(A) Whenever an official census shows that the city contains more or fewer wards than it is entitled to, the City Council, by ordinance, shall redistrict the city into as many wards as the city is entitled to. This redistricting shall be completed not less than 30 days before the first day set by the general election law for filing of candidate petitions for the next succeeding election for city officers. At that election there shall be elected the number of Aldermen to which the city is entitled, except as provided in division (B).
(B) If it appears from any official census that the city has the requisite number of inhabitants to authorize it to increase the number of Aldermen, the City Council shall immediately proceed to redistrict the city and shall hold the next city election in accordance with the new redistricting. At this election, the Aldermen whose terms of office are not expiring shall be considered Aldermen for the new wards respectively in which their residences are situated. If there are two or more Aldermen with terms of office not expiring and residing in the same ward under the new redistricting, the Alderman who holds over for that ward shall be determined by lot in the presence of the City Council, in the manner directed by the Council, and all other Aldermen shall fill their unexpired terms as Aldermen-at-large. The Aldermen-at-large, if any, shall have the same powers and duties as all other aldermen, but upon the expiration of their terms the offices of Aldermen-at-large shall be abolished.
(C) If the redistricting results in one or more wards in which no aldermen reside whose terms of office have not expired, two Aldermen shall be elected in accordance with the provisions of the ILCS Ch. 65, Act 5, §§ 3.1-20-25 and 3.1-20-35.
(D) A redistricting ordinance that has decreased the number of wards of the city because of a decrease in population of the city shall not be effective if, not less than 60 days before the time fixed for the next succeeding general municipal election, an official census is officially published that shows that the city has regained a population that entitles it to the number of wards that it had just prior to the passage of the last redistricting ordinance.
