Program Overview
Borrow Material for Levees
The U.S. Army Corps of Engineers, New Orleans District is in the midst of an unprecedented search for clay material to rebuild and reinforce the Greater New Orleans Hurricane and Storm Damage Risk Reduction System (HSDRRS) in southeast Louisiana. The total borrow requirement to complete the construction of HSDRRS hurricane protection levees and floodwalls is 93 Million CY. This Web site was created to serve as a reference for all landowners interested in providing clay material for these projects.
Clay Specifications
The earthen clay material shall be naturally occurring or Contractor blended. Addition of lime, cement, or other soil amendments for any reason is not permitted. Soil that is classified in accordance with ASTM D2487 and the Unified Soil Classification System as CH and CL is suitable. Soil classified as ML shall be considered unsuitable; however, minor amounts of ML may be suitably blended with CH or CL to formulate a material that classifies as a CL as per ASTM D2487. Soil must be free from masses of organic matter, sticks, branches, roots, and other debris, including hazardous and regulated solid wastes. Soil from a Contractor-supplied earthen clay material source may not contain excessive amounts of wood, however isolated pieces of wood will not be considered objectionable in the embankment provided their length does not exceed 1 foot, their cross-sectional area is less than four (4) square inches, and they are distributed throughout the fill. Not more than 1% (by volume) of objectionable material shall be contained in clay material ordered by the Government. Pockets and/or zones of wood shall not be acceptable. Material consisting of greater than 35% sands (by dry weight) or materials with a Plasticity Index (PI) of less than 10 will not be accepted as well as material having an organic content exceeding 9% by weight. Under no circumstances shall frozen earth, snow, or ice in the material be considered acceptable.
Status of Borrow Investigations
Total Available Borrow for HSDRRS is approximately 229 M cy
Remaining System Borrow requirement for contracts to be awarded is approximately 53 M cy
