LOS ANGELES >> The Los Angeles Department of Water and Power’s Board of Commissioners on Tuesday approved a “customer bill of rights” backed by Mayor Eric Garcetti and criticized by some leaders from neighborhood councils, but also moved to open up public comment and revisit the bill of rights in about 90 days. The commissioners unanimously approved the provisions of the bill of rights, which includes assurances that call wait times will not exceed three minutes on average; bills that exceed three times the average historic use for the same billing period will automatically be reviewed before being sent out; and requests to start a new residential account will be processed within one business day.
