The Westhaven Residents Club will be used as a new voting precinct for more than 2,400 residents in western Franklin, including those who live in the Westhaven, Willow Springs and Franklin Green subdivisions.
Affected voters formerly used Grace Chapel on Southall Road near Leiper's Fork.
The change comes in time for the Aug. 7 state primary and county general elections and the Nov. 4 presidential election.
"As areas of Franklin grow, we're going to have a new voting precinct," said Chad Gray, deputy administrator for county election commission.
"We're trying to get some of our precincts more balanced before the November election."
Notices were sent earlier this week to 2,431 voters who previously used Precinct 2-2 at Grace Chapel. The Westhaven precinct will be known as Precinct 2-4.
