The use of GIS, while not a requirement of the Study, was proposed as the ideal tool to not only efficiently address Figure 1 - Master Drainage Plan Study Area * Water Resources Engineer, Associate, Dillon Consulting Limited, 235 Yorkland Blvd, Suite 800, M2J 4Y8, Toronto, ON, Canada, Ph:, FAX: ,Ģ immediate Study requirements, but also to provide additional long-term benefits to the City - examples of this include i) the development of pre- and post-model GIS layers of infrastructure features that can be later used to advance asset management initiatives and to increase accessibility to consolidated hydraulic model results, and ii) the development of a Digital Elevation Model (DEM) for major drainage analysis that can be used for numerous visualization and analysis applications. An aggressive schedule was imposed in light of recent basement flooding that had heightened the need to identify any possible system improvements and assuage public concerns. Given Provincial regulatory requirements for Environmental Assessment, public and agency consultation was a key Study activity, requiring the presentation of findings and recommendations at Open House s and City Council meetings throughout the study. The Study Area, illustrated on Figure 1, encompasses 27 sq.km (11 sq.mi) of land within the City s boundaries, as well as external lands that drain into the City s drainage systems.
In continuing these efforts, the City initiated the City-Wide Storm System Master Plan (the Study) in 2002 to evaluate the impact of current and future development on the existing storm drainage system. The City of Stratford, Ontario, located 150 km (94 mi.) west of Toronto, initiated the development of an infrastructure asset database in the early 1990 s and continues to develop digital mapping to support the maintenance and management of municipal services.

This evolution may be attributed to the availability of continually advanced desktop software tools and an increasing amount of spatial data being established and maintained to support infrastructure planning and other municipal and resource management applications. INTRODUCTION Since the mid-1990 s, the prevalence and diversity of GIS applications in water resources management in Ontario has increased considerably, such that the use of GIS technology for data management, analysis, and presentation has evolved from a specialty service to an established, core service offered by many engineering consultants, municipalities and public agencies. The study reveals GIS to be as an indispensable, multi-purpose tool for infrastructure master planning that enables sophisticated desktop analyses, efficient simulation model pre- and post-processing, and effective data management and communication, all through the use of intrinsic functionality and readily available on-line utilities. These aspects are presented in a case study City of Stratford, City-Wide Storm System Master Plan, currently being completed on behalf of the City. Recent applications include aspects of i) data management - reviewing and editing of catchment and infrastructure data for hydraulic simulation models such as XP-SWMM and EPANET, ii) analysis - using custom applications developed for water balance analysis, or using core GIS functions such as geoprocessing, surface modelling and hydrologic analysis of major drainage systems within ESRI s Spatial Analyst extension, and iii) presentation sharing study findings with clients, colleagues and the public using thematic mapping and 3-dimensional models.
This development has occurred despite the challenge faced by users that base data (e.g., DEM s) is not as readily available as in other jurisdictions in North America. Application areas include urban infrastructure master planning for storm and sanitary drainage systems, water distribution, watershed planning, and regional groundwater protection.
