(a) When 2 or more park districts are situated entirely within the corporate limits of the same municipality, a park district coterminous with such municipality may be organized in the manner hereinafter provided, and, when so organized, shall supersede the park districts previously existing within the limits of the municipality. The petition to organize such a park district shall comply with the requirements of Section 2-2, but must be signed by not less than 100 legal voters residing in each of the existing park districts and, if the municipality includes territory not included within any existing park district, by at least 100 legal voters residing in such territory or by at least 10% of the legal voters residing in such territory, whichever is less. The petition shall also state whether the proposed district shall have 5 elected commissioners or 7 appointed commissioners. If the proposed district shall have 7 appointed commissioners, the chief executive officer of the municipality, with the advice and consent of the corporate authorities, shall appoint the commissioners. The initial appointed commissioners shall serve terms determined by lot as follows: 2 for terms of 2 years, 2 for terms of 4 years, and 3 for terms of 6 years. Thereafter, appointed commissioners shall serve for terms of 6 years. A vacancy in the office of appointed commissioner shall be filled for the unexpired term in the same manner as an original appointment. “Municipality” as used in this Section means a city, village or incorporated town.
