    OPINION
    ¶1          The instant appeal arises from a lawsuit filed by plaintiffs concerning property damage to
    their homes resulting from storm water flooding. Plaintiffs, who reside in Maine Township,
    No. 1-17-0859
    allege that defendant, Advocate Health and Hospitals Corporation (Advocate), which
    operates a hospital adjacent to plaintiffs’ neighborhood, constructed its hospital in such a way
    that the hospital’s storm water drainage system discharged onto plaintiffs’ properties and
    caused flooding. Plaintiffs further allege that the local public entities, namely, the Village of
    Glenview (Glenview), Maine Township, the Metropolitan Water Reclamation District of
    Greater Chicago (District), the Village of Niles (Niles), and the City of Park Ridge (Park
    Ridge), 1 breached a variety of duties owed to the homeowners with respect to the drainage
    system. The defendants participating in the instant appeal—Park Ridge, the District, and
    Maine Township—sought dismissal of the complaint on the basis of the public duty rule,
    claiming that they did not owe a duty to any individual plaintiff but only to the community at
    large. In 2015, the trial court dismissed the complaint pursuant to section 2-615 of the Code
    of Civil Procedure (Code) (735 ILCS 5/2-615 (West 2014)), finding that the public duty rule
    applied. However, in 2016, the Illinois Supreme Court abolished the public duty rule in
    Coleman v. East Joliet Fire Protection District, 
    2016 IL 117952
    , and the trial court granted
    plaintiffs’ motion to reconsider. Six months later, however, the trial court vacated its order
    and reinstated the dismissal. Plaintiffs now appeal, arguing that the supreme court’s decision
    should be applied retroactively and the public duty rule is not available to defendants, and
    further arguing that no other basis existed for dismissing their complaint. For the reasons that
    follow, we affirm in part and reverse in part.
    1
    Cook County was also named as a defendant, but plaintiffs voluntarily dismissed the counts
    aimed at the county without prejudice on April 25, 2013. Glenview was voluntarily dismissed from
    the case with prejudice on December 12, 2014. Niles is not a party to the instant appeal, but the trial
    court’s dismissal expressly encompassed Niles, as well.

    ¶2                                         BACKGROUND
    ¶3         We considered the complaint with respect to defendant Advocate in Tzakis v. Advocate
    Health & Hospitals Corp., 
    2015 IL App (1st) 142285-U
    . As it is the same complaint at issue
    in both appeals—plaintiffs’ “amended fifth amended complaint”—we incorporate our prior
    description of the allegations where applicable in the instant appeal.
    ¶4         Plaintiffs filed their amended fifth amended complaint on January 20, 2012. According to
    the complaint, Park Ridge, Cook County, Maine Township, and the District, “among other
    local public entities,” in coordination with private partners, developed the Prairie Creek
    Stormwater System, which was a manmade storm water system of drains, retention basins,
    and storm water sewers, and the local public entities controlled the development of the
    system beginning with the original 1960 plat approvals. The Prairie Creek Stormwater
    System received most of the storm water runoff within the Prairie Creek Watershed, a
    watershed of over one mile, extending upstream from plaintiffs’ homes. Advocate acquired a
    parcel of real property adjacent to plaintiffs’ neighborhood some time prior to 1976, which
    was also located within the watershed; as one of the parties admitted in oral argument, the
    property was on a flood plain. In 1976, Advocate submitted a development plan to Park
    Ridge that proposed modifications to Advocate’s drainage system. Park Ridge approved the
    plans and they were subsequently implemented. In October 1976, the Illinois Department of
    Transportation issued a report stating that “a large portion of the subdivision set out in
    [Advocate’s development plan],” including plaintiffs’ neighborhood, “was and is subject to
    flood risks.”
    ¶5         According to the complaint, in 1987, plaintiffs’ neighborhood sustained catastrophic
    flooding, in response to which Park Ridge, Maine Township, and Glenview, “along with
    3
    No. 1-17-0859
    other entities,” hired Harza Engineering Services (Harza) to investigate the flooding. In 1990,
    Harza issued a report that identified design and maintenance defects in Advocate’s drainage
    system, including the portions adjacent to plaintiffs’ properties. The report indicated that
    these defects impaired the system’s drainage capacity to a level “substantially below any
    reasonably safe standard.” Plaintiffs allege that Harza’s report placed Park Ridge, Maine
    Township, and Glenview and “possibly other [defendants]” on actual or constructive
    knowledge of the flood risk to plaintiffs’ homes.
    ¶6         The complaint alleges that sometime after 1987 but before 2002, Advocate hired Gewalt
    Hamilton Associates, Inc. (Gewalt), an engineering firm, to draft and implement a
    development plan for the hospital property that included modifications to the drainage system
    and topography that altered the property’s “natural drainage areas.” In August 2002, a
    rainstorm caused storm water to accumulate within the hospital’s drainage system. Plaintiffs
    allege that an “undersized” discharge component caused water to build up and
    “catastrophically overflow” the drainage system, again flooding plaintiffs’ homes.
    ¶7         The complaint alleges that in 2002 or 2003, the Illinois Department of Natural Resources
    conducted a study in response to the 2002 flooding in conjunction with local municipal
    authorities, including Park Ridge, Maine Township, and Glenview. The study found
    “numerous bottlenecks and obstructions to flow as the causes of the invasive flooding.” The
    study also detailed potential remedies, including specific improvements to Advocate’s
    drainage system. After 2002 but before September 13, 2008, Advocate and Gewalt developed
    plans to modify the hospital property’s drainage system, including components identified as
    problematic in the 2002 study. However, plaintiffs allege that, on information and belief,
    Advocate’s plan did not include modifications to three undersized components of the
    4
    No. 1-17-0859
    drainage system, despite Advocate’s knowledge of the flood risk these components posed to
    plaintiffs. On September 13, 2008, storm water overwhelmed the hospital’s drainage system
    and caused the flooding in plaintiffs’ homes and property, leading to the instant lawsuit. 2
    ¶8          With respect to the District, the complaint alleged that the District was the regional local
    public entity charged with multijurisdiction operation of storm water management and “owns
    and/or controls all drains, basins, structures, components and other stormwater
    improvements” within the Prairie Creek Stormwater System. The complaint further alleged
    that the District owned and operated the interceptors that received sewage from local sanitary
    sewers owned and controlled by Glenview and Park Ridge and transported it for treatment to
    one of the District’s wastewater treatment plants. With respect to Park Ridge, the complaint
    alleged that Park Ridge had the most actual knowledge of Advocate flooding and was in the
    best position to make changes to Advocate’s plans for its drainage system but failed to
    demand that Advocate make the necessary changes. The complaint further alleged that Park
    Ridge did not advise the District of the flooding problems and that Park Ridge deployed its
    police and/or department of public safety to the area during instances of flooding. With
    respect to Maine Township, the complaint alleged that the Maine Township Highway
    Department had mobilized and readied trucks for sand delivery to plaintiffs’ neighborhood in
    anticipation of the September 13, 2008, flooding and had provided sandbags “[o]n many
    prior occasions” when there had been catastrophic flooding. The complaint further alleged
    that Maine Township was responsible for storm water management within its jurisdiction and
    supervised all storm water management projects and that, through its exercise of control,
    2
    While the lawsuit at issue in the instant appeal is limited to the September 13, 2008, flooding,
    four other lawsuits were filed after subsequent flooding events; these four lawsuits were consolidated
    for all purposes with the instant lawsuit, and the trial court’s dismissal expressly applied to all of the
    lawsuits.
    5
    No. 1-17-0859
    Maine Township “owned possessed and/or controlled” the portions of the Prairie Creek
    Stormwater System within its jurisdiction.
    ¶9          The complaint alleged similar causes of action against all three defendants. 3 Counts XXV
    (against the District), XLV (against Park Ridge), and LXIV (against Maine Township) were
    for “negligence: dominant estate overburdening stormwater” and alleged that defendants
    knew or should have known of the foreseeable harm of invasive flooding into plaintiffs’
    neighborhood given the history of flooding, and that defendants owed nondelegable duties to
    properly manage the storm water so as to prevent harm to plaintiffs from excess storm water
    overburdening the drainage system. Counts XXXI (against the District), LII (against Park
    Ridge), and LXIX (against Maine Township) were for “negligent nuisance” and alleged that
    defendants negligently caused an accumulation of water from the drainage system to invade
    and interfere with plaintiffs’ property. Counts XXXII (against the District), LIII (against Park
    Ridge), and LXX (against Maine Township) were for “negligent trespass” and alleged that,
    due to defendants’ failure to properly manage the storm water systems, water invaded
    plaintiffs’ property. Counts XXXVI (against the District), LVII (against Park Ridge), and
    LXXIV (against Maine Township) were for “statutory duty to maintain property” and alleged
    that section 3-102(a) of the Local Governmental and Governmental Employees Tort
    Immunity Act (Tort Immunity Act) (745 ILCS 10/3-102(a) (West 2012)) set forth a duty for
    a local public entity to exercise ordinary care to maintain its property in a reasonably safe
    condition, which defendants did not do. Counts XXXVII (against the District), LVIII (against
    Park Ridge), and LXXV (against Maine Township) were for “duty to remedy dangerous
    plan” and alleged that section 3-103 of the Tort Immunity Act (745 ILCS 10/3-103 (West
    3
    The complaint also contained a number of additional counts against defendants, but plaintiffs
    voluntarily dismissed several of them and, in response to defendants’ motions to dismiss, indicated
    that they would be “proceeding only upon” the counts we discuss herein.
    6
    No. 1-17-0859
    2012)) set forth a duty for a local public entity to correct known unsafe conditions related to
    the design and/or engineering of an approved plan, which defendants did not do. Counts
    XXXIX (against the District), LX (against Park Ridge), and LXXVI (against Maine
    Township) were for “taking real and personal property” and were based on article I, section
    15, of the Illinois Constitution (Ill. Const. 1970, art. I, § 15), which prohibited the taking of
    private property for public use without the payment of just compensation.
    ¶ 10         On August 15, 2014, Park Ridge, the District, and Maine Township each filed motions to
    dismiss plaintiffs’ amended fifth amended complaint. 4 Each of the motions to dismiss
    claimed that the complaint should be dismissed under section 2-615 of the Code because
    plaintiffs’ claims were barred under the public duty rule and plaintiffs had failed to allege the
    existence of any duties owed to them. Each of the motions to dismiss further claimed that the
    complaint should be dismissed under section 2-619 of the Code because defendants were
    immune from liability pursuant to several sections of the Tort Immunity Act.
    ¶ 11         On April 3, 2015, the trial court granted defendants’ motion to dismiss pursuant to
    section 2-615 based on the public duty rule. The court found that the public duty rule applied
    to all of defendants’ alleged conduct, and that no special duty exception applied.
    Accordingly, the court found that plaintiffs had not alleged sufficient facts to infer the
    existence of an actionable duty on the part of defendants and granted the motions to dismiss.
    ¶ 12         On May 4, 2015, defendants filed a motion for a finding that there was no just reason to
    delay enforcement or appeal from the trial court’s April 3, 2015, order. In response, plaintiffs
    4
    The District and Maine Township each filed a combined motion to dismiss pursuant to section 2-
    619.1 of the Code (735 ILCS 5/2-619.1 (West 2012)), while Park Ridge filed two separate motions to
    dismiss, one based on section 2-615 (735 ILCS 5/2-615 (West 2012)) and one based on section 2-619
    (735 ILCS 5/2-619 (West 2012)).
    7
    No. 1-17-0859
    claimed that the trial court’s order did not encompass its counts concerning the takings
    clause, and the parties engaged in briefing and oral argument on the issue.
    ¶ 13         On January 22, 2016, the Illinois Supreme Court issued a decision in Coleman, 
    2016 IL 117952
    , in which it abolished the public duty rule. On February 8, 2016, plaintiffs filed a
    motion for reconsideration of the dismissal of the complaint based on Coleman. Plaintiffs
    claimed that, as an interlocutory order, the trial court was permitted to review, modify, or
    vacate such an order at any time. In response, defendants argued that the new law established
    in Coleman should not be applied retroactively.
    ¶ 14         On August 18, 2016, the trial court granted plaintiffs’ motion for reconsideration and
    vacated its April 3, 2015, order. Defendants filed a motion requesting that the trial court
    certify the issue for interlocutory appeal. On February 1, 2017, in its order on that motion, the
    trial court “on its own motion, reconsider[ed] its order of August 18, 2016.” The court noted
    that, in their briefing on the issue of certification, defendants included arguments that had not
    been presented in the briefing on plaintiffs’ motion to reconsider and found that “[t]hose
    additional arguments have persuaded this Court to vacate paragraph 1 of the August 18, 2016
    order and reinstate its decision of April 3, 2015 dismissing [defendants].” The court found
    that the new law set forth in Coleman should not be retroactively applied to the instant case.
    The court noted that defendants had been raising the public duty rule since their initial
    motion to dismiss in 2010 and continued to raise the issue in subsequent motions to dismiss
    and found that retroactive application of the law would involve substantially more litigation
    preparation than could have been predicted. The court found that “[t]his is a hardship on the
    [defendants] and their taxpayers considering the unpredictable and unexpected reversal of
    longstanding law, the complexity of the case, and the passage of time.”
    8
    No. 1-17-0859
    ¶ 15         On February 14, 2017, defendants filed a motion for a finding pursuant to Illinois
    Supreme Court Rule 304(a) (eff. Mar. 8, 2016) that there was no just reason for delaying
    enforcement or appeal of the February 1, 2017, order reinstating the dismissal of plaintiffs’
    complaint with respect to defendants; this motion was granted on March 10, 2017. Plaintiffs
    filed a notice of appeal on April 4, 2017, and this appeal follows.
    ¶ 16                                            ANALYSIS
    ¶ 17         On appeal, plaintiffs claim that the trial court erred in finding that Coleman should not
    apply retroactively to their claims. Additionally, plaintiffs claim that, in the absence of the
    public duty rule, there was no alternate basis for dismissing their complaint.
    ¶ 18                                       I. Standard of Review
    ¶ 19         The trial court’s dismissal of plaintiffs’ complaint was based on section 2-615 of the
    Code. A motion to dismiss under section 2-615 of the Code challenges the legal sufficiency
    of the complaint by alleging defects on its face. Young v. Bryco Arms, 
    213 Ill. 2d 433
    , 440
    (2004); Wakulich v. Mraz, 
    203 Ill. 2d 223
    , 228 (2003). The critical inquiry is whether the
    allegations in the complaint are sufficient to state a cause of action upon which relief may be
    granted. Wakulich, 
    203 Ill. 2d at 228
    . A cause of action will not be dismissed on the
    pleadings unless it clearly appears that the plaintiff cannot prove any set of facts that will
    entitle it to relief. Board of Directors of Bloomfield Club Recreation Ass’n v. The Hoffman
    Group, Inc., 
    186 Ill. 2d 419
    , 424 (1999). In making this determination, all well-pleaded facts
    in the complaint and all reasonable inferences that may be drawn from those facts are taken
    as true. Young, 
    213 Ill. 2d at 441
    . In addition, we construe the allegations in the complaint in
    the light most favorable to the plaintiff. Young, 
    213 Ill. 2d at 441
    . We review de novo an
    order granting a section 2-615 motion to dismiss. Young, 
    213 Ill. 2d at 440
    ; Wakulich, 203
    9
    No. 1-17-0859
    Ill. 2d at 228. De novo consideration means we perform the same analysis that a trial judge
    would perform. Khan v. BDO Seidman, LLP, 
    408 Ill. App. 3d 564
    , 578 (2011). Additionally,
    even if the trial court dismissed on an improper ground, a reviewing court may affirm the
    dismissal if the record supports a proper ground for dismissal. See Raintree Homes, Inc. v.
    Village of Long Grove, 
    209 Ill. 2d 248
    , 261 (2004) (we can affirm “on any basis present in
    the record”); In re Marriage of Gary, 
    384 Ill. App. 3d 979
    , 987 (2008) (“we may affirm on
    any basis supported by the record, regardless of whether the trial court based its decision on
    the proper ground”).
    ¶ 20         Additionally, each defendant also filed a motion to dismiss the amended fifth amended
    complaint pursuant to section 2-619 of the Code. A motion to dismiss under section 2-619
    admits the legal sufficiency of all well-pleaded facts but allows for the dismissal of claims
    barred by an affirmative matter defeating those claims or avoiding their legal effect. Janda v.
    United States Cellular Corp., 
    2011 IL App (1st) 103552
    , ¶ 83 (citing DeLuna v. Burciaga,
    
