KENNESAW — The Kennesaw City Council voted this week to establish Dec. 20 as the start date of Sunday alcohol sales if voters pass a referendum on the issue on Election Day in November.

Kennesaw was the first city in Cobb County to call for a referendum on Sunday alcohol sales in a May 2 vote. The general election is Nov. 8.

The council unanimously voted on the resolution Monday.

“The action taken by the Council establishes Dec. 20 as the date updates will be made to the municipal code related to alcohol sales on Sunday,” Kennesaw Mayor Mark Mathews said. “This update will only be required if voters approve Sunday sales on the Nov. 8 ballot.”

Dec. 20, which falls on a Tuesday, was chosen in Kennesaw because it was the earliest date that would give sufficient time for validating election results, then posting and conducting the two public hearings needed to change the municipal code, city spokeswoman Pam Davis said.

On April 28, Gov. Nathan Deal signed Senate Bill 10, paving the way for local communities to vote on allowing Sunday alcohol sales. The legislation passed in the General Assembly on April 12, after five years of failed attempts. Connecticut and Indiana are now the only states that ban the Sunday sale of alcohol.
