Even before we get to next week’s first open house for the Sound Transit West Seattle-Ballard light-rail extension, it will be part of three meetings tonight and tomorrow.

TONIGHT: Added to the Southwest District Council agenda (6:30 pm, Sisson Building/Senior Center, 4217 SW Oregon), the Junction Neighborhood Organization‘s presentation on what’s known so far about the “representative alignment” (here’s our coverage of the presentation at last week’s JuNO meeting).

THURSDAY AFTERNOON: The Seattle Planning Commission will be briefed on, and will discuss, the “representative alignment” for the West Seattle-Ballard extension during its 3-5:30 pm meeting in the Boards and Commissions Room at City Hall (600 4th Ave.). Here’s the draft agenda.

THURSDAY EVENING: 5-8 pm in the board room at Union Station (401 S. Jackson), it’s the first meeting of the Stakeholder Advisory Group that Sound Transit is convening, with members appointed by the Elected Leadership Group. Its mission is explained here.
