Birmingham approves 20-condition zoning rules for data centers
Birmingham City Council approved a zoning ordinance June 9 establishing 20 conditions for hyperscale and other data-center development inside the city.
The rules set requirements for where large data centers can be built and how proposed facilities must address water, electricity, noise, screening, utilities and public notice. The ordinance gives Birmingham a local framework for an industry that can require substantial land, power and cooling infrastructure.
Eligible sites must contain at least 5 acres. A data center must also be set back 500 feet from residential or urban neighborhood districts and separated by 1,000 feet from high-capacity transit facilities.
Water and power requirements
The ordinance places a specific limit on cooling systems. Facilities must use closed-loop cooling, with water consumption no greater than that of a similarly sized office building.
The rules also prohibit on-site gas-turbine power and 24/7 diesel-generator power. Solar power, fuel cells and battery storage are addressed separately under the ordinance.
Applicants must provide projections for the facility’s electrical demand. That requirement gives city officials information about the expected load before a project moves through the development process, although the ordinance announcement does not identify a citywide cap on data-center electricity use.
Notice and public response
Developers must notify property owners within 500 feet by certified mail. The ordinance also includes conditions covering noise, landscaping, utilities and other community-protection measures.
The City of Birmingham described the measure as establishing 20 community protections. The Alabama Reflector reported that the council acted after a public hearing and approved the ordinance by a 6-3 vote.
The measure drew criticism during the approval process. The Alabama Reflector reported concerns from residents and environmental groups, including objections related to the removal of special-exception requirements for compliant hyperscale data centers.
That distinction matters because the ordinance establishes conditions for qualifying development rather than banning data centers across Birmingham. A project would still have to meet the new site, setback, cooling, power, notification and other requirements, but the city’s announcement does not say that the rules eliminate future construction.
What the ordinance means for Birmingham
The new standards place neighborhood distance, water consumption and energy demand at the center of the city’s approach to data-center growth. The 5-acre minimum and large separation distances could affect which parcels are eligible, while the cooling and power provisions address infrastructure concerns that can extend beyond a project’s property line.
For nearby property owners, the certified-mail requirement creates a defined notice area around a proposed facility. For the city, electrical-demand projections and the limits on certain on-site power systems provide information and operating restrictions as officials evaluate development proposals.
The council’s approval is the central action announced June 9. The City of Birmingham announcement does not state the ordinance number or an effective date.
