Ohio Rev. Code § 755.43
When real estate that has been dedicated to or for the use of the public for parks or park lands is vacated by the legislative authority of a municipal corporation pursuant to section 755.41 of the Revised Code, and where reversionary interests have been set up in the event of the non-use of such lands for the dedicated purpose, such reversionary interests shall accelerate and vest in the holders thereof upon such vacation. Thereupon, the auditor of the county shall place the lands on the tax duplicate of the county in the names of such reversionaries as are known to and supplied by the legislative authority of the municipal corporation or the board or officer having supervision or management of such real estate. If the legislative authority of such board or officer is unable to furnish the names of such reversioners, the legislative authority of a municipal corporation shall fix a date on or before which claims to such real estate may be asserted and after which such real estate shall be sold. Notice shall be given of such date and of the sale to be held thereafter, as provided in section 7.16 of the Revised Code or once each week for four consecutive weeks in a newspaper of general circulation in the municipal corporation wherein such lands are located. In the event that no claims to such lands are asserted or found to be valid, the lands shall be sold pursuant to section 755.42 of the Revised Code, and the title of any holders of reversionary interests shall be extinguished.
Nothing contained in sections 755.41, 755.42, or 755.43 of the Revised Code shall be construed as limiting any of the home rule powers conferred upon municipalities by Article XVIII of the Constitution of the State of Ohio.
