Floodplain Management

A floodplain development permit must be obtained prior to the development of any property (farm or non-farm) located with Zone "A" of the Flood Insurance Rate Map for Clinton County.

Floodplain Development Permit

The Clinton County Planning and Zoning office reviews applications as they are submitted.  Applications do not require a hearing by the Planning and Zoning Commission.  Permits for areas within the Mississippi River and Wapsi River flood plains may also require approval by the Flood Plain Division of the Iowa Department of Natural Resources and the Corps of Engineers.

The Flood Insurance Rate Map (FIRM) may be viewed at the Planning and Zoning Office or are available from the FEMA Map Service Center.

  • to protect individuals from buying land unsuitable for its intended purpose due to flood potential
