Public safety response

​Of all the services provided by local municipalities around the
world, public safety is arguably the most recognizable and widely
supported. Everyone wants to feel that they are safe and that someone
will respond to assist them in the case of an emergency. The Village of
Winnetka traditionally has provided fire, EMS, and police protection to
its residences since it was established, however, over the years, these
Village departments have started to provide service to additional areas
immediately outside the village boundaries through a series of public
service contracts. To assist with coordinating response efforts in these
service agreement areas, the fire and police departments asked the
village GIS department for assistance.

While several of these contracts are for police services in
unincorporated areas south of the village limits, the fire department
has the added responsibility of providing service to the Village of
Kenilworth, a small municipality located southeast of Winnetka. For
years, this area has either not been mapped or has been poorly mapped,
making it difficult to plan efficient response routes. To help resolve
these issues, the GIS department created several data layers for
Kenilworth that allow for more effective response mapping.

Since the Village of Kenilworth is not part of the GIS Consortium,
much of the base data for this area was provided by Cook County,
including roads, parcels, and an initial street address range line. The
other information used to develop this data, such as individual
addresses and street names, was provided by a combination of the
Winnetka fire and police departments. Using these two sources, a
Kenilworth street name table and an initial address database were
developed. While these two data layers do not complete the Kenilworth
dataset, they allow for additional information to be developed in the
Village database, such as a more accurate street address range feature
class.

While this service area data is being developed to assist the overall
public safety efforts of the Village of Winnetka, ultimately, the
police and fire department will use it to accomplish different goals.
For the police department, since they provide response assistance to
Kenilworth and, often, travel through the village when responding to
calls in other communities, the street address range data will be
inputted into an existing CAD (Computer Aided Dispatch) system to
provide responding officers with both village address ranges and
information on how the streets are aligned to help improve response
times. For the fire department, since they are the primary response
agency for Kenilworth, the individual resident and commercial property
addresses are critical for pinpointing the exact location of an
emergency call. A detailed map of Kenilworth, including streets, parcel
lines, and individual addresses, will be created to provide the
department with accurate property information prior to going out on a
call.

For both departments, the data developed by the GIS system will help
to improve their ability to respond more efficiently and with more
certainty regarding the location of an emergency call. This leads to
better public safety services for the Village of Kenilworth and a more
reliable system for the Village of Winnetka in responding to an
emergency event.
