        While a public entity may be liable for injuries caused by dangerous conditions of
public property (Gov. Code, §§ 830, 835),1 the entity may avoid liability through the
affirmative defense of design immunity (§ 830.6). (Hampton v. County of San Diego

        1   Statutory references are to the Government Code unless otherwise indicated.
(2015) 62 Cal. 4th 340, 342.) For design immunity to apply, the public entity “ ‘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.’ ” (Ibid.)
       The present case involves the second element – discretionary approval. Plaintiff
Erik Rodriguez contends that a public official’s approval of a design does not constitute
an exercise of discretionary authority under section 830.6 if the official admits that he or
she never actually considered whether to utilize the safety feature the plaintiff asserts
would have prevented his or her injuries. We reject Rodriguez’s contention and affirm
the judgment.
                  FACTUAL AND PROCEDURAL BACKGROUND
       On the morning of April 29, 2013, Rodriguez was a passenger in a pickup truck
that was traveling westbound on State Route 152 (SR 152) toward Los Banos when the
truck ran off the road. At the accident location, SR 152 is a four-lane divided expressway
with the westbound direction consisting of two 12-foot wide lanes, an eight-foot wide
paved right shoulder, and a metal beam guardrail to the right of the outside shoulder.
After the truck passed Box Car Road, it veered from the number one (fast) lane, across
the number two (slow) lane and paved shoulder, and off the road to the right. The truck
struck the end of the guardrail, went over an irrigation canal, and eventually came to rest,
catching fire with the occupants still inside. Rodriguez and the driver were injured, and
another passenger was killed.
       Rodriguez sued the Department of Transportation (Caltrans) for, among other
things, maintaining an allegedly dangerous condition of public property. (§ 835.)2
Rodriguez alleged the guardrail was inadequate for its intended purpose, and the northern

       2
       Rodriguez also alleged a cause of action for premises liability against Caltrans,
and named San Luis Canal Company as an additional defendant.

                                              2.
edge of the roadway and shoulder did not contain warning features, such as a “rumble
strip,” that would alert a driver who inadvertently veered onto the shoulder.
       Caltrans moved for summary judgment or summary adjudication of issues on the
grounds of, inter alia, design immunity under section 830.6 and the absence of evidence
of a dangerous condition of public property.3 In support of the design immunity defense,
Caltrans proferred design plans for SR 152 from 1992, 2002, and 2011 construction
projects at the accident site; declarations of state engineers who explained their
discretionary authority to approve those design plans and their actual approval of the
plans; and declarations of other state engineers who confirmed the construction of
SR 152 conformed to the approved plans.
       The 1992 plans at the accident site involved installing a metal beam guardrail,
widening the roadside to include an 8-foot paved shoulder and three feet of compacted
shoulder backing that extended to the north end of the adjacent culvert, and flattening the
existing roadside slope. Licensed civil engineer Shira Rajendra, the Caltrans project
engineer who drafted the 1992 plans, declared that he had discretionary authority to
approve the plans, which he exercised by signing them, and he would not have approved
the plans had they not met appropriate engineering standards. With respect to the use of
rumble strips, Rajendra declared: "I did not consider using rumble strips on the shoulders
because at the time I approved the [1992] plans . . . , the use of rumble strips was not a
common practice. In 1992, there were no standards or policies which addressed or called
for the design of shoulder rumble strips. In 1992, the absence of shoulder rumble strips at
the subject location met the then existing standards for roadways.”

       3   In his opposition to the summary judgment motion, Rodriguez abandoned the
other two grounds on which Caltrans brought the motion – that he could not prove that
Caltrans failed to maintain the guardrail and that Caltrans could not be sued for premises
liability.

