FEMA has updated the flood maps for Lake County, Illinois. Here's what it means for your home and your mortgage.

⚠ Important: New Flood Maps Take Effect July 21, 2026

New FEMA flood maps for Lake County take effect on July 21, 2026. If your property is now in a high-risk flood zone (Zone AE or VE), your mortgage lender will require flood insurance. You may have already received — or will soon receive — a letter from your lender.

What's Happening in Lake County

FEMA has updated Lake County's flood maps based on new coastal flood studies along the Lake Michigan shoreline. The changes expand flood zones where wave action, storm surge, and high lake levels pose risks to homes along the North Shore communities.

Properties along the Lake Michigan shore — including Waukegan, Highland Park, Lake Forest, Lake Bluff, and the North Shore communities — are most affected by the new maps.

What the FEMA Letter Looks Like

Letter of Final Determination (LFD)

FEMA issued a Letter of Final Determination in January 2026, addressed to Lake County community officials. This letter confirmed that new flood maps will take effect on July 21, 2026. You may have received a separate notification from your 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 act, the lender may force-place flood insurance at a significantly higher cost.
