California City Becomes First in US to Permanently Ban Data Centers via Ballot Measure

For communities facing the rapid expansion of artificial intelligence infrastructure, the playbook for local resistance has fundamentally changed. Residents no longer have to rely solely on zoning boards, planning commissions, or temporary city council pauses to block massive computing facilities. By taking the issue directly to the ballot box, voters can lock in permanent land-use restrictions that future elected officials cannot easily undo, prioritizing local environmental control over the demands of the global tech industry.[1][2]

That is exactly what happened in Monterey Park, California, where residents overwhelmingly passed Measure NDC on June 2, 2026. With more than 86 percent of the vote, the Los Angeles-area municipality became the first city in the United States to permanently ban data center development through a voter initiative. The measure amends the city's General Plan to prohibit the facilities citywide, effectively closing the border to the digital warehouses that power the modern internet and generative AI models.[2][3]

The landslide vote was triggered by a specific proposal from Australian investment firm HMC StratCap, which sought to build a 247,000-square-foot data center on Saturn Avenue, near a residential neighborhood. The sheer scale of the project alarmed the community of 60,000 people. According to city estimates, the proposed facility would have consumed three times the electricity used by the entire city, placing an unprecedented strain on the local power grid.[3]

Residents mobilized rapidly, citing a cascade of environmental and quality-of-life concerns. Data centers require massive cooling systems that run continuously, generating persistent, low-frequency noise pollution that has plagued other host communities. Furthermore, the immense water consumption required for those cooling systems, combined with the potential for localized spikes in electricity rates, convinced voters that the environmental footprint of the facility was incompatible with a dense, urban residential area.[1][4][5]

While the Monterey Park City Council had already passed an indefinite moratorium on data centers in April and the developer had subsequently withdrawn its application, local organizers pushed for a more durable solution. A standard city council ordinance can be reversed by a future council if political winds shift or industry lobbying intensifies. A ballot measure, however, requires another citywide vote to overturn, creating a formidable legal and political barrier that makes the ban nearly permanent.[2]

The grassroots campaign relied on aggressive community organizing, with residents gathering over 5,300 signatures to force the issue onto the ballot. Organizers argued that working-class and minority communities are often targeted for heavy infrastructure projects, framing the data center fight as an issue of environmental justice. The resulting 86 percent approval margin delivered a definitive mandate that bypassed traditional municipal negotiations.[1][2]

The tech and real estate industries view the Monterey Park vote as a dangerous precedent that threatens the infrastructure required for the AI boom. The Data Center Coalition, an industry trade group, argues that such bans signal a region is fundamentally closed for business. They contend that prohibiting data centers deprives local governments of millions in long-term tax revenue and high-wage technical jobs, pushing critical digital infrastructure to neighboring municipalities or other states.[2][4]

The economic trade-offs of the ban are substantial. City officials had estimated that the HMC StratCap data center could have generated between $3 million and $5 million annually for local services in Monterey Park. By passing Measure NDC, voters explicitly decided that the preservation of air quality, water resources, and grid stability outweighed the financial benefits of commercial tech development.[1][3]

Despite industry warnings about lost revenue, the backlash against data centers is spreading nationally. A recent Gallup poll found that 70 percent of Americans oppose data centers in their communities. Support for the facilities has plummeted even in traditional tech hubs like Virginia, where a recent poll showed only 35 percent of voters remain comfortable living near such projects, down from 69 percent just three years ago.[1][4]

This shifting public sentiment is beginning to influence higher levels of government. While Monterey Park is the first to enact a permanent ban via voters, other jurisdictions, including Imperial County, California, and towns in Wisconsin, have implemented temporary pauses. At the federal level, lawmakers have introduced legislation proposing a nationwide moratorium on AI data center construction until stronger environmental and consumer safeguards are established.[4][5]

The long-term legal viability of the ballot-measure strategy remains untested. While HMC StratCap dropped its threat of a lawsuit against Monterey Park, future ballot measures in other cities could face aggressive legal challenges. Well-funded tech conglomerates may argue that local bans violate state or federal commerce laws, or they may lobby state legislatures to pass preemption laws that strip municipalities of the power to ban digital infrastructure.[2]

For now, however, Monterey Park has provided a concrete, tested blueprint for grassroots coalitions. By successfully weaponizing the ballot initiative process, residents have demonstrated that local communities can successfully reject the physical footprint of the AI revolution, forcing the tech industry to rethink where and how it builds its most critical infrastructure.[1]
