Real Parties in Interest.

In a first amended complaint, real parties in interest Guadalupe Castillo 

(Guadalupe)

1 and Juan Miguel Castillo (Juan) through his guardian ad litem, sued 

petitioner State of California Department of Transportation (Caltrans), Daniel Flores 

(Flores), and Kemira Water Solutions (Kemira). The causes of action against Caltrans 

were for dangerous condition of public property and loss of consortium. The trial court 

denied Caltrans’s motion for summary judgment. Caltrans petitioned this court for a 

writ of mandate directing the trial court to grant its motion. We issued an order to show 

cause why the relief should not be granted. We now grant the petition. 

FACTUAL AND PROCEDURAL HISTORY

A. FIRST AMENDED COMPLAINT

On June 17, 2016, at approximately 11:00 p.m., Juan was driving southbound on 

U.S. 395. Juan was driving a 2012 Toyota Corolla, and his wife, Guadalupe, was in the 

passenger seat. For approximately 10 miles, Juan was driving behind two or three cars, 

which were behind Kemira’s tanker truck that was driven by Flores. Kemira’s tanker 

truck was traveling at 40 or 50 miles per hour. That 10-mile portion of U.S. 395 is a 

two-lane highway without turnouts or passing lanes.

1

 We use first names for the sake of clarity; no disrespect is intended. 
3

Juan moved his car into the oncoming traffic lane in an attempt to accelerate past 

Kemira’s tanker truck. Juan saw an oncoming northbound vehicle, swerved out of the 

way, lost control of his car, collided with Kemira’s tanker truck, and his car was crushed 

beneath the tanker truck. The accident occurred south of Kraemer Junction, 

approximately two and one-half miles north of Macon Road. Due to the crash, Juan is 

in a permanent vegetative state and Guadalupe suffered a traumatic brain injury and 

multiple fractured bones. Juan was an aeronautics engineer and Guadalupe was a 

registered nurse.

In the dangerous condition of public property cause of action, Juan and 

Guadalupe (collectively, the Castillos) alleged Caltrans created a dangerous condition 

by not having passing lanes or turnouts for 10 miles, which meant “drivers are forced to 

overtake vehicles by driving into the dangerous oncoming flow of highway traffic . . . 

through a broken yellow line between the oncoming traffic lanes on the portion of US395 where the accident occurred.” The Castillos asserted the dangerous condition was a 

substantial factor in causing their injuries. The Castillos sought general and special 

damages.

B. MOTION FOR SUMMARY JUDGMENT

Caltrans moved for summary judgment arguing that it had design immunity 

(Gov. Code, § 830.6). Caltrans contended the crash occurred “at or about post mile 

35.96,” where the speed limit is 65 miles per hour. In 2010, Caltrans added centerline 

rumble strips and restriped the area where the crash occurred (the subject location). In 

the 2010 restriping plans, no passing zones were specifically designated for striping 
4

purposes. Postmiles 33.58 to 36.71 were not designated as no passing zones. The 2010 

restriping plans were approved by Chris Hardimon (Hardimon), a registered civil 

engineer. Caltrans submitted the declaration of Christian Engelmann (Engelmann), a 

registered civil engineer and former Caltrans employee. Engelmann examined the 

subject location as well as design plans for the subject location and opined that the 

striping that allowed for passing was reasonable. 

C. OPPOSITION

In opposing the motion for summary judgment, the Castillos asserted design 

immunity did not apply because roadway striping is an operations issue, not a design 

issue. Alternatively, if striping is a design issue, then the Castillos asserted Caltrans 

failed to provide substantial evidence that the design was reasonable because Caltrans’s 

expert, Engelmann, based his opinions on an area that was not the crash site. The 

Castillos asserted the crash occurred near postmile 36.13, which is approximately 1,000 

feet from the location examined by Engelmann. Additionally, the Castillos asserted the 

design did not meet the sight distance standards for passing set forth in the Highway 

Design Manual (HDM).

Next, the Castillos contended that, if Caltrans proved it had design immunity, 

then Caltrans lost that immunity. The Castillos asserted that, in 2014, the southbound 

passing lane north of the subject location was removed, which constituted a physical 

change. The Castillos contended that physical change rendered the design dangerous 

because the subject location allowed for passing but “it failed to meet the sight-distance 

requirements for a passing zone.” The Castillos’ expert, Dale R. Dunlap (Dunlap), a 
5

registered civil engineer, described two reports that raised concerns regarding crosscenterline crashes on U.S. 395. According to Dunlap, one of the reports, which 

concerned postmiles 35.5 to 45.9, reflected, “ ‘Between October 1, 2010 and September 

30, 2013, 9.1% of accidents reported within the project limits were cross centerline 

collisions.’ ”

D. REPLY

In its reply to the opposition, Caltrans contended that roadway striping is part of 

the design plan and therefore is a design issue—not an operations issue. In regard to the 

alleged loss of design immunity, Caltrans asserted that a physical change in U.S. 395 

miles away from the subject location could not support a loss of design immunity 

because the change is not connected to the subject location. Additionally, Caltrans 

asserted it was improper to rely on Dunlap’s hearsay regarding the reports.

DISCUSSION

A. STANDARD OF REVIEW

The denial of a summary judgment motion is reviewed under the de novo 

standard. (Buss v. Superior Court (1997) 16 Cal.4th 35, 60.) “In considering a request 

for summary judgment by a defendant, the statute instructs that such a party ‘has met his 

or her burden of showing that a cause of action has no merit if that party has shown that 

one or more elements of the cause of action . . . can[not] be established, or that there is a 

complete defense to that cause of action. Once the defendant . . . has met that burden, 

the burden shifts to the plaintiff . . . to show that a triable issue of one or more material 
6

facts exists as to that cause of action or a defense thereto.’ ” (Johnson v. Alameda 

County Medical Center (2012) 205 Cal.App.4th 521, 527.)

B. DESIGN IMMUNITY

Caltrans asserted that design immunity provided it a complete defense. “A 

public entity may be liable for personal injuries caused by the ‘dangerous condition’ of 

its property. (Gov. Code, §§ 830, 835.) An entity may avoid liability, however, through 

the affirmative defense of . . . design immunity. (Gov. Code, § 830.6.) ‘A public entity 

claiming design immunity must establish three elements: (1) a causal relationship 

between the plan or design and the accident; (2) discretionary approval of the plan or 

design prior to construction; and (3) substantial evidence supporting the reasonableness 

of the plan or design.’ ” (Menges v. Department of Transportation (2020) 59 

Cal.App.5th 13, 20 (Menges).) 

The first issue we address is the causal relationship between the design and the 

accident. “A [c]ausal relationship is proved by evidence the injury-producing feature 

was actually a part of the plan approved by the governmental entity . . . .” (Higgins v. 

State of California (1997) 54 Cal.App.4th 177, 185, abrogated on another point in 

Cornette v. Department of Transp. (2001) 26 Cal.4th 63, 73-74 & fn. 3; see also 

Flournoy v. State (1969) 275 Cal.App.2d 806, 811-812.)

The 2010 design for the addition of a centerline rumble strip to the subject 

location includes restriping. The design indicates which sections of the roadway should 

be striped as no passing zones and that the “pavement markers shall be placed . . . in 
7

rumble strip depressions.” The restriping design was approved by Hardimon, a 

registered civil engineer. 

The 2010 design reflects that from postmile 33.58 to postmile 36.71, the 

restriping should indicate that passing is permitted. Caltrans’s expert, Engelmann, 

asserted that the Castillos’ collision occurred “at or near postmile 35.96.” The 

Castillos’ expert, Dunlap, asserted the collision occurred at approximate[ly] Post Mile 

36.13.” If the accident occurred at postmile 35.96 or 36.13, then it falls within the 2010 

restriping design that allowed for passing, i.e., between postmiles 33.58 and 36.71. 

Therefore, the broken yellow striping that allowed for passing at the subject location 

was part of the 2010 restriping design.

The Castillos assert that the collision was caused by the subject location being 

striped for passing when the sight distance was inadequate for passing. Thus, there is an 

alleged causal relationship between the design, i.e., the 2010 design to stripe the subject 

location for passing, and the collision. 

The Castillos asserted that striping was an operations issue, not a design issue. 

