    ______________________________________________________________________________
    JUSTICE O'MALLEY delivered the opinion of the court:
    Plaintiffs, the Village of Bensenville, and Bensenville residents Roberta Baird, William
    Baird, Arlene Benson, Bernardo Flores, Gail Flores, Nelson Marrero, and Robert Rackrow
    (Residents), appeal the orders of the circuit court of Du Page County dismissing counts I through IV
    of their five-count second amended complaint against defendant, the City of Chicago (Chicago), and
    dissolving a preliminary injunction barring Chicago from demolishing structures in Bensenville
    pursuant to its plan to expand O'Hare International Airport (O'Hare). We affirm in part, reverse in
    part, and remand for further proceedings.
    BACKGROUND
    No. 2--08--0769
    The following facts set the backdrop of this matter. We will provide additional facts as
    needed in our discussion of the issues.
    In 2001, Chicago, as owner and operator of O'Hare, proposed the O'Hare Modernization
    Program (OMP), which would reconfigure and expand O'Hare's facilities, with the purpose of
    streamlining air traffic and reducing flight delays. The primary measure in the OMP is the
    installation of parallel runways to replace O'Hare's existing body of intersecting runways, to which
    the Federal Aviation Administration (FAA) has attributed much of O'Hare's inefficiency. The OMP
    outlines a two-phased "Master Plan" for expansion. Phase 1 calls for the expansion of an existing
    runway, the reconfiguration of taxiways and a concourse, and the construction of two new runways,
    a new western satellite terminal, and an underground automated transit system or "people mover"
    connecting the new satellite terminal with the main terminal.1 Phase 2 envisions the expansion of
    another existing runway and the construction of two additional new runways as well as a "world
    gateway terminal."
    In 2003, the Illinois General Assembly enacted the O'Hare Modernization Act (Act) (620
    ILCS 65/1 et seq. (West 2006)). In its prefatory findings, the legislature determined that "O'Hare
    cannot efficiently perform its role in the State and national air transportation systems unless it is
    reconfigured with multiple parallel runways." 620 ILCS 65/5(a)(2) (West 2006). The legislature
    found it "essential" that the OMP "be completed efficiently and without unnecessary delay" and that
    "acquisition of property as required for the [OMP] be completed as expeditiously as practicable."
    620 ILCS 65/5(a)(6), (a)(7) (West 2006). To carry out Chicago's expansion efforts, it is empowered
    1
    An FAA document in the record states that construction of the western terminal is projected
    to be "initiated" during Phase l but is "independent of other Phase 1 components."
    -2-
    No. 2--08--0769
    by the Act to "acquire by gift, grant, lease, purchase, [or] condemnation ***, or otherwise any right,
    title, or interest in any private property," including property outside Chicago's boundaries. 620 ILCS
    65/15 (West 2006). The Act allows acquisition of property "that [Chicago] reasonably determines
    will be necessary for future use, regardless of whether final regulatory or funding decisions have
    been made." (Emphasis added.) 620 ILCS 65/15 (West 2006). The Act also contains a broad
    preemption clause providing: "Airport property shall not be subject to the laws of any unit of local
    government except as provided by ordinance of [Chicago]." 620 ILCS 65/25 (West 2006).
    The OMP identifies 615 parcels in Bensenville that Chicago believes it must acquire in order
    to complete the expansion project at O'Hare. These parcels, situated off the southwest corner of
    O'Hare, are collectively identified by the OMP as the "Southwest Acquisition Area" (Acquisition
    Area). The properties in the Acquisition Area are variously improved with residential, commercial,
    and industrial structures. Plaintiffs all own properties in the Acquisition Area. Chicago has initiated
    eminent domain proceedings against those properties. This suit, City of Chicago v. Forest Preserve
    District of Du Page County, No. 06--ED--111, is pending before Judge Stephen J. Culliton in the
    circuit court of Du Page County.2 As for the remaining properties in the Acquisition Area, it appears
    that Chicago has acquired the great majority of them, though precisely how many is unclear. It also
    appears that some were acquired through eminent domain proceedings and some through voluntary
    sales, but again the respective numbers are not clear from the record.
    2
    The record does not clearly show whether all of the Residents have properties involved in
    the Culliton proceeding or, moreover, whether any properties owned by Bensenville itself are
    involved. The parties appear to assume that the Residents and Bensenville all have properties at
    stake in the Culliton proceeding, and we proceed on that assumption.

    No. 2--08--0769
    In 2006 and 2007, Chicago drafted plans for demolishing structures it acquired or planned
    to acquire in the Acquisition Area. Chicago also developed a "Demolition Health and Safety Plan,"
    which described Chicago's measures for insuring that the demolition would proceed without risk to
    public safety.
    On June 28, 2007, plaintiffs initiated the present action by filing a two-count complaint
    against Chicago. Count I sought a declaratory judgment that Chicago's demolition plans must
    comply with Bensenville's recently enacted Demolition Ordinance, which provides detailed permit
    requirements for all demolition within the Bensenville village limits. Bensenville Village Code
    §9--6a--2(F) (eff. February 27, 2008). The Demolition Ordinance provides that any application for
    a demolition permit must include plans for replacing the structures planned for demolition.
    Bensenville Village Code §9--6a--2(B) (eff. February 27, 2008). The Demolition Ordinance contains
    a specific exception for Chicago's demolition of structures in the Acquisition Area, provided Chicago
    demonstrates that the demolition is "necessary" to accomplish the OMP. Bensenville Village Code
    §9--6a--2(C)(2) (eff. February 27, 2008).
    Count II of plaintiffs' complaint alleged that demolition under the plans proposed by Chicago
    would constitute a public nuisance, as it would "expose *** Bensenville residents and their families
    to toxic or hazardous substances and chemicals released by the demolition."
    Plaintiffs simultaneously moved for an injunction barring Chicago from demolishing any
    properties in the Acquisition Area during the pendency of the lawsuit. Plaintiffs alleged that Chicago
    planned to demolish the properties without having quantified all potentially harmful substances in
    the structures and soils of the properties or designed appropriate measures to control the release of
    such substances into the air or ground water during demolition. Plaintiffs attached to their motion
    -4-
    No. 2--08--0769
    sworn declarations from Kenneth Mundt and Mark Travers, both employees of Environ, a firm
    retained by Bensenville to assess the health risks posed by demolition of structures in the Acquisition
    Area.
    Mundt, an epidemiologist, averred in his declaration that the demolition as planned by
    Chicago would "create[] a significant potential endangerment to the health and safety of Bensenville
    residents and their families." Mundt stated that he had reviewed Chicago's plan for controlling
    emissions of harmful substances during demolition and found it inadequate to protect either
    demolition workers or Bensenville residents who live in the Acquisition Area or in the vicinity.
    Mundt identified hazardous substances that are likely present in the structures or soils in the
    Acquisition Area:
    "Based on the mix of industrial, commercial, and residential structures in the
    Acquisition Area (as well as the historical uses of the area), it is highly likely that the
    following hazardous or toxic substances are present in the structures to be demolished (or in
    the surrounding soils and groundwater):        lead, mercury, pesticides, insecticides and
    herbicides, polychlorinated biphenyls (PCBs), chemical wood preservatives such as chromate
    copper arsenate, pentachlorophenols, creosote, paint and solvent compounds containing
    volatile organic compounds, petroleum wastes containing benzene and PAHs (polycyclic
    aromatic hydrocarbons), pathogenic mold spores, and septic system wastes containing
    bacterial and viral pathogens."
    Mundt stated that these substances can, depending on their concentrations, cause "severe adverse
    health effects including lung diseases, central nervous system damage, learning disabilities in
    children, cancer, birth defects, liver damage, and damage to reproductive systems." Mundt cautioned
    -5-
    No. 2--08--0769
    that a full list of the hazardous substances in the Acquisition Area was not possible until the area was
    comprehensively investigated and tested.
    Mundt described a three-step process that he recommended be completed before demolition.
    The first step is a comprehensive area-wide field investigation and sampling. This step involves
    identifying "the locations, types, and quantities of hazardous or toxic materials in and around the
    structures to be demolished." Mundt contrasted this approach with Chicago's proposed method of
    testing, which he criticized as "start-stop" because Chicago intended to test and demolish piecemeal
    rather than test the site in full before commencing demolition. Mundt opined that Chicago's method
    was inadequate because it failed to consider the additive or cumulative effects of releases from
    multiple parcels or structures.
    The second step, according to Mundt, is to develop a baseline risk assessment, which
    involves using data from the field-testing stage to calculate the degree to which demolition will
    expose to hazardous substances demolition workers and residents living in the Acquisition Area or
    its vicinity. If the exposure is likely to exceed "accepted levels of public health protection," then
    strict controls are necessary to reduce the exposure to acceptable levels. Mundt averred that, since
    Chicago did not perform proper field testing, it necessarily could not have performed a proper risk
    assessment.
    The third step, explained Mundt, is to establish "sufficiently strict control measures" to insure
    that levels of exposure do not exceed "accepted levels of public health protection." Mundt opined
    that, since Chicago did not perform proper field testing or prepare a proper risk assessment, Chicago
    has no basis for claiming that its demolition proposal will adequately protect public health.

    No. 2--08--0769
    In his declaration, Travers, a geologist, noted that Bensenville's Demolition Ordinance
    requires an applicant for a demolition permit to submit plans for (in his words):                (1) "a
    comprehensive investigation of the location, type, and quantity of hazardous chemical[s] and
    materials in the entire area to be demolished"; and (2) demolition controls that "minimiz[e] the
    public health risk from release of those hazardous chemicals during demolition." Travers opined that
    the Demolition Ordinance "is a carefully developed and organized set of requirements designed to
    protect the public health and safety of Bensenville residents and their families from exposure to
    hazardous or toxic chemicals and materials that may be released during demolition activities."
    Travers averred that Chicago's compliance with the Demolition Ordinance was "essential" for public
    protection.
    At a July 2007 hearing on the motion for injunctive relief, the trial court held that count I did
    not provide a basis for an injunction because plaintiffs were not likely to succeed on the merits. The
    court reasoned that the Demolition Ordinance was preempted by section 25 of the Act, which
    provides that "[a]irport property shall not be subject to the laws of any unit of local government
    except as provided by ordinance of [Chicago]." 620 ILCS 65/25 (West 2006). The court did,
    however, find a basis for injunctive relief in count II, alleging a public nuisance. The court entered
    a preliminary injunction:
    "against [Chicago] on any further demolition of any kind or nature within [the Acquisition
    Area] until an area-wide field investigation and sampling program is done identifying any
    location, type and quantities of hazardous or toxic materials in or around the structures to be
    demolished in the demolition area."
    As for the duration of the injunction, the court said:
    -7-
    No. 2--08--0769
    "Once that area-wide field investigation and sampling program has been completed, then we
    will hold an evidentiary hearing in regard to the findings that have been made, any expert
    testimony that either Bensenville or [Chicago] may wish to put forth in open court, and any
    other testimony that may be relevant in regard to same for this Court to make a determination
    whether [the] preliminary injunction [should continue] *** or whether [it] [should] terminate
    at that point with there being sufficient safeguards and protection for the public health of
    those residents of Bensenville and the surrounding areas to satisfy this Court."
