disclosure → pass → state
California currently ranks third among U.S. states in overall data center density, according to independent trackers like the US Data Center Map, with the state home to 366 of such facilities that are either fully operational, under construction, or moving through the planning process.

asserted
Board → approve → feedback
In Santa Clara, city officials considered a moratorium vote, and are moving forward with new rules to govern data center development, including more stringent water and air pollution regulations.

asserted
Kelly → power → railroads

asserted
developments → acknowledge → friction
To address these fears without stopping construction, his organization promotes an “AI Community Compact” — an agreement offering local guarantees to protect ratepayers from cost spikes, safeguard resources, and promise early transparency.
asserted
organization → address → transparency
“So, communities can decide whether they want data centers there or not, but they shouldn’t just blanket ban them because then you lose all your negotiating power,” Kelly said.
