    Sec. 2-3-5a. Incorporation of village.
    (a) Whenever in any county of 150,000 or more population as determined by the last preceding federal census any area of contiguous territory contains at least 4 square miles and 2500 inhabitants residing in permanent dwellings, that area may be incorporated as a village if a petition filed by 250 electors residing within that area is filed with the circuit clerk of the county in which such area is located addressed to the circuit court for that county. The petition must set forth:
        (1) a legal description of the area intended to be
    
included in the proposed village,
        (2) the number of residents in that area,
        (3) the name of the proposed village, and
        (4) a prayer that the question of the incorporation
    
of the area as a village be submitted to the electors residing within the limits of the proposed village.
    If the area contains fewer than 7,500 residents and lies within 1 1/2 miles of the limits of any existing municipality, the consent of that municipality must be obtained before the area may be incorporated.
    (b) If, in a county having more than 240,000 but fewer than 400,000 inhabitants as determined by the last preceding federal census, an area of contiguous territory contains at least 3 square miles and 5,000 inhabitants residing in permanent dwellings, that area may be incorporated as a village in the same manner as is provided in subsection (a). The consent of a municipality need not be obtained.
    (c) If, in a county having more than 316,000 but fewer than 318,000 inhabitants as determined by the last preceding federal census, an area of contiguous territory that does not exceed one square mile and between 1000 and 1500 inhabitants residing in permanent dwellings, and is located within 10 miles of a county with a population of less than 150,000 as determined by the last preceding federal census, that area may be incorporated as a village in the same manner as is provided in subsection (a). The consent of a municipality need not be obtained.
    (d) If, in a county having more than 400,000 but fewer than 410,000 inhabitants, as determined by the last preceding federal census, an area of contiguous territory not exceeding one square mile contains at least 400 inhabitants residing in permanent dwellings and is located in a township adjacent to a county of less than 150,000 inhabitants, as determined by the last preceding federal census, then that area and the area adjacent thereto and also within such township, not exceeding, however, 4 square miles in total, may be incorporated as a village in the same manner as provided in subsection (a). Neither the consent of a municipality nor the finding of the county board under Section 2-3-18, if otherwise applicable, need be obtained.
