    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Respondent/Defendant-Appellee/Appellee-Cross-Appellant State of
    Hawai#i, Board of Land and Natural Resources (the BLNR), must
    consider the historical evidence of the upper reaches of the wash
    of the waves.     The BLNR’s May 21, 2010 “Amended Findings of Fact,
    Conclusions of Law, and Decision and Order” (Amended Decision),
    establishing a certified shoreline for the property owned by
    Respondent/Defendant-Appellees/Appellants-Cross-Appellee Craig
    Dobbin (Dobbin) and surveyed by Respondent/Defendant-
    Appellees/Appellants-Cross-Appellee Wagner Engineering Services,
    Inc. (Wagner) located in Wainiha, Kauai (the property),
    effectively failed to do so and contained errors of law and
    clearly erroneous findings of fact.         Accordingly, the BLNR’s
    Amended Decision is vacated.        Correspondingly, the October 3,
    2012 Judgment of the Intermediate Court of Appeals (ICA)2,
    upholding the Amended Decision and vacating the March 31, 2011
    Judgment of the Circuit Court of the Fifth Circuit (the court)3
    that had sustained the appeal of Petitioners/Plaintiffs-

    § 205A-42 Determination of the shoreline. The board of
    land and natural resources shall adopt rules pursuant to
    chapter 91 prescribing procedures for determining a
    shoreline and appeals of a shoreline determinations;
    provided that no determination of a shoreline shall be valid
    for a period longer than twelve months, except where the
    shoreline is fixed by man-made structures which have been
    approved by appropriate government agencies and for which
    engineering drawings exist to locate the interface between
    the shoreline and the structure.

    Appellants/Appellees-Cross-Appellees Caren Diamond and Beau Blair
    (Petitioners) as against the said BLNR Amended Decision, is also
    vacated.    For the reasons stated herein we vacate the court’s
    March 31, 2011 Judgment in part.          We remand to the court, with
    instructions to remand the case to the BLNR for proceedings
    consistent with this opinion.
    I.
    A.
    The Shoreline Certification Process
    In 1986, the legislature enacted Act 258, which amended
    HRS chapter 205A, governing coastal zones.          1986 Haw. Sess. Laws
    Act 258, § 1 at 466-68.       As part of Act 258, the legislature
    amended the definition of “shoreline” found in HRS § 205A-1
    (Supp. 2005) to read as follows: “‘Shoreline’ means the upper
    reaches of the wash of the waves, other than storm or tidal
    waves, at high tide during the season of the year in which the
    highest wash of the waves occurs, usually evidenced by the edge
    of the vegetation growth, or the upper limit of debris left by
    the wash of the waves.”4      1986 Haw. Sess. Laws Act 258, § 2 at
    469 (emphasis in original).       That section also defines “shoreline
    area” as “all of the land area between the shoreline and the
    4
    This amendment is consistent with this court’s decision in County
    of Hawai#i v. Sotomura, 
    55 Haw. 176
    , 182, 
    517 P.2d 57
    , 62 (1973), discussed
    infra. Sotomura clarified the definition of “shoreline” in HRS § 205A-1 for
    purposes of a shoreline certification, holding that, “as a matter of law . . .
    where the wash of the waves is marked by both a debris line and a vegetation
    line lying further mauka[], the presumption is that the upper reaches of the
    wash of the waves over the course of a year lies along the line marking the
    edge of the vegetation 
    growth.” 55 Haw. at 182
    , 517 P.2d at 62 (emphases
    added).

    shoreline setback line . . . .”       HRS § 205A-41 (2001 Repl.).          The
    “shoreline setback line” is “that line established in [HRS
    Chapter 250, Part III] or by the county running inland from the
    shoreline at a horizontal plane.”        
    Id. HRS §
    205A-42 authorizes the BLNR to “adopt rules
    pursuant to chapter 91 prescribing procedures for determining a
    shoreline and appeals of shoreline determinations[.]”              Pursuant
    to this statutory mandate, the BLNR adopted, inter alia, Hawai#i
    Administrative Rules (HAR) § 13-222-10 (2003)5, setting forth the
    procedure for shoreline certification, and HAR § 13-222-26
    (2003)6, describing the process for appealing a shoreline
    5
    HAR § 13-222-10 provides, in relevant part:
    § 13-222-10   Review, revision and certification.
    (a)   The state land surveyor shall review the map,
    using the photographs, other documents and information
    provided by the applicant, and the state land
    surveyor’s knowledge of the affected area to determine
    the shoreline.
    . . . .
    (d)   When satisfied with the location of the
    shoreline, the state land surveyor shall transmit the
    shoreline maps to the chairperson [of the BLNR] for
    his approval and signature.
    (e)   This map shall be the proposed shoreline
    certification. The public notice of this proposed
    shoreline certification shall be made in accordance
    with section 13-222-12.
    . . . .
    (g)   If an appeal is filed under section 13-222-26,
    the certification process shall be stayed until the
    administrative appeal is resolved by the [BLNR] or
    chairperson [of the BLNR].
    6
    HAR § 13-222-26 provides, in relevant part:
    § 13-222-26   Appeal of shoreline certification.
    (a)   Upon timely application, the following persons
    or agencies may have standing to appeal:
    . . . .
    (4)   Other persons or agencies who can show a

    certification.
    B.
    2005 Shoreline Certification Application
    On June 27, 2005, Esaki Surveying and Mapping, Inc.
    filed an application for Shoreline Certification with the DLNR on
    behalf of Jeffrey Galloway (Galloway), the owner of the property.
    The purpose of the Shoreline Certification was to obtain a
    Building Permit.7     Galloway’s application was transmitted to
    State of Hawai#i Department of Accounting and General Services
    (DAGS) Surveyor Reid Siarot (Siarot).         See HAR § 13-222-10(a)

    (...continued)
    substantial interest in the matter; provided
    that the [BLNR] or chairperson [of the BLNR] may
    grant standing only if the person’s or agency’s
    participation will substantially assist the
    board or chairperson in its decision making.
    . . . .
    (c)   Any person or agency wishing to appeal shall
    file a notice of appeal in writing with the department
    no later than 20 calendar days from the date of the
    public notice of the proposed shoreline certification
    or rejection.
    (d)   The notice of appeal shall state the legal and
    factual basis for the appeal.
    (e)   Upon determination that a person or agency has
    standing to appeal, the chairperson [of the BLNR] by
    written order shall set forth the schedule for the
    briefs and requirements for the briefs.
    (f)   The sole issue on appeal shall be whether the
    proposed shoreline certification or rejection was
    proper.
    . . . .
    7
    The purpose of the shoreline certification process is “to
    standardize the application procedure for shoreline certifications for
    purposes of implementing the shoreline setback law and other related laws.”
    HAR § 13-222-1 (2003). HRS § 205A-43(a) (2001 Repl.) provides that
    “[s]etbacks along shorelines are established of not less than twenty feet and
    not more than forty feet inland from the shoreline.” The “shoreline setback
    lines,” along with the certified shoreline, dictate the location of the
    “shoreline area”, an area where there are limitations on the structures that
    may be built. See HRS § 205A-44 (2001 Repl.) (“[e]xcept as provided in this
    section, structures are prohibited in the shoreline area without a variance
    pursuant to this part.”).

    (2003) (“The state land surveyor shall review the . . .
    information provided by the applicant[.]”).
    Petitioners and Barbara Robeson sent a letter to Siarot
    requesting that a site visit be conducted during the winter
    months to determine the appropriate shoreline.            On April 12,
    2006, Siarot sent a letter to the DLNR stating that he had
    inspected the shoreline at the site, and that Dennis Esaki
    (Galloway’s surveyor), Petitioners, and others “participated in
    the site inspection.”       Siarot stated that, “[a]s a result of the
    inspection, the shoreline was determined to be at the debris line
    near the mauka[8] edge of the naupaka[9] hedge, further mauka
    than deliniated on the map.        Mr. Esaki was advised to revise his
    maps and photographs.”       (Emphasis added.)     Because Dennis Eskai
    had failed to return his calls or provide the requested
    information during a period of six months, Siarot recommended
    that, in accordance with HAR § 13-222-7(b)(15) and (I) (2003)10,

    “Mauka” means “inland”. See Mary Kawena Pukui & Sameul H. Elbert,

    HAR § 13-222-7 provides, in pertinent part:
    § 13-222-7   Application.
    (a) Application for shoreline certification shall be in
    writing, addressed and mailed to the [BLNR].
    (b) The application shall contain the following:

    Galloway’s application be rejected.         Galloway subsequently sold
    the property.
    2008 Shoreline Certification Application
    On January 11, 2008, Dobbin and Wagner filed a
    Shoreline Certification application with the DLNR for the same
    property.    The purpose of the certification was to obtain a
    building permit for Dobbin, the new owner of the property.               The
    DLNR accepted the application and transmitted it to Siarot.                 The
    application was also submitted for publication in the Office of
    Environmental Quality Control (OEQC) Environmental Notice, to
    allow for public comment.
    As with the 2005 shoreline certification, Petitioners
    sent a letter to Siarot requesting a site visit inspection and
    suggested that Siarot review his previous photographs and file
    for the property because of “[n]aupaka enroachment issues,

    reasonably necessary to evaluate the
    application.

    (I) If, upon review of an application, the [DLNR] or the
    state land surveyor finds: (1) noncompliance with any rule
    under this chapter, (2) irregularity in surveying methods
    utilized, or (3) the application or any information
    submitted by the applicant to be in error or a
    misrepresentation of the facts, then the application shall
    be denied and returned to the applicant, the 90-day time
    period shall cease, and the applicant shall be required to
    resubmit a new application.

    planted beach heliotropes[11], [and a] shoreline too seaward . .
    . .”        On April 18, 2008, a site visit was conducted.          A report of
    the site visit (report) indicates that the survey personnel were
    Siarot, Ian Hirokawa (Hirokawa), and Chris Conger, who were
    accompanied by Petitioners and Ron Wagner.              The report differed
    from the shoreline location recommended by Siarot in 2005, that
    “was considerably mauka” of the ocean:
    Shoreline: . . . . The profile started to mauka with a
    graded area in the lawn; then moved makai[ 12] to the
    berm of graded sand; then the orange construction
    fence; the start of the naupaka hedge and back of the
    dune, St. Augustine grass and Iron Wood debris on the
    west side; the dune crest and contact between old
    accumulated Iron Wood debris and fresh Iron Wood and
    other debris; the makai edge of the hedge ([n]aupaka,
    beach heliotrope, spider lily) and debris; beach face;
    recent debris line (cobble and gravel); the berm crest
    and berm face; makai edge of sand and start of beach
    rock; and most makai was the beach rock ridge and
    swash zone.
    . . . .
    Decision: Recommended the proposed shoreline for
    certification. A different location, considerably
    farther mauka on the back of the frontal dune, was
    identified as the shoreline location during an October
    19, 2005 site visit (KA-034-2A) by Dolan Eversole,
    Chris Conger, [] Siarot, and Morris Atta. There is no
    evidence that the wash of the waves has extended that
    far mauka in the past two winters, especially the most
    recent winter season.
    (Emphases added.)         Siarot sent a letter dated May 28, 2008 to the
    DLNR, Land Division Administrator, Morris M. Atta, recommending
    that “the State of Hawai#i should have no objections to adopting
    the dune crest as the shoreline as delineated on the map prepared
    by [Wagner].”

