    Plaintiffs and Appellants,                                    A162283

    Defendant and Respondent.
    In 2014, appellants Citizens for Free Speech, LLC (Citizens) and
    Michael Shaw (collectively referred to as “appellants”) entered into an
    agreement allowing Citizens to install and maintain billboards and
    supporting structures on Shaw’s land1 in an unincorporated portion of
    respondent County of Alameda (the County). It is not disputed that the
    billboards and supporting structures were installed and maintained in
    violation of the County’s Code of General Ordinances, Title 17 (“the zoning
    ordinance”).2 In 2019, the County passed a resolution that declared the
    1     After the billboards were installed, Shaw sold the land to a third party,
    but retained an easement to maintain the billboards. The new owner is not
    involved in this litigation.

    General Ordinances.
    1
    billboards and supporting structures to be a public nuisance in violation of
    the zoning ordinance and ordered their abatement by removal. Appellants
    sought to set aside the County’s resolution by filing a petition for a writ of
    mandate and complaint seeking declaratory and injunctive relief. We now
    affirm the judgment denying the writ and dismissing the complaint.
    FACTS
    I.    Background
    This appeal centers on appellants’ installation and maintenance of
    billboards with supporting structures on land in an unincorporated portion of
    the County. During the course of the underlying litigation, the billboards
    included signs with messages of “noncommercial speech, political speech, and
    both onsite and offsite commercial speech.”3
    The challenged billboards and supporting structures are subject to the
    zoning ordinance, specifically: (1) section 17.18.010 (purpose of a planned
    development district)4; (2) section 17.18.120 (land use within the boundaries
    3     At the time the billboards were constructed, the land then owned by
    Shaw also contained a self-storage business with individual lockers to
    accommodate the storage of customers’ property as well as open storage for
    customers’ recreational vehicles. There was, and remains, a sign on the land
    displaying “onsite commercial speech” concerning the self-storage business.
    That sign is not at issue on this appeal.
    4      At all relevant times, section 17.18.010 read: “Planned development
    districts, hereinafter designated as PD districts, are established to encourage
    the arrangement of a compatible variety of uses on suitable lands in such a
    manner that the resulting development will: [¶] A. Be in accord with the
    policies of the General Plan of the county; [¶] B. Provide efficient use of the
    land that includes preservation of significant open areas and natural and
    topographic landscape features with minimum alteration of natural land
    forms; [¶] C. Provide an environment that will encourage the use of common
    open areas for neighborhood or community activities and other amenities; [¶]
    2
    of a planned development district (in this case the 1833rd Zoning Unit) to
    conform to the approved land use and development plan)5; (3) section
    17.52.515, subdivision (A) (regulations of billboards in unincorporated areas
    of the County)6; and (4) Ordinance No. O-89-03 (adopted on January 5, 1989),
    further limiting the type of signage allowed to one non-electrical sign with
    maximum dimensions of two feet by twenty-four feet. “Any property found
    . . . to be maintained in violation of Title 17 is . . . a public nuisance,” and
    subject to abatement by “rehabilitation, removal, demolition, or repair.”
    (§ 17.59.010.)
    D. Be compatible with and enhance the development of the general area; [¶]
    E. Create an attractive, efficient and safe environment.”
    5      At all relevant times, section 17.18.120 read: “Any use of land within
    the boundaries of a planned development district adopted in accordance with
    the provisions of this chapter shall conform to the approved land use and
    development plan.”
    6      At the time of the 2014 installation of the billboards, section 17.52.515
    read, in pertinent part, that “[n]otwithstanding any other provision in Title
    17, no person shall install, move, alter, expand, modify, replace or otherwise
    maintain or operate any billboard or advertising sign in the unincorporated
    areas of Alameda County, except: [1.] Those billboards or advertising signs
    which legally exist as of the time this section is first adopted; [2.] Those
    billboards or advertising signs for which a valid permit has been issued and
    has not expired.” (Id., Paragraph A.) The “purpose and intent” of section
    17.52.515 was: “[¶] 1. To protect and advance the county’s interests in
    community aesthetics by the control of visual clutter, pedestrian and driver
    safety, and the protection of property values; [¶] 2. To implement the county’s
    general plan by insuring that billboards and advertising signs within the
    county’s unincorporated area are compatible with their surroundings and are
    in keeping with the goals and objectives of those plans; and [¶] 3. To maintain
    the attractiveness and orderliness of the county’s unincorporated area’s
    appearance.” (§ 17.52.515, Paragraph B.) In 2019, subsection B., paragraph
    1, was amended to add that the purpose and intent of section 17.52.515 was
    to also protect and advance the County’s interests in community aesthetics by
    the “protections of scenic corridors.” (Ord. No. 2019-2, § 2, 1-15-19.)
    3
    II.   Appellants’ First Federal Action
    On June 1, 2014, appellants filed an action in the Northern District of
    California (“first federal action”)7 seeking (1) a declaration that the County’s
    zoning ordinance violated appellants’ federal and state constitutional rights,
    and (2) a permanent injunction to enjoin the enforcement of any zoning
    ordinance sections that allowed for the removal of the billboards and
    supporting structures as a public nuisance. One day later, on June 2, a
    county code enforcement investigator conducted a site visit.
    On June 10, 2014, Shaw received a “Declaration of Public Nuisance
    – Notice to Abate dated June 2, informing him the land contained
    “unlawful signs (billboards),” in violation of zoning ordinance sections
    17.18.010 and 17.18.120 and provisions of the county general plan (“not a
    permissible use under the Resource Management land use designation”) and
    directing him to “[r]emove the billboards, including the support/
    mount, from the property” (bolded language in original) (hereinafter “the
    2014 Declaration of Public Nuisance”).
    In response to the 2014 Declaration of Public Nuisance, appellants filed
    a successful preliminary injunction motion, which temporarily stayed any
    administrative nuisance abatement proceeding pending resolution of the first
    federal action. (Citizens for Free Speech, LLC v. County of Alameda (N.D.
    Cal. 2014) 
    62 F.Supp.3d 1129
    , 1134.) However, following further
    proceedings, the federal district court found in favor of the County on all
    claims, except for one section of the zoning ordinance not at issue in this
    appeal.8 (Citizens for Free Speech, LLC v. County of Alameda (N.D. Cal.
    7     All further federal actions were filed in the Northern District of
    California.
    8     The federal district court held that “section 17.52.520(A) (a provision
    that favored signs by public officials) violated the equal protection clause, as
    4
    2015) 
    114 F.Supp.3d 952
    , 967-973, Citizens for Free Speech, LLC v. County of
    Alameda (N.D. Cal. 2016) 
    194 F.Supp.3d 968
    , 971–972; see Citizens for Free
    Speech, LLC v. County of Alameda, supra, 2017 U.S. Dist. Lexis 33322.)
    Pertinent to appellants’ arguments on appeal, the federal district court
    explicitly found that: (1) sections 17.18.010 and 17.18.120 (which formed the
    basis of the 2014 Declaration of Public Nuisance) were constitutional as
    applied to appellants’ billboards (Citizens for Free Speech, LLC v. County of
    Alameda, supra, 114 F.Supp.3d at pp. 958, 967-973); (2) section 17.52.515
    (curtailing the proliferation of billboards in unincorporated areas) was a valid
    content-neutral regulation of time, place, or manner of speech, which passed
    intermediate scrutiny analysis under both the federal and state Constitutions
    (Citizens for Free Speech, LLC v. County of Alameda, supra, 114 F.Supp.3d at
    pp. 967–973); and (3) appellants were not entitled to a permanent injunction
    barring the County from enforcing its zoning ordinance (Citizens for Free
    Speech, LLC v. County of Alameda, supra, 2017 U.S. Dist. Lexis 33322,
    supra, at p.*12).
    it was content-based and did not withstand [a] strict scrutiny [analysis]. . . .
    [After the federal district court’s ruling,] the County amended section
    17.52.520(A), removing the constitutionally flawed language,” to the
    satisfaction of that court. (Citizens for Free Speech, LLC v. County of
    Alameda (N.D. Cal. 2017) 2017 U.S. Dist. Lexis 33322 at pp.*3, 20–21, 23 &
    fn. 14.) Because appellants’ success in securing a change in the zoning
    ordinance was limited to section 17.52.520(A), and they had not otherwise
    “achieved a change in the law that justifie[d] the continued display of [the]
    billboards (Citizens for Free Speech, LLC. v. County of Alameda, supra, 2017
    U.S. Dist. Lexis 33322 at p.*12), the federal district court awarded appellants
    $1 in nominal damages and attorney fees in a reduced amount. (Id. at pp.*8,
    23-24.)
