City planner and architectural designer Speck (co-author of Suburban Nation) offers an informative and engaging look at what's gone awry in American zoning codes and road planning, and what can be done to re-engage the public with downtowns large and small. Contrary to accepted wisdom, the author says that a city center's vitality is not dependent on climate, the width of sidewalks, efficient traffic movement, showboat architecture, or cheap parking. Instead, Speck argues—and research backs him up—that cities need narrower roads, less expedition of traffic via turn lanes or one-way streets—and more mixed-use buildings, protected pedestrian areas, and trees. With covered walkways, people will hike around in any weather. Speck also recommends taking a close look at the effects of public transit and biking, and includes examples of places where one-size-fits-all transportation schemes have failed (see: Dallas). Although it's broadly accessible, Speck's comprehensive effort should appeal to architectural students, civil engineers, and local public servants. Readers will find themselves re-evaluating their home landscape and judging their own urban area through Speck's lens. What they see may shock them. Illus. Agent: Neeti Madan, Sterling Lord. (Nov.)
