Site Restoration Work

Restoration work at Maury Island Natural Area is almost complete! Contractor crews removed invasive vegetation and replanted three acres of the park, in the area south of SW 260th Street, near the cell phone tower (worksite map). In order to protect the plants, we have temporarily fenced the area and laid weed fabric, which will be in place until the plants are established, typically 3 to 5 years. In early 2017, contractor crews will complete the work by restoring the trail to its original pre-construction condition. 


Located on the southeast shore of Maury Island on lands formerly operated as a sand and gravel mine, the Maury Island Natural Area is now a 275-acre park. The park contains pure Madrone forests and habitat that supports endangered species, such as Chinook salmon, orca and bull trout. The site’s nearly one mile of shoreline is the longest undeveloped stretch of Puget Sound shoreline in King County. When combined with the nearby 320-acre Maury Island Marine Park, the two parks represent the largest public holding of protected marine shoreline in all of Puget Sound.

Citizen activists and environmental groups fought plans for mine expansion and advocated for public acquisition of the site, which was purchased in December 2010. Acquisition funding came from the King County Conservation Futures Tax, Washington State Department of Ecology ASARCO Settlement fund and an amendment to CalPortland’s existing royalty agreement for another mining site. In addition, community groups including Forterra, People For Puget Sound, Preserve Our Islands, Vashon-Maury Island Land Trust, and Washington Environmental Council began a fundraising campaign to help ensure the site would be protected and cared for in perpetuity.

Due to previous mining activity and the site's location within the historic Tacoma Smelter plume, plans for land reclamation and soil remediation have been an integral part of site management planning. King County Parks has been working with a planning advisory group, which helped identify appropriate site uses and amenities, such as trail improvements, water access, restroom facilities, picnic areas and parking. We will finalize those recommendations as part of the planning process and in coordination with the Washington Department of Ecology.

For more information about the acquisition, read the press release from 2010.

Access: The park can be reached from Seattle by the Fauntleroy-Vashon ferry and from Tacoma by the Point Defiance-Tahlequah ferry. Once on Maury Island, head south on Dockton Road SW, east on SW 260th St. There is no formal access or parking on site, but non-motorized access is allowed via the gated maintenance road.
