Update: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work (2026)

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.

Environmental review of the project area near Sunshine Canyon Drive found 10 sensitive species and 4 wetland areas requiring mitigation. The Assessor’s Office worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

Volunteers contributed over 9,174 hours to this program last year. The Assessor’s Office coordinates with 25 nonprofit partner organizations throughout Boulder County to deliver services.

Next Steps

A community information session will be held at the Boulder library on Tuesday, June 2 at 5:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

Funding of $192,000 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 2024 budget session.

According to James Rodriguez, director of Assessor’s Office, this program served 45% more residents in 2024 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Boulder and the surrounding area,” James Rodriguez said.
