This article is taken (with permission) from the SaveSutro.com website. It says UCSF’s Plan for Mount Sutro – which could start as early as this winter – could directly increase the risk for our neighbors on Christopher and Crestmont.
I started thinking about it. It’s a pretty insidious. The cutting of trees, and widening of the road to use heavy machinery and trucks up above our neighborhood could have very long-lasting effects – for five to ten years after the project, according to the research. Nothing might happen immediately – and then along comes a really wet stormy winter and whoosh!
Is this something real estate agents will have to disclose? I don’t know. And if something does happen – what’s the insurance situation? (I’m not even going to think of the risk to families living there.)
Anyway, this article is to let our Crestmont and Christopher neighbors know about these concerns. There’s more about the UCSF 2017 Plan on SaveSutro.com
Recently, we wrote that the Sutro Forest 2017 Plan Imposes a Landslide Risk. A University of Washington study shows that mudslides are most like 5-10 years after trees have been cut down on slopes. The picture below shows the South Ridge, which will be directly affected.
But it’s not just the tree-cutting. UCSF is widening two major trails into roads fit for heavy equipment, and adding nine quarter-acre “staging areas” for machines and felled trees. Both the roads are above Forest Knolls. (The heavy yellow lines in the map below are the new roads. The red squares are the locations of the staging areas, each of which will be a quarter acre.)
The picture at the top of this article gives some indication of how steep the hillside is. And the roads above Forest Knolls are atop a slope *known* to be unstable. Look at this landslide hazard map:
The double black arrows show landslide direction. The wiggly black arrows show soil creep direction. All those dark green areas? Potentially unstable. All the gold areas? Also potentially unstable.
Though the Draft Environmental Impact Report claims it’s making safety its first priority – it doesn’t look like it. In attempting to mitigate one (overstated) concern (dead trees falling), they’re worsening the risk of landslides.
