The cost differential between permanent supported housing and temporary supported facilities is such that it isn’t a choice that needs to be made.
You can have both and the choice he’s trying to force doesn’t make sense. Transitional facilities as opposed to what? Driving around finding homeless people, picking them up and taking them to a permanent unit?
If homelessness is such that you’re going to have tent cities regardless, then supported tented facilities will definitely favour connection to services over illegal encampments.
