Inner Harbor Navigation Canal Corridor

NEW ORLEANS – The U.S. Army Corps of Engineers, New Orleans District Commander, Col. Edward Fleming, yesterday signed the Decision Record for restoring and reinforcing the levees and floodwalls along the Inner Harbor Navigation Canal. This work is necessary to meet the current Hurricane & Storm Damage Risk Reduction System design guidelines for seepage and stability criteria.

“Individual Environmental Report Supplemental (IERS) 11B Tier 2 Borgne,” is available online at:


Reinforcement methods along the Inner Harbor Navigation Canal corridor include the following:

· Deep Soil Mixing – for strengthening the canal levees;

· Relief Wells – for intercepting seepage;

· Stability Berms – for strengthening the canal levees;

· Buttress Walls – for strengthening the canal floodwalls;

· Concrete Slabs – for resisting deflection (bending) of canal floodwalls.

Contracts will be advertised early next year and construction will be complete by the beginning of the 2011 hurricane season. All reinforcement work will be conducted within the existing right of way.

Alternative arrangements allow the Corps to expedite the environmental process required of all federally-funded projects while fully complying with the intent of the National Environmental Policy Act. IER documents are available on www.nolaenvironmental.gov.
