Northgate Transit Center

  • This $15.8 million dollar 12 bus transit station on 4.78 acres with 300 car park-and-ride lot on First Avenue next to the Northgate Shopping Mall north of Seattle serves as a symbolic focus for a diverse and dispersed community. It features a Teflon coated fiberglass canopy roof stretching across a 255 foot platform island covering smaller, individual ornamental steel shelters marking each bus bay.

Island of light

  • The need for extended bus service to communities north of Seattle prompted the formation of a public/private joint development project for a transit center in the Northgate neighborhood of North Seattle that serves downtown Seattle, Aurora Village, Ballard, Greenlake, Greenwood, Horizon View, Wallingford, Phinney Ridge, Richmond Beach, Woodinville, and the University District.

  • Island of light

    At night when the canopy is illuminated from below, the station can be seen from a mile away.

Planning

  • Sixteen initial alternatives studied nine sites to identify the best relationships between the Northgate shopping mall and concepts for station, bus, future light rail, surface parking, and eventual structured parking improvements.

  • Circulation plan

    The planning phase aligned the team around the best location for the station.

  • Concept Scheme

    The conceptual design phase aligned the team around a long-term vision . . .

  • Concept Scheme

    . . . and tested station platform, parking, and circulation designs.

  • Four alternatives survived reviews of detailed design and order of magnitude cost estimates. Platform designs varied in bus bay layout and shelter design. The chosen alternative aligned north/south, parallel with the interstate freeway and anticipated a 1,300 car parking garage with upper level connections to a future light rail terminal.

  • More importantly, the chosen alternative stretched everyone's preconceived ideas of what a platform cover should look like. Comparing costs side by side, the station concept covered by a translucent tensioned fabric looked affordable and too irresistible to pass up.

  • Fabric translucence

    The canopy collects all bus shelters and furnishings under a single space protected from the elements.

  • Fabric translucence

    Pure white and translucent, the canopy provides shade on hot sunny days while making cloudy days feel brighter.

Design

  • The overall design organized around a "tree of life" theme proposed by the team's Landscape Architect. The canopy branches across the platform from two central steel "trees" connecting riders with maps, bus status, and trip information.

  • Teflon fabric and structure

    The teflon coated structural fiberglass fabric is free from stretching and mildew . . .

  • Trees were grown to maturity in advance of planting.

    . . . and it is held under high tension by a galvanized tube steel frame.

  • These centers gather riders from the "trunks" of two parallel pedestrian aisles originating from the "roots" of the adjacent densely landscaped park-and-ride lot. This metaphor gave rise to the artwork inhabiting the site in the form of a variety of cut and shaped cor-ten steel "critters" and terrazzo "critter pools."

Results

  • Because this project involved more public participation than most projects, it followed a well disciplined and documented approach to analysis and design. Rather than stamping the site with a cookie cutter region wide transit system overlay, the station became a unique form of art that grew out of work with the Maple Leaf neighborhood.

  • Leaning rail detail

    The Maple Leaf community actively influenced the design, structure, and choice of material finishes . . .

  • Leaning rail detail

    . . . while Metro actively contributed to station design, standards, quality, and guidelines for transit.

  • The station created an inviting and secure transit experience at any hour of day or night despite the overwhelming presence of a large shopping center, a sea of parking, a major freeway and abutting arterials. It proved highly accessible and able to withstand abuse, and it anticipated future structured parking and light rail services.

  • Glass, wood and metal detailed for caring

    Glass, wood and metal were detailed with extra care to be people-friendly, accessible, and vandal-resistant . . .

  • Glass, wood and metal detailed for maintaining

    . . . but also easy for Metro to keep clean.

  • The contractor began in early 1990 and completed the project on time for the transit center’s grand opening on May 30, 1992. In 2002, King County Metro Transit added 500 parking stalls to the park and ride lot. As anticipated, the County then joined forces with the city of Seattle, Northgate Mall management, the state Department of Transportation, the Maple Leaf Community and Sound Transit to integrate the transit center with a future super-block development that could include a new light rail station, street improvements for buses and pedestrians, a parking structure for park-and-ride use and a mixed use development with housing, cinema, retail, hotel, offices and open space.

  • Reviewed shop drawings and met with fabricators to evaluate product samples.

  • Trees were grown to maturity in advance of planting.

    Specified trees to be purchased two years in advance for a mature landscape on opening day.

    Portland Daily Journal of Commerce

    1992

    "We see here a socially-conscious project ... a holding place for commuters who leave their cars to access mass transit.

    Here they are offered an amusing and comfortable protected area, a space that addresses and pleases the user, transforming the experience of waiting for a bus into town.

    As it mellows with age and use, it'll get better."
