    GEORGE W. NORTHRUP ET AL. v. HENRY J.
    WITKOWSKI, JR., ET AL.
    (SC 20023)
    Robinson, C. J., and Palmer, McDonald,
    D’Auria, Kahn and Ecker, Js.
    Syllabus
    Pursuant to statute (§ 52-557n [a] [2] [B]) and the common law of this
    state, respectively, municipalities and their employees enjoy qualified
    immunity from liability for their negligent acts or omissions in the perfor-
    mance of duties that require the exercise of judgment or discretion.
    The plaintiffs, who reside in the borough of Naugatuck on a particular parcel
    of property that is prone to flooding, appealed to the Appellate Court
    from the trial court’s judgment in favor of the defendants, the borough
    and several of its officials, which was rendered on the basis of govern-
    mental immunity. The plaintiffs had alleged, inter alia, that the defen-
    dants’ negligence caused their property to be inundated by water on
    eight separate occasions. Specifically, the plaintiffs had alleged that a
    nearby municipally owned catch basin in the area routinely became
    clogged or otherwise inadequately redirected storm water away from
    their property. In support of their motion for summary judgment, the
    defendants claimed that the plaintiffs’ negligence claims were barred
    by governmental immunity because they involved acts or omissions that
    required the exercise of judgment or discretion. In granting that motion,
    the trial court concluded that, because the municipal ordinance setting
    forth the general duties of the relevant municipal department did not
    contain specific directions or mandates as to how those duties should
    be discharged, the plaintiffs’ claims necessarily pertained to discretion-
    ary acts or omissions. The trial court acknowledged this court’s decision
    in Spitzer v. Waterbury (
    113 Conn. 84
    ), which held that the repair and
    maintenance of municipally owned drainage systems are ministerial
    functions, but concluded that, under more recent case law, the duty to
    repair and maintain drainage systems is discretionary unless an ordi-
    nance prescribes the particular manner in which that duty is to be
    discharged. The plaintiff subsequently appealed from the trial court’s
    judgment in favor of the defendants to the Appellate Court, which distin-
    guished the facts of Spitzer and ultimately agreed that there was no
    genuine issue of material fact with respect to whether the allegedly
    negligent omissions in the present case were discretionary in nature.
    Accordingly, the Appellate Court affirmed the trial court’s judgment,
    and the plaintiffs, on the granting of certification, appealed to this court.
    Held that the Appellate Court properly upheld the trial court’s granting
    of summary judgment in favor of the defendants, this court having
    concluded that the borough’s duty to maintain and repair its drainage
    system was discretionary rather than ministerial in nature and, therefore,
    subject to governmental immunity: neither the question of whether the
    duty to repair and maintain the drainage system was imposed by statute
    or voluntarily assumed, nor the distinction between construction and
    repair, was relevant to consideration of the nature of the defendants’
    duty, because, under modern principles of governmental immunity, the
    salient consideration in determining whether that duty was discretionary
    or ministerial is whether any statute, charter provision, ordinance, regu-
    lation, rule, policy, or any other directive required the defendants to act
    in a prescribed manner, and, accordingly, the defendants could be held
    liable to the plaintiffs only if there was some legal directive prescribing
    the specific manner in which the defendants were required to maintain
    and repair the borough’s storm drainage system; moreover, the plaintiffs
    did not challenge the Appellate Court’s conclusion that the language
    of the relevant municipal ordinance did not, in and of itself, create a
    ministerial duty to repair and maintain the drainage system, and, even
    if this court were to assume that a policy or rule from a municipal
    agency could give rise to a ministerial duty, deposition testimony from
    the borough’s superintendent of streets evincing an annual maintenance
    schedule and a general policy of attempting to respond to public com-
    plaints about clogged storm drains was insufficient to establish the
    existence of such a policy or rule that could convert the borough’s
    discretionary duty mandated by ordinance into a ministerial duty, as a
    contrary conclusion would disincentivize municipalities from making
    virtually any attempt to ensure that their discretionary duties are regu-
    larly and properly carried out; furthermore, this court could not conclude
    that the defendants had breached a ministerial duty by failing to conduct
    any maintenance on the basin at issue because the plaintiffs cited no
    evidence that would support such a finding, and, even if they had, a
    general duty to maintain and repair the drainage system as a whole
    would not encompass a judicially enforceable duty to maintain and
    repair each individual component of that system.
    Spitzer v. Waterbury (
    113 Conn. 84
    ), to the extent it concluded that munici-
    pal duties with respect to the maintenance and repair of drains and
    sewers are ministerial in nature, overruled.

    Procedural History
    Action to recover damages for the alleged negligence
    of the named defendant et al. in maintaining and
    repairing certain municipal storm water systems, and
    for other relief, brought to the Superior Court in the
    judicial district of New Haven, where the court, Blue,
    J., granted the defendants’ motion for summary judg-
    ment and rendered judgment thereon, from which the
    plaintiffs appealed to the Appellate Court, Alvord, Pres-
    cott and Mullins, Js., which affirmed the trial court’s
    judgment, and the plaintiffs, on the granting of certifica-
    tion, appealed to this court. Affirmed.
    Joshua F. Gilman, for the appellants (plaintiffs).
    Thomas R. Gerarde, with whom, on the brief, was
    Beatrice S. Jordan, for the appellees (defendants).
    Aaron S. Bayer and Tadhg Dooley filed a brief for
    the city of Bridgeport et al. as amici curiae.
    Opinion
    ROBINSON, C. J. This certified appeal requires us to
    consider the continued vitality of this court’s decision
    in Spitzer v. Waterbury, 
    113 Conn. 84
    , 88, 
    154 A. 157
    (1931), which held that ‘‘[t]he work of constructing
    drains and sewers, as well as that of keeping them in
    repair, is ministerial, and the municipality is respon-
    sible for negligence in its performance.’’ The plaintiffs,
    Helen M. Northrup, George W. Northrup, and Timothy
    Northrup,1 brought this action against the defendants,
    the borough of Naugatuck (town) and several town offi-
    cials,2 claiming, inter alia, that the defendants’ negli-
    gence in maintaining and repairing the town’s storm
    drains and drainage pipes had caused the repeated
    flooding of the plaintiffs’ residence. The plaintiffs now
    appeal, upon our granting of their petition for certifica-
    tion,3 from the judgment of the Appellate Court affirm-
    ing the trial court’s granting of the defendant’s motion
    for summary judgment on the ground that the negli-
    gence claims were barred because, under more recent
    cases refining and clarifying Spitzer, the maintenance
    of storm drains and drainage systems is a discretionary
    function subject to governmental immunity, rather than
    a ministerial function, the negligent performance of
    which can subject a municipality to liability. Northrup
    v. Witkowski, 
    175 Conn. App. 223
    , 250, 
    167 A.3d 443
    (2017). We disagree with the plaintiffs’ claim that the
    Appellate Court improperly failed to follow Spitzer
    because we conclude that decision must be overruled
    in light of modern case law governing the distinction
    between ministerial and discretionary duties. Accord-
    ingly, we affirm the judgment of the Appellate Court.
    The opinion of the Appellate Court aptly sets forth the
    following facts and procedural history. ‘‘The plaintiffs
    reside on property located in the town at 61 Nettleton
    Avenue. On eight different occasions between 2009 and
    2012, the plaintiff’s property was damaged when surface
    rainwater and/or ‘black water’4 inundated the property
    because the single catch basins in the area routinely
    became clogged or inadequately redirected water away
    from the property.
    ‘‘After the first occurrence in July, 2009, Helen . . .
    contacted [James] Stewart, who, at that time, was
    the [town] engineer. He told her that the flooding was
    the result of a rare storm and that it would not hap-
    pen again. Despite his assurance, however, flooding
    occurred again in October and December of that year.
    The plaintiffs continued to contact Stewart, to no avail.
    The plaintiffs made several requests to the town for
    sandbags; one such request was granted, but others
    were denied or simply ignored.
    ‘‘The town received a report in October, 2009, from
    an engineering firm about the Nettleton Avenue neigh-
    borhood. The report indicated that, over the past forty
    years, many residences in the neighborhood had experi-
    enced periodic flooding of their properties following
    periods of heavy rainfall. It further indicated that the
    drainage system in the area was likely to experience
    flooding after rainfalls of two inches or more, which
    could occur several times a year. The report attributed
    the flooding to the fact that runoff was required to flow
    through relatively narrow drainpipes that were in poor
    to fair condition and that the majority of catch basins
    in the area were old and had small openings that often
    became overgrown with vegetation or obstructed by
    trash. The report recommended that the town construct
    new, larger storm drains to handle the storm runoff in
    the area, but the town failed to adopt that proposal.
    The plaintiffs’ property flooded again in July of 2010,
    March and August of 2011, and June and September of
    2012.’’ (Footnote in original.) 
    Id., 226–27. On
    June 4, 2013, the plaintiffs filed the operative
    second amended complaint alleging negligence against
    Henry J. Witkowski, Stewart, and the town, and reck-
    lessness against the individual defendants. See footnote
    2 of this opinion. In addition, the plaintiffs alleged negli-
    gent infliction of emotional distress against Witkowski,
    Stewart, and the town.
    ‘‘On October 30, 2015, the defendants filed [a] motion
    for summary judgment . . . . The defendants submit-
    ted a supporting memorandum of law, attached to
    which were partial transcripts from the depositions of
    Helen . . . and the individual defendants, as well as
    an affidavit by Stewart. The defendants argued that
    the negligence counts, including those alleging negli-
    gent infliction of emotional distress, were barred by
    governmental immunity because they involved acts or
    omissions that required the exercise of judgment or
    discretion, and no other recognized exception to gov-
    ernmental immunity applied. The defendants further
    argued that the recklessness counts brought against the
    individual defendants also failed as a matter of law
    because, on the basis of the allegations and evidence
    presented, no reasonable fact finder could determine
    that the individual defendants had engaged in demon-
    strably reckless conduct.
    ‘‘The plaintiffs filed an objection to the motion for
    summary judgment on November 18, 2015, arguing with
    respect to the negligence counts that there remained
    genuine issues of material fact as to whether the defen-
    dants were exercising ministerial or discretionary
    duties and, if discretionary, whether the identifiable
    person-imminent harm exception to governmental
    immunity applied.’’ Northrup v. 
    Witkowski, supra
    , 
    175 Conn. App. 228
    –29.
    ‘‘On January 20, 2016, the court issued a memoran-
    dum of decision granting summary judgment in favor
    of the defendants on all counts. With respect to the
    negligence counts, including those counts alleging neg-
    ligent infliction of emotional distress, the court con-
    cluded that the plaintiffs’ specifications of negligence
    amounted to a ‘litany of discretionary omissions’ and
    that their ‘allegations boiled down to a claim that the
    defendants failed to perform their municipal duties in
    an appropriate manner.’ The court determined that the
    city ordinance on which the plaintiffs relied in opposing
    summary judgment only set forth the general duties of
    the [streets commission] without any specific directions
    or mandates as to how those duties should be dis-
    charged.’’ 
    Id., 230. The
    trial court acknowledged this court’s decision in
    Spitzer v. 
    Waterbury, supra
    , 
    113 Conn. 88
    , holding that
    the repair and maintenance of drainage systems is a
    ministerial function, but concluded that more recent
    cases had ‘‘refined [the] analysis of the relationship and
    differences between ministerial and discretionary acts
    . . . .’’ Silberstein v. 54 Hillcrest Park Associates, LLC,
    
