Reopenings and restrictions

Gov. Gavin Newsom’s reopening system classifies counties into four tiers based on metrics developed by state officials. Which tier a county falls in determines what can be reopened.

Mariposa County is currently in Tier 4, which allows most businesses to reopen.

Tier 1


Most nonessential indoor business operations are closed

Tier 2


Some nonessential indoor business operations are closed

Tier 3


Some business operations can open with modifications

Tier 4


Most business operations can open with modifications

The state is now using three statistics to judge counties. With some exceptions, metrics must surpass the benchmark for the next tier in order to loosen restrictions. The latest numbers, along with tier reassignments, are released each Tuesday.

The first is called the adjusted case rate. It takes new cases in a recent seven-day period — excluding cases at prisons and jails — and adjusts for population. In some areas, that number is modified to account for the volume of testing. Mariposa County's most recent adjusted case rate was 0.8.

The second metric is the positive test rate, which is the percentage of tests for the virus that come back positive. Mariposa County's most recent positive test rate was 0.7%.

The third metric measures whether positive tests in the most disadvantaged neighborhoods have significantly exceeded a county's overall rate — a disparity that's been widespread during the pandemic. The statistic is known as the Healthy Places Index. The population in Mariposa County is too small to qualify for this measurement.

Based on its current tier in the state framework, here’s what is allowed to open in Mariposa County.
