Geographic Information Systems

The City’s Geographic Information System (GIS) is a computerized intelligent mapping system composed of maps, data, and the tools to create, manage, analyze, and display these maps and data in a variety of ways. The GIS Department is responsible for creating and maintaining this system. GIS services include:

• Creation of new ward boundaries to better represent the Derby population
• Providing builders with information such as where a new house should connect to the sanitary sewer system
• Tracking and planning maintenance and repair of various city infrastructure
• Tracking and analyzing crimes, incidents, accidents, and citations
• Use of storm water system maps to help meet regulations as required by the EPA’s National Pollutant Discharge Elimination System (NPDES)
• Provide information to assist with the planning of proposed developments and improvements
