(70 ILCS 1005/10) (from Ch. 111 1/2, par. 83)
    Sec. 10. Any territory lying adjacent and contiguous to a mosquito abatement district, and not part of another mosquito abatement district, may be annexed to such district in the following manner:
    (a) Upon petition in writing, describing the territory proposed to be annexed and signed by a majority of the legal voters in such territory and by the owners of more than half of the taxable property in such territory as shown by the last ascertained equalized value of the taxable property in such territory, being filed with the trustees of such mosquito abatement district, such trustees may annex such territory by a resolution which shall be published at least once in a newspaper having a general circulation in the territory and shall include a notice of (1) the specific number of voters required to sign a petition requesting that the question of the adoption of the resolution be submitted to the electors of the territory; (2) the time in which the petition must be filed; and (3) the date of the prospective referendum. The county clerk of the county in which the territory is situated shall provide a petition form to any individual requesting one. The resolution shall be effective 30 days from the date of publication and is subject to a referendum, if such referendum is requested, prior to the effective date of the resolution, by the voters in the district equal to 10% or more of the registered voters in the district. Such trustees may also order the question of the annexation of such territory to be submitted to the legal voters of such district at a regular election therein by certifying the question to the proper election officials. Notice of such election shall be given and the election conducted in the manner provided by the general election law. The proposition shall be stated, "Shall the territory (describing it) be annexed to The.... Mosquito Abatement District?" If the majority of all the votes cast on the question is in favor of such annexation, the board of trustees shall so certify to the county clerk, and within ten days of such election the trustees by an order duly entered upon their records shall annex such territory to the district and shall file a map of the annexed territory in the office of the county clerk of the county where the annexed territory is situated. Thereupon such territory shall be deemed annexed to and shall be a part of such mosquito abatement district.
    (b) Whenever a mosquito abatement district contains over 90% of territory of a specific city or village, the mosquito abatement district may annex additional adjacent and contiguous territory within that city or village, but not incorporated within a mosquito abatement district, by the passage of an ordinance to that effect.
    The ordinance authorizing the annexation shall be published within 10 days after the ordinance has been adopted, in one or more newspapers having a general circulation within the territory. The publication of the ordinance shall be accompanied by a notice of (1) the specific number of voters required to sign a petition requesting the question of annexation; (2) the time within which the petition must be filed; and (3) the date of the prospective referendum. The county clerk of the county in which the territory is situated shall provide a petition form to any individual requesting one.
    The ordinance shall take effect 30 days after the date of publication unless a referendum is requested prior to the effective date of the ordinance by 10% or more of the registered voters in the territory. The question of the annexation of the territory may be submitted to the legal voters of the territory at a regular election by certifying the question to the proper election officials. Notice of the election shall be given and the election conducted in the manner provided by the general election law. The proposition shall be stated, "Shall the territory (describing it) be annexed to The.... Mosquito Abatement District?" If the majority of all the votes cast on the question is in favor of the annexation, the territory shall be deemed annexed to and shall be a part of the mosquito abatement district.
    No territory may be annexed under this subsection (i) more than one year after it has first been included in that city or village unless the territory so annexed is 50 acres or less or (ii) if the annexation would expand the mosquito abatement district's boundaries outside of a county unless the district already contains territory in that county.
