Tracking drainage issues using GIS

Blog_TrackingdrainageissuesusingGIS.jpg

Rear yard drainage is a notable topic in Riverside these days as the
village is preparing to have some drainage studies performed. The
village has been using its GIS (Geographic Information System) program
to track drainage complaints over the past two years to realize where,
away from the Des Plaines River, residents are experiencing flooding or
drainage problems.

Imagery, elevation, and structural improvements data will be provided
by the GIS for the drainage study locations and potential solutions
will be provided by the contracted consultants. Hopefully some
economically feasible solutions will be realized and the storm drainage
for these residents will become more predictable than the weather.

Village collects LiDAR data

Blog_VillagecollectsLiDARdata.jpg

An annual process for the Riverside GIS (Geographic Information
System) program is to obtain parcel data and ownership information from
the county as they are the custodians of that data. As a part of the
2010 data exchange the village was provided LiDAR (Light Detection and
Ranging) data.

LiDAR is a remote sensing technique where laser pulses are directed
toward the earth and the time it takes for the impulse to return
provides elevation information as well as some characteristics of the
surface below. The village is currently using this information as an
elevation resource as it provides a sample point every few feet. LiDAR
can also be used to obtain a three dimensional view of an area and
potentially derive additional GIS data. This data is made available from
the county at no charge. This information is especially helpful given
that the Village does not have a previous source of elevation
information. This type of information comes into play when planning for
flooding or other elevation sensitive projects.

Improving pedestrian safety with GIS

Blog_Improving_pedestrian_safety_with_GIS.jpg

The village of Riverside GIS (Geographic Information System) program
mapped crosswalk locations in an area of town due to an event that
occurred near a school. As a result of initiating this data creation,
the remaining village crosswalks and some additional roadway striping
information were mapped to have a complete inventory of their locations
in the GIS system. Various village departments can now benefit from this
information.

The Public Works Department can track where and when crosswalks are
restriped and even give priority to crosswalks near schools and other
stripping such as at police and fire stations. The Police Department or
essentially any village department could evaluate and create a safe
routes to school system which was eligible for infrastructure
improvements funding at one time by the Illinois Department of
Transportation. The GIS system is using this currently as support
information for development of a sign inventory and can potentially
reuse this information for future projects such as creating an on-street
parking model.​

2010 Orthophotography collection

Blog_2010_Orthophotography_collection.png

As a member of the GIS Consortium the Village of Riverside
participates in an annual data collection process which allows them to
obtain remotely sensed information, or data collected from a distance.
An advantage for the community is that they receive cost savings being a
part of such a large group contracting these services. Data collection
from the past two years has provided planimetric data such as buildings,
driveways, roadways, etc. This spring the village collected a new
orthophoto. This orthophoto is a series of aerial photos that have been
geometrically corrected and referenced to remove distortions and
properly represent the location of features in the image.

A quality control procedure was conducted to check for issues
with image color, distortion, quality, shadow, and seam lines. When the
final product is provided the village will have access to a 3 inch
resolution orthophoto that will support planning and preliminary design,
map presentation, utility mapping, infrastructure alignment, provide a
historical record of development, and much more. This product is quite
improved from the other imagery available, being a 1 foot resolution
orthophoto from 2005.

Mapping local special events

Although Geographic Information System (GIS) are used to store and
retrieve data often times in a highly complex fashion, they also provide
a medium for map simple production. A special event map is a regular
request of GIS professionals and can be generated in a relatively short
time frame with good communication between the event coordinators and
the map maker.

Because the Village of Riverside has invested in a GIS program, they
are able to create many graphic products to support their day-to-day
business and community events such as the Riverside Arts Fair, Farmer’s
Market, and race events. These products provide a shared perspective and
help organize efforts for event staff and attendees alike.

Building a road inventory

Blog_Building_a_road_inventory.png

A recent development in the Riverside Geographic Information System
(GIS) has been the creation of a street inventory. Information captured
includes the type of surface material, road base material, cross section
type, curb and gutter information, last improved dates, planned
improvement dates, and other statistics that can be derived from the GIS
such as the length of roadway and even surface area could be calculated
quickly.

The street inventory is available to all staff at any time through
the Server technology that the village has invested in as well as
through the GIS. This data will provide an excellent resource for
obtaining improvement estimates and to plan resurface programs in the
long term.
