What Your Flood Zone Means in Houma
Houma is primarily at risk from coastal flooding, including hurricane storm surge, tidal flooding, and wave action. Coastal storms can push seawater inland with little warning, and properties in VE (Velocity) zones face the most severe exposure to breaking waves. The most common FEMA flood zone designations in Houma are Zone AE, Zone VE, Zone X. FEMA's National Risk Index estimates the county's annual expected loss from inland flooding at over $19.9M. Properties in Houma's VE zones face additional wave action risk beyond still-water flooding, which typically results in higher insurance premiums and stricter building requirements.
Coastal flood insurance premiums in Houma are typically higher than inland areas due to the destructive force of storm surge and wave action. Properties in VE zones face the highest premiums because wave damage compounds the risk beyond still-water flooding. If your property is in a Special Flood Hazard Area (SFHA) and you have a federally regulated or government-backed mortgage, federal law generally requires your lender to ensure you carry flood insurance.
Coastal flood maps are among the most frequently updated in the FEMA system, as shoreline erosion and new storm surge modeling refine the boundaries. Letters of Map Revision (LOMR) may shift VE and AE zone boundaries after major storms or updated coastal studies. Use our free lookup tool to check the current flood zone for any Houma address.

Can my Houma property be removed from a high-risk flood zone?
Yes, if your property's natural ground elevation is above the Base Flood Elevation and FEMA inadvertently mapped it in a high-risk zone, you can apply for a Letter of Map Amendment (LOMA). A successful LOMA removes the property from the Special Flood Hazard Area, generally eliminating the federal mandatory flood insurance requirement. You will need an elevation certificate from a licensed surveyor. If a property was raised above the BFE with fill material, the process is a LOMR-F rather than a LOMA.
What is Base Flood Elevation in Houma?
Base Flood Elevation (BFE) is the predicted height of floodwaters during a 1% annual chance (100-year) flood, shown on FEMA maps as an elevation number in feet above sea level. In Houma's Zone AE and Zone VE areas, BFE lines appear on the FIRM as wavy contours labeled with elevation values. Properties with a lowest floor at or above the BFE typically qualify for significantly lower NFIP flood insurance premiums.
