The California Environmental Quality Act (CEQA) (Pub. Resources Code,

§ 21000 et seq.)1 establishes a comprehensive scheme to provide long-term

protection to the environment. It prescribes review procedures a public agency

must follow before approving or carrying out certain projects. For policy reasons,

the Legislature has expressly exempted several categories of projects from review

under CEQA. (See § 21080, subd. (b)(1) – (15).) By statute, the Legislature has

also directed the Secretary of the Natural Resources Agency (Secretary) to

establish ―a list of classes of projects that have been determined not to have a

significant effect on the environment and that shall be exempt from‖ CEQA.

(§ 21084, subd. (a).) ―In response to that mandate,‖ the Secretary ―has found‖ that

certain ―classes of projects . . . do not have a significant effect on the

environment‖ and, in administrative regulations known as guidelines, has listed

those classes and ―declared [them] to be categorically exempt from the

requirement for the preparation of environmental documents.‖ (Cal. Code Regs.,

tit. 14, § 15300; see id., § 15000 et seq., Guidelines for Implementation of CEQA

(Guidelines).) Respondent City of Berkeley (City), in approving a permit

application to build a 6,478-square-foot house with an attached 3,394-square-foot

10-car garage, relied on two of the class exemptions the Secretary has established

pursuant to the Legislature‘s mandate: (1) ―Class 3,‖ which comprises the

construction of ―new, small facilities or structures,‖ including ―[o]ne single-family

residence, or a second dwelling unit in a residential zone‖ (Guidelines, § 15303);

and (2) ―Class 32,‖ which comprises ―in-fill development‖ projects, i.e., projects

that ―occur[] within city limits on a project site of no more than five acres

substantially surrounded by urban uses‖ and that meet other specified conditions

(Guidelines, § 15332).

The Court of Appeal invalidated the permit approval, relying on Guidelines

section 15300.2, subdivision (c), which provides: ―A categorical exemption shall

not be used for an activity where there is a reasonable possibility that the activity

will have a significant effect on the environment due to unusual circumstances.‖

In the Court of Appeal‘s view, that a proposed activity may have a significant

effect on the environment is itself an unusual circumstance that renders the

categorical exemptions inapplicable. Finding substantial evidence of a fair

argument that the proposed project may have a significant environmental impact,

the court held that the exemptions the City invoked do not apply, and it ordered

the trial court to issue a writ of mandate directing the City to set aside the permit

2



approvals and its finding of a categorical exemption, and to order preparation of an

environmental impact report (EIR).

We granted review to consider the proper interpretation and application of

Guidelines section 15300.2, subdivision (c). We reverse the Court of Appeal‘s

decision.

I. FACTUAL BACKGROUND

Real parties in interest and respondents Mitchell Kapor and Freada Kapor-

Klein (applicants) want to build a large house on their lot on Rose Street in

Berkeley. The lot is on a steep slope (approximately 50 percent grade) in a

heavily wooded area. In May 2009, their architect applied to the City for a use

permit to demolish the existing house on the lot and to build a 6,478-square-foot

house with an attached 3,394-square-foot 10-car garage. The residence would be

built on two floors, would include an open-air lower level, and would cover about

16 percent of the lot.

In January 2010, the City‘s zoning adjustments board (Board), after holding

a public hearing and receiving comments about the project, approved the use

permit. It found the project exempt from CEQA review under Guidelines

sections 15303, subdivision (a), and 15332. The former, which the Secretary has

designated Class 3, includes ―construction and location of limited numbers of new,

small facilities or structures,‖ including ―[o]ne single-family residence, or a

second dwelling unit in a residential zone,‖ and ―up to three single-family

residences‖ ―[i]n urbanized areas.‖ (Guidelines, § 15303, subd. (a).) The latter,

which the Secretary has designated Class 32, applies to a project ―characterized as

in-fill development‖ meeting the following conditions: (1) it ―is consistent with

the applicable general plan designation and all applicable general plan policies as

well as with applicable zoning designation and regulations‖; (2) it ―occurs within

city limits on a project site of no more than five acres substantially surrounded by

urban uses‖; (3) its ―site has no value[] as habitat for endangered, rare or

3



threatened species‖ and ―can be adequately served by all required utilities and

public services‖; and (4) its approval ―would not result in any significant effects

relating to traffic, noise, air quality, or water quality.‖ (Guidelines, § 15332.) The

Board also found that Guidelines section 15300.2, subdivision (c), does not

preclude use of these categorical exemptions because the project as proposed and

approved will not have any significant effects on the environment due to unusual

circumstances.

Several residents of the City, including appellant Susan Nunes Fadley, filed

an appeal with the city council, arguing in part that CEQA‘s categorical

exemptions do not apply because the proposed project‘s ―unusual size, location,

nature and scope will have significant environmental impact on its surroundings.‖

They asserted that the proposed residence would be ―one of the largest houses in

Berkeley, four times the average house size in its vicinity, and situated in a canyon

where the existing houses are of a much smaller scale.‖ They submitted evidence

that, of Berkeley‘s over 17,000 single-family residences, only 17 exceed 6,000

square feet, only 10 exceed 6,400 square feet, and only one exceeds 9,000 square

feet. They also asserted that the proposed residence would exceed the maximum

allowable height under Berkeley‘s municipal code and would be inconsistent with

the policies of the City‘s general plan, and that an EIR is appropriate to evaluate

the proposed construction‘s potential impact on noise, air quality, historic

resources, and neighborhood safety. In response, the City‘s director of planning

and development stated that 16 residences within 300 feet of the project have a

greater floor-area-to-lot-area ratio and that 68 Berkeley ―dwellings‖ exceed 6,000

square feet, nine exceed 9,000 square feet, and five exceed 10,000 square feet.

The city council received numerous letters and e-mails regarding the

appeal, some in support and some in opposition. Among the appeal‘s supporters

was Lawrence Karp, an architect and geotechnical engineer. In a letter dated

April 16, 2010, Karp stated: (1) he had reviewed the architectural plans and

topographical survey filed with the Board, and had visited the proposed

4



construction site; (2) ―[p]ortions of the major fill for the project are shown to be

placed on an existing slope inclined at about 42º (~1.1h:1v) to create a new slope

more than 50º (~0.8h:1v)‖; (3) ―[t]hese slopes cannot be constructed by earthwork

and all fill must be benched and keyed into the slope which is not shown in the

sections or accounted for in the earthwork quantities. To accomplish elevations

shown on the architectural plans, shoring and major retaining walls not shown will

have to be constructed resulting in much larger earthwork quantities than now

expected‖; (4) the ―massive grading‖ necessary would involve ―extensive trucking

operations‖; (5) the work that would be necessary ―has never before been

accomplished in the greater area of the project outside of reservoirs or construction

on the University of California campus and Tilden Park‖; (6) the project site is

―located alongside the major trace of the Hayward fault and it is mapped within a

state designated earthquake-induced landslide hazard zone‖; and (7) ―the project

as proposed is likely to have very significant environmental impacts not only

during construction but in service due to the probability of seismic lurching of the

oversteepened side-hill fills.‖

In a second letter addressing the investigation of geotechnical engineer

Alan Kropp, Karp stated: (1) no ―fill slopes‖ were shown in Kropp‘s plan and

―the recommendations for retaining walls do not include lateral earth pressures for

slopes with inclinations of more than 2h:1v (~27º) or for wall heights more than

12 feet‖; (2) the project‘s architectural plans ―include cross-sections and elevations

that are inconsistent with the Site Plan and limitations in‖ Kropp‘s report; (3) ―all

vegetation will have to be removed for grading, and retaining walls totaling 27 feet

in height will be necessary to achieve grades. Vertical cuts for grading and

retaining walls will total about 43 feet (17 feet for bench cutting and 26 feet for

wall cutting). [¶] A drawing in the [Kropp] report depicts site drainage to be

collected and discharged into an energy dissipater dug into the slope, which is

inconsistent with the intended very steep fill slopes‖; and (4) ―the project as

proposed is likely to have very significant environmental impacts not only during

5



construction, but in service due to the probability of seismic lurching of the

oversteepened side-hill fills.‖

In response, Kropp stated that the project site is in an area where an

investigation is required to evaluate the potential for landslides, and that he had

conducted the necessary investigation and found there is, in fact, no landslide

hazard. Kropp also stated that, in raising concerns about ―side-hill fill,‖ Karp had

―misread[]‖ the project plans. According to Kropp, ―the only fill placed by the

downhill portion of the home will be backfill for backyard retaining walls and

there will be no side-hill fill placed for the project. The current ground surface,

along with the vegetation, will be maintained on the downhill portion of the lot.‖

Because there will not, as Karp claimed, be any ―steep, side-hill fill constructed,‖

Karp‘s concerns do not apply to the proposed construction. A civil engineer, Jim

Toby, also submitted a letter stating that he saw ―no evidence‖ in the project plans

that fill will be placed ― ‗directly on steep slopes‘ ‖ and that Karp‘s contrary

assertion is based on a ―misreading‖ of the plans.

In support of the permit approval, the City‘s director of planning and

development submitted a supplemental report stating: ―A geotechnical report was

prepared and signed by a licensed Geotechnical Engineer and a Certified

Engineering Geologist. This report concluded that the site was suitable for the

proposed dwelling from a geotechnical standpoint and that no landslide risk was

present at the site. Should this project proceed, the design of the dwelling will

require site-specific engineering to obtain a building permit.‖

The city council addressed the appeal at a meeting on April 27, 2010. Karp

was one of the speakers at the meeting. He began by stating his credentials,

explaining that he (1) is ―a geotechnical engineer specializing in foundation

engineering and construction‖; (2) has ―an earned doctorate degree in civil

engineering and other degrees from U.C. Berkeley including two masters and a

post-doctoral certificate in earthquake engineering‖; (3) is ―fully licensed‖ and had

―taught foundational engineering at Berkeley for 14 years and at Stanford for

6



three‖; (4) has ―experience‖ that ―includes over 50 years of design and

construction in Berkeley‖; and (5) ―prepare[s] feasibility studies before, and

engineering during, construction of unusual projects.‖ After affirming the opinion

he had earlier stated in his letters, he offered this response to the assertion that he

had misread the project plans: ―The recent report from [applicants] say I don‘t

know how to read architectural drawings, but I have been a licensed architect for

many years and I do know how. [¶] Their reports have not changed my opinion.‖

After hearing from Karp, Kropp, and others, the city council adopted the Board‘s

findings, affirmed the permit approval, and dismissed the appeal. The city

planning department later filed a notice of exemption, stating that the project is

categorically exempt from CEQA under Guidelines sections 15303, subdivision

(a), and 15332, and that Guidelines section 15300.2 did not apply.

Fadley then filed a petition for writ of mandate in the trial court, joined by

appellant Berkeley Hillside Preservation, which is a self-described unincorporated

association of ―City residents and concerned citizens who enjoy and appreciate the

Berkeley hills and their environs and desire to protect the City‘s historic, cultural,

architectural, and natural resources.‖ Following a hearing, the trial court denied

the petition. It first concluded that the administrative record contains substantial

evidence to support the City‘s application of the Class 32 in-fill and Class 3 small

structures categorical exemptions. It next found that Guidelines section 15300.2,

subdivision (c), did not preclude application of these categorical exemptions

because, notwithstanding evidence of potentially significant environmental effects,

the proposed project does not present any unusual circumstances.

The Court of Appeal reversed. After noting appellants‘ concession, for

purposes of appeal, that the project satisfies the requirements of the Class 3 and

Class 32 exemptions, the Court of Appeal agreed with appellants that the unusual

circumstances exception precludes the City from relying on those exemptions.2 In


2

The concurring opinion prefers to call section 15300.2, subdivision (c), ―the

significant effect exception,‖ based on its title. (Conc. opn. of Liu, J., post, at p.

7



the court‘s view, ―the fact that proposed activity may have an effect on the

environment is itself an unusual circumstance‖ that triggers the exception,

―because such action would not fall ‗within a class of activities that does not

normally threaten the environment,‘ and thus should be subject to further

environmental review.‖ The court next reasoned that the standard of judicial

review for an agency‘s determination that the exception does not apply is whether

the record contains evidence of a fair argument of a significant effect on the

environment, not whether substantial evidence supports the agency‘s

determination. Finally, finding substantial evidence of a fair argument that the

proposed project may have a significant environmental impact, the court held that

the unusual circumstances exception renders the categorical exemptions

inapplicable. It ordered the trial court ―to issue a writ of mandate directing the

City to set aside the approval of use permits and its finding of a categorical

exemption, and to order the preparation of an EIR.‖

We then granted respondents‘ petition for review.

II. DISCUSSION

As they did in the Court of Appeal, appellants concede for purposes of this

appeal that the proposed project comes within the terms of the Class 3 (small

structures) and Class 32 (in-fill development) exemptions under the Guidelines.

What they do not concede is that the City may rely on those exemptions. In their

view, as the Court of Appeal held, the unusual circumstances exception precludes

such reliance. Respondents, in challenging the Court of Appeal‘s decision, raise


6.) Our use of the term ―unusual circumstances exception‖ is consistent with the
Court of Appeal‘s decision in this case and the vast majority of published case
law. Of course, a provision‘s title ―is never allowed to enlarge or control the
language in the body of the [provision].‖ (Hagar v. Sup. of Yolo Co. (1874) 47
Cal. 222, 232; see DaFonte v. Up-Right, Inc. (1992) 2 Cal.4th 593, 602 [―Title or
chapter headings are unofficial and do not alter the explicit scope, meaning, or
intent of a statute.‖].)

