ABSTRACT
We begin this chapter with some fundamental premises. Cities are located in bounded territories where different uses are created, mixed, and continually enhanced. Within this bounded territory, cities allow for the production of things and the conduct of social life. Human mobility, interaction, and information flow are keys to sustaining its dynamic; so too is the ability to assemble as members of one kind of community or another. Cities give meaning to anonymous spaces by converting them into what one writer calls “remembered landscapes.”1 Civitas, the polis, the agora, the neighborhood, the central business district, and the skyscraper-all sustained by a tapestry of infrastructure-endow the city with immense capacity. Because of this capacity, cities are able to continually reinvent their territories and adapt to challenges.2
