Shaw Environmental and Infrastructure Inc., working for the USACE, broke ground Dec. 4 on the Inner Harbor Navigation Canal Lake Borgne Surge Barrier. The $700-million surge barrier is the largest design-build civil-works project in the history of the U.S. Army Corps of Engineers. The structure is planned to stop surges from rushing up the Mississippi River and Gulf Intracoastal Waterway (GIWW) into the Industrial Canal as occurred during Hurricane Katrina. When completed in 2011, the surge barrier will extend from the Michoud Canal floodwall along the GIWW to the Mississippi River Gulf Outlet (MRGO) levee just south of the Bayou Bienvenue control structure. It will reduce the hurricane and storm surge risk faced by the people in the surrounding communities of St. Bernard, New Orleans East, Ninth Ward, and Gentilly to a 1-percent chance in any given year. Six features make up the IHNC Lake Borgne Surge Barrier Project: the GIWW north floodwall, the GIWW gates, the GIWW to Bayou Bienvenue floodwall, the Bayou Bienvenue gate, the Bayou Bienvenue to MRGO south floodwall, and the MGRO south floodwall.