    135 Conn. App. 262
    , 272, 
    41 A.3d 1147
    (2012). The trial
    court concluded that, under those more recent cases,
    the repair and maintenance of drainage systems are
    discretionary unless an ordinance ‘‘prescribe[s] the
    manner in which the drainage systems are to be main-
    tained . . . .’’ (Emphasis in original.)
    ‘‘Accordingly, the court concluded that the defen-
    dants’ acts or omissions in maintaining the town’s drain-
    age system were discretionary in nature. Furthermore,
    the court concluded that the identifiable person-immi-
    nent harm exception to discretionary act immunity was
    inapplicable as a matter of law because the risk of the
    property flooding at any given time was indefinite and,
    thus, did not constitute an imminent harm. The court
    also granted summary judgment with respect to the
    recklessness counts, concluding that they also were
    barred by governmental immunity.
    ‘‘The plaintiffs filed a motion to reargue and for recon-
    sideration, which the defendants opposed. The court
    denied the plaintiffs’ motion, and [the plaintiffs’ appeal
    to the Appellate Court] followed.’’5 Northrup v. Witkow-
    
    ski, supra
    , 
    175 Conn. App. 230
    .
    The Appellate Court held that ‘‘to demonstrate the
    existence of a ministerial duty on the part of a munici-
    pality and its agents, a plaintiff ordinarily must point
    to some statute, city charter provision, ordinance, regu-
    lation, rule, policy, or other directive that, by its clear
    language, compels a municipal employee to act in a
    prescribed manner, without the exercise of judgment
    or discretion. See Violano v. Fernandez, 
    280 Conn. 310
    ,
    323, 
    907 A.2d 1188
    (2006); Evon v. Andrews, 
    211 Conn. 501
    , 506–507, 
    559 A.2d 1131
    (1989); DiMiceli v. Chesh-
    ire, [
    162 Conn. App. 216
    , 224–25, 
    131 A.3d 771
    (2016)];
    Grignano v. Milford, 
    106 Conn. App. 648
    , 659–60, 
    943 A.2d 507
    (2008).’’ Northrup v. 
    Witkowski, supra
    , 
    175 Conn. App. 235
    . The court ultimately concluded that,
    ‘‘although there is language in § 16-32 of the [Naugatuck
    Code of Ordinances] that requires the streets commis-
    sion to maintain and repair the town’s storm water
    sewer system, the ordinance contains no provisions
    that mandate the time or manner in which those respon-
    sibilities are to be executed, leaving such details to the
    discretion and judgment of the municipal employees.’’
    
    Id., 238. The
    Appellate Court then acknowledged this court’s
    statement in Spitzer v. 
    Waterbury, supra
    , 
    113 Conn. 88
    ,
    that the repair and maintenance of drains and sewers
    are ministerial functions, but it concluded that Spitzer
    was distinguishable on its facts because it involved only
    the question of whether a drainage system ‘‘as it was
    planned could handle even ordinary amounts of rain,’’
    not whether the city had properly maintained and
    cleaned the system. Northrup v. 
    Witkowski, supra
    , 
    175 Conn. App. 239
    . In addition, the Appellate Court con-
    cluded that the statement in Spitzer was dictum. 
    Id., 241. The
    Appellate Court concluded that, ‘‘[c]onsidered
    in light of our modern case law analyzing qualified gov-
    ernmental immunity, we are convinced that the [trial]
    court correctly determined that there was no genuine
    issue of material fact to be resolved with respect to
    whether the alleged[ly] negligent acts or omissions of
    the defendants were discretionary in nature and, thus,
    subject to immunity.’’ 
    Id., 242. Accordingly,
    the Appel-
    late Court affirmed the judgment of the trial court. 
    Id., 250. This
    certified appeal followed.6 See footnote 3 of
    this opinion.
    On appeal to this court, the plaintiffs contend that
    the Appellate Court incorrectly determined both that
    Spitzer is distinguishable on its facts and that this
    court’s statement in Spitzer that the repair and mainte-
    nance of drains and sewers are ministerial functions
    was dictum. Rather, they argue that Spitzer is directly
    on point and is binding authority for the proposition
    that the duty of a municipality to maintain and repair
    its drainage system is ministerial and, therefore, that
    the negligent performance of that duty will subject the
    municipality to liability. We conclude that we need not
    determine whether the language in Spitzer was dictum
    because, even if it was not, Spitzer must be overruled
    in light of more modern case law and statutes governing
    the distinction between ministerial and discretionary
    duties. We further conclude that the Appellate Court
    correctly determined that, under those more modern
    cases, the town’s duty to maintain and repair its drain-
    age system was discretionary and, therefore, subject to
    governmental immunity.
    As a preliminary matter, we set forth the standard
    of review. ‘‘Summary judgment shall be rendered forth-
    with if the pleadings, affidavits and other proof submit-
    ted show that there is no genuine issue as to any
    material fact and that the moving party is entitled to
    judgment as a matter of law. . . . The scope of our
    appellate review depends upon the proper characteriza-
    tion of the rulings made by the trial court. . . . When
    . . . the trial court draws conclusions of law, our
    review is plenary and we must decide whether its con-
    clusions are legally and logically correct and find sup-
    port in the facts that appear in the record.’’ (Internal
    quotation marks omitted.) Meyers v. Livingston, Adler,
    Pulda, Meiklejohn & Kelly, P.C., 
    311 Conn. 282
    , 289–90,
    