    5
    III.    The County’s Nuisance Abatement Proceeding
    Following the conclusion of the first federal action, on September 22
    and September 27, 2017, two county code enforcement officers conducted
    another site visit.
    Shaw was sent a “Declaration of Public Nuisance – Notice to
    Abate,” dated September 28, 2017, informing him that the land contained
    “[f]our unauthorized signs [hereinafter referred to as billboards],
    including support structures” and “ [o]ne unauthorized digital
    billboard, including support structures” (photographs attached), which
    violated zoning ordinance sections 17.18.20 and 17.52.515 and Ordinance No.
    O-89-03, and directed him to “[r]emove the five signs identified above,
    including support structures” (bolded language in original) (hereinafter
    “the 2017 Declaration of Public Nuisance”). If the billboards were not
    removed, the County would pursue an administrative nuisance abatement
    proceeding.
    When appellants failed to remove the billboards, the County sent Shaw
    a Notice of Administrative Hearing on Abatement of Nuisance before the
    Board of Zoning Adjustments (BZA) to determine whether the billboards
    violated the zoning ordinance and should be declared a public nuisance and
    abated by removal.
    IV.     Appellants’ Second Federal Action
    In response to the 2017 Declaration of Public Nuisance, appellants filed
    a second federal action in early February 2018.9 Appellants contended the
    County was barred from pursuing an administrative nuisance abatement
    proceeding due to the resolution of the first federal action in appellants’ favor.
    9    In this second lawsuit, appellants named as defendants the County, the
    BZA and named members of the BZA (sued in their official capacities).
    6
    According to appellants, if the County wanted to pursue an administrative
    nuisance abatement proceeding it should have filed a compulsory
    counterclaim for such relief under rule 13 of Federal Rules of Civil Procedure
    (28 U.S.C.) (“Rule 13”). In the alternative, appellants argued the first federal
    action barred any later administrative nuisance abatement proceeding under
    “long-recognized principles of res judicata.”
    On September 4, 2018, the federal district court dismissed the second
    federal action for lack of jurisdiction over appellants’ federal constitutional
    claims, invoking the doctrine set forth in Younger v. Harris (1971) 
    401 U.S. 37
     (Younger) that requires a federal court to abstain from considering federal
    claims that may interfere with ongoing state proceedings. (Citizens for Free
    Speech, LLC. v. County of Alameda (N.D. Cal. 2018) 
    338 F.Supp.3d 995
    ,
    1002–1004.) The federal district court also issued an alternate ruling finding
    that, even if Younger were inapplicable, dismissal would be required because
    the County was not barred from pursuing an administrative nuisance
    abatement proceeding under Rule 13 or the federal common law of res
    judicata or claim preclusion. (Id. at pp. 1006–1008.) The Ninth Circuit
    affirmed. (Citizens for Free Speech, LLC v. County of Alameda (9th Cir. 2020)
    
    953 F.3d 655
    , 656–658.)
    V.    Board of Zoning Adjustments (BZA) Hearing
    Following resolution of the second federal action, the County
    rescheduled the BZA hearing concerning appellants’ challenge to the 2017
    Declaration of Public Nuisance.
    On November 8, 2018, the BZA (comprised of two members) held a
    public hearing. The hearing began with the County assistant planning
    director reciting portions of the written staff report prepared by members of
    the planning department. The planning department staff concluded the
    7
    billboards and the supporting structures did not conform to the zoning
    ordinance, thereby rendering them a public nuisance and requiring
    abatement by removal. The BZA chairperson also noted that, “[p]rior to the
    meeting” being held that day, appellants had submitted a “binder” of
    documents that had been reviewed by both BZA members “for the first hour.”
    Public comment was made by Shaw, Jeffrey Herson (Citizens’
    representative), two attorneys jointly representing appellants, and the
    County’s outside counsel. One of appellants’ counsel specifically stated he
    was responsible for the late submission of appellants’ binder of documents
    and asked the BZA to consider those documents in rendering its decision.
    Counsel explained that the documents were in support of appellants’ position
    that removal of the billboards was barred as the federal district court had
    declared the zoning ordinance unconstitutional at the time of the installation
    of the billboards. In opposition, the County’s outside counsel asserted that
    the federal litigation determined that the zoning ordinance was
    constitutional, save for one section not pertinent to appellants’ billboards;
    therefore, the County could proceed with an administrative nuisance
    abatement proceeding to remove the billboards. The County’s outside counsel
    also urged the BZA to uphold the 2017 Declaration of Public Nuisance as
    appellants had not disputed the existence of the billboards and that their
    maintenance violated the zoning ordinance.
    After the public comment portion of the hearing, the BZA Chairman
    continued the hearing with a discussion between board members and county
    staff. A senior deputy county counsel stated that the only issue before the
    BZA was the validity of the 2017 Declaration of Public Nuisance, and not the
    validity of the federal district court’s decisions. In clarifying her statement,
    counsel stated: “Can I clarify one item I said? I indicated what wasn’t before
    8
    you was the lower court’s decision. I’m not saying you can’t consider and you
    should not consider all the information that was provided to you today. It’s
    just merely you’re not deciding on whether that decision should be turned
    around, the lower court’s decision. But you certainly can consider all the
    materials that were submitted, and I will ask because there has been some
    reference to time. Have both of you for purposes of the record had ample time
    to review all the information that was provided to you today?” The BZA
    chairperson confirmed he had had enough time to review the information, but
    the other board member indicated he wanted more time, stating twenty
    minutes “is fine,” and the meeting was adjourned for twenty minutes.
    When the meeting reconvened, the BZA chairperson asked if there
    were any more questions for staff. There were no further questions and no
    board member asked for additional time to review appellants’ written
    submission. The BZA members then voted and approved the staff
    recommendation, specifically declaring that Shaw’s property was in violation
    of sections 17.18.120 and 17.52.515, and Ordinance Number O-89-03, thereby
    rendering the billboards and supporting structures to be a public nuisance,
    and the billboards and supporting structures were to be removed by a certain
    date.
    On November 13, 2018, the BZA issued its written decision, declaring
    the billboards and supporting structures to be a public nuisance as they were
    being maintained in violation of the zoning ordinance, and ordering removal
    to abate the public nuisance. The BZA’s order was based on a “Pre-Hearing
    Report,” which identified “public nuisance conditions” and recommended the
    finding of “violation;” and the BZA’s consideration of “all said reports,
    recommendations and testimony,” noting that “the owner or representative
    did appear at said hearing to present testimony.”
    9
    VI.   Board of Supervisors (BOS) Hearing
    Following the BZA’s issuance of its abatement order, appellants filed
    their appeal with the BOS.
    Before the public hearing on the appeal, appellants’ counsel sent a
    letter setting forth the reasons for the appeal. Appellants asserted, in
    pertinent part, that: (1) any removal order “was waived” by the County’s
    failure to seek that relief in appellants’ earlier federal litigation that resulted
    in a final judgment in appellants’ favor; (2) during the BZA hearing county
    counsel informed the board members that they did not need to consider all
    evidence submitted at the hearing; (3) during the BZA hearing a named
    board member requested additional time to consider the matter, but county
    counsel insisted that a decision be rendered in 20 minutes; and (4) appellants
    objected generally that the procedures employed in this matter failed any
    measure of constitutionally required due process and unconstitutionally
    deprived appellants, and those on whose behalf they spoke, of their free
    speech rights under the United States Constitution and the California
    Constitution.
    On February 5, 2019, the BOS held a public hearing on appellants’
    appeal of the BZA’s abatement order. The proceeding began with the County
    assistant planning director reciting portions of the staff report prepared by
    the planning department and setting forth the recommendation that the
    appeal be denied and the BZA’s abatement order be upheld. The staff report
    specifically stated that at the BZA hearing appellants did not dispute the
    existence of the billboards or that they violated the zoning ordinance.
    Instead, appellants contended only that the billboards were permitted based
    on the prior federal litigation. In their written appeal to the BOS, appellants
    again made no denial of the factual basis for the abatement order, but argued
    10
    only that the BZA’s abatement order was not based on requirements in
    applicable statutes or the zoning ordinance.
