    SUSAN COHEN v. DEPARTMENT OF ENERGY AND
    ENVIRONMENTAL PROTECTION ET AL.
    (AC 44547)
    (AC 44551)
    Elgo, Suarez and Lavine, Js.
    Syllabus
    The plaintiff homeowner and the intervening plaintiffs, the town of Green-
    wich and its harbor management commission, appealed to this court
    from the judgment of the Superior Court dismissing the plaintiff’s admin-
    istrative appeal from the final decision of the deputy commissioner of
    the named defendant, the Department of Energy and Environmental
    Protection, granting an application to construct a residential dock adja-
    cent to the plaintiff’s waterfront property. In their application, the defen-
    dants M and A proposed to construct the dock on a lot they owned that
    consisted of tidal wetlands fronting Greenwich Cove and bordering the
    plaintiff’s residence. The plaintiff sought to intervene in the proceedings
    before the department pursuant to the applicable statute (§ 22a-19) and
    regulation (§ 22a-3a-6 (k)) to oppose M and A’s application. A department
    hearing officer concluded that the plaintiff lacked standing to intervene
    under § 22a-3a-6 (k) of the regulations but granted her intervenor status
    under § 22a-19 to pursue her claim of visual degradation to her property
    and environmental harm that she alleged would be caused by the pro-
    posed dock. At a hearing the department conducted to receive public
    comment on M and A’s application, the commission submitted a letter,
    stating, inter alia, that it could not make a favorable recommendation
    concerning the application and that, pursuant to statute (§ 22a-113n),
    recommendations made by the commission consistent with the town’s
    harbor management plan are binding on state officials when making
    regulatory decisions. The hearing officer issued a proposed final decision
    recommending approval of M and A’s application. The hearing officer
    determined that the commission’s comment letter did not constitute
    substantive evidence and that the department was not bound by its
    recommendation. The hearing officer further determined that the only
    recommendations contemplated by § 22a-113n (b) are those contained
    in a harbor management plan that has been adopted by a harbor manage-
    ment commission and approved by the department pursuant to statute
    (§ 22a-113m). The hearing officer concluded that nothing in the town’s
    harbor management plan prevented him from recommending to the
    department that M and A’s application be approved. Finally, the hearing
    officer concluded that the plaintiff had failed to satisfy her burden
    of proving that the proposed dock was reasonably likely to have an
    unreasonable environmental impact on nearby viewpoints and vistas or
    that it would result in other environmental harm. The deputy commis-
    sioner thereafter adopted the hearing officer’s proposed decision. On
    appeal to the Superior Court, the intervenors and the plaintiff claimed,
    inter alia, that the deputy commissioner improperly concluded that
    § 22a-113n did not authorize the commission to make recommendations
    that are binding on the department. The court rendered judgment dis-
    missing the appeals, concluding, inter alia, that the deputy commission-
    er’s final decision was supported by substantial evidence and that she
    had properly allocated the burdens of proof between the plaintiff and
    M and A. The court further upheld the deputy commissioner’s determina-
    tion that § 22a-113n empowers harbor management commissions to
    make recommendations that are binding on the department only when
    such recommendations arise from content already included in an
    approved harbor management plan. Held:
    1. The intervening plaintiffs could not prevail on their claim that the Superior
    Court incorrectly concluded that § 22a-113n did not authorize the com-
    mission to make recommendations that were binding on the department
    concerning dock permit applications within the commission’s jurisdic-
    tion:
    a. Contrary to M and A’s assertion that the intervenors’ claim was not
    properly before this court because it was derivative of the same claim
    brought by the plaintiff, the intervenors’ standing was not dependent on
    the plaintiff’s standing to bring the same claim, § 22a-113n (b) having
    provided the intervenors with an independent jurisdictional basis to
    pursue their claim, as § 22a-113n (b) implicated their authority to make
    recommendations to state and local officials concerning activities affect-
    ing harbor areas within the intervenors’ jurisdiction; moreover, the inter-
    venors’ assertion in their motion to intervene that the deputy commission-
    er’s decision could have far-reaching consequences for them with regard
    to any application, including future dock applications, that require a
    permit from the department, was precisely the sort of concrete, particu-
    larized allegation sufficient to raise a colorable claim of injury; further-
    more, dismissal of the intervenors’ claim would require them to adjudi-
    cate the claim in another forum, which would be redundant and result
    in unnecessary delay and a waste of judicial resources in light of the
    rulings issued by the deputy commissioner and the Superior Court con-
    cerning the proper construction of § 22a-113n.
    b. This court was not persuaded by M and A’s contention that it should
    refuse to adjudicate the proper construction of § 22a-113n, which was
    based on their claim that the issue of whether a harbor management
    commission’s recommendation is binding on the department was never
    properly raised in the administrative proceedings; although the commis-
    sion’s comment letter was not evidence to be considered in determining
    whether to grant M and A’s application, the commission having elected
    not to appear in the administrative proceedings and submit written testi-
    mony pursuant to statute (§ 22a-99), the nature of the intervenors’ partici-
    pation before the Superior Court substantially differed from their involve-
    ment before the department such that the issue concerning the proper
    interpretation of § 22a-113n was properly before this court.
    2. The intervenors could not prevail on their claim that § 22a-113n granted
    the commission the authority to make recommendations that are binding
    on the department concerning individual dock placements within the
    commission’s jurisdiction: the plain text of § 22a-113n authorizes harbor
    management commissions to make such recommendations only when
    they arise from content already included in an approved harbor manage-
    ment plan, and the Greenwich Harbor Management Plan did not discuss
    the permitting or placement of individual docks; moreover, the relation-
    ship of § 22a-113n to other statutes within the regulatory framework
    constrained the department’s authority to issue individual permits for
    docks in areas designated as unsuitable in harbor management plans,
    which are subject to the department’s annual review; furthermore, the
    lack of broad veto power on the part of harbor management commissions
    over individual dock permits does not render the plain text of § 22a-
    113n unworkable, as harbor management commissions are permitted
    to set forth criteria concerning individual dock placement that become
    binding on the department once a harbor management plan is approved.
    3. The plaintiff could not prevail on her claims that the hearing officer
    incorrectly allocated the burdens of proof between her and M and A
    during the administrative hearing, and that the Superior Court incor-
    rectly concluded that substantial evidence supported the deputy com-
    missioner’s determination that there were no feasible and prudent alter-
    natives to the dock proposed by M and A:
    a. This court declined to review the plaintiff’s claim that the Superior
    Court’s determination that she had demonstrated classical aggrievement
    overruled, sub silentio, the hearing officer’s determination that she had
    failed to demonstrate standing to intervene pursuant to § 22a-3a-6 (k)
    (1) (B) of the regulations; although the plaintiff contended that the
    hearing officer incorrectly applied to her the burden of proof for environ-
    mental intervenors set forth in § 22a-19 when she should not have been
    required to resort to § 22a-19 as a basis for intervention, she never
    properly raised in the Superior Court the issue of her standing pursuant
    to § 22a-3a-6 (k) (1) (B), her argument on appeal confused the hearing
    officer’s determination concerning her standing with the court’s determi-
    nation that she established aggrievement sufficient to invoke the court’s
    subject matter jurisdiction, and the plaintiff pleaded different factual
    allegations in her complaint to the Superior Court than she did in her
    motion to intervene before the hearing officer.
    b. The plaintiff’s claim that the hearing officer incorrectly placed the
    burden of proof on her to show that there were feasible alternatives to
    the proposed dock was unavailing, as she failed to understand that
    properly alleging standing under § 22a-19 (a) to be made a party to an
    administrative proceeding requires a showing of only a colorable claim
    of environmental harm, whereas an intervenor already joined in the
    litigation is required to produce evidence of unreasonable environmental
    impairment before the department is required to consider feasible alter-
    natives under § 22a-19 (b); moreover, the court did not determine that
    M and A had the burden of showing the absence of feasible alternatives
    to the proposed dock only if the plaintiff made a prima facie showing
    of environmental harm under § 22a-19, as there was no requirement that
    M and A show the absence of, or that the department consider, feasible
    alternatives to the dock in light of the plaintiff’s failure to set forth
    substantial evidence that the dock would or was reasonably likely to
    cause unreasonable environmental harm.
    c. The court properly concluded that there was substantial evidence in
    the record to support the hearing officer’s determination that there were
    no feasible and prudent alternatives to the proposed dock; the hearing
    officer noted that department staff had considered and rejected fourteen
    alternative designs to the structure before ultimately concluding that
    the approved structure would have the least adverse impact on the
    surrounding tidal wetlands, and, although the plaintiff presented expert
    testimony that the proposed dock would negatively impact the sur-
    rounding wetlands, the hearing officer acted within his discretion in
    crediting expert testimony presented by the department and M and A that
    the proposed structure would have minimal impact on the tidal wetlands.

    Opinion
    SUAREZ, J. In these related appeals, the plaintiff,
    Susan Cohen, in Docket No. AC 44547, and the interven-
    ing plaintiffs, the Harbor Management Commission of
    the Town of Greenwich (commission) and the town of
    Greenwich (town), in Docket No. AC 44551, appeal
    from the judgment of the Superior Court dismissing the
    plaintiff’s administrative appeal from the final decision
    of the Deputy Commissioner of Energy and Environ-
    mental Protection (deputy commissioner) granting the
    application of the defendants Mark Marache and Marti
    Marache to construct a residential dock and pier. On
    appeal, both the plaintiff and the intervening plaintiffs
    claim that the court improperly concluded that General
    Statutes § 22a-113n did not authorize the commission to
    make recommendations that are binding on the named
    defendant, the Department of Energy and Environmen-
    tal Protection (department),1 regarding applications for
    dock permits within the commission’s jurisdiction. The
    plaintiff also claims that the court incorrectly deter-
    mined (1) that the department applied the correct bur-
    dens of proof during the parties’ administrative hearing,
    and (2) that there was substantial evidence in the record
    to support the department’s determination that there
    were no feasible and prudent alternatives that would
    reduce the proposed dock’s environmental impact. We
    affirm the judgment of the Superior Court.
    The record reveals the following facts, which the
    department found or which are undisputed, and proce-
    dural history. The plaintiff and the defendants own
    neighboring properties in the Riverside district of
    Greenwich. The plaintiff resides at 7 Perkely Lane and
    the defendants reside at 12 Perkely Lane. In addition
    to their principal residence, which is located on the
    west side of Perkely Lane, the defendants also own an
    undeveloped lot on the easterly side of the road (subject
    property), located at 15 Perkely Lane, which fronts
    Greenwich Cove and borders the plaintiff’s residence
    to the north. The subject property is ‘‘made up of two
    bands of tidal wetlands, a band of ‘low marsh’ below
    [the median high water line] and along the edge of
    Greenwich Cove, and a band of ‘high marsh’ just inland
    of the low marsh, extending approximately to [the
    median high water line].’’ Perkely Lane is situated
    within a heavily developed section of Greenwich Cove
    where many waterfront homes, including the plaintiff’s
    residence, are improved by docks and other man-made
    structures.
    On April 14, 2015, the defendants, pursuant to the
    Structures, Dredging and Fill Act of 1939, General Stat-
    utes § 22a-359 et seq. (structures, dredging and fill act);
    the Tidal Wetlands Act of 1969 (tidal wetlands act),
    General Statutes § 22a-28 et seq.; the Coastal Manage-
    ment Act of 1980 (coastal management act), General
    Statutes § 22a-90 et seq.; and attendant state regula-
    tions, Regs., Conn. State Agencies § 22a-30-1 et seq.;
    submitted to the department an application for permis-
    sion to construct a residential dock and boat lift (pro-
    posed structure) on the subject property.2 The defen-
    dants’ application proposed that the structure be
    located six inches waterward of the mean high water
    line,3 in an effort to comply with a town zoning ordi-
    nance.4 In addition, the defendants intended to access
    the proposed dock by walking through the tidal wet-
    lands on the subject property to reach an access ladder
    leading to a pier. See footnote 2 of this opinion. On
    March 6, 2018, the department issued a tentative deter-
    mination to approve the application, with notice of the
    tentative determination published in the Greenwich
    Time, and a draft permit was prepared.5
    On March 26, 2018, the plaintiff’s husband, Bruce F.
    Cohen, acting pursuant to General Statutes §§ 22a-326
    and 22a-361 (b),7 submitted to the department a petition
    for a public hearing on the defendants’ application.8
    Notice of the hearing was published in the Greenwich
    Time on August 12, 2018.
    On June 6, 2018, the plaintiff filed a ‘‘Verified Petition
    and Notice of Intervention,’’ pursuant to § 22a-3a-6 (k)
    (1) (B) of the Regulations of Connecticut State Agen-
    cies9 and General Statutes § 22a-1910 of the Connecticut
    Environmental Protection Act of 1971 (CEPA), General
    Statutes § 22a-14 et seq., seeking status as an interven-
    ing party in the defendants’ application that was pro-
    ceeding before the department. Under § 22a-3a-6 (k) of
    the regulations, the plaintiff alleged, inter alia, that the
    erection and maintenance of the proposed structure
    would ‘‘have a significant adverse impact on the visual
    character and value of [her] home’’ and that permitting
    the defendants to ‘‘evade local zoning restrictions’’ by
    situating their dock ‘‘outside of local regulatory jurisdic-
    tion’’ would ‘‘establish a precedent that will have impact
    on the [plaintiff] because of similar conditions existing
    in the nearby . . . neighborhood.’’
    Under § 22a-19, which bestows statutory standing on
    intervening parties alleging that a proposed permit
    ‘‘involves conduct which has, or which is reasonably
    likely to have, the effect of unreasonably polluting,
    impairing or destroying the public trust in the air, water
    or other natural resources of the state’’; see General
    Statutes § 22a-19 (a) (1); the plaintiff alleged, inter alia,
    that the proposed dock would (1) run contrary to the
    department’s policy ‘‘ ‘to preserve the wetlands and to
    prevent the despoliation and destruction thereof’ ’’; (2)
    ‘‘degrade visual quality through a significant alteration
    of the natural features of the tidal wetland in which
    [the dock] is proposed to be located’’; and (3) ‘‘lead
    to a proliferation of permit applications for docks in
    inappropriate locations, thereby impacting in a signifi-
    cant manner other and more extensive natural
    resources such as tidal wetlands.’’ The defendants filed
    an objection on June 13, 2018.
    On July 9, 2018, a department hearing officer issued
    a ruling on the ‘‘Verified Petition and Notice of Interven-
    tion,’’ granting the plaintiff intervening party status as
    to one allegation, made pursuant to § 22a-19, concern-
    ing the visual impact of the proposed structure, and
    denying intervening party status on all other grounds
    alleged. With regard to the plaintiff’s claims under § 22a-
    3a-6 (k) of the regulations, the hearing officer stated
    that a proposed intervening party must demonstrate
    that her ‘‘legal rights, duties or privileges will or may
    reasonably be expected to be affected by the decision
    in the proceeding.’’ (Internal quotation marks omitted.)
    The hearing officer then clarified that, although that
    standard ‘‘is not identical to the ‘classical aggrievement’
    standard employed by our courts, judicial analysis of
    that standard is instructive when defining what consti-
    tutes a legal right, duty or privilege.’’ Applying the classi-
    cal aggrievement analysis set forth in our Supreme
    Court’s decision in Canty v. Otto, 
    304 Conn. 546
    , 557,
    
