In dollars, Seattle region's Proposition 1 was second only to Measure M, a $120 billion sales tax measure in Los Angeles County, although the comparison is lacking in at least three respects. Prop 1 did not pass in all three Puget Sound counties.

In an article updated on Nov. 10, the Seattle Times staff reported that the three-county "Proposition 1 was logging 58 percent approval in King County on Wednesday, and 52 percent in Snohomish County. In Pierce County, 56 percent of voters were rejecting the tax proposal."
Overall, in the three-county Sound Transit district, 54 percent were voting to approve.
Sound Transit declared victory on Nov. 10, though as of Nov. 18, Pierce County had counted 73 percent of ballots.
Unlike the other big transit winner on election day which called for a new half-cent sales tax and the extension of an existing half-cent sales tax, Proposition 1 was not based solely on regressive sales taxes. In addition to a half-cent sales tax, Prop 1 called for approval of:
- A property tax of $25 a year per $100,000 of assessed value
- 0.8% motor-vehicle excise tax or 'car tab' ($80 annually on a $10,000 vehicle)
The three taxes, which begin Jan. 1, 2017, are estimated to raise $27.7 billion through 2041 [25 years]. Combined with other sources, passage of the proposition will fund the $53.8 billion Sound Transit 3 plan (ST3). Per the plan's fact sheet [PDF]:
The Sound Transit 3 Plan obligates the Board to roll back taxes to the level required for permanent operations and maintenance following completion of transit projects, unless a future ballot measure directs otherwise.
According to Sound Transit, the transit plan [PDF] "will improve and expand the regional mass transit system by connecting the major cities in King, Pierce and Snohomish counties with light rail, Bus Rapid Transit (BRT), express bus and commuter rail." Note the seven Planetizen posts tagged ST3.
Proposition 1 in comparison to outcomes of other regional transit measures on Nov. 8
Unlike the four-county Detroit regional millage tax, the defeat of Prop 1 in Pierce County was insufficient to bring the margin below 50 percent, as Macomb County did for Detroit. However, The Seattle Times notes that "[t]he situation mirrors the Sound Transit 2008 vote, when Pierce County voters were alone in the three-county district in saying no."
Pierce County, pop. 843,954 (2015) with county seat and largest city being Tacoma), is the second most populous in the state after King County.
Another transit victor on election day was the progressive Indianapolis/Marion County millage tax for which stands out as being based on an income tax.
Measure M comparison
Three final points to consider when comparing Prop 1 to Measure M, the Los Angeles County transportation measure:
- Due to the infamous Proposition 13, the bar for passage of local tax measures in California is a ridiculously high two-thirds. [If state propositions required the same threshold, Prop 13 would not have passed]. If Washington had a similar tax restriction, Seattleites would not be celebrating victory.
- Unlike Proposition 1, which directed all revenue to the Sound Transit 3 plan to fund mass transit, Measure M funded costly freeway widening and local and street and road upkeep. According to a pie chart of the draft expenditure plan, 17 percent went to highway expenditure and 16 percent was earmarked for "local return" to cities to use for road upkeep [Investing in Place, pg. 6 (PDF)]
"The measure’s tax revenue also would fully or partially fund 10 new highway projects, including an extension of State Route 71 and a new carpool-lane interchange between the 405 and 110 freeways," reported Laura Nelson for the Los Angeles Times.
- Revenue for Measure M is over 40 years while Prop 1 covers 25 years.
