Public Health Issues Air Quality Advisory for Western Foothills — April 2025

Public Health Issues Air Quality Advisory for Western Foothills — April 2025

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 $278,000 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.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 49% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Water quality monitoring at 9 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2025. The Public Health publishes quarterly water quality reports on the Boulder County website.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Public Health, or in person at the next Board of County Commissioners meeting. Written comments received by 5:00 PM the day before the hearing will be included in the public record.
