We are a non-profit organization dedicated to reshaping cities, towns and villages for long term health of human and natural systems. Our goals include returning healthy biodiversity to the heart of our cities, agriculture to gardens and the streets, and convenience and pleasure to walking, bicycling and transit. We visualize a future in which waterways in neighborhood environments and prosperous downtown centers are opened for curious children, fish, frogs and dragonflies. We work to build thriving neighborhood centers while reversing sprawl development, to build whole cities based on human needs and “access by proximity” rather than cities built in the current pattern of automobile driven excess, wasteful consumption and the destruction of the biosphere.
