The future isn't always what we plan for. This presentation will focus on how GIS was used to help the City of Phoenix develop a strategic water supply and water infrastructure master plan by examining the potential impacts of alternative land use scenarios on water supply and water infrastructure needs. The alternative land use scenarios that were modeled were developed based on hypothetical future headlines, like Valley Manufacturing Moves Overseas, Climate Changes Affect Tourism and In-Migration. For each headline, changes in economic, demographic and technological trends were identified and translated into land use impacts. GIS was used to develop growth, population, and employment scenarios for each alternative future from which water demand and the locations for the alternative water infrastructure could be projected. The presentation will include a discussion of how these land uses were modeled, the findings, and methodology for integration into the water models.
