The board of county commissioners of any county having a population of more than three hundred thousand may establish and maintain, in a bank located in such county, not to exceed ten thousand dollars in an imprest fund, known as the coliseum events fund, from which the expenses of operation and promotion of events held in a county coliseum may be paid. The coliseum director of any such county shall have authority to pay moneys from such fund for expenses incidental to shows or events promoted in the coliseum, by check drawn on the fund and signed by the coliseum director. All receipts from events and shows held in the coliseum, after the payment of expenses, shall be deposited in the fund, and the balance in excess of the maximum amount authorized to be in such fund shall be transferred by the county treasurer to the special recreation facilities fund created under Kan. Stat. Ann. § 19-2692a for purposes of budgeting for and operating a coliseum.