    41 A.3d 280
     (2012), the hearing officer concluded that
    the plaintiff’s first allegation, regarding the proposed
    structure’s potential to visually impact and, thereby,
    affect the economic value of her residence, ‘‘lack[ed]
    specific facts to demonstrate how that damage will
    occur.’’ The hearing officer also determined that the
    ‘‘second and third allegations, regarding an alleged
    [department] policy about the interface between coastal
    structures and local zoning, are not personal but,
    instead, are general interests shared by all members of
    the community.’’ The hearing officer concluded, accord-
    ingly, that the plaintiff did not have standing to inter-
    vene under § 22a-3a-6 (k) of the regulations.
    With regard to the plaintiff’s environmental claims
    under § 22a-19, the hearing officer clarified that
    intervening parties must make specific, factual allega-
    tions that set forth the nature of the alleged unreason-
    able pollution, impairment, or destruction of the public
    trust in the air, water or other natural resources of
    the state. Applying that standard, the hearing officer
    determined that the plaintiff’s first and third claims,
    which alleged that the proposed dock would despoil
    and destroy ‘‘the tidal wetland of Long Meadow Creek’’
    and lead to ‘‘a proliferation of permit applications for
    docks in inappropriate locations,’’ were not pleaded
    with sufficient specificity to confer on her statutory
    standing pursuant to § 22a-19.11 By contrast, the hearing
    officer concluded that the plaintiff’s second claim,
    which alleged that the proposed dock structure will
    degrade the visual quality of the tidal wetlands through
    a significant alteration of its natural features, was suffi-
    cient to grant intervening party status. Specifically, the
    hearing officer determined that ‘‘the allegation alleges
    an environmental harm implicated in a review pursuant
    to the coastal management act and indicates the likeli-
    ness that the harm will occur . . . .’’ Accordingly, the
    hearing officer granted the plaintiff standing as an
    intervening party only as to her second allegation of
    environmental harm.
    On August 13, 2018, the plaintiff filed a motion for
    reconsideration regarding the hearing officer’s ruling
    on her ‘‘Verified Petition and Notice of Intervention,’’
    seeking to expand the scope of her participation as an
    intervening party. In support of her motion, the plaintiff
    submitted to the hearing officer an affidavit from Wil-
    liam L. Kenny, a certified professional wetlands scien-
    tist, which detailed ‘‘potential impacts to tidal wetlands
    from pedestrian access to the dock and the operation
    of a motorboat in the proximity of a dock.’’ On Septem-
    ber 17, 2018, the hearing officer granted the plaintiff’s
    motion for reconsideration, thereby expanding the
    scope of her intervening party status under § 22a-19
    to include ‘‘issues of unreasonabl[e] impacts to tidal
    wetlands from pedestrian access to the proposed struc-
    ture and operation of a motorboat in the vicinity of the
    structure.’’ The hearing officer clarified, however, that
    the plaintiff’s standing to intervene in the application
    proceeding was strictly limited to the specific environ-
    mental allegations ‘‘identified in this ruling and in the
    July 9, 2018 ruling.’’
    On September 13, 2018, the department held a hearing
    to receive public comment at Greenwich Town Hall.12
    Although General Statutes § 22a-99 entitled the commis-
    sion to submit written testimony to the department and
    ‘‘appear by right as a party to any hearing before [the
    department] concerning any permit or license to be
    issued . . . for an activity occurring within the coastal
    boundary of the municipality,’’ the commission chose
    neither to submit written testimony nor to intervene as
    a party to the proceeding.
    On September 21, 2018, the commission submitted
    to the department a written comment letter (comment
    letter) that set forth findings and recommendations con-
    cerning the defendants’ application. Specifically, the
    commission voiced concerns regarding the ‘‘precedent-
    setting implications and potential environmental
    impacts of [the proposed structure] and similar propos-
    als,’’ as well as the proposed structure’s compliance
    with town zoning regulations. In addition, the commis-
    sion argued, pursuant to § 22a-113n, that recommenda-
    tions made by the commission ‘‘consistent with and
    adequately supported by’’ the town’s Harbor Manage-
    ment Plan (plan) are ‘‘binding on any official of the
    state of Connecticut when making regulatory decisions
    . . . affecting [the Greenwich Harbors Area], unless
    such official shows cause why a different action should
    be taken.’’ Accordingly, the commission concluded:
    ‘‘[The commission] is not able to make a favorable rec-
    ommendation concerning the proposed project absent
    an understanding of the [department’s] policy concern-
    ing state review and approval of proposed water-access
    structures located entirely in the [p]ublic [t]rust [a]rea
    waterward of the [median high water] line and affecting
    tidal wetlands and other coastal resources. The [com-
    mission] therefore formally recommends that the
    [department] provide such a policy statement to be
    considered in the ongoing public hearing process and
    any subsequent appeals. In addition, the [commission]
    is concerned that the policies of [the plan] were not
    considered by the [department] in the application
    review process, which it is obliged to do, and formally
    recommends that such consideration now be given in
    the ongoing public hearing process and any subsequent
    appeals.’’
    On September 24, 2018, the department held an evi-
    dentiary hearing at its headquarters in Hartford. At that
    hearing, the defendants presented expert testimony
    from James J. Bajek, an expert in coastal structure
    permitting, and R. Scott Warren, an expert in coastal
    resources and tidal wetlands ecology. Both Bajek and
    Warren testified that the defendants’ application com-
    plied with the statutory and regulatory criteria and pol-
    icy relevant to the proposed regulated activities. The
    department also offered testimony from Susan Jacob-
    son, the department’s permit analyst, who testified that
    the proposed structure would comply with the tidal
    wetlands act.
    The plaintiff offered testimony in opposition to the
    proposed dock, in which she expressed concern over
    the potential visual impact that the dock would have on
    the surrounding area. In addition, the plaintiff presented
    expert testimony from Kenny, who stated that the pro-
    posed dock did not comply with portions of the tidal
    wetlands act due to the potential environmental impact
    stemming from pedestrian access to the proposed dock
    or motorboat activity in the vicinity of the proposed
    dock. Kenny also questioned whether the application
    complied with the coastal management act’s policy
    regarding impacts to vistas and viewpoints.
    On September 26, 2018, the hearing officer issued a
    posthearing directive, in which he ordered the parties
    to submit supplemental filings addressing ‘‘relevant
    statutory and regulatory policies and criteria, including
    the coastal management act, tidal wetlands act and
    statutes concerning structures, dredging and filling, and
    relevant implementing regulations’’ as well as ‘‘the sig-
    nificance of the [comment letter] filed by the [commis-
    sion], particularly in the context of . . . § 22a-113n.’’
    The parties each filed posthearing briefs and reply
    briefs.
    On February 22, 2019, the hearing officer issued a
    proposed final decision recommending that the defen-
    dants’ application be approved and that a permit for
    the proposed dock be issued. In his decision, the hearing
    officer first addressed the argument set forth in the
    commission’s public comment letter alleging that the
    commission’s recommendation regarding the defen-
    dant’s application was binding on the department. As
    an initial matter, the hearing officer clarified that the
    commission’s public comment letter was submitted as a
    public comment, intended to guide the hearing officer’s
    inquiry, and not as substantive evidence upon which
    the hearing officer could base his determination approv-
    ing or disapproving the defendants’ application. Specifi-
    cally, the hearing officer noted that, ‘‘[i]n order to place
    evidence into the record . . . status as an intervening
    party . . . is generally required.’’ Although the com-
    mission could have sought status as an intervening party
    in the proceeding as a matter of right, pursuant to § 22a-
    99, it did not do so in the proceedings before the hearing
    officer. Accordingly, the hearing officer concluded that,
    ‘‘while . . . [the commission’s] comment . . . [identi-
    fies] issues of local concern, and while the issues identi-
    fied in the comment that are relevant to this proceeding
    are addressed elsewhere in this decision, it is not at all
    clear that any type of ‘binding recommendation’ can be
    made by submitting a public comment.’’
    The hearing officer also determined that the commis-
    sion’s public comment letter never explicitly recom-
    mended that the department deny the defendants’ appli-
    cation. Rather, the hearing officer found that ‘‘the only
    ‘formal’ recommendation [made by the commission] is
    a request that the department provide a policy state-
    ment for consideration.’’ The hearing officer concluded
    that, because no statutory or regulatory criteria
    required that such a policy statement be issued before
    a permit for the proposed regulated activity is issued,
    the department was not bound by the recommendation
    set forth in the public comment letter.
    The hearing officer then determined that, even if the
    recommendation was properly submitted to the depart-
    ment, the statutory scheme regulating dock permitting
    would not prevent the department from approving the
    defendants’ application or issuing a permit. Specifically,
    the hearing officer concluded that the plain text of
    § 22a-361 (h), which mandates that the department
    ‘‘shall not issue a certificate or permit to authorize any
    dock or other structure in an area that was designated
    as inappropriate or unsuitable for such dock or other
    structure in a harbor management plan approved and
    adopted pursuant to section 22a-113m,’’ did not require
    that such a determination be made by the commission.
    Rather, the hearing officer concluded that the depart-
    ment, as opposed to the commission, is charged in the
    first instance with determining whether a dock is in an
    area designated as inappropriate or unsuitable in an
    approved harbor management plan.
    The hearing officer also interpreted the requirements
    of § 22a-113n (b), concluding that the plain language
    ‘‘does not discuss the recommendations of a [harbor
    management commission] regarding individual dock
    applications. The only ‘recommendations’ contem-
    plated by this section are those contained in the harbor
    management plan. It is entirely plausible that the recom-
    mendations that are binding, then, are those contained
    in an adopted harbor management plan, and that a rec-
    ommendation concerning an individual dock is simply
    advisory.’’
    Applying §§ 22a-361 and 22a-113n (b) to the defen-
    dants’ application, the hearing officer found that neither
    the plaintiff, nor the commission, had ‘‘identified any
    portion of [the plan] that indicate[d] that the location
    of the proposed dock is in an area identified as inappro-
    priate or unsuitable’’ and that his ‘‘own review of [the
    plan] . . . revealed no restriction.’’ Accordingly, the
    hearing officer concluded that nothing in the plan pre-
    vented the hearing officer from making a recommenda-
    tion to the department that the defendants’ application
    be approved.
    The hearing officer then assessed the plaintiff’s envi-
    ronmental claims, concluding that she had failed to
    satisfy her burden of proving that the proposed struc-
    ture was reasonably likely to cause an unreasonable
    environmental impact. Specifically, the hearing officer
    determined that the plaintiff had failed to produce suffi-
    cient evidence demonstrating that the proposed struc-
    ture would have an unreasonable impact on nearby
    viewpoints and vistas, that pedestrian access to and
    from the proposed structure would result in the damage
    or destruction of the surrounding low marsh area, and
    that motorboat access to and from the proposed struc-
    ture would damage local tidal wetlands.
    Finally, the hearing officer, relying on expert testi-
    mony produced by both the defendants and the depart-
    ment, determined that the defendants had met their
    burden of demonstrating that their proposed dock com-
    plied with the statutory and regulatory criteria set forth
    in the coastal management act; the structures, dredging
    and fill act; and the tidal wetlands act and associated
    regulations, § 22a-30-1 et seq. of the Regulations of Con-
    necticut State Agencies. Specifically, the hearing officer
    concluded: ‘‘[T]he construction of the proposed struc-
    ture will provide the [defendants] with reasonable
    access to the water while balancing intrusions into the
    public trust and limiting environmental impacts. The
    application and evidence presented during the hearing
    support the assertion that the [defendants’] exercise of
    their littoral right to wharf out can be achieved while
    minimizing impacts to coastal resources, wildlife, navi-
    gation, and costal sedimentation and erosion patterns.
    . . . The application and evidence placed in the eviden-
    tiary record indicate that the proposed structure will
    have no impact on the health or welfare of the public
    or to any fisheries, wildlife or sediments. The record
    supports the factual findings and conclusions based
    on those findings that potential environmental impacts
    from the proposed project have been sufficiently mini-
    mized and that the project is consistent with applicable
    policies regarding coastal resources management, satis-
    fying the [defendants’] burden in this matter.’’ (Citation
    omitted.)
    Following the hearing officer’s issuance of the pro-
    posed final decision, the plaintiff filed exceptions,
    arguing, inter alia, that the hearing officer improperly
    had declined to grant her intervening party status under
    § 22a-3a-6 (k) of the regulations and that the proposed
    final decision violated § 22a-113n (b) by disregarding
    the commission’s recommendation set forth in the pub-
    lic comment letter that the application not be approved.
    The department heard oral argument on the exceptions
    on July 24, 2019.
    On October 31, 2019, the deputy commissioner issued
    a final decision, which adopted the findings of fact
    and conclusions of law set forth in the proposed final
    decision. The deputy commissioner also addressed the
    issues raised in the plaintiff’s exceptions concerning
    the plaintiff’s intervenor status and the commission’s
    authority to issue recommendations that are binding
    on the department pursuant to § 22a-113n. Regarding
    the former, the deputy commissioner found that the
    plaintiff had declined the hearing officer’s invitation to
    allege additional, specific facts concerning the plain-
    tiff’s ‘‘legal rights, duties or privileges’’ sufficient to con-
    fer upon her intervenor party status under § 22a-3a-6
    (k) of the regulations. The deputy commissioner noted
    that the plaintiff’s ‘‘lack of action [stood] in sharp con-
    trast to the action taken’’ regarding her environmental
    claims, wherein she submitted a motion for reconsider-
    ation asserting new facts supported by an affidavit from
    an expert witness. The deputy commissioner concluded
    that, ‘‘[h]aving chosen to take no action, the [plaintiff]
    cannot now’’ complain that she was denied intervening
    party status under § 22a-3a-6 (k) of the regulations.
    With regard to the plaintiff’s exception concerning
    the commission’s authority to make binding recommen-
    dations pursuant to § 22a-13n, the deputy commissioner
    concluded: ‘‘A harbor management plan approved by
    the [department] pursuant to [General Statutes] § 22a-
    113m may contain recommendations that, unless cause
    is shown, are binding [on the department], but it is
    the approved management plan that must contain or
    provide such recommendations. In this case, the rec-
    ommendations made in the [comment letter]—that the
    department provide a certain policy statement and that
    the department consider the policies in the [commis-
    sion’s] management plan—were not required by, and
    it is not clear even originated in, the [commission’s]
    approved management plan. Moreover, the [commis-
    sion’s] statement that it was unable to ‘make a favorable
    recommendation’ on the [defendants’] application not
    only fails to qualify as a recommendation but, more
    significantly, suffers from the same problem previously
    noted; the recommendation is simply not contained
    in the [commission’s] approved management plan.’’
    (Emphasis added; footnote omitted.) Accordingly, the
    deputy commissioner affirmed the decision of the hear-
    ing officer set forth in the proposed final decision.
    On November 27, 2019, the plaintiff appealed from
    the department’s final decision to the Superior Court,
    pursuant to § 4-183 of the Uniform Administrative Pro-
    cedure Act (UAPA), General Statutes § 4-166 et seq. In
    her complaint, the plaintiff alleged that (1) she was
    classically and statutorily aggrieved by the department’s
    decision, (2) the department’s final decision enabled
    the defendants to evade municipal zoning regulations,
    (3) the department improperly interpreted § 22a-113n
    in concluding that the commission’s recommendation
    that the application not be granted was not binding
    on the department, (4) the final decision violated the
    structures, dredging and fill act; the tidal wetlands act;
    and the coastal management act, and (5) the decision
    was contrary to the department’s publicly stated goals.13
    On February 3, 2020, the intervening plaintiffs filed
    a motion to intervene in the plaintiff’s administrative
    appeal as parties plaintiff, pursuant to Practice Book
    § 9-1814 and General Statutes § 52-107,15 which the court,
    Moukawsher, J., granted on October 10, 2020.
    On March 6, 2020, the department filed a motion to
    dismiss two of the plaintiff’s claims on administrative
    appeal, specifically, (1) that the department’s final deci-
    sion violated local zoning ordinances, and (2) that the
    department improperly concluded that § 22a-113n did
    not grant the commission the authority to make a rec-
    ommendation that was binding on the department con-
    cerning the defendants’ application. In its accompa-
    nying memorandum of law, the department argued that
    the plaintiff did not have standing to pursue those
    claims because she had been permitted to participate
    in the defendants’ application proceedings only as a
    statutory intervenor, pursuant to § 22a-19, for the nar-
    row purpose of pursuing environmental claims.16 In
    addition, the department argued that, even if the plain-
    tiff was permitted to pursue those claims, she had not
    demonstrated classical aggrievement because her
    claimed interests were no different from those of any
    other member of the public. On March 19, 2020, the
    defendants also filed a motion to dismiss the plaintiff’s
    nonenvironmental claims, alleging that the plaintiff had
    failed to demonstrate that she was either classically or
    statutorily aggrieved by the department’s final decision
    and therefore lacked standing to pursue those claims.
    On September 22, 2020, the court issued a memoran-
    dum of decision denying both the department’s and the
    defendants’ motions to dismiss. In its memorandum of
    decision, the court determined that the plaintiff had
    successfully alleged statutory standing pursuant to
    § 22a-19 because ‘‘[h]er complaint is partly premised
    on claims of environmental harm, including ‘noise and
    air pollution,’ ‘degrading visual quality’ and violation of
    three environmental statutes . . . .’’ In addition, the
    court concluded that the plaintiff had adequately dem-
    onstrated classical aggrievement by showing ‘‘a specific
    personal and arguably legal interest at least plausibly
    injured by [the final decision].’’ Specifically, the court
    pointed to the plaintiff’s allegations that she (1) ‘‘is an
    award-winning landscaper whose specially maintained
    garden views would be damaged by the [dock] struc-
    ture, the noise and the air pollution . . . [and that the
    proposed dock] will diminish the value of her property
    as a place of enjoyment and a showplace for her work,
    and (2) ‘‘that boat exhaust will potentially make her
    asthma worse.’’ The court concluded, accordingly, that
    the plaintiff adequately had demonstrated ‘‘some kind
    of standing’’ for each claim alleged in her appeal.
    Each party submitted trial briefs to the court, and,
    on January 25, 2021, the court heard argument on those
    briefs. At argument, the plaintiff asserted three claims
    in support of her position that the final decision of the
    department granting the defendants’ application should
    be overturned. First, the plaintiff claimed that the
    department, in the final decision, improperly placed
    the burden of proof on her to demonstrate ‘‘feasible
    alternatives’’ to the defendants’ proposed dock. Second,
    the correct burden of proof notwithstanding, the plain-
    tiff argued that the department erred in declining to
    determine whether feasible alternatives existed to the
    proposed dock, including a community dock located
    near the subject property. Third, the plaintiff claimed
    that the department misinterpreted and, therefore, vio-
    lated § 22a-113n by failing to regard the commission’s
    recommendation in the public comment letter concern-
    ing the defendants’ proposed dock ‘‘as binding.’’ The
    intervening plaintiffs also argued that the department
    misconstrued § 22a-113n in determining that the com-
    mission’s recommendation that the defendants’ applica-
    tion not be approved was not binding on the depart-
    ment.
    In response, the defendants renewed their claim that
    neither the plaintiff nor the intervening plaintiffs had
    standing to assert the claim concerning the proper inter-
    pretation of § 22a-113n. Specifically, the defendants
    contended that the plaintiff, as a member of the general
    public, had no personal or legal interest in the commis-
    sion’s authority to make recommendations that are
    binding on the department under § 22a-113n. With
    regard to the intervening plaintiffs, the defendants
    argued that, because the commission never sought to
    intervene as a party in the administrative proceedings
    below, the public comment letter was not ‘‘evidence in
    the record’’ upon which the department could decide
    the defendants’ permit application. Accordingly, the
    defendants argued that the intervening plaintiffs did not
    have a basis upon which to overturn the department’s
    decision.
    In addition, both the department and the defendants
    argued that the Harbor Management Plan did not con-
    tain a provision regarding individual dock placements
    and, therefore, that the commission’s recommendation
    on the defendants’ application could not be binding on
    the department for purposes of § 22a-113n. Moreover,
    both the defendants and the department contended that
    the defendants had adequately satisfied their burden of
    proof in demonstrating that their application complied
    with the structures, dredging and fill act; the tidal wet-
    lands act; and the coastal management act; and, there-
    fore, were not required to produce additional evidence
    concerning prudent and feasible alternatives.
    On January 27, 2021, the court issued a memorandum
    of decision rendering judgment in favor of the defen-
    dants and the department. The court first determined
    that both the hearing officer, in the proposed final deci-
    sion, and the deputy commissioner, in the final decision,
    applied the correct burdens of proof to both the plaintiff
    and the defendants. The court then concluded that
    § 22a-113n did not confer on the commission a broad
    veto power to make recommendations that are binding
    on the department concerning permits that affect har-
    bors. Rather, the court concluded that § 22a-113n
    empowers harbor management commissions to make
    binding recommendations on issues already included
    within an approved harbor management plan. Stated
    otherwise, § 22a-113n ‘‘says nothing about recommend-
    ing anything about individual permit applications.
    Instead, it is exclusively about recommending for
    approval the content of a harbor management plan. It
    certainly makes sense to make plan recommendations
    approved by the state binding on the state, but that’s
    as far as it goes.’’ (Emphasis added.) Finally, the court
    concluded that the department’s decision to approve
    the defendants’ application was ‘‘supported by substan-
    tial evidence in the record, showing appropriate con-
    cern for [the plaintiff’s] claims and for minimizing envi-
    ronmental impact.’’17 Accordingly, the court affirmed
    the department’s final decision and dismissed the plain-
    tiff’s administrative appeal. These appeals followed.
    I
    AC 44551
    We begin by addressing the intervening plaintiffs’
    appeal from the judgment of the Superior Court. On
    appeal, the intervening plaintiffs claim that the court
    improperly concluded that § 22a-113n did not grant the
    commission the statutory authority to make recommen-
    dations that are binding on the department concerning
    individual dock permit applications within its jurisdic-
    tion. We disagree.
    The following relevant standard of review and legal
    principles govern our resolution of the intervening
    plaintiffs’ claim. ‘‘Judicial review of [an administrative
    agency’s] action is governed by the . . . UAPA . . .
    and the scope of that review is very restricted. . . .
    With regard to questions of fact, it is neither the function
    of the trial court nor of this court to retry the case or
    to substitute its judgment for that of the administrative
    agency. . . .
    ‘‘The substantial evidence rule governs judicial
    review of administrative fact-finding under [the] UAPA.
    General Statutes § 4-183 (j) (5) and (6). Substantial evi-
    dence exists if the administrative record affords a sub-
    stantial basis of fact from which the fact in issue can
    be reasonably inferred. . . . This substantial evidence
    standard is highly deferential and permits less judicial
    scrutiny than a clearly erroneous or weight of the evi-
    dence standard of review. . . . The burden is on the
    [plaintiff] to demonstrate that the [agency’s] factual
    conclusions were not supported by the weight of sub-
    stantial evidence on the whole record. . . .
    ‘‘Even as to questions of law, [t]he court’s ultimate
    duty is only to decide whether, in light of the evidence,
    the [agency] has acted unreasonably, arbitrarily, ille-
    gally, or in abuse of its discretion. . . . Conclusions of
    law reached by the administrative agency must stand
    if the court determines that they resulted from a correct
    application of the law to the facts found and could
    reasonably and logically follow from such facts. . . .
    ‘‘Ordinarily, this court affords deference to the con-
    struction of a statute applied by the administrative
    agency empowered by law to carry out the statute’s
    purposes. . . . Cases that present pure questions of
    law, however, invoke a broader standard of review than
    is ordinarily involved in deciding whether, in light of
    the evidence, the agency has acted unreasonably, arbi-
    trarily, illegally or in abuse of its discretion. . . . Fur-
    thermore, when a state agency’s determination of a
    question of law has not previously been subject to judi-
    cial scrutiny . . . the agency is not entitled to special
    deference.’’ (Citations omitted; internal quotation

