SURFSIDE, Fla. – For four decades, the Champlain Tower South condominium sat about 100 yards from the sea, much of that distance covered by sand. During that time, the tide ebbed and flowed toward the building nearly 60,000 times. A full moon rose in the sky 500 times. The condo witnessed it all.

Then, on Thursday, it was gone.
