The people that will be most affected by a “greater Cedar Rapids” were staying home, or were still coping in FEMA trailers where the water pipes routinely burst in the harsh Iowa winter, or were living with relatives, or had simply disappeared and moved on or given up. They had sold their flooded houses for a song or had taken out a mortgage at the age of seventy. They were buried under massive mounds of bureaucratic paperwork, trying to get a check so they could rebuild or relocate. They were scrubbing the mud off their ruined homes. Their neighborhoods were gone. Their nerves were frayed. Their hearts were forever broken. This book is mainly about them—the people who did not attend the one-year commemoration—and why they stayed away. The people who had nothing, absolutely nothing to celebrate because everything had changed.

In the early days of 1937, the Ohio River, swollen by heavy winter rains, began rising. And rising. And rising. By the time the waters crested, the Ohio and Mississippi had climbed to record heights. Nearly four hundred people had died, while a million more had run from their homes. The deluge caused more than half a billion dollars of damage at a time when the Great Depression still battered the nation. Timed to coincide with the flood's seventy-fifth anniversary, The Thousand-Year Flood is the first comprehensive history of one of the most destructive disasters in American history. David Welky first shows how decades of settlement put Ohio valley farms and towns at risk and how politicians and planners repeatedly ignored the dangers. Then he tells the gripping story of the river's inexorable rise: residents fled to refugee camps and higher ground, towns imposed martial law, prisoners rioted, Red Cross nurses endured terrifying conditions, and FDR dispatched thousands of relief workers. In a landscape fraught with dangers—from unmoored gas tanks that became floating bombs to powerful currents of filthy floodwaters that swept away whole towns—people hastily raised sandbag barricades, piled into overloaded rowboats, and marveled at water that stretched as far as the eye could see. In the flood's aftermath, Welky explains, New Deal reformers, utopian dreamers, and hard-pressed locals restructured not only the flood-stricken valleys, but also the nation's relationship with its waterways, changes that continue to affect life along the rivers to this day. A striking narrative of danger and adventure—and the mix of heroism and generosity, greed and pettiness that always accompany disaster—The Thousand-Year Flood breathes new life into a fascinating yet little-remembered American story.

Flooding is the natural hazard with the greatest economic and social impact in the United States, and these impacts are becoming more severe over time. Catastrophic flooding from recent hurricanes, including Superstorm Sandy in New York (2012) and Hurricane Harvey in Houston (2017), caused billions of dollars in property damage, adversely affected millions of people, and damaged the economic well-being of major metropolitan areas. Flooding takes a heavy toll even in years without a named storm or event. Major freshwater flood events from 2004 to 2014 cost an average of $9 billion in direct damage and 71 lives annually. These figures do not include the cumulative costs of frequent, small floods, which can be similar to those of infrequent extreme floods. Framing the Challenge of Urban Flooding in the United States contributes to existing knowledge by examining real-world examples in specific metropolitan areas. This report identifies commonalities and variances among the case study metropolitan areas in terms of causes, adverse impacts, unexpected problems in recovery, or effective mitigation strategies, as well as key themes of urban flooding. It also relates, as appropriate, causes and actions of urban flooding to existing federal resources or policies.
