1.    The number of park commissioners may be increased from three to five, or decreased from five to three, pursuant to this section.

2.    The process for increasing or decreasing the number of park commissioners may be initiated:

a.    By resolution approved by a majority vote of the board of park commissioners and submitted to the governing body of the city; or

b.    By a petition signed by ten percent or more of the total number of qualified electors of the city park district voting for governor at the most recent gubernatorial election and submitted to the governing body of the city.

3.    The governing body of the city shall submit the question of increasing or decreasing the number of park commissioners to the electors of the park district at any regular city election or primary or general election as specified in the resolution or petition submitted pursuant to subsection 2. The question requires an affirmative vote of a majority of those voting on the question for passage.

4.    If an increase in the number of park commissioners is approved by the electors, the two additional park commissioners must be elected at the next regular city election or as specified in the resolution or petition pursuant to subsection 2. One of the additional commissioners shall hold office for a term of four years, and the other commissioner for a term of two years and until a successor is elected and qualified, unless other terms are specified in the resolution or petition pursuant to subsection 2.

5.    If a decrease in the number of park commissioners is approved by the electors, the existing board members shall continue in office until the time when the terms of office of two members of the board expire simultaneously. At that time, those two offices are abolished. A different procedure for abolition of the two offices may be specified in the resolution or petition pursuant to subsection 2.
