The City of Gretna recommends all citizens purchase flood insurance. Flooding can happen in any flood zone. Facts show individuals in Zone X areas file more than 20 percent of all flood insurance claims and receive one-third of Federal disaster assistance for flooding. Flood insurance is federally required for mortgage holders living in AE flood zone areas.

For properties moving into a higher risk area (Zone AE), the National Flood Insurance Program (NFIP)’s grandfathering rules recognize policyholders who have built in compliance with the flood map in place at the time of construction or who have maintained continuous flood insurance coverage.


 Policyholders can benefit by continuing to use their previous zone designation for their insurance rating. For properties currently in an X zone, purchasing a flood insurance policy now or maintaining flood insurance may benefit chances of grandfathering when this new map goes into effect. An insurance agent can help determine the lowest-cost option for your specific property.
