Ohio Rev. Code Ann. § 3.112

An elected officer or an employee of a county, township, or municipal corporation may simultaneously serve as a member or officer of the board of trustees of a transportation improvement district created under Chapter 5540. of the Revised Code. Neither the simultaneous holding of the two positions nor the financial or contractual relationship between a county, township, or municipal corporation and the transportation improvement district shall constitute the holding of incompatible offices or employment and are permissible, notwithstanding Ohio common law or any contrary provision of the Revised Code. An elected officer or an employee of a county, township, or municipal corporation who serves simultaneously as a member or officer of the board of trustees of a transportation improvement district does not have an unlawful interest in a public contract under section 2921.42 of the Revised Code by virtue of a financial or contractual relationship between the county, township, or municipal corporation and the transportation improvement district.
