The board of county commissioners of any such county may, upon the establishment of such mental health clinic, levy an annual tax upon all taxable tangible property in such county and the proceeds thereof shall be placed in the hands of the treasurer of said board of trustees, to be administered as provided by Kan. Stat. Ann. §§ 65-214 and to pay a portion of the principal and interest on bonds issued under the authority of Kan. Stat. Ann. § 12-1774, and amendments thereto, by cities located in the county. No levy shall be made under the provisions of this act until a resolution authorizing the making of such levies be passed by the board of county commissioners by publication for three successive issues in a newspaper of general circulation within the county, whereupon such levies may be made unless a petition in opposition to the same, signed by not less than ten percent (10%) of the qualified electors of such county as determined by the vote for secretary of state in the last preceding election, is filed with the county clerk of such county within thirty (30) days following the last publication of said resolution.

In the event such petition is filed it shall be the duty of the board of county commissioners to submit the question to the voters at an election called for such purpose or at the next general election. The provisions of this act shall be supplemental to other existing health laws in the counties affected thereby, but shall in no way abrogate, or amend any such other existing health laws.
