Upper Drainage Erosion Control Improvements
The California Department of Transportation (Caltrans) is proposing to replace or repair drainage systems along Highway 9 from Ben Lomond to Highway 35 that have been determined to be deficient. The project would replace and/or reconstruct drainage inlets, install new pipe culverts, fill and abandon old culverts, repair outlets, place rock slope protection, rebuild and lengthen a retaining wall, and repair trail erosion.