    mental Protection,

    , 136–37, 
    778 A.2d 7
     (2001). To the extent that the claim raised by the
    intervening plaintiffs requires us to review the depart-
    ment’s construction of § 22a-113n, we are not persuaded
    that its construction should be afforded deference
    because it was the product of a ‘‘technical case-by-case
    review . . . that . . . calls for agency expertise.’’

    A
    As a threshold matter, the defendants claim that the
    intervening plaintiffs’ claim is not properly before this
    court. Specifically, the defendants argue that (1) the
    commission had no grounds to intervene below because
    the plaintiff lacked standing to raise the issue concern-
    ing the proper interpretation of § 22a-113n on adminis-
    trative appeal to the Superior Court, and (2) the issue
    of whether a harbor management commission’s recom-
    mendation is binding on the department was never
    raised because the commission never actually made a
    recommendation concerning the defendants’ dock
    application. We are not persuaded.
    The following additional facts and procedural history
    are relevant to our disposition of the defendants’ claim.
    On November 27, 2019, the plaintiff appealed from the
    department’s final decision to the Superior Court, alleg-
    ing, inter alia, that the department improperly interpre-
    ted § 22a-113n in concluding that the commission’s rec-
    ommendation that the application not be granted was
    not binding on the department. On February 3, 2020,
    the intervening plaintiffs filed a motion to intervene in
    the plaintiff’s administrative appeal as parties plaintiff,
    pursuant to § 52-107 and Practice Book § 9-18. The
    intervening plaintiffs filed a memorandum of law in
    support of their motion, in which they argued, inter
    alia, that they were entitled to intervene as of right
    due to their substantial interest in the plaintiff’s claim
    concerning the proper interpretation of § 22a-113n.18
    Specifically, the intervening plaintiffs asserted that the
    court’s ruling on the § 22a-113n claim would have a
    direct and significant impact on their ability to regulate
    activities concerning harbors and waterways within
    their jurisdiction, and that the plaintiff did not ade-
    quately represent their interest because it was possible
    for her to prevail on one of her other claims, despite
    an adverse ruling on the § 22a-113n issue.
    On February 11, 2020, the department filed an opposi-
    tion to the intervening plaintiffs’ motion to intervene,
    arguing that it was procedurally improper. The depart-
    ment contended that, because the intervening plaintiffs
    were effectively raising issues of error in the depart-
    ment’s final decision, and because the intervening plain-
    tiffs could have, but chose not to, participate in the
    administrative proceeding below as a matter of right,
    the proper procedural vehicle was to appeal from the
    department’s final decision, rather than attempting to
    intervene in the plaintiff’s administrative appeal.
    On October 10, 2020, the court, Moukawsher, J.,
    issued an order granting the intervening plaintiffs’
    motion to intervene as of right. In its order, the court
    determined that ‘‘[t]his motion is not an attempted
    appeal of an administrative decision. . . . Instead, it
    is a town and its harbor management commission’s
    request to intervene to protect rights they say would
    be affected by this action. The court doesn’t have to
    decide those rights to let them intervene. It need only
    observe that the proposed intervenors have colorable
    claims that a legal ruling in this case might affect their
    rights in matters related to the town and its harbor.
    Since this is not a question of an appeal but an interven-
    tion, Practice Book [§] 14-6 specifically makes this
    motion subject to the ordinary rules of civil action inter-
    vention. Practice Book [§] 9-18 provides that the court
    should join parties with ‘an interest . . . the judgment
    will affect . . . .’ The parties here have plausibly stated
    such an interest, and that is good grounds to allow them
    to intervene.’’19
    1
    On appeal, the defendants argue that the court
    improperly granted the intervening plaintiffs’ motion to
    intervene because the plaintiff had no standing to bring
    the § 22a-113n issue in her administrative appeal in the
    first instance. As such, the defendants contend that,
    because the intervening plaintiffs’ claim was ‘‘deriva-
    tive’’ of the plaintiff’s claim, and because the plaintiff
    improperly brought that claim before the Superior
    Court, the intervening plaintiffs could no longer be con-
    sidered necessary parties to the plaintiff’s administra-
    tive appeal sufficient to grant them intervenor status.
    Stated otherwise, the defendants contend that, because
    the plaintiff had standing to pursue only her environ-
    mental claims pursuant to § 22a-19,20 the intervening
    plaintiffs lacked a direct and substantial interest in the
    outcome of the matter such that their interests could
    be impaired by the court’s decision. We conclude that
    the intervening plaintiffs’ standing to pursue their § 22a-
    113n claim was not dependent on the plaintiff’s standing
    to bring the same claim.
    Our Supreme Court has never considered the issue
    of whether an intervening party may continue to litigate
    an action after the claims brought by the original party
    have been dismissed or the original party has been
    found to lack standing to pursue the particular claim
    that affects the interests of the intervening party in the
    first instance. ‘‘In the absence of controlling or persua-
    sive Connecticut authority, we look to the law of other
    jurisdictions.’’ Pease v. Charlotte Hungerford Hospital,
    
    325 Conn. 363
    , 375, 
    157 A.3d 1125
     (2017). Our review
    of several decisions from other jurisdictions reveals
    that both federal courts and the courts of other states
    permit intervening parties to proceed, even when the
    claims brought by the original party have been dis-
    missed due to lack of subject matter jurisdiction, when
    (1) there is an independent jurisdictional basis for the

    claim would result in unnecessary delay. See, e.g., Goto

    Stated otherwise, when an intervening party meets
    those two requirements, a court may treat an interve-
    nor’s claim as a separate action and decide the matter
    while dismissing the original action for lack of subject
    matter jurisdiction. See Goto v. District of Columbia
    Board of Zoning Adjustment, supra, 922.
    Even if we assume, without deciding, that the plaintiff
    lacked standing to bring the § 22a-113n claim, it is clear
    that the intervening plaintiffs had an independent juris-
    dictional basis to bring the § 22a-113n claim and that
    refusing to adjudicate the claim would result in unnec-
    essary delay and a waste of judicial resources.
    ‘‘Subject matter jurisdiction involves the authority of
    the court to adjudicate the type of controversy pre-
    sented by the action before it. . . . [A] court lacks dis-
    cretion to consider the merits of a case over which it
    is without jurisdiction . . . . [T]his court has often
    stated that the question of subject matter jurisdiction,
    because it addresses the basic competency of the court,
    can be raised by any of the parties, or by the court sua
    sponte, at any time. . . . A court does not have subject
    matter jurisdiction to hear a matter unless the plaintiff
    has standing to bring the action.’’ (Citation omitted;