    The court put the matter over for status.
    In October 2007, plaintiffs filed a four-count amended complaint. Count I alleged common-
    law fraud, in that Chicago knowingly made to property owners in the Acquisition Area false
    statements that all of their parcels are necessary for completion of the OMP. Plaintiffs alleged,
    without elaboration, that, "[w]ith the exception of one parcel of property owned by [Bensenville],"
    none of the properties in the Acquisition Area are needed for Phase 1 of the OMP. Plaintiffs alleged
    that only a portion of Phase 1 received the requisite approval from the "Majority-In-Interest Airlines"
    (MII Airlines) at O'Hare. Plaintiffs asserted that only Phase 2 could possibly warrant acquisition of
    plaintiffs' properties in the Acquisition Area but that Phase 2 was unlikely ever to be completed,
    because the MII Airlines probably would not approve Phase 2 given its projected cost. Plaintiffs
    asserted that Chicago knows that completion of Phase 2 is unlikely and that Phase 2 "is little more
    than a public relations creation by Chicago to provide a false justification for acquiring and
    destroying the residential and commercial properties in the Acquisition Area."
    Count II of the complaint pleaded constructive fraud based on the same false statements
    alleged in count I. Count III reasserted the first complaint's claim that the Demolition Ordinance
    -8-
    No. 2--08--0769
    governs the demolition of properties in the Acquisition Area. Count IV realleged that the demolition
    would constitute a public nuisance if it proceeded under the plans proposed by Chicago.
    Chicago moved to dismiss counts I through III, pursuant to section 2--615 of the Code of
    Civil Procedure (Code) (735 ILCS 5/2--615 (West 2006)). The trial court granted the motion as to
    counts I and II but not count III. The court dismissed count I on the grounds that: (1) Chicago's
    statements as to Acquisition Area properties' necessity for the OMP were legal opinions based on
    statutory or constitutional criteria for condemnation and therefore were not proper subjects of a fraud
    action, pursuant to Stern v. Norwest Mortgage, Inc., 
    284 Ill. App. 3d 506
     (1996); (2) Chicago's
    statements that it would use the properties for either Phase 1 or Phase 2 were statements of future
    intent and therefore not actionable as fraud (see People ex rel. Peters v. Murphy-Knight, 
    248 Ill. App. 3d 382
    , 387 (1993) ("[s]tatements regarding future events are considered opinions, not statements
    of fact," and therefore cannot be fraudulent)); (3) plaintiffs' alleged damages were "speculative at
    best" because plaintiffs did not allege that Chicago had no intent to use the properties for Phase 1
    or Phase 2; and (4) relatedly, the lack of final approval for Phase 1 or Phase 2 did not vitiate
    Chicago's ability to acquire the properties, because the Act allows acquisition of properties that
    Chicago "reasonably determines will be necessary for future use, regardless of whether final
    regulatory or funding decisions have been made" (emphasis added) (620 ILCS 65/15 (West 2006)).
    The court dismissed count II because plaintiffs set forth no facts that would prove "the
    existence of a fiduciary relationship between Chicago and Bensenville." In denying the motion to
    dismiss with respect to count III, the court reasoned that Chicago's sole contention was that the
    ordinance was preempted by the Act, an affirmative matter not properly claimed in a section 2--615
    motion. The court noted that the dismissal of counts I and II was without prejudice.
    -9-
    No. 2--08--0769
    In November 2007, Chicago filed with the court a status report regarding its plans for
    surveying and sampling the Acquisition Area as previously ordered by the court. Chicago informed
    the court that it had retained the firm of Conestoga-Rovers and Associates (CRA) to conduct the
    investigation. The court set July 7, 2008, for an evidentiary hearing on whether the preliminary
    injunction should continue.
    On March 11, 2008, plaintiffs filed a five-count, second amended complaint. Count I of the
    second amended complaint was entitled "Declaration and Injunctive Relief as to the Constitutionality
    of the O'Hare Modernization Act." In their foundational allegations, plaintiffs averred that Chicago
    "has acquired--either through eminent domain or threat of eminent domain--several hundred ***
    residential and commercial properties in Bensenville in the Acquisition Area." Plaintiffs further
    alleged that Chicago is currently seeking to acquire through eminent domain plaintiffs' own
    properties.
    Plaintiffs pleaded for two declarations. First, plaintiffs sought a declaration that the Act does
    not override the requirement of article I, section 15, of the Illinois Constitution, the takings clause,
    that "the courts *** decide after an evidentiary hearing whether any particular parcel is necessary"
    for a public purpose. See Ill. Const. 1970, art. I, §15 ("Private property shall not be taken *** for
    public use without just compensation as provided by law"); People ex rel. Director of Finance v.
    Young Women's Christian Ass'n, 
    86 Ill. 2d 219
    , 232 (1981) (YWCA) (the takings clause of the
    Illinois Constitution " 'is a restraint and limitation placed upon the exercise of [the condemnation
    power] as against the right of the private citizen except in those cases where public necessity requires
    the taking of private property for public use' "), quoting Department of Public Works & Buildings
    v. Ryan, 
    357 Ill. 150
    , 154 (1934).
    -10-
    No. 2--08--0769
    Second, plaintiffs sought a declaration that Chicago did not satisfy the constitutional
    requirement of necessity in "taking" properties in the Acquisition Area. In support, plaintiffs alleged
    that only a portion of the OMP's Phase 1, i.e., the "Phase 1 Airfield Project," was currently in
    progress. Plaintiffs further alleged that, "[w]ith the exception of a small number of properties on the
    north end of the so-called 'Acquisition Area,' Chicago has no need for any properties in Bensenville
    for [Phase 1]--or the Phase 1 Airfield Project." With respect to Phase 2, plaintiffs averred that "there
    is no certainty that [Phase 2] will be constructed within any reasonable period of time as required
    by the necessity limitations of the Illinois Constitution." Plaintiffs alleged that, "despite this lack of
    necessity for property in Bensenville, Chicago has acquired--through eminent domain proceedings
    or the threat of eminent domain--several hundred residential and commercial properties in
    Bensenville on the false assertion that these properties are necessary" for the OMP.
    In addition to declaratory relief, plaintiffs asked that Chicago be ordered to restore "to their
    prior state and condition" the properties it "acquired" from the Acquisition Area. Plaintiffs also
    asked that Chicago be enjoined from "further acquisitions" of property in Bensenville "under any
    claim that the properties are necessary" for the OMP, until Chicago proves its compliance with the
    constitutional necessity requirement.
    Count II pleaded common-law fraud. Plaintiffs made the following core allegations:
    "(A) False statement of material fact. Here the false statements of material fact are
    Chicago's false factual allegations made to meet the necessity requirement of the Illinois
    Constitution.
    i. That all of the properties in the Acquisition Area are needed for [Phase 1]
    -11-
    No. 2--08--0769
    when at most only a few parcels are needed; the vast majority of Plaintiffs' properties
    are not needed; and the vast majority of parcels in the Acquisition Area are not
    needed for the 'Phase 1 Airfield Project' or any portion of [Phase 1].
    ii. That all of the properties in [the] Acquisition Area are needed for thefuture
    [Phase 2] and that the necessity requirement of the Illinois Constitution is met
    because [Phase 2] will be constructed by 2014. This statement of future need is false
    because Chicago has no basis in fact to assert that [Phase 2] will be constructed by
    2014 or any future date, if ever.
    (B) Defendant's knowledge that the statement is false. Chicago knows that its
    factual assertions as set forth in paragraph (A) are false.
    (C) Defendant's intent that the false statement induce the Plaintiffs to act.
    *** Here Chicago knew and intended its false factual statements as to necessity would cause
    many property owners to sell their homes and businesses under threat of eminent domain.
    The false statements by Chicago as to the facts--i.e., that Chicago had demonstrated a factual
    basis of constitutional necessity in accordance with the Illinois Constitution's limitations on
    the power of eminent domain--were made to property owners who sold their homes and
    businesses under threat of eminent domain and to the DuPage [sic] County Circuit Court
    which unwittingly accepted these assertions as the truth.
    (D) Plaintiffs' reliance on the truth of the false statement. Here many--indeed
    hundreds of property owners--sold their homes to Chicago under threat of eminent domain
    in reliance on the truth of Chicago's false statements as to necessity to take their properties.
    In turn by selling their homes in response to these false statements as to necessity, these
    -12-
    No. 2--08--0769
    property owners (with the assistance and encouragement of Chicago) left the neighborhood
    a deserted wasteland."
    Plaintiffs alleged as injuries that: (1) parts of the Acquisition Area have been turned into "a virtual
    wasteland" in that the acquired properties are uninhabited, and plaintiffs have suffered a resulting
    "[l]ack of community"; and (2) the loss of neighboring properties has diminished plaintiffs' property
    values and the reduction in the tax base has led to higher taxes.
    Count III alleged unjust enrichment. Plaintiffs pleaded that "Chicago has improperly and
    unjustly obtained and continue[s] to retain the use of the properties in the Acquisition Area by
    violating the necessity limits of the Illinois Constitution and by false statements as to necessity."
    Count IV realleged the claim from the prior complaints that demolition in the Acquisition
    Area was governed by the Demolition Ordinance. Count V realleged the public nuisance claim from
    the prior complaints.
    Plaintiffs also filed a motion for injunctive relief under counts I through III of the second
    amended complaint. Also, under count V, plaintiffs sought the same injunctive relief that was
    currently in place. Plaintiffs did so to preserve the status quo in the event the court dissolved the
    injunction at the July 2008 evidentiary hearing.
    On April 11, 2008, Chicago moved to dismiss counts I and IV, pursuant to section 2--619
    of the Code (735 ILCS 5/2--619 (West 2006)), and counts II and III pursuant to section 2--615 of the
    Code. Plaintiffs filed a response to the motion. To particularize their allegations of fraud in count
    II, plaintiffs attached an affidavit from Joseph Del Balzo, former acting administrator of the FAA.
    Del Balzo averred that he reviewed documents relating to the OMP and found that Phase 1 requires
    -13-
    No. 2--08--0769
    only 33 properties in the Acquisition Area, not 615 properties as Chicago claimed. Del Balzo further
    determined that none of the documents indicates an estimated completion date for Phase 2.
    On June 26, 2008, the trial court dismissed counts I and IV under section 2--619 and counts
    II and III under section 2--615. The court first addressed the grounds for dismissing counts I and IV.
    The court construed count I as alleging "that Chicago's acquisition of properties in Bensenville is
    unconstitutional because those properties are not necessary, as required by the Illinois Constitution."
    The court proceeded from the premise that, "[if] property is not necessary for [a] public project, there
    is no constitutional authority to take the property--despite what the Legislature has asserted in the
    authorizing statute." The court distinguished between properties owned by plaintiffs, which Chicago
    is presently attempting to acquire in the proceedings before Judge Culliton, and all other properties
    in the Acquisition Area, which the court noted were "owned by individuals who contracted with
    Chicago for the sale of those properties."3
    The trial court held that plaintiffs' claims respecting their own properties were barred on the
    ground that there is "another action pending between the same parties for the same cause" (735 ILCS
    5/2--619(a)(3) (West 2006)), namely, the eminent domain action before Judge Culliton. The trial
    court found that the proceedings before Judge Culliton could provide plaintiffs "complete relief"
    with respect to their own properties. As for the remaining properties, the trial court held that
    plaintiffs lacked standing to challenge their acquisition by Chicago. The court noted plaintiffs'
    reliance on two cases, People ex rel. Klaeren v. Village of Lisle, 
    202 Ill. 2d 164
     (2002), and Yusuf
    3
    This is contrary to plaintiffs' allegation, and the assumptions of the appellate briefs, that
    some of these properties were acquired through eminent domain proceedings.