    87 A.3d 534
    (2014).
    We next review the law governing governmental
    immunity. ‘‘The [common-law] doctrines that determine
    the tort liability of municipal employees are well estab-
    lished. . . . Generally, a municipal employee is liable
    for the misperformance of ministerial acts, but has a
    qualified immunity in the performance of governmental
    acts. . . . Governmental acts are performed wholly for
    the direct benefit of the public and are supervisory or
    discretionary in nature. . . . The hallmark of a discre-
    tionary act is that it requires the exercise of judgment.
    . . . In contrast, [m]inisterial refers to a duty which is
    to be performed in a prescribed manner without the
    exercise of judgment or discretion.’’ (Internal quotation
    marks omitted.) Violano v. 
    Fernandez, supra
    , 
    280 Conn. 318
    .
    ‘‘The tort liability of a municipality has been codified
    in [General Statutes] § 52-557n. Section 52-557n (a) (1)
    provides that ‘[e]xcept as otherwise provided by law,
    a political subdivision of the state shall be liable for
    damages to person or property caused by: (A) The negli-
    gent acts or omissions of such political subdivision or
    any employee, officer or agent thereof acting within
    the scope of his employment or official duties . . . .’
    Section 52-557n (a) (2) (B) extends, however, the same
    discretionary act immunity that applies to municipal
    officials to the municipalities themselves by providing
    that they will not be liable for damages caused by ‘negli-
    gent acts or omissions which require the exercise of
    judgment or discretion as an official function of the
    authority expressly or impliedly granted by law.’ ’’
    
    Id., 320. ‘‘Municipal
    officials are immunized from liability for
    negligence arising out of their discretionary acts in part
    because of the danger that a more expansive exposure
    to liability would cramp the exercise of official discre-
    tion beyond the limits desirable in our society. . . .
    Discretionary act immunity reflects a value judgment
    that—despite injury to a member of the public—the
    broader interest in having government officers and
    employees free to exercise judgment and discretion in
    their official functions, unhampered by fear of second-
    guessing and retaliatory lawsuits, outweighs the bene-
    fits to be had from imposing liability for that injury.
    . . . In contrast, municipal officers are not immune
    from liability for negligence arising out of their ministe-
    rial acts, defined as acts to be performed in a prescribed
    manner without the exercise of judgment or discretion.
    . . . This is because society has no analogous interest
    in permitting municipal officers to exercise judgment
    in the performance of ministerial acts.’’ (Internal quota-
    tion marks omitted.) 
    Id., 318–19. ‘‘This
    court has identified two other policy rationales
    for immunizing municipalities and their officials from
    tort liability. The first rationale is grounded in the princi-
    ple that for courts to second-guess municipal policy
    making by imposing tort liability would be to take the
    administration of municipal affairs out of the hands to
    which it has been entrusted by law. . . . Second, we
    have recognized that a civil trial may be an inappropri-
    ate forum for testing the wisdom of legislative actions.
    This is particularly true if there is no readily ascertain-
    able standard by which the action of the government
    servant may be measured . . . . Thus, [t]he policy
    behind the exception is to avoid allowing tort actions
    to be used as a monkey wrench in the machinery of
    government decision making.’’ (Citation omitted; inter-
    nal quotation marks omitted.) 
    Id., 319 n.7.
        For purposes of determining whether a duty is discre-
    tionary or ministerial, this court has recognized that
    ‘‘[t]here is a difference between laws that impose gen-
    eral duties on officials and those that mandate a particu-
    lar response to specific conditions.’’ Bonington v.
    Westport, 
    297 Conn. 297
    , 308, 
    999 A.2d 700
    (2010). ‘‘A
    ministerial act is one which a person performs in a given
    state of facts, in a prescribed manner, in obedience to
    the mandate of legal authority, without regard to or the
    exercise of his own judgment [or discretion] upon the
    propriety of the act being done.’’7 (Internal quotation
    marks omitted.) Blake v. Mason, 
    82 Conn. 324
    , 327, 
    73 A. 782
    (1909); see also Benedict v. Norfolk, 
    296 Conn. 518
    , 520 n.4, 
    997 A.2d 449
    (2010) (municipal acts are
    ‘‘deemed ministerial if a policy or rule limiting discre-
    tion in the completion of such acts exists’’); Pluhowsky
    v. New Haven, 
    151 Conn. 337
    , 347, 
    197 A.2d 645
    (1964)
    (describing ministerial acts in similar terms). In con-
    trast, when an official has a general duty to perform
    a certain act, but there is no ‘‘city charter provision,
    ordinance, regulation, rule, policy, or any other direc-
    tive [requiring the government official to act in a] pre-
    scribed manner,’’ the duty is deemed discretionary.
    Violano v. 
    Fernandez, supra
    , 
    280 Conn. 323
    .
    ‘‘In general, the exercise of duties involving inspec-
    tion, maintenance and repair of hazards are considered
    discretionary acts entitled to governmental immunity.’’
    Grignano v. 
    Milford, supra
    , 
    106 Conn. App. 656
    . This
    is so because there ordinarily is no legal directive man-
    dating the specific manner in which officials must per-
    form these tasks. Rather, ‘‘[a] municipality necessarily
    makes discretionary policy decisions with respect to the
    timing, frequency, method and extent of inspections,
    maintenance and repairs.’’ Id.; see also Bonington v.
    
    Westport, supra
    , 
    297 Conn. 308

    ates, 
    LLC, supra
    , 
    135 Conn. App. 273
    , that the mainte-
    nance of storm drains is discretionary in nature. See
    also Brusby v. Metropolitan District,

    (2015) (in absence of legal direc-
    tive prescribing manner in which sanitary sewer system
    was to be maintained or repaired, duty was discretion-

    Hillcrest Park neighborhood of Old Greenwich. Silb-
    erstein v. 54 Hillcrest Park Associates, 
    LLC, supra
    , 264.
    The plaintiffs alleged that the defendants, the Hillcrest
    Park Tax District (tax district) and Hillcrest Park Asso-
    ciation, Inc., which were responsible for maintaining
    and constructing roads and storm sewers in the Hill-
    crest neighborhood, had negligently failed to do so,
    resulting in the periodic flooding of the plaintiffs’ prop-
    erty. 
    Id., 264–65. The
    trial court granted the defendant’s
    motion for summary judgment on the ground of govern-
    mental immunity. 
    Id., 267. On
    appeal, the Appellate
    Court noted that, although the tax district’s bylaws
    stated clearly that one of the functions of that organiza-
    tion was ‘‘to construct and maintain roads . . . drains,
    [and] storm sewers’’; (internal quotation marks omit-
    ted) 
    id., 273; the
    bylaws did not ‘‘prescribe the manner
    in which the roads and drainage systems [were] to be
    maintained, and there [was] no evidence in the record
    of any procedure or directive governing the manner of
    their maintenance.’’ (Emphasis in original.) 
    Id. Accord- ingly,
    the court concluded that ‘‘the manner in which
    the defendants discharge their duty to maintain the
    roads and drainage systems plainly involves the exer-
    cise of judgment and discretion,’’ and the duty was,
    therefore, discretionary. 
    Id. Like the
    plaintiffs in the present case, the plaintiffs
    in Silberstein had relied on this court’s statement in
    Spitzer v. 
    Waterbury, supra
    , 
    113 Conn. 88
    , that ‘‘[t]he
    work of constructing drains and sewers, as well as
    that of keeping them in repair, is ministerial, and the
    municipality is responsible for negligence in its perfor-
    mance’’ to support their contention to the contrary.
    Silberstein v. 54 Hillcrest Park Associates, 
    LLC, supra
    ,
    
    135 Conn. App. 272
    . In Silberstein, the Appellate Court
    concluded that Spitzer was distinguishable on the
    ground that this court had concluded in Spitzer that
    ‘‘a municipality’s construction and repair of storm water
    sewers and drains [were] ministerial because [they
    were] ‘incidental to’ the municipality’s statutorily
    imposed duty to maintain its streets and highways. . . .
    The court [in Spitzer] reasoned: ‘The duty imposed by
    statute upon the municipality to maintain the highways
    within its limits makes it necessary for the municipality
    to dispose of all surface water falling upon them.’ . . .
    Thus, the municipality was legally obligated to maintain
    and repair the drains. In contrast to the municipality
    in Spitzer, the defendants in [Silberstein were] not
    charged with having failed to fulfill a duty that was
    imposed upon them by statute. Rather, the plaintiffs
    claim[ed] that the defendants negligently failed to carry
    out a duty that they assumed pursuant to the tax district
    bylaws. The tax district bylaws, however, [did] not pre-
    scribe the specific manner in which the duty to maintain
    and repair the roads, drains and storm sewers is to be
    performed.’’ (Citations omitted; emphasis in original.)
    
