In 1983, the City of Seattle GIS began with a cooperative effort between the Engineering, Water, and City Light Departments that was mandated by the mayor's office and city council. From the beginning of the city-wide project, Seattle Water (SWD) has been a major contributor to the policy oversight, technical, and funding components of the Joint Automated Mapping Project (JAMP). The SWD has a significant stake in the satisfactory and accurate maintenance of the base map since its own database will build upon the spatial framework of the Central Geographic Data Base (CGDB). Rights-of-way, rights-of-way control lines, legal lot lines, and parcel boundary base map features are used to reference the water facilities offset dimension. The design, development, and implementation of the SWD GIS followed a structured systems development approach. This approach resulted in an inherently stable data model that will be able to evolve naturally to meet the needs of future applications. The paper describes each of these phases.
