Together, this system of barriers, sector gates, floodwalls, floodgates and levees, also known as the Southeast LA Flood Protection Authority, provides a veritable “wall” around the Greater New Orleans area, significantly reducing the risk of flooding for more than a million residents from a 100- year* storm. The flood defense is one of the strongest and largest in the world.
*The 100-year level means reduced flood risk from a storm surge that has a 1% chance of occurring or being exceeded in any given year. [https://www.floodauthority.org/].
