Scoping provides an opportunity to learn about and comment on the West Seattle and Ballard Link Extensions project at the beginning of the environmental review process. During this time, Sound Transit and the Federal Transit Administration are seeking input from the public, agencies and tribes.

Based on feedback gathered through the alternatives development process and the scoping comment period, the Sound Transit Board will identify a preferred alternative and other alternatives to study in the environmental impact statement (EIS). Learn more about the environmental topics to be studied in the EIS and the project purpose and need below. Then, share what you think by visiting the Comment page.
