The governing body of any city or county by the appropriate ordinance or resolution, may authorize the issuance of general obligation bonds to provide for the payment of all or any portion of the cost of any public facilities or improvements for which such city or county is otherwise authorized pursuant to the constitution or laws of this state to issue general obligation bonds. The governing body may pledge revenues received from countywide or city retailers’ sales taxes imposed pursuant to Kan. Stat. Ann. § 12-187 et seq., and amendments thereto, for the payment of such bonds. The pledge of revenues received from countywide or city retailers’ sales taxes for payment of such bonds shall constitute an irrevocable pledge of the revenues and shall be made a lien on the revenues for the benefit of bondholders. Any bonds issued under this section shall be subject to the following requirements:

(a) Before the governing body of any city or county shall issue any general obligation bonds as authorized herein, the governing body shall cause to be prepared a comprehensive feasibility study showing that revenues received from a countywide or city retailers’ sales tax would be sufficient to retire such bonds.

(b) Such bonds shall constitute a general obligation of the city or county payable from the pledged revenue received from countywide or city retailers’ sales taxes and if not so paid such bonds shall be payable from ad valorem taxes which for the purpose of paying such bonds may be levied without limit as to rate or amount by the city or county, and shall be printed as provided in Kan. Stat. Ann. § 10-112, and amendments thereto.

(c) Any bonds issued under the provisions of this section and the interest thereon, shall be exempt from all taxes levied by the state of Kansas or any political or taxing subdivision thereof.

(d) All bonds which are to be financed in accordance with the provisions of this section shall be subject to any statutory limitation of bonded indebtedness imposed on a city or county unless:

(1) The law authorizing the issuance of such bonds specifically excludes such bonds from any statutory limitation of bonded indebtedness;

(2) the bonds are excluded from the computation of bonded indebtedness pursuant to Kan. Stat. Ann. §§ 10-307 or 10-309, and amendments thereto; or

(3) the bonds are issued by Douglas county or Sherman county.

(e) In the event the governing body of a city or county proposes to issue such bonds, and the question of issuing bonds as authorized herein has not previously been submitted to and approved by the voters of the city or county such proposition shall be published once each week for two consecutive weeks in its official newspaper. If within 30 days after the last publication of the proposition, a petition is filed with the county election officer signed by not less than 5% of the electors of the city or county who voted in the last preceding general election of the city or county, then no such bonds shall be issued unless the proposition is submitted to and approved by a majority of the voters of the city or county voting at an election held thereon. Any such elections shall be called and held in accordance with the provisions of Kan. Stat. Ann. § 10-120, and amendments thereto, or in accordance with the provisions of the mail ballot election act.
