This floodgate structure adjoins miles of levees and floodwalls to protect vulnerable areas in St. Bernard Parish from storm surge.
In St Bernard Parish
After Hurricane Katrina, the U.S. Army Corps of Engineers constructed a complex of control structures at Caernarvon in St. Bernard Parish. The new Caernarvon Sector Gate includes a 56 foot-wide navigable sector gate at a height of 26 feet above sea level. The adjoining floodwalls are intersected by land based floodgates across Highway 39 and the Norfolk Southern Railroad tracks. It ties the 23 miles of new floodwalls in St. Bernard Parish to the Mississippi River Levee at the southeast end of the Hurricane and Storm Damage Risk Reduction System (HSDRRS).
Operation & Maintenance
Once construction was completed in 2011, the Corps transferred responsibility of operation and maintenance to the Flood Protection Authority-East.
