A county moratorium temporarily barred new data-center applications from May 7, 2025, until December 17, 2025.

In the LM Light Industrial District, data centers require conditional-use approval rather than being automatically permitted.

Data centers and data-center campuses must be located on lots of at least 25 acres.

Lots must have at least 250 feet of road frontage.

Buildings are limited to 60 feet, with up to 10 additional feet for parapets and rooftop equipment, for a maximum total height of 70 feet.

Data centers must maintain 75-foot front, 100-foot side, and 100-foot rear setbacks.

Buildings must be separated from one another by at least 100 feet.

Lot coverage may not exceed 80 percent.

Data centers must use public water and sewer service.

Applicants must hold a community meeting after filing a rezoning petition and at least 30 days before the related public hearing; the meeting must occur in Coweta County between 5 p.m. and 8 p.m. Properties in the M Industrial District are subject to this requirement when rezoning is required.

Community-meeting notice requires mailed notices to property owners within 1,000 feet at least 14 days beforehand, a newspaper advertisement at least one week beforehand, and a subject-property sign posted at least 14 days beforehand.

An applicant representative with decision-making authority over the data-center design must attend the community meeting in person.

Buildings visible from public roads or rights-of-way must use at least two specified exterior materials, including brick, stone, architectural precast concrete, non-reflective architectural metal panels, or high-quality fiber-cement panels.

In the LM District, any building wall visible from a public right-of-way must have fenestration covering at least 30 percent of the gross above-grade wall area.

Facades visible from public rights-of-way must use at least two specified mass-breaking features, such as articulation at intervals no greater than 50 feet, stepped rooflines, projections or recesses at least two feet deep, or changes in materials or colors.

Buildings adjoining residentially zoned or used property require a 300-foot buffer from the property line.

The first 100 feet of a required residential buffer must remain undisturbed and natural unless needed for approved fencing, access, or utilities; disturbed or sparsely vegetated areas must be planted under Article 25.

The facility must be enclosed by fencing; property-line fencing must be decorative metal at least eight feet high, and barbed, concertina, razor, and similar anti-climb features are prohibited there.

Before a land-disturbance permit, the applicant must conduct a preconstruction ambient-noise survey over at least 72 hours using specified sound-measurement methods, submit an impact report, and obtain approval after county review.

Noise at a residential property boundary may not persist for more than 60 seconds above five dB(A) over ambient levels from 10 p.m. to 7 a.m., or above 10 dB(A) from 7 a.m. to 10 p.m.

Backup-generator testing is limited to weekdays from 9 a.m. to 5 p.m. and is prohibited on federal holidays, except that generators exceeding the sound limits may operate during emergency power outages.

Applicants must submit an environmental impact assessment with the zoning petition addressing water resources, air quality, ecology, archaeology, and cultural or historical resources.

Exterior lighting must use full-cutoff, fully shielded fixtures with zero uplight, be mounted no higher than 20 feet, be located at least four times the mounting height from property lines, and not exceed 0.05 footcandles at residential property lines.

Applicants must set aside land for parking at a rate of one space per 2,000 square feet of gross floor area, although the final number of constructed spaces is determined through an approved parking analysis.

Before a land-disturbance permit, applicants must obtain approval of a Construction Traffic Management Plan; the county may require a surety bond, and required transportation improvements must be under construction before permanent-building permits are issued.

Operators must publish an annual report describing waste-management activities and make it publicly available.

Mechanical equipment, emergency generators, substations, and appurtenances must be screened from public rights-of-way and adjoining residential property with an at least eight-foot-high barrier providing at least 95 percent opacity.

Applicants must specify cooling and ventilation equipment in the zoning petition, and open-loop systems are prohibited for liquid cooling and ventilation.

Applicants must provide a utility-provider letter confirming preliminary coordination and that service is feasible, either with the rezoning petition or when applying for a land-disturbance permit if the property is already zoned.

Primary on-site power generation is prohibited even if the utility grid fails.

Generators are expected to meet Tier 4 Final standards and must be treated as stationary sources, while dust control must comply with Chapter 30.

Substations, which are treated as accessory uses, may not be located within 300 feet of an adjacent public road or residentially zoned property.

At least once each year, the operator must coordinate specialized emergency-response training with the county 911/EMA Director or designee and reimburse the county for the training and necessary equipment costs.

Data centers are allowed in two industrial zoning districts: as a conditional use in LM Light Industrial and as a permitted use in M Industrial, subject to the listed standards. This creates an established zoning pathway for development rather than requiring a new ordinance for each project. Data centers, subject to the following requirements Data center or data center campus, subject to the following requirements

The ordinance recognizes a data center campus as one property containing more than one data center, allowing multiple facilities to be developed on a single property. Each individual data center may contain up to 500,000 square feet of gross floor area. Data center campus contains up to 500,000 square feet gross floor area

The development envelope permits buildings up to 60 feet high, with up to 10 additional feet for parapets and rooftop equipment, and allows up to 80 percent maximum lot coverage. These limits apply subject to applicable federal, state, and local regulations and the other ordinance requirements. Maximum height Maximum lot coverage

Parking obligations are flexible: the applicant must reserve land for one space per 2,000 square feet of gross floor area, but the number of spaces actually built is determined through an applicant-submitted parking analysis approved by the Public Works Administrator. the actual number of parking spaces constructed shall be determined

The ordinance establishes a utility-availability process: an applicant may provide a utility provider's letter of intent during rezoning or with the land-disturbance permit if the property is already zoned, confirming preliminary coordination and that service is feasible subject to final engineering. letter of intent to serve the proposed project

Backup generators may be used during emergency power outages even if they exceed the ordinance's normal maximum sound levels. Routine generator testing is also expressly authorized on weekdays from 9:00 a.m. to 5:00 p.m., except federal holidays. Use of backup generators that exceed the maximum sound levels is permitted during emergency power outages
