    _______________________
    In this CEQA1 action, appellants Agoura and Cornell
    Roads, LP (ACR) and Doron Gelfand (Gelfand) (collectively,
    Appellants), appeal from the trial court’s judgment granting a
    peremptory writ of mandate that directed the City of Agoura
    Hills (City) to set aside its approval of a mixed-use development
    project, and to prepare an environmental impact report (EIR) for
    the project. Appellants also appeal from the trial court’s post-
    judgment order granting attorney’s fees to the petitioners in
    the action, Save the Agoura Cornell Knoll and California Native
    Plant Society (collectively, Petitioners). Among other arguments,
    Appellants assert that the trial court erred in concluding that the
    project’s potentially significant environmental impacts required
    the preparation of an EIR rather than the mitigated negative
    declaration adopted by the City. We affirm.
    FACTUAL BACKGROUND AND PROCEDURAL HISTORY
    I.    The Proposed Project
    This action challenges the City’s approval of a mixed-use
    commercial and residential development proposed by Appellants.
    The project, known as the Cornerstone Mixed-Use Project,
    proposed the development of 35 residential apartment units plus
    retail, restaurant, and office space on an 8.2-acre site. The
    project site is on an undeveloped hillside at the southeast corner
    of Agoura Road and Cornell Road in Agoura Hills, California.
    1     CEQA refers to the California Environmental Quality
    Act (Pub. Resources Code, § 21000 et seq.) and the regulations
    implementing it (Cal. Code Regs., tit. 14, § 15000 et seq.) (CEQA
    Guidelines). Unless otherwise stated, all further statutory
    references are to the Public Resources Code.
    2
    The property is mostly covered with grasses and scattered oak
    trees, and its dominant feature is a knoll with oak trees at the
    corner of Agoura Road and Cornell Road. In addition to oak trees
    and scrub oak habitat, the site contains both native and non-
    native plants, including three plant species that are considered to
    be rare, threatened, or endangered. Although the site is vacant
    with no existing structures, commercial retail centers are located
    to the west, northwest, and north of the property.
    The majority of the project site is located in an area covered
    by the Agoura Village Specific Plan (AVSP). The portion of
    the site that is outside the AVSP-covered area is located in a
    Significant Ecological Area. The AVSP sets forth regulations and
    guidelines for new developments in the planning area. The City
    certified a final EIR for the AVSP in 2006, and adopted the AVSP
    in 2008. As proposed, the Cornerstone Mixed-Use Project would
    consolidate 24 parcels into two lots, with approximately 6.23
    acres in Lot 1 and 1.98 acres in Lot 2. The area in Lot 2 would be
    reserved for open space in accordance with the AVSP.
    II.   Administrative Proceedings
    ACR is a California limited partnership and the owner of
    the property located at the project site. Gelfand is a limited
    partner of ACR. Gelfand submitted applications to the City for
    a development permit, a conditional use permit, an oak tree
    permit, and a tentative parcel map for the Cornerstone Mixed-
    Use Project. After reviewing various studies and reports to
    evaluate the potential environmental impacts, the City issued a
    final Initial Study-Mitigated Negative Declaration (MND) for the
    project in November 2016. At a public hearing held on January
    5, 2017, the Agoura Hills Planning Commission voted to approve
    3
    the project and adopt the MND.
    The Los Angeles/Santa Monica Mountains chapter of the
    California Native Plant Society (CNPS), a statewide non-profit
    organization focused on the preservation of native California
    plants, appealed the Planning Commission’s decision. On March
    8, 2017, the Agoura Hills City Council held a public hearing on
    the appeal. At the close of the hearing, the City Council approved
    the Cornerstone Mixed-Use Project and adopted the MND. The
    City Council found that, based on the record before it, there was
    no substantial evidence that the project would have a significant
    effect on the environment because the project plans incorporated
    feasible mitigation measures that would reduce any potential
    environmental impacts to a less than significant level. On March
    16, 2017, the City filed a Notice of Determination of its approval
    of the project and adoption of the MND.
    III.   Writ Proceedings
    Save the Agoura Cornell Knoll (STACK), a local citizen’s
    group, filed a verified petition for writ of mandate on April 7,
    2017, and a first amended petition on August 10, 2017. The first
    amended petition added CNPS as a petitioner. It named the
    City, the Agoura Hills City Council, and the Agoura Hills
    Planning Commission as respondents, and ACR and Gelfand as
    real parties in interest. The petition alleged three causes of
    action for violation of CEQA, violation of planning and zoning
    law, and violation of the City’s Oak Tree Ordinance. On January
    29, 2018, Appellants and the City each filed an opposition to the
    petition. On February 13, 2018, Petitioners filed a reply.
    The trial court held a hearing on the writ petition on March
    13, and May 22, 2018. On May 23, 2018, the court issued a 64-
    4
    page decision granting in part and denying in part the petition.
    The court granted the petition as to the causes of action for
    violation of CEQA and violation of the City’s Oak Tree
    Ordinance, and denied the petition as to the cause of action for
    violation of planning and zoning law. With respect to the CEQA
    claim, the court concluded that there was substantial evidence to
    support a fair argument that the project may have significant
    environmental impacts on cultural resources, sensitive plant
    species, oak trees, and aesthetic resources, and that the MND’s
    proposed mitigation measures are inadequate to reduce those
    impacts to less than significant. With respect to the Oak Tree
    Ordinance claim, the court concluded that the permit issued by
    the City violated the ordinance’s prohibition against the removal
    of more than 10 percent of the total estimated oak tree canopy or
    root structure on the project site.
    On June 26, 2018, the trial court entered judgment in favor
    of Petitioners on their causes of action for violation of CEQA and
    violation of the Oak Tree Ordinance, and ordered the issuance
    of a peremptory writ of mandate. On July 20, 2018, the court
    issued the writ of mandate directing the City to set aside its
    approval of permits for the project. The writ also directed the
    City to set aside the MND that it had adopted for the project and
    to prepare an EIR in compliance with the court’s May 23, 2018
    decision. On August 23, 2018, Appellants filed an appeal from
    the judgment (Appeal B292246).
    IV.   Post-Judgment Attorney’s Fees
    On August 24, 2018, Petitioners filed a motion to recover
    their attorney’s fees pursuant to Code of Civil Procedure section
    1021.5. Petitioners sought a total of $339,559 in attorney’s fees,
    5
    which included a request for a lodestar multiplier of 2.0. On
    November 1, 2018, Appellants and the City each filed an
    opposition. The City opposed only the requested multiplier.
    Appellants contested Petitioners’ entitlement to attorney’s fees,
    the amount of fees sought, and Gelfand’s individual liability for a
    fee award.
    On November 15, 2018, the trial court partially granted the
    motion and found that Petitioners were entitled to attorney’s fees
    in the amount of $142,148. The court denied Petitioners’ request
    for a lodestar multiplier, and ordered supplemental briefing on
    whether Gelfand was individually liable for the fee award. On
    December 18, 2019, after considering the parties’ supplemental
    briefs, the trial court found that Gelfand and ACR were jointly
    and severally liable for the attorney’s fees. The court awarded
    Petitioners a total of $142,148 in attorney’s fees with 50 percent
    payable by the City and 50 percent payable by ACR and Gelfand.
    On January 9, 2019, Appellants filed an appeal from the post-
    judgment order for attorney’s fees (Appeal B295112).2
    2     On February 22, 2019, this court denied Appellants’ motion
    to consolidate Appeals B292246 and B295112, but ordered that
    the appeals be considered concurrently for the purposes of oral
    argument and decision.
    6
    DISCUSSION
    In Appeal No. B292246, Appellants challenge the trial
    court’s issuance of a writ of mandate directing the City to set
    aside its approval of the Cornerstone Mixed-Use Project and to
    prepare an EIR for the project. In Appeal No. B295112, they
    contest the trial court’s post-judgment award of attorney’s fees
    to Petitioners as the successful parties in the CEQA action.
    I.    Overview Of CEQA
    CEQA and the regulations implementing it “embody
    California’s strong public policy of protecting the environment.”
    (Tomlinson v. County of Alameda (2012) 
    54 Cal. 4th 281
    , 285.) As
    the California Supreme Court has explained, “CEQA was enacted
    to advance four related purposes: to (1) inform the government
    and public about a proposed activity's potential environmental
    impacts; (2) identify ways to reduce, or avoid, environmental
    damage; (3) prevent environmental damage by requiring project
    changes via alternatives or mitigation measures when feasible;
    and (4) disclose to the public the rationale for governmental
    approval of a project that may significantly impact the
    environment.” (California Building Industry Assn. v. Bay Area
    Air Quality Management Dist. (2015) 
    62 Cal. 4th 369
    , 382.)
    “CEQA review is undertaken by a lead agency, defined as
    ‘the public agency which has the principal responsibility for
    carrying out or approving a project which may have a significant
    effect upon the environment.’ [Citation.]” (Friends of the Eel
    River v. North Coast Railroad Authority (2017) 
    3 Cal. 5th 677
    ,
    712, italics omitted.) The lead agency’s implementation of CEQA
    “proceeds by way of a multistep decision tree, which has been
    7
    characterized as having three tiers. [Citation.] First, the agency
    must determine whether the proposed activity is subject to CEQA
    at all. Second, assuming CEQA is found to apply, the agency
    must decide whether the activity qualifies for one of the many
    exemptions that excuse otherwise covered activities from CEQA’s
    environmental review. Finally, assuming no applicable
    exemption, the agency must undertake environmental review of
    the activity. . . .” (Union of Medical Marijuana Patients, Inc. v.
    City of San Diego (2019) 
    7 Cal. 5th 1171
    , 1185, fn. omitted.)
    When a proposed activity is a project and does not qualify
    for a CEQA exemption, “the agency must first undertake an
    initial study to determine whether the project ‘may have a
    significant effect on the environment.’ [Citations.] If the initial
    study finds no substantial evidence that the project may have a
    significant environmental effect, the lead agency must prepare
    a negative declaration, and environmental review ends.
    [Citations.] If the initial study identifies potentially significant
    environmental effects but (1) those effects can be fully mitigated
    by changes in the project and (2) the project applicant agrees to
    incorporate those changes, the agency must prepare a mitigated
    negative declaration. This too ends CEQA review. [Citations.]
    Finally, if the initial study finds substantial evidence that the
    project may have a significant environmental impact and a
    mitigated negative declaration is inappropriate, the lead agency
    must prepare and certify an EIR before approving or proceeding
    with the project. [Citations.]” (Union of Medical Marijuana
    Patients, Inc. v. City of San 
    Diego, supra
    , 
    7 Cal. 5th 1171
    at
    pp. 1186-1187; see also § 21080, subds. (c), (d).)
    “At the ‘heart of CEQA’ [citation] is the requirement that
    public agencies prepare an EIR for any ‘project’ that ‘may have a
    8
    significant effect on the environment.’ [Citations.]” (Friends of
    College of San Mateo Gardens v. San Mateo County Community
    College Dist. (2016) 
    1 Cal. 5th 937
    , 944.) “Given the statute’s
    text, and its purpose of informing the public about potential
    environmental consequences, it is quite clear that an EIR is
    required even if the project’s ultimate effect on the environment
    is far from certain. [Citations.]” (California Building Industry
    Assn. v. Bay Area Air Quality Management 
    Dist., supra
    , 62
    Cal.4th at pp. 382-383, italics omitted.) Accordingly, “‘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.’” (Berkeley Hillside Preservation v. City of Berkeley (2015)
    
    60 Cal. 4th 1086
    , 1111-1112, quoting CEQA Guidelines, § 15064,
    subd. (f)(1); see also Save the Plastic Bag Coalition v. City of
    Manhattan Beach (2011) 
    52 Cal. 4th 155
    , 171 [“If the agency’s
    initial study of a project produces substantial evidence
    supporting a fair argument the project may have significant
    adverse effects, the agency must . . . prepare an EIR.”].)3
    “In reviewing an agency’s . . . decision for compliance with
    CEQA, we ask whether the agency has prejudicially abused its
    discretion; such an abuse is established ‘if the agency has not
    proceeded in a manner required by law or if the determination or
    3     For CEQA purposes, a significant effect on the environment
    means “a substantial, or potentially substantial, adverse change
    in any of the physical conditions within the area affected by the
    project including land, air, water, minerals, flora, fauna, ambient
    noise, and objects of historic or aesthetic significance.” (CEQA
    Guidelines, § 15382; see also §§ 21060.5, 21151, subd. (b).)
    9
    decision is not supported by substantial evidence.’ ([ ] § 21168.5.)
    In determining whether there has been an abuse of discretion,
    we review the agency’s action, not the trial court’s decision. ‘[I]n
    that sense appellate judicial review under CEQA is de novo.’
    [Citation.]” (Center for Biological Diversity v. Department of Fish
    & Wildlife (2015) 
    62 Cal. 4th 204
    , 214-215.) We determine de
    novo whether the agency has employed the proper procedures,
    and we review the agency’s substantive factual conclusions for
    substantial evidence. (Sierra Club v. County of Fresno (2018) 
    6 Cal. 5th 502
    , 512; Covina Residents for Responsible Development
    v. City of Covina, (2018) 
    21 Cal. App. 5th 712
    , 724.)
    An agency’s decision to rely on a negative declaration or a
    mitigated negative declaration under CEQA “‘is reviewed for
    abuse of discretion under the “fair argument” standard.’” (Jensen
    v. City of Santa Rosa (2018) 
    23 Cal. App. 5th 877
    , 886; see also
    Wollmer v. City of Berkeley (2009) 
    179 Cal. App. 4th 933
    , 939.) In
    describing the scope of judicial review of an agency’s application
    of the fair argument standard, the Supreme Court has stated:
    “[A] reviewing court may not uphold an agency’s decision [not to
    prepare an initial EIR under the fair argument test] ‘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
    10
    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.”’” (Berkeley Hillside Preservation v. City of 
    Berkeley, supra
    ,
    60 Cal.4th at p. 1112.) “The fair argument standard thus creates
    a low threshold for requiring an EIR, reflecting the legislative
    preference for resolving doubts in favor of environmental review.
    [Citation.]” (Covina Residents for Responsible Development v.
    City of 
    Covina, supra
    , 21 Cal.App.5th at p. 723, fn. omitted.)
