To take advantage of the increased limiting rate for levy year 2009 approved by a majority of voters voting on the proposition at the general primary election held on February 2, 2010, the Board of Park Commissioners of the Park District of Forest Park may adopt an additional or supplemental budget under the sole authority of this Section by a vote of a majority of the full membership of the board, any other provision of this Article to the contrary notwithstanding, in and by which the additional or supplemental budget the board shall appropriate the additional sums of money as it may find necessary to defray expenses and liabilities of the district to be incurred for corporate purposes of the district during that fiscal year, but not in excess of the additional funds estimated to be available by the voted increased limiting rate for levy year 2009. The additional or supplemental budget shall be regarded as an amendment of the annual budget for the fiscal year in which it is adopted. The board may immediately levy the additional tax for corporate purposes to equal the amount of the additional sums of money appropriated in the additional or supplemental budget.
