By May 5, Chula Vista voters will decide whether to increase the city's sales tax rate one percentage point. The City Council approved a resolution asking voters – through a mail ballot – to raise the sales tax rate from 7.75 percent to 8.75 percent. The increase could bring an estimated $20 million a year to the general fund and would be in effect for 10 years. This would benefit public safety services in the city including Chula Vista Firefighters.