    II.   Exhaustion Of Administrative Remedies
    As a preliminary matter, we first consider Appellants’
    argument that Petitioners waived any claim that they exhausted
    administrative remedies by failing to raise the issue in their
    opening brief before the trial court and instead addressing it for
    the first time in their reply brief. Appellants further assert that,
    given the purported waiver, the trial court erred in considering
    the evidence cited by Petitioners in their reply brief to show they
    had satisfied the exhaustion requirement.4
    4      Although Appellants refer to the alleged failure to
    preserve the issue of exhaustion as a waiver, the proper term
    is forfeiture. As the Supreme Court has explained in various
    contexts: “‘“[W]aiver” means the intentional relinquishment or
    abandonment of a known right.’ [Citations.] … [¶] … [Waiver]
    differs from the related concept of forfeiture, which results when
    a party fails to preserve a claim by raising a timely objection.
    [Citation.]” (Lynch v. California Coastal Com. (2017) 
    3 Cal. 5th 470
    , 475-476.) Therefore, “‘forfeiture results from the failure to
    11
    A.    CEQA’s Exhaustion Requirement
    “The rule requiring exhaustion of administrative remedies
    is well settled. ‘In general, a party must exhaust administrative
    remedies before resorting to the courts. [Citations.] Under
    this rule, an administrative remedy is exhausted only upon
    “termination of all available, nonduplicative administrative
    review procedures.” [Citations.]’” (Williams & Fickett v. County
    of Fresno (2017) 
    2 Cal. 5th 1258
    , 1267-1268.) “‘The rule “is not
    a matter of judicial discretion, but is a fundamental rule of
    procedure . . . binding upon all courts.”’ [Citation.]” (Plantier v.
    Ramona Municipal Water Dist. (2019) 
    7 Cal. 5th 372
    , 383.)
    “‘“Exhaustion of administrative remedies is a jurisdictional
    prerequisite to maintenance of a CEQA action.”’” (City of Long
    Beach v. City of Los Angeles (2018) 
    19 Cal. App. 5th 465
    , 474.)
    Section 21177 sets forth CEQA’s exhaustion requirement. It
    provides, in relevant part, that a CEQA action “shall not be
    brought . . . unless the alleged grounds for noncompliance . . .
    were presented to the public agency orally or in writing by any
    person during the public comment period . . . or prior to the close
    of the public hearing on the project before the issuance of the
    notice of determination.” (§ 21177, subd. (a).) “The purpose of
    the exhaustion doctrine is to ensure public agencies are given the
    opportunity to decide matters within their expertise, respond to
    objections, and correct any errors before the courts intervene.
    [Citations.]” (Bridges v. Mt. San Jacinto Community College
    Dist. (2017) 
    14 Cal. App. 5th 104
    , 115; see also Sierra Club v. City
    invoke a right, while waiver denotes an express relinquishment
    of a known right; the two are not the same.’” (Id. at p. 476.)
    12
    of Orange (2008) 
    163 Cal. App. 4th 523
    , 535 [“‘The rationale for
    exhaustion is that the agency “‘is entitled to learn the contentions
    of interested parties before litigation is instituted. If [plaintiffs]
    have previously sought administrative relief . . . the [agency] will
    have had its opportunity to act and to render litigation
    unnecessary, if it had chosen to do so.’”’”].)
    “‘To advance the exhaustion doctrine’s purpose[,] “[t]he
    ‘exact issue’ must have been presented to the administrative
    agency. . . .” [Citation.] While “‘less specificity is required to
    preserve an issue for appeal in an administrative proceeding
    than in a judicial proceeding’” . . . “generalized environmental
    comments at public hearings,” “relatively . . . bland and general
    references to environmental matters” [citation], or “isolated and
    unelaborated comment[s]” [citation] will not suffice. The same is
    true for “‘[g]eneral objections to project approval. . . .’ [Citations.]”
    [Citation.] “‘[T]he objections must be sufficiently specific so that
    the agency has the opportunity to evaluate and respond to
    them.’”’ [Citation.]” (City of Long Beach v. City of Los 
    Angeles, supra
    , 19 Cal.App.5th at pp. 474-475.) “‘“The petitioner bears the
    burden of demonstrating that the issues raised in the judicial
    proceeding were first raised at the administrative level.
    [Citation.]” [Citation.] An appellate court employs a de novo
    standard of review when determining whether the exhaustion of
    administrative remedies doctrine applies. [Citation.]’ [Citation.]”
    (Monterey Coastkeeper v. State Water Resources (2018) 
    28 Cal. App. 5th 342
    , 359; see also Bridges v. Mt. San Jacinto
    Community College 
    Dist., supra
    , 14 Cal.App.5th at pp. 116-117.)
    13
    B.    Petitioners Did Not Forfeit Their Claim That
    They Exhausted Administrative Remedies
    The record reflects that, in the first amended petition for
    writ of mandate filed in the trial court, Petitioners specifically
    alleged that they had “performed all conditions precedent to filing
    this action, including exhaustion of all administrative remedies
    available to them.” They did not address the issue of exhaustion
    in their opening brief to the trial court. However, in arguing that
    the MND failed to mitigate the project’s significant impacts,
    Petitioners did cite some of the public comments made in the
    administrative proceedings, which described those impacts and
    disputed the adequacy of the MND’s mitigation measures. After
    Appellants and the City argued in their opposition briefs that
    Petitioners had failed to prove exhaustion as to each of their
    claims, Petitioners then responded to this argument in their
    reply brief by asserting that they had exhausted administrative
    remedies as to the specific issues raised in their petition, and by
    citing the portions of the administrative record that they claimed
    showed this requirement had been met.
    At both the March 13, 2018 and May 22, 2018 hearings on
    the writ petition, the trial court heard argument as to whether
    Petitioners had forfeited their right to establish the exhaustion
    of administrative remedies by failing to raise the issue in their
    opening brief, and if not, whether exhaustion was shown as to
    specific claims alleged in the petition. At the end of the March
    13, 2018 hearing, the trial court denied Appellants’ request to
    allow supplemental briefing on the arguments made at that
    hearing. Despite this denial, Appellants filed a supplemental
    brief on May 14, 2018, in which they asserted that any alleged
    evidence of exhaustion should not be admitted. In its May 23,
    14
    2018 decision, the trial court granted Petitioners’ request to
    strike Appellants’ supplemental brief for disregarding its prior
    order, and found that Petitioners had not forfeited the issue of
    exhaustion by addressing it for the first time in their reply brief.
    The court also found that CEQA’s exhaustion requirement was
    satisfied as to some, but not all, of the issues raised in the
    petition.
    Appellants contend that the trial court erred in considering
    any alleged evidence of exhaustion included in the administrative
    record because Petitioners forfeited the issue by failing to raise it
    in their opening brief in the writ proceedings. We conclude that
    this claim lacks merit. While Petitioners bore the burden of
    proving the exhaustion of administrative remedies, there was
    no jurisdictional requirement that they argue the issue in a
    separate section of their opening brief. Some of the evidence that
    Petitioners cited in their opening brief to support the merits of
    their CEQA claims was the same evidence that they cited in their
    reply to show they had exhausted administrative remedies.
    Petitioners adequately preserved the issue for consideration in
    the trial court by expressly alleging in their petition that they
    had exhausted all administrative remedies; by lodging the
    complete administrative record with the court as part of the writ
    proceedings; by citing the relevant portions of the administrative
    record that supported their claims in their opening brief; and by
    citing the evidence of exhaustion in their reply brief in response
    to Appellants’ contention that exhaustion had not been shown.
    As explained in Save Our Residential Environment v. City
    of West Hollywood (1992) 
    9 Cal. App. 4th 1745
    , a case cited by
    the trial court in rejecting Appellants’ forfeiture claim, “[t]he
    purposes of CEQA, including the provisions regarding the
    15
    exhaustion of administrative remedies, are not served by
    requiring proof in the record of compliance with the requirement
    that a person objecting to the [p]roject present his or her
    comments, orally or in writing, at the appropriate stage of the
    proceedings when there is no real dispute that the requirement
    was in fact met.” (Id. at p. 1750.) Here, once Appellants placed
    the issue of exhaustion in dispute by asserting in their opposition
    that this requirement had not been met, Petitioners addressed
    the issue in their reply based on the evidentiary record before the
    trial court. The court then gave the parties ample opportunity
    over the course of two hearings to argue whether Petitioners had
    in fact exhausted administrative remedies as to each issue raised
    in the petition. Under these circumstances, Petitioners’ failure to
    argue in their opening brief that they satisfied the exhaustion
    requirement as to each of their claims did not result in the
    forfeiture of that issue in the trial court.
    None of the cases cited by Appellants in support of
    forfeiture compel a different conclusion. In two of the cases–St.
    Mary v. Superior Court (2014) 
    223 Cal. App. 4th 762
    and Balboa
    Ins. Co. v. Aguirre (1983) 
    149 Cal. App. 3d 1002
    –the appellate
    court applied the well-established principle that new legal
    theories raised for the first time in a reply brief generally will
    not be considered unless good cause is shown for the failure to
    present them earlier. (St. Mary v. Superior 
    Court, supra
    , at
    pp. 782-783 [defendants raised new theory for relief in reply brief
    filed in support of discovery motion despite representations to
    trial court that motion was not based on that ground]; Balboa
    Ins. Co. v. 
    Aguirre, supra
    , at pp. 1009-1010 [plaintiff forfeited
    equal protection claim where issue was never raised in trial court
    and was asserted for first time in reply brief on appeal].) This
    16
    principle does not, however, preclude Petitioners from proving
    exhaustion of administrative remedies because that issue was
    not a new legal theory raised for the first time in a reply brief.
    Rather, as discussed, it was first alleged by Petitioners in their
    writ petition and then argued in their reply in direct response to
    the failure-to-exhaust arguments raised by Appellants and the
    City. The other cases on which Appellants rely–Jay v. Mahaffey
    (2013) 
    218 Cal. App. 4th 1522
    and Plenger v. Alza Corp. (1992) 
    11 Cal. App. 4th 349
    – are also inapposite. In each of those cases, the
    moving party offered new evidence with their reply papers. (Jay
    v. 
    Mahaffey, supra
    , at p. 1538 [moving parties in anti-SLAPP
    motion “wait[ed] until the reply briefs to bring forth any evidence
    at all, when the [opposing parties] would have no opportunity to
    respond”]; Plenger v. Alza 
    Corp., supra
    , at p. 362, fn. 8 [where
    party moving for summary judgment offered new evidence with
    reply, trial court had discretion to consider such additional
    evidence “so long as the [opposing] party . . . ha[d] notice and an
    opportunity to respond”].) Here, Petitioners did not submit any
    new evidence of exhaustion with their reply brief, but rather cited
    the evidence in the already-admitted administrative record.
    Appellants also have failed to show that they suffered any
    prejudice from the trial court’s consideration of the evidence of
    exhaustion cited in Petitioners’ reply. Appellants assert that the
    trial court’s decision to allow such evidence while rejecting their
    supplemental brief deprived them of an opportunity to respond to
    Petitioners’ claim that they satisfied the exhaustion requirement.
    The trial court, however, acted well within its discretion in
    striking Appellants’ supplemental brief, which was filed in direct
    contravention of the court’s order at the March 13, 2018 hearing
    where the issue of exhaustion was thoroughly argued. (Bozzi v.
    17
    Nordstrom, Inc. (2010) 
    186 Cal. App. 4th 755
    , 765 [trial court had
    broad discretion to refuse to consider a “surrebuttal brief” filed
    without a prior court order finding good cause for the late
    submission].) Moreover, as Petitioners correctly note, this court
    independently reviews the administrative record to determine
    whether the exhaustion of administrative remedies doctrine
    applies. Given that the parties have had an opportunity to fully
    brief the issue of exhaustion in the appeal before this court,
    Appellants cannot show they were prejudiced by Petitioners’
    failure to argue the issue in their opening brief before the trial
    court. On this record, the issue of whether Petitioners exhausted
    their administrative remedies has not been forfeited.5
    III.   Standing And Statute of Limitations
    Notwithstanding their arguments concerning forfeiture, in
    their own appellate reply brief, Appellants assert for the first
    time that this entire action must be dismissed because STACK
    lacks standing to bring the action under CEQA, and CNPS is
    barred by the statute of limitations from serving as a substitute
    petitioner. With respect to standing, Appellants specifically
    5      In addition to forfeiture, Appellants contend that
    Petitioners failed to meet their burden of proving that they
    exhausted administrative remedies as to the specific claims
    raised in their writ petition. We consider whether CEQA’s
    exhaustion requirement was satisfied as to Petitioners’ claims
    about the project’s impacts on cultural resources, sensitive plant
    species, oak trees, and aesthetic resources in our discussion of
    each of these alleged environmental impacts. We also consider
    whether Petitioners exhausted administrative remedies as to
    their cause of action for violation of the City’s Oak Tree
    Ordinance in our discussion of that claim.
    18
    argue that STACK failed to prove that either the organization or
    any of its members objected to the approval of the project prior to
    the close of the public hearing, as required by section 21177.6
    With respect to the statute of limitations, Appellants claim that
    CNPS cannot maintain the action because it was not named as
    a petitioner until the first amended petition, which was filed
    after the statute of limitations in section 21167 had expired.7
    Appellants contend that, in the absence of a proper petitioner,
    this court lacks jurisdiction to hear any of the CEQA claims.
    Appellants never asserted the lack of standing or the
    statute of limitations in the proceedings before the trial court,
    nor did they argue these issues in their opening brief on appeal.
    In raising these issues for the first time in their reply brief,
    Appellants do not offer any explanation for their failure to
    present them earlier. Rather, they simply cite the general rule
    that “a contention based on a plaintiff’s lack of standing cannot
    be waived . . . and may be raised at any time in the proceeding.”
    6      Section 21177, subdivision (b) states that “[a] person shall
    not maintain an action or proceeding unless that person objected
    to the approval of the project orally or in writing during the
    public comment period provided by this division or before the
    close of the public hearing on the project before the filing of notice
    of determination. . . .” Subdivision (c) of the statute provides that
    “[t]his section does not preclude any organization formed after
    the approval of a project from maintaining an action . . . if a
    member of that organization has complied with subdivision (b).”
    7     Section 21167, subdivision (b) provides that “[a]n action
    or proceeding alleging that a public agency has improperly
    determined whether a project may have a significant effect on
    the environment shall be commenced within 30 days from the
    date of the filing of the notice [of determination].”
