(a) The county board of elections shall select and fix the polling place within each new election district and may, at any time, for any reason that may seem proper to it, either on its own motion or on petition of ten qualified registered electors of an election district, change the polling place within any election district. Except in case of an emergency or unavoidable event occurring within twenty days of a primary or election, which renders any polling place unavailable for use at such primary or election, the county board shall not change any polling place until at least five days after notice of the proposed change shall have been posted on the existing polling place and in the immediate vicinity thereof, and until at least five days after written notice of the proposed change shall have been given to the occupant or owner of said polling place, or their agent.

(b) Except in case of emergency or unavoidable event, occurring within twenty days of a primary or election, which renders any polling place unavailable for use, if a petition be presented to the county board on or before the day set for hearing of the petition for change of polling place, signed by a majority of the registered electors of the district, objecting to the proposed change, said change shall not be ordered.

(c) The county board of elections shall publicly announce, not less than twenty days prior to the primary election, special election, municipal election or general election, by posting at its office in a conspicuous place, a list of the places at which the election is to be held in the various election districts of the county. The list shall be available for public inspection at the office of the county board of elections.