    Id., 272, quoting
    Spitzer v. 
    Waterbury, supra
    , 87–88.
    The plaintiffs in the present case contend that Spitzer
    is controlling because, as in that case—unlike Silb-
    erstein—the duty of the defendants to repair and main-
    tain the drainage system ‘‘originate[s] from the General
    Statutes, which require Connecticut municipalities to
    maintain the highways within their limits.’’8 The plain-
    tiffs further contend that Silberstein is distinguishable
    because the plaintiffs in that case alleged that the defen-
    dants had negligently failed to install a properly func-
    tioning drainage system, and ‘‘the decision to build or
    construct storm water systems is almost universally
    held to be a governmental discretionary act.’’ (Emphasis
    added.) In contrast, the plaintiffs in the present case
    allege that the defendants failed to adequately main-
    tain and repair the storm drainage system, which, they
    argue are ministerial duties. We disagree with both of
    these claims.
    We first address the plaintiffs’ contention that the
    defendants’ duty to maintain and repair the sewer sys-
    tem is ministerial because it derives from statute rather
    from the town’s own ordinances or rules. As we have
    indicated, the Appellate Court also made this distinction
    in Silberstein v. 54 Hillcrest Park Associates, 
    LLC, supra
    , 
    135 Conn. App. 272
    . In support of the proposition
    that a duty imposed on a municipality by statute is
    necessarily ministerial, whereas a duty voluntarily
    assumed by the municipality is discretionary, the Appel-
    late Court cited only this court’s statement in Spitzer
    v. 
    Waterbury, supra
    , 
    113 Conn. 87
    , that ‘‘[t]he duty
    imposed by statute upon the municipality to maintain
    the highways within its limits makes it necessary for
    the municipality to dispose of all surface water falling
    upon them.’’ (Internal quotation marks omitted.) Silb-
    erstein v. 54 Hillcrest Park Associates, 
    LLC, supra
    , 272.
    In turn, Spitzer v. 
    Waterbury, supra
    , 87, supported that
    proposition with a citation to Bronson v. Wallingford,
    
    54 Conn. 513
    , 519–20, 
    9 A. 393
    (1887), in which this
    court suggested, in dictum and without citation to any
    authority, that a municipality may be held liable for
    damages caused while carrying out its statutory duty
    to dispose of surface waters falling on its highways,
    whereas it would be immune from liability for acts
    performed pursuant to a duty imposed by the city char-
    ter in the absence of any charter provision providing
    a remedy.9
    Other cases predating Spitzer present a mirror image
    of this proposition, however, and hold that municipali-
    ties may not be held liable when they violate public
    duties that have been imposed on them by the state,
    whereas municipalities can be held liable for the viola-
    tion of duties that they voluntarily take upon them-
    selves. In Jones v. New Haven, 
    34 Conn. 1
    , 13 (1867), this
    court stated that ‘‘[w]henever a public duty is imposed
    upon a town . . . without its consent, express or
    implied, such town . . . is not liable to an action for
    negligence in respect to such duty, unless a right of
    action is given by statute.’’ (Emphasis added.) In con-
    trast, ‘‘when a grant is made to a [municipality] of some
    special power or privilege at its request, out of which
    public duties grow; and when some special duty is
    imposed upon a [municipality] not belonging to it under
    the general law with its consent; in these and like cases,
    if the corporation is guilty of negligence in the discharge
    of such duty, thereby causing injury to another, it is
    liable to an action in favor of the party injured.’’ (Empha-
    sis added.) 
    Id., 14; see
    also Dyer v. Danbury, 
    85 Conn. 128
    , 131, 
    81 A. 958
    (1911) (same). There are also cases
    predating Spitzer holding that acts performed pursuant
    to voluntarily assumed duties may be governmental
    and, therefore, immune from liability, as well as acts
    performed pursuant to duties imposed by statute. See
    Hannon v. Waterbury, 
    106 Conn. 13
    , 17, 
    126 A. 876
    (1927) (‘‘Whether the duty is directly imposed upon
    the city or permissive, that is, one which it voluntarily
    assumed . . . does not change the character of the act
    or function. The duty in either case will be governmental
    if the nature and character of [the] act or function be
    such.’’); Pope v. New Haven, 
    91 Conn. 79
    , 82, 
    99 A. 51
    (1916) (function may be governmental regardless of
    whether ‘‘the legislature determines the necessity and
    expediency of the act to be performed’’ or ‘‘the necessity
    and expediency are left to be determined by the munici-
    pality’’). We are aware of no authority other than the
    court’s unsupported dictum in Bronson v. 
    Wallingford, supra
    , 
    54 Conn. 519
    –20, however, that would support
    Spitzer’s suggestion that a duty imposed by statute, as
    distinct from a duty that is voluntarily assumed by the
    municipality, is by virtue of that fact ministerial.
    In any event, the distinction applied by the court in
    Jones and Dyer has been superseded by more recent
    developments in municipal law and the law governing
    governmental immunity. As the Appellate Court recog-
    nized in Roman v. Stamford, 
    16 Conn. App. 213
    , 219,
    
    547 A.2d 97
    (1988), aff’d, 
    211 Conn. 396
    , 
    559 A.2d 710
    (1989), ‘‘[u]nlike the Dyer and Jones doctrine of
    assumption of municipal liability based upon a charter
    provision, the modern construct of municipal liability
    rests upon distinctly different considerations.’’ See also
    
    id., 218–19 (‘‘construct
    [set forth in Jones and Dyer],
    wherein special powers are granted to or imposed upon
    the municipality, harkens back to the days before the
    advent of the principle of home rule’’ and, therefore, is
    no longer ‘‘a valid conceptualization of the doctrine of
    actionable private duties of a municipality’’).10 Specifi-
    cally, under modern principles of governmental immu-
    nity, the salient consideration in determining whether
    a municipal duty is discretionary or ministerial is not
    whether the duty was imposed on the municipality by
    statute or voluntarily assumed pursuant to its own ordi-
    nances or regulations, but whether there is any statute,
    ‘‘city charter provision, ordinance, regulation, rule, pol-
    icy, or any other directive [requiring the government
    official to act in a] prescribed manner.’’ (Emphasis
    added.) Violano v. 
    Fernandez, supra
    , 
    280 Conn. 323
    ;
    see also Roman v. 
    Stamford, supra
    , 221 (under modern
    principles of governmental immunity, ‘‘[a] ministerial
    act, as opposed to a discretionary act, refers to [one]
    which is to be performed in a prescribed manner with-
    out the exercise of judgment or discretion’’ [internal
    quotation marks omitted]). Accordingly, we disagree
    with the plaintiffs’ argument that Silberstein v. 54 Hill-
    crest Park Associates, 
    LLC, supra
    , 
    135 Conn. App. 272
    ,
    is not controlling because, unlike in Silberstein, the
    defendants’ duty in the present case was imposed by
    statute.
    We next address the plaintiffs’ argument that, in con-
    trast to the design of storm water drainage systems,
    the duty to repair and maintain such systems is ministe-
    rial. In support of this claim, the plaintiffs rely on several
    cases from other jurisdictions. The holdings of those
    cases, however, can be traced to the outmoded distinc-
    tion between duties that are imposed on municipalities
    and those that they voluntarily assume. See Johnston
    v. District of Columbia, 
    118 U.S. 19
    , 21, 
    6 S. Ct. 923
    , 
    30 L. Ed. 75
    (1886) (repair of sanitary sewer is ministerial
    duty), citing Child v. Boston, 
    86 Mass. 41
    , 52 (1862)
    (municipality is not liable for defective sanitary sewer
    plan because creation of plan involved duty of quasi-
    judicial nature, but could be held liable for negligent
    care and maintenance of sanitary sewers because those
    duties were not imposed by legislative authority for
    public purposes but were voluntarily assumed by
    municipality); Barton v. Syracuse, 
    36 N.Y. 54
    , 54 (1867)
    (municipality was liable for negligent failure to repair
    sanitary sewers because it voluntarily accepted duty
    and assessed costs on beneficiaries);11 Portsmouth v.
    Mitchell Mfg. Co., 
    113 Ohio St. 250
    , 255–56, 
    148 N.E. 846
    (1925) (citing Barton and concluding that municipality
    cannot be held liable for failure to construct storm
    sewer but can be held liable for failure to keep storm
    sewer in repair). In addition, all of these cases either
    involved or relied on cases involving the maintenance
    and repair of sanitary sewers, which, unlike the mainte-
    nance and repair of storm sewers, arguably may be a
    proprietary function under certain circumstances, even
    under more modern case law.12 See footnote 10 of
    this opinion.
    We recognize that, for purposes of imposing liability
    on a municipality, some Connecticut cases predating
    Spitzer made the distinction between a municipality’s
    duty to construct roads and sidewalks, and, by exten-
    sion, the storm drains and sewers that are required to
    ensure that the roads are functional, as opposed to a
    duty of maintenance and repair. In Hoyt v. Danbury,
    
