Ohio Rev. Code § 6101.30
If the report of the board of appraisers of a conservancy district includes recommendations that other lands and public corporations be included in the district or that certain lands and public corporations be excluded from the district, the clerk of the court before which the proceeding is pending shall give to the owners of that property and to the public corporations by publication notice of a hearing on the petition for the creation of the district. The notice to those owners whose lands are or the public corporations to be added to the district may be substantially as shown in section 6101.84 of the Revised Code. The time and place of the hearing may be the same as those of a hearing on appraisals. To the owners of property and public corporations to be excluded from the district, it is sufficient to notify them of that fact.
