What the levee authority really wants for Louisiana's coast: John M. Barry
~The Southeast Louisiana Flood Protection Authority East -- the levee board responsible for protecting metropolitan New Orleans east of the Mississippi River -- filed suit July 24 against Exxon Mobil, BP, Shell and 94 other oil, gas and pipeline companies for destroying the land and marsh buffer that once provided natural protection to New Orleans from hurricanes.
As most readers know, approximately 1,900 square miles of Louisiana's coastal lands have disappeared in the past 80 years. This land loss is continuing and, coupled with sea level rise, if nothing is done most of Louisiana's coast will simply disappear. This would be disastrous for the country and the state -- and particularly the defendants in the suit. Chris John, head of Louisiana Mid-Continent Oil and Gas Association, wrote in The Times-Picayune and NOLA.com last week that coastal lands "protect critical oil and gas infrastructure from storm surge," adding that "our viability depends on" the coastal buffer.

~Several factors have contributed to land loss, and the oil and gas industry is by no means responsible for all of it. But even the industry recognizes it is responsible for much of it. The industry has dredged 10,000 miles of canals and pipelines through the marsh, allowing saltwater intrusion, killing plants. Without their root structure holding the land together, it melted into the ocean. In addition, the extraction of an immense volume of oil and gas from beneath the surface has caused the surface of the land to sink. Scientific studies, which included industry representatives, concluded that the industry caused an estimated 36 percent of the land loss statewide. And Chris John conceded, "Industry recognizes its role" in the loss.
By destroying the land buffer that once protected populated areas, the industry has made the levee board's task far more difficult and far more expensive. Don't take our word for it. In 2006, when the state of Louisiana sued the federal government for revenue from off-shore production, Bob Bea, one of the most respected flood experts in the world and formerly Shell's chief off-shore engineer, stated that the industry "contributed significantly to the loss of natural defenses such as barrier beaches, wetlands, and marshes. In several important cases, it was the loss of these natural defenses that contributed to the unanticipated breaches of flood protection facilities that protected the greater New Orleans area during Hurricane Katrina and led to the repeated flooding during Hurricane Rita."
