Data Centers: Daily Notes | October 29, 2026

Hubbard Township, Ohio

Hubbard Township trustees rejected the zoning commission’s proposed data center regulations, keeping the township’s moratorium in place and sending the rules back for tighter language.

The hearing drew enough residents that it moved to the Hubbard High School auditorium. Some early speakers urged trustees to approve the regulations, but sentiment shifted after township legal counsel Patrick Wilson explained the township couldn’t keep its moratorium and adopt zoning rules at the same time. Residents then pushed trustees to reject the proposal and buy more time, with some asking for stricter rules on brownfield sites.

Pima County, Arizona

The Pima County Planning and Zoning Commission voted 8-1 on Oct. 28 to advance amendments to its data center ordinance, on the condition that county staff address monitoring, noise and water limits, and a narrow definition of a data center.

The proposal would not ban data centers but would require a Type 3 conditional use permit in the county’s most restrictive zone, CI-2 heavy industrial, which makes up about 2% of county land. It focuses on water and energy use guidelines and on transparency for future projects, shaped by nearly 2,000 survey responses and two public hearings. Commissioner Robert Cook cast the lone no vote, saying he would only support criteria strict enough that no data center could be built. A revised proposal goes to the Board of Supervisors in early December.

Arlington, Texas

Arlington staff have proposed a set of data center ordinances tailored to the types of facilities the city is most likely to see, given its limited available land.

Stand-alone data centers, such as enterprise facilities run by a single company, would be allowed only in light industrial and industrial manufacturing districts with a specific use permit, or in planned development districts when the project is specifically identified. They would need to sit at least 300 feet from homes, stay under 75 feet tall, avoid evaporative cooling, and meet daytime and nighttime noise limits with testing before and after construction. Land development assistant director Kenneth Bloom described the proposals as a work in progress, noting the technology changes constantly.

Frederick County, Maryland

A judge on Friday denied data center developer Quantum Maryland’s emergency request for a temporary restraining order against Frederick County Executive Jessica Fitzwater’s data center moratorium.

Judge James Bonifant, a retired Montgomery County judge specially assigned to the case, found that Quantum failed to clearly show it would suffer immediate, substantial, and irreparable harm before a full hearing could be held. He also declared moot several Quantum motions seeking to speed up the case and set a Nov. 10 status hearing on the company’s motion for a preliminary injunction. Quantum alleges the moratorium cost it a real estate deal near Adamstown worth at least $500 million, and it is seeking injunctive and monetary relief from the county, the planning commission, and Fitzwater. Fitzwater first paused new data center applications in July and extended the pause in September to July 1, 2027, though projects with prior Adequate Public Facilities Ordinance agreements are exempt.

The commission voted Wednesday after a public hearing that drew about 50 people, with roughly 20 addressing the five-member board. All but one speaker voiced reservations about a data center in Harmony, citing quality of life, noise, and environmental impacts, and several questioned the city’s openness about the process. Now in its sixth draft, the ordinance aims to protect public health and safety while preserving Harmony’s rural character and environmental resources. No specific data center project has been publicly announced in the city.

Glendale, Arizona

The Glendale City Council approved annexing and rezoning land at Litchfield Road and Olive Avenue for Project Eagle, a 160-acre data center about 2 miles northwest of Luke Air Force Base’s front entrance.

The $36 billion project, also known as Project Baccara, is expected to include two data center buildings and about 700 megawatts of natural gas generators to power the site and support the regional grid, according to project information from the City of Surprise. Before work begins, the developer must help pay for a new traffic signal and enter an agreement to fund specialized hazardous materials and fire services. Construction is scheduled to start next month, with the first building set to open in 2028.

Natrona County, Wyoming

The Falls Ranch data center project in Natrona County will continue under a new development partner after Prometheus Hyperscale abruptly abandoned its proposal.

Prometheus had pitched the 1.5-gigawatt campus as a source of 3,000 temporary construction jobs and 150 permanent positions, with power from on-site natural gas generators. The plan drew pushback from neighbors along Hat Six Road and Meadow Acres, who raised concerns about generator noise, light pollution, air emissions, truck traffic, and state sales tax exemptions for data center equipment. Falls Ranch said it will still pursue local filing deadlines and community partnerships, with public meetings expected in 2027.

Jefferson County, Georgia

The Jefferson County Commission passed a technology zoning ordinance covering data centers at its Wednesday meeting, despite opposition from many residents who said the rules don’t do enough to protect neighbors.

The county administrator said data center developers have contacted some landowners, but no official applications have been filed. Because no land is currently zoned for the new technology district, any data center would need to go through the full rezoning process, including multiple public meetings. Residents who spoke cited the county’s agricultural and rural character and said the ordinance moved forward too quickly without enough public input, while some commissioners pointed to a declining workforce and rising taxes as reasons to seek new revenue.
