Nahmias, Chief Justice. This case arises from Rockdale County’s denial of an application for a permit to build a QuikTrip on property owned by William Corey and U.S. Enterprises, Inc. (the “Owners”), on the ground that the proposed facility is a “truck stop,” which is a prohibited use under the County’s Unified Development Ordinance (“UDO”). After the County’s Board of Adjustment affirmed the denial of the permit, the Owners filed a petition in the Rockdale County Superior Court seeking, among other things, certiorari under OCGA § 5-4-1 et seq. The superior court sustained the petition for certiorari, rejecting the County’s argument that the Owners’ lawsuit was barred by res judicata and reversing the Board’s decision on the ground that the UDO’s applicable definition of a “truck stop” was unconstitutionally vague and therefore violated due process under the Georgia Constitution. See Ga. Const. of 1983, Art. I, Sec. I, Par. I (“No person shall be deprived of life, liberty, or property except by due process of law.”). After this Court granted the County’s application for a discretionary appeal, the County appealed, and the Owners then cross-appealed. For the reasons explained below, in the County’s appeal, we affirm the superior court’s rejection of the County’s res judicata argument, reverse the part of the superior court’s judgment ruling that the “truck stop” definition was unconstitutionally vague, and remand the case for further proceedings. Our holding makes it unnecessary to address the Owners’ cross-appeal, which we accordingly dismiss as moot.[1] 1. The record shows the following. In August 2019, the Owners applied to the County for a land disturbance permit to construct a QuikTrip “convenience store with fuel pumps” on 7.6 acres of their property that is located near Interstate 20 and zoned C-2, which allows for a “[g]asoline station with convenience store” but prohibits a “[t]ruck stop.” UDO §§ 218-1; 214-11. The site plans for the QuikTrip include four entrances to the parking lot; a 7,318 square feet convenience store; an 8,176 square feet canopy near the front of the store with 10 gasoline fueling stations for automobiles; a 4,193 square feet higher canopy with six diesel fueling stations near the back of the store; 69 parking spaces, including 14 spaces for heavy trucks; truck weigh scales; and air pumps. The Owners submitted “Constitutional and Statutory Challenges” with their permit application, asserting, among other things, that the proposed facility did not meet the UDO’s definition of a “truck stop” and that a denial of the permit would violate their right to due process under the Georgia Constitution because the definition of a “truck stop” was “overbroad, vague, and fail[ed] to set forth a standard [on] which a reasonable person could understand and rely.”[2] In September 2019, the County’s Planning and Development staff denied the Owners’ application on the ground that the proposed QuikTrip constituted a prohibited “truck stop.” Section 214-11 of the UDO says: “Truck stops are prohibited. Furthermore, no adjoining or adjacent uses shall be physically connected or used so as to effectively create a truck stop.” The UDO in effect at the time the Owners applied for the permit defined a “Truck stop” as follows: A prohibited use that includes any building, premises, or land in which or upon which a business, service, or industry involving the maintenance, servicing, storage, or repair of heavy trucks and similar commercial vehicles is conducted or rendered, including the dispensing of motor fuel or other petroleum products primarily for such heavy trucks and similar commercial vehicles and the sale of accessories or equipment for heavy trucks and similar commercial vehicles, as well as overnight accommodations, showers, overnight customer parking, or restaurant facilities for the use of crews of heavy trucks and similar commercial vehicles. UDO § 106-1 (c).[3] The UDO defines “Truck, heavy” as “[t]rucks, including truck tractors, and similar vehicles with two or more rear axles.” Id. The UDO defines “Vehicle, commercial” in pertinent part as “[v]ehicles with a gross vehicle weight rating . . . of 10,001 pounds or more used as a part of a business.”