Next week, council is set to put a $1.55 billion levy on the ballot, after a push to go bigger failed to gain traction. The final size of Seattle’s next transportation levy was set Tuesday by a Seattle City Council committee, with nearly all councilmembers supporting a $1.55 billion package, but all but two rejecting the idea of going any further. Major additional amendments aren’t expected at next week’s final vote as the proposal heads toward a November vote, following two months of council deliberations to arrive at this point.
