Update: All Trails Closed West of Highway 36 Due to High Wind Conditions (2024)
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.
Affordable housing remains the top priority identified in the 2025 Community Survey. Boulder County’s Worthy Cause program has funded 252 affordable housing units since its inception, with 152 additional units in the development pipeline.
Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $394,000, making it one of the largest collaborative efforts in the county’s history.
