Blueprint Update: Marin County remains in Tier 3

Today, California Department of Public Health (CDPH) provided its weekly update on the Blueprint for a Safer Economy, a statewide plan for reducing COVID-19 and keeping Californians healthy and safe.

CDPH confirmed Marin County’s placement in Tier 3 (orange status) for a third straight week. CDPH’s November 10 assessment for Marin County includes:

  • Testing Positivity: 1.1% (increase of .1% since last assessment)
  • Adjusted Case Rate: 2.5 (decrease of .1%)
  • Health Equity Quartile Test Positivity Rate: 1.3% (decrease of 0.1%)

The following table outlines the requirements for case rates, test positivity rates, and quartile test positivity rates for each tier status. Currently, two of Marin’s three measurements qualifies for Tier 4 (yellow status):

  Tier 1
Tier 2
Tier 3
Tier 4
Marin County
Adjusted Case Rate per 100,000 > 7 4 to 7 1 to 3.9 < 1 2.5
Overall Test Positivity Rate > 8% 5% to 8% 2% to 4.9% < 2% 1.1%
EquityQuartile Test Positivity Rate > 8.0% ≤ 8.0% ≤ 5.2% ≤ 2.1% 1.3%

In general, for a County to advance to a less restrictive tier, it must (1) have been in the current tier for a minimum of three weeks; and (2) meet criteria for the next less restrictive tier for all three measures for the prior two consecutive weeks in order to progress to the next tier.
