"Civicorps' partnership with FOSC has let new corpsmembers flourish and it fosters newfound passions for the environment and conservation.


As a crew supervisor, I have gotten to work on several different projects with FOSC, and it brings me great joy each time I go to give back to the Oakland community."

Mary Woodall | Assistant Conservation Corp Supervisor - Civicorps

"Sausal Creek is an amazing wilderness in the heart of Oakland. And one that offers real habitat restoration opportunities!


From stabilizing slopes to restoring native plants, from removing litter to educating children, there are so many ways to contribute."

David Jaber | Climate Strategist and FOSC Volunteer

"I led a hike tour and training in Dimond Park with FOSC, and we get kids from all over the city. It’s amazing because it’s sometimes their first exposure to nature, and it’s right in their backyard.


The training teaches them about the local environment, but also gives them teamwork opportunities."

Leo Theus | Case Manager - Youth Employment Partnership

Words from our Community Partners

Letter from the Executive Director

Dear Friend,


This past year has been one of growth, reconfiguration, exploration, and action for Friends of Sausal Creek. We saw several major successes in 2023, from outplanting a record number of native plants to expanding our community of volunteers and advancing several environmental conservation proposals forward with Oakland leaders.


This is all, of course, thanks to our volunteer and donor community. Your dedication, contributions, and hard work continue to bring life back to the watershed, and we are sincerely grateful for the endless support.

As we close out the year, we reflect on the beauty of the Sausal Creek Watershed – the sound of water in Dimond Park, the majesty of the redwoods in Fern Ravine, and the marine wildlife observed in the estuary. Please join us in reviewing the many ways FOSC has made an impact this year in protecting, restoring, and engaging with the watershed and its sacred natural resources.

Lisa Giordano

Executive Director | Friends of Sausal Creek
