OPINION
This аppeal concerns an ordinance enacted in 1997 by appellee the City of Houston that strengthened existing regulations for issuing permits to operate sexually-oriented businesses (“SOBs”). Appellants are ten SOB owners who were denied, in whole or in part, their requests for additional time to recoup their investments before being subject to the ordinance. They sought judicial review of these decisions, and the trial court upheld the decisions. Appellants argue that the trial court applied an incorrect standard of review and erred in refusing to require the hearing officers who denied their requests to make fact findings. They also contend that the conduct of the hearing officers violated their rights to due process and due course of law and the proceedings were violative of the separation of powers clause in the Texas Constitution. We affirm.
BACKGROUND
In 1997, the City of Houston enacted Ordinance 97-75. This ordinance amended existing ordinances regulating SOBs, including those regulating where SOBs could be located. Appellants held valid permits to operate SOBs, but under the new ordinancе, appellants could no longer operate in their current locations. To give business owners affected by the new ordinance time to recoup their investments and adjust to the new regulations, the ordinance did not go into effect for 180 days. Furthermore, the ordinance contains a procedure known as amortization whereby an affected business owner could apply for additional time to operate under the existing regulations by proving it needed that time to recoup his investment. Each appellant applied for additional time and, at a hearing, provided evidence to a hearing officer to justify its request. The hearing officers denied appellants’ requests, either in whole or in part. The ordinance provides that anyone aggrieved by such a decision can seek judicial review immediately following the decision.
Meanwhile, many SOB owners, including all appellants, brought a federal lawsuit challenging the constitutionality of the ordinance under many different theories.
See N.W. Enters., Inc. v. City of Houston,
The City and the SOB owners agreed that amortization hearings would continue during the pendency of the federal constitutional litigation but that any judicial review of those decisions would be stayed until entry of a final judgment. After the federal district judge denied the post-judgment motions, appеllants filed the present judicial review suit in Texas district court. 2 The trial court affirmed the hearing officers’ decisions regarding appellants’ requests for additional time to recoup their investments, and this appeal followed.
ANALYSIS
A. Timeliness
Before we analyze appellants’ issues, we begin with the City’s cross-issue. The City argues that appellants’ judicial review suit is untimely. The parties reached an agreement, which was entered as an agreed order in federal district court, that judicial review of the amortization decisions would be stayed until there was a final judgmеnt in the federal case. The order provided that upon “entry of a final judgment,” the judicial review process would begin according to the procedures set forth in the ordinance. The ordinance provides that any judicial review is to begin “immediately” following an adverse decision and states that any decision is not enforceable for twenty days in order to give the aggrieved party an opportunity to seek judicial review. 3 Therefore, according to the City, the time frame for judicial review began on January 31, 2007, when the federal court entered the judgment. Because appellants did not seek judicial review within twenty days of this date but rather waited until twenty days after the federal court denied its post-judgment motions, the City argues that the judicial review suit is untimely. We disagree with the City’s analysis.
In their agreement, the parties included a provision that the period of time for stay of judicial review ends with entry of a final judgment. Because the agreement was made in federal court, we will look to federal law regarding finality of judgments. Though the judgment entered on January 31, 2007 may have been a final judgment at the time of entry, that changed when the owners filed several post-judgment motions, including a motion to amend or make additional findings under Federal Rule of Civil Procedure 52(b) and a motion to alter or amend the judgment under Federal Rule of Civil Proce
*217
dure 59(e). Such motions destroyed the finality of the judgment because the court’s ruling on the motions could obviate the need for an appeal.
See Leishman v. Associated Wholesale Elec. Co.,
B. Standard of Review
Appellants complain that the trial court applied an improper standard in its judicial review of the hearing officers’ decisions. The trial court reviewed the hearing officers’ decisions for substantial evidence, which is a limited, deferential standard requiring only more than a mere scintilla of evidence to uphold the decisions.
See Montgomery Indep. Sch. Dist. v. Davis,
Neither the ordinance nor any other governing statute specifies the type or details of the judicial review procedure to be applied.
4
Therefore, we look to case law for guidance. Appellants cite the following case in support of their de novo judicial review theory,
City of Houston v. Lurie,
C. Fact Findings
Appellants next complain that the trial court erred in not remanding with instructions for the hearing officers to make findings of fact explaining the basis of their decisions. The hearing officers sent a letter to each appellant containing language stating that after “carefully considering]” the records, evidence, and testimony submitted, the request for an extension was denied. Appellants requested that the hearing officers provide fact findings to explain why their requests were not granted in full, but the hearing officers refused, with the City contending that there was no requirement for the hearing officers to do so.
