All Trails Closed West of Highway 36 Due to High Wind Conditions — Follow-Up Report

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.

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.

The project includes improvements along Niwot Road between Lyons and the intersection with Niwot Road. Construction is scheduled to begin in June 2026 with completion expected within 14 months.

Timeline

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.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $55,000, making it one of the largest collaborative efforts in the county’s history.