    69 Conn. 341
    , 351, 
    37 A. 1051
    (1897), for example, this
    court observed that a municipality’s statutory obligation
    to provide highways ‘‘carried with it the correlative
    right of determining the mode of their construction,’’
    and ‘‘[a]s to which, out of any appropriate modes of
    building the particular sidewalk in question, was to be
    chosen, it was for the borough to decide; and so long
    as the mode selected was an appropriate and lawful
    one, its decision was not subject to collateral review
    in a suit of this nature.’’ In other words, Hoyt recognized
    that the construction of highways is a discretionary
    function. As to highway repairs, this court noted that
    municipal liability for the failure to keep roads in good
    repair had been imposed by statute, now codified at
    General Statutes § 13a-149,13 ‘‘since early colonial
    times.’’ 
    Id. The highway
    defect statute, however, waives
    governmental immunity from claims by travelers on the
    highway arising from highway defects. See McIntosh
    v. Sullivan, 
    274 Conn. 262
    , 282, 
    875 A.2d 459
    (2005)
    (highway defect statute at issue in Hoyt ‘‘abrogated
    governmental immunity’’). Put differently, the highway
    defect statute does not impose a ministerial duty to
    repair highways, so that a municipality may be held
    liable to abutting landowners for breach of that duty.
    See Aerotec Corp. v. Greenwich, 
    138 Conn. 116
    , 119, 
    82 A.2d 356
    (1951) (highway defect statute ‘‘provides no
    right of recovery to an abutting landowner for damage
    from a defective highway’’). Thus, the distinction made
    in Hoyt between the construction of highways and their
    repair, which was premised on the highway defect stat-
    ute, is consistent with the modern rule distinguishing
    ‘‘laws that impose general duties on officials,’’ which
    impose discretionary duties, ‘‘and those that mandate
    a particular response to specific conditions,’’ which
    impose ministerial duties. Bonington v. 
    Westport, supra
    , 
    297 Conn. 308
    .
    The authority that Spitzer itself cited in support of its
    statement that the duty to construct and repair drainage
    systems is ministerial also can be at least partially rec-
    onciled with the modern rule. In Spitzer, this court
    relied on a treatise on Municipal Corporations authored
    by John F. Dillon. See Spitzer v. 
    Waterbury, supra
    , 
    113 Conn. 88
    , citing 4 J. Dillon, Commentaries on the Law
    of Municipal Corporations (5th Ed. 1911) §§ 1742 and
    1743, pp. 3054–57. That treatise states the following:
    ‘‘[A] municipal corporation is liable for negligence in
    the ministerial duty to keep its sewers . . . in repair
    . . . .’’ (Emphasis in original.) 4 J. Dillon, supra, § 1742,
    p. 3055. A careful review of the treatise, however,
    reveals that this statement was at least partially prem-
    ised on the principle that municipalities are ‘‘bound
    to preserve and keep in repair erections [they have]
    constructed, so that they shall not become a source
    of nuisance to others.’’14 (Emphasis altered; internal
    quotation marks omitted.) 
    Id. Consistent with
    this prin-
    ciple, it is well established in this state that ‘‘towns will
    not be justified in doing an act lawful in itself in such
    a manner as to create a nuisance, any more than individ-
    uals. And if a nuisance is thus created, whereby another
    suffer[s] damage, towns like individuals are responsi-
    ble.’’ (Internal quotation marks omitted.) Hoffman v.

    , 657, 
    54 A.2d 260

    from liability when their employees are acting in dis-
    charge of a public duty does not relieve them from
    liability for the consequences of particular acts which
    the municipality has directed to be performed and
    which, from their character or the manner in which
    they are so ordered to be executed, will naturally work
    a direct injury to others or create a nuisance’’); Colwell
    v. Waterbury, 
    74 Conn. 568
    , 572–73, 
    51 A. 530
    (1902)
    (same); Judd v. Hartford, 
    72 Conn. 350
    , 354, 
    44 A. 510
    (1899) (although duty to construct sewer was govern-
    mental, municipality could be held liable for negligent
    failure to remove temporary obstructions after con-
    struction because failure to do so turned ‘‘city property
    into a nuisance’’); Mootry v. Danbury, 
    45 Conn. 550
    ,
    556 (1878) (when town constructed bridge over stream
    that blocked water flow, causing plaintiff’s upstream
    property to flood, it may be held liable because ‘‘towns
    will not be justified in doing an act lawful in itself
    in such a manner as to create a nuisance, any more
    than individuals’’).15
    The fact that a municipality may be liable for creating
    a nuisance, however, does not necessarily mean—at
    least not under our more recent cases—that the act
    that created the nuisance was ministerial in nature.
    Indeed, this court has held that ‘‘a municipality may be
    liable for a nuisance . . . even if [its] misfeasance or
    nonfeasance also constitutes negligence from which
    the municipality would be immune’’ because the munici-
    pality was engaged in a discretionary function.16 Keeney
    v. Old 
    Saybrook, supra
    , 
    237 Conn. 165
    ; but see Judd
    v. 
    Hartford, supra
    , 
    72 Conn. 353
    –54 (duty to remove
    temporary obstructions from sewer so as to prevent
    creation of nuisance was ministerial).
    In other words, unlike Dillon’s treatise, which seems
    to suggest that ministerial acts are the only acts for
    which a municipality may be held liable and, therefore,
    that if a municipality can be held liable for creating a
    nuisance, the municipal function that resulted in the
    creation of the nuisance must be a ministerial one,
    our more recent cases have treated nuisance and the
    violation of a ministerial duty as entirely distinct theo-
    ries of municipal liability.17 See Grady v. Somers, 
    294 Conn. 324
    , 335 n.10, 
    984 A.2d 684
    (2009) (governmental
    immunity does not apply to claims alleging ‘‘[1] liability
    in nuisance, which [may] be imposed . . . only if the
    condition constituting the nuisance was created by the
    positive act of the municipality; and [2] the negligent
    performance of ministerial acts’’ [internal quotation
    marks omitted]); see also Keeney v. Old 
    Saybrook, supra
    , 
    237 Conn. 165
    . Accordingly, although we agree
    with Dillon’s treatise to the extent that it recognizes
    that there are situations in which a municipality may
    be held liable for damage caused by a storm sewer
    system that the municipality was responsible for main-
    taining and repairing—namely, when the municipality’s
    positive act has created a nuisance—we do not agree
    with its suggested inference from that proposition,
    namely, that the duty to maintain and repair storm sew-
    ers is necessarily ministerial.18 Indeed, if that were the
    case, municipalities could be held liable for any damage
    caused by their failure to maintain and repair storm
    sewer systems, even if the ‘‘positive act’’ element of
    nuisance were not satisfied. See Wright v. 
    Brown, supra
    , 
    167 Conn. 470
    (‘‘[l]iability in nuisance can be
    imposed on a municipality only if the condition consti-
    tuting the nuisance was created by the positive act of
    the municipality’’).
    We therefore disagree with the plaintiffs’ argument
    that, in determining whether a municipality’s duty with
    respect to its storm drains and sewers is ministerial
    or discretionary, the relevant considerations are (1)
    whether the duty was imposed by statute or, instead,
    was voluntarily assumed by the town, and (2) whether
    the municipality was constructing the sewers or,
    instead, was maintaining or repairing them. Rather, the
    relevant consideration under well established modern
    principles of governmental immunity remains whether
    the duty was a general one or, instead, whether there
    was a ‘‘city charter provision, ordinance, regulation,
    rule, policy, or any other directive [requiring the govern-
    ment official to act in a] prescribed manner.’’ Violano
    v. 
    Fernandez, supra
    , 
    280 Conn. 323
    ; see also Bonington
    v. 
    Westport, supra
    , 
    297 Conn. 308
    (‘‘[t]here is a differ-
    ence between laws that impose general duties on offi-
    cials and those that mandate a particular response to
    specific conditions’’). To the extent that Spitzer v.
    
