Lynnwood Environmental Impact Statement

On April 1, 2015, Sound Transit released the Lynnwood Link Extension Final Environmental Impact Statement (Final EIS), in accordance with the Washington State Environmental Policy Act (SEPA). The Final EIS is also issued jointly by Sound Transit and the Federal Transit Administration (FTA) under the National Environmental Policy Act (NEPA). The Final EIS examines project route and station alternatives, including the preferred alternative identified by the Sound Transit Board. The Final EIS provides information about project alternatives, potential impacts on the natural and built environment, possible mitigation measures, and responds to public comments received during the Draft EIS comment period, which ended on September 23, 2013.

The Sound Transit Board will consider the Final EIS and public and agency comments in selecting the project to be built. The Board is expected to select the route and station sites and the project to be built on April 23, 2015.

Copies of the Final EIS: Hard copies of the Final EIS are available for $25 and hard copies of the separately bound technical reports are available for $15 each. The Executive Summary and a CD including the Final EIS, appendices, technical reports, and responses to comments received on the Draft EIS are available at no charge. For copies of the Final EIS documents, please contact Lauren Swift at 206-398-5301 or or Suzan Schneider at 206-903-7445 or Copies are also available at public libraries in the project area.
