INTRODUCTION
T1 This case arises from the decision of the Payson City Council (Payson City or City Council) to deny Plaintiffs' two applications to rezone property within Payson City (the property) from R-1-A low density residential/agricultural use to R-2-75 high density residential use. The trial court determined that Payson City's decision was arbitrary and capricious because it was not supported by "substantial evidence." The court of appeals reversed the decision of the trial court, holding that application of the "substantial evidence" standard was erroneous because Pay-son City's zoning decision was a legislative decision. Bradley v. Payson City,
BACKGROUND
T2 The Plaintiffs below are owners of property in Payson City zoned as R-1-A, which is a low-density residential zone. The property is located west of Interstate 15 (I-15) and is surrounded by property that is also zoned R-1-A. Some two and one-half blocks east of the property is a large area of land that is zoned R-2-75, which is the same zoning designation the Plaintiffs seek. The 1995 Payson City General Plan (General Plan), which was in effect at the time the Plaintiffs sought rezoning, forecasts primarily residential land use east of I-15 and industrial and agricultural uses for property west of I-15. While the intent of the General Plan seems to be to utilize I-15 as a natural buffer between residential and industrial uses, the Payson Planning Zone Map (Payson Zone Map), also adopted in 1995, does provide for some areas of residential use west of I-15.
T3 In January 1996, the Plaintiffs applied to rezone their property from R-1-A to R-2-75, which is a residential zoning designation that permits multiple family dwellings. During a meeting before the Payson City Planning Commission (Planning Commission) on the issue of the rezone application, the Chairperson acknowledged that because "there are already other residential developments in the surrounding area where this rezone would take place, there may not be a problem in rezoning this to R-2-75." After considering the Plaintiffs' R-2-75 rezone application, the Planning Commission Staff Report recommended that the Planning Commission recommend approval of the rezone to the Pay-son City Council.
T4 At the public hearing before the Planning Commission on Plaintiffs' rezone application, a petition signed by thirty-eight people was submitted by a neighborhood group that opposed the zoning change. In addition, thirteen individuals at the hearing expressed their opposition to the R-2-75 rezone. The public opposition voiced concerns over the adequacy of the area's infrastructure as well as concerns about maintaining the agricultural nature of the area, which includes using the land for raising horses. Several public comments also supported the rezone. After public comment, the Planning Commission recommended that the Payson City Council deny the R-2-75 rezone.
T5 The City Council then held a public hearing on the R-2-75 rezone application. The same thirty-eight signature petition was submitted to the City Council, and, subject to one or two exceptions, the same individuals appeared before the City Council as before the Planning Commission. In addition to voicing concerns about raising animals and preserving the nature of the neighborhood, other comments raised concerns about traffic levels in the area. Advocates of the application, including planning expert Jim Wilbert, expressed the area's need for low income housing. Ultimately, the City Council voted to deny the rezoning based upon the General Plan, traffic concerns, and the Planning Commission's recommendation.
T7 The Plaintiffs commenced this action by verified complaint on April 1, 1997. They alleged that the Payson City Council's denials of their rezone requests were arbitrary and capricious and that the denials constituted a taking without just compensation. Payson City filed a motion for summary judgment, requesting that the district court dismiss the complaint because the Payson City Council had acted within its legislative prerogative. The Plaintiffs responded by filing a cross-motion for summary judgment. The trial court entered a Memorandum Decision on January 22, 1999, reversing the City Council's denial of the Plaintiffs' R-2-75 rezone application, finding that the denial had no evidentiary support and was therefore arbitrary and capricious. Consequently, the district court did not address the denial of Plaintiffs' second rezone application.
18 Payson City appealed the trial court's decision directly to this court, after which this court transferred the appeal to the court of appeals pursuant to Utah Rule of Appellate Procedure 44. On January 11, 2001, the court of appeals issued an opinion reversing the district court's decision, concluding that the trial court had applied the incorrect standard of review to Payson City's legislative land use decisions and that under the "reasonably debatable" standard, Payson City's denial of the rezoning requests was not arbitrary, capricious, or illegal.

