What does the future look like? Planners wrestle with this question daily as they strive to bring a community's vision of itself to life, in all its complexity. Here is an authoritative and accessible guide to a tool that combines 3-D visualization, data analysis and scenario building to let planners and citizens see the future impacts of a plan or development. The Planners Guide to CommunityViz is the first book to explain how to support planning projects with CommunityViz, GIS-based software that planners around the world are using to help decision-makers, professionals, and the public visualize, analyze, and communicate about development proposals, future growth patterns, and the outcome of particular plans or developments. It shows the planner which tools and techniques to use and how to use them for maximum effectiveness on planning projects large and small. Full of practical examples and case studies, the book shows how CommunityViz can enliven the comprehensive planning process from visioning, to public participation, to values mapping, to build-out analysis. Chapters show how to use CommunityViz to analyze zoning regulations, calculate the costs of community services, and evaluate development proposals requiring design review. In addition, it is applicable to transportation planning, natural-resource planning, land-development suitability assessment, and urban economic development analysis.
