Sumner Station Improvements

Sound Transit will improve access to Sumner Station for pedestrians, bicyclists and drivers. Improvements are expected to be completed by 2021.

1,000 people ride the Sounder Train or Express Bus from Sumner Station every day. Ten roundtrip Sounder trains stop at the station. Parking is usually full early in the morning and commuters heading to and from Sumner Station experience congestion. Sound Transit plans to provide 13 roundtrips by 2017, and predicts approximately 70% increase in ridership by 2035. As ridership and service increases, easy and reliable access to the station will continue to be important. 

 

Project purpose:

Improve access for Sounder riders to Sumner Station

  • Focusing on pedestrian and parking garage improvements within 1/4-mile
  • Focusing on parking lot, vehicle access and bicycle improvements within 1/2-mile

Project goals: 
Sound Transit has worked with city staff, community leaders and stakeholders to develop a set of project goals for the project. These goals provide a framework for developing access improvements.

  • Provide improved access to Sounder riders
  • Benefit the local community
  • Support Sound Transit's regional commitments
  • Maintain a healthy environment

Milestone: In May 2016, the Sound Transit Board selected the project to be built. Access improvements for the project include a new, approximately 623-stall parking garage at the current station parking site, including sidewalk and lighting improvements. An estimated 234 surface-lot spaces located south of Maple Street, north of Maple Street and at the Red Apple building will remain. The garage will bring the new parking total to 857 stalls, or a net increase of 505 stalls. Garage construction is scheduled to begin in 2019.

Project budget: $52.4 million

Timeline:  Garage construction begins in 2019 and will open for public use in 2021. All access improvements will be completed by 2023
