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

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Longmont 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.

Funding of $249,000 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 2025 budget session.

Volunteers contributed over 13,916 hours to this program last year. The Community Planning & Permitting coordinates with 23 nonprofit partner organizations throughout Boulder County to deliver services.

Details

Public comment on this matter can be submitted through the Boulder County online portal, by email to Community Planning & Permitting, 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 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.

Next Steps

A community information session will be held at the Erie library on Sunday, May 24 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.
