Five Bay Area counties and the city of Berkeley on Friday announced that they are rapidly adopting new, tougher COVID-19 activity restrictions rather than wait for the middle of the month when the region’s ICU bed capacities are anticipated to trigger the state’s new, stricter stay-at-home rules.

Alameda, Contra Costa, Marin, San Francisco and Santa Clara County are admonishing all non-essential gatherings among people in different households and curtailing outdoor activity to levels ordered by health officials near the start of the pandemic in March. Among other things, that means outdoor dining will be shut down and retail businesses will have to shrink capacity further.
