Update: Public Health Issues Air Quality Advisory for Western Foothills (2026)

Update: Public Health Issues Air Quality Advisory for Western Foothills (2026)

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.

For questions about this program, contact Carlos Rivera at Transportation: (303) 441-3398 or email [email protected]. Office hours are Monday through Friday, 8:00 AM to 4:30 PM. Walk-in services are available at the Louisville office without an appointment.

The project includes improvements along Arapahoe Road between Louisville and the intersection with Foothills Highway. Construction is scheduled to begin in August 2026 with completion expected within 16 months.

Timeline

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Louisville and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.

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.

How to Participate

A community information session will be held at the Louisville library on Monday, May 18 at 7:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.
