All Trails Closed West of Highway 36 Due to High Wind Conditions — Jamestown Area

Boulder County Parks & Open Space has closed all trails and trailheads west of Highway 36 due to sustained winds exceeding 80 mph and extreme fire danger conditions. The closure includes all mountain parks, open space properties, and county trails in the foothills. Closures will be reassessed when wind conditions subside.

The project includes improvements along Nelson Road between Nederland and the intersection with Baseline Road. Construction is scheduled to begin in July 2026 with completion expected within 6 months.

The application deadline is May 3, 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 18 business days.

Eligibility

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 15% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Volunteers contributed over 3,459 hours to this program last year. The Assessor’s Office coordinates with 17 nonprofit partner organizations throughout Boulder County to deliver services.

Timeline

Water quality monitoring at 9 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Assessor’s Office publishes quarterly water quality reports on the Boulder County website.