[4] Id. The UDO does not define “restaurant facilities,” but it defines “Restaurant” as “[a]n establishment in which the primary purpose is preparing, serving, and consuming food and beverages.” Id. Although the UDO prohibits truck stops in all zoning districts in the County, it permits “[g]asoline station[s] with convenience store[s]” in zone C-2, where the Owners’ property is located. UDO § 218-1. The UDO defines “ Gasoline station with convenience store” as “[a] gasoline station that includes a retail store that sells a limited line of groceries and household items.” UDO § 106-1 (c). Overnight accommodations, showers, and overnight parking are prohibited at gasoline stations with convenience stores, which “shall not be combined with any other use(s) or facility so as to create a truck stop.” UDO § 218-13 (aa) (11)-(12). Finally, the UDO says that all words not otherwise defined in the UDO “are intended to have the commonly accepted definitions contained in a recent edition of the Merriam-Webster Dictionary.” UDO § 106-1 (b) (4). The Owners appealed the Planning and Development staff decision to the County’s Board of Adjustment. See UDO §§ 238-7; 238-8 (conferring power to and setting forth the procedures for the Board of Adjustment to decide appeals from an administrative official’s decision enforcing the UDO). The Owners asserted in pertinent part that the proposed facility did not meet the UDO’s definition of a “truck stop” and that the denial of the permit violated their right to due process under the Georgia Constitution. The Board considered the appeal at a November 2019 meeting, during which the Owners argued, among other things, that the proposed QuikTrip did not meet the UDO’s definition of a “truck stop” because the facility would be used primarily for the sale of gasoline to automobiles and did not provide overnight accommodations or parking. The Board reserved ruling on the appeal so that the parties could submit more information about the proposed facility.[5] At a meeting on December 2, 2019, the Board voted unanimously to affirm the denial of the land disturbance permit. On December 23, 2019, the Owners filed a petition, which they later amended, in the Rockdale County Superior Court, seeking certiorari, a declaratory judgment, an injunction, mandamus, and attorney fees.[6] The Owners claimed, in pertinent part, that the “truck stop” section of the UDO violated the Georgia Constitution because it was “overbroad and violate[d] Due Process” and that the Board of Adjustment erred by determining that the proposed QuikTrip qualified as a “truck stop.” After the defendants and respondents filed motions to dismiss, the superior court issued an order on August 7, 2020, denying the motion to dismiss the certiorari claim but granting the motion to dismiss (without prejudice) the claims for declaratory judgment, injunction, and mandamus. After further briefing by the Owners, the County renewed its motion to dismiss the certiorari claim, arguing that the lawsuit was barred by res judicata because in 1999, the Owners had filed an unsuccessful lawsuit against the County challenging the denial of a land disturbance permit to build a “travel plaza” on the same property, and that the vagueness challenge was not properly raised. On August 24, 2020, the superior court heard oral arguments on the motion to dismiss. Near the end of the hearing, the court orally ruled that res judicata did not bar the Owners’ claims and that the UDO’s definition of a “truck stop” was “facially invalid on due process grounds because of vagueness and ambiguity.” On September 4, 2020, the court issued an order sustaining the Owners’ amended certiorari petition and reversing the Board of Adjustment’s decision denying the permit on the ground that the UDO’s definition of a “truck stop” was vague and therefore violated due process under the Georgia Constitution. The court ruled that the terms “maintenance,” “servicing,” “similar commercial vehicles,” “primarily,” “accessories,” and “restaurant” were vague. The court also said that it was unclear whether one or all of the requirements listed in the definition must be met because the definition did “not consistently say ‘or’ or ‘and’” and used “as well as,” which “seem[ed] to require all requirements to be met after that phrase.” The court noted that the County had argued during the hearing that the proposed QuikTrip’s entrances with large turning radiuses, raised canopy, scales, 14 parking spaces, and large area for trucks were indicia of a truck stop, but that none of those standards were set forth in the “truck stop” definition. The order did not expressly mention the County’s arguments that the lawsuit was barred by res judicata and that the court should not consider the vagueness challenge because the Owners had not properly raised it.[7] This Court granted the County’s application for a discretionary appeal to determine whether the superior court erred by ruling that the “truck stop” definition was unconstitutionally vague. In its appeal, the County contends that the Owners’ lawsuit was barred by res judicata, that the superior court should not have ruled on the merits of the vagueness challenge because the Owners did not properly raise it, and that the UDO’s definition of a “truck stop” was not unconstitutionally vague. In their cross-appeal, the Owners argue that if this Court concludes that the vagueness challenge was not properly raised, the superior court erred by dismissing the Owners’ claims for a declaratory judgment and an injunction related to their vagueness challenge. As