    -14-
    No. 2--08--0769
    v. Village of Villa Park, 
    120 Ill. App. 3d 533
     (1983), to establish standing, but the court found that
    plaintiffs alleged injuries unlike those in Yusuf or Klaeren.4
    As for count IV, the court held that, in light of section 25 of the Act (620 ILCS 65/25 (West
    2006)) ("Airport property shall not be subject to the laws of any unit of local government except as
    provided by ordinance of [Chicago]"), it is "clear *** that any property acquired by the City of
    Chicago for the purposes of OMP is not subject to the Bensenville Demolition Ordinance."
    The court then turned to counts II and III, which alleged fraud and unjust enrichment,
    respectively. On count II, the court reasoned:
    "This court reaches the same conclusion it reached the last time plaintiffs presented
    a fraud claim--the alleged damages are speculative at best. The acquired properties are to be
    used for the benefit of the State of Illinois, and there is no evidence that Chicago plans to use
    them for anything else.       Assurance as to future events is generally not considered
    misrepresentation of fact. [Citation.] As such, Chicago's stated intention to use the acquired
    properties for the [OMP] cannot be considered fraud. In addition, a legal position, even if
    alleged to be wrong, is not fraud. [Citation.] Therefore, Chicago's legal position that it has
    discretion (granted by the Illinois legislature) to determine what parcels of land it requires
    for completion of the [OMP] cannot be considered a fraudulent statement."
    On count III, the court said:
    4
    Plaintiffs did not argue, and the trial court did not on its own consider, what standing
    Bensenville might have as the municipality in whose territorial boundaries another government body
    seeks to acquire property by eminent domain.

    The court also denied, as moot, plaintiffs' motion for injunctive relief under counts I through

    the denial of their motion. This court denied the petition.
    On July 7-10, 2008, the trial court held an evidentiary hearing on whether its injunction
    should continue against demolition of the properties in the Acquisition Area. Chicago presented its
    case first, and its first witness was Fred Blickle, an environmental engineer with CRA and an expert
    in developing and evaluating plans for the decommissioning and demolition of residential,
    commercial, or industrial structures. Blickle explained that "decommissioning" is the process of
    removing potentially hazardous material from a structure before demolishing it. Blickle testified that
    CRA was hired to perform an area-wide testing and investigation program in the Acquisition Area,
    to evaluate the results of the program, and to develop a decommissioning and demolition program
    that would protect public health.
    -16-
    No. 2--08--0769
    Blickle first explained the nature and scope of the testing and investigation. CRA inspected
    and sampled both structures and soils in the Acquisition Area. With respect to structures, CRA
    inspected "600 plus" parcels in the Acquisition Area and looked for any "material[s] of concern that
    should be decommissioned prior to demolition." CRA inspected the structures for lead and asbestos
    and for "waste," subdivided by the United States Environmental Protection Agency (USEPA) into
    universal waste (fluorescent bulbs, batteries), household waste (cooking oils, cleaning agents,
    pesticides), and hazardous waste (determined by a specialized test). CRA found materials containing
    asbestos. CRA did not test for lead in applied paint on the structures but, rather, assumed that there
    was lead in all applied paint and planned to decommission the structures accordingly.
    Blickle testified that CRA's inspection for waste included testing areas of concern, like
    stained concrete. This sampling was guided by the Toxic Substances Control Act (
    15 U.S.C. §2601
    et seq. 2000)), which Blickle described as "the only procedure prescribed by the [USEPA] for
    sampling solid materials." CRA gathered 4,400 samples in all and sent them to an independent lab
    to be tested for the presence of hazardous waste according to the criteria of the Resource
    Conservation and Recovery Act of 1976 (RCRA) (
    42 U.S.C. §6901
     et seq. (2000)). Blickle testified
    that CRA found household and universal waste but no hazardous waste in the Acquisition Area.
    Blickle then explained CRA's methodology for soil sampling. CRA conducted two types of
    sampling: (1) sampling in areas of potential environmental concern (PECs); and (2) grid sampling.
    CRA identified PEC sites based on historical data showing the likely presence of contaminants in
    the soil. Grid sampling consisted of random testing within a grid of acre-sized lots imposed on a
    map of the Acquisition Area (with no overlap with PEC testing). Blickle testified that grid sampling
    was not required by the USEPA but that CRA did it as an extra precaution. Blickle testified that
    -17-
    No. 2--08--0769
    CRA took samples at approximately 170 PEC sites and approximately 200 grid sites. About 400
    discrete samples were taken in all.5 CRA took samples at depths recommended by a document
    entitled "Soil Screening Guidance: User's Guide," promulgated by the USEPA. CRA was not able
    to complete testing at 21 of the PEC sites because of "access issues." Blickle testified that he was
    confident that nothing was present at these 21 PEC sites that CRA had not already encountered
    elsewhere in the Acquisition Area. Blickle testified that CRA selected the chemicals for which to
    test a PEC sample based on the contaminants, e.g., petroleum, that the usage history of the site
    indicated would likely be present in the soil. Blickle testified that grid samples were tested for
    substances listed on the Priority Pollutant List established by the Federal Water Pollution Control
    Act, commonly referred to as the Clean Water Act (
    33 U.S.C. §1317
     (2000)).
    Blickle testified that the test results for each chemical were compared against the soil
    screening level for that chemical. Blickle used soil screening levels developed by Dr. Elizabeth
    Anderson of Exponent Corporation. Blickle testified that Dr. Anderson's screening levels are
    conservative and that an exceedance does not necessarily indicate that disturbance of the soil will
    be a risk to public health. Blickle testified that 99% of the PEC samples and 99% of the grid
    samples were below the screening levels. Blickle testified that the exceedances that were found
    would not preclude demolition, because CRA had measures to control emission of contaminants
    within levels acceptable for public safety.
    5
    There is some equivocation in the record between a "parcel" and a sampling "site" or
    "location." From what we gather, CRA took samples at 370 "locations" or "sites" within the 615
    legal parcels that comprise the Acquisition Area. A given parcel might contain more than one
    sampling site or location, and multiple samples might be taken at a given sampling site or location.
    -18-
    No. 2--08--0769
    Blickle then described CRA's planned decommissioning procedures. Blickle testified that
    CRA intends to remove all waste that can be "practically" taken from the structures. As for asbestos,
    Blickle noted that the handling and disposition of materials containing asbestos is controlled by the
    National Emissions Standards for Hazardous Air Pollutants (NESHAP) (
    40 C.F.R. §61
     et seq.
    (2008)), a series of federal regulations. Blickle explained that asbestos is of two types: "Regulated
    Asbestos Containing Material" (RACM) and non-RACM.                      The USEPA and the Illinois
    Environmental Protection Agency (IEPA) both must be notified of the presence of RACM in a
    structure designated for demolition. Prior to demolition, RACM must be entirely removed from the
    structure by a demolition contractor licensed in asbestos abatement. Non-RACM need not be
    removed prior to demolition. Blickle explained that, though such a measure is not required by law,
    CRA will dismantle rather than crush or implode structures containing non-RACM. As for lead,
    CRA will assume that all applied paint contains lead and will remove all flaked or flaking paint.
    Blickle next described the demolition controls that CRA developed to keep emissions of
    contaminants to safe levels during demolition. CRA will enclose the demolition area to exclude the
    public and will maintain a "buffer zone" between the demolition area and occupied properties. CRA
    will apply water to all structures to control release of dust and will use silk screens to filter the water
    running off the structures. Blickle characterized the wetting of structures as CRA's "primary" control
    on dust. CRA will also vacuum around the structures with a device designed to catch particles down
    to .3 microns in size. In addition, CRA will implement a "real time" air monitoring program in an
    effort to confine "visible dust" to the demolition area, per the dictates of the NESHAP. CRA will
    monitor airborne asbestos according to the standards of the Asbestos Hazard Emergency Response
    Act of 1986 (AHERA) (
    15 U.S.C. §2461
     et seq. (2000)) and lead levels according to the National
    -19-
    No. 2--08--0769
    Primary & Secondary Ambient Air Quality Standards (NAAQS) (
    40 C.F.R. §50.1
     et seq. (2008)).
    CRA derived from the AHERA and the NAAQS certain "action" and "trigger" levels for lead and
    asbestos. If an action level is exceeded, CRA will take corrective measures while continuing
    demolition. If a trigger is exceeded, CRA will cease demolition altogether until it achieves
    compliance with the emission standards. In addition to the foregoing, CRA will monitor the air for
    volatile organic compounds. Blickle admitted that CRA will not monitor for substances other than
    lead, asbestos, and volatile organic compounds. Blickle explained that demolition teams "never
    monitor for every constituent that's present, no matter what the site." The custom rather is to "select
    target compounds, indicator parameters to gauge your monitoring program."
    Blickle testified that CRA will further minimize soil disturbance by demolishing just to the
    "pad" or slab of a structure and by filling basements with concrete rather than digging out the walls.
    Blickle opined that CRA's demolition controls will insure that no "appreciable" deposition of
    chemicals will occur in residential areas inside or outside the demolition area. Blickle admitted that
    CRA made no quantitative estimate of "what would come off the site during demolition." CRA saw
    no need to make that calculation, because its controls "are protective of any type of generation of that
    material" and it did not believe "anything is going to come off" the site during demolition.
    Blickle acknowledged an October 31, 1997, letter from the IEPA to Nelson Steel & Wire,
    which had occupied in the Acquisition Area a parcel that is now the site of Pro Logis. The letter
    implies that at the site there had been some environmental issue for which remediation had been
    required. The letter refers to presently contaminated soil at the site but states that "no further
    remediation" is required at the site as long as certain terms are followed. The letter states in pertinent
    part:
    -20-
    No. 2--08--0769
    "PREVENTIVE, ENGINEERING, AND INSTITUTIONAL CONTROLS
    3.     Preventive:    a) A Site Health and Safety Plan for this remediation site is to be
    implemented in accordance with the Occupational Safety and Health
    Administration requirements to address possible worker exposure,
    should any further excavation and construction activities occure [sic]
    within the contaminated soil.
    b) The area of the northeastern retention basin, as identified on the
    Site Base Map, is prohibited from recreational use. Additionally, any
    future activity which would expose contaminated sediments within
    the northeastern retention basin will require implementation of an
    engineered barrier meeting the requirements of 35 Illinois
    Administrative Codes 742.1100 and 742.1105.
    Engineering: As delineated on the Site Base Map, a six (6) inch asphalt or
    equivalent material cap must remain in place over the contaminated
    soil. The cap must be properly maintained in the future as an
    engineered barrier to inhibit inhalation and ingestion of the
    contaminated media below the cap, as well as impede contaminant
    migration to groundwater.
