Measure Q, similar to Measure R, was approved on November 4, 2008. It received a combined vote of 69.5% in the two counties (73.5% approval in Sonoma County and 62.6% in Marin County). It provides funding for the project through a quarter-cent sales tax in both counties set to expire in 2029. This funding was initially thought sufficient to bring the line to completion by 2014. However, the economic downturn reduced the tax base, resulting in a plan to build the project in phases. The tax was expected to generate $890 million over its lifetime; the first decade brought in $289 million, well short of estimates.
