The mail-in vote, tallied at City Hall, came in at 66 percent in favor of helping finance the estimated $150 million project.
The vote, although only advisory, represents a necessary step to put the project on track for full funding, advocates say, because it shows federal transit grant officials that the Sacramento business community is willing to put private money behind the effort.
Advocates, including the cities of Sacramento and West Sacramento, have requested $75 million in federal funds, half the project cost, and recently received notice that the Federal Transit Administration is considering the Sacramento project for funding this year.
