Flood Zone
A flood zone is a geographic area designated by FEMA based on the level of flood risk. Properties located in high-risk flood zones are typically required to carry flood insurance as a condition of the mortgage.
Flood zones are identified on FEMA flood maps and classified by risk level — with Zone A and Zone V representing the highest risk. Properties in moderate- or low-risk zones may not require flood insurance but can still experience flooding. Flood insurance is a separate cost from your homeowners insurance.
A property's flood zone designation is not permanent. FEMA maps are periodically updated, and a property that was once outside a flood zone may be reclassified. Conversely, a Letter of Map Amendment (LOMA) can sometimes remove a property from a high-risk zone.
Why This Matters: In Louisiana, flood risk is a real and present concern. Knowing your property's flood zone before you buy — and understanding the insurance implications — prevents costly surprises after closing.
Common question
Do I need flood insurance if I am not in a flood zone?
Lenders may not require it in low-risk zones, but flooding can occur anywhere. In Louisiana, many borrowers choose flood insurance even when not required.
Can my property's flood zone change?
Yes. FEMA updates flood maps, and a property can be reclassified. A Letter of Map Amendment (LOMA) can sometimes remove a property from a high-risk zone if supported by elevation data.
