"Team Louisiana", the state-sponsored "forensic levee investigation team" with "six LSU professors and three independent engineers" says the floodwall on the 17th street canal was bound to fail due to improper design that didn't take into account weak soils below the levee.
And, they say that bad design should have been obvious to those responsible: the Army Corps of Engineers, Eustis Engineering (a local company) and Modjeski and Masters (national company).
That miscalculation was so obvious and fundamental, investigators said, they "could not fathom" how the design team of engineers from the corps, could have missed what is being termed the costliest engineering mistake in American history.
..."It's simply beyond me," said Billy Prochaska, a consulting engineer in the forensic group known as . "This wasn't a complicated problem. This is something the corps, Eustis, and Modjeski and Masters do all the time. Yet everyone missed it -- everyone from the local offices all the way up to Washington."
