Gonzales v. City of Atwater arose from a December 2010 collision at the intersection of Bellevue Road and Linden Avenue in Atwater, California, where Michelle Carrizales, while making a left turn, struck and killed pedestrian Delia Gonzales in the crosswalk. Delia’s family sued Carrizales and the City of Atwater for wrongful death, alleging that the intersection created a dangerous condition of public property. After trial, the jury found Carrizales not negligent, placed full fault on the City, and awarded more than $3.2 million in damages. The case then moved to the California Court of Appeal, where the City challenged the judgment and argued that the intersection design had been approved and therefore qualified for statutory design immunity.
On appeal, the court reversed the judgment against the City, holding that the City established design immunity under California Government Code section 830.6 and that the plaintiffs had not shown a loss of that immunity. The opinion focused on traffic engineering issues tied to the intersection’s approved design, including left-turn movement, lane arrangement, median and channelization features, and the sight conditions affecting drivers and pedestrians at Bellevue and Linden. The appellate ruling turned not on a new finding about who caused the collision, but on whether the City could be held liable for an approved roadway design that the court concluded remained protected under California law.
Before 2001, Bellevue Road moved through the intersection without signals, while Linden Street and the Kmart driveway were controlled by stop signs. In February 2001, Fehr & Peers completed a warrants study concluding that signalization was warranted at Bellevue and Linden based on interruption of continuous flow and four-hour volume. The appellate record also states that the City council approved moving the project forward in January 2001, though the opinion notes some uncertainty in the approval sequence because the final plans were signed later in May 2001.
Robert Rees of Fehr & Peers oversaw the signal design work, and the plans used permissive phasing for northbound Linden and southbound Kmart traffic, meaning left-turning drivers had to yield on green and turn when safe. Frank Lozano, the City’s civil engineer, reviewed the plans and approved them on May 4, 2001, after the City and Fehr & Peers completed their review process. At trial, Rees testified that he stood by the permissive phasing in the plans, while Lozano testified from his custom and practice that the plans were reasonable from an engineering standpoint and met or exceeded engineering standards.
After the signals were installed, two earlier fatalities occurred when drivers turning left from Linden onto Bellevue struck people traveling northbound in the crosswalk. The first was bicyclist John Toews in December 2002, and the second was pedestrian Winifred Dutton in August 2008. The appellate record states that this was the only signalized intersection in the City where pedestrian or bicyclist fatalities occurred in a crosswalk.
In response to congestion complaints, the City retained Wilbur Elias in February 2004 to prepare plans changing the signals from permissive phasing to split phasing. Elias testified that split phasing mainly addressed congestion, but that pedestrian safety could result as a by-product because it removed the conflict between northbound left-turning vehicles and pedestrians crossing Bellevue. Elias delivered the completed modification plans by August 2004, the City paid for the work, and the City never implemented the split-phase design.
On December 16, 2010, 73-year-old Delia Gonzales was crossing Bellevue from south to north in the marked crosswalk when Michelle Carrizales turned left from northbound Linden onto Bellevue and hit her. Carrizales told the officer at the scene that she never saw Gonzales. The collision became the central event in the later wrongful death case against both Carrizales and the City.
Gonzales’s husband and five adult children filed suit against Carrizales and the City in October 2011. They alleged Carrizales was negligent and that the City was liable for a dangerous condition of public property, including improper timing or phasing of the signals and failure to provide signage alerting drivers to pedestrians in the crosswalk. The pleadings placed the intersection’s design, signal timing, and pedestrian visibility at the center of the case.
After a multi-day jury trial, the jury found Carrizales not negligent and found the City solely liable. The jury awarded the plaintiffs $3,214,134 in damages. By that point, the case had turned on whether the intersection’s design and operation made the crossing unsafe, and the City’s post-trial effort focused on design immunity.
At trial, plaintiffs’ engineering expert Richard Ryan testified that he found no documentation explaining why permissive phasing had been chosen. He said he would have separated the left-turn phase from pedestrian movement because left-turning drivers often focus on oncoming traffic instead of pedestrians. He also said the engineer should have considered the nearby school, Kmart, residential area, T-intersection, and major roadway setting, though he did not say the 2001 plans were reasonable or unreasonable because he lacked enough information about the original decision-making process.
The City’s expert, James C. Jeffery III, disagreed. He testified that signal selection depends on engineering judgment guided by sources such as the MUTCD, and he opined that the conditions requiring a protected left-turn phase did not exist in 2010. In his view, there was nothing wrong with permissive phasing at that time.
The City argued that Government Code section 830.6 barred liability because the 2001 signal design had been approved in advance and was protected by design immunity. The trial court denied both the directed verdict request and the later motion for judgment notwithstanding the verdict, concluding that the case could proceed despite the immunity defense. That ruling set up the City’s appeal from the judgment and the order denying JNOV.
The California Court of Appeal reversed the judgment against the City and held that the City established design immunity as a matter of law. The court concluded that the approved 2001 signal plans caused the condition at issue, that the design received discretionary approval, and that the plaintiffs had conceded the plans were reasonable when adopted. The matter was remanded with directions to enter judgment in favor of the City, the damages award against the City did not stand, and the judgment in Carrizales’s favor remained in place because her liability could not be revisited in that appeal.

Plaintiff: Richard Ryan was identified in the appellate opinion as an engineering expert for the plaintiffs. He testified that he did not see documentation showing why permissive phasing had been selected for the intersection and said he would have separated the left-turn movement from the pedestrian crossing movement.
