What happened
The Los Angeles County Board of Supervisors will consider a motion on Tuesday to draft a zoning amendment banning large-scale data centers in unincorporated Los Angeles County. The proposal, introduced by Supervisor Hilda Solis, targets facilities used to power artificial intelligence due to concerns over energy and water consumption and public health impacts. The motion directs the Department of Regional Planning to define and prohibit hyperscale AI data centers while allowing smaller 'beneficial use' facilities. It also calls for a review of noise regulations and identifies funding for the necessary environmental impact analysis.
The Los Angeles County Board of Supervisors is scheduled to consider a proposal on Tuesday to develop a zoning amendment that would prohibit large-scale data centers in unincorporated parts of the county. The motion, introduced by Supervisor Hilda Solis, cites concerns about the high energy and water demands of these facilities and their potential public health effects, particularly those associated with powering artificial intelligence systems.
The motion directs the Department of Regional Planning to draft an amendment to the county’s zoning code. This amendment would establish definitions for different types of data centers based on acreage, square footage, energy use, and water consumption. It specifically aims to distinguish hyperscale and AI data centers from 'beneficial use' facilities, such as enterprise or accessory data centers used for daily computational needs.
The proposed amendment would prohibit all data centers meeting the definition of 'large-scale' in every zone of unincorporated Los Angeles County. The motion argues that it is imperative to act expediently to prevent environmental and health effects from impacting residents. It notes that the growth of AI has fueled the development of hyperscale centers that consume more resources than traditional data storage facilities.
The proposal follows a county study initiated in April, which recommended amending Title 22 of the zoning code to define and prohibit hyperscale facilities. The motion also references opposition to proposed data centers in the San Gabriel Valley, where the board received 101 pages of public comments primarily calling for a moratorium. It cites actions by nearby cities like Monterey Park and Montebello to restrict data center development.
In addition to the zoning ban, the motion directs the Department of Public Health to determine if noise regulations should be amended to address low-frequency noise from large-scale data centers. It also calls for the county’s chief executive officer to identify funding for the zoning amendment and its required California Environmental Quality Act analysis. The motion includes provisions for a potential moratorium if a specific facility poses an immediate threat to public health or safety.

Why it matters
This move represents a significant local regulatory response to the environmental footprint of AI infrastructure. By distinguishing between standard data centers and hyperscale AI facilities, the county aims to address specific resource strains associated with advanced computing. If adopted, this zoning amendment could set a precedent for other jurisdictions facing similar pressures from the rapid expansion of AI data centers, potentially influencing how local governments manage the intersection of technological growth and environmental sustainability.
This policy action highlights the growing tension between the rapid expansion of AI infrastructure and local environmental and public health concerns. By targeting hyperscale AI data centers specifically, the county is acknowledging that the resource intensity of modern AI training and differs significantly from traditional data storage.
The move could have broader implications for the AI industry's expansion in California, a major hub for technology companies. If the zoning amendment is adopted, it may force AI companies to seek alternative locations or invest in more efficient infrastructure, potentially influencing the geographic distribution of data centers.
The proposal also reflects a shift in local governance, where elected officials are taking direct action to regulate emerging technologies based on their tangible environmental impacts. This could encourage other jurisdictions to adopt similar measures, creating a patchwork of local regulations that AI companies must navigate.

What to watch next
Monitor the outcome of the Tuesday Board of Supervisors meeting to see if the motion passes. Watch for the specific definitions of 'large-scale' and 'hyperscale' data centers in the drafted zoning code. Observe whether the county proceeds with the California Environmental Quality Act analysis and if the proposed noise regulation amendments are implemented. Additionally, track reactions from the AI industry and other local governments considering similar restrictions.
The immediate outcome of the Tuesday Board of Supervisors meeting is critical. If the motion passes, the Department of Regional Planning will begin drafting the specific zoning language, which will likely be subject to further public comment and legal review.
The definitions of 'large-scale' and 'hyperscale' data centers will be key to understanding the scope of the ban. These definitions will determine which existing and proposed facilities are affected and whether the ban is narrowly targeted or broadly applicable.
The California Environmental Quality Act analysis will be a significant hurdle. This process can take months or years and may reveal specific environmental impacts that could further justify or complicate the proposed ban.
Reactions from the AI industry and local business communities will be important to monitor. Companies may lobby against the ban or propose alternative solutions, such as voluntary environmental standards or relocation plans.
