The failure of the Corps to recognize the destruction that the MRGO [Mississippi River–Gulf Outlet navigation canal] had caused and the potential hazard that it created is clearly negligent on the part of the Corps. Furthermore, the Corps not only knew, but admitted by 1988, that the MRGO threatened human life. (p. 105 )
The Corps’ lassitude and failure to fulfill its duties resulted in a catastrophic loss of human life and property in unprecedented proportions. The Corps’ negligence resulted in the wasting of millions of dollars in flood protection measures and billions of dollars in Congressional outlays to help this region recover from such a catastrophe. (p. 111)
Federal Judge Stanwood R. Duval Jr. has found that the U.S. Army Corps of Engineers’ poor maintenance of the Mississippi River–Gulf Outlet navigation canal was responsible for some of the worst flooding of St. Bernard Parish and the Lower Ninth Ward during and after Hurricane Katrina.
Mark Schleifstein of the Times-Picayune  explains : “Duval’s 156-page decision could result in the federal government paying $700,000 in damages to three people and a business in those areas, but also sets the stage for judgments worth billions of dollars against the government for damages suffered by as many as 100,000 other residents, businesses and local governments in those areas who filed claims with the corps after Katrina.”
The decision handed down in the U.S. District Court on Wednesday, November 18, is a major victory for homeowners and a breakthrough in establishing federal liability, vindicating what New Orleanians and others have been maintaining for the past four years: the worst of the catastrophe was the flooding that resulted from failures of the federally built flood protection infrastructure. But Judge Duval’s decision does not touch on the outflow canals at 17th Street, Orleans Avenue, or London Avenue; the civil action case “In re Katrina Canal Breaches” concerns only the MR-GO navigation canal.