To support their assertion, the Castillos cited the deposition testimony of Caltrans’s 

expert, Engelmann. Engelmann was asked, “[W]hat type of stripe is utilized is an 

operations issue; correct?” He responded, “It—it goes hand [in] hand. You can’t really 

separate the two. You—you—they work together.” Engelmann did not indicate that 

striping is purely an operations issue. Rather, he indicated that it is both a design and an 

operations issue. Given the details for restriping that were included in the 2010 design, 

there is not a triable issue of fact regarding the restriping being part of the design.
8

The second element we address is the discretionary approval element, which 

“asks whether a person vested with discretion to approve the plan did approve the plan 

or design that was built.” (Hampton v. County of San Diego (2015) 62 Cal.4th 340, 

356.) Caltrans’s expert, Engelmann, declared that Caltrans engineers exercise 

discretionary authority when deciding whether to approve a project’s design prior to 

construction. Then, after construction is complete, an engineer decides whether to 

approve it “as-built” to indicate that the construction conforms to the plans. 

The restriping portion of the 2010 design is marked as approved on January 14, 

2010, by registered civil engineer Hardimon. The “as-built” approval date is July 28, 

2010, which indicates that the restriping occurred sometime between January 15, 2010 

and July 27, 2010. Thus, Hardimon’s approval of the restriping design occurred prior to 

construction. One can infer from Hardimon’s stamp on the plans that he was a Caltrans 

engineer, which means he had discretion to approve or reject the striping prior to 

construction. Because Hardimon had discretion to approve the restriping plans, and he 

approved them, we conclude the discretionary approval element was met.2 

2

 After receiving the tentative opinion from this court, but prior to oral 

argument, the Castillos submitted a list of additional authorities. The Castillos failed to 

indicate in what way the listed authorities were “not available in time to be included in 

the [return].” (Cal. Rules of Court, rule 8.254(a).) Nevertheless, we will briefly discuss 

two of the cases cited: Johnson v. State (1968) 69 Cal.2d 782 (Johnson) and State v.

I’Anson (1974 Alaska) 529 P.2d 188 (I’Anson). The list lacked pinpoint citations, so we 

have done our best to infer which sections of the opinions the Castillos deem relevant. 

Government Code section 820.2 provides, “[A] public employee is not liable for 

an injury resulting from his act or omission where the act or omission was the result of 

the exercise of the discretion vested in him . . . .” In Johnson, our Supreme Court 

discussed the type of acts that are discretionary and thus deserving of immunity under 

[footnote continued on next page]
9

The third issue is the reasonableness of the plan or design. “The court’s role in 

evaluating the third element of . . . design immunity is not to provide a de novo 

interpretation of the design, but instead to decide whether there is ‘any substantial 

evidence’ supporting its reasonableness. [Citation.] ‘Any substantial evidence’ to 

establish this third element of the immunity may consist of the following: Discretionary 

approval of the design plans themselves [citation]; the expert opinion of a civil engineer 

as to the reasonableness of the design [citation]; or evidence the design or plan complies 

with prevailing professional standards [citation]. ‘A mere conflict in the testimony of 

expert witnesses provides no justification for the matter to go to a lay jury who will then 

second-guess the judgment of skilled public officials.’ ” (Menges, supra, 59 

Government Code section 820.2. The high court explained, “ ‘[I]t would be difficult to 

conceive of any official act, no matter how directly ministerial, that did not admit of 

some discretion in the manner of its performance, even if it involved only the driving of 

a nail.’ ” (Johnson, supra, 69 Cal.2d at p. 788.) The court then set forth various factors 

for determining “whether the agency in a particular case should have immunity.” (Id. at 

p. 789.) In other words, not every discretionary decision deserves governmental 

immunity.

The Alaska Supreme Court cited to Johnson when determining that roadway 

striping was not the type of “broad . . . policy decision” by a separate branch of 

government that deserved immunity. (I’Anson, supra, 529 P.2d at pp. 193-194.) The 

Alaska court concluded, “[R]esolution of questions such as whether or not the state 

properly striped or marked a portion of highway as it relates to the state’s duty of care to 

users of the highway presents facts that courts are equipped to evaluate within 

traditional judicial fact-finding.” (I’Anson, at p. 194.) 

The problem with relying on Johnson, in the instant case, is that Johnson does 

not discuss design immunity (Gov. Code, § 830.6), rather, it discusses immunity for

discretionary acts (Gov. Code, § 820.2). (Johnson, supra, 69 Cal.2d at pp. 787-790.) 