On appeal, appellants argue that the hearing officers were required to make findings of fact and disclose the thought processes and motivations for their decisions. ' However, the ordinance does not require that level of detail. The ordinance states that an owner invoking the amortization procedures must “prove[] that he will be unable to recoup his investment in the business” by the effective date of the ordinance. The ordinance then requires the hearing officer to grant or deny the request, and if granting, to provide a specific date for the extension to end. A hearing officer’s negative decision on this narrow issue — of whether the owner met its burden of proving inability to recoup his investments in time — constitutes an implied finding that the owner did not meet its burden of proof. Although appellants cite Texas Rule of Civil Procedure 296 in arguing that fact findings are mandatory in response to a request, the rules of civil procedure apply to district courts, and appellаnts cite no authority to suggest they should also apply to a municipal, non-judicial officer. The same is true of the fact-finding requirement provided in Government Code section 2001.141, which applies only to state agencies. See Tex. Gov’t Code Ann. §§ 2001.001, .141 (Vernon 2008).
Appellants maintain that detailed fact findings are a necessary prerequisite to conduct a substantial evidence review, relying on
Morgan Drive Away, Inc. v. Railroad Commission of Texas,
D. Substantial Evidence
Having determined that substantial evidence is the proper standard for judicial review and that additional fact findings were unnecessary, we must now determine whether the trial court сonducted a proper substantial evidence review. The substantial evidence rule is a limited standard of review and grants significant deference to agency expertise.
R.R. Comm’n of Tex. v. Torch Operating Co.,
Appellants all argue that the trial court improperly speculated about
*220
what a reasonable hearing officer could have determined. However, as discussed above, looking at what a reasonable hearing officer could have concluded is entirely appropriate.
See City of El Paso,
Ice Embassy and Texas Richmond each had the burden to prove that they needed additional time to recoup their investment before complying with the ordinance. The trial court provided several reasons for each appellant explaining why, based on the evidence presented, the hearing officer could have reasonably rejected its calculation of the amount of additional time needed. For example, both Ice Embassy and Texas Richmond asserted that they had realized “zero” return on their investment and asked for 282 years (Ice Embassy) and 106 years (Texas Richmond) to recoup thеir investments. The trial court stated that a reasonable hearing officer could have found that such an exaggerated request was not credible. We agree. It is not unreasonable to determine that business owners did not invest in a business with no expectation of recovering on their investment for more than a century. 7 The rejection of Ice Embassy and Texas Richmond’s conclusions that more than 100 years was necessary to recoup their investments could also naturally lead to a rejection of the evidence upon which that conclusion was based. Further, the trial court pointed out several specific problems that a reasonable hearing officer could have had with appellants’ evidence. For example, each submitted a lease to show an obligation to stay in its current location and that relocation could subject it to liability for breach of contract. However, both leases were between the business owner and a related entity, and the signatures for landlord and tenant on each lease were signed by the same person. As the trial court noted, a reasonable hearing officer could have concluded that appellants were unlikely to face liability for breach of contract under these circumstances. 8 Additionally, the evidence appellants submitted showed that both had paid officers and stockholders substantial sums in prior years, including at least one payment of more than $500,000. Appellants argue that large executive salaries are common and that these executives earned this money. However, as the trial court *221 stated, it would not have bеen unreasonable to conclude that such high payments were at least in part a return on investment rather than a salary obligation. The trial court also noted that appellants included in the calculations of amounts invested in the business items that a reasonable hearing officer could have concluded were not in fact investments, including contingent liabilities (in the form of reserves for potential future litigation) and relocation and moving expenses.
After reviewing the record, we conclude there is more than a mere scintilla оf evidence to support the hearing officers’ actions. We further conclude it was not unreasonable for the hearing officer to reject Ice Embassy’s and Texas Richmond’s calculations and to find that they had not met their burden of proving they needed time to recoup their investments. For these reasons, we overrule appellants’ issues regarding whether there was substantial evidence to support the hearing officers’ determinations and the trial court’s application of substantial evidence judicial review.
