FINDINGS OF FACT AND CONCLUSIONS OF LAW STANWOOD R. DUVAL, JR., District Judge. The Court conducted a 19-day bench trial of this tort suit brought by six plaintiffs seeking compensation from the United States based on their contention that as the result of certain defalcations of the U.S. Army Corps of Engineers (“Corps” or “Army Corps”) with respect to the maintenance and operation of the Mississippi River Gulf Outlet (“MRGO”), the United States is liable to them under the Federal Tort Claims Act (“FTCA”), 28 U.S.C. § 2671, et seq. for damages incurred in the aftermath of Hurricane Katrina. The Court exercised jurisdiction over the parties, and pursuant to 28 U.S.C. § 1331 and 28 U.S.C. § 1346(b) and 28 U.S.C. § 2671 (FTCA) has jurisdiction over this suit by plaintiffs against the United States for the damages alleged. After considering all testimony and evidence presented at trial and the deposition testimony that the Court reviewed prior to the trial, the Court is prepared to rule as follows. To the extent a finding of fact constitutes a conclusion of law, the Court adopts it as such. To the extent a conclusion of law constitutes a finding of fact, the Court adopts it as such. Prior to this trial over the course of two years, the Court decided a number of motions by which the United States sought the dismissal of this suit prior to trial. In In re Katrina Canal Breaches Consol. Litig. (Robinson), 471 F.Supp.2d 684 (E.D.La.2007) (Katrina I), the Court denied a Rule 12(b)(1) motion in which the Government contended, among other arguments, that the Court lacked jurisdiction over the subject matter of the case based on the Flood Control Act of 1928 (“FCA”), specifically, 33 U.S.C. § 702c, which provides that “[n]o liability of any kind shall attach to or rest upon the United States for any damage from or by floods or flood waters in any place.” 33 U.S.C. § 702c. This Court denied the motion and in particular refused to apply the United States’ overly broad interpretation of that statute and the seminal case of Central Green Co. v. United States, 531 U.S. 425, 121 S.Ct. 1005, 148 L.Ed.2d 919 (2001). Relying on Graci v. United States, 456 F.2d 20 (5th Cir.1971), this Court found that the Corps could be held liable for damages arising out of activities surrounding a navigational channel notwithstanding the fact that those actions caused the failure of certain levees. The Court wrote: ... [T]he Government’s position ignores the fact that even the Supreme Court in Central Green opened the possibility of a segregation of damages — those for which the Government would be immune under § 702c and those for which immunity would not attach. Indeed, the Government even concurred with this reading at oral argument. (See Transcript of Hearing, October 27, 2006, at 33). For example, would the United States be immune for all damages if a Navy vessel lost control and broke through a levee where the sole cause of the failure of that levee was the Navy vessel’s negligence? Thus contrary to the Government’s contention that Central Green broadens the immunity provided by § 702c, in realty Central Green requires the Court to identify the cause of the damage rather than base a decision on the mere fact that a flood control project was involved. Central Green does not answer the question of what nexus to a flood control project is required for floodwaters to trigger immunity. Id. at 695. Thus, the Court undertook this trial to determine, inter alia, whether the Corps’ activities with respect to the MRGO acted like that Navy vessel destroying the levee. 1. FINDINGS OF FACT A. FACTUAL BACKGROUND 1. Construction of MRGO In 1943, Congress requested a report from the Chief of Engineers, Secretary of the Army, on the viability of the Mississippi River-Gulf Outlet which report was authorized by the River and Harbor Act and was approved on March 2, 1945. DX-0573 (H.R. Doc. No. 82-245 (1951)) at 1. The genesis of this request was apparently two-fold. The activity experienced at the Port of New Orleans during World War II made clear that an expansion and dispersion of those facilities was necessary in case of future hostilities. Id. at 41, ¶¶ 75-76. In addition, a shorter route to New Orleans would provide savings to the maritime industry by decreasing the distance from the Gulf of Mexico to New Orleans by about sixty miles. Id. at 35-36, ¶¶ 56-57. Indeed, the needs of the maritime industry were a substantial focus for the Corps’ activities as concerned the MRGO. At the same time, however, the safety of the citizenry of the metropolitan New Orleans area was another of its charges as demonstrated by Congress’ authorization of the Lake Pontchartrain and Vicinity Hurricane Protection Plan. The tension as to which client’s needs were more important plays a decisive role in this tragedy. On September 25, 1951, a report dated May 5, 1948, from the Chief of Engineers, United States Army (“Chiefs Report’’) was transmitted to the House of Representatives. DX-0573 (H.R. Doc. No. 82-245 (1951)) (“Chiefs Report”). It recommended the construction of a deep-draft channel on the east side of the Mississippi River. The route ran from the Inner Harbor Navigational Canal (“IHNC”) eastward along the Gulf Intracoastal Waterway (“GIWW”) to a point near Michaud, this section being called Reach 1, before striking a southeasterly course to and along the south shore of Lake Borgne and through the marshes to and across Chandeleur Sound to the Gulf of Mexico. This section of the channel is referred to as Reach 2. As Reach 2 moved southward, it cut through Bayou Bienvenue at the channel’s more northerly end and Bayou La Loutre at its more southerly end. The channel was to be 36 feet deep and 500 feet wide, increasing at the Gulf of Mexico to 38 feet deep and 600 feet wide. Id. at 2. Its construction was to be done “generally in accordance with the plans of the division engineer and with such modifications thereof as in the discretion of the Secretary of the Army and the Chief of Engineers may be desirable.” Id. at 5, ¶ 3. In making the decision to place the MRGO at this location, the Corps stated as follows: Proponents of additional deep-draft outlets have assumed that such channels can be secured and maintained by dredging, but departmental experience in maintenance and improvement of Gulf-coast entrance channels does not support such assumption where shallow exposed coastal lakes or sounds are encountered. It has been demonstrated repeatedly that such channels should be sited through land cuts or provided with effective barriers to preclude return of dredge spoil into dredge channels. Hence the plan of improvement presented herein for an east-bank outlet and tidewater harbor provides for maximum use of land cuts, for a permanent retention dike across the sound and for jetties at the Gulf entrance. Id. at 37, ¶ 59. Ultimately, the land-cut channel was authorized in 1956 by Public Law Number 84^455, 70 Stat. 65 (1956) and was to be constructed “substantially in accordance with” the recommendation contained in the Chiefs Report. DX-0051 (Pub.L. No. 84-455, 70 Stat. 65 (1956)). The actual design and construction of the channel occurred in phases and in segments. The first segment approved was that which ran coterminously with the GIWW (Mile 63.77-Mile 68.85). JX-139 (Design Memoranda No. 1-A, Revised July 29, 1957). The second segment approved ran from the end of the east-west portion of the channel and turned southeastward