Interesting approach! We have organizations that coordinate food forest builds and native plant restoration events in my county, SustainableSolano.org and SolanoRCD.org . These are wonderful ways to develop permaculture skills and meet like-minded people. In addition to traditional media, Sustainable Solano also shares information on Nextdoor.com to get the word out. I am coordinating with Sustainable Solano to host a series of community events to put in a food forest garden at the elementary school where I work. One first major step is to get the school district to allow us to divert the rooftop rainwater into swales.
