Two or more city health districts may be united to form a single city health district by a majority affirmative vote of the legislative authority of each city affected by the union.
If at least three per cent of the qualified electors residing within each of two or more city health districts sign a petition proposing a union into a single city health district, an election shall be held as provided in this section to determine whether a single city health district shall be formed. The petition for union may specify regarding the board of health of the new district:
Such petition shall be filed with the boards of county commissioners of the respective counties affected, subject to approval of the director of health, and such boards shall promptly certify the text of the proposal to the boards of election for the purpose of having the proposal placed on the ballot at the next general election occurring more than ninety days after such certification. The election procedures provided in Chapter 3505. of the Revised Code for questions and issues shall apply to the election. If a majority of the electors voting on the proposal in each of the health districts affected vote in favor thereof, the union of such districts into a single city health district shall be established on the second succeeding first day of January.
