60 Cal.App.5th 423
Cal. Ct. App.2021Background
- In March 2016 Jonathan Tansavatdi, a bicyclist, was killed in Rancho Palos Verdes when his bicycle collided with a right‑turning truck at Hawthorne Blvd. and Vallon Dr.; that road segment lacked a bicycle lane while other stretches had them.
- Betty Tansavatdi sued the City under Gov. Code §835 for a dangerous condition of public property, alleging the City created (or allowed) the dangerous condition by omitting/removing a bike lane and also failed to warn of the hazard.
- The City moved for summary judgment asserting design immunity under Gov. Code §830.6, relying on signed 2009 resurfacing plans that did not include a bike lane for the relevant segment; the plans were signed "APPROVED" by the Director of Public Works, Jim Bell.
- The City submitted engineering testimony that the plans complied with guidelines and the intersection had an excellent collision record; plaintiff submitted a traffic expert opining the absence of a bike lane rendered the location dangerous and that warnings/guidance were needed.
- The trial court granted summary judgment on design immunity without addressing the failure‑to‑warn theory; on appeal the court affirmed design immunity as to the omitted bike lane but vacated in part and remanded for the trial court to consider plaintiff’s failure‑to‑warn claim.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the City established design immunity for the absence of a bicycle lane | Tansavatdi: City failed to prove (a) the omission was caused by a plan/design, (b) the plans were approved by an authorized decisionmaker, and (c) substantial evidence shows the plans were reasonable. | City: 2009 resurfacing plans omitted the bike lane at the segment; plans bear Director Bell’s "APPROVED" signature showing discretionary approval; experts show the design is reasonable. | Design immunity applies: undisputed causal link to the 2009 plans; Bell’s signed approval established discretionary approval as a matter of law; substantial evidence (expert declarations) supported reasonableness. |
| Whether design immunity bars plaintiff’s failure‑to‑warn claim | Tansavatdi: Even if immunity applies to the design omission, the City may still be liable for an independent negligent failure to warn (a concealed trap). | City: Design immunity covers the condition and precludes liability for failure to warn; no separate duty. | Design immunity does not categorically bar an independent negligent failure‑to‑warn claim (Cameron). The case is remanded for the trial court to consider the failure‑to‑warn theory; but a failure‑to‑warn that is merely the absence of the design itself is not actionable where immunity applies. |
