Abstract: The U.S. Army Corps of Engineers, Mississippi Valley Division, Regional Planning and Environmental Division South, has prepared this Environmental Assessment for the New Orleans District to evaluate the potential impacts of repairing and reinforcing a washout area on the east bank of the Mississippi River near Duncan Point in East Baton Rouge Parish, Louisiana. In mid-2015, after a prolonged high water period on the Mississippi River, flood waters on the river began to rapidly recede during August. Over a six day period, approximately 45 million gallons of water drained through a relatively small area of river bank on the east bank of the Mississippi River near Duncan Point. This rapid drawdown washed out a large quantity of sandy material on the east bank of the river creating two deep cuts in the river bank. Of the two cuts, the northern-most cut is approximately 12-feet deep, in relation to the adjacent land, and the southern-most cut is approximately 20-feet deep. The topography and hydrology of the area is such that the washout area is the single point of confluence of receding flood waters from a 45-acre borrow pit/sand pit operation located just downstream from the washout area. This Environmental Assessment has been prepared in accordance with the National Environmental Policy Act of 1969 and the Council on Environmental Quality’s Regulations, as reflected in the USACE Engineering Regulation ER 200-2-2. This Environmental Assessment provides sufficient information on the potential adverse and beneficial environmental effects to allow the District Commander, New Orleans District, to make an informed decision on the appropriateness of an Environmental Impact Statement or a Finding of No Significant Impact.
