Commuter Parking and Mixed-Use Development Project


The City is seeking interested, experienced, and capable property developers to design and build a development (at the old "Tully's Coffee site" -- see map) consisting of a City-owned commuter parking facility adjacent to the future Sound Transit Light Rail Station, and a desirable, mixed-use residential/commercial structure based on the City’s Town Center vision and code.

This future Commuter Parking and Downtown Mixed-Use Project is a unique opportunity to create a public-private partnership and develop an integrated gateway connection between the City’s Town Center and the light rail station’s east entrance off 80th Avenue SE (opening in 2023).

  • RFQ Process

    about 2 months ago

    The deadline for RFQ submittal was Friday, October 5, 2018 and the City received nine submittals. The City has completed a first screening of the RFQ submittals. The Evaluation Committee reviewed and selected five firms to move forward as semi-finalists. The semi-finalists were selected based on how strongly they demonstrated their qualifications, a clear understanding of the City’s goals, and an ability to work with local communities as requested in the RFQ.

    While the RFQ requested that firms provide their concept for the project, to see what could be feasible on the site, the submitted concepts are only a starting point and may or may not be included in the project. Once a firm is selected, the real work begins to design the project. A “winning” design will be developed over many months with the community being asked to weigh in on the specific features, design elements, and overall aesthetics of the project.

    The five semi-finalist firms have been invited to participate in a Community Open House meeting scheduled for Monday, October 22, 2018, from 6:30-8:30 pm, at the Mercer Island Community and Event Center. The community is encouraged to review the proposals and comment on the qualifications and concepts proposed by each of the semi-finalists.

  • Project Objectives

    about 2 months ago

    The City’s primary objective for this development is the construction of 100 or more commuter parking spaces to help alleviate pressure on the current Sound Transit-owned Park & Ride garage, that fills by 7:00am on most weekdays. Additional community benefits the City is seeking include:

    • Public Open Spaces – An attractive and functional open space and pedestrian/bicycle connection between the project site, Town Center, and the Sound Transit light rail station.
    • Well-Designed Integration – A project that integrates and enhances the Greta Hackett Outdoor Sculpture Gallery in the design.
    • Arts & Cultural Events and Spaces – Inclusion of arts performances, education and collaboration venues.
    • Housing Diversity – The community has a strong interest in adding workforce housing as well as additional condos to the Town Center area.
