PER CURIAM.

By complaint dated July 29, 1977, the plaintiffs appealed to the Court of Common Pleas from the granting of a subdivision application of the defendant Avon Mountain Estates, Inc., by the defendant planning and Zoning commission (hereinafter the commission). The plaintiffs are residents of the town of Avon and own property which abuts the defendant's property. In their appeal, the plaintiffs claimed to be aggrieved by the decision of the commission, in that the subdivision "provides a drainage system that will aggravate . . . erosion problems . . . and will greatly increase vehicular traffic and alter established traffic patterns in the area . . . [and] lessen the property values of the plaintiffs' premises." The Court of Common Pleas took evidence limited to the question of aggrievement and, in its limited finding, determined that the plaintiffs had failed to carry their burden of showing specific facts demonstrating aggrievement, and dismissed the plaintiffs' appeal. The court found further that even if aggrievement were established, the action of the commission in approving the defendant's subdivision application was not illegal, arbitrary or in abuse of discretion. Since we find no error in the court's finding or judgment with respect to the plaintiffs' inability to demonstrate aggrievement, we need not address the second ground of the court's decision.

The finding of the Court of Common Pleas that the plaintiffs were not aggrieved by the commissioner's action will not be disturbed on appeal unless the subordinate facts found do not support that finding. Fletcher v. Planning Zoning Commission, 158 Conn. 497, 503, 264 A.2d 566. A review of the finding discloses that the testimony of the plaintiffs Edwart Walls and Elizabeth Brucker at the hearing as to their "aggrievement" related only to issues of traffic. They expressed "concern," "fear" and "apprehension" that the subdivision approval might result in increased traffic; no specific evidence was offered, however, to support those fears. The court found that the unsubstantiated fears of the plaintiffs did not establish aggrievement, and concluded that "the plaintiffs failed to show that they had a specific, personal and legal interest in the subject matter of the decision, as distinguished from a general interest such as is the concern of all members of the community, and that they were specifically and injuriously affected in their property or other legal rights."

We have only recently had occasion to reaffirm the criteria by which the question of aggrievement is to be determined. "Review of an action of a planning and zoning agency exists only under statutory authority. Schwartz v. Town Plan Zoning Commission, 168 Conn. 20, 25, 357 A.2d 495; Tazza v. Planning Zoning Commission, 164 Conn. 187, 191, 319 A.2d 393. General Statutes . . . [ 8-28] permit[s] appeals from a decision of a zoning commission only by one `aggrieved' by the contested decision." Bell v. Planning Zoning Commission, 174 Conn. 493, 495, 391 A.2d 154. Compliance with these provisions encompasses a well settled, twofold test: "`First, the party claiming aggrievement must successfully demonstrate a specific, personal and legal interest in the subject matter of the decision, as distinguished from a general interest, such as is the concern of all members of the community as a whole. Second, the party claiming aggrievement must successfully establish that this specific personal and legal interest has been specially and injuriously affected by the decision.' Cf. General Statutes 19-402; New Haven v. Public Utilities Commission, [ 165 Conn. 687, 700, 345 A.2d 563]; Sheridan v. Planning Board, 159 Conn. 1, 13, 266 A.2d 396; Johnson v. Zoning Board of Appeals, 156 Conn. 622, 623, 238 A.2d 413; Krejpcio v. Zoning Board of Appeals, 152 Conn. 657, 660, 211 A.2d 687." Beckish v. Manafort, 175 Conn. 415, 420, 399 A.2d 1274, quoting Nader v. Altermatt, 166 Conn. 43, 51, 347 A.2d 89.

It is a well established principle that mere generalizations and fears such as those about which the plaintiffs testified at the hearing do not establish aggrievement. Sheridan v. Planning Board, 159 Conn. 1, 14, 266 A.2d 396; Hughes v. Town Planning Zoning Commission, 156 Conn. 505, 508, 242 A.2d 705; Tucker v. Zoning Board of Appeals, 151 Conn. 510, 516, 199 A.2d 685; Joyce v. Zoning Board of Appeals, 150 Conn. 696, 698, 187 A.2d 239. Neither does the fact that the plaintiffs owned property abutting the proposed subdivision, in and of itself, establish aggrievement, See note 1, supra; Vose v. Planning Zoning Commission, 171 Conn. 480, 484-85, 370 A.2d 1026. None of the facts found by the court compels the conclusion that the plaintiffs were aggrieved by the decision of the commission. To the contrary, the facts found were adequate to support its conclusion that the plaintiffs were not aggrieved. Consequently, that conclusion cannot be disturbed. Parcesepe v. Zoning Board of Appeals, 154 Conn. 46, 47, 221 A.2d 270.

We find no error in the judgment of the court that the plaintiffs failed to carry their burden on the issue of aggrievement. Pleading and proof of aggrievement were prerequisites to the trial court's jurisdiction over the subject matter of the plaintiffs' appeal. Fletcher v. Planning Zoning Commission, 158 Conn. 497, 501, 264 A.2d 566; Hughes v. Town Planning Zoning Commission, 156 Conn. 505, 509, 242 A.2d 705. In the absence of such pleading and proof, the court properly dismissed the appeal.
