Desert Ecovillage Built for the Rain

The Milagro cohousing development in Tucson, AZ, is a unique project built from scratch on a previously disturbed ridge. It features a cluster design that creates a sheltered canyon, enhancing environmental sustainability. The landscape is irrigated using rainwater and recycled wastewater, eliminating the need for storm drains. This approach not only conserves water but also provides superior flood control. The community has implemented cost-effective strategies, such as a perimeter fence to separate native and human environments, reducing maintenance and water consumption. The development serves as a model for sustainable living.
