The Willow Spring Service Center is the office and work space for the District’s forestry and horticulture crews. The facility sits on the edge of Willow Spring Open Space, which spans 158 acres and includes a network of trails as well as opportunities for recreation and viewing wildlife. The site is home to the District’s annual Christmas tree recycling and free mulch program.

Load up on mulch, just in time for gardening season! From now through the end of May, community members are invited to pick up mulch from the Willow Spring Service Center.

Stop by any weekday from 8 am-2 pm to load up from two free mulch piles. No appointment necessary, just bring your tarps, buckets and shovels. Please drive slowly through the service center.

The service center is not chipping or accepting any kind of debris. Dumping fines and penalties apply.

What: Free Mulch Pickup
Where: Willow Spring Service Center (7100 S. Holly St., Centennial, CO 80112)
When: Weekdays from 8 am-2 pm (no cars will be permitted to enter after 2 pm)

Projects range from one-time activities for larger groups to recurring opportunities for individuals or small groups. We have a variety of forestry and horticulture related volunteer opportunities.
