*264 I
These two cases were tried together. The first, hereinafter referred to as the appeal, was-an appeal by the plaintiff from the refusal of the-planning and zoning commission of Madison, hereinafter referred to as the commission, to change,, from a residential to an industrial zone, the portion of the plaintiff’s property which extends north from the railroad for a distance of 300 feet.
The second case, hereinafter referred to as the action, was a suit for a declaratory judgment which the plaintiff instituted several months after the-appeаl, and during its pendency. The action was brought against the commission and the town of Madison and sought a judgment declaring that the-zoning regulations were illegal and void as to the plaintiff’s property and also injunctive relief against the enforcement of the zoning regulation placing the plaintiff’s property in a residential zone.. This relief was claimed on the ground that the residential zoning classification, from its inception in 1953 and up to and including the present time, continuously has been, and still is, as to this plaintiff, illegal and void as being in violation of the fourteenth amendment to the constitution of the United States as a taking of the plaintiff’s property without due process of law.
In each case, a decision adverse to the plaintiff was rendered and an appeal taken to this court. Although separate records and briefs were filed, the appeals were argued together in this court. We first consider the appeal.
II
The plaintiff is a large concern, with its maim plant in New Haven, primarily engaged in the busi *265 ness of selling lumber and building materials. In 1927, it established a branch plant in Madison on a tract of land of about four acres bounded on the south by the railroad, from which a spur track was built, and on the north by the Boston Post Road. In conducting its business, it stored lumber and building materials in sheds and out of doors, engaged in sawing and other lumber processing activities, and maintained a salesroom on the Boston Post Road.
This general section of Madison is cаlled the East River section and was first zoned in 1953. Property north of the railroad, including that of the plaintiff, was placed in residential zones, but property south of the railroad was placed in the light industrial zone, which is the least restrictive zone in Madison.
The plaintiff has operated its business successfully since 1953 as a nonconforming use. On June 27, 1961, it made application to the commission for an extension of the light industrial zone in a northerly direction from the railroad for a distance of 300 feet. The effect of this extension, if it had been granted, would be to place in the light industrial zone thе portion of the plaintiff’s property which was within 300 feet of the railroad and northerly of it. In other words, a light industrial spur of land would be extended into the residential zones. See cases such as
Woodford
v.
Zoning Commission,
The plaintiff gave two main reasons for seeking the change of zone. The first and primary reason was that, although the business was in a sound and prosperous condition, the plaintiff needed liquid assets and had decided to include the Madison property in a mortgage covering substantially all of its real estate, and it had found that lending institutions would not accept large mortgages on industrial property operating as a nonconforming use. Consequently, in order to realize the full value of the Madison property as mortgage security, the plaintiff claimed that the property must be placed in a light industrial zone. The second reason was that the plaintiff wished to be free to enlarge upon or change its present operations, especiаlly in the area of the manufacture and sale of prefabricated sections of buildings in accordance with a modern trend in the industry, and such an enlargement or change might be prohibited under the zoning regulations as an extension or change of a nonconforming use. See cases such as
Guilford
v.
Landon,
The commission gave four reasons for denying the zone change. As far as the reasons themselves are concerned, if any one of them supports the action of the commission, the plaintiff must fail in its appeal.
Senior
v.
Zoning Commission,
Another reаson given by the commission was that raised by most of the objectors, that is, that to grant the change would throw open the rezoned property to the most objectionable uses permissible in Madison.
Woodford
v.
Zoning Commission,
The real claim of the plaintiff before the commission was that, at the inception of zoning, its property was actually devoted to an industrial use by a prosperous, going concern, and that consequently the zoning regulations, in order to be reasonable and valid, should have zoned the property in аccordance with that use, since otherwise the property would be depreciated in value as a nonconforming use not subject to business expansion through enlargement or the adoption of improved manufacturing proc
*268
esses. The mere statement of the proposition is a demonstration of its invalidity. In a town such as Madison, which has grown through a long period of years, numerous nonresidential uses can usually be found in the old residential sections. They could be found in Madison along the Boston Post Road, as pointed out by the plaintiff. Since 1953, presumably Tn reliance on the zoning classification, numerous residences have been built near the plaintiff’s property in the residential zones. Under the plaintiff’s theory, a series of small, disconnected zones should have been created, each of a character such as to conform to the existing use at the inception of zoning, at least if that use involved a going commercial enterprise. Such a system would amount to establishing zones in accordance with actual, existing individual property uses and would be contrary to any permissible comprehensive plan.
State
v.
Huntington,
The commission’s denial of the application for a change of zone was a reasonable, if not the only reasonable, action permissible under the faсts as presented to the commission. This determination would be dispositive of these proceedings adversely to the contentions of the plaintiff were it not for the procedural problems into which the plaintiff has plunged this litigation by the institution of the action.
Ill
No hint of any claim that the zoning classification, as applied to the plaintiff’s property, was so con *269 fiscatory as to be unconstitutional was given the commission at the hearing before it. Nor was any such claim raised in the pleadings incident to the appeal taken to the Court of Common Pleas. Only long afterwards, upon the institution of the action, was unconstitutionality first claimed.
It is difficult to conceive of a stronger reason for the commission’s granting the request for a change of zone than proof that the existing zoning classification, in its effect on the plaintiff’s land, was so arbitrary and unreasonable as to be confiscatory. See
Del Buono
v.
Board of Zoning Appeals,
*270
Indeed, it is open to serious question whether as matter of law the plaintiff would be entitled either to a declaratory judgment or to ancillary injunctive relief in the face of the apparently adequate remedy open to it of including the foregoing claim both in its application for a change of zоne and in its appeal from the commission’s refusal to grant that change.
Holt
v.
Wissinger,
But even if a declaratory judgment action had been appropriate, the instant action was inadequate for lack of any order of notice, at least to owners of residence properties who would be adversely affected by the granting of the plaintiff’s claims for relief.

v.
Toquet,
We have decided, however, without in any way condoning or approving its institution, or even its adequacy as matter of law, to take the action as treated by the parties and the court below and briefly to consider the constitutional claim therein raised.
Anselmo
v.
Cox,
The burden of proving the unconstitutionality of a legislative enactment, even though of local origin, is not a light one. Of course, the value of thе plaintiff’s property would almost certainly be enhanced by placing it in an industrial zone where it would be available for the most objectionable uses permis
*272
sible in Madison. This would also be true of any other nonconforming industrial use in a residential zone. But such a fact would not justify overthrowing thе commission’s zonal classification as unconstitutional. The maximum possible enrichment of a particular landowner is not a controlling purpose of zoning.
Senior
v.
Zoning Commission,
There is no error in either case.
In this opinion the other judges concurred.
Notes

Florentine
v.
Darien,
The appeal, of course, was merely an attaсk on the zoning classification given the plaintiff’s particular property. It was not an attack on the ordinance as a whole. The plaintiff, by appealing, would not have adopted a position inconsistent with its claim of unconstitutionality.
