Then why did the corp admit before congress that it was their design flaws that led to the failure of the levees?
However, the Orleans Levee Board rarely checked the walls, and when they did, really didn't do anything other than check off the walls were there.
From Wikipedia:
“Investigations after the disaster revealed that the levee and flood wall system was apparently mis-designed by the Army Corps of Engineers, and that the inspections by the board were perfunctory at best.”
“In the aftermath of the flooding, there have been calls for the elimination of the Orleans Levee Board and other local and regional boards. During a special session of the Louisiana Legislature, a bill was passed into law by Sen. Walter Boasso (D-Arabi), which consolidated the levee boards of various parishes between New Orleans and Baton Rouge.”
“The Orleans Levee Board ceased to exist on January 1, 2007.”
