Public Health Issues Air Quality Advisory for Western Foothills Near Sunshine Canyon

Boulder County Public Health has issued an air quality advisory for communities in the western foothills due to elevated particulate matter levels from prescribed burns in the Roosevelt National Forest. Residents with respiratory conditions are advised to limit outdoor activity and keep windows closed until conditions improve.

Funding of $162,000 for this initiative comes from a combination of federal grants, state matching funds, and the Boulder County General Fund. The Board of County Commissioners approved the allocation during the 2026 budget session.

Water quality monitoring at 18 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Community Planning & Permitting publishes quarterly water quality reports on the Boulder County website.

Community Impact

The Coalton Trail open space property encompasses 1,694 acres and features 14 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.
