Seattle Council adopts one-year moratorium on new AI/data centers after heavy public comment
Summary
The Seattle City Council passed Council Bill 12124 in a 9-0 vote, imposing a one-year moratorium on acceptance, processing or approval of new or expanded AI/hyperscale data centers while the city studies grid, water, rate and land-use impacts. The move follows weeks of public testimony and a companion resolution ordering a citywide study.
Councilmember Lin’s land-use ordinance to pause new and expanded AI data centers in Seattle passed unanimously, 9-0, after hours of public comment and committee hearings.
The one-year moratorium, adopted as Council Bill 12124, halts the acceptance, processing or approval of applications for the establishment or expansion of data centers while city departments review impacts on electrical grid capacity, water usage, utility rates, land use, employment patterns and public health. Councilmember Juarez’s companion Resolution 32204 asks departments to coordinate on a comprehensive study and report back to Council.
Why it matters: Residents, union members and former tech employees told the Council the rapid buildout of hyperscale facilities risks large water consumption, pressure on the electric grid, higher utility rates for residents and concentrated economic benefits for corporate owners rather than local communities. Ben Jones, digital and communications director for a community group, told the Council organizers had delivered “over 98,000 messages endorsed by over 50 community organizations” urging action.
Voices from the meeting: Darius, a software engineer and member of Amazon Employees for Justice, told the Council: “Big tech needs data centers more than we do,” arguing the city should demand renewable energy sourcing and stronger oversight of corporate practices. Councilmember Juarez, summarizing committee findings and public concern, said, “If I could, today, I know if I could actually do this today, I would do a complete stop of A.I. data centers,” reflecting the breadth of concern heard in public comment.
What the ordinance does: The moratorium creates time for staff to develop data and regulatory options; Councilmembers repeatedly emphasized the need to coordinate with Seattle City Light and regional partners to understand capacity constraints and mitigation paths. Councilmember Kettle’s amendment clarified that the study should consider both hyperscale and smaller, locally serving data centers (including those that support hospitals and first responders) so policymakers can distinguish differing impacts.
Process and next steps: The Council passed the moratorium after committee work and public hearings. City departments were directed to carry out the study requested by Resolution 32204 and to report findings to the Council. The ordinance takes effect immediately under the Council’s vote; staff and council offices said they will return with details of the review work program.
