In 1970, the plaintiff Sidney F. Brown, Inc. (hereinafter Brown), purchased a parcel of land having an area of 24,516 square feet, located at the intersection of Long Hill Avenue and River Road in Shelton. The property was located in an R-3 residential zone, but at Brown’s request, the location was changed to a CB-2 business zone, in which a gasoline service station is a permitted use. In 1972, Brown leased the land to the plaintiff Chevron Oil Company.
The Brown property is bounded on the west by a narrow triangular-shaped parcel of land which is still zoned R-3, but which, because of its size, shape, and topography, cannot be used for residential building purposes. The Shelton zoning ordinance requires that any building in a business zone be set back forty feet from the boundary of a residence zone. The application of that setback requirement *148 to the Brown property, when taken in conjunction with front yard and side yard setback requirements, would restrict its usable area to only 3600 square feet.
On January 30,1973, Chevron filed an application with the defendant board of zoning appeals for a variance of the setback regulation from forty to twenty feet, and for certificates of approval for a gasoline station and for a limited repairer’s license. The board denied the application for the reasons that “the required variance in the setback line would not be in harmony with the purpose and intent of the ordinance”; that “such hardship as exists is of the applicant’s own making, inasmuch as he requested a zone change which now does not permit him to use the property as he now desires”; and that “the property could be used for a permitted use without variance.”
The plaintiffs appealed that decision to the Court of Common Pleas. That court, upon reviewing the record and the testimony presented to it, concluded that the reasons given by the board in denying the application lacked support in the record; that the application of the forty-foot setback regulation to the Brown property would be tantamount to confiscation ; and that the action of the board in denying the application was arbitrary, illegal, and in abuse of its discretion. The court then directed the board to grant the variance and the certificates of approval. After our grant of certification, the defendant took the present appeal, claiming that the court erred in reaching its conclusions and in ordering the relief that it did. 1

Housatonic Terminal Corporation
v.
Planning & Zoning Board,
The defendant first claims that the court erred in concluding that the record does not support the board’s determination that the variance would not be in harmony with the purpose and intent of the ordinance.

In testing that conclusion, we note that although the defendant’s appendix contains a statement made by the chairwoman of the board stating that the purpose of the forty-foot setback is to pro
*150
vide a buffer strip between a commercial and residential zone, the appendix is silent as to how that purpose would be frustrated by the granting of the present variance. On the other hand, the plaintiffs’ appendix contains evidence indicating that the triangular-shaped property which bounded the Brown property on the west was too small to be used for any residential purposes, and that there would always be a buffer strip of over forty feet between the Brown property and the nearest residence even if the variance were granted. Since there is an absence of any evidence calling for a conclusion contrary to that reached by the court, that conclusion must stand.
Parcesepe
v.
Zoning Board of Appeals,
The defendant next contends that the court erred in concluding that the board’s determination that the hardship was self-inflicted was unsupported. Although the property was rezoned from B-3 to CB-2 at Brown’s request in 1970, that is no reason to treat that land differently from other land similarly zoned and situated. The regulations permit the use of 35 percent of the area of any lot in a CB-2 zone. The application of the setback regulation to the Brown property, because of its location and shape, would restrict its use to less than 15 percent of its area. That restriction would apply to any permitted use of the property. The hardship here does not result from Brown’s successful request to change the zone in 1970; instead, it is solely caused by the application of the setback regulation to the unusually shaped subject property.

Garibaldi
v.
Zoning Board of Appeals,
*151
The defendant next argues that the court erred in concluding that the setback regulation, as applied to the subject parcel, was tantamount to confiscation. Zoning regulations, so far as they reasonably promote the public health, safety and welfare, are constitutional even though their effect may be to limit the exercise of private property rights.
Poneleit
v.
Dudas,
*152 There was no “practical confiscation” in the present ease, since a portion of the subject property could be used for some permitted use if the variance were not granted. The application of the setback regulation, however, would appropriate more than 85 percent of the property for the public welfare without payment of compensation. The extent of that deprivation must be considered in light of the evils which the regulation is designed to prevent. As already noted, the plaintiffs presented evidence to show that the buffer zone between business and residential property would be effectively maintained if the variance were granted. Moreover, the trial court concluded that the granting of the variance would not adversely affect the use and value of the residential land sought to be protected by the setback requirement, and the defendant has printed no evidence to refute that conclusion. In considering the “diminution in the value of the land,” the “degree of public harm to be prevented,” and the “alternatives available to the landowner,” the trial court concluded that the application of the setback requirement would be equivalent to confiscation. The record before us presents no circumstances which give us reason to upset that conclusion. 3
When a zoning board states the reasons for its action, “the question for the court to pass on is simply whether the reasons assigned are reasonably supported by the record and whether they are pertinent to the considerations which the commis
*153
sion is required to apply under the zoning regulations.”
DeMaria
v.
Planning & Zoning Commission,
Generally, when the court finds the action of an administrative agency to be illegal, it should go no further than to sustain the appeal.
Bogue
v.
Zoning Board of Appeals,
The defendant’s final claim is that the court improperly ordered the granting of the certificates of approval for a gasoline service station and a
*154
limited repairer’s license. Under §§ 14-321 and 14-322 of the General Statutes, the board acts as an agency of the state with authority to pass upon the suitability of the location for the purposes sought.
Atlantic Refining Co.
v.
Zoning Board of Appeals,
The record discloses that the board considered Chevron’s application in its entirety, and that it denied the certificates of approval. The reasons given for the denial of the application, however, related solely to the issue of the variance sought. Since those reasons would not support a denial of the certificates, the trial court correctly sustained the appeal with respect to them. As noted previously, however, the court may order the board to grant the certificates only if there was but a single conclusion which could reasonably be reached. Bogue v. Zoning Board of Appeals, supra. It cannot substitute its discretion for that of the zoning authority. In its appendix, the defendant has printed testimony to the effect that the building of a gasoline service station in the location described would cause a traffic problem and that it would constitute a hazard to various groups which met at a nearby fire station. It is thus by no means clear that the only reasonable conclusion that the board could *155 have reached was that the location was suitable for a gasoline station. The trial court erred in directing the hoard to grant the certificates.
There is error in part, the judgment is set aside and the case is remanded with direction to render judgment as on file except as to the application for certificates of approval for a gasoline station and limited repairer’s license, which application is to be returned to the zoning hoard of appeals for reconsideration in accordance with law.
In this opinion the other judges concurred.
Notes
The court made a limited finding with respect to testimony presented to it. The defendant has assigned error in the court’s failure to find certain facts set forth in the draft finding. The facts sought
*149
have not been shown to be admitted or undisputed, and the defendant has not shown how the court’s conclusions would be affected by their inclusion. See Practice Book § 628;
Schomer
v.
Shilepsky,
Section 8-6 of the General Statutes discloses the relevant circumstances to be taken into consideration by a zoning board of appeals when passing on an application for a variance. It provides in pertinent part: “The zoning board of appeals shall have the following powers and duties: ... (3) to determine and vary the application of the zoning bylaws, ordinances or regulations in harmony with their general purpose and intent and with due consideration for conserving the public health, safety, convenience, welfare and property values solely with respect to a parcel of land where, owing to conditions especially affecting such parcel but not affecting generally the district in which it is situated, a literal enforcement of such bylaws, ordinances or regulations would result in exceptional difficulty or unusual hardship . . . .”
Other courts have found virtual confiscation to occur where the application of setback regulations reduced the usable area of a lot to an unusually small size. 8 McQuillin, Municipal Corporations (3d Ed.) § 25.138; see, e.g.,
