Resource Challenge

Much of Louisiana's coastal land loss is due to both natural and human-induced causes.  The cumulative effect of human activities and natural processes in the coastal area has drastically altered the natural balance from net land-building deltaic processes to land loss due to a combination of altered hydrology, subsidence, and erosion.

  • Nearly 90 percent of all coastal land loss in the lower 48 states today is occurring within Louisiana
  • As a result of human activities and natural coastal processes, coastal Louisiana has lost more than 1.22 million acres of coastal wetlands within the last 70 years
  • As recently as the 1970s, the loss rate for Louisiana’s coastal wetlands was as high as 25,600 acres per year (or about 40.0 square miles per year)
  • The current net rate of land loss (between years 1978-2000) was about 19,136 acres per year (or about 29.9 square miles per year)

  • Between 328,000 and 431,000 acres will vanish in the next 50 years

  • The 120-year (1930-2050) loss totals 1,668,000 acres or 34 percent of Louisiana's historic coastal wetlands  

  • The coastal wetlands, built by the deltaic processes of the Mississippi River, contain an extraordinary diversity of habitats that range from narrow natural levee and beach ridges to expanses of forested swamps and freshwater, brackish and saltwater marshes.  These habitats are one of the nation’s most productive and important natural assets.

    •  Louisiana’s coast is at the end of the North American Central and Mississippi flyways where nearly 70 percent of the ducks migrating along these flyways winter 
    •  Coastal Louisiana also provides critical stopover habitat for neotropical migratory songbirds, as well as critical habitat for many species of water birds and threatened and endangered species such as the endangered brown pelican, piping plover, and sea turtles

    • Louisiana produced about $300 million of commercial marine fish landings, including shrimp, crabs, menhaden and other commercial finfish in 2000 

    •  Recent data from the U.S. Fish and Wildlife Service (USFWS) show expenditures on recreational fishing in Louisiana to be nearly $897 million annually   

    • Coastal Louisiana is home to more than two million people, representing 46 percent of the state’s population.  When investments in facilities, supporting service activities, and the urban infrastructure are totaled, the capital investment in the Louisiana coastal area adds up to more than $100 billion.  These economic and habitat values, which depend on the biological productivity of Louisiana’s coastal wetlands, merit national attention.  For example, more than 30 percent of the nation’s seafood comes from offshore Louisiana.  In addition to providing vital habitat to commercial and recreational wildlife and fishery resources, the coastal wetlands protect an internationally significant commercial-industrial complex from the destructive forces of storm-driven waves and tides. 

      This complex includes deep-draft ports that handle 16 percent of the Nation’s waterborne commerce by tonnage and the most active segment of the Nation’s Intracoastal Waterway.  In 2000, Louisiana produced 104 million barrels of oil and condensate valued at $3.1 billion and about $5.6 billion worth of natural gas.  Louisiana currently provides more than 28 percent of the total crude oil and more than 26 percent of the total natural gas produced in the United States. 

      The continued loss of Louisiana’s coastal wetlands places the following wetland functions and values at risk:

      • commercial harvest of fishery resources of national importance
      • oil and natural gas production  
      • petrochemical industries  
      • recreational saltwater and freshwater fisheries
      • North American Central Flyway waterfowl wintering habitat  
      • resting and refueling areas for neotropical migrants  
      • ecotourism, and  
      • habitats for nationally endangered and threatened species

Examples of Key Partners

To help sustain the coastal erosion problem in Louisiana, in March 2002, the U.S. Army Corps of Engineers, New Orleans District, and the Louisiana Department of Natural Resources (LADNR) jointly decided to undertake development of an ecosystem restoration plan.  Other federal agencies who contributed to the plan’s success included:  Environmental Protection Agency (EPA), National Oceanic Atmospheric Administration (NOAA), and the Natural Resources Conservation Service (NRCS) and the Department of Interior (DOI) which includes the U.S. Fish and Wildlife Service (F&WS), the United States Geological Survey (USGS) and the Minerals Management Service (MMS).   In addition, academia, businesses, environmentalists, non-profit agencies, various stakeholder groups and interested citizens have provided their voice and expertise to restoration goals and strategies. 