    The County assistant planning director also informed the BOS of the
    status of the billboards and supporting structures. At the time of the BOS
    hearing, “there are two support structures that used to hold two billboards
    each, and there’s a third support structure that currently holds an intact and
    functioning digital display billboard. The four billboards previously have
    been removed. It’s just the support structures that remain.” The County
    assistant planning director also informed the BOS that appellants’ prior
    federal court litigation had resulted in the rejection of their argument that
    the County could not proceed with an administrative nuisance abatement
    proceeding.
    During the public comment portion of the hearing, the BOS heard first
    from Shaw, and then from Jeffrey Herson, Citizens’ representative. During
    their statements addressing the merits of the appeal, appellants focused their
    arguments on the purported preclusive effect of the prior federal court
    litigation.
    Appellants made no statements challenging the county staff’s report
    that the billboards and supporting structures were in violation of the zoning
    ordinance, thereby rendering them a public nuisance, or challenging the
    county staff’s recommendation that the public nuisance should be abated by
    removal of the billboards and supporting structures. The BOS voted and
    denied appellants’ appeal.
    The County later issued a written resolution, declaring the billboards
    and supporting structures to be a public nuisance and ordering abatement by
    removal. The resolution recited that appellants had appeared at the BOS
    hearing and presented testimony and argument in support of the appeal; the
    11
    current owners of record of the property had not appeared at the hearing or
    otherwise responded to the notice of the hearing; the BOS had considered a
    staff report and recommendations provided by county staff; and the BOS had
    considered “the appeal de novo.” The resolution also specifically recited that
    the BOS had found the billboards and supporting structures to be a public
    nuisance in violation of sections 17.18.120, 17.52.515, the 1833rd Zoning
    Unit, and Ordinance O-89-03, and ordered abatement by removal of the
    billboards and supporting structures.
    VII. Appellants’ Third Federal Action
    Following the issuance of the County’s resolution, appellants filed
    another federal action (“third federal action”) on February 25, 2019 that
    alleged several causes of action. The first four substantive causes of action
    sought relief based on federal and state constitutional claims for violation of
    free speech and due process. Two state law substantive causes of action
    sought a writ of administrative mandamus and a writ of prohibition pursuant
    to California Code of Civil Procedure sections 1094.5 and 1103, respectively.
    The federal district court (1) granted the County’s motion to dismiss the
    federal causes of actions without leave to amend, and (2) declined to accept
    supplemental jurisdiction of any state law claims under 28 United States
    Code section 1367, subdivision (c). (Citizens for Free Speech, LLC v. County
    of Alameda [dec. Nov. 6, 2019; case 4:19-cv-01026-SBA][nonpub. opn.].) The
    Ninth Circuit affirmed. (Citizens for Free Speech, LLC v. County of Alameda
    (9th Cir. 2020) 830 F. Appx. 551.)
    VIII. Appellants’ Current State Court Action
    Following the dismissal of the third federal action, appellants
    commenced this state court action by filing their complaint for injunctive and
    declaratory relief and petition, seeking, among other things, a writ of
    12
    mandate directing the County to set aside its resolution declaring the
    billboards a public nuisance and requiring abatement by removal.
    In resolving appellants’ petition for a writ of mandate, the trial court
    considered the pleadings, the parties’ written submissions, the
    administrative record, matters subject to judicial notice, and counsel’s
    arguments made at a hearing on February 5, 2021. The court issued a
    written order on February 13, 2021, denying the petition for a writ of
    mandate. It later entered a judgment in favor of the County that
    incorporated the February 13 order and dismissed the related complaint.
    This appeal ensued.10
    DISCUSSION
    I.    Applicable Law and Standard of Review
    We begin our discussion with a review of the applicable law and
    standard of review.
    A.     Land Use Regulation
    “ ‘Land use regulation in California historically has been a function of
    local government under the grant of police power contained in article IX,
    section 7 of the California Constitution.’ ” (Citizens for Free Speech, LLC v.
    County of Alameda, supra, 338 F.Supp.3d at p. 1007, citing Big Creek Lumber
    Co v. County of Santa Cruz (2006) 
    38 Cal.4th 1139
    , 1151 & Wilkins v. City of
    San Bernardino (1946) 
    29 Cal.2d 332
    , 337 [noting a county’s decision to
    enforce its ordinance is a matter within its discretion].) Hence, “ ‘ “[i]t is well
    10     In their notice of appeal, appellants seek review of the February 26,
    2021 judgment and the February 13, 2021 order denying their petition for a
    writ of mandate, which order was incorporated in the judgment. We dismiss
    the appeal from the February 13, 2021 order, which is not separately
    appealable, and review that order on appeal from the February 26, 2021
    judgment. (See Torres v. City of San Diego (2007) 
    154 Cal.App.4th 214
    , 222
    [“ ‘there can only be one “final judgment” in an action’ ”].)
    13
    settled that a municipality may divide land into districts and prescribe
    regulations governing the uses permitted therein, and that zoning
    ordinances, when reasonable in object and not arbitrary in operation,
    constitute a justifiable exercise of police power.” ’ ” (Hernandez v. City of
    Hanford (2007) 
    41 Cal.4th 279
    , 296.)
    “Consistent with [its police] power,” the County has enacted a
    comprehensive zoning ordinance, “which confers the power” to declare a
    violation of the zoning ordinance a public nuisance and to provide for the
    abatement of the public nuisance “through an extra-judicial, administrative
    process.” (Citizens for Free Speech, LLC v. County of Alameda, supra, 338
    F.Supp.3d at p. 1007; see Golden Gate Water Ski Club v. County of Contra
    Costa (2008) 
    165 Cal.App.4th 249
    , 255 [violations of a planning code
    constitute a public nuisance].)
    The County’s regulation of billboards does not impermissibly impinge
    on a landowner’s constitutional right to the use of the property. “There is no
    constitutional right to own property free from regulation. Neither the state
    nor the federal Constitution guarantees any person absolute liberty of action.
    [Citation.] ‘We do not consider lightly the importance of the constitutional
    guarantee attaching to private ownership of real property. [¶] However, . . . it
    was clearly established that property ownership rights, reserved to the
    individual by constitutional provision, must be subordinated to the rights of
    society. It is now a fundamental axiom in the law that one may not do with
    his property as he pleases; his use is subject to reasonable restraints to avoid
    societal detriment. . . .’ ” (Whaler’s Village Club v. California Coastal Com.
    (1985) 
    173 Cal.App.3d 240
    , 253; see E. W. A. P., Inc. v. City of Los Angeles
    (1997) 
    56 Cal.App.4th 310
    , 325 [“[a]dministrative decisions which result in
    restricting a property owner’s return on his property, increasing the cost of
    14
    doing business, or reducing profits are considered impacts on economic
    interests, rather than on fundamental vested rights”].)
    Also, the County’s regulation of billboards does not impermissibly
    impinge on a landowner’s constitutional right to free speech. It is settled that
    “[b]illboards are a well-established medium of communication use to convey a
    broad range of different kinds of messages,” “[b]ut whatever its
    communicative function, the billboard remains a ‘large, immobile, and
    permanent structure which like other structures is subject to . . . regulation.’
    [Citation.] Moreover, because it is designed to stand out and apart from its
    surroundings, the billboard creates a unique set of problems for land-use
    planning and development.” (Metromedia, Inc. v. City of San Diego (1981)
    
    453 U.S. 490
    , 501–502 (plurality opinion).)
    As the federal district court has already ruled, Alameda County’s
    zoning ordinance section 17.52.515, “curtailing” the proliferation of billboards
    in unincorporated areas of Alameda County, is a valid “ ‘content-neutral
    regulation of the time, place, or manner of speech,’ ” which passes
    “ ‘intermediate scrutiny’ ” under both the federal and California
    Constitutions. (Citizens v. Free Speech, LLC v. County of Alameda, supra,
    
    114 F.Supp.3d 952
    , 967-973; see City of Austin v. Reagan National
    Advertising of Austin, LLC (2022) __ U.S. __, 
    142 S. Ct. 1464
    , 1472-1473
    (majority opinion) [Reed v. Town of Gilbert (2015) 
    576 U.S. 155
     did not
    require application of strict scrutiny to zoning ordinance that did not single
    out any topic or subject matter on a billboard for differential treatment and
    where the billboard sign’s substantive message itself was irrelevant to
    application of the zoning ordinance].)
