Nope, they should not attempt to rebuild New Orleans as it was. Make it back into the port town that it historically was, but move most of the residential and tourism stuff away and to higher ground (where it should be).
That's what I was thinking, but didn't know how people might take it.
The old town and the working port can be saved and should be IMHO... but a conurbation of that size which is likely to be swept away again within the next ten years or so... its just not sensible IMHO and it would probably be best to move the residential areas inland onto higher ground… perhaps even as far a field as Baton Rouge way.
You realize that all the tourism stuff is down in the Quarter?