                                             3.
       The resident engineer responsible for the construction of the 1992 plans, Michael
Honma, declared the project was completed in accordance with the plans Rajendra
approved, as evidenced by the “AS BUILT” stamp shown on the applicable plan sheets.
Honma explained that rumble strips were not installed because they were not included in
the 1992 plans.
       The 2002 plans consisted of a pavement maintenance project and placement of a
seal coat at the accident location, while the 2011 plans involved placing an overlay of the
existing asphalt at several specified locations on SR 152, including the accident location.
The project engineers for both projects, John Fukano and Jose Alicea II, declared that
they exercised their discretionary authority in approving the plans, and that each plan did
not include rumble strips because neither engineer received a directive from “District 10
Traffic Safety” to install the strips. The resident engineers on each plan project, Nomer
Gutierrez and Sukhminder Deol, declared the projects were completed in according with
the plans, as evidenced by the “AS BUILT” stamp shown on the applicable plan sheets,
and the plans did not include the addition of rumble strips.
        Caltrans’s expert, consulting civil engineer Kim Nystrom, opined the absence of
rumble strips in all of the plans was reasonable because there was no identified need for
them. Caltrans did not widely use shoulder rumble strips in 1992, and they would not
have been included in design plans unless there was a documented need for them, such as
a history of vehicles running off the road. As for the later plans, the fact rumble strips
were not included indicated the district’s traffic safety branch did not recommend their
use. According to Nystrom, the reasonableness of the plans was further supported by the
fact there had not been any collisions at the accident site that involved vehicles departing
the roadway to the right and striking either the guardrail or irrigation ditch.
       Rodriguez opposed the motion, stating that he had elected to proceed only on the
“ ‘absence of rumble strips’ theory of ‘dangerous condition’ liability[,]” and he was not
contesting the first or third elements of design immunity, namely the existence of a causal

                                              4.
relationship and reasonableness of the design. On that basis, he asserted only two issues
remained: (1) whether there had been discretionary approval of a design plan within the
meaning of the statute; and (2) whether the failure to install rumble strips was a
dangerous condition.
       As to discretionary approval, Rodriguez did not dispute that any of the project
engineers had discretionary authority to approve the 1992, 2002, or 2011 plans or that
construction conformed to the approved designs. Instead, he argued Caltrans could not
establish the discretionary approval element because Rajendra, who approved the 1992
plans, stated in his declaration that he did not consider placing rumble strips on the
shoulders. Rodriguez also argued there was a triable issue of fact as to whether the
failure to install rumble strips was a dangerous condition. In support, he proferred the
declaration of retained expert Edward Ruzak, a civil and traffic engineer, who opined the
absence of rumble strips constituted a dangerous condition, as well as evidence of other
vehicle collisions. In reply, Caltrans lodged numerous objections to the evidence of other
collisions and Ruzak’s declaration.
       The trial court granted summary judgment in Caltrans’s favor on Rodriguez’s
dangerous condition of public property claim based on design immunity. The trial court
noted that Rodriguez had conceded the first and third elements of design immunity,
causation and reasonableness. As for the second element, the trial court found the
undisputed material facts and supporting declarations of Caltrans engineers Rajendra,
Fukano, and Alicea, established discretionary approval of the design plans at the accident
location prior to construction, and the design plans approved in 1992, 2002, and 2011,
included a paved shoulder and the absence of rumble strips. In addition, Nystrom’s
declaration provided substantial evidence supporting the reasonableness of the design
plans. This shifted the burden to Rodriguez to show the existence of a triable issue of
material fact, which Rodriguez failed to do, as he did not offer any admissible evidence
demonstrating a triable issue of fact on the discretionary approval element. In light of its

                                             5.
ruling, the trial court declined to rule on whether the absence of rumble strips constituted
a dangerous condition. The trial court also declined to rule on Caltrans’s objections
because Rodriguez’s evidence was not material to the trial court’s disposition of the
motion, citing Code of Civil Procedure section 437c, subdivision (q). Judgment
subsequently was entered in Caltrans’s favor.
                                      DISCUSSION
   I.       General Principles Governing Design Immunity
        “Under the Government Claims Act, ‘[a] public entity is not liable for an injury,’
‘[e]xcept as otherwise provided by statute.’ ” (Hampton, supra, 62 Cal.4th at p. 347.)
“The Government Claims Act (Act) provides for direct liability on the part of public
entities for injuries caused by maintaining dangerous conditions on their property when
the condition ‘created a reasonably foreseeable risk of the kind of injury which was
incurred’ and either an employer’s negligence or wrongful act or omission caused the
dangerous condition or the entity was on ‘actual or constructive notice’ of the condition
in time to have taken preventive measures.” (Id. at pp. 347-348.)
        “Even if a dangerous condition is demonstrated, a public entity may still prevail
through a variety of statutory immunities, which the public entity may assert as an
affirmative defense.” (Gonzales v. City of Atwater (2016) 6 Cal.App.5th 929, 945
(Gonzales).) Here, we are concerned with the affirmative defense of design immunity
under section 830.6.4 As we stated above, the design immunity defense consists of three