     (2016).
    ‘‘Standing is the legal right to set judicial machinery
    in motion. One cannot rightfully invoke the jurisdiction
    of the court unless he [or she] has, in an individual or
    representative capacity, some real interest in the cause
    of action, or a legal or equitable right, title or interest
    in the subject matter of the controversy. . . . When
    standing is put in issue, the question is whether the
    person whose standing is challenged is a proper party
    to request an adjudication of the issue . . . . Standing
    requires no more than a colorable claim of injury; a
    [party] ordinarily establishes . . . standing by allega-
    tions of injury. Similarly, standing exists to attempt to
    vindicate arguably protected interests. . . . Standing
    is established by showing that the party claiming it is
    authorized by statute to bring an action, in other words,
    statutorily aggrieved, or is classically aggrieved. . . .
    [Statutory] [s]tanding concerns the question [of]
    whether the interest sought to be protected by the com-
    plainant is arguably within the zone of interests to be
    protected or regulated by the statute or constitutional
    guarantee in question. . . .
    ‘‘The fundamental test for determining [classical]
    aggrievement encompasses a [well settled] twofold
    determination: [F]irst, the party claiming aggrievement
    must successfully demonstrate a specific, personal and
    legal interest in [the challenged action], as distinguished
    from a general interest, such as is the concern of all
    members of the community as a whole. Second, the
    party claiming aggrievement must successfully estab-
    lish that this specific personal and legal interest has
    been specially and injuriously affected by the [chal-
    lenged action]. . . . Aggrievement is established if
    there is a possibility, as distinguished from a certainty,
    that some legally protected interest . . . has been
    adversely affected.’’ (Footnote omitted; internal quota-

     (2015).
    In the present case, it is clear that the intervening
    plaintiffs have standing to bring a claim concerning the
    proper interpretation and scope of § 22a-113n. Section
    22a-113n (b) provides in relevant part that, ‘‘[u]pon
    adoption of the [harbor management] plan, any recom-
    mendation made [by a harbor management commis-
    sion] pursuant to this section shall be binding on any
    official of the state, municipality or any other political
    subdivision when making regulatory decisions or under-
    taking or sponsoring development affecting the area
    within the commission’s jurisdiction, unless such offi-
    cial shows cause why a different action should be
    taken.’’ Accordingly, the plain text of § 22a-113n (b)
    directly implicates the intervening plaintiffs’ authority
    to make recommendations to state and local officials
    concerning activities affecting harbor areas within its
    jurisdiction. As the intervening plaintiffs alleged in their
    motion to intervene, the ‘‘decision in this case will have
    far-reaching consequences for the [intervening plain-
    tiffs], not only with regard to future dock applications
    but with regard to any other type of application that is
    reviewed by the commission, which, ultimately needs
    a permit from [the department].’’ This is precisely the
    sort of concrete and particularized allegation sufficient
    to raise a ‘‘ ‘colorable claim of injury . . . .’ ’’ Hand-
    some, Inc. v. Planning & Zoning Commission, supra,
    
    317 Conn. 525
    ; see also Conservation Commission v.
    Red 11, LLC, 
    135 Conn. App. 765
    , 774, 
    43 A.3d 244
    (2012) (‘‘Two of the four criteria for intervention as of
    right, namely the direct and substantial interest in the
    subject matter, and the impairment to the movant’s
    interest if he or she is not involved in the case are, in
    essence, equivalent to the test for aggrievement. . . .
    Thus, [i]mplicit in the granting of a motion to intervene
    is the determination that the party has a right which
    could be adversely affected and that his interest is pres-
    ently not adequately protected.’’ (Citations omitted;
    internal quotation marks omitted.)). We conclude,
    accordingly, that the intervening plaintiffs had an inde-
    pendent jurisdictional basis to bring the § 22a-113n
    claim.
    Second, it is clear that failure to adjudicate the
    intervening plaintiffs’ claim would result in unnecessary
    delay. Were we to dismiss the intervening plaintiffs’
    claim on the ground that the original plaintiff lacked
    standing to bring the § 22a-113n claim, the intervening
    plaintiffs would then be required to file a petition for
    a declaratory ruling pursuant to the UAPA. See General
    Statutes §§ 4-17522 and 4-176.23 The intervening plaintiffs
    would then be left with two options. They could wait
    for the department to issue a ruling concerning the
    proper construction of § 22a-113n. Conversely, if the
    department failed to issue a ruling within sixty days of
    the filing of the petition, decided not to issue a declara-
    tory ruling, or was deemed as having not decided to
    issue a declaratory ruling, the intervening plaintiffs
    could file a declaratory judgment action in the trial
    court. See General Statutes §§ 4-175 and 4-176. In the
    present case, both the department and the court already
    have issued rulings concerning the proper construction
    of § 22a-113n. To require the intervening plaintiffs to
    again seek rulings concerning the same issue would be
    redundant. We conclude, accordingly, that dismissing
    the intervening plaintiffs’ claim would lead to unneces-
    sary delay and be a waste of judicial resources.
    2
    Having determined in part I A 1 of this opinion that
    the intervening plaintiffs had standing to raise the § 22a-
    113n issue in the administrative appeal in the first
    instance, we briefly address a related reviewability con-
    cern raised by the defendants, specifically, whether this
    court should refuse to consider the proper construction
    of § 22a-113n because the issue of whether a harbor
    management commission’s recommendation is binding
    on the department was never properly raised during
    the administrative proceedings below. Specifically, the
    defendants contend that (1) the comment letter that the
    commission submitted to the department never actually
    made a recommendation concerning the defendants’
    application24 and (2) the comment letter was only a
    public comment and, therefore, not evidence in the
    administrative record to be considered when making a
    determination concerning a proposed dock application.
    We conclude that the issue concerning the proper con-
    struction of § 22a-113n is properly before this court.
    The defendants’ argument focuses on the commis-
    sion’s role during the administrative proceedings below.
    In particular, the defendants point to the fact that § 22a-
    99 entitled the commission to submit written testimony
    and ‘‘appear by right as a party’’ in the administrative
    hearings concerning the defendants’ application but
    that the commission elected not to. Accordingly, the
    defendants contend that the comment letter submitted
    by the commission to the department was merely a
    public comment and not evidence in the record that
    could affect the decision concerning the department’s
    decision regarding the defendants’ application.
    We agree with the defendants with respect to the
    nature of the commission’s involvement in the underling
    administrative proceedings. Specifically, the letter sent
    to the department was only a public comment and not
    evidence to be considered in determining whether to
    grant the defendants’ application. See Regs., Conn. State
    Agencies § 22a-3a-6 (t).25 We conclude, however, that
    the nature of the intervening plaintiffs’ participation in
    the administrative appeal before the Superior Court
    substantially differed from their involvement before the
    department, such that the issue concerning the proper
    interpretation of § 22a-113n is properly before this
    court.
    As an initial matter, although both the hearing officer
    and deputy commissioner questioned whether the com-
    mission had made a valid recommendation via the com-
    ment letter, each assessed the recommendation within
    the context of § 22a-113n and issued an interpretation
    concerning the correct construction of § 22a-113n.26
    Specifically, both the hearing officer and the deputy
    commissioner concluded that a recommendation made
    by a harbor management commission only has binding
    effect on the department when the recommendation
    stems from content or language included within an
    approved harbor management plan.
    The plaintiff challenged the department’s ruling con-
    cerning the proper scope and interpretation of § 22a-
    113n in her complaint to the Superior Court. Upon
    receiving notice that the § 22a-113n issue was to be
    adjudicated before the Superior Court, the intervening
    plaintiffs filed a motion to intervene, alleging, inter alia,
    that the court’s decision regarding the proper interpre-
    tation of § 22a-113n would have a ‘‘direct and significant
    impact on their authority and jurisdiction under the
    [Harbor Management Act, General Statutes § 22a-113k
    et seq.] and on their future ability to implement the
    goals and policies of the [p]lan.’’ Stated otherwise, the
    intervening plaintiffs recognized that the court’s con-
    struction of § 22a-113n during the administrative appeal
    could implicate their authority to make binding recom-
    mendations as to future permit applications or other
    matters affecting the harbors within the intervening
    plaintiffs’ jurisdiction.
    Finally, as we have explained previously in this opin-
    ion, the court considered the issue regarding the proper
    interpretation of § 22a-113n and issued a decision on
    the merits, concluding, in its memorandum of decision,
    that the commission had no authority to make a binding
    recommendation concerning the defendants’ applica-
    tion. In light of the foregoing, we are not persuaded
    that the issue of whether a harbor management commis-
    sion’s recommendation is binding on the department
    was not properly raised during the administrative pro-
    ceedings below.
    B
    We now turn to the merits of the intervening plaintiffs’
    claim, which concerns the proper interpretation of
    § 22a-113n. Specifically, the parties dispute whether
    § 22a-113n grants to the commission the authority to
    make recommendations that are binding on the depart-
    ment concerning individual dock placements within the
    commission’s jurisdiction. We conclude that § 22a-113n
    allows harbor management commissions to make rec-
    ommendations that are binding on the department only
    when such recommendations arise from content
    already included within an approved harbor manage-
    ment plan.
    Before turning to the statutory provision at issue in
    the present appeal, we find it necessary to first review
    the statutory framework that governs the permitting of
    individual dock placements, as well as the legislative
    scheme that regulates the establishment of harbor man-
    agement commissions and harbor management plans.
    In enacting § 22a-361 (d) (1), our legislature delegated
    to the department the power to ‘‘issue a general permit
    for any minor activity . . . if the commissioner deter-
    mines that such activity would (A) cause minimal envi-
    ronmental effects when conducted separately, (B)
    cause only minimal cumulative environmental effects,
    (C) not be inconsistent with the considerations and
    the public policy set forth in sections 22a-28 to 22a-35,
    inclusive, and section 22a-359, as applicable, (D) be
    consistent with the policies of the Coastal Management
    Act, and (E) constitute an acceptable encroachment
    into public lands and waters. Such activities may
    include . . . construction of individual residential
    docks which do not create littoral or riparian conflicts,
    navigational interference, or adverse impacts to coastal
    resources, as defined in section 22a-93, which are not
    located in tidal wetlands, as defined in section 22a-29,
    and which extend no further than forty feet waterward
    of mean high water or to a depth of minus four feet
    mean low water, whichever point is more landward.’’
    The department’s ability to administer individual
    dock permits is limited by § 22a-361 (h), which provides
    that, ‘‘[n]otwithstanding any other provision of this sec-
    tion, the [department] shall not issue a certificate or
    permit to authorize any dock or other structure in an
    area that was designated as inappropriate or unsuitable
    for such dock or other structure in a harbor manage-
    ment plan approved and adopted pursuant to section
    22a-113m.’’
    Section 22a-113k et seq. governs the creation of har-
    bor management commissions and the promulgation of
    harbor management plans. Section 22a-113k (a) pro-
    vides that ‘‘[a]ny municipality having within its limits
    navigable waters as defined in subsection (b) of section
    15-3a may establish by ordinance one or more harbor
    management commissions or may designate any
    existing board, commission, council, committee or
    other agency as a harbor management commission.
    . . . The ordinance shall designate the area within the
    territorial limits of the municipality and below the mean
    high water that shall be within the jurisdiction of a
    commission and shall set forth the number of members
    of a commission, their method of selection, terms of
    office and procedure for filling any vacancy.’’
    Section 22a-113m empowers harbor management
    commissions to promulgate harbor management plans
    ‘‘for the most desirable use of the harbor for recre-
    ational, commercial, industrial and other purposes.’’
    Importantly, harbor management plans must be submit-
    ted for approval by the department and only after
    department approval may the plan be adopted by ordi-
    nance ‘‘by the legislative body of each municipality
    establishing the [harbor management] commission.’’
    General Statutes § 22a-113m.
    Section 22a-113n, the provision at issue in the present
    appeal, is titled ‘‘[c]ontent of plan’’ and delineates cer-
    tain subject matter that either must be included in a
    harbor management plan, or subject matter that a har-
    bor management plan may include, pursuant to which
    harbor management commissions may make binding
    recommendations to the department. Specifically,
    § 22a-113n provides: ‘‘(a) The plan shall identify existing
    and potential harbor problems, establish goals and
    make recommendations for the use, development and
    preservation of the harbor. Such recommendations
    shall identify officials responsible for enforcement of
    the plan and propose ordinances to implement the plan.
    The plan shall include, but not be limited to, provisions
    for the orderly, safe and efficient allocation of the har-
    bor for boating by establishing (1) the location and
    distribution of seasonal moorings and anchorages, (2)
    unobstructed access to and around federal navigation
    channels, anchorage areas and harbor facilities, and
    (3) space for moorings and anchorages for transient
    vessels.
    ‘‘(b) The plan may recommend: (1) Boundaries for
    development areas to be approved and established by
    the Commissioner of Energy and Environmental Protec-
    tion in accordance with the provisions of section 22a-
    360; (2) designations for channels and boat basins for
    approval and adoption by the Commissioner of Energy
    and Environmental Protection in accordance with the
    provisions of section 22a-340; (3) lines designating the
    limits of areas for the location of vessels with persons
    living aboard to be approved and adopted by the direc-
    tor of health in accordance with section 19a-227; (4)
    pump-out facilities, including the designation of no dis-
    charge zones in accordance with Section 312 of the
    federal Clean Water Act; and (5) regulations for the
    operation of vessels on the harbor pursuant to the provi-
    sions of section 15-136. Upon adoption of the plan, any
    recommendation made pursuant to this section shall
    be binding on any official of the state, municipality
    or any other political subdivision when making regu-
    latory decisions or undertaking or sponsoring develop-
    ment affecting the area within the commission’s juris-
    diction, unless such official shows cause why a
    different action should be taken.’’ (Emphasis added.)
    It is well established that ‘‘[t]he process of statutory
    interpretation involves the determination of the mean-
    ing of the statutory language as applied to the facts of
    the case, including the question of whether the language
    does so apply. . . . When construing a statute, [o]ur
    fundamental objective is to ascertain and give effect to
    the apparent intent of the legislature. . . . In seeking
    to determine that meaning, General Statutes § 1-2z
    directs us first to consider the text of the statute itself
    and its relationship to other statutes. If, after examining
    such text and considering such relationship, the mean-
    ing of such text is plain and unambiguous and does
    not yield absurd or unworkable results, extratextual
    evidence of the meaning of the statute shall not be
    considered. . . . Furthermore, [t]he legislature is
    always presumed to have created a harmonious and
    consistent body of law . . . [so that] [i]n determining
    the meaning of a statute . . . we look not only at the
    provision at issue, but also to the broader statutory
    scheme to ensure the coherency of our construction.’’

