TIL the cliff face at Miller's Point eroded a whole foot back in just two years from that new storm drain runoff.
Watched the survey markers from 2022 get exposed and fall off this month, which really shows how fast water can chew through sandstone when you change its path.

Look at what happened at the Marina del Rey breakwater a few years back. They changed the flow from a channel and the concrete started dissolving like sugar. Shows you can't just move water without expecting it to eat the new path of least resistance. Sandstone is basically glued-together sand, so once you give runoff a new direct shot at it, the clock starts ticking fast. Makes you wonder about all the other old drains and culverts we've forgotten about that are doing the same thing right now.
