Section 5-610. Registration records; new election district

When an election
  district  is  created,  abolished  or  altered  in any way, the board of
  elections shall  do  all  things  necessary  to  transfer  the  affected
  registration  records  to  conform to the new plan of election districts
  and shall make all necessary changes in the designation of the  election
  district  and  political  subdivision on the registration record of each
  voter affected. At least twenty days before  the  next  election,  after
  such  new  plan  of  election  districts has been effected, the board of
  elections shall mail a written notice to each affected registered  voter
  notifying  him  of  the designation of the new political subdivision, if
  any, and the number of the election district to which  his  registration
  record  has  been  transferred,  and  if  available,  the address of his
  polling place.
