Flood Control, MR&T East Bank Mississippi River Levees

This work is an implementation of the work recommended as part of the Flood Control Mississippi River and Tributaries Project and is part of the effort to restore current authorized flood protection levels for the Mississippi River Levee Project.

Mendrop Engineering Resources was responsible for the preparation of a soils report; topographic field surveys and mapping of borrow areas, and the design and preparation of plans and specifications for the enlargement of approximately 2.7 miles of existing levee, including seepage and stability berms as necessary between stations 8305+00 and 8450+00 of the East Bank Mississippi River Levee. The use of borrow areas of a size and quantity necessary to provide the quantity of suitable material required for construction of the project were also included in the designed. Existing MS Hwy 475 is located along the crown of the levee. As part of the scope of work, a traffic control plan was developed to maintain traffic while the roadway was demolished and reconstructed as part of the levee enlargement.

Analyses and recommendations included in the Soils Report were based on a combination of data furnished by the Government and data generated during the geotechnical investigation. The Government furnished data consisted of soil borings, laboratory tests and Cone Penetration tests. Additional data collected during the geotechnical investigation included thirteen foundation borings; fifty-three seepage borings and sixty-seven borrow borings.

In addition, Mendrop prepared and maintained an effective quality control plan that assured that all professional services, designs, and construction drawings were performed and provided in a manner that met professional engineering quality and USACE standards.
