ORDERED that the order is affirmed, with one bill of costs to the respondents appearing separately and filing separate briefs.

The plaintiffs commenced this action against, among others, John and Rosemarie Monteforte (hereinafter the Montefortes) and the County of Nassau (hereinafter the County), for injuries sustained by the plaintiff Steve Harvey when he tripped and fell over a sidewalk allegedly raised by overgrown tree roots. The Montefortes, who are the abutting landowners, and the County separately moved for summary judgment dismissing the complaint insofar as asserted against them. The County argued that it had not received prior written notice of the alleged sidewalk defect (see, Nassau County Administrative Code § 12-4.0[e]). In response, the plaintiffs moved to stay determination of the motions and to compel the deposition of the County's horticulturist, who was responsible for tree maintenance and maintained records to that effect. The Supreme Court denied the plaintiffs' motion and granted summary judgment to the Montefortes and the County. This appeal ensued.

The plaintiffs' only argument on appeal is that the Supreme Court erred in deciding the issue of summary judgment without compelling the County to produce its horticulturist for an examination before trial. We disagree.

The plaintiffs do not allege that the County had prior written notice of the sidewalk defect. Rather, they contend that deposing the County's horticulturist will show that the County had actual notice of the sidewalk defect, thus obviating their need to comply with the County's prior written notice provision. However, actual notice is not an exception to the prior written notice requirement (see, Poirier v. City of Schenectady, 85 N.Y.2d 310, 314; Passaro v. City of Newburgh, 272 A.D.2d 385, 386; Sorrento v. Duff, 261 A.D.2d 919; Berlowitz v. Town of Brighton, 259 A.D.2d 983; Deans v. City of Buffalo, 181 A.D.2d 1015). Moreover, the horticulturist's deposition will not help the plaintiffs establish the applicability of either of the only two recognized exceptions to the County's prior written notice requirement, namely, a defect created by the County or a special use conferring a special benefit on the County (see, Amabile v. City of Buffalo, 93 N.Y.2d 471, 474). Thus, the plaintiffs have failed to establish that the horticulturist's deposition is material and necessary to the prosecution of their case (see, Amanatides v. City of New York, 234 A.D.2d 490), and the Supreme Court properly denied the plaintiffs' motion to stay determination of the motions for summary judgment until further discovery was completed.
