Public Street Utility-Vault Grate Gaps: Google Street Imagery, Competing Experts, and the Limits of “Trivial Defect” and “Open and Obvious” on Summary Judgment

Introduction

Stegman v City of Glens Falls, N.Y. (2026 NY Slip Op 03486 [3d Dept June 4, 2026]) arises from a bicycle accident on Maple Street in Glens Falls. Plaintiff James Stegman alleged that his front wheel became trapped in a narrow but deep gap running along the perimeter of a metal grate embedded in the travel lane. The grate covered “Vault 87,” an underground utility vault owned by Niagara Mohawk Power Corporation d/b/a National Grid (“National Grid”).

Plaintiffs sued both the City of Glens Falls and National Grid, but later discontinued as against the City. The litigation then centered on whether National Grid could be held liable for an alleged roadway defect adjacent to its vault structure.

The key issues on appeal were whether National Grid was entitled to summary judgment on the grounds that: (1) the condition was not defective/dangerous (or was reasonably designed), (2) it lacked notice, (3) the defect was trivial and nonactionable, and (4) the condition was open and obvious and not inherently dangerous.

Summary of the Opinion

The Third Department modified Supreme Court’s order. While it agreed that plaintiffs failed to raise a triable issue of actual notice, it held that triable issues existed as to:

  • whether the gap constituted a defective/dangerous condition (given dueling expert opinions and a disputed schematic interpretation),
  • whether National Grid had constructive notice (including through long-visible conditions shown in Google Maps imagery),
  • whether the condition was trivial under Hutchinson v Sheridan Hill House Corp., and
  • whether “open and obvious” and “not inherently dangerous” could be resolved as a matter of law on this record.

The court therefore reversed the grant of summary judgment to National Grid and denied its motion, allowing plaintiffs’ claims to proceed.

Analysis

Precedents Cited (and How They Shaped the Ruling)

1) Summary judgment framework and burden shifting

  • Levitt v Tops Mkts., LLC (240 AD3d 973 [3d Dept 2025]) and Marra v Zaichenko (214 AD3d 1165 [3d Dept 2023]) supplied the baseline premises-liability rule invoked by the court: on summary judgment, the defendant must show reasonable safety and lack of creation/notice of the dangerous condition.
  • Alvarez v Prospect Hosp. (68 NY2d 320 [1986]) and Zibro v Saratoga Natl. Golf Club, Inc. (55 AD3d 998 [3d Dept 2008]) were used for the familiar burden shift: once National Grid made a prima facie showing, plaintiffs had to produce admissible proof creating material fact disputes.

2) Competing expert proof as a triable-issue generator

  • McKee v State of New York (75 AD3d 893 [3d Dept 2010]) was cited in connection with the defense expert’s reliance on “analogous” standards and the broader proposition that engineering/design evidence and standards can be relevant to whether a condition is defective.
  • Schrader v Nichols (198 AD3d 1153 [3d Dept 2021]) and Castellanos v 57-115 Assoc., L.P. (211 AD3d 459 [1st Dept 2022]) supported the court’s conclusion that dueling expert submissions typically create triable issues that cannot be resolved on summary judgment.
  • In the footnote, Admiral Ins. Co. v Joy Contrs., Inc. (19 NY3d 448 [2012]) and Dobco, Inc. v Facilities Dev. Corp. (263 AD2d 592 [3d Dept 1999]) were invoked to emphasize that credibility and interpretive disputes—here, what a “¼-inch” notation in a 2003 schematic meant—are not for summary judgment resolution.

3) Notice doctrine: actual vs. constructive

  • Carpenter v J. Giardino, LLC (81 AD3d 1231 [3d Dept 2011], lv denied 17 NY3d 710 [2011]) supported the holding that an absence of prior incident reports can establish lack of actual notice as a matter of law when plaintiffs do not counter with admissible proof.
  • Hagin v Sears, Roebuck & Co. (61 AD3d 1264 [3d Dept 2009]) provided the constructive notice standard: the condition must be visible/apparent and exist long enough to permit discovery and correction.
  • Raczes v Horne (68 AD3d 1521 [3d Dept 2009]) supported the defendant’s prima facie constructive-notice showing through evidence of inspections not noting the issue.
  • Gray v State of New York (159 AD3d 1166 [3d Dept 2018]), Hockenberry v Mehlman (93 AD3d 915 [3d Dept 2012]), and McKee v State of New York (75 AD3d at 895) were used in a comparative sense to show that this record—especially the Google Maps imagery and testimony about what would have been done if observed—was sufficient to create a fact question on constructive notice.

