Analyzing the Impact of Flood Control Device Installations

Over the past two years the City of Park Ridge has experienced some
severe storm events that have drastically challenged their sewer system.
In conjunction with these large events, there has also been a lot of
questioning from the City’s residents as to what they can do to prevent
storm water from damaging their home. Most of this questioning has lead
some residents to install new sump pumps, generators or other flood like
control devices; this in turn has lead the city’s Engineering
Department to wonder if these installations have helped the residents in
their fight to protect their homes.

Considering the Engineering Department originally used the
Geographic Information System (GIS) to help map out all of the major
flooding complaints from the past two years, comparing this data with
the locations of recent flood control device installations only made the
analysis portion of this project that much easier. The GIS Department
was able to take flood control device installation data from the city’s
permitting application and map this data out quickly and accurately.
Once the data was mapped, the GIS Department was then able to perform
multiple spatial queries in order to review where flood control devices
were installed in comparison to where residents complained of flooding.
The output of this analysis was a statistical spreadsheet that has
directly helped the Engineering Department understand if flood control
device installations are actually helping to reduce the amount of
flooding to a specific residence. In addition, it has allowed the city
staff to gain more input on what may be working to combat these flooding
problems so that they may make recommendations that are more accurate.
