 Homeowners in Seattle may soon get hit with the largest property tax increase in the city's history. Today, the full city council will vote on a $1.55 billion transportation levy. Over eight years, the money would pay for roads, bridges, bike lanes, and sidewalks. Tammy Morales wanted an even bigger tax increase. That was rejected by a committee last week during debate on her amendment. Tanya Wu said the state's tax system is already far too regressive.
