What's Happening in Brown County
FEMA's Great Lakes Coastal Flood Study has led to significant changes in Brown County's flood maps. The updated maps reflect new coastal flood modeling along the Green Bay shoreline and Fox River corridor. Homes near the bay, the Fox River mouth, and low-lying areas of the Green Bay metro now fall within expanded AE and new VE zones.
- Zone VE (Coastal High-Hazard): Areas subject to wave action of 3 feet or more during a base flood event. This is the highest-risk coastal zone.
- Zone AE (High-Risk): Areas with a 1% annual chance of flooding where base flood elevations have been determined.
- Zone X (Low-to-Moderate Risk): Areas outside the 1% annual chance floodplain. Flood insurance is not required but is still recommended.
The Green Bay metro area, including shoreline properties along the bay and the mouth of the Fox River, saw significant flood zone changes. Neighborhoods in Green Bay, De Pere, and Allouez near the bay and river corridors are most affected.
What the FEMA Letter Looks Like
Letter of Final Determination (LFD)
FEMA issued a Letter of Final Determination on September 17, 2025, addressed to Brown County community officials. This letter confirmed that new flood maps would take effect on March 17, 2026. You may have received a separate notification from your county or municipality about the map changes.
Your mortgage lender will review your property's updated flood zone status. If your property moved into a high-risk zone (AE or VE), your lender will send you a notice requiring flood insurance — typically giving you 45 days to obtain coverage. If you don't obtain coverage, the lender may force-place flood insurance at a significantly higher cost.
