Mapping out Winnetka’s parkways

For many communities, the fall season is a busy time consisting of
construction projects, landscaping contracts, and other operations that
relate to the changing season. For the Village of Winnetka, this time of
year means performing weekly leaf pickup along all the Village-owned
streets as a service to Village residents. To assist the Public Works
department with their yearly leaf collection budget, the GIS department
was asked to provide the total Village-owned parkway area along these
streets as a way to estimate the percentage of leaves being picked up
that were coming from Village-owned trees versus trees on private
property.

Prior to gathering this information, the parkway areas being
considered needed to be defined. For this analysis, a parkway was
defined as the area of grass between the paved surface of a public
roadway and the sidewalk that ran parallel to the road. With the parkway
area defined, an analysis was performed using the road, sidewalk, and
parcel GIS layers for the Village to extract out all those areas along a
public roadway that were not included on a privately-owned lot. To
complete the analysis, the Village’s driveway GIS layer was used to
extract out all paved driveway surfaces where tree plantings could not
occur. The resulting layer that was created allowed the GIS department
to determine the percentage of Village land area contained within the
parkway and provide this information to Public Works.

By using some of the basic GIS base layers for the Village, the GIS
department was able to extract information on a Village-wide scale in a
fraction of the time it would have taken to gather the same land area
numbers in the field. Using the analysis tools in the GIS software saved
Village staff time and money and provided vital information that can
assist with developing more accurate leaf collection budgets in the
future.
