I think that this is a good time to get with the Dutch and engineer dikes and levees that will protect the future city. They should keep everybody evacuated, take what land they need and re-do the whole place.
They also need to do something about the loss of the marshlands between New Orleans and the Gulf.
I used to live in Gulf Springs by Biloxi and there isn't much you can do to protect that part of the Gulf from a Catagory 5.
