  • oversees private contractors to ensure that all projects meet City standards and specifications

Construction Crew

The city of Scottsdale is one of the few remaining cities that build their signals from the "ground up."  It is estimated that the City saves $20,000 per installation of each new signal by using their own crews. Three construction technicians make up the construction crew.


  • build and install new traffic signals
  • install underground conduits and loops
  • install emergency vehicle detection equipment
  • install telephone cable and interconnect wire to new and existing signals
  • provide emergency maintenance

Typically private sector contractors are either construction workers or maintenance technicians.  Scottsdale's construction crews cross train in both positions resulting in more efficient personnel and cost savings to the city.

Maintenance Crew

The Maintenance Crew consists of four maintenance technicians and one roving assistant.


  • perform preventative maintenance for over 260 city-owned traffic signals over 185 square miles
  • maintain and paint signal poles
  • assist the construction crew as needed
  • respond to signal-related emergencies

Electronic Technicians

The Electronic Technician Crew consists of two technicians.


  • set-up, test, install and maintain electronics that drive the traffic signal indications, detectors and communications
  • provide training to city staff and other signal technicians throughout Arizona through the professional organization, International Municipal Signal Association