    223 Ill. 2d 49
    , 59 (2006)). When reviewing a motion to dismiss under section 2-619, “a court
    must accept as true all well-pleaded facts in plaintiffs’ complaint and all inferences that can
    reasonably be drawn in plaintiffs’ favor.” Morr-Fitz, Inc. v. Blagojevich, 
    231 Ill. 2d 474
    , 488
    (2008). Additionally, a cause of action should not be dismissed under section 2-619 unless it
    is clearly apparent that no set of facts can be proved that would entitle the plaintiff to relief.
    Feltmeier v. Feltmeier, 
    207 Ill. 2d 263
    , 277-78 (2003). For a section 2-619 dismissal, our
    standard of review is de novo. Solaia Technology, LLC v. Specialty Publishing Co., 
    221 Ill. 2d 558
    , 579 (2006); Morr-Fitz, Inc., 
    231 Ill. 2d at 488
    . As noted, de novo consideration
    means we perform the same analysis that a trial judge would perform. Khan, 408 Ill. App. 3d
    at 578.

    ¶ 21                                       II. Public Duty Rule
    ¶ 22         In the case at bar, as noted, the trial court’s dismissal was based on its finding that
    defendants owed no duties to plaintiffs due to the public duty rule. Accordingly, it is helpful
    to begin with an overview of the public duty rule and the impact of the supreme court’s 2016
    decision in Coleman. The common law public duty rule provides that local governmental
    entities do not owe any duty to individual members of the general public to provide adequate
    governmental services, such as police and fire protection. Coleman, 
    2016 IL 117952
    , ¶ 37.
    “The long-standing public duty rule is grounded in the principle that the duty of the
    governmental entity to preserve the well-being of the community is owed to the public at
    large rather than to specific members of the community.” (Internal quotation marks omitted.)
    Coleman, 
    2016 IL 117952
    , ¶ 38. An exception to this rule is the “special duty exception,”
    where the local governmental entity owes a special duty of care to a particular individual that
    is different from the duty it owes to the general public. Coleman, 
    2016 IL 117952
    , ¶ 41.
    ¶ 23         In its analysis, the Coleman court traced the origins of the public duty rule to either an
    1855 United States Supreme Court case or to an 1880 treatise on tort law. Coleman, 
    2016 IL 117952
    , ¶¶ 39, 40. The court further noted that the doctrine “was widely accepted in most
    jurisdictions.” Coleman, 
    2016 IL 117952
    , ¶ 41. The Coleman court noted that the Illinois
    Supreme Court first acknowledged the public duty rule and its special duty exception in
    1968. Coleman, 
    2016 IL 117952
    , ¶ 42. The court further noted that the public duty rule
    “existed ‘[i]ndependent[ly] of statutory or common-law concepts of sovereign immunity.’ ”
    Coleman, 
    2016 IL 117952
    , ¶ 44 (quoting Huey v. Town of Cicero, 
    41 Ill. 2d 361
    , 363
    (1968)). The court, thus, noted that “[w]e have consistently held that the public duty rule
    survived the abolition of sovereign immunity and passage of the Tort Immunity Act.”
    11
    No. 1-17-0859
    Coleman, 
    2016 IL 117952
    , ¶ 52. Nevertheless, the Coleman court held that “the time has
    come to abandon the public duty rule and its special duty exception.” 5 Coleman, 
    2016 IL 117952
    , ¶ 52. Accordingly, the court held that “in cases where the legislature has not
    provided immunity for certain governmental activities, traditional tort principles apply.”
    Coleman, 
    2016 IL 117952
    , ¶ 61.
    ¶ 24          As an initial matter, in the case at bar, plaintiffs present shifting arguments concerning
    the applicability of the public duty rule to the creation and operation of municipal sewer and
    drainage systems. We note that most of these arguments are raised for the first time in
    plaintiffs’ reply brief and, in some cases, at oral argument. It is well settled that points not
    argued in the appellant’s brief are forfeited. Lebron v. Gottlieb Memorial Hospital, 
    237 Ill. 2d 217
    , 253 (2010); Ill. S. Ct. R. 341(h)(7) (eff. May 25, 2018) (“Points not argued [in the
    appellant’s brief] are forfeited and shall not be raised in the reply brief, in oral argument, or
    on petition for rehearing.”). Accordingly, any arguments not raised in plaintiffs’ initial brief
    are not properly before this court. Nevertheless, we will briefly address some of those
    arguments below.
    ¶ 25          In their briefs, plaintiffs argue that the public duty rule is inapplicable because it is
    preempted by the Tort Immunity Act. However, our supreme court has repeatedly maintained
    that the public duty rule and the Tort Immunity Act may properly coexist. See, e.g.,
    Coleman, 
    2016 IL 117952
    , ¶ 52; Zimmerman v. Village of Skokie, 
    183 Ill. 2d 30
    , 45 (1998);
    Harinek v. 161 North Clark Street Ltd. Partnership, 
    181 Ill. 2d 335
    , 346 (1998); Huey, 
    41 Ill. 5
    While we refer to the “Coleman court,” the decision in Coleman was a split one, with no
    majority opinion. Four justices concurred in the judgment, agreeing to abolish the public duty rule.
    However, the lead opinion was joined by the author and another justice, with two other justices
    joining in a special concurrence. Three justices dissented, believing that the public duty rule should
    not be abolished. For purposes of this appeal, however, the only relevant fact is that the public duty
    rule has been abolished.
    12
    No. 1-17-0859
    2d at 363. Additionally, in their reply brief, plaintiffs argue that the public duty rule has
    “never been applied to [a local public entity] which actually owned the sewer or drain.”
    (Emphases omitted.) 6 Even assuming arguendo that plaintiffs are correct, plaintiffs fail to
    explain the relevance of defendants’ ownership of the pipes. We note that our supreme court
    has found that the distinction between a governmental unit’s governmental and proprietary
    functions was abandoned upon the abolishment of sovereign immunity. In re Chicago Flood
    Litigation, 
    176 Ill. 2d 179
    , 192 (1997). Accordingly, we cannot find that the ownership of the
    pipes would have any impact on the applicability of the public duty rule. 7 Plaintiffs then
    argue that operation of storm water sewer systems is not considered “ ‘flood prevention’ or
    ‘flood relief’ services.” Again, even assuming arguendo that plaintiffs are correct, it is
    irrelevant to the question of whether the public duty rule applies, as the rule is not limited to
    flood prevention or flood relief services. See, e.g., Harinek, 
    181 Ill. 2d at 345
     (“the public
    duty rule *** prevents [governmental] units from being held liable for their failure to provide
    adequate governmental services”).
    ¶ 26          In their reply brief, plaintiffs next claim that the 1897 supreme court case of City of
    Chicago v. Seben, 
    165 Ill. 371
     (1897), provides that “a [local public entity] acts ministerial
    without immunity when constructing, maintaining and operating sewers in executing its
    plan.” However, whether a governmental entity’s action is discretionary or ministerial is an
    issue with respect to application of the Tort Immunity Act, as plaintiffs themselves implicitly
    6
    In their opening brief, plaintiffs also argue that the supreme court has never applied the public
    duty rule to “trespassory water invasion” as part of their argument for retroactive application of
    Coleman. We discuss that argument later in our analysis on the retroactivity issue.
    7
    We note that our supreme court has suggested that an exception to the public duty rule may
    apply where the government is acting in a private, as opposed to a governmental, capacity. Burdine v.
    Village of Glendale Heights, 
    139 Ill. 2d 501
    , 508 (1990), overruled in part on other grounds, McCuen
    v. Peoria Park District, 
    163 Ill. 2d 125
     (1994). However, plaintiffs do not claim that defendants in the
    case at bar were acting in a private capacity.
    13
    No. 1-17-0859
    recognize through their reference to “immunity.” Our supreme court has made clear that
    “[t]he existence of a duty and the existence of an immunity *** are separate issues.” Village
    of Bloomingdale v. CDG Enterprises, Inc., 
    196 Ill. 2d 484
    , 490 (2001); see also Van Meter v.
    Darien Park District, 
    207 Ill. 2d 359
    , 370 (2003); Harinek, 
    181 Ill. 2d at 346
    ; Zimmerman,
    
    183 Ill. 2d at 46
    . The court first determines whether a duty exists, then addresses whether the
    governmental entity is immune from liability for a breach of that duty. Village of
    Bloomingdale, 
    196 Ill. 2d at 490
    ; Harinek, 
    181 Ill. 2d at 346
     (“the question of whether the
    City owed plaintiff a duty under the special duty doctrine has no bearing on the separate
    question of whether the [Tort Immunity] Act immunizes the City from liability for plaintiff’s
    injuries”); Zimmerman, 
    183 Ill. 2d at 46
     (“The distinction between an immunity and a duty is
    crucial, because only if a duty is found is the issue of whether an immunity or defense is
    available to the governmental entity considered ***.”). Thus, whether an action is
    discretionary or ministerial has no impact on whether a duty exists in the first instance.
    ¶ 27         Moreover, plaintiffs’ reliance on Seben shifted during oral argument. There, plaintiffs’
    counsel stated that “the public duty rule has been rejected by the supreme court explicitly in
    Seben in 1898 [sic] when they rejected the Michigan rule.” As noted, points not argued in the
    appellant’s brief are forfeited. Lebron, 
    237 Ill. 2d at 253
    ; Ill. S. Ct. R. 341(h)(7) (eff. May 25,
    2018) (“Points not argued [in the appellant’s brief] are forfeited and shall not be raised in the
    reply brief, in oral argument, or on petition for rehearing.”). Consequently, the argument
    plaintiffs raised for the first time at oral argument is not properly before this court.
    Furthermore, plaintiffs’ counsel vastly overstated the Seben court’s findings. In that case, the
    supreme court affirmed the trial court’s refusal to give jury instructions providing that the
    City of Chicago could not be held liable for an injury caused by the plaintiff’s stepping into a
    14
    No. 1-17-0859
    sewer inlet where the sewer was constructed as part of a plan that was devised through no
    error in judgment. Seben, 165 Ill. at 383. The court found that the proposed jury instructions
    focused on only the initial construction of the sewer, and not on whether it was properly
    maintained. Seben, 165 Ill. at 383. In its discussion, the supreme court rejected the city’s
    reliance on the “Michigan doctrine,” which provided that where an injury was caused by the
    implementation of a plan that would render the work dangerous when completed, the fault
    lay with the legislature and that a “suit grounded upon it is grounded upon a wrong
    attributable to the legislative body itself.” Seben, 165 Ill. at 380. The court further noted that
    Michigan had adopted the public duty rule—although it did not use that term—and did not
    draw a distinction between the liability of cities and the liability of towns and counties.
    Seben, 165 Ill. at 380.
    ¶ 28         The Seben court’s discussion of these latter two points highlights the flaws with
    plaintiffs’ characterization of the case at oral argument. As noted, Seben was decided in
    1897, and the law in Illinois at that time was significantly different than it is today. As the
    Coleman court explained, the public duty rule originated in either 1855 or 1880, and our
    supreme court first expressly recognized the rule in 1968. Coleman, 
    2016 IL 117952
    , ¶¶ 39-
    40, 42. Thus, at the time that the Seben court issued its decision, the public duty rule itself
    was comparatively recent law, and the supreme court had never discussed it, much less
    “rejected” it “explicitly,” as plaintiffs’ counsel suggested at oral argument. Additionally, at
    that time, Illinois still retained local governmental tort immunity, which remained the state of
    the law until it was abolished in 1959. See Coleman, 
    2016 IL 117952
    , ¶¶ 30-33 (discussing
    the history of local governmental tort immunity). Thus, the liability of a local governmental
    entity established by the State differed from the liability of a municipality. Coleman, 2016 IL
    15
    No. 1-17-0859
    117952, ¶¶ 33. 8 In its analysis, the Seben court appropriately made note of these differences
    from Michigan law, which recognized the public duty rule and did not maintain local
    governmental tort immunity, in determining that the appellant’s arguments advocating for the
    “Michigan doctrine” were not persuasive. Seben, 165 Ill. at 380. This in no way suggests,
    however, that the Seben court was considering the issue of the public duty rule—or local
    governmental tort immunity, for that matter—and “reject[ing]” it. Furthermore, even if the
    case could be interpreted in that way, any “reject[ion]” of the public duty rule would have
    only lasted until 1968, when the supreme court expressly recognized the rule in Huey v.
    Town of Cicero, 
    41 Ill. 2d 361
    , 363 (1968).
    ¶ 29          Finally, plaintiffs’ counsel at oral argument also claimed that the public duty rule has
    never been applied to a “public improvement.” Again, as this argument was first raised at
    oral argument, it is not properly before this court. Moreover, as we noted with respect to
    plaintiffs’ earlier arguments, plaintiffs’ focus on whether a particular category of
    governmental service has or has not been considered with respect to the application of the
    public duty rule is not dispositive of the issue. Our supreme court has made clear that “[t]he
    public duty rule is a long-standing precept which establishes that a governmental entity and
    its employees owe no duty of care to individual members of the general public to provide
    governmental services, such as police and fire protection.” Zimmerman, 
    183 Ill. 2d at 32
    .
    Courts have applied this rule to a variety of “governmental services.” See DeSmet v. County
    of Rock Island, 
    219 Ill. 2d 497
    , 508 (2006) (noting that the rule has been applied “in various
    contexts” (citing Sims-Hearn v. Office of the Medical Examiner, 
    359 Ill. App. 3d 439
    , 443-46
    8
    The Coleman court suggested that the existence of local governmental tort immunity explained
    the lack of earlier cases discussing the public duty rule—while the immunity existed, the public duty
    rule “remained in abeyance,” since the immunity stood as an absolute bar to the enforcement of any
    civil liability arising from a breach of any duty. Coleman, 
    2016 IL 117952
    , ¶ 42.
    16
    No. 1-17-0859
    (2005), and Alexander v. Consumers Illinois Water Co., 
    358 Ill. App. 3d 774
     (2005))). For
    instance, the public duty rule has been applied to bar liability for “a general duty to the public
    to prevent *** sewer back-ups” (Alexander, 358 Ill. App. 3d at 779), for performance of
    autopsies (Sims-Hearn, 359 Ill. App. 3d at 445), for administration of a 911 emergency
    telephone system (Donovan v. Village of Ohio, 
    397 Ill. App. 3d 844
    , 850 (2010)), for failure
    to administer a vaccine (Taylor v. Bi-County Health Department, 
    2011 IL App (5th) 090475
    ,
    ¶ 36), and for failure to properly inspect a porch that subsequently collapsed (Ware v. City of
    Chicago, 
    375 Ill. App. 3d 574
    , 581 (2007)). Thus, it is apparent that the public duty rule has
    been found applicable to a wide variety of governmental services.
    ¶ 30         Nevertheless, based on our research, plaintiffs’ counsel appears to be correct in the claim
    that the public duty rule has not been considered in the context of a public improvement. The
    closest analogue would be in Alexander, where the court applied the public duty rule in the
    context of the village’s duty to prevent sewer back-ups. Alexander, 358 Ill. App. 3d at 779.
    We also note that the Seventh Circuit, applying Illinois law, has observed in dicta that there
    is no duty to provide uninterrupted water service for firefighting purposes. Remet Corp. v.
    City of Chicago, 
    509 F.3d 816
    , 820 (7th Cir. 2007). Thus, there are arguments to be made
    concerning whether the public duty rule is appropriate in considering the governmental
    entity’s duty with respect to such improvements, given the lack of case law on the issue, and
    the issue could have been further developed by both parties had plaintiffs properly raised it
    on appeal. However, we have no need to reach an answer to the question of the applicability
    of the public duty rule because our conclusion on the issue of retroactivity is dispositive. We
    turn, then, to consideration of that question.
    17
    No. 1-17-0859
    ¶ 31         We note that this appears to be a case of first impression, as we have discovered no case
    law expressly considering the retroactive applicability of Coleman. There is one case,
    involving storm water runoff and flooding, in which the public duty rule has been raised
    post-Coleman. See Salvi v. Village of Lake Zurich, 
    2016 IL App (2d) 150249
    . However, after
    noting that the defendant village had invoked the public duty rule, the court in that case
    simply noted that “our supreme court has recently abolished the public duty rule” and
    proceeded to consider the defendant’s arguments under the Tort Immunity Act without any
    discussion of whether the new law should apply retroactively. Salvi, 
    2016 IL App (2d) 150249
    , ¶ 37. Thus, from our research, we are the first court to consider whether Coleman
    should apply retroactively.
    ¶ 32         Generally, when a court issues an opinion, its decision is presumed to apply both
    retroactively and prospectively. Tosado v. Miller, 
    188 Ill. 2d 186
    , 196 (1999). However, our
    supreme court has set forth two ways for that presumption to be overcome. Aleckson v.
    Village of Round Lake Park, 
    176 Ill. 2d 82
    , 86 (1997). First, the presumption is overcome
    when a court expressly states that its decision will be applied prospectively only. Tosado, 
    188 Ill. 2d at 196-97
    . Second, “a later court may, under certain circumstances, override the
    presumption by declining to give the previous opinion retroactive effect, at least with respect
    to the parties appearing before the later court.” Aleckson, 
    176 Ill. 2d at 86
    . This authority is
    not limited to the supreme court; an appellate court has the authority to determine whether a
    previous decision should be applied prospectively with respect to a case before it. Aleckson,
    
