Why It Matters
Maryland counties are moving to restrict or halt data center development as communities voice concerns about industrial sprawl, infrastructure strain, and environmental impact. The movement reflects broader tension between economic development incentives and local quality-of-life priorities across the state.
What Happened
Harford County became the first jurisdiction in Maryland to enact a complete ban on data center facilities after county research determined it lacked the electrical infrastructure necessary to support hyperscale operations. The decision followed grassroots organizing by residents like Bryan Cornell, who learned in April that a golf course behind his family’s farm was under consideration for a data center campus. Cornell and Krissy Flatau founded Our Land, Our Home, Our Harford, a community opposition group that helped mobilize support for the ban.
The restrictions extend well beyond Harford. Thirteen counties have enacted temporary moratoriums on data center development, with two additional counties voting on similar pauses in recent weeks. Montgomery County, the state’s most populous jurisdiction, extended its data center pause from six months to 18 months following a compromise between council members who favored a shorter freeze and those seeking a two-year halt. County Executive Marc Elrich signed an executive order in June approving the extended pause.
Frederick County implemented its own pause on new data center permits through year-end after County Executive Jessica Fitzwater signed an order July 1. The move came as tensions escalated over the county’s industrial zoning. In December, the Frederick County Council voted to expand data center zoning around the Quantum Frederick project to roughly 2,600 acres—about 1,000 acres more than the county planning commission had recommended. The expansion prompted residents to pursue a ballot referendum, collecting more than 20,000 signatures in opposition.
Caroline County also paused data center development. A coalition called Marylanders for Data Center Reform, comprising 62 environmental and community organizations, has coordinated messaging across the state in opposition to rapid hyperscale facility expansion.
By the Numbers
13 — counties with temporary data center moratoriums in place
62 — member organizations in the Marylanders for Data Center Reform coalition
2,100 acres — land purchased by developers in Frederick County in 2021 for a proposed hyperscale data center campus
2,600 acres — expanded data center zoning area approved by Frederick County Council in December
20,000+ — signatures collected by Frederick County residents for a ballot referendum opposing zoning expansion
Zoom Out
Data center development has accelerated nationally as artificial intelligence, cloud computing, and digital infrastructure demand surge. States and counties face competing pressures: the promise of tax revenue, job creation, and technological investment against concerns about power consumption, water usage, electromagnetic fields, and industrial transformation of rural and suburban communities. Maryland’s moratorium wave reflects a pattern emerging in other states where communities seek time to assess impacts and develop regulatory frameworks before granting large-scale approvals.
Fitzwater created a data center work group in June 2023, signaling early county-level attention to the issue. The pause orders give jurisdictions time to study infrastructure capacity, environmental effects, and zoning adequacy before deciding whether to permit new facilities.
What’s Next
Frederick County’s moratorium expires at year-end, setting a near-term deadline for the county to decide whether to extend the pause, approve new projects, or establish permanent regulatory changes. Montgomery County’s 18-month extension buys time through early 2028. Harford County’s complete ban will likely face legal or political challenges if developers seek variances or zoning changes. The outcome in Maryland could influence data center policy discussions in neighboring states as communities nationwide grapple with balancing digital infrastructure expansion and local land-use priorities.
