The pandemic and our economy

The COVID-19 crisis is greatly reducing the revenues Sound Transit relies on to expand our regional transit system. Through a process called realignment, the Sound Transit Board of Directors is working to determine which plans and timelines for voter-approved projects, including Tacoma Dome Link Extension, will need to change due to lower revenue projections. Learn more about our realignment process at soundtransit.org/realignment.

Project update

TDLE is currently in the planning phase. The environmental review we began in 2019 is still ongoing, and we have developed some design refinements based on what we have learned so far. In November 2019, we shared an update on the route and station locations we are studying as well as some design concepts and visualizations (see the archived online open house ). These routes and stations are formally designated as "alternatives." In most of the corridor, the Sound Transit Board identified one alternative as their top choice, known officially as the "preferred alternative" and other alternatives to study in the Draft EIS.

In Fall 2020, we provided updates on the latest project refinements, including preliminary station concepts and ideas to improve access to the stations. We'll share more updates as we continue to make refinements.

Environmental Review 101

We are currently analyzing the TDLE project through a detailed review called a Draft Environmental Impact Statement. To begin an EIS process, the Sound Transit Board identifies the routes and station locations we should study and formally names them “alternatives.” In most of the corridor, the Board identified one alternative as their top choice, known officially as the "preferred alternative," and other alternatives to study.

An EIS analyzes and documents all these alternatives and their potential impacts to the natural and built environment, and it identifies ways to mitigate unavoidable impacts. Through this process, we consider things like effects on historic and cultural resources, residential properties, businesses, communities, the local economy and other resources.

Status of South Federal Way route and station alternatives

We are studying the following alternatives in the South Federal Way Segment:

Representative map of South Federal Way route and station alternatives. The preferred route alternative travels along Enchanted Parkway S with two station alternatives at Enchanted Parkway S and S 352nd St. Another route alternative travels adjacent to I-5 with a station alternative near S 356th St.  Both route alternatives will be elevated rails.

Learn more about the upcoming Draft EIS

An Environmental Impact Statement, or EIS for short, provides agencies, tribes and the public an understanding of a project's potential impacts to the natural and built environment, and it identifies ways to mitigate unavoidable impacts. Through this process, we analyze each alternative and design option, considering things like effects on historic and cultural resources, residential properties, businesses, communities, the local economy and other resources.

The project is now in environmental review. In the near future, we expect to publish the Draft EIS, at which time we'll also invite the public, agencies and tribes to provide formal comments.

We'll then conduct a Final EIS, which will include updates as needed, further evaluation of preferred alternatives identified by the Board following comments on the Draft EIS, and of the other alternatives considered in the Draft EIS. The Final EIS will also include responses to all public, agency, and tribal comments submitted on the Draft EIS.

After publication of the Final EIS, the Sound Transit Board will select the project to be built, informed by the EIS analyses and public, tribal and agency comments.
