Document Description
The California Department of Transportation (Caltrans) proposes replacing a culvert system between post mile (PM) 18.00 and 18.02 on State Route (SR-) 35 in San Mateo County. The culvert system needs to be replaced to avoid pavement collapse due to culvert failure. The culvert inlet headwall on the west side of SR-35 gets filled with soil and debris and the outlet on the east side gets completely submerged, creating ponding. The outlet is 3 to 4 feet below the gravel surface and will have to be excavated to be made visible. Construction will involve trenching, cut and fill, and hydrology. Construction equipment may include, but not be limited to, excavators, backhoes, grinders, forklifts, loaders, and pavers. Some project elements will occur off the paved roadway. One way traffic control will be implemented during construction.