    15
    B.    The County’s Nuisance Abatement Procedures
    Under the County’s administrative nuisance abatement procedures, a
    property in violation of the zoning ordinance may be declared a public
    nuisance, resulting in the issuance of a notice to abate. (§§ 17.59.010,
    17.59.030.) While a property found to be a public nuisance is subject to
    abatement by “rehabilitation, removal, demolition, or repair” (§ 17.59.010),
    “[n]o property shall be found to be a public nuisance under [s]ection 17.59.010
    and ordered demolished unless there is no reasonable way other than
    demolition and removal to correct such nuisance, as determined by the
    county” (§ 17.59.150).
    If the property owner fails, neglects, or refuses to comply with a notice
    to abate, an administrative hearing will be conducted before the BZA.
    (§§ 17.59.040–17.59.060.) “At the time stated in the notice, the [BZA] shall
    hear and consider all relevant evidence, objections or protests, and shall
    receive testimony relative to such alleged public nuisance and to proposed
    rehabilitation, repair, removal or demolition of such property. [11] Said
    hearing may be continued from time to time. [¶] If the [BZA] finds that such
    public nuisance does exist and that there is sufficient cause to rehabilitate,
    11    The zoning ordinance also includes general procedural rules governing
    the BZA and BOS hearings. Section 17.50.130 specifically provides that the
    hearings “need not be conducted according to the California Code of
    Evidence;” “[h]earsay evidence may be used for the purpose of supplementing
    or explaining any direct evidence, but shall not be sufficient in itself to
    support [a] finding unless it would be admissible over objection in civil
    actions in courts of competent jurisdiction in this state;” “[a]ny relevant
    evidence shall be admitted if it is the type of evidence on which reasonable
    persons are accustomed to rely in the conduct of serious affairs, regardless of
    the existence of any common law or statutory rule which might make
    improper the admission of such evidence over objection in civil actions in
    courts of competent jurisdiction in the state;” and “[i]rrelevant and unduly
    repetitious evidence shall be excluded.”
    16
    demolish, remove or repair the nuisance, the enforcement officer shall
    prepare findings and an order for the [BZA’s] adoption, which shall specify
    the nature of the nuisance, the method[(s)] of abatement and the time within
    which the work shall be commenced and completed which shall not exceed
    sixty (60) calendar days.” (§ 17.59.060.)
    A property owner dissatisfied with the BZA’s decision may file an
    appeal to be heard before the BOS. (§ 17.59.090.) The appeal must include a
    statement of the grounds of the appeal, “together with all material facts and
    support thereof.” (§17.59.090 (D).) Upon the conclusion of the hearing, the
    BOS shall determine whether the property or any part thereof as maintained
    constitutes a public nuisance; if so, the BOS shall adopt a resolution
    declaring such property to be a public nuisance setting forth its findings and
    ordering the abatement by having such property rehabilitated, repaired, or
    demolished and removed in the manner and means specifically set forth in
    the resolution. (§ 17.59.100.)
    A ruling by the BOS is deemed final (§ 17.59.100) and may be appealed
    by way of a judicial action (§ 17.59.120). Administrative decisions are subject
    to judicial review by a petition for a writ of mandate. (Code Civ. Proc.,
    § 1094.5; see Mohilef v. Janovici (1996) 
    51 Cal.App.4th 267
    , 282–284
    (Mohilef) [reviewing administrative nuisance abatement proceeding through
    a mandate proceeding].)
    C.    Judicial Review of the County’s Resolution
    When evaluating an administrative nuisance abatement proceeding
    through a mandamus proceeding, “[a] trial court may issue a writ of
    administrative mandate where an agency has (1) acted in excess of its
    jurisdiction, (2) deprived the petitioner of a fair hearing, or (3) committed a
    prejudicial abuse of discretion. (Code Civ. Proc., § 1094.5, subd. (b).) .‘Abuse
    17
    of discretion is established if the [agency] has not proceeded in a manner
    required by law, the order or decision is not supported by the findings, or the
    findings are not supported by the evidence.’ (Ibid.)” (Mohilef, supra, 51
    Cal.App.4th at p. 305.) “Where it is claimed that the findings are not
    supported by the evidence, in cases in which the court is authorized by law to
    exercise its independent judgment on the evidence, abuse of discretion is
    established if the court determines that the findings are not supported by the
    weight of the evidence. In all other cases, abuse of discretion is established if
    the court determines that the findings are not supported by substantial
    evidence in the light of the whole record.” (Code Civ. Proc., § 1094.5,
    subd. (c).)
    Additionally, Code of Civil Procedure section 1094.5, subdivision (e),
    provides: “Where the court finds that there is relevant evidence that, in the
    exercise of reasonable diligence, could not be produced or that was improperly
    excluded at the hearing before respondent, it may enter a judgment as
    provided in subdivision (f) remanding the case to be reconsidered in the light
    of that evidence; or, in cases in which the court is authorized by law to
    exercise its independent judgment on the evidence, the court may admit the
    evidence at the hearing on the writ without remanding the case.”
    The standard of review in both the trial court and appellate court is
    well settled. “[I]f the administrative decision does not substantially affect a
    fundamental vested right, the trial court considers only whether the agency’s
    findings are supported by substantial evidence in light of the whole record.
    [Citation.] On appeal, we review the administrative decision itself (not the
    decision of the trial court) to determine if it is supported by substantial
    evidence.” (Mohilef, supra, 51 Cal.App.4th at pp. 305–306; see Bixby v.
    Pierno (1971) 
    4 Cal.3d 130
    , 143, fn. 10.) “If an administrative decision
    18
    substantially affects a fundamental vested right, the trial court must exercise
    its independent judgment in evaluating the evidence and must issue a writ of
    mandate if the agency’s findings are not supported by the weight of the
    evidence.” (Mohilef, supra, at p. 305.) We review such a trial court’s
    determination under the substantial evidence test. (Ibid.)
    II.   Analysis
    A.    No Reversal is Warranted Based on the Standard of
    Review Applied by the Trial Court
    We quickly dispose of the parties’ extensive arguments regarding the
    standard of review that was – and should have been – applied by the trial
    court in evaluating the County’s resolution as the trial court explicitly
    reviewed and relied on the undisputed facts before it in rendering its
    decision.
    In their trial court briefs, the parties asked that court to apply the
    substantial evidence standard of review in evaluating the validity of the
    County’s resolution. The court agreed with the parties, concluding as follows:
    “There was more than ample evidence in the record to support
    the County’s decision. The administrative decision-makers had to
    resolve a single factual question: whether signs existed on the property
    in violation of the County’s sign regulations The administrative record
    includes (1) testimony from County staff stating that there is a ‘digital
    display billboard’ on the Property; (2) a written staff report recounting
    a site inspection that confirmed the presence of multiple signs; (3)
    pictures of the signs; and (4) a map of the signs’ locations on the
    Property. This record firmly establishes the existence of signs in
    violation of County Code sections 17.18.120, 17.52.515, and Ordinance
    O-89-03. [¶] In any event, Petitioners do not dispute that the signs
    exist – which is, in fact, a predicate of this lawsuit – or that they violate
    the County’s sign regulations. Petitioners conceded at the hearing on
    the writ that ‘the only pertinent facts’ in the administrative
    proceedings were ‘not in dispute,’ stating ‘[t]he facts are the signs are
    present and the ordinance that the County relies on to take the signs
    19
    down indicates that the signs are illegal.’ There is nothing more for the
    Court to resolve. Undisputed evidence substantially supports the
    County’s decision.”
    In a footnote, the trial court acknowledged that appellants “obliquely
    suggested for the first time in their reply brief that they had a fundamental
    vested right to free speech,” thereby implicitly asking the court to
    independently review the County’s resolution. While the court found the
    issue was not properly before it, it ruled that “because the relevant facts are
    undisputed,” it would have reached “the same result even if the applicable
    test under Code of Civil Procedure section 1094.5 were whether the weight of
    the evidence” supports the County’s resolution.
    Hence, and simply put, the record shows the trial court was not
    concerned with the credibility of witnesses or the weight of evidence as it
    properly focused on the undisputed evidence – the existence of the billboards
    on the property and their noncompliance with the zoning ordinance. And no
    other evidence was necessary to support the County’s resolution that the
    billboards were a public nuisance requiring abatement by removal.
    Therefore, we find no merit to appellants’ arguments for reversal as this is
    not a case in which the trial court was required to examine and weigh
    appellants’ evidence or exercise its independent judgment as to the credibility
    of witness and the overall weight of the evidence. (Malibu Mountains
    Recreation, Inc. v. County of Los Angeles (1998) 
    67 Cal.App.4th 359
    , 370
    (Malibu Mountains Recreation).)
