Lower Mississippi River Plan and Profile Sheets
USACE New Orleans District
| The Mississippi River Plan and Profile Maps provide a plan view of levee/floodwall alignments together with their corresponding profile elevation plots. The plan view includes alignment classification, stationing, structures, floodgates, and levee crossings such as utilities and cattle guards. The profile view includes the best available existing elevation data, construction reaches, flow lines, and project grades relative to the alignment stationing. A Map series was created for each Louisiana levee district along the Mississippi River within the district boundary of the New Orleans District of the U.S. Army Corps of Engineers. Series are also included for Bonnet Carre upper and lower guide levees. Each series is divided into individual map pages scaled at 1 inch = 400 feet for ANSI D-sized prints, with approximately 10,000 feet of levee mapped on each page. Existing elevations were derived primarily from a high-precision survey job conducted in 2004, with updates within subsidence areas from a survey job conducted in 2009. Project grades and flow lines were taken from the published June 1978 report, "Flood Control, Mississippi River and Tributaries Project Refined 1973 MR&T Project Flood Flow Line", and converted from NGVD29 to NAVD88. Conversion of report stationing from "Second-Order Derived Baseline" to the "2004 Baseline" was included in the development of this product. The original published report contained several typographical errors in the tabular data. These errors were corrected in the development of this product. Maps reflect best available data as of their date stamps, which are located in the lower right hand corner above the inset maps. Intended use for this product is for reference and analytical purposes only.
