Ordered that the order is affirmed, with one bill of costs.
In response to the defendants' assertions that they did not have notice of the condition which allegedly caused the plaintiff's fall, the plaintiff, proceeding under a theory of constructive notice, failed to raise a triable issue of fact as to whether the leaves or twigs upon which he allegedly slipped were visible and apparent for a sufficient length of time that, in the exercise of reasonable care, the defendants should have swept them (see, Gordon v. American Museum of Natural History, 67 N.Y.2d 836; Stoerzinger v. Big V Supermarkets, 188 A.D.2d 790; Paolucci v. First Natl. Supermarket Co., 178 A.D.2d 636). The expert opinion proffered by the plaintiff in opposition to the defendants' summary judgment motion is insufficient to raise a triable issue of fact. It was based, in part, upon information which was contradicted by the plaintiff himself, contained several opinions in the area of which the affiant's expertise was not established, and was speculative. Thus, the defendants were properly granted summary judgment.
In light of the foregoing, we need not reach the remaining issues raised by the plaintiff. Miller, J.P., Lawrence, Ritter and Santucci, JJ., concur.
