Thoughts on a beach walk

Walking on the beach at Fletchers Cove. Low tide. Saw what looked like pebbles at the water’s edge. Going closer discovered they were thousands and thousands of tiny clams.
 On my right are 200 foot cliffs with houses and apartments at the top. Passing one part of the cliff that has collapsed, spewing onto the beach. 
Wondering how it would be to live there, not knowing just when the house/ apartment will be undercut and slide down the cliff.
