In any year in which the board proposes to levy the additional 0.02% tax, the board shall adopt an ordinance determining to levy the tax. The ordinance may be vacated by the board before its publication.
Within 15 days after the adoption of the ordinance, it shall be published in accordance with Section 1-30. The publication or posting of the resolution shall include a notice of (i) the specific number of voters required to sign a petition requesting that the question of the adoption of the resolution be submitted to the electors of the district, (ii) the time in which the petition must be filed, and (iii) the date of the prospective referendum.
The secretary of the district shall provide a petition form to any individual requesting one.
If no petition is filed with the board within 30 days after publication or posting of the ordinance, the district shall then be authorized to levy the tax. If, however, within the 30 day period a petition is filed with the board, signed by electors of the district equal in number to 10% or more of the total number of registered voters in the district, asking that the question of levying a 0.02% tax be submitted to the electors of the district, the question shall be certified to the proper election authority, who shall submit the question at an election in accordance with the Election Code, unless the board vacates the ordinance within 7 days after the petition is filed.