we explain below, res judicata did not bar the Owners’ lawsuit, so we affirm that part of the superior court’s judgment. As for the Owners’ vagueness challenge, we can assume without deciding that it was properly raised, because we conclude on the merits that the superior court erred by determining that the “truck stop” definition was unconstitutionally vague; we therefore reverse that part of the court’s judgment. Based on these holdings, we remand the case to the superior court for it to rule on the Owners’ certiorari claim that the Board of Adjustment’s decision affirming the denial of the permit was not supported by substantial evidence. See OCGA § 5-4-12 (b) (“The scope of [certiorari] review shall be limited to all errors of law and determination as to whether the judgment or ruling below was sustained by substantial evidence.”). Because we decide the merits of the Owners’ vagueness challenge in the County’s appeal, it is unnecessary to address the Owners’ cross- appeal, which we dismiss as moot. See, e.g., Morgan County v. May, 305 Ga. 305, 309 n.5 (824 SE2d 365) (2019); Humphrey v. Walker, 294 Ga. 855, 856 (757 SE2d 68) (2014).[8] 2. The County contends that the Owners’ entire lawsuit was barred by res judicata. If that were true, then the superior court should not even have addressed the Owners’ vagueness challenge. But the County’s res judicata claim is meritless. The doctrine of res judicata prevents “‘the re-litigation of all claims which have already been adjudicated, or which could have been adjudicated, between identical parties or their privies in identical causes of action.’” Bostick v. CMMProperties, Inc., 297 Ga. 55, 57 (772 SE2d 671) (2015) (citation omitted). “[T]hree prerequisites must be satisfied before res judicata applies – (1) identity of the cause of action, (2) identity of the parties or their privies, and (3) previous adjudication on the merits by a court of competent jurisdiction.” Coen v. CDC Software Corp., 304 Ga. 105, 112 (816 SE2d 670) (2018). See also OCGA § 9-12-40 (“A judgment of a court of competent jurisdiction shall be conclusive between the same parties and their privies as to all matters put in issue or which under the rules of law might have been put in issue in the cause wherein the judgment was rendered until the judgment is reversed or set aside.”). We have explained that “cause of action” means “the entire set of facts which give rise to an enforceable claim[,] with special attention given to the ‘wrong’ alleged.” Coen, 304 Ga. at 112 (citations and punctuation omitted). In this case, the record shows that in August 1999 – more than seven years before the UDO, which contains the “truck stop” definition at issue in this case, was adopted – the Owners filed a petition for mandamus and declaratory relief against the County and, in their official capacities, the members of the Board of Commissioners and the Director of the Department of Public Services and Engineering. The Owners claimed that on July 22, 1999, they submitted an application for a land disturbance permit to construct a “travel plaza” on their property. Five days later, on July 27, the Board of Commissioners amended the zoning ordinance that was then in effect, which apparently did not include “travel plazas” or “truck stops” in its table of permitted uses for any zoning district, to allow truck stops only in M-2 zones.[9] On July 30, the County returned the Owners’ permit application, noting that it was “not acceptable for review,” and informed them that they would need to rezone the property before resubmitting the application. The Owners then sought a writ of mandamus compelling the defendants to review their application under the pre-amendment zoning ordinance that was in effect when the application was submitted, as well as a declaratory judgment that their application must be reviewed in accordance with the former ordinance, that a travel plaza was a permitted use under the former ordinance, and that the amendment to the former ordinance was invalid because it was improperly adopted. The Owners also asserted that if the travel plaza was not a permitted use under the former ordinance, the County’s prohibiting travel plazas and truck stops in all zoning districts was unconstitutional and the ordinance was not equally enforced. The defendants argued in response that a travel plaza was not a permitted use in zone C-2 under the former ordinance because it was not listed in the table of permitted uses and that the Owners’ application was incomplete and omitted required information. In September 1999, the superior court denied mandamus relief, ruling that the defendants did not abuse their discretion in returning the Owners’ application, as it was incomplete. In December 1999, the court also denied the Owners’ request for a declaratory judgment, concluding that because they had not resubmitted their application, there was