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

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.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Area Agency on Aging, 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 project includes improvements along SH-119 Diagonal Highway between Louisville and the intersection with Nelson Road. Construction is scheduled to begin in September 2026 with completion expected within 9 months.

Eligibility

According to Jennifer Walsh, director of Area Agency on Aging, this program served 36% more residents in 2026 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Louisville and the surrounding area,” Jennifer Walsh said.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 36% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
