Ohio Rev. Code § 5555.27
As soon as the county engineer has transmitted to the several boards of county commissioners copies of the engineer's surveys, plans, profiles, cross sections, estimates, and specifications for the improvement, the joint board of county commissioners shall, except in cases of reconstruction or repair of roads where no lands or property are taken, fix a time and place for hearing objections to said improvement. The joint board shall thereupon, except in cases of reconstruction or repair of roads where no lands or property are taken, publish in a newspaper of general circulation within each interested county, once a week for two consecutive weeks or as provided in section 7.16 of the Revised Code, a notice that such improvement is to be made and that copies of the surveys, plans, profiles, cross sections, estimates, and specifications therefor are on file in the office of the board of each interested county for the inspection and examination of all persons interested therein. Such notice shall also state the time and place for hearing objections to said improvement. Proceedings for the appropriation of land needed for such improvement shall be maintained in accordance with sections 163.01 to 163.22 of the Revised Code.
