I’ve had this idea for some kind of concrete hut type of structure for those types of homeless people to use, that way it’s easily cleaned out. It would just be a way to keep them out of the rain and give them a safe spot. Maybe add a wooden bench type of platform to give them a spot off the ground. You could place them in out of the way areas, along with a bathroom/shower building. Basically an official homeless camp. Just pay homeless people as janitors to keep things tidy.