    Institutional: Within the boundaries of the site, no person shall construct, install,
    maintain or utilize a water system or well other than the water supply
    and water services available from the nearest Public Water Supply.
    The provisions of this institutional control shall be applicable to all
    -21-

    water usage including, but not limited to, domestic, commercial and
    industrial uses and water for outdoor purposes."
    The letter also states that the conditions specified may be revised if "(a) Further investigation or
    remedial action has been conducted that documents the attainment of objectives appropriate for the
    new land use; and (b) A new letter is obtained and recorded in accordance with Title XVII of the
    [Illinois Environmental Protection Act] and regulations adopted thereunder." Blickle testified that
    the demolition of structures at the Pro Logis site will not disturb the cap that now sits over the
    contaminated soil at that site.
    Blickle testified that, in his professional opinion, CRA's decommissioning program and
    demolition controls will insure that the demolition of structures in the Acquisition Area is "clean"
    and not a threat to public health.
    Chicago's other witness was Dr. Elizabeth Anderson, a toxicologist at Exponent and an
    expert in assessing risks to public health from contaminants and pollutants. Dr. Anderson testified
    that a proper assessment of the risk posed by a proposed demolition has three steps: (1)
    characterizing the demolition site, which involves identifying chemicals of potential concern; (2)
    identifying potential receptors of emissions and pathways of exposure, such as inhalation and
    ingestion; and (3) determining the overall risk on the basis of the qualitative and quantitative data.
    The aim of the risk assessment approach is to insure that contaminants are not released in levels that
    can threaten public health.
    Dr. Anderson testified that, in her professional opinion, Blickle's plan for decommissioning
    the structures, controlling dust, and monitoring for lead and asbestos was suitably protective of
    public health. To evaluate the risk posed by soil disturbance, Dr. Anderson used a specialized risk
    -22-
    No. 2--08--0769
    assessment paradigm called the "screening level approach," which is approved by both the USEPA
    and the IEPA. Dr. Anderson explained that the aim of the screening level approach is to calculate
    the maximum soil concentration at which a substance, if released during a soil disturbance, will not
    endanger public health. Dr. Anderson drew her soil screening levels from the baseline values
    provided in the "Tiered Approach to Corrective Action Objectives" (TACO) (35 Ill. Adm. Code
    §742.100 et seq., adopted at 
    21 Ill. Reg. 7942
    , eff. July 1, 1997, as amended) promulgated by the
    IEPA.6 Dr. Anderson explained that TACO assumes that there has been both "a hazardous release"
    and "an enforcement action" and, accordingly, prescribes soil screening levels by which to plan
    appropriate corrective action. TACO may also be used "voluntarily," as she did here, where the issue
    is the risk involved in a prospective soil disturbance. Dr. Anderson testified that TACO soil
    screening levels are calculated differently for carcinogenic substances than for noncarcinogenic
    substances. Under TACO, exposure to carcinogenic substances must not cause greater than a 1 in
    1 million (1 x 10-6) chance of developing cancer over one's lifetime. Risk associated with
    noncarcinogenic substances, however, is measured not as a probability but as a hazard quotient, or
    "the ratio of the expected exposure to the regulatory limit." Under TACO, the hazard quotient for
    noncarcinogenic substances must not exceed one.
    Dr. Anderson testified that TACO considers the risk that demolition poses to both demolition
    workers and adjacent residents. TACO provides three tiers of screening values. Tier 1 provides
    6
    It became apparent in later testimony that Dr. Anderson provided screening levels for
    chemicals she considered relevant to the risk analysis and did so independently of Blickle's test
    results. Therefore, it was possible that Dr. Anderson calculated screening levels for chemicals that
    Blickle never detected.
    -23-
    No. 2--08--0769
    screening values for a certain baseline scenario, and Tiers 2 and 3 allow for modification of those
    values if the circumstances of a chemical release from soils differ materially from the Tier 1
    scenario. Dr. Anderson explained that Tier 1 presupposes a release of contaminants due to a "very
    gentle soil disturbance." Tier 1 also presupposes an exposure duration of 30 years for adjacent
    residents and 30 days for demolition workers. Dr. Anderson modified the Tier 1 scenario in several
    ways. First, she assumed, commensurate with the length of the planned demolition, that both
    residents and demolition workers in the Acquisition Area would be exposed to released chemicals
    for 260 days. Dr. Anderson testified that the baseline 30-year exposure for residents was not realistic
    in this case because contaminants were found at "very low levels" in the Acquisition Area and
    Blickle's demolition controls would forestall any "large depositions that would then cause long term
    risk."
    Second, Dr. Anderson assumed a greater soil disturbance than the baseline Tier 1 scenario
    and in fact employed a "Particulate Emission Factor" (PEF) 10 times more conservative than the Tier
    1 default factor.
    Third, as a precautionary measure, Dr. Anderson assumed that residents in the Acquisition
    Area would inhale released contaminants to the same degree as demolition workers. Dr. Anderson
    did not, however, assume any ingestion of contaminants by residents as she did for demolition
    workers, because ingestion by residents was unlikely given the degree of Blickle's controls.
    The fourth manner in which Dr. Anderson departed from Tier 1 was to use an additive risk
    analysis according to the guidelines of Tier 3. Dr. Anderson explained that an additive risk analysis
    considers the combined effect of exposure to multiple contaminants. Dr. Anderson emphasized that
    the additive risk analysis considers "contaminants detected--not suspected, not possibilities." Dr.
    -24-
    No. 2--08--0769
    Anderson also emphasized that the additive risk analysis considers separately the effects of
    noncarcinogenic and carcinogenic substances; TACO does not permit the combining of carcinogenic
    and noncarcinogenic effects into a single risk value. Finally, the additive risk analysis segregates
    effects to different parts of the body. Dr. Anderson testified that the screening levels resulting from
    her adjustments were more rigorous overall than even the conservative Tier 1 levels.
    Dr. Anderson then described Blickle's test results and his comparison of them to her
    screening levels.     Dr. Anderson noted that Blickle's test results showed "very, very low"
    concentrations of contaminants in the Acquisition Area. Blickle took these concentrations and did
    a "chemical by chemical" analysis, comparing each chemical to its screening level. Blickle found
    exceedances at 41 of the 370 locations he sampled. When Dr. Anderson did her own comparison
    using the additive risk model, she found exceedances at only 11 locations sampled. Dr. Anderson
    attributed this somewhat counterintuitive disparity to the specialized nature of additive risk analysis
    under TACO. For one, additive risk separates effects peculiar to discrete body parts; there is no
    "mixing of body parts." Furthermore, under TACO, "the cumulative risk of carcinogens [sic]
    contaminants attacking the same target must not exceed 1 x 10-4," not the standard benchmark of 1
    x 10-6.
    Dr. Anderson testified that, in an effort to be "more public health protective," Blickle
    designed his controls based on the 41 site-exceedances derived from his chemical-by-chemical
    analysis, not on the lower number of exceedances reached in Dr. Anderson's additive risk analysis.
    Dr. Anderson noted that, of the 41 exceedance sites, no soil disturbance causing a release would
    occur at 25 of the sites because either there are no structures at all on those sites or the soil that is
    contaminated is located below asphalt or concrete that will be undisturbed during demolition. Dr.
    -25-
    No. 2--08--0769
    Anderson testified that another 12 of the 41 locations showed exceedances only for arsenic and
    benzo(a)pyrene, and these were in concentrations at acceptable background levels that TACO sets
    for chemicals found "frequently in the environment." On yet another site, "the limits of detection
    were above the risk-base soil concentration levels," and Blickle "had very generally just included [it]
    as a positive sample even though it was never detected." Thus, there remained just three sampling
    locations with unmitigated exceedances.
    Asked if CRA had taken enough samples at each sampling location to be confident that it had
    measured the highest concentration of each contaminant found at the location, Dr. Anderson
    answered:
    "I suppose Mr. Blickle could have sampled every square inch. But that's not the point
    of a sampling program.
    The point of [a] sampling program is to capture the representative samples in a
    location."
    Dr. Anderson further defended CRA's sampling program:
    "If you're doing a focus sampling plan and you're trying to sample particularly the
    point where you think the concentration is going to be the highest and you don't really find
    anything that is of enormous concern--we did not find huge levels of contamination at this
    site--and then to proceed further to establish protective measures, I don't think you
    necessarily need to establish sampling plans that just continue to sample and to sample and
    to sample, when at this site, as I said ***, we really don't find that many enormous concerns.
    We found very, very, few samples that exceeded the screening levels."
    -26-
    No. 2--08--0769
    Dr. Anderson testified that CRA did not intend to remove the protective barrier in place at
    the Nelson Wire/Pro Logis site, but, if there were a soil disturbance, "it would need to be addressed
    with the [IEPA]."
    Dr. Anderson testified that, in her professional opinion, the demolition planned by CRA will
    not threaten public health because CRA's plan for decommissioning the Acquisition Area is
    comprehensive and sound, the soil in the Acquisition Area has low concentrations of contaminants,
    and the demolition controls designed by CRA will adequately control emission of contaminants from
    the structures and soils.
    Plaintiffs' first witness was Stanley Popelar, a geologist and expert in site assessment
    employed by Environ. Popelar's testimony was focused primarily on CRA's soil sampling program,
    which he found inadequate. Popelar emphasized first that soil samples were taken at a relatively
    small number of legal parcels in the Acquisition Area. Popelar noted that CRA took samples at only
    147 of the 615 parcels in the Acquisition Area. Moreover, CRA identified 61 PEC parcels but took
    samples at only 37.7
    Popelar criticized CRA's general sampling methodology. Popelar testified that CRA's PEC
    sampling concentrated almost exclusively on commercial and industrial properties even though
    residential properties regularly contain such contaminants as lead from paint, pesticides, chemicals
    7
    Again, the testimony at the hearing draws a distinction between a parcel and a sampling
    location. As seen from Blickle's testimony, CRA often identified more than one sampling location
    within a given parcel and often took more than one discrete sample within a sampling location. Still,
    it is difficult to reconcile Blickle's testimony that only 24 PEC sampling sites remained to be tested
    with Popelar's testimony that 37 legal parcels remained for PEC testing.
    -27-
    No. 2--08--0769
    for treating lumber, heating oil residue, and household wastes. Popelar asserted that this deficiency
    in the PEC sampling was not remedied by the grid sampling, which also did not cover all residential
    properties in the Acquisition Area.
    Popelar also criticized CRA's methodology with respect to the sites it did sample. Popelar
    noted that, once CRA found a sample in a given location that tested positive for a contaminant, CRA
    did not "step out" from the point of the sample, i.e., take further samples to determine the total
    quantity of that contaminant at the sampling location. Popelar testified that, without knowing the
    total quantity of a contaminant in an area, one cannot know what quantity of that contaminant will
    be released during a soil disturbance, and, without knowing emission levels, one cannot design
    appropriate emission controls. Popelar also opined that CRA did not bore deeply enough when
    taking samples. Additionally, in the residential properties that were grid-sampled, CRA "typically
    put the soil borings out in the middle of the yard in areas [where CRA was] least likely to find
    contamination, not near the structures, not near [the] sources of residential contaminants."
