train, truck, shipping container--all sound like good ideas. At least that would never be in one place long enough to permanently reduce property values.
I guess my original question (where are they gonna put these things?) goes unanswered...there is no zone to my knowledge that allows the placement of these things.
Now, they could put them on wheels and call them mobilhomes, but then they'd have to go in a park that is developed to the same level that any other mobile park is, and that would entail 'space rent'. But if you have no job/income you got no money for rent, which is why you are homeless in the first place.
That's why I found it interesting when the Exec. Director told me she didn't know where they would place the containers--she kept going back to the fact that they would be putting the homeless to work making the conversions.
