Document Description
The project would install a soldier pile wall with concrete facing directly adjacent to Arastradero Road where high storm flows eroded the roadway embankment during the winter of 2016-2017. The wall would be located from 2-5 ft from the existing roadway shoulder and would be approx 100 ft long. The space between the road and soldier pile wall would be filled with clean, imported material. The pilings would be driven to a depth of approx 20 ft. Minor dewatering of the work area may be required. Clean gravel bags would be used to divert creek flows away from the work area. Construction staging would occur on the widened roadway shoulder approx 100 ft east of the work area.