He also testified that the engineer should have evaluated site-specific conditions such as the nearby school, Kmart driveway, residential area, T-intersection, and major roadway setting before selecting the phasing approach. His contribution was limited to those opinions, and the opinion also notes that he did not say the 2001 plans were reasonable or unreasonable because he lacked enough information about the original decision-making process.
Defense: James C. Jeffery III was identified in the appellate opinion as an expert for the City. He testified that traffic-signal selection involves engineering judgment guided by standards such as the MUTCD and that the conditions requiring a protected left-turn phase were not present at the intersection in 2010. He also testified that there was nothing wrong with permissive phasing at that location at the time of the collision. His contribution, as described in the opinion, was to support the City’s position that the approved signal design remained acceptable.
A road design expert is often engaged in cases involving roadway layout, lane configuration, medians, channelization, and public-entity liability tied to approved plans. In a case like this, that expert would commonly review whether the claimed danger arose from the design itself, whether the built condition matched the approved plans, and how the roadway configuration affected vehicle and pedestrian movement.
An accident reconstruction expert is often engaged to analyze vehicle path, turning movement, impact sequence, timing, and scene evidence. In a case involving a left-turn collision with a pedestrian in a marked crosswalk, that expert would usually assess how the movement occurred, what could be seen during the turn, and whether the physical evidence matched the parties’ accounts.
A civil engineering expert is often engaged when a dispute concerns infrastructure design, municipal approval records, construction plans, or roadway safety features. In a case like this, that expert would typically review the intersection plans, related approvals, and whether the project conformed to accepted engineering practice at the time it was designed and installed.
For public-entity defendants, this case shows the value of proving each element of design immunity with approved plans, discretionary approval, and evidence that the plan was reasonable when adopted. The City’s position gained force because the record tied the claimed danger to an approved intersection design rather than to an unplanned field condition. In roadway cases involving traffic engineering, counsel should organize the approval history and design documents from the start.
The plaintiffs focused on signal phasing, pedestrian visibility, and the safety of the Bellevue-Linden intersection, but the appeal turned on whether those conditions flowed from an approved design protected by statute. That distinction matters because a dangerous-condition theory may fail if the record shows the challenged feature was part of a discretionary design decision. Attorneys should define early whether the case is really about approved roadway design, changed conditions, or operational failure.
The trial record included competing engineering opinions about permissive phasing, protected left-turn timing, and the site-specific features surrounding the crosswalk. The appellate opinion shows that expert testimony is most useful when it directly addresses the design decision, the available standards, and whether later conditions materially changed the safety picture. In a traffic engineering dispute, broad criticism is less effective than a tightly reasoned opinion tied to signal design, phasing, and documented decision-making.
The record included earlier pedestrian or bicyclist deaths at the same signalized intersection, which gave the plaintiffs factual support for arguing that the crossing was unsafe. Even so, prior incidents alone did not defeat the City’s defense because the appeal focused on statutory immunity and whether that protection had been lost. For attorneys, the lesson is that prior collisions can matter, but they must be framed in a way that fits the governing immunity and dangerous-condition rules.
The City continued to press design immunity through directed verdict and JNOV arguments, and that preserved the issue for appellate review. That strategy proved decisive when the Court of Appeal reversed the judgment and directed entry of judgment for the City. In intersection litigation involving signal phasing, lane arrangement, medians, and pedestrian crossing conditions, preserving those legal issues can be as important as winning factual disputes at trial.
Gonzales v. City of Atwater ended as a wrongful death case in which the plaintiffs obtained a jury verdict against the City, only to see that judgment reversed on appeal. The Court of Appeal held that the City established design immunity under California Government Code section 830.6 and directed entry of judgment in the City’s favor. As a result, the case stands as a careful reminder that even a large trial verdict may not survive when the challenged public-property condition is tied to an approved roadway design that remains protected under California law.
The case also shows why traffic engineering issues can become central in litigation over intersection safety, pedestrian crossings, signal phasing, lane arrangement, and sight conditions. In this record, the dispute turned on whether the Bellevue-Linden intersection’s approved design, including permissive left-turn operation and related roadway features, could support public-entity liability after a fatal crosswalk collision. For lawyers, public entities, and readers following roadway liability cases, the decision is a useful example of how design approval, engineering judgment, and the physical layout of an intersection can determine the final outcome on appeal.
What is Gonzales v. City of Atwater about?
Gonzales v. City of Atwater arose from a fatal 2010 pedestrian collision at the intersection of Bellevue Road and Linden Avenue in Atwater, California. The victim’s family sued both the driver and the City, alleging that the intersection created a dangerous condition of public property. The case later turned on whether the City could be held liable for an approved roadway design.
Why was the City of Atwater sued in this wrongful death case?
The plaintiffs alleged that the intersection’s signal phasing, pedestrian crossing conditions, and related roadway features made the location unsafe. Their theory was that those conditions contributed to the fatal crosswalk collision. That claim placed the intersection’s design and operation at the center of the case.
What did the jury decide in Gonzales v. City of Atwater?
The jury found that the driver was not negligent and placed full fault on the City of Atwater. It awarded the plaintiffs $3,214,134 in damages. At the trial stage, that meant the City was the only defendant held responsible for the loss.
Why did the Court of Appeal reverse the judgment against the City?