    176 Ill. 2d at 91
    ; see also Aleckson, 
    176 Ill. 2d at 89
     (noting that the supreme court had
    previously implicitly recognized this authority when it cited an appellate court’s prospective
    application of Illinois Supreme Court and United States Supreme Court case law).
    18
    No. 1-17-0859
    ¶ 33         Our supreme court has identified three factors in determining the question of prospective
    application:
    “(1) whether the decision to be applied nonretroactively established a new principle
    of law, either by overruling clear past precedent on which litigants may have relied or
    by deciding an issue of first impression whose resolution was not clearly
    foreshadowed; (2) whether, given the purpose and history of the new rule, its
    operation will be retarded or promoted by prospective application; and (3) whether
    substantial inequitable results would be produced if the former decision is applied
    retroactively.” Tosado, 
    188 Ill. 2d at
    197 (citing Aleckson, 
    176 Ill. 2d at 92-94
    ).
    ¶ 34         In the case at bar, the Coleman court did not expressly address whether its decision would
    be prospective only. Plaintiffs claim that, because the Coleman dissent made reference to a
    case in which the court considered the retroactive application of a statutory amendment, the
    fact that the Coleman court did not specifically address the prospective application of the
    new law “buttresses the conclusion that the Coleman Court intentionally chose not to give
    prospective only effect.” We find this argument unpersuasive. First, the case was one of nine
    cases cited in a string cite to support the dissenting justice’s argument that the supreme court
    routinely engaged in an “ ‘even if’ approach to decisionmaking” by deciding dispositive
    issues first in the interests of judicial expediency. Coleman, 
    2016 IL 117952
    , ¶ 85 (Thomas,
    J., dissenting, joined by Garman, C.J., and Karmeier, J.). Additionally, the case cited by the
    dissent concerned the retroactive effect of a statute, not a court decision, which is subject to
    an entirely different analysis. See, e.g., People v. Hunter, 
    2017 IL 121306
     (discussing
    standards to be applied in determining retroactive effect of statutory amendment). Thus, we
    cannot find that the mere use of the words “prospectively” and “retroactively” in a
    19
    No. 1-17-0859
    parenthetical in this string cite in any way indicates that “certainly bells went off in the minds
    of the seven justices as to whether prospective only application of Coleman should be given.”
    The court was silent on the issue. All that this silence indicates is that the presumption of
    retroactivity has not been overcome by an express statement by the court.
    ¶ 35         Thus, we must consider whether the factors set forth in Aleckson lead us to give the law
    announced in Coleman retroactive effect. As noted, the first factor is whether the decision
    established a new principle of law, either by overruling clear past precedent on which
    litigants have relied or by deciding an issue of first impression whose resolution was not
    clearly foreshadowed. Aleckson, 176 Ill. 2d at 92. We agree with defendants that Coleman
    clearly established a new principle of law. The court was explicit in the fact that it was doing
    so and was overruling past precedent; the lead opinion contains a discussion of stare decisis
    and the dissent also focuses its analysis on that issue. See Coleman, 
    2016 IL 117952
    , ¶¶ 53-
    54 (lead opinion); Coleman, 
    2016 IL 117952
    , ¶¶ 84-96 (Thomas, J., dissenting, joined by
    Garman, C.J., and Karmeier, J.). Most clearly, all three opinions in that case refer to the
    outcome as “abandon[ing]” or “abolish[ing]” the public duty rule. See Coleman, 
    2016 IL 117952
    , ¶ 52 (lead opinion) (“the time has come to abandon the public duty rule and its
    special duty exception”); Coleman, 
    2016 IL 117952
    , ¶ 54 (“We believe that departing from
    stare decisis and abandoning the public duty rule and its special duty exception is justified
    for three reasons ***.”); Coleman, 
    2016 IL 117952
    , ¶ 61 (“we hereby abolish the public duty
    rule and its special duty exception”); Coleman, 
    2016 IL 117952
    , ¶ 64 (“We abolish the public
    duty rule and its special duty exception.”); Coleman, 
    2016 IL 117952
    , ¶ 67 (Freeman, J.,
    specially concurring, joined by Theis, J.) (“the time has come for this court to abandon the
    public duty rule and its special duty exception”); Coleman, 
    2016 IL 117952
    , ¶ 77 (“I agree
    20
    No. 1-17-0859
    that the public duty rule and its special duty exception must be abolished”); Coleman, 
    2016 IL 117952
    , ¶ 80 (Thomas, J., dissenting, joined by Garman, C.J., and Karmeier, J.) (“Today
    the court abandons these well-settled principles and abolishes the public duty rule.”);
    Coleman, 
    2016 IL 117952
    , ¶ 96 (“I find no compelling legal rationale to overrule this
    precedent and abolish the public duty rule.”) There is no way to read Coleman without
    concluding that the supreme court was making new law by overturning longstanding
    precedent.
    ¶ 36          Plaintiffs argue that Coleman did not announce a new rule because the supreme court had
    never previously applied the public duty rule to water-damage litigation and because the
    supreme court in Coleman described the jurisprudence concerning the rule to be “muddled
    and inconsistent,” meaning that the past precedent was not “clear.” We do not find these
    arguments persuasive. First, the question we must answer is not whether Coleman established
    a new principle of law in the specific context of water-damage litigation; the question is
    whether Coleman established a new principle of law, period. As noted, the Coleman court
    clearly and expressly overruled what it termed “a long-standing common-law rule”
    (Coleman, 
    2016 IL 117952
    , ¶ 42 (lead opinion)). Additionally, the fact that the supreme court
    has not spoken on a particular issue does not mean that litigants are acting in a vacuum;
    appellate court and trial court decisions can provide guidance as to the current state of the
    law even in the absence of a supreme court ruling on a particular factual scenario. For
    instance, in the case at bar, several appellate court cases, both reported and unreported, 9
    supported defendants’ claim that the public duty rule would apply to water-damage litigation.
    9
    While, of course, unreported decisions cannot be cited by the parties and have no precedential
    value, even unreported cases are publicly available and their existence can guide attorneys seeking to
    draft the best arguments to advance their clients’ positions and permits them to view analysis found
    persuasive by other courts.
    21
    No. 1-17-0859
    See, e.g., Town of Cicero v. Metropolitan Water Reclamation District of Greater Chicago,
    
    2012 IL App (1st) 112164
    , ¶ 41 n.4 (suggesting without deciding that the public duty rule
    would appear to bar claims concerning adequacy of storm management against the District);
    Alexander, 358 Ill. App. 3d at 779 (finding that the public duty rule would bar village’s
    liability for sewage system back-ups); Remet Corp., 
    509 F.3d at 820
     (in dicta, observing that
    the public duty rule meant that the city had no duty to provide uninterrupted water service for
    firefighting purposes). Additionally, in support of its motion to dismiss, the District attached
    six trial court decisions in storm management and sewer-backup cases in which it had been a
    defendant, all of which dismissed the plaintiffs’ claims against the District due to the public
    duty rule. Thus, it was eminently reasonable for defendants to rely on the public duty rule in
    challenging plaintiffs’ claims against them, and there is no basis for claiming that Coleman
    did not represent a change in law by “overruling clear past precedent on which litigants have
    relied.” Aleckson, 176 Ill. 2d at 92.
    ¶ 37         We are also unpersuaded by plaintiffs’ argument that past precedent was not “clear”
    because the primary opinion in Coleman referred to the jurisprudence concerning the public
    duty rule as “muddled and inconsistent.” First, we note that the opinion in which this
    language appears was joined by only one justice in addition to the author, meaning that it
    does not carry the weight of a majority—or even a plurality—opinion. Additionally, the
    reason the opinion characterized the jurisprudence in that way was based on the interaction
    between the public duty rule and statutory immunities. See Coleman, 
    2016 IL 117952
    , ¶¶ 55-
    57. The opinion did not indicate that the existence of the public duty rule itself was not
    22
    No. 1-17-0859
    “clear.” Accordingly, we find that, under the first factor, the Coleman court established a new
    principle of law by overruling clear past precedent on which litigants have relied. 10
    ¶ 38          The second factor we must consider is “whether, given the purpose and history of the
    new rule, its operation will be retarded or promoted by prospective application.” Tosado, 
    188 Ill. 2d at 197
    . As noted, the ultimate holding of Coleman—the abolition of the public duty
    rule—was the result of two opinions, each of which was joined by two justices. Thus, it is
    difficult to glean any overarching “purpose and history of the new rule” (Tosado, 
    188 Ill. 2d at 197
    ). The primary opinion provided three reasons for abolishing the public duty rule:
    “(1) the jurisprudence has been muddled and inconsistent in the recognition and
    application of the public duty rule and its special duty exception; (2) application of
    the public duty rule is incompatible with the legislature’s grant of limited immunity in
    cases of willful and wanton misconduct; and (3) determination of public policy is
    primarily a legislative function and the legislature’s enactment of statutory
    immunities has rendered the public duty rule obsolete.” Coleman, 
    2016 IL 117952

    By contrast, the specially concurring opinion reasoned that the public duty rule should be
    abolished because it was predicated on the same basis as the concepts underlying local
    governmental immunity and, when the constitution was amended to abolish all forms of
    10
    Plaintiffs also argue that Coleman did not establish new law because the Tort Immunity Act
    “foreshadowed the abolition” of the public duty rule. Leaving aside the fact that Coleman court
    expressly recognized that “[w]e have consistently held that the public duty rule survived the abolition
    of sovereign immunity and passage of the Tort Immunity Act” (Coleman, 
    2016 IL 117952
    , ¶ 52), we
    have no need to address this argument. The first factor asks whether the new decision established a
    new principle of law “either by overruling clear past precedent on which litigants have relied or by
    deciding an issue of first impression whose resolution was not clearly foreshadowed.” (Emphases
    added.) Aleckson, 
    176 Ill. 2d at 92
    . As noted, we have determined that the first applies—the court
    overruled clear past precedent on which litigants had relied—and so we have no need to discuss the
    second, other than to observe that it would appear almost impossible for something to be “an issue of
    first impression” when it is expressly overruling long-standing law.

    nonstatutory governmental immunity, “the judiciary’s power to apply the public duty
    doctrine ceased to exist as a means of assessing municipal tort liability.” Coleman, 
    2016 IL 117952
    , ¶ 68 (Freeman, J., specially concurring, joined by Theis, J.).
    ¶ 39          In the case at bar, defendants argue that, under the facts of the instant case, a prospective
    application of the new law set forth in Coleman would not frustrate the concerns set forth by
    the Coleman court. First, they note that the litigation history of this case renders it unique—
    the flooding occurred in 2008, and defendants first asserted the application of the public duty
    rule in 2010 and continued asserting it through the filing of a number of amended complaints,
    culminating in the amended fifth amended complaint. They finally obtained a dismissal on
    that basis on April 3, 2015, five years after they first asserted the applicability of the public
    duty rule. Had they obtained a dismissal when they first sought it in 2010, the judgment
    would have been final and appealable well prior to the supreme court’s January 22, 2016,
    decision in Coleman and we would not be considering the applicability of the public duty
    rule today. 11
    ¶ 40          Our supreme court in Aleckson found that where the court below “noted that it was
    applying [the new law] prospectively to the parties because the facts of the instant case and
    its timing vis a vis [the case establishing the new law] are so unique” that “the nonretroactive
    application was expressly limited to the facts of the case and could not have ‘retarded’ the
    future operation of” the new case. (Internal quotation marks omitted.) Aleckson, 176 Ill. 2d at
    93. Similarly, in the case at bar, the facts of the instant case and its timing vis-à-vis Coleman
    is unique; it is only through an accident of timing that Coleman was decided while this case
    11
    However, we note that a decision normally has retroactive application to any causes pending at
    the time the decision is announced, including cases on appeal in the appellate court. Heastie v.
    Roberts, 
    226 Ill. 2d 515
    , 535 (2007). Thus, if the case had been pending on appeal, plaintiffs could
    have conceivably raised the retroactivity issue at that point.
    24
    No. 1-17-0859
    was still active before the trial court. This would weigh in favor of a nonretroactive
    application of Coleman.
    ¶ 41          Defendants further argue that a nonretroactive application of Coleman in the instant case
    would also have limited impact due to the statute of limitations. Under the Tort Immunity
    Act, any civil action against a local governmental entity must be commenced within one year
    from the date that the cause of action accrued. 12 745 ILCS 10/8-101(a) (West 2016). Thus,
    any claim against a local governmental entity that is filed subsequent to our opinion must
    have accrued no earlier than May 2018. By May 2018, Coleman and its abolition of the
    public duty rule was settled law. A finding that the new law does not apply to the instant
    action would have no impact on such a lawsuit, which would be filed well after the date the
    law had changed. Thus, the only impact a nonretroactive finding could have would be upon
    cases that are currently pending before the trial or appellate courts, which would be a small
    subset of cases at most, if any.
    ¶ 42          However, we must also note the existence of Salvi, in which the Second District applied
    the new law set forth in Coleman retroactively. Salvi, 
    2016 IL App (2d) 150249
    , ¶ 37. There,
    the flooding at issue occurred in 2013 (Salvi, 
    2016 IL App (2d) 150249
    , ¶ 13), the plaintiff’s
    amended complaint was filed in 2014 (Salvi, 
    2016 IL App (2d) 150249
    , ¶ 3), and the
    defendant village raised the issue of the public duty rule in a motion to dismiss (Salvi, 
    2016 IL App (2d) 150249
    , ¶ 20). Thus, as in the case at bar, the flooding, the lawsuit, and the
    motion to dismiss based on the public duty rule all predated Coleman. 13 Despite these facts,
    12
    The exception is for actions for damages based on injury or death arising out of patient care,
    which have a two-year statute of limitations. 745 ILCS 10/8-101(b) (West 2016).
    13
    Although the opinion does not indicate the date of the defendant village’s motion to dismiss, we
    know that the motion was also filed prior to the 2016 Coleman decision because the appeal in Salvi
    was filed in 2015, as evidenced by the appeal number. Thus, Coleman would have been decided while
    the Salvi appeal was pending.
    25
    No. 1-17-0859
    the Salvi court applied the new law retroactively. Salvi, 
    2016 IL App (2d) 150249
    , ¶ 37. As
    noted, the Salvi court did not engage in a discussion of whether the law should be applied
    retroactively or prospectively; thus, we have no way of knowing what arguments were raised
    before it by the defendant village. Nevertheless, the fact remains that the Salvi court did
    expressly apply Coleman to the case before it. Salvi, 
    2016 IL App (2d) 150249
    , ¶ 37 (“[O]ur
    supreme court has recently abolished the public duty rule. [Citation.] Thus, we will proceed
    to the Tort Immunity Act.”).
    ¶ 43          The existence of Salvi is relevant to the instant discussion because a prospective
    application of Coleman to the instant case would mean that two cases with similar facts
    would be applying two different versions of the law. We are not obligated to follow the Salvi
    court’s decision if we disagree with it. See Deutsche Bank National Trust Co. v. Iordanov,
    