    Further, we will only reverse a judgment if an error “at the trial court
    level resulted in a miscarriage of justice to the extent that a different result
    would have been probable without the error.” (Malibu Mountains Recreation,
    supra, 67 Cal.App.4th at p. 372; see Cal. Const., art. VI, § 13; Code Civ. Proc.,
    § 475; Evid. Code, §§ 353, 354.) Here, “[t]he [trial] court’s analysis of the
    20
    entire record on the basic issues that determine the outcome of this case
    leads to the unequivocal conclusion that no different result would ensue if
    this matter were to be remanded for review under the independent judgment
    test.” (Malibu Mountains Recreation, supra, at p. 372.) The trial court made
    clear that under either standard of review (substantial evidence or
    independent judgment) the County’s resolution was sustainable given it was
    “undisputed” that the billboards violated the zoning ordinance, rendering
    them a public nuisance subject to abatement by removal. Accordingly, we see
    no reason to reverse and remand to require the trial court to repeat the
    decision it has already made.12
    B.     Appellants Have Not Shown a Violation of Their Due
    Process Right to Fair Hearings
    Appellants argue the County’s resolution should be set aside because
    their due process right to fair hearings was violated by the way the County
    conducted the BZA and BOS hearings. According to appellants, they had no
    “meaningful opportunity” to present their case and hence, there can be no
    substantial evidence to support the County’s resolution. We find appellants’
    argument unavailing.
    12     The cases cited by appellants do not support a different outcome. The
    two published cases cited merely discuss general principles governing an
    appellate court’s review of a trial court’s factual findings (In re Zeth S. (2003)
    
    31 Cal.4th 396
    , 405; Guymon v. Board of Accountancy (1976) 
    55 Cal.App.3d 1010
    , 1016), and the unpublished case (Dredd v. Los Angeles County Civ.
    Serv. Comm. (Aug. 13, 2018, B279819) [nonpub. opn.]), cannot be cited to us
    or relied upon by us (Cal. Rules of Court, rule 8.1115(a) & (b)). Indeed, we
    find it particularly troubling that while the County correctly notes in its
    responsive brief that Dredd is not citable, appellants nonetheless repeat the
    citation in their reply brief without explanation.
    21
    1.    Applicable Law and Standard of Review
    It is not disputed that the County’s nuisance abatement proceeding
    implicates a protected property interest subject to due process protection
    even though the billboards were erected in violation of the zoning ordinance.
    (Traverso v. People ex. rel. Dept. of Transportation (1993) 
    6 Cal.4th 1152
    ,
    1161.) Under these circumstances, it is well settled that while the County
    has the authority, “under [its] . . . legitimate police power, to remove and
    destroy any billboard found to be in violation” of its zoning ordinance, “notice
    and the opportunity to be heard must be provided” to the owner before it may
    act “to abate a billboard maintained in violation” of its zoning ordinance. (Id.
    at pp. 1161–1162; see Mohilef, supra, 51 Cal.App.4th at p. 286 [due process
    principles applicable to the City’s administrative nuisance abatement
    proceeding required “reasonable notice and opportunity to be heard”].)
    There is no required manner of hearing that must be afforded a
    landowner at an administrative nuisance abatement proceeding to satisfy
    due process. Generally, “ ‘the courts have recognized that boards of [zoning
    adjustments and zoning appeals] are not composed of legal experts, and often
    are not guided by such experts. Accordingly, board hearings have been
    measured by less exacting standards than are applied to judicial tribunals.
    The courts have indorsed, or at least they have not disapproved, a degree of
    informality which is uncommon even to hearings conducted by administrative
    agencies . . . . [¶] In general, judicial attention is focused upon the question
    whether the hearing was basically fair. If the board . . . in its conduct of the
    hearing allowed all persons who desired to speak an opportunity to do so, and
    afforded each side a fair chance to articulate his point of view, reversal for
    failure to hold a fair hearing is unlikely.’ ” (Mohilef, supra, 51 Cal.App.4th at
    pp. 295–296.)
    22
    It has therefore been held that due process at an administrative
    nuisance abatement proceeding does not necessarily require (1) a formal
    hearing, with rights of confrontation and cross-examination of witnesses; (2)
    sworn testimony or documents made under penalty of perjury; or (3) strict
    compliance with rules of procedure and evidence necessary in a judicial
    proceeding. (See Mohilef, supra, 51 Cal.App.4th at pp. 286, 289, 292, 298–
    299; see, e.g., E. W. A. P., Inc. v. City of Los Angeles, supra, 56 Cal.App.4th at
    pp. 315–316m 324 [at an administrative nuisance abatement proceeding,
    appellant was not denied a fair hearing by “virtue of the lack of sworn
    testimony, the lack of cross-examination, or the quality of the evidence”];
    Carmel Valley View, Ltd. v. Board of Supervisors (1976) 
    58 Cal.App.3d 817
    ,
    823 [“a presentation to an administrative agency may properly include
    evidence that would not be admissible in a court of law”].)
    We review de novo appellants’ arguments that they did not receive fair
    hearings before the BZA and BOS. (Clark v. City of Hermosa Beach (1996) 
    48 Cal.App.4th 1152
    , 1169–1170 [standard of review].)
    2.    Analysis
    Appellants do not dispute they received notice of the zoning ordinance
    violations and had the opportunity for hearings before the BZA and BOS. In
    their complaint and petition, appellants confirm they “appeared” and
    “submitted evidence and testimony” at the BZA hearing, and that the BOS
    held a hearing on their appeal. They contend, however, that their due
    process rights were prejudicially violated by the manner in which the County
    conducted the hearings. We disagree, and now review their various
    contentions.
    Regarding the BZA hearing, appellants complain that “the County
    presented no witnesses,” and relied solely on “its own staff report;” appellants
    23
    “presented a binder full of evidence and documents for consideration, which
    the BZA flatly refused to consider;” and appellants were “only allowed . . .
    public comment time, and nothing more.”
    However, a review of the BZA hearing transcript reflects that
    appellants and their counsel were given the opportunity to present their
    arguments without any time limitation and the BZA members reviewed
    appellants’ binder of documents. At no time did appellants or their counsel
    state that they needed more time to present arguments or evidence. Nor did
    appellants or their counsel make any objection on the bases that the staff
    report was insufficient to support the 2017 Declaration of Public Nuisance;
    that the county staff report was not authenticated, not based on personal
    knowledge, and not made under penalty of perjury; or that the County had
    not produced either the authors of the county staff report or other witnesses
    to provide testimony and submit to cross-examination. While appellants
    received the county staff report on the day of the hearing, we see nothing in
    the record that precluded them from asking for a recess or continuance of the
    hearing to review the county staff report or call as witnesses county staff who
    prepared the staff report. (§ 17.59.060 [the BZA hearing “may be continued
    from time to time”].) Accordingly, we find appellants’ complaints about the
    BZA hearing are either not preserved for review or not supported by the
    record.
    Appellants also argue that they were not afforded due process at both
    the BZA and BOS hearings based on an evaluation of factors enunciated in
    People v. Ramirez (1979) 
    25 Cal.3d 260
     (Ramirez).) In Ramirez, our Supreme
    Court explained that “[the] identification of the dictates of due process
    generally requires consideration of (1) the private interest that will be
    affected by the official action, (2) the risk of an erroneous deprivation of such
    24
    interest through the procedures used, and the probable value, if any, of
    additional or substitute procedural safeguards, (3) the dignitary interest in
    informing individuals of the nature, grounds, and consequences of the action
    and in enabling them to present their side of the story before a responsible
    governmental official, and (4) the governmental interest, including the
    function involved and the fiscal and administrative burdens that the
    additional or substitute procedural requirements would entail.” (Id. at p.
    269.) Having independently reviewed those factors, we see no merit to
    appellants’ claim of a due process violation for the reasons stated by the trial
    court as follows:
    “. . . [T]he sole issue relevant to the County’s abatement order
    was whether [appellants’ billboards] violated the County’s ordinances.
    That fact is undisputed. When the Court questioned [appellants] at
    oral argument about what additional evidence they would have
    presented, if given the opportunity, they could not identify any and
    agreed that their [billboards] were unlawful. The probable value of
    additional or substitute procedural safeguards is therefore zero. This
    factor weighs overwhelmingly in favor of the County.