    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Notice of Appeal to the BLNR
    On June 8, the proposed shoreline certification for the
    property was published in the OEQC bulletin, and on June 27,
    2008, Petitioners filed a Shoreline Certification - Notice of
    Appeal, stating that “[t]he proposed shoreline certification does
    not properly or accurately locate the shoreline according to the
    upper reaches of the wash of the waves at high tide during the
    season of the year when the highest wash of the waves occurs.”
    On September 17, 2008, Hirokawa, a Project Development Specialist
    with the Land Division of DLNR, recommended to Laura Thielen, at
    that time the Chairperson of the BLNR (Chairperson Thielen), that
    the BLNR grant Petitioners standing to appeal the shoreline
    application13 and also grant Dobbin and Wagner standing to
    participate in the appeal.       Chairperson Thielen approved the
    recommendation on September 22, 2008, and issued an order
    notifying the parties of standing, the briefing schedule, limits
    on ex parte communications, and the potential for site
    inspections.
    In their brief to the BLNR, Petitioners cited to HRS §
    205A-1, which as stated, provides the statutory definition of
    “shoreline,” and argued that “[e]ach year, depending upon the
    size and direction of the swells, the winter waves repeatedly
    13
    The order attached to the recommendation stated that an
    organization called “North Shore Ohana” with an address that was “c/o Barbara
    Robeson” was deemed not to have standing in the matter due to its failure to
    present evidence or facts sufficient to establish a prima facie case to grant
    standing. Barbara Robeson was the other person, in addition to Petitioners,
    who had requested a site inspection for the property when Galloway’s
    application was under consideration.
    9
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    wash well into and beyond the currently proposed shoreline for
    [the property].”     With respect to their contention that
    Respondents Dobbin and Wagner’s proposed shoreline did not
    represent the shoreline in accordance with the definition at HRS
    § 205A-1, Petitioners argued several points.           First, they alleged
    that their evidence, in the form of photographs, was the “most
    credible” and that Siarot incorrectly located the shoreline
    “based solely in this case, upon ‘on the ground evidence,’ at the
    time of the April 18, 2008 site visit.”          (Emphases in original.)
    Second, Petitioners averred that “the State Surveyor ignore[d]
    his own recommendations of October 19, 2005, and further
    ignore[d] the importance of the historical evidence which
    confirms the Surveyor’s previous location of the shoreline . . .
    .”   (Emphases in original.)      They stated that, “[s]imply put, the
    DLNR’s current determination of the shoreline based upon a
    limited one year time frame, i.e. the particular year for which
    the certification is sought, is wrong as a matter of law.”
    In support of these first two arguments, Petitioners
    contended that the exhibits they provided,14 including
    photographic evidence, demonstrated the highest wash of the
    waves, and that the naupaka and heliotrope trees on the property
    14
    Petitioners provided, as exhibits to their brief to the BLNR, (1)
    Wagner’s proposed shoreline certification map for the property, (2) a December
    26, 2007 proposed shoreline certification map for the property, (3) a number
    of photographs, (4) Siarot’s letter dated April 12, 2006, (5) an email from
    DLNR employee Chris Conger dated May 30, 2008, and (6) testimony from Charles
    “Chipper” Wichman, Director of Limahuli Garden and Preserve, regarding naupaka
    plants (Wichman testimony). Petitioners also attached declarations from Beau
    Blair (Blair declaration), Caren Diamond (Diamond declaration), and Barbara
    Robeson (Robeson declaration).
    10
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    were acting as a “‘barrier’ which [was] prevent[ing] and[/]or
    hinder[ing] the observation of the true evidence of the debris
    line created by the upper wash of the winter waves.”             (Emphases
    in original.)    They alleged that the naupaka and other salt
    tolerant plants evidenced in the photographs were being used to
    create an artificial shoreline and resulted in a vegetation line
    that did not represent the “highest wash of the waves.”
    Finally, Petitioners contended that using the
    “artificial shoreline,” represented by the vegetation line on the
    property, as the certified shoreline was against public policy.
    They suggested that this court has held “that public policy
    ‘favors extending to public use and ownership as much of Hawaii’s
    shoreline as is reasonably possible[,]’” (quoting 
    Sotomura, 55 Haw. at 180
    , 517 P.2d at 61), and that their proposed shoreline,
    based on the 2005 State Surveyor recommendations, was in accord
    with this policy.
    Dobbin and Wagner Brief in Support of Their Proposed Shoreline
    On November 12, 2008, Dobbin and Wagner filed their
    answering brief with the BLNR.       First, they alleged that
    “[a]lthough the [DLNR] has historically been lenient in
    permitting lay witnesses to testify as to factual underpinnings,
    the ultimate determination of the upper reaches of the wash of
    the waves at high tide in the season of the year in which the
    highest wash of the waves occurs is one for experts and those
    qualified under the law.”      Thus, they related, the determination
    11
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    of the property shoreline as made by the licensed surveyor
    (Wagner), and as reviewed by Siarot and DNLR personnel, should be
    “afforded deference” as a matter of administrative law.
    Second, Dobbin and Wagner argued that Wagner’s
    determination of the shoreline, as affirmed by the State Surveyor
    and DLNR personnel was “supported by substantial evidence and
    complie[d] with all applicable statutory and regulatory
    requirements.”    Dobbin and Wagner contended that the proposed
    certified shoreline satisfied the two relevant indicators in the
    statutory definition of “shoreline” as set forth in HRS § 205A-1
    -- the vegetation line and the upper limit of debris.            They
    maintained that there were mature ironwoods and naupaka
    established makai of the dune crest and that the debris shown in
    Petitioners’ photos had originated from “falling branches and
    needles along the shoreline[,]” rather than from the wash of the
    waves.     According to Dobbin and Wagner, any debris that was from
    the waves had slid down the dune and thus was “back side debris”,
    rather than the “‘upper limit of debris left by the wash of the
    waves.’”     (Quoting HRS § 205A-1.) (Emphasis added.)
    In support of the shoreline proposed by Wagner, Dobbin
    and Wagner attached exhibits15 that included (1) an affidavit of
    15
    Respondents Dobbin and Wagner attached to their brief (1) the map
    of the proposed shoreline prepared by Wagner, (2) their original application
    to the BLNR for shoreline certification, (3) a copy of the notice of proposed
    shoreline certification in the OEQC Environmental Notice, (4) Petitioners’
    Notice of Appeal, (5) a declaration of Dobbin (Dobbin declaration), (6) a
    declaration of Galloway (Galloway declaration), (7) the Moody affidavit, (8)
    the Shook affidavit, (9) a copy of the DLNR’s “Report to the Twenty-Third
    Legislature Regular Session of 2006, Requesting a Review and Analysis of the

    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Steve Moody (Moody affidavit), the owner of the property before
    Galloway from 2000 to 2004, stating that there was no planting of
    vegetation along the shoreline front at any time; and (2) an
    affidavit of Danny Shook (Shook affidavit), who did landscaping
    work for Moody, stating that the irrigation and sprinklers in
    place “were not aimed towards nor intended to irrigate the
    naturally growing shoreline vegetation.”         Dobbin and Wagner
    alleged that Petitioners’ photographs indicated that “none of the
    sprinklers were aimed toward the shoreline vegetation.”            With
    respect to Petitioners’ proposed shoreline, Dobbin and Wagner
    contended that Petitioners’ shoreline was completely arbitrary,
    that “[t]here is no admissible proof to support their asserted
    line, nor anything to tie that line to the statutory criteria,”
    and that “the heavy natural growth of the naupaka fronting the
    shoreline renders it impossible to discern any line of debris at
    such a distance from the certified shoreline[.]”
    Third, Respondents Dobbin and Wagner alleged that all
    of Petitioners’ photographs “purporting to show a debris line
    from years past are irrelevant” because “[a]s a matter of law,
    wave events from past years do not and cannot establish the upper
    reach of the wash of the waves in the season of the year in which
    an applicant submits.”      (Citing In re Application of Sanborn, 57

    Issues Surrounding the Shoreline Certification Process for the Purpose of
    Establishing Shoreline Setbacks,” (DLNR Report to the Legislature) and (10) a
    “Problem Statement” by Chip Fletcher, Geologist at the University of Hawai#i,
    created as part of a 2005 Shoreline Working Group.
    13
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Haw. 585, 588, 
    562 P.2d 771
    , 773 (1977).)         Dobbin and Wagner
    contended that this interpretation of HRS § 205A-1 was
    appropriate because “[s]tatutes regulating, restraining or
    interfering with private property are subject to a strict
    construction” (citation omitted), and “where the terms of the
    statute are plain, unambiguous and explicit, as in this case, the
    appellate body is not at liberty to look beyond the statutory
    language for a different meaning[,]” (citations omitted).
    They also alleged that this “current year” requirement
    is recognized in the DLNR Report to the Legislature, in which it
    recommended that the term “‘annual’ means that the wave must have
    a statistical recurrence interval of at least once per year.”
    (internal quotation marks omitted.)        According to them, the
    requirement that an application for shoreline certification
    include maps “‘based on an actual field survey conducted within
    ninety (90) days prior to the filing . . . [,]’” (quoting HAR §
    13-222-9(c) (2003)), indicates that the map should be based on
    that year’s field survey alone.
    Fourth, they contended that even if other years could
    be considered by the BLNR, the evidence from preceding years of
    “gravity flow down the backside of the dune [on the property]
    [was] insufficient” to establish the “upper reaches of the wash
    of the waves[,]” because a gravity flow of debris down the dune
    does not mark the “upper reaches.”        According to Respondents
    Dobbin and Wagner, the statute uses the phrase “upper,” and that
    14
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    interpretation is consistent with the BLNR Report to the
    Legislature, which states that “‘run up’ means that the water
    position setting the shoreline must be derived exclusively by
    wave energy run-up, and not aided by gravity or funneling through
    narrow passages.”16     (Internal quotation marks omitted.)
    (Emphasis in original.)
    Fifth, they argued that the statutory definition of a
    shoreline recognizes the presence of vegetation as a possible
    shoreline indicia, and that the BLNR should not speculate on how
    far debris would travel absent intervening vegetation, because
    that would mean that it gave the debris line preference over the
    vegetation line, in contravention of Diamond v. State Board of
    Land & Natural Resources, 112 Hawai#i 161, 174, 
    145 P.3d 704
    , 717
    (2006) (Diamond I).      In other words, they maintained that if
    debris was stopped in its movement by the vegetation, the BLNR
    should allow the area where it stopped to represent the
    shoreline, rather than prioritizing a hypothetical debris line
    over an actual vegetation and debris line.
    The BLNR’s Denial of Petitioners’ Appeal
    On June 17, 2009, Hirokawa transmitted a memorandum to
    BLNR Chairperson Thielen, recommending that she deny Petitioners’
    appeal, “based upon [Petitioners’] failure to provide evidence to
    support the relocation of the shoreline at their proposed
    16
    Dobbin and Wagner did not explain how this proposed definition of
    “run up” from the BLNR Report to the Legislature should be read in conjunction
    with other regulations or with the statutory definition of “shoreline.”
    15
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    location.”     The memorandum stated that “[t]he evidence they
    provide is largely anecdotal, and the photographs provided, which
    are often undated, do show an increased growth in naupaka and
    various debris lines.       However, a closer examination of the
    photographic evidence provided fails to overcome their burden of
    proof to justify moving the shoreline to their proposed
    location.”     Attached to the memorandum were the Findings of Fact
    (findings), Conclusions of Law (conclusions), and Decision and
    Order.     Chairperson Thielen approved the memorandum on June 19,
    2009.17
    On June 19, 2009, Chairperson Thielen signed the
    memorandum and the “Findings of Fact, Conclusions of Law, and
    Decision and Order” (collectively, Decision).            She certified the
    shoreline in accordance with Wagner’s map and Hirokawa’s
    recommendation, on June 25, 2009.
    17
    The June 19, 2009 “Findings of Fact, Conclusions of Law, and
    Decision and Order” began with a preface that distinguished the certified
    shoreline from the “shoreline property boundaries” and the “private property
    line.“ The BLNR stated,
    Unlike shoreline property boundaries, certified shorelines
    are valid for a period of one year only (with an exception
    for shorelines along fixed manmade structures), and may in
    fact not coincide in the same location with shoreline
    property boundaries. Similarly, the private property line
    that delineates the public’s right of access along
    shorelines typically extends further mauka than both the
    certified shorelines and shoreline property boundaries
    because unlike the latter two, it is not limited by the
    exclusion of the effects of hurricanes and tsunamis on
    coastal areas.
    It appears that by using the phrase “private property line” the BLNR was
    referring to the boundary delininating a “beach transit corridor” pursuant to
    HRS § 115-5 (1993). A “beach transit corridor” designates an area where there
    is a public right of transit “along the shoreline below the private property
    lines[.]” 
    Id. It is
    unclear what statutory or regulatory definition the BLNR
    is referring to when it uses the general term “shoreline property boundaries.”
    16

