Navigating Maryland's Evolving Data Center Zoning and Forest Conservation Mandates

The state-level action formalizes a pattern already visible across Maryland counties, where bans, development pauses, and new zoning restrictions have appeared in response to data center proposals.

County-Level Action and State Overlay

According to WMAR 2 News Baltimore, jurisdictions across Maryland have taken divergent approaches: outright prohibition of data center uses, temporary moratoriums on new applications, and conditional overlay zoning with operational restrictions. The governor's guardrails target large facilities specifically and are paired with legislative effort to terminate the existing tax break for the sector. For any county weighing a data center application or text amendment, the state's pending framework will set the outer envelope of permissible conditions.

Forest Conservation Mandate: Charles County as Working Example

House Bill 723 and Senate Bill 526 require every Maryland jurisdiction to update its forest conservation rules by July 1, 2026. The Southern Maryland Chronicle details Charles County's current draft, which illustrates the compliance work facing Somerset County planners:

• The legacy split conservation threshold — different replacement expectations for commercial versus residential projects — is removed. The default becomes a flat one-to-one ratio: one acre planted per acre cleared.
• Off-site mitigation through conservation bank credits is capped at 50 percent of the requirement. A separate Maryland Department of Natural Resources public comment process could raise that cap to 60 percent.
• The "priority forest" designation expands to include forest-interior-dwelling species habitat, tier two and three watersheds, and urban forests, layered onto existing categories of wetlands, stream buffers, and steep slopes.

Charles County planning staff told the Planning Commission that no county-wide baseline forest acreage has been established. DNR is compiling the figure, likely from aerial photography. Jurisdictions that fall short across two consecutive two-year review cycles will receive notice and have a 90-day window to cure the deficiency. The Charles County draft also relocates its fee-in-lieu program — unchanged for over two decades — from ordinance text into a regularly revised fee schedule.

Compliance Checklist for Somerset County Applicants and Residents

Somerset County is bound by the same July 1, 2026 forest conservation deadline and the same statewide data center framework now under gubernatorial development. Practical verification points:

• Confirm whether the Somerset County Planning Commission has scheduled a forest conservation ordinance hearing and identify the replacement ratio proposed in any local draft.
• Determine whether the county maintains, or has access to, a tree-planting bank or off-site conservation bank. Charles County staff noted the absence of local tree-planting banks forces reliance on conservation credits or fee-in-lieu payment.
• Review the Somerset County zoning map and pending text amendments for data center use classifications, moratoriums, conditional use overlays, and setback requirements affecting utility-scale development.
• Verify the current fee-in-lieu schedule and whether the local draft adopts the Charles County structural model — moving the fee out of ordinance text into a revisable fee schedule.
