The site is located at MPM 0.40 (near 116 Ridgecrest Drive, Napa CA). The 2017 storm events have caused a lateral movement of the slope and subsequent damage has affected 200 to 250 feet of paved roadway surface with varying amounts of horizontal and vertical displacement. The proposed repair to the slide is approximately 200' long concrete grade beam wall supported with concrete CIDH (cast in place drilled hole) piles. The grade beam depth is 4'. The piles depth is approximately 31'. There are approximately 214 linear feet of roadway payment rehabilitation (grinding and re-surfacing) and 173 lineal feet of roadway payment re-construction (removing old asphalt and replacing with new asphalt). The Engineer's Estimate is $800,000.
