OMF South project to be built is selected
On June 27, 2024, the Sound Transit Board selected the South 336th Street Alternative in Federal Way as the project to be built for the Operations and Maintenance Facility (OMF) South. The Final Environmental Impact Statement (EIS) and its findings, public and agency comments on the 2021 and 2023 Draft EIS documents, and other factors informed this decision.
A recording of the June 27 Sound Transit Board meeting is available here.

Next steps
We anticipate the Federal Transit Administration to issue a Record of Decision later in 2024 under National Environmental Policy Act. With that, the project will begin final design. Construction is expected to start in late 2024/early 2025.
The Board has identified a target in-service date of 2029. The agency is working to accelerate the current schedule to achieve that date.
What’s an OMF?
An OMF is where Link light rail trains go for cleaning, storage, and maintenance, 24 hours a day, 365 days a year. Sound Transit needs four strategically located OMF facilities. Sound Transit must construct a new OMF in the South Sound to receive, store, and service a large train fleet to support future light rail extensions throughout the region. Building this new facility requires approximately 60-70 acres (for reference, one football field is 1.3 acres) near the Federal Way Link Extension.
