Preliminary Flood Maps

FEMA is working across the nation to update the current Flood Insurance Rate Maps. Below is a list of areas where maps are currently being updated. See the maps before they become effective.

 

Property Owners Can Take Advantage of Grandfathering

If a property is mapped into a high-risk area such as Zone A or AE, and the owner has a mortgage through a federally regulated or insured lender, flood insurance will be required when the FIRM becomes effective.
