Document Description
In January 2023, the Peninsula Corridor Joint Powers Board (JPB) conducted a field survey to inspect the San Francisquito Bridge condition for any damage that might have occurred after the major January heavy rain and rising levels in the creek. This field survey revealed that the north bank abutment slope protection below the railroad bridge bearings was severely scoured and undermined the existing soil protection to the bridge north bank abutment. The survey also found that the roots of trees near the north bridge abutment bridge have been exposed, making the tree unstable as well as soils scour surrounding a storm drainage pipe outfall structure located 50 feet downstream of the north bridge abutment. JPB concluded that north abutment soil slope stabilization measures will need to be implemented before further erosion undermine the north bridge abutment. The project involves stabilization measures of the embankment below the JPB bridge, surrounding the existing storm drain outfall, and below the Alma Street bicycle-pedestrian bridge located approximately 60 feet downstream of the JPB bridge.
