Whenever, as a result of any lawful order of any agency, other than a park district board, having authority to enforce any law or regulation designed for the protection, health or safety of employees or visitors, or any law or regulation for the protection and safety of the environment, pursuant to the “Environmental Protection Act”, any local park district, is required to alter or repair any physical facilities, or whenever after the effective date of this amendatory Act of 1985 any such district determines that it is necessary for health and safety, environmental protection, accessibility or energy conservation purposes that any physical facilities be altered or repaired, such district may, by proper resolution which specifically identifies the project and which is adopted pursuant to the provisions of the Open Meetings Act and upon the approval of a proposition by a majority of the electors voting thereon specifying the rate, levy a tax for the purpose of paying such alterations or repairs, or survey by a licensed architect or engineer, upon the equalized assessed value of all the taxable property of the district at the specified rate not to exceed .10% per year for a period sufficient to finance such alterations or repairs, upon the following conditions:
     (a) When in the judgment of the local park district board of commissioners there are not sufficient funds available in the operations, building and maintenance fund of the district to pay for such alterations or repairs so ordered or determined as necessary.
     (b) When a certified estimate of a licensed architect or engineer stating the estimated amount of not less than $25,000 that is necessary to make the alterations or repairs so ordered or determined as necessary has been secured by the local park district.
     The filing of a certified copy of the resolution or ordinance levying the tax shall be the authority of the county clerk or clerks to extend such tax; provided, that in no event shall the extension of such tax for the current and preceding years, if any, under this Section be greater than the amount so approved, and in the event such current extension and preceding extensions exceed such approval and interest, it shall be reduced proportionately.
     The county clerk of each of the counties in which any park district levying a tax under the authority of this Section is located, in reducing raised levies, shall not consider any such tax as a part of the general levy for park district purposes and shall not include the same in the limitation of any other tax rate which may be extended. Such tax shall be levied and collected in like manner as all other taxes of park districts.
     The proposition to impose a tax under this Section may be initiated by resolution of the local park district board and shall be certified by the secretary of the local park district board to the proper election authorities for submission in accordance with the general election law.
