Sprawl preoccupies US planners and citizens today, and this encyclopedia offers a clear, practical handbook of history, current issues, analytic models, and policy ideas within a general smart-growth perspective. The authors of the 22 chapters include academics, attorneys, practicing planners, and policy analysts from organizations such as Collaborative Economics and the Citistates Group; they are dominated by northeasterners, with some participation from others in western cities. The first eight essays provide contexts for the analysis of sprawl from history, law, planning, economics, politics, and social studies. Subsequent sections deal with sprawl as process, using Atlanta and the Twin Cities as case studies; models of measurement; and specific problems such as equity, environmental issues, costs, and relations to patterns of immigration and taxation. A final section looks at possible regional approaches to controlling sprawl, preserving natural resources, and promoting fair, smart growth. Useful appendixes offer Web and other resources, a glossary, and contacts with smart-growth groups….Recommended. All levels/libraries.
