Adams, Arapahoe, Boulder and Jefferson counties are extending their stay-at-home orders through May 8, following Denver’s lead as the statewide mandate ends this weekend.

“Extending the order through May 8 is necessary for Jefferson County because, unlike some areas of the state that have less population density, we have not yet seen a decline in daily COVID-19 cases, nor do we have sufficient testing capacity or data about community compliance,” Jefferson County’s public health department said Friday in a news release. “Each of these benchmarks are key factors in the decision to phase toward reopening.”

Under the extended orders, Jefferson and Boulder counties will allow non-critical businesses to begin to offer curbside delivery of products. Traveling to pick up these goods will be deemed essential travel, news releases from the counties stated.

The Tri-County Health Department’s board of health decided Friday that Adams and Arapahoe counties would also extend stay-at-home orders to May 8 while Douglas County would begin to relax restrictions Monday with much of the rest of the state, spokeswoman Becky O’Guin said.

According to the Tri-County Health, Douglas County has seen COVID-19 case numbers level off enough in recent weeks that it will not join Arapahoe and Adams counties in extending stay-at-home restrictions. Republican lawmakers from Douglas County last month urged county commissioners to cut ties with Tri-County Health after the agency announced the initial stay-at-home order covering Douglas, Arapahoe and Adams counties.

“No two communities in Colorado are the same, and each community has different needs as we look to the next stages of response to the COVID-19 pandemic,” Dr. Mark B. Johnson, executive director of Jefferson County Public Health, said in a statement. “We have to consider what impact opening too soon could have on those in our community and region, and take a phased, science-based approach to reopening.”

Boulder County has not met the conditions that need to be in place to make sure spread of the virus does not spike again after restrictions are eased, officials said in a news release. Those criteria, laid out by the state, include available testing, controlled transmission and enough hospital capacity, among other indicators.

“We’re in a no-win situation,” Jeff Zayach, Boulder County Public Health executive director, said in a statement. “I know the livelihoods of many people have been significantly impacted by COVID-19. We hope that including the option for curbside delivery for non-critical businesses will help our communities start getting back on their feet.”

Denver officials announced Thursday evening that they planned to extend the city’s stay-at-home order, which was set to expire April 30, to May 8, and that they expected other nearby municipalities to follow suit.

Colorado’s statewide stay-at-home order expires at the end of the day Sunday, and Gov. Jared Polis has announced plans for a gradual reopening of some businesses in the coming weeks under what he called a “safer at home” plan.
