Missouri Flood Zone Map
Last updated: August 2026
Missouri faces major flood risk from the Mississippi and Missouri rivers, which converge near St. Louis. The Great Flood of 1993 demonstrated the catastrophic potential of simultaneous flooding on both river systems, and flash flooding is common in the Ozarks.
4 of 115 Missouri counties are rated high or very high for inland flood risk by FEMA's National Risk Index. 12 communities participate in FEMA's Community Rating System, qualifying residents for flood insurance discounts of up to 20%.
Missouri has recorded 51,301 NFIP flood insurance claims since 1978, totaling $964.9M in payouts. See how Missouri compares in our nationwide NFIP claims data breakdown.

Levee Protection in Missouri
The USACE National Levee Database lists 14 levee systems protecting parts of 5 Missouri cities. A system's FEMA accreditation status determines how its protected area is mapped - accredited levees are typically mapped as Zone X, while non-accredited or provisionally accredited (PAL) systems generally leave their protected area in the SFHA.

Missouri Flood Zone FAQ
How do I check if my Missouri property is in a flood zone?
Enter your MO 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 Missouri?
If your Missouri 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 Missouri's flood history.
What are the most common flood zones in Missouri?
The most common FEMA flood zone designations in Missouri 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 Missouri property from a flood zone?
Yes, if your Missouri 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 Missouri'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 Missouri communities offer flood insurance discounts?
Yes, 12 Missouri 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 20% 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.
How much does flood insurance cost in Missouri?
The average NFIP flood insurance premium in Missouri is $1,417 per year across 16,815 active policies. Premiums vary by zone: Zone AE policies average $1,809/yr. Under FEMA's Risk Rating 2.0, your specific premium depends on property type, elevation relative to the Base Flood Elevation, and distance to water, not just your flood zone designation.
Which Missouri counties have the highest flood risk?
According to FEMA's National Risk Index, St. Louis, St. Charles, Jackson are among Missouri's highest-risk counties for inland flooding. Overall, 4 of 115 Missouri counties are rated "High" or "Very High" for inland flood risk. County-level ratings account for historical flood losses, social vulnerability, and community resilience.
How many NFIP flood insurance claims has Missouri had?
Missouri has recorded 51,301 NFIP flood insurance claims totaling $964.9M in payouts since 1978. The highest-claim year was 1993, with 9,045 claims and $208.5M in payouts. This history reflects cumulative flood damage to Missouri properties across decades of storm and rainfall events.
How many Missouri properties have flooded repeatedly?
Missouri has 4,485 properties with multiple flood losses. Of these, 974 are classified as Severe Repetitive Loss, meaning they have experienced four or more NFIP claims of $5,000 or more, or two or more claims where the total exceeds the building value. 378 of these properties have been mitigated.
What percentage of Missouri homes have flood insurance?
Only roughly 1 in 145 households in Missouri carries NFIP flood insurance (0.7% of estimated households). 104 counties in Missouri have elevated flood risk but low insurance coverage, indicating a significant protection gap.
Are there levees protecting Missouri cities?
Yes. The USACE National Levee Database lists 14 levee systems protecting parts of 5 Missouri cities. 5 are FEMA-accredited (generally mapped as Zone X), 4 are non-accredited (the protected area stays in the SFHA), and 1 is provisionally accredited (PAL, accreditation in progress). Levee protection is system-specific, not citywide - check a specific city's page or use the address search above for the zone at a specific property.
