    If a majority of all the votes cast upon the proposition shall be in favor thereof the county board shall thereafter annually levy a tax of not to exceed .25 per cent of the value, as equalized or assessed by the Department of Revenue, which tax shall be collected in like manner and with other general taxes in such county and shall be known as the "County Airport Fund", and thereafter the county board shall, in the annual appropriation bill, appropriate from such fund such sum or sums of money as may be necessary to defray all necessary expenses and liabilities of the county airport and landing field. The county board of any such county and the corporate authorities of any one or more taxing districts lying wholly or partly within the corporate limits of the county which taxing district or districts are authorized under the laws of this state to acquire, establish, operate and maintain airports and landing fields, may hereafter by agreement provide for the joint construction, maintenance and control of an airport and landing field. Such agreement shall specify the site of the proposed airport and landing field and the proportionate share of the cost of construction and the cost of maintenance which shall be borne by such county and each of such taxing districts. The County Board shall certify the proposition for such joint construction, maintenance and control to the proper election officials, who shall submit the proposition to the voters of the county and each such taxing district at an election in accordance with the general election law. The proposition shall state the proposed site of such airport and landing field and the proportionate share of the cost of construction and maintenance to be borne by the respective governmental units concerned.
    If the proposition is approved by a majority of the voters in the county and any taxing district voting on the proposition, the corporate authorities of each such governmental unit may, irrespective of any limitation of rate in any other act or provision to the contrary, levy a tax subject to such further limitation as may be occasioned by the issue of bonds as hereinafter provided, not to exceed .25 per cent of the value, as equalized or assessed by the Department of Revenue, annually on all taxable property of such governmental unit. Such tax shall be levied and collected in like manner with the general taxes of such governmental unit and shall form when collected a fund to be known as the "County Airport Fund" and deposited with the County Treasurer of the County. Such tax shall be in addition to all other taxes which such governmental unit is now or hereafter may be authorized to levy on the aggregate of all property therein, and shall not be included within the rate for general corporate purposes for each such governmental unit but shall be in addition thereto and exclusive thereof; and each such governmental unit shall appropriate such sum or sums as its proportionate share shall be under the agreement as may be necessary to defray all necessary expenses and liability of such airport and landing field.
    If such proposition is approved by a majority of the voters in the county and each of the taxing districts voting on the proposition, the corporate authorities of each such governmental unit shall appoint 3 directors. The qualifications, terms of office and removal of such directors shall be as provided in Sections 3 and 4 of this Act, and vacancies shall be filled in the manner as provided in Section 5 hereof. The directors so appointed shall constitute a joint Board of Directors for the control and management of the airport and landing field. The joint Board of Directors shall exercise the powers and be subject to the duties prescribed in this Act for Board of Directors of airports and landing fields. The corporate authorities of each of such governmental units shall annually appropriate funds for the maintenance and operation of the airport in the proportion set forth in the proposition adopted, for the use of the Airport Fund and shall levy the tax herein provided, or so much of such rate as will provide the sum, and may issue bonds as provided in this Act for the purpose of defraying its proportionate share of the costs of construction and maintenance of the airport and landing field.
    If any county or taxing district shall issue bonds as hereinafter provided, then so long as taxes are required to be levied and extended to pay the principal of and interest on such bonds, the rate extended in any year for the benefit of the Airport Fund shall be limited to the amount by which .25 per cent of the value, as equalized or assessed by the Department of Revenue, exceeds the rate extended in such year to pay such principal and interest on such bonds. The foregoing limitations upon tax rates may be increased or decreased under the referendum provisions of the General Revenue Law of Illinois.
