The Importance of Levees

While those levees don’t necessarily protect all the people living in the 881 counties that have them, a study for Levees.org by geographer Ezra Boyd concludes that the levees more than pay for themselves when their cost is compared to the investment they protect. Counties with levees account for only 28 percent of the nation’s counties and only 37 percent of the nation’s land area. But they contain 55 percent of the nation’s population, more than 156 million people, according to the study.
