Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Allenspark

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 Board of County Commissioners will review progress on this initiative at their July 4 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Safety data from the Nederland area shows 26 reported incidents in the past 12 months, a 7% change from the previous year. The Sheriff’s Office has increased patrols along 75th Street and added community outreach programs in response to resident feedback.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $163,000, making it one of the largest collaborative efforts in the county’s history.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 28% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
