Voters in Alameda County, Contra Costa County, San Mateo County, and Santa Clara County and San Francisco County will decide whether to pass the Connect the Bay Area regional ballot measure, which would create a 14-year sales tax (0.5% in Alameda, Contra Costa, San Mateo, and Santa Clara Counties and 1% in San Francisco County). The tax would generate about $1 billion annually to prevent major service cuts and improve regional transit systems including Bay Area Rapid Transit, San Francisco Municipal Transportation Agency, Caltrain, and AC Transit.
