probably a few years. They aren't letting people just gather all the rubble and ship it off.. it has to be gone through, seperated, etc.
When we were clearing rubble, we were told to make 4 piles. Of course, this all pretty much needs to be done by hand.
Trees/Tree Limbs - chipped
Lumber (wood with nails, etc) - probably burned
Metal - scrapped
Trash/Other Debris - sent to garbage