8



two primary arguments: (1) a proposed project‘s potential significant effect on the

environment is not, as the Court of Appeal held, itself an unusual circumstance

that triggers the exception, and an unusual circumstance apart from the project‘s

potential environmental effect is a prerequisite to the exception‘s application; and

(2) in reviewing the City‘s conclusion that the exception is inapplicable, the Court

of Appeal should have determined whether there was substantial evidence in the

record to support that conclusion, not whether the record contains evidence of a

fair argument of a significant effect on the environment. To these arguments, we

now turn.

A. A Potentially Significant Environmental Effect Is Not Alone

Sufficient to Trigger the Unusual Circumstances Exception.

Generally, the rules that govern interpretation of statutes also govern

interpretation of administrative regulations. (Guzman v. County of Monterey

(2009) 46 Cal.4th 887, 898; Cal. Drive-in Restaurant Assn. v. Clark (1943) 22

Cal.2d 287, 292.) Thus, we begin here with the language of the unusual

circumstances exception, giving effect to its usual meaning and avoiding

interpretations that render any language surplusage. (Brewer v. Patel (1993) 20

Cal.App.4th 1017, 1021.) As noted earlier, Guidelines section 15300.2,

subdivision (c), provides: ―A categorical exemption shall not be used for an

activity where there is a reasonable possibility that the activity will have a

significant effect on the environment due to unusual circumstances.‖ The plain

language of this provision supports the view that, for the exception to apply, it is

not alone enough that there is a reasonable possibility the project will have a

significant environmental effect; instead, in the words of the Guideline, there must

be ―a reasonable possibility that the activity will have a significant effect on the

environment due to unusual circumstances.‖ (Guidelines, § 15300.2, subd. (c),

italics added.)

Contrary to our rules for interpreting regulations, appellants‘ proposed

construction, which mirrors that of the Court of Appeal and which the concurring

opinion would adopt, would give no meaning to the phrase ―due to unusual

circumstances.‖ According to appellants, this phrase is merely ―descriptive‖ in

that ―[u]nusual circumstances‖ are simply ―self-evident underpinnings‖ when a

project that otherwise satisfies the requirements of a categorical exemption

nevertheless ―has potentially significant impacts.‖ Likewise, the concurring

opinion asserts that ―the phrase ‗unusual circumstances‘ . . . simply describes the

nature of a project that, while belonging to a class of projects that typically have

no significant environmental effects, nonetheless will have such effects.‖ (Conc.

opn, post, at p. 2.) In other words, in the view of appellants and the concurring

opinion, the phrase ―due to unusual circumstances‖ adds nothing to the meaning of

the regulation, and the exception applies if there is a fair argument that a project

―may‖ (according to appellants) or ―will‖ (according to the concurring opinion

(ibid.)) have a significant environmental effect. However, had that been the

Secretary‘s intent, the phrase ―due to unusual circumstances‖ would, no doubt,

have been omitted from the regulation; rather than confuse the issue with

meaningless language, the regulation would clearly and simply provide that the

exception applies ―if there is a reasonable possibility that the activity will have a

significant effect on the environment.‖ Reading the phrase ―due to unusual

circumstances‖ out of the regulation, as appellants and the concurring opinion

propose, would be contrary to the principle of construction that directs us ―to

accord meaning to every word and phrase in a regulation.‖ (Price v. Starbucks

Corp. (2011) 192 Cal.App.4th 1136, 1145.)

In addition, we agree with respondents that, under the construction of

appellants and the concurring opinion, the categorical exemptions the Legislature,

through the Secretary, has established would have little, if any, effect. CEQA

10



specifies that environmental review through preparation of an EIR is required only

―[i]f there is substantial evidence . . . that the project may have a significant effect

on the environment.‖ (§ 21080, subd. (d).) As a corollary to this principle, CEQA

also specifies that, if ―[t]here is no substantial evidence, in light of the whole

record before the lead agency, that the project may have a significant effect on the

environment,‖ then the proposed project is not subject to further CEQA review.

(§ 21080, subd. (c)(1).) Guidelines section 15061, subdivision (b)(3), captures

these principles by specifying: ―Where it can be seen with certainty that there is

no possibility that the activity in question may have a significant effect on the

environment, the activity is not subject to CEQA.‖

Under these provisions, where there is no substantial evidence a proposed

project may have a significant environmental effect, further CEQA review is

unnecessary; no categorical exemption is necessary to establish that proposition.

According to appellants, under the unusual circumstances exception, the

categorical exemptions are inapplicable unless an agency ―check[s] its files‖ and

finds no ―evidence of potentially significant impacts.‖ But this is precisely the

inquiry an agency makes under Guidelines section 15061, subdivision (b)(3), to

determine whether the proposed project is subject to CEQA review in the first

instance. (Muzzy Ranch Co. v. Solano County Airport Land Use Com. (2007) 41

Cal.4th 372, 387 (Muzzy Ranch) [under Guidelines, § 15061, subd. (b)(3), agency

must determine whether the evidence in the administrative record shows no

possibility the proposed activity may have a significant effect on the

environment].) And appellants‘ test for determining whether the unusual

circumstances exception applies —whether there is a ―reasonable possibility‖ the

proposed project ―will have a significant effect on the environment‖ (Guidelines, §

15300.2, subd. (c)) — is precisely the test used to determine whether Guidelines

section 15061, subdivision (b)(3), applies. (California Farm Bureau Federation v.

11



California Wildlife Conservation Bd. (2006) 143 Cal.App.4th 173, 194

[Guidelines, § 15061, subd. (b)(3), inapplicable if ―there is a reasonable possibility

that a proposed project will have a significant effect upon the environment‖].)

Thus, under appellants‘ view, the categorical exemptions would serve no purpose;

they would apply only when the proposed project is, by statute and Guidelines

section 15061, subdivision (b)(3), already outside of CEQA review.

Appellants assert that applying a categorical exemption despite a proposed

project‘s potential significant environmental effect would contravene CEQA

statutes and the Legislature‘s intent in passing CEQA. They rely on three CEQA

provisions: (1) section 21100, subdivision (a), which directs preparation of an EIR

―on any project . . . that may have a significant effect on the environment‖; (2)

section 21151, which similarly directs preparation of an EIR ―on any project . . .

which may have a significant effect on the environment‖; and (3) section 21082.2,

subdivision (d), which states that an EIR ―shall‖ be prepared ―[i]f there is

substantial evidence, in light of the whole record before the lead agency, that a

project may have a significant effect on the environment.‖ This statutory

authority, appellants assert, ―does not allow categorical exemptions for any project

that may have a significant effect on the environment.‖ In other words, ―the

documented presence of a potential environmental effect . . . always defeat[s] a

categorical exemption.‖ ―[T]he statutory authority [the Legislature] has given to

the Secretary only allows categorical exemption for projects that have no

significant environmental effect, and ‗no statutory policy exists in favor of

applying categorical exemptions where a fair argument can be made that a project

will create a significant effect on the environment.‘ ‖ Thus, appellants assert,

requiring more than a showing that a proposed project may have a significant

effect in the environment ―would be inconsistent with‖ CEQA‘s statutory

―mandates.‖

12



Appellants‘ argument ignores a basic principle of statutory interpretation:

courts ―do not construe statutes in isolation, but rather read every statute ‗with

reference to the entire scheme of law of which it is part so that the whole may be

harmonized and retain effectiveness.‘ ‖ (People v. Pieters (1991) 52 Cal.3d 894,

899.) Thus, we must consider the three sections appellants cite, not in isolation,

but ― ‗in the context of the statutory framework as a whole‘ ‖ in order to

harmonize CEQA‘s ― ‗various parts.‘ ‖ (Palos Verdes Faculty Assn. v. Palos

Verdes Peninsula Unified Sch. Dist. (1978) 21 Cal.3d 650, 659 [construing the Ed.

Code].)

Here, several CEQA provisions, as well as their evolution, are relevant to

the issue. When the Legislature enacted CEQA in 1970, it directed the Governor‘s

Office of Planning and Research (OPR), ―in conjunction with appropriate state,

regional, and local agencies,‖ to ―coordinate the development of objectives,

criteria, and procedures to assure the orderly preparation and evaluation of‖ EIRs.

(Former § 21103, added by Stats. 1970, ch. 1433, § 1, pp. 2780, 2782.) Two years

later, in Friends of Mammoth v. Board of Supervisors (1972) 8 Cal.3d 247, 259

(Mammoth), we held that CEQA applies, not just to public projects, but also to

private activities requiring a government permit or similar entitlement. Before

Mammoth, it had been ―generally believed‖ that CEQA ―appl[ied] only to projects

undertaken or funded by public agencies.‖ (Friends of Lake Arrowhead v. Board

of Supervisors (1974) 38 Cal.App.3d 497, 513.) Cognizant of our decision‘s

potential ramifications, after recognizing that ―the reach of the statutory phrase,

‗significant effect on the environment,‘ is not immediately clear,‖ we noted: ―To

some extent this is inevitable in a statute which deals, as the [CEQA] must, with

questions of degree. Further legislative or administrative guidance may be

forthcoming on this point among others.‖ (Mammoth, supra, at p. 271, italics

added.) We then added: ―[C]ommon sense tells us that the majority of private

13



projects for which a government permit or similar entitlement is necessary are

minor in scope — e.g., relating only to the construction, improvement, or

operation of an individual dwelling or small business — and hence, in the absence

of unusual circumstances, have little or no effect on the public environment. Such

projects, accordingly, may be approved exactly as before the enactment of the

[CEQA].‖ (Id. at p. 272.)

The Legislature immediately responded to Mammoth by amending CEQA

through urgency legislation. (See County of Inyo v. Yorty (1973) 32 Cal.App.3d

795, 803.) As relevant here, it added section 21083, which generally directed the

OPR, ―as soon as possible,‖ to ―prepare and develop proposed guidelines for the

implementation of [CEQA],‖ and directed the Secretary to ―certify and adopt the

[OPR‘s proposed] guidelines pursuant to‖ the Administrative Procedure Act.

(Stats. 1972, ch. 1154, § 1, pp. 2271, 2272-2273.) These directives exist today as

subdivisions (a) and (e) of section 21083. More specifically, in several provisions,

the Legislature provided for categorical exemptions to CEQA. In section 21084, it

provided: ―The guidelines prepared and adopted pursuant to Section 21083 shall

include a list of classes of projects which have been determined not to have a

significant effect on the environment and which shall be exempt from the

provisions of [CEQA]. In adopting the guidelines, the Secretary . . . shall make a

finding that the list or classification of projects referred to in this section do not

have a significant effect on the environment.‖ (§ 21084, as added by Stats. 1972,

ch. 1154, § 1, pp. 2271, 2273.) This provision remains substantively the same

today. In former section 21085, the Legislature provided that ―[a]ll classes of

projects designated pursuant to Section 21084 . . . shall be exempt from the

provisions of [CEQA].‖ (Stats. 1972, ch. 1154, § 1, pp. 2271, 2273.) The

substance of this section appears today in section 21080, subdivision (b)(9), which

provides that CEQA ―does not apply‖ to ―[a]ll classes of projects designated

14



pursuant to Section 21084.‖ Finally, the Legislature enacted section 21086 to

establish a mechanism for challenging the Secretary‘s categorical exemptions.

(Stats. 1972, ch. 1154, § 1, pp. 2271, 2273-2274.) Subdivision (a) of that section

provides: ―A public agency may, at any time, request the addition or deletion of a

class of projects, to the list designated pursuant to Section 21084. That request

shall be made in writing to the [OPR] and shall include information supporting the

public agency‘s position that the class of projects does, or does not, have a

significant effect on the environment.‖ Subdivision (b) of section 21086 requires

the OPR to ―review each request‖ and ―submit‖ a recommendation to the

Secretary, and authorizes the Secretary, ―[f]ollowing the receipt of [the OPR‘s]

recommendation,‖ to ―add or delete the class of projects to the list of classes of

projects designated pursuant to Section 21084 that are exempt from the

requirements of [CEQA].‖ Subdivision (c) of section 21086 then provides: ―The

addition or deletion of a class of projects, as provided in this section, to the list

specified in Section 21084 shall constitute an amendment to the guidelines

adopted pursuant to Section 21083 and shall be adopted in the manner prescribed

in Sections 21083 and 21084.‖

Collectively, these provisions indicate that the Legislature intended to

establish by statute ―classes of projects‖ that ―have been determined not to have a

significant effect on the environment,‖ to require the OPR and the Secretary to

apply their expertise and identify those ―classes‖ by ―mak[ing] a finding‖ that the

projects they comprise ―do not have a significant effect on the environment,‖ and

to ―exempt‖ from CEQA proposed projects within the classes the OPR and the

Secretary have identified. (§ 21084, subd. (a).) This conclusion comports with

the impetus for the Legislature‘s enactment of these provisions: our decision in

Mammoth, which (1) observed that CEQA‘s applicability turns on ―questions of

degree,‖ (2) stated that ―the majority‖ of private projects ―may be approved

15



exactly as before‖ CEQA‘s enactment because they ―are minor in scope . . . and

hence, in the absence of unusual circumstances, have little or no effect on the

public environment,‖ and (3) called for ―[f]urther legislative or administrative

guidance‖ on these issues. (Mammoth, supra, 8 Cal.3d at pp. 271-272.) To

address these considerations, the Legislature, through the Guidelines, intended to

enumerate classes of projects that are exempt from CEQA because,

notwithstanding their potential effect on the environment, they already ―have been

determined not to have a significant effect on the environment.‖ (§ 21084.) The

Guidelines implement this intent, by setting forth the ―classes of projects‖ that the

Secretary, acting ―[i]n response to [the Legislature‘s] mandate,‖ ―has found . . . do

not have a significant effect on the environment.‖ (Guidelines, § 15300.) Thus,

construing the unusual circumstances exception as requiring more than a showing

of a fair argument that the proposed activity may have a significant environmental

effect is fully consistent with the Legislature‘s intent.

