California Data Center Development
Coverage from Data Center Knowledge, Procopio, and others
California communities and local governments weigh proposals for large data centers through decisions about zoning, siting, environmental review, and public approval.
Debates often involve expected water and electricity use, effects on utility infrastructure and rates, noise, and other local environmental or land-use concerns. In Modesto, a potential facility at the former FMC plant site drew public opposition and discussion of restrictions, while Patterson’s moratorium was cited as a regional precedent. Together, these issues show how local policy choices shape where large data centers may be built and how their potential effects are evaluated.

If you read one thing
It gives a broad overview of California siting restrictions, rising grid demand, and the transparency concerns driving local responses.
Latest development
San Francisco’s new approval pause is a high-signal recent example of jurisdictions turning impact review and community input into siting rules.
Best explainer
It explains how a court ruling made comprehensive environmental review a gate for a major project and connects that review to its water and power needs.
The evidence
It adds evidence on local value and accountability, including job and housing effects, community commitments, and possible cost shifts.
The evidence
Eureka’s proposed small-facility zoning shows how limited grid capacity can shape local siting rules.
Key Issues
Local governments are tightening siting controls
California jurisdictions are using or considering moratoria, restrictive zoning, public hearings, and bans to assess impacts and establish local rules. The resulting constraints vary by place, from temporary approval pauses to permanent prohibitions, and some proposals remain pending.
Stable
Resource and grid capacity constrain proposals
Electricity and water availability remain material siting constraints: local infrastructure may have limited headroom, while large facilities can require substantial power and water. Uncertainty about resource demand and potential effects on other utility customers also fuels local scrutiny.
Stable
Comprehensive environmental review is a project gate
Court rulings on Imperial County’s proposed hyperscale facility require review of the integrated project and supporting infrastructure before approvals can proceed. This creates a substantial permitting hurdle, but the rulings do not permanently prohibit the project.
Stable
Community accountability and local value remain contested
Residents and officials dispute whether local benefits justify resource, infrastructure, and neighborhood impacts, and whether the public can access reliable information or secure enforceable commitments. Transparency, utility costs, community benefits, and limited permanent employment are recurring points of scrutiny.
Key Numbers
45 days
initial moratorium duration
“The interim urgency ordinance takes effect immediately for 45 days. Under California law, the council can extend the moratorium in two phases for a maximum total period of two years. During the pause, the city cannot accept, process or approve applications and entitlements for new data center facilities.”
about four times
comparison with San Jose’s average peak demand
“The utility has approximately four gigawatts of data center demand under construction or in final approval stages, about four times San Jose’s average peak demand.”
10 megawatts
remaining substation capacity
“PG&E has told the city that one Eureka substation is already at capacity, while another has approximately 10 megawatts of remaining capacity and a planned upgrade.”
50 to 100 megawatts
power demand sought by newer data centers
“She contrasted the approximately one-megawatt EdgeConnex facility in nearby Arcata with newer facilities seeking 50 to 100 megawatts and the largest artificial-intelligence campuses, which can require hundreds or more than 1,000 megawatts.”
one megawatt
power demand of the EdgeConnex facility
“She contrasted the approximately one-megawatt EdgeConnex facility in nearby Arcata with newer facilities seeking 50 to 100 megawatts and the largest artificial-intelligence campuses, which can require hundreds or more than 1,000 megawatts.”

The Story So Far
Escalation
Gilroy adopts a moratorium as Bay Area cities advance pauses
Gilroy has imposed a temporary halt on new data-center development while it drafts siting standards, leaving its approved Amazon facility untouched but blocking a second proposed project. San Francisco supervisors have also approved a temporary pause, pending the mayor’s action. These steps move beyond the earlier focus on jurisdictions considering restrictions, though the pauses remain temporary and do not stop all development.
Previously
Cities and counties across California’s Central Valley are reviewing or restricting prospective data center projects, with some officials considering moratoriums, zoning changes, or bans. Residents and local leaders are weighing electricity and water needs, utility costs, noise, jobs, and public disclosure before deciding whether and how projects could proceed. The debate is primarily about proposed facilities rather than approved construction, although a separate Sacramento expansion is moving ahead.
History
10/09/2026
The story has broadened beyond the Central Valley to Bay Area cities, where officials are considering or advancing additional approval pauses and local data-center rules. The new examples highlight gaps in land-use definitions and tracking, alongside debates over municipal revenue and community impacts.
10/05/2026
The update adds concrete local policy steps: Stockton removed data centers from its economic development plan, while Riverbank and Fresno considered specific pause or prohibition periods. The broader review-and-restriction story remains unchanged.
