  • October through February:
    • Finish sweeping chips from chip sealing if needed and zone sweeping. Crews are also busy sweeping leaves as well as sand throughout the county after winter maintenance.
  • March through May:
    • Street sweeping by zone. The county has been divided in nine zones for street sweeping purposes.
  • June through September:
    • Sweeping up excess chips behind the chip sealing crews.
