151 Quote by Jane Jacobs
““To generate exuberant diversity in a city's streets and districts four conditions are indispensable: 1. The district, and indeed as many of its internal parts as possible, must serve more than one primary function; preferably more than two... 2. Most blocks must be short; that is, streets and opportunities to turn corners must be frequent. 3. The district must mingle buildings that vary in age and condition, including a good proportion of old ones so that they vary in the economic yield they must produce. This mingling must be fairly close-grained. 4. There must be a sufficiently dense concentration of people, for whatever purposes they may be there...””
