In an interesting read — 🥰
Waikīkī was never a swamp. We made it into one. Then we paved over it.
Here is the part the postcards leave out.
Before the hotels, Waikīkī was one of the most productive farms in the Pacific. Not a wild marsh, a hand-built one. Hawaiians spent something like a thousand years engineering it into a vast grid of loʻi kalo (taro terraces) and loko iʻa (fishponds), fed by fresh-water springs and three streams running down from the valleys. The name Waikīkī means "spouting water." The whole system was designed to keep the water moving so it never sat still.
Kamehameha I lived here, in the coconut grove at Helumoa, the same ground where the Royal Hawaiian Hotel sits today. The chiefs surfed a break right offshore called Kalehuawehe. This was a royal seat and the island's breadbasket at the same time.
So where did the "swamp" come from?
We built that too.
After Western contact, the Hawaiian water system broke down. The taro patches were turned into rice paddies and duck farms. The streams got blocked, the water stopped moving, and it went stagnant. Mosquitoes, which were never native to Hawaiʻi and only arrived on a ship in the 1820s, bred in the standing water. The "swamp" everyone talks about was a man-made mess maybe two or three decades old. It was the symptom of a broken system, not the natural state of the land.
That distinction matters, because the "swamp" became the excuse.
In 1906, Lucius Pinkham, the head of the Territorial Board of Health and later Governor of Hawaiʻi, wrote a report declaring the Waikīkī wetlands a health hazard. The solution: drain it, fill it, build on top of it.
In 1921, Walter Dillingham's Hawaiian Dredging Company started cutting a drainage canal through the marsh with a steam dredge nicknamed the Kewalo. On paper the canal was supposed to be modest. It kept getting wider as they dug, to 150 feet, then 250.
Seven years of dredging. By 1928 it was finished. Around 625 acres of wetland were drained and buried. The three streams, the Piʻinaio, the ʻĀpuakēhau, and the Kuekaunahi, were cut off from the ocean and emptied into the canal instead.
Here is the part that still doesn't get said out loud.
Dillingham didn't just dig the canal. He sold the mud he pulled out of it as fill, to raise the land developers were building on. And he got the canal widened at public expense, because the extra dirt happened to reclaim a tract of swampland that he himself owned. He was paid to dig the hole. He was paid for the mud. And the bigger the hole got, the more of his own land turned into sellable real estate.
Land worth about $500 an acre before reclamation sold for as much as $7,000 an acre after.
The canal was supposed to have a second mouth at the Diamond Head end, which would have made Waikīkī an island and kept the water flushing. They never built it. The money ran out, and engineers worried the dirty outflow would drift right back onto the beach in front of the new hotels. So the Ala Wai dead-ends to this day, which is exactly why it still sits there like a stagnant ditch.
And the famous hotels? They did not come after the swamp was drained. They came first.
They went up on the dry sand at the shoreline while the wetland behind them was still being farmed. The Moana opened in 1901, the "First Lady," Waikīkī's first grand hotel, though smaller ones like the Park Beach Hotel in 1888 and the Sans Souci in 1893 came before her. The Royal Hawaiian, the Pink Palace, opened in 1927, while the canal was still being dug. The Hilton Hawaiian Village followed in 1955.
The canal didn't make room for the beachfront hotels. It made room for everything behind them, the avenues, the shops, the high-rises, the entire city grid, all built on fill where the taro and the fishponds used to be.
Even the sand isn't from here.
Waikīkī's natural shoreline was a thin strip of sand over bare reef. The beach you see has been barged and trucked in for a century, and it still washes away, so they have to keep replacing it. You'll hear the sand came from Manhattan Beach, California. Maybe some did, but the state's own records can't confirm it. The loads we can actually document came from Molokaʻi and other Hawaiian shores.
So when a visitor walks barefoot from a hotel toward the water on Kalākaua Avenue, a road that wasn't even called Kalākaua until 1905, before that it was just Waikīkī Road, they are walking across imported sand, over buried streams, on top of filled-in fishponds and taro terraces that fed this island for centuries.
The ʻĀpuakēhau once reached the sea right between the Royal Hawaiian and the Moana. The Piʻinaio fanned out into a delta over by Fort DeRussy and the ʻIlikai. The Kuekaunahi emptied near the Kapahulu end. All three run under the pavement now.
The Waikīkī we sell on postcards, the canal, the fill, the imported sand, the towers, is about a hundred years old.
The Waikīkī underneath it is a thousand years older.
And it was never a swamp. We turned it into one, and then we paved it.
