Ohio Rev. Code § 5559.08
If, after determination of all claims for compensation and damages on account of land or property taken for an improvement under section 5559.02 of the Revised Code, the board of county commissioners is still satisfied that the public convenience and welfare require that such improvement be made, and that the cost will not be excessive, in view of the public utility thereof, such board shall order, by resolution, that it proceed with the improvement, and shall adopt the surveys, plans, profiles, cross sections, estimates, and specifications therefor, as reported by the county engineer, or with such modifications as the board and engineer may agree upon.
If, in view of the amount of the compensation and damages allowed, or for any other just cause, such board is of the opinion that the improvement should not be made, the board shall so order.
