Passenger Trains > Landslide near La Jolla???Date: 12/10/18 20:39 Landslide near La Jolla??? Author: zuchrew Reports earlier were that Surfliners were running late because of a possible landslide. Is this still true?

In the ancient wisdom of the old SP, they built many sea walls about 20 feet high in the surf zone under cliffs that had strata sloping down to the sea. They also paid a lot of attention to drainage, keeping water out of the weak rocks and soil always helps. These measures have so far bought almost a century of reasonably well preserved right of way west of Ventura to near Surf. The slides they have experienced were at gaps in the original walls.The one exception is at Ortega (Summerland) where an old slide creeps out to the Pacific in spite of some heavy construction by the SP and Caltrans, it is simply a flowing mass of super soft soil. You can see a huge pile of rip-rap there that has only slowed down the movement.Not that there is any hope of doing that today, but perhaps a generous toe of large rip-rap along the base will slow erosion from below.https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif |
