Fairburn Mayor Mario Avery announced Tuesday that he would not be seeking re-election.

Avery, in a letter to residents, said he hoped to leave the city “in good standing” for the next mayor. He has held the position for more than seven years.

Avery did not say in the letter why he had decided not to run for office.

He did list several “success stories” during his tenure, saying he wanted to thank city employees who “created so much wealth, jobs, fun recreational activities and massive economic development together as a team.”

Avery cited several projects, including negotiations to bring a satellite location of Atlanta Metropolitan State College to the city, a newly renovated Duncan Park pool and splash pad and jobs from Google, Smuckers, Duracell and Sonoco.

Avery will be at the Oct. 7 Fairburn Fall Festival to thank residents for their support.