        4Section 830.6 provides, in relevant part: “Neither a public entity nor a public
employee is liable under this chapter for an injury caused by the plan or design of a
construction of, or an improvement to, public property where such plan or design has
been approved in advance of the construction or improvement by the legislative body of
the public entity or by some other body or employee exercising discretionary authority to
give such approval or where such plan or design is prepared in conformity with standards
previously so approved, if the trial or appellate court determines that there is any
substantial evidence upon the basis of which (a) a reasonable public employee could have
adopted the plan or design or the standards therefor or (b) a reasonable legislative body or

                                             6.
elements the public entity must prove. We are concerned here with the second element –
“discretionary approval of the plan or design prior to construction.” (Cornette v.
Department of Transportation (2001) 26 Cal. 4th 63, 66 (Cornette).) “The rationale for
design immunity is to prevent a jury from second-guessing the decision of a public entity
by reviewing the identical questions of risk that had previously been considered by the
government officers who adopted or approved the plan or design.” (Id. at p. 69.)
       “Design immunity is often raised on a motion for summary judgment or nonsuit,
thereby enabling the trial court to find the defense established as a matter of law.
[Citation.] ‘The first two elements, causation and discretionary approval, may only be
resolved as issues of law if the facts are undisputed.” (Gonzales, supra, 6 Cal.App.5th at
p. 946.)
       “The third element, whether there is any substantial evidence of the
reasonableness of the public entity’s approval of the plan or design, is a question
statutorily reserved for the court, not a jury.” (Gonzalez, supra, 6 Cal.App.5th at p. 946.)
The “trial or appellate court” is required to determine whether “there is any substantial
evidence upon the basis of which (a) a reasonable public employee could have adopted
the plan or design or the standards therefor or (b) a reasonable legislative body or other
body or employee could have approved the plan or design or the standards therefor.”
(§ 830.6; Cornette, supra, 26 Cal.4th at p. 72.) The evidence of reasonableness need not
be undisputed, as the statute provides immunity when there is substantial evidence of
reasonableness, even if contradicted. (Grenier v. City of Irwindale (1997)
57 Cal. App. 4th 931, 940 (Grenier).) Immunity must be granted as long as reasonable
minds can differ concerning whether a design should have been approved; “ ‘[t]he statute

other body or employee could have approved the plan or design or the standards
therefor.”

                                             7.
does not require that property be perfectly designed, only that it be given a design which
is reasonable under the circumstances.’ ” (Id. at p. 941.)
         Rodriguez appealed from the judgment entered after the trial court granted
Caltrans’s summary judgment motion. “A trial court properly grants a motion for
summary judgment where ‘all the papers submitted show that there is no triable issue as
to any material fact and that the moving party is entitled to a judgment as a matter of
law.’ (Code Civ. Proc. § 437c, subd. (c).) ‘Because this case comes before us after the
trial court granted a motion for summary judgment, we take the facts from the record that
was before the trial court when it ruled on that motion. [Citation.] “ ‘We review the trial
court’s decision de novo, considering all the evidence set forth in the moving and
opposing papers except that to which objections were made and sustained.’ ” [Citation.]
We liberally construe the evidence in support of the party opposing summary judgment
and resolve doubts concerning the evidence in favor of that party.’ ” (Hartford Casualty
Ins. Co. v. Swift Distribution, Inc. (2014) 59 Cal. 4th 277, 286.)
   II.      Discretionary Approval
         The sole element of design immunity at issue here is discretionary approval. This
“ ‘simply means approval in advance of construction by the legislative body or officer
exercising discretionary authority.’ [Citation.] A detailed plan, drawn up by a competent
engineering firm, and approved by a city engineer in the exercise of his or her
discretionary authority, is persuasive evidence of the element of prior approval.”
(Grenier, supra, 57 Cal.App.4th at p. 940.)
         Here, Caltrans presented undisputed evidence that the 1992, 2002, and 2011 plans
were designed and approved by Caltrans civil engineers, who had the discretionary
authority to approve the plans. The plans consist of detailed drawings of the accident
location, including the absence of rumble strips. This evidence demonstrates the
discretionary approval element as a matter of law. (See, e.g., Gonzales, supra,
6 Cal.App.5th at p. 947 [discretionary approval established as a matter of law where

