TRUDAT.  You really need enforcement, which is non-existent. NOW, they're planning on training a crew to police public areas (after years of neglect and area cleanups). IMHO, the homeless sleeping on sidewalks, bus stops, etc. would move if just told to do so. I've suggested the military expertise
 be involved in campsite setups as they are experts in temporary living quarters. With our limited $$ resources, we don't need aesthetics as much as basic, bare-bones necessities, tents for individuals, couples and family sized living quarters (all tents). latrines and showers, camp rules and SECURITY for enforcement.