    II.
    First Appeal - No. 30573
    Petitioners appealed the BLNR’s Decision to the court
    on July 20, 2009.    Petitioners challenged a number of the BLNR’s
    findings and conclusions, and argued that the Decision and Order
    was “arbitrary, capricious, or characterized by an abuse of
    discretion or clearly unwarranted exercise of discretion and
    wrong as a matter of law.”      (Quoting HRS § 91-14(g) (1993)18.)
    On March 2, 2010, the court heard oral arguments in the
    case, and on April 6, 2010, the court entered its “Findings of
    Fact, Conclusions of Law, Decision and Order.”          In its
    conclusions, the court held, inter alia, that:
    2.    HRS § 205A-1 defines “shoreline” as “the upper reaches
    of the wash of the waves, other than storm and seismic
    waves, at high tide during the season of the year in which
    the highest wash of the waves occurs, usually evidenced by
    the edge of vegetation growth, or the upper limit of debris
    left by the wash of the waves.”
    . . . .
    18
    HRS § 91-14(g) provides:
    (g) Upon review of the record the court may
    affirm the decision of the agency or remand the case
    with instructions for further proceedings; or it may
    reverse or modify the decision and order if the
    substantial rights of the petitioners may have been
    prejudiced because the administrative findings,
    conclusions, decisions, or orders are:
    (1) In violation of constitutional or statutory
    provisions; or
    (2) In excess of the statutory authority or
    jurisdiction of the agency; or
    (3)Made upon unlawful procedure; or
    (4) Affected by other error of law; or
    (5) Clearly erroneous in view of the reliable,
    probative, and substantial evidence on the whole
    record; or
    (6) Arbitrary, or capricious, or characterized
    by abuse of discretion or clearly unwarranted
    exercise of discretion.
    17
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    8.    The BLNR’s characterization as either ‘anecdotal
    evidence and/or unreliable evidence’ with respect to both
    the detailed Declarations of [Petitioners and Robeson], and
    the photographs they submitted in support of their appeal is
    arbitrary, capricious and/or characterized by an abuse of
    discretion or clearly unwarranted exercise of discretion,
    not in accordance with HAR § 13-222-10.
    9.    The map of the certified shoreline published on June
    8, 2008 and signed by the Chairperson on June 25, 2009 based
    upon the “conditions existing on December 4, 2007" does not
    correctly reflect the “upper reaches of the wash of the
    waves at high tide during the season of the year in which
    the highest wash of the waves occurs”, as provided in HRS §
    205A-1.
    . . . .
    12.   The current certified shoreline appears to incorrectly
    allow for the manipulation of the shoreline based upon
    artificially induced and enhanced vegetation, not in
    accordance with HRS § 205A-1.
    13.   The BLNR’s interpretation of HRS § 205A-1, et. seq.
    that only the ”current” year’s evidence of the upper reaches
    of the wash of the waves should be considered in determining
    the shoreline is arbitrary, capricious and/or characterized
    by an abuse of discretion or clearly unwarranted exercise of
    discretion in applying HRS § 205A-1, et. seq., as it
    conflicts with and/or contradicts the purpose and intent of
    HRS § 205A-1, et. seq.
    . . . .
    17.   The BLNR’s interpretation of HRS § 205A-1 to limit its
    analysis of the upper reaches of the wash of the waves for
    only the “current” season is contrary to the intent of the
    statute and public policy to preserve as much shore as
    reasonably possible for public use.
    (Emphases added.)     In its Decision and Order, the court vacated
    the BLNR’s initial Decision and remanded to the BLNR with
    “specific instructions to appropriately consider and give due
    weight to [Petitioners’] proposed evidence and to correctly apply
    the applicable statutes, case law and administrative rules . . .
    .”   On May 19, 2010, the court entered its judgment in the case.
    Soon thereafter, on June 17, 2010 Dobbin and Wagner
    appealed from the court’s final judgment to the ICA (first
    18
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    appeal), and the BLNR filed a cross-appeal on June 21, 2012.
    III.
    The BLNR’s Amended Decision
    In the meantime, on May 21, 2010 in conjunction with
    the court’s remand, the BLNR filed its Amended Decision.            In
    addition to revising, to some extent, the findings in its first
    decision, the BLNR added additional findings and conclusions.
    Among the changes was the addition of a section in the findings
    titled “Prior Application for Shoreline Certification,” which
    discussed the DLNR’s actions with respect to the 2005 Galloway
    application.   The new findings also included, inter alia, the
    following statements:
    27.   The DLNR and State Surveyor also incorporate in their
    shoreline determination, any pertinent information about the
    shoreline that is presented by the owner of the subject
    property and any other member of the public that has
    personal knowledge and familiarity with the shoreline
    conditions of the subject property during high surf
    conditions in the season of high surf.
    . . . .
    37.   During the site visit the State Surveyor and
    DLNR staff noted that a different location, on the
    back of the frontal dune, was identified during a
    previous site visit on October 19, 2005; which was
    considerably further mauka than the proposed shoreline
    location in the Dobbin application.
    38.   The State Surveyor and DLNR staff also noted
    that there was no evidence that the wash of the waves
    had extended that far mauka in the past two winters,
    especially not during the immediately preceding winter
    season.
    RECOMMENDATION OF THE STATE SURVEYOR
    39.   On May 28, 2008, in a letter to the [DLNR], the
    State Surveyor stated that the State of Hawai#i had no
    objections to adopting the dune crest as the shoreline
    location, as delineated on the map prepared by []
    Wagner.
    40.   This recommendation was based, at least in part,
    on the Galloway application, the Dobbin application,
    and the site inspection conducted on April 18, 2008.
    19
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    41.   At the time of the recommendation, the State
    Surveyor was aware that two years prior the
    recommended location of the shoreline for the []
    [p]roperty was further mauka than the current
    location.
    (Emphases added.)
    The Amended Decision included a separate section of
    findings setting forth in more detail the evidence presented by
    Petitioners, and the BLNR’s evaluation of that evidence.            For
    example, the findings stated, inter alia, with respect to the
    Blair Declaration, that:
    46.   [Petitioner] Blair’s testimony did not refer to
    specific observations she made of the shoreline,
    either as to the location of the highest wash of the
    waves or any dates when these high tides occurred.
    47.   [Petitioner] Blair also testified regarding
    photographs which were attached to [Petitioners’]
    Opening Brief at 9-12.
    48.   The photographs contained in Exhibits G through
    N of [Petitioners’] Opening Brief are date stamped,
    either on the photos or in the captions, with dates
    falling between 2004 and 2008.
    49.   [Petitioner] Blair testified that the photos
    show “the upper reaches of the wash of the waves
    during the season of the year in which the highest
    wash of the waves occurs on the Dobbin property.” []
    50.   The photos enumerated in [Petitioner] Blair’s
    testimony do not all contain depictions of waves.
    51.   It is not possible to ascertain from [Petitioner]
    Blair’s testimony what was the object of specific
    photographs or what they were purported to portray.
    52.   [Petitioner] Blair’s testimony did not contain any
    information as to the dates when specific photographs were
    taken or who took the photographs.
    . . . .
    56.   [Petitioner] Blair’s and [Petitioner] Diamond’s
    testimony do not clearly identify what each photograph is
    purporting to depict.
    (Emphases added.)    Similarly, the Amended Decision set forth the
    20
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    evidence provided by Respondents Dobbin and Wagner in a section
    titled, “Evidence Presented by Appellees Dobbin[][,]” although
    this section did not discuss the DLNR’s evaluation of that
    evidence.    The new and revised findings on Dobbin and Wagner’s
    evidence included, inter alia,
    69.   [Respondents] Dobbin and Wagner’s Opening Brief
    refuted the assertions that the vegetation growing along the
    shoreline was planted and “induced” with the aid of
    irrigation. []
    70.   [Respondents] Dobbin and Wagner, as part of their
    Answering Brief, presented an affidavit and a couple of
    declarations from people who had owned the [] [p]roperty
    during the period from 2000 to present. []
    71.   The current and prior owners all denied ever planting
    anything along the makai side of the [] [p]roperty. []
    72.   [Moody], the owner of the [] [p]roperty from 2000 to
    2004, admitted to having an irrigation system [on] the
    property, but he testified that the system was located
    several feet away from the edge of the naupaka growing along
    the shoreline and that all of the sprinkler heads were aimed
    so the spray would be parallel to or away from the
    shoreline. []
    73.   [Respondent] Dobbin also submitted testimony from
    [Shook], the contractor for [Moody], who testified that when
    he was hired in late 2003 there [were] already naupaka and
    ironwood trees, with possibly beach heliotropes and wedelia,
    growing closest to the shoreline. []
    . . . .
    75.   [Shook] also testified that an irrigation system was
    installed on the [] [p]roperty for the purpose of irrigating
    the lawn and that the sprinkler heads were aimed so that the
    spray pattern would be in a mauka direction or parallel to
    the shoreline in a deliberate attempt to avoid the
    irrigation of the naupaka and other vegetation growing along
    the shoreline. []
    (Emphases added.)
    The BLNR’s conclusions stated, inter alia,
    5.    HRS § 205A-1 and HAR § 13-222-2 defines the shoreline
    as:
    [T]he upper wash of the waves, other than storm and
    seismic waves, at high tide during the season of the
    year in which the highest wash of the waves occurs,
    21
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    usually evidenced by the edge of vegetation growth, or
    the upper limit of debris left by the wash of the
    waves.[ 19]
    . . . .
    7.    Shoreline certifications are expressly limited to a
    twelve month validity period, except in the circumstance
    where there is a legal artificial structure. HRS § 205A-
    42(a) and HAR § 13-222-11.[ 20]
    9.    The multi-variable approach used by the DLNR and State
    Surveyor is the most reasonable and appropriate method for
    determining the location of the shoreline for shoreline
    certification purposes pursuant to HRS § 205A-1 and HAR §
    13-222-2.
    . . . .
    11.   [Petitioners] failed to establish by a preponderance
    of the evidence that the proposed certified shoreline was
    not proper.
    (Emphasis added.)
    IV.
    Appeal from the BLNR’s Amended Decision - CAAP-11-000345
    On May 25, 2010, Petitioners filed a Notice of Appeal
    to the circuit court,21 appealing the BLNR’s Amended Decision
    (second appeal).       On August 3, 2010, the circuit court granted
    Petitioners’ July 1, 2010 Motion to Reassign Case, and reassigned
    the case to the court that heard the first appeal.
    A.
    Petitioners filed their opening brief on September 30,
    19
    As will be discussed infra, this definition, apparently quoted, is
    not actually what is provided by HRS § 205A-1 and HAR § 13-222-2. Those
    provisions differ from the BLNR’s recitation, in that they state that
    “‘shoreline’ means the upper reaches of the washes of the waves,” rather than
    the BLNR’s quote which states that it is “the upper wash of the waves.” See
    HRS § 205A-1 and HAR § 13-222-2.
    20
    It is noted that there was no COL No. 8 in the BLNR’s Amended
    Decision.   The COLs went directly from No. 7 to No. 9.
    21
    “Circuit court” refers to the Circuit Court of the Fifth Circuit
    presided over by the Honorable Randal G.B. Valenciano.
    22
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    2010, alleging that the Amended Decision “clearly is not
    consistent with the [c]ourt’s April 6, 2010 Decision and Order,
    and constitutes an unwarranted abuse of the Chairperson’s
    discretion in recertifying the shoreline in the same place as
    previously vacated by [the] [c]ourt.”         (Emphases in original.)
    Petitioners reiterated their arguments from their previous
    appeal, contending that the new findings in the Amended Decision
    relating to the characterization of Petitioners’ evidence were
    clearly erroneous and an abuse of discretion, and concluding that
    the recertification of the shoreline to the same location as
    previously vacated by the court was arbitrary, capricious or
    characterized by an abuse of discretion.
    Dobbin and Wagner filed their answering brief on
    November 9, 2010, averring that the BLNR adhered to the court’s
    directions in its April 6, 2010 Decision and Order, gave due
    weight to the evidence of Petitioners, and correctly applied the
    applicable law in confirming Dobbin and Wagner’s proposed
    shoreline.    The BLNR’s answering brief was also filed on November
    9, 2010, alleging that its determination of the shoreline
    location was entitled to deference, and that its interpretation
    HRS § 205A-42 as the location of the high tide during the season
    of the current year in which the highest wash of the waves occurs
    was not arbitrary and capricious.22        Petitioners filed a reply
    22
    Despite arguing in favor of a “current year” interpretation of HRS
    § 205A-42, the BLNR had indicated that it took Petitioners’ historical
    evidence, which included the past years’ wash of the waves, into account in
    (continued...)
    23
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    brief on November 24, 2010, concluding, inter alia, that “[t]he
    BLNR’s decision that [Petitioners] have not provided evidence to
    meet its burden of proof as to the location of the shoreline is
    in and of itself incredible.”         (Emphasis in original.)
    B.
    The court heard oral arguments in the second appeal on
    January 5, 2011.       Each of the parties was asked to submit
    proposed findings of fact, conclusions of law and a proposed
    order.     On February 16, 2011, the court entered its Findings of
    Fact (findings), Conclusions of Law (conclusions), Decision and
    Order (collectively, Second Decision) in this second appeal.                The
    court’s findings included, inter alia,
    33.   The vegetation planted on Lot 12 during
    December, 2003, and January and February, 2004 has
    been artificially induced by human intervention and
    does not represent evidence of the shoreline.
    . . . .
    40.   The evidence submitted by [Petitioners], including the
    photographs, clearly shows that the “upper reaches of the
    waves, other than storm and seismic waves, at high tide
    during the season of the year in which the highest wash of
    the waves occurs” reaches further mauka onto [the property]
    than the BLNR’s “current” location of the shoreline at the
    “dune crest.”
    (Emphases added.)       The court included the following conclusions,
    8.    The BLNR’s characterization as unreliable the
    evidence with respect to both [Petitioners’
    declarations], and the photographs submitted in
    support of the appeal is arbitrary, capricious, and
    constitutes an abuse of discretion or unwarranted
    exercise of discretion.
    . . . .
    22
    (...continued)
    making its determination.   The BLNR argued that less weight should be given to
    historical evidence.
    24
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    10.   The vegetation planted on lot 12 in 2003 and
    2004 was planted seaward of the shoreline as located
    by [] Siarot, State Surveyor at the October 19, 2005
    site visit to the subject property. This artificially
    induced and enhanced vegetation is incorrectly being
    used to currently locate the shoreline and/or hinder
    the true evidence of the location of the shoreline in
    accordance with HRS § 205A-1.
    . . . .
    12.   The May 21, 2010 recertified shoreline
    incorrectly allows for the manipulation of the
    shoreline based on artificially induced and enhanced
    vegetation.
    . . . .
    23.   The BLNR’s interpretation of HRS § 205A-1 and
    HRS § 205A-42 which is based upon the limited duration
    of a shoreline certification in conjunction with the
    definition of shoreline, and which requires that the
    BLNR’s certified shoreline determination reflect the
    “current” location of the shoreline is arbitrary,
    capricious and constitutes an abuse of discretion or
    unwarranted exercise of discretion.
    (Emphases added.)    Finally, it set forth its Decision and Order,
    as provided below.
    1.    The BLNR’s [Amended Decision] is hereby reversed
    and vacated.
    2.    The certified shoreline as delineated on the
    shoreline survey map for the subject property that was
    published for final certification in the OEQC Bulletin
    on June 8, 2008 and reapproved and reaffirmed by the
    BLNR’s Chairperson, [] Thielen on May 21, 2010 is
    hereby reversed and vacated.
    3.    The shoreline for [the property] should be
    located approximately 20 feet mauka of the shoreline
    as shown on the shoreline certification map published
    for final certification on June 8, 2008 and resigned
    by the Chairperson on May 21, 2010.
    4.    Any further certified shoreline proceedings
    before the BLNR for [the property] shall be consistent
    with this [c]ourt’s Findings of Fact; Conclusions of
    Law; Decision and Order.
    (Emphases added.)    The court entered its judgment on March 31,
    2011.
    25
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    In the second appeal, Dobbin and Wagner and the BLNR
    appealed the judgment to the ICA, challenging the court’s order
    vacating the BLNR’s Amended Decision and locating the shoreline
    “approximately 20 feet mauka.”

