In addition to its general fund levy authority, a board of park commissioners established pursuant to chapter 40-49 may levy taxes annually not exceeding five mills per dollar of taxable valuation in the district for a fund for the purpose of acquiring real estate as a site for public parks, construction of recreational facilities, renovation and repair of recreational facilities, and the furnishing of recreational facilities. The tax is to be levied, spread, and collected in the same manner as are other taxes in the park district. The question of whether the levy is to be discontinued must be submitted to the qualified electors at the next regular election upon petition of twenty-five percent or more of the qualified electors voting in the last regular park district election, if the petition is filed not less than sixty days before the election. If the majority of the qualified electors voting on the question vote to discontinue the levy, it may not again be levied without a majority vote of the qualified electors voting on the question at a later regular     election on the question of relevying the tax, which question may be submitted upon petition as above provided or by decision of the governing board.