    19
    (McKinny v. Board of Trustees (1982) 
    31 Cal. 3d 79
    , 90.) While
    it is true that the issue of standing can be raised at any time,
    including for the first time on appeal, that is not the case with
    the statute of limitations. “Because a statute of limitations is an
    affirmative defense, it is forfeited if it is not properly asserted in
    a general demurrer or pleaded in an answer. [Citations.]” (PGA
    West Residential Assn., Inc. v. Hulven Internat., Inc. (2017) 
    14 Cal. App. 5th 156
    , 176; accord, Minton v. Cavaney (1961) 
    56 Cal. 2d 576
    , 581.) Here, neither Appellants nor the City pleaded the
    statute of limitations in their respective answers to the first
    amended petition, nor did they assert it in a demurrer to the
    petition. The defense was thus forfeited. Additionally, by failing
    without explanation to present any argument regarding the
    statute of limitations in their opening brief, Appellants are
    precluded from raising it in their reply. (California Building
    Industry Assn. v. State Water Resources (2018) 
    4 Cal. 5th 1032
    ,
    1050 [where appellant fails to raise an argument “until its
    appellate reply brief,” it “has forfeited the argument”];
    Varjabedian v. City of Madera (1977) 
    20 Cal. 3d 285
    , 295, fn. 11
    [“[o]bvious reasons of fairness militate against consideration of
    an issue raised initially in the reply brief of an appellant”].)
    Under these circumstances, we need not consider whether
    STACK has standing to bring this action under CEQA.8 Even if
    8     Resolving the issue of STACK’s standing in this case also
    would fall outside the proper scope of appellate review because it
    would require consideration of factual issues not included in the
    record, such as when STACK was formed and whether any of
    its members objected to the approval of the project during the
    administrative proceedings. (Tanguilig v. Neiman Marcus
    Group, Inc. (2018) 
    22 Cal. App. 5th 313
    , 330 [“appellant may not
    raise a new theory on appeal when the theory rests on facts that
    20
    we were to assume that STACK lacks standing, Appellants do
    not dispute that CNPS has standing, and they have forfeited
    any claim that CNPS cannot maintain the action based on the
    statute of limitations. Because at least one of the petitioners has
    standing under CEQA, this court has jurisdiction over the appeal.
    IV.   Impacts On Cultural Resources
    In granting the writ petition on the cause of action for
    violation of CEQA, the trial court concluded that an EIR was
    required to consider the project’s impacts on tribal cultural
    resources. Appellants argue that the trial court erred in
    reaching this conclusion because Petitioners failed to exhaust
    administrative remedies as to their cultural resource claims.
    Appellants further assert that, even if exhaustion was shown,
    there was no substantial evidence to support a fair argument
    that the MND’s mitigation measures are insufficient to reduce
    the impacts on cultural resources to less than significant.
    A.     Relevant Background
    Prior to the arrival of the Europeans, a Native American
    group known as the Chumash occupied the region where the
    project site is located. The project site includes an identified
    prehistoric archaeological site, CA-LAN-1352, which consists of a
    surface scatter of lithic artifacts and a subsurface deposit at the
    were . . . not fully developed in the trial court”]); Rayii v. Gatica
    (2013) 
    218 Cal. App. 4th 1402
    , 1409 [appellate court “will not
    consider a new issue where the failure to raise the issue in the
    trial court deprived an opposing party of the opportunity to
    present relevant evidence”].)
    21
    northern end of the property. Studies of CA-LAN-1352 conducted
    in 1988 and 2004 determined the site represented a significant
    heritage resource under CEQA. In 2011, an expanded Phase II
    test excavation of the site concluded that it met the requirements
    for inclusion in the California Register of Historical Resources
    (CRHR) because it retained the potential to yield information
    important to the prehistory of the area. In 2014, Rincon
    Consultants, Inc. prepared a peer review of the 2011 study and
    concurred with that study’s assessment that the site was eligible
    for listing in the CRHR. The 2014 peer review recommended
    that CA-LAN-1352 should be avoided, and if avoidance was not
    feasible, then a Phase III data recovery program should be
    conducted. It also recommended that all construction-related
    ground-disturbing activities should be monitored by a qualified
    archaeologist and a Chumash Native American representative.
    In adopting the MND, the City reviewed the archaeological
    studies of CA-LAN-1352 conducted in 1988, 2004, and 2011, and
    the peer review report prepared in 2014. The City concluded
    that, because the project would involve extensive grading of the
    site to develop multiple mixed-use buildings and parking areas,
    the environmental impacts on cultural resources were potentially
    significant and would require mitigation. The MND sets forth
    three mitigation measures–CS-CR-1, CS-CR-2, and CS-CR-3–
    that the City contended would reduce the project’s impacts on
    cultural resources to a less than significant level.
    CS-CR-1 requires monitoring of the site during ground-
    disturbing activities. It provides, in relevant part: “Monitoring
    of all project related ground disturbing activities of sediments
    that appear to be in a primary context shall be conducted by
    a qualified archaeologist and/or paleontologist [and Native
    22
    American monitor qualified to identify Chumash and Gabrieleno
    resources] approved by the City Planning Department. . . . If
    archaeological/paleontological resources are encountered during
    ground-disturbing activities, the City Planning Department shall
    be notified immediately, and work shall stop within a 100-foot
    radius until the archeologist has assessed the nature, extent, and
    potential significance of any remains pursuant to [CEQA]. In
    the event such resources are determined to be significant,
    appropriate actions are to be determined by the archeologist
    consistent with CEQA . . . and the City General Plan, in
    consultation with the City Planning Department.”
    CS-CR-2 addresses the proper notification process if any
    human remains are discovered at the site. It states, in pertinent
    part, that in the event human remains are discovered, “the City’s
    Environmental Analyst and County Coroner shall be notified
    immediately. . . . If the human remains are determined to be
    prehistoric, the County Coroner shall notify the Native American
    Heritage Commission, which will determine and then notify the
    Most Likely Descendent (MLD). The MLD shall complete an
    inspection and make a recommendation within 48 hours of the
    notification. If no recommendation is received, the remains shall
    be interred with appropriate dignity on the property in a location
    not subject to future development.”
    CS-CR-3 mandates an excavation program if the site
    cannot be avoided. It provides: “If avoidance of CA-LAN-1352 is
    not possible, the project applicant shall complete a Phase III data
    recovery excavation program prior to project-related ground
    disturbance. The Phase III data recovery program should be
    completed by a professional archeologist who meets the Secretary
    of the Interior’s Professional Qualifications Standards for
    23
    prehistoric archaeology . . . and include the preparation of a work
    plan/research design, fieldwork, laboratory analysis of recovered
    artifacts and ecofacts, special studies if appropriate, the
    preparation of a technical report, and curation of recovered
    materials. The technical report shall include a mitigation
    monitoring and reporting plan. The Phase III fieldwork shall be
    conducted by a Native American monitor qualified to identify
    Chumash and Gabrieleno resources.”
    B.    Petitioners Exhausted Administrative
    Remedies As To The Cultural Resource Claims
    In the writ proceedings, Petitioners raised six arguments
    regarding the project’s potential impacts on cultural resources.
    The trial court found Petitioners had exhausted administrative
    remedies as to four of the six arguments. On appeal, Appellants
    assert that none of these claims were raised in the administrative
    proceedings. Based on our independent review of the record, we
    conclude that Petitioners satisfied the exhaustion requirement
    as to each cultural resource claim at issue in this appeal.
    Petitioners’ first claim is that the MND fails to identify and
    analyze CA-LAN-1352 as a tribal cultural resource in accordance
    with sections 21074, subdivision (a) and 21082.3, subdivision (b).
    Section 21074 defines “tribal cultural resources” as including
    sites with cultural value to a California Native American tribe
    that are determined to be eligible for inclusion in the CRHR.
    (§ 21074, subd. (a)(1).) Section 21082.3 provides that, if a project
    may have a significant impact on an identified tribal cultural
    resource, the environmental document shall discuss the impact
    and any feasible alternatives or mitigation measures, including
    measures that may be agreed upon in consultation with a
    24
    California Native American tribe that is affiliated with the
    geographic area of the project. (§ 21082.3, subd. (b).) While it
    appears that none of the public comments submitted to the City
    cited these specific statutory provisions, several objections were
    raised about the City’s failure to consult with Chumash tribes on
    measures that could preserve the site’s cultural resources.
    Specifically, in a February 2016 letter to the City Council,
    archeologist Chester King stated: “I found no evidence of
    consultation with Native American tribes as required by . . .
    section 21083.099 in the MN[D]. The significance of the loss of
    the cultural resource to Chumash people and the possibility of
    mitigation of the loss needs to be determined as part of the
    environmental review.” The letter also noted that “[n]o project
    alternatives are presented that result in preservation of the site.”
    Similarly, in a February 2017 email to the City’s Planning
    Director, a member of the Elders Council of the Santa Ynez Band
    of Chumash Indians wrote: “The area in which this project is
    being proposed is considered to be sensitive when it comes to
    Chumash culture. . . . What measures, in consultation with
    Chumash tribes, has the City of Agoura Hills Planning Dept. and
    the applicant made to assure and avoid impacts to cultural
    heritage?” At the March 2017 City Council hearing, an
    individual named Emily Hilfand also complained about the lack
    of consultation with Chumash tribes, stating: “I’m very
    concerned about the known impacts [to] . . . CALAN1352. The
    City never contacted any Chumash tribe members about this
    9     Section 21083.09 required the Office of Planning and
    Research to revise the CEQA guidelines to include separate
    consideration of tribal cultural resources.
    25
    plan.” Taken together, these comments fairly apprised the City
    of the concern that the MND failed to adequately address project
    alternatives or mitigation measures that could preserve tribal
    cultural resources, including measures formed in consultation
    with the Chumash tribes. (See Santa Clarita Organization for
    Planning the Environment v. City of Santa Clarita (2011) 
    197 Cal. App. 4th 1042
    , 1052 [“[d]espite the general nature” of an
    advocacy group’s letter, it “‘fairly apprised’ the city of [the
    group’s] concerns” about the proposed mitigation measure];
    California Native Plant Society v. County of El Dorado (2009) 
    170 Cal. App. 4th 1026
    , 1056 [where CNPS argued in public comments
    that the proposed mitigation was not adequate, it “‘fairly
    apprised the [c]ounty’ of its central claims”].)
    Petitioners’ three remaining claims concern CS-CR-3.10
    In the writ proceedings, Petitioners challenged this mitigation
    measure on the following grounds: (1) it improperly defers
    analysis of the project’s impacts on cultural resources by failing
    to define the boundaries of CA-LAN-1352 and to determine the
    feasibility of avoidance; (2) it is insufficient to mitigate the
    impacts on cultural resources to a level below significant; and
    (3) it improperly defers formulation of a Phase III data recovery
    program, including a mitigation plan. The record reflects that
    these claims were adequately presented to the City.
    Among the objections set forth in his February 2016 letter,
    Dr. King stated that the “project will destroy” CA-LAN-1352, that
    “avoidance is not feasible without changing the project footprint,”
    10    Petitioners did not raise any claims regarding CS-CR-2 or
    the adequacy of the MND in addressing any potential discovery
    of human remains at the project site.
    26
    and that the City’s MND “does not allow for consideration of
    alternatives.” Dr. King also expressed his concern that the MND
    “is not adequate for environmental review” of CA-LAN-1352. He
    noted that an “archeological excavation of [the] site . . . is a
    significant undertaking,” and thus, “[a] data recovery design
    should be a part of an environmental impact document” that
    would “describe the proposed excavation program and estimate
    its cost” and “be subject to public review.” In his oral comments
    at the City Council hearing, Dr. King reiterated his concern that
    “an archaeological site is going to be destroyed.” He also asserted
    that the MND is “totally inadequate” because studying the
    impacts on the site “would require a very large archeological
    project,” but apart from referring to “data recovery,” the MND
    does not describe “what the mitigation would be” or “what will
    happen to the site.” At the City Council hearing, Emily Hilfand
    raised similar concerns about CS-CR-3’s proposed excavation
    plan, stating: “The mitigations mentioned in the [MND] for the
    Cornerstone project are also insufficient. Doing a Phase 3
    excavation for an archeological site is not [a] mitigation effort, it’s
    a destructive copout. There will not be a site after this
    development because the hill will be taken down to bedrock as
    mentioned in the project [r]eports.” In addition, CNPS asserted
    in its administrative appeal that the MND was inadequate
    because the boundaries of CA-LAN-1352 needed to be defined to
    determine the project’s impact on the site. These written and
    oral comments were sufficient to inform the City of the alleged
    deficiencies in CS-CR-3, and therefore, to preserve Petitioners’
    claims about those deficiencies for judicial review. (See Santa
    Clarita Organization for Planning the Environment v. City of
    Santa 
    Clarita, supra
    , 197 Cal.App.4th at pp. 1051-1052;
    27
    California Native Plant Society v. County of El 
    Dorado, supra
    ,
    170 Cal.App.4th at p. 1056.)
    C.    An EIR Is Required To Address The Project’s
    Impacts On Cultural Resources
    Appellants do not dispute that the portion of the project
    site that is occupied by CA-LAN-1352 meets the definition of a
    “tribal cultural resource” because it has yielded, or may be likely
    to yield, important historical information. (§ 21074, subd.
    (a)(1)(A).) They also do not dispute that the project may have
    significant impacts on the site’s archeological and paleontological
    resources, and that mitigation is required to reduce those impacts
    to less than significant. Their contention on appeal is that the
    MND’s mitigation measures “ensure that CA-LAN-1352 will be
    avoided and undisturbed by the Project . . . through archeological
    and paleontological and/or Native American expert monitoring
    during all ground disturbing activities.” We conclude, however,
    that substantial evidence supports a fair argument that the
    MND’s measures improperly defer mitigation of the project’s
    impacts on cultural resources, and are insufficient to avoid or
    reduce those impacts to a less than significant level.
    Generally, “‘[i]t is improper to defer the formulation of
    mitigation measures until after project approval; instead, the
    determination of whether a project will have significant
    environmental impacts, and the formulation of measures to
    mitigate those impacts, must occur before the project is approved.’
    [Citations.]” (Oakland Heritage Alliance v. City of Oakland
    (2011) 
    195 Cal. App. 4th 884
    , 906; see also CEQA Guidelines,
    § 15126.4, subd. (a)(1)(B).) “[A]n exception to this general rule
    applies when the agency has committed itself to specific
    28
    performance criteria for evaluating the efficacy of the measures
    to be implemented in the future, and the future mitigation
    measures are formulated and operational before the project
    activity that they regulate begins. [Citation.]” (Center for
    Biological Diversity v. Department of Conservation (2019) 
    36 Cal. App. 5th 210
    , 239.) Thus, “‘“for [the] kinds of impacts for
    which mitigation is known to be feasible, but where practical
    considerations prohibit devising such measures early in the
    planning process . . ., the agency can commit itself to eventually
    devising measures that will satisfy specific performance criteria
    articulated at the time of project approval.”’” (Oakland Heritage
    Alliance v. City of 
    Oakland, supra
    , at p. 906.) “Conversely,
    ‘“[i]mpermissible deferral of mitigation measures occurs when
    [the agency] puts off analysis or orders a report without either
    setting standards or demonstrating how the impact can be
    mitigated in the manner described. . . .’”” (Preserve Wild Santee
    v. City of Santee (2012) 
    210 Cal. App. 4th 260
    , 280-281.)
