Duwamish Waterway Park Activation

Updated: August 17, 2021

Summer 2021

Seattle Parks and Recreation (SPR), Seattle Parks Foundation, and the Friends of Duwamish Waterway Park, are excited to announce the play area at Duwamish Waterway Park, 7900 10th Ave. S in South Park, is open. SPR purchased the1.3-acre site from King County after a community-led process to make the property a permanent neighborhood riverfront park. Working with the Seattle Parks Foundation, the Friends of Duwamish Waterway Park raised over $1 million for park improvements and launched the renovation effort.

The community led and funded park project is carefully designed to maximize open space for recreation and festivals, and to preserve river access for launching hand-carried boats. The park provides a new play area, an accessible perimeter pathway with a series of interpretive artwork boulders, new park furnishings with accessible picnic tables, barbecues, as well as a drinking fountain and food wash area.

The play area is the only section of the park open. The additional park space will open in mid-October after turf is established. The community is being asked to please stay off the grass seeded area to allow time for it to grow. An opening community celebration is scheduled for October 23 when the entire park will be open to the public.

During the purchase of the 1.3 acre property, Seattle Parks and Recreation (SPR) was made aware that the soil beneath the grass next to the river, in the northeastern portion of the property, contained elevated levels of arsenic and lead. In preparation for park renovations, SPR submitted a Remedial Investigation Report to the Washington State Department of Ecology. This report is being revised to incorporate Ecology's comments and results from the current soil remediation work.

At the end of September/early October, prior to park renovations, remediation work was completed in the northeastern portion of the park. The work started with careful excavation around the tree areas, followed by deeper excavations outside of critical tree root zones. Off site soil disposal was delayed slowing the cleanup process. Excavated materials from the park renovation were removed from the site and we will continue to sample excavated trench lines to check for any other soil contamination. Cleanup on non-Seattle Parks and Recreation property is not included in this project.

Project Description

Construction began in late September 2020 (Construction Begins Press Release - English; Spanish; Vietnamese).

Public planning through the Duwamish River Cleanup Coalition's Healthy Communities program (2013) and Seattle Parks Foundation's South Park Green Spaces Vision Plan (2014) have identified Duwamish Waterway Park as a key open space in the community in need of improvement. There is a strong interest from the community to create more amenities to draw people to the park.

The community vision provides significant improvements to the park to make it a healthy and welcoming space for families, young people, and seniors. The Friends of Duwamish Waterway Park have led the years-long effort to translate the community's vision for the park into a final design. The community driven design provides more welcoming park entries and includes:

  • an improved perimeter pathway with a series of interpretive artwork boulders that enhance the river view with messages relating to the community and the area history; 
  • an all-ages accessible playground including a climbing structure and zip line as well as boulders, logs, and benches; and
  • new park furnishings with accessible picnic tables, barbecues, drinking fountain and foot wash, additional benches, and bike racks.