no justiciable controversy. In early 2000, this Court denied the Owners’ application for a discretionary appeal and dismissed their direct appeal from the superior court’s orders. Although the Owners’ 1999 lawsuit and this case both relate to their seeking a permit to construct a facility on their same property, the two lawsuits are based on different sets of operative facts and different alleged wrongs. See Coen, 304 Ga. at 113. In the 1999 lawsuit, the Owners claimed that their application for a permit to build a “travel plaza” should be reviewed under a different zoning ordinance that was in effect many years before the UDO was enacted, that a travel plaza was permitted under the former ordinance, that an amendment to the former ordinance was invalid, and that parts of the former ordinance were unconstitutional (for reasons other than vagueness). The former ordinance and amendment apparently did not expressly define or expressly prohibit “truck stops.” In this case, the Owners claimed, in pertinent part, that their application for a permit to build a facility on the property was improperly denied under the express prohibition against “truck stops” in the UDO, which was adopted more than seven years after the 1999 lawsuit, and that the “truck stop” definition in the UDO was unconstitutionally vague. Accordingly, the lawsuits involved different causes of action, and the County’s argument fails at the first part of the res judicata test. See id. at 113. See also Haley v. Regions Bank, 277 Ga. 85, 91 (586 SE2d 633) (2003) (explaining that two causes of action were not identical for res judicata purposes because the prior action and the current lawsuit depended on a substantially different set of facts and involved questions that arose after and were not settled by the Court’s decision in the prior action). Cf. Shelley v. Town of Tyrone, 302 Ga. 297, 308 n.15 (806 SE2d 535) (2017) (explaining that the superior court correctly ruled that the plaintiff’s challenges to the town’s 1997 zoning ordinance and 2004 zoning amendment were barred by res judicata or collateral estoppel, because the plaintiff had filed an unsuccessful prior lawsuit challenging that particular ordinance and amendment, but leaving open the question of whether the plaintiff could challenge the town’s 2015 zoning ordinance). 3. The County also contends that the superior court erred by ruling on the merits of the vagueness challenge because the Owners did not properly raise it, and that even if the challenge was properly raised, the UDO’s definition of a “truck stop” was not unconstitutionally vague in violation of the due process provision of the Georgia Constitution. We need not decide whether the vagueness challenge was properly raised, because the Owners have not shown that the “truck stop” definition was unconstitutionally vague.[10] (a) As we have explained before, “[t]o withstand an attack of vagueness or indefiniteness, a civil [law] must provide fair notice to those to whom the [law] is directed and its provisions must enable them to determine the legislative intent.” Daniel v. Amicalola Electric Membership Corp., 289 Ga. 437, 443 (711 SE2d 709) (2011) (citation and punctuation omitted). Thus, only when an ordinance is “so vague that persons of common intelligence must necessarily guess at its meaning and differ as to its application” does it violate due process. Edwards v. City of Warner Robins, 302 Ga. 381, 386 (807 SE2d 438) (2017) (citation and punctuation omitted). Like statutes, ordinances are presumed to be constitutional, and the burden of proving a due process violation is on the party raising the vagueness challenge. See Zarate-Martinez v. Echemendia, 299 Ga. 301, 305 (788 SE2d 405) (2016). See also Jones v. City of Marietta, 248 Ga. 773, 773 (285 SE2d 730) (1982). “‘[E]very reasonable construction must be resorted to, in order to save [an ordinance] from unconstitutionality.’” Ga. Dept. of Community Health v. Northside Hospital Inc., 295 Ga. 446, 448 (761 SE2d 74) (2014) (citation omitted). See also Warshaw v. City of Atlanta, 250 Ga. 535, 536 (299 SE2d 552) (1983). Moreover, there is generally a greater tolerance of uncertainty in “‘enactments with civil rather than criminal penalties [,] because the consequences of imprecision are qualitatively less severe.’” Daniel, 289 Ga. at 443 (citation omitted). See also Village of Hoffman Estates v. Flipside, Hoffman Estates, Inc., 455 U.S. 489, 498 (102 SCt 1186, 71 LE2d 362) (1982) (noting that “economic regulation is subject to a less strict vagueness test”). The interpretation of a statute or ordinance and the determination of whether such a law is unconstitutionally vague are questions of law that we review de novo on appeal. See Jenkins v. State, 284 Ga. 642, 645 (670 SE2d 425) (2008). The Owners argue in this Court, as they did in the superior court, that the “truck stop” definition in the UDO was