What's an OMF?

Publish Date

Sound Transit's regional light rail system is expanding! To service and maintain additional light rail vehicles, we need to build a new facility in South King County: the Operations and Maintenance Facility South.

What does an OMF look like, sound like and mean for the neighborhood? Our project team at Sound Transit are here to answer some of these important questions about the OMF South.

OMF South Draft EIS comment period opens March 5

After almost two years of preparation, we're publishing our Draft Environmental Impact Statement on March 5, and we want your feedback. Be on the lookout for more information on the Draft EIS and how to comment coming to your inbox next week!

A Draft EIS is a major milestone in project planning. It documents the project's potential impacts and benefits to the natural and built environment for each of the three potential sites, and it also proposes mitigation measures.

Community input on the Draft EIS is crucial to helping the Sound Transit Board identify a preferred site alternative in summer/fall 2021. Following the Final EIS expected in 2022, the Board will make a final decision on the project to be built. Stay tuned!

As a note, Sound Transit Board decisions on realignment, influenced by the COVID-19 recession and increased cost estimates, may change project schedules. For more information, please visit soundtransit.org/realignment.
