These coordinates were used as control for the FLI-MAP survey performed in February 2017. Fugro utilized FM400-006 for data collection. The horizontal positions were computed in a least squares adjustment of the GPS data by holding to the published NAD83 (2011) positions of CORS: "MARY" and "MSIN". The vertical positions (ellipsoidal heights) were computed in a least squares adjustment of the GPS data by holding to the published NAD83 (2011) (EPOCH 2010.0) ellipsoidal height of CORS: "MSIN". The NAVD88 orthometric height (elevation) was computed by applying GEOID 09 to the computed ellipsoidal height of each station. The elevations listed above (in black) are published NAVD88 elevations.

The horizontal coordinates are valid at the epoch date displayed above which is a decimal equivalence of Year/Month/Day. ** This station is in an area of known vertical motion. Due to the variability of land subsidence, uplift, and crustal motion, NGS has, determined the orthometric heights for marks in these suspect subsidence areas should be considered valid only at the epoch date associated with the orthometric height. These heights must always be validated when used as control. All previously superseded orthometric heights are now considered suspect and are available in the superseded section. NGS does not recommend using suspect or superseded heights as control. The orthometric height was determined by GPS observations and a high-resolution geoid model using precise GPS observation and processing techniques. Significant digits in the geoid height do not necessarily reflect accuracy. GEOID12B height accuracy estimate available here.

    HURRICANES KATRINA AND RITA – LOUISIANA’S RESPONSE AND RECOVERY Ray A. Mumphrey, P.E., Louisiana Department of Transportation and Development, Baton Rouge, Louisiana, and Hossein Ghara, P.E., MBA, Louisiana Department of Transportation and Development, Baton Rouge, Louisiana KEYWORDS: Louisiana Department of Transportation and Development, National Oceanic and Atmospheric Administration, Federal Emergency Management Agency, Contra flow, Inundation, Fixed and Movable Bridges, Open Water Bridges, Coastal Protection and Restoration Authority ABSTRACT: Louisiana’s transportation and hurricane protection system took a tremendous blow from two major hurricanes that struck the coast of Louisiana in 2005, hurricanes Katrina and Rita. This presentation will introduce the audience to the transportation infrastructure damage Louisiana experienced as a result of these two storms and will describe how Louisiana is responding to the disasters and our road to recovery. Figure 1 - Hurricanes that hit the coast of Louisiana since 1900 As Louisiana residents, we become accustom to the ever present threat of hurricanes. Refer to figure 1. Much like other parts of the country, which have other natural disasters such as tornados, mud slides, avalanches or earthquakes, we just prepare for the worst, minimize loss of life and property, and thank God when it’s all over. As engineers we know we can always rebuild structures, and possibly restore livelihoods, but loss of life is not replaceable. 2005 STORMS Hurricane Katrina was a category 4 storm when it made landfall on August 29, 2005, along the Louisiana – Mississippi Gulf Coast. The storm was fast moving and provided minimum time for preparation. Refer to figure 2. “Hurricane Katrina was the most destructive hurricane to ever strike the U.S.” NOAA Just as we were getting back on our feet from the impacts of Hurricane Katrina, BAM! We were faced with another storm, Rita.
  • Fort Proctor: a Conditional Preservation

    Fort Proctor: a Conditional Preservation

    Fort Proctor: A Conditional Preservation Ursula Emery McClure, Bradley Cantrell Louisiana State University, Baton Rouge, LA ABSTRACT: The preservation and sustainability of building cultural heritage in indeterminate landscapes and sites at extreme environmental risk raises several questions regarding methodology. 1. What are the priorities for preservation of built works where degradation is accelerated by global environmental shifts? 2. What does one preserve of past cultures when the physical ground it once occupied is gone? 3. What are the methods for Historic Preservation when to preserve means much more than stabilizing a built project in time but also includes the preservation/sustenance of the land, the environment, and the cultural relevance? 4. If one cannot physically preserve does that mean its presence and cultural significance is nullified? To investigate these questions, the research team selected Fort Proctor, a NHRP site at extreme environmental risk. Fort Proctor is one of several forts built along Lake Borgne in Southeastern Louisiana following the War of 1812. Since then, Fort Proctor has remained in a fluctuating landscape as a static marker or datum, recording major ecological changes within the dynamic coastal environment. To understand the structure’s deconstruction and degradation as well as the changing Gulf of Mexico ecologies, a rich historical context was assembled from a complex array of disparate datasets (physical site and geographical condition surveys, material analyses, photogrammetric and photographic documentation, and GIS mapping.) From the data, the researchers developed time-based animations that explore the test site in four time-scales; one day, one year, 200 years, and geologic time. The animations present perspectival visualizations that illustrate the aesthetic and atmospheric qualities for each scale while overlaying analytical data and historical facts.

Project Location: Region 2, Pontchatrain Basin, Orleans Parish, South of I-10, on Bayou Sauvage NWR, with borrow area in Lake Pontchartrain. Problem: The landfall of Hurricane Katrina in southeast Louisiana destroyed thousands of acres of marsh and other coastal habitats in the Lake Pontchartrain basin. The hurricane weakened the Lake Pontchartrain shore between the lake rim and interior marshes near Bayou Chevee. In some cases the storm removed large expanses of the shoreline and exposed interior marshes. Currently only a portion of the lakeshore is protected by a rock dike (PPL 5, PO-22). This dike was originally tied to the shoreline; however the interior marsh has eroded away. Continued shoreline erosion and future storms could create a direct path of open water connecting Lake Pontchatrain with Irish Bayou and the Bayou Sauvage NWR. Goals: Create 135 acres of marsh and provide shoreline protection to about 26,876 feet of the Bayou Sauvage NWR. The project would maintain the shoreline integrity of Lake Pontchartrain and reduce the threat of Lake Pontchartrain merging with Irish Bayou and the Bayou Sauvage Refuge. The project would also help to buffer and protect the stability of the existing federal hurricane protection levee in New Orleans East.

