What to Expect

Traffic Control

  • During construction, temporary traffic control devices will be in place to direct traffic in the work zone.
  • There will be temporary lane closures in the work zone, but access will be maintained to all residences during construction.
  • Temporary no parking signs may be posted in the work vicinity.
  • There will be open excavations at times. Caution should be used in the vicinity of the construction operations.
  • Street closures are not anticipated at this time.

Water Service Interruptions

  • Area residents whose water service may be interrupted during the project will be notified one day in advance with a bright orange door hanger on the front door.
  • Service interruptions take place between 8:30 a.m. and 3 p.m.
  • Intermittent discoloration of the water sometimes occurs during construction due to water surges which loosen particles inside the old main and service pipes. Let your cold water run 10 minutes or until the water clears.
