BEFORE: BATCHELDER, STRANCH, and MURPHY, Circuit Judges.
MURPHY, Circuit Judge. One clear July day, a towboat making its way to the Mississippi
River ran aground on the foot of Mud Island in Memphis, Tennessee. The vessel left large holes
on Mud Island’s banks. The City of Memphis and its agent, Riverfront Development, Inc., invoked
the district court’s admiralty jurisdiction to bring this negligence suit against Wepfer Marine, Inc.,
the owner of the grounded vessel. After finding Wepfer liable for the grounding, the district court
awarded $1,145,990 in damages. Wepfer now challenges only the damages ruling. For the most
part, we reject Wepfer’s claims under our deferential standard of review. But the district court did
commit one clear error in calculating the damages award. We thus reverse the judgment and
remand for entry of an amended award consistent with this opinion. No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
I
A
Mud Island sits in Memphis, Tennessee, where the Wolf River Harbor meets the
Mississippi River. It is not in fact an island, but a peninsula running north-and-south down the
Tennessee side of the Mississippi River. To the island’s west lies the Mississippi River and then
Arkansas; to its east lies the Wolf River Harbor and then downtown Memphis. Mud Island’s
undeveloped southern tip juts out where the Wolf River Harbor meets the Mississippi.
On July 6, 2015, Captain Jared LaFrance was piloting the M/V Lucy Wepfer southbound
through the Wolf River Harbor toward the Mississippi. The Lucy Wepfer pushed a barge loaded
with concrete slurry. LaFrance intended to make a “U-turn” and steer his vessel northward up the
Mississippi River. As he entered the Mississippi, Mud Island was to his starboard (right) side.
The Mississippi was high that day, and Mud Island’s southern tip was submerged. LaFrance made
his starboard turn into the Mississippi prematurely, and the Lucy Wepfer ran aground on Mud
Island’s submerged southern tip. In the language of admiralty law, this was an “allision,” which
“occurs when a moving vessel strikes a stationary object[.]” Bessemer & Lake Erie R.R. Co. v.
Seaway Marine Transp., 596 F.3d 357, 362 (6th Cir. 2010). The Lucy Wepfer and the barge were
extracted after some effort. The water’s later receding revealed two large gashes on Mud Island’s
eastern shore.
B
Riverfront Development, Inc., Mud Island’s managing agent, sued Wepfer Marine, Inc.,
the Lucy Wepfer’s owner, for negligence. Riverfront sought to recover the costs of repairing the
damage to Mud Island. The City of Memphis later intervened as a plaintiff. (The distinction
between the two plaintiffs does not matter on appeal so we will refer to them both as “Riverfront.”)
2 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
The district court determined that Wepfer was fully liable and that the proper measure of damages
was restitutio in integrum—the cost of restoring Mud Island to its previous condition. The
Baltimore, 75 U.S. 377, 385 (1869).
The district court held a hearing to establish the cost of repairing Mud Island. Following
the grounding, the Mississippi’s rising and falling waters had started filling the holes with
sediment. The parties disputed whether this sediment needed to be removed to restore Mud Island
to its original condition. Wepfer argued that the sediment was the same material that had built
Mud Island and that the river would naturally refill the holes. Alternatively, Wepfer contended
that it needed only to pay to fill the holes above the sediment. Riverfront, by contrast, maintained
that the accumulating sediment would not restore Mud Island to its original condition. It wanted
to excavate the sediment so that the holes could be “filled and packed by human intervention with
sand and/or limestone.” At the hearing, then, the district court needed to resolve (a) the volume
of the holes; (b) whether the sediment needed to be removed; (c) the material that should be used
to fill the holes, if any; and (d) the total cost of the repairs.
1. Volume. The parties debated the size of the two large holes. Both sides measured the
holes within eight months of each other.