cutting Bayou Bienvenue continuing on above Bayou La Loutre (Mile 63.77 to Mile 39.01). DX-1043 (Design Memorandum No. 1-B September 1958). The next segment ran approximately from Bayou La Loutre to the entrance of the Gulf (Mile 39.01 to Gulf Entrance) and the final portion was for certain retention dikes. DX-1042 (General Design Memoranda No. 2 (June 1959) at EDP-023-667). Its construction was completed to full dimensions in 1968. DX-1027 (1988 Reconnaissance Report) at 14, pdf 25; Doc. 19139 (United States’ Proposed Finding of Fact No. 777). A pictorial representation of these waterways can be found in Graphic No. 1 in the Appendix. Graphic No. 1— PX-98.2 “Greater New Orleans Flood Protection System”. Reach 1, Reach 2, the Golden Triangle, the Breach Zone and the Central Wetlands Unit Certain Mile Markers of the MRGO will be used as benchmarks in this opinion. Mile Marker 60 is at the very end of the East-West portion of the MRGO' — that which runs coterminously with the GIWW or Reach 1. It is at Mile Marker 60 that the “funnel” occurs — that point where the MRGO’s North-South leg, Reach 2, feeds into the GIWW. The geographic area to the east of this intersection is referred to as the “Golden Triangle” as the marsh area from that point to the west of the north-western shore of Lake Borgne resembles a triangle. The MRGO transverses Bayou Bienvenue at Mile Marker 59. Midway between Mile Marker 53 and 52 Bayou Dupre is transversed. The majority of the breaches to the MRGO Reach 2 Levee occurred between these two points (Mile Marker 59 to Mile Marker 52); that area will be referred to as the Breach Zone in this opinion. The Bayou La Loutre Ridge is located between Mile Marker 36 and 37. The Central Wetlands Unit is that marshland which is encircled at the north by the MRGO Reach 1 Levee, to the east by the MRGO Reach 2 Levee, to the south by the 40 Arpent Levee. The Verret Turn or the Chalmette Extension Levee protects those inhabited areas to the south of the 40 Arpent Levee; it extends from the MRGO at approximate Mile 47. See Graphic No. 2 — JX-0195 FitzGerald Report at 2-2, at pdf 12. 2. The Construction of the LPV At approximately the same time as the MRGO was on the drawing board, the Corps began to undertake the construction of the Lake Pontchartrain and Vicinity Hurricane Protection Plan. On June 15, 1955, following a series of severe hurricanes, Congress authorized the Corps to study projects to protect areas along the eastern and southern coasts from hurricane storm surges. JX-0446 (Douglas Woolley and Leonard Shabman, Decision-Making Chronology for the Lake Pontchartrain & Vicinity Hurricane Protection Project, March 2008) at § 2.2 at 2-3 (referred to hereafter at “HPDC.”). Included as a subject for study was the area surrounding New Orleans, which study came to be known as the Lake Pontchartrain and Vicinity Hurricane Protection Plan. (“LPV”) (HPDC, § 2.2 at 2-3 and 2.3.1 at 2-18) (See Public Law 84-71). In November of 1962, after seven years, an Interim Report produced the “Barrier Plan.” Central to the protection were tidal gates at Chef Menteur Pass and The Rigolets, which would be closed during storms to hold back surges that otherwise would enter Lake Pontchartrain. The Citrus area would have a new, low-level levee along the lakefront, flood-walls at the Inner Harbor Navigation (IHNC), and levees and floodwalls along the Gulf Intracoastal Waterway (GIWW). The Metro New Orleans area would have levee enlargement and flood-walls at the IHNC and the Seabrook lock at the mouth of the IHNC. The portion of Orleans Parish bordering St. Bernard Parish would get levees and floodwalls along the GIWW and the IHNC. The Chalmette area would get levees along the Mississippi River Gulf Outlet (MRGO) that would provide direct protection from [Standard Project Hurricane] SPH surges from Lake Borgne. By 1967, the area would be further protected by adding the Chalmette Extension to the project. HPDC § 2.3.5 at 2-29. This study utilized a model to determine necessary levee height and engineering needs known as the “Standard Project Hurricane” (“SPH”) which the Corps created in conjunction with the U.S. Weather Bureau to “select hurricane parameter of wind speed and central pressure for defining the SPH.” The LPV was to provide a degree of protection equivalent to the surge and wave action predicted to result from the SPH parameters. Also, taken into account was the “Probable Maximum Hurricane” (“PMH”) which was a stronger, although less likely event, than the SPH. The design of the project focused on SPH surge protection — the less forceful occurrence. (HPDC § 2.2 at 2-4; § 2.3.5. at 2-26-30). On September 9, 1965, Hurricane Betsy made landfall over Grand Isle Louisiana, due south of New Orleans, at nearly Category 5 strength. It moved up the Mississippi River which caused the river to rise ten feet at New Orleans. This storm caused catastrophic flooding around New Orleans, Chalmette and the Ninth Ward and provided an added impetus to proceed with the LPV plans. As the MRGO was substantially completed at the time of Hurricane Betsy, an action was brought against the United States for damages arising from that flooding alleging that the United States was negligent in designing, constructing and operating the Mississippi River Gulf Outlet. Ultimately, the district court found that plaintiffs failed to prove by a preponderance of the evidence any fault or negligence by the Government. Graci v. United States, 435 F.Supp. 189 (E.D.La.1977). In 1965, the “Chiefs Report” was transmitted to Congress. It included the reports of the Board of Engineers for Rivers and Harbors and the District Engineer. The report recommended the Barrier Plan and served as the basis for project authorization. DX-0610 (House Doc. 231, 89th Congress, 1st Session). The LPV was passed by Congress on October 27, 1965 as the Flood Control Act of 1965, 29 Stat. 1073, 1077 (42 U.S.C.A. § 1962d-5) three years before the MRGO was completed. Congress authorized the project for hurricane-flood protection on Lake Pontchartrain, Louisiana “substantially in accordance with the recommendations of the Chief of Engineers in House Document Numbered 231, Eighty-ninth Congress, except that the recommendations of the Secretary of the Army in that document shall apply with respect to the Seabrook Lock feature of the project.” Id. Thus, the Barrier Plan was put into place. It is pursuant to that authorization that the levees involved in this litigation were created. In August of 1966, the Corps reviewed its elevations of the levees with lessons learned from Hurricane Betsy in mind, and by September of 1968, it determined that the design elevations of all project structures were to be raised by 1 to 2 feet. This project was to face numerous obstacles and changes and indeed was not totally completed by the time Hurricane Katrina hit nearly 50 years later. As this Court has related in great detail in the context of the floodwall litigation in the LEVEE Master Class Action, In re Katrina Canal Breaches Consol. Lit (Levee Class Action), 533 F.Supp.2d 615, 621-624 (E.D.La.2008), the Barrier Plan was eventually scrapped for what was known as the High Level Plan. Under this alternative approach, rather than constructing barriers to prevent storm surge and salinity into Lake Pontchartrain, it was decided to raise the flood-walls in the outfall canals at Seventeenth Street, Orleans Avenue and London Avenue. These changes