    Appellants claim that the MND’s mitigation measures are
    sufficient “to ensure that CA-LAN-1352 will be avoided and
    undisturbed” because CS-CR-1 mandates that “the tribal cultural
    resources will be preserved in place,” while CS-CR-3 requires the
    completion of a data recovery program if “preservation becomes
    impossible.” Contrary to their contention, however, neither of
    these measures is designed to ensure the avoidance of CA-LAN-
    1352 as a tribal cultural resource. CS-CR-1 provides for the
    monitoring of ground-disturbing activities with allowances for
    work stoppages so that “appropriate actions” can be taken for any
    significant archeological or paleontological resources that are
    discovered at the site. CS-CR-3 in turn provides for a Phase III
    data recovery excavation program prior to any project-related
    29
    ground disturbance “[i]f avoidance of CA-LAN-1352 is not
    possible.” Yet the MND does not set forth any analysis of
    whether CA-LAN-1352 can be avoided, nor does it specify any
    performance criteria for evaluating the feasibility of avoidance as
    an alternative to excavation. As the trial court observed, an
    important step in determining whether avoidance is feasible
    would be to define the boundaries of the archaeological site.
    However, in their 2014 peer review, Rincon Consultants noted
    that prior studies did not completely define the boundaries of the
    CA-LAN-1352, and that the boundaries would need to be defined
    if the site cannot be avoided by the project. There is nothing in
    the record to suggest that, following the 2014 peer review, the
    City attempted to define the boundaries of CA-LAN-1352 to
    determine if the site could be avoided, or that it was impractical
    or infeasible for the City to make this determination as part of its
    initial review.11 (CEQA Guidelines, § 15126. subd. (a)(1)(B)
    [specific details of mitigation measure may be developed after
    project approval only “when it is impractical or infeasible to
    include those details during the project’s environmental review,”
    11     Appellants assert the City could not identify the precise
    boundaries of CA-LAN-1352 in the MND because applicable law
    precludes the City from publicly disclosing information about the
    location of archaeological sites. (See CEQA Guidelines, § 15120,
    subd. (d); Gov. Code, § 6254, subd. (r).) However, the issue is not
    whether the site’s boundaries should have been disclosed in the
    MND, but whether those boundaries should have been defined by
    the City to determine whether the site could be avoided. There is
    no indication in the record that the City sought to fully define the
    boundaries of CA-LAN-1352 prior to approving the project, and
    neither the City nor Appellants suggested otherwise in the
    proceedings before the trial court.
    30
    and the agency “adopts specific performance standards the
    mitigation will achieve”].)
    On the other hand, the record contains substantial evidence
    to support a fair argument that avoidance of CA-LAN-1352 is not
    feasible based on the existing project footprint. In his February
    2016 letter, Dr. King stated that he specialized in the study of
    the archaeology and history of Native Americans in Southern
    California. He had studied the archeology of the Santa Monica
    Mountains for 54 years. After reviewing the prior studies of
    CA-LAN-1352 and the MND, Dr. King opined that the “proposed
    Cornerstone project will destroy [the] archaeological site,” and
    that “avoidance is not feasible without changing the project
    footprint.” Dr. King offered a similar opinion at the City Council
    hearing, stating: “I’m concerned that an archaeological site is
    going to be destroyed by this project. The [MND] kind of skirts
    around this issue, says maybe it’ll be destroyed. Well, if it’s going
    to be like it’s shown, the site will be destroyed. Once an
    archaeological site is destroyed, it can’t be replaced. . . .” Dr.
    King’s comments thus support a fair argument that the proposed
    monitoring of the project’s extensive grading activities, as
    mandated by CS-CR-1, will be ineffective to avoid the site and the
    significant impacts to it.
    If, as Dr. King opined, avoidance of CA-LAN-1352 is not
    feasible, then CS-CR-3 requires the implementation of a Phase
    III data recovery excavation program. Dr. King explained that a
    proper excavation of the site would be “a significant undertaking”
    in terms of scope and cost. However, the MND does not consider
    whether a large-scale excavation program of the kind described
    by Dr. King would be feasible, and whether alternative measures
    could effectively mitigate the harm caused by the loss of the site.
    31
    Moreover, like CS-CR-1’s avoidance plan, CS-CR-3 improperly
    defers mitigation of the project’s impacts to the site by delaying
    formulation of several components of the data recovery plan until
    some future time. CS-CR-3 simply provides a generalized list of
    measures to be undertaken by a qualified archaeologist and
    Native American monitor, but it does not set forth any
    performance standards or guidelines to ensure that these
    measures will be effective. For instance, the program calls for
    the future “preparation of a technical report” that “shall include a
    mitigation monitoring and reporting plan.” Yet the MND does
    not explain how the undefined monitoring and reporting plan
    would mitigate the potentially significant effects on the site’s
    cultural resources, nor does it specify any criteria for evaluating
    the efficacy of that plan. There is also no indication in the record
    that it was impractical or infeasible for the City to articulate
    specific performance criteria for these data recovery measures at
    the time of project approval. (See, e.g., Preserve Wild Santee v.
    City of 
    Santee, supra
    , 210 Cal.App.4th at p. 281 [city
    impermissibly deferred mitigation where EIR did not state why
    specifying performance standards for mitigation measure “was
    impractical or infeasible at the time the EIR was certified”]; San
    Joaquin Raptor Rescue Center v. County of Merced (2007) 
    149 Cal. App. 4th 645
    , 670 [mitigation improperly deferred where “no
    specific criteria or standard of performance is committed to in the
    EIR”]; Endangered Habitats League, Inc. v. County of Orange
    (2005) 
    131 Cal. App. 4th 777
    , 792 [deferral not proper where
    proposed “mitigation measure does no more than require a report
    be prepared and followed”].)
    In arguing that an EIR is not required to address the
    project’s impacts on cultural resources, Appellants primarily
    32
    challenge the evidentiary value of the comments made by Dr.
    King. Appellants contend that Dr. King’s comments are mere
    “speculation and unsubstantiated opinion.” We disagree. In his
    letter to the City Council, Dr. King set forth his qualifications as
    an expert in Native American archaeology and history. He also
    indicated that his opinions about the project’s impacts on CA-
    LAN-1352 were based on his review of the 2011 study of the site,
    the 2014 peer review, and the MND. Regardless of whether Dr.
    King ever personally inspected the site, he had an adequate
    background and knowledge base to support his opinion about the
    significant effects of the project on the site’s cultural resources.
    (Pocket Protectors v. City of Sacramento (2004) 
    124 Cal. App. 4th 903
    , 928 [“expert opinion if supported by facts, even if not based
    on specific observations as to the site under review” may qualify
    as substantial evidence supporting a fair argument].)
    Appellants further assert that, even if Dr. King’s comments
    reflected a disagreement among experts over the significance
    of the project’s impacts, the City was entitled to rely on the
    expertise of its own consultants, and did so by adopting the
    specific recommendations made by Rincon Consultants in the
    2014 peer review. However, as the trial court noted, this is not
    a case where the experts disagreed about whether a proposed
    project would have a significant effect on the environment. To
    the contrary, Rincon Consultants opined that CA-LAN-1352
    should be avoided, and that a Phase III data recovery program
    should be conducted if avoidance was not feasible. Dr. King
    agreed that data recovery would be required if the project was
    not reconfigured to avoid the site, but opined that the MND’s
    proposed measure, CS-CR-3, did not provide for an adequate
    data recovery program to mitigate the site’s loss.
    33
    Moreover, to the extent there was a conflict in the evidence,
    “‘neither the lead agency nor a court may ‘weigh’ conflicting
    substantial evidence to determine whether an EIR must be
    prepared in the first instance.’” (Citizens for Responsible & Open
    Government v. City of Grand Terrace (2008) 
    160 Cal. App. 4th 1323
    , 1340; see also CEAQ Guidelines, § 15064, subd. (f)(1).) “It
    is the function of an EIR, not a negative declaration, to resolve
    conflicting claims, based on substantial evidence, as to the
    environmental effects of a project.” (Pocket Protectors v. City of
    
    Sacramento, supra
    , 124 Cal.App.4th at p. 935.) Because the
    record contains substantial evidence supporting a fair argument
    that the MND’s measures are inadequate to avoid or mitigate the
    impacts to CA-LAN-1352 “to a point where clearly no significant
    effect on the environment would occur,” an EIR is required to
    consider the project’s impacts on cultural resources. (§ 21064.5.)
    V.    Impacts On Sensitive Plant Species
    Appellants also challenge the trial court’s conclusion that
    an EIR is required to consider the project’s impacts on sensitive
    plant species. They contend that the trial court erred because the
    MND includes three measures that are sufficient to reduce any
    adverse impacts caused by project-related activities, and to offset
    any loss of individual plants through restoration, preservation,
    and enhancement efforts. They further assert that Petitioners
    failed to exhaust administrative remedies as to several of their
    claims about these mitigation measures.
    A.    Relevant Background
    Three plant species considered to be rare, threatened, or
    endangered occur at the project site: the Agoura Hills dudleya,
    34
    the Lyon’s pentachaeta, and the Ojai navarretia. All three plant
    species occur in areas zoned for project-related fuel modification
    activities, such as mowing, pruning, and clearing of brush.12
    Rare plant surveys of the area were conducted in 2007 and 2008
    as part of the AVSP EIR. A biological resources inventory and
    impact analysis, which included a project site field investigation,
    was completed in February 2014, and a supplemental rare plant
    survey of the site was conducted in July 2014.
    According to the results of the July 2014 survey, there are
    142 Agoura Hills dudleya at the project site, including 90 within
    the limits of fuel modification. There is one Lyon’s pentachaeta,
    which also is located within the limits of fuel modification. There
    are 74 Ojai navarretia within the limits of grading, seven within
    the limits of landscaping, and 163 within the limits of fuel
    modification. It is anticipated that the soils in the occupied areas
    will contain seeds of these plant species, and that the number of
    live individual plants at the site will vary each season depending
    on growing conditions. The July 2014 survey also found that all
    three plant species would be potentially susceptible to impacts
    from grading, landscaping, and/or fuel modification activities.
    In adopting the MND, the City concluded that the project’s
    potential impacts to these three plant species were significant,
    but mitigable through the following measures: CS-BIO-1, which
    discusses mitigation for the Agoura Hills dudleya and the Lyon’s
    12    “Fuel modification involves removal of particularly
    flammable vegetation and replacement with more fire resistant
    varieties, and a fuel modification plan must be incorporated as
    a component of a required landscaping plan.” (Endangered
    Habitats League, Inc. v. County of 
    Orange, supra
    , 131
    Cal.App.4th at p. 787, fn. 8.)
    35
    pentachaeta; CS-BIO-3, which addresses mitigation for the Ojai
    navarretia; and CS-BIO-2, which provides for monitoring of fuel
    modification activities for all three species.
    B.    An EIR Is Required To Address The Project’s
    Impacts On Sensitive Plant Species
    In the writ proceedings, the trial court concluded that the
    evidence supported a fair argument that each of the MND’s
    measures would be ineffective to mitigate the potentially
    significant impacts on the sensitive plant species occurring at the
    site. Based on our independent review of the record, we agree
    that there is substantial evidence supporting a fair argument
    that, even with these mitigation measures, the project may have
    a significant environmental impact on sensitive plant species.
    1.     CS-BIO-1
    CS-BIO-1 provides for plant surveys, onsite restoration,
    and offsite preservation and enhancement for the Agoura Hills
    dudleya and the Lyon’s pentachaeta. It states that, prior to the
    issuance of a grading permit, a qualified plant ecologist will
    perform surveys for listed species, including the dudleya and the
    pentachaeta, during the blooming period from April to June. If a
    state or federally listed species is found, avoidance is required
    unless the project applicant provides substantial documentation
    that avoidance would not be feasible or would compromise the
    objectives of the AVSP. Avoidance is defined as a minimum 200-
    foot setback unless an active maintenance plan is implemented.
    If avoidance is not feasible, a qualified ecologist will prepare a
    restoration plan involving salvage and replanting in coordination
    with applicable federal, state, and local agencies. The plan must
    identify the number of plants to be replanted and the methods to
    36
    be used for onsite preservation, and include a monitoring
    program to measure the success of the effort. The required level
    of success is defined as a minimum of three consecutive years of
    growth of a population equal to or greater than that which would
    be lost due to the project. The restoration plan must be
    submitted to the City for approval prior to the issuance of a
    grading permit, and must be implemented prior to completion of
    the project. If approved, the plan requires annual monitoring
    and reporting for a five-year period.
    In seeking writ relief, Petitioners argued that CS-BIO-1 is
    inadequate in several ways, including that it improperly defers
    the formulation of certain mitigation efforts and fails to set forth
    performance criteria to ensure that mitigation would be effective.
    Appellants contend that these claims were never raised in the
    administrative proceedings. The record shows otherwise. In an
    October 2016 letter to the City’s Planning Director, the Santa
    Monica Mountains Conservancy wrote that the MND’s sensitive
    plant measures are deficient because they “are either deferred
    mitigation, vaguely defined, do not mitigate habitat loss, or rest
    on unproven sensitive species reestablishment methods.”
    Similarly, in a March 2017 letter to the City, the environmental
    law firm, Chatten-Brown & Carstens (CBC), stated that these
    measures “are vague, deferred, or ineffective, and will not ensure
    the propagation of rare plant species . . . that would be required
    for the Project’s impacts to remain at a level below significance.”
    The letter also asserted that CS-BIO-1, in particular, improperly
    defers a determination of whether avoidance is feasible and fails
    to specify performance standards for restoration. These
    arguments about CB-BIO-1 accordingly were preserved for
    judicial review.