James Reeder, a Riverfront project director with a bachelor’s degree in civil engineering,
first measured the holes in November 2016, about 16 months after the accident. Reeder explained
his process. Using a “tape measure and electronic devices,” he “divided the two gouges into five
different areas” and then “took measurements of these five parts . . . and came up with the cubic
yardage.” Reeder estimated the holes’ irregular depths by using “engineering judgment” and his
own height as a reference. Based on rounded-up measurements, he calculated the volume of the
holes as 10,000 or 10,100 cubic yards. When Reeder sought a quote for refilling the holes, he
3 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
added a 20-percent contingency to account for “compaction” of the material. This contingency
was necessary, Reeder explained, “because a lot of times when you fill up holes, you have material
that’s not compacted and you have to buy more material than what is the volume of the hole. So
when you end up compacting it, you have to have 20 percent more material to get to the final
grade.” That resulted in a total volume of 12,000 cubic yards of fill material to fill the 10,000 or
so cubic yards of holes.
Wepfer hired Ollar Surveying Company to measure the holes again eight months later in
July 2017. The court recognized Douglas Swink, the surveyor, as an expert in the fields of land
surveying, topographic surveys, slope analysis, and soil analysis. Swink measured the holes using
common surveyor methods. He calculated their volume as 2,792.30 cubic yards, a number that
fell more than 70 percent below Reeder’s. But all agreed that Ollar’s measurements were more or
less accurate in July 2017.
The disparities in measurements mattered greatly to Wepfer, as they suggested the amount
of sediment accumulating in the holes. Wepfer tried to paint Reeder’s earlier tape-measure
calculations as unsophisticated and inaccurate. Even Riverfront’s expert opined that it did not
“seem very likely” that the holes could have filled with over 7,000 cubic yards of sediment in eight
months. Benny Lendermon, Riverfront’s former president and a civil engineer, also agreed that,
when he saw the holes in March 2017 (after Reeder’s measurements but before Ollar’s), it appeared
that they “had filled in very little[.]” But Riverfront’s witnesses also suggested that erosion and
“sloughing” (instability of the holes’ slopes) could account for some of the accumulation.
2. Excavation. The parties next debated whether the accumulated sediment needed to be
removed before refilling the holes.
4 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
Riverfront’s witnesses testified that excavation was necessary because Mud Island is made
of sand and the sediment accumulating in the holes was “muck.” Those witnesses included Reeder;
Lendermon; and Clinton S. Willson, a professor of civil and environmental engineering. Dr.
Willson testified that Mud Island, in its present form, is largely made of sand. Around the turn of
the twentieth century, it was little more than a sand bar. But today, he explained, it is “a highly
engineered system” composed of “dredged material that was . . . placed in a way that would allow
for . . . development[.]” The dredged material was mainly “granular sand” from the bottom of the
Mississippi River.
While Mud Island is made of sand, Riverfront’s witnesses testified that the sediment
settling in the holes was likely “muck.” They admitted that they did not test the sediment to
determine whether it was muck or sand—the most accurate way to answer the question. But they
explained why they believed it was muck. According to Dr. Willson, the Mississippi carries a
range of sediments, from “large course-grain sand, down through medium, fine, very fine sand,”
and then “down into silts and clays[.]” The heavier sand settles near the river bottom. The finer
material is no match for the Mississippi’s current and so remains afloat. The Wolf River Harbor,
by contrast, has little to no current. An eddy thus forms as the Mississippi’s current meets the
Wolf River Harbor’s stagnant water. The Wolf River Harbor’s lack of a current allows the
Mississippi River’s fine materials to settle, resulting in “more loose material”—known as
“muck”—accumulating in the harbor. Because the holes were on Mud Island’s harbor side,
Riverfront’s witnesses testified, it was highly likely that they contained the settling muck rather
than sand.
Riverfront’s witnesses added that muck is not a suitable replacement for sand. Dr. Willson
defined muck as “typically some combination of water, mud, organic material . . . very fine
5 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
particles.” It has very little “integrity in terms of being able to step on it, in terms of loading on
top of it.” He explained that “there’s a big difference between the [structural] stability of the clay
and the stability of the sand.” Lendermon agreed, and described a riverfront development project
near Mud Island in which the builders allowed “too much silty material” to mix with the sand.
