Marina and Playground Improvements

Dockton Marina is open with moorage for up to 30 boats.

A multi-year project consisting of two phases is underway to improve the Dockton Marina. Completed in May 2022, Phase 1 replaced various piles and finger piers internally on the dock. Other improvements include new swim dock, fire suppression system, sewage pump out station, hardware replacements, nonskid coating, fixed pier cross bracing replacement (under bathroom). The new dock is constructed with plastic grating that lets light through and creates better habitat for sea life. 

Phase 2 is in final design and will include removal and replacement of deep-water creosote piles, replacement of breakwater section of floating dock, and replacement of the boat ramp dock. Construction is estimated for 2024. 

Construction of a new playground begins in summer 2023 and will be finished in fall 2023. The current play area will remain open until that time. The new playground will be a larger, more accessible play area with elements for all ages and abilities to enjoy with an emphasis on climbers, slides, and spinners geared toward 2-to-8-year-olds. In addition, the renovation provides an opportunity to improve ADA access, drainage, and the aesthetics of the park, as well as add new amenities like benches.

Park History

From 1892-1910, the Dockton area was home to the west coast's largest shipbuilding dry dock. To commemorate the significance, an 18' bell tower with the actual historic bell that used to signal shift changes at the dock was installed at Dockton Park in 2007. A walking trail with interpretive signs details the area's history starts at Dockton Park and continues up into the neighborhood.
