County of Sonoma’s Roadmap to Reopening

En español »

For a description of the Board’s recently adopted “Project SOS: Safely Open Sonoma” strategies to reduce COVID-19 transmission please read the summary.

Under the State’s Blueprint for a Safer Economy, every county in California is assigned to a tier based on its rate of new cases, overall testing positivity, and the testing positivity of its residents with access to the fewest socioeconomic resources. At a minimum, counties must remain in a tier for at least 3 weeks before moving forward. Data is reviewed by the State weekly and tiers are updated on Tuesdays. To move forward, a county must meet the next tier’s criteria for two consecutive weeks. If a county’s metrics worsen for two consecutive weeks, it will be assigned a more restrictive tier.

State Indicators, Tiers are listed from Higher Risk to Lower Risk of Community Disease Transmission
Indicator Widespread
Tier 1
Substantial
Tier 2
Moderate
Tier 3
Minimal
Tier 4
New cases per 100,000 population per day
(7 day average; 7 day lag)
> 7 4 – 7 1 – 3.9 < 1
Positive tests percentage
(7 day average; 7 day lag)
> 8% 5% – 8% 2% – 4.9% < 2%