STANDARD OF REVIEW
T9 When reviewing a city council's decision not to change the zoning classification of property, we presume that the decision is valid and "determine only whether or not the decision is arbitrary, capricious, or illegal." Utah Code Ann. $ 10-9-1001(8) (1999). The principal issue in this case is the meaning of "arbitrary and capricious" in the context of Payson City's decision not to change the zoning classification of the Plaintiffs' property. This is a legal issue which we review for correctness. Springville Citizens for a Better Cmty. v. City of Springville,
ANALYSIS
I. APPROPRIATE STANDARD OF REVIEW GOVERNING APPEALS OF MUNICIPAL LAND USE DECISIONS
A. Distinction Between Legislative and Administrative Actions
110 This court has long recognized that municipal land use decisions should be upheld unless those decisions are arbitrary and capricious or otherwise illegal. Gayland v. Salt Lake County,
$11 There is no dispute in this case that the enactment and amendment of zoning ordinances is fundamentally a legislative act. Sandy City v. Salt Lake County,
12 We have long recognized that zoning decisions that are made as an exercise of legislative powers are entitled to particular deference. In Crestview-Holladay Homeowners Ass'n. Inc. v. Engh Floral Co., we noted that
[tlhe prior decisions of this court without exception have laid down the rule that the exercise of zoning power is a legislative function to be exercised by the legislative bodies of the municipalities. The wisdom of the zoning plan, its necessity, the nature and boundaries of the district to be zoned are matters which lie solely within that discretion. -It is the policy of this court as enunciated in its prior decisions that it will avoid substituting its judgment for that of the legislative body of the municipality.
113 In light of the particular deference we accord legislative zoning decisions, we have regularly distinguished zoning decisions that are made as a function of legislative power from decisions that are made as an exercise of either administrative or quasi-judicial power. Legislative zoning decisions involve the determination and enactment of zoning policies and cannot be delegated to other governmental bodies. Sandy City,
B. The "Reasonably Debatable" and "Substantial Evidence" Tests
114 As mentioned at the outset, our recognition of the distinction between legislative and administrative or quasi-judicial municipal powers has consistently determined the proper standard of review applicable to
115 For administrative or quasi-judicial land use decisions, however, the substantial evidence test has traditionally applied. We have defined substantial evidence as "that quantum and quality of relevant evi-denee that is adequate to convinee a reasonable mind to support a conclusion." First Nat'l Bank of Boston v. County Bd. of Equalization,
II, MEANING AND EFFECT OF UTAH CODE SECTION 10-9-1001(3) AND THE SPRINGVILLE CITIZENS CASE
1 16 The Plaintiffs do not dispute the existence of the traditional distinction between the standard of review applicable to legislative as opposed to administrative and quasi-judicial land use decisions. Rather, they claim that since the Utah Legislature's adoption of Utah Code section 10-9-1001 and this court's decision in Springville Citizens for a Better Community v. City of Springville,
117 The starting point for the Plaintiffs' "one-size-fits-all" approach to the standard of review for municipal land use decisions is the Utah Legislature's 1991 enactment of Utah Code section 10-9-1001. That provision codified the procedures for appealing municipal land use decisions. Section 10-9-1001(8) addresses the judicial standard of review for such decisions, stating:
(8) The courts shall:
(a) presume that land use decisions and regulations are valid; and
(b) determine only whether or not the decision is arbitrary and capricious, or illegal.
Utah Code Ann. § 10-9-1001(8) (1999). The Plaintiffs argue that section 10-9-1001(8) was intended to create a single standard of review for all municipal land use decisions and that it impliedly overrules this court's earlier decisions applying different interpretations of the arbitrary and capricious standard to different exercises of municipal power.
$18 "When construing statutory language which is plain and unambiguous, we do not look beyond the same to divine legislative intent." Cole v. Jordan Sch. Dist.,
{19 To support their claim that section 10-9-1001(3) does indeed apply to all three kinds of municipal land use decisions, the Plaintiffs rely on our opinion in Springville Citizens. In that case we stated, "(al municipality's land use decision is arbitrary and capricious if it is not supported by substantial evidence." Springville Citizens,
120 The dispute in Springville Citizens arose out of Springville City's approval of a planned unit development (PUD) pursuant to city ordinances. Springville Citizens,
1 21 In holding that Springville City's decision was not arbitrary and capricious, we did not discuss whether the decision was legislative, administrative, or quasi-judicial: we stated simply that "[a] municipality's land use decision is arbitrary and capricious if it is not supported by substantial evidence." Id. at 1 24. The Plaintiffs read this language as announcing a uniform standard of review for all municipal land use decisions. Nothing in Springville Citizens, however, evidences this court's intent to abandon the traditional distinction between the standard of review for legislative, administrative or quasi-judicial decisions. Furthermore, nothing in Spring-ville Citizens suggests, as the Plaintiffs argue, that the legislature's 1991 enactment of section 10-9-1001(8) affected our application of the arbitrary and capricious standard to different exercises of municipal power. The essence of the Plaintiffs' argument is that Springville Citizens overruled the cases recognizing the legislative/administrative distinction by implication.
