In accordance with state law (765 ILCS 205/6, 205/7 and 205/8), any plat or part thereof may be vacated by the owner of the tract, at any time before the sale of any lot therein, by a written vacation instrument to which a copy of the plat is attached. If there are public service facilities in any street, other public way, or easement shown on said plat, the instrument shall reserve to the village or other public entity or public utility owning such facilities the property, rights-of-way and easements necessary for continuing public service by means of those facilities and for maintaining or reconstructing the same. The vacation instrument shall be approved by the Board of Trustees in the same manner as plats of subdivision and shall also be approved by the County Superintendent of Highways, the Highway Commissioner of the appropriate township, the District Engineer of the State Department of Transportation, and the public utilities. In the case of the platted tracts wherein any lots have been sold, the written vacation instrument must also be signed by alt the owners of lots in said tracts.
