HA!  The pictured "berm" is so laughable!  How utterly unprepared these shoreline hotels are for the inevitable sea level rise, building right up to the high tide line and locating their auxiliary generator power stations in the BASEMENT for crying out loud!!!

Too bad the White House wasn't right on the beach with Carrot Face's office down in the basement facing the water.  One can only dream ...
