Know the Facts · A Citizen's Guide
Birmingham can set strong, clear rules for the largest facilities and still welcome the industry. These are the changes that protect the people who already live here - and the proof that they will not cost the city a single data center.
The strongest data center markets in America run on public review and real standards. The rules did not scare the industry off. They kept it honest. Be at the public hearing at Birmingham City Hall, Tuesday, June 9th, 9:00 am.
First, the Worry
No. The places with the strictest review are the places with the most facilities. Strong rules have not driven the industry away. They have helped communities welcome it on fair terms.
Loudoun County, Virginia is the largest data center market in the world. It moved data centers to project-specific Special Exception review in 2025 - and is still number one.
Google's Mesa, Arizona data center, approved in 2019. Mesa keeps drawing hyperscalers, and in 2025 it adopted rules requiring city council approval of new data centers.
Data centers across Georgia, a booming Southeastern market, where some counties still require 1,000 feet from existing homes.
The Fixes
The pattern is consistent. Loudoun, Fairfax, and Prince William in Virginia, Calvert County in Maryland, and Chandler and Mesa in Arizona all tightened their rules and kept attracting investment. Each fix below shifts a cost or a risk back onto the company instead of the community. None would stop a responsible facility from being built here.
A Special Exception is a public hearing on the actual project, where the company must prove its case and the board can attach conditions, require changes, or deny it. The draft trades that review for an administrative checklist. The city can adopt these rules in public and still keep project-by-project review.
Model: Loudoun County, VA · moved to Special Exception, 2025The draft requires a noise study but sets no number to measure against, and nothing for the low-frequency hum residents find hardest to live with. A study cannot prove compliance with a limit that does not exist.
Model: Loudoun 55 dB · Prince William 44 dBSetbacks run only from residential zoning, so a school, a hospital, the animal shelter, and programs serving children and adults with disabilities get no protection. Distance should be a floor beneath public review, never a substitute for it.
Model: Fairfax 200/300 ft · Jackson County, GA 1,000 ftThe draft requires no analysis of where the facility's waste heat and air go, even though field research shows large facilities can measurably warm the air nearby. Without a study, no one can evaluate the local impact before approval.
Gap: no thermal review requiredThe draft permits fuel cells as a routine power source in the administrative pathway - with no cap and no fuel limit - while restricting other fossil-fuel generation to emergencies. The city should resolve how a large on-site power source is treated before adoption.
Gap: uncapped on-site powerThe draft only asks the applicant to note rate impacts. It should require the facility to pay for its own grid upgrades and show it will not shift those costs onto households.
Model: Alabama SB 270 · large-load cost rulesThe studies come from the applicant or its hired consultants. For a project this size, independent acoustical, thermal, and utility review ensures the public and the council see unbiased information. Good rules rely on verification, not trust.
Principle: verify, do not assumeThe draft has one post-construction study, no ongoing monitoring, and nothing requiring removal of the facility at the end of its life. This same ordinance already requires reclamation bonds for mining and timbering. It simply left that protection out here.
Precedent: the ordinance's own mining bondsSide by Side
City staff called the ordinance modeled on Loudoun - the gold standard. On the points that matter most, the draft asks for less than the models do.
| Protection | Birmingham draft | Loudoun County, VA | Fairfax County, VA |
|---|---|---|---|
| Project-specific review (Special Exception) | Removed for the largest facilities; replaced with an administrative checklist | Required: Special Exception hearing and board vote on the project | Special Exception in practice for most projects |
| Numeric noise limit | None set in the section | 55 dB at residential line, tightening for low-frequency | Tied to the County Noise Ordinance |
| Setback from homes | 500 ft in some zones; none fixed in heavy industrial | Setbacks plus berm and buffers | 200 ft buildings, 300 ft equipment |
| Independent review | Not required | Board can require it | Board can require it |
| Decommissioning bond | None | Under Phase 2 review | Not specified |
A Special Exception is a public hearing on the specific project, not the hearing on the ordinance itself. The city can adopt these rules in public and still keep the project-by-project review. In the model jurisdictions a setback is also a floor set through that project review - so a larger distance approved by checklist is weaker than a smaller distance reviewed in public.
