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.
This process, repeated over and over, forms low ridges or mounds known as natural levees (pronounced LEH-veez). Levees built by humans along rivers in an effort to control flooding are known as artificial levees. Natural levees are composed primarily of gravel and sand. They are steep on the side facing the stream channel and gently sloping on the other side. Varying greatly in size, levees may be several feet in height and up to a mile or more in width.