unconstitutionally vague on its face. And the superior court’s order, particularly when construed in light of the court’s oral ruling, appears to decide only that facial challenge, without expressly addressing whether the definition was vague as applied to the Owners’ proposed QuikTrip. As we have repeatedly made clear, however, “‘[v]agueness challenges . . . that do not implicate First Amendment freedoms must be examined in the light of the facts of the case to be decided.’” Wilbros, LLC v. State, 294 Ga. 514, 520 (755 SE2d 145) (2014) (quoting Parker v. City of Glennville, 288 Ga. 34, 35 (701 SE2d 182) (2010)). Accord Village of Hoffman Estates, 455 U.S. at 495 n.7. “In other words, outside of the First Amendment context, if a challenger’s as-applied vagueness challenge fails, then his facial challenge also fails.” Smallwood v. State, 310 Ga. 445, 447 (851 SE2d 595) (2020). “‘A court should therefore examine the complainant’s conduct before analyzing other hypothetical applications of the law.’” Catoosa County v. R.N. Talley Properties, LLC, 282 Ga. 373, 375 (651 SE2d 7) (2007) (quoting Village of Hoffman Estates, 455 U.S. at 495). See also State v. Raybon, 242 Ga. 858, 862 (252 SE2d 417) (1979) (rejecting the defendant’s facial vagueness challenge to a criminal trespassing statute that implicated no constitutionally protected conduct, in part because the defendant presented no evidence that the statute was vague as applied to him and he did “not have standing to raise the rights of other persons as to whom the statute may have been unconstitutionally applied”). The Owners’ vagueness challenge implicates no speech protected by the First Amendment. Thus, the superior court should have determined whether the “truck stop” definition in the UDO was unconstitutionally vague as applied to the Owners’ proposed use of their property before the court considered whether the definition was vague on its face.[11] As we explain below, the Owners have not established that the “truck stop” provision was unconstitutionally vague as applied to the proposed use of their property, so their facial vagueness challenge also fails. (b) As we recounted in Division 1 above, at the time the Owners applied for the land disturbance permit, the UDO defined a “truck stop” as: A prohibited use that includes any building, premises, or land in which or upon which a business, service, or industry involving the maintenance, servicing, storage, or repair of heavy trucks and similar commercial vehicles is conducted or rendered, including the dispensing of motor fuel or other petroleum products primarily for such heavy trucks and similar commercial vehicles and the sale of accessories or equipment for heavy trucks and similar commercial vehicles, as well as overnight accommodations, showers, overnight customer parking, or restaurant facilities for the use of crews of heavy trucks and similar commercial vehicles. UDO § 106-1 (c). The Owners’ property plainly constitutes “land” on which a “business” – the proposed QuikTrip – would be conducted. We therefore turn to the remainder of the definition. First, to qualify as a “truck stop,” the definition required that the business “involv[e] the maintenance, servicing, storage, or repair of heavy trucks and similar commercial vehicles.” Id. In its order ruling that the “truck stop” definition was unconstitutionally vague, the superior court concluded that the terms “maintenance” and “servicing” were ambiguous. The UDO does not define those two terms, so – as the UDO directs – we look to their definitions in “a recent edition of the Merriam-Webster Dictionary,” UDO § 106-1 (b) (4), construed in the context of the “truck stop” definition.[12] As defined in Merriam-Webster’s, in this context “maintenance” refers to “the act of maintaining” and “maintain” means “to keep in an existing state (as of repair).” See also Webster’s (defining “maintenance” specifically as “the work of keeping a building, machinery, etc. in a state of good repair”). Merriam-Webster’s defines “servicing” in this context as “to do maintenance or repair work on or for.” See also Webster’s (defining “servicing” as “to make or keep fit for service, as by inspecting, adjusting, repairing, refueling, etc.”). In light of these defined and commonly accepted meanings, the “truck stop” definition sufficiently informed a person of ordinary intelligence that to constitute a “truck stop,” a business must involve, among other things, the maintenance (i.e., keeping in a state of repair), servicing (i.e., doing repair work, such as by inspecting, adjusting, repairing, or refueling), storage, or repair of heavy trucks and similar commercial vehicles. Thus, the superior court incorrectly concluded that the words “maintenance” and “servicing” were impermissibly vague on their face. Following the requirement that a “truck stop” involve the maintenance, servicing, storage, or repair