West Palm started doing something like this near the waterfront. The benches had bars added so people couldn’t sleep, and there is a park where they started playing music

The bridge to go to palm beach island (which is just outside of the downtown waterfront) has 9-10 cameras. Whenever the homeless people cross the bridge, the Palm Beach police pick them up, drive them back to the mainland (West Palm) so that they’re out of their jurisdiction, and so that the island locals don’t complain
