Ohio Rev. Code § 4582.02: Creation of port authority.

Any municipal corporation, township, county, or any combination of a municipal corporation, municipal corporations, township, townships, county, or counties, none of which was included in a port authority in existence on December 16, 1964, may create a port authority. A municipal corporation shall act by ordinance, a township shall act by resolution of the township trustees, and a county shall act by resolution of the county commissioners, in authorizing the creation of a port authority. A port authority created pursuant to this section is a body corporate and politic that may sue and be sued, plead and be impleaded, and has the powers and jurisdiction enumerated in sections 4582.01 to 4582.20 of the Revised Code. The exercise by the port authority of the powers conferred upon it shall be considered to be essential governmental functions of this state, but no port authority is immune from liability by reason thereof.
