California Cities Vote to Block Data Centers as AI Drives Demand

Local resistance grows to AI infrastructure

California communities are increasingly rejecting data center projects in their jurisdictions, even as artificial intelligence companies push to build the infrastructure needed to power their systems. The tension highlights a growing conflict between the state's technology ambitions and local concerns about environmental impact and resource consumption.

In June 2026, Monterey Park voters overwhelmingly approved a ballot measure prohibiting new data center development within city limits, with more than 86% supporting the ban, according to CBS Sacramento. The decisive vote reflects mounting public skepticism about hosting facilities that consume substantial electricity and water while generating noise and heat.

Residents in Calistoga have similarly voiced opposition during public meetings over potential data center construction on the Napa County Fairgrounds, CBS Sacramento reported.

Newsom defends local control

Gov. Gavin Newsom said development decisions should remain with local governments rather than being mandated at the state level. "I believe localism is determinative," Newsom stated. "It's a local planning decision, and I think that's appropriate."

However, Newsom also emphasized that major technology companies should contribute financially to the infrastructure their operations require. "You're Microsoft. You can afford to make those contributions. You're Google. You can afford to make those contributions," he said.

The governor has directed the California Public Utilities Commission to develop recommendations on data center regulation that would protect residents from higher electricity costs.

Industry defends strategic placement

Paul Royere, senior vice president of finance and administration at Stockton-based Nautilus Data Technologies, argued that properly sited data centers can benefit communities. "Built in the right areas under the existing environmental and permitting requirements, data centers are a net add to communities," Royere told CBS Sacramento.

He advocated for locating facilities in industrial zones with existing infrastructure rather than residential or rural areas. Most data center operators declined to provide information about their water and energy consumption when contacted by CBS Sacramento.

Why it matters

The local backlash against data centers creates a potential bottleneck for AI development in California, which has positioned itself as the technology's global hub. As AI models grow more sophisticated and power-hungry, companies need exponentially more computing capacity. If communities continue blocking new facilities, technology firms may need to build elsewhere or face constraints on expansion—potentially shifting economic benefits and jobs to other states or countries.

Legislative action pending

Several bills moving through the California Legislature would establish new oversight requirements for data center operators. Proposed measures include mandatory public reporting of monthly water and energy usage, and incorporating data centers into the state's water shortage planning processes.

While data centers have operated in California for decades, the AI boom has accelerated development interest across the state, intensifying debates over their appropriate role in local communities.
