CommonSpace Community Land Trust of Sonoma County, a newly formed 501c3 started in 2017, is committed to providing affordable housing and ecological land stewardship in perpetuity. Exploring solutions to the housing and ecological crises in Northern California, our volunteer working group: Darryl Berlin, Katherine Yates, Cassandra Ferrera, Jerry Green and Carolyn North have envisioned a multi-generational, multi-cultural and innovative model of cooperative community in Sonoma County.

Mission Statement

      • To remove land from the speculative market in perpetuity, providing attainable access to land, quality housing, sustainable agriculture and woodland, cooperative communities and cottage industries.
      • To develop practices that steward, preserve, protect and heal the natural environment – its land, air and water.
      • To demonstrate this stewardship of the environment and attainable housing by providing information, resources, replicable models and expertise to the general public.


Inspired by the CLT communities on Lopez Island, WA and in the Bay Area, one of us purchased and donated a 3-acre property with farmhouse near Sebastopol, California with the intention of modeling an innovative life-style not dependent on owning land. Our vision is of many small household communities joining together in an extended network of such mutually dependent communities.

Five people volunteered to come together to work out the vision and logistics, and after a year of meeting, we are ready to launch:
Darryl Berlin, Cassandra Ferrera, Katherine Yates, Jerry Greener and Carolyn North.

She lives in Berkeley, California where she and her husband Herb Strauss raised their 3 children, and is the grandmother of 2 girls and 2 boys, all quite amazing young people!

Here’s to the next generation!


Katherine Yates

Katherine Yates

Ms. Yates’ lifelong interest in rural, outdoorsy living around animals, a love of design and gardening, coupled with a need to leave a career as a psychotherapist, led to the purchase in 1994 of a rural farm property in Sonoma County with multiple structures and rental units on it.
Through keeping rents affordable, selecting tenants who value community, and plowing proceeds back into the property, the place has transformed itself into a village, with rich social interactions and beauty everywhere. It is Ms Yates’ dream to replicate the success of this project, so others who share the sense of longing for something lost in our society can realize their dream to live happily in community.
