The first phase, approved by the city in 2024, is not covered by the moratorium. Councilmembers could consider extending the pause before it expires.

The vote followed a contentious council meeting and demonstrations by about two dozen people outside City Hall. Protesters raised concerns about the project’s proximity to homes, a school and a church, as well as potential health effects. Those concerns were voiced by residents; no health impacts were established at the meeting.

Pittsburg resident Marta Rodrigues said she lives close to the proposed development and is worried about possible illness, noting its proximity to a church and school.

Demonstrators interrupted the start of the meeting, which was briefly paused. Police escorted protesters out of the council chambers, and the meeting resumed with public comment. Residents urged officials to reject the project and protect places where children learn and play. Councilmember Jelani Killings acknowledged that residents had expressed substantial concern and fear about what the development could mean for Pittsburg.

The local dispute is unfolding ahead of the November election, with Proposition 45 adding to the debate. Opponents of the measure argue it could weaken environmental and public review for some projects, including data centers. Woody Little of Clean and Healthy California said the measure’s definition of broadband internet projects was too broad.

A legal analysis by the California Chamber of Commerce disputes that interpretation, saying conventional data centers would not qualify because they do not provide mass-market retail internet access directly to customers.

For now, the council’s action creates a limited window for review of later project phases, while leaving the already approved first phase untouched.
