One of four OMFs planned for the region
Location and size supports system expansion of multiple projects (TDLE, West Seattle, and overall system expansion)
Open by 2026 and connected to active line
Very early in the planning process
A specific site has NOT been identified
Preliminary sites identified during public Early Scoping in April 2018 and project team workshops
Public comment scoping period February 19 through April 1
Existing OMF in Seattle
OMF South status
Establishing a safe, clean and comfortable ride for passengers
Link vehicles must be cleaned and stored every night and regularly pulled out of service for routine maintenance
OMFs also house staff and equipment for train operations and station and track maintenance
300+ jobs on-site; 100+ during construction
OMF overview

Needs to be located in South King County
Within 1 ½ miles of tracks Able to connection operating in 2026 (FWLE)
OMF South evaluation process*
Sound Transit Board IdentifiesSites for Study in Draft Environmental Impact Statement
Study Several Sites in Environmental Analysis
*Anticipated dates
Early scoping
April 2018; 24 sites identified
Pre-screening
July 2018; Narrowed to 20 sites
Does not meet minimum size and shape
Precludes funded roadway improvements
Regulatory constraints (cultural resources, wetlands, and sensitive areas)
Evaluation Criteria
Environmental Factors
Examples: Property impacts, street/roads (access), community impacts, wetlands & streams, Floodplains, parks & open spaces, historic/cultural, hazardous materials, noise
Physical and operational
Examples: Size, maintenance window, Light rail vehicle site access, schedule risk, operability, operating and capital estimates
Plan Consistency
ST3 Plan & Regional Transit Long-Range Plan
Results of Alternatives Evaluation
Narrowed to 6 sites
No ideal site!
Sites in Federal Way, Kent, or unincorporated King County
Sites under consideration are included in scoping
