Anne Arundel Data Center Ban Highlights Federal Commitment to Growth

Executive Summary

A Maryland county legislator is pushing to ban new data centers in Anne Arundel County, putting local land-use authority on a direct collision course with federal infrastructure priorities that show no signs of slowing. The proposal, championed by Legislator Nathan Volke, reflects a growing pattern of community-level resistance to large-scale digital infrastructure—but federal development programs operate under a separate legal and funding framework that local ordinances cannot easily reach. Private developers aligned with federal initiatives stand to benefit, while local and regional investors in speculative data center land plays face a new layer of permitting risk. The InfraSale read: regulatory fragmentation is accelerating, and site selection discipline now requires a two-track analysis of both municipal and federal policy trajectories.

What Happened

Legislator Nathan Volke has introduced a proposal to ban new data centers in Anne Arundel County, Maryland. The move is a direct response to local concerns about the proliferation of large digital infrastructure facilities—concerns that typically center on noise, power consumption, traffic, and the displacement of other land uses.

The proposal places Anne Arundel in a growing cohort of jurisdictions pushing back against data center growth, even as regional demand for computing capacity continues to climb. The Virginia suburbs of Washington, D.C., remain the largest data center market in the world, and Maryland counties sit in the shadow of that demand curve.

Critically, Volke's proposal does not—and legally cannot—constrain federal government construction activity. The federal government retains authority to site and develop its own infrastructure facilities, meaning any ban that passes would apply unevenly across the county's development landscape.

Why This Matters

Local bans rarely exist in isolation. When a county moves to restrict data center development, it sends a signal to the broader market—one that raises the risk premium on nearby sites and accelerates capital flight to more permissive jurisdictions. Adjacent Maryland counties and across-the-line Virginia markets absorb that displaced demand, often without the infrastructure to handle it cleanly.

The federal carve-out embedded in this situation is the more structurally significant detail. If federal data center activity continues to expand in the region regardless of what Anne Arundel's council enacts, the ban effectively creates a two-tiered development environment: federally backed projects proceed, while private developers are locked out. That asymmetry distorts competition and leaves private capital holding the regulatory risk.

Industry context: The Washington-Baltimore corridor has seen sustained federal data center investment tied to defense, intelligence, and civilian agency modernization programs. That pipeline is driven by congressional appropriations and executive branch mandates—neither of which are subject to county zoning authority.

For investors, the more immediate concern is underwriting certainty. A pending ban, even before passage, clouds title searches, delays financing, and introduces legal exposure that most institutional lenders will not accept without a clear resolution.

Power & Interconnection Impact

Anne Arundel sits within the PJM Interconnection footprint, the largest competitive wholesale electricity market in North America. Data centers are among the most power-intensive facilities in the commercial real estate sector, and any significant shift in the county's development posture—whether a ban passes or not—will affect how PJM and the local utility model load growth in the subregion.

If private data center development is curtailed locally, interconnection queue positions associated with those projects lose value rapidly. Developers who have invested in queue position, transmission studies, or substation upgrades in anticipation of county-level approvals face stranded costs.

Assumption: Federal facilities typically negotiate power delivery directly with utilities under separate service agreements and may have priority access to grid infrastructure that private developers do not. If federal data center load continues to grow in the county regardless of the ban, the net effect on substation capacity and transmission constraints may be limited—but the private sector's ability to access that capacity will be further restricted.

Land, Zoning & Permitting Impact

A formal ban, if enacted, would likely trigger an amendment to Anne Arundel's zoning code that explicitly excludes data centers as a permitted or conditional use in all or most zones. That change would make existing entitled data center sites substantially more valuable—those parcels would hold a non-conforming or grandfathered status that new entrants cannot replicate.

For landowners currently marketing sites as data center-suitable, the proposal creates a narrow window. Sites that can secure entitlements before a ban takes effect could command a significant premium. Sites without active applications in process face an abrupt repricing.

Permitting timelines, already one of the primary friction points in data center development, would extend further in a ban scenario—not just because of the formal prohibition, but because of the legal uncertainty that surrounds any major zoning change. Environmental review, community input processes, and potential litigation all add months to any project already in the pipeline.

Industry context: Several counties in Virginia and Texas have also experimented with data center moratoria or use restrictions in recent years. In most cases, the legislative process itself—not the final outcome—was sufficient to pause private investment for 12 to 24 months.

Investment Takeaway

Existing entitled sites gain scarcity value. If the ban passes, parcels with active permits or vested rights become rare assets in a supply-constrained market. Owners should document entitlement status immediately.
Speculative land plays in Anne Arundel carry elevated near-term risk. Underwriting assumptions built on a permissive zoning environment need to be stress-tested against a ban scenario before any capital is committed.
Federal adjacency is a hedge, not a guarantee. Proximity to federal data center activity may sustain local power and fiber infrastructure, but it does not protect private developers from local use restrictions.
Displaced demand flows to adjacent markets. Prince George's County, Howard County, and northern Virginia are the most likely beneficiaries of capital repositioning if Anne Arundel closes its door to private data center development.
Monitor the legislative timeline aggressively. The gap between proposal and enactment is the highest-optionality period for developers who can move quickly on entitlements or acquisitions.

InfraSale Market Angle

For investors actively sourcing data center sites in the Mid-Atlantic, the Anne Arundel situation is a live case study in permitting risk materializing at the county level. The proposal has not yet passed, which means the market has not fully priced the downside—or the upside in adjacent jurisdictions. Investors who track legislative calendars at the county level, not just state policy, are positioned to act before consensus repricing occurs.

The federal carve-out also presents a specific opportunity: developers who can structure projects with federal agency involvement—as tenants, partners, or end-users—may find a path to development even if private commercial data centers are prohibited. That is a structurally different underwriting conversation than a standard merchant data center deal.

Landowners in Anne Arundel with sites that have any existing commercial or industrial entitlements should be actively engaging with legal counsel and brokers now, not after the ban is enacted. The window is open; it will not remain so indefinitely.

FAQ

How will the data center ban affect local investment?

A ban would directly increase risk for developers and landowners holding unentitled data center sites in Anne Arundel. Capital that had been allocated to the county will likely reprice and redirect to adjacent jurisdictions with more permissive zoning, reducing local deal flow and compressing land values for sites that no longer qualify for data center use.

What are the implications of local vs. federal policies on data center development?

When local and federal policies point in opposite directions, the result is regulatory fragmentation—a condition where different categories of developers face materially different risk profiles on the same geography. Private capital bears the full weight of local restrictions while federally backed projects proceed unimpeded, which distorts market competition and creates underwriting complexity for institutional investors.

Will federal plans override local bans on data centers?

Federal construction programs are generally not subject to local zoning ordinances, meaning a county-level ban would not stop federal agencies from siting or expanding data center facilities within Anne Arundel. However, private developers cannot claim that federal exemption, and the ban would apply in full to commercial projects without a federal nexus.

What happens to sites that are already in the permitting pipeline?

Sites with active applications or vested development rights at the time a ban is enacted typically receive some form of grandfathered status, though the specifics depend on how the ordinance is drafted. Those sites become scarce assets in a restricted market—but developers should not assume grandfathering is automatic and should seek legal counsel immediately.

Which markets benefit most if Anne Arundel restricts data center development?

Industry context: The most likely beneficiaries are jurisdictions with existing power infrastructure, fiber connectivity, and permissive zoning within the same demand corridor—primarily Prince George's County, Howard County, and northern Virginia markets. These areas are already under capacity pressure; a formal ban in Anne Arundel would accelerate that pressure and likely move land values in those markets higher.
