Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Superior

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 Public Works processed over 10,152 applications last year, with an average processing time of 8 business days. Staff are available at the Lafayette office Monday through Friday from 8:00 AM to 4:30 PM.

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.

Background

Funding of $234,000 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 63% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 6,228 responses from residents across the county.
