Homeless Person in Alley

[Isaac Hayes]

For the last couple of months, a homeless person has been living in the alley of a Columbus, Ohio property I own. I've been trying to fill one unit for the last two months, but nobody has signed due to this person living in the alley. I've engaged local police multiple times to help since the person has some of their things on the property, but we have not had luck getting them to permanently leave. Looks like their possessions take up a space of 5 ft x 15 ft.

Do you have any tips for permanently pushing this person away from the area of this property?