                                              8.
professional engineering firm designed the plans, the city engineer with discretionary
authority reviewed and approved the plans, which were also approved by the city
council]; Laabs v. City of Victorville (2008) 163 Cal. App. 4th 1242, 1263 [evidence that
an engineer employed by the public entity “reviewed and approved” construction plan
established discretionary approval as a matter of law]; Grenier, supra, 57 Cal.App.4th at
p. 941 [city established discretionary approval as a matter of law where the plans were
prepared by a civil engineer and approved by another civil engineer].)
       Rodriguez acknowledges this evidence would have been sufficient to establish
discretionary approval if not for a statement by the Caltrans engineer who approved the
1992 plans, Rajendra, that he “did not consider using rumble strips on the shoulders.”
Citing to a sentence in Grenier that “[d]esign immunity does not immunize decisions
which were not made,” (Grenier, supra, 57 Cal.App.4th at p. 940) and the rationale
behind design immunity, Rodriguez contends Caltrans cannot establish discretionary
approval because the purported decision-maker never considered the particular feature or
design element at issue, namely whether to install rumble strips. He asserts that if there
was never a decision made concerning rumble strips, the quality of the deliberative
process cannot be assessed.
       Our Supreme Court interpreted the discretionary approval element of
section 830.6 in Hampton. There, the plaintiffs contended that “ ‘approv[al]’ by one
‘exercising discretionary authority’ (§ 830.6), requires an exercise of discretion in the
sense of an exercise of judgment or choice, and . . . ‘one cannot truly exercise judgment
or make a choice without an awareness of what is to be judged or chosen.’ ” (Hampton,
supra, 62 Cal.4th at p. 348.) Thus, the plaintiffs argued, “ ‘only an engineer who realizes
a design does not conform to governing standards can truly make a discretionary decision
to approve the design despite its nonconformity. By contrast, an engineer who approves
a nonconforming design on the mistaken belief it conformed to governing standards has
acted through inadvertence, not discretion.’ ” (Id. at pp. 348-349.)

                                             9.
       The Court rejected this contention, as such claims are considered under the
reasonableness element of the statute. (Hampton, supra, 62 Cal.4th at p. 349.) Noting
that the issue called for statutory interpretation, the Court explained that because the
statute permits the discretionary approval element to be established by evidence of either
appropriate discretionary approval or the plan conformed with previously approved
standards,5 evidence of an employee’s awareness of and compliance with standards is not
required to establish discretionary approval by the appropriate employee. (Hampton,
supra, 62 Cal.4th at pp. 349, 350.)
       The Court concluded the structure of the statute as a whole supported this
interpretation. As the Court explained, the statute contains a three-part structure: “Under
the statute, once causation and approval by an authorized employee or compliance with
appropriately adopted standards is established, there is immunity” as long as the trial or
appellate court determines there is substantial evidence that “a reasonable public
employee could have adopted the plan or design or the standards therefor,” or “a
reasonable legislative body or other body or employee could have approved the plan or
design or the standards therefor.” (Hampton, supra, 62 Cal.4th at p. 350, citing § 830.6.)
The three-part structure implies the court evaluates the wisdom of the design under the
reasonableness element, and not under the element asking the jury to decide whether an
employee vested with discretion to approve the plans actually approved them. (Hampton,
supra, 62 Cal.4th at p. 350.)
       The Court concluded that, when considered as a whole, it was “plain that
section 830.6 was intended to avoid second-guessing the initial design decision adopted

       5 “Neither a public entity nor a public employee is liable under this chapter for an
injury caused by the plan or design . . . where such plan or design has been approved . . .
by some . . . employee exercising discretionary authority to give such approval or where
such plan or design is prepared in conformity with standards previously so
approved . . . .” (§ 830.6, italics added).

