Ohio Rev. Code Ann. § 511.241

The board of park commissioners may acquire lands for use by the township park district through an exchange of real property in which the board leases or conveys to the township all or part of the lands located within the township to which the park district holds title, in exchange for the lease or conveyance of township land from the board of township trustees to the board of park commissioners. Before any such exchange becomes effective, the county auditor shall certify in writing to the board of township trustees and the board of park commissioners that the current market value of the land that each board will receive is at least equal to the current market value of the land exchanged, plus any cash or other consideration that will be received as part of the exchange. The exchange may include terms agreed to between the board of park commissioners and the board of township trustees not otherwise prohibited by law. This section does not authorize exchanges by a board of township trustees that are otherwise prohibited by law. Section 511.25 of the Revised Code does not apply to exchanges authorized by this section.
