Gov. Jerry Brown on Wednesday signed two bills aimed at overhauling operations of the Central Basin Municipal Water District in Commerce after years of political scandal and allegations of ethical lapses at the agency.

One of the measures, by Assemblywoman Cristina Garcia (D-Bell Gardens), will expand the district’s governing board from one of five elected members to four members elected by residents and three with technical expertise who would be appointed by water purveyors in the district beginning in 2022. It also imposes new ethics rules on the district.
