More Than 6,000 Parcels In Jefferson Parish Get Improved Flood Elevations

Good News For Jefferson Parish Flood Insurance Rates

JEFFERSON  – The final flood maps for Jefferson Parish have been approved at the federal level, and more than 6,000 parcels have been marked as being in less risk for flooding, creating the potential for flood insurance savings when based on risk.

Jefferson Parish Flood Insurance rates have used the same maps for the past 22 years. These newly-finalized maps from the Federal Emergency Management Agency (FEMA) for this year were based on ground elevation, upgrades to drainage canals and pump stations and an improved levee system.

The maps went into effect for flood insurance rates starting February 2.

Drainage projects currently underway will benefit impacted areas. Parish staff is working with FEMA to amend the maps once the improvement projects are complete, potentially lowering flood insurance rates further.

The following is a comparison from the 1995 and 2018 maps:

• More than 60,000 parcels decreased in the base flood elevation.

“FEMA’s approval of these Flood Insurance Rate Maps should benefit thousands of our residents save money on their flood insurance premiums. I encourage all citizens to maintain flood insurance to protect your property from an unexpected flood event,” said Jefferson Parish President Mike Yenni.

Although an improvement in flood risk, parish officials recommend that all residents carry flood insurance.

Facts show individuals in Zone X 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 Zone AE areas. An insurance agent can help determine the lowest-cost option for specific properties.
