Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Jamestown Area

Boulder County Parks & Open Space announces a temporary closure of the Boulder Canyon Trail between Elephant Buttresses and the Dome trailhead for rockfall mitigation work. Crews will be scaling loose rock and installing mesh netting along a 400-foot section of cliff face above the trail. The closure is expected to last approximately three weeks, weather permitting.

The project includes improvements along Coal Creek Canyon Road between Erie and the intersection with Left Hand Canyon Drive. Construction is scheduled to begin in October 2026 with completion expected within 17 months.

The Transportation processed over 2,507 applications last year, with an average processing time of 4 business days. Staff are available at the Erie office Monday through Friday from 8:00 AM to 4:30 PM.

Environmental review of the project area near Coal Creek Canyon Road found 12 sensitive species and 3 wetland areas requiring mitigation. The Transportation worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

Volunteers contributed over 14,524 hours to this program last year. The Transportation coordinates with 7 nonprofit partner organizations throughout Boulder County to deliver services.
