The French Quarter might be salvaged and enclosed in very high levees as a historical & tourist site, but IMO the rest of the city will be rebuilt, if at all, in some new location where overall rebuilding costs will be lower given both decontamination costs and the necessity of securing the site against repetitions of such flooding.
The French Quarter was lost in the 80's when I was there.
I wonder if they can use barges to close the hole in the levvee.
An excellent point about the contamination. The ramifications of this will go on for years.
Watching the videos and reading the posts, it sure makes whatever issues I'm having seem very small by comparison...
The broken levees are on the lake. There's no "upstream" contamination because the Mississippi isn't what is overflowing into New Orleans.