    The ICA issued an order on August 25, 2011 granting
    Petitioners’ motion to consolidate the first and second appeals,
    No. 30573 and CAAP XX-XXXXXXX, and ordering the parties to file
    briefs for CAAP-11-0000345.         On August 31, 2012, the ICA issued
    its Memorandum Opinion in the consolidated cases on August 31,
    2012.    Diamond v. Dobbin, Nos. 30573 & CAAP-11-0000345, 
    2012 WL 3792024
    , at *1 (App. Aug. 31, 2012) (mem.).            It observed that on a
    secondary appeal from an administrative agency decision,
    the appellate court will utilize identical standards applied
    by the circuit court. Questions of fact are reviewed under
    the “clearly erroneous” standard. In contrast, an agency’s
    legal conclusions are freely reviewable. An agency’s
    interpretation of its rules receives deference unless it is
    plainly erroneous or inconsistent with the underlying
    legislative purpose.
    
    Id. (quoting Hawai#i
    Teamsters & Allied Workers, Local 996 v.
    Dep’t of Labor & Indus. Relations, 110 Hawai#i 259, 265, 
    132 P.3d 368
    , 374 (2006)).       First, the ICA concluded that the court had
    “engaged in unwarranted fact[-]finding and weighing of the
    evidence.”      
    Id. It held
    that, contrary to the court’s conclusion
    8, set 
    forth supra
    , the BLNR did not “disregard” the evidence
    26
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    submitted by Petitioners.23      
    Id. Rather, the
    BLNR found the
    findings of the DLNR and the State Surveyor that were based on
    the 2008 site visit, to be persuasive.          
    Id. The ICA
    indicated
    that the BLNR had acknowledged in its Amended Decision that the
    DLNR and State Surveyor had identified a shoreline further mauka
    in response to the Galloway application, and that the BLNR had
    addressed this by noting that there was no evidence that the
    waves had extended to the October 19, 2005 shoreline in the
    previous two winters.      
    Id. According to
    the ICA, the “BLNR was
    presented with adequate evidence supporting its ultimate
    shoreline determination, and as such, its findings were not
    clearly erroneous.”      
    Id. “Therefore,” the
    ICA held, “the []
    court erred in failing to give proper deference to [the] BLNR’s
    findings of facts in certifying the shoreline boundary.”             
    Id. Second, the
    ICA concluded that the court improperly
    characterized the BLNR’s findings as only taking into
    consideration evidence from the current year’s upper reaches of
    the wave.    
    Id. at *5.
       In accordance with the BLNR’s Amended
    Decision, the ICA reasoned that the BLNR “did not restrict its

    Respectfully, the ICA opinion is not entirely clear as to which of
    the appeals it is addressing with respect to the court’s “unwarranted fact
    finding,” although it initially states that “we do not address the issues
    raised in [No.] 30573.” 
    2012 WL 3792024
    , at *3. First, it states that the
    court engaged in unwarranted fact finding in its second appeal, and cites to
    findings 28 through 40 in that Decision and Order. 
    Id. Then, the
    ICA states
    that “[b]ased on the evidence submitted by [Petitioners] the [] court
    concluded that . . . [,]” and quotes two conclusions from the court’s April 6,
    2010 Decision and Order in the first appeal. 
    Id. at *4.
    Later in the
    opinion, the ICA identifies findings 27 through 38 and conclusions 8 and 9
    from the first appeal, stating that the court erred in making those
    determinations, and then quotes language that is found in the BLNR’s
    conclusions in both the first and second appeal. 
    Id. at *4-5.

    analysis of the upper reaches of the waves to the current year,
    but rather, ‘took into evaluation all relevant factors present on
    the [p]roperty.’”     
    Id. (brackets omitted).
          Thus, it held that
    the BLNR’s analysis, taking into account all relevant factors,
    was not contrary to the definition of “shoreline boundary” in HRS
    § 205A-1, because both the debris line and vegetation line are
    “used as evidence to determine the shoreline, depending on the
    location and stability of each line.”

    112

    ).
    VI.
    On December 3, 2012, Petitioners filed their
    Application to this court.       They ask whether the ICA gravely
    erred (1) “in its [f]ailure to [c]onsider and [a]pply [this
    court’s d]ecision in Paul’s Elec[tric] Serv[ice] Inc. v. Befitel,
    104 Hawai#i 412, 
    91 P.3d 494
    (2004)[,] . . . with respect to the
    ‘deference,’ if any, the [] [c]ourt should have afforded the
    [BLNR] in the [] [c]ourt’s review of the BLNR’s . . . location of
    the ‘shoreline’ pursuant to HRS [§] 205A-1, et. seq.”; (2) “in
    its [i]nterpretation and [a]pplication of . . . [Diamond I], with
    respect to the . . . determination of the shoreline . . . .”; and
    (3) “in [c]oncluding that the [] [c]ourt’s 2010 Judgment in Civil
    No. 09-1-0197 [No. 30573] was [r]endered [m]oot when the BLNR
    filed its Amended Decision [] on May 21, 2010.”24
    24
    On December 18, 2012, the BLNR filed a Response Brief (Response),
    arguing that the ICA properly determined that the court should not have made
    its own determinations by weighing the evidence on appeal, and that regardless

    VII.
    Preliminarily, the mootness issue must be addressed,
    inasmuch as it affects the relevancy of the proceedings below to
    the instant appeal.      “The mootness doctrine is said to encompass
    the circumstances that destroy the justiciability of a suit
    previously suitable for determination.”          Wong v. Bd. of Regents,
    Univ. of Haw., 
    62 Haw. 391
    , 394, 
    616 P.2d 201
    , 203 (1980).
    Hence, “[a] case is moot if the reviewing court can no longer
    grant effective relief.”       Kaho#ohanohano v. State, 114 Hawai#i
    302, 332, 
    162 P.3d 696
    , 726 (2007) (brackets in original)
    (citations omitted).      However, this court has also “recognized an
    exception to the mootness doctrine in cases involving questions
    that affect the public interest and are ‘capable of repetition
    yet evading review.’”      Diamond I, 112 Hawai#i at 
    170, 145 P.3d at 713
    (quoting Okada Trucking Co., Ltd. v. Bd. of Water Supply, 99
    Hawai#i 191, 196, 
    53 P.3d 799
    , 804 (2002) (citations omitted)).
    Petitioners allege in their Questions Presented and in
    footnote 3 of their Application, that the court’s May 19, 2010
    Judgment entered on the first appeal, No. 30573, is not moot.
    (Citing Diamond I, 112 Hawai#i at 
    171-72, 145 P.3d at 714-15
    .)
    Diamond I addressed a similar factual situation to the one
    presented here, involving shoreline certifications.            As stated,
    24
    (...continued)
    of Petitioners’ citation to Paul’s Electric, the BLNR should be afforded
    deference in its decision based on a multi-variable approach. The Response
    also alleged that the ICA properly determined that the BLNR’s Amended Decision
    rendered the first appeal moot.
    29
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    under the relevant statutory scheme, a particular shoreline
    certification is only valid for one year.         See HRS § 205A-42
    (“[N]o determination of a shoreline shall be valid for a period
    longer twelve months.”)     In Diamond I, this court considered
    whether it could hear an appeal from a decision of the BLNR
    related to shoreline certification, despite the fact that the
    shoreline certification at issue had expired.          112 Hawai#i at
    
    172, 145 P.3d at 715
    .
    We determined the case was not moot because the
    shoreline certification satisfied the elements of the public
    interest exception to the mootness doctrine, specifically, it was
    “a matter of vast public importance” and was “‘capable of
    repetition yet evading review.’”         
    Id. (citing Okada
    Trucking Co.
    v. Bd. of Water Supply, 99 Hawai#i 191, 196-97, 
    53 P.3d 799
    , 804-
    05 (2002)).    Given that any shoreline certification would only be
    valid for one year, and that “the appeals process generally takes
    more than one year,” Diamond I recognized that appellate review
    would be frustrated if it determined that the appeal was moot.
    Therefore, Diamond I applied the exception to the mootness
    doctrine.
    This case is unlike Diamond I with respect to the
    mootness issue.    None of the parties appear to dispute the issue
    of whether this court may hear the appeal from the BLNR’s
    ultimate shoreline determination.        Instead, the issue is simply
    whether this court still must consider the court’s decision on
    30
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    appeal from the BLNR’s first shoreline determination, No. 30573.
    Here, the BLNR’s May 21, 2010 Amended Decision replaced
    the BLNR’s original June 19, 2009 Decision.           The issuance of the
    Amended Decision effectively “destroyed justiciability” of the
    prior appeal from the court’s judgment on the BLNR’s June 19,
    2009 Decision, inasmuch as the Amended Decision became the
    ultimate agency decision in effect regarding the shoreline
    certification on the property.        Thus, any appeal from the
    original administrative agency Decision in No. 30573 was mooted
    because the BLNR’s June 19, 2009 Decision is no longer effective.
    Instead, we will review the appeal from the May 21, 2010 Amended
    Decision of the BLNR.25
    VIII.
    Petitioners argue that the ICA failed to consider
    Paul’s Electric when discussing what deference the court should
    have given to the BLNR.       Respectfully, the ICA did err in setting
    forth part of its standard of review.         In articulating that
    standard, the ICA stated that “an appellate court’s review of an
    agency decision is ‘qualified by the principle that the agency’s
    decision carries a presumption of validity and appellant has the
    heavy burden of making a convincing showing that the decision is
    25
    However, we observe that the BLNR’s June 19, 2009 Decision will be
    relevant to the extent necessary to determine the validity of the BLNR’s
    Amended Decision, including whether the BLNR complied with the court’s order
    on remand. See discussion infra.

