Your federal tax dollars funneled through the City of Manteca are paying Charlie Halyer $178.08 an hour and his fellow worker $144.88 an hour.The two are resident engineers. But they aren’t being paid that rate to make sure a freeway bridge is built safely. Instead the Caltrop employees are being paid to make sure trees and shrubs planted along the 120 Bypass corridor and part of Highway 99 get enough water.“It’s ridiculous,” said Manteca City Councilman Steve DeBrum.”I’ve got to be honest.
