This is what Redwood Road was looking like before the storms. Then didn't do anything and the crack turned into this:

This would easily have been avoided by maintenance. After the first storm, the second storm caused this a quarter of a mile up the road:

Now that first picture had turned from a long crack into a slide that went down onto the golf course below. Considering the income they made from the golf course (it was full as long as there was light to see) you would think it wise to 1. not allow heavy trucks on that road that was never designed for truck traffic and 2. maintain the roads so that cracks would not allow water into the underpinning soil.
Without heavy trucks, Lake Chabot Road collapse in the storms. And that section of road was just approved by the city council to allow 60-80 heavy trucks a day on it for 40 to 80 years while the sewer department is replacing the old iron pipes with plastic.
The intention was to dump the dirt from those excavations into an old quarry that had nowhere near the capacity for that. And a road built for car traffic only on a cliff side where they allowed homes to be built.
It appears that no section of the US government has even a passing acquaintance with education and intelligence.
