How will the cities be rebuilt?

In the rebuilding of the Gulf Coast cities, how will that be done? Will the cities be rebuilt as they were, or is this the opportunity to start with a "clean slate", and create places that, as Mark Trahant says in this piece, are places where everybody wants to come?

Only time will tell, of course, but my hope is that both the citizens of the region, and the local, state and federal government officials will sit down and seriously consider exactly what should be done, and how they will go about it. Only a serious discussion will enable them to avoid the mistakes of the past.
