The DNR Floodplain Management Program has developed a variety of sample ordinances for use by communities. The ordinance your community should use will depend on the type of maps prepared by the Federal Emergency Management Agency (FEMA) for your community, the types of flood zones shown on those maps, and the level of development that exists or could occur in floodplain areas.
We recommend that you contact DNR Eco-Waters Floodplain Program staff for assistance prior to adopting a floodplain ordinance. Each community is unique, and the generic ordinances included here should be tailored to each community. Also note that the DNR must approve new floodplain ordinances prior to their adoption in order to verify that minimum state and federal standards are met and ensure community eligibility for the National Flood Insurance Program.
This comprehensive ordinance includes three types of floodplain zones: (a) floodway, (b) flood fringe and (c) A Zones ("general floodplain"), identified as separate districts in the ordinance. It can be adapted to a variety of situations. Floodplain Program staff can assist communities in determine how to tailor this ordinance to meet their needs.
Use this sample ordinance if your community has a FEMA flood risk map, but has limited existing and potential development within the mapped floodplain.
Use this sample ordinance if your community does not have a FEMA flood risk map, or if there are no flood risk areas within your boundaries on a countywide FEMA Flood Insurance Rate Map.
