This Tuesday night, three West Seattle groups will meet jointly, with one hot topic on the agenda: The forthcoming West Seattle RapidRide “C Line” service. The groups are Junction Neighborhood Organization, Fairmount Community Association, and the West Seattle Junction Association, but you don’t have to be a member of one (or more) to attend, all are welcome. Reps from Metro and the city will be there to talk about routing, traffic, parking, and other effects of the new bus route. It doesn’t start running until fall 2012, but construction work for its stations/stops and other changes will start soon, and the planning work is about to hit a key phase. The meeting starts at 6:30 pm Tuesday at the Senior Center of West Seattle (California/Oregon).
