One of the directors with the Pajaro Valley Water Management Agency is suing the Agency over an 8-year-old fee on groundwater pumping. Director John G. Eiskamp filed his lawsuit this week seeking to overturn the augmentation fee after the agency won a vote for a new rate structure intended to replace the previously challenged free. Eiskamp believes the agency will not only collect the new rates but continue to bill the $80 fee from 2002 as well.