By contrast, as earlier explained, appellants‘ construction of the unusual

circumstances exception would render useless and unnecessary the statutes the

Legislature passed to identify and make exempt classes of projects that have no

significant environmental effect. Try as they might, appellants can identify no

purpose or effect of the categorical exemption statutes if, as they assert, a showing

of a fair argument of a potential environmental effect precludes application of all

categorical exemptions. Construing the unusual circumstances exception to apply

any time there is a reasonable possibility of a significant environmental effect

would, therefore, contravene our duty to adopt a construction that gives effect to

all parts of the statutory and regulatory framework, rather than one that renders

part of the framework ―wholly useless and unnecessary.‖ (French Bank Case

(1879) 53 Cal. 495, 530.)

16



The concurring opinion‘s attempt to succeed where appellants have

failed — i.e., to show that the categorical exemptions still have some ―value‖

under their construction (conc. opn, post, at p. 9) — is also unpersuasive. The

concurring opinion first asserts that proposed projects enjoy ―a considerable

procedural advantage‖ when an agency finds that they fall within the terms of an

exempt category. (Conc. opn., post, at p. 10.) As to such projects, the concurring

opinion notes, an agency need not follow any particular procedure, include any

written determination, undertake an initial study, or adopt a negative declaration.

(Ibid.) However, the same is true of proposed projects that fall within the terms of

Guidelines section 15061, subdivision (b)(3), i.e., projects that are ―not subject to

CEQA‖ because ―it can be seen with certainty that there is no possibility that

[they] may have a significant effect on the environment.‖ (See Muzzy Ranch,

supra, 41 Cal.4th at p. 380 [initial study not required where Guidelines, § 15061,

subd. (b)(3) applies].) As already explained, the concurring opinion‘s

interpretation renders the categorical exemptions duplicative of this guideline, and

the concurring opinion does not persuasively demonstrate otherwise. Thus, its

discussion of these so-called procedural advantages fails to show that, under its

interpretation, the categorical exemptions have independent value.

The concurring opinion also notes that, when an agency finds that a project

meets the terms of a categorical exemption, it ―impliedly finds that it has no

significant impact,‖ and ―the burden shifts to‖ project opponents ―to produce

evidence‖ that the unusual circumstances exception applies. (Conc. opn, post, at

pp. 9-10.) This is significant, the concurring opinion maintains, because ―[i]n

many cases, categorical exemptions are not litigated, and the applicability of the

exemption is evident.‖ (Id. at p. 10.)

However, even if a proposed project faces no opposition, an agency

invoking a categorical exemption may not simply ignore the unusual

17



circumstances exception; it must ―consider the issue of significant effects . . . in

determining whether the project is exempt from CEQA where there is some

information or evidence in the record that the project might have a significant

environmental effect.‖ (Association for Protection etc. Values v. City of Ukiah

(1991) 2 Cal.App.4th 720, 732 (Ukiah).) This follows from Guidelines section

15061, subdivisions (a) and (b)(2), which, respectively, (1) direct a lead agency to

determine whether a proposed project is ―exempt from CEQA,‖ and (2) specify

that a project is exempt if a categorical exemption applies ―and the application of

that categorical exemption is not barred by one of the exceptions set forth in

Section 15300.2.‖ Thus, an agency may not apply a categorical exemption

without considering evidence in its files of potentially significant effects,

regardless of whether that evidence comes from its own investigation, the

proponent‘s submissions, a project opponent, or some other source. Moreover,

under the concurring opinion‘s interpretation, if those files contain ―substantial

evidence‖ of a mere ―fair argument‖ that the project will have significant

environmental effects, the agency may not apply a categorical exemption. (Conc.

opn, post, at p. 14.) Thus, under the concurring opinion‘s interpretation of the

unusual circumstances exception, the ―considerable procedural advantage‖ the

concurring opinion posits is largely illusory. (Id. at p. 10.)

Also illusory is the ―second advantage‖ that, in the view of the concurring

opinion, gives some value to categorical exemptions under its interpretation: the

comparative arguments‖ available to project proponents when an opponent

invokes the unusual circumstances exception. (Conc. opn, post, at p. 11.)

According to the concurring opinion, proponents may ―argue,‖ if ―supported by

evidence,‖ that (1) the project‘s effects are ―typical‖ of those generated by projects

in the exempt category, ―such that few or no projects in the category would be

exempt if the effects were deemed significant,‖ and (2) ―the project‘s dimensions

18



or features are not unusual compared to typical projects in the exempt category,

thereby suggesting that the project is similar to those that the Secretary has

determined not to have a significant environmental effect.‖ (Id. at pp. 11-12.)

However, under the fair argument test the concurring opinion would apply here,

―an agency is merely supposed to look to see if the record shows substantial

evidence of a fair argument that there may be a significant effect. [Citations.] In

other words, the agency is not to weigh the evidence to come to its own conclusion

about whether there will be a significant effect. It is merely supposed to inquire,

as a matter of law, whether the record reveals a fair argument. . . . ‗ ―[I]t does not

resolve conflicts in the evidence but determines only whether substantial evidence

exists in the record to support the prescribed fair argument.‖ ‘ [Citation.] ‖

(Banker’s Hill, Hillcrest, Park West Community Preservation Group v. City of San

Diego (2006) 139 Cal.App.4th 249, 263 (Banker’s Hill); see Guidelines, § 15064,

subd. (f)(1) [a lead agency ―presented with a fair argument that a project may have

a significant effect on the environment . . . shall prepare an EIR even though it

may also be presented with other substantial evidence that the project will not

have a significant effect‖].) Thus, under the concurring opinion‘s interpretation,

evidence a project proponent offers to show that the project will only have typical

effects, dimensions, and features is irrelevant if a project opponent can make a

mere fair argument that those effects, dimensions, or features are not typical, or

that the project will have a significant environmental effect. For these reasons, the

concurring opinion fails to demonstrate that the categorical exemptions would

retain any significant ―value‖ under its interpretation. (Conc. opn, post, at p. 9.)

Moreover, contrary to the assertion of the concurring opinion, even were

the categorical exemptions to retain some limited value under its construction,

there would still be ―reason[s]‖ (conc. opn, post, at p. 14) to reject that

construction. First, as earlier explained (ante, p. 10), because that construction

19



would transform the phrase ―due to unusual circumstances‖ into meaningless

surplusage, it is one we ―should avoid.‖ (Metcalf v. County of San Joaquin (2008)

42 Cal.4th 1121, 1135.) Second, nothing suggests that either the Legislature or the

Secretary intended the categorical exemptions to have such minuscule value. Had

that been their intent, surely they would have expressed it in a more clear, concise,

direct, and obvious way.

Accordingly, the Court of Appeal erred by holding that a potentially

significant environmental effect itself constitutes an unusual circumstance. In

listing a class of projects as exempt, the Secretary has determined that the

environmental changes typically associated with projects in that class are not

significant effects within the meaning of CEQA, even though an argument might

be made that they are potentially significant. The plain language of Guidelines

section 15300.2, subdivision (c), requires that a potentially significant effect must

be ―due to unusual circumstances‖ for the exception to apply. The requirement of

unusual circumstances recognizes and gives effect to the Secretary‘s general

finding that projects in the exempt class typically do not have significant impacts.

As to projects that meet the requirements of a categorical exemption, a

party challenging the exemption has the burden of producing evidence supporting

an exception. (Davidon Homes v. City of San Jose (1997) 54 Cal.App.4th 106,

115; see 1 Kostka & Zischke, Practice under the Cal. Environmental Quality Act

(2d ed. 2008) § 5.71 (citing cases).) As explained above, to establish the unusual

circumstances exception, it is not enough for a challenger merely to provide

substantial evidence that the project may have a significant effect on the

environment, because that is the inquiry CEQA requires absent an exemption.

(§ 21151.) Such a showing is inadequate to overcome the Secretary‘s

determination that the typical effects of a project within an exempt class are not

significant for CEQA purposes. On the other hand, evidence that the project will

20



have a significant effect does tend to prove that some circumstance of the project

is unusual. An agency presented with such evidence must determine, based on the

entire record before it — including contrary evidence regarding significant

environmental effects — whether there is an unusual circumstance that justifies

removing the project from the exempt class.

This reading of the guideline is not inconsistent with the phrase ―reasonable

possibility that the activity will have a significant effect on the environment.‖

(Guidelines, § 15300.2, subd. (c).) A party invoking the exception may establish

an unusual circumstance without evidence of an environmental effect, by showing

that the project has some feature that distinguishes it from others in the exempt

class, such as its size or location. In such a case, to render the exception

applicable, the party need only show a reasonable possibility of a significant effect

due to that unusual circumstance. Alternatively, under our reading of the

guideline, a party may establish an unusual circumstance with evidence that the

project will have a significant environmental effect. That evidence, if convincing,

necessarily also establishes ―a reasonable possibility that the activity will have a

significant effect on the environment due to unusual circumstances.‖ (Guidelines,

§ 15300.2, subd. (c).)

As this discussion demonstrates, our approach is consistent with the

concurring opinion‘s statement of its central proposition: ―When it is shown that a

project otherwise covered by a categorical exemption will have a significant

environmental effect, it necessarily follows that the project presents unusual

circumstances.‖ (Conc. opn, post, at p. 2, italics added.) However, for reasons

already set forth, we part company with the concurring opinion when it moves

from this central proposition to the conclusion that a reviewing court must find the

exception applicable, and overturn an agency‘s application of an exemption, if

there is ―substantial evidence‖ of ―a fair argument that the project will have

21



significant environmental effects.‖ (Ibid.) The Secretary, in complying with the

Legislature‘s command to determine the ―classes of projects‖ that ―do not have a

significant effect on the environment‖ (§ 21084, subd. (a)), necessarily resolved

any number of ―fair arguments‖ as to the possible environmental effects of

projects in those classes. Allowing project opponents to negate those

determinations based on nothing more than ―a fair argument that the project will

have significant environmental effects‖ (conc. opn., post, at p. 12) would be

fundamentally inconsistent with the Legislature‘s intent in establishing the

categorical exemptions.

Appellants assert that Wildlife Alive v. Chickering (1976) 18 Cal.3d 190

(Chickering) precludes us from construing the unusual circumstances exception to

require a showing of something more than a potentially significant environmental

effect. There, we held in relevant part that the setting of hunting and fishing

seasons by the Fish and Game Commission (Commission) was not exempt from

CEQA under Guidelines former section 15107. (Chickering, supra, at p. 205.)

That former guideline established a categorical exemption for ― ‗actions taken by

regulatory agencies . . . to assure the maintenance, restoration, or enhancement of

a natural resource where the regulatory process involves procedures for protection

of the environment‘ ‖ (id. at p. 204), and it described as an example ― ‗the wildlife

preservation activities of the State Department of Fish and Game.‘ ‖ (Id. at p.

205.) We gave two reasons for finding this exemption inapplicable on its terms.

First, the Commission ―is not‖ the Department of Fish and Game. (Ibid.) Second,

and ―[m]ore significantly,‖ several of the statutes that granted powers and duties to

the Department of Fish and Game ―contemplate projects specifically designed for

the preservation of wildlife.‖ (Ibid.) These are the ―departmental functions‖ to

which the former guideline referred in mentioning ―[t]he ‗wildlife preservation

activities of the State Department of Fish and Game.‘ ‖ (Ibid.) ―The

22



[Commission‘s] fixing of hunting seasons, while doubtless having an indirect

beneficial effect on the continuing survival of certain species, cannot fairly or

readily be characterized as a preservation activity in a strict sense.‖ (Ibid.)

After concluding in Chickering that the Commission‘s activity did not fall

within the language of the former guideline, we discussed why it would have been

problematic to ―expand[]‖ that ―language to imply‖ an exemption for that activity.

(Chickering, supra, 18 Cal.3d at p. 206.) Doing so, we stated, would contravene

the ―principle‖ that ―CEQA must be interpreted so as to afford the ‗fullest possible

protection‘ to the environment.‖ (Ibid.) Moreover, we explained in a passage

appellants quote, ―if‖ we ―expand[ed]‖ (id. at p. 206) the former guideline‘s

language ―to cover the commission‘s hunting program, it is doubtful that such a

categorical exemption [would be] authorized under the statute. . . . [N]o regulation

is valid if its issuance exceeds the scope of the enabling statute. [Citations.] The

secretary is empowered to exempt only those activities which do not have a

significant effect on the environment. (Pub. Resources Code, § 21084.) It follows

that where there is any reasonable possibility that a project or activity may have a

significant effect on the environment, an exemption would be improper,‖ and ―the

setting of hunting and fishing seasons has the potential for a significant

environmental impact . . . .‖ (Id. at pp. 205-206.)

For several reasons, appellants‘ reliance on Chickering is unavailing. First,

Chickering predated the Secretary‘s adoption of the unusual circumstances

exception and, thus, addressed neither the meaning nor the validity of that

exception. Second, as here relevant, the only issue in Chickering was whether the

Commission‘s activity fell within the scope of Guidelines former section 15107l.

After concluding it did not, we added the discussion appellants cite, which, to

buttress our conclusion, explored the validity of a hypothetical exemption that

would include the Commission‘s activity. (Chickering, supra, 18 Cal.3d at pp.

23



205-206.) Third, because that added discussion was tangential to the issue before

us and unnecessary to resolve the case, it was, understandably, summary. For

example, it did not consider the broader statutory framework, the evolution of the

CEQA statutes, or the implications of its statement for the effectiveness of various

other CEQA statutes. Finally, in 1993, after we decided Chickering, the

Legislature enacted section 21083.1, which directs courts ―not [to] interpret [the

CEQA statutes] or the state guidelines adopted pursuant to Section 21083 in a

manner which imposes procedural or substantive requirements beyond those

explicitly stated in [CEQA] or in the state guidelines.‖ (§ 21083.1, italics added.)