€ 22 For its part, Payson City has tried to reconcile Springville Citizens with this court's prior municipal land use cases by explaining that the decision in that case was an administrative one that required application of the substantial evidence test. Payson City argues that all of the issues we addressed in Springville Citizens arose from the administrative processing of the PUD application pursuant to the standards set forth in city ordinances. Specifically, they note that the court focused on the certification of drawings by an irrigation company, Springville Citizens,
928 Thus, what the Plaintiffs describe as a "sweeping statement" of a new "one-size-fits-all" standard of review in Springville Citizens was nothing more than a recognition that both the parties and the court agreed that the challenged action was administrative and should be subject to the substantial evidence test. The absence of an acknowledgment of the distinction between legislative and administrative decisions in Springville Citizens stemmed solely from the fact that the standard of review was not a contested issue in that case. Therefore, we decline the invitation to treat Springville Citizens as a deviation from our traditional application of the arbitrary and capricious standard to different types of municipal land use decisions. 2
III. UNDER THE REASONABLY DEBATABLE STANDARD PAYSON CITY'S DENIAL OF THE PLAINTIFFS' REZONING REQUEST WAS NOT ARBITRARY AND CAPRI CIOUS
124 Having concluded that the reasonably debatable standard applies to legislative municipal land use decisions, we now proceed to evaluate whether Payson City's denial of the Plaintiffs' rezoning request was arbitrary and capricious under that standard. In general, because a "zoning classification reflects a legislative policy decision," we will not interfere with that decision "except in the most extreme cases." Harmon City,
25 The Plaintiffs argue that the court of appeals erred in holding that Payson City's denial of their rezoning request was not arbitrary and capricious under the reasonably debatable standard. The Plaintiffs argue that there was a general lack of evidence presented to the Payson City Council to support the reasonableness of its denial of the rezone application. The Plaintiffs further argue that the basis of Payson City's decision contradicted some record evidence supporting the zoning change. We will address each of the Plaintiffs' specific arguments in turn.
127 Additionally, the Plaintiffs assert that Payson City "almost exclusively relied on public comment[s]" made at the public hearing before the city council as a basis for the denial of their rezoning proposal and argue that citizen opposition alone cannot be the basis for the municipality's action. See Davis County v. Clearfield City,
128 It is beyond question, however, that public hearings and citizen comments are a legitimate source of information for city council members to consider in making legislative decisions. See Harmon City,
129 Like the court of appeals in its decision below, we are satisfied that Payson City's consideration of public comments as a justification for its zoning decision reflects a reasonable judgment that properly took into account citizens' concerns. The court of appeals cited a number of items in the record to support this conclusion:
Specifically, two businesses in the area expressed concern over the compatibility of higher density residential areas with their businesses and the neighboring industrial zones. One of the businesses submitted a letter detailing why it located in the area. This business stated it was attracted to the area because the "master plan ... was far sighted enough to separate the industrial area from the residential area by a natural break." The business stated that it operates twenty-four hours a day with "bright dock lights, and large trucks ... all of which would be a concern for the future residential area that is proposed." Another businessman in the area testified that because his business was contiguous to the proposed zone change he felt he would be out of business within a year because neighboring residents would not tolerate the noise and smell from his fruit processing plant.
Bradley,
T380 Furthermore, with respect to the Plaintiffs' argument that there was no evi-dentiary support behind public comments about increased traffic, we simply note that a city council is not required to receive advice from experts before making a legislative zoning decision. Moreover, we are not persuaded that the comments of the Plaintiffs' planning expert, Jim Wilbert, cast doubt on the reasonability of Payson City's decision. Mr. Wilbert spoke at the public hearing in favor of the zone change because it would bring affordable housing to the nearby industrial center. However, even assuming that affordable housing is an important addition to the city plan, Mr. Wilbert's comments do not directly refute the concerns raised by local business owners and other residents about the compatibility of high-density residential housing in the industrial and agricultural zones. See Bradley,
{31 Finally, the Plaintiffs challenge Pay-son City's reliance on the Planning Commission's negative recommendation as a basis for the rezone denial. The Plaintiffs contend that the Planning Commission's decision was predicated entirely on neighboring citizens' opposition to the proposed rezone and that reliance on such views was an unreasonable basis for the zoning decision. In light of our holding that it was reasonable for the City Council to rely on public comments in making its decision, we need not also address the reasonability of the Planning Commission's similar reliance.
