Project Goal
As with most government bodies, the city’s business is primarily location-based, from addresses (calls for emergency services, service requests), to infrastructure (to build and maintain).
The city of Naperville’s goal when it began its implementation of GIS in 1994 was to build an enterprise wide system to share data associated with locations from its many systems, improve the quality and efficiency of city services, and enhance decision making processes.

Business Problem Solved
With GIS, city of Naperville staff now views its geographic information as a common resource that can be shared throughout the organization. Prior to GIS, city departments that created maps maintained separate land base information, such as parcel lines and addresses, for their own use. The result was redundant (and often conflicting) geographic information maintenance among the city’s departments. Now one department maintains and disseminates common GIS data layers throughout the organization and all city maps and geographic data, regardless of the department, have a common, consistent accuracy.
With the development of an enterprise GIS each city department now maintains and has access to a complete geographic inventory of its own assets. This is especially important to the city’s electric, water, and wastewater utilities which use GIS to model the systems which provide critical services to Naperville citizens.
As one of the fastest growing cities in the country, the city’s Community Development Department needed access to key zoning and land use information. With the creation of a detailed cadastral database the GIS was utilized extensively to help guide development during the time of the largest commercial and residential growth in the city’s history.
Technology Implemented
Throughout its implementation of GIS, the city has used nearly all of ESRI’s technology. During the initial deployment ArcInfo 7.0 was installed on several UNIX workstations around the city and ArcView 2.0 was used for data viewing and query.
At ArcView 3.0 an application was developed using Microsoft Visual Basic and Avenue for editing and maintenance of the cadastral database. It accessed spatial and attribute data with SDE 3.0 running under Oracle.
The City embraced ESRI’s object technology at the release of MapObjects 1.0. Along with the integration of GPS technology, MapObjects was used for the deployment of mobile applications for the maintenance of street signs, streetlights, and pavement markings.
ArcIMS has been used for several Intranet and Internet applications, which have made it possible for the city’s extensive GIS data to be queried and mapped by an increasingly large audience.
Finally, the city has worked with technology from key ESRI business partners over the years. These include Miner & Miner, whose ArcFM Energy software has enabled the city’s electric utility to be proficient users of GIS technology. In addition, Azteca Systems software, including their ArcGIS-based Cityworks maintenance management software and MapObjects-based Call Center have been major components of the city’s enterprise GIS implementation.
Development Team Biography
Many staff members have been involved with the city’s GIS program since its inception. Most notably this includes the city’s Director of Information Technology, Don Carlsen who spearheaded the decision to implement GIS. One of Mr. Carlsen’s first steps was to hire Nancy Place as GIS Manager. Ms. Place was responsible for the initial implementation which included selection of a consultant to provide a comprehensive GIS planning study.
Larry Gunderson succeeded Nancy Place as GIS Manager in 1994 and Walter Stronczek was brought on as a GIS Analyst the following year. Both Gunderson and Stronczek continue to play key roles in the city’s GIS program, with Gunderson responsible for overall management and coordination and Stronczek the technical system architecture and database development lead. Key applications have been developed by Gabe Conrad, Kurt Roloff and Steve Gartner. Sarah Jenniges, Kristi Carlson and Joseph Renzetti have provided database management and systems support.
While most of the GIS program has been coordinated through the Information Technology Department, several staff throughout the city have played major roles in the implementation. These staff include Debbie Kresl from Engineering and Development, and Jim Kivela and Jessica Putra of the Department of Public Utilities.