    On appeal, the intervening plaintiffs focus on the final
    sentence of § 22a-113n (b), which provides, ‘‘[u]pon
    adoption of the plan, any recommendation made pursu-
    ant to this section shall be binding on any official of
    the state, municipality or any other political subdivision
    when making regulatory decisions or undertaking or
    sponsoring development affecting the area within the
    commission’s jurisdiction, unless such official shows
    cause why a different action should be taken.’’ The
    intervening plaintiffs contend that this clause delegates
    to the commission the power to make recommenda-
    tions that are binding on the department regarding indi-
    vidual dock permits. Specifically, the intervening plain-
    tiffs point to the phrase ‘‘regulatory decisions,’’ arguing
    that, because the department’s review and permitting
    of individual dock applications is a regulatory decision
    made by a state official that affects harbors and water-
    ways within the commission’s jurisdiction, ‘‘any recom-
    mendation [made by the commission] concerning regu-
    latory decisions by a state official . . . are binding on
    that official, unless the official can show cause why a
    different action should be taken.’’
    By contrast, the department and the defendants argue
    that the plain language of § 22a-113n (b) only permits
    harbor management commissions to make binding rec-
    ommendations concerning content specifically found
    within a preapproved harbor management plan.
    Because the town’s harbor management plan does not
    contain any provisions concerning individual dock
    placements, the department and the defendants con-
    tend, § 22a-113n does not provide the commission with
    the authority to make a binding recommendation con-
    cerning the defendants’ application. We agree with the
    department and the defendants.
    As an initial matter, § 22a-113n is titled ‘‘[c]ontent of
    plan’’ and makes continued reference to ‘‘the plan’’
    throughout the statutory text. (Emphasis added.)
    Indeed, subsection (a) begins, ‘‘[t]he plan shall iden-
    tify,’’ and subsection (b) states, ‘‘[t]he plan may recom-
    mend.’’ (Emphasis added.) General Statutes § 22a-113n.
    In addition, the final sentence of § 22a-113n (b), on
    which the intervening plaintiffs rely, begins ‘‘[u]pon
    adoption of the plan, any recommendation made pur-
    suant to this section shall be binding on any official of
    the state . . . .’’ (Emphasis added.) General Statutes
    § 22a-113n (b). Accordingly, we construe the repeated
    reference in § 22a-113n to an approved harbor manage-
    ment plan to mean that any binding recommendation
    promulgated by a harbor management commission,
    including recommendations concerning regulatory
    decisions, must refer to content already contained
    within an approved harbor management plan. Indeed,
    the plain text of § 22a-113n (b) limits binding recom-
    mendations to recommendations ‘‘made pursuant to
    this section.’’ Stated otherwise, binding recommenda-
    tions must be made pursuant to the content of the
    approved harbor management plan.
    Had the legislature intended to empower harbor man-
    agement commissions with the authority to make rec-
    ommendations that are binding on the department
    regarding subject matter not contained within an
    approved harbor management plan, as the intervening
    plaintiffs suggest, it would have done so explicitly. Spe-
    cifically, the legislature would have stated that the har-
    bor management commission, irrespective of any plan,
    is charged with identifying existing and potential harbor
    problems, as well as making recommendations pursu-
    ant to the five enumerated criteria in § 22a-113n (b).
    Indeed, that is precisely what the legislature provided
    for in General Statutes § 22a-113p, which provides in
    relevant part that ’’[t]he commission may review and
    make recommendations, consistent with the plan, on
    any proposal affecting the real property on, in or contig-
    uous to the harbor that is received by any zoning com-
    mission, planning commission or combined planning
    and zoning commission, zoning board of appeals, his-
    toric district commissions, flood and erosion control
    board, harbor improvement agency, port authority,
    redevelopment agency, shellfish commission, sewer
    commission, water pollution control authority or spe-
    cial district with zoning or other land use authority.’’
    (Emphasis added.) The legislature, therefore, intended
    to empower harbor management commissions to make
    recommendations to local agencies concerning propos-
    als ‘‘affecting the real property on, in or contiguous
    to the harbor,’’ so long as such recommendations are
    consistent with the harbor management plan. By con-
    trast, as the plain text of § 22a-113n makes clear, any
    recommendation binding on the department, or any
    other state actor, must emanate explicitly from content
    included within an approved harbor management plan.
    The relationship of § 22a-113n to other statutes within
    the broader regulatory framework also supports our
    construction. As stated previously in this opinion, the
    department’s power to review and issue permits for
    individual dock applications is limited by § 22a-361 (h),
    which provides, ‘‘[n]otwithstanding any other provision
    of this section, the [department] shall not issue a certifi-
    cate or permit to authorize any dock or other structure
    in an area that was designated as inappropriate or
    unsuitable for such dock or other structure in a harbor
    management plan approved and adopted pursuant to
    section 22a-113m.’’ (Emphasis added.) Although § 22a-
    361 (h) constrains the department’s authority to issue
    individual dock permits, the language plainly states that
    any limitation must derive from content within
    approved harbor management plans designating an area
    as inappropriate or unsuitable for such a structure.
    Reading § 22a-113n together with § 22a-361 (h), it
    becomes clear that the legislature did not intend to
    empower harbor management commissions with the
    authority to make binding, ad hoc recommendations
    on individual dock placements, unless such recommen-
    dations are provided for within a preexisting, approved
    harbor management plan.
    Finally, § 22a-113m, which describes the process by
    which the department approves a harbor management
    plan, lends further support to our conclusion. Indeed,
    § 22a-113m provides that a harbor management plan
    cannot ‘‘be adopted by ordinance by the legislative body
    of each municipality’’ until it is approved by the depart-
    ment. Likewise, § 22a-113m provides that harbor man-
    agement plans are subject to the department’s annual
    review, ensuring that the department maintains contin-
    uous oversight over the content and execution of the
    plan. In light of these procedural requirements, it would
    make little sense for the legislature to have intended
    that harbor management commissions are empowered
    to make binding recommendations concerning subject
    matter not included in an approved harbor management
    plan. The more logical reading, as the court aptly deter-
    mined, is that § 22a-113n bestows harbor management
    commissions with the authority to make ‘‘plan recom-
    mendations approved by the state binding on the state
    . . . .’’ Accordingly, § 22a-113n (b) is an enforcement
    mechanism for recommendations made pursuant to
    harbor management plans that already have received
    department approval as described in § 22a-113m. Sec-
    tion 22a-113n (b), therefore, does not provide the com-
    mission with a sweeping veto power over the depart-
    ment’s dock permitting authority but, rather, bars the
    department from making arbitrary regulatory decisions
    within the commission’s jurisdiction, or from revoking
    the commission’s authority to regulate preapproved
    activities, without a good cause showing as to ‘‘why a
    different action should be taken.’’
    The plain language of § 22a-113n notwithstanding,
    the intervening plaintiffs contend that our construction
    would lead to absurd or unworkable results. Specifi-
    cally, they argue that requiring harbor management
    commissions to include provisions in harbor manage-
    ment plans concerning individual dock placements
    would necessitate that those commissions ‘‘[anticipate
    and address] . . . every possible scenario for every
    potential permit application that could be filed with
    [the department] for regulatory approval . . . .’’ The
    legislature, however, has already spoken on this issue
    by promulgating § 22a-361 (h), which provides in rele-
    vant part that the department ‘‘shall not issue a certifi-
    cate or permit to authorize any dock or other structure
    in an area that was designated as inappropriate or
    unsuitable for such dock or other structure in a harbor
    management plan approved and adopted pursuant to
    section 22a-113m.’’ (Emphasis added.) The plain text
    of § 22a-361 (h) makes clear that the legislature
    intended that harbor management commissions identify
    within harbor management plans areas that they con-
    sider to be inappropriate or unsuitable for dock place-
    ment. Accordingly, harbor management commissions
    are free to set forth criteria concerning individual dock
    placement that become binding on the department once
    the plan is approved, unless the department can show
    good cause as to why such criteria should not control.
    Simply because harbor management commissions are
    not given a broad veto power over individual dock per-
    mits, when such dock permits are not within an area
    deemed inappropriate or unsuitable, does not render
    the plain text of § 22a-113n unworkable. See Rivers v.
    New Britain, 
    288 Conn. 1
    , 17, 
    950 A.2d 1247
     (2008)
    (defining ‘‘unworkable’’ as ‘‘not capable of being put
    into practice successfully’’ (internal quotation marks
    omitted)).27
    We therefore conclude that the plain text of § 22a-
    113n, as well as its relationship to other statutes, autho-
    rizes harbor management commissions to make recom-
    mendations that are binding on the department only
    when such recommendations arise from content
    already included in an approved harbor management
    plan. Because the Greenwich Harbor Management Plan
    does not discuss the permitting or placement of individ-
    ual docks, the intervening plaintiffs’ claim must fail.
    II
    AC 44547
    We now turn to the plaintiff’s claims on appeal, which
    concern the court’s conclusion that the department and
    the hearing officer ruled correctly on the plaintiff’s envi-
    ronmental claims during the administrative proceedings
    below.28 The plaintiff claims that the court improperly
    concluded that (1) under CEPA, the department applied
    the correct burdens of proof to both her claims and
    those of the defendants during the administrative pro-
    ceedings below and (2) the department’s determination,
    under the tidal wetlands act, that there were no feasible
    and prudent alternatives to the defendants’ dock appli-
    cation was supported by substantial evidence. We are
    not persuaded.
    A
    The plaintiff first claims that, under CEPA, the deputy
    commissioner and the hearing officer applied improper
    burdens of proof as to her and the defendants in the
    administrative proceedings below. Specifically, the
    plaintiff contends that (1) the hearing officer’s conclu-
    sion, which subsequently was affirmed by the deputy
    commissioner, that the plaintiff lacked standing as a
    party intervenor under § 22a-3a-6 (k) (1) (B) of the
    regulations caused the hearing officer to incorrectly
    apply to the plaintiff the burden of proof set forth in
    § 22a-19 concerning environmental intervenors, and (2)
    the hearing officer and the deputy commissioner
    improperly held the plaintiff to a higher burden of proof
    than is required under § 22a-19 and wrongly concluded
    that the defendants were not required to demonstrate
    the absence of feasible alternatives to their proposed
    dock. We disagree with each of the plaintiff’s arguments
    and will address them in turn.
    1
    As an initial matter, the plaintiff contends that the
    hearing officer and the department erred in concluding
    that she had failed to demonstrate standing as an
    intervening party, pursuant to § 22a-3a-6 (k) (1) (B) of
    the regulations, and, therefore, improperly confined her
    participation in the administrative proceedings to that
    of an environmental intervenor under § 22a-19. She
    argues that the court’s determination that she had prop-
    erly alleged classical aggrievement during the adminis-
    trative appeal ‘‘reversed’’ the hearing officer’s determi-
    nation that she had standing to allege only
    environmental claims under § 22a-19 during the admin-
    istrative proceedings below. Accordingly, the plaintiff
    argues that the hearing officer applied to her the incor-
    rect burden of proof because ‘‘she should not have been
    required to prove anything under § 22a-19 because she
    should not have been required to resort to the statute
    as a basis for her intervention.’’
    We conclude that the plaintiff never properly raised
    the issue concerning the hearing officer’s alleged
    improper refusal to grant her intervening party status
    pursuant to § 22a-3a-6 (k) (1) (B) of the regulations
    on administrative appeal before the Superior Court.
    Rather, the plaintiff’s argument on appeal confuses the
    court’s determination that she had demonstrated both
    classical and statutory aggrievement sufficient to
    invoke the subject matter jurisdiction of the court with
    the hearing officer’s determination that she had failed
    to demonstrate standing as an intervening party pursu-
    ant to § 22a-3a-6 (k) (1). See Mayer v. Historic District
    Commission, 
    325 Conn. 765
    , 772, 
    160 A.3d 333
     (2017)
    (‘‘[P]leading and proof of aggrievement are prerequi-
    sites to the trial court’s jurisdiction over the subject
    matter of a plaintiff’s appeal. . . . [I]n order to have
    standing to bring an administrative appeal, a person
    must be aggrieved. . . . Two broad yet distinct catego-
    ries of aggrievement exist, classical and statutory.’’
    (Internal quotation marks omitted.)). The plaintiff never
    claimed during the administrative appeal that the hear-
    ing officer improperly concluded that she had failed to
    properly demonstrate intervening party status under
    § 22a-3a-6 (k) (1) (B). Moreover, the plaintiff pleaded
    different factual allegations in her complaint to the
    Superior Court than she did in her motion to intervene
    before the hearing officer during the administrative pro-
    ceedings. It is well settled that ‘‘[o]ur appellate courts,
    as a general practice, will not review claims made for
    the first time on appeal. . . . This rule applies to
    appeals from administrative proceedings . . . .’’ (Cita-
    tion omitted; internal quotation marks omitted.)

