|The purpose of the proposed action is to construct a more effective Hurricane Storm Damage Risk Reduction System (HSDRRS) for eastern parts of St. John the Baptist and St. Charles Parishes, Louisiana. Further engineering design and investigations of the 2016 WSLP EIS levee alignment indicate that sections of the levee need to be widen and shifted. Additionally, it is likely that the Bonnet Carre’ Spillway (BCS) does not have enough suitable clay borrow material to construct the levee. The use of the five stockpile and staging areas described in SEA 570 as borrow sources and the use of licensed commercial borrow sources would provide enough additional borrow for construction. There are other feature and plan changes being considered that are described in Section 2.2. The location of the proposed action is in St. John the Baptist and St. Charles Parishes, near the communities of Montz in St. Charles Parish, and Laplace, Reserve, and Grayville in St. John the Baptist Parish, Louisiana.
