January: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

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.

Eligible participants include Boulder County residents with household incomes at or below 40% of Area Median Income (AMI). For a family of four, this is approximately $115,000 per year. Applications are processed on a first-come, first-served basis.

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 2208 county employees across 44 departments and offices.

Resources

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 40% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Environmental review of the project area near Flagstaff Road found 12 sensitive species and 2 wetland areas requiring mitigation. The Area Agency on Aging worked with Colorado Parks and Wildlife to develop a habitat conservation plan.
