SAN FRANCISCO (KGO) -- Alameda County became the fourth Bay Area county to join the orange tier Tuesday. That means looser capacity restrictions on certain businesses and the ability to reopen for the first time for a few others.
When the orange tier changes take effect Wednesday, here's everything that will change:
Alameda County's case rate of 2.6 COVID-19 cases per 100,000 residents and its test positivity rate of 1.1% earned it a move into the orange tier. It has to stay in the orange tier for three weeks before it could be eligible to move into the yellow tier, the state's most relaxed classification.
