Seattle Committee Holds Public Hearing on Data Center Moratorium, Environmental Appeals Bill
The Seattle Land Use and Sustainability Committee held a public hearing on a data center moratorium and Council Bill 121215, which proposes to remove administrative appeals for legislative SEPA decisions. Public comment saw significant opposition to CB 121215, with citizens expressing concerns over losing the right to challenge environmental impacts, including those from data centers, and highlighting issues like increased heat islands, pollution, and electricity/water usage. Proponents argued the bill would streamline housing development without weakening environmental protections. The discussion included specific concerns about a Digital Realty data center and the broader implications for climate goals and environmental justice.
The Seattle Land Use and Sustainability Committee convened on July 15, 2026, for a public hearing addressing a proposed data center moratorium (Ordinance 127447) and Council Bill 121215. The latter seeks to exempt legislative State Environmental Policy Act (SEPA) decisions from administrative appeal, a move discussed in the context of streamlining Seattle's land use processes, particularly for housing development.
During the public comment period, substantial opposition emerged against Council Bill 121215. Speaker Dave Gallagher strongly opposed the bill, arguing it would strip citizens' rights to challenge environmental issues, including flawed applications for data centers that might contain incorrect electricity and water usage estimates. Other residents and advocacy groups like Tree Action Seattle, Washington Physicians for Social Responsibility, and the Laurelhurst Community Council echoed concerns that removing appeal mechanisms would silence public voices, jeopardize environmental protections, and disproportionately affect environmental justice communities through increased heat islands, pollution, and tree canopy loss. They urged for a substitute bill that reforms rather than eliminates the appeal process.
Proponents of CB 121215, including representatives from Washington State NAIOP and Habitat for Humanity Seattle King and Kittitas Counties, argued that the bill is a procedural correction aligning Seattle with other regional cities like King County, Bellevue, Tacoma, Everett, and Vancouver. They emphasized that the bill would improve the predictability and efficiency of land use processes, reduce delays and costs, and help meet state-mandated housing deadlines without weakening environmental standards. Patrick Taylor, speaking as a member of the Seattle Planning Commission, also supported the bill, asserting that current appeal processes are subverted by a small group, delaying needed housing and sustainable urban growth.
The specific data center moratorium hearing addressed concerns about environmental impacts. Juliana Bernardo, an environmental justice advocate, voiced worries about new data centers in South Seattle and Tukwila exacerbating heat islands and pollution in predominantly communities of color, urging for full public disclosure requirements during permitting. Jeff Sloane suggested strategically locating data centers near existing district heating systems, such as the Seattle Center Steam Plant, to decarbonize and save the city money. Caroline Russell, a climate justice activist, expressed deep concern over data center expansion and AI's impact, stressing the need for data centers to pay for new renewable energy and associated grid costs, rather than depleting Seattle's existing green hydro resources. The discussion also referenced an application by Digital Realty for a "massive data center at 301 Virginia" with an "incomplete FIFA checklist" and "waived design review" as an example of potential environmental issues.
