The Engineering Division is a workgroup 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, 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. Some of the Engineering Division’s services include:

  • Provide planning and engineering services for construction and maintenance projects;
  • Ensure the viability and safety of the 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;
  • Provide for the Village’s interactive mapping services (GIS)

Much of the Division’s work is 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. Questions about traffic within Winnetka should be directed to Susan Chen (847-716-3532).

Interactive Mapping (GIS)

Through its involvement with the GIS Consortium, the Village offers access to interactive maps through its website. Residents may use this tool to find information regarding individual properties, such as zoning classification, property identification numbers, or even aerial photographs. A benchmark map of the Village is also available.

The GIS Consortium (GISC) is a group of 35 member municipalities who work together to develop geographic information systems (GIS) solutions. GIS integrates maps and other geographical data for capturing, managing, analyzing, and presenting all types of geographically referenced information. GIS technology links information in diverse databases to a specific location—allowing front end users to visualize the place along with descriptive and illustrated information.

Winnetka’s interactive maps are drawn from its sophisticated computer-aided design (CAD) mapping system. This program, already operated by the Village, was the basis for GIS development. Today, the Village’s inventory based information is contained in the GIS program and CAD continues to be used for design projects.
