"The Army Corps of Engineers acknowledged Thursday that design defects in the levees protecting New Orleans caused the majority of flooding during Hurricane Katrina and that the disaster would almost certainly trigger reforms in how the federal government protected the American public....

The corps released a 6,000-page report written in the couched language of government engineers but which delivered a stunning set of findings about errors made in the design of storm walls and earthen levees that failed during Katrina.

The report found that four major breaches of I-walls, a type of concrete storm wall that sits on an earthen levee, caused 65% of the flooding in the New Orleans area."