    210 Conn. App. 836
    , 853,
    
    271 A.3d 700
     (2022). Accordingly, we decline to review
    the plaintiff’s claim that the court’s ruling as to her
    standing overruled, sub silentio, the hearing officer’s
    determination that she had failed to allege facts suffi-
    cient to confer intervening party status on her pursuant
    to § 22a-3a-6 (k) (1) (B).
    2
    The plaintiff next claims that the hearing officer and
    the deputy commissioner applied incorrect burdens of
    proof to the plaintiff and to the defendants in the admin-
    istrative proceedings below. Specifically, the plaintiff
    contends that the hearing officer and the deputy com-
    missioner held her to a higher standard of proof than
    was required by CEPA and improperly concluded that
    the defendants did not have the burden of proving the
    absence of alternative feasible designs. We disagree.
    The following additional facts and procedural history
    are relevant to our resolution of the plaintiff’s claim. In
    the proposed final decision, the hearing officer clarified
    that both the plaintiff, as an environmental intervenor
    pursuant to § 22a-19, and the defendants, as applicants
    for an individual dock permit pursuant to applicable
    portions of the coastal management act; the structures,
    dredging and fill act; and the tidal wetlands act, carried
    separate burdens of proof.
    Regarding the plaintiff’s burden, the hearing officer
    clarified that, as an intervening party pursuant to § 22a-
    19, the plaintiff was required to produce evidence that
    pollution, impairment, or destruction of the public trust
    she complained of was reasonably likely to occur and
    that if the pollution, impairment or destruction did
    occur, it would be unreasonable. Applying this frame-
    work, the hearing officer made the following conclu-
    sions. First, the hearing officer determined that,
    because the proposed dock was ‘‘in character with a
    heavily developed residential shoreline with a large
    number of residential docks,’’ the plaintiff had failed
    to demonstrate that the dock would have a negative
    visual impact on the area of Greenwich Cove where
    the dock would be located. Second, the hearing officer,
    crediting the expert testimony offered by both the
    defendants and the department, concluded that pedes-
    trian access to the proposed dock was unlikely ‘‘to
    result in the unreasonable destruction of that coastal
    resource.’’ Third, the hearing officer determined that
    the plaintiff had failed to offer sufficient evidence sup-
    porting her allegation that using a motorboat near the
    proposed dock would negatively impact the tidal wet-
    lands.29 The hearing officer concluded, accordingly, that
    the plaintiff had failed to meet her burden of proof.
    The hearing officer then addressed the defendants’
    burden of proof concerning the dock application. The
    hearing officer clarified that the defendants carried the
    burden of proving, by a preponderance of the evidence,
    that their application satisfied statutory and regulatory
    criteria set forth in the coastal management act; in the
    structures, dredging and fill act; in the tidal wetlands
    act; and in §§ 22a-30-1 through 22a-30-17 of the Regula-
    tions of Connecticut State Agencies. Citing the expert
    testimony submitted in support of the defendants’ appli-
    cation, the hearing officer concluded: ‘‘[T]he construc-
    tion of the proposed structure, will provide the [defen-
    dants] with reasonable access to the water while
    balancing intrusions into the public trust and limiting
    environmental impacts. The application and evidence
    presented during the hearing support the assertion that
    the [defendants’] exercise of their littoral right to wharf
    out can be achieved while minimizing impacts to coastal
    resources, wildlife, navigation, and coastal sedimenta-
    tion and erosion patterns. . . . The application and evi-
    dence placed in the evidentiary record indicate that the
    proposed structure will have no impact on the health
    or welfare of the public or to any fisheries, wildlife or
    sediments. The record supports the factual findings and
    conclusions based on those findings that potential envi-
    ronmental impacts from the proposed project have been
    sufficiently minimized and that the project is consistent
    with applicable policies regarding coastal resources
    management, satisfying the [defendants’] burden in this
    matter.’’
    In her administrative appeal before the Superior
    Court, the plaintiff claimed that the hearing officer
    imposed on her an incorrect burden of proof. Specifi-
    cally, the plaintiff alleged that ‘‘[t]he [department] and
    the hearing officer . . . confused the requirements of
    sufficiently pleading a basis for statutory standing under
    § 22a-19 with the requirements of proof under [General
    Statutes §§] 22a-16 and 22a-17 of CEPA.’’ The plaintiff
    also alleged that the hearing officer improperly con-
    cluded that the defendants had met their burden of
    proof concerning the dock application and had ‘‘effec-
    tively shifted’’ that burden to the plaintiff.
    At oral argument before the Superior Court, the plain-
    tiff conceded that there were two different burdens of
    proof, one for the defendants as applicants, and one
    for the plaintiff as an environmental intervenor. The
    plaintiff alleged, however, that the department, in the
    final decision, improperly placed the burden on her to
    prove that there was a lack of feasible alternatives to
    the defendants’ proposed dock, when it should have
    placed the burden on the defendants to prove the lack
    of feasible alternatives.
    In its memorandum of decision, the court rejected
    the plaintiff’s arguments, concluding instead that the
    hearing officer properly had applied the correct burdens
    of proof to the parties. With regard to the feasible alter-
    natives argument, the court clarified that ‘‘[f]easible
    alternatives are part of the process in two different
    ways. Under . . . § 22a-19 (b), if [the plaintiff] had
    proved her pollution claim [the department] would have
    had to deny the permit if there was a ‘feasible and
    prudent alternative.’ With [the plaintiff] not having
    proved her pollution claim, to grant the permit, [§ 22a-
    30-10 of the Regulations of Connecticut State Agencies]
    still required [the department] to find [that] there was
    ‘no alternative for accomplishing the applicant’s objec-
    tives which is technically feasible and would further
    minimize adverse impacts.’ . . . Nowhere did the hear-
    ing officer suggest that [the plaintiff] bore any burden
    in this regard, and nowhere did the [department] in
    the final decision affirming the hearing officer suggest
    anything different.’ ’’ The court concluded, accordingly,
    that the department and the hearing officer did not
    misapply the competing burdens of proof in the pro-
    posed final decision or in the final decision.
    On appeal, the plaintiff makes two interrelated argu-
    ments in support of her claim that the court improperly
    concluded that the department and the hearing officer
    applied the correct burdens of proof during the adminis-
    trative hearings below. First, she contends that both
    the department and the hearing officer ‘‘confused the
    requirements of sufficiently pleading a basis for statu-
    tory standing under [§] 22a-19 with the requirements
    of proof required in a direct environmental action under
    [§§ 22a-16 and 22a-17]’’ of CEPA. In essence, the plain-
    tiff argues that environmental intervenors, acting pursu-
    ant to § 22a-19, carry a lower evidentiary burden to
    demonstrate environmental harm than do litigants
    bringing a direct environmental action under §§ 22a-16
    and 22a-17, even after the intervenor has been made
    party to the litigation.30 Second, the plaintiff contends
    that the court improperly concluded that the defendants
    were required to produce evidence of the absence of
    feasible alternatives only if the plaintiff made a prima
    facie showing of pollution or environmental harm under
    § 22a-19. We are not persuaded.
    The plaintiff’s first argument is premised on a misun-
    derstanding of the law concerning the burden of proof
    required to demonstrate standing as an intervening
    party, pursuant to § 22a-19 (a), and the burden of proof
    required of intervening parties, already joined in the
    litigation, to produce evidence of unreasonable pollu-
    tion that requires the department to consider feasible
    alternatives under § 22a-19 (b). Because the plaintiff’s
    argument presents a question of statutory interpretation
    concerning the burdens of proof required of intervening
    parties under § 22a-19, our review is plenary. See, e.g.,
    Waterbury v. Washington, 
    260 Conn. 506
    , 546–47, 
    800 A.2d 1102
     (2002).
    As an initial matter, § 22a-19 (a) sets forth the plead-
    ing requirements for parties seeking to intervene on
    environmental grounds in administrative or licensing
    proceedings. In order to demonstrate standing under
    § 22a-19 and therefore be made a party to the relevant
    proceeding, a party must file a verified pleading that
    contains ‘‘specific factual allegations setting forth the
    nature of the alleged unreasonable pollution, impair-
    ment or destruction of the public trust in air, water
    or other natural resources of the state and should be
    sufficient to allow the reviewing authority to determine
    from the verified pleading whether the intervention
    implicates an issue within the reviewing authority’s
    jurisdiction.’’ General Statutes § 22a-19 (a) (2); see also
    Nizzardo v. State Traffic Commission, 
    259 Conn. 131
    ,
    164–65, 
    788 A.2d 1158
     (2002) (‘‘[A] petition for interven-
    tion filed under § 22a-19 must contain specific factual
    allegations setting forth the environmental issue that
    the intervenor intends to raise. The facts contained
    therein should be sufficient to allow the agency to deter-
    mine from the face of the petition whether the interven-
    tion implicates an issue within the agency’s jurisdic-
    tion.’’).
    By contrast, § 22a-19 (b) delineates when the agency
    overseeing the administrative proceeding must con-
    sider feasible alternatives after the intervenor has
    already satisfied the threshold standing requirement set
    forth in § 22a-19 (a) and has been made party to the
    proceedings. Specifically, § 22a-19 (b) provides that,
    ‘‘[i]n any administrative, licensing or other proceeding,
    the agency shall consider the alleged unreasonable pol-
    lution, impairment or destruction of the public trust
    in the air, water or other natural resources of the state
    and no conduct shall be authorized or approved which
    does, or is reasonably likely to, have such effect as long
    as, considering all relevant surrounding circumstances
    and factors, there is a feasible and prudent alternative
    consistent with the reasonable requirements of the pub-
    lic health, safety and welfare.’’ (Emphasis added.)
    Our Supreme Court previously has interpreted § 22a-
    19 (b) to require that agencies overseeing the adminis-
    trative proceedings consider feasible alternatives only
    after they first determine that the defendant’s conduct
    is, or is likely to, cause an unreasonable environmental
    impact. In Paige v. Town Plan & Zoning Commission,
    
    235 Conn. 448
    , 
    668 A.2d 340
     (1995), our Supreme Court
    determined that intervening plaintiffs acting pursuant
    to § 22a-19 did not need to produce evidence demon-
    strating that the ‘‘natural resources’’ they sought to pro-
    tect had economic value. Id., 461–62. In so holding, our
    Supreme Court considered the argument that abandon-
    ing the economic value test would lead to agencies
    being required, under § 22a-19 (b), to consider feasible
    alternatives in every proceeding in which a party inter-
    vened pursuant to § 22a-19 (b). Id., 462. Our Supreme
    Court rejected that argument, concluding that, ‘‘[b]y its
    plain terms . . . § 22a-19 (b) requires the consider-
    ation of alternative plans only where the commission
    first determines that it is reasonably likely that the
    project would cause unreasonable pollution, impair-
    ment or destruction of the public trust in the natural
    resource at issue. . . . In view of the factors and stan-
    dards that govern the determination in each case, any
    fear that a broad definition will cause alternative plans
    to be required in virtually every case is plainly unwar-
    ranted.’’ (Citations omitted; emphasis altered; internal
    quotation marks omitted.) Id., 462–63.
    This court later applied our Supreme Court’s con-
    struction of § 22a-19 (b) in Evans v. Plan & Zoning
    Commission, 
    73 Conn. App. 647
    , 
    808 A.2d 1151
     (2002).
    In Evans, the plaintiffs intervened, pursuant to § 22a-
    19 (a), in an application proceeding before the Plan and
    Zoning Commission of the Town of Glastonbury for
    subdivision-resubdivision approval and a rear lot spe-
    cial permit. Id., 649. On appeal to this court, the plaintiffs
    claimed that ‘‘the commission failed to follow the statu-
    tory requirements of § 22a-19 by not considering feasi-
    ble and prudent alternatives to the proposed applica-
    tion.’’ Id., 656. In response, the defendants argued that
    § 22a-19 requires the consideration of alternatives only
    if the proposed project involves conduct reasonably
    likely to cause unreasonable impairment to a natural
    resource. Id., 657. This court agreed with the defen-
    dants, concluding that, ‘‘ [b]y its plain terms . . . § 22a-
    19 (b) requires the consideration of alternative plans
    only where the commission first determines that it is
    reasonably likely that the project would cause unrea-
    sonable pollution, impairment or destruction of the
    public trust in the natural resource at issue. . . .
    [O]nce the commission made no finding of unreason-
    able impairment of natural resources, it no longer had
    an obligation to consider alternative plans.’’) (Cita-
    tions omitted; emphasis altered.) Id., 657–58.
    Both our Supreme Court’s decision in Paige and this
    court’s decision in Evans demonstrate that properly
    alleging statutory standing under § 22a-19 (a) to be
    made party to an administrative proceeding and produc-
    ing evidence of unreasonable environmental impair-
    ment sufficient to require that the agency consider feasi-
    ble alternatives under § 22a-19 (b), are governed by two
    separate burdens of proof. Indeed, § 22a-19 (a) requires
    that an intervening plaintiff set forth only a ‘‘ ‘colorable
    claim’ ’’ of unreasonable pollution, impairment or
    destruction of the environment, sufficient to survive a
    motion to dismiss. Finley v. Inland Wetlands Commis-
    sion, 
    289 Conn. 12
    , 35, 
    959 A.2d 569
     (2008). An interven-
    ing plaintiff ‘‘ ‘need not prove his case’ ’’ in order to
    successfully plead intervenor standing pursuant to
    § 22a-19 (a). Id. By contrast, the decisions in Paige and
    Evans make clear that an agency’s consideration of
    feasible alternatives, pursuant to § 22a-19 (b), is trig-
    gered only by the agency’s preliminary finding of an
    unreasonable impairment of natural resources. See
    Paige v. Town Plan & Zoning Commission, supra, 
    235 Conn. 462
    –63; Evans v. Plan & Zoning Commission,
    supra, 
    73 Conn. App. 657
    . It follows that such a finding
    must be predicated on evidence produced by the
    intervening party alleging an unreasonable environmen-
    tal impairment.31 See Reycling, Inc. v. Commissioner
    of Energy & Environmental Protection, 
    179 Conn. App. 127
    , 141, 
    178 A.3d 1043
     (2018) (‘‘The substantial evi-
    dence rule governs judicial review of administrative
    fact-finding under the UAPA. . . . An administrative
    finding is supported by substantial evidence if the
    record affords a substantial basis of fact from which
    the fact in issue can be reasonably inferred.’’ (Internal

    Moreover, we note that the structure of § 22a-19 also
    supports our conclusion that environmental intervenors
    must do more than establish statutory standing in order
    to trigger the agency’s consideration of feasible alterna-
    tives under § 22a-19 (b). As stated previously, § 22a-19
    (a) details the pleading requirements for an intervening
    party to successfully allege statutory standing. By con-
    trast, § 22a-19 (b) details when the administrative
    agency presiding over the proceeding must consider
    feasible alternatives. Under the plaintiff’s interpreta-
    tion, the requirements necessary to demonstrate statu-
    tory standing and the burden of proof required to trigger
    consideration of feasible alternatives would collapse
    into one another. In interpreting § 22a-19, we are mind-
    ful that ‘‘[i]t is a basic tenet of statutory construction
    that the legislature [does] not intend to enact meaning-
    less provisions. . . . [I]n construing statutes, we pre-
    sume that there is a purpose behind every sentence,
    clause, or phrase used in an act and that no part of a
    statute is superfluous. . . . Because [e]very word and
    phrase [of a statute] is presumed to have meaning . . .
    [a statute] must be construed, if possible, such that no
    clause, sentence or word shall be superfluous, void
    or insignificant.’’ (Internal quotation marks omitted.)

    Connecticut, Inc., 
    302 Conn. 464
    , 474, 
    28 A.3d 958
    (2011). If demonstrating statutory standing under § 22a-
    19 was all that was required to trigger the agency’s
    consideration of feasible alternatives, § 22a-19 (b)
    would be rendered superfluous. We decline to construe
    § 22a-19 in such a manner.33
    Second, the plaintiff argues that the court improperly
    concluded that the defendants were required to produce
    the absence of feasible alternatives only if the plaintiff
    made a prima facie showing of pollution or environmen-
    tal harm under § 22a-19. We conclude, in light of our
    determination that an agency may consider feasible
    alternatives under § 22a-19 (b) only after it first deter-
    mines that the defendant’s proposed action causes, or is
    reasonably likely to cause, unreasonable environmental
    impairment, that the plaintiff’s argument must fail.
    Indeed, both the hearing officer and the deputy commis-
    sioner concluded that the plaintiff had failed to set forth
    substantial evidence demonstrating that the defendants’
    proposed dock would, or was reasonably likely to,
    result in unreasonable environmental harm. Accord-
    ingly, there was no requirement for the defendants to
    produce, or for the department to consider, feasible
    alternatives. Cf. Paige v. Town Plan & Zoning Commis-
    sion, supra,

    –63; Evans v. Plan & Zoning
    Commission, supra, 
    73 Conn. App. 657
    .
    B
    The plaintiff’s final claim is that the court improperly
    concluded that the department’s determination, pursu-
    ant to the tidal wetlands act, that there were no feasible
    and prudent alternatives to the defendants’ proposed
    structure was supported by substantial evidence. We
    disagree.
    ‘‘[T]he substantial evidence rule governs judicial
    review of administrative fact-finding under [the UAPA].
    General Statutes § 4-183 (j) (5) and (6). Substantial evi-
    dence exists if the administrative record affords a sub-
    stantial basis of fact from which the fact in issue can
    be reasonably inferred. . . . This substantial evidence
    standard is highly deferential and permits less judicial
    scrutiny than a clearly erroneous or weight of the evi-
    dence standard of review. . . . The reviewing court
    must take into account [that there is] contradictory
    evidence in the record . . . but the possibility of draw-
    ing two inconsistent conclusions from the evidence
    does not prevent an administrative agency’s finding
    from being supported by substantial evidence . . . .
    The burden is on the [plaintiff] to demonstrate that the
    [department’s] factual conclusions were not supported
    by the weight of substantial evidence on the whole
    record. . . .
    ‘‘Judicial review of an administrative agency decision
    requires a court to determine whether there is substan-
    tial evidence in the administrative record to support
    the agency’s findings of basic fact and whether the
    conclusions drawn from those facts are reasonable.
    . . . This so-called substantial evidence rule is similar
    to the sufficiency of the evidence standard applied in
    judicial review of jury verdicts, and evidence is suffi-
    cient to sustain an agency finding if it affords a substan-
    tial basis of fact from which the fact in issue can be
    reasonably inferred. . . . [I]t imposes an important
    limitation on the power of the courts to overturn a
    decision of an administrative agency . . . and [pro-
    vides] a more restrictive standard of review than stan-
    dards embodying review of weight of the evidence or
    clearly erroneous action. . . . The United States
    Supreme Court, in defining substantial evidence . . .
    has said that it is something less than the weight of
    the evidence, and [that] the possibility of drawing two
    inconsistent conclusions from the evidence does not
    prevent an administrative agency’s finding from being
    supported by substantial evidence. . . . [T]he credibil-
    ity of witnesses and the determination of factual issues
    are matters within the province of the administrative
    agency. . . . As with any administrative appeal, our
    role is not to reexamine the evidence presented to the
    [agency] or to substitute our judgment for the agency’s
    expertise, but, rather, to determine whether there was
    substantial evidence to support its conclusions. . . .
    ‘‘In reviewing decisions made by an administrative
    agency, a reviewing court must sustain the agency’s
    determination if an examination of the record discloses
    evidence that supports any one of the reasons given.
    . . . The evidence, however, to support any such rea-
    son must be substantial . . . .’’ (Citations omitted;

