Planning staff briefs commission on data‑center policy options as jurisdictions weigh moratoria and standards
Summary
Staff told the Planning Commission that data centers range from small municipal server rooms to hyperscalers and proposed tools — conditional use permitting, caps on megawatts, noise studies, closed‑loop cooling and technology overlay zones — while commissioners discussed moratoria and site visits.
Planning Department staff provided an extended briefing on data centers in new business on Aug. 12, presenting definitions, scale, and a menu of regulatory tools while urging a measured approach paired with regional coordination.
Zoning staff said there is no single industry definition: facilities range from small municipal server rooms and colocation facilities to hyperscalers that could demand 100 megawatts or more. Staff noted key impacts to weigh: continuous noise from cooling equipment and generator testing, high electricity demand, and potential water use by cooling systems. "One of the major impacts of concern for data centers is energy," staff said, adding jurisdictions can consider caps on installed megawatts, limits on generator testing hours, sound‑modeling requirements and mandatory closed‑loop or recycled water cooling systems.
Commissioners recommended several next steps: (1) require a conditional use permit or similar discretionary review for most data‑center types so impacts can be evaluated site‑specificly, (2) sort uses by scale (measured by megawatts, square footage, noise and water) and apply zoning place‑type guidance, (3) consider a temporary moratorium while an ordinance is developed, and (4) organize site visits to example facilities. One commissioner urged staff to brief the public on draft rules and allow a comment period rather than presenting a finished regulation for a quick vote.
Staff said it is coordinating with the Weldon Cooper Center and the HRPDC and will produce draft ordinance language and potential thresholds for commission review. The commission did not vote on a policy change during the briefing; staff recommended further study and possible Council referral for code amendments.
What happens next: Staff will continue research, meet with regional partners and return with draft regulatory language; commissioners signaled support for discretionary review and potential temporary limits while work proceeds.
