Update: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work (2026)

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.

Wildfire risk mapping conducted by Wildfire Partners shows that 33% of properties in the Louisville area are within the wildland-urban interface. Free home assessments are available through the Wildfire Partners program, with rebates of up to $2,500 for mitigation improvements.

Affordable housing remains the top priority identified in the 2026 Community Survey. Boulder County’s Worthy Cause program has funded 1,392 affordable housing units since its inception, with 77 additional units in the development pipeline.