    invalid because it is unjust and unreasonable in its
    consequences.’”       Dobbin, 
    2012 WL 3792024
    , at *3 (emphases added)
    (quoting Paul v. Dep’t of Transp., 115 Hawai#i 416, 426, 
    168 P.3d 546
    , 555 (2007)).
    Paul’s Electric, however, clarified several aspects of
    the standard for appellate review of administrative agency
    actions, including the “presumption of validity”, “heavy burden”,
    and “unjust and unreasonable” language set out by the ICA in its
    memorandum opinion.        See 104 Hawai#i at 
    417-20, 91 P.3d at 499
    -
    502.    This court held in Paul’s Electric, first, that although
    “this court has frequently used the ‘unjust and unreasonable’
    language as a proxy for the abuse of discretion standard . . .
    [,] the ‘unjust and unreasonable’ language has particular
    applicability only in the context of decisions of the Public
    Utilities Commission . . . .”          104 Hawai#i at 
    419, 91 P.3d at 501
    (emphasis added).       See also Nakamura v. State, 98 Hawai#i 263,
    274-75, 
    47 P.3d 730
    , 741-43 (2002) (Acoba, J., concurring and
    dissenting) (observing that the history of the “unjust and
    unreasonable” language demonstrates its inapplicability to cases
    not involving the Public Utilities Commission. (citing In re
    Application of Kauai Elec. Div. of Citizens Utilities Co., 
    60 Haw. 166
    , 179, 
    590 P.2d 524
    , 535 (1978))).            Since this case does
    not involve the Public Utilities Commission, the “unjust and
    unreasonable” language is not applicable here.             Second, Paul’s
    Electric held, with respect to the phrase, “the agency’s decision
    32
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    carries a presumption of validity and appellant has the heavy
    burden of making a convincing showing[,]” that “[a]gency
    determinations, even if made within the agency’s sphere of
    expertise, are not presumptively valid[.]”         
    Id. (emphases added);
    see also Nakamura, 98 Hawai#i at 
    273, 47 P.3d at 740
    (Acoba, J.,
    concurring dissenting) (“Presuming the validity of the [agency’s]
    decision as to credibility and weight, or because of its
    ‘expertise,’ undermines the clearly erroneous rule imposed by
    [HRS § 91-14(g)(5)].”).     Thus, the language regarding the
    presumptive validity of an agency determination is not applicable
    in the instant case either.      Therefore, in light of this court’s
    holding in Paul’s Electric, the ICA and Respondents erred when
    they articulated that standard of review.
    Notwithstanding that error, the ICA correctly
    articulated the “clearly erroneous” standard with respect to the
    court’s findings, see Hawaii Teamsters, 110 Hawai#i at 
    265, 132 P.3d at 374
    , and de novo review with respect to the court’s
    conclusions of law, id.; see also Lanai Co. v. Land Use Comm’n,
    105 Hawai#i 296, 307, 
    97 P.3d 372
    , 383 (2004) (“The courts may
    freely review an agency’s conclusions of law.”) (brackets,
    internal quotation marks, and citation omitted).           Accordingly, we
    will review the court’s findings of fact under the “clearly
    erroneous” standard and its conclusions of law under the de novo
    standard, without any particularized presumption of validity or
    need to consider whether the agency’s decision was “unjust and
    33
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    unreasonable.”     See Paul’s Electric, 104 Hawai#i at 
    418-20, 91 P.3d at 499-502
    .
    IX.
    Petitioners’ first question presented also appears to
    challenge the ICA’s conclusion that “[t]he [] court erred in
    substituting its judgment for [the] BLNR.”          Dobbin, 
    2012 WL 3792024
    , at *5 (emphasis added).          It is well-established that
    when a circuit court reviews an agency determination under HRS §
    91-14, that court acts as an appellate court.           Pursuant to HRS §
    91-14(f), a review of an agency decision “shall be conducted by
    the appropriate court . . . and shall be confined to the record.”
    Under HRS § 91-14(g), findings of fact are reviewable as to
    whether an agency’s decision is clearly erroneous in view of
    reliable, probative, and substantial evidence on the whole
    record.   Morimoto v. Bd. of Land & Natural Res., 107 Hawai#i 296,
    302, 
    113 P.3d 172
    , 178 (2005).
    Respectfully, the court went beyond determining whether
    particular conflicting findings were clearly erroneous, and
    instead made its own factual findings on appeal from the BLNR’s
    Amended Decision.26     The court did not err in stating its
    26
    In its Opening Brief to the ICA, the BLNR argues that the court
    erred in considering the evidence attached by Petitioners to their brief to
    the court on appeal. The BLNR states that, “[a]lthough the declarations
    appear to be the same declarations that were submitted in [Petitioners’]
    briefs before the [BLNR], no statement to that effect was contained in any of
    the [Petitioners’] briefs submitted to the [] court.” The appendix material
    provided by the Petitioners was identical to that in the record on appeal,
    however, and thus, although the court failed to cite to the record and instead
    cited to the appendices to the briefs, any error on the part of the court was
    harmless.
    34
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    conclusions, however, as those adhered to the standards for
    appellate review as set forth above.         For example, unlike the
    court’s findings, which are designated in its decision as
    “Findings of Fact,”27 the court’s conclusions state that
    particular findings from the BLNR’s Amended Decision were
    “clearly erroneous.”      However, as discussed infra, the court was
    correct in holding that certain findings in the BLNR’s Amended
    27
    The court articulated these factual determinations in the
    following findings in its February 16, 2011 decision on the second appeal:
    32.   Subsequent to the planting of the naupaka
    and beach heliotrope trees, [Petitioners] also
    observed and photographed irrigation lines on Lot 12,
    which were used to water the newly planted vegetation.
    []
    33.   The vegetation planted on Lot 12 during
    December, 2003, and January and February, 2004 has
    been artificially induced by human intervention and
    does not represent evidence of the shoreline.
    . . . .
    36.   The beach fronting [the property] is
    currently covered with salt tolerant naupaka and beach
    heliotrope trees planted by the prior owner to create
    an artificial shoreline.
    39.   The naupaka and beach heliotropes planted
    on [the property] act as a barrier that prevents
    and/or hinders the observation of the true debris line
    that evidences the “upper reaches of the wash of the
    waves at high tide during the season of the year in
    which the highest wash of the waves occurs.”
    40.   The evidence submitted by the
    [Petitioners], including the photographs, clearly
    shows that the “upper reaches of the wash of the
    waves, other than storm and seismic waves, at high
    tide during the season of the year in which the
    highest wash of the waves occurs” reaches further
    mauka onto [the property] than the BLNR’s “current”
    location of the shoreline at the “dune crest.”
    (Emphases added.)
    35
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Decision were clearly erroneous.28
    X.
    To reiterate, HRS § 205A-42(a) states that:
    The [BLNR] shall adopt rules pursuant to chapter 91
    prescribing procedures for determining a shoreline and
    appeals of shoreline determinations that are consistent with
    subsection (b); provided that no determination of a
    shoreline shall be valid for a period longer than twelve
    months, except when the shoreline is fixed by artificial
    structures that have been approved by appropriate government
    agencies and for which engineering drawings exist to locate
    the interface between the shoreline and the structure.
    (Emphasis added.)     The rules adopted by the BLNR are also subject
    to the definition of “shoreline” in HRS § 205A-1.            The
    regulations promulgated by the BLNR as to shoreline
    certifications can be found at HAR chapter 13, subchapter 222.
    In deference to the statutory definition, HRS § 13-222-2 defines
    “shoreline” the same as HRS § 205A-1 does.          A “‘[s]horeline
    certification’” is defined as “a signed statement by the
    chairperson of the [BLNR] that the shoreline is as located and
    shown on the map as of a certain date.”          HRS § 13-222-2.
    While HRS § 205A-42 limits the validity of a shoreline
    certification to one year, a particular certification may have
    consequences lasting beyond one year, because the purpose of a
    shoreline determination is “to standardize the application
    28
    In the court’s conclusion 1, it indicated that the BLNR’s findings
    27, 34, 35, 36, 38, 40, 41, 46, 48, 50, 51, 52, 53, 56, 58, 59, 60, 66, 68,
    69, 70, 72, and 73 in the BLNR’s Amended Decision were “clearly erroneous in
    view of the reliable, probative and substantial evidence on the whole record.
    The court also stated, at conclusion 2, that the BLNR’s conclusions 4, 9, 10,
    and 11 were “in violation of HRS § 205A-1, in excess of the BLNR’s statutory
    authority or jurisdiction, affected by other errors of law, and clearly
    erroneous in view of the reliable, probative and substantial evidence on the
    whole record.” Some, but not all, of the findings that the court indicated
    were clearly erroneous are addressed infra.
    36
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    procedure for shoreline certifications for purposes of
    implementing the shoreline setback law and other related laws.”
    HAR § 13-222-1 (emphasis added).         As related, “shoreline setback
    lines” are established running parallel to the “shoreline[,]” as
    certified by the BLNR.     See HRS § 205A-43(a) (1993) (“Setbacks
    along shorelines are established of not less than twenty feet and
    not more than forty feet inland from the shoreline.”).            The
    “shoreline setback lines”, in turn, dictate where certain
    structures can be built in relation to the seashore.            See HRS §
    205A-44 (stating that “[e]xcept as provided in this section,
    structures are prohibited in the shoreline area without a
    variance pursuant to this part.”).        Thus, if the shoreline
    setback line is dependent upon the shoreline certification, then
    structures may or may not be built in a particular area depending
    on where that certification is located.         Such structures would
    presumably be in existence for more than one year.           Hence, the
    shoreline determination can be a significant designation,
    resulting in ramifications for more than just one year.
    Moreover, the location of a “shoreline” can be relevant
    to the well-established public right of access to Hawai#i’s
    shorelines.   See HRS § 115-4 (1993) (providing for the right of
    transit along the shorelines).       HRS § 115-5(a) (1993) states that
    “[t]he right of transit shall exist seaward of the shoreline and
    this area shall be defined as a beach transit corridor.            For
    purposes of this section, ‘shoreline’ shall have the same meaning
    as in section 205A-1.” (emphasis added).         The right of the public
    37
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    to access a beach transit corridor is not at issue in this case.
    However, inasmuch as the definition of “shoreline” is identical
    for purposes of both statutes, an agency’s interpretation of that
    definition in shoreline certification cases may ultimately impact
    the ability of the public to access certain areas along the sea.
    XI.
    As explained infra, it is axiomatic that the “long-
    standing public use of Hawaii’s beaches . . . has ripened into a
    customary right”, and that accordingly, “public policy . . .
    favors extending public use and ownership to as much of Hawaii’s
    shoreline as is reasonably possible.”        Sotomura, 55 haw. at 
    182, 517 P.2d at 61-62
    .    The decisions of this court regarding the
    location of the shoreline, of which Diamond I is the latest,
    reflect these principles.      Correspondingly, we turn to such
    propositions for guidance in evaluating the instant case.
    In 1968, this court issued Ashford, an opinion by Chief
    Justice Richardson, which set forth many of the foundations
    underlying future shoreline determinations.          Ashford considered
    the location of a property that was described in the royal
    patents as running “ma ke kai,” or “along the 
    sea”. 50 Haw. at 314
    , 440 P.2d at 77.     The appellee contended that the phrase
    described the boundary represented “by the intersection of the
    shore and the horizontal plane of mean high water based on
    publications of the U.S. Coast and Geodetic Survey.”            
    Id. at 77,
    440 P.2d at 314-15.     This court disagreed, instead holding that
    38
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    “me kai kai” was “along the upper reaches of the wash of the
    waves, usually evidenced by the edge of vegetation or by the line
    of debris left by the wash of 
    waves[.]” 50 Haw. at 315
    , 440 P.2d
    at 77.     Ashford also held that the testimony of “[t]wo
    kama#aina[29] witnesses, living in the area of appellees’ land,”
    was relevant to determining the shoreline property boundary.                
    Id. at 316,
    440 P.2d at 77-78.       The shoreline boundary designation
    stated in Ashford as “the upper reaches of the wash of the
    waves,” was later codified in HRS chapter 205A.            1975 Haw. Sess.
    Laws Act 176, § 1 at 386.
    In 1973, in Sotomura, another opinion by Chief Justice
    Richardson, the boundaries of a property were again at 
    issue. 55 Haw. at 178
    . 517 P.2d at 59.        A county surveyor located the
    seaward boundary “between the private upland and public beach” at
    “the upper reaches of the wash of the waves”, which he determined
    was along the debris line, in accordance with Ashford.             Id. at
    
