Ohio Revised Code Title XV. Conservation of Natural Resources § 1545.22

(1) All funds under the control of a board of park commissioners shall be kept in depositories selected in the manner provided for the deposit of county funds, insofar as such proceedings are applicable, and such deposits shall be secured as provided in the case of county funds. The county treasurer of the county in which the park district is located shall be the custodian of the funds of the board and shall be an ex officio officer of the board. He shall pay the funds out upon the warrant of the county auditor of the county in which the district is located. Interest earned on all funds under the control of the board of park commissioners shall be credited to such funds.

(2) The county auditor shall be an ex officio officer of the board, and no contract of the board involving the expenditure of money shall become effective until the auditor certifies that there are funds of the board in the custody of the county treasurer and otherwise unappropriated sufficient to provide therefor. The auditor shall draw warrants on the treasurer to disburse the funds of the board upon order of the board, evidenced by the certificate of its secretary.

(3) Any such board of park commissioners may select a depository for the funds of the district, in the manner provided in sections 135.01 to 135.21 of the Revised Code, upon the adoption of a resolution declaring such intent. The resolution shall be certified to the board of county commissioners and to the treasurer in the counties in which the district is located. The board of park commissioners shall thereupon become the governing board for such district with respect to the deposit of funds of such district.