E. Constitutional Issues
Appellants assert two constitutional arguments. 9 First, they contend that the ordinance violates the separation of powers clause of the Texas Constitution because judicial review without detailed fact finding is ineffective and because the hearing officers, who were from the police department vice squad, were usurping a judicial function. Second, they argue that the lack of detailed fact findings from the hearing officers violates their rights to due process and due course of law under the United States and Texas Constitutions 10 because they are forced to guess at the hearing officеrs’ motivations for declining their amortization requests.
The City asserts that these constitutional arguments are barred by res judicata.
11
We agree. The doctrine of res judicata bars a second action by the same parties on matters actually litigated in a prior suit as well as claims that, through the exercise of due diligence, could have been litigated.
See Hallco Tex., Inc. v. McMullen County,
Even if not barred by res judicata, appellants’ constitutional claims fail on the merits. The separation of powers provision of the Texas Constitution applies only to the branches of state, not local, government.
See City of Fort Worth v. Zimlich,
As to their due process claims, appellants are correct that due process applies to the administrative proсess.
See Rector v. Tex. Alcoholic Beverage Comm’n,
For these reasons, we overrule appellants’ issues alleging separation of powers and due process violations.
CONCLUSION
We conclude that appellants timely filed their judicial review suits and therefore overrule the City’s cross-issue. The trial court correctly applied the substantial evidence standard of review and correctly found that substantial evidence supports the hearing officers’ decisions, which were not required to be accompanied by detailed fаct findings. Moreover, appellants’ constitutional arguments are barred by res judicata and are otherwise without merit. For these reasons, we overrule all of appellants’ issues and affirm the trial court’s judgment.
Notes
.The district court enjoined enforcement of a portion of the ordinance.
See
. The present case is a consolidation of nine different judicial review actions filed by a total of twelve plaintiffs.
. Although the ordinance does not specifically state when judicial review suits are due, the City argues that, based on the language and intent of the ordinance, any judicial review suit is due within twenty days of the date of decision. For purposes of this appeal, none of the appellants have disputed this theory.
. The Government Code provides detailed procedures for judicial review of agency decisions. See Tex. Gov't Code Ann §§ 2001.171-.178 (Vernon 2008). However, these provisions are specifically limited to decisions of state agencies. See id. § 2001.171.
. At oral argument, appellants argued that all judicial review necessarily presupposes findings of fact and conclusions of law, citing the definition of "judicial review” in
Black’s Law Dictionary.
Though the third definition is "[a] court’s review of a lower court's or administrative body’s factual or legal findings,” the first one more generally refers to "[a] court's power to review the actions of other branches or levels of government.” Black's Law Dictionary 924 (9th ed. 2009). Further, as appellants have noted in this appeal, judicial review can be de novo, and in such a case, the agency's fact findings (or lack thereof) are irrelevant because the reviewing body must conduct a new trial.

Life Ins. Co. v. State Bd. of Ins.,
.In their joint brief, appellants A.H.D. Houston, Inc., D.N.W. Houston, Inc., and D. Rankin, Inc. purport to challenge the trial court's explanations, but they provide no analysis in their brief. Rather, they state that ''[f]or the reasons set forth in Appendix 16,” they are entitled to remand. Appendix 16 is a list of objections they filed in the trial court to the City’s proposed findings of fact and conclusions of law. This is insufficient. All arguments must be in the briefs; incorporating by reference arguments made in another document does not present an issue for appellate review.
See Young v. Neatherlin,
. Ice Embassy and Texas Richmond do not even attempt to argue that the number of years requested for recoupment was reasonable, only that it was justified by their fear of the future consequences of the ordinance.
. Further, the day before the ordinance passed, Texas Richmond entered into a lease аddendum extending its lease over twelve more years with an increase in rent, despite being aware of the ordinance well before its passage date. The hearing officer could have rationally discounted this expense as unreasonable.
. Ice Embassy and Texas Richmond also argue that a stay of enforcement to allow proper fact findings would protect their rights under the First Amendment. We need not consider this argument because we have concluded they are not entitled to a remand for fact findings.
.
See
U.S. Const, amend. XIV, § 1; Tex Const art. I, § 19. Althоugh the federal due process and Texas due course of law clauses are worded differently, there is no meaningful distinction between the two, and we apply general due process concepts to analyze both types of claims.
See Univ. of Tex. Med. Ctr. at Houston v. Titan,
. Appellants argue the City has waived its res judicata defense because it was not pleaded. The City had no obligation to plead res judicata as an affirmative defense except in response to a preceding pleading.
