Ohio Rev. Code § 5120.46: Appropriating property.

When it is necessary for a state correctional institution to acquire any real estate, right-of-way, or easement in real estate in order to accomplish the purposes for which it was organized or is being conducted, and the department of rehabilitation and correction is unable to agree with the owner of the property upon the price to be paid therefor, the property may be appropriated in the manner provided for the appropriation of property for other state purposes.

Any instrument by which real property is acquired pursuant to this section shall identify the agency of the state that has the use and benefit of the real property as specified in section 5301.012 of the Revised Code.
