Design/Build Roadway Reconstruction/ Stabilization and Landslide Mitigation of Hillside Avenue

The stabilization and mitigation of the two landslides occurring along the low (south-bound travel lane) of Hillside Avenue. Each of the two landslides are approximately 100 feet long (at road) and are approximately 100 feet apart. The approximate center of the initial landslide is located approximately 600 feet north of the intersection of Hillside Avenue and Broadway Boulevard. The second landslide located approximately 750 feet north of the same intersection. This project entails stabilization and roadway restoration with an engineered repair system having a design-life of 75 years and following the local standard of care for engineering design of such systems. Preliminarily we anticipate the remedial system could include soil nails, rock anchors, shotcrete or high-strength mesh facing, micropiles, geosynthetically confined soil wall (GCS), soldier beam & lagging (SBL) walls.
