Sedum bed at Closed Loop Park

Closed Loop Park

An excellent example of how to reuse a former landfill site.

The Closed Loop Park Demonstration Garden is developed and maintained by Thurston County Solid Waste Division and WSU Thurston County Extension Master Gardeners and Thurston County Master Recycler Composters.

This ornamental garden is an excellent example of how we can reuse a former landfill site. It sits on only 18 inches of soil above an impermeable protective liner to nourish a wide variety of plants, shrubs, and trees.  Come out and stroll through the two-acre garden and view over 100 varieties of sedum and peonies.

In addition, Closed Loop Park also houses test beds for several “Great Plant Picks,” a large composting demonstration area, native gardens, a quiet picnic area among the beds, and a gazebo for relaxing. Please note that Closed Loop Park is not a dog friendly garden. The garden has been here for over 30 years and some of the plants are part of a long-term trial so they can’t be removed.  We encourage you to visit the Thurston County Dog Park which is adjacent to Closed Loop Park.
