The Hayward City Council voted unanimously Tuesday to approve a moratorium on new data center proposals.
The vote was largely in response to community outcry over the May 2025 approval of the 310,000-square-foot STACK “SVY03A” data center on Eden Landing Road on the city’s west side industrial zone.
The moratorium can last up to two years and is “intended to call a timeout to give city staff time to analyze the cumulative impacts of current and potential future data center development on energy and water supplies, air quality, industrial noise levels, city emergency response capacity and city economic development priorities,” according to a news release from Hayward officials.
During the pause, city officials can mull over permanent changes to land-use and zoning rules related to data centers.
Currently, there are four existing and approved data centers near a PG&E substation in Hayward’s industrial westside:
- A 24 megawatt (MW) facility called SF09 operating on a 10.9-acre site along Corporate Avenue.
- A 35MW facility called SF11 operating on a 4.24-acre site also on Corporate Avenue.
- A 49MW facility called Hayward Exchange @92 operating on 6.57 acres of a larger industrial campus along Clawiter Road near Breakwater Court.
- A 76.6MW facility called Stack Data Center (SVY03A) under construction on an 11.3-acre site on Eden Landing Road.
“Additionally, the city has been approached by a developer planning to submit applications for two new data centers that would operate each within a half mile of Hayward’s existing data centers,” according to city officials.
Several other Bay Area cities have enacted similar data center moratoriums, including Oakland, San Francisco, Gilroy, Richmond and Oakley.
