Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

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.

According to Brian Nakamura, director of Public Health, this program served 92% more residents in 2025 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Louisville and the surrounding area,” Brian Nakamura said.

Funding of $97,000 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.

Data from the 2025 Boulder County Community Survey shows that 92% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 6,365 responses from residents across the county.

Background

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 92% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
