I grew up in that area

And don't recall every seeing a tsunami evacuation sign like they have in Hawaii.

I do remember a sign indicating a fault line existed near my parents house. That sign is gone and houses are on / near where it was 50 years ago.

Just north of that golf course, back in the 70s A bank was broken into by a group with known mob ties. They were looking for millions that Richard Nixon supposedly had placed in the vault.
