Overview of the Federal Way Link Extension
On December 6, 2025, Sound Transit will officially open the Federal Way Link Light Rail extension, adding three new stations—Kent Des Moines, Star Lake, and Federal Way Downtown—along an eight-mile stretch from Angle Lake in Tukwila. This extension is designed to enhance connectivity between Seattle and Tacoma, with expectations of serving between 19,000 and 24,000 riders daily. Each station will feature connections to local bus services, parking facilities, and easy transfers to regional transit options.
Current Development Landscape
Despite the anticipated benefits of the new light rail extension, homebuilding activity near the stations has been notably low. The areas surrounding the Kent Des Moines, Star Lake, and Federal Way Downtown stations are largely undeveloped, with only one housing project completed in the past decade. The lack of transit-oriented development (TOD) is attributed to several factors, including a freeway alignment that hinders potential growth and a weak real estate market in South King County.
Specific Development Projects
At the Kent Des Moines station, a 233-unit affordable housing project by Mercy Housing North is planned, alongside a mixed-use development that includes 564 units. However, the Star Lake station area has no active multifamily projects, and the Federal Way Downtown station is still in the planning phase for significant residential developments. Sound Transit is working with the City of Federal Way to develop six acres of land for potential housing, but high impact fees and a history of development moratoriums have deterred builders.
Challenges to Transit-Oriented Development
The Federal Way Link extension's alignment along I-5 has been criticized for limiting the potential for dense development. The surrounding areas, particularly near Star Lake, face additional challenges such as jurisdictional boundaries and environmental concerns, including proximity to the contaminated Midway Landfill. These factors contribute to a slow start for TOD in South King County, with only around 3,000 new homes projected in the coming years, significantly less than developments seen near other Sound Transit stations.
Official Statements & Responses
Sound Transit officials emphasize the importance of the new extension in improving transit access for residents in South King County. They are collaborating with local governments to encourage development around the new stations. However, critics argue that the current development pace is insufficient to meet the needs of the growing population and that the chosen alignment may have been a missed opportunity for more effective urban growth.
What's Next for Federal Way Link Extension
As the Federal Way Link extension opens, the focus will shift to fostering development around the new stations. Local governments and Sound Transit will need to implement strategies to stimulate housing and commercial projects to maximize the benefits of the new transit capacity. The success of the extension will ultimately depend on the ability to attract new residents and businesses to the area, transforming the currently underwhelming station environments into vibrant, transit-friendly communities.