    Waterbury, supra
    , 
    113 Conn. 84
    , held otherwise, it is
    hereby overruled.
    We conclude, therefore, that the defendants in the
    present case may be held liable to the plaintiffs only if
    there was some legal directive prescribing the specific
    manner in which they were required to maintain and
    repair the town’s storm sewer system. As we have indi-
    cated, the Appellate Court concluded that, ‘‘although
    there is language in § 16-32 of the [Naugatuck Code of
    Ordinances] that requires the streets commission to
    maintain and repair the town’s storm water sewer sys-
    tem, the ordinance contains no provisions that mandate
    the time or manner in which those responsibilities are
    to be executed, leaving such details to the discretion
    and judgment of the municipal employees.’’19 Northrup
    v. 
    Witkowski, supra
    , 
    175 Conn. App. 238
    . The plaintiffs
    do not challenge the Appellate Court’s conclusion that
    the language of that ordinance does not, in and of itself,
    create a ministerial duty.
    Instead, the plaintiffs claim that Witkowski’s deposi-
    tion testimony that the streets commission had devel-
    oped a schedule to ensure that every catch basin was
    maintained at least once a year and that, ‘‘if there were
    calls from the public about a basin being blocked or a
    bad situation that needed to be addressed, we would
    attempt to do that,’’ established the existence of a rule
    or policy that limited the streets commission’s discre-
    tionary authority under § 16-32 of the Naugatuck Code
    of Ordinances and thereby created a ministerial duty.20
    In support of this claim, the plaintiffs argue that, in
    Mills v. Solution, LLC, 
    138 Conn. App. 40
    , 51–52, 
    50 A.3d 381
    , cert. denied, 
    307 Conn. 928
    , 
    55 A.3d 570
    (2012),
    the Appellate Court held that, although the use of the
    mandatory language ‘‘shall’’ in a statute does not neces-
    sarily create a ministerial duty, if the municipality has
    a policy or rule limiting the discretion of public officials
    in the performance of a mandatory duty that would
    otherwise be discretionary, the duty is ministerial.21 We
    are not persuaded that this is a correct interpretation
    of Mills. Rather, Mills is more reasonably interpreted
    as holding that mandatory statutory language is not
    sufficient to create a ministerial duty unless the statute
    itself limits discretion in the performance of the manda-
    tory act. See 
    id., 52 (‘‘[w]here
    the text of the statute
    explicitly vests the chief of police with the discretion
    to determine when and how to furnish police protec-
    tion, we decline to hold that the same statute imposes
    a ministerial duty on the chief of police to furnish the
    protection he deems, in his discretion, to be nec-
    essary’’).
    We need not decide, however, whether the existence
    of a municipal agency’s ‘‘policy or rule’’ that limits the
    agency’s discretion in performing a duty imposed by
    ordinance or statute can ever convert a duty that other-
    wise would be discretionary into a ministerial duty
    because, even if we were to assume, without deciding,
    that there are circumstances under which it can, we
    conclude that Witkowski’s testimony would not be suffi-
    cient to establish the existence of such a policy or rule
    in the present case. This court previously has held that
    a municipality may be held liable for the negligent per-
    formance of a duty only if the ‘‘the official’s duty is
    clearly ministerial.’’ (Emphasis added; internal quota-
    tion marks omitted.) Bonington v. 
    Westport, supra
    , 
    297 Conn. 308
    . We conclude that neither the creation of a
    schedule for cleaning all catch basins at least once per
    year, nor the practice of attempting to respond to every
    complaint about malfunctioning storm drains, consti-
    tutes a ‘‘policy or rule’’ converting the discretionary
    duty to carry out the functions mandated by § 16-32 of
    the Naugatuck Code of Ordinances into a clear ministe-
    rial duty. If we were to conclude otherwise, virtually
    any attempt by a municipal agency to ensure that its
    discretionary duties are regularly and properly carried
    out would convert its discretionary duty into a ministe-
    rial duty, thereby creating a disincentive for municipal
    agencies to make such attempts and undermining the
    very policy considerations that the doctrine governmen-
    tal immunity was intended to advance. See Violano v.
    
    Fernandez, supra
    , 
    280 Conn. 319
    (‘‘[d]iscretionary act
    immunity reflects a value judgment that—despite injury
    to a member of the public—the broader interest in
    having government officers and employees free to exer-
    cise judgment and discretion in their official functions,
    unhampered by fear of second-guessing and retaliatory
    lawsuits, outweighs the benefits to be had from impos-
    ing liability for that injury’’ [internal quotation marks
    omitted]).
    For similar reasons, we reject the plaintiffs’ claim
    that the defendants violated a ministerial duty when
    they completely failed to perform any maintenance or
    repair of some storm drains and catch basins. In support
    of this claim, the plaintiffs rely on this court’s decision
    in Evon v. 
    Andrews, supra
    , 
    211 Conn. 506
    , in which
    we noted that the plaintiffs had not alleged that ‘‘the
    defendants failed to inspect the dwelling’’ but that they
    had ‘‘failed to make reasonable and proper inspections
    . . . .’’ (Emphasis in original; internal quotation marks
    omitted.) The plaintiffs contend that this implies that
    municipalities have no discretion to completely fail to
    perform a mandatory duty, even if the manner of car-
    rying out the duty is discretionary. We disagree. First,
    the plaintiffs have cited no evidence that would support
    a finding that there are town storm drains and catch
    basins that the defendants have never maintained or
    repaired, and the frequency of maintenance and repair
    is discretionary. See Grignano v. 
    Milford, supra
    , 
    106 Conn. App. 656
    (‘‘[a] municipality necessarily makes
    discretionary policy decisions with respect to the tim-
    ing, frequency, method and extent of inspections, main-
    tenance and repairs’’ [emphasis added]). Second, even
    if we were to assume that the defendants never main-
    tained or repaired certain storm drains and catch
    basins, we cannot conclude that, in a system as large
    and complex as a municipal storm drainage system, the
    duty to maintain and repair the system encompasses a
    judicially enforceable duty to maintain and repair each
    individual component of the system, regardless of the
    needs of the system as a whole. It is not the function
    of this court to second-guess the administration of such
    complex municipal affairs, particularly when ‘‘there is
    no readily ascertainable standard by which the action
    of the government servant may be measured . . . .’’22
    (Internal quotation marks omitted.) Violano v. Fernan-
    
    dez, supra
    , 
    280 Conn. 319
    n.7.
    For the foregoing reasons, we conclude that the
    defendants’ duty to maintain and repair the town’s
    storm drains and sewers was discretionary and that
    the Appellate Court properly upheld the trial court’s
    granting of the defendant’s motion for summary judg-
    ment on the ground of governmental immunity.
    The judgment of the Appellate Court is affirmed.
    In this opinion PALMER, McDONALD, D’AURIA and
    KAHN, Js., concurred.

    For the sake of simplicity, we refer to the plaintiffs individually by first
    name when necessary. We also note that the present action was brought
    on Timothy’s behalf by Helen, his mother, as next friend.
    2
    The following officials were named as defendants: (1) Robert A. Mezzo,
    the town’s mayor; (2) Henry J. Witkowski, Jr., who served as the town’s
    superintendent of streets; and (3) James Stewart, who served as town engi-
    neer until 2009, when he was appointed director of the town’s newly formed
    public works department, which replaced the streets commission.

    We granted the plaintiffs’ petition for certification to appeal, limited to
    the following issue: ‘‘Did the Appellate Court properly conclude that the
    maintenance and repair of storm water systems is a discretionary duty, in
    light of this state’s precedents, including Spitzer v. Waterbury, [supra, 
    113 Conn. 84
    ], and Silberstein v. 54 Hillcrest Park Associates, LLC, 135 Conn.
    App. 262,

    (2012)?’’ Northrup v. Witkowski,

    (2017).

    ‘‘In their complaint, the plaintiffs define ‘black water’ as surface rainwater
    that overwhelms and causes a [backup] in the sanitary sewer system,
    resulting in flood waters that contain sewage and other contaminants.’’

    Witkowski, supra

    5
    On appeal to the Appellate Court, the plaintiffs contended that the trial
    court improperly (1) determined that the governmental acts complained of
    were discretionary in nature rather than ministerial, (2) concluded that the
    identifiable person-imminent harm exception to governmental immunity did
    not apply, and (3) raised sua sponte the issue of whether the plaintiffs’
    allegations of recklessness directed against the individual defendants could
    be maintained against them and ultimately concluded that the claims were
    barred by government immunity. Northrup v. 
    Witkowski, supra
    , 175 Conn.
    App. 225–26, 245–46. The Appellate Court rejected all of these claims. 
    Id., 250. The
    Appellate Court’s rulings on the second and third claims are not
    at issue in this certified appeal. See footnote 3 of this opinion.