however, did not affect the construction of the levees that are salient to this case. The crucial levees at issue concern two areas. The New Orleans East Unit consists of those levees which were constructed along Reach 1 and the IHNC. They are known as the Citrus Back Levee, the New East Back Levee, the New Orleans East Levee and the Inner Harbor Navigation (IHNC) floodwalls. These levees protected New Orleans East. The second series of levees known as the Chalmette Area Unit are those constructed to protect the Ninth Ward and St. Bernard Parish. These levees consist of the MRGO Reach 1 Levee (which runs along the southern bank of the GIWW/ MRGO), the MRGO Reach2 Levee and the Verret Levee, also referred to as the Chalmette Extension. Collectively, the Court will also refer to them as the Chalmette levees. As noted, these levees, along with the 40 Arpent Levee (a non-Corps levee) create the boundaries for an area called the Central Wetlands Unit which plays an immense role in the case at hand. HPDC § 2.3.5 at 2-30. See Graphic No. 1 PX98.2 — Chad Morris Demonstrative Exhibit “Greater New Orleans Flood Protection System.” 3. MRGO Effects on the Environment Buried in various Corps’ reports some of which are discussed, infra, are unequivocal, positive statements that underscore the Corps’ knowledge that the MRGO would not be a static, unchanging waterway. It was clear from its inception that because of its location, degradation of the area would result unless proper, prophylactic measures were taken. In fact, some measures were included in the Corps’ plans; they simply were not implemented in time to prevent immense environmental destruction. a. Lateral Displacement, Sloughing, Wave Wake and Foreshore Protection Lateral Displacement and Sloughing As alluded to above, a seminal issue with respect to Reach 2 of the MRGO and the construction of the Reach 2 Levee abutting that waterway was the need for foreshore protection to protect the banks of the MRGO from wave wash. One of the significant factors making this a requisite had to do with the type of soil through which the channel was cut. In undertaking the construction of the MRGO, the Corps cut through “virgin coastal wetlands.” JX-0243 (Russo, Edmund, Independent Study: Evaluation of Bank Line Revetment Alternatives to Abate Ship Wake Erosion Mississippi River-Gulf Outlet, Louisiana) at 3. As such, the channel transected a deltaic plain created by the Mississippi River that consisted of low-elevation, forested swamps and marshes. Dr. Duncan Fitzgerald, an expert in Sedimentology, Coastal Processes and Coastal Geomorphology, Dr. Sherwood Gagliano, who testified as a fact witness but who is an accomplished geologist, physical geomorphologist and coastal scientist, and Dr. John W. Day, Jr, a Coastal Wetlands Ecologist, all provided convincing testimony concerning the geology and surface features of the subject territory, as well as the effects of the MRGO on the region. This marshland is made up of different types of soil and sediments, all of which have varying attributes. Under the marsh itself, much of Reach Two, and in fact, the majority of the Breach Zone is comprised of primarily interdistributary soil. This type of soil is also known “fat clay.” (Trial Transcript, Duncan FitzGerald, at 339). Fat clays contain a great deal of water and fine grain clay and are subject to a phenomenon know as lateral displacement — that is when loads are placed on this soil, it tends to compress and run toward a path of least resistance — not unlike when a person squeezes a tube of toothpaste. Another quality of this kind of soil is that it tends to “slough” or crumble slowly and fall away into water. The MRGO at the area of the Breach Zone was dredged to a depth such that its entire length is through an interdistributary strata. See Graphic No. 3, -JX-0195 (Expert Report of FitzGerald) at 6-3-6-4, at pdf 68-69. In 1958, the Corps noted that this type of soil would “probably displace laterally under fairly light load.” Id. at 6-2 citing USACE (1958) Plate 5. That information came from a paper prepared in February of 1958 by Charles R. Kolb and Dr. J.R. Van Lopik, of the Geology Branch, Soils Division of the Corps of U.S. Army Engineer Waterways Experiment Station. PX-059 (Geological Investigation of the Mississippi River-Gulf Outlet Channel “Geological Investigation”) at iii. This study’s purpose was to determine the soil types that might be encountered in excavating the channel. Id. at 1. The report concluded that “as much as 40 percent of the bottom and sides of the channel will consist of [ ] inter-distributary clays.... From the standpoint of side slopes this may appear desirable, but it is possible that poorly consolidated, high water content interdistributary clays will tend to flow laterally into the evacuation particularly under extra weight of a spoil bank.” PX-059 (Geological Investigation) ¶ 25 at 10. (FitzGerald Testimony at 350-52). Therefore, the Corps had knowledge that due to lateral displacement of soil into the channel, the Reach 2 Levee would incrementally lower. Moreover, the Corps knew that if the berm fronting the MRGO levee were armored, this effect would be substantially ameliorated. Wave Wash and Channel Widening The Corps was also aware that with the operation of the MRGO, a major force would be at play, threatening the integrity of the channel and the Chalmette Unit Levees. The banks of the channel were expected to slough primarily due to wave wash. This fact is underscored by Design Memorandum No. 1-B for the MRGO, penned initially in September of 1958 and revised in May of 1959 prior to the authorization of the LPV in 1965. The Corps noted that: 19. Channel protection. No channel protection is recommended initially; however, erosion due to wave wash in open areas can be expected in the upper part of the channel slope where the peat and highly organic clays are exposed. Protection for this area can be provided if and when the need for it becomes necessary. No channel protection is included in the overall cost estimate of the project.... PX-0699 (MRGO Design Memorandum 1-B (Revised 1959)) ¶19 at 5. Thus, the Corps knew that with time foreshore protection would be necessary because of the interaction between the MRGO and the LPV. What apparently was not clear to the Corps was precisely how soon the need for protection would be manifested. When a large ocean going vessel goes through a contained channel such as the MRGO it produces what is known as “wave wash,” a series of wave events, each of which has its own characteristics and each of which has great erosion potential. As described by Dr. Gagliano: During the passage of a large ship the lower shoreline is attacked first by the drawdown and return flow. As the drawdown occurs, water flows from the lower shoreline towards the center of the MRGO channel, causing erosion. Depending on tide level, water may also be drawn out of the marsh toward the channel. This can be a very turbulent and erosive process because of the head differential set up between the marsh and the channel. A similar differential causes hydrostatic pressure to be built-up in the exposed bank, forcing water to leave the soil. After the drawdown phase has been completed the return flow begins. From this point the water level along the shoreline will continue to rise until the original water level is exceeded. The return flow, being a flow of water back towards the shoreline, directly