Another sales-tax increase on the way for transportation, this time King County-wide

While the Seattle City Council reviews the mayor’s proposal to double the sales-tax share that buys more bus service from King County, their counterparts have just voted to approve a separate sales-tax increase to raise money for road repairs. The King County Council, meeting as the County Transportation District Supervisors, voted in favor of “a new 0.1% sales tax for King County that will raise approximately $100 million annually, with 87.5% dedicated to long-overdue investments in King County Roads,” according to the post-vote announcement. The rest would go to King County cities, Seattle included. But White Center and other unincorporated areas – in which the county is accountable for 1,500 miles of roads – will be the main beneficiaries.

Unlike the City of Seattle’s proposed sales-tax increase for transit, this county sales tax does not require voter approval. It will be collected starting January 1, 2027. Today’s yes votes included our area’s King County Councilmember Teresa Mosqueda, who said in a statement:

… Today’s action provides much needed relief for unincorporated roads, bike lanes and sidewalks to be built on the horizon. Whether a person is driving a vehicle, riding the bus, walking, rolling or biking – we all deserve to be safe and protected from undo injury or death due to failing roads infrastructure. Today’s vote keeps the majority of funding focused on investments in unincorporated areas while also investing in the transportation needs of our regional cities – creating a more connected, safe and accessible transportation infrastructure across our region. The measure also calls for the County to continue to pursue a robust Transit measure to complement this investment in roads with additional alternative modalities to driving.”

    this county sales tax does not require voter approval. :Why???Why not 10%?

      They’re not authorized to raise it that much; I believe state authorization is required.

      Be glad a tax for road maintenance does not need voter approval. The last time voters got to weigh in on taxing themselves for roads we ended up with $30 tab fees and not enough money to maintain roads. The remaining option is sales taxes, so now poverty-level folks are sending money to Medina and Hunts Point to further manicure their pristine pavement. I kid you not.  Read the measure. Granted, it is a trivial amount, but underlines the unfairness of sales taxes.

        You are creating a straw man argument to whine about wealthy communities (who pay sales tax) – why? You’re just making stuff up.

    I was thinking about this the other day as my bus rattled over roads that belong in a war zone.  SDOT does very little to maintain streets; instead, they favor huge projects that shut down roads for extended periods and demand huge levies to pay for them.  Meanwhile, streets get worse and worse.  Where does all the money go?  The sales tax here is so high I’m prohibited from buying almost anything that’s taxable.

      Just to be clear, this is primarily for the King County Roads Division, which is not related to the Seattle Department of Transportation and apparently has a tiny budget. Seattle might wind up with a bit of the money, though.

      Yes, would be good if Seattle winds up with a bit of the money to help repair the roads damaged by those buses. Every road/lane travelled by the buses has definite wear and tear. Roads or traffic lanes not travelled by the buses has much less wear and tear. I have friends who do shopping trips to Oregon due to no sales tax….if you have the means to make a short vacation trip consider some shopping while in Oregon.

Sorry, comment time is over.
