Urban Transformation

Book excerpt: How do cities transform over time? And why do some cities change for the better while others deteriorate? In articulating new ways of viewing urban areas and how they develop over time, Peter Bosselmann offers a stimulating guidebook for students and professionals engaged in urban design, planning, and architecture. By looking through Bosselmann’s eyes (aided by his analysis of numerous color photos and illustrations) readers will learn to “see” cities anew. Bosselmann organizes the book around seven “activities”: comparing, observing, transforming, measuring, defining, modeling, and interpreting. He introduces readers to his way of seeing by comparing satellite-produced “maps” of the world’s twenty largest cities. With Bosselmann’s guidance, we begin to understand the key elements of urban design. Using Copenhagen, Denmark, as an example, he teaches us to observe without prejudice or bias. He demonstrates how cities transform by introducing the idea of “urban morphology” through an examination of more than a century of transformations in downtown Oakland, California. We learn how to measure quality-of-life parameters that are often considered immeasurable, including “vitality,” “livability,” and “belonging.” Utilizing the street grids of San Francisco as examples, Bosselmann explains how to define urban spaces. Modeling, he reveals, is not so much about creating models as it is about bringing others into public, democratic discussions. Finally, we find out how to interpret essential aspects of “life and place” by evaluating aerial images of the San Francisco Bay Area taken in 1962 and those taken forty-three years later. Bosselmann has a unique understanding of cities and how they “work.” His hope is that, with the fresh vision he offers, readers will be empowered to offer inventive new solutions to familiar urban problems.
