Cobb County commissioners are expected to weigh a temporary moratorium on new data centers in unincorporated parts of the county at Tuesday’s meetings, a move that could hit pause on permit and rezoning applications while officials sort out the fine print. The draft measure would put a 180‑day freeze in place, or keep the pause going until county leaders update the rules, as they wrestle with neighborhood impacts and mounting pressure on utilities.
Draft flags noise, air and utility impacts
A draft resolution circulating among commissioners spells out a list of potential harms, including "noise pollution; air quality impacts from cooling systems and backup generators; undesirable aesthetics; and significant effects on power and water utilities," according to WSB‑TV. The language notes commissioners have watched data centers proliferate across metro Atlanta and want breathing room to revisit zoning and permitting rules before more projects slip through under the current code.
When and where the commission will meet
The Board is scheduled to hold a work session at 1:30 p.m. and a public commission meeting at 7 p.m. on Tuesday, according to Cobb County's public meetings calendar. Residents can follow the debate in person at the David Hankerson Building or tune in via the county’s meeting stream if they prefer to watch from the couch.
Staff review and next steps
Under the draft, if the board signs off, county staff would be directed to comb through existing development regulations and land‑use permit requirements and then come back with proposed ordinance changes before any new data‑center permits are accepted, per WSB‑TV. The temporary ban is written to expire after 180 days, or sooner if officials complete the code updates and adopt new rules.
Part of a regional push to slow the boom
Cobb’s debate lands in the middle of a regional reconsideration of hyperscale server farms, as cities and counties across metro Atlanta pump the brakes with moratoria and tighter standards. Coverage in Georgia Trend details how neighboring jurisdictions have turned to short‑term pauses and stop‑gap measures while they try to balance the lure of new tax revenue against concerns from nearby neighborhoods.
Water and power are central concerns
Utilities and water managers warn that data centers can demand enormous volumes of water and hefty amounts of electricity, potentially stretching regional supplies and power grids to their limits. The Cobb County–Marietta Water Authority has cautioned that some facilities can consume more than a million gallons of water a day, and debates over Georgia Power’s long‑range capacity plans have become a flashpoint for policymakers, according to reporting from WSB Radio and the Cobb Courier.
Legal and local implications
If commissioners approve the temporary ban, new rezoning petitions and building permits for data‑center projects would be frozen while staff and the board hammer out updated rules. That process could include public hearings, fresh zoning language that narrows where large campuses can locate, and additional requirements focused on noise, generator emissions and water‑use reporting.
The commission is set to take up the item at its afternoon work session and revisit it during the evening meeting. If the moratorium is adopted, the county will establish a timeline for staff to return with proposed ordinance language and any follow‑on code changes.
