The board of county commissioners of any county in which there is an officially recognized county fair association, upon the request of such fair association, may make an annual tax levy for the purpose of raising funds to be used for the purchase of grounds and the erection and maintenance of buildings of such fair associations 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 exceed a rate, which multiplied by the total assessed tangible valuation of the county, will result in producing more than $33,000 and an amount 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 in any one year. The tax levy authorized shall be in addition to all other tax levies authorized or limited by law and shall not be subject to or within the aggregate tax levy limit prescribed by Kan. Stat. Ann. § 79-1947, and amendments thereto. The amount collected by the county for such purpose, except for an amount 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, shall be paid to such fair associations for the purposes herein specified, upon request of such fair association. The fair association may use any portion of this amount, not needed for purchase of grounds and the erection and maintenance of buildings, to supplement and increase premiums and awards for exhibitions by 4-H members and organized F.F.A. members.
