Myth busters

Keep these facts at your fingertips. Myths and wrong information are still out there. You can help quell them.

“Public perception of levee failures and ongoing risk is largely based on falsehoods. We have done the fact-checking and are proud to present these truths.” H.J. Bosworth Jr., P.E., civil engineer and Levees.org lead researcher

MYTHHurricane Katrina flooded New Orleans.

TRUTHThe levees and floodwalls designed and built by the U.S. Army Corps of Engineers broke in about 50 places. Many failed with water well below their tops. The American Society of Civil Engineers concluded the majority of the flooding was due to the levees failing.

MYTHThe Orleans Levee Board forced the Army Corps of Engineers to build the inadequate levee system that failed during Hurricane Katrina.

TRUTHAs reported in the New York Times, experts J. David Rogers and Raymond Seed retracted this erroneous conclusion from their 2006 levee investigation. The levees failed mainly due to a mistake the Army Corps made in the 1980s when interpreting the results of its own load test.

MYTHThe Orleans Levee Board spent only a few hours annually inspecting the levees before going to lunch.

TRUTHThe Army Corps of Engineers spent only a few hours annually inspecting the levee districts' maintenance before going to lunch. From 1959 to 2004 the Orleans Levee District was graded “Outstanding,” and no visual inspection could have found design flaws deep underground.

MYTHEnvironmentalists blocked the Army Corps' original plan for massive barriers and forced the agency to build an inferior design.

TRUTHA court required the Corps to write more than a four-page environmental impact statement. The Corps never did. Its own 1980 analysis concluded that higher levees were less costly, less damaging to the environment and more acceptable to local interests.

MYTHThe Army Corps of Engineers admitted fault for the failure of its levee system.

TRUTHNo Corps official accepted responsibility for the failure of the levees without simultaneously — and wrongly — directing blame toward local officials and environmental groups. In 2012, the Corps' former commander admitted he had no data to back up those claims.

MYTHAs Katrina advanced, residents of New Orleans were warned the levees could breach.

TRUTHEven the most desperate appeals from local, state or federal officials did not warn that the levees could breach and fail. The first suggestion came at 1:47 a.m. in a memo to the White House Situation Room, six hours after the evacuation was completed.

MYTHThe local levee districts must be guilty of negligent maintenance, because they settled.

TRUTHJudge Stanwood Duval's 2009 settlement in the class action lawsuit against the pre-Katrina levee districts is neither proof of culpability nor acceptance of responsibility. The money came from insurers protecting themselves from bad-faith claims. It's a settlement, and nothing more.

MYTHLocal politicians stole the federal levee money.

TRUTHContracts for both the design and construction of the hurricane protection belonged to the U.S. Army Corps of Engineers, as mandated by the Flood Control Act of 1965. Federal, state and parish investigations of levee corruption were closed with no indictments.

MYTHAfter the storm, the levee boards were “reformed” to be like other levee districts in the U.S.

TRUTHNew Orleans was the first urban area in the nation to create a regional levee board with experts. Louisiana had to write the law from scratch, because no model existed. California soon followed.

MYTHCongress gave New Orleans $110 billion. Isn't that enough?

TRUTHFederal allocations covered three hurricanes (Katrina, Rita and Wilma) across five Gulf states. The bulk of early funds went to emergency housing, aid and cleanup, and almost $20 billion was flood insurance payouts on policies people had paid for.
