Jonas Sparks is the Utilities Advisor in SimCity 4. His role is to advise the player on how to better manage their city's Power, Water and Garbage facilities as well as the practical side of your city's Neighbor Deals.
Jonas makes no attempt to shield his opinions of the other advisors, disliking the 'meddling' Camille Meadows, thinking she needs a 'particularly loud' Water Pump outside her office (However possibly still considering her somewhat of a friend) and regarding Monique Diamond to be a 'Buffoon'.
Jonas also shows a rather permissive view toward wasting taxpayers' money, stating that as long as Utilities are well-funded, he will ignore the Player's frequent golfing trips taken during work hours.
