Louisiana State Penitentiary Levee, Mississippi River. Main Report and Final Environmental Impact Statement and Appendixes.
Abstract
The purpose and primary objective of this study is to review the report on the Mississippi River and Tributaries project, and other pertinent reports, with a view to determining whether incorporating the local levee at the Louisiana State Penitentiary into the Federal levee system is advisable. Investigations during this study identified and analyzed, in addition to the alternative of 'no-action,' both nonstructural and structural alternatives for providing increased flood protection. They showed that feasible nonstructural measures were already part of the without-project condition and that only one of the preliminary structural alternatives (plan A) was economically justified. Plan A provides for raising and strengthening the existing mainline levee to provide protection from the Project Design Flood. This plan was carried into the detailed study stage. In the detailed study process, plan A was reanalyzed to determine if its potential adverse environmental impacts could be further minimized. A modified plan, plan A1, was developed. This plan is identical to plan A except that construction methods would be modified to avoid valuable wildlife habitat in locating new borrow pits. Plan A1 was designated as the least environmentally damaging plan in the detailed study process.