    37
    Appellants argue that CS-BIO-1 provides sufficient
    mitigation standards to protect the dudleya and pentachaeta
    plants occurring at the site. However, the record contains
    substantial evidence to support a fair argument that this
    measure is inadequate to mitigate the potential impacts to these
    species. First, in adopting each of the plant mitigation measures,
    the City relied on surveys conducted at the project site in 2007,
    2008, December 2013, and July 2014. In an August 2016
    comment letter to the Planning Director, the California
    Department of Fish and Wildlife (CDFW) noted that these
    surveys were outdated, and that the most recent one was done in
    the summer during an ongoing drought. According to the CDFW,
    botanical surveys that are older than two years and performed in
    conditions that do not maximize detection “may overlook the
    presence or actual density of some special status plant species
    on the [p]roject site.” The CDFW therefore recommended that
    “additional botanical surveys be conducted at the appropriate
    time of year with proper weather conditions and the results
    incorporated into the environmental document for review and
    comment.” While CS-BIO-1 calls for future surveys during the
    blooming period, there was no showing that it was infeasible for
    the City to perform these surveys prior to project approval so that
    the MND could provide an accurate assessment of the sensitive
    plant populations that may be impacted. (CEQA Guidelines,
    § 15126.4, subd. (a)(1)(B).)
    Second, CS-BIO-1 provides for a restoration plan involving
    salvage and replanting if avoidance is not feasible, but there is
    substantial evidence that restoration may not effectively mitigate
    the impacts to the dudleya and pentachaeta species. In its letter,
    the CDFW explained that these species could suffer adverse
    38
    impacts from project-related construction, maintenance, and fuel
    modification activities. The project also could introduce invasive
    ant species onto the habitats occupied by these plants, which
    could interfere with pollination and dispersal. The CDFW
    further stated that the “impacts will continue to be significant
    because CS-BIO-1 will not result in adequate avoidance or
    successful mitigation. . . .” With respect to the restoration plan,
    the CDFW cautioned that “[c]reation or restoration using
    transplanting or topsoil collection should be considered
    experimental in nature and not be considered as a mitigation
    measure” for the dudleya and pentachaeta species. A similar
    observation was made in the 2008 AVSP EIR, which noted that
    “most of the attempts to re-establish Lyon’s pentachaeta have
    failed.” Based on this evidence, it can be fairly argued that
    restoration, whether onsite or offsite, is not an effective form of
    mitigation for these plant species. (California Native Plant
    Society v. County of El 
    Dorado, supra
    , 170 Cal.App.4th at p. 1060
    [substantial evidence supported fair argument that MND’s plant
    restoration measure was inadequate where experts opined that
    transplanting affected species was an “experimental” and
    “unproven method”].)
    Third, the MND defers formulation of certain components
    of CS-BIO-1 without setting specific performance criteria to
    ensure that these measures, as implemented, will be effective.
    For instance, CS-BIO-1 mandates a 200-foot minimum setback to
    avoid dudleya and pentachaeta plants found at the site unless
    “avoidance would not be feasible” or an “active maintenance plan
    is implemented for the known occurrence.” Yet the MND does
    not specify performance standards for determining the feasibility
    of avoidance or for evaluating the efficacy of any maintenance
    39
    plan that may be adopted in lieu of the minimum buffer zone.
    (See Preserve Wild Santee v. City of 
    Santee, supra
    , 210
    Cal.App.4th at p. 281 [“‘EIR is inadequate if “[t]he success
    or failure of mitigation efforts . . . may largely depend upon
    management plans that have not yet been formulated, and have
    not been subject to analysis and review within the EIR”’”].)
    Additionally, while CS-BIO-1 sets standards for measuring the
    success of the restoration plan, it does not provide for any feasible
    alternatives if those salvage and replanting efforts fail. Because
    substantial evidence indicates that restoration may fail, there is
    a fair argument that CS-BIO-1 may be ineffective in offsetting
    the loss of dudleya and pentachaeta plant life at the project site.
    In arguing that CS-BIO-1 provides for sufficient mitigation,
    Appellants contend that the City’s failure to perform updated
    surveys prior to project approval does not reflect any deficiency in
    the MND. It is true, as Appellants assert, that “an agency is not
    required to conduct all possible tests or exhaust all research
    methodologies to evaluate impacts. Simply because an additional
    test may be helpful does not mean an agency must complete the
    test to comply with the requirements of CEQA.” (Save Panoche
    Valley v. San Benito County (2013) 
    217 Cal. App. 4th 503
    , 524.)
    On the other hand, additional testing may be required under
    CEQA “if the initial testing is insufficient.” (Gray v. County of
    Madera (2008) 
    167 Cal. App. 4th 1099
    , 1115.) Here, the MND
    was based on outdated surveys taken in the midst of an ongoing
    drought during which, according to the CDFW, dudleya and
    pentachaeta plants might be difficult to detect. Hence, the
    evidence supported a fair argument that an updated survey
    would not merely be helpful, but would be necessary to formulate
    an adequate mitigation measure for these affected plant species.
    40
    Citing the 2008 AVSP EIR, Appellants also assert that
    restoration of the dudleya and pentachaeta plants is feasible with
    an active management and maintenance plan to monitor success.
    However, as the trial court observed, that prior report stated that
    any success in replanting Lyon’s pentachaeta “would only occur
    for as long as the management occurs,” and that “a site with
    appropriate soils would need to be actively maintained in
    perpetuity.” While CS-BIO-1 requires five years of annual
    reporting and monitoring for its restoration plan, it does not
    provide for active maintenance in perpetuity or alternative
    mitigation measures if the replanting efforts do not succeed.
    Moreover, while the biologists who conducted the 2013 and 2014
    rare plant surveys opined that CS-BIO-1 would reduce impacts
    on the affected plants to a less than significant level, the CDFW
    offered a contrary opinion in its August 2016 comment letter.
    The CDFW’s analysis provides substantial evidence to support a
    fair argument that CS-BIO-1 is inadequate to mitigate the
    project’s potentially significant impacts to the dudleya and
    pentachaeta plant species. (See California Native Plant Society
    v. County of El 
    Dorado, supra
    , 170 Cal.App.4th at p. 1060 [where
    the views of agency biologists about the ineffectiveness of MND’s
    plant mitigation measure conflicted with those of the expert who
    reviewed the project for the developer, the biologists’ “views were
    adequate to raise factual conflicts requiring resolution through
    an EIR”].)
    2.    CS-BIO-3
    CS-BIO-3 requires onsite restoration, offsite preservation,
    or offsite enhancement for the Ojai navarretia. It states that the
    project applicant must offset the loss of individual navarretia
    plants at a 2:1 ratio using one of these methods or another
    41
    mitigation method approved by the City’s Planning Director. A
    plan identifying the location and methodology for satisfying the
    required ratio must be submitted to the City and the CDFW.
    Onsite restoration would involve the collection of seed from inside
    the development footprint and replanting of the seed in a suitable
    area. Offsite preservation would consist of locating a population
    of Ojai navarretia containing at least two times the number of
    individual plants impacted by the project and preserving the
    population in perpetuity. Offsite enhancement would consist of
    locating a disturbed poor quality population of Ojai navarretia
    containing at least two times the number of impacted onsite
    plants and enhancing the conditions of the habitat to promote the
    long-term viability of the population. The selected plan would
    need to be prepared by a qualified plant ecologist and submitted
    to the City for approval prior to the issuance of a grading permit,
    and if approved, it would require maintenance and monitoring by
    the applicant for a minimum of five years. Offsite presentation or
    enhancement is permitted only if the applicant demonstrates
    that onsite restoration is either not feasible or not as likely to be
    successful as the offsite methods.
    Appellants contend that Petitioners’ arguments concerning
    the adequacy of CS-BIO-3 were not raised in the administrative
    proceedings. However, the record reflects that several different
    groups apprised the City of these issues during the public
    comment period. As discussed, the Santa Monica Mountains
    Conservancy objected to the MND’s plant measures on grounds
    that they defer mitigation, are vaguely defined, fail to mitigate
    habitat loss, and rest on unproven restoration methods. At the
    City Council hearing, CNPS’s local chapter president, Snowdy
    Dodson, also raised concerns about the feasibility of restoration,
    42
    noting: “Mitigating the loss of rare plants is next to impossible.
    The rarity means that they are often site-specific for soils and
    climate conditions. Transplanting, seed-sewing, growing in a
    nursery are usually not an option.” In its letter to the City, CBC
    specifically objected to CS-BIO-3 on the grounds that it “is both
    impermissibly deferred and likely ineffective,” and “will not
    mitigate the loss of the 244 individual plants.” The CDFW also
    addressed the likely ineffectiveness of CS-BIO-3 in its comment
    letter. On this record, Petitioners’ arguments regarding CS-BIO-
    3 satisfied the exhaustion requirement.
    The evidence shows that, like CS-BIO-1, CS-BIO-3 may be
    ineffective in mitigating the project’s impacts to sensitive plant
    species. The CDFW’s stated concerns about the unreliability of
    the prior botanical surveys and the need for updated surveys as
    part of the environmental review process applied equally to the
    Ojai navarretia. Moreover, unlike CS-BIO-1, CS-BIO-3 does not
    require that any field surveys be performed prior to the issuance
    of a grading permit. While it is possible, as Appellants assert,
    that the surveys mandated by CS-BIO-1 for “listed plants”
    might include the Ojai navarretia, this species is not listed as
    endangered or threatened under state or federal law. Rather, it
    is considered a special-status species based on the CNPS’s rare
    plant ranking system. Thus, there is uncertainty as to what
    future studies, if any, will be done to obtain accurate, up-to-date
    information about the site’s navarretia population and how it
    may be impacted by the project.
    Additionally, although CS-BIO-3 expressly provides that
    “[o]nsite restoration is preferred” over offsite alternatives, there
    is substantial evidence in the record that replanting the Ojai
    navarretia outside the project footprint may not be a feasible
    43
    mitigation measure. In its comment letter, the CDFW indicated
    that, like the dudleya and pentachaeta species, the navarretia is
    at risk of adverse impacts from the project, including the possible
    introduction of invasive weeds and ant species that may interfere
    with navarretia pollinators and dispersal agents. The CDFW
    further stated that the transplanting of special-status plants was
    uncertain and often failed, and hence, it should “not be viewed as
    a mitigation measure” for the Ojai navarretia. In response to this
    evidence, Appellants again cite to the analysis in the 2008 AVSP
    EIR that active plant management could reduce the impacts to a
    sensitive plant species to a less than significant level. However,
    as discussed, that prior analysis concerned the Lyon’s
    pentachaeta, not the Ojai navarretia. It also made clear that
    active management would need to continue in perpetuity rather
    than the five-year period required by CS-BIO-3.
    Appellants argue that, even if onsite restoration were
    ineffective, CS-BIO-3 provides for offsite preservation and
    enhancement as alternative mitigation measures. Petitioners
    assert that there is no evidence in the record to suggest that
    either of these measures is feasible. Appellants, on the other
    hand, contend that, in the absence of evidence demonstrating
    that these measures are infeasible, any doubts must be resolved
    in favor of the City’s decision. However, under the fair argument
    standard, “‘deference to the agency’s determination is not
    appropriate and its decision not to require an EIR can be upheld
    only when there is no credible evidence to the contrary.’”
    (Georgetown Preservation Society v. County of El Dorado (2018)
    
    30 Cal. App. 5th 358
    , 370; see also Jensen v. City of Santa 
    Rosa, supra
    , 23 Cal.App.5th at p. 884 [fair argument standard “‘creates
    a low threshold requirement for initial preparation of an EIR
    44
    and reflects a preference for resolving doubts in favor of
    environmental review when the question is whether any such
    review is warranted’”].) While the CDFW did not directly address
    the feasibility of offsite preservation or enhancement in its letter,
    it did state that the project’s impacts to the Ojai navarretia
    “would continue to be significant because CS-BIO-3 will not
    result in adequate avoidance or successful mitigation.” The
    CDFW’s opinion constitutes substantial evidence supporting a
    fair argument that, even with CS-BIO-3, the project may have a
    significant impact on the Ojai navarretia species.
    3.     CS-BIO-2
    CS-BIO-2 states that, prior to fuel modification activities
    at the project site, a qualified biologist will locate and flag all
    Agoura Hills dudleya, Lyon’s pentachaeta, and Ojai navarretia
    plants within the fuel modification zone. The biologist will also
    demarcate an appropriate buffer of at least 10 feet, develop and
    implement protocols for protecting the plants in consultation with
    the Los Angeles County Fire Department, and monitor all fuel
    modification activities in these areas. Upon completion of each
    fuel modification effort, the biologist will remove the flagging that
    was used to demarcate the plant locations.
    In the writ proceedings, Petitioners argued that CS-BIO-2
    is infeasible and likely ineffective. While Appellants contend that
    Petitioners failed to exhaust administrative remedies as to this
    claim, the record reflects that the City was fairly apprised of the
    concerns about the MND’s mitigation of impacts to sensitive
    plant species in fuel modification zones. The CDFW specifically
    addressed whether CB-BIO-2 would provide sufficient mitigation
    for these plants in its comment letter. In its letter to the City,
    CBC also stated: “The MND . . . fails to consider the Project’s
    45
    fuel modification zone in its analysis of the Project’s impacts on
    rare and endangered plant species. Fuel modification zones for
    the Project may extend hundreds of feet from the buildings. . . .
    Thus, without disclosure and analysis, this impact cannot have
    been adequately mitigated such that use of an MND is
    appropriate.” Given these public comments, Petitioners’ claims
    about CB-BIO-2 were adequately raised in the administrative
    proceedings.
    In its comment letter, the CDFW expressed the following
    opinion about the efficacy of CB-BIO-2 as a mitigation measure:
    “The effects of entering into vegetative communities supporting
    sensitive plant species for the purposes of clearing wildfire fuel
    is by its nature a disruptive activity with a high probability
    of resulting in incidental take of special status plant species
    including state and federal listed species. Fuel modification also
    alters the ecosystem of the community and may result in direct
    adverse effects to special status plant species. Therefore, CDFW
    is concerned that Mitigation Measure CS-BIO-2 . . . will not
    adequately avoid direct and/or indirect impacts . . . to onsite
    populations of Lyon’s pentachaeta, Agoura Hills dudleya, or the
    Ojai navarretia . . . within the proposed fuel modification zone.”
    The CDFW’s opinion supports a fair argument that CS-BIO-2
    does not provide adequate mitigation for the sensitive plant
    species in the fuel modification zones.
    In arguing that CS-BIO-2 sufficiently mitigates the impacts
    to these plant species, Appellants point out that the monitoring of
    fuel modification activities at the site will take place prior to the
    issuance of a grading permit and continue throughout grading
    and construction. However, as the trial court noted, the City’s
    fuel modification plan for the project indicates that routine
    46
    maintenance activities will be conducted indefinitely. If the
    monitoring required by CS-BIO-2 only occurs through project
    construction, then this measure may be ineffective at mitigating
    the impacts caused by fuel modification activities that occur after
    construction has ended.
