In 2001, FOSC partnered with the City of Oakland on a major project to restore two acres of riparian habitat along a stretch of Sausal Creek in lower Dimond Canyon.

After a contractor removed failing concrete structures, restored meanders to the stream course, and removed nonnative vegetation, creek banks were protected with bioengineering techniques and the adjacent slopes were cleared of invasive, exotic vegetation. FOSC volunteers then propagated and planted about 20,000 native plants in the canyon. In a two-year period, volunteers contributed more than 10,000 hours to this project. Work is ongoing as the Friends strive to establish natives and keep invasive plants out.

In 2017, FOSC again partnered with the City of Oakland to address erosion issues from three storm drains in the canyon. Read more about this project here.