    “The remaining Ramirez factors do not alter the balance. Neither
    party disputes that [appellants] have a property interest in the
    [billboards] that requires some procedural safeguards before the
    County could have issued the abatement order. But the County
    afforded [appellants] two opportunities before the BZA and the BOS to
    present and make their case. The Court also recognizes the County’s
    important interest in using informal procedures for these types of
    [proceedings]. (Mohilef, supra, 51 Cal.App.4th at p. 294.) In light of
    the undisputed evidence that the [billboards] were unlawful,
    [appellants’] interest was adequately protected. The burden on the
    County of using more formal procedures also far outweighs the value of
    any additional process.”
    Regarding the BOS hearing, appellants complain that they were not
    allowed “to present any evidence, testimony, or substantive arguments,” and
    25
    were given “a total of two minutes” of public comment time and then cut off.
    Again, a review of the BOS hearing transcript reflects that both Shaw and
    Citizens’ representative were given an opportunity to present substantive
    arguments in support of the appeal of the BZA’s abatement order. While
    appellants contend that a supervisor impermissibly cut short Shaw’s planned
    presentation, appellants made no showing either in the trial court, or now on
    appeal, that the supervisor’s conduct resulted in relevant evidence being
    “improperly excluded at the hearing,” requiring a new hearing as allowed
    under subdivision (e) of section 1094.5 of the Code of Civil Procedure.
    Accordingly, we find appellants’ complaints about the BOS hearing to be
    unavailing.
    Appellants further contend that their due process right to a fair
    hearing on their appeal before the BOS “went to zero” after Shaw expressed
    his intent to put up political messages on the billboard signs concerning the
    ABAG [Association of Bay Area Governments], an organization opposed by
    Shaw. In response, a supervisor, who was also a county representative
    member of the ABAG, took Shaw’s comment as a threat that Shaw was going
    to put up signs against the supervisor. According to appellants, as a result of
    the exchange between Shaw and the supervisor, the supervisor “prematurely”
    ended appellants’ presentation of evidence because the supervisor felt
    “personally threatened” by appellants’ “freedom of expression through their
    billboards.”
    Appellants also contend the supervisor “expressed his inability to be
    impartial and then attempted to maintain his right to vote on the [appeal] by
    stating, ‘No, I feel like I can be impartial.’ ” For the reasons we now explain,
    we find appellants’ arguments unavailing.
    26
    As a preliminary matter, appellants have forfeited any claim of the
    supervisor’s lack of impartiality as the record does not reflect appellants
    requested that the supervisor not participate in the decision on the appeal
    after the supervisor stated he felt personally threatened by Shaw’s
    comments. (See Hayward v. Superior Court (2016) 
    2 Cal.App.5th 10
    , 49
    [“parties can waive disqualification of [decision-maker] by their conduct
    where they are aware of grounds for disqualification but continue to
    participate in the proceedings without raising the objection”].)
    In their reply brief, appellants argue that forfeiture should not apply
    because they did not have an opportunity to present their claim of the
    supervisor’s lack of impartiality during the BOS hearing. We disagree. The
    record reflects that after the described exchange between Shaw and the
    supervisor, Shaw was allowed to continue to address the BOS but he made no
    request that the supervisor not participate in the decision on the appeal
    based on the supervisor’s remarks. Similarly, although Citizens’
    representative (who spoke after Shaw) had the opportunity to do so, he also
    made no request that the supervisor not participate in the decision on the
    appeal based on the supervisor’s remarks.
    The record also does not reflect that appellants’ presentation of their
    appeal was impermissibly cut short by the supervisor. (See Liteky v. United
    States (1994) 
    510 U.S. 540
    , 556 [“[a] [decision-maker’s] ordinary efforts at
    [hearing] administration – even a stern and short-tempered [decision-
    maker]’s ordinary efforts at [hearing] administration – remain immune” from
    a claim of bias].) As the County correctly asserts, the record reflects that
    before the supervisor made his challenged remarks, Shaw had been given
    time to make a substantive argument in support of the appeal (covering three
    pages of the hearing transcript), with the supervisor later noting that Shaw
    27
    had probably been given seven minutes even though there was a three-
    minute time frame for speakers. Also, after Shaw’s presentation, Citizens’
    representative was given time to present a substantive argument in support
    of the appeal, with no complaint that the time granted him was insufficient to
    complete his presentation.
    We also see no merit to appellants’ complaint that a new hearing before
    the BOS is required because the supervisor expressed his inability to be
    impartial. As the County correctly asserts, the record reflects that after
    Citizens’ representative completed his presentation, the supervisor
    immediately asked county counsel’s advice concerning how the supervisor
    should respond to Shaw’s comments about his intent to reestablish billboard
    signs concerning the ABAG. When county counsel asked if the supervisor felt
    he could not be impartial in deciding the appeal, the supervisor confirmed
    that he felt he could be impartial but asked counsel for advice on the separate
    issue as to how to respond to Shaw’s comments that the supervisor viewed as
    a threat to a vote in a public forum. County counsel responded that the
    supervisor could vote on the appeal, and then address any response to Shaw’s
    comments after the decision on the appeal. Accordingly, we reject appellants’
    claim of error.
    When viewed in the context of the entirety of the reported BOS
    hearing, we conclude the supervisor’s challenged remarks do not reveal “such
    a high degree of . . . antagonism as to make fair judgment impossible” on the
    part of the supervisor. (Liteky v. United States, 
    supra,
     510 U.S. at p. 555.)
    The BOS was tasked with deciding whether the billboards and supporting
    structures were in violation of the zoning ordinance. The only evidence
    relevant to that decision, as conceded by appellants, was the undisputed
    evidence of the existence of the billboards and supporting structures and that
    28
    their maintenance violated the zoning ordinance. Any evidence or comments
    concerning Shaw’s proposed intent to reestablish the political content of the
    billboard signs was “irrelevant” evidence subject to exclusion. (§ 17.59.130
    [“[i]rrelevant” evidence “shall be excluded” at the hearing before the BOS].)
    Given these circumstances, we see no reason to remand and reverse for a new
    BOS hearing based on the supervisor’s challenged remarks.
    In sum, the record demonstrates appellants’ due process rights were
    satisfied as they had notice of the violations of the zoning ordinance that
    required removal of the billboards and a sufficient opportunity at each
    hearing (one before the BZA and one before the BOS) to respond, in writing
    and in person, as to why the billboards were not subject to removal as a
    public nuisance. Appellants have not shown how any additional process at
    the BZA or BOS hearings would have made any difference in the County’s
    resolution. Nor do we see any reason to reverse and remand for a new
    hearing before the BOS based on Shaw’s claim of purported bias of a
    supervisor.
    C.   No Reversal is Required Based on the County’s
    Purported Failure to Comply with Sections 17.59.130
    and 17.59.150
    Appellants contend that, separate from their due process argument,
    reversal and remand is required because the BZA and BOS hearings were not
    conducted in accordance with sections 17.59.130 (“Procedure-Hearing before
    board of zoning adjustments and Board of Supervisors” concerning the
    admission of evidence) and 17.59.150 (“Powers of abatement,” providing that
    the County is to consider reasonable alternatives to removal or demolition of
    public nuisance). According to appellants, the County’s failure to follow their
    29
    own statutory procedures renders the County’s resolution “unauthorized and
    void per se.”
    However, appellants are generally limited to raising claims of error
    that were presented in the trial court. (See Newton v. Clemons (2003) 
    110 Cal.App.4th 1
    , 11 [“ ‘[g]enerally, issues raised for the first time on appeal
    which were not litigated in the trial court are waived’ ”].) Here, the record
    reflects that in their writ petition and supporting trial memoranda appellants
    did not seek to set aside the County’s resolution on the basis that the County
    failed to comply with sections 17.59.130 and 17.59.150. Nor do appellants’
    citations to the administrative record demonstrate that the claim of error
    based on sections 17.59.130 and 17.59.150 was raised in the trial court.
    Further, appellants’ reply brief does not address the issue of forfeiture
    despite the County’s argument that the claim of error based on sections
    17.59.130 and 17.59.150 was not raised in the trial court. Even more
    significantly, appellants cite no decisional authority in support of their
    argument that the County’s purported noncompliance with the cited sections
    renders the County’s resolution “unauthorized and void per se.” Accordingly,
    we do not further address this issue. (See Bank of America, N.A. v. Roberts
    (2013) 
    217 Cal.App.4th 1386
    , 1399 [“[w]here a point lacks adequate . . .
    citation to authority, we may treat it as abandoned”].)