    In sum, there is substantial evidence supporting a fair
    argument that the MND’s proposed measures are infeasible or
    inadequate to mitigate the project’s impacts on the Agoura Hills
    dudleya, Lyon’s pentachaeta, and Ojai navarretia to a less than
    significant level. Accordingly, an EIR is required to address the
    potential impacts on these sensitive plant species. (CEQA
    Guidelines, § 15065, subd. (a)(1) [EIR is required where a project
    “has the potential to . . . threaten to eliminate a plant or animal
    community [or] substantially reduce the number or restrict the
    range of an endangered, rare or threatened species”].)
    VI.   Impacts On Native Oak Trees
    In granting writ relief, the trial court concluded that an
    EIR was required to consider the project’s potential impacts on
    native oak trees present at the site. On appeal, Appellants assert
    that Petitioners’ claims about the impacts on oak trees are barred
    by their failure to exhaust administrative remedies. They also
    argue that the mitigation measures in the MND are sufficient
    to reduce the impacts on oak trees to less than significant.
    A.    Relevant Background
    Native oak trees are considered a valuable resource by
    the CDFW, and are protected by the City’s Oak Tree Ordinance.
    (Agoura Hills Municipal Code (Municipal Code), Art. IX, §§ 9657-
    9657.5.) The ordinance includes the City’s Oak Tree Preservation
    47
    Guidelines, which provide for the protection and replacement of
    oak trees that may be disturbed or removed by development in
    the area. (Municipal Code, Art. IX, Appen. A.) The site of the
    project contains oak woodland consisting of valley oaks, coast live
    oaks, and scrub oaks, all of which are protected under the Oak
    Tree Preservation Guidelines.
    According to the MND, there are currently 59 valley oak
    and coast live oak trees and 61,845 square feet of scrub oak
    habitat on the project site. During project construction, 29 of the
    59 valley and coast live oak trees would be removed, and six
    other oak trees would experience encroachment within their
    protected zones. The project also would involve the removal of
    21,271 square feet of scrub oak habitat. Four oak trees that
    stand on the distinctive knoll at the northwest corner of the site
    would be preserved in a newly-constructed plaza.
    In adopting the MND, the City concluded that the project
    would have significant impacts on the site’s oak trees, but that
    such impacts would be reduced to less than significant with two
    mitigation measures, CS-BIO-9 and CS-BIO-10. CS-BIO-9
    generally provides for the replacement of oak trees removed
    during project development, and where onsite replacement is
    not feasible, it allows for an in-lieu fee to be paid to the City to
    acquire land to plant new oak trees. CS-BIO-10 requires that,
    prior to the issuance of a grading permit, the project applicant
    must submit an oak tree survey, an oak tree report, and an oak
    tree preservation program for review and approval by the City.
    48
    B.    Petitioners Exhausted Administrative
    Remedies As To The Oak Tree Claims
    In their brief before the trial court, Petitioners contended
    that the MND fails to adequately analyze and mitigate the
    project’s impacts on oak trees, including water loss caused by
    mass grading. Petitioners also argued that the MND’s mitigation
    measures are uncertain and ineffective, and improperly defer
    various aspects of mitigation such as the in-lieu fee payment. On
    appeal, Appellants claim that Petitioners failed to meet their
    burden of showing that these specific issues were presented in
    the administrative proceedings. We disagree.
    The record reflects that the City’s Oak Tree Consultant and
    Appellants’ landscape architect each described the risk that mass
    grading would result in a water deficit to the oak trees at the
    project site. These experts also discussed the removal of scrub
    oaks due to fuel modification activities and the efficacy of
    replacing them with smaller trees. In addition, various
    environmental groups informed the City of their concerns about
    the project’s impacts on oak trees and the adequacy of the MND’s
    mitigation measures. For instance, in its appeal letter, CNPS
    wrote that the MND “does not adequately analyze environmental
    consequences to the oak population at the project site,” and that
    “[t]he ‘mitigation’ for this capacious and significant take is to
    authorize an Oak Tree Permit, a variance, a small percentage of
    onsite mitigation, with [an] undisclosed and vague promise to
    plant oaks at an in lieu fee location.” A local CNPS member
    reiterated these concerns at the City Council hearing, noting:
    “The mitigation for the oak tree removal is not consistent with
    the Specific Plan. It uses . . . replacement specimens that are
    considerably smaller. It offers no monitoring plan to ensure the
    49
    long-term viability of the oaks and it doesn’t address the
    associated plants that go along with an oak community.” At the
    same hearing, a local resident specifically complained that the
    mass grading required by the project would interrupt the
    subsurface water flow to both retained and replacement oak
    trees.
    Other written and oral comments presented to the City
    questioned the adequacy of mitigation through replanting of trees
    and payment of an in-lieu fee. In a March 2017 letter to the City,
    the Conejo Oak Tree Advocates (COTA) objected to the in-lieu fee
    option, noting: “[T]he Mitigation Measures and Conditions allow
    the applicant to pay a fee in lieu of . . . replacement of destroyed
    trees. This possibility is a tremendous loss to your community.”
    COTA urged the City to reconsider the measure because it would
    allow “eliminating 59% of City protected Valley oak and Coast
    Live oak trees on this site by simply paying a fee.” At the City
    Council hearing, a member of COTA raised a similar concern
    about allowing the project to “pay an in lieu fee instead of
    replanting,” and asked the City to prepare a “full EIR that offers
    . . . options with less impacts.” In its letter to the City, CBC
    specifically asserted that CS-BIO-9 would not be an effective
    measure, stating: “CS-BIO-9 . . . permits payment of an in-lieu
    fee instead of replacement of the 29 trees that will be removed if
    space is not available for replanting. This does not mitigate the
    loss of oak woodlands on the site and will result in a new loss of
    oak trees in Agoura Hills. Even if trees are replanted onsite or
    offsite, grading and drainage alterations to the site will reduce
    the ability of replanted oak trees to survive and thrive.”
    Considering the totality of this record, Petitioners preserved each
    of their oak tree claims for judicial review.
    50
    C.    An EIR Is Required To Address The Project’s
    Impacts On Oak Trees
    Appellants contend that an EIR is not necessary to consider
    the project’s potential impacts to native oak trees because CS-
    BIO-9 and CS-BIO-10 provide feasible and effective measures for
    mitigating those impacts. We conclude, however, that there is
    substantial evidence supporting a fair argument that the MND
    does not adequately analyze the significant impacts that the
    project may have on the site’s oak trees, nor does it effectively
    mitigate those potential impacts to a less than significant level.
    1.     CS-BIO-9
    CS-BIO-9 provides for the replacement of oak trees that are
    removed for development. It states that four oak trees will be
    planted to replace each tree that is approved for removal. For
    impacts involving 10 percent or less of oak tree removal, each oak
    tree must be replaced onsite with trees of the same species. For
    impacts involving greater than 10 percent of oak tree removal,
    trees must be replaced onsite or an in-lieu fee must be paid to the
    City to acquire land or plant new oak trees on another site. To
    mitigate the removal of 21,271 square feet of scrub oak habitat,
    at least 213 five-gallon scrub oak trees must be planted onsite. If
    the City’s Planning Director or Oak Tree Consultant determines
    that the onsite planting of the required number of scrub oak trees
    is not feasible, then an equivalent in-lieu fee must be paid into
    the City’s Oak Tree Mitigation Fund.
    The evidence in the record supports a fair argument that
    CS-BIO-9 is inadequate to mitigate the significant impacts on
    oak trees. First, the record contains substantial evidence that
    mass grading from the project may cause a loss of water to both
    51
    the retained and replacement trees. According to the 2008 Oak
    Tree Report prepared by Appellants’ consultant: “Mass grading
    of a site . . . will disrupt the natural subsurface water flowing
    along the bedrock and supplying moisture to the trees. This will
    likely cause a water deficit to indigenous oaks of this site.” The
    report noted that “[i]t will be necessary to immediately respond to
    this problem by establishing a method for replacing this water
    loss.” In 2014, the City’s Oak Tree Consultant similarly opined
    that there would be impacts to the retained oaks from the “severe
    alteration of underground water availability as a result of grade
    alteration.” The City’s consultant recommended that the project
    arborist “provide supplemental irrigation details in order to
    mitigate for the loss of seasonal flow from upslope.” At the City
    Council hearing, an individual named Jess Thomas expressed
    similar concerns about “the effect of the required grading on the
    remaining and replacement oak trees.” Thomas explained that
    “mass grading severely interrupts the natural waterways
    underneath the earth,” which would impact the ability of “all of
    the oak trees” on the site to survive. Despite these risks from
    mass grading, CS-BIO-9 does not include any provisions for
    mitigating the loss of water for the retained or replacement trees.
    Moreover, while the MND states that the retained oaks will have
    “no direct construction impacts,” it fails to provide any analysis of
    the potential impacts to trees from the disruption of subsurface
    water flow.
    Second, there is substantial evidence that prior efforts at
    oak tree restoration have failed. In a September 2016 letter to
    the City’s Planning Director, the Resources Conservation District
    of the Santa Monica Mountains reported: “To date, there have
    been no successful restorations of oak woodlands. It is relatively
    52
    easy to plant oak trees, but the extensive ecological network and
    soils that make a forest from those trees has been thus far
    impossible to recreate.” In its comment letter, CBC similarly
    stated that [a]ttempts to recreate oak woodlands as mitigation for
    other developments are often unsuccessful.” In addition, CNPS
    cautioned that planting a boxed tree from a nursery would not
    mitigate the loss of fauna and plant life that are part of the oak
    community. As the trial court noted, the MND contains no
    analysis showing that CS-BIO-9 would be likely to succeed in
    recreating or restoring the oak woodland lost to project
    development.
    Third, the evidence supports a fair argument that CS-BIO-
    9 improperly defers formulation of the in-lieu fee program as an
    alternative to onsite tree replacement. “In-lieu fee programs . . .
    may offer the best solution to environmental planning challenges,
    by providing some certainty to developers while adequately
    protecting the environment. But in order to provide a lawful
    substitute for the ‘traditional’ method of mitigating CEQA
    impacts, that is, a project-by-project analysis, the fee program
    must be evaluated under CEQA. [Citation.]” (California Native
    Plant Society v. County of El 
    Dorado, supra
    , 170 Cal.App.4th
    at p. 1053.) Here, CS-BIO-9 provides that the in-lieu fee
    payment will be used by the City to acquire land or plant oak
    trees on another site, preferably in close proximity to the
    removed trees. However, the MND does not specify the fees to be
    paid or the number of trees to be planted offsite, nor does it
    identify whether any other sites might be available to the City for
    the planting of new oak trees. The MND also does not contain
    any analysis of the feasibility of an offsite tree replacement
    program. Given the evidence that prior efforts to recreate oak
    53
    woodlands have been unsuccessful, it cannot be presumed that
    the offsite planting of oak trees through an in-lieu fee payment is
    a feasible alternative to the onsite replacement of oak trees in
    their native habitat. (Id. at p. 1059 [payment of in-lieu fee
    pursuant to county ordinance did not eliminate need for EIR
    because, “in the absence of any environmental review, [a fee
    ordinance] does not presumptively establish full mitigation” for a
    given project].)
    In arguing that CS-BIO-9 adequately mitigates the impacts
    on oak trees, Appellants note that state law allows mitigation
    through funds contributed for oak tree conservation. They cite
    section 21083.4, subdivision (b), which states that if a county
    determines that a project may have a significant effect on oak
    woodlands, it may contribute funds to the state’s Oak Woodlands
    Conservation Fund for the purpose of purchasing oak woodlands
    conservation easements. However, as the trial court pointed out,
    that statute applies to county contributions to a state-run fund,
    whereas CS-BIO-09 requires payment to the City to acquire land
    or locate another site to plant new trees. In any event, section
    21083.4 does not relieve the City of its obligation to analyze the
    in-lieu fee measure under CEQA to determine if it adequately
    mitigates this project’s impacts “to a point where clearly no
    significant effect on the environment would occur.” (§ 21064.5.)
    Appellants also assert that CS-BIO-9 provides for sufficient
    mitigation because it includes various requirements to maximize
    the viability of the replaced oak trees, such as replanting trees in
    their species-specific habitat, adopting a preference for planting
    mature oaks within the site, and mandating agency review of
    project plans. However, as discussed, none of the provisions in
    CS-BIO-9 address the risk of a subsurface water deficit due to
    54
    mass grading, even though the experts for both Appellants and
    the City opined that it was necessary to establish a method for
    replacing this water loss to the oak trees. The MND does not
    discuss this potentially significant impact, nor does it evaluate
    the evidence that prior attempts to restore oak woodlands have
    failed. (See Nelson v. County of Kern (2010) 
    190 Cal. App. 4th 252
    ,
    267 [EIR required where agency “fails to gather information and
    undertake an adequate environmental analysis in its initial
    study’”]; Sundstrom v. County of Mendocino (1988) 
    202 Cal. App. 3d 296
    , 311 [“[w]here the local agency has failed to
    undertake an adequate initial study,” it “should not be allowed to
    hide behind its own failure to gather relevant data”].) Based on
    this record, substantial evidence supports a fair argument that
    CS-BIO-9 is inadequate to reduce the project’s impacts to oak
    trees to a less than significant level.13
    13     Petitioners contend that the MND also fails to analyze and
    mitigate the impacts to scrub oaks that may result from being
    replaced with smaller-sized trees and from fuel modification
    activities that may require extensive pruning. While the trial
    court found that the evidence did not support a fair argument
    regarding these particular contentions, it concluded that an
    EIR was required based on Petitioners’ other oak tree claims.
    Because we agree that an EIR is required to consider the project’s
    impacts on oak trees, we need not address Petitioners’ specific
    arguments regarding the adequacy of the MND’s mitigation
    measures for scrub oaks. In accordance with CEQA, the EIR
    prepared by the City must clearly identify and describe all
    significant effects of the project on the environment, and discuss
    feasible mitigation measures for each significant environmental
    effect that is identified. (§ 21100, subd. (b); CEQA Guidelines,
    §§ 15126.2, subd. (a), 15126.4, subd. (a)(1).)