    180, 517 P.2d at 61
    .      The land court agreed.       
    Id. Importantly, Sotomura
    stated that “[t]he Ashford
    decision was a judicial recognition of long-standing public use
    of Hawaii’s beaches to an easily recognizable boundary that has
    ripened into a customary right.”           
    Id. at 181-82,
    517 P.2d at 61
    (citation omitted).      It further established that “[p]ublic
    policy, as interpreted by this court, favors extending to public
    29
    “Kama#aina” can be defined as “[n]ative-born, one born in a place,
    host; native plant; acquainted, familiar.” Pukui & Elbert, Hawaiian
    Dictionary at 124.
    39
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    use and ownership as much of Hawaii’s shoreline as is reasonably
    
    possible.” 55 Haw. at 181
    , 517 P.2d at 61-62 (emphasis added).
    In accordance with these principles, then, Sotomura held as a
    matter of law that “where the wash of the waves is marked by both
    a debris line and a vegetation line lying further mauka[,] the
    presumption is that the upper reaches of the wash of the waves
    over the course of a year lies along the line marking the edge of
    the vegetation growth.”      Id. at 
    182, 517 P.2d at 62
    (emphases
    added).
    This line of cases was extended by Diamond I, which
    further clarified the definition of “shoreline,” first set forth
    in Ashford and currently defined in HRS § 205A-1 and HAR § 13-
    222-2, with respect to shoreline determinations made pursuant to
    HRS § 205A-42.    112 Hawai#i at 
    174, 145 P.3d at 718
    .         The
    shoreline certification at issue in Diamond I was for another
    property in the same subdivision as the property in the instant
    case.   
    Id. at 164,
    145 P.3d at 707.       After a 2002 survey and
    shoreline determination by the BLNR, the plaintiffs in Diamond I
    appealed, and the BLNR entered its “Findings of Fact, Conclusions
    of Law, and Decision and Order” stating, inter alia, as follows:
    63. Naupaka is an ideal indicator of the upper wash of
    the waves because of its salt tolerance and ability to
    withstand occasional salt water inundation, such as
    may be found in storm or other unusually high wave
    conditions, while not surviving if constantly
    inundated or subjected to ripping or undermining by
    wave action.
    . . . .
    78.   The practice of the State Surveyor is to use the
    line of vegetation where present, and not the line of
    debris, as evidence of the upper wash of the waves,
    due to the [sic] greater stability.
    . . . .
    40
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    11.   The edge of the vegetation growth is the best
    evidence of the shoreline in this case . . . as
    against a debris line which may change from week to
    week or from day to day.
    . . . .
    18.   The . . . field survey was correct because,
    among other things: (1) the age of the vegetation
    around the stakes indicated that it was naturally
    rooted and growing; (2) there was no evidence that the
    vegetation was being artificially maintained . . . [.]
    
    Id. at 166-67,
    145 P.3d at 709-10 (emphases added).                The
    contested shoreline certification then expired, a new application
    was filed in 2003, and the BLNR certified the shoreline at the
    same location.         
    Id. at 167,
    145 P.3d at 710.        The plaintiffs
    appealed this proposed certification, and the BLNR filed an Order
    Denying Appeal, that stated, in relevant part,
    Stable vegetation are plants that, without continued
    human intervention, are well-established and would not
    be uprooted, broken off, or unable to survive the
    occasional wash or run-up of waves.
    The fact that at one time the vegetation here
    was planted by human hands does not nullify the use of
    the stable vegetation line to determine the location
    of the shoreline for certification purposes.
    Vegetation that, even though originally induced, is
    able to survive through the seasons over several years
    without human intervention provides a good indication
    of the location of the shoreline.
    
    Id. (emphases added).
    In support of its actions, the BLNR had argued that
    Sotomura indicated that the vegetation line was the more stable
    indicator of the shoreline and thus should be prioritized in all
    cases when making shoreline determinations.               
    Id. at 169,
    145 P.3d
    712
    .        Diamond I disagreed, holding instead that as a matter of
    statutory interpretation, the plain language of HRS § 205A-130
    30
    The last clause in the definition of “shoreline” was at issue in
    Diamond.      112 Hawai#i at 
    171, 145 P.3d at 714
    . To reiterate, HRS § 205A-1
    states:
    (continued...)
    41
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    required that the shoreline should be “certified at the highest
    reach of the highest wash of the waves[,]” whether that was
    indicated by the debris line or the vegetation line.             
    Id. at 173,
    145 P.3d at 716 (emphasis added).         It also held that this
    interpretation was consistent with Sotomura, inasmuch as the
    statement in Sotomura that the vegetation line is a “more
    permanent monument,” supported the Sotomura court’s decision to
    use the vegetation line because it was the furthest mauka.              Id.
    at 
    175, 145 P.3d at 718
    .
    Thus, Diamond I concluded that Sotomura does not
    indicate that the vegetation line will always prevail over the
    debris line.    
    Id. Instead, the
    court in Diamond held that “the
    presumption is that the upper reaches of the wash of the waves
    over the course of a year lies along the line marking the edge of
    the vegetation growth,” if that vegetation line is further mauka
    than the debris line.      
    Id. at 174,
    145 P.3d at 717.
    Diamond I also considered the type of “vegetation
    growth” that can constitute a “vegetation line” for purposes of
    evidencing the shoreline.       Id. at 
    175, 145 P.3d at 718
    .         The
    vegetation at issue in Diamond I was naupaka, the same type of
    30
    (...continued)
    “Shoreline” means the upper reaches of the wash of the
    waves, other than storm and seismic waves, at high
    tide during the season of the year in which the
    highest wash of the waves occurs, usually evidenced by
    the edge of vegetation growth, or the upper limit of
    debris left by the wash of the waves.
    (Emphasis added.)
    42
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    vegetation at issue in the instant case.            
    Id. at 166,
    145 P.3d at
    709.    “Vegetation line” was defined in HAR § 13-222-2, as “‘any
    plant, tree, shrub, grass or groups, clusters, or patches of the
    same, naturally rooted and growing.’”           
    Id. (emphasis in
    original).      In connection with whether the BLNR was correct in
    deciding that artificially induced naupaka could constitute a
    “vegetation line,” this court noted that “‘the agency’s decision
    must be consistent with the legislative purpose[]’” of HRS
    Chapter 205A.      
    Id. (quoting Camara
    v. Agsalud, 
    67 Haw. 212
    , 216,
    
    685 P.2d 794
    , 797 (1984)).
    Diamond I then reviewed the objectives and policies of
    HRS chapter 205A, including “to ‘[p]rotect beaches for public use
    and recreation[,]’” 
    id. (brackets in
    original) (quoting HRS §
    205A-2(b)(9)) and to:
    “(A) Locate new structures inland from the shoreline
    setback to conserve open space, minimize interference
    with natural shoreline processes, and minimize loss of
    improvements due to erosion;
    (B)   Prohibit construction of private, erosion
    protection structures seaward of the shoreline, except
    when they result in improved aesthetic and engineering
    solutions to erosion at the sites and do not interfere
    with existing recreational and waterline
    activities[.]”
    
