On a Sunday morning sometime in 1904, the congregation of St. Patrick's Church in Galveston, Texas, filed into a building that was rising. Seven hundred jackscrews held the 3,000-ton structure five feet above its original foundation while, outside, a slurry of dredged sand filled the gap beneath it. Services continued on schedule.Seven hundred jackscrews. Municipal policy.
Two years earlier, a hurricane had driven a sixteen-foot storm surge across an island whose highest natural point barely cleared nine feet. Winds exceeding 120 miles per hour leveled 3,600 structures. Between six and twelve thousand people were dead. Galveston in 1900 had been the wealthiest city per capita in Texas, exporting 60 percent of the state's cotton crop, hosting every major railroad terminus. On September 9, it was a field of splintered wood and salt-crusted mud.
In 1902, an engineering commission recommended two simultaneous projects: a concrete seawall seventeen feet high, and a grade raising that would lift the entire city on dredged sand. Galveston's residents approved the seawall bond by a vote of 3,085 to 21. In a city that had just buried thousands in mass graves and trenches, near-unanimity made a kind of desperate sense. What the twenty-one dissenters saw, whether futility or expense or the sheer madness of the undertaking, went unrecorded.
The grade raising began in December 1903. Work proceeded in quarter-mile-square sections, each enclosed in a dike, roughly sixteen city blocks at a time. Within each section, everything had to go up: sewer lines, water mains, gas pipes, streetcar tracks, fire hydrants, telephone poles, fences, sidewalks. And the buildings. About 2,000 structures were lifted on jacks.
A canal twenty feet deep, two hundred feet wide, and two and a half miles long was dredged straight through the city. Homes in its path were moved and replaced after the work was done. Hopper dredges filled themselves with sand from between the harbor jetties, steamed up the canal, and discharged their loads through pipelines into each diked section. What came out was a slurry of water and fill pumped to the desired level. The water drained away. The sand stayed. It took weeks, sometimes months, to dry.
Picture what daily life looked like inside this project. You walked to work on a boardwalk fastened to the tops of the dikes, eight to ten feet above the old street level. Below you, your yard was filling with wet sand. Your trees and shrubs had been dug up and stored somewhere if you'd had the money to save them. Homeowners who couldn't afford the cost of jacking simply filled in their ground floors with dirt and moved upstairs. Five hundred city blocks. Sixteen million cubic yards of sand. Three and a half million dollars, roughly $94 million today. The last shovelful went into place on August 8, 1910.
The seawall got its test on August 16, 1915, when a hurricane pushed the tide three inches higher than in 1900. Outside the seawall, 90 percent of structures were destroyed. In Galveston, eight people died, compared with 304 elsewhere along the coast. The engineering worked. The collective will had been justified.
But the 1900 hurricane had already done its other work: confirming, for every investor weighing a dollar's placement on the Texas coast, that Galveston was a dangerous place to build. Four months after the storm, the Spindletop oil strike near Beaumont shifted Texas's economic center from cotton to petroleum. Oil needed a port. Houston, fifty miles inland and immune to storm surge, already had a congressman pushing for a deepwater ship channel. After the hurricane, his proposal gained traction it had never had. In 1902, President Roosevelt approved a million-dollar improvement project. On November 10, 1914, President Wilson opened the Houston Ship Channel. While Galveston was still spreading sand and rebuilding its wharves, the cargo vessels were learning a new route inland.
The population numbers tell the rest.
| Year | Galveston | Houston |
|---|---|---|
| 1900 | ~38,000 | ~40,000 |
| 1910 | 36,891 | ~79,000 |
| 1920s | — | 200,000+ |
Galveston's 1910 count was almost exactly where it had started before the storm killed thousands and drove thousands more away for good.
The city that performed the most dramatic physical adaptation in American urban history found an alternative economy in the 1920s. Gambling. Prohibition and lax enforcement turned Galveston into a resort town, its Open Era of vice and tourism lasting until a crackdown in 1957. Prosperity of a kind. The people who had walked on catwalks above their own filling yards had been building for a future that was already leaving them behind.
Galveston answered the question the storm posed: Can you make this island safe? Yes. At extraordinary cost and collective sacrifice, yes. Fifty miles inland, Houston was building on ground that never flooded at all, and the answer stopped mattering.
