All around the world I see water wastefully flowing down and out of urban street curbs and concreted storm drains even though it has not rained in months. It is not stormwater I see flowing. It is urban drool. Others call it “nuisance runoff” – water from leaky pipes, driveway car washes, overwatered landscapes, and so on – our waste. But it can be a resource. It can be harvested.
That is what is happening in Los Angeles, California long a mile long stretch of the Tujunga Wash Flood Control Channel, between Vanowen Street and Oxnard Avenue. It is bringing myriad life back to this community.

![]() Fig. 24.The heat island effect. An excessively wide, exposed, solar-oven-like residential street in Tucson, Arizona absorbs the sun’s heat during the day like a battery, then radiates it out at night. This local warming effect has raised summer temperatures in Tucson by 6°F (3°C) since the 1940s, which contributes to global warming since the higher temperatures result in people using air conditioners more, which are powered by electricity generated through the burning of coal. Note that no shade trees are planted in the public right-of-way along the street, leaving street and sidewalk baked. All runoff is drained off site leaving the development dehydrated.

My view of public streets was radically changed when I heard ecovillage designer Max Lindigger tell a story of an insightful walk he took with his grandfather. “Look there,” said his grandfather, pointing to condominiums being built on the once forested slopes above his village in the Swiss Alps. “That’s where we grew and gathered food during the war. The forests were common land, a reserve of community resources. What commons remain? Where will we grow and gather our food in the next catastrophe?”
I then looked at my Sonoran desert city of Tucson, Arizona and asked myself, “Where are my community’s forests, our commons? Where would we get our food in times of need?”