According to the legislative history, the purpose of this statute was to ―limit

judicial expansion of CEQA requirements‖ and to ― ‗reduce the uncertainty and

litigation risks facing local governments and project applicants by providing a

―safe harbor‖ to local entities and developers who comply with the explicit

requirements of the law.‘ ‖ (Assem. Com. on Natural Resources, Analysis of Sen.

Bill No. 722 (1993-1994 Reg. Sess.) for hearing on July 12, 1993, p. 2.) Given

appellants‘ concession for purposes of appeal that the proposed project here falls

within two of the categorical exemptions, under Guidelines section 15300.2,

subdivision (c), environmental review is necessary only if ―there is a reasonable

possibility [the project] will have a significant effect on the environment due to

unusual circumstances.‖ Given that the listing of a class of projects as exempt

constitutes the Secretary‘s finding, pursuant to the Legislature‘s command, that the

typical effects of projects within that class are not significant within the meaning

of CEQA, interpreting the unusual circumstances exception to require

environmental review absent unusual circumstances would violate the

Legislature‘s express directive in section 21083.1 ―not [to] interpret‖ the CEQA

statutes and the Guidelines ―in a manner which imposes procedural or substantive

requirements beyond those‖ the statutes and the Guidelines ―explicitly state[].‖

24



As we have explained, ―in the . . . years since CEQA was enacted the

Legislature has, for reasons of policy, expressly exempted several categories of

projects from environmental review. (See § 21080, subd. (b)(1)-[(15)].) This

court does not sit in review of the Legislature‘s wisdom in balancing these policies

against the goal of environmental protection because, no matter how important its

original purpose, CEQA remains a legislative act, subject to legislative limitation

and legislative amendment.‖ (Napa Valley Wine Train, Inc. v. Public Utilities

Com. (1990) 50 Cal.3d 370, 376.) Consistent with section 21083.1‘s directive, we

have held that ―rules regulating the protection of the environment must not be

subverted into an instrument for the oppression and delay of social, economic, or

recreational development and advancement.‖ (Citizens of Goleta Valley v. Board

of Supervisors (1990) 52 Cal.3d 553, 576.) Adopting appellants‘ interpretation

would do precisely that, by requiring environmental review of projects that one

could argue may have a significant environmental effect, but that the OPR and the

Secretary, exercising the authority the Legislature has by statute delegated to them

and required them to exercise, have already determined do not, in fact, ―have a

significant effect on the environment.‖ (§ 21084, subd. (a).)

Appellants also substantially rely on this court‘s decision in Mountain Lion

Foundation v. Fish and Game Commission (1997) 16 Cal.4th 105 (Mountain

Lion). There, the majority held in relevant part that the same categorical

exemption previously at issue in Wildlife Alive — which had been renumbered as

Guidelines section 15307 — did not apply to the Commission‘s decision to

remove the Mojave ground squirrel from the threatened species list. (Mountain

Lion, supra, at pp. 124-127.) As noted earlier, that guideline establishes an

exemption for ―actions taken by regulatory agencies as authorized by state law or

local ordinance to assure the maintenance, restoration, or enhancement of a natural

resource where the regulatory process involves procedures for protection of the

25



environment.‖ (Guidelines, § 15307.) The majority found that ―a delisting action

cannot be fairly included within this class‖ because it ―removes rather than secures

[the] protections‖ that an endangered or threatened species enjoys under the

California Endangered Species Act. (Mountain Lion, supra, at p. 125.) Moreover,

the majority added, in light of other Guidelines, a delisting could not come within

a categorical exemption. ―[A] categorical exemption represents a determination

by the Secretary that a particular project does not have a significant effect on the

environment. (§ 21084.)‖ (Mountain Lion, supra, at 124.) ―It follows,‖ the

majority stated in the passage on which appellants rely, ―that an activity that may

have a significant effect on the environment cannot be categorically exempt.‖

(Ibid.) Under Guidelines section 15065, subdivision (a), an agency ―must find‖

that a proposed project may have that effect if it has ― ‗the potential to . . . reduce

the . . . number or restrict the range of an endangered, rare or threatened species.‘ ‖

(Mountain Lion, supra, at p. 124.) Because a delisting, by ―withdraw[ing] existing

levels of protection,‖ ―creates at least the potential for population reduction or

habitat restriction,‖ this guideline ―obligate[s]‖ the Commission ―to find a

delisting may have a significant environmental effect. Such a finding precludes

invocation of a categorical exemption.‖ (Ibid.)

For reasons similar to those earlier discussed in connection with

Chickering, supra, 18 Cal.3d 190, appellants‘ reliance on Mountain Lion is

unavailing. Like Chickering, Mountain Lion addressed neither the meaning nor

the validity of the unusual circumstances exception. Also like Chickering, as here

relevant, Mountain Lion presented only the issue of whether the Commission‘s

activity fell within the express terms of a categorical exemption. Because the

court found it did not, the hypothetical discussion of whether the Secretary could

have established a categorical exemption was tangential, unnecessary, and

summary. In any event, properly understood, the discussion in Mountain Lion

26



stands only for the proposition that the Secretary, having established in one

guideline that a delisting may have a significant effect on the environment, may

not in another guideline ―make a finding‖ that delistings, as a class, ―do not have a

significant effect on the environment‖ and are therefore exempt from CEQA.

(§ 21084.) It does not, as appellants assert, establish that where the Secretary,

exercising statutorily delegated authority, has found that projects of a certain kind

―do not have a significant effect on the environment‖ and are exempt from CEQA,

a proposed project that falls within that class and does not involve any unusual

circumstances is, nonetheless, subject to environmental review if an argument can

be made that it may have a significant effect on the environment. That question

simply was not before us in Mountain Lion, supra, 16 Cal.4th 105.3

B. Standards of Review.

Several CEQA statutes expressly address judicial review of agency action.

Section 21168 provides the standard of review for decisions ―made as a result of a

proceeding in which by law a hearing is required to be given, evidence is required

to be taken and discretion in the determination of facts is vested in a public

agency.‖ Section 21168.5 provides the standard of review in all other actions ―to

attack, review, set aside, void or annul a determination, finding, or decision of a

public agency on the grounds of noncompliance with [CEQA].‖ Because nothing

required the City to hold an evidentiary hearing in this case, the latter section

governs. Under it, a court‘s inquiry is ―whether there was a prejudicial abuse of

discretion. Abuse of discretion is established if the agency has not proceeded in a

manner required by law or if the determination or decision is not supported by


3

Consistent with the preceding analysis, we disapprove Communities for a

Better Environment v. California Resources Agency (2002) 103 Cal.App.4th 98,
129, insofar as it suggests that a proposed project‘s potential environmental effects
alone render the unusual circumstances exception applicable.

27



substantial evidence.‖ (Ibid.) Thus, reversal of the City‘s action here is

appropriate only if (a) the City, in finding the proposed project categorically

exempt, did not proceed in the manner required by law, or (b) substantial evidence

fails to support that finding.4

The parties disagree about how these standards apply to an agency‘s

determination that the unusual circumstances exception is inapplicable.

Respondents, invoking the traditional substantial evidence standard, argue that a

reviewing court must uphold such a determination if substantial evidence supports

it, even if substantial evidence in the record also shows that a contrary conclusion

would be equally, or even more, reasonable. Appellants, on the other hand,

contend that, even if substantial evidence supports the agency‘s determination, a

reviewing court must overturn the determination if there is a fair argument based

on substantial evidence that the proposed project may have a significant effect on

the environment due to unusual circumstances. A fair argument exists, appellants

assert, ―if any facts, fact-based assumptions, or expert opinion in the

administrative record support . . . arguments that [the] exception may apply,

regardless of contrary evidence.‖

The fair argument approach derives from our application of section 21168.5

in No Oil, Inc. v. City of Los Angeles (1974) 13 Cal.3d 68 (No Oil). There, we


4

We have previously observed that ―the standard of review is essentially the

same‖ under sections 21168 and 21168.5. (Laurel Heights Improvement Assn. v.
Regents of University of California
(1993) 6 Cal.4th 1112, 1133, fn. 17 (Laurel
Heights II
).) Section 21168 requires review ―in accordance with the provisions of
Section 1094.5 of the Code of Civil Procedure,‖ and declares that ―the court shall
not exercise its independent judgment on the evidence but shall only determine
whether the act or decision is supported by substantial evidence in the light of the
whole record.‖ Code of Civil Procedure section 1094.5, subdivision (b), provides,
similarly to section 21168.5, that ―[a]buse of discretion is established if the
respondent has not proceeded in the manner required by law, the order or decision
is not supported by the findings, or the findings are not supported by the
evidence.‖

28



reviewed the City of Los Angeles‘s application of section 21151, which requires

preparation of an EIR for a nonexempt project that ―may have a significant effect

on the environment.‖ Although the proposed project in No Oil did not qualify for

an exemption under the CEQA statutes or the Guidelines, Los Angeles had found,

after conducting an initial threshold environmental study, that no EIR was

necessary because the project would not have a significant effect on the

environment. We reversed, concluding that the finding constituted a prejudicial

abuse of discretion under section 21168.5 because, in making it, Los Angeles had

failed to proceed as required by law in two ways: (1) it had not made its

determination in writing; and (2) it had used the wrong standard to determine

whether the proposed project might have a significant effect on the environment.

Regarding the latter, we construed section 21151 to require preparation of an EIR

for a nonexempt project ―whenever it can be fairly argued on the basis of

substantial evidence that the project may have a significant environmental

impact.‖ (No Oil, supra, at p. 75.) At the trial court‘s direction, Los Angeles had

applied ―a far more restrictive test that limited use of an EIR to projects which

may have an ‗important‘ or ‗momentous‘ effect of semi-permanent duration.‖

(Ibid.) In reaching our conclusion, we cited the following factors: (1) ―the

preparation of an EIR is the key to environmental protection under CEQA‖ (ibid.);

(2) the statute speaks, not of projects that will have a significant effect on the

environment, but of projects that ―may‖ have such effect (id. at p. 83, fn. 16); (3)

the Legislature intended that CEQA be interpreted to afford the fullest protection

to the environment within the reasonable scope of the statutory language, but the

test Los Angeles had applied afforded the least possible protection within the

statutory language (id. at p. 85); and (4) by ―bar[ring] preparation of an EIR‖ in

―close and doubtful cases,‖ the test Los Angeles applied would ―defeat the

Legislature‘s objective of ensuring that environmental protection serve as the

29



guiding criterion in agency decisions‖ (id. at p. 84). Because we concluded that

Los Angeles had failed to proceed as required by law, in part by applying the

wrong standard, we expressly declined to decide whether its decision was

―supported by substantial evidence.‖ (Id. at p. 75.)

The Natural Resources Agency has since expressly incorporated No Oil‘s

fair argument approach into the Guidelines. Guidelines section 15064, subdivision

(f)(1), now states: ―If the lead agency determines there is substantial evidence in

the record that the project may have a significant effect on the environment, the

lead agency shall prepare an EIR (Friends of B Street v. City of Hayward (1980)

106 Cal. App. 3d 988). Said another way, if a lead agency is presented with a fair

argument that a project may have a significant effect on the environment, the lead

agency shall prepare an EIR even though it may also be presented with other

substantial evidence that the project will not have a significant effect (No Oil, Inc.

v. City of Los Angeles (1974) 13 Cal. 3d 68).‖5 If, however, an agency‘s ―initial

study‖ for a nonexempt project ―shows that there is no substantial evidence that

the project may have a significant effect‖ on the environment, the agency

―prepares a negative declaration‖ (Guidelines, § 15002, subd. (k)(2)) describing

―the reasons‖ why no EIR is required (§ 21064).

The fair argument standard Guidelines section 15064, subdivision (f)(1),

sets forth applies by its terms to determinations of a lead agency, not of a court.

Under sections 21168 and 21168.5, judicial review of agency decisions is for

abuse of discretion. (Laurel Heights II, supra, 6 Cal.4th at p. 1135.) The scope of

review of an agency‘s application of the fair argument standard is described in

Friends of “B” Street v. City of Hayward (1980) 106 Cal.App.3d 988, 1002


5

This guideline first appeared in 1983 as Guidelines section 15064,

subdivision (g)(1). (See Guidelines, § 15064, Register 83, No. 29 (July 16, 1983)
p. 308.)

(Friends of “B” Street), a decision that section 15064, subdivision (f)(1), cites.

Friends of “B” Street explained that a reviewing court may not uphold an

agency‘s decision ―merely because substantial evidence was presented that the

project would not have [a significant environmental] impact. The [reviewing]

court‘s function is to determine whether substantial evidence support[s] the

agency‘s conclusion as to whether the prescribed ‗fair argument‘ could be made.

If there [is] substantial evidence that the proposed project might have a significant

environmental impact, evidence to the contrary is not sufficient to support a

decision to dispense with preparation of an EIR and adopt a negative declaration,

because it [can] be ‗fairly argued‘ that the project might have a significant

environmental impact. Stated another way, if the [reviewing] court perceives

substantial evidence that the project might have such an impact, but the agency

failed to secure preparation of the required EIR, the agency‘s action is to be set

aside because the agency abused its discretion by failing to proceed ‗in a manner

required by law.‘ ‖ (Friends of “B” Street, supra, at p. 1002.)