    D.    The County’s Administrative Nuisance Abatement
    Proceeding Was Not Barred by Rule 13, Code of Civil
    Procedure Section 426.30, or Federal or State
    Common Law Res Judicata or Claim Preclusion13
    13    At the hearing on the writ petition, appellants’ counsel argued “the
    claim preclusion issue is not even ripe” for review and “res judicata” was not
    30
    We review de novo14 and conclude that, despite appellants’ arguments
    to the contrary, the County’s administrative nuisance abatement proceeding
    was not barred by Rule 1315, Code of Civil Procedure section 426.30,16 or
    federal or state common law res judicata or claim preclusion.
    “really pertinent” because the County had not yet filed a court action seeking
    to enforce its resolution ordering abatement of the public nuisance by
    removal of the billboards. However, we agree with the trial court that given
    the multiple judicial decisions on the issues – as well as the County’s
    resolution, declaring the billboards a public nuisance, and expressly ordering
    their abatement by removal, the issue of the preclusive effect of the federal
    litigation on the County’s ability to later pursue an administrative nuisance
    abatement proceeding was “framed with sufficient definiteness to enable [us]
    to make a decree finally disposing of the controversy.” (Pacific Legal
    Foundation v. California Coastal Com. (1982) 
    33 Cal.3d 158
    , 170.)
    14     Because appellants’ contentions present questions of federal and state
    law that we review de novo (See Guerrero v. Department of Corrections and
    Rehabilitation (2018) 
    28 Cal.App.5th 1091
    , 1100-1102 & Association of
    Irritated Residents v. Department of Conservation (2017) 
    11 Cal.App.5th 1202
    , 1218 [standard of review of federal and state law claims]), we do not
    separately address appellants’ challenges to the trial court’s rulings on the
    applicability of Rule 13 and federal common law res judicata or claim
    preclusion.
    15     Rule 13 reads: “A pleading shall state as a counterclaim any claim
    which at the time of serving the pleading the pleader has against any
    opposing party, if it arises out of the transaction or occurrence that is the
    subject matter of the opposing party’s claim and does not require for its
    adjudication the presence of third parties over whom the court cannot acquire
    jurisdiction. But the pleader need not state the claim if (1) at the time the
    action was commenced the claim was the subject of another pending action,
    or (2) the opposing party brought suit upon the claim by attachment or other
    process by which the court did not acquire jurisdiction to render a personal
    judgment on that claim, and the pleader is not stating any counterclaim
    under this Rule 13.”
    16    Our parallel provision to Rule 13 is set forth in Code of Civil Procedure
    section 426.30, which reads, in pertinent part: “(a) . . . [I]f a party against
    31
    We see no merit to appellants’ contentions that the County’s
    administrative nuisance abatement proceeding was barred by Rule 13 and
    federal common law res judicata or claim preclusion, which arguments were
    presented and addressed in the federal district court’s decision dismissing the
    second federal action for failure to state a cause of action.17
    In rejecting appellants’ contention based on Rule 13, the federal district
    court persuasively stated, in pertinent part, as follows:
    “As an initial matter, . . . the County had no obligation to file a
    counterclaim in the [first federal action under Rule 13]. An ordinance
    is presumed constitutional, unless and until the plaintiff demonstrates
    otherwise. [Citation.] . . . [G]iven that [appellants] had affirmatively
    challenged the constitutionality of the Zoning Ordinance, it would have
    been superfluous for the County to file a counterclaim to establish the
    opposite – and by extension, its enforceability. [Citations.] . . . [¶] . . .
    [¶] [Appellants] also have failed to demonstrate that the Rule 13(a)
    bar, even if germane, applies to the circumstances presented. [Rule 13]
    applies where a party asserts a claim in a second federal court action
    that should have been asserted as a counterclaim in an earlier action.
    [Citation.] Here, the County is not asserting a second federal action
    against [appellants]. Rather, the County simply has resumed a local
    administrative enforcement proceeding pertaining to [appellants’
    whom a complaint has been filed and served fails to allege in a cross-
    complaint any related cause of action which (at the time of serving his
    answer to the complaint) he has against the plaintiff, such party may not
    thereafter in any other action assert against the plaintiff the related cause of
    action not pleaded.”
    17      The federal district court’s rulings, which we find persuasive and
    dispositive, are not mere dictum. In dismissing the second federal action, the
    federal district court gave two independent reasons for dismissing the action,
    namely Younger abstention and failure to state a cause of action. (Citizens
    for Free Speech, LLC v. County of Alameda, supra, 338 F.Supp.3d at
    pp. 1002–1004, 1006–1008.) “ ‘[W]here two independent reasons are given for
    a decision, neither one is to be considered mere dictum, since there is no more
    reason for calling one ground the real basis of the decision than the other.
    The ruling on both grounds is the judgment of the court and is of equal
    validity.’ ” (Southern Cal. Chapter of Associated Builders etc. Com. v.
    California Apprenticeship Council (1992) 
    4 Cal.4th 422
    , 431, fn. 3.)
    32
    billboards]. Such a proceeding is not an ‘action.’ [Citations.] Tellingly,
    [appellants] have not cited – nor has the Court been able to locate – any
    authority holding that the preclusive effective of Rule 13(a) extends to
    bar ongoing state administrative proceedings.” (Citizens for Free
    Speech, LLC v. County of Alameda, supra, 338 F.Supp.3d at pp. 1006–
    1008.)
    In specifically rejecting appellants’ argument based on federal common-
    law res judicata or claim preclusion, the federal district court persuasively
    stated, in pertinent part, as follows:
    “Separate from Rule 13(a),” appellants argue that “ ‘[t]he
    County’s Abatement claim is barred by the doctrine of claim preclusion’
    on the ground that such claim[ ] ‘could have been asserted in the [first
    federal action] in the form of counterclaim, but was not.’ [Citation.]
    ‘Res judicata, also known as claim preclusion, bars litigation in a
    subsequent action of any claims that were raised or could have been
    raised in the prior action.’ [Citation.] However, this doctrine is
    inapplicable, as the County is not seeking to relitigate any claims
    against [appellants] in this or any other court. [Citation.] [¶]
    [Appellants] concede that there is no authority applying res judicata to
    bar a subsequent administrative proceeding. Nonetheless, they point
    out that the opposite may be true; that is, an administrative action may
    in some circumstances preclude a subsequent lawsuit. [Citation.]
    [Appellants] posit that since an administrative action litigated to
    finality can preclude a subsequent court action, ‘it stands to reason that
    a court action can bar a subsequent administrative proceeding.’
    [Citation.] The Court disagrees. [¶] Res judicata only bars a second
    action. [Citation.] As noted, the County’s administrative abatement
    proceeding is not an ‘action.’ [Citation.] . . . The Court finds no merit to
    [appellants’] claim that the doctrine of claim preclusion bars the
    County from enforcing the Zoning Ordinance against [appellants] with
    respect to the [billboards].” (Citizens for Free Speech, LLC v. County of
    Alameda, supra, 338 F.Supp.3d at p. 1008.)
    We likewise see no merit to appellants’ argument that the County’s
    administrative nuisance abatement proceeding was barred under Code of
    Civil Procedure section 426.30, which is our parallel provision to Rule 13.
    According to appellants, “[t]hough based on similar legal principles,” a
    33
    finding that Rule 13 does not apply is not a finding that Code of Civil
    Procedure Section 426.30 is not applicable. However, like Rule 13, Code of
    Civil Procedure section 426.30 applies only to preclude a multiplicity of
    litigation between the parties. Here, the County has not asserted a state
    action against appellants. The County has only issued its resolution
    declaring the billboards a public nuisance and ordering their removal.
    Because the administrative proceeding is not an “ ‘action’ ” (City of Oakland
    v. Public Employees’ Retirement System (2002) 
    95 Cal.App.4th 29
    , 48), Code
    of Civil Procedure section 426.30 is not implicated here. The cases cited by
    appellants do not support a different outcome.
    We also find unavailing appellants’ arguments that the County’s
    administrative nuisance abatement proceeding was barred based on state
    common law principles of res judicata or claim preclusion. In California,
    “ ‘[a]s generally understood, “[t]he doctrine of res judicata gives certain
    conclusive effect to a former judgment in subsequent litigation involving the
    same controversy.” [Citation.] The doctrine “has a double aspect.”
