Panhandlers and Property Rights
There's a simple solution to panhandling. Create a property right in the air space over the sidewalk and deed that property right to the adjacent business. Technically, anyone who walks through that air space is trespassing and the property owner, in this case the business, then has a legal right to tell that person to leave. The deed could grant an easement for sidewalk maintenance and law enforcement.
