(1) The county board in counties in this state in which a facility has been established as provided in section 23-3501 may, by a majority vote of the board, issue and sell bonds of the county in such sums as the county board may deem advisable to defray the cost of improvements or additions thereto, equipment, and other property deemed necessary for operation of the facility.
(2) Such bonds shall (a) be payable in not to exceed thirty years after the date of issuance, (b) bear interest payable annually or semiannually, and (c) contain an option to the county to pay all or any part thereof at any time after five years after the date of issuance. When such bonds have been issued under this section or section 23-3501, the county board shall cause to be levied and collected annually a tax upon all of the taxable property of such county sufficient to pay the interest and principal of the bonds as the interest and principal become due and payable. If the county board deems it appropriate, the county board may submit to the electors of such county at a general or special election the question of whether to exceed the tax limitation set forth in Article VIII, section 5, of the Constitution of Nebraska or any other applicable statutory levy limitation.
(3) Any taxes levied to pay bonds issued under this section or section 23-3501 shall be kept in a separate fund in the county treasury. Any such bonds shall not be deemed to be payable from the general fund of the county.
(4) This section shall not apply to any bond or other indebtedness authorized by the board of trustees pursuant to section 23-3504.