    2016 IL App (1st) 152656
    , ¶ 44. However, in considering the second factor of the
    retroactivity analysis, reaching a decision that would lead to conflicting case law would
    appear to feed into the “muddled and inconsistent” jurisprudence surrounding the public duty
    rule that was of concern to several justices in deciding Coleman. See Coleman, 
    2016 IL 117952
    , ¶ 54. Thus, while it would not hinder the operation of the new law, a prospective
    application of Coleman in the instant case would certainly not promote the operation of the
    new law and could even lead to an increase in the uncertainty surrounding the application of
    the rule.
    ¶ 44          The final factor to be considered is “whether substantial inequitable results would be
    produced if the former decision is applied retroactively.” Aleckson, 176 Ill. 2d at 93. In the
    case at bar, the trial court found that “[t]he retroactive application of the Coleman decision
    dramatically changes the considerations concerning the possible course of litigation of the
    26
    No. 1-17-0859
    instant case in the future.” On appeal, defendants focus on similar considerations in arguing
    that the equities favor a prospective application of the new law. Defendants claim that they
    have “endured nine years of litigation and risk exposure, waiting patiently for their time to be
    heard on the Public Duty Rule, and now must contend with the Supreme Court’s abolishment
    of the Public Duty Rule altogether,” which they argue is “not fair.” Defendants further claim
    that if Coleman applies retroactively, they will be forced to reevaluate defense and indemnity
    exposure and will endure significant litigation costs and time commitments that they
    otherwise would not have needed to endure. Certainly, if Coleman is applied to their case,
    defendants will undergo significant hardship. Any additional litigation necessarily involves
    additional time and expense. This additional expense is especially fraught when dealing with
    a governmental entity, as it is taxpayers, not a private party, who are responsible for the
    expenses. As the trial court noted:
    “The consequence to the [defendants] of the abolition of the Public Duty Rule as a
    defense is financial. Every public entity has a responsibility to its taxpayers to
    estimate budgets and to tax its citizens reasonably. Predicting legal expenses is
    difficult because the entity does not know whether litigation will be filed. Once filed,
    the entity then must budget for the potential expenses of the litigation based on a
    prediction of the legal and factual issues which might be involved. Legal issues, to be
    determined based on facts alleged in pleadings taken as true, such as the application
    of the Public Duty Rule, involve different legal expenses than the expenses necessary
    to prepare for class certification, prove the availability of immunities under the Tort
    Immunity Act, and defend against assertions of wrongdoing.”
    27
    No. 1-17-0859
    ¶ 45         In the case at bar, at the time of the flooding, at the time of the filing of the complaint,
    and at the time of dismissal of the amended fifth amended complaint, defendants were
    operating in a legal universe that included the availability of the public duty rule and
    governed their actions accordingly. Then, the supreme court overruled long-standing
    precedent—which it had expressly reaffirmed as recently as 1998—and abolished that rule,
    shifting the legal ground on which defendants stood. “Local government officials, like other
    people, are entitled to rely on [existing law] when ‘making decisions and in shaping their
    conduct.’ ” Board of Commissioners of the Wood Dale Public Library District v. County of
    Du Page, 
    103 Ill. 2d 422
    , 429 (1984) (quoting Lemon v. Kurtzman, 
    411 U.S. 192
    , 199
    (1973)). By applying the new law retroactively, defendants and their taxpayers would be
    forced to incur additional unexpected expenses in litigating this case, which could prove
    substantial, as it has been pending for 10 years to date and has yet to proceed beyond the
    pleading stage.
    ¶ 46         However, we note that these additional expenses and time commitments are not
    necessarily predicated solely on Coleman. Defendants’ argument presupposes that their
    actions were, in fact, covered by the public duty rule. Under defendants’ argument, in the
    absence of Coleman, the public duty rule would apply, marking the end of litigation.
    However, that overlooks the fact that it is not beyond dispute that the public duty rule would,
    in fact, apply. Plaintiffs likely would have appealed the trial court’s April 3, 2015, dismissal
    even in the absence of Coleman, and we would have been asked to determine whether the
    public duty rule applies to the circumstances present in the case at bar. As discussed earlier in
    our analysis, this is not a question that has been considered by our supreme court, nor is it an
    area that has a clear answer at the appellate level. If plaintiffs had prevailed in that appeal,
    28
    No. 1-17-0859
    defendants would find themselves in exactly the same position as they are now—forced to
    litigate the remainder of the case. Thus, while we recognize defendants’ understandable
    frustration at the unexpected change in the legal universe, the additional expenses that would
    be incurred by continuing to litigate the instant case should not have been entirely
    unexpected, as defendants should have been prepared for the contingency of a loss on appeal.
    ¶ 47         Plaintiffs, by contrast, argue that a prospective application of Coleman would be
    inequitable to them because they would lose the ability to have their day in court. We note
    that, unlike in the case relied on by plaintiffs, Oak Grove Jubilee Center, Inc. v. City of
    Genoa, 
    347 Ill. App. 3d 973
     (2004), this is not a case in which the plaintiff had a viable cause
    of action that would be lost by retroactive application of the new law. Here, plaintiffs had a
    cause of action that had already been dismissed, which would be revived by the retroactive
    application of the new law. In either case, though, the question is the same: applying the new
    law one way results in an active lawsuit, while applying it the other way results in the
    termination of that lawsuit. Thus, our decision has very real consequences to plaintiffs, as
    well as to defendants. We also note that, in some respects, plaintiffs are a victim of timing in
    much the same way as defendants are—if the supreme court had abolished the public duty
    rule earlier, defendants would not have been able to raise the rule in response to plaintiffs’
    complaint and the complaint would not have been dismissed on that basis. Thus, there are
    equitable arguments to be made on both sides of the equation.
    ¶ 48         In considering the three factors, there is no clear-cut answer on either side. The only clear
    answer is with respect to the first factor: Coleman made new law by abolishing the public
    duty rule. With respect to the second factor, prospective application of the new rule would
    have minimal impact on the rule’s future applicability, as the unique facts of the instant case
    29
    No. 1-17-0859
    and the Tort Immunity Act’s statute of limitations necessarily limit the scope of our holding.
    However, prospective application would result in a direct conflict with the Second District,
    given its retroactive application of Coleman in Salvi, which would further muddy the
    jurisprudence concerning the applicability of the public duty rule. Finally, with respect to the
    third factor, retroactive application of the new law would cause hardship to defendants and
    their taxpayers, as defendants relied on the long-standing law concerning the existence of the
    public duty rule and their taxpayers would be forced to absorb the additional litigation costs.
    On the other hand, such additional litigation costs should not be entirely unexpected, as
    defendants should have been prepared for the contingency of a loss on appeal even if the
    public duty rule remained in effect. By contrast, prospective application of the new law
    would result in plaintiffs being prevented from pursuing their claims against defendants.
    Thus, there are equitable considerations in favor of both parties.
    ¶ 49         As noted, when a court issues an opinion, its decision is presumed to apply both
    retroactively and prospectively, unless that presumption is overcome by either an express
    statement by the court or through the consideration of the factors set forth in Aleckson.
    Tosado, 
    188 Ill. 2d at 196-97
    . Here, there is no express statement by the supreme court and
    the Aleckson factors do not tilt in any one direction. Consequently, we cannot find that the
    presumption of retroactivity has been overcome, and therefore, the new law set forth in
    Coleman should have been applied retroactively to the instant case. Accordingly, the trial
    court erred in limiting the new law set forth in Coleman to apply only prospectively to the
    instant case, and we must reverse the trial court’s dismissal of plaintiffs’ complaint based on
    the public duty rule.

    No. 1-17-0859
    ¶ 50                                        III. Alternate Bases
    ¶ 51         Our decision concerning the public duty rule does not end our analysis, however, because
    we may affirm the trial court’s dismissal on any basis supported by the record, even if the
    trial court did not base its decision on that ground. See Raintree Homes, 
    209 Ill. 2d at 261
    (we can affirm “on any basis present in the record”); In re Marriage of Gary, 384 Ill. App. 3d
    at 987 (“we may affirm on any basis supported by the record, regardless of whether the trial
    court based its decision on the proper ground”). In the case at bar, plaintiffs alleged causes of
    action based on the Tort Immunity Act, based on the common law, and based on the Illinois
    Constitution. We consider each of these counts in turn, discussing whether they should have
    been dismissed under section 2-615 of the Code. If any of these counts should have survived
    dismissal based on section 2-615, we then consider whether they should have been dismissed
    under section 2-619.
    ¶ 52         As an initial matter, defendants make an overarching argument concerning all of
    plaintiffs’ counts that are based on negligence—they claim that plaintiffs failed to plead that
    defendants’ conduct proximately caused plaintiffs’ damages. Since this argument applies to
    many of plaintiffs’ causes of action, we address it first. “To recover damages based upon a
    defendant’s alleged negligence, a plaintiff must allege and prove that the defendant owed a
    duty to the plaintiff, that defendant breached that duty, and that the breach was the proximate
    cause of the plaintiff’s injuries.” First Springfield Bank & Trust v. Galman, 
    188 Ill. 2d 252
    ,
    256 (1999) (citing Thompson v. County of Cook, 
    154 Ill. 2d 374
    , 382 (1993)). Our supreme
    court has explained the proximate cause element as follows:
    “The proximate cause element is a factual question for the jury to decide and has
    two components: cause in fact and legal cause. [Citations.] ‘Cause in fact’ is
    31
    No. 1-17-0859
    established where there is reasonable certainty that the injury would not have
    occurred ‘but for’ the defendant’s conduct or where a defendant’s conduct was a
    ‘substantial factor’ in bringing about the harm. [Citation.] Legal cause, however, is
    essentially a question of policy, i.e., ‘How far should a defendant’s legal
    responsibility extend for conduct that did, in fact, cause the harm?’ (Internal quotation
    marks omitted.) [Citation.] Legal cause, therefore, is established only when it can be
    said that the injury was reasonably foreseeable. [Citations.]” Stanphill v. Ortberg,
    
    2018 IL 122974
    , ¶ 34.
    ¶ 53         In the case at bar, defendants claim that plaintiffs failed to allege the “cause in fact”
    component of proximate cause. In support, they point to the trial court’s dismissal of a
    negligence count against Gewalt, the engineering firm that worked with Advocate to develop
    a drainage plan in 2002; in that dismissal, the court found that plaintiffs had not alleged that
    Gewalt’s conduct after 2002 was a cause in fact in bringing about the September 2008
    flooding. However, Gewalt’s position in the litigation differs quite significantly from
    defendants’ position. Indeed, in its dismissal, the trial court specifically pointed to the fact
    that “plaintiffs alleged a host of other components of the [Prairie Creek Stormwater System]
    that contributed to the 2008 flooding, all of which existed prior to Gewalt’s post-2002
    designs on the Dempster Basin.” Plaintiffs’ allegations against defendants go far beyond the
    2002 allegations against Gewalt. They allege that plaintiffs were involved in approving the
    drainage and sewer systems as far back as the 1960s and were aware of the undersized
    drainage capacity of certain portions of the systems. They further allege that defendants
    approved of Advocate’s flawed plans for its drainage system and that defendants nevertheless
    approved them. Finally, they allege that defendants were aware of the serious design and
    32
    No. 1-17-0859
    maintenance defects with the Prairie Creek Stormwater System based on the persistent
    flooding and failed to remedy those defects or to take measures to prevent the flooding. Thus,
    we cannot agree with defendants that plaintiffs have failed to allege sufficient facts that
    defendants’ conduct was a “cause in fact” of plaintiffs’ damages. Instead, at least at this stage
    of the proceedings, plaintiffs’ allegations are sufficient to withstand a motion to dismiss. We
    turn, then, to consideration of each of plaintiffs’ causes of action individually.