Results and Accomplishments

Typically, Corps of Engineers studies include an interdisciplinary approach in its feasibility reports and National Environmental Policy Act (NEPA) documents (e.g., Environmental Impact Statements [EIS]) that may include portions prepared by contractors and other experts for very specific aspects of a particular study.  The Corps also typically includes the U.S. Fish and Wildlife Service's Coordination Act Report as an appendix to the main report and EIS. 

In contrast, the nationally-significant catastrophic disaster of natural and human-induced coastal land loss in coastal Louisiana has engendered a heretofore unprecedented interagency cooperation and coordination extending from the working level to the highest administrative levels of Federal and state natural resources agencies to develop an ecosystem restoration plan for coastal Louisiana. 

The study’s approach was formulated and prepared by local academia, biologists, scientists, engineers, and other experts who contributed their knowledge and expertise into the report.  This Project Delivery Team (PDT) provided a truly unique and positive manner in advancing the state of the art in water resource planning.   

To further streamline the study’s progress, the PDT took a bold step with the formation of an on-site collocated team consisting of the other Federal and state natural resource agencies tasked with the day-to-day coordination and preparation, at the working level, of the LCA Study Report and Programmatic Environmental Impact Statement (PEIS).  Collocating or physically moving core team members into the same physical site improved informal multidisciplinary communication and cooperation among the team members, minimized response time to problems, and promoted closer working relationships and mutual trust within the PDT.  The collocation effort promoted and fostered “team synergy” and it quickly became obvious that the whole team was greater than the sum of its parts.  In addition to the local sponsor, the Louisiana Department of Natural Resources, other federal agencies who contributed to the report’s success included:  Environmental Protection Agency (EPA), National Oceanic Atmospheric Administration (NOAA), and the Natural Resources Conservation Service (NRCS) and the Department of Interior (DOI) which includes the U.S. Fish and Wildlife Service (F&WS), the United States Geological Survey (USGS) and the Minerals Management Service (MMS).   Collocating the cross-functional project-based team was instrumental in the ultimate success of the study. 

Responsibility for the LCA Study and compliance with the National Environmental Protection Act of 1969 (NEPA) process rests with the U.S. Army Corps of Engineers (USACE) in coordination with the local sponsor and other resource agencies.  However, all of the PDT members played a critical role in the LCA Study process by utilizing their subject matter expertise in the preparation of the PEIS and the Main Report.   

The LCA Study team composed the report using two primary objectives.  First, identify the most critical ecological needs of the coastal area and identify and evaluate the cost effectiveness of the projects that best meet those needs.  Second, it addressed the key long-term scientific uncertainties and engineering challenges facing the effort to protect and restore the ecosystem.  The plan also included an evaluation of the priority and implementation sequence for projects, including completing and modifying existing projects.  If Congress grants authorization of the LCA Study, the near-term program will provide funds for the next ten years for an estimated total cost of $2 billion dollars with a project lifespan of 50 years.  

Since the beginning of the study, each PDT expert directly participated in information and data gathering and analysis, formulating plans, analyzing alternatives, and assessing potential impacts to the significant resources.  The results of those efforts by the PDT were documented in the PEIS and the Main Report for historic conditions, existing conditions, and future without project conditions.  Once the plan alternative was selected and recommended, the future conditions of that plan were then analyzed and documented. 

The team, at any given time, averaged 40 personnel—with representatives from the Louisiana Department of Natural Resources and six other federal agencies.  Within the collocated team, there were several smaller teams that focused on more specific aspects of the study.  Benefits and successes of the team included:  facilitation of EPA participation in the review of the preliminary draft EIS for the marsh creation component of the Barataria Basin feasibility study; coordination with regulatory and planning staff; Grand Isle development issues; the proposed Port Fourchon maritime ridge project; EPA’s proposed Maurepas Swamp Diversion; coordination with the Corps CWPPRA (Coastal Wetlands Planning, Protection and Restoration Act) staff on freshwater diversions and other issues; and an increase in opportunities for regulatory site visits, while improving coordination on both specific permit issues and mitigation banking efforts. 

Some types of alternatives the study team members produced included, but were not limited to, structural and non-structural solutions that assured vertical accumulation to achieve sustainability of ecosystems; maintained estuarine gradients to achieve coastal habitat diversity; and maintained exchange and interface to achieve ecosystem linkages. These can be accomplished through implementation of the following project types: freshwater diversions, sediment diversions, outfall management, hydrologic restoration, marsh management, shoreline protection, barrier islands, dredged material/marsh restoration, sediment and nutrient trapping, and vegetation planting.

