Work on IHNC began recently as a significant part of the city’s hurricane and storm drainage risk reduction system (HSDRRS). When completed in 2011, the $700M barrier will act as a key element in the defence against storm surges for Greater New Orleans’ most vulnerable areas, reducing the risk faced by the surrounding communities of St. Bernard, New Orleans East, Ninth Ward and Gentilly to a 1% chance in any given year.
