Ohio Rev. Code § 4951.07
When a grant is made by the legislative authority of a municipal corporation, either for a new route or as an extension of an existing route, in case the number of tracks is not increased beyond the number for which consent originally was obtained, on and along any part of a street or public way upon which a street railway has been operated within one year preceding under a grant or renewal of a grant which has expired or within two years will expire or when such a grant is made by the legislative authority of a municipal corporation or the board of county commissioners of a county on and along any part of a street or public way upon the order or finding of any court of competent jurisdiction, or a judge of such court, in a hearing upon or growing out of a grade crossing elimination proceeding, in which hearing such court or judge has determined that the reasonable and practical solution of the manner of eliminating a grade crossing requires that such a street railway or interurban railroad be relocated or rerouted for a certain distance fixed by the court, it shall not be necessary to produce to the legislative authority or board any written consents from the owners of the lots and land abutting on such part of a street or public way.
This section does not permit a person owning property abutting on a street along, in, or over which a street railway is about to be constructed to withdraw his consent after an ordinance granting the right to construct and operate it has been read the second time, if at least thirty days elapsed since the first reading of such ordinance, in the legislative authority of the municipal corporation or other body authorized to make the grant.