“[T]hat soft material there was creating a sliding plane that created no stability” and resulted in “a
major failure of [a] dike.”
To dispute these points, Wepfer presented evidence that Riverfront needed to undertake no
excavation because the holes were filling with the same material used to build Mud Island. Dr.
Charles Morris, an expert in river engineering, agreed that Mud Island had been built of dredged
Mississippi River sand. But Dr. Morris believed that the sediment now filling the holes was
“mostly sand,” not muck. Because Mud Island sat on the outer side of a Mississippi River bend,
he explained, it was more likely for sand to be deposited on the island’s foot. On the bend’s inner
side, closer to Arkansas, the water travels at a slower rate. But the water on the bend’s outer side
accelerates as it travels more distance. When the water is “flowing faster,” Dr. Morris explained,
“it carries sand with it.” In Dr. Morris’s opinion, the fast-flowing water was depositing sand on
Mud Island. He did not think “human intervention” was necessary to return the holes to their
original condition
Riverfront called Dr. Willson in rebuttal. In his view, the higher speed in the bend creates
“a corkscrew effect of the flow. So if the flow is trying to go around the bend, it’s also then
corkscrewing back under down to the bottom of the river.” That phenomenon would push the sand
away from Mud Island toward Arkansas.
3. Materials. The parties also debated the materials that would be suitable to refill the
holes. The two options were sand ($43.50 per cubic yard) and limestone ($37 per cubic yard). In
6 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
its pretrial brief, Riverfront requested the more expensive sand. All witnesses agreed that both
sand and limestone would be acceptable. A Riverfront witness, Lendermon, testified that
limestone was “certainly” suitable, and that sand would be “suitable as long as you can hold it in
place.” Dr. Willson also thought that “some kind of construction-grade limestone” or “maybe
sand” would be appropriate fill materials. He could not say that “one or the other is better.” Dr.
Morris, Wepfer’s expert, believed limestone was “a sufficient material”; indeed, he testified that
limestone would make the island “much more stable” than it was before and so “would be an
enhancement to stability.”
4. Costs. Riverfront lastly introduced the sole estimates that it had received to repair Mud
Island. Luhr Brothers, Inc., estimated a cost of $623,990 for excavating 9,208 cubic yards of
material. The company received that 9,208 number from Reeder. To calculate this number,
Reeder started with his 12,000 cubic yard estimate—an estimate that included both the size of the
holes that he had measured (about 10,000 cubic yards) and the 2,000 cubic yards worth of extra
fill material needed because of compaction. Reeder then subtracted 2,792 cubic yards—the size
of the hole that Ollar later measured in July 2017.
The cost estimate for refilling the holes with limestone was $444,000, while the cost to
refill with sand was $522,000. These amounts were based on 22,000 tons of fill material reflecting
12,000 cubic yards—the quantity of fill that Reeder had initially calculated.
C
The district court’s damages order awarded Riverfront “the cost of excavating and refilling
the depressions caused by Wepfer’s negligence.” It credited Riverfront’s witnesses that the
sediment filling the holes was “muck” and thus that Riverfront needed to excavate it. It noted that
Wepfer’s alternative theory that the accumulated sediment was sand did not “overwhelm[]”
7 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
Riverfront’s “substantial evidence” to the contrary. The court next accepted Reeder’s initial
measurements as an acceptable estimate of the original size of the holes, and seemingly used
Ollar’s later measurements to conclude that the holes had filled with roughly 9,208 cubic yards of
sediment. It also found that Riverfront had established sand as an appropriate material for refilling
the holes. Finally, the court found the cost of repair to be essentially uncontradicted, and accepted
Luhr Brothers’ estimates. It entered a judgment awarding Riverfront $1,145,990 in damages.
Wepfer filed a motion to alter or amend the judgment under Federal Rule of Civil
Procedure 59(e). The court denied the motion, concluding that it sought “a wholesale relitigation
of the case” and raised “no new arguments.”
