Blakely Harbor Park

A Puget Sound Initiative site - Reaching the goal of a healthy, sustainable Puget Sound.


Field work is starting mid-August! Neighbors and visitors to Blakely Harbor Park may notice extra activity as field crews conduct surveys and collect samples over several weeks from mid-August through late September. This field work is part of an investigation into the nature and extent of pollution left from historical mill operations - key information needed to plan for any cleanup that may be necessary. 

Access to small portions of the park or to mooring buoys may be limited for brief periods during these site investigations, but we do not anticipate major disturbances to park use.

You can read details about the surveys and estimates for field work timing on the focus sheet linked below. If those estimates change, we will post updates here.

Blakely Harbor Park, generally located at Blakely Avenue & 3-T Road, Bainbridge Island, WA 98110, is one of several sites that have been prioritized for cleanup under the State’s Puget Sound Initiative. Between 1864 and 1922, a sawmill operated on the site. At its peak, the mill produced 100 million board feet of lumber per year. Today, Bainbridge Island Metro Park and Recreation District maintains 40 acres within the former mill property for recreational uses. Currently, the remainder of the former mill property is privately owned. 

Wood waste is present in marine sediment as a result of historic site uses. Recent soil and sediment sampling found contaminants associated with historic sawmill operations including metals, phenols, polycyclic aromatic hydrocarbons, and dioxins/furans above state standards. Additional testing will further assess the extent of contamination in the uplands and sediments. Contaminant concentrations do not currently pose an imminent threat to human health.

Ecology plans to work with Port Blakely Tree Farms (Port Blakely) to investigate soil, groundwater and sediment contamination at the site, and to develop a cleanup action plan.


Following a public comment period in early 2020, Ecology and Port Blakely have finalized a formal legal agreement called an Agreed Order. The Agreed Order requires Port Blakely to define the extent and nature of contamination in a Remedial Investigation and Feasibility Study report and to draft a Cleanup Action Plan for upland and in-water contamination.

You can watch a recording of the online open house held on March 17, 2020 to discuss the project and the early 2020 comment period, and review the comments we received and our responses in the responsiveness summary.

Investigation work to date includes:

  • Early 1990s site sampling - identified potential contamination in the former mill area.
  • 2008 - 2009 site sampling - identified potential sediment contamination at the site.
  • 2019 sediment data report - further characterized sediment contamination prompting further investigation of soil and sediment at the site.
  • 2020 sea floor characterization sampling - These surveys looked at sea floor elevation to build high-resolution bathymetric maps. They also collected images of the sediment to understand its basic characteristics and how much wood waste is present near the surface.