    Popelar maintained that, though underground septic and heating oil tanks are common in
    residential properties in the Acquisition Area, CRA did not search for such tanks in many of the
    residential areas. Popelar identified specifically a residential area north of Irving Park Road in
    Bensenville that CRA had not surveyed for septic or heating oil tanks.
    Popelar concluded that CRA's sampling was "not area-wide" or "comprehensive" and that
    CRA failed to "identify the maximum concentrations present and/or the quantities they might be
    dealing with." Popelar admitted that Environ did not take its own samples from the Acquisition
    Area. Robert Adams, also employed by Environ, testified that he has experience in developing and
    evaluating decommissioning and demolition plans. Adams testified that the basic shortcoming in
    -28-
    No. 2--08--0769
    CRA's demolition controls is that they are based on incomplete data. Adams observed that a large
    number of residential properties have not been sampled by CRA.           Even with respect to the
    properties it has sampled, CRA has "done no assessment or review to determine what kinds of
    emissions will be coming off the site during the demolition process." Because "you need to know
    what is going to come off of the site [during demolition] to determine what the necessary controls
    are," CRA has no basis for claiming that its controls will limit emissions within levels consistent
    with public health.
    Adams also questioned aspects of CRA's air monitoring program. Adams asserted that
    CRA's monitoring system was not sufficiently comprehensive because asbestos, lead, and volatile
    compounds are not reliable proxies for other contaminants, contrary to CRA's position. Adams also
    claimed that CRA's lead monitoring instruments are not sensitive enough to detect emissions at
    CRA's proposed action and trigger levels.
    Adams admitted that he has not taken samples from, or otherwise investigated or examined,
    the Acquisition Area. He also admitted that he himself has made no estimate of the emission levels
    for any contaminant that could be released during demolition.
    Dr. Frank Jones, a toxicologist at Environ and an expert in risk assessment, testified to the
    multiple points on which he disagreed with Dr. Anderson's screening level approach. First, Dr. Jones
    disagreed with Dr. Anderson's rejection of ingestion as a possible pathway of exposure for residents
    inside or outside the Acquisition Area. Second, Dr. Jones challenged Dr. Anderson's PEF. Dr. Jones
    stated that TACO's baseline PEF is the "Cowherd factor," which assumes "just bare exposed soil
    with wind blowing across the soil." Dr. Jones noted that Dr. Anderson, to account for the greater
    soil agitation caused by demolition, simply multiplied the Cowherd factor by 10. Dr. Jones opined
    -29-
    No. 2--08--0769
    that, though TACO mandates multiplying the baseline factor by 10, there is no scientific basis for
    choosing 10 as the multiplier. Dr. Jones dismissed TACO's enhanced PEF as "simplistic" and noted
    that the USEPA has developed more sophisticated emissions factors.
    Third, Dr. Jones asserted that Dr. Anderson was mistaken in substituting an exposure
    duration of 260 days for the 30-year default duration in TACO Tier 1. Dr. Jones explained that the
    default standard assumes that contaminants will travel from a demolition area into adjoining
    residential areas and, once deposited, will cause continual exposure until dissipated or transported
    elsewhere. Dr. Anderson made the substitution because she believed there would be no deposition
    of material that could have long-term ill effects. Dr. Jones criticized this belief as unfounded
    because CRA had not measured the quantity of each contaminant in the soil and therefore had an
    incomplete picture of emission levels or deposition amounts. Dr. Jones cited a body of literature
    finding that, even with "dust suppression" controls in place, demolition of structures causes
    "significant levels of deposition of dust" outside the demolition area. Dr. Jones concluded that Dr.
    Anderson had no cause for departing from the default exposure duration in TACO Tier 1. Dr. Jones
    admitted, however, that the prevailing winds in the vicinity of the Acquisition Area blow from the
    southwest. Thus, the Acquisition Area, situated between O'Hare to the northeast and the remaining
    sections of Bensenville to the west and southwest, is mostly downwind from the other areas of
    Bensenville.
    Dr. Jones testified that, though he disagreed with Dr. Anderson's screening levels, he did not
    calculate his own screening levels but used Dr. Anderson's to perform an additive risk analysis that
    considers the combined effect of multiple agents. Dr. Jones employed the additive risk approach of
    a USEPA document entitled "Risk Assessment Guidance for Superfund, Volume I, Human Health
    -30-
    No. 2--08--0769
    Evaluation Manual" (RAGS). The method of the RAGS involves dividing "your acceptable risk
    level by the number of potential chemicals that your--that you may have present at the site." Dr.
    Jones stressed that he considered the additive effects of carcinogens separately from the additive
    effects of noncarcinogens; he agreed that the RAGS does not allow one "to take the noncancer risk
    and add it to the cancer risk to determine the total risk." Dr. Jones testified that he calculated the
    respective additive risks for carcinogens and noncarcinogens by first adding together all screening
    levels Dr. Anderson provided, which yielded a total screening level. He then divided this figure, in
    the case of noncarcinogens, by 120 (the total number of chemicals for which Dr. Anderson provided
    screening levels), and, in the case of carcinogens, by 50 (the total number of carcinogenic chemicals
    for which Dr. Anderson provided screening levels). The higher divisor for noncarcinogens was
    necessary because "all chemicals have a noncarcinogenic effect, whether they are a carcinogen or
    a noncarcinogen." Dr. Jones acknowledged that he divided the total screening value not "by the
    chemicals actually detected" but by "the total number of chemicals for which [Dr. Anderson]
    provided a screening level."8 He noted that, "even if it was nondetected, [a] chemical might still
    have been of concern." He explained in the following colloquy:
    "Q. You used *** the substances that were listed in Dr. Anderson's table [of
    screening values] did you not?
    A. That is correct.
    Q. And you mentioned that some of the chemicals she had listed came back as
    nondetect; isn't that right?
    8
    It is implied here that Dr. Anderson created her list of screening values independently of
    what Blickle detected in the Acquisition Area.
    -31-
    No. 2--08--0769
    A. That is what I've been told this morning.
    Q. Okay. And one of the problems with nondetect is that the sensitivity level of the
    chemistry may be above the level of health concern; isn't that right?
    A. That is--in the field of risk assessment, if you have a detection limit that is higher
    than your health-based concern, you would assume that the chemical might still be there at
    half the detection level.
    Q. Because the limits of the chemical lab may be, you have the chemical there and
    a health risk, but the laboratory isn't able to analyze it; is that correct?
    A. Exactly."
    Dr. Jones claimed that TACO dictates the same divisors as the RAGS for an additive risk analysis.
    Dr. Jones testified that, under the additive risk analysis of the RAGS, he found exceedances
    at 52 of CRA's sampling locations, compared to Blickle's 41 exceedances. If he had used the
    unmodified TACO Tier 1 values (a risk limit of 1 x 10-6, exposure through both ingestion and
    inhalation, and an exposure duration of 30 years), he would have found exceedances at "most" of
    CRA's sampling locations. Dr. Jones noted that, under TACO, if an additive risk analysis yields
    screening values more rigorous than the Tier 1 values, "the number[s] would default back to the Tier
    1 number[s]." Dr. Jones considered this proviso in TACO "policy-based" not "health-based." If not
    for it, an additive risk analysis using the strict Tier 1 values would yield exceedances at every
    sampling location in the Acquisition Area. Dr. Jones admitted that he was "supposed to calculate
    additive risk by target organ" but did not do so.
    Dr. Jones testified that there were "too many gaps" in CRA's data for Chicago to conclude
    that the demolition would not endanger public health. Particularly, CRA failed to calculate the total
    -32-
    No. 2--08--0769
    quantities of contaminants found at each sampling location. Without this knowledge, CRA could
    not develop appropriate demolition controls because, "if you don't know what's there, you can't
    control for it." Dr. Jones acknowledged that it is acceptable to obtain the average concentration of
    a contaminant at a sampling location as long as the range of sampling is broad enough. CRA,
    however, did not attempt to find the average concentration at any sampling location.
    Michael Paige, a Bensenville official responsible for insuring compliance with the village's
    codes, testified that he met with Chicago officials to discuss the proposed demolition. During these
    meetings, he informed Chicago officials about the likelihood of underground storage tanks and septic
    fields in the residential areas north of Irving Park Road. Paige also testified that, as of the hearing,
    13 residential parcels in the Acquisition Area were still occupied.
    Kenneth Mundt, who had submitted a sworn declaration in support of plaintiffs' original
    motion for injunctive relief, testified that he was the leader of the team of Environ employees who
    evaluated CRA's proposed decommissioning and demolition procedures. Mundt and his team tested
    CRA's work against the risk assessment framework Mundt had laid out in his sworn declaration.
    This three-stage method consists of: (1) conducting a "comprehensive area-wide sampling plan,"
    which involves measuring the "concentration, quantity[,] and type of contaminants" in the area
    designated for demolition and calculating the extent to which the demolition will expose demolition
    workers, and residents in the vicinity, to contaminants; (2) determining whether the likely exposure,
    if any, is consistent with acceptable levels of public health protection; and (3) developing measures
    to limit exposure to within acceptable levels. Mundt testified that step one is "critical" for the others
    because if "good scientific data" is lacking, "whatever controls are based on [the] improper risk
    assessment might not be adequately protective."
    -33-
    No. 2--08--0769
    Mundt opined that CRA did not conduct step one properly. Mundt asserted that CRA's
    survey of the demolition site was deficient because CRA did not take PEC samples at all residential
    properties, where the soils likely contained pesticides and lead from exterior paint. Mundt also noted
    that CRA did not test for pesticides in any grid or PEC sample even though they were likely present
    in the Acquisition Area. Mundt considered these gaps in data "irresponsible." Also, Mundt
    considered grid sampling intrinsically flawed as a sampling methodology because it is not directed
    by historical property use. Mundt testified that he did not consider grid sampling appropriate "for
    any purpose" and did not believe that the USEPA approves grid sampling.
    Mundt criticized CRA's sampling program for the additional reason that it did not utilize
    "stepping out" sampling. Mundt noted that "stepping out" sampling is important because, "[i]f levels
    of contaminants exceed certain thresholds, we would then want to know whether we were at the very
    edge of the contaminated area, [or] at the center of it." "Stepping out" sampling "confirm[s] what
    the highest concentrations are of a particular contaminant of concern as well as the quantity of the
    particular contaminant of concern." Mundt admitted that he is not trained in soil sampling and has
    never taken soil samples himself. Mundt also admitted that Environ did no soil sampling of its own
    but simply critiqued CRA's methods.         Mundt concluded that, because CRA's sampling was
    inadequate, there was insufficient data "to make a scientifically or technically supportable judgment
    that going forward with the demolition at this time would not pose a significant health risk" to
    residential areas in or near the Acquisition Area.
    In rebuttal, Chicago called Dr. Anderson, who addressed Dr. Jones' criticisms of her risk
    assessment methods and also critiqued his proposed methods. Dr. Anderson testified that a proper
    risk assessment of the planned demolition in the Acquisition Area did not require her to measure the
    -34-
    No. 2--08--0769
    total quantity of each contaminant in a sampling location because she used a soil disturbance model
    that assumed "limitless amounts of contaminant in the soil." Referencing Dr. Jones' additive risk
    method, Dr. Anderson asserted that she knows of no government agency that prescribes including
    "suspected" or "non-detected" chemicals in the divisor for additive risk analysis. Dr. Anderson
    suggested that such a method is "arbitrary" and "make[s] no sense." Dr. Anderson followed instead
    TACO's additive risk method, which provides that the divisor need include only chemicals "actually
    detected at the site." Dr. Anderson noted that Dr. Jones, by his own admission, did not "develop his
    screening levels based on target organs." Dr. Anderson suggested that Dr. Jones' analysis was further
    flawed because "he combined the cancer risk and the non-cancer risk to the same chemical to come
    up with his screening level."