IV. THE COURT OF APPEALS DOES NOT HAVE ORIGINAL APPELLATE JURISDICTION OVER CASES ARISING FROM LAND USE DECISIONS BY LOCAL GOVERNMENTAL ENTTTIES
132 Payson City originally appealed the trial court's reversal of the City Council's decision to deny the Plaintiffs' rezone application directly to this court. Bradley,
33 Under Utah Code section 78-2a-8, the court of appeals has original jurisdiction to hear appeals from trial court review of "adjudicative proceedings of agencies of political subdivisions of the state or other local agencies." Utah Code Ann. § 78-22-83@)(b)M) (2002) (emphasis added). This provision is designed to establish a body of expertise in the court of appeals for review of such "adjudicative proceedings" under the Utah Administrative Procedures Act. Utah Code Ann. §§ 63-46b-0.5 to -22 (1997 & Supp.2001). The Utah Administrative Procedures Act governs "all state agency actions." Id. § 683-46b-1(1)(a). An "adjudicative proceeding" is specifically defined as an action by a state agency under the Administrative Procedures Act. Id. § 68-46b-2(1)(a). The Act specifically excludes from the definition of "agency" "any political subdivision of the state, or any administrative unit of a political subdivision of the state." Id. § 63-46b-2(1)(b); Davis County,
The supreme court, however, seems to have consistently determined that it does not have original appellate jurisdiction over zoning cases under the catch-all provision found in section 78-2-2@)(J). Accordingly, this court must have jurisdiction. Examining section 78-22-83, the only provision that could apply is subsection 2(b)(Gi) which gives this court jurisdiction over "appeals from the district court review of adjudicative proceedings of agen- . cles of political subdivisions of the state or other local agencies...." Utah Code Amn. § (1996). As Payson City's counsel noted, however, this case does not arise from an "adjudicative" proceeding, but rather a legislative proceeding. Nevertheless, in order to effectuate the supreme court's order transferring these appeals to this court, "adjudicative" must be read broadly to include both administrative and legislative proceedings of state political subdivisions and local governments. Thus, read in conjunction with section 78-2-2, governing the supreme court's jurisdiction, section 78-2a-3(2)(b)0) confers original appellate jurisdiction to this court over this matter.
Id.
135 We agree with Payson City that the court of appeals' conclusion on this point is not consistent with a close reading of the statutory language. The jurisdiction of the court of appeals is defined by section 78-2a-3(2). When interpreting statutes, we look primarily to the statute's plain language. Hercules Inc. v. Utah State Tax Comm'n,
CONCLUSION
T36 Municipal land use decisions are presumed valid unless they are arbitrary and capricious. In this case, we reaffirm that whether a particular municipal land use decision is arbitrary and capricious depends upon whether the municipality has acted in a legislative, administrative, or quasi-judicial capacity. Legislative land use decisions are valid so long as they are reasonably debatable. Administrative and quasi-judicial decisions, however, continue to be subject to the substantial evidence test. Under the reasonably debatable standard, Payson City did not act arbitrarily and capriciously when it acted in a legislative capacity to deny the Plaintiffs' application to rezone their property.
T37 Additionally, we hold that the court of appeals does not have original jurisdiction to hear challenges to land use decisions by municipal governing bodies, and vacate the decision of the court of appeals.
Notes
. The court of appeals agreed with this interpretation of section 10-9-1001(3) in Harmon City, Inc. v. Draper City,
the 1991 enactment of section 10-9-1001(3), which largely codifies {municipal land use case law], did not alter the deferential review of a municipality's legislative zoning classification decisions under the arbitrary and capricious standard.
Id., § 14.
. Relying on its earlier decision in Harmon City,
. While we appreciate the court of appeals' valiant attempt to account for our transfer of this case to that court, we must observe that it overlooked another possible explanation: we incorrectly transferred it to them in the first place.
. The legislature might consider amending section 78-2a-3(2) to give the court of appeals original jurisdiction over municipal zoning decisions. This could be accomplished by amending section 78-2a-3(2), which currently gives the court of appeals original jurisdiction over "adjudicative proceedings of agencies of political subdivisions of the state or other local agencies" to give that court original jurisdiction over "proceedings of political subdivisions of the state or their agencies."
