Systems and testing: construction of the systems (guide wires, electronics, signaling, etc.) will occur as each segment is completed and will be completed mid-2021. Testing of the entire East Link will take approximately one-year, with revenue service expected to begin in 2023.
Operations and Maintenance Facility
In addition to the stations, Sound Transit is constructing an operations and maintenance facility in the BelRed area where light rail cars will be stored and maintained. The facility is needed to house the expanded fleet of light rail vehicles that will come with East Link. Design of the facility will complement the BelRed Corridor Plan to transform the 900-acre corridor into vibrant transit-oriented developments.
Mitigation
Efforts to lessen the impacts of the construction of light rail and the operation of the trains are known as mitigation. Mitigation is a high priority for the City Council and Sound Transit and was addressed in the planning, design and construction of the light rail being built in Bellevue. Mitigation measures are aimed at managing traffic, preserving the environment and reducing noise during construction and once the trains are running.
The 2015 MOU requires various mitigation for the East Link project and is captured in Exhibit O.

Collaborative Design Process
At the time East Link (Sound Transit 2) was approved in 2008, the City of Bellevue and Sound Transit began to work closely, through a collaborative design process to create a Regional Light Rail Transit that meets regional and city needs. A Memorandum of Understanding (MOU) adopted in 2011 between the city and Sound Transit addressed the construction, operation, and maintenance of the light rail project was amended in 2015 to address coordination of City capital projects and terms regarding the OMSF.
Members of the Light Rail Permitting Citizen Advisory Committee (CAC) were appointed by the City Council to help ensure community issues and concerns were to be addressed during the permit review process as defined in Bellevue’s Land Use Code. A great deal of public input was received at meetings and public events that helped shape the Design and Mitigation (D&M) Permits to be issued by the City.
