Urban sprawl, spreading across the landscape, causes enormous waste, frustration, and long-term costs by depleting land and resources. Dependency on the automobile intensifies these problems, while increasing pollution, congestion, and social isolation. Arcosanti attempts to address these issues by building a three-dimensional, pedestrian-oriented city. Because this plan eliminates sprawl, both the urban and natural environments keep their integrity and thrive. Arcosanti is a prototype: if successful, it will become a model for how the world builds its cities.
Overall, arcology seeks to exemplify a “Lean Alternative” to hyper-consumption and wastefulness through more frugal, efficient and intelligent city design.
“Arcology is capable of demonstrating a positive response to the many problems of urban civilization, those of population, pollution, energy and natural resource depletion, food scarcity, and quality of life. The city structure must contract, or miniaturize, in order to support the complex activities that sustain human culture and give it new perception and renewed trust in society and its future. A central tenet of arcology is that the city is the necessary instrument for the evolution of humankind”.
-Paolo Soleri, Earth’s Answer, 1977
