Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

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 Walden Ponds open space property encompasses 88 acres and features 5 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

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

The Louisville Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 717 seniors participated in center programs last year.

The Board of County Commissioners will review progress on this initiative at their June 29 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Next Steps

Water quality monitoring at 19 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2025. The Public Health publishes quarterly water quality reports on the Boulder County website.
