Anne Arundel County Data Center Moratorium Explained

Anne Arundel County's Council has unanimously approved a 15-month moratorium on data center development, opting for a temporary pause rather than an outright ban. The measure allows projects already in the pipeline, expansions of existing facilities, and certain adjacent-lot expansions to continue without interruption. A new work study group will examine regulatory approaches from other jurisdictions and recommend permanent legislation before the moratorium expires.

The decision is narrower than an initial proposal by Council member Nathan Volke, which would have removed all county code provisions governing data centers. Opposition from advocates associated with Fort George G. Meade, a major regional employer, influenced the debate by highlighting economic and national security implications.

This action by Anne Arundel County is part of a broader trend in Maryland. Montgomery County's council previously approved an 18-month moratorium with additional safeguards and a zoning measure prohibiting hyperscale data centers during the pause. Similarly, Calvert County adopted a six-month moratorium on data-center site-plan approvals, halting new applications.

The study group in Anne Arundel will also consider larger electricity-planning issues, as data center development is identified by Maryland's Public Service Commission as a factor affecting the state's electricity grid. The county's pause aims to address local questions regarding transmission, substations, water, noise, and land use, with the goal of balancing economic importance with residents' environmental and land-use concerns.
