NEW ORLEANS - MAY 12: A Virgin Mary statue is all that remains of a flooded home in the Lower Ninth Ward May 12, 2009 in New Orleans, Louisiana. A lawsuit in federal court in New Orleans pits five individuals and one business against the U.S. Army Corps of Engineers, claiming that a nagivation channel in the Mississippi River at the Gulf of Mexico outlet served as a funnel for the Hurricane Katrina storm surge in 2005 that overwhelmed the city levy system.
