NEWPORT BEACH, Calif.—If you take a stroll down Newport Beach’s Balboa Island boardwalk on any given Saturday morning, as you come to Sapphire Street, you’re likely to come upon Chris Crosson, a businessman turned sandcastle guru, knee-deep in sand and water building his latest creation.
As a child, Crosson grew up on Sapphire Street, playing along the sandy shores of the man-made atoll, itself made from dredged sand pulled from Newport Harbor in 1905.
