You're right. We can bulldoze it in, fill the bowl with dirt from somewhere and rebuild anew on top of it. That should last until it sinks or until the sediments beneath it wash out from under the new fill.
The question is, Wouldn't it be much cheaper and much smarter to just build somehwere more sensible? I think it would be. Sinking any more funds into the future swamp called NO is just poor use of resources.
(of course if the residents want to spend their own money that's fine. Just keep your hands out of my pocket when you rebuild.)
The real issue that needs to be dealt with is the impending, and inevitable course change of the Mississippi that will bypass NO entirely anyway (cuts something like 150 miles off the rivers journey to the sea.) Now that is an issue that needs to be addressed
ok we will take our share of the oil revenues off the coast to do it. The gov is bout to block the sales of further leases until we can get those funds. I have no problem with that. As to the River. I agree with you. In fact that might have to be the hard choice we have to make here. Of course people need to be prepared that allowing the River to run its natural course will be expensive.
