The Watershed Management Group Co-op is helping Tucson become a greener, cooler place

It's a sunny Saturday morning, and Ezra Roati is working in his yard. A small group of people work along with him, digging, building and planting. Mounds of dirt and rock are piled high, and the sound of a power tool fills the air.
This isn't ordinary yard work. Roati and crew are "planting rain and growing shade."
