The San Diego Association of Governments wants to put a tax increase on the November ballot. The measure proposes a half-cent sales tax increase on county residents to fund transportation and infrastructure around the county for the next 40 years.

The proposed tax hike already has a number of critics. It’s being opposed by environmentalists and community leaders who don’t like the way the money would be used. About 40 percent of the money would go toward public transit, according to the proposal, including things like a new trolley line from San Ysidro to Kearney Mesa and improvements on existing bus services.
