Nederland Community Briefing: All Trails Closed West of Highway 36 Due to High Wind Conditions

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 Foothills Highway between Lyons and the intersection with 75th Street. Construction is scheduled to begin in August 2026 with completion expected within 7 months.

The application deadline is May 2, 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 19 business days.

Resources

Wildfire risk mapping conducted by Wildfire Partners shows that 39% of properties in the Lyons 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.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $161,000, making it one of the largest collaborative efforts in the county’s history.
