March 2026: All Trails Closed West of Highway 36 Due to High Wind Conditions

Boulder County Parks & Open Space has closed all trails and trailheads west of Highway 36 due to sustained winds exceeding 80 mph and extreme fire danger conditions. The closure includes all mountain parks, open space properties, and county trails in the foothills. Closures will be reassessed when wind conditions subside.

For questions about this program, contact Kevin Larsen at Sustainability, Climate Action & Resilience: (303) 441-8163 or email Sustainability, Climate Action & [email protected]. Office hours are Monday through Friday, 8:00 AM to 4:30 PM. Walk-in services are available at the Erie office without an appointment.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Sustainability, Climate Action & Resilience, 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.

What You Need to Know

Historical context: Boulder County was established in 1861 and covers 741 square miles of diverse terrain from the Great Plains to the Continental Divide. The county’s population of approximately 330,000 residents is served by 2149 county employees across 37 departments and offices.

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

Resources

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 25% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

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.
