Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Pine Brook Hills 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.

Eligible participants include Boulder County residents with household incomes at or below 30% of Area Median Income (AMI). For a family of four, this is approximately $107,000 per year. Applications are processed on a first-come, first-served basis.

Water quality monitoring at 20 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Public Health publishes quarterly water quality reports on the Boulder County website.

Safety data from the Longmont area shows 9 reported incidents in the past 12 months, a 18% change from the previous year. The Sheriff’s Office has increased patrols along Foothills Highway and added community outreach programs in response to resident feedback.

The application deadline is May 10, 2026. Late applications will be accepted on a space-available basis. Incomplete applications will be returned with a list of missing items. Average review time is 5 business days.

How to Participate

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Longmont and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.
