Chase Center

This guide to Chase Center in San Francisco starts with a plan that never got built: a 2012 proposal to float the Warriors' new arena over the bay on two crumbling piers, and the public revolt that killed it by 2014. It follows the team's pivot to a Mission Bay lot once owned by Salesforce, where engineers digging into the ground made an unsettling discovery about what was buried beneath it, left over from the 1906 earthquake. Stand still for a moment and think about what's under your feet.
