The Engineering Division is one of the four workgroups within the Public Works Department. The Public Works Director is also the Village Engineer, and this workgroup is also staffed by the Assistant Village Engineer and the Village’s Civil Engineer. The Division is responsible for providing many of the Village’s engineering services in-house, especially those related to Village streets, sewers, water, traffic, and flood plain management. This is a critical service area in maintaining the Village’s above and under-ground infrastructure. A sampling of the Engineering Division’s services include:

  • Provide planning and engineering services for capital improvement construction and maintenance projects, as directed by the Village Council;
  • Ensure the viability and safety of the sanitary and storm sewer systems, as well as the Village’s road network;
  • Review plans for construction and development projects;
  • Inspect new construction for compliance with drainage and flood hazard requirements;
  • Perform traffic engineering studies for road improvement projects;
  • Administer the flood plain management program;
  • And provide for the Village’s interactive mapping services (Geographic Information Systems, GIS).

Much of the Division’s work is internally focused on the Village’s ongoing capital improvement projects that are then carried out by other Public Works divisions—including the annual road program and sanitary sewer maintenance.

The Division’s traffic engineering work includes conducting intersection traffic control studies, monitoring of traffic signal timing, and determining appropriate pavement markings and control signs for Village streets.
