Most western cities doesn't have these kind of areas as there simply aren't homeless people enough to live there. With a working social security net it wouldn't need to be accounted for in the planning at all.
No disagreement at all, but given the choice of sticking it out and doing needle sweeps of the playground before letting my kid play, or moving to a city that doesn't have that problem, guess which one was the easy decision?
In other words, don't conflate my lack of desire to spend another year dealing with homeless people as a lack of desire to find real solutions to homelessness. It's a 20 year problem, my kids will be grown up before it's not an issue anymore.