4) Trivial defect doctrine

  • Hutchinson v Sheridan Hill House Corp. (26 NY3d 66 [2015]) controlled: the defendant must show the defect is physically insignificant and that the context does not magnify the risk.
  • Bovee v Posinewski Enters., Inc. (206 AD3d 1112 [3d Dept 2022]) reinforced the application of Hutchinson at the Appellate Division level.
  • Gami v Cornell Univ. (162 AD3d 1441 [3d Dept 2018], lv denied 32 NY3d 916 [2019]) was cited for the proposition that where circumstances could elevate risk, triviality cannot be declared as a matter of law.

5) Open and obvious; inherent danger; jury questions

  • Osterhoudt v Acme Mkts., Inc. (214 AD3d 1181 [3d Dept 2023]) supplied the key doctrinal point emphasized by the court: “open and obvious” does not automatically defeat liability; it affects foreseeability and comparative negligence.
  • Santiago v National Grid USA Serv. Co., Inc. (235 AD3d 1204 [3d Dept 2025]) and Streit v Katrine Apts. Assoc., Inc. (212 AD3d 957 [3d Dept 2023]) supported the rule that open-and-obvious determinations usually belong to the jury and must be assessed in context.
  • Catman v Back Water Grille LLC (225 AD3d 966 [3d Dept 2024]) and Wolfe v Staples, Inc. (224 AD3d 1126 [3d Dept 2024]) reinforced that visibility and inherent-danger questions often cannot be resolved as a matter of law when surrounding circumstances are disputed.

6) Bicycle roadway use and foreseeability

  • The court referenced Vehicle and Traffic Law § 1231 and Felix v Polakoff (178 AD3d 561 [1st Dept 2019]) to rebut the defense expert’s suggestion that Stegman’s bicycling on Maple Street was “unauthorized,” and to frame bicycle use of the roadway as legally contemplated—relevant to both the dangerousness analysis and the risk context for triviality and open/obvious issues.

Legal Reasoning

1) Defect/dangerous condition: design intent is not dispositive where standards and measurements are disputed

National Grid’s expert characterized the gap as part of a 1964 design to permit thermal expansion and asserted that analogous standards supported its safety. This satisfied the prima facie burden on defect/danger. But plaintiffs countered with expert proof that (a) the 1¼-inch width violated applicable standards/regulations, (b) roadway bicycle use is contemplated by law, and (c) a 2003 schematic could be read as specifying a ¼-inch perimeter gap—suggesting the existing 1¼-inch gap may represent deterioration, displacement, or an out-of-tolerance condition rather than a benign design feature.

The court treated the clash as a classic summary-judgment problem: where expert opinions and technical document interpretations conflict, the factfinder must decide credibility, meaning, and weight.

2) Notice: inspection evidence helps a defendant, but long-visible conditions and testimony about repair practices can restore a triable issue

On actual notice, the court accepted National Grid’s lack-of-prior-incident showing and held plaintiffs did not raise a triable issue.

On constructive notice, however, the court emphasized context-specific proof: a National Grid employee testified that if the gap had been observed, it would have been scheduled to be filled/leveled (e.g., to avoid snowplow impacts), implying the condition was one National Grid treated as correctable when seen. Plaintiffs then offered Google Maps images (2015 and 2019) showing the gap as visible and apparently unchanged through the 2020 accident, plus expert affirmation that the imagery matched post-accident photos. This combination supported an inference that the condition was visible and apparent long enough that it could have been discovered and corrected.

Notably, the court did not hold that Google Maps imagery proves constructive notice; rather, it held the imagery, together with other testimony and comparisons, was sufficient to create a fact issue.

