Pacifica is a town built on cliffs that are not terribly resilient. The water progressively eats away at the base of the cliffs and, inevitably, things end up falling in to the ocean. I recently heard about a couple of apartment buildings that have been evacuated because of their proximity to the edge. I passed a building that had signs up in the parking lot advising you to go no further. As I got further around, I could see why. You can park there I guess but you might not have a car to come back to!