    55
    2.     CS-BIO-10
    CS-BIO-10 requires the project applicant to submit the
    results of an oak true survey and an oak tree report, including an
    oak tree preservation program, for review and approval by the
    City prior to the issuance of a grading permit. The project must
    be developed and operated in compliance with the approved oak
    tree preservation program and any other conditions determined
    to be necessary by the City’s Oak Tree Consultant. The program
    must include a number of components, including restrictions on
    grading and construction-related activities near the driplines of
    trees, limits on irrigation and watering, and requirements for
    fencing, trenching, and pruning. Under the program, the health
    of the retained oak trees must be assessed prior to construction,
    and any trees in a weakened condition must be treated to
    invigorate them. The health of the trees also must be monitored
    during all phases of construction, and any problems that are
    detected must be properly addressed.
    The record contains substantial evidence that CS-BIO-10
    may not be effective in reducing the project’s impacts on oak trees
    to less than significant. Like CS-BIO-9, CS-BIO-10 does not
    address the risk that mass grading may disrupt the subsurface
    water flow at the project site and cause a water deficit to the
    site’s oak trees. Appellants claim that CS-BIO-10 is sufficient to
    mitigate the risk of water loss because it provides for an oak tree
    preservation program with several components that are designed
    to ensure the health of the retained oak trees. However, the
    program’s components are primarily aimed at protecting the oak
    trees from damage caused by encroachment during grading and
    construction. They do not address the long-term survival of the
    retained or replacement oak trees whose natural source of water
    56
    is reduced by mass grading. While Appellants point to the
    program’s watering and irrigation requirements as an example of
    potential mitigation, those provisions actually limit the supply of
    water to the oak trees by prohibiting permanent irrigation and
    watering during the summer months. Neither these components
    nor any others required by an oak tree preservation program
    provide for lost water to be replaced. Because substantial
    evidence supports a fair argument that, even with CS-BIO-9 and
    CS-BIO-10, the project may have significant impacts on native
    oak trees, an EIR is required to address those potential impacts.
    VII. Impacts On Aesthetic Resources
    In granting the writ petition for violation of CEQA, the
    trial court concluded that there was substantial evidence to
    support a fair argument that the project may have significant
    impacts on the aesthetic resources of the site, and that the MND
    is inadequate to mitigate those impacts to less than significant.
    On appeal, Appellants do not challenge the merits of the trial
    court’s ruling on the project’s impacts to aesthetic resources.
    Rather, their sole contention is that Petitioners failed to exhaust
    administrative remedies as to their aesthetic resource claims.14
    14    Appellants’ reply brief includes a single, isolated reference
    to the merits of the Petitioners’ claims. It states that “there is no
    substantial evidence supporting a fair argument that significant
    aesthetic impacts remain.” This conclusory assertion is not
    accompanied by any discussion explaining why Petitioners’
    claims lack merit or why the trial court’s ruling was incorrect.
    On appeal, “‘“the party asserting trial court error may not . . .
    rest on the bare assertion of error but must present argument
    and legal authority on each point raised. [Citation.]” [Citations.]
    When an appellant raises an issue “but fails to support it with
    57
    The MND states that “[t]he mature oak trees on the project
    site offer a scenic resource, with the distinct example being the
    knoll of oak trees on the northwestern corner of the project site.”
    In adopting the MND, the City concluded that the potential
    development of this knoll was a significant impact, but was
    mitigatable through measure AES-3. AES-3 requires the project
    applicant to “avoid development, removal, or reduction . . . of that
    knoll,” and to minimize grading and other earthwork in the area
    “in order to avoid substantially modifying a scenic resource.” The
    City also concluded that the removal of oak trees at the site was a
    potentially significant impact, but that CS-BIO-9 and CS-BIO-10
    “would reduce the visual impacts related to the removal of oak
    trees to a less than significant level.”
    In seeking writ relief, Petitioners argued that the City
    incorrectly had concluded that the MND’s measures adequately
    mitigated the project’s impacts on aesthetic resources. With
    respect to the scenic knoll, Petitioners asserted that the knoll’s
    oak trees were at risk for harm from project construction and
    reasoned argument and citations to authority, we treat the point
    as waived.”’” (Hernandez v. First Student, Inc. (2019) 
    37 Cal. App. 5th 270
    , 277; see also Public Employment Relations Bd.
    v. Bellflower Unified School Dist. (2018) 
    29 Cal. App. 5th 927
    , 939
    [“‘“[w]e are not bound to develop appellants’ argument for them[;]
    . . . [t]he absence of cogent legal argument or citation to authority
    allows this court to treat the contention as waived”’”]; Allen v.
    City of Sacramento (2015) 
    234 Cal. App. 4th 41
    , 52 [“[w]hen legal
    argument with citation to authority is not furnished on a
    particular point, we may treat the point as forfeited and pass
    it without consideration”].) Because Appellants do not make any
    reasoned argument as to whether the MND adequately mitigates
    the project’s aesthetic impacts, that issue has been forfeited.
    58
    changes in subsurface water flow caused by mass grading, and
    that there was no substantial evidence that any of the MND’s
    mitigation measures, including AES-3, would effectively protect
    those trees. With respect to the removal of the oak trees,
    Petitioners argued that there was no substantial evidence that
    CS-BIO-9 and CS-BIO-10 would adequately mitigate the harm
    to scenic resources caused by the loss of the trees. Petitioners
    specifically contended that CS-BIO-9’s allowance of a fee
    payment in lieu of planting new trees would not reduce the
    impacts on aesthetic resources at the site, and that CS-BIO-10
    would not protect the long-term survival of the site’s oak trees.
    Petitioners also noted that several of the trees to be removed
    were among the largest and most vigorous oaks, and that the
    MND did not address this significant scenic loss.
    Appellants assert that none of Petitioners’ claims about the
    project’s impacts on aesthetic resources were presented in the
    administrative proceedings. However, our independent review
    of the record demonstrates that Petitioners satisfied the
    exhaustion requirement as to each of these claims. During the
    public comment period, a number of individuals and groups
    raised issues about the project’s aesthetic impacts. For instance,
    in a March 2017 email to the City Council, a local resident wrote
    that he was “opposed to this monstrous project moving forward in
    its current state,” and was “particularly distressed at the planned
    destruction of countless oak trees” because the “plants and
    habitat of our beautiful hills, with all of the gorgeous oaks
    populating these hillsides [are] what makes us unique.” In a
    March 2017 comment letter, the group Save Open Space (SOS)
    stated that the project would “substantially degrade the existing
    visual character of the site,” including its “natural steep oak
    59
    studded hillside” and “distinctive topographical feature which is
    the large natural corner knoll.” At the City Council hearing, an
    SOS member reiterated these concerns, noting: “[T]he vast
    majority of the steep, . . . oak-studded hillside will be replaced by
    buildings which will degrade a major view for all parts of our
    City.” She added that the “corner knoll is not being preserved.”
    CBC also addressed the project’s aesthetic impacts in its
    comment letter, stating that “[t]he conversion of a scenic knoll
    into seven three-story buildings, along with the removal of 29
    trees and 95,000 cubic yards of grading will cause significant
    adverse impacts to the visual quality of the site.”
    In addition to receiving these comments about the project’s
    adverse aesthetic impacts, the City was fairly apprised of the
    concerns about water loss to the oak trees from mass grading. As
    discussed, experts for both the City and Appellants explained
    that mass grading at the site could disrupt subsurface water flow
    to the oak trees, and recommended that a method of replacing
    this water loss be implemented. The City’s Oak Tree Consultant,
    in particular, reported that the oaks on the knoll “would require
    supplemental irrigation” as a result of “the interruption of sheet
    flow from upslope.” She also advised the City to reconsider
    removing certain valley oak trees because they were the largest
    and most vigorous specimens on the site. The record further
    reflects that the City was fairly apprised of the concern that the
    MND’s in-lieu fee measure would not effectively mitigate the
    project’s impacts to the oak trees. As described, COTA objected
    to using an in-lieu fee to replace the loss of 29 oak trees in both
    its written and oral comments to the City. In their respective
    letters to the City, CBS asserted that the in-lieu fee would “not
    mitigate the loss of oak woodlands on the site,” and CNPS
    60
    characterized the measure as an “undisclosed and vague promise
    to plant oaks” at another location. On this record, Petitioners
    adequately exhausted administrative remedies as to each of their
    aesthetic resource claims.
    VIII. Violation Of Oak Tree Ordinance
    In addition to the CEQA cause of action, the petition for
    writ of mandate alleged a cause of action for violation of the
    City’s Oak Tree Ordinance. In granting the petition as to this
    claim, the trial court concluded that the oak tree permit issued by
    the City violated the ordinance’s prohibition on the removal of
    more than 10 percent of the total estimated tree canopy. On
    appeal, Appellants do not present any argument regarding the
    merits of the trial court’s ruling.15 Instead, they assert that
    Petitioners did not raise the City’s compliance with the ordinance
    in the administrative proceedings, and therefore, failed to
    exhaust their administrative remedies as to this claim.
    15     As with the issue of aesthetic impacts, Appellants’ briefing
    on appeal includes a conclusory assertion that the trial court
    erred in finding that City’s issuance of the oak tree permit
    violated the Oak Tree Ordinance as to the number of affected
    trees. However, Appellants do not make any cognizable claim of
    error with respect to the trial court’s conclusion that the City
    violated the ordinance’s 10-percent rule, nor do they offer any
    factual or legal basis for determining that there was statutory
    compliance. Appellants therefore have forfeit any challenge to
    the merits of the trial court’s ruling. (Hernandez v. First Student,
    
    Inc., supra
    , 37 Cal.App.5th at p. 277; Public Employment
    Relations Bd. v. Bellflower Unified School 
    Dist., supra
    , 29
    Cal.App.5th at p. 939; Allen v. City of 
    Sacramento, supra
    , 234
    Cal.App.4th at p. 52.)
    61
    The City’s Oak Tree Ordinance requires a permit to cut,
    prune, remove, or encroach into the protected zone of an oak tree.
    (Municipal Code, § 9657.5.) An oak tree permit may be issued to
    a project applicant if the City finds that the continued existence
    of the affected oak tree prevents the development of the project;
    however, the applicant may not request the removal of more than
    10 percent of the total estimated tree canopy or root structure of
    all trees on the subject property. (Id. at § 9657.5, subd. (C)(3)(c).)
    In seeking writ relief, Petitioners argued that the City violated
    the ordinance in issuing an oak tree permit for the project
    because, among other reasons, the permit allowed for the removal
    of more than 10 percent of the oak tree canopy on the project site.
    The trial court agreed, noting that the City’s own consultant had
    advised the City that the project would result in the removal of
    35 to 36 percent of the oak trees, and thus, exceed the amount
    permitted by the Oak Tree Ordinance.
    Appellants contend that the issue of statutory compliance
    with the ordinance’s 10-percent removal limitation was not
    presented to the City in the administrative proceedings. The
    record shows, however, the City clearly was apprised of the issue.
    In a May 23, 2014 memorandum to the Planning Director, the
    Oak Tree Consultant for the City explained that her analysis
    showed that “36 percent of the coast live oak and valley oak trees
    will be removed,” and that the “Municipal Code states that not
    more than 10 percent of the total estimated tree canopy or root
    structure of all trees on the site may be removed.” In a June 29,
    2015 memorandum, the Oak Tree Consultant again advised the
    City’s Planning Director that the proposed development would
    require the removal of 35 to 36 percent of the oak tree canopy,
    62
    and that the “overall impact therefore exceeds the impact
    permitted by the Zoning Code.”
    A number of groups and individuals also raised this issue
    in their oral and written comments to the City. In a March 2017
    letter to the City, SOS quoted the exact language of Municipal
    Code section 9657.5, subdivision (C)(3)(c), and explained that
    “[t]he proposed development violates the 10% rule.” In its appeal
    letter, CNPS likewise cited the relevant provision of the
    ordinance in asserting that “[t]he rules specify that no more than
    10% of the oak population shall be removed for any project,” and
    that the applicant “proposes removal of over 40% of all three oak
    species.” At the City Council hearing, an SOS representative
    pointed out that the “proposed project is cutting down 36% of the
    oaks, when a maximum of 10% is allowed.” Another speaker
    focused her remarks exclusively on the City’s lack of compliance
    with the 10-percent rule, stating: “The maximum number of oak
    trees which you can authorize for removal pursuant to Zoning
    Code Section 9657.5 which you should have in front of you, is 10%
    . . ., but [what] you’ve been requested to approve is far greater
    than that. . . . Therefore, the Planning Commission erred in
    granting an oak tree permit allowing for more than 10% of the
    trees to be removed plain and simple. You do not have the right
    to approve a permit that violates the City’s duly adopted law.”
    Once again, Appellants’ exhaustion claim lacks merit.
    IX.   Award of Attorney’s Fees
    Appellants challenge the trial court’s award of attorney’s
    fees to Petitioners on two grounds. First, Appellants contend
    that Petitioners are not entitled to any attorney’s fees because
    they failed to provide notice of the CEQA action to the Attorney
    63
    General in accordance with section 21167.7 and Code of Civil
    Procedure section 388. Second, Appellants claim that the trial
    court erred in concluding that Gelfand was personally liable for
    50 percent of the fee award.
    A.    Governing Law
    Code of Civil Procedure section 1021.5 provides in relevant
    part: “Upon motion, a court may award attorneys’ fees to a
    successful party against one or more opposing parties in any
    action which has resulted in the enforcement of an important
    right affecting the public interest if: (a) a significant benefit,
    whether pecuniary or nonpecuniary, has been conferred on the
    general public or a large class of persons, (b) the necessity and
    financial burden of private enforcement, or of enforcement by one
    public entity against another public entity, are such as to make
    the award appropriate, and (c) such fees should not in the
    interest of justice be paid out of the recovery, if any.”
    Accordingly, “‘[t]o obtain attorney fees under [Code of Civil
    Procedure] section 1021.5, the party seeking fees must show that
    the litigation: “‘“‘(1) served to vindicate an important public right;
    (2) conferred a significant benefit on the general public or a large
    class of persons; and (3) [was necessary and] imposed a financial
    burden on plaintiffs which was out of proportion to their
    individual stake in the matter.’ [Citation.]” [Citation.]’”
    [Citations.] Because the statute states the criteria in the
    conjunctive, each must be satisfied to justify a fee award.
    [Citations.]’ [Citation.]” (City of Maywood v. Los Angeles
    Unified School Dist. (2012) 
    208 Cal. App. 4th 362
    , 429.)
    An award of attorney’s fees under Code of Civil Procedure
    section 1021.5 generally is reviewed on appeal for abuse of
    64
    discretion. (Laffitte v. Robert Half Internat. Inc. (2016) 
    1 Cal. 5th 480
    , 488; Serrano v. Stefan Merli Plastering Co., Inc. (2011) 
    52 Cal. 4th 1018
    , 1025.) “‘Fees approved by the trial court are
    presumed to be reasonable, and the objectors must show error in
    the award.’ [Citation.]” (Laffitte v. Robert Half Internat. 
