Seattle council moves to ban AI data centers

The Seattle City Council voted 9-0 on June 9 to impose a one-year emergency moratorium on new large data centers inside city limits, moving one of the country’s largest tech hubs to slow AI-linked infrastructure growth while the city studies the effects on power, water and land use. The ordinance applies to facilities with electrical capacity above 20 megavolt-amperes and requiring uninterruptible power, according to the council. The action followed weeks of public testimony and city warnings after four companies approached Seattle City Light about building five large-scale facilities. Those projects would have had a combined maximum demand of 369 megawatts, or about enough electricity to power 300,000 homes, the council said. ### Why did Seattle move before any of the projects were built? April reports that four companies had approached Seattle City Light about five large-scale data centers triggered the city’s response. Mayor Katie B. Wilson said on April 18 that her administration was exploring long-term policy options, including a moratorium, because of concerns about utility costs, community health, pollution and equity. (council.seattle.gov) On April 30, Councilmember Debora Juarez, Councilmember Eddie Lin and Council President Joy Hollingsworth said they would introduce emergency legislation paired with a resolution ordering impact studies. The council said those studies would examine effects on electrical grid capacity, water usage, utility rates, land use, jobs and public health. (wilson.seattle.gov) ### Which facilities does the moratorium actually cover? The June 9 ordinance defines covered data centers as facilities used primarily for storing and processing digital data, with power capacity over 20 megavolt-amperes and a need for uninterruptible power. GeekWire reported that threshold is enough power for thousands of homes, and KUOW reported the measure was drafted to pause the kind of large warehouse-style projects proposed in Seattle’s industrial areas. (council.seattle.gov) Existing smaller or specialized facilities were not the main target. Councilmember Eddie Lin said the city already hosts co-location and mission-critical facilities that support 911 call centers, municipal functions, hospitals, universities and cancer research, and the council said those essential services could continue while the city develops safeguards around larger projects. KUOW also reported the legislation was amended to allow existing data centers to expand. (council.seattle.gov) ### What were council members and residents worried about? Eddie Lin said large AI data centers around the country were driving up utility costs for residents and small businesses while creating air, water and noise pollution. Joy Hollingsworth said the moratorium was intended to give the city time to do “homework” before making long-term decisions affecting infrastructure, utility rates, water usage and sustainability goals. (council.seattle.gov) Public opposition was broad and visible. GeekWire reported that more than 50 people testified at the June 9 meeting and none spoke in favor of the projects, while council members said they had received more than 98,000 emails on the issue. KUOW reported the Land Use and Sustainability Committee had unanimously advanced the bill on June 3 after public comment in support of a pause. (council.seattle.gov) ### Did anyone frame this as a broader fight over AI infrastructure? Debora Juarez linked the vote directly to AI and data-center growth. “This is Seattle’s position on AI and data centers,” Juarez said at the June 9 meeting, according to GeekWire. Lin said the city should not subsidize “record profits of large corporations from the AI boom,” according to the council’s release. (geekwire.com) Industry and labor voices appeared in the debate, though not always in the same way. KUOW reported that a trade-group representative had highlighted tax revenue and jobs at an earlier meeting, while members of Amazon Employees for Climate Justice urged the council to demand public benefits, renewable energy commitments and labor protections if large projects are ever allowed again. (geekwire.com) ### What happens next after the council vote? Mayor Katie B. Wilson said on June 9 that she looked forward to signing the moratorium into law. The accompanying Resolution 32204 directs city departments and the mayor’s office to complete impact studies and build a policy framework for handling future proposals. (kuow.org) The moratorium lasts one year and can be extended for six months if needed, according to the council. Over that period, Seattle officials are expected to evaluate grid capacity, water use, utility rates, land use, jobs and public-health effects before deciding whether to write permanent regulations for any future large data center proposals.
