We wrote about the 209 data-center question back when it was still a question. It is not one anymore. On Tuesday, August 18, the Patterson City Council voted unanimously to extend its temporary halt on new data-center projects by ten months and fifteen days, pushing the pause out to July 15, 2027.
Unanimous, August 18, 2026, Patterson City Council.
From a 45-day pause to a stop that now runs through July 15, 2027.
Data centers are already allowed in Patterson's industrial zones under existing code.
Hundreds of residents packed City Hall on August 12 over projects that do not formally exist yet.
What the moratorium actually buys.
A moratorium is not a ban. It is time. Patterson's problem is that its existing zoning already permits data centers in industrial zones, which means a developer could have walked in and been technically compliant before the city had written a single rule about water draw, grid load, noise, or air quality. The 45-day version was a hand on the door. The extension is the city admitting it needs the better part of a year to write the rules properly.
The water piece is not abstract in Patterson. The city is under mandatory groundwater reduction requirements. Longtime resident and business owner Linda Mendoza put the concern plainly to CBS Sacramento: the city already has a water issue, and the question is whether this makes it worse. Her second point was about transparency, and it is the one worth sitting with — residents want to know exactly what a facility of this kind would cost them before it arrives, not after.
Modesto is a different problem.
On August 12, hundreds of Modesto residents filled City Hall to tell council members they did not want data centers in town. The unusual part: there is no application. No site. No project. City officials confirmed that data centers are not currently permitted under Modesto's municipal code at all, and that any proposal would need a code change, environmental review, and approvals from both the planning commission and the council.
So a room full of people turned out to oppose something that would require four separate public steps before it could exist. Read that as apathy about process if you want. We read it as a town that watched what happened elsewhere and decided to show up early. Councilmember Chris Ricci moved his position during the meeting and came out for a moratorium and for writing a ban into city code. Mayor Sue Zwahlen declined to comment on the moratorium request.
Why the 209 keeps landing on these lists.
The pitch to a valley town is always the same three things: property tax base, construction jobs, and a modernization story. The costs are less photogenic. A large facility wants firm power and a lot of it, it wants water for cooling, and the permanent headcount after construction is small relative to the footprint. None of that makes data centers automatically bad. It makes them a trade that a city should price before it signs, and pricing takes rules.
That is the useful thing about what Patterson did. It did not decide the question. It refused to decide it by accident.
What to watch next.
Three things. Whether Patterson's staff comes back with an actual ordinance rather than a second extension. Whether Modesto follows Ricci's position into a formal moratorium or leaves the code silence as its answer. And whether the irrigation districts, which control the water and in this valley are their own centers of gravity, start setting terms of their own.
