Seattle Considers Transportation Tax District
"The new taxing district, which would follow city boundary lines, could generate millions of dollars in new taxing authority.
Creating the district wouldn't require public approval, but raising sales and property taxes would.
Once a transportation district is in place, the council could raise car-tab fees by up to $20 without a public vote to fund bike and pedestrian improvements and to pay for road maintenance."
Sales and property taxes could increase, as could taxi cab fares. Toll roads could also be considered.
