It is an article of faith that we design the built environment in an everchanging social, cultural, economic, technological, and ecological milieu. Contemporary urban development has responded to these changing factors in ways that might loosely be called “market urbanism.” This term is used here to refer to current conventions and modes of land acquisition, professional planning and design services, government regulation, financing, and construction for the thousands of real estate development projects that spring up in places and at times determined by macro and micro market forces and by the decisions of private developers. This market-driven redevelopment is kin to what Robert Fishman refers to as “reurbanism” in the Foreword, although his two exemplars-Battery Park City in Manhattan and Millennium Park in Chicago-are of a higher and more exalted order.