impacts both the lower shoreline and the exposed marsh bank. The diverging waves then begin to reach the shore as water elevation is at a maximum or mean level, continuing the attack on the upper shoreline. PX-0203 (The Mississippi River Gulf Outlet: A Study of Bank Stabilization (Dec. 1984)) at 5-1-5-2. The larger the ship, the larger amount of sloughing of the MRGO banks occurred and thus greater widening of the channel occurred. Accordingly, there is ample evidence to find that the dominant cause of erosion on the MRGO shore was ship waves produced by large oceangoing vessels. Id. at 4-19. (See Trial Transcript, Podany, at 3399). Thus, the recognized need for foreshore protection was not without reason. Wave wash would clearly result in the widening of the channel and therefore, increase the distance for waves to propagate, increasing the velocity of the flow of water, reducing the size of the berm protecting the Reach 2 Levee and in general placing the levee along Reach 2 in jeopardy. In fact, Mr. Edmund Russo, the Operations Manager for the MRGO from 2000 to 2005, opined in an article published in July of 2003: The channelized nature of the MRGO induces large ship waves during vessel passage. Ship waves strike the bank lines, which consist of very soft organic soils. Severe erosion occurs from these vessel wakes, and materials liberated in the process migrate into the waterway. MRGO bank erosion has historically and is currently occurring at high rates, mainly due to ship wave impact. An analysis of bank line retreat from 1964 to 1996 shows that the banks are being lost at about 12 to 26 ft/yr (Britsch and Ratcliff, 2001). Bank erosion results in channel shoaling, which requires periodic maintenance dredging. The current scenario is largely unsustainable from the engineering, environmental, and economic perspectives. JX-0243 (Russo, Edmund, Independent Study: Evaluation of Bank Line Revetment Alternatives to Abate Ship Wake Erosion Mississippi River-Gulf Outlet, Louisiana) at 3. Thus, a primary irritant with respect to the stability of the banks of the MRGO was wave wake, and the Corps’ failure to armor the waterway lead to deleterious, interconnected effects. The Court will now examine the Corps’ approach to this necessary prophylactic measure. South Shore Foreshore Protection As noted, the original MRGO authorization by Congress contemplated armoring the south bank of Reach 2 of the MRGO, and such action was officially authorized and approved by the Chief of Engineers in 1967. (Trial Transcript, Podany at 3421 and 3427). As this shoreline abutted the Reach 2 Levee, a responsible course of action to protect that levee being constructed and its berms from the shoreline’s erosion would have included this protection. The south shore protection was never subject to the need to find local participation in its funding as it had been made part of the GDM by supplement. Thus, the cost sharing concerns that arose with the passage of the Water Resources Development Act of 1986, (“WRDA”) were not applicable. (Trial Transcript, Podany at 3424-25 and 3427). Notably, by the time of the passage of the LPV enabling legislation in 1965, in the Report of the District Engineer which was prepared in November of 1962, the need for prophylactic action was recognized. “Riprap foreshore protection against erosion by wave wash from shipping will be provided.” DX-0610 (Report of District Engineer) at 65, pdf at 86 (emphasis added). Likewise, in the Board of Engineers for Rivers and Harbors July 1963 report, it was noted that riprap would be placed alongside the navigation channel. Id., at 9, pdf at 30. The United States has argued that this fact somehow makes the provision of foreshore protection part of the LPV with the inference that somehow this decision not to arm the banks would be immune under § 702c immunity of the Flood Control Act of 1928. (See ¶¶ 725-741). Such a characterization misses the mark. The fact remains that the failure to provide foreshore protection worked as the Navy vessel hitting the levee. It was a substantial factor in the failure of the Reach 2 Levee which all parties maintain were built to grade. General Design Memorandum No. 2, Supplement No. 4 for Foreshore Protection as submitted on 29 April 1968 provided a synopsis of the concerns as to whether ultimately the foreshore protection would be considered part of the LPV costs or the MRGO costs. While the Corps at one point took the position that it should be attributed to the LPV, the Chief of Engineers in Washington, D.C. ultimately decided that all of the cost of foreshore protection, not only on the south bank of the MRGO but also on the north bank of the GIWW, should be charged to the MRGO project. DX-1483 (MRGO GDM No. 2, Gen. Supp. No. 4 “Foreshore Protection” 29 April 1968, Appendix B, Inter-Agency Correspondence dated 24 April 67) at EDP-023-0965, at pdf 77. In a letter to the Honorable Carl Hayden, Chairman of the Committee on Appropriations for the United States Senate, H.R. Woodbury, Jr. Brigadier General of the United States of America, Director of Civil Works stated unequivocally “construction of the navigation project exposed these levees and the foreshore between them and the channel to direct attack with resultant damage from waves generated by seagoing vessel utilizing the waterway. The navigation project should have included adequate provisions for protecting these levees and their foreshore from this damage.” Id. Correspondence dated 27 November 1967 at EDP-023-969. While the levees referenced are not the Reach 2 levees, but are rather those that apparently already existed along Reach 1, it is clear that the paramount need for timely providing protection was obvious to the Corps. Ultimately, the Corps as rationale for its decision to charge foreshore protection to the MRGO stated in relevant part with respect to Reach 2: ... The MR-GO exposes the foreshore fronting this levee to direct attack by waves generated by oceangoing vessels. Therefore, providing the means for achieving the necessary erosion control for those areas, where such control is essential, is considered to be a function of the MR-GO project. By ENGCWOM 1st Indorsement (sic) dated 15 April 1966 to LMVED-A letter dated 21 March 1966, subject “Hurricane Protection-Lake Pontchartrain, La. and Vicinity — Chalmette Area,” the Chief of Engineers directed that the costs for foreshore protection contiguous to the levee plan for the Chalmette area along the MR-GO be charged to the navigation project. This directive was amplified ... [when in another letter] OCE concluded that the levee foreshore protection along the MR-GO is properly a feature of the Mississippi River-Gulf Outlet project, and the costs for such protection are, in their entirety, chargeable to that project. DX-1483 (MRGO GDM No. 2, Gen. Supp. No. 4 (“Foreshore Protection”) 29 April 1968), pdf version at 33-34 in ¶ 3, EDP-023-0921-22. Thus, the entire portion of foreshore protection of the Chalmette Unit fronting the MRGO project and for the back levee of the Citrus Unit from the S.W. corner to Station 507+44.6 was charged to the MRGO. The balance of the back levee of the Citrus Unit and the back levee of the New Orleans East Unit were determined not to be affected by wave wash from the MRGO and so not included. Id. pdf at 77-78, at EDP-023-0965-66. Dr. Robert Bea, one of plaintiffs’ experts concerning causation, testified that had the Corps employed foreshore