    Dr. Anderson testified that, since her testimony in Chicago's case-in-chief, she recalculated
    her screening levels using straightforward Tier 1 factors and found exceedances at 37 sampling
    locations. Dr. Anderson testified that this was the same number of exceedances Popelar found when
    he applied Dr. Jones' screening levels.
    In surrebuttal, Dr. Jones testified that, since his testimony in plaintiffs' case-in-chief, he redid
    his additive risk model using the number of chemicals detected, not merely suspected. The result
    was still a set of screening levels that fell below TACO Tier 1 baseline norms (but that defaulted to
    the Tier 1 standards due to TACO's reversionary clause). Dr. Jones admitted that he combined the
    carcinogenic risk with the noncarcinogenic risk for at least three chemicals for which he provided
    screening levels. Dr. Jones claimed that this was an "inadvertent" error and that he was "a little
    sloppy" in calculating his screening levels. Dr. Jones noted that, for the three examples he identified,
    the noncarcinogenic risk had such a low value that it added virtually nothing to the carcinogenic risk.
    -35-
    No. 2--08--0769
    On August 7, 2008, in a lengthy written opinion, the trial court dissolved the preliminary
    injunction against Chicago's demolition of structures in the Acquisition Area. The trial court began
    with a general overview of the evidence:
    "The Defendant, City of Chicago, presented two expert witnesses, Mr. Fred Blickle
    of Conestoga-Rovers and Associates ('CRA') and Dr. Elizabeth Anderson of Exponent, Inc.
    ('Exponent'), in support of its position: (i) that proper precautionary measures will be taken
    during demolition to prevent unsafe exposure to any potentially harmful materials in the
    Acquisition Area; (ii) that Plaintiffs' contention that the Acquisition Area presents significant
    uncontrollable risks to public health is without foundation; and (iii) that Plaintiffs' claims of
    endangerment were not only inaccurate and speculative at the time they were made
    (particularly since they were not based on any investigation, sampling, testing, or modeling
    of the Acquisition Area by the Plaintiffs), but[,] moreover[,] have no legitimate evidentiary
    basis, now that there has been extensive area-wide investigation and sampling of the
    Acquisition Area.
    The Plaintiff[s], Village of Bensenville et al., countered with their position as
    presented by their four expert witnesses, Mr. Stanley Popelar, Dr. Frank Jones, Mr. Robert
    Adams, and Dr. Kenneth Mundt, all of ENVIRON International Corporation ('ENVIRON'),
    that it is premature to determine whether there will be endangerment to the public health,
    because more investigation and sampling must first be done in the Acquisition Area.
    Although Plaintiffs' experts acknowledged that they have not investigated, sampled[,] or
    tested the Acquisition Area at any time and consequently have no data of their own on which
    -36-
    No. 2--08--0769
    to base their contentions ***, Plaintiffs nonetheless contend that no demolition activities can
    now proceed."
    To illustrate what it considered the pith of the controversy between the parties, the trial court
    collected the following subject headings from plaintiffs' proposed order and findings of fact:
    "A. Chicago-CRA sampling was incomplete and inadequate
    B. There was no proper risk assessment of the health risks to Bensenville residents and their
    families
    a. The Level of Public Health Protection for Residents of Bensenville and
    their Families: 1 x 10-6 Cancer Risk and A Hazard Index of 1
    b. The Translation of the Health Based Objectives of 1 x 10-6 and a Hazard
    Index of 1 into health based concentrations and quantities of toxic chemicals
    i. The Foundation Assumptions To Determine Residential Health
    Protection--30 years vs. 260 days
    ii. Multiple Toxic Chemical v. Single Chemical Exposure
    iii. Chicago and Dr. Anderson's Approach--Ignore Ingestion and the
    30-year Exposure Ingestion Pathway
    iv. Chicago and Dr. Anderson did not report individual chemical
    concentrations for a health level of protection of 1 x 10-6 and a Hazard
    Index of 1--using both the traditional residential assumptions of 30 yr.
    ingestion as well as multiple chemical exposure
    c. Chicago conducted no transport dispersion or deposition analysis to
    determine what concentration and amounts of toxic contaminants from the
    -37-
    No. 2--08--0769
    demolition activity would be deposited into the homes, day care centers,
    retirement homes and schools of Bensenville residents or their families
    d. Dr. Anderson's rationale as to why there was no need to do a residential
    exposure analysis at the residential receptors (i.e., the homes and schools).
    e. The dispute between Dr. Anderson and Dr. Jones Relating to Multiple
    Chemical Exposure
    C. There is No Evidence that the Demolition Controls and Monitoring Proposed by Chicago
    are Adequate to Protect Public Health.
    (1) Lead controls inadequate
    (2) Controls and Monitoring for toxic contaminants in dust inadequate to protect
    public health."
    After reviewing the standards for granting injunctive relief, the trial court made the following
    general findings:
    "A year has passed since this Court's original injunctive ruling. The area-wide field
    investigation and sampling program that I ordered Chicago to complete was in fact
    completed.
    I was privileged to hear the expert testimony of both Plaintiff's [sic] and Defendant's
    [sic] over the course of the four day hearing. Through that testimony, I 'became educated'
    in regard to the standards of the United States Environmental Protection Agency; the Illinois
    EPA; the National Emissions Standard for Hazardous Air Pollutants, the Asbestos
    'NESHAP'; regulated ACM and non RACM; the Asbestos Hazardous Emergency Response
    Act ('AHERA'); the National Ambient Air Quality Standards for Lead ('NAAQS'); risk
    -38-
    No. 2--08--0769
    assessment procedures promulgated by the IEPA in its regulatory program called 'Tiered
    Approach to Corrective Action Objectives,' Tier 1 and Tier 3 ('TACO'); as well as the Illinois
    EPA's previously issued No Further Remediation Letter ('NFR') on October 31, 1997,
    pertaining to the ProLogis site contained within the demolition area.
    I now see that there are sufficient governmental agencies and regulations that can
    oversee this demolition project. In my opinion any further oversight by the Court would be
    done without proper authority.
    By this Court attempting to exceed it's [sic] authority and to go in and oversee the
    entire environmental activities for the proposed demolitions would make this Court a
    revolving door for the parties to constantly come in requesting the Court to evaluate and
    review the various continuing steps and missteps which might occur in the demolition
    process. This Court would be called upon to be a self-imposed 'environmental protection
    agency' and/or risk assessment manager that would be constantly micromanaging the
    demolition process and having numerous hearings with differing experts [sic] opinions on
    what should and shouldn't be done at each step of the process.
    That would leave the Court to impose its own judgment pertaining to environmental
    issues where agencies and regulations already exist as an oversight.
    As noted herein[,] there are guidelines as to what is appropriate and there are agencies
    that can oversee same with their enforcement divisions as that of the EPA's.
    In my opinion[,] I don't have a basis to impose any further guidelines. This Court
    asked for a certain investigation to be done and in my opinion that investigation has been
    successfully done. That investigation satisfied the basics of what this Court wanted to see
    -39-
    No. 2--08--0769
    from the Defendant before they [sic] started the process of demolition. I am now satisfied
    by the fact that the environment protection and other agencies can continue to oversee this
    project should there be violations of regulations, codes[,] or the like.
    This Court has accomplished what it wanted to do when it issued the TRO and
    Preliminary Injunction on a previous occasion and ordered the Defendant to do certain work
    to ensure that the residents were protected from many concerns that might have existed
    because of unregulated or uncontrolled activity by the City of Chicago in regards to
    demolition.
    It is appropriate for demolition to commence now under the standards laid out by the
    expert testimony of the City of Chicago. Further delay creates inordinate safety issues
    pertaining to the existence of vacant unoccupied structures as well as the resultant safety
    issues within the approximate three hundred acres known as the Acquisition Area. That area
    with all structures properly and safely removed eliminates the current eye sore condition and
    eliminates the numerous concerns of fire, vandalism, and individual injuries to the public.
    Based on the foregoing[,] there is a separate remedy with the enforcement divisions
    of the various environmental protection agencies that would not require judicial
    intervention." (Emphases in original and added.)
    The trial court then made specific factual findings as to each of the prerequisites for a
    preliminary injunction. See Grandberg v. Didrickson, 
    279 Ill. App. 3d 886
    , 888-90 (1996) (stating
    prerequisites for a preliminary injunction). The court said:
    "1. Ascertainable Claim for Relief
    -40-
    No. 2--08--0769
    Here, Plaintiffs claimed in their pleadings, in pertinent part, that they were entitled
    to continuing injunctive relief because the City's planned demolition in the Acquisition Area
    will endanger residents in Bensenville.
    However, by the time of the July 7-10 hearing, the status quo as to residential
    occupancy in the Acquisition Area had materially changed. *** [A]s the testimony
    established, the number of residential occupied parcels has been reduced to only thirteen.
    Moreover, as the evidence established, the planned demolition will be protective of all
    remaining residents and Bensenville residents adjacent to the Acquisition Area.
    Accordingly, the strength of Plaintiffs' ascertainable claims has been materially
    diminished, a factor which the Court may take into account in deciding whether Plaintiffs are
    entitled to continuing equitable relief.
    2.Likelihood of Success on the Merits
    ***.
    A court may enjoin an anticipated nuisance only where it clearly appears that a
    nuisance will necessarily result. [Citation.] ***
    In this case, the Plaintiffs have not established that the City's planned demolition,
    with the testing and controls to be put into place, constitutes a current, existing public
    nuisance or that the public health will be endangered from demolition. Consequently,
    Plaintiffs were required, but failed, to establish that there is a fair question that they have a
    likelihood of success on the merits. I note this especially in light of the fact that the Plaintiffs
    have not performed any independent testing or evaluative field studies of their own! They
    -41-
    No. 2--08--0769
    have only taken issue with that performed by the Defendant. As such[,] the Plaintiff[s]
    [have] not met their burden of proof for continuing injunctive relief.
    3. Irreparable Harm
    Plaintiffs have not established that they will be subject to irreparable harm as a result
    of the demolition for much of the same reason that they have not established a fair question
    of likelihood of success on the merits of their nuisance claim.
    Plaintiffs have not established that they will be endangered by the City's planned
    demolition. As discussed above, Plaintiffs' experts at most testified that there may be an
    issue of concern or that they were uncertain or needed further data. However, these tentative
    questions and concerns do not constitute actual harm. Moreover, as the evidence at the
    hearing further established, not only will proper precautionary measures be taken during
    demolition through the application of CRA's decommissioning and demolition controls ***
    and air monitoring program *** to prevent any unsafe exposure to any potentially harmful
    materials in the Acquisition Area, but Plaintiffs' claims that the Acquisition Area presents
    significant uncontrollable risks to public health are simply without foundation.
