Tuesday, April 26

  • Onboard the 4:20 p.m. sailing from Seattle to Bremerton
  • Inside the Bremerton terminal from 5:30 - 7:30 p.m.

 

  • Environmental process complete: In late 2015 the Federal Transit Administration and Federal Highway Administration determined that the project would not result in significant adverse impacts to the environment and published a Finding of No Significant Impact (FONSI)This important milestone followed the completion of an Environmental Assessment (EA) and allows the project team to complete final design work and plan for construction. The EA was informed by feedback received from the public, regulatory agencies and tribes, and was issued in early 2014.
  • General Contractor/Construction Manager selected: In 2015, WSF selected a General Contractor/Construction Manager for the project, also known as a GC/CM. The selected GC/CM team of Hoffman-Pacific, a Joint Venture, will support WSF during final design and help plan for construction. Project construction is planned to begin in mid-2017 and be completed in early 2023. A reminder that ferry service at Colman Dock will be maintained throughout construction.

Overview

Washington State Ferries (WSF), the Federal Highway Administration (FHWA), and the Federal Transit Administration (FTA) are planning a project to replace the aging and seismically vulnerable components of Colman Dock in Seattle in order to maintain ferry service in the future.

Why is WSDOT considering replacing the Seattle Multimodal Terminal at Colman Dock?

Colman Dock in Seattle is WSF’s largest ferry terminal and supports transportation across Puget Sound between downtown Seattle and communities in Kitsap County. It serves general and commercial purpose traffic, high occupancy vehicles, transit, bicyclists and pedestrians. In 2015, more than 9 million total riders traveled through Colman Dock with an additional 500,000 riders using the King County Water Taxi. This total includes over 5 million foot passengers. The Seattle/Bainbridge route is WSF’s busiest passenger route and has the largest annual ridership.

The project’s purpose is to preserve the transportation function of an aging, deteriorating and seismically-deficient facility to continue providing safe and reliable service. The project will also address existing safety concerns related to conflicts between vehicles and pedestrian traffic and operational inefficiencies.

The End Result
 
The new Seattle Multimodal Terminal at Colman Dock will improve safety by addressing concerns related to seismic vulnerability and conflicts between vehicle, bicycles and pedestrians.

Key project elements include:

  • Replacing and re-configuring the timber trestle portion of the dock;
  • Replacing the main terminal building;
  • Reconfiguring the dock layout to provide safer and more efficient operations;
  • Replacing the vehicle transfer span and the overhead loading structures of Slip 3;
  • Replacing vessel landing aids;
  • Maintaining a connection to the Marion Street pedestrian overpass;
  • Replacing the passenger-only ferry facility on the southern edge of Colman Dock with local funding from King County;
  • Mitigating for additional overwater coverage* 

WSF, FTA and FHWA will continue to coordinate closely with other Seattle waterfront projects, including the Elliott Bay Seawall Replacement project, Waterfront Seattle program, and Alaskan Way Viaduct Replacement Program throughout the design process.

*While avoidance and minimization of new overwater coverage was a key goal of the project, the new facility will increase the overwater footprint by approximately 5,200 square feet. Mitigation for this increase in overwater coverage will be achieved by removing overwater coverage from a neighboring pier owned by WSDOT.

Project Benefits

The project will:

  • Ensure that the Colman Dock facility can continue to provide, safe, reliable and efficient ferry service between Seattle and communities in Kitsap County and the Peninsula;
  • Improve safety by addressing seismic vulnerability and reducing conflicts between vehicles and pedestrians;
  • Improve existing pedestrian connections to local transit service;
  • Upgrade terminal facilities to current codes and regulations, including the Americans with Disabilities Act (ADA);
  • Remove 7,400 tons of creosote-treated timber piles from Elliott Bay;
  • Open up an area of shoreline and near-shore habitat;
  • Provide stormwater treatment for all new and replaced areas of the trestle;
  • Provide opportunities for remediation of contaminated sediments.

What is the project timeline?

  • 2012-2015 – Environmental process/preliminary design
  • 2015-2017 – Final design and permitting
  • 2017-2023 – Construction

Financial Information

$320 million dollars in federal, state and local funding has been appropriated for the project.