3) Trivial defect: size matters, but so do configuration and use context

Although the 1¼-inch width could favor a triviality finding, the court focused on factors that could magnify risk: the gap’s substantial length (38½ inches), its placement within a travel lane shared with motor vehicles, and its orientation parallel to the direction of travel—features that could increase the likelihood of a bicycle wheel tracking into and being captured by the gap. The court also credited evidence that bicyclists necessarily use streets like Maple Street to reach dedicated trails, supporting foreseeability of bicycle encounters with roadway features like this.

Under Hutchinson v Sheridan Hill House Corp., those circumstances prevented National Grid from establishing triviality as a matter of law.

4) Open and obvious: not a complete defense; usually a comparative-negligence and foreseeability question

Supreme Court had treated “open and obvious” and “not inherently dangerous” as dispositive. The Third Department corrected that approach: visibility does not automatically eliminate liability; it generally bears on foreseeability and comparative fault. The court stressed that the inquiry must incorporate surrounding circumstances—here, the traffic light change ahead, a moving vehicle to Stegman’s left, and parked cars to his right. On that record, a jury could find the gap not readily observable in the practical riding environment, and/or could find it inherently dangerous to bicyclists even if technically visible in isolation.

Impact

  • Utilities and vault owners face heightened trial risk where roadway-adjacent structures create narrow, wheel-trapping gaps. The decision underscores that “design feature” defenses do not end the case when plaintiffs can point to differing standards, later schematics, measurement discrepancies, or changes over time.
  • Publicly available street imagery can be meaningful constructive-notice evidence. The court’s acceptance of Google Maps images as part of a triable-issue record is likely to encourage litigants to use time-stamped imagery to show long duration and visibility—particularly in defect cases involving fixed infrastructure.
  • Trivial defect analysis will be more context-sensitive for bicycle-related roadway incidents. Even small dimensions may be nontrivial where geometry (length/orientation), placement (travel lane), and mode-specific risk (bicycle wheel capture) elevate danger.
  • “Open and obvious” remains a limited tool on summary judgment. This opinion reinforces the Third Department’s line that open-and-obvious arguments commonly go to comparative negligence and foreseeability rather than serving as a categorical bar, especially where traffic and attentional demands are part of the surrounding circumstances.

Complex Concepts Simplified

  • Summary judgment: A pretrial ruling where the court ends a claim if no real factual disputes exist and one side is entitled to win as a matter of law. If experts or evidence meaningfully conflict, summary judgment is typically denied.
  • Prima facie burden / burden shifting: The moving party must first make an initial showing. If it does, the opposing party must respond with admissible evidence creating a genuine factual dispute.
  • Actual notice vs. constructive notice:
    • Actual notice means the defendant actually knew of the specific hazard (e.g., a prior complaint or report).
    • Constructive notice means the hazard was visible and existed long enough that the defendant should have discovered it through reasonable inspection.
  • Trivial defect doctrine: Some minor defects are too insignificant to be actionable. But courts consider not only size, but location, lighting, traffic patterns, configuration, and how people reasonably use the area.
  • Open and obvious: Even if a hazard could be seen, that usually does not end the case; it may reduce the plaintiff’s recovery via comparative negligence or affect the foreseeability analysis.
  • Comparative negligence: Fault can be divided. A plaintiff’s inattention or choices may reduce damages, but do not necessarily eliminate liability.

Conclusion

Stegman v City of Glens Falls, N.Y. reinforces a practical, fact-intensive approach to roadway defect claims involving utility infrastructure. The Third Department held that (1) dueling experts and disputed technical documents can preclude summary judgment on defect/danger, (2) long-visible conditions supported by Google Maps imagery can create a constructive-notice triable issue even where inspection records exist, and (3) neither trivial defect nor open-and-obvious theories should be applied mechanically—especially where configuration, location in a travel lane, and bicycle wheel-capture risk could elevate danger. The opinion’s broader significance lies in its insistence that context, mode of travel, and real-world attentional demands often make these questions ones for a jury rather than for summary disposition.
