The clean-up is going to be enormous... I imagine that whole sections of the city wil need to be pumped out (a time consuming and difficult process) dried-out for a few weeks to allow in heavy equipment, and then completely bulldozed.

The sad reality is...This was bound to happen sooner or later. And for those who rebuild there it will eventually happen again: The entire area is slowly sinking further and further below sea level as it is no longer refreshed with Mississippi River sediment.

If they rebuild, they need to build everything on stilts. Maybe make it into a Venice-like canal city...

Hundereds of thousands of people have been completely displaced by this storm. Everybody needs to pitch in and help...give whatever you can give.
