Minnesota Flood Zone FAQ
How do I check if my Minnesota property is in a flood zone?
Enter your MN address in FludZone's free lookup tool. We query FEMA's National Flood Hazard Layer in real-time to show your flood zone designation, whether flood insurance is required, and your property's risk level.
Do I need flood insurance in Minnesota?
If your Minnesota property is in a Special Flood Hazard Area (SFHA), meaning zones starting with A or V, and you have a federally regulated or government-backed mortgage, federal law generally requires your lender to ensure you carry flood insurance. Properties in Zone X are not subject to the federal mandate but lenders may still require coverage, and it is often recommended given Minnesota's flood history.
What are the most common flood zones in Minnesota?
The most common FEMA flood zone designations in Minnesota are Zone AE, Zone A, Zone X. Each zone reflects a different level of flood risk, from high-risk areas where flood insurance is generally required for federally regulated or government-backed mortgages to lower-risk areas where coverage is optional but recommended.
Can I remove my Minnesota property from a flood zone?
Yes, if your Minnesota property's natural ground elevation was always above the Base Flood Elevation and FEMA inadvertently mapped it in the SFHA, you can apply for a Letter of Map Amendment (LOMA) through FEMA. For properties in Minnesota's AE and A zones, the LOMA process is relatively straightforward when the elevation data supports it. If your property was raised above the BFE with fill, the process is a LOMR-F. A successful LOMA generally removes the federal mandatory flood insurance requirement, but your lender may still choose to require coverage. You'll need an elevation certificate from a licensed surveyor.
Do any Minnesota communities offer flood insurance discounts?
Yes, 7 Minnesota communities participate in FEMA's Community Rating System (CRS), a voluntary program that rewards communities for exceeding minimum flood mitigation standards. Residents in participating communities can receive NFIP premium discounts of up to 25% in the Special Flood Hazard Area. Properties outside the SFHA also benefit: CRS classes 1 through 6 receive a 10% discount, and classes 7 through 9 receive a 5% discount on NFIP premiums. Check your city's page on FludZone to see if your community participates.
