Prosecutors allege during trips to New York to discuss the city's bond rating, Steve Blancarte and other city officials attended Broadway plays and sporting events that had nothing to do with city business.
Blancarte, Mark Breceda, finance director Abe De Dios, and former councilwoman Rosemary Ramirez, were charged last October. Blancarte pleaded guilty to one count of misappropriation of public funds.
A judge sentenced the 56-year-old to pay $5,303 in restitution and an additional $14,700 in fines and penalties. The judge dismissed the remaining four counts of misappropriation of public funds against him.
Blanchard is barred for life from holding elective office in California.
Breceda, De Dios and Ramirez return to court on Sept. 27 for motions in the case.
