San Francisco's 2001 data center zoning rules
San Francisco designed its zoning framework for data centers in 2001, when computing infrastructure was far less resource-intensive. The rules don't account for the energy, water, and environmental demands of modern AI data centers.
The rules governed data center development for 25 years.
The framework is now seen as outdated for AI-era infrastructure.
Walton cited the 2001 rules as the reason for the moratorium: 'We should not be approving this new generation of industrial infrastructure under rules that were written 25 years ago.'