    [Citation.] “In its primary aspect,” commonly known as claim preclusion, it
    “operates as a bar to the maintenance of a second suit between the same
    parties on the same cause of action. [Citation.]” [Citation.] “In its secondary
    aspect,” commonly known as collateral estoppel, “[t]he prior judgment . . .
    ‘operates’ ” in “a second suit . . . based on a different cause of action . . . ‘as an
    estoppel or conclusive adjudication as to such issues in the second action as
    were actually litigated and determined in the first action.’ [Citation.]”
    [Citation.] “The prerequisite elements for applying the doctrine to either an
    entire cause of action or one or more issues are the same: (1) A claim or issue
    raised in the present action is identical to a claim or issue litigated in a prior
    proceeding; (2) the prior proceeding resulted in a final judgment on the
    34
    merits; and (3) the party against whom the doctrine is being asserted was a
    party or in privity with a party to the prior proceeding. [Citations.]” ’
    [Citation.]” (Boeken v. Phillip Morris USA, Inc. (2010) 
    48 Cal.4th 788
    , 797
    (Boeken).)
    “Here, we are concerned with the claim preclusion aspect of res
    judicata. To determine whether two proceedings involve identical causes of
    action for purposes of claim preclusion, California courts have ‘consistently
    applied the “primary rights” theory.’ [Citation.] Under this theory, ‘[a] cause
    of action . . . arises out of an antecedent primary right and corresponding
    duty and the delict or breach of such primary right and duty by the person on
    whom the duty rests. “Of these elements, the primary right and duty and
    delict or wrong combined constitute the cause of action in the legal sense of
    the term. . . .” ’ [Citation.]” (Boeken, supra, 48 Cal.4th at pp. 797–798.)
    We find instructive the case of Maldonado v. Harris (9th Cir. 2004) 
    370 F.3d 945
    , 953 (Maldonado), decided under state common law res judicata or
    claim preclusion. In Maldonado, the State of California sought to enforce its
    law governing a landowner’s maintenance of billboards for advertising under
    a nuisance theory. (370 F.3d at p. 949.) In response, the landowner asserted
    several defenses, none of which concerned the constitutionality of the law.
    (Ibid.) The state court enjoined the landowner from maintaining the
    billboards for advertising. (Ibid.) Thereafter, the landowner filed a federal
    lawsuit, alleging the California law prohibiting billboard advertising violated
    his First Amendment rights under the United States Constitution. (Ibid.)
    The State sought to dismiss the federal action based on res judicata. (Ibid.)
    The Ninth Circuit, applying California law’s primary rights doctrine, allowed
    the landowner’s federal action to proceed, finding that the landowner’s
    federal claim was based on his primary First Amendment right to advertise
    35
    on his billboards, whereas “[t]he primary right in the state nuisance action
    was not [the owner’s] right to advertise on his billboard, but the right of the
    people of California to be free from obtrusive advertising displays along major
    highways,” which itself was based on a California statute. (Id. at p. 952.)
    Because the “primary rights involved in the two suits [were] different, the
    causes of action [were] also different” and res judicata was inapplicable to the
    owner’s federal action. (Ibid.)
    While Maldonado presents the converse of the situation before us (state
    action followed by a federal action), we find its analysis both persuasive and
    applicable to appellants’ argument that the County was barred from pursuing
    an administrative nuisance abatement proceeding following appellants’ first
    federal action. Appellants’ first federal action was based on their primary
    right to maintain the billboards to display signs under their First
    Amendment right to free speech, whereas the primary right in the County’s
    administrative nuisance abatement proceeding was the right of the people of
    the County to be free of billboards that constituted a public nuisance under
    the zoning ordinance. Because the primary rights involved in appellants’
    first federal action and the County’s administrative nuisance abatement
    proceeding are different, the County is not barred from pursuing an
    administrative nuisance abatement proceeding by state common law res
    judicata or claim preclusion.
    E.    No Reversal is Required Based on County’s Purported
    Failure to Protect Appellants’ First Amendment
    Rights
    1.     Relevant Facts
    In its written order denying the writ petition, the trial court rejected
    appellants’ First Amendment arguments, as follows:
    36
    “[Appellants] asserted claims for violation of their free speech
    rights in their petition and opening brief. Before the County filed its
    opposition brief, the Ninth Circuit held that [appellants’] identical free
    speech claims asserted in [their third federal action] in federal district
    court were precluded by [their first federal action]. [(Citizens for Free
    Speech, LLC v. County of Alameda, supra, 830 Fed. Appx. at p. 552
    [‘[t]he nuisance abatement procedures are predicated on the same
    Zoning Ordinance provisions challenged in [the first federal action].
    [Appellants’] claims therefore “were raised or could have been raised in
    the prior action” ’].)] [Appellants] did not address their First
    Amendment claims on reply and then expressly abandoned them at the
    hearing on the writ [petition].”
    2.    Analysis
    In challenging the trial court’s ruling on its First Amendment
    arguments, appellants argue the court “failed to consider the very serious
    Constitutional protections that are owed to [appellants].” According to
    appellants, the County’s administrative nuisance abatement procedures fail
    to provide necessary safeguards “to preserve free speech rights.”
    Preliminarily, we conclude this issue is not properly before us. As
    noted by the trial court and reflected in the record, appellants unambiguously
    abandoned any substantive First Amendment arguments at the hearing on
    their writ petition. In their appellate briefs appellants do not explain why we
    should now address this abandoned issue on the merits. (See People v. Catlin
    (2001) 
    26 Cal.4th 81
    , 168 [“the claim was abandoned at the trial level and is
    waived on appeal”]; Johanson Transportation Service v. Rich Pik’d Rite Inc.
    (1985) 
    164 Cal.App.3d 583
    , 588 [“issues raised and then abandoned in the
    trial court . . . cannot be considered on appeal”].)
    In any event, we agree with the County that appellants’ First
    Amendment arguments challenging the County’s administrative nuisance
    abatement procedures are barred by the doctrine of res judicata (either claim
    or issue preclusion) as the arguments “were raised or could have been raised”
    37
    in appellants’ first federal action as explained by the Ninth Circuit in its
    decision dismissing appellants’ third federal action. (Citizens for Free Speech,
    LLC v. County of Alameda, supra, 830 Fed. Appx. at p. 552.)
    THE COUNTY’S MOTION FOR MONETARY SANCTIONS ON APPEAL
    The County has filed a motion for sanctions against appellants for the
    filing of a frivolous appeal. Code of Civil Procedure section 907 provides that
    “[w]hen it appears to the reviewing court that the appeal was frivolous or
    taken solely for delay, it may add to the costs on appeal such damages as may
    be just.” Similarly, California Rules of Court, rule 8.276(a), provides that an
    appellate court has the authority to “impose sanctions . . . on a party or any
    attorney for: [¶] Taking a frivolous appeal or appealing solely to cause
    delay. . . . ” The appeal before us comes perilously close to sanctionable
    conduct as almost all the arguments “are not supported by a careful reading
    of the record or the law nor could these arguments be reasonably
    characterized as presenting unique issues or arguing for extension,
    modification, or reversal of existing law.” (Kleveland v. Siegel & Wolensky,
    LLP (2013) 
    215 Cal.App.4th 534
    , 557.)
    By compelling us to examine those arguments for which there is no
    factual or relevant legal support, appellants have caused a “useless diversion
    of this court’s attention” from “[o]ther appellate parties, many of whom wait
    years for a resolution of bona fide disputes.” (Finnie v. Town of Tiburon
    (1988) 
    199 Cal.App.3d 1
    , 17.) Nonetheless, our Supreme Court has informed
    us that we should hold that an appeal is “frivolous only when it is presented
    for an improper motive – to harass the respondent or delay the effect of an
    adverse judgment – or when it undisputedly has no merit – when any
    reasonable attorney would agree that the appeal is totally and completely
    without merit. [Citation.] [¶] . . . [T]he punishment should be used most
    38
    sparingly to deter only the most egregious conduct.” (In re Marriage of
    Flaherty (1982) 
    31 Cal.3d 637
    , 650–651.)
    Given these demanding requirements and the federal court’s decision to
    dismiss appellants’ state claims without prejudice to litigating the issues in
    state court, we cannot conclude the appeal is so totally and completely
    without all arguable merit as to justify an award of sanctions under the
    circumstances.
    DISPOSITION
    The appeal from the February 13, 2021 order is dismissed. The
    February 26, 2021 judgment is affirmed. Respondent County of Alameda is
    awarded costs on appeal.
    Respondent County of Alameda’s motion for sanctions is denied.
