Each precinct within any urban center shall contain not less than 300, nor more than 1,500 registered voters. Each precinct in a rural or less thickly settled area shall contain not less than 200, nor more than 700 registered voters. A county commission may permit the establishment or retention of a precinct less than the minimum numbers allowed in this subsection upon making a written finding that to do otherwise would cause undue hardship to the voters. If, at any time the number of registered voters exceeds the maximum number specified, the county commission shall rearrange the precincts within the political division so that the new precincts each contain a number of registered voters within the designated limits: Provided, That any precincts with polling places that are within a one-mile radius of each other on or after July 1, 2014, may be consolidated, at the discretion of the county clerk and county commission into one or more new precincts that contain not more than 3,000 registered voters in any urban center, nor more than 1,500 registered voters in a rural or less thickly settled area: Provided, however, That no precincts may be consolidated pursuant to this section if the consolidation would create a geographical barrier or path of travel between voters in a precinct and their proposed new polling place that would create an undue hardship to voters of any current precinct.
If a county commission fails to rearrange the precincts as required, any qualified voter of the county may apply for a writ of mandamus to compel the performance of this duty: Provided, That when in the discretion of the county commission, there is only one place convenient to vote within the precinct and when there are more than 700 registered voters within the existing precinct, the county commission may designate two or more precincts with the same geographic boundaries and which have voting places located within the same building. The county commission shall designate alphabetically the voters who are eligible to vote in each precinct so created. Each precinct shall be operated separately and independently with separate voting booths, ballot boxes, election commissioners and clerks, and whenever possible, in separate rooms. No two precincts may use the same standard receiving board, except as permitted by the provisions of §3-1-30(j) of this code.
