Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Lyons 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.

Wildfire risk mapping conducted by Wildfire Partners shows that 26% of properties in the Longmont 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.

Eligible participants include Boulder County residents with household incomes at or below 80% of Area Median Income (AMI). For a family of four, this is approximately $64,000 per year. Applications are processed on a first-come, first-served basis.