There have been several attempts to extend the fair argument standard to

CEQA determinations other than the one at issue in No Oil, supra, 13 Cal.3d 68,

i.e., whether to prepare an EIR for a nonexempt project. We considered, and

rejected, one such attempt in Laurel Heights II, which involved an agency‘s

decision not to recirculate an EIR for public comment. Section 21092.1 requires

recirculation if ―significant new information is added to‖ an EIR after initial

circulation and before certification. In Laurel Heights II, a neighborhood

improvement association argued that in determining whether recirculation is

required, ―the ‗fair argument‘ test used to review the decision . . . to prepare a

negative declaration‖ in lieu of an EIR should apply. (Laurel Heights II, supra, 6

Cal.4th at p. 1134.) We disagreed, explaining: ―[S]ection 21151 commands that

an EIR must be prepared whenever a project ‗may have a significant effect on the

environment.‘ (Italics added.) In No Oil . . . , we interpreted section 21151 to

require preparation of an EIR whenever it can be fairly argued on the basis of

substantial evidence that the project may have significant environmental impact.

[Citation.] Our decision, however, expressly acknowledged that judicial review of

agency decisions under CEQA is governed by sections 21168 (administrative

mandamus) and 21168.5 (traditional mandamus) and, of course, did not purport to

alter the standard of review set forth in those statutes. Rather, the ‗fair argument‘

test was derived from an interpretation of the language of, and policies underlying,

section 21151 itself. For this reason, the ‗fair argument‘ test has been applied only

to the decision whether to prepare an original EIR or a negative declaration.

[Citations.] The Association has advanced no persuasive authority or reasons for

taking this test out of the context of the statutory language of section 21151 and

applying it to an agency‘s decision under section 21092.1. [¶] We conclude that

the substantial evidence standard set forth in section 21168.5 governs the

[agency‘s] decision not to recirculate the EIR in this case.‖ (Id. at pp. 1134-1135,

fns. omitted.)

Several courts, however, have extended the fair argument approach to

aspects of the determination whether the unusual circumstances exception applies.

(Voices for Rural Living v. El Dorado Irr. Dist. (2012) 209 Cal.App.4th 1096,

1108 (Voices); Wollmer v. City of Berkeley (2011) 193 Cal.App.4th 1329, 1350;

Banker’s Hill, supra, 139 Cal.App.4th at pp. 261-267; Azusa Land Reclamation

Co. v. Main San Gabriel Basin Watermaster (1997) 52 Cal.App.4th 1165, 1206;

Dunn-Edwards Corp. v. Bay Area Air Quality Management Dist. (1992) 9

Cal.App.4th 644, 654-656.) Other courts have noted judicial disagreement as to

whether the fair argument standard applies in this context, but have declined to

decide the issue, finding that the standard‘s application would not have affected

the result. (Save the Plastic Bag Coalition v. City and County of San Francisco

32



(2013) 222 Cal.App.4th 863, 879; Hines v. California Coastal Commission (2010)

186 Cal.App.4th 830, 855; San Lorenzo Valley Community Advocates for

Responsible Educ. v. San Lorenzo Valley Unified School Dist. (2006) 139

Cal.App.4th 1356, 1390; Santa Monica Chamber of Commerce v. City of Santa

Monica (2002) 101 Cal.App.4th 786, 796 (Santa Monica); Fairbank v. City of Mill

Valley (1999) 75 Cal.App.4th 1243, 1259-1260; Ukiah, supra, 2 Cal.App.4th at p.

728, fn. 7.) The principal supporting authority these courts cite for the fair

argument standard‘s inapplicability is Centinela Hospital Assn. v. City of

Inglewood (1990) 225 Cal.App.3d 1586. There, in rejecting the claim that the

unusual circumstances exception applied, the court reasoned: ―When appellant

argues that the facility is located ‗at an extremely sensitive location in terms of

public usage and traffic,‘ and it ‗will create a health and safety hazard, which in

turn, will place increased demands on public services such as police and fire

protection,‘ appellant is asking us to adopt an improper standard of review and

independently reweigh the evidence. We conclude that substantial evidence

supports the express findings of the [City of Inglewood Planning] Commission

and city council as to traffic and public health and safety issues and substantial

evidence supports the implied finding in the notice of exemption that the facility

would not cause any significant environmental effects.‖6 (Centinela, at p. 1601.)

We conclude that both prongs of section 21168.5‘s abuse of discretion

standard apply on review of an agency‘s decision with respect to the unusual

circumstances exception. The determination as to whether there are ―unusual

circumstances‖ (Guidelines, § 15300.2, subd. (c)) is reviewed under section

21168.5‘s substantial evidence prong. However, an agency‘s finding as to

also cite Dehne v. County of Santa Clara (1981) 115 Cal.App.3d 827, but that
decision does not mention or discuss the unusual circumstances exception.

33



whether unusual circumstances give rise to ―a reasonable possibility that the

activity will have a significant effect on the environment‖ (Guidelines, § 15300.2,

subd. (c)) is reviewed to determine whether the agency, in applying the fair

argument standard, ―proceeded in [the] manner required by law.‖ (§ 21168.5;

Friends of “B” Street, supra, 106 Cal.App.3d at p. 1002.)

Whether a particular project presents circumstances that are unusual for

projects in an exempt class is an essentially factual inquiry, ― ‗founded ―on the

application of the fact-finding tribunal‘s experience with the mainsprings of

human conduct.‖ ‘ ‖ (People v. Louis (1986) 42 Cal.3d 969, 987.) Accordingly,

as to this question, the agency serves as ―the finder of fact‖ (Save Our Peninsula

Committee v. Monterey County Board of Supervisors (2001) 87 Cal.App.4th 99,

117), and a reviewing court should apply the traditional substantial evidence

standard that section 21168.5 incorporates. (Save Our Peninsula Committee, at p.

117.) Under that relatively deferential standard of review, the reviewing court‘s

― ‗role‘ ‖ in considering the evidence differs from the agency‘s. (Western States

Petroleum Assn. v. Superior Court (1995) 9 Cal.4th 559, 576.) ― ‗Agencies must

weigh the evidence and determine ―which way the scales tip,‖ while courts

conducting [traditional] substantial evidence . . . review generally do not.‘ ‖

(Ibid.) Instead, reviewing courts, after resolving all evidentiary conflicts in the

agency‘s favor and indulging in all legitimate and reasonable inferences to uphold

the agency‘s finding, must affirm that finding if there is any substantial evidence,

contradicted or uncontradicted, to support it. (Id. at p. 571; see Laurel Heights

Improvement Assn. v. Regents of University of California (1988) 47 Cal.3d 376,

393 `(Laurel Heights I ) [reviewing court‘s ―task is not to weigh conflicting

evidence and determine who has the better argument‖ or whether ―an opposite

conclusion would have been equally or more reasonable‖].)

34



As to the whether there is ―a reasonable possibility‖ that an unusual

circumstance will produce ―a significant effect on the environment‖ (Guidelines,

§ 15300.2, subd. (c)), a different approach is appropriate, both by the agency

making the determination and by reviewing courts. As we explained in Laurel

Heights II, supra, 6 Cal.4th at pages 1134-1135, the fair argument standard ―was

derived from an interpretation of the language of, and policies underlying,‖ the

statute at issue in No Oil — section 21151 — which ―commands that an EIR must

be prepared whenever a project ‗may have a significant effect on the

environment.‘ ‖ (Italics omitted.) As the Court of Appeal observed in Banker’s

Hill, supra, 139 Cal.App.4th at page 264, there are ―close textual similarities‖

between this statutory language and the language of Guidelines section 15300.2,

subdivision (c), which precludes application of categorical exemptions ―where

there is a reasonable possibility that the activity will have a significant effect on

the environment due to unusual circumstances.‖ (Italics added.) Notably, we

observed in No Oil that ―the word ‗may‘ connotes a ‗reasonable possibility . . . .‘ ‖

(No Oil, supra, 13 Cal.3d at p. 83, fn. 16.) Accordingly, when there are ―unusual

circumstances,‖ it is appropriate for agencies to apply the fair argument standard

in determining whether ―there is a reasonable possibility of a significant effect on

the environment due to unusual circumstances.‖ (Guidelines, § 15300.2, subd.

(c).) As to this question, the reviewing court‘s function ―is to determine whether

substantial evidence support[s] the agency‘s conclusion as to whether the

prescribed ‗fair argument‘ could be made.‖ (Friends of “B” Street, supra, 106

Cal.App.3d at p. 1002.)

This bifurcated approach to the questions of unusual circumstances and

potentially significant effects comports with our construction of the unusual

circumstances exception to require findings of both unusual circumstances and a

potentially significant effect. It would be inappropriate for an agency to apply the

35



fair argument standard to determine whether unusual circumstances exist. That

standard is intended to guide the determination of whether a project has a

potentially significant effect, not whether it presents unusual circumstances.

While evidence of a significant effect may be offered to prove unusual

circumstances, circumstances do not become unusual merely because a fair

argument can be made that they might have a significant effect. Evidence that a

project may have a significant effect is not alone enough to remove it from a class

consisting of similar projects that the Secretary has found ―do not have a

significant effect on the environment.‖ (§ 21084, subd. (a), italics added; cf.

Laurel Heights II, supra, 6 Cal.4th at p. 1134; No Oil, supra, 13 Cal.3d at p. 83,

fn. 16 .) Therefore, an agency must weigh the evidence of environmental effects

along with all the other evidence relevant to the unusual circumstances

determination, and make a finding of fact. Judicial review of such determinations

is limited to ascertaining whether they are ―supported by substantial evidence.‖

(§ 21168.5.)

On the other hand, when unusual circumstances are established, the

Secretary‘s findings as to the typical environmental effects of projects in an

exempt category no longer control. Because there has been no prior review of the

effects of unusual circumstances, the policy considerations we discussed in No Oil

apply. An agency must evaluate potential environmental effects under the fair

argument standard, and judicial review is limited to determining whether the

agency applied the standard ―in [the] manner required by law.‖ (§ 21168.5.)

We reject respondents‘ assertion that applying two different standards to

the unusual circumstances exception is ―fundamentally inconsistent with the legal

framework for categorical exemptions‖ and would, by making the process ―too

complicated and cumbersome,‖ ―defeat the Legislature‘s intent in having

categorical exemptions.‖ As explained above, requiring an agency to apply the

36



fair argument standard to determine whether unusual circumstances give rise to ―a

reasonable possibility that the activity will have a significant effect on the

environment‖ (Guidelines, § 15300.2, subd. (c)) is fully consistent with CEQA‘s

framework and the Legislature‘s intent to provide categorical exemptions. Nor,

for a reviewing court, is there anything particularly ―complicated‖ or

―cumbersome‖ about applying section 21168.5‘s substantial evidence prong to

unusual circumstance determinations, and its ―proceeded in a manner required by

law‖ prong to determinations as to potentially significant effects. Courts are well

versed in bringing a variety of considerations to bear in making such

determinations.

Contrary to respondents‘ assertion, applying the fair argument standard to

aspects of the unusual circumstances exception does not conflict with our decision

in Muzzy Ranch, supra, 41 Cal.4th 372. The premise of respondents‘ argument is

that, in Muzzy Ranch, we applied the traditional substantial evidence test in

reviewing an agency‘s determination under Guidelines section 15061, subdivision

(b)(3), that a proposed project was not subject to CEQA. However, in Muzzy

Ranch, we had no occasion to identify the standard of review we applied.

Moreover, as appellants explain, the language of Guidelines section 15061,

subdivision (b)(3), is considerably different from the language of the unusual

circumstances exception; the former applies ―[w]here it can be seen with certainty

that there is no possibility that the activity in question may have a significant

effect on the environment‖ (Guidelines, § 15061, subd. (b)(3)), whereas the latter

applies ―where there is a reasonable possibility that the activity will have a

significant effect on the environment due to unusual circumstances‖ (Guidelines, §

15300.2, subd. (c)). Thus, even under respondents‘ reading of Muzzy Ranch,

applying the fair argument standard in the context of the unusual circumstances

exception creates no conflict with that decision.

37



Finally, and again contrary to respondents‘ assertion, our approach is fully

consistent with — and is, indeed, affirmatively supported by — the decision in

Valley Advocates v. City of Fresno (2008) 160 Cal.App.4th 1039. At issue there

were the following CEQA provisions: (1) section 21084.1, which provides that

―[a] project that may cause a substantial adverse change in the significance of an

historical resource is a project that may have a significant effect on the

environment‖; (2) section 21084, subdivision (e), which provides that ―[a] project

that may cause a substantial adverse change in the significance of a historical

resource, as specified in Section 21084.1, shall not be exempted from [CEQA]

pursuant to subdivision (a)‖; and (3) Guidelines section 15300.2, subdivision (f),

which provides that ―[a] categorical exemption shall not be used for a project

which may cause a substantial adverse change in the significance of a historical

resource.‖ The court held that, in applying these provisions, ―the fair argument

standard does not govern‖ an agency‘s determination of whether a building

qualifies as a ―historical resource.‖ (Valley Advocates, supra, at p. 1072.)

However, the court continued, ―once the resource has been determined to be an

historical resource, then the fair argument standard applies to the question whether

the proposed project ‗may cause a substantial adverse change in the significance of

an historical resource‘ [citation] and thereby have a significant effect on the

environment.‖ (Ibid.) This discussion supports the conclusion that, if ―unusual

circumstances‖ are established, an agency should apply the fair argument standard

in determining whether there is ―a reasonable possibility‖ that those circumstances

will produce ―a significant effect‖ within the meaning of CEQA. (Guidelines, §

15300.2, subd. (c).)

