Bright red fire trucks were replaced by folding chairs and a small speaker system at the Boulder Creek Fire Department Monday as more than a hundred people gathered to hear details about a proposed rate increase for Big Basin Water Co. customers. The meeting was attended by Jim Moore, who privately owns the company alongside his wife Shirley and their son Damian, who is the chief operator of the business providing water to 547 customers in Boulder Creek. The California Public Utilities Commission was the host, as it has the authority to approve, partially approve or deny the requested increase. But it was the father-son duo who answered most of the public’s questions, which were shared via small index cards and often succeeded by spontaneous follow-up questions shouted from the live audience.