    4. No Adequate Remedy at Law
    An additional element to be considered with regard to a decision as to whether
    continuing injunctive relief should issue is whether Plaintiffs have an adequate remedy at
    law.
    If Plaintiffs had established their allegations that the City's demolition will endanger
    public health, the Plaintiffs would likely have no adequate remedy at law. But, as indicated
    -42-
    No. 2--08--0769
    above, Plaintiffs have failed to do so, and consequently, the Court cannot grant the
    continuing preliminary injunctive relief which Plaintiffs seek.
    A separate remedy does exist with the enforcement divisions of various federal and
    state environmental protection agencies as created by the legislative bodies. There is no
    further authority or basis for judicial intervention by this court.
    5. Balancing the Hardships
    The Court must also balance the hardships and the public interest in making its
    determination regarding whether equitable injunctive relief should issue. *** Balancing the
    hardships and the public interest clearly weigh in favor of terminating the preliminary
    injunction. This determination is not made with an evaluation of necessity, which this Court
    excluded from this hearing as that issue is currently pending in an eminent domain action
    before Judge Culliton of the 18th Judicial Circuit. But the legislative history is relevant to
    this determination.
    The Illinois legislature has determined that the OMP is a project vital to the public
    interest. ***
    The evidence demonstrates that the demolition will occur in a manner protective of
    public health. As previously referenced in this opinion, the prompt demolition of City-
    owned buildings clearly outweighs Plaintiffs' unsubstantiated and admittedly uncertain
    claims of harm concerning the planned demolition.
    For all of these reasons, the balance of hardships weighs in favor of demolition in the
    Acquisition Area, and the public interest amply supports proceeding with demolition as
    planned by CRA on behalf of the City of Chicago." (Emphases in original and added.)
    -43-
    No. 2--08--0769
    The court ordered that the demolition:
    "comply with all applicable state and federal environmental laws with respect to
    decommissioning and demolition of the Acquisition Area buildings, and associated building
    materials, equipment and contents, including but not limited to applicable provisions of the
    Toxic Substances Control Act, and regulations thereunder, including 40 C.F.R. Part 761; the
    Resource Conservation and Recovery Act, and regulations thereunder, including 40 C.F.R.
    Part 273; the Clean Air Act NESHAP for asbestos, 40 C.F.R. Part 61, and other federal and
    state regulations pertaining to asbestos in the demolition context; federal and state law
    pertaining to removal of underground storage tanks; and the Occupational Safety and Health
    Act and regulations issued thereunder, including 29 C.F.R. 1926, Subpart T."
    The court further directed Chicago to complete any further testing of structures or soils that it
    "determines is necessary" before beginning demolition in those areas.
    On August 8, 2008, plaintiffs moved for a stay of the order lifting the injunction, pending
    appeal. The court refused to grant "an indefinite stay" but entered a stay until September 10. On
    August 14, plaintiffs appealed, under Supreme Court Rule 307(a)(1) (188 Ill. 2d R. 307(a)(1)), the
    order lifting the injunction. Plaintiffs also appealed under Supreme Court Rule 304(a) (210 Ill. 2d
    R. 304(a)) the order dismissing counts I through IV of plaintiffs' complaint.
    On August 18, plaintiffs moved this court for a stay of the August 7 order lifting the
    injunction. We granted the motion and stayed the order pending further order of this court.
    DISCUSSION
    I. Dismissal of Counts I through IV
    -44-
    No. 2--08--0769
    We address first plaintiffs' challenge to the dismissal of counts I through IV of their second
    amended complaint. Counts I and IV were dismissed under section 2--619 of the Code and counts
    II and III under section 2--615 of the Code.
    A. Counts I and IV
    "A motion to dismiss under section 2--619(a)(9) admits the legal sufficiency of the complaint
    and raises defects, defenses, or other affirmative matters that appear on the face of the complaint or
    are established by external submissions and that act to defeat the plaintiff's claim." Board of
    Trustees of Community College District No. 502 v. Department of Professional Regulation, 
    363 Ill. App. 3d 190
    , 196 (2006). A dismissal under section 2--619 is generally reviewed de novo. Board
    of Trustees, 363 Ill. App. 3d at 196.
    Count I seeks a declaration that: (1) the Act does not override the requirement of the Illinois
    Constitution "that the courts *** decide after an evidentiary hearing whether any particular parcel
    is necessary" for a public purpose; and (2) Chicago did not provide the requisite justification for
    "taking" properties in the Acquisition Area. Count I also asks that Chicago be ordered to restore "to
    their prior state and condition" the properties it "acquired" from the Acquisition Area and that
    Chicago be enjoined from "further acquisitions"of property in Bensenville "under any claim that the
    properties are necessary" for the OMP until Chicago proves its compliance with constitutional
    requirements.
    Before reviewing the trial court's grounds for dismissing count I under section 2--619, we
    touch briefly on that part of count I in which plaintiffs seek a declaration that the Act does not trump
    the constitutional restrictions on the taking of property. The trial court did not expressly rule on this
    request, but its remarks evince agreement with plaintiffs on the Act's relationship to the Illinois
    -45-
    No. 2--08--0769
    Constitution. In its recitation of the applicable law, the trial court stated: "If property is not
    necessary for the public project, there is no constitutional authority to take the property--despite what
    the Legislature has asserted in the authorizing statute." (Emphasis added.) This is a correct
    statement of the law. Article I, section 15, of the Illinois Constitution, the takings clause, provides:
    "Private property shall not be taken *** for public use without just compensation as provided by
    law." Ill. Const. 1970, art. I, §15. The takings clause " 'is a restraint and limitation placed upon the
    exercise of [the condemnation power] as against the right of the private citizen except in those cases
    where public necessity requires the taking of private property for public use,' " and "[t]he legislature
    *** cannot, by delegating the power of eminent domain, dispense with constitutional requirements
    restricting its use, including the requirement of 'necessity.' " YWCA, 
    86 Ill. 2d at 232-33
    , quoting
    Ryan, 
    357 Ill. at 154
    ; see also Davis v. Brown, 
    357 Ill. App. 3d 176
    , 183 (2005) ("the legislature
    cannot enact a statute that overrides or circumvents the constitution").
    Despite agreeing with plaintiffs that the Act is subservient to the Illinois Constitution, the
    trial court dismissed the whole of count I. Presumably, the trial court considered the plea for a
    declaration moot upon finding other affirmative matter under section 2--619 that barred plaintiffs'
    claim that Chicago did not meet the constitutional requirements for acquiring the properties in
    Bensenville. See Sadler v. Creekmur, 
    354 Ill. App. 3d 1029
    , 1039-40 (2004) (mootness is a ground
    for dismissal under section 2--619). In any event, plaintiffs complain of no error in the trial court's
    disposition of their request for a declaration that the Act does not override constitutional
    requirements. Rather, it seems their goal in pressing for that declaration was to clarify that, as they
    claim in their brief, the Act does not prohibit them from "proceed[ing] with adjudication of their
    allegations that Chicago's claims of constitutional necessity for hundreds of properties in Bensenville
    -46-
    No. 2--08--0769
    are false and inaccurate." The trial court agreed, as do we, that the Act presents no such bar.
    Whether an obstacle in section 2--619 exists elsewhere is another matter.
    In presenting its reasons for dismissing count I under section 2--619, the trial court
    distinguished two groups of properties: (1) plaintiffs' own properties in the Acquisition Area,
    currently the subject of the eminent domain action before Judge Culliton; and (2) all other properties
    in the Acquisition Area. (The trial court assumed that all but plaintiffs' properties have been
    acquired by Chicago.) The trial court found these component claims barred by different affirmative
    matter.
    First, with respect to plaintiffs' own properties, the trial court determined that plaintiffs had
    "an identical cause of action" before Judge Culliton and could "obtain complete relief" in that
    proceeding. The court held, therefore, that this component of count I was barred under section
    2--619(a)(3) of the Code, which provides for dismissal where "there is another action pending
    between the same parties for the same cause" (735 ILCS 5/2--619(a)(3) (West 2006)).
    "Section 2--619(a)(3) furthers judicial economy by avoiding duplicative litigation."
    Combined Insurance Co. of America v. Certain Underwriters at Lloyd's, London, 
    356 Ill. App. 3d 749
    , 753 (2005). "With respect to whether the actions are for the same cause, the crucial inquiry is
    whether both arise out of the same transaction or occurrence, not whether the legal theory, issues,
    burden of proof, or relief sought materially differs between the two actions." Jackson v. Callan
    Publishing, Inc., 
    356 Ill. App. 3d 326
    , 337 (2005). The "same parties" requirement of section
    2--619(a)(3) is satisfied " 'where the litigants' interests are sufficiently similar, even though the
    litigants differ in name or number.' " Combined Insurance Co., 356 Ill. App. 3d at 754, quoting
    Doutt v. Ford Motor Co., 
    276 Ill. App. 3d 785
    , 788 (1995). Even when the "same cause" and "same
    -47-
    No. 2--08--0769
    parties" requirements are met, section 2--619(a)(3) does not mandate automatic dismissal.
    Combined Insurance Co., 356 Ill. App. 3d at 754. Rather, the decision to grant or deny a section
    2--619(a)(3) motion is discretionary with the trial court, unlike motions under other subsections of
    section 2--619 or under section 2--615. Combined Insurance Co., 356 Ill. App. 3d at 754. The
    reason is that "a section 2--619(a)(3) motion *** is inherently procedural and urges the trial court
    to weigh several factors to determine whether it is appropriate for the action to proceed." Combined
    Insurance Co., 356 Ill. App. 3d at 753. The following factors are relevant: (1) comity; (2) the
    prevention of multiplicity, vexation, and harassment; (3) the likelihood of obtaining relief in the
    foreign jurisdiction; and (4) the res judicata effect of a foreign judgment in a local forum. In re
    Estate of Hoch, 
    382 Ill. App. 3d 866
    , 869 (2008). "An abuse of discretion occurs when the ruling
    is arbitrary, fanciful, or unreasonable, or when no reasonable person would take the same view."
    Favia v. Ford Motor Co., 
    381 Ill. App. 3d 809
    , 815 (2008).
    We find no abuse of discretion in the trial court's application of section 2--619(a)(3) to
    plaintiffs' claim that Chicago has not fulfilled its constitutional burden of proving that their
    properties are necessary for the OMP. First, the present proceeding and the proceeding before Judge
    Culliton are for the "same cause." The matter before Judge Culliton is an eminent domain
    proceeding by which Chicago seeks to acquire plaintiffs' properties for the OMP. In that proceeding,
    plaintiffs contend that their properties are not necessary for either Phase 1 or Phase 2 of the OMP.
    Plaintiffs present the identical challenge here. The actions also involve the same parties. Plaintiffs
    are all parties to the suit before Judge Culliton and so their interests naturally are well represented
    there.
    -48-
    No. 2--08--0769
    Plaintiffs point out that "none of the several hundred properties which Chicago has already
    acquired, which are the subject of this case, are involved in [Judge Culliton's case]." (Emphasis
    added.) This fact was fully grasped by the trial court, which found separate grounds (which we
    review below) for granting the section 2--619 motion with respect to properties Chicago has already
    acquired.
