    Sec. 115-20. Referendum on recommended plan; petition.
    (a) If the board recommends adoption of the open space plan, or if a subsequent petition is filed by not less than 5% or 50, whichever is greater, of the registered voters of the township (according to the voting registration records at the time the petition is filed) recommending adoption of the open space plan, then the Board, within 30 days of making of the recommendation or the approval of the petition, shall file a petition with the township clerk, requesting the clerk to submit to the voters of the township the question of whether the township shall adopt the open space plan and enter upon an open space program, with the power to acquire open land by purchase, condemnation (except townships in counties having a population of more than 150,000 but not more than 250,000), or otherwise in the township and with the power to issue bonds for those purposes under this Article. Approval of a petition recommending adoption of the open space plan shall be given if the petition is determined to be valid following public notice and a hearing consistent with the requirements of Section 115-10 for the initial petition. The total amount of bonds to be issued under this Section may not exceed 5% of the valuation of all taxable property in the township and shall be set forth in the question as a dollar amount. The township clerk shall certify that proposition to the proper election officials, who shall submit the proposition to the township voters at the next regular election. The referendum shall be conducted and notice given in accordance with the general election law.
    (b) The question submitted to the voters at the election shall be in substantially the following form:
        Shall (name of township) adopt the open space plan
    
considered at the public hearing on (date) and enter upon an open space program, and shall the Township Board have the power (i) to acquire open land by purchase (insert ", condemnation," if the township is in a county having a population of more than 250,000) or otherwise, (ii) to issue bonds for open space purposes in an amount not exceeding $(amount), and (iii) to levy a tax to pay the principal of and interest on those bonds, as provided in Article 115 of the Township Code?
The votes shall be recorded as "Yes" or "No".
    (c) If a majority of the voters voting at the election on the question vote in favor of the question, the township shall thereafter adopt the open space plan recommended by the board or by the petition of the registered voters of the township and shall enter upon an open space program under this Article. If the proposition does not receive the approval of a majority of the voters voting at the election on the question, no proposition may be submitted to the voters under this Section less than 23 months after the date of the election.
    (d) If a majority of the legal voters voting at referendum in any township approved a proposition at the consolidated election in 2001 in reliance upon and consistent with this Section 115-20 as it existed prior to the effective date of Public Act 91-847, then that referendum and all actions taken in reliance thereon are hereby validated and are legally binding in all respects.
