CHULA VISTA, Calif. (KGTV) -- Chula Vista residents will head to the polls in June to decide whether or not to pass a new sales tax. Measure A would increase sales tax in the city by half a cent, tying it for the highest sales tax in San Diego County. If passed, the city estimates the sales tax will generate approximately $17 million per year. City leaders say the tax will be used for public safety and those in favor of the tax increase say it’s much needed.

Supporters of the tax also say the city needs more firefighters to be more efficient. Those against the measure point out the fact that, though leaders say the money will go to public safety, the text of the measure says the proceeds “shall be for unrestricted general revenue purposes.” In other words, the money can be used for any lawful purpose.

The measure goes to the voters during the June 5 primary.
