Floodplain Zoning and Management Resources

Model Zoning Ordinance

A new standard model floodplain ordinance went into effect on April 8, 2022. This model should be used by any community amending or adopting a floodplain ordinance after that date.

For copies of the documents listed below in Microsoft Word format or for copies of earlier versions of the model ordinances, please contact DNR Floodplains.

Model Zoning Process and Checklist

A step-by-step guide [PDF] is available to help describe the process to adopt a floodplain zoning ordinance. A timetable [PDF] is also available to illustrate the timeline and process for ordinance adoptions relation to Letter of Final Determinations (LFDs).

The floodplain ordinance checklist is available to help zoning administrators ensure that their specific ordinances aligns with the floodplain model ordinance. An editable Microsoft Word format is available upon request, please contact DNRFloodplains. We ask administrators to provide this checklist to DNR staff whenever ordinance reviews are needed to help streamline the review process.
