The Sound Transit Board has awarded a design-build contract to Harbor Pacific Contractors, Inc. for the parking garage at Sumner Station. When complete in early 2026, the $49 million garage will serve Sounder S Line passengers and users of Sound Transit Express services. The 602-stall garage will provide 505 net new parking spaces at the station. Currently, the existing parking at Sumner Station is routinely full very early in the morning.
“We’re pleased to ease access to our vital Sounder service to Seattle and Tacoma for East Pierce County commuters,” said Sound Transit Board Vice Chair and University Place Councilmember Kent Keel. “Giving people more options to avoid the region’s notorious congestion along major corridors benefits us all.”
Businesses and residents in the vicinity of Sumner Station can expect more information about project progress and impacts in the spring. Early construction activities should begin this summer.
Previously, Sound Transit contributed $7.5 million for pedestrian, bicycle, lighting and ADA improvements to the Sumner Station area. That work was performed by the city of Sumner.
In addition to the contract award, the Sound Transit Board also baselined new Sounder-serving garages in Kent and Auburn for delivery in 2027.
