(1) It's supposed to be only for infrastructure (track, stations, bridges, etc.) but there is a provision that allows BART management to use this money for salaries and administration. Read the full text of the measure here: Web Link
(2) BART already has the highest per-mile cost of any transit system in America.
(3) BART pays its employees a nation-leading average of $131,641 per year. This is in addition to pensions and liberal work rules that allow train engineers and station agents to work as little as 65% of a 40-hour week and still be paid for all 40. (BART stats courtesy of the KQED voter guide).
(4) This is a 48-year tax, at minimum. It may go longer depending on the economy.
(5) The "Yes on RR" campaign contributors can be found here: Web Link
on the Alameda County website. If you scan the donor list, you'll see that the contributions of $75,000 or more are from unions and construction firms like Bechtel.
If this was truly for infrastructure, I'd vote for it. I challenge the BART board to come up with a measure that includes protections so that my tax dollars, and those of my kids, don't go to people that are already overpaid and underworked. BART won't collapse anytime soon; the Board can rework the proposal and get it on the next election's ballot.