    ¶ 55         With respect to the Tort Immunity Act, plaintiffs set forth causes of action for statutory
    duties pursuant to sections 3-102(a) and 3-103 of the Tort Immunity Act. Plaintiffs alleged
    that defendants breached a duty to maintain their property in a reasonably safe condition
    pursuant to section 3-102(a) and that defendants breached their duty to correct known unsafe
    conditions relating to the design of the Prairie Creek Stormwater System pursuant to section
    3-103 by not compelling Advocate to redesign its drainage plans.
    ¶ 56                                         1. Section 3-102(a)
    ¶ 57         Section 3-102(a) of the Tort Immunity Act provides:
    “Except as otherwise provided in this Article, a local public entity has the duty to
    exercise ordinary care to maintain its property in a reasonably safe condition for the
    use in the exercise of ordinary care of people whom the entity intended and permitted
    to use the property in a manner in which and at such times as it was reasonably
    foreseeable that it would be used, and shall not be liable for injury unless it is proven
    that it has actual or constructive notice of the existence of such a condition that is not
    reasonably safe in reasonably adequate time prior to an injury to have taken measures
    to remedy or protect against such condition.” 745 ILCS 10/3-102(a) (West 2012).
    33
    No. 1-17-0859
    In counts XXXVI (against the District), LVII (against Park Ridge), and LXXIV (against
    Maine Township), plaintiffs alleged that defendants breached a “statutory duty to maintain
    property” pursuant to this section. Defendants argue that these counts were properly
    dismissed because there is no such “statutory duty to maintain property.”
    ¶ 58         Defendants are correct that the Tort Immunity Act does not create any new duties. Our
    supreme court has made clear that “[t]he Tort Immunity Act grants only immunities and
    defenses; it does not create duties.” Village of Bloomingdale, 
    196 Ill. 2d at 490
    ; see also
    Barnett v. Zion Park District, 
    171 Ill. 2d 378
    , 386 (1996) (“It is settled that the Tort
    Immunity Act does not impose on a municipality any new duties.”). Instead, “the [Tort
    Immunity] Act merely codifies those duties existing at common law, to which the
    subsequently delineated immunities apply.” Barnett, 
    171 Ill. 2d at 386
    ; Monson v. City of
    Danville, 
    2018 IL 122486
    , ¶ 24 (“the courts of this state have uniformly held that section 3-
    102(a) merely codifies the common-law duty of a local public entity to maintain its property
    in a reasonably safe condition”). Thus, a court must look to the common law and other
    statutes to determine whether the defendant owes the plaintiff a duty. Barnett, 
    171 Ill. 2d at 386
    . Once the court determines that a duty exists, then it examines whether the Tort
    Immunity Act provides immunity for a breach of that duty. Village of Bloomingdale, 
    196 Ill. 2d at 490
    . “In other words, because the Act implicitly recognizes duties which already exist
    at common law, we may refer to the common law to determine the duties a local public entity
    holds. But to determine whether that entity is liable for the breach of a duty, we look to the
    Tort Immunity Act, not the common law.” Village of Bloomingdale, 
    196 Ill. 2d at 490
    .
    ¶ 59         In the case at bar, plaintiffs have styled these counts as arising under a “statutory duty to
    maintain property,” which suggests that the basis of the duty is the statute, not the common
    34
    No. 1-17-0859
    law. It is on this basis that defendants argue that the counts should be dismissed. However,
    our supreme court “has emphasized that ‘the character of the pleading should be determined
    from its content, not its label.’ ” In re Parentage of Scarlett Z.-D., 
    2015 IL 117904
    , ¶ 64
    (quoting In re Haley D., 
    2011 IL 110886
    , ¶ 67). Thus, the title of the count does not control
    over the substance of its claim. Papadakis v. Fitness 19 IL 116, LLC, 
    2018 IL App (1st) 170388
    , ¶ 32. Here, the substance of these counts of the complaint can be interpreted as
    alleging negligence based on a breach of defendants’ common-law duty to maintain their
    property in a reasonably safe condition.
    ¶ 60         However, plaintiffs have foreclosed this interpretation by making it clear in their reply
    brief that they are asserting a “separate, independent, stand-alone cause-of-action imposing
    [a] duty owing to individual citizens for [a local public entity] to maintain its property.”
    Plaintiffs further claim that “[c]odified duty is still enforceable, individual duty separate from
    common law.” Thus, plaintiffs have expressly stated that they believe that there are two
    separate, independent, duties: a common-law duty and a statutory duty. This is simply not the
    case. Even Wagner v. City of Chicago, 
    166 Ill. 2d 144
    , 150 (1995), a case relied on by
    plaintiffs, makes this clear: “ ‘Th[e] limitation on the scope of the duty in section 3-102(a) is
    in keeping with the scope of that duty as it existed at common law. The Tort Immunity Act
    creates no new duties but merely codifies those existing at common law. [Citations.] At
    common law, a municipality had a duty to maintain its property in a safe condition ***.’ ”
    (quoting West v. Kirkham, 
    147 Ill. 2d 1
    , 14 (1992)). The statutory duty is the common-law
    duty, simply published in statutory form. Plaintiffs’ insistence otherwise requires us to affirm
    the trial court’s dismissal of these counts.

