White Sulphur Spring Rd Slide Repair

County of Napa, CA / Public Works

Description

The White Sulphur Spring Road Project consists of the construction of a 192-foot-long, 10-foot-high soldier pile retaining wall where significant settlement and damage occurred at the slide in order to prevent future slides and improve the steep slope stability on the south side of the road along the roadway edge. The structural steel soldier piles are embedded in 30-inch diameter holes filled with lean concrete. The cast-in-drilled hole piles are spaced at 8 feet on center, with precast concrete lagging installed between the piles to retain the slope. Relatively closely spaced soldier piles will transfer lateral soils loads to deeper and stronger materials. Filling and repaving the roadway will be required to restore the asphalt surface and pre-slide drainage patterns.
