Ohio Rev. Code § 5553.31
Any person may, with the approval of the board of county commissioners, dedicate lands for road purposes. A definite description of the lands to be dedicated with a plat of such lands thereto attached and signed by the party dedicating such lands, with the approval and acceptance of the board indorsed thereon, shall be placed upon the proper road records of the county in which such road is situated. The board shall not approve and accept the dedication of any land for road purposes until any lien attached to such land under division (A) of section 505.82 of the Revised Code is satisfied. If the lands so dedicated contemplate a change in an existing road, the same proceedings shall be had thereon, after the board by proper resolution approves and accepts the lands for such purpose, as are provided in cases where the board by unanimous vote declares its intention to locate, establish, widen, straighten, vacate, or change the direction of a road without a petition therefor, but otherwise the proposal to dedicate lands for road purposes, together with the acceptance of the grant by the board, constitutes the lands so dedicated a public road without any further proceedings thereon.
