Corps of Engineers to close IHNC-Lake Borgne Surge Barrier sector gate and lift gate on Saturday

Published Oct. 4, 2013

What: The U.S. Army Corps of Engineers will close the Inner Harbor Navigation Canal-Lake Borgne Surge Barrier (IHNC) Gulf Intracoastal Waterway sector gate and Bayou Bienvenue lift gate due to the impacts from Tropical Storm Karen.  Upon closure of these two gates, the entire IHNC Lake Borgne Surge Barrier structure will have been operated and closed.  Once the sector gate is closed, navigation on the Gulf Intracoastal Waterway (GIWW) will be unable to pass from one side of the IHNC Surge Barrier to the other.

The IHNC Surge Barrier is a major feature of the Hurricane & Storm Damage Risk Reduction System that will reduce the risk associated with a storm surge that has a one percent chance of occurring in any given year, or a 100-year storm surge, for some of the areas hardest hit by Hurricane Katrina, including New Orleans East, metro New Orleans, Gentilly, the Ninth Ward and St. Bernard Parish. The total construction value for the IHNC-Lake Borgne Surge Barrier is an estimated $1.1 billion. The 1.8-mile long Inner Harbor Navigation Canal (IHNC)-Lake Borgne Surge Barrier, works in tandem with the Seabrook Floodgate Complex.
