MEMORANDUM OPINION

Appellant Tenaris Bay City Inc. challenges the jury verdict in favor of 

appellees—a group of 30 property owners—on their negligence claims relating to 

the flooding of their homes during Hurricane Harvey.

1

In five issues on appeal, 

Tenaris argues: (1) there is legally- and factually-insufficient evidence to support 

the jury’s finding on causation; (2) the trial court erred by allowing appellees’ 

expert to testify regarding causation; (3) there is legally- and factually-insufficient

evidence to support the jury’s finding that the water at issue was “surface water,”

as opposed to “flood water”; (4) the trial court erred by refusing to include 

Tenaris’s requested proximate-cause and flood-water instructions; and (5) the trial 

court erred by striking Tenaris’s designation of a responsible third party. We 

affirm.

I. BACKGROUND

In August 2017, Hurricane Harvey hit Texas and caused significant damage 

and flooding to areas all over the state, including—as is relevant to this appeal—

Matagorda County. In October 2018, appellees filed suit against appellant Tenaris, 

Fluor Enterprises Inc., and Jones & Carter Inc., alleging that the drainage system

designed for and constructed by Tenaris was responsible for the flooding damage 

to their homes.

Tenaris was the owner and operator of a seamless-pipe manufacturing 

1 Appellees consist of the following individuals: Ricky Ellisor; Jose L. Avila; William 

Johnson; Elizabeth Johnson; Mattie Halbison, individually and as representative of the estate of 

James Halbison; Dorene Tabares, individually and as heir at law to Armando Tabares; Armando

Ford; and Kimberly Davis.

facility, which the appellees allege caused the flooding of their homes. The facility 

had previously been a sod farm, but before building its facility on the property, 

Tenaris hired Fluor, an international engineering firm, to design the site’s drainage 

plan in accordance with the applicable laws and regulations necessary for the 

effective displacement of water as runoff to the surrounding homes. Jones & Carter 

was hired by the Matagorda County Drainage District to detail any concerns of the 

drainage plan before issuing a permit. Against Fluor, appellees brought claims for 

negligence and gross negligence, in addition to a claim for negligence per se for 

violations of the Water Code; against Tenaris, appellees brought claims for 

negligence, gross negligence, negligence per se, and negligent nuisance.2

Tenaris designated Milberger as a responsible third party.3 Appellees filed a 

motion to strike the designation, arguing there was no evidence of any negligence 

attributable to Milberger. The trial court granted the motion to strike.

The case proceeded to trial with the remaining parties. The first phase was to 

address liability in which the parties agreed to divide the properties at issue into 

three geographic zones: Zone A, Zone B, and Zone C. The trial court granted a 

directed verdict in favor of Tenaris and Fluor on the appellees’ claims of gross 

negligence as to all zones. The jury, however, returned a verdict in favor of

appellees, finding Tenaris liable for negligence, negligent nuisance, and negligence 

per se violations of the Water Code for all three zones; the jury also found Fluor 

liable for negligence for Zone C. Fluor settled with appellees on the Zone-C claim.

2 Against Jones & Carter, appellees brought claims for negligence and gross negligence, 

but they settled with plaintiffs before trial began.

3 Milberger refers collectively to Milberger Turfgrass, LLC; Bryan M. Milberger Trust 

2-1-1994; Francis Wayne Milberger Trust 2-1-1994; and Arthur J. Milberger Trust 2-1-1994.

Arthur testified at trial that before the Tenaris facility was built, the land was a “turf farm”

owned by Milberger. The record reflects some individuals still referred to the area in which

Tenaris was located as the “Milberger Farm.”
4

Tenaris and appellees entered into a stipulated agreement that the damages 

for all three zones was $2,800,000, removing the need for a trial on damages.

Tenaris filed a motion for judgment notwithstanding the verdict to disregard the 

jury’s findings and requested a new trial on the basis that the evidence was 

insufficient to support the jury’s findings. Tenaris argued that the plaintiffs did not 

establish sufficient evidence to prove the substantial-factor element for proximate 

causation. In a related argument, Tenaris asserted that the trial court erred in 

permitting appellees’ expert to testify regarding Zone C when the expert was 

previously on record admitting that he had not done the proper analysis to form 

opinions regarding that geographic zone. Further, Tenaris argued that it owed no 

duty to appellees because the water outflowing from Tenaris’s property was “flood 

water,” as opposed to “surface water,” and only the State of Texas has a duty to 

control flood water.

Alternatively, Tenaris argued that if there was sufficient evidence to hold 

Tenaris liable, then there must have been sufficient evidence to support a finding 

of liability against Milberger, as well. Accordingly, Tenaris argued that the trial 

court erred by striking their designation of a responsible third party.

However, because the trial court never ruled on Tenaris’s motion for 

judgment notwithstanding the verdict, it was denied as an operation of law. See

Tex. R. Civ. P. 329b(c).

II. ANALYSIS

A. Legal and factual sufficiency of proximate causation

In its first issue, Tenaris argues that the evidence was legally and factually 

insufficient to support the jury’s proximate-cause finding.

1. Standard of review and applicable law
5

When reviewing the legal sufficiency of the evidence, we consider the

evidence in the light most favorable to the challenged finding and indulge every 

reasonable inference that would support it. City of Keller v. Wilson, 168 S.W.3d 

802, 821–22, 827 (Tex. 2005); see also Graham Cent. Station, Inc. v. Peña, 442 

S.W.3d 261, 263 (Tex. 2014) (per curiam). The evidence is legally sufficient if it 

would enable a reasonable and fair-minded person to reach the verdict under 

review. City of Keller, 168 S.W.3d at 827. “If the evidence at trial would enable 

reasonable and fair-minded people to differ in their conclusions, then jurors must 

be allowed to do so.” Id. at 822. “A reviewing court cannot substitute its judgment 

for that of the trier-of-fact, so long as the evidence falls within this zone of 

reasonable disagreement.” Id.

We apply this standard mindful that this court is not a factfinder. See Turner 

v. Ewing, 625 S.W.3d 510, 518 (Tex. App.—Houston [14th Dist.] 2020, no pet.) 

(citing Maritime Overseas Corp. v. Ellis, 971 S.W.2d 402, 407 (Tex. 1998)). The 

factfinder is the sole judge of the witnesses’ credibility and the weight afforded 

their testimony. Turner, 625 S.W.3d at 518. “Generally, lay testimony establishing 

a sequence of events which provides a strong, logically traceable connection 

between the event and the condition is sufficient proof of causation.” Morgan v. 

Compugraphic Corp., 675 S.W.2d 729, 733 (Tex. 1984). But expert testimony 

related to causation is required when an issue involves matters beyond jurors’

common understanding. See Mack Trucks, Inc. v. Tamez, 206 S.W.3d 572, 583 

(Tex. 2006).

To prevail on a negligence claim, a plaintiff must prove the existence of: 

(1) a legal duty; (2) a breach of that duty; (3) proximate causation; and 

(4) damages. See Crosstex N. Tex. Pipeline, L.P. v. Gardiner, 505 S.W.3d 580, 607 

(Tex. 2016). Proximate causation incorporates two sub-elements: cause-in-fact (or 
6

“substantial factor”) and foreseeability. See Transcontinental Ins. Co. v. Crump, 

330 S.W.3d 211, 222 (Tex. 2010). “Cause in fact is established when the act or 

omission was a substantial factor in bringing about the injuries, and without it, the 

harm would not have occurred.” Id. at 222–23.

Foreseeability, the other element of proximate cause, requires that a person 

of ordinary intelligence should have anticipated the danger created by a negligent 

act or omission. See Doe v. Boys Clubs of Greater Dallas, Inc., 907 S.W.2d 472, 

478 (Tex. 1995).

2. Application

To determine whether the jury’s finding on proximate causation was 

supported by legally-sufficient evidence, we start by considering the evidence in

the light most favorable to the verdict and indulge every reasonable inference that 

would support finding proximate causation. City of Keller, 168 S.W.3d at 821–22.

At trial, appellees called Gabriel Novak—a civil engineer—as an expert to 

testify regarding Tenaris’s water drainage system and to his opinion regarding

what caused appellees’ homes to flood. According to Novak, Tenaris’s water 

drainage system was designed to temporarily hold storm water until it could be 

safely released into the surrounding area; to accomplish that goal, the drainage 

system, as designed by Fluor, was supposed to consist of three general detention 

ponds and a 44-foot-high berm surrounding the perimeter of the detention ponds.

4

Novak and Tenaris’s own experts testified that the water-drainage system, as 

designed, would be sufficient to prevent the volume of water generated by a

hundred-year storm from escaping Tenaris’s property and flooding appellees’

4 A “berm” is a “narrow shelf, path, or ledge typically at the top or bottom of a slope”; a 

berm can also be “a mound or wall of earth or sand.” See Merriam-Webster,

https://www.merriam-webster.com/dictionary/berm (last visited Jun. 23, 2023).

properties.5

However, Novak claimed that Tenaris’s water-drainage system failed to

meet the specifications in Fluor’s design plans. Relying on his on-site visit and 

pictures admitted at trial, Novak asserted that Tenaris’s berm wall was lower than 

44 feet in some areas and that the berm had holes in it at an elevation of 43 feet. 

Based on his calculations and the model testing he performed, Novak testified that

that once the storm water reached the water-surface elevation of the holes, the

storm water would flow through the holes into the surrounding area, causing 

flooding. Novak opined that the berm, as built, would not and could not operate as 

designed.

Charles Kalkomey, an engineer for Matagorda County, testified that the 

Matagorda County Drainage District received multiple complaints regarding

drainage in the Tenaris facility area before the facility was even constructed.

Kalkomey reached out to Tenaris to address the drainage issues, but to the best of 

his knowledge, Tenaris never addressed those drainage issues.

Michael Pruett, one of the directors of the Drainage District, testified 

regarding flooding problems with the Tenaris facility: “[I]t was all on the 

engineering drawings, there w[ere] problems with that to start with. . . . I just know 

there’s problems with people getting flooded out there since that facility—when a 

million-plus square feet of building was placed on that place.” In addition, several 

of the appellees also testified that over the last seventy years, their homes had

never flooded—despite being hit by other severe storms—before the Tenaris 

5 A “hundred-year storm” was defined at trial as an excess of 13.55 inches of rain falling 

in a 24-hour period. Lee Branscombe, a hurricane expert, testified that the Bay City and Van 

Vleck areas, the cities where appellees live, only received approximately 21.6 inches of rain 

during a four-day period. Thus, Branscombe opined that specifically as it affected Matagorda 

County, Hurricane Harvey would be classified a twenty-year storm.
8

facility was constructed.

Tenaris, through its own experts, provided evidence and testimony that its 

facility exceeded Fluor’s design plans in some respects; for example, Tenaris 

claimed that the berm was higher than 44 feet in some areas. Johnathan Johnson, 

Tenaris’s maintenance manager, testified that he was on-site, driving along the 

berm, during the storm; Johnson testified that he never saw storm water 

overflowing from the facility. He further claimed that if water had overflowed 

from the detention ponds, his office and the visitor center would have flooded, but 

they never flooded.

Tenaris’s engineering expert Jill Trevino testified that according to her 

reviews of the “as-built” drawings of the facilities, the berm was built according to 

design specifications and contained no holes. Thus, she opined that Tenaris did not 

cause the flooding because no storm water would have escaped the Tenaris facility.

However, she performed no modeling, mapping, or surveying of the area.

On appeal, Tenaris’s legal sufficiency challenge largely hinges on the 

following conversation that occurred between Tenaris’s counsel and Novak:

[Q]: Okay. But you haven’t, have you?

[A]: Done a detailed analysis of any of the specific plaintiff’s 

homes?

[Q]: Right.

[A]: No, I have not.

[Q]: In fact, you haven’t don[e] a general flooding analysis at 

all about what happened in Van Vleck, Texas, have you 

sir?

[A]: No, I have not.

[Q]: All you have looked at, sir, is to grade the papers of Fluor 

and Jones and Carter, right?
9

[A]: Yes.

[Q]: Okay. And so if the jury [is] going to be asked: Hey what 

caused these poor folks to have their homes flooded 

during Hurricane Harvey, you actually can’t answer that 

question, can you?

[A]: As far as to the specific homes?

[Q]: Yes, sir.

[A]: No, I cannot answer that question.

Thus, according to Tenaris, there is insufficient evidence on causation because 

appellees’ expert admitted that he could not opine on causation. However, during 

re-direct, when questioned by appellees’ counsel, Novak testified as follows:

[Q]: Mr. Novak, based on your education, work experience, 

and your modelling, have you — do you have an opinion

based on a reasonable degree of engineering probability 

whether or not the storm water drainage design plan as 

written by Fluor, and as implemented by Tenaris was a 

substantial factor in bringing about the flooding to 

plaintiffs’ properties?

[A]: My opinion is that the failure of the Fluor design and its 

implementation was a factor in the flooding of the 

plaintiffs’ properties.

It does not matter that Novak gave allegedly conflicting opinions on 

causation because it is the province of the jury to resolve conflicts in the evidence, 

and when reasonable jurors could resolve conflicting evidence either way, we 

presume they did so in accordance with the verdict. See City of Keller, 168 S.W.3d 

at 820. Even though Novak stated he could not opine on causation as to each of

appellees’ specific homes, he later testified that Tenaris’s failure to implement 

Fluor’s design plans was a substantial factor in the flooding of appellees’

properties.
10

In its supplemental briefing, Tenaris argues that this was a case that required 

expert testimony on causation because it involved complex issues beyond the 

jurors’ common understanding.

6 See Mack Trucks, 206 S.W.3d at 583. Thus, 

Tenaris asserts the evidence is legally insufficient because appellees’ expert did not 

specifically testify regarding substantial causation. In analyzing this argument, we 

find it helpful to imagine cases involving experts on a spectrum. On one end of the 

spectrum are cases in which an expert is always required. See, e.g., Tex. Civ. Prac. 

& Rem. Code Ann. § 74.351 (requiring expert report in health-care-liability 

claims). On the other end of the spectrum would be cases in which experts are 

almost never required; for example, a party would not need an expert to testify 

regarding causation in a simple slip-and-fall tort case. In the middle of the 

spectrum, are cases that might or might not require an expert, depending on the 

complexity of the case.

Although not binding, we note that our sister court has concluded that 

flooding causation tends to fall in the middle of the spectrum: “Regardless of 

whether an expert is required to testify specifically about the natural flow of 

surface water based on measurements of elevation, it is not always necessary to 

have expert testimony to establish flooding and its causes.” Michaelski v. Wright,

444 S.W.3d 83, 95 (Tex. App.—Houston [1st Dist.] 2014, no pet.). We must then 

determine if the present case was complex enough to require an expert, and we 

disagree with Tenaris’s assertion that the current case involves complex facts and 

issues beyond the jurors’ common understanding.

This case is unlike the many others in which expert testimony was held to be 

6 We note that in determining the alleged complexity of the case and its issues, knowing 

the distance between Tenaris and appellees’ homes might have been helpful. However, the

distance between Tenaris and the appellees’ homes is unclear from the record and the appellate 

briefs, and Tenaris does not otherwise indicate precise proximity.

required. See, e.g. ̧ Alexander v. Turtur & Assocs., Inc., 146 S.W.3d 113, 119 (Tex. 

2004) (concluding that expert testimony on causation is generally required in legal 

malpractice cases because “the wisdom and consequences of these kinds of tactical 

choices made during litigation are generally matters beyond the ken of most 

jurors”); Ins. Co. of N. Am. v. Myers, 411 S.W.2d 710, 713 (Tex. 1966) (holding 

that, when coupled with insufficient expert testimony, lay testimony and factual 

circumstances did not establish that injury aggravated existing cancerous tumor); 

Rayner v. Claxton, 659 S.W.3d 223, 255 (Tex. App.—El Paso 2022, no pet.) (“The 

physics involved in determining the distance at which it would take a truck at that 

weight to stop, combined with the mechanical knowledge about the brakes’ 

functionality and the effects of the braking violations noted by the officers, are not 

matters within ‘a layperson’s general experience and common understanding’

where lay testimony can provide adequate proof of causation.”); Pilgrim’s Pride 

Corp. v. Smoak, 134 S.W.3d 880, 894 (Tex. App.—Texarkana 2004, pet. denied)

(observing that chemical exposure cases generally require expert testimony on 

causation because “medically complex diseases and causal ambiguities compound

the need for expert testimony”); Coastal Tankships, U.S.A., Inc. v. Anderson, 87 

S.W.3d 591, 603 (Tex. App.—Houston [1st Dist.] 2002, pet. denied) (holding 

expert testimony required because decedent contracted bronchiolitis obliterans 

organizing pneumonia (BOOP), which has “several possible causes and is 

idiopathic a third of the time”).

Just because expert testimony might be helpful or available does not mean 

that it is necessary. While it might be beyond the common understanding of jurors 

to comprehend the natural flow of water or the engineering behind the 

storm-drainage system, it is within their understanding to reason that if Tenaris’s 

facility overflowed, it would cause flooding on nearby properties. Stated 
12

differently, the combined lay testimony and evidence in this case was sufficient to 

establish a sequence of events which provides a strong, logically traceable 

connection between Tenaris’s negligence and the flooding of appellees’ properties. 

Morgan, 675 S.W.2d at 733. It is also worth noting that Tenaris does not point us 

to any part of the record where it notified the trial court of its contention that expert 

testimony was specifically required on causation.

Ultimately, the jury heard conflicting evidence regarding causation, and it 

reasonably could have believed Novak’s testimony over Tenaris’s experts. See 

Gunn v. McCoy, 554 S.W.3d 645, 665 (Tex. 2018) (agreeing with court of appeals 

that legally-sufficient evidence existed to support finding of proximate cause when 

jury was presented with conflicting testimony from various experts). Viewed in the 

light most favorable to the appellees, we hold there was legally sufficient evidence 

to support the jurors’ finding that Tenaris was a substantial factor in bringing about 

appellees’ harm.

Regarding foreseeability, Tenaris argues that Hurricane Harvey was an act 

of God, and thus, inherently unforeseeable. However, even though Hurricane 

Harvey itself was not foreseeable, it is perfectly foreseeable that a negligently built 

storm-drainage system will cause flooding issues in nearby properties. This is 

especially true when flooding was a known issue in the area of the Tenaris facility, 

even before the facility was constructed. Thus, we conclude there was 

legally-sufficient evidence of foreseeability. Doe, 907 S.W.2d at 478.

Regarding factual sufficiency, we cannot conclude that the jury’s finding is 

so against the great weight and preponderance of the evidence as to be manifestly 

unjust. Golden Eagle Archery, Inc. v. Jackson, 116 S.W.3d 757, 773 (Tex. 2003). 

As detailed above, the jury was presented evidence from multiple experts 

regarding causation. The jury also heard testimony from multiple homeowners in 
13

the area, all testifying that their homes had never flooded during prior hurricanes;

their homes only flooded once the Tenaris facility was constructed. Accordingly, 

we conclude that the evidence was legally sufficient to support the jury’s finding

and not factually insufficient as to require a new trial.

We overrule issue 1.

B. Exclusion of expert testimony

In issue 2, Tenaris argues that the trial court should have excluded Novak’s 

testimony regarding Zone C because in his original deposition, he acknowledged

that he had not performed a specific analysis for the Zone-C properties. Thus, 

Tenaris claims that his testimony should have been excluded as an undisclosed 

expert opinion. However, we find the cases that Tenaris relies on to be

unpersuasive.

A trial court’s admission or exclusion of expert testimony is reviewed for an 

abuse of discretion. Gunn, 554 S.W.3d at 666. A trial court abuses its discretion by 

failing to follow guiding rules and principles. Id. To reverse a trial court’s 

judgment based on the exclusion of evidence, we must conclude that the trial court 

did in fact commit error and the error was harmful. Id. (citing Gee v. Liberty Mut. 

Fire Ins. Co., 765 S.W.2d 394, 396 (Tex. 1989)).

A party’s duty to supplement written discovery regarding a testifying expert 

is governed by Texas Rule of Civil Procedure 193.5. Tex. R. Civ. P. 193.5. Under 

that rule, the duty to supplement or amend arises when a party learns that its 

previous responses to written discovery were incomplete or inaccurate when made 

or are no longer complete or correct. Tex. R. Civ. P. 193.5(a). Courts have held

that “[a] last minute, material alteration in the expert’s testimony is just as 

damaging as the complete failure to list an expert.” Collins v. Collins, 904 S.W.2d 
14

792, 801 (Tex. App.—Houston [1st Dist.] 1995), writ denied per curiam, 923 

S.W.2d 569 (Tex. 1996) (emphasis added).

Tenaris cites to cases such as Beinar v. Deegan for the proposition that 

expert testimony at trial that materially varies from pre-trial disclosures should be 

excluded. Beinar, 432 S.W.3d 398, 404 (Tex. App.—Dallas 2014, no pet.). And 

while Beinar is not controlling on our court, it is also distinguishable from the 

present case. In Beinar, the suit involved damages to the plaintiff’s home allegedly 

caused by defendants’ landscaping renovations. Id. The plaintiff’s expert initially

concluded that “the foundation movement and deflections measures is not of a 

large magnitude at this time” and was considered “typical for a home of this age 

and construction.” Id. at 403. He also originally disclosed that “[n]o foundation 

repairs or adjustments are needed.” Id. But approximately one year later, the expert

noted new tension cracks he attributed to the defendants’ renovations, and he stated 

such renovations caused, and will cause in the future, damage to the plaintiff’s 

foundation. Id. at 403–04. The court of appeals concluded that the trial court did 

not err in excluding the expert’s opinion because the expert materially altered his 

opinion. See id. at 404–05.

By contrast, in the present case, Novak never materially altered his opinion.

According to appellees’ original expert designation:

Mr. Novak will opine on the acceptable standards and practice of

storm water management flood controls management in the State of 

Texas. He will testify that the Hurricane Harvey event as it occurred 

in Van Vleck and surrounding area was not an act of God, because the 

amount of rainfall that fell in the area was not unprecedented or

extraordinary and, in fact, was foreseeable. Mr. Novak will opine that 

Plaintiff’s properties were damaged due to rainfall runoff, from the

Tenaris Bay City facility. Further, Mr. Novak will testify that the Bay 

City facility’s internal drainage and storage system were inadequate, 

that the hydro—hydrologic study and hydraulic analysis of the facility 
15

was inadequate, that the hydraulic—and hydraulic modeling approach 

used in the design and analysis of the internal drainage system was 

inadequate and not property developed. And that these acts, errors, 

and omissions previously listed, failed to meet the applicable 

standards and resulted in the flooding of plaintiff’s homes and 

properties.

Novak was always of the opinion that the flooding of appellees’ properties was 

caused by Tenaris and that opinion never materially changed. We conclude that the 

trial court did not err in refusing to exclude Novak’s testimony. Tex. R. Civ. P.

193.5(a).

7

We overrule issue 2.

C. Surface water

In issue 3, Tenaris argues there was legally- and factually-insufficient 

evidence that surface water flooded appellees’ homes.

1. Standard of review and applicable law

“No person may divert or impound the natural flow of surface waters in this 

state, or permit a diversion or impounding by him to continue, in a manner that 

damages the property of another by the overflow of the water diverted or 

impounded.” Tex. Water Code Ann. § 11.086(a).

“[S]urface water” is simply water or natural precipitation diffused 

over the surface of the ground until it either evaporates, is absorbed by 

the land, or reaches a bed or channel in which it is accustomed to 

flow. Consequently, a distinguishing feature of “surface water” is that 

it is never found in a natural watercourse. A “watercourse” has been 

judicially defined as having (1) a bank and bed, (2) a current of water, 

and (3) a permanent source of supply.

7

In a related argument, Tenaris asserts that it was entitled to a new trial because once 

Novak’s testimony is excluded, there is no evidence regarding causation regarding Zone C 

properties. Because we conclude that Novak’s testimony was properly admitted, we do not need 

to address this argument. Tex. R. App. P. 47.1.
16

Dietrich v. Goodman, 123 S.W.3d 413, 418 (Tex. App.—Houston [14th Dist.] 

2003, no pet.) (internal citations omitted). Stated differently, the chief 

characteristic of surface water is that it “does not follow a defined course or 

channel and does not gather into or form a natural body of water.” Id. at 419.

Where rain water is under control by a ditch, tank, pond, or pipe, it no longer 

qualifies as surface water. Id.

“In contrast, floodwaters are those which, generally speaking, have 

overflowed a river, stream or natural water course and have formed a continuous 

body with the water flowing in the ordinary channel.” Texas Woman’s Univ. v. 

Methodist Hosp., 221 S.W.3d 267, 278 (Tex. App.—Houston [1st Dist.] 2006, no 

pet.) (internal citations omitted). The State has the ownership of, and the 

nondelegable duty to control, floodwaters; thus, if the water that flooded appellees’

property is categorized as floodwaters, Tenaris had no legal duty. See id.

2. Application

Tenaris argues that while the evidence at trial established that rainwater on 

Tenaris’s property could initially be categorized as surface water, it necessarily 

must have passed through a natural watercourse before reaching appellees’

properties, and thus the surface water was converted to floodwater. We disagree 

with Tenaris because the relevant inquiry is whether it was surface water at the 

time of diversion.

Tenaris compares the present case to Dietrich, but we find it to be 

distinguishable. 123 S.W.3d at 418. In Dietrich, the plaintiff asserted claims of

negligence, trespass, and violation of Water Code section 11.086 against his 

neighbor who allegedly landscaped around and over a storm sewer on his property, 

occluding the storm drain and diverting water into the plaintiff's home on a

neighboring lot. Id. at 416–17. Before the water was diverted, it had been 
17

“concentrated and directed toward the drain by a shallow, but readily visible, 

natural gully, that extended sixty feet or more into the wooded area.” Id. at 419–20. 

We stated that, under the then-existing law, a plaintiff had no cause of action 

“stemming from the diversion of water contained in a natural watercourse.”

In other words, the crucial fact in Dietrich was that the surface water had 

already been travelling in a natural watercourse before the defendant diverted it. 

Our sister court summarized Dietrich’s conclusion as follows:

the holding of Dietrich is actually limited to the fact that, under 

section 11.086, a landowner has no cause of action for damages 

arising from the diversion of a water flowing in a watercourse (in that 

case, a natural gully) because such waters are no longer diffused 

surface waters. . . . In sum, nothing in section 11.086 suggests that 

accumulated rainfall is no longer diffused surface water once it has 

been, in any way, diverted by artificial means or touched by the hands 

of man.

Texas Woman’s Univ., 221 S.W.3d at 283. The analysis in Texas Woman’s 

University focused on the identity of the water at the time it was diverted—not the 

identity of the water when it flooded the plaintiff’s property. See id. at 279–83; see 

also Good River Farm, LP v. Martin Marietta Materials, Inc., No. 

1:17-CV-1117-RP, 2023 WL 2904577, at *4 (W.D. Tex. Apr. 11, 2023) (“Because 

[§ 11.086] contains no requirement that the water be entirely surface water when it 

reaches the plaintiff’s property, the Court will not read in such a requirement 

where none exists.”).

While there was some evidence presented at trial that the water that flooded 

appellees’ properties may have been at least partially categorized as floodwater by 

passing through a channel after being diverted by Tenaris but before flooding their 

properties, there was no evidence showing that the water was anything but surface 

water at the time Tenaris diverted it. Texas Woman’s Univ., 221 S.W.3d at 283.

Therefore, we conclude that the evidence was legally and factually sufficient to 

support the jury’s finding that Tenaris diverted surface water. City of Keller, 168 

S.W.3d at 827.

We overrule issue 3.

D. Jury charge instructions

In issue 4, Tenaris asserts the trial court erred by refusing to include 

Tenaris’s requested proximate-cause and flood-water instructions.

1. Standard of review and applicable law

Generally, the trial court has considerable discretion in determining the 

proper jury instructions, and we will only reverse if the trial court abused its 

discretion. See Columbia Rio Grande Healthcare, L.P. v. Hawley, 284 S.W.3d 851, 

856 (Tex. 2009). The trial court abuses its discretion if it acts arbitrarily or fails to

follow guiding rules and principles. See id.

According to Rule 277, the trial court should give “such instructions and 

definitions as shall be proper to enable the jury to render a verdict.” Tex. R. Civ. P.

277. An instruction is proper if it “(1) assists the jury, (2) accurately states the law, 

and (3) finds support in the pleadings and evidence.” Hawley, 284 S.W.3d at 856. 

But if a particular instruction would exaggerate, minimize, or withdraw from the 

jury’s consideration some pertinent evidence, then such instruction is improper. 

See Moody v. EMC Servs, Inc., 828 S.W.2d 237, 244 (Tex. App.—Houston [14th 

Dist.] 1992, writ denied). Thus, “a trial court may refuse to give the jury a 

requested instruction when the instruction is not necessary to enable the jury to 

render a proper verdict, even if the instruction represents a correct statement of 

law.” Haynes v. Union Pac. R.R., 598 S.W.3d 335, 348 (Tex. App.—Houston [1st 

Dist.] 2020, pet. dism’d).

For this reason, the supreme court has generally advised that a jury charge 
19

for a statutory cause of action should track the statutory language as closely as 

possible. See Regal Fin. Co. v. Tex Star Motors, Inc., 355 S.W.3d 595, 601 (Tex. 

2010) (“The language may be slightly altered to conform the issue to the evidence 

presented in the case, but a court should not burden a jury with surplus 

instructions.” (internal citation omitted)); Spencer v. Eagle Star Ins. Co. of Am., 

876 S.W.2d 154, 157 (Tex. 1994) (“[A] jury charge should track the language of 

the provision as closely as possible.”). “The omission of an instruction is reversible 

error only if the omission probably caused the rendition of an improper judgment.”

Shupe v. Lingafelter, 192 S.W.3d 577, 579 (Tex. 2006). Error in the omission of an 

issue is harmless “when the findings of the jury in answer to other issues are 

sufficient to support the judgment.” Id. at 579-80 (quoting Boatland of Houston,

Inc. v. Bailey, 609 S.W.2d 743, 750 (Tex. 1980)).

2. Application

a. Proximate-cause instruction

As relevant to this appeal, appellees sued Tenaris for common-law

negligence, negligent nuisance, and negligence per se for violating the Water 

Code. For the negligence and negligent-nuisance claims, the jury was instructed as 

follows concerning proximate causation:

With respect to the conduct of Tenaris Bay City, Inc. and Jones & 

Carter “proximate cause” means a cause, unbroken by any new and 

independent cause, that was a substantial factor in bringing about an 

injury, and without which cause such injury would not have occurred.

In order to be a proximate cause, the act or omission complained of 

must be such that a person using ordinary care would have foreseen 

that the injury, or some similar injury, might reasonably result 

therefrom. There may be more than one proximate cause of an injury, 

but if an act or omission of any person not a party to the suit was the 

“sole proximate cause” of an injury, then no act or omission of any 

party could have been a proximate cause.

Tenaris requested that the proximate-cause instruction also be given to the jury for 
20

the negligence-per-se claim for violating Water Code section 11.086, but the trial 

court denied Tenaris’s request; Tenaris objected to its omission.

In question 5 of the jury charge, concerning section 11.086, the jury was 

asked, “Did Tenaris divert or impound surface water in a manner that damaged 

Plaintiffs’ properties?” The trial court included the following instructions:

“Surface Water” means water which is diffused over the ground from 

falling rains or melting snows, and it continues to be such until it 

reaches some bed or channel in which water is accustomed to flow.

When rainfall is under control, either by ditches, tanks, ponds or 

pipes, it is no longer considered surface water.

The diversion or impounding of surface water, if any, must have 

caused damages to Plaintiffs’ properties and without which cause such 

injury would not have occurred.

The jury answered, “Yes.”

Tenaris claims that the trial court’s refusal to include an additional 

instruction in question 5 regarding proximate cause created a negative inference, 

such that the jury may have concluded that proximate cause was not part of the 

causation element of that theory of recovery. We note that the trial court’s 

language closely tracked the language of the statute and the language used in prior 

case law. See Texas Woman’s Univ., 221 S.W.3d at 283; Dietrich, 123 S.W.3d at

418. We also observe that Tenaris has not cited any case where the omission of 

such an instruction was found to be erroneous. The trial court did not err in 

refusing Tenaris’s additional requested instruction on proximate cause.

b. Water instruction

Tenaris also requested the following instruction regarding surface water and 

flood water:

Surface water is distinct from both (i) flood waters and (ii) waters 

entering or following a defined course or channel. Flood waters are 

waters that have overflowed a natural water course but remain a 
21

continuous part of that original part of the water course. Flood waters 

are not surface water.

While this represents an accurate statement of law, Tenaris has not demonstrated 

that such an instruction was necessary to enable the jury to render a proper verdict.

See Haynes, 598 S.W.3d at 348. The trial court properly instructed the jury 

regarding surface water and its definition; the trial court’s instructions were 

accurate and tracked the statute and case law. Given the trial court’s discretion on 

this matter, it may have concluded that an additional instruction on flood water 

may have burdened the jury with surplus instructions. See Regal Fin., 355 S.W.3d 

at 601. Furthermore, the trial court may have deemed the requested instruction as 

unnecessary because even though there was evidence that the water may have been 

categorized as flood water by the time it reached appellees’ properties, there was

no evidence that the water Tenaris diverted had overflowed a natural water course. 

Therefore, we conclude the trial court did not err in refusing Tenaris’s requested 

instruction on surface water and flood water.

We overrule issue 4.

E. Responsible third party

In issue 5, Tenaris asserts that the trial court erred by striking its designation 

of a responsible third party— Milberger Grass Farm.

1. Standard of review and applicable law

To obtain a jury submission on proportionate responsibility, Tenaris needed 

to establish the following: (1) a duty requiring Milberger to conform to a certain 

standard of care; (2) the applicable standard of care and its breach by Milberger; 

(3) resulting injury; and (4) a reasonably close causal connection between 

appellees’ injuries and Milberger’s negligence or breach of the standard of care. 

See Gunn v. McCoy, 489 S.W.3d 75, 95 (Tex. App.—Houston [14th Dist.] 2016), 

aff’d, 554 S.W.3d 645 (Tex. 2018); see also Tex. Civ. Prac. & Rem. Code Ann. 
22

§ 33.003(b) (stating that proportionate-responsibility statute “does not allow a 

submission to the jury of a question regarding conduct by any person without 

sufficient evidence to support the submission.”); Tex. Civ. Prac. & Rem. Code

Ann. § 33.004(l) (“After adequate time for discovery, a party may move to strike 

the designation of a responsible third party on the ground that there is no evidence

that the designated person is responsible for any portion of the claimant’s alleged 

injury or damage. The court shall grant the motion to strike unless a defendant

produces sufficient evidence to raise a genuine issue of fact regarding the 

designated person’s responsibility for the claimant’s injury or damage.”).

2. Application

Tenaris argues the trial court erred in striking its designation of Milberger as 

a responsible third party based solely on evidence from appellee Ellisor. In a video 

taken during Hurricane Harvey, Ellisor exclaimed that storm water coming out of 

Milberger had always been a problem, and Ellisor additionally described the water 

reaching his house as “running over the top of the road coming out of Milberger’s 

Grass Farm.”

There is no evidence in the record regarding Milberger’s duty or standard of 

care, or whether Milberger’s alleged breach of the applicable standard caused 

appellees’ injuries. Ellisor’s video only vaguely asserts that Milberger had been a 

problem in the past and that some water came from the direction of Milberger. This 

lone piece of evidence from a single appellee constitutes no more than a scintilla of 

evidence. See Tex. Civ. Prac. & Rem. Code Ann. § 33.003(b); see also In re 

Coppola, 535 S.W.3d 506, 508 (Tex. 2017) (concluding trial court may strike 

responsible third-party designation if there are insufficient facts concerning third 

party’s responsibility). Therefore, we conclude that the trial court did not err in 

striking Tenaris’s motion to designate a responsible third party. Gunn, 489 S.W.3d 
23

at 99 (concluding in medical malpractice case that defendants were not entitled to 

comparative responsibility instruction on nurses’ alleged negligence even though

expert testimony suggested nurses’ conduct was problematic).

We overrule issue 5.

III. CONCLUSION

We affirm the judgment of the trial court as challenged on appeal.