protection before 1975, the lateral displacement process could have been prevented or at least slowed down. (Trial Transcript, Bea at 1151-52). Additionally, the significant widening of the channel would have been prevented. Nonetheless, from 1968 until 1982, nothing was constructed. It took 12 years for the Corps, in March of 1980, to determine that at this point that “due to technical problems related to extremely poor foundation conditions, additional study and revision of the original design [for foreshore protection] is necessary.” PX 794 (Letter from Col. Sands District Engineer to Jack Stephens, Director of St. Bernard Parish Planning Commission dated 25 March 1980). Thus, the failure to install timely necessary foreshore protection impacted the Reach 2 Levee itself as early as 1980. In fact, in a Memorandum dated January 29, 1981 to the LMVD concerning foreshore protection, the Corps noted that emergency bank repair work was required at the Bayou Dupre Control Structure. “This emergency work is needed at that location to arrest a serious problem that would impact the hurricane protection levee and the control structure.” PX-2122 at pdf p. 18 (AIN-108-1801). In this same memo from NOD to LMVD dated January 29,1981, the District Engineer reported on alternative designs for foreshore protection originally approved in July 3, 1968. He noted: The previous alinement (sic) plan for foreshore protection along the south bank of the MR-GO called for placement of riprap dike approximately 80 feet landside of the -5 contour. This plan is undesirable because of the irregular bankline condition that exists due to erosion and because of the large amount of foreshore dike settlement that would occur. PX-2122 (Letter from Col. Sands to LMV, Re: MRGO-Foreshore Protection dated 29 January 1981) pdf at 16, AIN — 1108-1799 (emphasis added). Two designs were proposed to be tested. These documents demonstrate that substantial erosion had already occurred which placed the MRGO levee in peril then. Thus, it is clear just from this testimony and documentary evidence that substantial areas of marsh had already disappeared by 1981. Finally, foreshore protection testing along the Reach 2 levee was begun in 1982 from Station 475 + 00 to Station 501 in Reach 2 along the Breach Zone. PX-338 (Disposition Form Narrative, Completion Report dated 3 Feb 83). This testing was apparently completed in February of 1983. In a handwritten memo penned on January 19,1983, and incorporated into a memo signed by Frederic M. Chatry, Chief, Engineering Division, to the Commander of the LMVD concerning the foreshore protection which had been a part of the relevant GDM since 1968, Chatry sought funding in the Fiscal Year Budget for 1985. A design still had not been settled upon. Nonetheless, he stated: The need for foreshore protection along the south bank of the MRGO is critical. Erosion along this reach caused by wave wash from ships using the MRGO has occurred at faster rates than originally anticipated. This erosion, if left unchecked, will begin to encroach into the stability berms of the Lake Pontchartrain Hurricane Protection Project’s Chalmette Area levees. In some areas the existing banks have eroded back to about 200 feet from the toe of the levee. PX-2122 (Letter to LMVD from Chatry dated 11 February 1983) at pdf 73-73 and 82 (emphasis added). On June 28, 1985, a contract was awarded to construct foreshore protection along the South Bank of Reach 2 from Station 367+60 to 1007+50 (roughly from Mile Marker 59 to Mile Marker 47). The contract was accepted as substantially completed on October 28, 1986. PX 337 (Disposition Form Narrative, Completion Report dated 7 November 1986). By 1988, the Corps reported that the “13 miles along the south bank from Bayou Bienvenue to the end of the leveed reached as authorized by the August 1969 project modification had been completed.” See DX-1057 (MRGO Reconnaissance Report Feb. 1988) at 14. Interestingly, there are documents further indicating that even that protection was not sufficient to the task. The Court reviewed a foreshore protection repair document for the South Bank from Mile 59.4 to 47.0 dated June 7, 1993 (DX-1067); a foreshore protection repair document for Mile 59.4 to Mile 56.0 dated December 29, 1993 (DX-1068); a foreshore repair document for Mile 59.2 to 55.2 dated September 12 1994 (DX-1069); a foreshore repair document for Mile 58.7 to 53.6 dated June 13, 1995 (DX-1071); a foreshore repair document for Mile 59.8 to 59.4 dated March 21, 1996 (DX-1072). These repair documents continue into 1999; however, some documents do not definitively indicate that the repairs are to the South Bank. DX-1073, DX-1074, DX-1076, and DX-1079. Obviously, the Corps knew that the MRGO was causing severe erosion continuously — even to the point that the attempts at protection were not withstanding the currents. It is not surprising that when commenting on the poor relations with St. Bernard Parish and the landowners adjacent to the MRGO in 1999, Robert L. Gunn, the Operations Manager for the Corps at NOD in “Mississippi River-Gulf Outlet Environmental Disaster or Valuable Economic Port” stated, “[i]n the past the Corps of Engineers did little to explain the proposed annual maintenance of the project. The foreshore protection, which protected vital hurricane levees, was not maintained properly or timely.” (PX-722 at NOP-013-3317). North Bank Foreshore Protection As to the North Bank, no foreshore protection for the North Bank of Reach 2 was forthcoming until the 1990s by which time catastrophic damage to the wetland banks of the MRGO had occurred. (Trial Transcript, Russo at 3574). It is clear that the Corps had knowledge by the early 1970’s that protection was necessary. The extreme loss of wetlands particularly along the North Bank abutting Lake Borgne was recognized in 1973. At extreme risk was the land bridge which prevented Lake Borgne from flowing directly into the MRGO which could catastrophically magnify the force and intensity of storm surge and wave propagation that could occur in the context of a substantial hurricane. PX 1633 (Statement for Rivergate Public Meeting 30 August 1973) at 13. Nonetheless, Col. Early J. Rush, II who served as the NOD commander from 1974 through 1978, testified that he could not recall ever forwarding anything up the chain of command discussing the bank erosion problem which clearly was significant by that time. (Trial Transcript, Rush at 252). Indeed he stated that he never got “any information along that line that there was a major problem.” (Trial Transcript, Rush at 254). This testimony was incredible in light of the fact that on July 15, 1976, the Corps issued a public notice concerning foreshore protection for the Citrus Back Levee along Reach 1 which was in fact signed by Col. Rush. (PX-1344). In addition, he signed an 18 April 1978 memo to LMVD concerning North Bank protection (Citrus Back Levee) in which he stated that South Bank [fronting the Chalmette Unit levees] foreshore protection would be addressed in a future report with construction scheduled to begin in 1980. DX-1483 (General Design Memorandum No. 2, Supp. 4 Foreshore Protection) at EDP-023-0893-95. Moreover, as will be discussed, supra, the land loss was patently visible. Furthermore, the amount of dredging that had taken place to that point would have placed the Corps on notice of the problems with sloughing that the operation of the MRGO was