C. Lower Court Rulings.

In reviewing the City‘s determination that the unusual circumstances

exception does not apply, the trial court identified and made ―two separate

38



determinations‖: (1) whether ―there is a reasonable possibility that the activity

will have a significant effect on the environment‖; and (2) ―whether such

reasonable possibility of a significant effect is due to unusual circumstances

associated with the project.‖ It answered the first question in the affirmative,

explaining in part that, ―[d]espite Respondents‘ criticisms of [Karp‘s] report and

[his] methodology, and even when discounting the clearly erroneous and

misleading portions, Dr. Karp‘s opinion‖ regarding the ― ‗probability of seismic

lurching of oversteepened side-hill fills‘ ‖ ―provides substantial evidence of a fair

argument of a significant environmental effect consequent to the Project.‖

However, the court also found that the proposed project did not present ―unusual

circumstances,‖ explaining: ―Though the Project involves a large house, built in

the hills on a steep slope, there is nothing so out of the ordinary about such a

project that it would take it out of the exemption. Moreover, there is no evidence

to support a finding that any of the circumstances surrounding the Project make it

‗unusual.‘ . . . [T]hough it is a large house proposed to be built on a large and steep

hillside lot with grading and retaining walls, the Project is not so unusual for a

single family residence, particularly in this vicinity, as to constitute the type of

unusual circumstances required to support application of this exception.‖

In reversing the judgment, the Court of Appeal agreed with the trial court

―that Karp‘s letters . . . amounted to substantial evidence of a fair argument that

the proposed construction would result in significant environmental impacts.‖ But

it disagreed that the unusual circumstances exception applies only if the proposed

project‘s potentially significant environmental effects are due to unusual

circumstances. In the Court of Appeal‘s view, ―the fact‖ that the proposed project

―may‖ have a significant effect on the environment ―is itself an unusual

circumstance‖ that ―preclude[s]‖ the City from applying a categorical exemption.

The Court of Appeal went on to note that it may nevertheless ―be helpful‖ to

39



determine ―whether unusual circumstances exist‖ apart from the project‘s

potentially significant environmental effect. Considering this question de novo, it

found that, with respect to the Class 3 small structure exemption, the proposed

project‘s size constitutes such a circumstance. In reaching this result, it reasoned

that ―whether a circumstance is unusual ‗is judged relative to the typical

circumstances related to an otherwise typically exempt project,‘ as opposed to the

typical circumstances in one particular neighborhood.‖ As to the Class 32 in-fill

development exemption, the court offered no additional analysis.

It is apparent that neither the trial court nor the Court of Appeal applied

principles like those we have set out above. Remand for application of the

standards we announce today is therefore both appropriate and necessary.7

The Court of Appeal erred in another respect by indicating, as noted above,

that the unusual circumstances inquiry excludes consideration of ―the typical

circumstances in one particular neighborhood.‖ In a number of decisions, our

appellate courts have looked to conditions in the immediate vicinity of a proposed

project to determine whether the unusual circumstances exception applied.

(Bloom v. McGurk (1994) 26 Cal.App.4th 1307, 1315-1316; City of Pasadena v.

State of California (1993) 14 Cal.App.4th 810, 826-827; Ukiah, supra, 2

Cal.App.4th at p. 736.) Indeed, in the only decision the Court of Appeal cited for

its contrary view — Santa Monica, supra, 101 Cal.App.4th 786 — the court


7

In reversing based on potential geotechnical effects, the Court of Appeal

did not address other potential effects appellants allege, including aesthetic and
view impacts, inconsistencies with land use plans and policies the City has
adopted for environmental protection, construction-related traffic impacts, and
permanent traffic impacts related to contemplated fundraising activities at the
house. Nor did the Court of Appeal address appellants‘ argument that the City‘s
adoption of a traffic management plan is a mitigation measure that precludes a
finding that the proposed project is categorically exempt. Rather than address
these issues here in the first instance, we leave their consideration to the Court of
Appeal on remand.

40



quoted Ukiah on this point and declared it to be ―instructive.‖ (Santa Monica, at

p. 802.) Insofar as these decisions indicate that local conditions are relevant, we

agree. In determining whether the environmental effects of a proposed project are

unusual or typical, local agencies have discretion to consider conditions in the

vicinity of the proposed project.

Respondents separately attack the conclusion of both the trial court and the

Court of Appeal that Karp‘s submissions constitute substantial evidence of a fair

argument that the proposed project may have a significant environmental effect.

As earlier noted, Karp opined that the proposed project ―is likely to have very

significant environmental impacts . . . due to the probability of seismic lurching of

the oversteepened side-hill fills.‖ Respondents contend that Karp‘s opinion does

not constitute substantial evidence of a fair argument because it is based on a

misreading of the plans the City approved. In their view, the evidence in the

record, including the submissions of Kropp and Toby, conclusively establishes

that ―the project approved by the City does not involve ‗side-hill fill‘ ‖ and that

Karp was mistaken in reading the plans otherwise. Because of Karp‘s erroneous

belief there would be side-hill fill, his opinion, respondents assert, ―is not

substantial evidence.‖ A finding of potential environmental impacts, respondents

argue, must be based on the proposed project as actually approved, and may not be

based on unapproved activities that opponents assert will be necessary because the

project as approved cannot be built. If the proposed project ―cannot be built as

approved‖ and applicants want to build a different project, then ―they must return

to the City for approval of a different project and the City could issue a stop-work

notice to prevent unauthorized construction.‖

We agree with respondents that a finding of environmental impacts must be

based on the proposed project as actually approved and may not be based on

unapproved activities that opponents assert will be necessary because the project,

41



as approved, cannot be built. In Laurel Heights I, supra, 47 Cal.3d at page 395,

we considered whether there are circumstances under which an EIR must address

―future action related to‖ a proposed project. There, the University of California,

San Francisco (UCSF), had certified an EIR for moving its school of pharmacy to

100,000 square feet of a 354,000-square-foot building it had purchased. (Id. at p.

393.) Although UCSF admitted it intended to use the remainder of the building

when existing tenants left, the EIR it prepared did not consider the potential

environmental effect of that intended future use. (Id. at pp. 393, 397.) To justify

this omission, UCSF argued that it had ―not formally decided precisely how [it

would] use the remainder of the building.‖ (Id. at p. 396.) In rejecting this

argument, we first held that an EIR for a proposed project must consider the

potential environmental effects of future expansion if expansion (1) ―is a

reasonably foreseeable consequence of the initial project‖ and (2) ―will be

significant in that it will likely change the scope or nature of the initial project or

its environmental effects.‖ (Ibid.) This standard, we reasoned, properly balances

the following considerations: (1) delayed review may produce ―bureaucratic and

financial momentum‖ that ―provid[es] a strong incentive to ignore environmental

concerns that could be dealt with more easily at an early stage of the project‖ (id.

at p. 395); (2) ― ‗environmental considerations do not become submerged by

chopping a large project into many little ones — each with a minimal potential

impact on the environment — which cumulatively may have disastrous

consequences‘ [citation]‖; and (3) ―premature environmental analysis may be

meaningless and financially wasteful‖ (id. at p. 396). We then concluded that

UCSF‘s EIR had to address the potential effects of future use because there was

―telling evidence‖ UCSF had, by the time it prepared the EIR, ―either made

decisions or formulated reasonably definite proposals as to future uses of the

building.‖ (Id. at p. 397.) We clarified, however, that an EIR need not discuss

42



―specific future action that is merely contemplated or a gleam in a planner‘s eye.‖

(Id. at p. 398.)

We decline to extend Laurel Heights I to situations where project

opponents claim, not that the proposed project will lead to additional future

development, but that the proposed project cannot be carried out as approved and

will require additional work that may or will have a significant environmental

effect. The latter situation, unlike the former, presents little risk of either

bureaucratic and financial impediments to proper environmental review or

piecemeal review of a project with the potential for significant cumulative effects.

As respondents argue, if a proposed project cannot be built as approved, then the

project‘s proponents will have to seek approval of any additional activities and, at

that time, will have to address the potential environmental effects of those

additional activities. As respondents also argue, if a project opponent‘s opinion

that unapproved activities may have a significant environmental effect constitutes

fair argument, then it is doubtful that any project could survive challenge.

Accordingly, Karp‘s opinion is insufficient as a matter of law insofar as it is based

on the potential effect of unapproved activities Karp believes will be necessary

because the project cannot be built as approved.

This conclusion has implications for respondents‘ claim that, because Karp

misread the proposed project‘s plans, his opinion is legally insufficient. As part of

the permit application, applicants submitted a set of architectural plans for the

project. In opining that the proposed project would result in ―oversteepened side-

hill fills‖ with potentially significant environmental effects — including ―seismic

lurching‖ — Karp relied largely, if not entirely, on a page of those plans entitled

―TRANSVERSE SECTION LOOKING EAST.‖ In April 2010, during the appeal

to the city council, Karp stated that this page ―indicates [that] fills [will be] placed

directly on very steep existing slopes,‖ ―creat[ing] a new slope more than 50º.‖

43



However, the plans the Board had already approved three months earlier (along

with the use permit) did not include this page. Nor, as appellants concede, do the

project plans the city council ultimately approved include this page.8 Insofar as

Karp thus based his opinion regarding the project‘s potential effects on side-hill

fill that has not been approved, his opinion is legally insufficient.9 On remand, the

Court of Appeal should apply these principles to Karp‘s opinion should it reach

that point in its analysis.10

Finally, because reversal and remand is appropriate for reasons explained

above, we need not resolve respondents‘ claim that the remedy the Court of

Appeal chose upon finding the proposed project not to be exempt under Class 3 or

Class 32 — ordering preparation of an EIR — was improper. However, it is

appropriate to discuss that issue because the question of remedy could arise again

on remand.

Section 21168.9 specifically addresses the available remedies for CEQA

violations. As here relevant, subdivision (a) provides that, upon finding that a


8

In its resolution affirming the Board‘s decision, the city council stated:

―[T]he Council hereby adopts . . . the project plans on Exhibit B.‖ The page on
which Karp relied does not appear in that exhibit.
9

Based on other expert evidence before the city council — the letters from

Kropp and Toby — respondents also assert that Karp misread the omitted page,
and that what he identified on that page as side-hill fill is actually nothing more
than the lot‘s current ground surface. In light of our conclusion, we need not
address this argument.
10

Respondents also argue that the ―the probability of seismic lurching‖ Karp

identified is an effect, not of the project, but of Berkeley‘s ―existing earthquake-
prone environment,‖ and that application of the unusual circumstances exception
may not be based on evidence of the existing environment‘s impact on a proposed
project. In California Building Industry Assn. v. Bay Area Air Quality
Management Dist.
(review granted Nov. 26, 2013, S213478), we granted review to
decide whether CEQA requires an analysis of how existing environmental
conditions will impact future residents or users of a proposed project. Given this
fact, and the other errors that require reversal and remand, we do not address this
claim.

44



public agency‘s decision violates CEQA, a court should enter an order that

includes (1) a mandate that the decision be voided in whole or in part, and/or (2) a

mandate that the agency ―take specific action as may be necessary to bring

the . . . decision into compliance with‖ CEQA. (§ 21168.9, subd. (a)(1), (3).)

Subdivision (b) states that any such order ―shall be made by the issuance of a

peremptory writ of mandate specifying what action by the public agency is

necessary to comply with [CEQA].‖ (§ 21168.9, subd. (b), italics added.)

Consistent with these provisions, we have ordered preparation of an EIR upon

finding that a public agency had improperly issued a negative declaration for a

proposed project (Communities for a Better Environment v. South Coast Air

Quality Management Dist. (2010) 48 Cal.4th 310, 320), and upon finding that a

certified EIR was inadequate (Laurel Heights I, supra, 47 Cal.3d at p. 388).

However, as respondents note, subdivision (c) of section 21168.9 provides

in part that ―[n]othing in this section authorizes a court to direct any public agency

to exercise its discretion in any particular way.‖ In Voices, supra, 209

Cal.App.4th at page 1113, the Court of Appeal held that, upon finding that an

agency erred in applying a categorical exemption, the trial court had ―exceeded its

authority‖ in ordering the agency to prepare an EIR. ―How an agency complies

with CEQA,‖ the Court of Appeal reasoned, ―is a matter first left to the agency‘s

discretion. Having determined the project was not exempt from CEQA, the court

should have ordered [the agency] to proceed with further CEQA compliance,

which in this case would have been the preparation of an initial study and a

determination of whether further environmental review would require an EIR or a

mitigated negative declaration.‖ (Ibid.) Consistent with these authorities, if, on

remand, the Court of Appeal determines that neither of the categorical exemptions

discussed above applies, then it may order preparation of an EIR only if, under the

45



circumstances, the City would lack discretion to apply another exemption or to

issue a negative declaration, mitigated or otherwise.

III. DISPOSITION

The Court of Appeal‘s judgment is reversed and the matter is remanded for

further proceedings consistent with this opinion.

CONCURRING OPINION BY LIU, J.




I agree with today‘s opinion that ―a finding of environmental impacts must

be based on the proposed project as actually approved and may not be based on

unapproved activities that opponents assert will be necessary because the project,

as approved, cannot be built.‖ (Maj. opn., ante, at p. 42.) This rule will not lead

to evasion of the environmental review requirements of the California

Environmental Quality Act (CEQA) because presumably a developer‘s failure to

build the project as approved will be remedied by the local agency that approved

the project. Where opponents of a project make a credible argument that it cannot

be built as approved, a trial court may exercise its discretion to retain continuing

jurisdiction after rendering a judgment in order to ensure CEQA compliance. (See

2 Witkin, Cal. Procedure, Jurisdiction, § 420, pp. 1070–1071; City of Pasadena v.

City of Alhambra (1949) 33 Cal.2d 908, 936 [court reserves jurisdiction to modify

water rights judgment ― ‗in the event material change be found or any such

abandonment or forfeiture be established‘ ‖].) In this case, because the trial court

and Court of Appeal did not limit environmental review to projects actually

approved, I agree that reversal and remand are warranted. (Maj. opn., ante, at

pp. 41–44.)

I do not agree, however, with the court‘s reading of section 15300.2,

subdivision (c) of the CEQA guidelines (Cal. Code Regs., tit. 14, § 15000 et seq.

