Summary judgment is appropriate when there is no genuine issue as to any material fact and either party is entitled to judgment as a matter of law. N.C.R. Civ. P. 56. Here, there is no substantial controversy over the facts. The controversy is about the legal significance of those facts. Determining the validity of the ordinance enacted by the Columbus Board is, therefore, a proper case for summary judgment. See Blades v. City of Raleigh, 280 N.C. 531, 187 S.E.2d 35 (1972).
The authority to enact zoning legislation is incorporated in N.C. Gen. Stat. § 160A-381 (1987). In addition, the Columbus Board has the authority to rezone property “when reasonably necessary to do so in the interests of the public health, the public safety, the public morals or the public welfare. Ordinarily, the only limitation upon this legislative authority is that it may not be exercised arbitrarily or capriciously.” Allred v. City of Raleigh, 277 N.C. 530, 545, 178 S.E.2d 432, 440 (1970).
[1] Plaintiffs first contend the Board acted arbitrarily and capriciously in that the July rezoning ordinance constituted illegal “spot zoning.” Spot zoning has been defined as follows:
[a] zoning ordinance, or amendment, which singles out and reclassifies a relatively small tract owned by a single person and surrounded by a much larger area uniformly zoned ... so as to relieve the small tract from restrictions to which the rest of the area is subjected. ... It is beyond the authority of the municipality, in the absence of a clear showing of a reasonable basis for such distinction.
Blades, 280 N.C. at 549, 187 S.E.2d at 45. Although not every case of spot zoning is illegal, Chrismon v. Guilford County, 322 N.C. 611, 627, 370 S.E.2d 579, 588 (1988), we fail to see any interpretation of the facts that would render the proposed rezoning here a case of spot zoning. The small tract rezoned Highway Commercial is not surrounded by a much larger uniformly zoned area. The property is bounded by a R-2 Residential district only on the north and east (and a small pie shaped sliver of land on the west). On the south it faces a major highway and across that road, the land is zoned Public Service. At its southwest corner, the tract touches a Highway Commercial district and a city boundary. *339Across that boundary is a county Highway Commercial district. This assignment of error is overruled.
Plaintiffs make a related argument based upon their erroneous belief that the action constituted spot zoning. As our Supreme Court has noted, “the true vice of illegal spot zoning is in its inevitable effect of granting a discriminatory benefit to one landowner and a corresponding detriment to the neighbors or the community without adequate public advantage or justification.” Chrismon, 322 N.C. at 628-29, 370 S.E.2d at 589. Plaintiffs argue that the action by the Board only benefits the individual landowner, causes irreparable damage to the surrounding property owners and has a detrimental impact on the entire community. We disagree.
The property rezoned here borders on the main east-west thoroughfare through Columbus. The record is clear that the Board discussed the negative effects of highway traffic on any residential property along the road. The Board reviewed the commercial nature of the remainder of Highway 108 and the town’s comprehensive plan of commercial development along the highway. It also discussed the possible benefits of increasing the town’s tax base and providing more jobs through the establishment of more commercial enterprises. No evidence supports plaintiffs’ contention that the sole purpose of the Board’s action was to benefit the landowner or that only the landowner would profit by the rezoning at the expense of the greater community.
[2] Finally, plaintiffs contend that the action by the Board constituted “contract zoning.”' “Illegal contract zoning properly connotes a transaction wherein both the landowner who is seeking a certain zoning action and the zoning authority itself undertake reciprocal obligations in the context of a bilateral contract.” Chrismon, 322 N.C. at 635, 370 S.E.2d at 593; see Allred, 277 N.C. 530, 178 S.E.2d 432, and Blades, 280 N.C. 531, 187 S.E.2d 35. Plaintiffs argue that in the original rezoning request the landowner assured the zoning authorities that the property would be used only for an automobile dealership. They contend any activity of the Board “would necessarily have been based upon the assumption that this was the use to which the property would be subjected,” and that this reciprocal understanding resulted in a tacit agreement which constituted contract zoning.
The illegal aspect of contract zoning occurs when a zoning authority binds itself to enact a zoning amendment and agrees *340not to alter the zoning change for a specified period of time. Chrismon, 322 N.C. at 635, 370 S.E.2d at 593 (citing Shapiro, The Case for Conditional Zoning, 41 Temp. L.Q. 267, 269 (1968)). When a zoning authority takes such a step and curtails its independent legislative power, it has acted ultra vires and the rezoning is therefore a nullity. Id.
We find no evidence of any reciprocal agreement made between the Board and the current owner, the applicant who filed for rezoning, or with anyone else concerning the property. The transcript is unequivocal that the Board understood that if the property was rezoned, the owner was not bound to operate an automobile dealership or any other specific establishment on the tract. The record is also clear that the Board was advised of all the possible uses that could be made in a Highway Commercial district and of the possible uses if the property remained R-2 Residential. After comparing the two alternatives, the Board made the decision to rezone.
[3] Furthermore, all the proper rezoning procedures were followed in this case. See Chrismon, 322 N.C. at 636, 370 S.E.2d at 593. Initially, the proposed change was referred to the Town Planning and Zoning Board, which endorsed the change. A public hearing was held, and at a separate public meeting, the Board unanimously adopted the zoning change. There is no indication that the Board’s decision was a foregone conclusion or that the decision-making procedures were a ploy to cover up a hidden agreement between the landowner and the zoning authority. Plaintiffs’ argument that the Board’s knowledge of the landowner’s intended use may have influenced their decision is not sufficient to support an allegation that contract zoning occurred. This assignment of error is overruled, and the order of the trial court is therefore
Affirmed.
Judges Eagles and Parker concur.
