Document Description
Caltrans District 1 proposes to correct the slide and culvert failure that occurred on SR-175 Post Mile (P.M.) 0.3. On December 26,2021 a large storm front impacted Lake County bringing heavy precipitation and snowfall. The storm caused slope saturation causing a large slip-out to develop below the roadway, resulting in separation of the culvert downdrain, further exacerbating the erosion and threatening the roadway. Caltrans proposes to repair and stabilize the embankment and repair or replace the failed culvert and/or downdrains. The drainage area that leads to the rock energy dissipator that failed in the slide will be reconstructed to stabilize the embankment.
