(70 ILCS 1205/9-2c) (from Ch. 105, par. 9-2c)
    Sec. 9-2c. Whenever the proposition is submitted to the voters of any park district to levy a tax for the purpose of acquiring, constructing, maintaining, and operating airports and landing fields for aircraft as provided in Section 9-2b, and a majority of the votes cast upon the proposition is in favor of the levy of such tax, the board of any such park district may provide that bonds of such park district be issued for the purpose of acquiring and constructing airports and landing fields for aircraft, or for the purpose of improving and extending such facilities when constructed. The bonds shall be authorized by ordinance of the board, shall mature serially in not to exceed 20 years from their date, and bear such rate of interest as the board may determine, not, however, to exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, payable semi-annually, and shall be sold by the board as it may determine but for not less than the par value thereof and accrued interest. The bonds shall be signed by the president (or such official as the board may designate) and secretary and countersigned by the treasurer with the corporate seal of the district affixed. The bonds shall be authorized by the board of the district by ordinance which shall fix all the details of the bonds and provide for a levy of a tax sufficient to pay the principal of and interest on the bonds as they mature. A certified copy of the ordinance shall be filed in the office of the clerk of the county wherein the park district is situated, and the county clerk shall extend a tax sufficient to pay the principal of and interest on the bonds as they mature without limitation as to rate or amount, and the county clerk shall reduce the tax rate levied by the district pursuant to Section 9-2b by the amount of the rate extended for payment of principal and interest of the bonds. The clerk shall extend the tax as provided in Section 6-6. If the rate necessary to be extended for the payment of principal and interest of the bonds exceeds the rate authorized to be levied by the district, pursuant to Section 9-2b, then the rate of tax for the payment of bonds and interest only shall be extended. Where the district is situated in more than one county the tax shall be certified, apportioned and levied as provided in Section 5-4. Notwithstanding the foregoing, after July 28, 1969, any park district may issue bonds under this Section for the purpose of maintaining, improving or replacing its existing airport facilities or landing fields to the extent required to conform to the standards of the Department of Transportation or of any appropriate federal agency relating to a State or federal airports plan or airways system. If such bonds are issued the tax levied for the payment of principal and interest of the bonds as they mature shall be in addition to that levied by the district under Section 9-2b and the county clerk shall extend both taxes accordingly. The aggregate principal amount of bonds issued under this Section that may be outstanding at any time may not exceed 1/2 of 1% of the aggregate valuation of all taxable property within the district, as equalized or assessed by the Department of Revenue. No bond ordinance may take effect nor may bonds be issued thereunder if the amount of bonds taken with the outstanding principal indebtedness under this Section exceeds the 1/2 of 1% limit unless the question of whether such additional bonds shall be issued is submitted to the legal voters of the district, in the manner provided by Section 6-4, and a majority of those voting on the proposition vote in favor thereof. In no event may the principal aggregate amount of any bonds issued under such ordinance exceed, together with the principal amount of bonds previously issued under this Section and then outstanding, 1 1/4% of the aggregate valuation of all taxable property within the district, as equalized or assessed by the Department of Revenue.
    Bonds issued under this Section are not a part of the existing indebtedness of a park district for purposes of Article 6 of this Code.
    With respect to instruments for the payment of money issued under this Section either before, on, or after June 6, 1989 (the effective date of Public Act 86-4), it is and always has been the intention of the General Assembly (i) that the Omnibus Bond Acts are and always have been supplementary grants of power to issue instruments in accordance with the Omnibus Bond Acts, regardless of any provision of this Act that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Act that may appear to be or to have been more restrictive than those Acts.
