Virtually no one here in this deep-blue state denies the serious risk climate change poses to the islands, and there is widespread acknowledgement about the need to the preserve the $7 billion in economic activity that Waikiki generates annually.
They also steer right into some of the thorniest questions cities face today as they try to plan for costly realities that lie years, not just decades, ahead. These ideas, if implemented, seek to save Hawaii’s most popular attraction, located on the island of Oahu, by totally reimagining it. If no action is taken, 6 feet of sea level rise would put Waikiki permanently under water.Īs a result, some in Honolulu are envisioning far more radical solutions than groins - hollowing out the first few floors of buildings, for example creating a Venetian-style canal system or turning Waikiki back into the wetlands it once was.
At high tides, water already sloshes out of some storm drains and pools in below-ground parking garages. As the ocean expands, water is expected to seep into Honolulu’s porous limestone geology, nudging up the water table and eventually inundating Waikiki’s dense thicket of roads, hotels, restaurants, shopping malls and condo towers. Neither will the rest of Waikiki’s 1.5 square miles beyond the beach, at least not in their current form. “We’re buying time,” admits Eversole, who also works for the University of Hawaii. When this happens, today’s projects will seem futile. Studies and modeling show that the combination of thermal expansion and melting polar ice will cause a global, 3.2-foot sea level increase sometime between 20, resulting in twice as much coastal erosion in Hawaii as there would be otherwise. The group’s next phase of work calls for more of the same: Spending at least $50 million, much of it likely from state and perhaps federal funding, on four more groins and the construction of an entirely new beach in the area fronting the Sheraton, Outrigger Reef and Halekulani hotels.īut reengineering the beach in the future is only going to get harder. Near the pink, 94-year-old Royal Hawaiian hotel, the association (in partnership with the state) recently built a $1.8 million groin - an L-shaped finger of rock and concrete that juts into the water and holds sand in place - in addition to widening the beach by 30 feet with 20,000 cubic yards of sand vacuumed up from the bottom of the sea. The hotels along the beach are worth north of a billion dollars, and to preserve that investment, hotel owners and other businesses fund the Waikiki Beach Special Improvement District Association as a kind of coastline-repair department.
Like many places buffeted by the ocean, Waikiki has swung into action - to a point. At the Outrigger Reef hotel, ocean water laps directly against the wall of the new Monkeypod Kitchen restaurant, still under renovation. Just below the infinity pool at the Sheraton Waikiki, an advancing shoreline claimed a walkway and set of concrete stairs, which now dangle above the water. But for years, Honolulu and the State of Hawaii have been reckoning with a very uncomfortable fact: The beach is vanishing. HONOLULU - Waikiki might be one of the most famous beaches in the world, a synonym for surfing and sun-soaked vacations that draw millions of people annually.