    Artist George L. Viavant and the Old Gentilly Road

    NEW ORLEANS NOSTALGIA Remembering New Orleans History, Culture and Traditions By Ned Hémard Artist George L. Viavant and The Old Gentilly Road Naturalist and painter of Louisiana wildlife and marshland scenes George Louis Viavant (August 6, 1871 – November 30, 1925) sat in his buggy alongside the two old Michoud sugarhouse chimneys on Old Gentilly Road, once an early Indian trail, to pose for the photograph below. The land around him was primarily hunting grounds. Artist George Viavant on the Old Gentilly Road On January 15, 1939, an article in the Times-Picayune entitled “Chimneys Remain as Trail Becomes 4-Lane Highway,” reported the history of the old Indian trail and its upgrade to a modern paved thoroughfare. “Two sugarhouse chimneys stand as monuments” along Gentilly Road, along which stands the ancestral home of the Viavant family. The article began with comments by Louise Viavant, sister of artist George, whose grandfather Judge Augustin Viavant was the first of the Viavant family to live on what was known for many years as the Viavant Plantation, toward the Chef Menteur from New Orleans. Louise and George’s father, Henry Viavant, built a hunting lodge on the property about 50 years before. It was at this very same lodge that actress Sarah Bernhardt stopped on her way to capturing her first alligator in 1901. Back then the land was “swampy and wild life was abundant.” The lodge was eventually converted to the family home. Miss Viavant explained, “In the first part of the last century,” (that’s the early 1800s), “Gentilly Road was still an Indian trail which followed the curves and angles of Bayou Sauvage and connected the city with the Chef Menteur.” Today the area is known as the Michoud section, but in the article it was spelled in the old manner, “Micheaud.” She spoke of the area’s “forests of oaks and cypress trees, lagoons and bayous, and wild life even to bears, according to legend.

  • A Medley of Cultures: Louisiana History at the Cabildo

    A Medley of Cultures: Louisiana History at the Cabildo

    A Medley of Cultures: Louisiana History at the Cabildo Chapter 1 Introduction This book is the result of research conducted for an exhibition on Louisiana history prepared by the Louisiana State Museum and presented within the walls of the historic Spanish Cabildo, constructed in the 1790s. All the words written for the exhibition script would not fit on those walls, however, so these pages augment that text. The exhibition presents a chronological and thematic view of Louisiana history from early contact between American Indians and Europeans through the era of Reconstruction. One of the main themes is the long history of ethnic and racial diversity that shaped Louisiana. Thus, the exhibition—and this book—are heavily social and economic, rather than political, in their subject matter. They incorporate the findings of the "new" social history to examine the everyday lives of "common folk" rather than concentrate solely upon the historical markers of "great white men." In this work I chose a topical, rather than a chronological, approach to Louisiana's history. Each chapter focuses on a particular subject such as recreation and leisure, disease and death, ethnicity and race, or education. In addition, individual chapters look at three major events in Louisiana history: the Battle of New Orleans, the Civil War, and Reconstruction. Organization by topic allows the reader to peruse the entire work or look in depth only at subjects of special interest. For readers interested in learning even more about a particular topic, a list of additional readings follows each chapter. Before we journey into the social and economic past of Louisiana, let us look briefly at the state's political history.

    Decision-Making Chronology for the Lake Pontchartrain & Vicinity

    DECISION-MAKING CHRONOLOGY FOR THE LAKE PONTCHARTRAIN & VICINITY HURRICANE PROTECTION PROJECT FINAL REPORT FOR THE HEADQUARTERS, U.S. ARMY CORPS OF ENGINEERS SUBMITTED TO THE INSTITUTE FOR WATER RESOURCES OF THE U.S. ARMY CORPS OF ENGINEERS Douglas Woolley Leonard Shabman March 2008 ii Forward The one-two punch of Hurricanes Katrina and Rita in August and September of 2005 proved calamitous to a vast swath of the U.S. Gulf Coast across the States of Louisiana, Mississippi, Alabama, Florida, and Texas. While still offshore in the Gulf of Mexico, Hurricane Katrina’s 175 mph winds created the highest storm surge yet recorded at landfall in North America. Katrina’s storm surge overwhelmed many of the levees and floodwalls for greater New Orleans designed and constructed by the U.S. Army Corps of Engineers, collectively known as the Lake Pontchartrain & Vicinity Hurricane Protection Project (LP&VHPP). The result was a human tragedy—more than 1,600 people killed or missing and presumed dead, with over 1,250 confirmed deaths in Louisiana alone. In economic terms, the flooding from Katrina represents the costliest natural disaster in U.S. history. Direct flood damages to residential, non-residential, and public properties and infrastructure in greater New Orleans approached $28 billion, with further indirect economic effects and long- lasting socio-economic disruption to the region. In the immediate aftermath of the tragedy, the Secretary of Defense directed that that Army enlist the National Academy of Sciences to conduct a thorough review of the engineering aspects of the performance of the levees and floodwalls in place in New Orleans on August 29, 2005.