II
On appeal, Wepfer challenges the district court’s damages award without disputing the law
that the court applied. So we may assume (without deciding) that the court properly determined
that the correct measure of damages was the cost of restoring Mud Island to its prior condition.
The Baltimore, 75 U.S. 377, 385 (1869). And we may assume (without deciding) that Riverfront
needed only to prove this restoration cost “to a ‘reasonable degree of certainty.’” Nat’l Steel Corp.
v. Great Lakes Towing Co., 574 F.2d 339, 342 (6th Cir. 1978) (quoting Cranston Print Works Co.
v. Pub. Serv. Co. of N.C., 291 F.2d 638, 649 (4th Cir. 1961)).
Instead, Wepfer challenges the district court’s factual findings. We review “findings of
fact following a bench trial in an admiralty case for clear error, construing the evidence in the light
most favorable to the appellee.” F.C. Wheat Maritime Corp. v. United States, 663 F.3d 714, 723
(4th Cir. 2011); ConAgra, Inc. v. Inland River Towing Co., 252 F.3d 979, 983 (8th Cir. 2001). We
must affirm the findings if they are “plausible in light of the entire record,” even if we might have
“weighed the evidence differently.” Harlamert v. World Finer Foods, Inc., 489 F.3d 767, 771 (6th
8 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
Cir. 2007) (citing Anderson v. City of Bessemer City, 470 U.S. 564, 574–75 (1985)); Fed. R. Civ.
P. 52(a)(6). And we may reverse only if we are “left with the definite and firm conviction that a
mistake has been made[.]” Pearce v. United States, 261 F.3d 643, 647 (6th Cir. 2001) (quoting
Graves v. United States, 872 F.2d 133, 136 (6th Cir. 1989)).
Wepfer alleges four factual errors. It argues that the district court: (1) wrongly estimated
the size of the holes in Mud Island; (2) mistakenly found a need to excavate the sediment out of
the holes; (3) miscalculated the amount of sediment needed to be excavated; and (4) chose the
wrong fill material. The deferential standard of review requires us to reject all but the third
argument. We find that the district court committed clear error in calculating the amount of
sediment to excavate. Wepfer also challenges the district court’s denial of its Rule 59(e) motion,
but it makes no separate argument on the merits. So our resolution of these four main issues
suffices to resolve that issue.
1. Size of Holes. Wepfer first argues that the district court erred in crediting Reeder’s
measurements of the size of the holes in November 2016. To recap, the district court accepted
Reeder’s measurements that, as of November 2016, the holes were “roughly 10,000 cubic yards”
in size. And it accepted Reeder’s 20-percent “contingency” for additional material necessary to
compact the holes to the final grade.
The district court’s reliance on Reeder’s measurements for the holes’ initial size suffices
to survive the clear-error standard. Reeder has a degree in engineering. Using basic tools, he took
the holes’ average widths, lengths, and depths, and calculated a volume of 10,000 or so cubic
yards. He also explained the need for a 20-percent compaction contingency when refilling the
holes. He testified that, in his judgment, the measurements were “reasonably accurate.” The
9 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
evidence sufficed to prove the size of the holes to “a reasonable degree of certainty.” Nat’l Steel
Corp., 574 F.2d at 343.
Wepfer’s contrary arguments ask us to reweigh the evidence and reach a contrary
conclusion. That is not our job on appeal. See Harlamert, 489 F.3d at 771. Wepfer argues that
Reeder simply “ballparked” his estimate of about 10,000 cubic yards, using unsophisticated tools
and calculations. Wepfer contrasts Reeder’s approach with Ollar’s measurements, which used
standard surveying techniques to reach a much lower estimate of 2,972 cubic yards. And Wepfer
points to evidence suggesting that it was unlikely that the holes had filled with nearly 7,000 cubic
yards of sediment between the two measurements. Yet, invoking Tennessee law for this admiralty
case, Wepfer concedes that Riverfront needed only to present “substantial evidence” to allow the
district court to make a “fair and reasonable assessment of the amount of damages.” Apt. Br. 19
(quoting Grantham & Mann, Inc. v. Am. Safety Prods., Inc., 831 F.2d 596, 602 (6th Cir. 1987)).
