Cedar City residents packed an informational hearing this week, lining up to challenge county officials over a proposed AI data center campus west of town. Neighbors warned that the massive project could remake their quiet desert skies, strain already scarce water supplies and drop a large on-site power plant into a stretch of land that has seen little heavy industry.
Roughly 110 people showed up for the Iron County Planning Commission meeting, and planners say they received about 37 pages of written comments in the two weeks before the hearing, according to FOX13. Opponents raised concerns about air quality, night lighting, electricity demand, and the project’s overall water footprint.
What the Plan Would Look Like
The conditional-use filing from Pronghorn Development describes a master-planned Antelope Data Center campus on about 640 acres along Antelope Springs Road. The plans call for five large server buildings and an on-site data center power plant that could scale up to 1.5 gigawatts at full buildout, according to the county’s public-notice entry on the state site. The March 5 meeting was informational only, giving planners time to gather public input and request follow-up materials before any recommendation goes to the full county commission, per Utah Public Notice.
Water, and a Puzzle of Numbers
Planning materials reviewed by KSL list a one-time fill of about 2.6 million gallons, roughly 8 acre-feet, with estimated annual use near 3.13 acre-feet. The developer says most cooling water would be recycled on-site. Neighbors pressed planners for clear answers on how that reuse would be monitored and what kind of reporting or penalties would apply if actual consumption overshoots the projections.
How Planners Can Respond
"The planning commission can require metering of all water usage and require that it be reported," Iron County planner Brett Hamilton told KSL. The same coverage noted that tax and economic arguments often carry weight with local officials, a tension many residents said does not erase concerns about long-term environmental tradeoffs.
Statewide Scrutiny
The local fight is unfolding as the Utah Legislature moves to require large data centers to disclose their water usage before construction and on an ongoing basis. The requirement is part of a broader package of bills aimed at protecting the Great Salt Lake and the state’s limited water supply, according to Deseret News. Those new reporting rules are already shaping how both developers and county officials talk about monitoring and enforcement.
Economic Tradeoffs for a Small County
County leaders acknowledged that recent layoffs have added pressure to attract new employers. FOX13 reported that Genpak plans to close its Cedar City plant this spring, affecting about 200 workers. Supporters of the data center project argue it could bring long-term tax revenue and contracting work, while residents counter that the promised safeguards still leave big questions about water, air, and light pollution decades into the future.
The application remains under review. The planning commission can attach conditions or send a recommendation to the full county commission for final action, according to Utah Public Notice. Meeting materials, agendas, and contact information for the Iron County Building and Zoning Department are available on the same state public-notice page.