creating. From 1966 to 1972 the Corps spent $3,466,528 in maintenance dredging. PX-1630 (Environmental Impact Statement, October 1972, Gagliano) at 17. Nonetheless, the Corps clearly took the position that its primary mission was to keep the shipping channel open to deep draft traffic regardless of the consequences. (Trial Transcript, Podany at 3395-96; Trial Transcript, Sands, at 265). In questioning Tom Podany, the Corps’ witness concerning reports of the Corps’ efforts to investigate measures directed at bank stabilization along the MRGO, it is clear that the Corps’ focus was narrow; mitigation was looked at only from the perspective of how it would effect maintenance costs. Id. In conducting these studies neither was a dollar amount assigned to the value of human life nor to the cost of the destruction of property. Id. Furthermore, the Corps did not include these values in its equations to prioritize projects for funding. (Trial Transcript, Podany, at 3344-46). Also, after the passage of the Water Resources Development Act, 33 U.S.C. § 2201, et seq., the Corps, for the most part, took the position that there would always need to be local participation in the cost of any study, and consequently, any corrective action to be taken as concerned the North Shore foreshore protection. In September 1979, the Corps of Engineers received two requests, one from Representative Robert L. Livingston, Jr. and the other from Senator Russel Long, both of Louisiana and both asking the Corps to respond to concerns about bank erosion along the MRGO, in particular the development of a north shore levee using MRGO dredge spoil. PX1033, PX-1034 (Letters of Long, Livingston to Col. Sands). (Doc. 19139, United States Findings of Fact No. 807). Rather than addressing the issue of damage directly, the Corps responded solely to the proposed fix — use of spoil — and opined that there was no federal authority to create erosion protection. In 1982, Congressman Livingston initiated the passage of a resolution directing the Corps to look into the feasibility of bank foreshore protection along the north shore. DX-1027 (1988 Reconnaissance Report) at 2, pdf 13. It was not until February, 1988 that the ensuing report issued. In the meantime, the Corps conducted a study issued in 1984, “Notice of Study Findings for the Louisiana Coastal Area, Louisiana, Shore and Barrier Island Erosion, Initial Evaluation Study, July 1984” (PX1639) in which the Corps stated: Construction of the MR-GO has accelerated the natural changes occurring in the St. Bernard Parish wetlands near Lake Borgne.... Wind- and wave-generated erosion is also steadily widening the MR-GO. Because of this expansion, the east bank along Lake Borgne is dangerously close to being breached. Once the bank is breached, development to the southwest would be exposed to direct hurricane attacks from Lake Borgne, the rich habitat around the area would be converted to open water, and more marsh would be exposed to the higher salinity water. (PX-1639 at 7). Then, the Corps outlined two possible erosion control plans. Id. at 8. (Trial Transcript, Podany at 3411-3413). With its 1988 federally funded study, “Mississippi River-Gulf Outlet St. Bernard Parish, La. Bank Erosion Reconnaissance Report, February, 1988,” the Corps reported: Most of the Mississippi River-Gulf Outlet is experiencing severe erosion along its unleveed banks. The erosion is a result of both man-induced and natural forces, including combinations of channelization, ship and wind generated waves, storm activity, and subsidence. Associated with subsidence is eustatic sea level rise that has been estimated at 0.5 feet per century (Nummendal, 1983). Subsidence and sea level rise intensify saltwater intrusion and erosion. The marshes along the north bank of the Mississippi River-Gulf Outlet have been especially hard hit by these forces and are disappearing at an alarming rate. Because erosion is steadily widening the MR-GO, the east bank along Lake Borgne is dangerously close to being breached. Once the bank is breached, the following will happen: sediment for Lake Borgne will flow into the channel resulting in large increases in dredging costs to maintain the channel; development to the southwest would be exposed to direct hurricane attacks from Lake Borgne; the rich habitat around the area would be converted to open water; and more marsh would be exposed to higher salinity water. DX-1057 (Mississippi River-Gulf Outlet St. Bernard Parish, La. Bank Erosion Reconnaissance Report, February, 1988) at 10-11, pdf 63, EDP-023-1033-34. (emphasis added). So, 15 years after the Corps was aware of the extreme loss of wetlands, e.g. the Hsu and Gagliano reports at a minimum, the Corps finally acknowledged in two internal documents the need for north shore protection; however, there was still no attempt to seek funding based on the recognition that the inhabitants of the area were at risk just as Dr. Gagliano foretold in the 1970s. Furthermore, any argument that this degradation was being caused by “natural” subsidence is suspect. The dynamics causing the widening of the MRGO and the marsh erosion of the north shore were only minimally affected by natural subsidence. Furthermore the rate of subsidence was significantly greater at the MRGO than in other areas demonstrating further its harmful effects. Duncan FitzGerald testified that the rate of subsidence at the MRGO area is 17.6 millimeters per year, where the average subsidence in the area is 5 to 6 millimeters per year. Therefore, the subsidence rate of the MRGO is 3 to 5 times the rate of the surrounding regions in the New Orleans area. (Trial Transcript, FitzGerald, at 396). The 1988 report concluded that the current bank erosion problem was to become a major maintenance issue requiring a six-times increase in the required average annual maintenance dredging by 2002. Id. at 54. Finding this hook, the NOD engineers recommended that the matter should be addressed as a supplement to the General Design Memorandum which would encompass further studies including a feasibility study and would not require local participation. (Trial Transcript, Podany, at 3370). However, upon submission to the LMVD, the LMVD maintained that the modeling used to create the economic justification under the GDM was incorrect, that the anticipated dredging would be half the cost of what the 1988 Reconnaissance Report stated, and as such, a GDM approach modification was not justified. Thus, even though the shoaling rates were still anticipated to be 3 times the amount that they had been in the past, which was significant, the Corps took the position that under the benefit-cost ratio, it did not warrant a GDM modification approach. (Trial Transcript, Podany, at 3371). While the Corps conducted studies acknowledging the erosion problem and the need for foreshore protection in 1984 and in 1988, until the cost of providing foreshore protection proved to be less expensive than the continued need for dredging to maintain the channel’s navigability, the Corps did not actively pursue funding for this protection. It is apparent that the Corps refused to undertake any foreshore protection project unless it was conducted pursuant to WRDA requiring local participation even though there were other methods by which the Corps could have taken some action — that being seeking a supplement to the General Design Memorandum to directly and swiftly address the erosion issue. (Trial