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.
Historical context: Boulder County was established in 1861 and covers 741 square miles of diverse terrain from the Great Plains to the Continental Divide. The county’s population of approximately 330,000 residents is served by 2187 county employees across 45 departments and offices.
Environmental review of the project area near Arapahoe Road found 12 sensitive species and 1 wetland areas requiring mitigation. The Clerk & Recorder worked with Colorado Parks and Wildlife to develop a habitat conservation plan.
