Flood Risk in Louisiana

Louisiana's low elevation and proximity to the Gulf of Mexico make it one of the most flood-prone states. New Orleans sits largely below sea level, protected by an extensive levee system rebuilt after Hurricane Katrina.

Understanding Louisiana Flood Zones

FEMA designates flood zones across Louisiana using the following classifications:

AE High Risk — 1% annual chance of flooding (100-year floodplain). Insurance required for federal mortgages.

VE Very High Risk — Coastal flooding with wave action. Strictest building codes.

X (Shaded) Moderate Risk — 500-year floodplain. Insurance recommended.

X Low Risk — Outside major floodplains. Insurance optional but advisable — 20%+ of NFIP claims come from low-risk zones.

Flood Insurance in Louisiana

Properties in Louisiana FEMA-designated Special Flood Hazard Areas (zones A and V) with federally backed mortgages are required to carry flood insurance through the National Flood Insurance Program (NFIP).

Even outside high-risk zones, flood insurance is recommended. NFIP claims data shows that over 20% of claims nationwide come from low and moderate-risk areas. Louisiana residents can purchase flood insurance through the NFIP or private insurers.
