Under construction: Dockton Park – marina renovation and bulkhead removal

King County is undertaking two big projects at Dockton Park during the upcoming opening in the fish window. Due to overlapping project timelines, some of the park’s amenities will be intermittently inaccessible, and at times, completely closed to public access. See timetable below.

For the first project, work crews will begin staging equipment on site at the end of July for the removal of a bulkhead; construction gets underway in early August. This project is anticipated to be completed by the end of September.

The second project will begin the renovations of the marina, which has largely been closed since March 2019. This project is anticipated to be completed by April, and we expect to re-open more of the marina for moorage at that time.

About the Bulkhead Removal Project

King County will remove this bulkhead and naturalize the shoreline

During the daytime low tides occurring within the summer fish window (August 1 – September 30), the King County Water and Land Resources Division will use heavy equipment to break up and haul away the 225-foot-long concrete bulkhead north of the marina. Construction hours go from 7 a.m. to 7 p.m., Mon – Fri, so expect a higher noise level during this time.

Removing this bulkhead will improve shoreline habitat for juvenile Chinook salmon and their prey, including the endangered Southern Resident Orca who rely on Chinook salmon as their primary food source.

This project was funded with a competitive state grant from the Estuary and Salmon Restoration Program. This project is expected to be completed before September 30, 2020.

About the Marina Renovation Project

The first step toward renovating the marina begins with the removal and replacement of about 10 – 12 of the old wooden creosote piles inside the breakwater area with new steel piles. This work is expected to be completed within a week of starting, which will be sometime in September.

The second element of Phase One renovations includes replacing the pump-out station and the interior finger dock floats, which will likely happen sometime during the winter. We anticipate opening up the interior marina area to the public in late spring 2021.

As funding becomes available, future work is planned to:

  • Encapsulate or replace the remaining creosote piles
  • Replace the floats on the outer breakwater section
  • Carry out other safety and maintenance items

Please subscribe to the Dockton Park email newsletter for progress updates.

Current construction is funded in part by a Boating Facilities Program grant from the state Recreation and Conservation Office and by the 2020-2025 King County Parks, Recreation, Trails, and Open Space Levy. Thank you for your support!

We are eager to complete these projects and re-open Dockton Park (and additional parts of the marina) as soon as we can. While facilities at Dockton Park are closed, be sure to visit other beautiful parks on Vashon and Maury Islands:

One thought on “Under construction: Dockton Park – marina renovation and bulkhead removal

  1. I collect mussels for the Health Dept Harmful Algae Bloom lab. There has been 2 positive results so I will be needing to access my cage which is out on the breakwater. I will make an effort to pay attention to dates of actual construction.
