US 89 Bitter Springs Landslide Video Updates
Since I last posted about this landslide, ADOT has added several videos to their YouTube channel. It’s clear that this highway is going to be closed for the long term. ADOT and their on-call geotechnical consultant tasked with this project, Kleinfelder, are currently drilling boreholes to attempt to characterize the failure surface and determine what the geometry of the failure surface is. They are installing at least 10 inclinometers to try to determine the location of the slip plane or planes at depth and they have two extensometers to measure if any additional movement occurs. They are also performing LIDAR surveys as well. Check out the videos below.

Landslide Blocks Road in LA, Inconveniences UCLA Hoops Fans
Mud and debris from a small landslide closed a portion of Sepulveda Blvrd. In Westwood California on Thursday. The slide took out at least one local resident’s backyard and was large enough to block several lanes of the roadway with debris up to 6-ft high in addition to knocking out several power poles and disrupting service. The material was cleared up by 10pm but not before it cause some inconvenience to UCLA basketball fans on their way to watch their team beat Stanford. The LA Times reports that there were questions about possible broken water lines, of course it is the old "chicken or the egg" argument that’s been seen before (including on a recent landslide) about whether the broken water lines contributed to the landslide, or the landslide caused the water line breaks.