1



(Guidelines)) or with the court‘s novel and unnecessarily complicated approach to

the standard of review. Section 15300.2, subdivision (c) (hereafter

section 15300.2(c)) provides that a categorical exemption from CEQA review

shall not apply when ―there is a reasonable possibility that the activity will have a

significant effect on the environment due to unusual circumstances.‖ The court

says this language establishes two distinct requirements for section 15300.2(c)‘s

applicability: (1) there must be a reasonable possibility the project will have

significant environmental effects and (2) those effects must be due to unusual

circumstances. But, as explained below, a project falling within a categorical

exemption is, by definition, a project belonging to a class of projects that does not

have significant environmental effects. (See Pub. Resources Code, § 21084,

subd. (a).) When there is a reasonable possibility that a project otherwise covered

by a categorical exemption will have a significant environmental effect, it

necessarily follows that the project presents unusual circumstances. In other

words, the reasonable possibility of a significant environmental effect means that

some circumstance of the project is not usual in comparison to the typical project

in the exempt category. Instead of comprising a distinct requirement, the phrase

―unusual circumstances‖ in section 15300.2(c) simply describes the nature of a

project that, while belonging to a class of projects that typically have no

significant environmental effects, nonetheless may have such effects. The sole

question for courts reviewing agency determinations under section 15300.2(c) is

whether substantial evidence supports a fair argument that the project will have

significant environmental effects.

It is unfortunate that today‘s opinion, instead of simplifying the law in

accordance with the CEQA statute and guidelines, adds further complexity to an

area that many courts, practitioners, and citizens already find difficult to navigate.

Nevertheless, I expect that after today‘s decision, as before, courts reviewing

2



agency determinations under section 15300.2(c) will be guided by that guideline‘s

basic purpose, which echoes the statutory mandate: to ensure that projects with a

reasonable possibility of significant environmental effects are not exempted from

CEQA review.

I.

The main purpose of environmental review under CEQA is to ―identify the

significant effects on the environment of a project‖ and to identify project

alternatives and feasible mitigation measures. (Pub. Resources Code, § 21002.1,

subd. (a); all statutory references are to this code unless otherwise indicated.)

Consistent with that purpose, the Legislature created categorical exemptions and

directed the Secretary of the Natural Resources Agency (the Secretary) to list

classes of projects exempt from CEQA review. Section 21084, subdivision (a)

(hereafter section 21084(a)) provides: ―The guidelines prepared and adopted

pursuant to Section 21083 shall include a list of classes of projects that have been

determined not to have a significant effect on the environment and that shall be

exempt from this division. In adopting the guidelines, the Secretary of the Natural

Resources Agency shall make a finding that the listed classes of projects referred

to in this section do not have a significant effect on the environment.‖ (Italics

added.) Thus, section 21084(a) instructs the Secretary to exempt from CEQA

review only classes of projects that do not have a significant effect on the

environment.

The exempt classes of projects listed by the Secretary stand in contrast to

statutory exemptions created by the Legislature. The latter include certain kinds

of affordable housing (§ 21159.23), certain high priority transit projects

(§ 21155.1), and the construction of certain prisons (§§ 21080.01, 21080.02). The

statutory exemptions are not based on any determination that the exempt projects

will not have significant environmental effects. Instead, they are based on the

3



Legislature‘s determination that each of the exemptions ―promote[s] an interest

important enough to justify forgoing the benefits of environmental review.‖

(Napa Valley Wine Train, Inc. v. Public Utilities Com. (1990) 50 Cal.3d 370, 382.)

The categorical exemptions authorized by section 21084(a) are fundamentally

different. They are not based on a judgment that certain categories of projects

should be exempt despite their potential effect on the environment. They are

based on a wholesale judgment that projects within the exempt category will not

have significant environmental effects.

The fact that a categorical exemption reflects a wholesale judgment about a

class of projects, and not an individual judgment about a particular project, gives

rise to the interpretive question before us. A class of projects ―determined not to

have a significant effect on the environment‖ (§ 21084(a)) — for example, a

single-family residence — may turn out to be overinclusive insofar as it includes

some projects that fit the category but nevertheless may have significant

environmental effects. How are such outliers to be treated under the CEQA

scheme?

One approach would be to say that section 21084(a) permits such

overinclusion because most projects in an exempt class will not have significant

environmental effects and the efficiency gains of exempting the entire class

outweigh the value of requiring CEQA review of the few projects in the class that

may have significant effects. But neither the court nor any party has advanced this

theory, and for good reason.

In Wildlife Alive v. Chickering (1976) 18 Cal.3d 190, 205–206

(Chickering), we said that ―no regulation is valid if its issuance exceeds the scope

of the enabling statute. [Citations.] The [S]ecretary is empowered to exempt only

those activities which do not have a significant effect on the environment. (Pub.

Resources Code, § 21084.) It follows that where there is any reasonable

4



possibility that a project or activity may have a significant effect on the

environment, an exemption would be improper.‖ Section 15300.2(c), promulgated

shortly after Chickering, was an attempt to codify Chickering and its

understanding of section 21084(a). A portion of section 15300.2‘s rulemaking file

reproduced by appellants confirms this regulatory intent, and respondents do not

suggest otherwise. (See 1 Kostka & Zischke, Practice Under the California

Environmental Quality Act (2d ed. 2008) § 5.72, p. 5-62 (1 Kostka & Zischke)

[§ 15300.2(c) ―adopted to codify the court‘s ruling‖ in Chickering that the

Secretary ―may exempt only activities that do not have a significant effect on the

environment‖]; Communities for a Better Environment v. California Resources

Agency (2002) 103 Cal.App.4th 98, 129 (Communities for a Better Environment)

[§ 15300.2(c) exception to categorical exemptions was ―based on the Chickering

decision‖].)

Section 15300.2(c) reads in full: ―Significant Effect. A categorical

exemption shall not be used for an activity where there is a reasonable possibility

that the activity will have a significant effect on the environment due to unusual

circumstances.‖ This language is one of six provisions under the heading

―Exceptions‖ in section 15300.2 of the CEQA guidelines. Like section

15300.2(c), each of the other five provisions makes the categorical exemptions

authorized by section 21084(a) inapplicable to projects that, while belonging to an

exempt class, have certain characteristics that raise environmental concerns. (See

§§ 15300.2, subd. (a) [exception for ―a project . . . ordinarily insignificant in its

impact on the environment [that] may in a particularly sensitive environment be

significant‖], 15300.2, subd. (b) [exception for ―successive projects of the same

type in the same place‖ whose ―cumulative impact . . . over time is significant‖],

15300.2, subd. (d) [exception for ―a project which may result in damage to scenic

resources . . . within . . . a state scenic highway‖], 15300.2, subd. (e) [exception for

5



a project located on a hazardous waste site], 15300.2, subd. (f) [exception for a

project that may adversely affect a historical resource].)

This regulatory structure — categorical exemptions, with various

exceptions to the exemptions — confirms that ―a categorical exemption authorized

by CEQA section 21084 is an exemption from CEQA for a class of projects that

the Resources Agency determines will generally not have a significant effect on

the environment.‖ (Communities for a Better Environment, supra, 103

Cal.App.4th at p. 127; see Azusa Land Reclamation Co. v. Main San Gabriel

Basin Watermaster (1997) 52 Cal.App.4th 1165, 1206 (Azusa) [a categorical

exemption identifies ―a class of activities that does not normally threaten the

environment‖ (italics added)].) The CEQA guidelines anticipate the

overinclusivity of categorical exemptions and address the problem by establishing

a list of exceptions.

In construing section 15300.2(c), it is worth noting that the title of the

provision is ―Significant Effect.‖ Hence I shall refer to section 15300.2(c) as the

―significant effect exception.‖ In calling section 15300.2(c) the ―unusual

circumstances exception,‖ today‘s opinion ignores the title and places primary

emphasis on a term that the provision itself does not emphasize.

As the court acknowledges, the term ―unusual circumstances‖ first

appeared in the context of CEQA review in Friends of Mammoth v. Board of

Supervisors (1972) 8 Cal.3d 247 (Friends of Mammoth), and this usage is key to

understanding section 15300.2(c). In Friends of Mammoth, we said that ―common

sense tells us that the majority of private projects for which a government permit

or similar entitlement is necessary are minor in scope — e.g., relating only to the

construction, improvement, or operation of an individual dwelling or small

business — and hence, in the absence of unusual circumstances, have little or no

effect on the public environment. Such projects, accordingly, may be approved

6



exactly as before the enactment of the [CEQA].‖ (Id. at p. 272, italics added.) We

did not suggest that a finding of ―unusual circumstances‖ was a prerequisite to

CEQA review. Rather, we used that phrase in the course of acknowledging that

private projects generally do not have significant effects on the environment, and

so when they do, such effects will be due to unusual circumstances. Reading

―unusual circumstances‖ in this straightforward manner squares section

15300.2(c) with both Friends of Mammoth and Chickering.

This understanding of ―unusual circumstances‖ is restated in Communities

for a Better Environment, supra, 103 Cal.App.4th 98, a case concerning the in-fill

development exemption under section 15332 of the CEQA guidelines. In

explaining that environmental effects not mentioned in section 15332, such as

aesthetics or health and safety impacts, must be considered in determining the

exemption‘s applicability, the court said: ―These other environmental effects . . .

would constitute ‗unusual circumstances‘ under this exception for a project that

otherwise meets the Guidelines section 15332 criteria. This is because a project

that does meet the comprehensive environmentally protective criteria of section

15332 normally would not have other significant environmental effects; if there

was a reasonable possibility that the project would have such effects, those effects

would be ‗unusual circumstances‘ covered by the section 15300.2, subdivision (c)

exception.‖ (Communities for a Better Environment, at p. 129.)

In sum, when there is a reasonable possibility of a significant

environmental effect from a project belonging to a class that generally does not

have such effects, the project necessarily presents ―unusual circumstances,‖ and

section 15300.2(c) applies.

7



II.

Today‘s opinion objects that this reading of section 15300.2(c) would result

in categorically exempt projects being treated the same as nonexempt projects,

thereby undermining the purpose of categorical exemptions. ―Try as they might,‖

the court says, ―appellants can identify no purpose or effect of the categorical

exemption statutes if, as they assert, a showing of potential environmental effect

precludes application of all categorical exemptions.‖ (Maj. opn., ante, at p. 16.)

―[T]o establish the unusual circumstances exception, it is not enough for a

challenger merely to provide substantial evidence that the project may have a

significant effect on the environment, because that is the inquiry CEQA requires

absent an exemption. (§ 21151.) Such a showing is inadequate to overcome the

Secretary‘s determination that the typical effects of a project within an exempt

class are not significant for CEQA purposes.‖ (Id. at pp. 20–21.) The court is thus

led to conclude that the term ―due to unusual circumstances‖ sets forth a

requirement separate and distinct from ―a reasonable possibility of significant

effects‖ in section 15300.2(c). In turn, the court devises a novel ―bifurcated‖

standard of review that evaluates whether there is a reasonable possibility of a

significant environmental effect under the fair argument standard, while evaluating

whether significant effects are due to unusual circumstances under a deferential

substantial evidence standard. (Maj. opn., ante, at pp. 34–37.) This approach, the

court suggests, is necessary in order to treat categorically exempt projects

differently from nonexempt projects and thereby realize the purpose of categorical

exemptions.

But the major premise of the court‘s reasoning is faulty, for there are two

reasons why it is not true that categorical exemptions would have no value if we

interpret section 15300.2(c) to apply whenever there is a reasonable possibility of

significant environmental effects.

8



First, when an agency has determined that a project falls within an exempt

category, the project enjoys a considerable procedural advantage. For any project

not covered by a categorical or other exemption, the reviewing agency has the

burden of conducting an initial study into whether the project will have significant

environmental effects. (See Guidelines, § 15063, subd. (a).) The project may

proceed without further environmental review only if the agency issues a negative

declaration identifying the project‘s environmental effects and explaining why

they are not significant. (See id., § 15063, subd. (b)(2); 1 Kostka & Zischke,

supra, § 6.2, pp. 6-6 to 6-7.) Notice and public review and comment are required

of a negative declaration, and an agency must consider comments and potentially

modify its conclusions in response to those comments. (See 1 Kostka & Zischke,

supra, §§ 7.10, pp. 7-9 to 7-10; 7.19, pp. 7-16 to 7-17.)

By contrast, an agency finding that a project falls into an exempt category

need not follow any particular procedure nor include any written determination,

and the agency need not undertake an initial study or adopt a negative declaration.

(See 1 Kostka & Zischke, supra, § 5.114, pp. 5-100 to 5-101.) When an agency

finds that a project is subject to a categorical exemption, it impliedly finds that it

has no significant environmental effect, and the burden shifts to the challengers of

the proposed project to produce evidence that the project will have a significant

effect. (Id. at § 5.71, pp. 5-61 to 5-62 and cases cited therein.) Once an agency

finds a project categorically exempt, it is the project opponent‘s burden to produce

evidence that the significant effect exception applies.

This procedural advantage should not be underestimated. In many cases,

categorical exemptions are not litigated, and the applicability of the exemption is

evident. In the mine run of cases, the efficiency gains of sparing the agency the

task of conducting an initial study and issuing a negative declaration provide a

strong policy justification for categorical exemptions. Moreover, as is generally

9



true of burden allocations in the law, in cases where an exemption‘s applicability

presents a close issue, requiring the challenger to show the reasonable possibility

of a significant effect, instead of requiring the agency to show no such effects, can

be determinative.

The court says this procedural advantage is ―largely illusory‖ because ―an

agency may not apply a categorical exemption without considering evidence in its

files of potentially significant effects, regardless of whether that evidence comes

from its own investigation, the proponent‘s submissions, a project opponent, or

some other source.‖ (Maj. opn., ante, at p. 18.) But an agency‘s obligation to

consider evidence in its files of potentially significant effects can hardly be

equated with an agency‘s obligation, in the case of a nonexempt project, to

undertake an initial study of the project‘s environmental effects, to solicit and

consider public comments on the study, and to issue a negative declaration

explaining why potential environmental impacts would not be significant. The

procedural burdens falling on agencies when they review nonexempt projects are

considerably greater than when they review categorically exempt projects. The

court‘s suggestion to the contrary will certainly come as news to the agencies that

undertake these different review procedures.

