GREAT STREETS

With its thorough chronicling of building heights, tree spacing, relative widths of streets, sidewalks and cartways, this book will undoubtedly serve as a welcome reference tool for designers and urban planners. But for the lay reader, it is also an oddly poetic attempt to capture the undefinable quality that makes a street truly "great." To make his point, Jacobs, chair of the department of city and regional planning at UC Berkeley, uses text and 242 graceful line drawings to explore the magic of some 15 great streets, most of them European, including Barcelona's Ramblas, the Boulevard Saint-Michel in Paris, Via dei Giubbonari in Rome and even Venice's Grand Canal. Other well- and lesser-known examples appear in a second section comparing types of streets--boulevards, commercial strips, small-town main streets and residential roads. Finally, Jacobs analyzes those factors that make streets great: buildings of similar height, interesting facades, trees, windows that invite viewing, intersections, beginnings and endings, stopping places and, to be sure, space for leisurely walking. These are necessary qualities, but, as Jacobs warns, do not ensure a great street. "A final ingredient--perhaps the most important--is necessary . . . the magic of design."
