The San Mateo County Board of Supervisors approved an initial plan to assess potential zoning restrictions on data center construction in the county’s unincorporated areas. The review is intended to determine what rules would best serve local communities, residents and the economy.

Supervisor Lisa Gauthier, who sponsored the resolution, said the action was an initial step rather than a final regulatory decision. Supervisors’ concerns include data centers’ water consumption, energy demand and emissions, and the county has not yet adopted specific restrictions.
