Any 2 or more contiguous park districts may be consolidated and become a single park district in the manner following: The park commissioners of each of the park districts desiring to consolidate shall adopt an ordinance by a vote of not less than 2/3 of the commissioners of each district, which ordinance shall duly set forth the intent of the park districts to consolidate with the contiguous park district or districts as therein set forth, shall designate the park district which shall be the survivor of the consolidation, and shall designate the names of the commissioners thereof, which commissioners shall, at the time of the consolidation be duly elected and acting commissioners of the districts concerned in the consolidation. A certified copy of said ordinances shall be filed in the office of the clerk of the county, or counties, within which any part of the consolidated park district shall be located.
Upon the adoption of the ordinances by the park districts concerned the park district designated in the ordinances as the survivor of the consolidation shall assume the functions previously performed by the park districts and the surviving park district shall have the power and authority to levy and collect such taxes at such rates as shall have been previously authorized, levied and collected by the designated survivor district.
All parks and other property owned by the districts adopting such ordinances shall thereupon be vested in the newly consolidated park district and the newly consolidated park district shall succeed to all of the outstanding rights and obligations of the districts concerned.