of heavy trucks and similar commercial vehicles, the “truck stop” definition listed several other requirements, which all appear in a lengthy phrase after the word “including.” To begin with, we generally read the word “including” in this context – following a general phrase and preceding a litany of specific terms – as introducing an exhaustive list of requirements rather than just some illustrative examples. See Premier Health Care Investments, LLC v. UHS of Anchor, L.P., 310 Ga. 32, 42-44 (849 SE2d 441) (2020). See also Merriam-Webster’s (defining “include” as “to take in or comprise as a part of a whole”). Indeed, the UDO uses the phrase “including but not limited to” in other provisions as a means of introducing non-exhaustive examples. See, e.g., UDO §§ 106-1 (c) (defining “Canopy” in pertinent part as “[a] roof structure constructed of rigid materials, including but not limited to, metal, wood, concrete, plastic or glass, which is attached to and supported by a building” (emphasis added)); 302-44 (“A land disturbance permit shall be issued to authorize all activities associated with development activity; including, but not limited to, clearing and grubbing, grading and the construction of such improvements as streets, surface parking areas and drives, stormwater drainage facilities, sidewalks, or other structures permanently placed on or in the property except for buildings, signs or other structures requiring the issuance of a building permit.” (emphasis added)). The superior court concluded that an ordinary person could not discern whether one, all, or some combination of the listed requirements in the phrase following “including” must be met, because the phrase uses the words “and,” “as well as,” and “or.” But the words “and” and “as well as” are normally understood in a conjunctive sense, and the context of the “truck stop” definition does not suggest a contrary interpretation. See Merriam-Webster’s (defining “and” as “used to indicate connection or addition esp[ecially] of items within the same class or type or to join words or phrases of the same grammatical rank or function”; and defining “as well as as “and in addition” and “in addition to”). See also Webster’s (defining “and” as “in addition; also; as well as”; and defining “as well as” as “in addition to”); Crooks v. Harrelson, 282 U.S. 55, 58 (51 SCt 49, 75 LE 156) (1930) (construing the word “and” between two phrases in a tax statute to mean “not one or the other, but both” and concluding, “[w]e find nothing in the context or in other provisions of the statute which warrants the conclusion that the word ‘and’ was used otherwise than in its ordinary sense”). Conversely, the word “or” normally “indicate[s] an alternative,” as Merriam-Webster’s explains. See also Webster’s (defining “or” as “a coordinating conjunction introducing an alternative” such as “introducing any of the possibilities in a series, but usually used only before the last”); Gearinger v. Lee, 266 Ga. 167, 169 (465 SE2d 440) (1996) (explaining that “or” is naturally understood as a “disjunctive term” that “mark[s] an alternative and present choice” and “where a legislative provision is phrased in the disjunctive, it must be so construed absent a clear indication that a disjunctive construction is contrary to the legislative intent” (citation and punctuation omitted)). In sum, an ordinary speaker of the English language generally would not say that “or” is equivalent to “and” or “as well as. Applying these commonly understood meanings as they appear in the context of the phrase beginning with “including” in the “truck stop” definition, an ordinary person would understand that the word “and” signifies that a “truck stop” must include the dispensing of motor fuel or other petroleum products primarily for heavy trucks and similar commercial vehicles in addition to the sale of accessories or equipment for such trucks and vehicles. The next term, “as well as,” precedes a list of four distinct alternatives connected by the word “or,” indicating that in addition to the dispensing and sale requirements, a “truck stop” must have at least one of those alternatives: overnight accommodations, showers, overnight customer parking, or restaurant facilities for the use of crews of heavy trucks and similar commercial vehicles. Accordingly, to constitute a “truck stop,” the business must: (1) involve the maintenance, servicing, storage, or repair of heavy trucks and similar commercial vehicles; (2) dispense motor fuel or other petroleum products primarily for heavy trucks and similar commercial vehicles; (3) sell accessories or equipment for heavy trucks and similar commercial vehicles; and (4) provide at least one of the following – overnight accommodations, showers, overnight customer parking, or restaurant facilities for the use of crews of heavy trucks and similar commercial vehicles. Finally, the superior court