If you're a planner in a city or county with a high homeless population, what are some of the ways that you tackle the problem? Do you consider the problem to be something that the planning department should concern itself with at all? Is zoning for shelters all that you can do? Do you even want to zone for more shelters? Do any of you rely heavily on local policy changes to reduce or move homeless populations?

Thanks a bunch ahead of time for the input.