                                             10.
by an employee vested with authority to approve it, except to the extent the court
determines that the employee’s approval of the design was unreasonable. It is at the
reasonableness stage that the court would consider whether an employee, in either
knowingly or unknowingly approving a design that deviates from applicable standards,
adopted a design that a ‘reasonable legislative body or other body or employee could
have approved.’ (§ 830.6).” (Hampton, supra, 62 Cal.4th at p. 351.)
       In Gonzales, supra, 6 Cal.App.5th 929, we applied the rationale of Hampton to
reject the plaintiffs’ claim that to establish “approv[al]” by one “exercising discretionary
authority” (§ 830.6), the public entity was required to present evidence of a
“ ‘deliberat[ive] process that resulted in the exercise of judgment[.]’ ” (Gonzales, supra,
6 Cal.App.5th at p. 948.) There, the plaintiffs argued that without proof of a decision or
explanation of what the public entity considered regarding the appropriateness of its
plans, there was no evidence an actual discretionary decision was made and therefore no
design immunity. (Ibid.) After a thorough analysis of the Court’s decision in Hampton,
we concluded the plaintiffs’ interpretation of the statute – that proof of how a decision is
made is necessary to establish the exercise of discretionary authority – is not supported
by the statute’s language or intent. (Gonzales, supra, 6 Cal.App.5th at pp. 952-953.)
Specifically, we stated this interpretation conflicted with the statutory language, “as an
exercise of ‘discretionary authority to give such approval’ does not entail a conscious
weighing of design or plan options, but does require the employee to use discretion in
approving the plan or design.” (Ibid.)
       The rationale of Hampton and Gonzales applies equally here. Both cases establish
that under the language of section 830.6, all that is required to establish the discretionary
approval element is evidence that an employee with discretionary authority approved the
plan or design. Here, Caltrans presented such evidence. That the project engineer also
stated he did not consider the use of rumble strips is irrelevant to the discretionary
approval element. It is relevant, however, to the reasonableness element, as it is at that

                                             11.
stage the court considers whether it is reasonable that an employee, in approving a design
without considering a particular design feature, adopted a design that “a reasonable . . .
employee could have approved.” (§ 830.6; Hampton, supra, 62 Cal.4th at p. 351.) As in
Hampton, Rodriguez’s “contrary interpretation would undermine the function of the
statute’s reasonableness element, a result that would be inconsistent with our duty to read
the elements of the statute together, harmonizing and giving effect to them all.”
(Hampton, supra, 62 Cal.4th at p. 351.)
       Rodriguez asserts Hampton has no application to this case, as it did not address
whether the discretionary approval element “is satisfied by the approval of a plan which
does not include an allegedly, necessary safety feature because the entity ‘did not
consider’ using the feature one way or the other.” While the plaintiffs’ argument in
Hampton was different, namely that the discretionary approval element could not be
satisfied if the official who approved the design did not realize the design deviated from
governing standards, the Court’s statutory interpretation applies with equal force here,
where the plaintiff contends this element cannot be satisfied where the official who
approved the design admits he or she did not consider a particular design feature.
       Rodriguez states that his “ ‘real complaint’ is that the project engineer never made
a decision one way or the other because he ‘did not consider rumble strips’ at all.” He
asserts the discretionary approval element does not “speak to, nor immunize, failures to
decide, only decisions actually made.” In his view, design immunity is vitiated if the
employee with discretionary authority to approve a plan or design admits he or she failed
to consider the particular feature or design, the absence of which a plaintiff later alleges
made the property dangerous.
       Rodriguez’s view of what constitutes a design decision, however, is too narrow.
Here, the design decision made in 1992 was to construct a bare paved shoulder at the
accident location. The wisdom of this decision, and whether the project engineer should
have considered whether to install rumble strips, is reviewed, not at the discretionary

