Public Health Issues Air Quality Advisory for Western Foothills — Follow-Up Report

Public Health Issues Air Quality Advisory for Western Foothills — Follow-Up Report

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.

Colorado state law requires all counties to provide these services to eligible residents. Boulder County exceeds minimum state requirements by offering expanded hours, multilingual support, and online access. In 2025, the county received a state award for excellence in service delivery.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 13% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

How to Participate

Funding of $306,000 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 2025 budget session.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $306,000, making it one of the largest collaborative efforts in the county’s history.