    ¶ 61                                          2. Section 3-103
    ¶ 62         Similarly, counts XXXVII (against the District), LVIII (against Park Ridge), and LXXV
    (against Maine Township) were for “duty to remedy [a] dangerous plan” and allege that
    section 3-103 of the Tort Immunity Act set forth a duty for a local public entity to correct
    known unsafe conditions related to the design and/or engineering of an approved plan, which
    defendants did not do. Section 3-103(a) provides:
    “A local public entity is not liable under this Article for an injury caused by the
    adoption of a plan or design of a construction of, or an improvement to public
    property where the plan or design has been approved in advance of the construction
    or improvement by the legislative body of such entity or by some other body or
    employee exercising discretionary authority to give such approval or where such plan
    or design is prepared in conformity with standards previously so approved. The local
    public entity is liable, however, if after the execution of such plan or design it appears
    from its use that it has created a condition that it is not reasonably safe.” 745 ILCS
    10/3-103(a) (West 2012).
    ¶ 63         Again, as with section 3-102(a), section 3-103(a) “codifies [the] common-law duty of
    care in the making of public improvements.” Salvi, 
    2016 IL App (2d) 150249
    , ¶ 43; see also
    O’Brien v. City of Chicago, 
    285 Ill. App. 3d 864
    , 871 (1996) (“Sections 3-102(a) and 3-
    103(a) codify [common law] duties but do not impose any new obligations on local
    governments.”); Horrell v. City of Chicago, 
    145 Ill. App. 3d 428
    , 435 (1986) (“[T]he ‘duties’
    *** that are found in section 3-103(a) regarding the execution of a plan[ ] are derived from
    the basic common law duty articulated in section 3-102.”). At common law, a municipality
    had a duty to maintain its property in a safe condition, but this duty did not extend to creating
    36
    No. 1-17-0859
    or erecting public improvements. West v. Kirkham, 
    147 Ill. 2d 1
    , 14 (1992). Once a public
    improvement was actually constructed, however, the municipality has a duty to maintain it in
    a reasonably safe condition. West, 
    147 Ill. 2d at 14
    .
    ¶ 64         In the case at bar, again, while the substance of these counts could be interpreted as
    alleging negligence based on a breach of defendants’ common-law duty in the making of
    public improvements, plaintiffs have foreclosed this interpretation in their reply brief by
    making clear that they are alleging that section 3-103(a) “declare[s] [a] separate and
    independent dut[y]” and that this “statutory dut[y] [is a] separate and independent, individual
    dut[y] from the common law.” Accordingly, we must affirm the trial court’s dismissal of
    these counts.
    ¶ 65                                     B. Common Law Counts
    ¶ 66         Next, plaintiffs alleged several counts based on common law negligence.
    ¶ 67                                1. Dominant Estate Overburdening
    ¶ 68         Counts XXV (against the District), XLV (against Park Ridge), and LXIV (against Maine
    Township) were for “negligence: dominant estate overburdening stormwater” and alleged
    that defendants knew or should have known of the foreseeable harm of invasive flooding into
    plaintiffs’ neighborhood given the history of flooding and that defendants owed nondelegable
    duties to properly manage the storm water so as to prevent harm to plaintiffs from excess
    storm water overburdening the drainage system. On appeal, plaintiffs “abandon their
    Dominant Estate Overburdening claim” but argue that the facts alleged in these counts give
    rise to an “adjacent property owner” claim.
    ¶ 69         Generally, a landowner owes no duty to adjoining landowners for dangerous natural
    conditions present on the land, but may owe a duty if the condition is artificial or where a
    37
    No. 1-17-0859
    natural condition is aggravated by the owner’s use of the area. See Dealers Service & Supply
    Co. v. St. Louis National Stockyards Co., 
    155 Ill. App. 3d 1075
    , 1079 (1987); Choi v.
    Commonwealth Edison Co., 
    217 Ill. App. 3d 952
    , 957 (1991). Additionally, a local public
    entity bears a common law duty not to increase the natural flow of surface water onto the
    property of an adjacent landowner. Van Meter v. Darien Park District, 
    207 Ill. 2d 359
    , 369
    (2003). Defendants claim that, because they were not “adjacent landowners,” these counts
    should be dismissed. We agree.
    ¶ 70         In the case at bar, plaintiffs have not alleged that defendants are landowners, much less
    landowners adjacent to plaintiffs’ property. Plaintiffs have alleged that defendants own the
    sewers and the drains, but have not alleged that defendants own the real property under
    which those sewers and drains run. Instead, they allege that defendants were the holders of
    easements for the purpose of drainage and sewers, which ran through plaintiffs’
    neighborhood, and that it was these systems that overflowed and damaged plaintiffs’
    property. The only adjacent landowner plaintiffs identify in their complaint is Advocate.
    ¶ 71         Given the status of defendants as easement holders, not landowners, the appropriate cause
    of action would be for the overburdening of their easement. However, plaintiffs have
    expressly abandoned that claim on appeal. In the absence of that legal framework, we find no
    basis for applying “adjacent property owner” liability to defendants; plaintiffs have cited no
    authority applying such a duty without first establishing that the defendant was actually a
    landowner. Accordingly, we must affirm the dismissal of these counts.
    ¶ 72                                       2. Negligent Nuisance
    ¶ 73         Counts XXXI (against the District), LII (against Park Ridge), and LXIX (against Maine
    Township) were for “negligent nuisance” and alleged that defendants negligently caused an
    38
    No. 1-17-0859
    accumulation of water from the drainage system to invade and interfere with plaintiffs’
    property. “A private nuisance is a substantial invasion of another’s interest in the use and
    enjoyment of his or her land. The invasion must be: substantial, either intentional or
    negligent, and unreasonable.” In re Chicago Flood Litigation, 
    176 Ill. 2d at 204
    . The
    standard for determining if particular conduct constitutes a nuisance is its effect on a
    reasonable person. In re Chicago Flood Litigation, 
    176 Ill. 2d at 204
    . Our supreme court has
    explained the difference between the type of invasion that nuisance protects as compared to
    the type of invasion that trespass protects:
    “ ‘A trespass is an invasion of the interest in the exclusive possession of land, as by
    entry upon it. *** A nuisance is an interference with the interest in the private use and
    enjoyment of the land, and does not require interference with the possession.’ ” In re
    Chicago Flood Litigation, 
    176 Ill. 2d at 204
     (quoting Restatement (Second) of Torts
    § 821D cmt. d, at 101 (1979)).
    ¶ 74         In the case at bar, the complaint alleges that defendants negligently permitted an
    accumulation of storm water runoff in their drainage and sewage systems due to their
    management of the systems, which caused flood water to invade and interfere with plaintiffs’
    property on September 13, 2008. The complaint further alleges that such interference was
    substantial and unreasonable. These allegations are sufficient to state a cause of action for
    negligent nuisance so as to withstand dismissal pursuant to section 2-615.
    ¶ 75                                       3. Negligent Trespass
    ¶ 76         Counts XXXII (against the District), LIII (against Park Ridge), and LXX (against Maine
    Township) were for “negligent trespass” and alleged that, due to defendants’ failure to
    properly manage the storm water systems, water invaded plaintiffs’ property. A trespass is an
    39
    No. 1-17-0859
    invasion in the exclusive possession and physical condition of real property. Millers Mutual
    Insurance Ass’n of Illinois v. Graham Oil Co., 
    282 Ill. App. 3d 129
    , 139 (1996). “[O]ne can
    be liable under present-day trespass for causing a thing or a third person to enter the land of
    another either through a negligent act or an intentional act.” Dial v. City of O’Fallon, 
    81 Ill. 2d 548
    , 556-57 (1980).
    ¶ 77          In our prior decision concerning Advocate, we found that the complaint adequately
    alleged that Advocate could be liable for intentional trespass based on its conduct with
    respect to its drainage system. See Tzakis, 
    2015 IL App (1st) 142285-U
    , ¶ 74. We found:
    “Taken as a whole, [plaintiffs’] allegations are far from mere conclusory
    allegations. Plaintiffs identify numerous examples that suggest [Advocate] was aware
    of the flooding problem, and knowingly took inadequate measures to correct it.
    Plaintiffs’ allegations identify specific components of [Advocate’s] drainage system
    as deficient, and demonstrate multiple instances where [Advocate] had occasion to
    address the problems and failed to do so adequately. As with the examples of piling
    sand adjacent to another’s property, or erecting a dam to alter the flow of a stream,
    plaintiffs’ allegations regarding [Advocate’s] conduct are sufficient to show that
    [Advocate] acted with a high degree of certainty that its modifications to the drainage
    system would cause or fail to prevent flooding to plaintiffs’ homes.” Tzakis, 
    2015 IL App (1st) 142285-U
    , ¶ 74.
    ¶ 78          In the case at bar, plaintiffs are not alleging intentional trespass as they did against
    Advocate. 14 Thus, they are not required to allege the high degree of certainty required by an
    intentional trespass claim. However, the allegations against Advocate, which we found
    14
    We note that plaintiffs did, in fact, originally include counts for intentional trespass, but those
    counts were voluntarily dismissed and are not at issue on appeal.
    40
    No. 1-17-0859
    satisfied such a high bar, also apply in large part to defendants, as they are alleged to have
    approved all of Advocate’s plans. Thus, our prior decision is certainly instructive to the
    analysis in the instant appeal. In the case at bar, plaintiffs have alleged that there was an
    invasion in their properties due to the excess storm water runoff. Plaintiffs have further
    alleged that this invasion was caused by defendants’ negligent design and operation of their
    drainage and sewer systems. These allegations adequately set forth causes of action for
    negligent trespass against defendants so as to withstand a section 2-615 motion to dismiss. 15
    ¶ 79                                            C. Takings Clause
    ¶ 80          Finally, plaintiffs claimed that the flooding of their property was an unconstitutional
    taking that violated the Illinois Constitution. The takings clause of the Illinois Constitution
    provides that “[p]rivate property shall not be taken or damaged for public use without just
    compensation as provided by law. Such compensation shall be determined by a jury as
    provided by law.” Ill. Const. 1970, art. I, § 15. Our supreme court has defined a “taking” as
    “a physical invasion of private property or the radical interference with a private property
    owner’s use and enjoyment of the property.” Hampton v. Metropolitan Water Reclamation
    District, 
    2016 IL 119861
    , ¶ 24. The supreme court has further indicated that “a taking occurs
    when real estate is physically invaded ‘by superinduced additions of water *** so as to
    effectually destroy or impair its usefulness.’ ” Hampton, 
    2016 IL 119861
    , ¶ 24 (quoting Horn
    v. City of Chicago, 
    403 Ill. 549
    , 554 (1949)). Our supreme court has recently made explicit
    that a temporary flooding may constitute a taking. Hampton, 
    2016 IL 119861
    , ¶ 22; see also
    15
    At the end of their brief, plaintiffs include a brief paragraph concerning “equitable relief.” It is
    not apparent what argument they are attempting to make, and plaintiffs do not tie this request into any
    particular cause of action. As it has not been properly developed, we do not consider this argument.
    See Lebron, 
    237 Ill. 2d at 253
    ; Ill. S. Ct. R. 341(h)(7) (eff. May 25, 2018) (“Points not argued [in the
    appellant’s brief] are forfeited and shall not be raised in the reply brief, in oral argument, or on
    petition for rehearing.”).

    Pineschi v. Rock River Water Reclamation District, 
    346 Ill. App. 3d 719
    , 727 (2004)
    (temporary flooding caused by backup of sewer system may constitute a taking).
    ¶ 81         Our supreme court has also found instructive additional factors set forth by the United
    States Supreme Court in determining whether a temporary flooding constitutes a taking;
    “[t]hese factors include the time and duration of the flooding, whether the invasion of the
    property was intentional or whether it was a foreseeable result of an authorized government
    action, and the character of the land and the owner’s reasonable investment-backed
    expectations regarding the land’s use.” Hampton, 
    2016 IL 119861
    , ¶ 25 (citing Arkansas
    Game & Fish Comm’n v. United States, 
    568 U.S. 23
    , 38-39 (2012)).
    ¶ 82         In the case at bar, defendants claim that plaintiffs’ takings clause claims must fail because
    the water overflow was the result of Advocate’s conduct, not theirs. “To constitute a
    government taking or compensable government action, the water overflow must be the result
    of a structure or action imposed by the governmental entity ***.” Sorrells v. City of Macomb,
    
    2015 IL App (3d) 140763
    , ¶ 33. In Sorrells, the plaintiff homeowners filed suit against a
    developer who was developing adjacent property in a way that the plaintiffs alleged altered
    the natural drainage of surface waters and caused an increase of water drainage onto their
    property. Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 4. The plaintiffs also included an inverse
    condemnation claim against the defendant city, which the plaintiffs alleged had approved the
    construction and design of the developer’s plans, and to whom the streets and drainage
    system had been dedicated. Sorrells, 
    2015 IL App (3d) 140763
    , ¶¶ 17-18. The plaintiffs
    alleged that the city’s actions constituted a taking under the takings clause of the Illinois
    Constitution. Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 18.
    42
    No. 1-17-0859
    ¶ 83         On appeal, the Sorrells court affirmed the trial court’s dismissal of the counts aimed at
    the city. The court first noted that the plaintiffs alleged that the private development as a
    whole caused the allegedly unreasonable surface water drainage, not the streets that belonged
    to the city. Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 30. The court found that the complaint
    “makes clear that the water allegedly invading the plaintiffs’ property was drainage from two
    [private] storm water detention basins or other drainage basins.” Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 31. The court further found that the plaintiffs failed to allege that this unreasonable
    water draining from the development onto their land “was the intended or foreseeable result,
    in whole or in part, of the City’s actions rather than that of the development.” Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 32.
    ¶ 84         The Sorrells court also noted that condemnation cases “traditionally arise from
    government action alone; not from multiple causes that would include actions of private
    actors, as in this case where the water was from the whole development flowing into
    detention basins.” Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 33. In the case before it, the court
    found that “the alleged flooding of the plaintiffs’ land was from the overflow of drainage and
    detention basins, not from the City’s actions.” Sorrells, 
    2015 IL App (3d) 140763
    , ¶ 33.
    Consequently, the court affirmed the dismissal of the inverse condemnation claim.
    ¶ 85         In the case at bar, contrary to defendants’ claim, we cannot agree that the situation is
    analogous to that present in Sorrells. The instant case is not one in which Advocate
    developed its property, then later dedicated the streets and drainage system to defendants.
    Instead, plaintiffs allege much more hands-on involvement and ongoing responsibility from
    defendants. Additionally, plaintiffs allege a history of flooding prior to the 2008 flooding at
    issue, indicating that defendants knew of the increased risk of flooding. Finally, plaintiffs
    43
    No. 1-17-0859
    point to numerous areas in which defendants were allegedly negligent, including through the
    use of undersized drains. We note that we are not asked to determine whether plaintiffs will
    be successful in ultimately proving their takings claim—at this stage of the proceedings, a
    cause of action will not be dismissed on the pleadings unless it clearly appears that the
    plaintiff cannot prove any set of facts that will entitle it to relief. Board of Directors of
    Bloomfield Club Recreation Ass’n, 
    186 Ill. 2d at 424
    . Under the facts as alleged by plaintiffs,
    their claims under the takings clause are sufficient to satisfy this hurdle.
    ¶ 86                               D. Section 2-619 Motions to Dismiss
    ¶ 87         As explained above, we have determined that the counts concerning negligent nuisance,
    negligent trespass, and the takings clause (1) should not have been barred by the public duty
    rule and (2) are sufficient to withstand dismissal under section 2-615 of the Code. However,
    these counts were also subject to motions to dismiss pursuant to section 2-619 of the Code.
    Thus, we must consider whether they should have been dismissed under that section in order
    to determine whether there remains an alternate basis for affirming the trial court’s judgment.
    ¶ 88         On appeal, defendants claim that plaintiffs’ causes of action against them should have
    been dismissed pursuant to several sections of the Tort Immunity Act. The Tort Immunity
    Act was enacted in 1965 in response to the supreme court’s abolition of sovereign immunity.
    Monson, 
    2018 IL 122486
    , ¶ 15. It protects local public entities and their employees from
    liability arising from government operations. Monson, 
    2018 IL 122486
    , ¶ 15; 745 ILCS 10/1-
    101.1(a) (West 2006). The purpose of the Tort Immunity Act “is to prevent the dissipation of
    public funds on damage awards in tort cases.” Monson, 
    2018 IL 122486
    , ¶ 15. “Since the
    [Tort Immunity] Act was enacted in derogation of the common law, it must be strictly
    construed.” Van Meter, 
    207 Ill. 2d at 368
    ; Monson, 
    2018 IL 122486
    , ¶ 15. “Unless an
    44
    No. 1-17-0859
    immunity provision applies, municipalities are liable in tort to the same extent as private
    parties.” Van Meter, 
    207 Ill. 2d at 368-69
    ; Monson, 
    2018 IL 122486
    , ¶ 15. “Because the
    immunities afforded to governmental entities operate as an affirmative defense, those entities
    bear the burden of properly raising and proving their immunity under the [Tort Immunity]
    Act. It is only when the governmental entities have met this burden that a plaintiff’s right to
    recovery is barred.” Van Meter, 207 Ill. 2d at 370.
    ¶ 89                                   1. Sections 2-109 and 2-201
    ¶ 90         Defendants first rely on sections 2-109 and 2-201 of the Tort Immunity Act. Section 2-
    109 provides:
    “A local public entity is not liable for any injury resulting from an act or omission of
    its employee where the employee is not liable.” 745 ILCS 10/2-109 (West 2006).
    Section 2-201 provides:
    “Except as otherwise provided by Statute, a public employee serving in a position
    involving the determination of policy or the exercise of discretion is not liable for an
    injury resulting from his act or omission in determining policy when acting in the
    exercise of such discretion even though abused.” 745 ILCS 10/2-201 (West 2006).
    Our supreme court has observed that “[s]ection 2-201 extends the most significant protection
    afforded to public employees under the [Tort Immunity] Act.” Van Meter, 207 Ill. 2d at 370.
    Read together, sections 2-109 and 2-201 immunize a public entity from liability for the
    discretionary acts or omissions of its employees. Monson, 
    2018 IL 122486
    , ¶ 16.
    ¶ 91         In order for immunity to attach, a court must conduct a dual-prong inquiry. See
    Van Meter, 
    207 Ill. 2d at 373
    . First, a defendant claiming immunity under section 2-201 must
    establish that its employee held either a position involving the determination of policy or a
    45
    No. 1-17-0859
    position involving the exercise of discretion. Monson, 
    2018 IL 122486
    , ¶ 29. Additionally,
    “immunity will not attach unless the plaintiff’s injury results from an act performed or
    omitted by the employee in determining policy and in exercising discretion.” (Emphasis in
    original.) Harinek, 
    181 Ill. 2d at 341
     (1998). Thus, while under the statute, the employee’s
    position may be one which involves either determining policy or exercising discretion, in
    order for immunity to apply, the act or omission itself must be both a determination of policy
    and an exercise of discretion. Harinek, 
    181 Ill. 2d at 341
    .
    ¶ 92         Our supreme court has defined “ ‘policy decisions made by a municipality’ ” as “ ‘those
    decisions which require the municipality to balance competing interests and to make a
    judgment call as to what solution will best serve each of those interests.’ ” Harinek, 
    181 Ill. 2d at 342
     (quoting West, 
    147 Ill. 2d at 11
    ). With respect to discretionary decisions, “the
    distinction between discretionary and ministerial functions resists precise formulation, and
    *** the determination whether acts are discretionary or ministerial must be made on a case-
    by-case basis.” Snyder v. Curran Township, 
    167 Ill. 2d 466
    , 474 (1995). Our supreme court
    has defined the terms as follows:
    “[D]iscretionary acts are those which are unique to a particular public office, while
    ministerial acts are those which a person performs on a given state of facts in a
    prescribed manner, in obedience to the mandate of legal authority, and without
    reference to the official’s discretion as to the propriety of the act.” Snyder, 
    167 Ill. 2d at 474
    .
    Additionally, discretionary decisions “ ‘involve the exercise of personal deliberation and
    judgment in deciding whether to perform a particular act, or how and in what manner that act
    46
    No. 1-17-0859
    should be performed.’ ” Monson, 
    2018 IL 122486
    , ¶ 30 (quoting Wrobel v. City of Chicago,
    