                                             12.
approval stage, but at the reasonableness stage. To conclude otherwise “would implicate
the adequacy of the deliberative process at the discretionary approval stage and would
lead a jury into just the sort of second-guessing concerning the wisdom of the design that
the statute was intended to avoid.” (Hampton, supra, 62 Cal.4th at p. 350.)
       Rodriguez’s reliance on Cameron v. State of California (1972) 7 Cal. 3d 318
(Cameron), is misplaced. There, the plaintiffs alleged their injuries, incurred when they
lost control of their car on a highway, were caused by a dangerous condition, namely
uneven banking or “superelevation,” on a curve in the road. (Id. at pp. 321-323.) Our
Supreme Court reversed a judgment of nonsuit in favor of the State of California on its
design immunity claim. (Id. at pp. 325-326.) The Court noted that while the State had
produced evidence the highway design plans were prepared by appropriate county
employees and approved by the county board of supervisors, the plaintiffs produced
evidence the design plans contained no specification of superelevation; instead, they
merely showed the course of the 60-foot right of way and the elevation of the white
center stripe. (Ibid.) In that situation, design immunity did not attach because there was
no evidence the superelevation was the result of, or conformed to, a design approved by
the public entity vested with discretionary authority. (Id. at p. 326.) In so holding, the
Court explained the policy behind design immunity would not be implicated because
“there would be no reexamination of a discretionary decision . . . because there has been
no such decision proved.” (Ibid.)
       Unlike the plan in Cameron, which did not include the alleged dangerous feature –
uneven banking on a curve in the road – the plans here did include the alleged dangerous
feature – a paved roadway shoulder absent rumble strips. Therefore, a decision was
proved – to build the road with a bare shoulder. Caltrans presented evidence that the
engineer with discretionary authority approved the plans and the shoulder was
constructed in conformity with them. Thus, the evidence established the shoulder that
was actually constructed was the result of or conformed to a design approved by the

                                             13.
employee vested with discretionary authority, which provided a basis for concluding any
liability for injuries caused by the absence of rumble strips was immunized by
section 830.6.
       This is consistent with another case Rodriguez relies on, Grenier, supra,
57 Cal. App. 4th 931. While the appellate court in Grenier cited Cameron for the
proposition that “[d]esign immunity does not immunize decisions which were not
made[,]” it went on to state: “Thus, the injury-producing feature must have been a part of
the plan approved by the governmental entity.” (Grenier, supra, 57 Cal.App.4th at
pp. 940-941, fn. omitted.) The appellate court concluded that both causation and
discretionary approval were established by evidence that the plaintiff’s claim of
inadequate drainage relied on features that were part of the written plans prepared by a
civil engineer and approved by the city. (Id. at p. 941.) Similarly here, the injury-
producing feature, the absence of rumble strips, was part of the plans approved by
Caltrans through its project engineer.
       Citing Anderson v. City of Thousand Oaks (1976) 65 Cal. App. 3d 82, Rodriguez
argues that because “section 830.6 is intended to immunize ‘conscious design
choices’[,]” immunity is defeated if it can be shown that a design feature that is absent
from the plans was not considered. As we have already explained, however, Hampton
instructs that “the discretionary approval element of design immunity asks whether a
person vested with discretion to approve the plan did approve the plan or design that was
built, and that the question whether it was wise to approve the plan is judged under the
reasonableness element of the statute.” (Hampton, supra, 62 Cal.4th at p. 357.) In view
of Hampton, whether an omitted design feature is a “conscious design choice” is relevant,
not to whether discretionary approval element is satisfied, but to whether the design was
reasonable.
       Finally, contrary to Rodriguez’s assertion, we do not hold that a public entity is
entitled to design immunity any time an employee with authority signs off on a plan and

                                            14.
another employee or engineer attests the plan is reasonable. Instead, we merely hold
where, as here, an employee with discretionary authority signs off on a plan that includes
the injury-producing feature, and it was reasonable to do so, design immunity applies.
This is not a situation, as in Castro v. City of Thousand Oaks (2015) 239 Cal. App. 4th
1451, where the injury-producing feature was not part of the approved project plans but
was added after plan approval. Instead, the injury-producing feature, the absence of
rumble strips, was part of the plan. Since Rodriguez concedes that Caltrans established
both a causal relationship between the plans and the accident, and the reasonableness of
those plans, we conclude the trial court properly determined Caltrans established, as a
matter of law, the affirmative defense of design immunity.6
                                     DISPOSITION
       The judgment is affirmed. Costs on appeal are awarded to Caltrans.

       6 The parties also address an issue the trial court did not decide, namely whether
SR 152 at the accident location constituted a dangerous condition. We do not reach the
issue, however, because even if there was a dangerous condition, Caltrans is immune
from liability under section 830.6.