Reeder’s measurements meet that substantial-evidence requirement. While we might not have
taken the same view of the facts, we cannot say the district court’s finding was clearly erroneous.
2. Need for Excavation. Wepfer next argues that the district court erred in crediting the
testimony from Riverfront’s witnesses that accumulated sediment must be excavated to restore
Mud Island to its original condition. There was no clear error. To begin with, both parties’
witnesses agreed that Mud Island is largely made of dredged sand. And Riverfront presented
uncontradicted evidence that river muck is not a suitable replacement for sand. So the parties
disputed only whether the sediment accumulating in the holes was sand (suitable) or muck (not
suitable).
Riverfront presented enough evidence for the court to find that the holes were mostly filling
with muck, not sand. Dr. Willson opined as to this fact and gave a reasoned explanation why—
10 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
because the Wolf River Harbor was mostly filled with muck and the holes were on the harbor side.
His expert opinion, rooted in his understanding of river dynamics, comported with Lendermon’s
practical experience. In Lendermon’s experience from other projects, the material in the mouth of
the Wolf River Harbor is “unsuitable” muck. The district court could rationally credit Dr.
Willson’s explanation as “persuasive” and could rationally conclude that Lendermon’s testimony
lent “further credibility” to those expert views. We treat these credibility findings with great
deference. See Fed. R. Civ. P. 52(a)(6); Madden v. Chattanooga City Wide Serv. Dep’t, 549 F.3d
666, 674 (6th Cir. 2008). The district court thus had “sufficient” evidence to make a “just and
reasonable” determination that the holes required excavation before refilling. Nat’l Steel Corp.,
574 F.2d at 342.
Wepfer’s counterarguments lack merit. It argues that the district court’s ruling was
improperly speculative because Riverfront never tested the sediment. To be sure, Dr. Willson and
Lendermon admitted that they did not know the holes’ contents with absolute certainty. But their
opinions were far from “speculation or guesswork.” See id. They were rooted in understanding
of, and experience with, the Mississippi River. As Lendermon explained, there were two ways to
determine the makeup of the accumulated sediment: to test it or to know “how it got there.” While
the first approach would provide greater clarity, the second approach, on this record, was sufficient
for the district court to reach a reasonably certain conclusion. Cf. ConAgra, 252 F.3d at 985.
Wepfer next points to contrary evidence. It cites Dr. Morris’s opinion, for example. But
“when a trial judge’s finding is based on [the] decision to credit the testimony of one or two or
more witnesses, each of whom has told a coherent and facially plausible story that is not
contradicted by extrinsic evidence, that finding, if not internally inconsistent, can virtually never
be clear error.” Madden, 549 F.3d at 674 (quoting Anderson, 470 U.S. at 575). Wepfer also cites
11 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
the observation from Ollar’s surveyor (Swink) that the holes contained material like the
undamaged portions of Mud Island. As the district court elsewhere found, however, “collapse of
other parts of the island” could account for some of the material in the holes. The court’s
excavation finding was not clearly erroneous.
3. Amount of Excavation. Wepfer argues that the district court erred in its calculation of
the volume of sediment to be excavated. It has a point. Recall that Reeder measured the size of
the holes as 10,000 or 10,100 cubic yards, but added a 20-percent “contingency” to account for
the extra fill material that Riverfront would need to compact the holes to grade level. When
Riverfront sought a quote for refilling the holes, it used this 12,000-cubic-yard figure. It also used
that same enhanced figure (12,000, not 10,000) when later seeking a quote for removing the
accumulated sediment from the holes. It asked Luhr Brothers to price out the excavation of 9,208
cubic yards of sediment. Riverfront reached the 9,208-cubic-yard figure by taking the difference
between Reeder’s enhanced estimate (12,000 cubic yards) and Ollar’s later measurement (2,792
cubic yards). And the district court awarded Riverfront $623,990, the cost of removing 9,208
cubic yards of material. The court clearly erred in calculating the amount to be excavated as 9,208
cubic yards.
