Draft EIS

Sound Transit and the Federal Transit Administration (FTA) have published a Draft Environmental Impact Statement (EIS) for the Everett Link Extension.

Public review and comment period

Now through Nov. 2 is your opportunity to review and comment on the Draft EIS during a 45-day public comment period. Your feedback directly shapes the future of the regional transit system. The FTA and Sound Transit encourage Tribes, agencies, and the public to comment on the alternatives, environmental findings, and potential mitigation measures detailed in the Draft EIS. We want to understand your priorities for the different route, station, and Operations and Maintenance Facility (OMF) North alternatives. After the comment period, the Board will identify, confirm, or modify the preferred alternative based on information in the Draft EIS and input from Tribes, agencies, and the public.

What is an EIS?

The Draft EIS compares different routes, stations, and OMF North alternatives . The document considers how the alternatives might affect transportation systems, the natural and built environments during both construction and future operations, and nearby communities.

As we continue to advance project design and our technical analysis, the design will continue to evolve and change. As part of a workplan to improve the agency’s financial situation, we are exploring opportunities to reduce costs. This may include changes to station design, highway crossings, and the final list of affected properties.

The Draft EIS is the first of two EIS documents. The Final EIS, expected for publication in late 2027, will:

  • Respond to substantive public, Tribe, and agency comments.
  • Include any necessary revisions to correct technical errors.
  • Incorporate relevant new information that became available since the Draft EIS was published.

What is studied in the Draft EIS?

Based on current federal regulations and executive orders, the Federal Transit Administration and Sound Transit address the topics below in the EIS:

  • Acquisitions, displacements, and relocations.
  • Air quality.
  • Economics.
  • Ecosystems.
  • Electromagnetic fields.
  • Energy.
  • Geology and soils.
  • Hazardous materials.
  • Historic, cultural, and archeological resources including Section 106 (National Historic Preservation Act) resources and process.
  • Land use.
  • Noise and vibration.
  • Parks and recreational resources.
  • Public services, safety, and security.
  • Section 4(f) of U.S. Department of Transportation Act.
  • Social resources, community facilities, and neighborhoods.
  • Transportation (traffic, freight, navigation, aviation, transit, non-motorized).
  • Utilities.
  • Visual and aesthetic resources.
  • Water resources.

To address state requirements, Sound Transit also addresses indirect impacts, cumulative impacts, and greenhouse gas emissions in an Appendix to the Draft EIS.

How to review the Draft EIS

The Draft EIS is available for public review in a variety of formats to help make your review easier. You can review:

We recommend focusing your review on the key sections that matter most to you and taking notes as you go. The Draft EIS table of contents below can guide you to the topics you care most about. Reviewing Chapter 2: Alternatives Considered in the full Draft EIS will help you learn about the station areas and alternatives we are studying with written descriptions, maps, and graphics.

Executive Summary

The Executive Summary shares a high-level summary of the Draft EIS contents, sections, and areas of study.

Draft EIS

Full Draft EIS document, including the Draft EIS cover letter, signature page, fact sheet, table of contents, and the below chapters and appendices:

Chapter 1: Purpose and Need
States what problems the project will address and why the investment in this transit project is needed. This section also includes the project timeline.

Chapter 2: Alternatives Considered
Describes the alternatives evaluated in the Draft EIS, including alignment , station, and OMF North site locations. This section includes how the alternatives were developed, how they will be constructed, how long construction will take, and information about the stations. Additional information about other alternatives considered in earlier phases of the project can be found in Appendix B.

Chapter 3: Transportation Environment and Reasonably Foreseeable Effects
Describes how existing transportation infrastructure would be affected and potential effects of the project related to the regional transportation network, arterial and local streets, parking, non-motorized transportation, safety, aviation, and freight.

Chapter 4: Affected Environment and Reasonably Foreseeable Effects
Discusses the affected environment and potential effects of the project related to the following resources: acquisitions , displacements and relocations, land use, economics, social resources, community facilities and neighborhoods, visual and aesthetics, noise, vibration, water resources, ecosystem, public services, safety and security, historic and archaeological resources, and parks and recreational resources.

Chapter 5: Potential Mitigation Measures
Discusses how Sound Transit is complying with all applicable federal, state, and local environmental regulations and following best management practices. Sound Transit is designing Everett Link Extension in a way that avoids or minimizes adverse impacts where possible, and applies mitigation measures as needed. These measures are detailed in the technical reports in Appendix G.

Chapter 6: Significant and Unavoidable Adverse Impacts
Lists the long-term permanent impacts of the project that may not be fully mitigated by the measures described in Chapter 5.

Chapter 7: Tribal, Agency, and Public Involvement
Describes Sound Transit’s work with Tribes, neighborhood and community stakeholders, local transit partners, and city, county, state, and federal agencies.

Chapter 8: Areas of Controversy and Issues to be Resolved
Lists a handful of issues that remain to be resolved throughout future project phases.

Chapter 9: Next Steps
Details next steps for the project following publication of the Everett Link Extension Draft EIS.

Other Draft EIS resources

What happens next?

After the Draft EIS comment period closes on Nov. 2, we’ll compile and evaluate comments and provide a summary to the Sound Transit Board and the public. Then the Board will confirm, modify, or identify a preferred alternative, which we will evaluate along with other alternatives in the Final EIS.

Environmental review will continue through publication of the Final EIS, which we expect to happen in late 2027. Environmental review ends when the Federal Transit Administration issues a Record of Decision. The Sound Transit Board will select the project to be built, which is their official decision about which route, stations, and OMF North location to build.

Early 2027

  • Sound Transit Board confirms, modifies, or identifies Preferred Alternative.

Late 2027/Early 2028

  • Final EIS publication.
  • Federal Transit Administration issues Record of Decision.
  • Sound Transit Board selects the project to be built.

2028

  • Begin final design.
