Project Description:

Record amounts of rain during the winter of 2004-2005 washed out numerous sections of the road along Hollywood Reservoir, making them impossible to traverse. Various landslides made other parts of the road impassable. Beyond just road issues, the slides affected numerous structures. Several homes on the western edge of the reservoir above the slides were red-tagged. As a result, the Department of Water & Power (DWP) chose to prevent public access to areas below due to safety concerns. The eroded slope area at the back of lots 2900, 2904 2912, 2920, and 2932 Lakeridge Drive was redone and backfilled after the installation of the soldier piles that were intended for slope control. A temporary construction access road is also shown as part of the constructability of the soldier pile installation.

VCA’s Role:

VCA Engineers, Inc. provided civil engineering services for this project, including Grading and Drainage Plans which also include roadway plan and profile, cut and fill calculations, and grade analysis along the toe of the hill to determine maximum height of wall required to maintain above slope. VCA also performed additional civil engineering services providing profile along center line of piles for the structure engineer to determine top of pile elevations, local erosion control plans, and check dams or swales at certain areas of the slope to reduce erosion during the rainy season.