concluded that the terms “similar commercial vehicles,” “restaurant facilities,” “primarily,” and “the sale of accessories or equipment for heavy trucks and similar commercial vehicles” were ambiguous. But as noted in Division 1 above, the UDO clearly defines “Vehicle, commercial” and “Restaurant.” See UDO § 106-1 (c). And “primarily” means “for the most part.” Merriam-Webster’s. See also Webster’s (defining “primarily” as “mainly; principally”). As many courts have held, the use of that qualitative word does not render a law impermissibly vague. See, e.g., United States v. Gibson, 998 F3d 415, 419-420 (9th Cir. 2021) (“The phrase ‘primarily used by children’ is not indeterminate.”); In re Kelly, 841 F2d 908, 916 (9th Cir. 1988) (“[T]he modifier “primarily” is not a word that is ambiguous or difficult to understand.”); Pizza di Joey, LLC v. Mayor of Baltimore, 235 A3d 873, 907 (Md. 2020) (holding that “primarily engaged in” has a “generally accepted meaning[]“). Similarly, there is no mystery in the requirement that a “truck stop” sell “accessories or equipment for heavy trucks and similar commercial vehicles.” See Merriam- Webster’s (defining “accessory” in this context as “something helpful but not essential”; and defining “equipment” as “things used in equipping: outfit,” and “equip” as “to supply with needed resources” and “to make ready: prepare”). See also Webster’s (defining “accessory” as “a piece of optional equipment for convenience, comfort, appearance, etc.”; and defining “equipment” as the special things needed for some purpose; supplies; furnishings; apparatus, etc.”); UDO § 106-1 (c) (defining “Truck, heavy” and “Vehicle, commercial”). Thus, the pertinent definition of a “truck stop,” construed in light of the terms defined in the UDO and in the dictionary it points to as well as the tools we customarily use when interpreting legal texts, is comprehensible. To be sure, the definition could have been more artfully drafted – as the revamped definition enacted after the superior court’s order illustrates, see footnote 3 above – but “an ordinance need not regulate with mathematical certainty to comport with due process.” Burton v. Glynn County, 297 Ga. 544, 548 (776 SE2d 179) (2015) (citation and punctuation omitted). See also JIG Real Estate, LLC v. Countrywide Home Loans, Inc., 289 Ga. 488, 492 (712 SE2d 820) (2011) (“Where the legislative intent is clear and the statute provides fair notice of its meaning, this Court will not deem a statute unconstitutionally vague merely because it ‘could be more artfully drafted.’” (citation omitted)). And although it may be difficult in this case to determine whether the proposed QuikTrip meets the requirements of the “truck stop” definition, the fact that a case is close does not render an ordinance unconstitutionally vague. The uncertainty in a statute which will amount to a denial of due process of law is not the difficulty of ascertaining whether close cases fall within or without the prohibition of the statute, but whether the standard established by the statute is so uncertain that it cannot be determined with reasonable definiteness that any particular act is disapproved[.] Briggs v. State, 281 Ga. 329, 330 (638 SE2d 292) (2006) (citation and punctuation omitted). See also United States v. Williams, 553 U.S. 285, 306 (128 SCt 1830, 170 LE2d 650) (2008) (explaining that “[c]lose cases can be imagined under virtually any statute. The problem that poses is addressed, not by the doctrine of vagueness, but by the requirement of proof’); Banta v. State, 281 Ga. 615, 617 (642 SE2d 51) (2007) (noting that “‘the fact that application of the statute’s standards sometimes requires an assessment of the surrounding circumstances to determine if the statute is violated does not render it unconstitutional’” (citation omitted)).[13] The Owners argue that there are a variety of hypothetical scenarios to which the “truck stop” definition may be less intelligibly applied. For example, in arguing that the term “maintenance” is vague, the Owners posit that the “truck stop” definition would be unconstitutional if applied to a farmer who used his barn to change a tire on his dual rear-axle pickup truck because the pickup truck would be a “heavy truck” as defined by the UDO and changing the tire would amount to “maintenance.” The superior court similarly posed questions about hypothetical situations to illustrate its conclusion that “maintenance” was indefinite, asking, “If you add a quart of oil[,] are you ‘maintaining’ your [pickup] truck?” These abstract scenarios and questions fail to construe the term “maintenance” in light of its commonly accepted definition or within the context of the entire “truck stop” definition, as we have interpreted it above. But in any event, the Owners’ (and the superior court’s) reliance on hypotheticals is of no avail, because the Owners have not identified any aspect