Transcript, Podany at 3424-3429). Implicit in Mr. Podany’s testimony is the sense that these decisions were all based on policy considerations. However, when the safety of an entire region is at stake, negligence cannot be masked by policy. Indeed, his testimony rings hollow considering the Corps had acknowledged that south shore foreshore protection was to be charged against the MRGO as early as 1967 and again recognized in 1968. DX-1483 (MRGO GDM No. 2, Gen. Supp. No. 4 “Foreshore Protection” 29 April 1968, Appendix B, Inter-Agency Correspondence dated 24 April 67) EDP-023-0965 or at pdf version at 77 and EDP-023-0921-22 or at pdf version at 33-34 in ¶ 3. Clearly, from the first recognition of erosion, the Corps neglected the north shore of Reach 2. The Corps’ sole focus vis foreshore protection became providing protection for the south shore which was accomplished at a deleteriously slow pace. The north shore erosion was ignored because there was no levee to protect from the harm of the MRGO and because the sole focus of the Corps was to guarantee the navigability of the channel without regard to the safety of the inhabitants of the area or to the environment. The reality of this myopic and telescopic approach is demonstrated by the Corps’ practice with respect to the reporting required by the Environmental Protection Act, which will be discussed, infra. Moreover, the argument by the Corps that any measure to be taken for foreshore protection would have required approval by Congress, seems inconsistent with the Corps’ use of the Chiefs “discretionary authority” to change dramatically the LPV from the Barrier Plan to the High Level Plan. Even with the knowledge that the erosion problem was potentially cataclysmic for the lives and property of those who lived in St. Bernard Parish, no move was made to use the Chiefs discretionary power to supplement the GDM to provide foreshore protection. Furthermore, never did the Corps prioritize this need or apprise Congress directly of the possibility of disaster that the MRGO created. (Trial Transcript, Podany at 3403-04; Trial Transcript, Peter Luisa at 3615-17; 3624-26). Never was any direct funding approach taken even when the Corps knew it had triggered catastrophic erosion caused by the very channel it had created. Apparently, in 1991, the State of Louisiana would not sign off on a Coastal Zone Management decision for marsh nourishment and restoration, because the plan did not address severe bank erosion failing a guideline. Instead, the state was insisting on stone dikes for protection. In its own discussion points as to why the banks should or should not be stabilized, the Corps listed as its second reason not to stabilize, “Corps (sic) long standing policy against repairing bank erosion.” PX-2082 (Memo to Headquarters of the Army Corps of Engineers about the Coastal Zone Management Realm, May 30, 1991) at pdf 2, NOP 007-780. The Court finds Mr. Podany’s self-serving explanation that this written statement did not mean what it says without weight. He was not involved in the writing or drafting of the memo and had not read it before testifying. Also, in 1991, Congress approved the funding of construction of dike bank protection, “MR-GO North Bank Protection, Mile 50 to 54.” This project provided protection from channel mile 51 to mile 54.1 and was completed in March of 1993. DX-1747 (Mississippi River-Gulf Outlet, Louisiana North Bank Foreshore Protection Evaluation Report, October 1996) at 11-12, pdf 24-25, NOP-002-1333-34. This stretch is the land bridge of Lake Borgne and is the section of marsh which the Corps identified as being at risk since the 1988 Reconnaissance Report. See DX-1762 (Excerpt: page 1381 of DX 1747, Plate 3 taken from the 1996 Evaluation Report)(delineated as Existing Protection MI 54.1-51). The project was specifically authorized by Congress; ironically, it appears that when the Corps finally deemed something an emergency, Congress came through. (Trial Transcript, Podany, at 3377). The protection construction was begun in 1992 and was completed in March of 1993. DX-1747 (Mississippi River-Gulf Outlet, Louisiana North Bank Foreshore Protection Evaluation Report, October 1996) at 32. Mr. Podany testified that by 1995, the Corps found that the actual cost of maintaining the foreshore protection was considerably below the estimate used in the 1988 report. Thus, a re-analysis of the benefits and costs based on this new cost information was the genesis for an April 1996 Evaluation Report. Id.; (Trial Transcript, Podany at 3377-78). Nonetheless, before that 1996 Evaluation Report was issued, another Reconnaissance Report was published in 1994, six years after the first Reconnaissance Report. In this report, the Corps was still operating under the mistaken assumption that the cost of the protection was greater than it proved to be. As such, rather than recommend the cost of protection be budgeted as a supplement to the GDM, the Corps took the position that the costs for these bank stabilization matters should be shared by the local population. Yet, the same drumbeat and warnings appear in this report. It reported that since 1968, bank erosion had resulted in the loss of approximately 4,200 acres of highly productive marsh adjacent to the MRGO channel. Again, its focus was in a cost-benefit analysis with respect to the need for dredging caused by shoaling. The only difference was that now the Corps recommended that the local cost sharing burden be 30 percent for the feasibility phase, 15 percent for the construction phase and 60 percent for the operation and maintenance phase. DX-1058 (Mississippi River-Gulf Outlet St. Bernard Parish, La. Bank Erosion Reconnaissance Report, January, 1994) at 2, pdf 3. No local sponsor was found. (Trial Transcript, Podany at 3373). Returning to the 1996 Evaluation Report, significantly, an Evaluation Report, unlike a Reconnaissance Report, does not require local funding and was funded through the operation and maintenance budget. The Corps again in this report, acknowledged the harm that wave wash was causing to the unprotected banks: Severe bank erosion is occurring on the MR-GO navigation channel. Approximately 43 miles of the 66 mile long channel consists of a land cut through unstable marsh and shallow water areas. Since its completion in 1968, the top width of the channel has increased from 650 feet to an average of 1,500 feet, in 1987 [10 years before this study], principally due to erosion. The channel banks have eroded beyond the existing channel right-of-way in several locations. Much of the bank erosion is caused by wave-wash and drawdown from large displacement vessel traffic on the restrictive waterway. Passage of these vessels causes very large quantities of water to be displaced from the channel into the adjacent marsh, followed by rapid return flow into the channel. The tremendous forces exerted by these rapid and extreme water level fluctuations cause the relatively soft marsh adjacent to the channel (mostly on the north bank) to break up and be swept into the waterway. Since 1968, bank erosion has resulted in the loss of approximately 4,200 acres of highly productive marsh adjacent to the MR-GO channel. Continued erosion threatens to produce large breaches in the rapidly dwindling marsh buffer between the navigation channel and the open waters of Lake Borgne and Breton Sound. Once the buffering marshes are lost, dredging frequency and quantity in the vicinity