San Mateo County supervisors have approved raising the base pay for regular county employees to a “livable wage” of $30 an hour.

The board, in a resolution unanimously passed Tuesday, immediately raised the base wage for more than 70 employees whose current salary steps were below $30.

“As a county of immense wealth, this is a huge step in valuing all of our employees and making sure they can continue to afford to live in our county,” Supervisor Noelia Corzo said in a press release Friday.

The board’s action aligned with what a task force determined to be a livable wage, according to the press release.

The task force determined the wage by calculating what a county worker would need in a two-income household with one child. It evaluated the cost of food, child care, health care, housing, transportation, taxes and other costs, according to county officials.
