Thanks, it's really confusing because there are multiple conflicting sources with different guidelines and the governor's statements have indicated Phase 2 is still case-by-case and phases 3 and 4 are "sometime soonish". In addition to the metrics that SF Chronicle page is tracking for Bay Area counties, there's also [1], [2], and [3] in addition to the original governor's slides a few weeks ago. I can't find any concrete goals from official sources for completely reopening the state (phase 4).

It even has a checklist with the targets that must be met before a county can lift quarantine.
