Erosion Repair Work Begins Along Crystal Springs/San Andreas Pipeline

Map of Erosion Repair Locations

Repair of erosion damage along the Crystal Springs/San Andreas Pipeline adjacent to Sawyer Camp Trail is underway at two locations. The project has an accelerated time line to facilitate completion prior to fall/winter rains. The Trail will remain open throughout the construction process.

The contractor will remove the loose soil from the erosion sites, then compact a stable surface to hand-place interlocking concrete blocks to create a matrix. The blocks also will be connected by cables to hold them in place.

Hikers should be vigilant as construction vehicles will need to use Sawyer Camp Trail to convey workers and supplies to the construction sites. There also may be some weekend work. Construction is expected to be completed in December.
