Ideally, housing would not be re-built below sea level for obvious
reasons...but what can be done?
-simply reinforcing and adding height to current levees...?
-maybe a backup system of aquaducts..that would be mostly dry but could
handle any overflow if original levee breaks again?
-house 'workers' distance away from workplace (high ground) but provide
highspeed rail public transportation?
-simply re-build houses, but on concrete stilts 10 feet above ground?

New Orleans as at the receiving end of a ruined eco-system.
Too many dikes and not enough drainage upstream.
100 years ago, there would have been some flooding associated with an
event like Katrina, but there would have been a higher number of
nuisance floods rather than this catastrophe we see now. Shame that
people who live upstream and who have channeled their own share of the
problem down to the folks below would ever say, "Why did those folks
down there build like that? They ought not be allowed!"
