In any county electing a county charter commission, the board of county commissioners shall appropriate money for the expenses of such commission in the preparation of a county charter, or charter amendment, and the study of problems involved. No appropriation shall be made for the compensation of members of the commission for their services. The board shall appropriate money for the printing and mailing or otherwise distributing to each elector in the county, as far as may be reasonably possible, a copy of a charter submitted to the electors of the county by a charter commission or by the board pursuant to petition as provided by Section 4 of Article X, Ohio Constitution. The copy of the charter shall be mailed or otherwise distributed at least thirty days prior to the election. The board shall appropriate money for the printing and distribution or publication of proposed amendments to a charter submitted by a charter commission pursuant to Section 4 of Article X, Ohio Constitution. Notice of amendments to a county charter shall be given by mailing or otherwise distributing a copy of each proposed amendment to each elector in the county, as far as may be reasonably possible, at least thirty days prior to the election or, if the board so determines, by publishing the full text of the proposed amendments once a week for at least two consecutive weeks in a newspaper of general circulation within the county, or as provided in section 7.16 of the Revised Code. No public officer is precluded, because of being a public officer, from also holding office as a member of a county charter commission, except that not more than four officeholders may be elected to a county charter commission at the same time. No member of a county charter commission, because of charter commission membership, is precluded from seeking or holding other public office.
