San Jose Residents Demand Temporary Moratorium as Officials Present Draft Data Center Development Standards

San Jose municipal officials presented draft data center development standards during a contentious community hearing at City Hall on Thursday, October 15, drawing dozens of residents and environmental advocates who demanded a temporary moratorium on new server facilities. Public testimony stretched for nearly two hours inside the East Santa Clara Street chambers as speakers urged the City Council to halt approvals until enforceable environmental safeguards are finalized in December. Deputy City Manager Manuel Pineda confirmed during the briefing that two commercial data center projects remain slated for approval before the new standards take effect.

Under the planning department's proposed regulatory framework, new server complexes in San Jose must utilize recycled municipal water or closed-loop cooling architectures rather than open-loop systems that consume millions of gallons of water annually. Despite those water conservation rules, climate organizers argued that the draft guidelines fail to protect surrounding neighborhoods from industrial impacts. Dashiel Leeds, conservation coordinator for the Sierra Club Loma Prieta Chapter, testified that the standards do not cover the urban heat island effect or low-frequency infrasound and still allow backup diesel generators to pollute with nitrous oxide.

Environmental justice advocates across Santa Clara County and neighboring Alameda and Contra Costa counties pointed to similar data center zoning debates unfolding in San Francisco and the Tri-Valley. Linda Hutchins-Knowles, co-founder of Mothers Out Front Silicon Valley, said the draft standards rely on weak language like encourage and monitor while lacking real enforcement teeth. Speakers warned that approving two additional energy-intensive server campuses ahead of the December council vote undermines public trust in the municipal climate program.

Planning commissioners and utility analysts noted that staff will compile community feedback from the October hearing to revise the ordinance language over the coming six weeks. City Council committee members indicated they will evaluate stricter acoustic buffering requirements, clean microgrid backup alternatives, and binding air quality monitoring rules before the final December legislative session. Regional air quality district officials are also coordinating with municipal planners to assess cumulative emissions across South Bay industrial corridors.
