All in, about ~1.8bn annual budget in SF.
The Proposed Operating Budget for FY 2017 totals to $1,154.7 million[0]
The Proposed MTA FY 2015 and FY 2016 Capital Budget includes an appropriation of $562.9 million in FY 2015 and $669.0 million in FY 2016. [1]
Is that underfunded? SFMTA has massive basic accountability and prioritization problems, tons of more money wouldn't make those better.
