Palos Verdes Drive South Repair Discussion July 16
On July 16, the City Council will consider planned repairs to the steep section of Palos Verdes Drive South between Narcissa and Peppertree Drives, also known as the “ski jump.” The stretch spans two sub-slides in the Portuguese Bend Landslide complex that are pulling away from each other, causing cracks that have made the roadway more difficult to traverse and in need of frequent repairs.
At the direction of the Council, City staff has explored the possibility of completely re-grading the ski jump using innovative materials such as geofoam blocks, which are synthetic lightweight blocks with similar compression strength as traditional fill materials. Staff has determined this work would likely exceed $5 million, necessitate roadway closures for several weeks, and require significant maintenance due to the risk of the ski jump continuing to pull apart. Therefore, this option is not recommended at this time.
At Tuesday’s meeting, the Council will consider the recommended option to continue asphalt repairs on a regular basis, while awaiting the City’s landslide mitigation measures to significantly slow the landslide movement. Regular repaving of the ski jump section of Palos Verdes Drive South is estimated to cost $750,000 to $1 million over the course of a year.