    In contrast to CEPA, which requires that the depart-
    ment consider feasible alternatives only when it first
    finds that the defendants’ proposed structure was rea-
    sonably likely to result in unreasonable environmental
    impact; see part II A 1 of this opinion; see also Paige
    v. Town Plan & Zoning Commission, supra, 
    235 Conn. 462
    –63; Evans v. Plan & Zoning Commission, supra,

    ; the consideration of feasible alterna-
    tives under the tidal wetlands act and its related regula-
    tions is a requirement independent of any finding of
    impairment or pollution. Section 22a-30-10 (b) of the
    regulations provides, ‘‘[i]n order to make a determina-
    tion that a proposed activity will preserve the wetlands
    of the state and not lead to their despoliation and
    destruction the commissioner shall, as applicable, find
    that: (1) There is no alternative for accomplishing the
    applicant’s objectives which is technically feasible and
    would further minimize adverse impacts . . . .’’
    On the basis of our review of the entire record, we
    conclude that there was substantial evidence to support
    the hearing officer’s finding concerning the lack of feasi-
    ble alternatives to the proposed structure. In determin-
    ing that there were no prudent and feasible alternatives
    to the proposed structure, the hearing officer noted
    that department staff considered and rejected fourteen
    alternative designs to the structure before ultimately
    concluding that the approved structure would have the
    least adverse impact on the surrounding tidal wetlands.
    See Connecticut Building Wrecking Co. v. Carothers,
    
    218 Conn. 580
    , 593, 
    590 A.2d 447
     (1991) (‘‘[a]n agency
    composed of [experts] is entitled . . . to rely on its
    own expertise within the area of its professional compe-
    tence’’ (internal quotation marks omitted)).
    In addition, the hearing officer relied on the expert
    testimony of Jacobson, the department’s permit analyst,
    and Warren, an expert in coastal resources and tidal
    wetlands ecology, both of whom testified that the pro-
    posed structure would have minimal impact on the tidal
    wetlands. See River Bend Associates, Inc. v. Conserva-
    tion & Inland Wetlands Commission, 
    269 Conn. 57
    ,
    78, 
    848 A.2d 395
     (2004) (‘‘Determining what constitutes
    an adverse impact on a wetland is a technically complex
    issue. . . . Inland wetlands agencies commonly rely on
    expert testimony in making such a finding.’’ (Citation
    omitted.)). Specifically, Jacobson testified that the pro-
    posed structure would comply with the requirements
    set forth in § 22a-28, namely, that the proposed struc-
    ture would not alter the surrounding ecosystem or
    adversely affect public health and welfare. Likewise,
    Warren testified that the defendants’ proposed activi-
    ties, such as operating a motorboat near the proposed
    structure and walking through the high marsh to access
    the proposed structure, would not have an appreciable
    impact on the tidal wetlands.
    Although the plaintiff also presented expert testi-
    mony in support of her contention that the proposed
    dock would negatively impact the surrounding tidal
    wetlands, the hearing officer was well within his discre-
    tion to credit the department’s and the defendants’
    experts over the plaintiff’s expert. See, e.g., Goldstar
    Medical Services, Inc. v. Dept. of Social Services, 
    288 Conn. 790
    , 830, 
    955 A.2d 15
     (2008) (‘‘It is well established
    that it is the exclusive province of the trier of fact to
    make determinations of credibility, crediting some, all,
    or none of a given witness’ testimony. . . . [A]n admin-
    istrative agency is not required to believe any witness,
    even an expert.’’ (Citation omitted; internal quotation
    marks omitted.)). Moreover, it is well settled that, even
    when there is conflicting expert testimony, ‘‘evidence
    is sufficient to sustain an agency finding if it affords a
    substantial basis in fact from which the fact in issue
    can be reasonably inferred. . . . [T]he possibility of
    drawing two inconsistent conclusions from evidence
    does not prevent [a determination] from being sup-
    ported by substantial evidence.’’ (Internal quotation
    marks omitted.) Samperi v. Inland Wetlands Agency,
    
    226 Conn. 579
    , 588, 
    628 A.2d 1286
     (1993). Accordingly,
    we conclude that the department’s determination that
    there were no feasible alternatives to the proposed
    structure was supported by substantial evidence.34
    The plaintiff further argues that the proposed struc-
    ture is an improper exercise of the defendants’ littoral
    rights. In particular, the plaintiff contends that the pro-
    posed structure must ‘‘[extend] from [the] upland,’’
    rather than begin past the median high water line,
    existing ‘‘entirely upon land of the state held in trust
    for the public, without any contact whatsoever with
    any property owned by [the defendants].’’
    Littoral rights are ‘‘the rights that shoreline owners
    possess to make exclusive use of the land lying seaward
    of the mean high water mark. . . . [O]wners of . . .
    upland [appurtenant to bodies of water] have the exclu-
    sive, yet qualified, right and privilege to . . . wharf out
    from the owner’s land in a manner that does not inter-
    fere with free navigation.’’ (Citation omitted; internal
    quotation marks omitted.) Caminis v. Troy, 
    300 Conn. 297
    , 299 n.2, 
    12 A.3d 984
     (2011); see also Rochester v.
    Barney, 
    117 Conn. 462
    , 468, 
    169 A. 45
     (1933) (‘‘The
    owner of the adjoining upland has certain exclusive
    yet qualified rights and privileges in the waters and
    submerged land adjoining his upland. He has the exclu-
    sive privilege of wharfing out and erecting piers over
    and upon such soil and of using it for any purpose
    which does not interfere with navigation, and he may
    convey these privileges separately from the adjoining
    land. He also has the right of accretion, and generally
    of reclamation, and the right of access by water to and
    from his upland.’’).
    Although the plaintiff argues that the right to wharf
    permits applicants to erect only structures that ‘‘con-
    nect’’ to the upland, she has failed to produce any
    authority standing for that proposition. Indeed, our
    Supreme Court previously has rejected the notion that
    the ‘‘right of wharfage . . . is an inseparable incident
    or accessory to the upland, in such a sense that it inheres
    in, and is a part of, such upland itself,’’ concluding
    instead that the right to wharf, like other property rights,
    is freely alienable. Simons v. French, 
    25 Conn. 346
    , 352
    (1856). Considering the plain language in Simons that
    the right to wharf is not ‘‘part of’’ the upland itself,
    along with our Supreme Court’s conclusion that the
    owner of the upland property is free to transfer the
    right to wharf to another party, it would make little
    sense to require that any structure providing access
    to navigable waters must extend from the upland or
    connect to a structure extending from the upland.
    Rather, as we previously have stated, an applicant for
    a dock permit bears the burden of demonstrating, by
    a preponderance of the evidence, that the proposed
    structure complies with the relevant statutory schemes,
    namely, the tidal wetlands act; the structures, dredging
    and fill act; and the coastal management act. Accord-
    ingly, the hearing officer correctly determined that,
    ‘‘[w]hile the proposed dock does not match that more
    typical design, there is no requirement of statute or
    common law requiring that it must. The [defendants
    have] the right to use the littoral area to access the
    water, provided that, when balanced with the policies
    in the coastal management act, the exercise of access
    is reasonable, and other relevant statutes and regula-
    tions are satisfied.’’ Because the hearing officer’s deter-
    mination that the defendants’ application satisfied the
    applicable regulatory and statutory criteria is supported
    by substantial evidence in the record, we conclude that
    the plaintiff’s claim must fail.
    The judgment is affirmed.
    In this opinion the other judges concurred.

    Specifically, the proposed structure contained the following features:
    (1) a five foot by twenty foot floating dock, secured by two float restraint
    piles, and equipped with floating steps; (2) a four foot by twenty-six foot
    timber pier, supported by six timber piles, with open-grate decking and
    steel cable handrails; (3) a three foot wide by twenty-three foot long ramp
    extending to the floating dock; and (4) a fifteen foot by fifteen foot boat
    lift with a support stringer and two piles.

    property as well as the limits of municipal jurisdiction for regulating upland

    The defendants had filed an earlier application (first application) with
    the department on August 25, 2014. On December 23, 2014, the department
    responded to the defendants’ application, informing the defendants that
    local zoning regulations would not permit the dock as proposed. Specifically,
    the department explained that ‘‘we have concluded it would be inadvisable
    to allow you to revise the pending application to propose a dock entirely
    waterward of mean high water. In our experience, structures designed to
    avoid upland land use restrictions, whether originating in zoning regulations
    or conservation easements, raise a number of policy issues, and could set
    a precedent encouraging proliferation of docks in inappropriate locations.
    In order to thoroughly evaluate such issues, we believe that the best course
    of action would be for you to withdraw the pending application, and reapply
    at a later date. The new application could then include a written confirmation
    from the appropriate [town] official indicating that there are no municipal
    issues with the dock being installed at mean high water, as well as revised
    consultations with municipal commissions and [department] resource agen-
    cies.’’ The defendants subsequently withdrew the first application and sub-
    mitted the present application in accordance with the department’s proposed
    structural designs.
    5
    Between July 31, 2015, and March 6, 2018, when the department issued
    the tentative determination to approve the application, the department made
    three additional requests for information. The defendants responded to each
    supplemental request. Likewise, in response to comments from department
    staff, the defendants modified the initial design of their proposed dock,
    replacing timber steps with an access ladder at the landward end of the pier.
    Consultants for the defendants prepared many alternative dock designs,
    which were rejected as having a greater environmental impact than the final
    proposed dock. Department staff evaluated and rejected fourteen alternative
    dock designs.

    determines that the regulated activity for which a permit is sought is not
    likely to have a significant impact on the wetland, the commissioner may
    waive the requirement for public hearing after publishing notice, in a newspa-
    per having general circulation in each town wherever the proposed work
    or any part thereof is located, of the commissioner’s intent to waive said
    requirement and of the commissioner’s tentative decision regarding the
    application, except that the commissioner shall hold a hearing on such

    Section 22a-3a-6 (k) (1) (B) of the Regulations of Connecticut State

    strate that (i) his [or her] legal rights, duties or privileges will or may
    reasonably be expected to be affected by the decision in the proceeding,
    (ii) he [or she] will or may reasonably be expected to be significantly
    affected by the decision in the proceeding, or (iii) his [or her] participation
    is necessary to the proper disposition of the proceeding.’’
    10
    General Statutes § 22a-19 provides: ‘‘(a) (1) In any administrative, licens-
    ing or other proceeding, and in any judicial review thereof made available
    by law, the Attorney General, any political subdivision of the state, any
    instrumentality or agency of the state or of a political subdivision thereof,
    any person, partnership, corporation, association, organization or other legal
    entity may intervene as a party on the filing of a verified pleading asserting
    that the proceeding or action for judicial review involves conduct which has,
    or which is reasonably likely to have, the effect of unreasonably polluting,
    impairing or destroying the public trust in the air, water or other natural
    resources of the state. . . .
    ‘‘(2) The verified pleading shall contain specific factual allegations setting
    forth the nature of the alleged unreasonable pollution, impairment or
    destruction of the public trust in air, water or other natural resources of
    the state and should be sufficient to allow the reviewing authority to deter-
    mine from the verified pleading whether the intervention implicates an issue
    within the reviewing authority’s jurisdiction. For purposes of this section,
    ‘reviewing authority’ means the board, commission or other decision-making
    authority in any administrative, licensing or other proceeding or the court
    in any judicial review.
    ‘‘(b) In any administrative, licensing or other proceeding, the agency shall
    consider the alleged unreasonable pollution, impairment or destruction of
    the public trust in the air, water or other natural resources of the state and
    no conduct shall be authorized or approved which does, or is reasonably
    likely to, have such effect as long as, considering all relevant surrounding
    circumstances and factors, there is a feasible and prudent alternative consis-
    tent with the reasonable requirements of the public health, safety and wel-
    fare.’’
    11
    The hearing officer also determined that he could not consider the
    plaintiff’s third argument, concerning the alleged ‘‘proliferation of permit
    applications,’’ because ‘‘[his] review [was] limited to the current conditions
    and the impacts of the proposed structure on those conditions’’ and not
    ‘‘the cumulative impact from structures not built or applied for.’’
    12
    Although written comments concerning the defendants’ application
    were initially due on September 19, 2018, the hearing officer granted the
    commission’s August 8, 2018 request to extend the written comment deadline
    until September 21, 2018.
    13
    The plaintiff subsequently abandoned several of these claims. In her
    brief to the Superior Court, the plaintiff clarified that the issues she was
    pursuing on appeal were limited to the following: (1) the department, in
    the final decision, improperly shifted the burden of proof to the plaintiff to
    demonstrate ‘‘feasible alternatives’’ to the defendants’ proposed dock; (2)
    the department erred in failing to determine whether feasible alternatives
    existed to the proposed dock, including a community dock located near the
    subject property; (3) the department misinterpreted and, therefore, violated
    § 22a-113n by failing to regard the commission’s recommendation in the
    public comment letter concerning the defendants’ proposed dock ‘‘as bind-
    ing.’’
    14
    Practice Book § 9-18, titled, ‘‘Addition or Substitution of Parties; Addi-
    tional Parties Summoned in by Court,’’ provides: ‘‘The judicial authority may
    determine the controversy as between the parties before it, if it can do so
    without prejudice to the rights of others; but, if a complete determination
    cannot be had without the presence of other parties, the judicial authority
    may direct that they be brought in. If a person not a party has an interest
    or title which the judgment will affect, the judicial authority, on its motion,
    shall direct that person to be made a party.’’
    15
    General Statutes § 52-107, titled, ‘‘Additional parties may be summoned
    in,’’ provides: ‘‘The court may determine the controversy as between the
    parties before it, if it can do so without prejudice to the rights of others;
    but, if a complete determination cannot be had without the presence of
    other parties, the court may direct that such other parties be brought in. If
    a person not a party has an interest or title which the judgment will affect,
    the court, on his application, shall direct him to be made a party.’’
    16
    Specifically, the department contended that the hearing officer had
    previously denied the plaintiff’s claim that her legal rights, duties or privileges
    would be affected by the decision in the proceeding and, accordingly, had
    limited her participation to three narrow environmental issues. Because
    the claims subject to the motion to dismiss did not allege ‘‘unreasonable
    impairment, destruction or pollution of the air, water, or natural resources
    of the state,’’ the department contended that those claims exceeded the
    permissible scope of what the plaintiff could claim on appeal.
    17
    The court also reiterated its determination that the plaintiff had standing
    to pursue all of her claims on administrative appeal. In particular, the court
    noted that the plaintiff’s focus on the department’s alleged procedural fail-
    ures during the administrative proceedings, rather than environmental con-
    cerns posed by the defendants’ proposed dock, was part of her trial strategy.
    As such, the court concluded that the plaintiff was not required to challenge
    the department’s environmental findings to have standing on administrative
    appeal. The court then reiterated that the plaintiff adequately had alleged
    both classical and statutory aggrievement.
    18
    The intervening plaintiffs argued, in the alternative, that they were enti-
    tled to permissive intervention should the court determine that they had
    not satisfied their burden of demonstrating intervention as a matter of right.
    19
    In their brief to the Superior Court, the defendants renewed their argu-
    ment that the intervening plaintiffs should not have been made parties to
    the administrative appeal. Specifically, the defendants argued that, because
    the commission never sought to intervene as a party in the administrative
    proceedings, the public comment letter was not ‘‘evidence in the record’’
    upon which the department could decide the defendants’ permit application.
    Accordingly, the defendants argued that the intervening plaintiffs had no
    basis upon which to overturn the department’s decision.
    20
    The Superior Court concluded that the plaintiff was both statutorily
    and classically aggrieved such that all of her claims were properly before
    the court. Because we conclude that the intervening plaintiffs’ standing to
    pursue their § 22a-113n claim was not dependent on the plaintiff’s standing
    to bring the same claim, it is irrelevant for purposes of the present claim
    for us to revisit the court’s determination with respect to the plaintiff’s
    standing. Moreover, for different reasons that are explained in part II of
    this opinion; see footnote 28 of this opinion; it is not necessary for us to
    determine whether the court properly determined that the plaintiff had
    standing to pursue the § 22a-113n claim in her appeal from the department’s
    final decision.
    21
    Although our Supreme Court has never decided the issue, it previously
    has noted that ‘‘[t]he whole point of intervention is to allow the participation
    of persons with interests distinct from those of the original parties; it is
    therefore to be expected that an intervenor’s standing will have a somewhat
    different basis from that of the original plaintiffs.’’ (Emphasis added;
    internal quotation marks omitted.) Franco v. East Shore Development, Inc.,
    
