Note - Below are flood storage maps for Door County, Wisconsin. The Effective date of these products is May 8, 2024. Your floodplain ordinance must be adopted and approved by the DNR and FEMA by this date for your community to remain in good standing in the NFIP. Communities should have DNR staff review the draft local floodplain ordinance well before the ordinance is presented to the local governing body for adoption in order to ensure compliance with the NFIP and Chapter NR 116, Wis.

DNR staff are prepared to assist with the ordinance review and adoption process and explain state and federal regulatory requirements.
