 (from Ch. 24, par. 7-1-11)Sec. 7-1-11.         The following is an optional method of annexing any  territory which, (1) is not less than one square mile in area; (2)  contains at least 500 inhabitants; (3) is not included within any  municipality; and (4) is contiguous to a municipality having not more  than 100,000 inhabitants. Such territory may be annexed to a  municipality of the specified sort as follows:A petition, signed by not less than 100 of the electors of the  territory sought to be annexed and by the owners of record of more than  50% of such territory, shall be filed with the circuit court for the  county in which the territory is situated. The petition shall request  that the question of annexation of the territory described therein be  submitted to the electors of the territory.No tract of land in excess of 10 acres in area shall be included in  the annexation petition without the express consent of the owner thereof  unless the tract is(1) subdivided into lots or blocks; or(2) bounded on at least 3 sides by lands subdivided into lots or  blocks.The owner of record of land comprising any part of the perimeter of  the territory sought to be annexed may apply to the court for the  exclusion of his land from the territory described in such petition. The  court shall grant such application if the exclusion of such land will  not destroy the contiguity of the land sought to be annexed with the  annexing municipality.After considering any such application, the court shall order the question  submitted within the territory at an election in accordance  with the general election law. The clerk of the circuit court shall certify  the question to the proper election authority for submission.  The result of the election shall be entered of record in the court.  If a majority of the votes cast on the question  favor annexation, the  court shall then give notice thereof to the corporate authorities of the  proposed annexing municipality. The corporate authorities shall then  vote on the question of such annexation and if a majority of their  membership, by a vote recorded in the minutes, vote in favor of the  annexation, an ordinance shall be passed annexing the territory. The  clerk of the annexing municipality shall certify and file a copy of the  annexation ordinance with a map showing the boundary lines of the  territory annexed, with the recorder of the county in which the  municipality is located and a document of annexation shall be filed with  the county clerk and County Election Authority.If the question of such annexation does not receive the requisite  majority vote of the corporate authorities, the municipal clerk  shall certify the question at an election in accordance with the general election law.If a majority of persons voting upon the question vote for  annexation, the described territory is annexed to the annexing  municipality. The clerk of the annexing municipality shall certify and  file a statement of the annexation proceeding with a map showing the  boundary lines of the territory annexed, as provided in this section.If a majority of persons voting on the question vote against  annexation, no further proceedings shall be had on the question for at  least 22 months from the date of such election.