    After the plaintiffs filed this certified appeal, we granted permission
    to the cities of Bridgeport, Danbury, Hartford, New Haven, Stamford and
    Waterbury to file a joint brief as amicus curiae in support of the defen-
    dants’ position.
    7
    See, e.g., Grignano v. 
    Milford, supra
    , 
    106 Conn. App. 657
    –60 (municipal
    ordinance requiring owner of structure within harbor or marine facility that
    has been found to be dangerous to post proper notice, to construct barricade,
    and to adequately illuminate area until repairs are made created ministerial
    duty); see also Wright v. Brown, 
    167 Conn. 464
    , 471–72, 
    356 A.2d 176
    (1975)
    (statute requiring town dog warden to quarantine dog for fourteen days
    after dog bit person created ministerial duty); Pluhowsky v. New Haven,
    
    151 Conn. 337
    , 347, 
    197 A.2d 645
    (1964) (town clerk has ministerial duty to
    record instrument that has been accepted for recordation in land records);
    Leger v. Kelley, 
    142 Conn. 585
    , 589, 
    116 A.2d 429
    (1955) (statute prohibiting
    commissioner of motor vehicles from registering any motor vehicle that
    was not equipped with safety glass created ministerial duty).
    8
    The plaintiffs do not identify the specific statutes that, according to
    them, impose this ministerial duty. We note, however, that General Statutes
    § 13a-99 provides: ‘‘Towns shall, within their respective limits, build and
    repair all necessary highways and bridges, and all highways to ferries as
    far as the low water mark of the waters over which the ferries pass, except
    when such duty belongs to some particular person. Any town, at its annual
    meeting, may provide for the repair of its highways for periods not exceeding
    five years and, if any town fails to so provide at such meeting, the selectmen
    may provide for such repairs for a period not exceeding one year.’’
    9
    Bronson also states that municipalities may be held liable for damage
    caused by rainwater runoff from roadbeds ‘‘only in special cases, where
    wanton or unnecessary damage is done, or where [the] damage results from
    negligence . . . .’’ Bronson v. 
    Wallingford, supra
    , 
    54 Conn. 520
    . The cases
    cited in Bronson, however, may be characterized as sounding in nuisance.
    See 
    id. As we
    discuss more fully subsequently in this opinion, a municipality
    may be held liable for the creation of a nuisance even when the act that
    created the nuisance was, in the language of the older cases, governmental
    or, in the language of more recent cases, discretionary. Thus, Bronson may
    have conflated the notion that a municipality may be held liable for creating
    a nuisance while carrying out a statutory duty with the notion that a munici-
    pality may be held liable for the performance of nongovernmental acts.
    Suffice it to say that there are a myriad of cases in Connecticut and other
    jurisdictions addressing the issue of municipal liability for damages caused
    by the failure to maintain roads and sewers, and it is likely possible to find
    an isolated case to support any position. See 4 J. Dillon, Commentaries on
    the Law of Municipal Corporations (5th Ed. 1911) § 1740, p. 3051 (‘‘[i]t is,
    perhaps, impossible to reconcile all of the cases’’ on subject of municipal
    liability for damage caused by municipal drains and sewers).
    10
    Remnants of the construct set forth in Dyer and Jones survive in the
    principle that a municipality may be held liable for negligent acts that
    are proprietary in nature, as opposed to governmental. See Considine v.
    Waterbury, 
    279 Conn. 830
    , 844, 
    905 A.2d 70
    (2006) (‘‘municipalities are liable
    for their negligent acts committed in their proprietary capacity’’); see also
    General Statutes § 52-557n (a) (1) (‘‘a political subdivision of the state shall
    be liable for damages to person or property caused by . . . [B] negligence
    in the performance of functions from which the political subdivision derives
    a special corporate profit or pecuniary benefit’’). Although ‘‘the distinction
    between a municipality’s governmental and proprietary functions has been
    criticized as being illusory, elusive, arbitrary, unworkable and a quagmire’’;
    Considine v. 
    Waterbury, supra
    , 845; it is relatively clear that, under the
    more modern rule, not all duties that a municipality voluntarily assumes
    for the benefit of its inhabitants, as distinct from those that it performs for
    the benefit of the general public as the agent of the state, are proprietary
    or, in the language of the older cases, corporate, and, therefore, subject to
    liability. See 
    id., 846 (‘‘functions
    that appear to be for the sole benefit of a
    municipality’s inhabitants, but nevertheless provide indirect benefits to the
    general public because the activities were meant to improve the general
    health, welfare or education of the municipality’s inhabitants’’ are govern-
    mental); 
    id., 848 (‘‘a
    municipality is engaged in a proprietary function when
    it acts very much like private enterprise’’ [internal quotation marks omitted]).
    The plaintiffs in the present case make no claim that the maintenance and
    repair of a storm sewer system is proprietary in nature. Cf. Platt Bros. &
    Co. v. Waterbury, 
    72 Conn. 531
    , 549, 
    45 A. 154
    (1900) (‘‘[w]hile sewers or
    drains for the disposition of surface waters collecting in highways may be
    considered as mere adjuncts of a highway, partaking of its nature as a
    governmental use . . . it is different with sewers for the disposition of
    refuse and filth accumulated on private property’’ [citation omitted; empha-
    sis added]); Brusby v. Metropolitan 
    District, supra
    , 
    160 Conn. App. 653
    (concluding that there was genuine issue of material fact as to whether
    maintenance of sanitary sewer system, of which plaintiff was paying cus-
    tomer, was proprietary function).
    11
    New York state courts continue to accept this distinction between duties
    that are imposed on municipalities and those that they voluntarily assume.
    See Fireman’s Fund Ins. Co. v. Nassau, 
    66 A.D. 3d
    823, 824, 
    887 N.Y.S.2d 242
    (2009) (municipality is immune from liability for negligent
    design of sanitary sewer, but maintenance of sewer is ministerial function);
    Biernacki v. Ravena, 
    245 A.D. 2d
    656, 657, 
    664 N.Y.S.2d 682
    (1997)
    (following Johnston and concluding that, while municipality is not liable
    for defective sanitary sewer plan, construction and repair of sewer are
    ministerial functions).
    12
    The plaintiffs have not cited any Connecticut cases to support their
    position that the construction of sewers is discretionary but that their mainte-
    nance and repair are ministerial. We note that Spitzer itself made no such
    distinction, but indicated that ‘‘[t]he work of constructing drains and sewers,
    as well as that of keeping them in repair, is ministerial . . . .’’ Spitzer v.
    
