Former City Councilman Jim Madaffer will begin a two-year term on Oct. 1 as chair of the San Diego County Water Authority board. Madaffer, who represents San Diego on the 36-member board, was vice chair and in line to assume the top role. He succeeds Mark Muir, who represents the San Dieguito Water District. “The Water Authority is one of our region’s most important institutions, and I’m committed to continuing our long tradition of providing safe and reliable water supplies that sustain 3.3 million people and our $220 billion economy,” said Madaffer.
