Repairs to North 4.5-Mile Section of Sawyer Camp Segment Begin Soon
Work to address the unstable ground that is undermining the trail, remove landslide debris, and restore sections of the Sawyer Camp segment could begin as early as mid-September.
San Mateo County Parks and the Department of Public Works will soon select a contractor with the expertise needed to lead this complex project and apply for required permits. Contractors will also reestablish drainage and replace damaged culverts. The intent is to reopen trail sections once they are repaired and inspected while work continues elsewhere along the trail. It is difficult to predict when full trail restoration will be completed.
While the County is pursing Federal Emergency Management Agency reimbursement for this effort, the project will move forward using San Mateo County Measure K funds to cover costs so the trail can safely open to public recreation.

Sawyer Camp Trail was one of several San Mateo County Parks severely impacted by storms in early 2023. Beyond flooding and downed trees, the trail sustained extensive damage in multiple areas that have been inspected by geotechnical engineers. The northern 4.5-mile section of the segment remains closed.
