Louisiana Coastal Wetlands Lawyer & Attorney : Erich P. Rapp : Kean Miller Law Firm : Serving New Orleans, Baton Rouge, Shreveport, Louisiana

Mark Schleifstein of the New Orleans Times-Picayune writing on June 19, 2008 in an article entitled, Levee authority backs national '8/29 Commission' investigation reported that the Southeast Louisiana Flood Protection Authority had passed a resolution asking Congress to create a 8/29 Commission to investigate the government's handling of the aftermath of Hurricane Katrina. The resolution was proposed by John Barry, the author of Rising Tide.

Barry stated,

"I'm really asking that they take a comprehensive look at the entire Mississippi River system, the entire Mississippi valley, from New York state to Idaho," Barry said. "They should look, for instance, at the dams on the upper Missouri River in detail, because they have a real impact on the amount of sediment that's carried in the river, which has a real impact on the erosion of wetlands in Louisiana."

"If the nation understood the reality of the negative impacts on us in the metropolitan area of economic decisions upstream that were made in the national interest," it might lead to better decisions in flood control involving both protection from hurricanes and high rivers."

John Barry has said it exactly right. I am not aware of anyone speaking more closely to my own thinking on the causes and solutions related to the loss of Louisiana's coastal wetlands than John Barry. The idea of a 8/29 Commission is an excellent one. The scope he suggests addresses exactly the issues that I have been raising in this blog. The loss of coastal wetlands in Louisiana is a national problem caused by the management of the Mississippi River drainage basin by the federal government. 

I am not suggesting the federal government should not manage the Mississippi River drainage basin. I am just urging the federal government to acknowledge and take responsibility for their predominant role in causing coastal land loss in Louisiana.

The National Academies Press has published its First Report from the NRC Committee on the Review of the Louisiana Coastal Protection and Restoration Program. The NRC is the National Research Council which group acts as the official scientific adviser to the federal government. 

The report is available for free download as a .pdf file from the National Academies web site. This is an important report worth reading. This report is a response to the Corps' March 2008 report entitled, "Louisiana Coastal Protection and Restoration Technical Report." In turn, the Corps' report was a response to a request from Congress for a category 5 hurricane protection plan for South Louisiana.

The Corps' report commendably speaks to the need to preserve and restore Louisiana's coastal wetlands in order to provide hurricane protection for the region. Nevertheless, one of the NRC committee's leading complaints about the Corps' plan is that it relies upon "sustaining the existing landscape" and yet the Corps has provided no evidence that it is possible to sustain the existing landscape. In this regard, the NRC committee complains that the Corps has not done the basic analysis of sediment available in the Mississippi River for a determination of what portion of the coastal wetlands in Louisiana can be sustained. If insufficient sediment exists in the Mississippi River water flow to sustain the existing coastal environment then the Corps' entire report is ill conceived.

If the sediment budget in the river is insufficient to sustain the existing coastal environment, the Corps and others will have to make some difficult decisions about what parts of the coastal landscape can be saved and what will not be saved. The Corps has not addressed this issue.

This missing analysis takes us to the core of the problem that I have written about in this blog since its outset. The most fundamental cause of coastal wetland loss in Louisiana, particularly south of New Orleans where below a certain point there are no levees, is lack of sediment in the Mississippi River water flow as the result of dams and reservoirs as well as locks and slack water pools in the northern parts of the Mississippi River drainage basin. These river structures reduce the sediment load in the river.

A reduced sediment load in the river is good for navigation and bad for coastal wetland building. The Corps must deal with a conflict between those competing interests. The Corps operating north of Louisiana wants a river with a reduced sediment load because that river condition makes it easier to maintain a navigation channel of a set depth. Less sediment in the river flow means less dredging of the navigation channel for the Corps.

The Corps in Louisiana has the same concern with navigation, but also has a need for sediment load for use in coastal wetland restoration and preservation. Those interests compete with one another to some extent. Unfortunately, coastal wetland protection and restoration in Louisiana does not get much, if any, consideration when the Corps makes a decision north of Louisiana adversely impacting on sediment load in the Mississippi River that will ultimately reach Louisiana. The interests of navigation prevail in such considerations north of Louisiana and most of those considerations within Louisiana.

The Corps needs to make a careful examination of the Mississippi River sediment load as it relates to proposed coastal wetland restoration and preservation projects. The Corps also needs to begin considering sediment load as it relates to Louisiana's coastal restoration and protection needs when it makes decisions along the entire course of the Mississippi River drainage system. Until this analysis is done and this consideration is given, no one will know what can really be done to preserve and restore Louisiana's coastal wetlands.

The current approach is to view coastal wetland preservation and restoration in Louisiana as a matter of regional decision making in relation to management of the Mississippi River in Louisiana. In reality, In reality, the preservation and restoration of Louisiana's coastal wetlands requires considered decision making across the entire Mississippi River drainage basin covering much of the continental United States.

