Picker, of Sacramento, will resign his position with the administration before joining the regulatory board, Brown's office said. He will also resign from his seat on the Sacramento Municipal Utility District board, which he won in 2012, the administration said.
Picker, 62, was chief of staff to former Sacramento Mayor Joe Serna Jr. in the 1990s and worked as an adviser to both Brown and former Gov. Arnold Schwarzenegger.
Like Brown, Picker is a Democrat. He will fill the vacancy left when former Commissioner Mark Ferron announced his resignation due to health reasons earlier this month.
The position requires Senate confirmation. It pays $131,952 a year.