    318 Ill. App. 3d 390
    , 395 (2000)).
    ¶ 93         In the case at bar, plaintiffs have alleged a number of actions and omissions that they
    claim subject defendants to liability. While defendants are undoubtedly correct that at least
    some of these actions would fall under the purview of section 2-201 immunity, we cannot
    agree with their position that they are wholly immune from liability such that dismissal is
    warranted.
    ¶ 94         For instance, one of the allegations against defendants is that the drainage and sewer
    systems represented a dangerous condition and that defendants failed to correct that condition
    by, inter alia, not pumping down the retention basins prior to the September 2008 storm. Our
    supreme court has recognized that decisions involving repairs to public property can be a
    discretionary matter subject to immunity under section 2-201. Monson,

    ¶ 33. However, “a public entity claiming immunity for an alleged failure to repair a defective
    condition must present sufficient evidence that it made a conscious decision not to perform
    the repair. The failure to do so is fatal to the claim.” Monson, 
    2018 IL 122486
    , ¶ 33. Here,
    there has been no showing that it was a conscious decision not to pump down the basins prior
    to the storm. Accordingly, that decision would not be subject to section 2-201 immunity.
    ¶ 95         As noted, “[s]ection 2-201 extends the most significant protection afforded to public
    employees under the [Tort Immunity] Act.” Van Meter, 
    207 Ill. 2d at 370
    . Thus, we must be
    especially careful when speaking broadly about sweeping all of defendants’ alleged conduct
    with the same brush. In the case at bar, plaintiffs have alleged acts and omissions by
    defendants that would not be subject to section 2-201 immunity. Accordingly, it is
    inappropriate to wholly dismiss the counts aimed at defendants on the basis of that immunity
    47
    No. 1-17-0859
    and we cannot find that section 2-201 immunity serves as an alternate basis for dismissal of
    plaintiffs’ complaint at this time.
    ¶ 96                                             2. Section 2-105
    ¶ 97           Defendants next claim that they are immune under section 2-105 of the Tort Immunity
    Act, which provides:
    “A local public entity is not liable for injury caused by its failure to make an
    inspection, or by reason of making an inadequate or negligent inspection, of any
    property, other than its own, to determine whether the property complies with or
    violates any enactment or contains or constitutes a hazard to health or safety.” 745
    ILCS 10/2-105 (West 2006).
    ¶ 98           In the case at bar, plaintiffs allege that all three defendants own and operate various
    portions of the drainage and sewer systems at issue. We agree with defendants that, under
    section 2-105, each defendant is immune from liability for a failure to inspect any property
    that is not determined to belong to that defendant. However, at this point in the litigation, we
    must take the allegations of the complaint as true (Morr-Fitz, Inc., 
    231 Ill. 2d at 488
    ), and
    therefore must accept plaintiffs’ allegations that defendants own the property at issue.
    Accordingly, section 2-105 does not provide an alternate basis for dismissal of the complaint.
    ¶ 99                                             3. Section 2-104
    ¶ 100          Next, defendants Park Ridge and the District claim that they are immune under section 2-
    104 of the Tort Immunity Act. 16 Section 2-104 provides:
    16
    While the three defendants filed a joint brief on appeal and do not specify which defendants are
    making this argument, the motion to dismiss filed by Maine Township before the trial court does not
    list section 2-104 as a basis for dismissal. Accordingly, we consider this section with respect to Park
    Ridge and the District alone.
    48
    No. 1-17-0859
    “A local public entity is not liable for an injury caused by the issuance, denial,
    suspension or revocation of, or by the failure or refusal to issue, deny, suspend or
    revoke, any permit, license, certificate, approval, order or similar authorization where
    the entity or its employee is authorized by enactment to determine whether or not
    such authorization should be issued, denied, suspended or revoked.” 745 ILCS 10/2-
    104 (West 2006).
    ¶ 101          In the case at bar, plaintiffs allege that these defendants should be held liable for
    plaintiffs’ flooding damage in part because they approved Advocate’s plans for its drainage
    system. We agree with defendants that, to the extent that plaintiffs claim that their injury was
    caused by defendants’ approval of Advocate’s plans, the plain language of section 2-104
    immunizes defendants from liability for such claims. However, such immunity is limited to
    injuries caused by the approval itself—where defendants’ actual actions or omissions are at
    issue, section 2-104 immunity would not apply. See Salvi, 
    2016 IL App (2d) 150249
    , ¶ 46
    (denying section 2-104 immunity where the village’s actions in reconstructing a pond and
    developing a parcel were at issue, as opposed to its issuance of permits or approvals).
    Therefore, dismissal at this time is not warranted.
    ¶ 102                                            4. Section 3-110
    ¶ 103          Finally, defendants Maine Township and Park Ridge claim that they are immune from
    liability under section 3-110 of the Tort Immunity Act. 17 Section 3-110 provides:
    “Neither a local public entity nor a public employee is liable for any injury occurring
    on, in, or adjacent to any waterway, lake, pond, river or stream not owned,
    17
    The District’s motion to dismiss did not raise section 3-110 as a basis for dismissal, and
    accordingly, we consider the section with respect to Maine Township and Park Ridge alone.
    49
    No. 1-17-0859
    supervised, maintained, operated, managed or controlled by the local public entity.”
    745 ILCS 10/3-110 (West 2006).
    ¶ 104         In the case at bar, these defendants argue that all injury resulted from flooding that came
    from a waterway—the Prairie Creek Stormwater System—and that plaintiffs did not allege
    facts supporting their claim that Maine Township or Park Ridge owned, supervised,
    maintained, operated, managed, or controlled any component of that system. We do not find
    this argument persuasive. First, the Prairie Creek Stormwater System as a whole would not
    be considered a “waterway” for purposes of section 3-110. As defined in the complaint, the
    Prairie Creek Stormwater System is a system of public improvements consisting of (1) open
    drains, (2) enclosed pipes, (3) retention basins, and (4) tributary storm water sewers that run
    under the streets. While the retention basins would arguably fall under section 3-110’s
    definition of a “pond,” the remainder of the system would certainly not be considered a
    “waterway.” See Black’s Law Dictionary 1623 (8th ed. 1999) (defining “waterway” in the
    same way as “watercourse”: “A body of water, [usually] of natural origin, flowing in a
    reasonably definite channel with bed and banks. The term includes not just rivers and creeks,
    but also springs, lakes, and marshes in which such flowing streams originate or through
    which they flow.”); American Heritage Dictionary 1367 (2d College ed. 1985) (defining
    “waterway” as “[a] navigable body of water, such as a river, channel, or canal”); Oxford
    Living Dictionaries, https://en.oxforddictionaries.com/definition/waterway (last visited May
    10, 2019) [https://perma.cc/NU2H-LWKW] (defining “waterway” as “[a] river, canal, or
    other route for travel by water”). Thus, section 3-110 immunity would not apply.
    ¶ 105         Furthermore, plaintiffs’ complaint alleges that both defendants bore responsibility for the
    portions of the system falling within their jurisdictions. While defendants point to a comment
    50
    No. 1-17-0859
    by plaintiffs’ counsel that they claim constitutes an admission that Maine Township did not
    “own” the system, even if that comment is read in the way defendants wish, section 3-110
    limits immunity not only for owners but also for those who “supervise[ ], maintain[ ],
    operate[ ], manage[ ] or control[ ]” such waterways. 745 ILCS 10/3-110 (West 2006). As
    noted, the complaint alleges that defendants bore such responsibility over the system. In the
    case at bar, then, section 3-110 does not serve as an alternate basis for dismissal of plaintiffs’
    complaint.
    ¶ 106                                          CONCLUSION
    ¶ 107         For the reasons set forth above, the trial court erred in applying Coleman prospectively
    and, accordingly, erroneously granted defendants’ section 2-615 motion to dismiss on the
    basis of the public duty rule. However, the counts based on violations of the Tort Immunity
    Act and for adjacent property owner liability were nevertheless properly dismissed under
    section 2-615 because plaintiffs failed to state causes of action with respect to each of those
    counts. The counts based on negligent nuisance, negligent trespass, and the takings clause
    were sufficient to withstand dismissal under section 2-615, and most of defendants’ claims of
    immunity under the Tort Immunity Act do not provide an alternate basis for dismissal of
    those counts under section 2-619. Accordingly, we reverse the trial court’s dismissal of
    plaintiffs’ complaint with respect to defendants Park Ridge, Maine Township, and the
    District on those counts.
