Mukilteo Multimodal Ferry Terminal

Architect: LMN Architects

Owner: WSDOT/WSF/Charles Torres

Location: Mukilteo, Wash.

This ferry terminal north of Seattle, Washington’s first in nearly 40 years, transcends its function as a critical piece of transit infrastructure, demonstrating the ways careful placemaking, engagement, and environmental awareness can reshape civic architecture. It incorporates the cultural influence of the Pacific Northwest’s Native peoples and includes sustainable elements that advance the state’s commitment to stewardship that parallels the Native ethos to “live light on the earth.”

The new LEED Gold-certified terminal occupies the site where the 1855 Point Elliott Treaty was signed by 30 different Indian tribes that inhabited the Puget Sound area, guaranteeing them perpetual hunting and fishing rights on their ancestral lands. It is the West Coast’s busiest ferry route, moving more than 2 million vehicles and 4 million riders annually. With commuter trains nearby, walk-on ridership is expected to increase by nearly 100% in the next 20 years.

A previous terminal was built in 1957, when Mukilteo had a population of just 850. That number has now swelled to 22,000. This project addresses the undersized and inefficient structure’s numerous shortcomings while also adding critical safety improvements. Designed to open the city’s waterfront to the public, the terminal meets standards for earthquake preparedness, offers more space for vehicle loading, and separates pedestrian and vehicle boarding through an overhead walkway.

Its longhouse form was born of close collaboration between the design team and Coast Salish Tribes, bolstering the passenger experience while streamlining circulation and easily handling the large flow of travelers. Inside, the terminal’s waiting room is a daylight-filled space that helps orient passengers with views of the land and sea. Works by local Native American artists are on view throughout the terminal, reinforcing the site’s strong connections to the tribal community. In addition, a new promenade along the waterfront connects with a path that winds from downtown, through the terminal, and onto the beach, creating a new elevated pathway for public use.

The project’s sustainability ambitions began with addressing the site, a brownfield that once housed a Cold War-era Air Force fuel storage tank complex. The site was originally identified for redevelopment in the 1990s, but cleanup was not completed until 2006 after artifacts discovered on the site prompted an archaeological investigation. A full array of photovoltaic panels runs along the terminal’s longhouse-style shed roof, supplying 40% of its electrical demand. In the vehicle holding area, pervious concrete filters stormwater through layers of sand before it enters Possession Sound.

In just two years after opening, the terminal has become an integral link for a number of equitable transportation modes, offering the community numerous options for traveling to and from the Seattle metropolitan area. As the first federally funded project in Washington to incorporate Native American cultural design elements, the terminal has significantly improved regional mobility while paying homage to the site’s historical context.
