funding.

The statewide mapping project will take four to six years to complete. Analyses are being performed by watershed and have been sequenced according to:

  • Supplemental funding opportunities;
  • Flood risk exposure; and
  • Opportunities to coordinate with other studies across the state.

Development of the maps follows specific guidelines that adhere to standards established by the Federal Emergency Management Agency (FEMA).


The Iowa Flood Center started work in the southwest corner of Iowa and will work towards the northeast corner of the state.
