📜 Data center rules

Board of Aldermen passed Board Bill 49 unanimously on Sept. 11, 2026, and Mayor Cara Spencer signed it on Sept. 17. It sorts data centers by size, keeps them out of homes areas, sets distance rules, bans water-heavy cooling and requires more renewable power over time.

✅ Approved

Board of Public Service unanimously approved a conditional use permit for the data center near the Armory. In July the Board of Adjustment let it go ahead with added rules, including 50% renewable power within 5 years, closed-loop cooling, and no diesel generator testing on bad air days.

📌 Other

City leaders chose not to pause data centers. Instead Mayor Cara Spencer ordered staff to write data center rules within about five months, with public hearings required for every data center before a permit.
