Ohio Rev. Code § 351.22: Eminent domain.

A convention facilities authority may acquire by appropriation pursuant to division (L) of section 351.06 of the Revised Code any public or private lands, including public parks, playgrounds, or reservations, or parts thereof or rights therein, rights-of-way, rights, franchises, easements, and interests as it finds necessary or proper for the construction or the efficient operation of any facility. In any proceedings for appropriation under this section, the procedure to be followed shall be in accordance with Chapter 163. of the Revised Code.

This section does not empower an authority to appropriate or disturb property or facilities belonging to and required for the proper and convenient operation of any public utility or any common carrier engaged in interstate commerce, unless provision is made for the restoration, relocation, or duplication of such property or facilities elsewhere at the sole cost of the authority.
