This might not be a popular viewpoint but I don't have much sympathy for high-bluff homeowners affected by slides or river-bottom homeowners affected by floods for that matter.

How was that high-bluff formed in the first place? By regularly sloughing off into the sea. How did that river-bottom get nice and flat? By regular flooding making it so. Why do they think these natural processes will suddenly stop once they build there? Duh!

OK, that said the before picture is not a real extreem case of high-bluff building and had a lot of tree re-population since the last slide that you would think would have stabilized that bank. So a little sympathy in this case. But, still, maybe you should look at the bigger picture of the topography before picking a building site.