The error comes from accepting the 12,000 cubic yards as the baseline size of the holes for
excavation purposes, when that figure included roughly 1,900 to 2,000 extra cubic yards of
material for filling purposes. By Reeder’s own telling, the compaction contingency for filling a
hole represents “more material than what the volume of the hole indicates[.]” He later repeated
this explanation, saying that “when you fill up holes, you have material that’s not compacted and
you have to buy more material than what is the volume of the hole.” So using the compaction-
enhanced volume for excavation overestimates the actual size of the holes, which were only 10,000
12 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
or so cubic yards by Reeder’s own telling. Reeder himself seemed to concede during cross-
examination that the compaction number should not be used to calculate the excavation number.
When Wepfer’s attorney asked him to explain why “the 20 percent compaction figure” should be
used to calculate the excavation amount, Reeder replied: “I didn’t say it would.” And Riverfront
has identified no other evidence supporting the use of this 12,000-cubic-yard figure for excavation
purposes. Given Reeder’s own explanation and the lack of other evidence, we have a “definite
and firm conviction that a mistake has been made” on this calculation. Pearce, 261 F.3d at 647
(quoting Graves, 872 F.2d at 136).
The true excavation volume likely should have been about 7,208 cubic yards (the “roughly
10,000 cubic yards” found by the district court, less 2,792). Ollar’s estimate included $60,000 in
fixed costs, plus variable costs based on excavation volume, with a multiplier of $61.25. See
Exhibit 25. Plugging in the new volume results in a total excavation cost of $501,490, which
would reduce the damages award by roughly $122,500. Yet the district court did not precisely
identify the actual size of the hole that Reeder measured. The court described Reeder’s estimate
as “roughly 10,000 cubic yards” based on his testimony that “I believe the number was 10,000
cubic yards, 10,100 cubic yards.” We will leave it to the district court to recalculate the proper
number on remand without the use of any compaction contingency.
Riverfront makes no argument to justify the use of the larger 12,000-cubic-yard number.
It claims that Wepfer’s “arguments on this finding are tethered to its position that Mr. Reeder’s
volume measurements were incorrect.” Ape. Br. 29. Not so. Wepfer makes this argument
“without waiving its [separate] argument that Reeder’s volume estimate [was] so exaggerated as
to render it incredible[.]” Apt. Br. 29–30. One can fully accept that Reeder correctly calculated
the size of the hole as roughly 10,000 cubic yards in volume and also conclude that the 2,000 cubic
13 No. 19-6088, Riverfront Development, Inc., et al. v. Wepfer Marine, Inc.
yards in compaction volume should not be used to calculate the excavation volume. Riverfront
also portrays the 9,208-cubic-yards figure as “consistent with all [the district court’s] other
findings,” including “that the volume of the land gouged out measured 12,000 cubic yards.” Ape.
Br. 29–30. That is mistaken. The district court found that Reeder had calculated an actual volume
of “roughly 10,000 cubic yards,” and separately allowed the 20-percent “contingency for
compression of the material.” The district court gave no explanation as to why the contingency
should also apply to determine the amount of excavation needed, and we have found no evidence
in the record that would suggest the contingency should have carried over in this way.
4. Material to Use. The district court lastly did not clearly err in concluding that “sand
would be an appropriate material to refill the depressions.” Several witnesses testified that sand
would restore Mud Island to its original condition.
In response, Wepfer points to evidence suggesting both that limestone was an acceptable
(or even preferable) material and that it was cheaper. But Wepfer asserts no legal argument that
Riverfront had any admiralty-based duty to mitigate damages by picking that alternative. And the
district court could reasonably require the same material that was used to create Mud Island.
For these reasons, we reject all of Wepfer’s arguments save one. We hold that the district
court clearly erred when it calculated the excavation amount. We reverse the district court’s
judgment and remand for entry of an amended damages award consistent with this opinion.
