Book excerpt: This book looks at the promise of the suburban city as well as the challenges. He argues that places that grew up based on the automobile and the single-family home need to dramatically change and evolve. But suburban cities have some advantages in an era of climate change, and many suburban cities are already making strides in increasing their resilience. Gammage focuses on the story of Phoenix, which shows the power of collective action -- government action -- to confront the challenges of geography and respond through public policy. He takes a fresh look at what it means to be sustainable and examines issues facing most suburban cities around water supply, heat, transportation, housing, density, urban form, jobs, economics, and politics.
