And your point is what? That the canal walls failed at below their design intent? Of all I have read about Katrina, not once have I seen that it was less than a Cat 3 when it hit NO. If the canal walls failed at less than design, then it was a disaster just waiting to happen.
Another fine example of Louisiana construction.
Look, I'm not trying to bash you or your city. But I cannot tolerate the bitching and moaning of people who have chosen to live life shaking hands with disaster everyday for decades, then when that disaster comes, they expect everyone else to fix the problem.
History is full of towns and cities that didn't recover after natural disasters. NO will survive, but it will have to be different, or suffer the same fate at some point in the future.
Anything made by man will eventually fail, if not maintained over time.If anyone cared down there, maybe more care would have been taken, and built weaknesses could have been found before failure.
Hope the higher view is better where they rebuild.
