Starting Friday in Marin County & Sonoma County, people must wear masks at all times when using essential services such as the grocery store or riding the bus. Fremont is also requiring masks. The city has issued an executive order making it mandatory for workers and customers at most essential businesses to cover their faces. This means wearing masks at restaurants, gas stations, grocery and hardware stores. For those who don’t comply, the fine is up to $100.

Countering this move, some counties are relaxing restrictions. For example, Santa Cruz County has already taken a small step in reopening its beaches and parks. Bay Area public health officials will watch the reaction to the beach and park reopening carefully before considering whether to open similar waterfront sites, such as Ocean Beach in San Francisco, Pillar Point Harbor in San Mateo County or Jack London Square in Oakland.
