 (from Ch. 46, par. 11-1)Sec. 11-1.         In counties not under township organization, the election  precincts shall remain as now established until changed by the Board of  County Commissioners, but said County Board may, from time to time,  change the boundaries of election precincts and establish new ones. In  counties under township organization, each town shall constitute at  least one election precinct. Insofar as is practicable, each precinct  shall be situated within a single congressional, legislative and  representative district and within a single municipal ward.  In order to situate each precinct within a single district or ward, the  County Board shall change the boundaries of election precincts after each  decennial census as soon as is practicable following the completion of  congressional and legislative redistricting.At any consolidated primary or consolidated election at which  municipal officers are to be elected, and at any emergency referendum at  which a public question relating to a municipality is to be voted on,  notwithstanding any other provision of this Code, the election authority  shall establish a polling place within such municipality upon the request  of the municipal council or board of trustees at least 60 days before the  election and provided that the municipality  provides a suitable polling place.  To accomplish  this purpose, the election authority may establish an election precinct  constituting a single municipality of under 500 population for all  elections, notwithstanding the minimum precinct size otherwise specified  herein.Notwithstanding the above, when there  are not more than 50 registered voters in a precinct who are entitled to  vote in a local government or school district election, the election  authority having jurisdiction  over the precinct  is authorized to reassign such voters to one or more  polling places in adjacent precincts, within or  without the election authority's jurisdiction, for that  election.  For the purposes of such local government or school district  election only, the votes of the reassigned voters shall be tallied and  canvassed as votes from the precinct of the polling place to which such  voters have been reassigned.  The election authority having  jurisdiction over the precinct shall approve all administrative and polling  place procedures.  Such procedures shall take into account voter convenience, and ensure that the  integrity of the election process is maintained and that the secrecy of the  ballot is not violated.Except in the event of a fire, flood or total loss of heat in a place  fixed or established by any election authority pursuant to this Section as  a polling place for an election, no election authority shall change the  location of a polling place so established for any precinct after notice of  the place of holding the election for that precinct has been given as  required under Article 12 unless the election authority notifies all  registered voters in the precinct of the change in location by first class  mail in sufficient time for such notice to be received by the registered  voters in the precinct at least one day prior to the date of the election.The provisions of this Section apply to all precincts, including  those where voting machines or electronic voting systems are used.If, as a result of the redistricting of legislative, representative, or  congressional districts following a decennial census, there exists a census  block with only one voter that is the only census block in a precinct that is  in a legislative, representative, or congressional district, then the county  board, at any meeting of the county board, may change the precinct boundaries  so that the census block is within a precinct that has more than one voter in  the legislative, representative, or congressional district.
