Managing City Owned Property Landscaping Contracts

The City of Highland Public Works Forestry Division uses GIS to
manage landscape areas maintained by contractors. Traditionally the
primary focus was on getting bids for mowing areas. The City Forester
created a Mowing Area layer for creating maps and providing square
footage values for areas requiring landscaping maintenance to
contractors. The City Forester realized that the landscaping areas are
actually divided into two types of areas, pervious areas such as grass
and gardens and impervious areas such as parking lots and paths. Each
of these areas have different maintenance and thus contractors need to
know how many square feet pervious and impervious surface were at each
landscaping area.

The City Forester contacted the GIS Office about dividing the
landscaping areas into pervious and impervious areas to create a table
of square footages. The GIS Office accomplished this task by merging
all the impervious areas such as roads, parking lots, and sidewalks into
one area. This area was then merged with the existing landscape areas
so that now had impervious and pervious sections. The City Forester did
not want the existing landscape areas divided into separate features.
Therefore, the values from the new feature were joined to the table of
the existing feature. This provided a feature showing the entire mowing
areas that also included the impervious and pervious values of each
area.

By using GIS, the City Forester improved the accuracy of information
that they provided to contractors biding on City landscaping projects.
Without GIS the City Forester would have had to use field checks and
estimations to create pervious and impervious values for each landscape
area.
