Dockton marina renovation, here we come!

*This page was last updated on September 15, 2021.*

Moorage renovation began Sept 10

This phase includes the bulk of the renovation work:

  • Removing and replacing creosote-treated piles
  • Installing a new pump-out station
  • Repairing cross-bracing
  • Replacing the access dock, center moorage, and walkway
  • Installing a new fire suppression system
  • Installing new interior floats

What to expect during construction

  • Entire marina will be CLOSED for duration of construction
  • Restrooms and picnic shelter will be CLOSED for approx 3 weeks (Starting Sept 10)
  • Parking lot will be open, but limited, as the area will be used for staging
  • Play area and boat ramp will remain open

Notice: Construction crews will conduct pile driving on Mon, Sept 20 and Tues, Sept 21, which will cause noise and vibration in the area around the harbor.

Boats are NOT permitted to tie up at the dock during construction. With the exception of boat ramp, there will be no way to access land from the water during construction.

Project overview

We’ve been completing the moorage renovation in stages. To date, we’ve removed the interior and breakwater finger piers. After this round of construction, the only remaining renovation work includes replacing the breakwater.

The new moorage facility will feature fish habitat-friendly features, such as open grated decking, which allows more light to pass through, and new or wrapped steel piles, which won’t leach pollutants like the old creosote-treated ones. We’ll also add non-skid coating to make the fixed dock much easier to navigate with your sea legs!

Once the current phase of work is complete, we will re-open the moorage facility for public use with space for 30 boats. The breakwater will remain closed until it is replaced, which we anticipate doing in 2023.

We anticipate being able to re-open the facility in early 2022.

While facilities at Dockton Park are closed, be sure to visit other beautiful parks on Vashon and Maury Islands:

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!

  1. Thank you for renovating the dock & facilities. It definitely was needed since it’s the only public dock on Vashon. Speaking of renovating, are there plans to extend the boat launch further out or dig it deeper to allow boats to launch in +2 tide or less? Right now Vashon residence have to rely on the tides to launch their boats.


  2. This is great and important news! Not only is this a great recreational boating facility, but this is an important emergency lifeline for Vashon Island in case of a major disaster like an earthquake or volcanic eruption when the ferries might be forced to shut down. Backup marine transportation plans will be able to rely on this newly refurbished site for landing craft as well as passenger carrying vessels. I’m excited to see it officially open for boaters soon!