of the breached bank will increase significantly. The navigation channel will be exposed to storms, currents and less attenuated tidal action from the north and northeast. Attendant sedimentation and shoaling problems are expected to occur. DX-1747 (Mississippi River-Gulf Outlet, Louisiana North Bank Foreshore Protection Evaluation Report, October 1996) at N OP-002-1317-18. The report supported the funding of a stretch of protection along five 5 critical “reaches” or sections of the North Bank. Of these, only three were completed. The Corps opined: The buffering marsh between the MR-GO and Lake Borgne is eroding at approximately 15 feet per year, and this reach of the MR-GO north bank is very close to being breached. However, only a 3.5 mile section of the MR-GO north bank includes erosion protection measures. Consequently, the vast majority of bank continues to erode rapidly. At the current average rate of bank retreat, approximately 55 acres of intermediate/brackish marsh, adjacent to the north bank of the MR-GO are being converted to open water annually. MR-GO bank erosion, if left unchecked, will result in the loss of approximately 2,700 acres of coastal marsh between the years 2000 and 2050.... As the marsh within the project area diminishes, significant losses to marsh dependent fish and wildlife species will also occur. Increases in water levels, resulting from the general rise in sea level and subsidence of the land will enlarge land/water interface and accelerate saltwater intrusion. The precise effects of vessel traffic on channel erosion were not considered in this study. Id. at 26-27 or NOP-002-1348 (emphasis added). Thus, regardless of the fact that the Corps knew that the simple operation and use of the channel caused this kind of devastation because it had not armored these banks, nothing was done in a timely fashion. Mr. Podany testified that not until as noted in the 1996 Evaluation Report “we were given guidance from Congress to look at available operation and maintenance funding and look at whether that could be used to do bank stabilization.” (Trial Transcript, Podany at 3373). That “guidance” came from United State House of Representatives, Energy and Water Development Appropriations Bill, 1996, 104th Congress, 1st Session, in which Congress stated: The Committee is aware that the authorized 36-foot Mississippi River-Gulf Outlet channel is experiencing serious bank failures on its north bank due to land subsidence, which is significantly increasing dredging costs. The Committee is aware that the Corps of Engineers recently experienced dredging delays, which caused draft restriction, while attempting to resolve environmental issues in the process of obtaining Coastal Zone consistency to dredge the Mile 50-56 reach. To resolve this particular issue the only available solution was to construct a rock dike that provided bank stabilization before dredging could be accomplished. The Committee is of the opinion that to minimize future dredging costs and preserve wetlands, the north bank Mississippi River-Gulf Outlet should be stabilized with riprap or similar hardened protection, as necessary, using available operations and maintenance funds. DX-1747 (Mississippi River-Gulf Outlet, Louisiana, North Bank Foreshore Protection, Evaluation Report, October 1996) at 3. So basically, once Congress was made aware of the problem by the Corps, Congress instructed the Corps to fix it. Again, the “crisis” was pitched in the context of the viability of the channel; there is no indication that the Corps had informed them specifically of the findings of the Reconnaissance Report of 1984 and that safety’s needs required action. Thus, it is clear from the testimony and documentary evidence that the Corps knew at least from the early 1970’s that the MRGO was endangering the Chalmette Unit Reach 2 Levee. It knew that a primary source of the devastating shoaling was as a result of the wave wash that occurred with each ship that navigated the channel. Even though it was determined unequivocally in 1968 that the funding for the South Bank would be under the MRGO rubric, until 1982 nothing was done and it was not completed until 1986. As to the north shore, the callous and/or myopic approach of the Corps to the obvious deleterious nature of the MRGO is beyond understanding. b. Salinity Issues Similarly, increased salt water intrusion and its effects on the environment was another product of the MRGO. In creating the channel a number of ridges which provided protection from saltwater intrusion through tidal shifts were cut. “Narrow, low elevation ridges are the natural levees of active or formerly active distributaries of the deltaic plain that locally separate these swamps and marshes from one another.” JX-0195 (FitzGerald Expert Report) at 6-1. These ridges provided a natural barrier for salt water intrusion from the Gulf of Mexico; with their trans-sectioning, an adverse habitat change occurred. (Trial Transcript, FitzGerald, at 298.) The largest ridge cut by the Corps was the La Loutre Ridge which is found in between Mile Marker 36 and 37. JX0195 (FitzGerald Expert Report) Figure 2.3 at 2-2. This ridge is south of Lake Borgne and runs in an east-west direction. It was approximately 10 feet in height which allowed for the growth of substantial trees and vegetation and was between 200 to 300 feet in width (Trial Transcript, FitzGerald, at 301-302). With the cutting of this and other ridges (those which accompanied Bayou Bienvenue and Bayou Dupre) substantial damage had occurred by the late 1960s. (FitzGerald Report at 2-7). In essence, marshes that contained larger and denser vegetation gave way to marshes with less dense vegetation which would result in reduced friction in the event of water surges. (Trial Transcript, FitzGerald, at 308-11). Dr. John W. Day also testified and demonstrated that in 1956 the marshes, be they fresh or non-fresh, were low salinity marshes. They had a variety of flora which were tall and dense and would have had a greater impact on surge than the uniformly low marshes of three to four feet as it exists in that area now. He also noted that the 1956 habitats of this area were virtually gone by 1976. According to the Corps’ own observations, it recognized that coastal habitats can generally reduce surge by one foot for every 2.75 miles thereof. (Trial Transcript, Day at 685, 687-88); see also (Trial Transcript, Bea, at 1196-1197). In addition, the roots of the existing vegetation which created the glue for the marsh soils died and degenerated causing further soil loss. (Trial Transcript, FitzGerald, at 308-311). In the Report of the Board of Engineers for Rivers and Harbors to the Chief of Engineers of the Department of the Army, dated 24 July 1963 with respect to the LFV (“Board of Engineers Report on the LPV”), it stated the following: 11. Improvements proposed. — The reporting officers find that the most suitable plan for controlling salinity exchange and velocity of flow in the Inner Harbor Navigation Canal, caused by construction of the Gulf Outlet, would be by construction of a lock at Seabrook, on the lake end of the canal.... The first cost of the lock and the annual cost of its maintenance and operation, shown in Table 1 hereto, would be Federal and are mitigating costs of the Gulf Outlet project. DX-0610 (Chiefs Report) at 9, at pdf 30 (emphasis added). Thus, while the Corps recognized a salinity problem, its focus had more t