    Inc., supra
    , at p. 488.) “‘“However, de novo review of such a trial court
    order is warranted where the determination of whether the
    criteria for an award of attorney fees and costs in this context
    have been satisfied amounts to statutory construction and a
    question of law.”’ [Citation.]” (Conservatorship of Whitley (2010)
    
    50 Cal. 4th 1206
    , 1213.) Under some circumstances, determining
    whether the criteria for a fee award are satisfied may involve
    “a mixed question of law and fact and, if factual questions
    predominate, may warrant a deferential standard of review.”
    (Connerly v. State Personnel Bd. (2006) 
    37 Cal. 4th 1169
    , 1175.)
    B.    CEQA’s Notice Requirement Does Not Preclude
    Petitioners From Recovering Attorney’s Fees
    Appellants argue that Petitioners cannot satisfy the
    necessity and financial burden criteria of Code of Civil Procedure
    section 1021.5 because they did not timely serve the Attorney
    General with a copy of their first amended petition as required by
    section 21167.7 and Code of Civil Procedure section 388. Section
    2116.7 states, in relevant part, that every person who brings a
    CEQA action “shall . . . furnish pursuant to Section 388 of the
    Code of Civil Procedure a copy of any amended or supplemental
    pleading filed by such person in such action to the Attorney
    General. No relief, temporary or permanent, shall be granted
    until a copy of the pleading has been furnished to the Attorney
    General in accordance with such requirements.” Code of Civil
    65
    Procedure section 388 in turn provides that “the party filing the
    pleading shall furnish a copy to the Attorney General of the State
    of California . . . within 10 days after filing.”
    In this case, it is undisputed that Petitioners filed the
    original petition for writ of mandate on April 7, 2017, and mailed
    a copy of the petition to the Attorney General five days later on
    April 12, 2017. Petitioners filed the first amended petition on
    August 10, 2017; however, they did not mail a copy of that
    amended petition to the Attorney General until five months later
    on January 20, 2018. Appellants assert that Petitioners’ failure
    to serve the Attorney General with a copy of the first amended
    petition within 10 days of filing precluded the trial court from
    granting them any relief, including attorney’s fees under Code of
    Civil Procedure section 1021.5.
    In support of this argument, Appellants cite the decision
    in Schwartz v. City of Rosemead (1984) 
    155 Cal. App. 3d 547
    (Schwartz). In Schwartz, the plaintiff successfully obtained a
    writ of mandate ordering the defendant city to conduct an
    environmental assessment pursuant to CEQA of a proposed
    cogeneration plant near the plaintiff’s property. (Id. at p. 554.)
    In affirming the trial court’s denial of the plaintiff’s request for
    attorney’s fees, the appellant court concluded that the plaintiff
    was not entitled to attorney’s fees under Code of Civil Procedure
    section 1021.5 because the financial burden that he undertook in
    pursuing the action was not out of proportion to his personal
    interest in the case. (Id. at p. 560.) The court also concluded that
    the plaintiff’s failure to timely serve the Attorney General with a
    copy of the pleadings refuted a showing of the necessity and
    financial burden of private enforcement. (Id. at pp. 560-561.)
    As the court explained: “[Plaintiff’s] failure to comply with the
    66
    statutory requirements of serving a copy of his pleading to the
    Attorney General within 10 days of filing effectively precluded
    the Attorney General from exercising an informed decision
    regarding intervention in this action. If the Attorney General
    had been promptly notified of [plaintiff’s] action and had decided
    to intervene, [plaintiff] may not have been required to pursue his
    lawsuit to the extent he ultimately did. The service of pleadings
    on the Attorney General has the effect of informing that office of
    the action and permits the Attorney General to lend its power,
    prestige, and resources to secure compliance with CEQA and
    other environmental laws, perhaps without the necessity of
    prolonged litigation. If the Attorney General is properly served
    and elects not to intervene, then a plaintiff's pursuit of a lawsuit
    becomes presumptively ‘necessary.’” (Id. at p. 561.)
    Contrary to Appellants’ contention, Petitioners are not
    barred from recovering attorney’s fees based on their failure to
    strictly comply with the 10-day notice requirement of section
    21167.7 and Code of Civil Procedure section 388. First, as our
    Supreme Court has recognized, these statues do “not make such
    notification a prerequisite to recovering fees” under Code of Civil
    Procedure section 1021.5. (Vasquez v. State of California (2008)
    
    45 Cal. 4th 243
    , 258.) Instead, in determining in a particular case
    “whether private enforcement was sufficiently necessary to
    justify an award of fees, the trial court exercises its equitable
    discretion in light of all the relevant circumstances.” (Id. at
    pp. 258-259, fn. omitted.) The Schwarz court likewise
    acknowledged that a lack of compliance with CEQA’s notice
    requirement was not an absolute bar to attorney’s fees, noting
    that “situations may exist where these statutory provisions
    67
    should not be strictly followed.” 
    (Schwartz, supra
    , 155
    Cal.App.3d at p. 561.)
    Second, the reasoning in Schwarz for denying attorney’s
    fees does not apply to the facts of this case. In Schwartz, the
    plaintiff served the Attorney General with a copy of his pleadings
    34 days after the filing of the action and only four days before the
    hearing on his writ petition. 
    (Schwartz, supra
    , 155 Cal.App.3d at
    p. 561.) As a result, the Attorney General’s office advised the
    defendant city that, due to the plaintiff’s late service, it did not
    have an opportunity to conduct even a preliminary review of the
    petition prior to the hearing. 
    (Schwartz, supra
    , 155 Cal.App.3d
    at p. 560.) Here, Petitioners served the Attorney General with a
    copy of their original petition five days after it was filed and 11
    months before the first writ hearing. The first amended petition,
    which was not materially different from the original petition, was
    served on the Attorney General a month and a half before that
    hearing. The Attorney General therefore had ample time to
    intervene and did not do so, making private enforcement of the
    action necessary. (Conservatorship of 
    Whitley, supra
    , 50 Cal.4th
    at p. 1217 [“the ‘necessity . . . of private enforcement’ has long
    been understood to mean simply that public enforcement is not
    available, or not sufficiently available”].)
    Appellants also contend that the trial court erred in
    admitting a declaration from Petitioner’s attorney, which
    described when the copies of the original and first amended
    petitions were mailed to the Attorney General and attached
    copies of those notices. Appellants objected to the declaration on
    the grounds that it was submitted with Petitioner’s reply brief,
    was not part of the administrative record, and did not meet the
    requirements for a proof of service under Code of Civil Procedure
    68
    section 1013a. We conclude, however, that the trial court did
    not abuse its discretion in admitting the challenged evidence.
    (Litinsky v. Kaplan (2019) 
    40 Cal. App. 5th 970
    , 988 [trial court’s
    ruling on the admissibility of evidence is reviewed for abuse of
    discretion]; accord, Dart Industries, Inc. v. Commercial Union
    Ins. Co. (2002) 
    28 Cal. 4th 1059
    , 1078.)
    Because Appellants first raised the issue of notice to
    the Attorney General in their opposition to the writ petition,
    Petitioners properly responded in their reply by submitting a
    declaration from their attorney that addressed this specific
    evidentiary issue. (Jay v. 
    Mahaffey, supra
    , 218 Cal.App.4th at
    p. 1538 [evidence submitted with reply may be admissible where
    it “fill[s] gaps in the evidence created by the . . . opposition”]).
    Additionally, because the declaration concerned events that
    occurred after the administrative proceedings, the trial court had
    discretion to admit it as part of the writ proceedings. (See Code
    Civ. Proc., § 1094.5, subd. (e) [“[w]here the court finds that there
    is relevant evidence that, in the exercise of reasonable diligence,
    could not have been produced . . ., the court may admit the
    evidence at the hearing on the writ”].) Finally, the fact that the
    declaration did not include formal proofs of service did not render
    it inadmissible. Neither section 21167.7 nor Code of Civil
    Procedure section 388 requires the filing of a proof of service as
    part of the notification procedure. Rather, these statutes simply
    provide that a party bringing a CEQA action must “furnish” a
    copy of its pleadings to the Attorney General. (§ 21167.7; Code
    Civ. Proc., § 388.) The declaration was sufficient to show that
    this requirement was met. On this record, Appellants have
    failed to demonstrate that the trial court erred in finding that
    69
    Petitioners were entitled to attorney’s fees under Code of Civil
    Procedure section 1021.5.
    C.    Gelfand Is Personally Liable For His Portion
    Of The Attorney’s Fee Award
    Appellants assert that, even if Petitioners were entitled to
    recover their attorney’s fees, the trial court erred in finding that
    Gelfand was jointly and severally liable for half of the fee award.
    Appellants argue that Gelfand has no personal liability in this
    case because he was not the applicant or the property owner for
    the Cornerstone Mixed-Use Project, but rather acted solely in his
    representative capacity as an officer of ACR’s general partner.
    “Generally speaking, the opposing party liable for attorney
    fees under [Code of Civil Procedure] section 1021.5 has been
    the defendant person or agency sued, which is responsible for
    initiating and maintaining actions or policies that are deemed
    harmful to the public interest and that gave rise to the litigation.
    [Citations.]” (Connerly v. State Personnel 
    Bd., supra
    , 37 Cal.4th
    at pp. 1176-1177; accord, Adoption of Joshua S. (2008) 
    42 Cal. 4th 945
    , 957 [“the parties against whom attorney fees should be
    assessed should be those responsible for the policy or practice
    adjudged to be harmful to the public interest”].) The designation
    of a person or entity as a real party in interest in a litigation does
    not necessarily make that person or entity an opposing party
    within the meaning of Code of Civil Procedure section 1021.5.
    (Connerly v. State Personnel 
    Bd., supra
    , 37 Cal.4th at pp. 1180-
    1181.) Rather, opposing parties found liable for attorney’s fees
    under the statute typically are “either real parties in interest
    that [have] a direct interest in the litigation, the furtherance of
    which was generally at least partly responsible for the policy or
    70
    practice that gave rise to the litigation, or [are] codefendants
    with a direct interest intertwined with that of the principal
    defendant.” (Id. at p. 1181.) Accordingly, in the context of a
    mandamus proceeding, “a real party in interest . . . that has a
    direct interest in the litigation, more than merely an ideological
    or policy interest, and actively participates in the litigation is an
    opposing party within the meaning of Code of Civil Procedure
    section 1021.5 and can be liable for attorney fees under the
    statute.” (Mejia v. City of Los Angeles (2007) 
    156 Cal. App. 4th 151
    , 161; see also San Bernardino Valley Audubon Society, Inc.
    v. County of San Bernardino (1984) 
    155 Cal. App. 3d 738
    , 756
    [“[w]hen a private party is a real party in interest and actively
    participates in litigation along with the governmental agency, it
    is fair for that party to bear half the fees”].)
    In this case, the record demonstrates that Gelfand was a
    real party in interest who pursued a direct interest in the project
    that gave rise to the CEQA action and actively participated in the
    litigation. First, Gelfand was properly named as a real party in
    interest in the litigation. Section 21167.6.5 requires a petitioner
    in a CEQA action to name, as a real party in interest, any person
    who is identified as the applicant in the notice of determination.
    (§ 21167.6.5, subd. (a).) It is undisputed that Gelfand was listed
    as the sole applicant in the City’s Notice of Determination for its
    approval of the project and adoption of the MND.
    Second, there is substantial evidence supporting a finding
    that Gelfand had a direct interest in the project that gave rise to
    the litigation. In January 2011, a representative for ACR wrote a
    letter to the City in which he requested on Gelfand’s behalf that
    the project be placed on hold while Gelfand decided how to best
    proceed. The letter noted that Gelfand had been “the owner of
    71
    the property for the past six years,” and had “diligently been
    designing a project intended to meet the City’s objectives as set
    forth in the [AVSP].” In July 2013, Gelfand personally wrote a
    letter to the City in which he requested that the hold on the
    project be removed so that he could proceed with a formal
    application. In his letter, Gelfand identified himself as the
    “owner of the Cornerstone property,” and listed both his name
    and ACR as the applicants for the project. After voting to
    approve the project, the Planning Commission enacted three
    resolutions granting entitlements for the project, each of which
    identified Gelfand as the applicant. In approving the project, the
    City Council enacted parallel resolutions that also named
    Gelfand as the sole project applicant. In the first amended
    petition, Petitioners alleged on information and belief that
    Gelfand and ACR were the “legal and equitable owners of the
    Project Site and the Applicants for the entitlements being
    challenged in this case.” In their verified answer to the first
    amended petition, Gelfand and ACR admitted those specific
    allegations.
    Third, the evidence is sufficient to support a finding that
    Gelfand actively participated in all stages of the litigation. In
    addition to filing a verified answer, Gelfand and ACR jointly
    filed an opposition to the writ petition, objections to evidence, a
    supplemental brief on issues of exhaustion and cultural resource
    impacts, an opposition to the motion for attorney’s fees, and a
    supplemental brief on Gelfand’s personal liability for a fee award.
    Both Gelfand and ACR have appealed the underlying judgment.
    At no time before judgment was entered did Gelfand ever dispute
    his status as a project applicant or as a real party in interest.
    72
    In arguing that Gelfand cannot be personally liable for
    attorney’s fees, Appellants note that ACR is a California limited
    partnership and the sole owner of the property at issue in this
    case. Gelfand, on the other hand, is one of 27 limited partners in
    ACR, and the president of the corporation that serves as ACR’s
    sole general partner. Appellants assert that, because Gelfand
    merely acted as an officer of ACR’s general partner throughout
    the project development and approval process, he is not liable for
    any of ACR’s obligations. However, the trial court reasonably
    could have inferred from the evidence that Gelfand was not
    acting solely in a representative capacity on behalf of ACR, but
    was also holding himself out as a property owner and/or project
    applicant. As noted, Gelfand specifically was identified as the
    owner of the subject property in ACR’s correspondence to the
    City, including correspondence signed by Gelfand. Gelfand also
    was identified as the sole project applicant in the City’s notice of
    determination and various resolutions granting entitlements for
    the project. There is no indication that Gelfand ever objected to
    any of those documents or sought to correct them to name ACR
    as the proper applicant. Instead, Gelfand participated in the
    administrative process leading to the City’s approval of the
    project, and then actively litigated the merits of the CEQA action
    and the attorney’s fee motion. Considering the totality of these
    circumstances, the trial court did not err in finding that ACR
