Levees, Floodwalls
and Floodgates

Without these flood protection features surrounding Greater New Orleans, communities would be inundated with storm surge.

The Network

After the levees breeched during Hurricane Katrina, people realized the vital role levees play in flood protection. The U.S. Army Corps of Engineers and the Flood Protection Authority-East have enhanced the levees, floodwalls and floodgates surrounding the Greater New Orleans area to a standard of protection from a 100-year storm with a 1% chance of occurring in any given year.

Operation & Maintenance

The Flood Protection Authority is responsible for maintaining 192 miles of levees and floodwalls, 3,530 acres of levee turf, and 244 land-based floodgates in East Jefferson, Orleans and St. Bernard Parishes.
