MYTH: The Orleans Levee Board used politics to force the Army Corps of Engineers to build the inadequate levee system that failed during Hurricane Katrina.
TRUTH: As revealed in the New York Times, experts J. David Rogers and Raymond Seed retracted this erroneous conclusion in their 2006 levee investigation. The levees failed mainly due to a mistake the Army Corps made in the 1980s when interpreting the results of their levee load test study.

Myth Buster Five
MYTH: A hundred thousand people in New Orleans did not evacuate even though they were warned that the levees could breach.

Myth Buster Six
MYTH: After the storm, the levee boards were “reformed” and made similar to other levee districts in the U.S.
TRUTH: New Orleans was the first urban area in the nation to create a regional board with experts. The Greater New Orleans levee system has no peer in the U.S. in terms of complexity, cost and population protected.

Myth Buster Seven
MYTH: The Orleans Levee Board ignored federal requirements to maintain the levees regularly and spent only a few hours annually inspecting them before going to lunch.
TRUTH: The widely publicized “drive-by” levee inspections pre-Katrina were actually the responsibility of the Army Corps of Engineers. These were the federal agency’s annual audit of the local levee board’s operations and maintenance (O&M) activity.

Myth Buster Eight
MYTH: Environmentalists blocked the Army Corps of Engineers’ original plan for massive peripheral barriers and forced the agency to propose a second inferior design.
TRUTH: The Army Corps decided that the High Walls Plan, or raising the heights of the levees, was less costly, less damaging to the environment and more acceptable to local interests.

Myth Buster Nine
MYTH: New Orleans doesn’t deserve to be rebuilt because of its nearly complete dependence on levees for protection.
TRUTH: New Orleans is a very important port city to the world. Furthermore, U.S. counties protected by levees are wealthier and unemployment is lower. Levees more than pay for themselves when their cost is compared to the investment they protect.

Myth Buster Number Ten
MYTH: The Army Corps of Engineers admitted fault for the failure of its levee system during Hurricane Katrina.
TRUTH: No corps official has accepted responsibility for the failure of the levees in New Orleans during Hurricane Katrina without simultaneously – and also wrongly – directing blame toward local officials and environmental groups.