Because “Johnson interpreted a different statute employing different language from that 

found in [Government Code] section 830.6,” we do not find it to be persuasive authority 

in this case. (Hampton v. County of San Diego, supra, 62 Cal.4th at p. 354.) In turn, we 

do not find I’Anson to be persuasive authority in this case.
10

Cal.App.5th at p. 21.) “ ‘ “[A]s long as reasonable minds can differ concerning whether 

a design should have been approved, then the governmental entity must be granted 

immunity.” ’ ” (Id. at p. 20.) “ ‘We are not concerned with whether the evidence of 

reasonableness is undisputed; the statute provides immunity when there is substantial 

evidence of reasonableness, even if contradicted.’ ” (Id. at p. 19.)

The restriping portion of the 2010 design is marked as approved on January 14, 

2010, by registered civil engineer Hardimon. Hardimon’s discretionary approval of the 

plans is evidence of the design’s reasonableness. (Menges, supra, 59 Cal.App.5th at p. 

21.) Engelmann, who is also a registered civil engineer, opined that the design was 

reasonable. Engelmann went to the subject location and examined it. Engelmann’s 

expert opinion is further evidence of the design’s reasonableness. (Menges, at p. 21.) 

Therefore, there is substantial evidence of the design’s reasonableness.

The Castillos assert that Engelmann’s opinion is not reliable because 

Engelmann’s opinion is based on an area 1,000 feet south of the crash site. Assuming 

the Castillos are correct that Engelmann’s opinion of the crash site cannot be credited, 

there is still substantial evidence that the design is reasonable because “[d]iscretionary 

approval of the design plans themselves” can demonstrate reasonableness. (Menges, 

supra, 59 Cal.App.5th at p. 21.) Engelmann explained that Caltrans engineers exercise 

discretionary authority when deciding whether to approve project plans prior to 

construction. Therefore, Hardimon’s approval, by itself, is substantial evidence of the 

reasonableness of the design.
11

The Castillos assert there is not substantial evidence of the design being 

reasonable because the design fails to comply with prevailing professional standards in 

that the minimum sight distance standards for passing were not met. The Castillos 

assert the HDM provides the applicable standard, which is a minimum sight distance of 

2,300 feet in a 65-mile-an-hour zone. The Castillos assert the sight distance at the 

subject location fell to 1,599 feet. Caltrans asserts the relevant minimum sight distance

for passing is provided by the California Manual on Uniform Traffic Control Devices 

(MUTCD), which requires a sight distance of 1,100 feet.

The Castillos’ expert, Dunlap, asserted the HDM applies to the subject location 

because the HDM’s longer sight distance guidelines concern passing in an oncoming 

traffic lane where two vehicles are traveling toward each other at 65 miles per hour. By 

contrast, the MUTCD’s shorter sight distance requirement applies to situations 

involving passing “stationary vehicles or other stationary objects.” When illustrating 

the concept of stationary objects in the roadway, Dunlap gave the examples of “a 

vehicle waiting at [an] intersection or along the side of the road preparing to enter the 

stream of traffic.” Dunlap’s explanation fails to indicate in what scenario Caltrans 

would place a passing lane in an intersection or in an area where vehicles stop on the 

side of a road. Besides, the proper standard to apply is part of the experts’ opinions on 

reasonableness. As noted, that experts do not agree is irrelevant so long as there is 

substantial evidence that the design was reasonable. 

Further, Dunlap failed to cite to sections of the HDM to support his conclusions 

concerning when the HDM applies versus the MUTCD. Thus, Dunlap has failed to 
12

adequately clarify why the HDM, rather than the MUTCD, applies to the subject 

location. As a result, Hardimon’s approval of the restriping plan remains substantial 

evidence of the reasonableness of the design. 

In sum, the broken line striping allowing for passing was part of the 2010 

restriping plans; the broken line striping allowing for passing was alleged to have been a 

substantial factor in causing the crash; and Hardimon’s approval of the 2010 restriping 

plan constitutes substantial evidence of the reasonableness of the restriping plan. 

Therefore, Caltrans established that it had design immunity.

