Future soil cleanup phases
As of November 2022, Phases 1 and 2 of the contaminated soil cleanup have been completed, including capping the trails, capping the former skeet range to create a parking area, and restoring six acres with native vegetation. To complete the cleanup, approximately ten more acres will be restored with native vegetation in phases every three years until complete (estimated to be complete in 2030).
To formalize implementation of this cleanup, in mid to late 2023, King County and Department of Ecology will be amending the 2013 Agreed Order for contaminated soil cleanup to include the schedule for implementation of the cleanup. As part of this amendment process, Department of Ecology will be sending out a Public Notice soliciting public comment. However, since multiple phases of the cleanup have already been voluntarily completed by King County, this agreed order amendment process is primarily a formality to ensure the cleanup meets the requirements in the state’s Model Toxic Controls Act.
Site management plan
The Friends of Maury Island Marine Park (FOMP) have offered to serve in a planning advisory role to assist King County’s efforts to finalize the Site Management Plan for the Maury Island Natural Area. This management plan covers all future use of the natural area, not just the plans for cleanup. A draft was prepared in 2013 but could not be finalized until the details of the cleanup were decided. Now that the details for the cleanup are known, Parks staff will work with FOMP to finalize the management plan.