of the proposed use of their own property – the specific QuikTrip proposal at issue in this case – to which the definition of “truck stop,” as properly interpreted, cannot be intelligibly applied and would instead require pure guesswork at its meaning. See Holder v. Humanitarian Law Project, 561 U.S. 1, 22-23 (130 SCt 2705, 177 LE2d 355) (2010) (rejecting the plaintiffs’ as- applied vagueness challenge to a criminal statute where they argued in part that certain statutory definitions would be difficult to apply in hypothetical situations, because even if there might be “theoretical doubts” regarding the definitions, the plaintiffs’ “‘case present[ed] no such problem,’” so the plaintiffs could not “seek refuge in imaginary cases” (citation omitted)). See also Catoosa County, 282 Ga. at 375; Raybon, 242 Ga. at 862. Indeed, even though the Owners may disagree with the conclusion reached by the Board of Adjustment that their proposed use of the property constituted a “truck stop,” the Owners do not assert that the definition of a “truck stop” was impermissibly vague as applied to their proposal. In sum, the UDO’s “truck stop” definition provided fair notice to the Owners of the sort of facilities that were prohibited. The Owners have not established that the “truck stop” definition was unconstitutionally vague as applied to their proposed QuikTrip, and the superior court therefore erred by concluding that the definition was vague on its face. See Smallwood, 310 Ga. at 447. Accordingly, we reverse that part of the court’s judgment. 4. Because we have concluded that the Owners’ lawsuit was not barred by res judicata and that the applicable “truck stop” definition in the UDO was not unconstitutionally vague, we remand the case for the superior court to rule on the Owners’ certiorari claim that the Board of Adjustment’s decision affirming the denial of the permit was not supported by substantial evidence. We express no opinion on that issue. Judgment affirmed in part and reversed in part in Case No. S21A0718, and case remanded with direction. Appeal dismissed in Case No. S21X0719. All the Justices concur, except Ellington, J., who dissents as to Division 3. Ellington, Justice, dissenting in part. The majority opinion does a fine job of deconstructing the section of the version of the Unified Development Ordinance applicable to these property owners that defines “truck stop,” Section 106-11, and reconstructing it for clarity. On remand, the superior court will consider whether, under the majority opinion’s construction of the applicable version of the ordinance, the Board of Adjustment’s decision to affirm the denial of the permit on the basis that the owners’ planned QuikTrip station constitutes a truck stop, which is a prohibited use under Section 214-11 of the ordinance, was “sustained by substantial evidence.” The owners may yet prevail. Be that as it may, in resolving the owners’ constitutional challenge to the ordinance, the superior court was tasked with deciding whether the applicable iteration of the ordinance sufficiently informed a person of ordinary intelligence whether a proposed use of property was an otherwise-permissible gasoline station with a convenience store or whether it was instead an impermissible truck stop. Due process demands that Rockdale County’s truck stop ordinance be sufficiently plain so that the County’s Department of Planning and Development could render a decision about whether to permit the owners’ intended use of their property that was not arbitrary or discriminatory and so that the County’s Board of Adjustment could fairly review the denial of a permit.[14] The record shows that the Board of Adjustment affirmed the department’s denial of the owners’ application for a permit solely on the basis that the owners’ intended use of their property constituted a truck stop, as defined in Section 106-11.[15] After hearings, the superior court sitting as a court of review of the administrative decision determined that the ordinance then in effect was not sufficiently plain for the officials who are responsible for deciding whether to permit the owners’ intended use of the property to fairly decide whether the intended use constituted a truck stop.[16] Seeing the tortured path the majority opinion takes to impose clarity on the applicable version of the ordinance, I find the superior court’s assessment to be persuasive.[17] If it takes, not just lawyers, which many of the local officials charged with making these decisions on a regular basis are not, but constitutional legal scholars, so much research and analysis to decide whether, and to explain why, an ordinance is not vague and ambiguous, perhaps we should not be so willing to override the superior court’s decision to the contrary. In my view, the superior court’s analysis was sound and should not be disturbed. Therefore, I respectfully dissent as to Division 3.
