Working Groups

Working Groups (2009-present)


WSDOT and the King County and Seattle departments of transportation established working groups in April 2009 to help inform the design and environmental review process for the SR 99 tunnel. In 2012 we shifted the focus of the meetings to construction activities, particularly those related to the tunnel portals.

Working group objectives:

  • Review information about upcoming construction activities, schedules and potential impacts.
  • Discuss coordination between projects and how agencies are working together to minimize impacts.
  • Provide agencies with feedback on work that has been implemented.
  • Share perspectives on upcoming construction activities and proposed mitigation techniques.
  • Help distribute construction information to the broader community.

 

There are two working groups - one for the tunnel's north portal area and one for the south portal. Members represent neighborhood, business and freight interests and other interest groups. The Port of Seattle also participates in working group meetings.

 

Meetings are open to the public, and meeting times and locations are listed under public events.

In 2013, the north and south portal working groups were combined to create one stakeholder group.
