Planning for sustainability is the defining challenge of the 21st century. More than any other single endeavor, it confronts the critical perils to our future, from energy shortages and environmental stress to climate shifts and population surges. That's the argument of a forward-looking new report from the American Planning Association. In plain language, authors David R. Godschalk, FAICP, and William R. Anderson, FAICP, show how cities, towns, and regions can work together to meet the challenge. These leading planners put forward eight principles for developing comprehensive plans that address today's needs without compromising the needs of the next generation. Case studies demonstrate sustainability planning at work in cities including Seattle and San Diego and smaller communities like Keene, New Hampshire, and Union County, Pennsylvania. Sustaining Places gives planners, local officials, and involved citizens a practical framework for understanding today's concerns and a roadmap for moving toward a better future. The report culminates the American Planning Association's multiyear, multifaceted Sustaining Places Initiative.
