NEW ORLEANS – The U.S. Army Corps of Engineers released an environmental document today that outlines the proposed action for the Caernarvon Floodwall and the requirements to meet the 100-year design elevations and design criteria for St. Bernard risk-reduction project.
“Draft Individual Environmental Report (IER) 9 Caernarvon Floodwall, St. Bernard Parish, Louisiana,” reviews the considered alternatives and evaluates the potential human and environmental impacts that construction of the proposed realignment of the Caernarvon Floodwall, to the west of the Caernarvon Canal, may have on the residents.
The new alignment will tie-in to the Mississippi River Levee system and include new floodgates across Highway 39 and Norfolk Southern Railroad. A 56-foot wide navigable structure across the Caernarvon Canal is also part of the proposed action.
The projects within IER 9 would reduce impacts from a storm surge event that has a one percent chance of occurring in any given year. This would reduce risk of damage to property and infrastructure to communities in St. Bernard.
Written or verbal comments on IER 9 must be submitted to the Corps by midnight on December 24, 2009. Comments received during the public review period will become part of the official record.
Questions or comments concerning Individual Environmental Reports or the Corps’ environmental process may be addressed to:
