MEMORANDUM OPINION

Before Justices Myers, Osborne, and Nowell

Opinion by Justice Nowell

The City of Dallas appeals from a judgment awarding Trinity East Energy, 

LLC (Trinity) damages for the regulatory taking of its rights to produce minerals 

under oil and gas leases within the City by failing to approve special use permits 

necessary to drill gas wells inside the City. Because the evidence is sufficient to 

support the trial court’s finding of a regulatory taking and the jury’s determination 

of the fair market value of the property taken, we affirm the trial court’s judgment 
–2–

on the regulatory taking claim. We need not address the remaining issues.1 TEX. R.

APP. P. 47.1.

Background

In 2007, after identifying potential sites for gas exploration, the City issued a 

request for proposals to lease several thousand acres owned by the City for gas well 

drilling and production. The request for proposals included City-owned property 

located on the western edge of the City and within the Barnett Shale area of play. 

Trinity successfully bid for two groups of properties, identified as the Group 1 and 

Group 2A properties. The trial court’s judgment for a regulatory taking applies only 

to the Group 1 Lease (hereinafter the “Lease”). 

The City designated a single tract as an available drill site location in the 

request for proposal. Trinity held several mineral leases near the area included in the 

City’s request for proposals. Trinity responded to the request for proposal and 

indicated it had over twenty drill sites on other acreage and estimated that 

approximately ninety percent of acreage included in the request for proposals was 

drillable from Trinity’s drill sites and the site offered by the City. Trinity’s response 

also stated that it was in the process of obtaining seismic information on the area and 

after analyzing that data planned to drill a science well to evaluate the entire Barnett 

1 Trinity sued the City on multiple causes of action. The trial court awarded judgment on the regulatory 

taking claim for the fair market value of the property as found by the jury and an alternative judgment based 

on the jury’s findings of liability and damages for statutory fraud and negligent misrepresentation in the 

event the regulatory taking judgment is reversed. The City brings ten issues on appeal, attacking both 

portions of the judgment.

Shale and underlying formations and the potential for the area. After analyzing the 

results of the data obtained, Trinity would design and implement a continuous 

drilling program using multiple drilling rigs. 

After winning the bid, Trinity performed comprehensive title work and 

determined the City owned an additional tract in the area, referred to as the Radio 

Tower tract. During negotiations for the final terms of the Lease, Trinity insisted that 

the Radio Tower tract be included in the Lease as a drill site location. Trinity 

determined that the units that could be formed from the Radio Tower tract were 

important acreage in Dallas and extending into Las Colinas and Irving. Trinity’s

former president, Steve Fort, described the area as the “heart of the play.” He 

explained that Trinity had difficulty obtaining drill sites in Las Colinas but the Radio 

Tower site would allow development in that area. Trinity also identified another 

tract, known as the Gun Club, as a drill site location. The City ultimately agreed to 

include the Radio Tower and Gun Club sites in the Lease, but only as proposed drill 

site locations. 

Trinity continued its seismic work and due diligence while negotiating the 

final terms of the Lease. In May 2008, Trinity drilled a science well near the 

University of Dallas to obtain detailed information about the prospect of producing 

natural gas from the property. Based on information obtained from the science well 

and seismic data, Trinity determined that the area contained a producible type of 

Barnett Shale, similar to Barnett Shale in other highly productive areas. Fort testified 
–4–

that the information from the science well confirmed that the City acreage was some 

of the best acreage in Trinity’s group of leases. 

Using the same well-bore as the science well, which was a vertical well, 

Trinity drilled a horizontal well to obtain production from the University of Dallas 

site. This well obtained gas production and a unit was formed around it. The unit 

included approximately 150 acres of land included in the Lease. Although the well 

produced some gas, it also produced significant amounts of water. The gas was also 

higher in carbon dioxide than allowed by Trinity’s contract with Atmos Energy, 

requiring the gas to be mixed with other gas to meet the specifications. The well lost 

money and was later abandoned. Trinity attempted to drill another horizontal well 

from the same location but it was lost due to defective casing.

The City’s drilling ordinance in effect at the time of the Lease required anyone 

desiring to drill an oil and gas well to obtain a special use permit (SUP) from the 

City. In addition, the lessee would be required to obtain several other permits or 

approvals before drilling and operating a well. Trinity’s members were experienced 

oil and gas producers and familiar with the process for obtaining the permits and 

approvals necessary to drill wells. They had successfully obtained SUPs from other 

cities, including Fort Worth, Farmers Branch, and Irving. There was evidence that 

from 2007 to 2010, the City approved five SUPs for gas drilling by other developers 

on private property. 
–5–

The City and Trinity signed the Lease in August 2008. Trinity paid the City a

lease bonus of over $19 million, a 25% royalty on gas, and an overriding royalty 

interest on gas produced from other leases through wells on City drill sites. The 

Lease covered over 2,000 acres and identified one tract as a drill site location and 

three other tracts as proposed drill site locations, including the Radio Tower and Gun 

Club sites.

2

On the same day the Lease was signed, Trinity and the City Manager signed 

an assurance letter stating that although City staff could make no guarantees, they 

were reasonably confident that Trinity would be granted the right to use the Radio 

Tower tract as a drill site and staff would use its reasonable efforts to assist Trinity 

in putting permits before the City Council and in obtaining other permits necessary 

to create a drill site and production facility on the Radio Tower tract. The letter 

acknowledged it was not a binding agreement but was a good faith representation of 

their discussions in connection with the transaction. 

Trinity began the process of preparing for drilling operations. It performed 

engineering, surveying, and other work necessary for producing the minerals, 

including the design of drill site pads, pipeline alignment, archaeological and tree 

surveying, and seeking regulatory approval from federal, state, and local authorities, 

such as the Railroad Commission, the Army Corps of Engineers, and the City. 

2 Approximately 600 acres were later removed from the Lease by an amendment that also extended the 

primary term of the Lease.
–6–

By 2010, Trinity was ready to obtain the necessary permits from the City. 

Around the same time, the City was considering updating its gas drilling ordinance. 

City staff told Trinity that its regulatory applications would face delays due to 

reductions in City staff and recommended delaying the applications until after the 

May 2011 elections due to political concerns. However, Trinity faced a deadline to 

commence operations under the Lease by August 2011 and submitted SUP 

applications in March for drill site locations on the Radio Tower and Gun Club sites 

and on a privately owned tract known as Luna South. The trial court found that the 

SUP applications were filed in accordance with applicable law. In July 2011, the 

City and Trinity agreed to extend the primary term of the Lease for an additional 

thirty months. 

City staff eventually recommended approval of the SUPs with several 

conditions. However, after Trinity submitted the applications, the City appointed a 

gas drilling task force to determine the future of gas drilling in the City, which 

resulted in a lengthy delay in considering the SUP applications. In December 2012, 

the City Planning Commission considered Trinity’s SUP applications and denied 

them. Afterwards, an attorney for the City contacted Trinity about finding alternative 

sites for drilling. Several sites were discussed, but none were feasible. One was 

underwater, the land owner would not agree to surface drilling on another, and others 

were too remote from the high quality Barnett Shale reserves under the leased 

acreage. 
–7–

Because the City Planning Commission denied the SUP applications, the City 

Code required a three-quarters vote of the City Council to overturn the planning 

commission decision. On August 28, 2013, the City Council voted on Trinity’s 

appeal of the denial of the SUPs. A majority of the council voted to approve the 

SUPs, but the vote was less than the required three-quarters margin. As a result, the 

SUPs were denied. In December 2013, the City amended the gas drilling ordinance 

and imposed strict setback and other restrictions that would essentially preclude 

drilling on the Lease or within the City limits. The Lease subsequently expired and 

the mineral interest reverted to the City.

Trinity sued the City on several causes of action. The case was tried to the 

court and a jury in a single proceeding. Trinity presented evidence at trial that the 

fair market value of Trinity’s leases that could be developed from the three drill sites 

was $26,580,000 to $40,698,000 before denial of the SUPs. It also presented 

evidence that after denial of the SUPs the property was worth nothing and the Lease 

expired. 

The jury failed to find that the City breached the Lease, but found the City 

committed statutory fraud and negligent misrepresentation and awarded damages. 

Over the City’s objection, the trial court submitted the question of the fair market 

value of Trinity’s property before and after denial of the SUPs to the jury. The jury 

found the fair market value of Trinity’s property before the denial of the SUPs was 

$33,639,000 and zero after the denial. The trial court determined that the City 
–8–

committed a regulatory taking by failing to approve the special use permits and 

awarded Trinity compensation in the amount of $33,639,000. The trial court signed 

findings of fact and conclusions of law in connection with its regulatory taking 

findings.

Standard of Review

In evaluating the legal sufficiency of the evidence to support a finding, we 

credit favorable evidence if a reasonable factfinder could, and disregard contrary 

evidence unless a reasonable factfinder could not. City of Keller v. Wilson, 168 

S.W.3d 802, 827 (Tex. 2005). Evidence is legally insufficient when (a) evidence of 

a vital fact is completely absent; (b) the court is barred by rules of law or of evidence 

from giving weight to the only evidence offered to prove a vital fact; (c) the evidence 

offered to prove a vital fact is no more than a mere scintilla; or (d) the evidence 

establishes conclusively the opposite of the vital fact. Id. at 810. Evidence is more 

than a scintilla if it “rises to a level that would enable reasonable and fair-minded 

people to differ in their conclusions.” Ford Motor Co. v. Ridgway, 135 S.W.3d 598, 

601 (Tex. 2004). However, evidence does not exceed a scintilla if it is so weak as 

to do no more than create a mere surmise or suspicion that the fact exists. Serv. 

Corp. Intern. v. Guerra, 348 S.W.3d 221, 228 (Tex. 2011).

In reviewing the factual sufficiency of the evidence, we review all the 

evidence and will set aside the finding only if the evidence is so weak or if the finding 

is so against the great weight and preponderance of the evidence that it is clearly 
–9–

wrong and unjust. Crosstex N. Tex. Pipeline, L.P. v. Gardiner, 505 S.W.3d 580, 615 

(Tex. 2016). “[T]he jury is the sole judge of the credibility of witnesses and the 

weight to be given their testimony.” Golden Eagle Archery, Inc., v. Jackson, 116 

S.W.3d 757, 761 (Tex. 2003). It is up to the jury “to resolve conflicts and 

inconsistencies in the testimony of any one witness as well as in the testimony of 

different witnesses.” Ford v. Panhandle & Santa Fe Ry. Co., 252 S.W.2d 561, 563 

(Tex. 1952).

Findings of fact made after a bench trial are of the same force and dignity as 

a jury’s verdict and appellate courts review them under the same sufficiency 

standards as applied in reviewing the evidence to support a jury’s verdict. See 

Catalina v. Blasdel, 881 S.W.2d 295, 297 (Tex. 1994); In re C.H.C., 392 S.W.3d 

347, 349–50 (Tex. App.—Dallas 2013, no pet.).

The Constitution of the State of Texas states, “No person’s property shall be 

taken, damaged, or destroyed for or applied to public use without adequate 

compensation being made, unless by the consent of such person.” Tex. Const. art. I, 

§ 17(a). The constitution waives governmental immunity for inverse condemnation 

claims. City of Dallas v. VSC, LLC, 347 S.W.3d 231, 236 (Tex. 2011). “Inverse 

condemnation is ‘a cause of action against a governmental defendant to recover the 

value of property which has been taken in fact by the governmental defendant, even 

though no formal exercise of the power of eminent domain has been attempted by 
–10–

the taking agency.’” Hearts Bluff Game Ranch, Inc. v. State, 381 S.W.3d 468, 476 

(Tex. 2012) (quoting United States v. Clarke, 445 U.S. 253, 257 (1980)).

To plead a claim for inverse condemnation, the claimant must allege an 

intentional government act that resulted in the uncompensated taking of his property. 

City of Houston v. Carlson, 451 S.W.3d 828, 831 (Tex. 2015). “A taking is the 

acquisition, damage, or destruction of property via physical or regulatory means.”

Id. “A regulatory taking is a condition of use ‘so onerous that its effect is tantamount 

to a direct appropriation or ouster.’” Id. (quoting Lingle v. Chevron U.S.A. Inc., 544 

U.S. 528, 537 (2005)).

Discussion

A. Regulatory Taking

In its first issue, the City contends that the evidence is legally and factually 

insufficient to support the trial court’s finding of a regulatory taking.

Texas law recognizes several theories under which a claimant may allege a 

regulatory taking, including (1) a Lucas claim, in which a property owner alleges 

that a property regulation denied the owner of all economically beneficial or 

productive use of the property, see Lucas v. S. Cent. Coastal Council, 505 U.S. 1003, 

1015–19 (1992); and (2) a Penn Central claim, in which a property owner alleges 

that, while a regulation did not deprive the owner of all economically viable use, the 

governmental action unreasonably interfered with the owner’s use and enjoyment of 

his property, see Penn Cent. Transp. Co. v. N.Y.C., 438 U.S. 104, 124 (1978)). See 
–11–

Edwards Aquifer Auth. v. Day, 369 S.W.3d 814, 838–39 (Tex. 2012); City of 

Sherman v. Wayne, 266 S.W.3d 34, 43–44 (Tex. App.—Dallas 2008, no pet.). The 

trial court’s findings of fact and conclusions of law support either theory. Because 

we conclude the evidence supports the trial court’s findings and conclusions on the 

Lucas theory, we do not discuss the Penn Central theory.

Under the Lucas theory, the question is whether the governmental regulation 

has deprived the owner of all economically viable use of his property. Mayhew v. 

Town of Sunnyvale, 964 S.W.2d 922, 935 (Tex. 1998). This requires determining 

whether any value remains in the property after the governmental action. Id.

The trial court found that other than the drill sites proposed in Trinity’s three 

SUP requests, “Trinity did not have reasonable access to other surface locations from 

which it could have economically accessed the minerals under lands covered by [the] 

Group I Lease or under Trinity’s private leases in the area of the property covered 

by the Group I Lease.” The jury found that the fair market value of Trinity’s property 

immediately after the City’s non-approval of the SUPs was zero. 

The City argues that denial of the SUPs did not deprive Trinity of all beneficial 

use of its property because there was evidence that Trinity had other drill sites from 

which it could have accessed at least some of the Lease acreage. The City also argues 

denial of the SUPs did not cause Trinity’s damages because Trinity had access to 

these alternative drill sites. However, there was evidence the factfinder could 
–12–

reasonably believe that none of the alternative drill sites were viable or feasible for 

economically developing Trinity’s mineral property. 

The City points to Trinity’s 2007 response to the request for proposals where 

Trinity represented it could drill ninety percent of the Group 1 Lease area from 

Trinity drill sites along with the one drill site offered in the request for proposals. 

But Trinity stated in the same response that it was in the process of obtaining seismic 

data and drilling a science well to evaluate the prospect and that after analyzing this 

data it would propose a continuous drilling plan. After its bid was accepted, Trinity 

obtained additional seismic data, drilled the University of Dallas science well, and 

determined the best way to maximize the value of its mineral interest was to use the 

Radio Tower, Gun Club, and Luna South tracts as drill site locations from which it 

could drill several horizontal wells to produce gas from several units formed around 

the drill sites. This was the reason Trinity insisted that the Radio Tower and Gun 

Club tracts be included in the final Lease and the City agreed to include them as 

proposed drill sites. Furthermore, the City’s petroleum engineer, Nick Steinsberger,

analyzed the drill site locations referenced in Trinity’s response to the request for 

proposals and testified that drilling from those drill sites would not have been 

productive or economic. 

Next, the City argues that Trinity could have drilled on tracts where it had 

SUPs from Irving and Farmers Branch and it drilled three wells from the University 

of Dallas site in Irving that accessed some of the Lease acreage. But the City fails to 
–13–

identify any evidence that these drill sites provided reasonable or economically 

viable access to all of Trinity’s minerals. See Mayhew, 964 S.W.2d at 935 (regulatory 

taking occurs where regulation denies owner all economically viable use of 

property); Tarrant Cty. Water Control & Improvement Dist. No. One v. Haupt, Inc., 

854 S.W.2d 909, 911, 913 (Tex. 1993) (Haupt II) (under accommodation doctrine 

alternative means of producing minerals must provide mineral lessee with 

reasonable access to mineral estate). The unit formed around the one production 

well on the University of Dallas site included about 150 acres of the over 1400 acres

in the Lease as amended. And, although the science well provided useful data to 

Trinity, the University of Dallas production well lost $11 million and was 

abandoned. 

Trinity’s geologist, Dennis Browning, testified that Trinity could not have 

used drill sites in Irving and Farmers Branch to drill a significant portion of the 

acreage included in the Lease. He explained that attempting to access that acreage 

from those sites would have required complex drilling and excessively long well 

bores. Trinity’s expert, Richard Strickland, a petroleum engineer, testified that 

Trinity could not have fully developed its mineral interests from drill sites in Farmers 

Branch and Irving. He explained those sites would require excessively long well 

bores to reach the minerals and maximize the value of the asset.

The City also contends Trinity could have sought SUPs for different sites.

Again, the City does not identify any evidence that Trinity would have been able to 
–14–

obtain SUPs from the City for other sites or that any other sites would have permitted 

Trinity to reasonably and economically develop its mineral property. See Haupt, Inc. 

v. Tarrant Cnty. Water Control & Imp. Dist. No. One, 870 S.W.2d 350, 355 (Tex. 

App.—Waco 1994, no writ) (Haupt III) (holding evidence factually insufficient to 

support deemed finding that alternative means of production by directional drilling 

or platform drilling over water provided reasonable access to mineral estate). 

Finally, the City argues Trinity was required to obtain regulatory approvals 

involving parkland and floodplain issues before it could drill. But there was evidence 

that Trinity was on track to obtain necessary approvals for drilling and could deal 

with the floodplain and parkland issues. Without the SUPs, however, Trinity could 

not drill at the three locations. And the City denied the SUP for Luna South, which 

was private property, not parkland, and not in the floodplain, which made it 

impossible for Trinity to drill from that location.

While the ultimate determination of whether there has been a regulatory 

taking is a question of law, we rely on the trial court to resolve factual disputes about 

whether the City’s denial of the SUPs deprived Trinity of all economically viable 

use of its property. See Mayhew, 964 S.W.2d at 932–33 (“While we depend on the 

district court to resolve disputed facts regarding the extent of governmental intrusion 

on the property, the ultimate determination of whether the facts are sufficient to 

constitute a taking is a question of law.”). The trial court resolved the factual disputes 
–15–

regarding the extent of the City’s regulation of drilling and the evidence supports its 

findings. 

We conclude the evidence is legally and factually sufficient to support the trial 

court’s finding that other than the three sites proposed in the SUPs, Trinity did not 

have reasonable access to other locations from which it could economically develop 

its mineral interests. Based on the evidence and the trial court’s findings we agree 

with the trial court that the City’s denial of the SUPs resulted in a regulatory taking 

of Trinity’s property. We overrule the City’s first issue.

B. Value Expert and Sufficiency

In its second and third issues, the City argues that Strickland’s testimony on 

market value was unreliable and therefore the evidence was insufficient to support 

the jury’s value findings. 

We review rulings on the admissibility of expert testimony for an abuse of 

discretion. Whirlpool Corp. v. Camacho, 298 S.W.3d 631, 638 (Tex. 2009). A party 

may also argue on appeal that an expert witness’s testimony is unreliable and 

therefore insufficient evidence to support a verdict. Id. A challenge to the sufficiency 

of the evidence is reviewed under traditional sufficiency standards. See City of 

Keller, 168 S.W.3d at 827; Crosstex N. Tex. Pipeline, L.P., 505 S.W.3d at 615.

An expert witness may testify regarding scientific, technical, or other 

specialized matters if the expert is qualified, the expert’s opinion is relevant, the 

opinion is reliable, and the opinion is based on a reliable foundation. See TEX. R.
–16–

EVID. 702; Mack Trucks, Inc. v. Tamez, 206 S.W.3d 572, 578 (Tex. 2006); Gammill 

v. Jack Williams Chevrolet, Inc., 972 S.W.2d 713, 726 (Tex. 1998). Expert testimony 

is unreliable “if there is too great an analytical gap between the data on which the 

expert relies and the opinion offered.” Volkswagen of Am., Inc. v. Ramirez, 159 

S.W.3d 897, 904–05 (citation omitted). Whether an analytical gap exists is largely 

determined by comparing the facts the expert relied on, the facts in the record, and 

the expert’s ultimate opinion. Gharda USA, Inc. v. Control Sols., Inc., 464 S.W.3d 

338, 348-49 (Tex. 2015). 

Courts rigorously examine the validity of the facts and assumptions on which 

expert testimony is based, as well as the principles, research, and methodology 

underlying the expert’s conclusions and the manner in which the principles and 

methodologies are applied by the expert to reach the conclusions. Whirlpool Corp., 

298 S.W.3d at 637. Trial courts act as gatekeepers, screening out irrelevant and 

unreliable expert opinions. See Gen. Motors Corp. v. Sanchez, 997 S.W.2d 584, 590 

(Tex. 1999) (noting “the trial court is the evidentiary gatekeeper with the primary 

responsibility to screen out unreliable expert evidence”). An expert’s “bald 

assurance” that they used an approved methodology is insufficient to show their 

opinion is reliable; the court must independently evaluate the underlying data in 

determining whether the opinion is reliable. Kraft, 77 S.W.3d at 808.

Strickland, a petroleum engineer specializing in reservoir engineering, 

testified he prepared a fair market value opinion on the acreage that could have been 
–17–

developed from the three drill sites on which Trinity requested SUPs from the City. 

He valued two separate development plans to drill those sites. The first plan, called 

Scenario A, called for 59 wells to develop six units containing approximately 2,800 

acres. The second plan, Scenario B, called for 29 wells to develop four units 

containing approximately 1,600 acres. Strickland opined on the fair market value of 

both scenarios using the comparable sales method and the discounted cash-flow 

method. He weighted the two methods at seventy-five percent for the comparable 

sales method and twenty-five percent for the discounted cash-flow method and 

arrived at a fair market value opinion for each scenario. Strickland then reduced that 

value to the acreage Trinity had under lease as of the date of the denial of the SUPs, 

August 28, 2013. Trinity had 51% of the acreage in Scenario A and 60% of the 

acreage in Scenario B under lease on that date. Strickland concluded the fair market 

value of Trinity’s owned leases under Scenario A was $40,698,000 and under 

Scenario B was $26,580,00 before the denial of the SUPs. Strickland’s opinion of 

the value of Trinity’s leases after the City denied the SUPs was zero. 

1. Proposed Units

The City argues that Strickland’s opinion is not reliable because he included 

acreage Trinity did not have under lease in the units he evaluated around each of the 

drill site locations and Trinity could not have leased all the acreage in Strickland’s 

proposed units. Strickland explained, however, that while he developed a value for 

units that could be produced from the drill sites, he also expressed a value opinion 
–18–

limited to only the acreage Trinity had under lease at the time of the City denied the 

SUPs. Because Strickland’s opinion identified the value of the acreage Trinity had 

under lease at the time of the taking, it is immaterial whether Trinity would have 

been able to lease additional land. Trinity sought only the fair market value of the 

acreage it had under lease at the time of the taking. There is no indication in the 

record that the jury was confused, as the City contends, because the proposed units 

included unleased acreage; the jury’s finding was within the range of the two 

scenarios involving only the acreage Trinity had under lease.

The City criticizes some of the units Strickland considered in his scenarios 

because they did not conform to the pooling provision of the Lease. Under the terms 

of the Lease, units formed around drill sites located on City land had to include 50% 

of their acreage from the City Lease. Units for sites not on City land required 20% 

of their acreage from the City Lease. However, the Lease provides that these 

minimum amounts could be decreased with the written consent of the City. Further, 

the Lease provides that if “there is insufficient unpooled acreage available from the 

Land to make up 20% of the unit (or 50% if applicable), then the remaining portion 

of the Land may be included in the unit.” 

Trinity presented evidence that lessors are motivated to consent to units if 

those units are necessary to develop the minerals because development results in 

royalties for the lessor. While a particular unit might contain less than the amount 

required in the pooling provision, Strickland’s proposed units collectively covered a 
–19–

significant portion of the acreage in the Lease as amended. Thus, the jury could 

reasonably conclude that the City would have provided consent to form the units 

rather than leave portions of the Lease unproductive. 

2. Comparable Sales

The City argues that the sales Strickland used in his comparable sales analysis 

were dissimilar to Trinity’s properties because Strickland used producing properties

while there was no production on Trinity’s leases and the sales were too far away 

from Trinity’s leases. 

Using public data and, in two cases, data from the seller, Strickland identified 

twenty-five Barnett Shale transactions from 2004 to 2013. Strickland had enough 

information from the public record to allow him to use six of those sales as 

comparable to Trinity’s leases. The six sales occurred from 2010 to 2013. Although 

he had more information about the two sales with data provided by the seller, he did 

not use those sales a comparables because they were from 2006 and 2008. Except 

for the 2006 sale, all of the sales he examined included both developed and 

undeveloped acreage. 

Using data from the six sales, he determined a value per acre for the 

undeveloped acres and made downward adjustments. He excluded two of the six 

sales because they were outliers, one very low and one very high. He then averaged 

the remaining four sales and applied a ten percent discount to account for the 

uncertainty in the City acreage. Strickland used that value and compared it to the 
–20–

two sales from 2006 and 2008 for which he had detailed information from the seller. 

One of those sales involved property that was completely undeveloped and he had 

information on the other of how the buyer and seller allocated the value between the 

developed and undeveloped acreage. He arrived at a value of $35,000 per acre. He 

used that value and calculated a net value for each of the two scenarios by subtracting 

leasing expenses and additional costs required for the City acreage that would not 

normally be included in comparable sales. 

The trial court has broad discretion in determining whether comparable sales 

are similar to the land being valued and its ruling is reviewed only for an abuse of 

discretion. Collin Cty. v. Hixon Family P’ship, Ltd., 365 S.W.3d 860, 868 (Tex. 

App.—Dallas 2012, pet. denied). Strickland used sales from the same time period as 

the taking and of the same type of asset, Barnett Shale acreage, as Trinity’s leases.

Although the six sales included both developed and undeveloped acreage, Strickland 

testified he extracted the undeveloped portion of the sales and used that in his 

evaluation. Strickland used only sales of Barnett Shale assets in his evaluation, 

explaining that the Barnett Shale is an unconventional reservoir and comparable 

sales need to be of a similar formation and similar characteristics.

The City argues that the sales were not in the vicinity of Trinity’s leases. 

Strickland located four of the comparable sales on a contour map of Barnett Shale 

thickness. He explained that the Barnett Shale is present over a very wide area and 

he considered Barnett Shale acreage across several counties. The sales, although 
–21–

located in Tarrant and surrounding counties, included acreage with similar thickness, 

three hundred to four hundred feet, as the Barnet Shale in the City acreage. We 

conclude that the distance of the comparable sales from Trinity’s leases was a 

consideration for the jury in weighing the evidence and the trial court did not abuse 

its discretion by admitting the evidence. See Hixon, 365 S.W.3d at 870 (stating the 

jury should consider all factors “which would reasonably be given weight in 

negotiations between a seller and a buyer”) (quoting City of Austin v. Cannizzo, 267 

S.W.2d 808, 815 (Tex. 1954)). Even so, comparable sales need not be in the 

immediate vicinity of the subject land, so long as they meet the similarity test. Id.

On this record, we conclude the trial court did not abuse its discretion by 

admitting the evidence of comparable sales. 

3. Discounted Cash Flow

The City contends that Strickland’s discounted cash-flow analysis was not 

reasonably certain. See Phillips v. Carlton Energy Group, LLC, 475 S.W.3d 265, 

279–80 (Tex. 2015) (holding lost profits cannot be recovered unless proven with 

reasonable certainty and this rule applies when lost profits are used to prove market 

value of property). 

When comparable sales are not available or inadequate as a measure of market 

value, other methods may be used to estimate fair market value. City of Harlingen 

v. Estate of Sharboneau, 48 S.W.3d 177, 183 (Tex. 2001). One method is the 

discounted cash-flow method or income approach. Id.; Maguire Oil Co. v. City of 
–22–

Houston, 69 S.W.3d 350, 363–64 (Tex. App.—Texarkana 2002, pet. denied)

(holding discounted cash-flow analysis provided some evidence of market value of 

leasehold in regulatory taking case involving revocation of permit to drill gas well). 

Strickland explained that the discounted cash-flow method uses the estimated future 

production, estimated future prices, and estimated costs of production to calculate 

the net income for the property. The net income is then discounted to present value. 

To estimate future production, Strickland identified existing wells analogous 

to the wells Trinity would be drilling. He looked at wells that were close in 

geography, near DFW airport, and in geology, near Lone Star Park in Grand Prairie. 

Strickland testified that the closest wells to Trinity’s leases were at DFW, but those 

wells were slightly shallower than the wells Trinity proposed and the thickness of 

the Barnett Shale was not as great. The wells near Lone Star Park were geologically 

similar in thickness and depth to the wells Trinity sought to drill. Trinity’s 

development plan called for wells with approximately 6000 foot lateral lengths 

therefore Strickland selected existing wells with lateral lengths of 5000 to 7000 feet 

and which began producing in 2005 to 2010. He used historical production from the 

wells meeting these criteria and developed an average curve using both good and 

bad wells. He then used that average or type curve to estimate the production from 

the wells in each of his scenarios. 

Strickland estimated future prices using price forecasts from several industry 

sources made in the summer of 2013. He testified that the expectation in the summer 
–23–

of 2013 was that gas prices would continue to rise. He then used estimated costs of 

production for Trinity’s proposed wells, including drilling and operating costs, water 

disposal, treatment of carbon dioxide, and costs for equipment and production 

facilities. 

Using these estimates, Strickland calculated a gross revenue stream, reduced 

that to the interest Trinity held, then subtracted the cost data to arrive at a yearly net 

cash flow. He then calculated the present value of that cash flow using industry 

metrics for discount rates. Finally, Strickland applied a 70% discount as a risk factor 

for Trinity’s property. 

The City contends that Strickland’s analysis was not reasonably certain 

because the only wells actually drilled, the University of Dallas wells, were not 

economic, Strickland’s proposed wells would have the same problems as the

University of Dallas wells, and gas prices had fallen since 2008. 

There was significant conflicting evidence about whether Trinity’s mineral 

interests would be productive; resolving those conflicts, however, was for the 

factfinder. See Ford, 252 S.W.2d at 563. 

The Barnett Shale is bounded on the eastern edge by a formation known as 

the Ouachita Thrust. Geologists for Trinity and the City testified that in general wells 

drilled on or to the east of this thrust will be poor but wells drilled to the west will 

be good. The evidence indicates that Trinity’s University of Dallas wells were on 

the Ouachita Thrust. Comparing to producing wells near Lone Star Park, Trinity 
–24–

determined that wells drilled four to five thousand feet northwest of the University 

of Dallas drill site would be productive because they would be west of the Ouachita 

Thrust. Trinity selected the three drill sites in the SUPs for this reason. Strickland 

testified that based on the thickness of the Barnett Shale, the quality of the rock, and 

laboratory testing from the University of Dallas science well, the wells from 

Trinity’s selected drill sites would have good productivity and an excellent chance 

of commercial gas production. 

Although gas prices in 2013 had fallen from the highs of 2008, Strickland 

used publicly available price forecasts from 2013 in his calculations. Those forecasts 

would have been available to buyers and sellers at the time. Further, Strickland’s 

testimony shows he took the additional costs associated with the University of Dallas 

wells into consideration in his analysis and included costs for water disposal and 

treatment of carbon dioxide, along with many other cost factors, in his calculations. 

We conclude that the City failed to show that Strickland’s discounted cashflow analysis was not reasonably certain. See Phillips, 475 S.W.3d at 280 (“[W]hen 

evidence of potential profits is used to prove the market value of an incomeproducing asset, the law should not require greater certainty in projecting those 

profits than the market itself would.”). 

4. Summary

Ultimately, the jury was presented with conflicting evidence on whether 

Trinity’s leases would be productive of gas had Trinity been permitted to drill from 
–25–

the drill site locations. “[T]he question of market value is peculiarly one for the fact 

finding body.” Texas Pipe Line Co. v. Hunt, 228 S.W.2d 151, 156 (Tex. 1950). 

The jury is the sole judge of the weight and credibility of the evidence, may 

resolve conflicting evidence, and is free to accept or reject all or any portion of an 

expert’s testimony. See Jackson, 116 S.W.3d at 761; McGailliard v. Kuhlmann, 722 

S.W.2d 694, 697 (Tex. 1986); Ford, 252 S.W.2d at 563. The jury also has discretion 

to award damages within the range of evidence presented at trial, so long as there is 

a rational basis for calculation. See Basic Capital Mgmt., Inc. v. Dynex Commercial, 

Inc., 402 S.W.3d 257, 265 (Tex. App.—Dallas 2013, pet. denied). The jury’s finding 

may not be set aside because its reasoning in arriving at the amount of damages is 

unclear. Baker v. Habeeb, No. 05-16-01209-CV, 2018 WL 1835566, at *9 (Tex. 

App.—Dallas Apr. 18, 2018, pet. denied). And while uncertainty as to the fact of 

damages is fatal, uncertainty as to the amount of damages does not defeat recovery.

Phillips, 475 S.W.3d at 279–80. 

In this case, the City thoroughly cross-examined Strickland and Trinity’s other 

witness about the complaints raised on appeal and presented those complaints to the 

jury. The jury exercised its broad discretion and found a value for Trinity’s property 

within the range of projections supported by the evidence. See Baker, 2018 WL 

1835566, at *9. We will not disturb the jury’s resolution of the conflicts in the 

evidence and its determination of the credibility of the witnesses. 
–26–

We conclude there is more than a scintilla of evidence supporting the jury’s 

finding of the fair market value of Trinity’s property before and after the denial of 

the SUPs. The evidence supporting that finding is not so weak as to render it clearly 

wrong and manifestly unjust. See Crosstex N. Tex. Pipeline, L.P., 505 S.W.3d at

615; Cain v. Bain, 709 S.W.2d 175, 176 (Tex. 1986). Accordingly, the evidence is 

legally and factual sufficient to support the trial court’s award of damages for inverse 

condemnation to Trinity. We overrule the City’s second and third issues. 

C. Submission of Value Question to the Jury

In its fourth issue, the City contends the trial court abused its discretion by 

submitting the fair market value questions to the jury before the court determined 

there had been a regulatory taking. The City argues the trial court should have 

bifurcated the trial and conducted a bench trial on the taking question before trying 

the issue of damages to the jury. 

While bifurcation may be appropriate in many cases, there is no bright-line 

rule requiring it and the trial court has broad discretion in determining whether to 

bifurcate the trial of an inverse condemnation case. See Tarrant Reg’l Water Dist. v. 

Gragg, 151 S.W.3d 546, 556–57 (Tex. 2004); TEX. R. CIV. P. 174(b). This case 

involved multiple causes of action with different damage theories, multiple 

witnesses, and several days of evidence. As in Gragg, separate trials would have 

resulted in considerable and unnecessary repetition of the evidence. Gragg, 151 

S.W.3d at 557. Further, the City has not shown it was prejudiced in any way by 
–27–

submission of the value question to the jury before the court determined there had 

been a taking. We conclude the trial court was within its discretion to submit the 

question to the jury and require only a single presentation of the evidence. We 

overrule the City’s fourth issue. 

Conclusion

We conclude the evidence is legally and factually sufficient to support the trial 

court’s findings and conclusions that the City denied Trinity all economically viable 

or beneficial use of its property resulting in a taking of the property for public 

purposes. The constitution requires payment of just compensation for such a taking. 

We also conclude the evidence is legally and factually sufficient to support the jury’s 

determination of the fair market value of Trinity’s property before and after the 

taking. Accordingly, we affirm the trial court’s judgment.
