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."
This is an expression Richard Roati, Ezra's father, uses as we talk in the front yard. They are members of the Watershed Management Group Co-op, a group of volunteers who build sustainable systems in the community. Volunteers are assisted by WMG (watershedmg.org) staff members skilled in rainwater-harvesting, cisterns, greywater systems, food production and waste management.