    Waterbury, supra
    , 
    113 Conn. 88
    . Spitzer also stated, however, that ‘‘the duty
    to provide . . . drains, authorized by the defendant’s charter, is governmen-
    tal in its nature.’’ 
    Id. Because, at
    that time, acts in furtherance of governmen-
    tal or public duties were deemed to be immune from liability, i.e., not
    ministerial; see Gauvin v. New Haven, 
    187 Conn. 180
    , 184, 
    445 A.2d 1
    (1982)
    (citing Spitzer for proposition that ‘‘[a] municipality is immune from liability
    for the performance of governmental acts, as distinguished from ministerial
    acts’’); there would appear to be an inconsistency within Spitzer. This
    apparent inconsistency may reflect the somewhat confusing state of the
    law governing governmental immunity at the time.
    13
    General Statutes § 13a-149 provides in relevant part: ‘‘Any person injured
    in person or property by means of a defective road or bridge may recover
    damages from the party bound to keep it in repair. . . .’’
    14
    Dillon’s treatise also relied on the now outmoded distinction between
    public duties, which are imposed on municipalities, and corporate duties,
    which municipalities voluntarily assume. See 4 J. Dillon, supra, § 1742, p.
    3057 n.1.
    15
    We note that Spitzer cited Judd and Mootry in support of its conclusion
    that a municipality is ‘‘bound to exercise due care in the construction of
    its storm water sewers, and would be liable for its failure to do so . . . .’’
    Spitzer v. 
    Waterbury, supra
    , 
    113 Conn. 88
    .
    16
    This court stated in Elliott v. Waterbury, 
    245 Conn. 385
    , 421, 
    715 A.2d 27
    (1998), that, ‘‘in order to overcome the governmental immunity of municipal
    defendants where it applies, the plaintiff must prove that the defendants,
    by some positive act, intentionally created the conditions alleged to consti-
    tute a nuisance.’’ (Emphasis added.) In support of this statement, this court
    cited, among other cases, Keeney v. Old 
    Saybrook, supra
    , 
    237 Conn. 165
    –66,
    and Hoffman v. 
    Bristol, supra
    , 
    113 Conn. 390
    –92. See Elliott v. 
    Waterbury, supra
    , 421. In both Keeney and Hoffman, however, this court expressly
    recognized that a municipality may be held liable for negligently creating
    a nuisance. See Keeney v. Old 
    Saybrook, supra
    , 165 (municipality may be
    held liable for nuisance even if its conduct ‘‘constitutes negligence from
    which the municipality would be immune’’); Hoffman v. 
    Bristol, supra
    , 389
    (municipality may be held liable for nuisance ‘‘irrespective of whether the
    misfeasance or nonfeasance causing the nuisance also constituted negli-
    gence’’); see also Judd v. 
    Hartford, supra
    , 
    72 Conn. 353
    (municipality was
    liable when, ‘‘after planning and constructing an adequate sewer, [the munici-
    pality] left obstructions in it, placed there for temporary purposes, which
    its agents carelessly omitted to remove after those purposes had been accom-
    plished’’ [emphasis added]). It is clear, therefore, that, by using the word
    ‘‘intentionally,’’ Elliott merely intended to emphasize that, for a municipality
    to be held liable for creating a nuisance, the nuisance must be the result
    of some positive act of the municipality, and that this court did not intend
    to suggest that only the intentional act of a municipality can create a nui-
    sance. In other words, there is a difference between a positive act, which
    may be negligent, as was the act of the municipality in Judd, and an inten-
    tional act.
    17
    The plaintiffs in the present case have made no claim that the defendants
    may be held liable for their failure to properly maintain and repair the storm
    sewer system under a nuisance theory because a positive act by the town
    caused damage to their property. Indeed, at oral argument before this court,
    counsel for the plaintiffs conceded that he did not believe that the facts of
    this case would support a nuisance claim. See Aerotec Corp. v. 
    Greenwich, supra
    , 
    138 Conn. 120
    (noting that municipal liability for nuisance ‘‘exists
    . . . only for those nuisances which have been created by positive act’’ and
    that ‘‘[t]here is no liability where the condition of the highway which is
    dangerous has come into being simply because of the failure of the town
    to take remedial steps’’); Karnasiewicz v. New Britain, 
    131 Conn. 691
    , 694,
    
    42 A.2d 32
    (1945) (when dangerous highway condition does not constitute
    defect under highway defect statute and does not constitute nuisance, ‘‘a
    municipality is not liable where its sole fault is a failure to take remedial
    steps’’); see also footnote 18 of this opinion.
    These decisions lend support to our conclusion that the maintenance and
    repair of a storm drainage system are not ministerial functions. It would be
    odd to conclude that a city is not liable for harms caused by a dangerous
    condition on a highway unless the condition was created by a positive act
    of the municipality or constituted a defect under the highway defect statute,
    but the city may be held liable for harms caused by the failure to take steps
    to remedy a dangerous condition in a storm drainage system.
    18
    We recognize that this court has held that, by enacting § 52-557n, the
    legislature eliminated common-law actions against municipalities arising
    from injuries for which § 13a-149, the highway defect statute, provides a
    remedy, including nuisance actions. See Sanzone v. Board of Police Commis-
    sioners, 
    219 Conn. 179
    , 192, 
    592 A.2d 912
    (1991) (§ 52-557n provides that
    § 31a-149 ‘‘is a plaintiff’s exclusive remedy against a municipality or other
    political subdivision ‘for damages resulting from injury to any person or
    property by means of a defective road or bridge’ ’’); see also General Statutes
    § 52-557n (a) (1) (providing that municipality may be held liable for its
    negligent acts and negligent acts of its employees acting within scope of
    official duties, for acts from which political subdivision derives corporate
    profit, and for creation of nuisance, ‘‘provided, no cause of action shall be
    maintained for damages resulting from injury to any person or property by
    means of a defective road or bridge except pursuant to section 13a-149’’).
    As we have indicated herein, however, § 13a-149 does not provide a right
    of recovery to an abutting landowner for damage to the land caused by a
    defective highway. See Aerotec Corp. v. 
    Greenwich, supra
    , 
    138 Conn. 119
    .
    Moreover, a highway need not be defective to constitute a nuisance to
    abutting landowners. See Wright v. 
    Brown, supra
    , 
    167 Conn. 470

    Section 16-32 of the Naugatuck Code of Ordinances provides: ‘‘Except
    as otherwise provided in this article, the streets commission shall be respon-
    sible for the care and management of all streets, avenues, highways, alleys
    and bridges, and the opening, [grading, improving], repairing and cleaning
    of the same; of the construction, protection, repair, furnishing, cleaning,
    heating, lighting and general care of all public streets and appurtenances,
    except such as are by the express terms of the Charter under the control
    of some other officer or department; of the construction, repair, cleaning
    and general care of all drains, culverts, sluiceways and catch basins, and
    the collection and disposing of ashes, garbage and refuse. The streets com-
    mission shall make all suitable rules and regulations in regard to the depart-
    ment and the conduct of its business.’’

    The plaintiffs raised this claim for the first time in their reply brief.
    They contend that they did not raise this claim in their main brief because
    ‘‘the question certified by this [court] was not specific to the [town’s] direc-
    tives, but to storm water systems in general . . . .’’ They point out that the
    defendants nevertheless addressed ‘‘the question more narrowly as it relates
    only to the [town].’’ The plaintiffs fail to recognize, however, that this court
    is required to reach the question of whether the defendants’ own acts had
    created a ministerial duty only if it rejects their claim that a ministerial duty
    was created by statute and that our review of the former issue can only be
    to their benefit. By failing to address the issue in their main brief, the
    plaintiffs effectively abandoned it. See, e.g., State v. Jose G., 
    290 Conn. 331
    ,
    341 n.8, 
    963 A.2d 42
    (2009) (‘‘[i]t is a well established principle that arguments
    cannot be raised for the first time in a reply brief’’ [internal quotation marks
    omitted]). Nevertheless, because the plaintiffs cannot prevail on this claim,
    and because the defendants have briefed it, we review it. See Blumberg
    Associates Worldwide, Inc. v. Brown & Brown of Connecticut, Inc., 
    311 Conn. 123
    , 157–58, 
    84 A.3d 840
    (2014) (review of unpreserved claim may
    be appropriate when party who raised it cannot prevail).

    (2012) (although no legal directive prescribed specific manner in which
    tree warden was required to perform duties, evidence that town’s assistant
    director of public works had repeatedly provided same general direction to
    tree warden upon receiving complaints of unsafe trees and tree warden’s
    testimony that he had nondiscretionary duty to perform inspection upon
    receipt of complaint were sufficient to establish ministerial duty); Kolaniak
    v. Board of Education, 
    28 Conn. App. 277
    , 281, 
    610 A.2d 193
    (1992) (in case
    in which board of education had issued bulletin to all maintenance personnel
    directing that walkways were to be inspected and kept clean on daily basis,
    maintenance workers had no discretion to determine whether there was
    sufficient accumulation of snow before clearing walkways but had ministe-
    rial duty to clear walkways of snow and ice).

    The dissenting justice would conclude that, because ‘‘[o]nly the munici-
    pality can construct a storm water drainage system and, once constructed,
    only the municipality can maintain the system and repair it to prevent
    property damage foreseeably resulting from its malfunction,’’ and ‘‘[b]ecause
    storm water drainage systems are municipal property and subject to exclu-
    sive municipal control,’’ a municipality should not be permitted to invoke
    municipal immunity to ‘‘escape liability.’’ (Internal quotation marks omitted.)
    The very purpose of the doctrine of governmental immunity, however, is
    to bar liability for harmful negligent conduct by a municipality, and it is in
    the very nature of harmful negligent conduct that the harm was within the
    power of the tortfeasor to prevent. Thus, to create an exception to the
    doctrine in cases in which the dangerous condition was within the municipal-
    ity’s control and the municipality could have prevented the harm would
    eviscerate the doctrine, and would entirely disregard the underlying ‘‘value
    judgment that—despite injury to a member of the public—the broader inter-
    est in having government officers and employees free to exercise judgment
    and discretion in their official functions, unhampered by fear of second-
    guessing and retaliatory lawsuits, outweighs the benefits to be had from
    imposing liability for that injury.’’ (Internal quotation marks omitted.) Vio-
