In addition to debris removal, general clean-up, and repairing the infrastructure, an even bigger issue for the St. Maarten gov't will be dealing with the newly homeless population. What will they do - erect barrack style housing or set up refugee style camps? It all takes time and money.
Another problem will be unemployment. Obviously, a lot of people will no longer have jobs or incomes? What provisions will the gov't make for that?
Finally, there could be a vermin infestation (and in this case I'm not talking about the human vermin marauders).
This is going to be a big, big job. I hope they're up to it.