As I have written many times before, the principal cause of coastal wetland loss is the reduction of sediment load in the Mississippi River. The reduction in sediment load has been caused primarily by the construction of locks and dams in the Mississippi River drainage basin, and the dams in the Missouri and Arkansas River systems are the most significant.

For the Corps of Engineers representatives working north of Louisiana, the reduction in the sediment load is a good thing. If your primary concern is navigation in the river system, a river with little sediment load is a good river. It means the Corps does not have to dredge the river bed as much.

In contrast for the Corps of Engineers in New Orleans tasked with coastal wetland restoration, a river with a limited sediment load makes their restoration job harder. Of course, the Corps in New Orleans is also given the task of maintaining navigation on the Southern course of the river. Thus, the Corps in New Orleans also prefers the smallest possible sediment load for management of their navigation responsibilities.

Which objective does the Corps serve? How do they decide which objective to serve and when? As far as I can determine, the Corps gives no consideration to the sediment load in the Mississippi River system needed for restoration and preservation of Louisiana's coastal wetlands when the Corps makes decisions about river management north of Louisiana. As a practical matter, the Corps cannot serve both objectives with no oversight and be expected to preserve and restore Louisiana's coast. The navigation interest extends for most of the river system course and the focus on preservation and restoration of coastal wetlands is an active part of decision making only in the Southernmost section of the river. Preservation and restoration of coastal wetlands loses and navigation wins in that internal competition at the Corps. As a practical matter, it cannot be any other way. 

The responsibilities for decision making need to be split and a neutral third party needs to be responsible for balancing the two interests.

A good recent news article expressing concern with the negative impact of sediment load on navigation can be found in the Baton Rouge Advocate on April 12, 2008. The article was written by John A Colvin and is entitled, Mississippi River sediment piling up.

The Baton Rouge Advocate published a letter on March 5, 2008 under the headline, Letter: Wetlands require urgent action. Kerry St. Pe, the program director for the Barataria-Terrebonne National Estuary Program, wrote in the Baton Rouge paper that all stakeholders must join together to move quickly to restore coastal Louisiana.

St. Pe concludes that the state cannot afford delays that might be caused by strategies that could result in drawn-out disagreement. He emphasizes the adoption of proven technology on a large scale. In particularly, he suggests using existing sediment delivery technology such as dredges, pumps and pipelines need to be employed immediately. The land built through the sediment delivery processes must then be supported with small to medium size river diversions. These diversion will sustain the new land.  

St. Pe expresses concern about the disagreements arising from large scale river diversions. He views large scale diversions as potentially contentious and questions whether such diversion have long term benefits.

In sum, St. Pe thinks Louisiana should focus on the strategies where consensus exists.

When I have questions about basic geology, I refer to Physical Geology by Charles C. Plummer, David McGeary, and Diane H. Carlson. It is an introductory college text with great explanations for everything geology related with many pictures and diagrams. 

For example, why does flowing water transport or carry sediment? The answer is on page 28,

"In a water molecule, the two hydrogen atoms are tightly bonded to the oxygen atom. However, the shape of the molecule is asymmetrical, with the two hydrogen atoms on the same side of the atom. This means the atom is polarized, with a slight excessive positive charge at the hydrogen side of the molecule and a slight excessive negative charge at the opposite side. Because of the slight electrical attraction of water molecules, other substances are readily attached to the molecules and dissolved or carried away by water. Water has been called the universal solvent. Dirt washes out of clothing; water, in blood, carries nutrients to our muscles and transports waste to our kidneys and out of our bodies."

Of course for our purposes in this blog, streams and rivers also transport sediment.

The Mississippi River built the part of Louisiana now being lost to the sea. All water running across land carries sediment. All rivers and streams carry sediment. Rivers, streams and the sheet flow over the adjoining land are eroding sediment in one place and depositing it in another.  This natural process has existed as the earth has existed.

Transport of sediment in rivers is part of the hydrologic cycle. 

Water evaporates out of the ocean. The clouds moves over land, and the water returns to earth as rain. The rain runs across the land eroding sediment as it gathers in streams and rivers and makes its way back to the ocean. This description is a gross simplification, of course, because some of the water goes into storage as ground water, in lakes, plants and elsewhere along the way from falling as rain to its return to the ocean. 

As a result of the hydrologic cycle, water transporting sediment in the Mississippi River and depositing it at or near the coast built much of Louisiana over a very long period of time.

The law applies to this process. The transport of sediment in rivers is a natural process that creates a legal relationship between the land along the upstream portions of a river and the lands adjoining the same river system much closer to the ocean. If the process is disrupted, the land building and maintenance stops and as will be described later, the land slowly turns back to open sea.

This blog will show how the law protects property rights associated with the sediment transport process in rivers.
