The construction of a Royal Hawaiian Groin, billed as new but encapsulating the still-intact spine of its 93-year-old predecessor on Waikiki Beach fronting the eponymous pink hotel, is pau, the state Department of Land and Natural Resources announced in a press release last week.
As a final touch, signs warning “Danger,” “Keep Off” and “No Diving” in English and Japanese were installed Aug. 13 on the 180-foot-long, 30-40-foot-wide rock rubble wall, which stands 9 feet above mean sea level at its landward end and 4 feet above mean sea level offshore.
The purpose of the new groin, like that of the slenderer, 370-foot-long old jetty, is to stop erosion of sand from Royal Hawaiian Beach, DLNR said.
