A debris-laden landslide has closed SR 706, the popular road from Ashford, Washington to Mt. Ranier National Park. The road was first closed on February 6 as portions of the highway were covered with debris up to 6 feet thick, even re-routing streams over portions of the highway. The road will remain closed indefinitely because geotechnical engineers are concerned about the stability of the saturated slopes above the highway and about what to do with the new waterways flowing over the highway. More info can be found on the WSDOT blog.
For those of you following the landslide in residential La Jolla California known as the Soledad Mountain Road landslide, it made the news again a couple days ago when a section of the slide re-activated and slid 10-ft down the hill. Doesn’t sound like too big of a deal to me, no additional houses damaged. I’m curious how it related to the shear pins they installed a couple of months ago.
Additionally, the San Diego City Attorney has released a report detailing the sequence of events leading up to the landslide. One interesting note is that the Mayor of San Diego is in hot water with the City Attorney’s office for hiring outside legal council to handle the legal aspects of the landslide. According to the City Attorney’s office, he wasn’t allowed to do that, but so far the City Attorney hasn’t stepped in to force the outside attorney(s) to drop the case saying it would open the City up to even more liability.
