Ohio Revised Code Title XV. Conservation of Natural Resources § 1545.04

At a hearing on an application for the creation of a park district, evidence may be taken as in other civil cases in the probate court, and the probate judge shall hear all arguments for and against the creation of such district. If he finds that such application is signed or authorized as provided in section 1545.02 of the Revised Code, and that the creation of such district will be conducive to the general welfare, he shall enter an order creating the district under the name specified in the application.

The judge may amend or change the limits of the territory described in the application at the time of the hearing, provided that in no case shall he increase the limits or size of said district. In case any of the original territory is eliminated from the district as finally established, the boundary lines of the district as finally ordered by the court shall not divide any existing township or municipal corporation.
