Ohio Rev. Code § 6101.32
Upon the filing of the report of the board of appraisers of a conservancy district under section 6101.31 of the Revised Code, the clerk of the court shall give notice of the filing by publication in each county in the district in which property included in the conservancy appraisal record is located. The notice shall be substantially as set forth in division (F) of section 6101.84 of the Revised Code. It is not necessary for the clerk to name the parties interested, and the notice shall be addressed "To All Persons or Public Corporations Interested." It is not necessary to describe separate lots or tracts of land in giving the notice, but the heading of the notice and the text of it shall give, and it is sufficient if each gives, descriptions that will enable the owner of land or the owner of an interest of record in land to determine whether the owner's land or interest is covered by the descriptions. For instance, it is sufficient to state in the heading "NOTICE OF HEARING ON APPRAISALS ON LANDS LYING IN____________________, ____________________, and____________________ TOWNSHIPS AND IN THE CITIES OR VILLAGES OF____________________, ____________________, and____________________ in ____________________ COUNTY," and it is sufficient to state in the text "All land lying in the____________________ ward of the city of____________________," or "All land abutting on ____________________ street in the city of____________________," or "All land lying west of____________________ river and east of ____________________ railroad in____________________ township," or any other general description pointing out the lands involved.
If lands in different counties are mentioned in the report, it is not necessary to publish a description of all the lands in the district in each county, but only of that part of the lands located in the county in which publication is made.
The board of directors of the conservancy district, on or before the date of the publication of the notice provided for in this section, shall mail by first class mail to the applicable public corporations and to all other known persons having an interest of record in property that is to be taken or is damaged and whose tax mailing or other known address is disclosed by the affidavit referred to in this section a notice that shall be directed to the appropriate address, shall advise the addressee of the date of the filing and place of filing of the report of the board of appraisers, and shall state that the addressee has the right to file exceptions to the report on or before a specified date and to be heard in the county where the addressee's property is located at the time and place fixed by the court as provided by section 6101.33 of the Revised Code. The notice shall contain a statement that the property to be taken or the damage has been appraised and shall give the dollar amount of that appraisal.
The secretary of the conservancy district, or the secretary's deputy, as ex officio secretary of the board of appraisers, shall prepare and file with the clerk of the court on the date of the mailing of the notices provided for in this section an affidavit attesting in substance that, as of the date of the mailing of the notices, the affiant has determined that the names of all applicable public corporations, and the names of the owners of property that is to be taken or that is damaged, where those names are ascertainable, together with their respective tax mailing or other known addresses where ascertainable, are listed in the report of the board of appraisers with the exception of differing names or addresses specifically set forth in the affidavit; that no names and no tax mailing or other known addresses are ascertainable except as may be disclosed by the report as supplemented by the affidavit; and that notices have been mailed as provided for in this section to each public corporation and to all other persons having an interest of record in property that is to be taken or that is damaged and whose interest is known or can be ascertained from the record. The affidavit shall be given on the basis of available information and after the exercise of reasonable diligence, and it shall so state. The affidavit shall be prima-facie evidence of the matters attested to in it.
