Project Map

Levee and development in floodplain, Alton, IL

Location and Description:  The study area is comprised of the large river floodplains within the greater Metropolitan St. Louis area and includes the City of St. Louis plus four Missouri Counties of Franklin, St. Charles, St. Louis, and Jefferson and five Illinois Counties of Calhoun, Jersey, Madison, St. Clair, and Monroe. Approximately 800,000 people are estimated to live in, work in or transit these floodplains. This study will examine the cumulative effects of various types of past development such as levees, flood control reservoirs, river navigation structures, transportation and other infrastructure as well as project the induced flooding effects associated with various types of potential future development. The impacts will broadly address impacts to wetlands, navigation, and commercial floodplain activities. These findings could be invaluable to local and regional decision makers as well as to the Corps of Engineers and other Federal planners, such as the Federal Emergency Management Agency, in making decisions on the full costs, benefits, and impacts associated with various federal, state, and local projects.
