The city planning commission approved a conditional use permit 6-1 for the large Grande Valley data center. Nine of ten speakers were against it.
🤝 Agreement with the company
Landowners said the city's new data center permit rule cut their land value and asked for about $140 million under Prop 207. Instead of paying, the city council approved a binding waiver with limits on water, power, noise and site cleanup, plus a $5 million gift for city parks. Any data center still needs site plan review.
