Wish this guys would stop saying they are doing these sweeps for health and safety.
There is no need to continue justifying these sweeps.  These people are squatting on state, city or private property and cannot be allowed to do so.  Sweep and keep sweeping every week where ever necessary.  Stop playing whack a mole and allowing things to fester.
Do not wait until the homeless accumulate and congregate into squatter camps before you do something.  Sorry, but there really is no choice.  These people need to be pressured to enter into shelters and get right or they will continue being dysfunctional and exist on welfare and charity and there will  be more and more of them, local and outsiders.
