Patterson Weighs Data Center Freeze Until 2027 Amid Water Crisis
City Council considers extending a development moratorium to study utility impacts in a critically overdrafted basin.
The Patterson City Council is considering a significant extension of a moratorium on data center development to evaluate the environmental and infrastructural costs of the industry. If approved, the freeze would extend the current 45-day pause by an additional 10.5 months, potentially blocking new projects until July 15, 2027.
The proposed extension, which would run from August 30 through mid-2027, requires a four-fifths vote from the council to pass. The initial 45-day moratorium was first imposed on July 16, 2026. According to a city staff report, the move is necessary because data center development poses an "immediate threat to the public health, safety, and welfare of the city" due to its potential to strain energy and water supplies, as well as create noise and air emission issues.
The Regulatory Gap
The urgency of the moratorium stems from a loophole in Patterson's current municipal code, which permits data centers "by right" in industrial zones. This designation allows developers to build these massive facilities with minimal city review or oversight. By implementing the freeze, city leaders aim to conduct a comprehensive study on how such facilities impact air quality, noise levels, and energy infrastructure before updating land-use laws.
Environmental Stakes
The push for stricter oversight is driven largely by the region's precarious water situation. Patterson is located within a groundwater basin currently in critical overdraft and is already participating in a pumping reduction program. Data centers typically require millions of gallons of water for cooling systems, a demand that could prove unsustainable for a city already struggling with depleted aquifers.
This local tension mirrors a broader trend across California and the U.S., where the explosion of artificial intelligence, cloud computing, and e-commerce has triggered a surge in data center construction. The strain is being felt regionally; nearby Modesto has also held discussions regarding its own moratorium, noting that data centers are not currently a permitted land use in its own municipal code.
What's Next
City officials must now determine if the four-fifths majority is attainable to secure the extension. If the council fails to extend the moratorium, developers may be able to move forward under the existing "by right" permissions. The city's primary objective remains the creation of a framework that balances the economic potential of the tech industry with the physical limits of its water and power grids.