    Id. (brackets in
    original) (quoting HRS § 205A-2(c)(9)).
    Diamond I concluded that “[t]he utilization of
    artificially planted vegetation in determining the certified
    shoreline encourages private land owners to plant and promote
    salt tolerant vegetation to extend their land further makai[.]”
    Thus, Diamond I held, “[m]erely because artificially planted
    43
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    vegetation survives more than one year does not deem it
    ‘naturally rooted and growing’ such that it can be utilized to
    determine the shoreline.”      
    Id. (emphasis added).
        Diamond I
    overturned the BLNR’s order denying appeal in that case, noting
    that the order had “explicitly rejected the placement of the
    shoreline at the highest wash of the waves during high season[,]”
    and instead located the shoreline at the vegetation line,
    notwithstanding the possibility that a debris line may have been
    more representative of the highest wash of the waves, and the
    fact that the vegetation had been planted and irrigated.            
    Id. at 176,
    145 P.3d at 719.
    XII.
    In Petitioners’ second question, they challenge the
    merits of the BLNR’s shoreline determination decision.            As to
    this question, we conclude that the BLNR’s ultimate shoreline
    determination is invalid because the agency made errors of fact
    and errors of law in its Amended Decision.         The BLNR’s errors of
    law are discussed first.      Under HRS § 91-14(g), conclusions of
    law are reviewable for whether they are in violation of
    constitutional or statutory provisions; are in excess of the
    statutory authority or jurisdiction of the agency; or are
    affected by other error of law.        See Korean Buddhist Dae Won Sa
    Temple of Hawaii v. Sullivan, 87 Hawai#i 217, 229, 
    953 P.2d 1315
    ,
    1327 (1998) (citing HRS § 91-14(g)).
    44
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    A.
    The BLNR’s first error of law was with respect to its
    use of historical evidence.       We conclude that the BLNR must
    consider historical evidence in making its shoreline
    determination.     The BLNR apparently concedes this point, but in
    its first decision did not take into consideration any evidence
    beyond the one year’s wash of the waves.31
    The BLNR failed to properly follow the court’s
    instruction on remand that HRS § 205A-1 does not limit the
    agency’s analysis of the upper reaches of the wash of the waves
    “for only the ‘current’ season . . . .”32         As noted, in its April
    6, 2010 decision on the first appeal, the court stated that
    “[t]he BLNR’s interpretation of HRS § 205A-1, [] that only the
    ‘current’ year’s evidence of the upper reaches of the wash of the
    waves should be considered in determining the shoreline . . .
    conflicts with and/or contradicts the purpose and intent of HRS §
    31
    Although we determined that the appeal from the BLNR’s first
    decision is moot, as 
    observed supra
    , we may consider the BLNR’s first decision
    for purposes of determining the validity of the BLNR’s Amended Decision.
    32
    In COL No. 5 of the BLNR’s Amended Decision, it quotes the
    relevant statute and regulation to define “shoreline” as: “[T]he upper wash of
    the waves, other than storm and seismic waves . . . .” (Emphasis added.) The
    correct definition, in relevant part is that “‘[s]horeline’ means the upper
    reaches of the wash of the waves, other than storm and seismic waves . . . .”
    HRS § 206A-1; HAR § 13-222-2 (emphasis added).
    It is worth noting that the word “reaches” in this context would
    mean “to extend to” or “to get up to or as far as”. Merriam Webster’s
    Collegiate Dictionary 972 (10th ed. 1993). Moreover, “reaches”, in plural,
    suggests more than one wash of the waves, and thereby is consistent with the
    requirement, discussed infra, that the agency consider historical evidence of
    the wash of the waves.
    45
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    205A-1 [].”33    At the oral argument on the second appeal to the
    court, the court discussed with the BLNR’s attorney whether the
    agency had in fact taken into account historical evidence of the
    upper reaches of the wash of the waves.
    THE COURT: Okay. So you would agree with
    [Petitioners’ attorney] then that the certification
    itself lasts for one year, however, the State is not
    restricted to looking at data for that one year period
    only?
    [Counsel for BLNR]:     Oh, yeah --
    THE COURT: You would agree with him?
    [Counsel for BLNR]:     Yeah, I agree that we’re
    not restricted to looking at only that one year period
    and we have not restricted the, you know, the evidence
    that they’ve considered to a one year period, because
    I think even in the surveyor’s report there’s a
    statement that says, you know, the past historical
    data used to -- to indicate the change in condition or
    the conditions of the shoreline, you know, so, it may
    not be used to say, well, the shoreline, you know, was
    here five years ago so it should be here now. But
    it’s used to show how the shoreline is moving in that
    area and what the trends in that area are.
    THE COURT: Then given that position, I would
    assume then that the State would consider 12 years’
    worth of people who live in the area and pictures that
    they’ve taken of the shoreline.
    [Counsel for BLNR]:     They -- we’re not
    disagreeing that that kind of evidence is relevant and
    that it should be looked at. We don’t disagree with
    that. I think the problem is that the evidence that
    was presented in this particular case was not -- was
    not probative because it didn’t -- it didn’t contain,
    I guess enough -- it wasn’t substantial enough.
    (Emphases added.)
    Contrary to what counsel suggested in oral argument,
    the BLNR did not fully consider historical evidence when it made
    33
    As indicated, the BLNR argued before the court on both appeals,
    and to the ICA, that its interpretation of HRS § 205A-1 required that only the
    “current year’s” evidence of the highest wash of the waves be taken into
    account in making a shoreline determination. However, in its Response to this
    court, the BLNR does not argue its earlier interpretation of HRS § 205A-1, but
    rather states that “[t]he ICA properly determined that the ‘BLNR did not
    restrict its analysis of the upper reaches of the waves to the current year,
    but rather took into evaluation all relevant factors present on the
    [p]roperty.’” (Quoting Dobbin, 
    2012 WL 3792024
    , at *5) (internal quotation
    marks and brackets omitted).
    46
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    the findings in its Amended Decision.        Although it removed the
    findings from its initial decision discussing only the “current
    year’s” wash of the waves, the BLNR’s discussion of historical
    evidence in its Amended Decision appears to be a post hoc
    justification of its earlier decision.
    In its first decision, the BLNR adopted the State
    Surveyor’s recommendation in full.        In that decision, the BLNR
    stated that it did not consider historical evidence other than
    the current year’s wash of the waves.        In fact, the BLNR stated
    in its first decision that “given the variable and temporary
    nature of shorelines, [Petitioners’] insistence on solely
    utilizing historical evidence in the determination of a shoreline
    may result in inaccurately locating the upper reaches of the wash
    of the waves in a given year.”       (Emphasis added.)
    However, in its Amended Decision, the BLNR stated that
    the State Surveyor’s initial recommendation from his May 28, 2008
    letter was “based, at least in part, on the Galloway
    [A]pplication . . . [,]” despite the fact that the Galloway
    Application was not mentioned at all in the BLNR’s first
    decision.   If, in fact, the State Surveyor had considered the
    Galloway Application as historical evidence, his recommendation,
    which the BLNR purportedly adopted in its first decision as the
    appropriate shoreline location, would be based on factors that
    were inconsistent with the approach to shoreline certification
    that the BLNR articulated in its first decision.           In other words,
    47
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    in its first decision, the BLNR stated that only the current
    year’s evidence could be considered in making shoreline
    determinations, but in its Amended Decision, it maintained that
    historical evidence had in fact been considered in its first
    decision setting forth the proposed shoreline.
    The Amended Decision also improperly limited its
    consideration of “historical evidence” to the past two winters.
    With respect to the evidence of the Galloway Application, it
    stated that, “[t]he State Surveyor and DLNR staff also noted that
    there was no evidence that the wash of the waves had extended
    that far mauka in the past two winters, especially not during the
    immediately preceding winter season.”        (Emphasis added.)
    However, the court’s decision on the first appeal stated several
    times that Petitioners had observed the shoreline for the past
    eight years.   This statement from the court’s findings, combined
    with the court’s mandate that the BLNR consider more than just
    the “current year’s” evidence of the highest wash of the waves,
    indicates that the court instructed the BLNR to consider all
    historical evidence, rather than just the historical evidence
    that the BLNR felt was appropriate.        Thus, where there was
    evidence of prior years’ “wash of the waves,” the agency must
    consider the evidence from those years when making the shoreline
    determination.
    This comports not only with the instructions of the
    court on remand, but also with this court’s decision in Ashford,
    48
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    which held that “reputation evidence by kama#aina witnesses” must
    be allowed in determining the “public and private boundary
    dividing private land and public beaches.”            
    Ashford, 50 Haw. at 317
    , 145 P.3d at 718.        Thus, the BLNR was wrong when it used only
    the historical evidence from the two preceding winter seasons to
    determine the “highest wash of the waves,” rather than evaluating
    historical evidence of the past eight years for which Petitioners
    provided testimony of their observations.            HRS § 205A-1.     We
    therefore also expressly reject Dobbin and Wagner’s contention
    that “the ultimate determination of the upper reaches of the wash
    of the waves at high tide . . . is [solely] one for experts and
    those qualified under the law.”          This is wrong as a matter of
    law.
    B.
    Second, in the instant case, the BLNR’s Amended
    Decision posits a “multi-variable” approach to shoreline
    certifications, as set forth in the following findings:
    24.   It is the current practice of the DLNR and the
    State Surveyor to use a multi-variable approach to
    determining the location of the upper wash of the
    waves for shoreline certification purposes. The
    multi-variable approach takes into consideration all
    pertinent and appropriate evidentiary factors in a
    shoreline setting, based on the shoreline type (sand
    beach, perched beach, cliff, rocky shoreline, etc., or
    a combination thereof), location (north-, south-,
    east-, or west-facing shore), and exposure to large
    waves (protected within a cover or a bay or by rock
    outcroppings or reefs, or located within the
    protective shadow of other islands, versus exposed to
    the open ocean).
    25.   Some of the evidential variables used by the
    DLNR and State Surveyor include, without limitation,
    debris lines, vegetation lines, wet lines, artificial
    49
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    structures, dune crests, erosion scarps, salt
    deposits, discoloration, and saltwater-dependent
    biota.
    26.   The DLNR and State Surveyor also consider other
    features or facts unique to each shoreline and makes
    appropriate adjustments to the interpretation of the
    evidence as those features or facts are determined by
    the DLNR and State Surveyor to affect the natural
    movement of the wash of the waves within the subject
    shoreline area. Such features and facts include the
    presence and effect of artificially induced vegetation
    or artificially created topographic anomalies that are
    not representative of the overall trends of the
    natural shoreline in the subject shoreline area.
    27.   The DLNR and State Surveyor also incorporate in
    their shoreline determination, any pertinent
    information about the shoreline that is presented by
    the owner of the subject property and any other member
    of the public that has personal knowledge and
    familiarity with the shoreline conditions of the
    subject property during high surf conditions in the
    season of high surf.
    (Emphases added.)
    This multi-variable approach is not described in the
    statute or in the relevant case law.        The approach the BLNR
    should have followed is set out in HRS § 205A-1, defining
    shoreline, and this court’s jurisprudence.         See Diamond I, 112
    Hawai#i at 172-73, 
    145 P.3d 715-16
    (holding that where the
    shoreline is marked by both a vegetation line and a debris line,
    the line further mauka is used to locate the shoreline);
    Sotomura, 55 Haw. at 
    181-82, 517 P.2d at 61
    -62 (locating a ‘high
    water mark’ property boundary at the vegetation line where that
    line was further mauka); 
    Ashford, 50 Haw. at 316
    , 440 P.2d at 78
    (holding that the location of the boundary dividing private land
    from public beaches “was along the upper reaches of the waves as
    represented by the edge of vegetation or the line of debris.”).
    50
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Any factors identified by the BLNR must be consistent with our
    case law, and require that the shoreline be located at the
    debris line or vegetation line, whichever is furthest mauka.
    Diamond I, 112 Hawai#i at 
    172, 145 P.3d at 715
    .          Any approach
    undertaken by the BLNR must be executed in accordance with this
    basic precept.    See 
    id. at 169,
    145 P.3d at 712 (holding that
    “‘the Ashford decision was a judicial recognition of the long-
    standing public use of Hawai#i’s beaches to an easily
    recognizable boundary that has ripened into a customary right[,]”
    and accordingly, the boundary markers for the shoreline must be
    “‘easily recognizable’” and “‘known to the people living thereon
    or in the neighborhood.’”) (emphasis in original) (quoting
    Sotomura, 55 Haw. at 
    181-82, 517 P.2d at 61
    )).
    C.
    1.
    Third, pursuant to Diamond I, “vegetation growth” does
    not include salt-tolerant plants planted on the property for the
    purpose of shoreline demarcation, nor the natural expansion of
    such growth.   112 Hawai#i at 
    175, 145 P.3d at 718
    .          Although in
    this case there is a dispute over the extent to which the plants
    were artificially induced, it is undisputed that salt-tolerant
    plants were in evidence on the property.         However, the BLNR’s
    Amended Decision does not indicate how it considered the presence
    of these salt-tolerant plants in making its decision.            On remand,
    the BLNR must comply with Diamond I’s holding that does not allow
    51
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    the use of salt-tolerant vegetation as an indication of the
    “vegetation line.”      
    Id. 2. Relatedly,
    there is also no indication in the Amended
    Decision of whether the BLNR took artificial barriers into
    consideration.      In Diamond I, this court instructed that one of
    the objectives of HRS chapter 205A was to “‘[p]rohibit
    construction of private erosion-protection structures seaward of
    the shoreline, except when they result in improved aesthetic and
    engineering solutions to erosion at the sites and do not
    interfere with existing recreational and waterline activities.’”
    
    Id. (quoting HRS
    § 205A-2(c)(9)).          Diamond I barred the use of
    artificially induced plants as an indication of the shoreline,
    because the use of such a false vegetation line in making a
    shoreline determination would allow landowners to effectively
    erect an artificial “barrier” extending their land further makai.
    