    271 Conn. 623
    , 630, 
    858 A.2d 703
     (2004). We construe this language to be
    consistent with the notion that an intervening party with an independent
    jurisdictional basis may continue to litigate in a proceeding even after the
    original party’s claims have been dismissed.
    22
    General Statutes § 4-175 provides in relevant part: ‘‘(a) If a provision
    of the general statutes, a regulation or a final decision, or its threatened
    application, interferes with or impairs, or threatens to interfere with or
    impair, the legal rights or privileges of the plaintiff and if an agency (1)
    does not take an action required by subdivision (1), (2) or (3) of subsection
    (e) of section 4-176, within sixty days of the filing of a petition for a declara-
    tory ruling, (2) decides not to issue a declaratory ruling under subdivision
    (4) or (5) of subsection (e) of said section 4-176, or (3) is deemed to have
    decided not to issue a declaratory ruling under subsection (i) of said section
    4-176, the petitioner may seek in the Superior Court a declaratory judgment
    as to the validity of the regulation in question or the applicability of the
    provision of the general statutes, the regulation or the final decision in
    question to specified circumstances. The agency shall be made a party to
    the action. . . .’’
    23
    General Statutes § 4-176 provides in relevant part: ‘‘(a) Any person may
    petition an agency, or an agency may on its own motion initiate a proceeding,
    for a declaratory ruling as to the validity of any regulation, or the applicability
    to specified circumstances of a provision of the general statutes, a regulation,
    or a final decision on a matter within the jurisdiction of the agency. . . .
    ‘‘(e) Within sixty days after receipt of a petition for a declaratory ruling,
    an agency in writing shall: (1) Issue a ruling declaring the validity of a
    regulation or the applicability of the provision of the general statutes, the
    regulation, or the final decision in question to the specified circumstances,
    (2) order the matter set for specified proceedings, (3) agree to issue a
    declaratory ruling by a specified date, (4) decide not to issue a declaratory
    ruling and initiate regulation-making proceedings, under section 4-168, on
    the subject, or (5) decide not to issue a declaratory ruling, stating the reasons
    for its action.’’
    24
    The defendants argue that the public comment letter did not specify
    how the proposed structure failed to comply with department policy and
    that the ‘‘the only recommendation in the [public comment letter] is to
    request that [the department] provide a statement of policy about docks
    situated below the [mean high water line].’’ (Emphasis omitted.)
    25
    Section 22a-3a-6 (t) of the Regulations of Connecticut State Agencies
    provides that ‘‘[a]ny person who is not a party or intervenor nor called by
    a party or intervenor as a witness may make an oral or written statement
    at the hearing. Such a person shall be called a speaker. If the hearing officer
    is going to consider a speaker’s statement as evidence or if the speaker
    wants his statement to be considered as evidence, the hearing officer shall
    require that the statement be made under oath or affirmation and shall
    permit the parties and intervenors to cross-examine the speaker and to
    challenge or rebut the statement. A speaker may decline to be cross-exam-
    ined, but the hearing officer shall strike from the record any comments by
    such speaker relating to the subject on which he declines to be cross-
    examined. The hearing officer may control the time and duration of a speak-
    er’s presentation, and may exclude irrelevant, immaterial, or unduly repeti-
    tious comments by a speaker. A speaker shall not be entitled to cross-
    examine parties, intervenors, or other speakers or to object to evidence or
    procedure.’’
    26
    In the proposed final decision, the hearing officer noted: ‘‘While the
    [commission’s] public comment is not evidence in the record . . . I can
    rely on it to guide my inquiry into this matter. It is reasonable to assume
    that, if the [commission] believed that the proposed dock was in an area it
    had identified as inappropriate or unsuitable, it would have included a
    statement to that effect in its comment, for the purpose of guiding my inquiry
    into § 22a-361 (h). In making this assumption, I do not rely on the public
    comment as proof of any particular fact, but instead as a collective statement
    of the [commission], a group with extensive knowledge of, and a vested
    interest in, the [p]lan.’’
    27
    The intervening plaintiffs also contend that the legislative history under-
    lying § 22a-113n cautions against our construction. Because, however, the
    statutory language unambiguously leads us to the conclusion that any recom-
    mendations made by harbor management commissions that are binding on
    the department must emanate from the harbor management plan, we decline
    to consider the extratextual sources on which the intervening plaintiffs rely.
    See, e.g., Wilton Campus 1691, LLC v. Wilton, 
    339 Conn. 157
    , 175–76, 
    260 A.3d 464
     (2021) (‘‘[b]ecause the statute, when read in context, has only one
    reasonable interpretation, the statute is not ambiguous, and we therefore
    do not consider the . . . legislative history or other extratextual sources’’);
    see also General Statutes § 1-2z.
    28
    In addition to the claims we address in this part of the opinion, the
    plaintiff also claims that § 22a-113n empowers harbor management commis-
    sions to make recommendations that are binding on the department concern-
    ing individual dock placements within their jurisdictions. In part I of this
    opinion, we concluded, contrary to the plaintiff’s claim, that § 22a-113n does
    not empower harbor management commissions to make recommendations
    that are binding on the department unless such a recommendation is made
    pursuant to an approved harbor management plan. The department and the
    defendants argue that the plaintiff lacks standing to pursue the § 22a-113n
    claim because she is neither classically nor statutorily aggrieved by any
    decision concerning the proper construction of that provision.
    We recognize the general rule that aggrievement implicates this court’s
    subject matter jurisdiction and that ‘‘[a] possible absence of subject matter
    jurisdiction must be addressed and decided whenever the issue is raised
    . . . .’’ (Internal quotation marks omitted.) In re Ava W., 
    336 Conn. 545
    ,
    553, 
    248 A.3d 675
     (2020). In the present case, however, our prior resolution,
    in part I of this opinion, of the same legal issue that the plaintiff raises here
    makes it unnecessary for us to consider whether we have jurisdiction to
    consider the plaintiff’s claim. Regardless of whether the plaintiff is aggrieved
    by the determination regarding § 22a-113n, our prior resolution of the issue
    defeats her claim.
    29
    Specifically, the hearing officer concluded that the plaintiff’s allegations
    that motorboat access would result in ‘‘prop dredging’’ or negative ‘‘wave
    action’’ were too speculative to satisfy her burden.
    30
    Specifically, the plaintiff contends that the trial court improperly failed
    to consider her claim that the deputy commissioner relied on ‘‘fictitious’’
    case law in determining that the defendants were not required to produce
    evidence of the absence of feasible alternatives. The plaintiff’s contention
    stems from a citation error in the final decision wherein the deputy commis-
    sioner purported to quote from Waterbury v. Washington, 
    260 Conn. 506
    ,
    
    800 A.2d 1102
     (2002), but actually was paraphrasing language from that case
    describing the burden-shifting framework set forth in § 22a-17. The plaintiff
    alleges that the deputy commissioner’s reliance on Waterbury was improper
    because that case involved a direct environmental action under § 22a-16
    and not an environmental intervenor action pursuant to § 22a-19, such as
    in the present case. Accordingly, the plaintiff contends that the burden-
    shifting framework set forth in § 22a-17, which governs direct actions
    brought pursuant to § 22a-16, should not have been applied in the pres-
    ent case.
    Even if we assume, however, that the deputy commissioner incorrectly
    applied the burden-shifting framework set forth in § 22a-17 against the plain-
    tiff instead of against the defendants, the plaintiff is unable to demonstrate
    how she was harmed thereby. For the reasons that follow, we conclude
    that the hearing officer and deputy commissioner properly determined that
    the plaintiff was required to produce evidence that the defendants’ proposed
    structure was reasonably likely to result in unreasonable pollution before
    the department was required to consider feasible alternatives. See General
    Statutes § 22a-19 (b). Because the plaintiff did not prove that unreasonable
    pollution was reasonably likely to result from the proposed structure, there
    was no basis for the department to consider feasible alternatives.
    31
    We note that this interpretation aligns with the statutory burden-shifting
    framework that governs direct environmental actions under CEPA. See
    General Statutes §§ 22a-16 and 22a-17. To bring a direct environmental action
    in the Superior Court under § 22a-16, a plaintiff need allege only a colorable
    claim that ‘‘unreasonable pollution, impairment or destruction of a natural
    resource will probably result from the challenged activities unless remedial
    measures are taken.’’ (Internal quotation marks omitted.) Burton v. Commis-
    sioner of Environmental Protection, 
    291 Conn. 789
    , 810, 
    970 A.2d 640
     (2009).
    After initiating the direct action, the plaintiff then carries the burden,
    under § 22a-17, of making a prima facie showing that the defendant’s actions
    will have an unreasonable environmental impact. Only after the plaintiff
    makes a prima facie case does the burden shift to the defendants to produce
    evidence demonstrating that either the challenged action will not have an
    adverse environmental impact or that there are no feasible and prudent
    alternatives to the defendant’s conduct. See Waterbury v. Washington,
    
    supra,
     
    260 Conn. 550
    –51.
    It is axiomatic that ‘‘the legislature is always presumed to have created
    a harmonious and consistent body of law . . . .’’ (Internal quotation marks
    omitted.) Board of Education v. State Board of Education, 
    278 Conn. 326
    ,
    333, 
    898 A.2d 170
     (2006). It follows, therefore, that an intervening plaintiff
    under § 22a-19 (a) would similarly be required under § 22a-19 (b) to produce
    some evidence that the challenged action is reasonably likely to result in
    unreasonable environmental impact before the department is required to
    consider feasible and prudent alternatives.
    32
    We note that the procedural posture in both Paige and Evans also
    supports our conclusion that triggering the agency’s consideration of feasible
    alternatives under § 22a-19 (b) requires more than successfully alleging
    intervenor standing under § 22a-19 (a). Indeed, there was no question that
    the plaintiffs in Paige and Evans had successfully joined the administrative
    proceedings pursuant to § 22a-19 (a). Had intervention in the proceedings
    been the only requirement necessary to trigger the agency’s consideration
    of feasible alternatives under § 22a-19 (b), as the plaintiff suggests, our
    Supreme Court, and subsequently this court, would not have determined
    that a preliminary finding of unreasonable environmental impairment was
    necessary to trigger review of potentially feasible alternatives.
    33
    The plaintiff argues, in the alternative, that she successfully met her
    burden of production required under § 22a-19. Specifically, the plaintiff con-
    tends that, ‘‘[i]n General Statutes § 22a-91, the General Assembly made
    legislative findings that the waters of Long Island Sound and its coastal
    resources, including tidal wetlands, are assets of great present and potential
    value to the economic well-being of the state, and that there is a state interest
    in the effective management, beneficial use, protection and development of
    these coastal resources. By virtue of these legislative findings, the simple
    fact that the structures are constructed entirely within tidal wetlands is
    sufficient, in and of itself, to satisfy the requirement of § 22a-19 of impairment
    or destruction of natural resources. All that remains is a showing that the
    impairment or destruction is unreasonable.’’ (Footnote omitted.)
    As we have explained previously in this opinion, an agency’s consideration
    of feasible alternatives under § 22a-19 (b) requires a preliminary finding that
    the defendant’s proposed action is likely, or is reasonably likely, to cause
    unreasonable environmental impairment. Accordingly, the plaintiff’s argu-
    ment, which concedes that the legislative finding, without more, does not
    demonstrate unreasonable impairment cannot trigger the department’s con-
    sideration of feasible alternatives under § 22a-19 (b). Moreover, we note
    that the general policy statement set forth in § 22a-91 (5) cannot substitute
    for evidence of unreasonable environmental impairment related to the defen-
    dants’ individual dock application. We conclude, therefore, that the plaintiff’s
    argument must fail.
    34
    The plaintiff also contends that the trial court’s determination and, by
    extension, the proposed and final decisions, are ‘‘contrary to [the depart-
    ment’s] guidelines,’’ which encourage ‘‘[t]he sharing of docks by adjacent
    waterfront property owners.’’ In particular, the plaintiff cites General Stat-
    utes § 22a-92 (b) (1) (H) (ii) to argue that the defendants were required to
    ‘‘utilize existing altered, developed or redevelopment areas,’’ namely, the
    community dock located a short distance away from the proposed structure.
    This court, however, previously has rejected the argument that the exis-
    tence of a community dock limits the applicant’s right to wharf and construct
    such a structure on his or her property. See Lawrence v. Dept. of Energy &
    Environmental Protection, 
    supra,
     
    178 Conn. App. 643
    –44 (‘‘Whether [the
    applicant] should appropriately forgo its right to wharf because of the [com-
    munity] facility is not the question—the existence of the community facility
    does not automatically preclude the right of [the applicant] to construct its
    pier. Rather, the issue is whether the [department] analyzed this application
    to construct a pier under the substantial evidence standard in light of our
    relevant environmental statutes, regulations, and other appropriate factors.
    . . . The [department] noted the salutary purpose of [§ 22a-92 (b) (1)] to
    utilize existing altered, developed or redevelopment areas, where feasible,
    is aimed at encouraging the smart development of coastal areas particularly
    facilities like marinas or state boat launches that are not necessarily limited
    to one particular upland parcel. . . . Yet, this goal must be balanced with
    the littoral owner’s right to wharf and is subject to reasonable regulation.’’
    (Citation omitted; internal quotation marks omitted.)) We conclude, accord-
    ingly, that the plaintiff’s argument is without merit.
