N'ahleans solution?

A caller to the Hugh Hewitt show says he has invented floating house that will save people in a flood. I have suggested putting the city on pontoons, but it might be a possibility. I imagine that a lot of ideas like this will pop up in the next week or two.

Mormons are taught to store food and necessaries for such emergencies. We have some, but if I lived in New Orleans I'd have it stored in a boat ready to launch.