    Id. This would
    be contrary to the objectives behind HRS chapter
    205A.      Yet, the BLNR’s Amended Decision is bereft of any
    indication of how the policies of HRS § 205A-2(c)(9)34 have been
    enforced, reflecting a disregard of the standards set forth in
    Diamond I, Sotomura, and Ashford.
    34
    HRS § 205A-2 (Supp. 2001) sets forth the objectives and policies
    for the Coastal Zone Management Program. Among these is HRS § 205A-
    2(c)(9)(D), which states that in connection with beach protection, it is a
    policy to “[p]rohibit private property owners from creating a public nuisance
    by inducing or cultivating the private property owner’s vegetation in a beach
    transit corridor.”
    52
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    HAR § 13-222-2 defines “vegetation growth” as “any
    plant, tree, shrub, grass or groups, clusters, or patches of the
    same, naturally rooted and growing.”         (Emphasis added.)      The
    BLNR’s decision did not take this definition, specifically the
    “naturally rooted and growing” portion, into consideration when
    it decided the naupaka and other plants could be used as an
    indicator of the shoreline.       Both sides submitted evidence on
    this issue, and at FOF No. 69, the BLNR concluded that “Appellees
    Dobbin and Wagner’s Opening Brief [sic] [to the BLNR] refuted the
    assertions that the vegetation growing along the shoreline was
    planted and ‘induced’ with the aid of irrigation.”
    But, there was no support for this finding.           The BLNR
    cited to Dobbin and Wagner’s Answering Brief, which stated only
    that the sprinklers located on the property were not “aimed
    towards nor intended to irrigate the naturally growing shoreline
    vegetation.”35    However, in order to determine whether the
    vegetation was “naturally rooted and growing” in accordance with
    the HAR § 13-222-2 definition, the BLNR must determine that the
    shoreline vegetation was actually “naturally growing”, which
    requires more than a conclusion that the sprinklers were not
    “aimed at or intended to irrigate” the vegetation.            If the
    sprinklers’ action actually resulted in watering the vegetation
    as a result of the wind or other natural factors, then it is of
    35
    There was also some inconsistency between the affidavits provided
    by Respondents regarding the location of the sprinklers.
    53
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    no import whether the sprinklers were not “intended to irrigate”
    the vegetation.
    3.
    Moreover, in this case, the BLNR Amended Decision
    states only that the State Surveyor and DLNR considered “the
    presence and effect of artificially induced vegetation or
    artificially created topographic anomalies[.]”          It is not evident
    from the decision how the presence of potentially artificial
    barriers affected the BLNR’s determination of the “highest wash
    of the waves.”    HRS § 205A-1.     See Kilauea Neighborhood Ass’n v.
    Land Use Comm’n., 
    7 Haw. App. 227
    , 230, 
    751 P.2d 1031
    , 1034
    (1988) (“An agency’s findings must be sufficient to allow the
    reviewing court to track the steps by which the agency reached
    its decision.”); In re Water Use Permit Applications, 105 Hawai#i
    1, 27, 
    93 P.3d 643
    , 669 (2004) (Acoba, J., concurring) (“The
    purpose behind findings is to assure reasoned decision making by
    the agency and enable judicial review of agency decisions.”
    (internal quotation marks and citations omitted)).
    Additionally, the BLNR’s Amended Decision locates the
    shoreline at “the makai edge of the hedge.”          According to the
    BLNR’s finding 36(e), this is the area where naupaka and beach
    heliotrope are located, along with debris.         Diamond I mandates
    that, as between the debris and the vegetation line, the
    shoreline must be located at the line that is further mauka.               112
    Hawai#i at 
    174-75, 145 P.3d at 717-18
    .        The Amended Decision
    54
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    states at finding 61 that, “[Petitioners] argued that the use of
    naupaka or other salt tolerant plants to create an artificial
    shoreline prevents or hinders the observation of the true
    evidence of the debris line created by the upper wash of the
    winter waves.”    Petitioner Diamond’s Declaration also states that
    “[a]t the site visit on April 18, 2008, I pointed out the current
    condition of the naupaka as obvious evidence that the highest
    wash of waves had in fact washed through and into the planted
    vegetation.”
    However, in its Amended Decision, the BLNR seemingly
    did not take into account whether the debris line was located at
    the same place as the vegetation line because the debris line
    was, as Petitioners suggest, being hindered by the presence of
    salt-tolerant vegetation.      Although the Amended Decision suggests
    that debris is located in the vegetation, it included no findings
    as to whether the vegetation line or the debris line is located
    further mauka.    It would be contrary to Diamond, the policy
    articulated in Sotomura, and the legislative purpose behind HRS
    chapter 205A, as 
    noted supra
    , to locate the shoreline where salt-
    tolerant plants had been grown and had prevented a debris line
    from forming that was indicative of the true “highest wash of the
    waves.”
    D.
    Fourth, the BLNR apparently disregarded the Wichman
    testimony submitted by Petitioners, on the basis that first, it
    55
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    “was not in the form of an affidavit or declaration,” second, it
    “was not attested to by anyone nor was any context for the
    document provided by [Petitioners],” and third, that “[i]t is not
    clear from the document or [Petitioners’] Opening Brief [to the
    BLNR] whether the person who allegedly authored the document is
    an expert or what his expertise might be, if any.”           The BLNR’s
    disregard for this testimony is manifestly contrary to HRS
    chapter 91.
    A shoreline determination is a contested case hearing.
    See Diamond I, 112 Hawai#i at 
    165, 145 P.3d at 708
    .           With respect
    to evidence adduced in contested case hearings, HRS § 91-10
    (Supp. 2003) provides in relevant part that:
    In contested cases:
    (1) Except as provided in section 91-8.5[ 36], any oral or
    documentary evidence may be received, but every agency shall
    as a matter of policy provide for the exclusion of
    irrelevant, immaterial, or unduly repetitious evidence and
    no sanction shall be imposed or rule or order be issued
    except upon consideration of the whole record or such
    portions thereof as may be cited by any party and as
    supported by and in accordance with the reliable, probative,
    and substantial evidence.
    (Emphases added.)    The BLNR made an implicit finding that the
    Wichman testimony was not reliable, apparently because of the
    format of the document.     But it is elemental that contested case
    hearings do not require that evidence presented to the BLNR must
    be in the form of an affidavit or declaration, or “attested to.”
    Instead, under the statute, “any oral or documentary evidence may
    36
    HRS § 91-8.5 (Supp. 2003) is not relevant to this case.
    56
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    be received” unless such evidence is “irrelevant, immaterial, or
    unduly repetitious”.      HRS § 91-10.     There is nothing in the
    record to indicate that the Wichman testimony was “irrelevant,
    immaterial, or unduly repetitious.”         The BLNR erred as a matter
    of law in entirely disregarding the testimony.
    Additionally, the BLNR’s findings of fact with respect
    to Wichman’s testimony are clearly erroneous.           The BLNR states
    that “it is not clear . . . whether the person who allegedly
    authored the document is an expert or what his expertise might
    be, if any.”    First, it would not necessarily matter whether
    Wichman was an expert.37      Pursuant to this court’s decision in
    Ashford, the testimony of kama#aina witness is relevant in
    locating the shoreline, and Wichman stated that “[a]ll [his] life
    [he] has been an active surfer, diver and fisherman and know[s]
    [sic] the ocean and beaches here in Ha#ena and Wainiha very
    well.”
    Second, the Wichman testimony states that he has worked
    for the National Tropical Botanical Garden since 1976, and is the
    director of the Limahuli Garden and Preserve.           Under these
    circumstances, the BLNR’s outright dismissal of the Wichman
    37
    In the BLNR’s first decision, its findings state that “[w]hile Mr.
    Wichman’s testimony appears to be presented as expert testimony regarding
    vegetation, there is no evidence that he is qualified to testify as an expert
    on such features as the ‘highest wash of the waves’ that are determined by
    coastal geology or ocean dynamics.” The BLNR gives no indication of why the
    Wichman testimony could no longer be deemed “expert testimony” when it made
    its Amended Decision. Thus, the notion that Wichman’s testimony was not
    “expert” appears to be a post hoc justification to disregard that testimony
    altogether.
    57
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    testimony, because “[i]t is not clear . . .          whether the person
    who allegedly authored the document is an expert or what his
    expertise might be, if any[,]” is not only clearly erroneous, but
    manifestly wrong as a matter of law.        See 
    Ashford, 50 Haw. at 316
    , 440 P.2d at 77 (holding that “Hawaii’s land laws are unique
    in that they are based on ancient tradition, custom, practice,
    and usage[,]” and therefore, reputation evidence by kama#aina
    witnesses may be used in land disputes).
    XIII.
    A.
    The ICA also erred in vacating the court’s decision and
    affirming the BLNR’s Amended Decision because, as the court
    observed, many of the agency’s findings of fact were clearly
    erroneous in view of the reliable, probative, and substantial
    evidence in the whole record.       See HRS 91-14(g)(5).      A finding of
    fact is “clearly erroneous” when “‘(1) the record lacks
    substantial evidence to support the finding or determination, or
    (2) despite substantial evidence to support the finding or
    determination, the appellate court is left with the definite and
    firm conviction that a mistake has been made.’”           Del Monte Fresh
    Produce, Inc. v. Int’l Longshore & Warehouse Union, Local 142,
    112 Hawai#i 489, 499, 
    146 P.3d 1066
    , 1076 (2006) (quoting In re
    Water Use Permit Applications, 94 Hawai#i 97, 119, 
    9 P.3d 409
    ,
    431 (2000)).   To determine whether evidence is substantial
    evidence, it must be “credible evidence which is of sufficient
    58
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    quality and probative value to enable a person of reasonable
    caution to support a conclusion.”        
    Id. (internal quotation
    marks
    and ciatations omitted).
    B.
    In the instant case, the BLNR made a number of clearly
    erroneous findings with respect to Petitioners’ declarations and
    the attached photographs.      Findings 48 through 56, discussing the
    evidence presented by Petitioners, are incorrect and/or
    inconsistent and thus undermine the final determination by the
    BLNR.   First, finding 52 stated that “[the Blair declaration] did
    not contain any information as to the dates when specific
    photographs were taken or who took the photographs.”            This is
    clearly erroneous in light of the Blair declaration, which
    stated, inter alia, that “[t]he photograph attached hereto as
    Exhibit ‘E’ was taken on October 19, 2005, and shows Chris L.
    Conger identifying the location of the shoreline as recommended
    by the State Surveyor on October 19, 2005.”          (Emphasis added.)
    The BLNR’s finding 51 stated that “it is not possible to
    ascertain from [the Blair declaration] what was the object of the
    specific photographs or what they were purported to portray.
    (Emphasis added.)    To the contrary, the Blair declaration stated
    that “the photographs attached hereto as Exhibits ‘G’ through ‘N’
    are true and correct copies, and accurately show the upper
    reaches of the waves . . . on the Dobbin property.”
    59
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    At finding 48, the BLNR states that “[t]he photographs
    contained in Exhibits G through N of [Petitioners’] Opening Brief
    are date stamped, either on the photos or in the captions, with
    dates falling between 2004 and 2008.”        (Emphasis added.)      But, in
    contradiction of finding 48, at finding 53, the BLNR stated that
    “[w]ithout having made any reference to specific observations as
    to the location of the highest wash of the waves, [Petitioner]
    Blair testified that . . . the shoreline should be located twenty
    feet mauka of the proposed shoreline,” and at finding 56, it
    stated that “[the Blair Declaration] and [the Diamond
    Declaration] do not clearly identify what each photograph is
    purported to depict.”     (Emphases added.)      These last two
    observations are inaccurate in light of the fact that the
    photographs, some dated, were also attached to the briefs as
    exhibits, and in light of the actual Blair Declaration that
    provided some specifics as to what the photos depict and what
    locations were relevant.      Based on these errors in considering
    the points discussed by Petitioners in their declarations, it is
    obvious that “the record lacks substantial evidence” to support
    these findings.    The BLNR apparently rejected altogether
    Petitioners’ evidence of the location of the shoreline, thereby
    ignoring substantial historical evidence of the shoreline’s
    location.
    XIV.
    Finally, the BLNR’s Amended Decision reflects an abuse
    60
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    of discretion because it arbitrarily and capriciously failed to
    follow the instructions of the court on remand from its earlier
    decision.    Pursuant to HRS § 91-14(g)(6), an agency’s exercise of
    discretion is reviewable as to whether it is “[a]rbitary, or
    capricious, or characterized by an abuse of discretion or clearly
    unwarranted exercise of discretion.”          See Sullivan, 87 Hawai#i at
    
    228, 953 P.2d at 1326
    .       In the instant case, the BLNR failed to
    follow the proper instructions of the court on remand with
    respect to its Amended Decision.
    At oral argument before the court on the second appeal,
    the following colloquy took place between the court and the
    attorney for the BLNR:
    [Counsel for BLNR]:     Exactly. What it was
    [the BLNR was] taking, based on the [c]ourt’s, you
    know, findings and the directions from this [c]ourt,
    they were taking a new hard look at the evidence that
    was actually presented in the initial case.
    THE COURT: As opposed to what kind of look that
    was initially taken?
    [Counsel for BLNR]:     I mean, they did take
    it. I mean, they did consider it. You know, it was
    this [c]ourt that disagreed with their
    characterization of the evidence, so they looked at it
    again, and --
    THE COURT: Ms. Chow, let me just, I want to
    make sure that I’m absolutely clear on this point.
    Okay.
    Upon remand, this [c]ourt stated that the matter
    is remanded to the BLNR with specific instructions to
    appropriately consider and give due weight to
    [Petitioners’] proposed evidence and to correctly
    apply applicable statutes, case law and Administrative
    Rules.
    You’re saying the consideration and the weight
    that was given the second go round is the same as it
    was given the first go round?
    [Counsel for BLNR]:     Well, it was -- that
    could very well be because, you know, the board
    believes it gave appropriate weight to the evidence
    during the first go round. The evidence didn’t change
    between the first decision and the second decision.
    61
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    THE COURT: So this [c]ourt’s decision finding
    otherwise, and this [c]ourt’s instructions sending the
    matter back to the BLNR, really had no significant
    effect on the BLNR?
    [Counsel for BLNR]:     They did take a relook -
    - they did relook at all of the evidence and, you
    know, to see, you know, was there something there that
    was not considered the first time or, you know, how
    could they better support their, you know, decision.
    How was it -- would their decision be supported. And
    they, you know, made the amended findings and
    decision.
    (Emphases added.)
    With respect to its Amended Decision, first, the BLNR
    did not address the court’s conclusion in its decision on the
    first appeal that “the current certified shoreline appears to
    incorrectly allow for the manipulation of the shoreline based
    upon artificially induced and enhanced vegetation, not in
    accordance with HRS § 205A-1.”        Although the BLNR discussed how
    it weighed Petitioners’ evidence in its findings with respect to
    whether the shoreline was artificially created, it arbitrarily
    failed to indicate how it weighed Respondents Dobbin and Wagner’s
    evidence.
    Instead, in its Amended Decision, the BLNR simply
    recounted Respondents Dobbin and Wagner’s evidence at findings 69
    through 75.    For example, on the issue of whether the sprinkler
    heads were aimed at the shoreline vegetation or toward the mauka
    portion of the property, the BLNR did not explain how it found
    that the Moody Affidavit, stating that “to the best of [Moody’s]
    recollection, all the sprinkler heads on [the line closest to the
    62
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    shoreline] were aimed in such a fashion that the spray pattern
    would be parallel to or away from the shoreline[,]” was more
    persuasive than Petitioner Diamond’s declaration or photographs.
    Instead, finding 72 states only that “Steve Moody, the owner of
    the [] property from 2000 to 2004, admitted to having an
    irrigation system [on] the property, but he testified that the
    system was located several feet away from the edge of the naupaka
    growing along the shoreline and that all of the sprinkler heads
    were aimed so the spray would be parallel to or away from the
    shoreline.”
    Additionally, the declarations of current and former
    owners provided by Dobbin and Wagner do not include any testimony
    with respect to where they saw the highest wash of the waves on
    the property.   Thus, the only substantial evidence of a
    historical nature, see Ashford, 50 Haw. at 
    315, 440 P.2d at 77
    ,
    were the years of observations described in the declarations of
    Diamond, Blair, and Robeson, and the record fails in any way to
    controvert Petitioners’ historical evidence.
    XV.
    Based on the foregoing, the ICA’s August 31, 2012
    Memorandum Opinion is vacated in part, the court’s March 31, 2011
    decision is vacated in part, the May 21, 2010 Amended Decision of
    the BLNR is vacated, and the case is remanded to the court with
    63
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    instructions to remand the case to the BLNR for proceedings
    consistent with this opinion.
