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.
| 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% |
