12 Spiral City at Ecocity Summit 2008

A model of the 12 Spiral City was presented at the Ecocity World Summit in San Francisco in April 2008.
The 12 Spiral City is a vision of developing an ecologically integrated urban mega-structure. It applies Paolo Soleri’s concept of arcology to John Michell’s sacred geometrical plan of the Heavenly City.
Twelve spiraling ramps arrayed in a circle incorporate all the utilities and infrastructure necessary for urban living and are open to individual development of human scale habitations. At the intersection of the spiraling ramps are vertical structures connecting the levels that have large elevators that can transport vehicles as well as pedestrian traffic. It has the potential to provide a higher quality of life to its inhabitants and promote the social, cultural, and spiritual evolution of humankind, while reducing humanity’s detrimental impact on the earth.