Moreover, an agency finding that a project falls into an exempt category

confers a second advantage. As the court observes, the Secretary had to interpret

the meaning of ―significant effects‖ in order to identify classes of projects with no

significant effects pursuant to section 21084(a). The Secretary‘s designation of an

exempt category reflects a judgment that projects in the category typically do not

have significant environmental effects, and this judgment is entitled to

considerable weight. When an opponent seeks to subject such a project to CEQA

review, the proponent can make two comparative arguments (assuming they are

supported by evidence) that are unavailable in the case of a nonexempt project.

10



First, the proponent can argue that the project‘s effects are typical of the effects

generated by projects in the exempt category, such that few or no projects in the

category would be exempt if the effects were deemed significant. Second, the

proponent can argue that the project‘s dimensions or features are not unusual

compared to typical projects in the exempt category, thereby suggesting that the

project is similar to those that the Secretary has determined not to have a

significant environmental effect. The availability of these arguments shows that

the phrase ―due to unusual circumstances‖ is not ―meaningless surplusage.‖ (Maj.

opn., ante, at p. 20.) Such arguments make it more likely that a project belonging

to an exempt category will be able to bypass the environmental review that would

otherwise be required in the absence of any categorical exemption. (See, e.g., San

Francisco Beautiful v. City and County of San Francisco (2014) 226 Cal.App.4th

1012, 1025 (San Francisco Beautiful); Fairbank v. City of Mill Valley (1999) 75

Cal.App.4th 1243, 1260 (Fairbank); Association for Protection of Environmental

Values in Ukiah v. City of Ukiah (1991) 2 Cal.App.4th 720, 736 (Ukiah).

The court says this advantage is also ―illusory‖ because ―evidence a project

proponent offers to show that the project will only have typical effects,

dimensions, and features is irrelevant if a project opponent can make a mere fair

argument that those effects, dimensions, or features are not typical, or that the

project will have a significant environmental effect.‖ (Maj. opn., ante, at p. 19.)

But evidence of typicality is surely relevant to whether a project opponent can

make a fair argument of atypical features or significant effects. This is confirmed

by the cases just cited (San Francisco Beautiful, Fairbank, and Ukiah), each of

which relies on such comparative arguments in finding no substantial evidence of

a fair argument of significant effects. The court nowhere suggests these cases

erred in their reasoning or results. The fact that comparative arguments may not

11



always defeat a fair argument of significant effects does not negate their value in

the cases where they do.

Today‘s opinion also contends that my reading of section 15300.2(c) puts a

project proponent who claims a categorical exemption in the same position as the

proponent of a nonexempt project who claims the common sense exemption in

Guidelines section 15061, subdivision (b)(3). (Maj. opn., ante, at p. 17.) But the

common sense exemption is available only when the agency, based on the record

evidence, meets its burden of demonstrating ―with certainty that there is no

possibility that the activity in question may have a significant effect on the

environment.‖ (Guidelines, § 15061, subd. (b)(3), italics added; see Muzzy Ranch

Co. v. Solano County Airport Land Use Com. (2007) 41 Cal.4th 372, 386–387.)

This exacting requirement exceeds an agency‘s obligation, before applying a

categorical exemption, to consider the evidence in its files and preliminarily rule

out a reasonable possibility of significant effects. Indeed, if an agency could

apply the common sense exemption to a project not covered by a categorical

exemption simply by making a preliminary determination based on evidence in its

files that there is no reasonable possibility of significant effects, then the common

sense exemption would swallow the general rule that an agency must conduct an

initial study to determine whether a project not covered by a categorical exemption

will have significant effects. (See Guidelines, § 15063, subd. (a).)

An agency may find that a project falls within a categorical exemption

without first making an express or definitive finding that no section 15300.2

exception applies; the burden is on the party challenging the categorical exemption

to show that an exception applies. (Committee to Save Hollywoodland Specific

Plan v. City of Los Angeles (2008) 161 Cal.App.4th 1168, 1186–1187.) In

addition, project proponents seeking to invoke a categorical exemption may

employ comparative arguments that are not available to project proponents

12



seeking to invoke the common sense exemption. Thus, the availability of the

common sense exemption for projects meeting its narrow standard of ―certainty‖

does not negate the advantages that a categorical exemption confers.

The court is thus mistaken that the categorical exemption statutes have ―no

purpose or effect . . . if . . . a showing of potential environmental effect precludes

application of all categorical exemptions.‖ (Maj. opn., ante, at p. 16.) Without

this erroneous premise, there is no reason to construe ―due to unusual

circumstances‖ as an independent requirement in section 15300.2(c) or to adopt a

separate standard of review for the determination of ―unusual circumstances.‖ As

explained above, this approach is at odds with section 15300.2(c)‘s origins in

Chickering and Friends of Mammoth. Section 15300.2(c) affirms the principle

that ―where there is any reasonable possibility that a project or activity may have a

significant effect on the environment, an exemption would be improper.‖

(Chickering, supra, 18 Cal.3d at p. 206.) And just as a project belonging to an

exempt class will have no significant effects ―in the absence of unusual

circumstances‖ (Friends of Mammoth, supra, 8 Cal.3d at p. 272), a project that

may have significant effects, despite belonging to an exempt class, is necessarily a

project that presents unusual circumstances. The only question for a court

reviewing an agency‘s section 15300.2(c) determination is whether substantial

evidence supports a fair argument that the project will have significant

environmental effects. (See Friends of “B” Street v. City of Hayward (1980) 106

Cal.App.3d 988, 1002.) It need not be more complicated than that.

Today‘s decision ventures a panoply of reasons why Chickering should not be

read to mean what it says, including the opaque contention that Chickering‘s

interpretation of section 21084(a) somehow violates ―the Legislature‘s express

directive in section 21083.1 ‗not [to] interpret‘ the CEQA statutes and the Guidelines

‗in a manner which imposes procedural or substantive requirements beyond those‘ the

13



statutes and the Guidelines ‗explicitly state[].‘ ‖ (Maj. opn., ante, at p. 24.) But the

court‘s reluctance to follow Chickering is ultimately based not on the language or

legislative history of section 21084(a), but on the premise that reading section

21084(a) and section 15300.2(c) in harmony with Chickering would deprive

categorical exemptions of any purpose or effect. Because this premise is flawed, so is

the court‘s haphazard effort to minimize Chickering‘s simple and sensible reading of

section 21084(a).

III.

It is true that over the years, the Courts of Appeal have divided on whether

―unusual circumstances‖ and ―significant effects‖ are distinct requirements in

section 15300.2(c). However, when one examines the reasoning of the many

cases applying section 15300.2(c), it is clear that ―unusual circumstances‖ and

―significant effects‖ have invariably traveled together. In the nearly four decades

since section 15300.2(c) was adopted, no published case has ever found or even

hinted that a project that belongs to an exempt category yet has a reasonable

possibility of significant environmental effects may nonetheless evade CEQA

review on the ground that the effects are not due to unusual circumstances. The

only court on record to have reached such a conclusion is the trial court in this

case. But, as today‘s opinion suggests, that conclusion is unlikely to stand. The

absence of case law finding a reasonable possibility of significant effects but no

unusual circumstances further confirms that section 15300.2(c) boils down to one

inquiry, not two.

Indeed, most courts applying section 15300.2(c) have focused directly on

whether there is a reasonable possibility that the project will have significant

environmental effects. (See, e.g., North Coast Rivers Alliance v. Westlands Water

Dist. (2014) 227 Cal.App.4th 832, 871–874 [finding no evidence of possible

14



significant environmental effects while assuming without deciding that there were

―unusual circumstances‖]; Banker’s Hill, Hillcrest, Park West Community

Preservation Group v. City of San Diego (2006) 139 Cal.App.4th 249, 278–281

[rejecting application of the exception on the ground that there were no significant

environmental effects]; San Lorenzo Valley Community Advocates for Responsible

Education v. San Lorenzo Valley Unified School Dist. (2006) 139 Cal.App.4th

1356, 1392–1394 (San Lorenzo) [no substantial evidence of significant

environmental effects]; Santa Monica Chamber of Commerce v. City of Santa

Monica (2002) 101 Cal.App.4th 786, 800–801 (Santa Monica) [only effects of

adopting a new preferred parking zone were socioeconomic, not environmental,

and therefore not cognizable under CEQA]; Apartment Assn. of Greater Los

Angeles v. City of Los Angeles (2001) 90 Cal.App.4th 1162, 1175–1176

[insufficient evidence of significant effects]; City of Pasadena v. State of

California (1993) 14 Cal.App.4th 810, 827–834 [rejecting various arguments that

a parole office located in downtown Pasadena would have significant

environmental effects]; Centinela Hospital Assn. v. City of Inglewood (1990) 225

Cal.App.3d 1586, 1601 (Centinela) [substantial evidence supported finding of no

significant environmental effect]; McQueen v. Board of Directors (1988) 202

Cal.App.3d 1136, 1149 [known existence of hazardous materials on the property

threatening the environment brings the project within the exception].)

Among cases that have focused on ―unusual circumstances,‖ it is evident

that courts have treated unusual circumstances as a proxy for significant effects.

In Wollmer v. City of Berkeley (2011) 193 Cal.App.4th 1329, 1350–1352, for

example, the court titled one part of its opinion ―No Unusual Circumstances

Preventing Categorical Exemption‖ and then proceeded to find no substantial

evidence of potential significant environmental effects. In Voices for Rural Living

v. El Dorado Irrigation Dist. (2012) 209 Cal.App.4th 1096, 1108–1113, the court

15



concluded that a casino requiring a high volume of water usage was an unusual

circumstance for a project within the ―small facilities‖ exemption, and it then

proceeded to find that such high-volume water usage presented the potential for

significant environmental risks. Other courts have employed similar reasoning.

(See Bloom v. McGurk (1994) 26 Cal.App.4th 1307, 1315–1316 [―existing

facilities‖ exemption applied to medical waste facility, and there were no ―unusual

circumstances‖ because the facility was located in an area zoned for heavy

industry and not adjacent to a residential area that might be adversely affected by

such a facility]; Azusa, supra, 52 Cal.App.4th at p. 1207 [finding landfill

―unusual‖ because it overlay a major drinking water aquifer and presented a

substantial risk of pollution].) Again, it appears that no court, other than the trial

court here, has ever found a reasonable possibility of significant effects while also

finding that the effects were not due to unusual circumstances.

As for the proper standard of review, many courts have held that the fair

argument test applies. (Maj. opn., ante, at pp. 32–33 [citing cases].) One older

case has disagreed, holding that section 15300.2(c) does not apply if there is

substantial evidence supporting the agency‘s conclusion that the project will not

generate significant effects. (Centinela, supra, 225 Cal.App.3d at p. 1601.) As

today‘s opinion notes, ―[o]ther courts have noted judicial disagreement as to

whether the fair argument standard applies in this context, but have declined to

decide the issue, finding that the standard‘s application would not have affected

the result.‖ (Maj. opn., ante, at p. 33, citing Save the Plastic Bag Coalition v. City

and County of San Francisco (2013) 222 Cal.App.4th 863, 879; Hines v.

California Coastal Commission (2010) 186 Cal.App.4th 830, 855; San Lorenzo,

supra, 139 Cal.App.4th at p. 1390; Santa Monica, supra, 101 Cal.App.4th at

p. 796; Fairbank, supra, 75 Cal.App.4th at pp. 1259–1260; Ukiah, supra, 2

Cal.App.4th at p. 728, fn. 7.) In each of these cases, the court found no substantial

16



evidence supporting a fair argument that the project would have significant

environmental effects.

Thus, courts have overwhelmingly used the fair argument standard in

reviewing the applicability of the significant effect exception either because they

believed it was the appropriate standard or because they assumed it was. For more

than two decades, courts have not felt the need to resolve the question of the

proper standard because the fair argument standard has proven adequate to the task

of ferreting out bogus CEQA challenges that would subject categorically exempt

projects to unnecessary environmental review. The ultimate touchstone of all of

these courts‘ inquiries has been whether there is a reasonable possibility that the

project would have significant environmental effects.

Today‘s opinion observes that ―evidence that the project will have a

significant effect does tend to prove that some circumstance of the project is

unusual.‖ (Maj. opn., ante, at p. 21.) This observation, though understating the

real relationship between ―significant effects‖ and ―unusual circumstances,‖

authorizes courts applying section 15300.2(c) to continue reasoning the way they

have been doing for years — i.e., focusing their inquiry on whether there is a

reasonable possibility that the project will have significant environmental effects.

Indeed, before a project has been subject to environmental review, the only thing

that courts are generally positioned to assess with confidence is whether there is a

reasonable possibility of significant environmental effects. (See No Oil, Inc. v.

City of Los Angeles (1974) 13 Cal.3d 68, 84–85.) Even under the cumbersome

rules set forth today, it is hard to imagine that any court, upon finding a reasonable

possibility of significant effects under the fair argument standard, will ever be

compelled to find no unusual circumstances and thereby uphold the applicability

of a categorical exemption. Rather, courts may continue to affirm in practice what

we have stated as a simple principle: ―where there is any reasonable

possibility that a project or activity may have a significant effect on the

environment, an exemption would be improper.‖ (Chickering, supra, 18 Cal.3d at

p. 206.)

Although I join the court in reversing and remanding for further

proceedings, I would hold that the Court of Appeal did not err in its reading of

section 15300.2(c).