C. LOSS OF DESIGN IMMUNITY

In opposing the motion for summary judgment, the Castillos asserted Caltrans 

had lost its design immunity. “To demonstrate loss of design immunity a plaintiff must 

establish three elements: (1) the plan or design has become dangerous because of a 

change in physical conditions; (2) the public entity had actual or constructive notice of 

the dangerous condition thus created; and (3) the public entity had a reasonable time to 

obtain the funds and carry out the necessary remedial work to bring the property back 

into conformity with a reasonable design or plan, or the public entity, unable to remedy 

the condition due to practical impossibility or lack of funds, had not reasonably 

attempted to provide adequate warnings.” (Cornette v. Department of Transp., supra, 

26 Cal.4th at p. 72.)

In regard to the first element, the Castillos had to establish that “the plan or 

design, under changed physical conditions, has produced a dangerous condition of 

public property.” (Baldwin v. State of California (1972) 6 Cal.3d 424, 434.) 
13

“ ‘Dangerous condition’ means a condition of property that creates a substantial (as 

distinguished from a minor, trivial or insignificant) risk of injury when such property or 

adjacent property is used with due care in a manner in which it is reasonably foreseeable 

that it will be used.” (Gov. Code, § 830, subd. (a).)

In the Castillos’ opposition to the motion, the Castillos asserted a physical 

condition of U.S. 395, north of the subject location, physically changed when a passing 

lane was removed in 2014. The Castillos asserted that the subject location was rendered 

dangerous by the change because “it failed to meet the sight-distance requirements for a 

passing zone.” We understand the Castillos’ argument as follows: The removal of the 

passing lane north of the subject location meant that, if southbound drivers wanted to 

pass slower moving vehicles without waiting, then they would do so in the subject 

location but the subject location was dangerous due to inadequate sight distance for 

passing. 

In attempting to establish that the 2014 removal of the passing lane created a 

dangerous condition, the Castillos relied upon Dunlap’s description of a report entitled 

“Project Report (Safety Improvement) EA 0N9720,” which, according to Dunlap, 

reflected, “ ‘Between October 1, 2010 and September 30, 2013, 9.1% of accidents 

reported within the project limits were cross centerline collisions.” Further, the 

Castillos relied upon Dunlap’s description of another report entitled “The 2005 Two and 

Three-Lane Monitoring Report.” According to Dunlap, the 2005 report reflected the 

subject location needed improvements, such as a centerline rumble strip, to reduce

cross-centerline crashes.
14

The Castillos contend the passing lane was removed in 2014, but their evidence 

of dangerousness predates 2014. If the removal of the passing lane allegedly created the 

dangerous condition, then the Castillos need evidence of the road being dangerous after 

the passing lane was removed. (Baldwin v. State of California, supra, 6 Cal.3d at p. 438 

[“changed physical conditions produce[] a dangerous condition of public property”].) 

To the extent the Castillos are asserting the subject location was dangerous prior to 

2014, and the removal of the passing lane exacerbated the dangerousness, there is no 

evidence of the dangerousness being exacerbated because the Castillos do not provide 

post-2014 evidence of elevated dangerousness following removal of the passing lane. 

A further problem with the Castillos’ evidence is that they rely upon Dunlap’s 

description of the two reports rather than including the reports as exhibits. In the trial 

court, Caltrans objected to Dunlap’s descriptions of the reports because the reports were 

not attached as exhibits. “[A] witness’s on-the-record recitation of sources relied on for 

an expert opinion does not transform inadmissible matter into ‘independent proof’ of 

any fact.” (People v. Gardeley (1996) 14 Cal.4th 605, 619, disapproved on other 

grounds in People v. Sanchez (2016) 63 Cal.4th 665, 686, fn. 13.) Dunlap’s 

descriptions of the two reports cannot be relied upon to prove dangerousness because 

the reports were not produced in court. In sum, the Castillos failed to demonstrate the 

subject location became dangerous following to the 2014 removal of the passing lane. 

As a result, the Castillos failed to establish that Caltrans lost its design immunity.
15

DISPOSITION

The petition is granted. Let a writ of mandate issue directing the trial court to 

vacate its order denying Caltrans’s motion for summary judgment and to enter an order 

granting the motion for summary judgment. Caltrans is awarded its costs in this writ 

proceeding. (Cal. Rules of Court, rule 8.493(a)(1)(A).)
