The City of Ann Arbor Information Services Division has developed a districting application for the Department of Solid Waste. This ArcView application is built on the principles of districts and subdistricts. The Department of Solid Waste employees may use this tool to more efficiently and quickly manage the distribution and scheduling of the residential solid waste collection routes. The department's 44,805 customer accounts are aggregated within 969 tractblock polygons, and these can then be assigned to any of the five districts and thirty-six subdistricts. Based on an existing GIS database, different project plans can be created, modified, and stored. The system has the advantages of a simple mouse-driven operation, strong functionality, and can be easily adapted to other districting applications such as Voter Districts, Police and Fire Districts, etc.
