70 ILCS 705/15c
Whenever any property within a fire protection district is located in a home rule municipality that provides fire service to at least 80% of the territory within the municipality's corporate limits, the home rule municipality may detach and disconnect that property from the fire protection district in the following manner:
The municipality may petition the court, setting forth in the petition the following: a description of the property sought to be detached and disconnected; a statement that the detachment and disconnection will not cause the property remaining in the district to be noncontiguous, that the loss of assessed valuation by reason of the disconnection of the described property will not impair the ability of the district to render fully adequate fire protection service to the property remaining with the district, that the property to be detached and disconnected will remain liable for its proportionate share of any outstanding bonded indebtedness of the district, that a response-time study has been conducted and the study is attached to the petition showing, at a minimum, estimated response times from the fire protection district to the territory and estimated response times of the municipal fire department to the territory, and that it is a home rule municipality that provides for its own fire service to at least 80% of the territory within the municipality; and asking that the described property be detached and disconnected from the fire protection district. The petition shall be signed and sworn to by the mayor or village president pursuant to a resolution of the corporate authorities of the municipality authorizing the filing of the petition.
For the purpose of meeting the requirement of this Section that the detachment and disconnection will not cause the remaining property to be noncontiguous, property shall be considered to be contiguous if the only separation between parts of the property is land owned by the United States, the State, or any agency or instrumentality of either, or any regional airport authority.
Upon the filing of the petition, the court shall set the same for hearing on a day not less than 2 weeks nor more than 4 weeks from the filing thereof and shall give 2 weeks' notice of such hearing in the manner provided in Section 1 of this Act. The fire protection district shall be a necessary party to the proceedings and it shall be served with summons in the manner prescribed for a party defendant under the Civil Practice Law. All property owners in such district, the district from which the transfer of property is to be made, and all persons interested therein may file objections, and at the hearing may appear and contest the detachment and disconnection of the property from the fire protection district, and both objectors and petitioners may offer any competent evidence in regard thereto. If the court, upon hearing such petition, finds that the petition complies with this Section 15c and that the allegations of the petition are true, the court shall enter an order detaching and disconnecting the property from the district, and upon entry of the order the property shall cease to be a part of the fire protection district and shall be serviced by the home rule municipality, except that the property remains liable for its proportionate share of any outstanding bonded indebtedness of the district. The circuit clerk shall transmit a certified copy of the order to the county clerk of each county in which any of the affected property is situated and to the Office of the State Fire Marshal.
