Under existing conditions, levee conditions are greatly. variable. A typical present levee condition is a 20-foot-wide crest at an approximate elevation of. +8.5 feet above mean sea level with an exterior (water-side) slope of 2:1 (horizontal to vertical) and. aninterior (land-side) slope of 4:1. Under the proposedproject, a typicalimproved levee wouldhave.
The history of man's attempts to control the Mississippi is full of both success and failure. Levees already existed when the first French trappers ventured into the wilds of Louisiana. These levees were formed naturally by the Mississippi's fluvial processes and tended to be no more than a meter or two in height. Building up these natural levees was the first solution to the flooding problem. In 1717, the first manmade levee system was started by Bienville, the founder of the city of New Oreans. The construction of the first levees, which reached only three feet in height, was completed in 1727.