Specific significant resources/subject matter areas addressed by PDT members included:  EPA—gulf hypoxia and aspects of regulatory permits input; NRCS—soils, vegetation, and habitat resources; NOAA Fisheries—aquatic resources such as shell reefs, fisheries, shellfish, invertebrates, essential fish habitat, and threatened and endangered species; USFWS—wildlife resources, amphibians, reptiles, birds, mammals, and threatened and endangered species; LDNR—as the local cost sharing sponsor, provided support for project management, contract management, engineering, real estate (including access and indemnification for state-owned lands), and report preparation; USGS—geospatial coordination, geographical information systems/remote sensoring (GIS/RS) support, management of web site, data, and map production, digital library support, ecological support, and water quality resources.  In addition to the PDT members’ support, the academic community provided support and input for hydrologic and habitat modeling and benefit modeling.  The USACE provided expertise on planning and project/study management, plan formulation and alternatives analysis, budget, engineering and design, hydraulic, GIS, economic, real estate, historic and cultural resources, recreation, aesthetics, air quality, noise, hazardous, toxic, and radioactive wastes, water quality, significant environmental resources, expertise on NEPA compliance documentation as well as preparation of required permits and coordination with permitting agencies; and overall report preparation. 

 

 

Given the number of agencies and individuals involved in the LCA Study, a well-defined management structure, conducive to vertical awareness at every level, was considered necessary.  The various teams fell into one of three categories: coordination teams, project execution teams, and special teams.  Team representation was a natural progression of public outreach, with members interacting and engaging the public and stakeholders throughout the study.  

A large segment of the public affected by the loss of the state’s coastal wetlands is made up by more than two million residents who make Louisiana’s coastal zone their home.  It is also home to a unique cultural heritage that contains more than two million residents.  Tourists travel from all over the world to experience Mardi Gras, Louisiana style, the French Quarter, the Cajun culture, the heritage of Mark Twain’s Mississippi River, the birthplace of jazz, delta blues, Tabasco sauce, Oysters Rockefeller and blackened redfish. 

Due to the passionate interest in the restoration of Louisiana’s coastal wetlands and a strong commitment to ensure that Louisiana and the nation were aware of the study, the Corps and state hosted 43 public meetings throughout Louisiana, in Texas, Mississippi and Tennessee.  These meetings were held to inform the public about the study and to generate public interest and provide an avenue to input on key issues or concerns.  The Corps received hundreds of comments as a result, and several changes were made to the draft report.  For example, study managers reevaluated an earlier strategy of placing rock along the north channel of the Mississippi River Gulf Outlet to stem erosion and decided instead to take a more holistic approach of environmental restoration along a larger portion of the channel. 

The Louisiana coastal ecosystem is disappearing at an alarming rate, yet scientists believe that a self-sustaining ecosystem can be restored and maintained to protect the facilities, environment, and culture needed to support a growing economy.  Coastal restoration is not only for the future of Louisiana but also the future of the nation.  The level of interest and support for coastal restoration shown at the public meetings demonstrates that the citizens of Louisiana are ready for action. 

Processes to most planning phases within any Corps project are normally accomplished within a three to five year time frame, especially a study effort the size and scale of the LCA Study.  The study team undertook and successfully completed a complex effort involving multi-agency coordination, data management and application, within a time-constrained period.  The synergy created and fostered by all team members that were faced with an accelerated 18-month schedule and rigid milestones was able to meet all due dates that produced four draft reports, with each one assigned to a specific deadline.  It is essential to recognize that the collocation approach and its associated benefits will set new standards for planning future ecosystem restoration programs.

The LCA Study Team’s vital contributions, in the form of the LCA Study, should serve as the catalyst for sustaining an enormously productive ecosystem so important to the economy and well being of the State and Nation.

Innovation/Highlight

There were two distinct highlights for the LCA Plan. The collaboration among the many groups to undertake the development of an ecosystem restoration plan was a hands-on working relationship. The key participants included government, academia, businesses, environmentalists, non-profit agencies, various stakeholder groups and interested citizens that provided their voice and expertise to restoration goals and strategies. Another highlight was the use of hydrogeomorphic objectives in the study. These objectives emphasized establishing dynamic salinity gradients, increasing sediment input and maintaining or establishing natural landscape features and hydrologic processes.
