The emergency spill way is not anchored?
Astounding!
Astounding!”
I caught that gem buried towards the end of today's LAT article!!
Soft bedrock is not the only problem, he added. The concrete weir at the top of the emergency spillway was “just plopped on top of that ridge. It’s a design area that will probably get a lot of scrutiny and had to be a major concern as [the spillway] was eroding up the hill.”
Vogel confirmed that the weir, which she said ranges in height from 25 feet to 45 feet, was not anchored.
I’ve read elsewhere that it IS anchored, and that they shaved away looser rock so that they had something solid to anchor it to. I don’t think that the weir was about to slide away, but there appears that some of that rock might not have been as solid as it was thought some 40 years ago. The erosion at the parking-lot end of the weir shows that things could have gotten pretty dicey pretty fast.