    Of course, as noted, the fulfillment of the "same cause" and "same parties" requirements does
    not entail a reflexive dismissal but rather a look at the Hoch factors. Of the four Hoch factors, the
    trial court gave special emphasis to the likelihood of relief in the Culliton proceeding. In seeking
    to upset the trial court's decision, plaintiffs offer surprisingly little argument on the Hoch factors.
    They certainly do not convince us that the factors weigh so heavily against dismissal that the trial
    court's decision was arbitrary, fanciful, or irrational. Plaintiffs' only contention is that "none of the
    equitable relief sought here is involved in [Judge Culliton's case]." Presumably, plaintiffs mean the
    declaratory and injunctive relief they seek here, but they do not present any explanation or develop
    any argument regarding the noninvolvement of this relief in the case before Judge Culliton. We will
    not make their case for them. We hold that the trial court did not abuse its discretion in dismissing,
    under section 2--619(a)(3) of the Code, plaintiffs' request for a declaration that their properties are
    not necessary for the OMP.
    Turning to the trial court's grounds for dismissing count I as it relates to properties other than
    plaintiffs', we note that the trial court appeared to misconstrue count I, though not in a way fatal to
    its analysis. The trial court assumed that all of the property owners other than plaintiffs "contracted"
    with Chicago "for the sale of [their] properties." The source of this assumption is unclear to us.
    Count I alleges that Chicago acquired properties "either through eminent domain proceedings or the
    -49-
    No. 2--08--0769
    threat of eminent domain." (Emphases added.) Count II alleges that "many--indeed hundreds of
    property owners--sold their homes to Chicago under threat of eminent domain in reliance on the truth
    of Chicago's false statements as to necessity to take their properties." (Emphasis added.) Yet count
    II also references condemnation proceedings involving some of the properties.
    A distinction may possibly lie here. The complaint does not expound the phrase "threat of
    eminent domain," but, generally, a "taking" for constitutional purposes requires at least the formal
    initiation of condemnation proceedings. See Kleinschmidt, Inc. v. County of Cook, 
    287 Ill. App. 3d 312
    , 317 (1997) ("where parties agree to compensation so as to forestall a condemnation
    proceeding, no taking occurs"; thus, the takings clause was not triggered where, at the time of the
    sale, the government had not initiated eminent domain proceedings but had passed a resolution
    providing for condemnation in the event the parties did not agree on a purchase price); Towne v.
    Town of Libertyville, 
    190 Ill. App. 3d 563
    , 568 (1989) ("The taking of property in the constitutional
    sense is accomplished only by the filing of a petition, the ascertainment of value, and the payment
    of just compensation"). For the sake of clarity, we treat count I as concerning properties acquired
    in eminent domain proceedings where constitutional strictures applied, and count II as concerning
    properties acquired through voluntary sales where the constitution was not implicated but where
    -50-
    No. 2--08--0769
    common-law principles (such as fraud) of course applied.9 The lynchpin of both counts, however,
    is that the requisite necessity is lacking with respect to properties Chicago has acquired.
    With this clarification in mind, we examine the trial court's specific grounds for dismissing
    the remainder of count I. The trial court reasoned that plaintiffs lack standing to challenge the
    condemnation of properties not their own. Lack of standing may be alleged in a motion pursuant to
    section 2--619(a)(9) of the Code (735 ILCS 5/2--619(a)(9) (West 2006)), which provides for
    dismissal on the ground that "the claim asserted against defendant is barred by other affirmative
    matter avoiding the legal effect of or defeating the claim." We review de novo the dismissal of a
    complaint for lack of standing. Winnebago County Citizens for Controlled Growth v. County of
    Winnebago, 
    383 Ill. App. 3d 735
    , 740 (2008).
    In arguing that they have standing, plaintiffs cite Yusuf and Klaeren. In these cases, the
    plaintiffs were found to have standing to challenge the issuance of special use permits for properties
    adjoining or in the vicinity of theirs. The proposed development in Yusuf was a religious and
    cultural center that would also provide day-care services. The plaintiffs alleged that the development
    "would result in additional traffic and noise at extended hours of the day and night, would have a
    substantial adverse impact upon [their] quiet enjoyment of their property, and would have an adverse
    impact on the value of their property which is near the subject property." Yusuf, 
    120 Ill. App. 3d 9
    Count II does also allege that Chicago made false statements about necessity to "the DuPage
    [sic] County Circuit Court" in condemnation proceedings involving some of the acquired properties.
    Plaintiffs do not, however, allege any reliance by "the DuPage [sic] County Circuit Court" on those
    statements. Count II is reasonably construed, therefore, as concerning transactions outside of
    condemnation proceedings.
    -51-
    No. 2--08--0769
    at 538. The plaintiffs in Klaeren challenged the proposed construction of a retail store near their
    properties, and they alleged that "any increase in noise, traffic or light pollution created by the
    development would affect the use and enjoyment of [their] properties." Klaeren, 
    202 Ill. 2d at 176
    .
    In each case, the court held that the plaintiffs alleged injuries "distinct" from that of the general
    public and therefore could bring their claims. Klaeren, 
    202 Ill. 2d at 176
    ; Yusuf, 120 Ill. App. 3d
    at 538.
    Here, the trial court held, without analysis, that plaintiffs "alleged no such injuries" as were
    claimed in Klaeren and Yusuf. Plaintiffs disagree. They argue that they established standing by
    alleging the following injuries:
    "(A) A portion of [Bensenville] has been turned into a virtual wasteland, which the
    [Residents] are forced to live in or give in to the demands of Chicago;
    (B) Reduction in the value of [the Residents'] properties;
    (C) Decreased tax base in [Bensenville] causing a rise in taxes to those taxpayers
    remaining in the Village; and
    (D) Lack of community on the eastern edge of [Bensenville] surrounding the property
    owned by [the Residents]."
    Plaintiffs argue that these injuries are analogous to those claimed in Klaeren and Yusuf.
    We do not decide whether plaintiffs satisfy the general requirements of standing, because we
    hold that they manifestly fail to meet the specialized and stricter norms for intervention in an eminent
    domain proceeding. Section 10--5--75 of the Eminent Domain Act (735 ILCS 30/10--5--75 (West
    2006)) provides:
    -52-
    No. 2--08--0769
    "Intervening Petition. Any person not made a party may become a party by
    filing an intervening petition setting forth that the petitioner is the owner or has an
    interest in property that will be taken or damaged by the proposed work. The rights
    of the petitioner shall thereupon be fully considered and determined."
    This is a codification of the rule that, "to challenge a taking, one must have a property interest
    affected, and one not alleging a property interest affected has no standing to challenge a taking."
    Lake County Forest Preserve District v. First National Bank of Waukegan, 
    213 Ill. App. 3d 309
    , 314
    (1991). "The entire purpose of the [Eminent Domain Act] is to regulate the rights and duties
    between the condemning authority and those holding property interests. It is designed to protect the
    landowner from the taking of his property without just compensation." City of Crystal Lake v. La
    Salle National Bank, 
    121 Ill. App. 3d 346
    , 355 (1984). To establish standing under the Eminent
    Domain Act, one must allege a property interest that is directly infringed by the taking. See Lake
    County Forest Preserve, 213 Ill. App. 3d at 314 (City of Waukegan had standing to challenge
    proposed taking of property within its boundaries because the city owned a utility easement in the
    subject property; Community Unit School District No. 60, however, could not base standing on the
    prospect of lost revenue because its "interest in receiving tax revenue from the subject property is
    too remote to provide standing to appeal"); City of Crystal Lake, 121 Ill. App. 3d at 355 ("The only
    interest which Crystal Lake can claim is that it has filed a petition seeking to condemn the same
    property previously condemned under which it seeks priority. It is doubtful that this is a property
    right"); Midwest Television, Inc. v. Champaign-Urbana Communications, Inc., 
    37 Ill. App. 3d 926
    ,
    934 (1976) (finding no standing for cable provider to challenge, as effecting a taking without just
    compensation, an ordinance mandating that an easement previously granted to another public utility
    -53-
    No. 2--08--0769
    should, if possible, be interpreted to grant a cable franchisee the same rights in the easement as the
    other public utility; to establish standing, plaintiff would have had to allege "that it is a property
    owner who has granted such an easement to another utility which might be affected"). Plaintiffs
    have not alleged that Chicago's acquisition of other properties in the Acquisition Area directly
    infringed any property interest of their own. They claim only consequential harm.10
    As Chicago points out, plaintiffs would be no better off if they did have standing to challenge
    Chicago's acquisition of the properties, for they are attacking prior judgments that carry preclusive
    effect. Section 2--619(a)(4) of the Code provides for dismissal on the ground "[t]hat the cause of
    action is barred by a prior judgment." 735 ILCS 5/2--619(a)(4) (West 2006). In La Salle National
    Bank v. County Board of School Trustees, 
    61 Ill. 2d 524
     (1975), the supreme court described the
    preclusive effect of a condemnation judgment. In La Salle National Bank, two school boards sought
    to sell land they acquired in separate eminent domain proceedings but later decided not to use for
    the purpose for which it was condemned, i.e., as sites for schools. The plaintiffs, banks that held the
    properties as trustees at the time they were condemned, filed suit to stop the sales, alleging that they
    retained a reversionary interest in the properties that was triggered when the school boards decided
    not to use them for school purposes. The supreme court held that the plaintiffs' claims were barred
    under the doctrine of res judicata:
    "[Plaintiffs] had the opportunity to contend in the eminent domain action that the school
    authorities would take less than a fee simple estate but did not do so. No appeals were taken
    10
    Bensenville may well have easements in some of the Acquisition Area properties it does
    not own in fee simple, but plaintiffs do not distinguish Bensenville's standing from that of the
    Residents.
    -54-
    No. 2--08--0769
    from those final judgments. The judgments are not now subject to collateral attack.
    [Plaintiffs] cannot litigate the question they could have had decided in the original
    proceedings." La Salle National Bank, 
    61 Ill. 2d at 530-31
    .
    Likewise here, plaintiffs, assuming arguendo that they possessed an interest to litigate in the
    condemnation proceedings, cannot revisit the grounds for those prior judgments.
    Counsel for plaintiffs intimated at oral argument that a constitutional violation may consist
    of the very demolition of properties for which the condemning authority has shown no necessity.
    Counsel's insinuation was that, if plaintiffs have no standing to challenge the acquisition of
    properties other than their own, they have standing at least to seek the imposition of a constructive
    trust on those properties in order to forestall what plaintiffs deem an unconstitutional demolition.
    At least in count I, however, plaintiffs allege no illegality of the proposed demolition apart from the
    wrongful taking of the properties. As we have shown, plaintiffs either lack standing to challenge the
    condemnation of properties other than their own or are barred from collaterally attacking those
    condemnation judgments. For the foregoing reasons, we find no error in the trial court's dismissal
    of count I.
    Count IV, which was also dismissed under section 2--619, sought a declaratory judgment that
    the Demolition Ordinance governs demolition of properties in the Acquisition Area. The trial court
    dismissed count IV on the ground that the Act preempts the Demolition Ordinance. "Determination
    of preemption of a local ordinance by a state statute involves construction of the statute and is
    subject to de novo review." City of Champaign v. Sides, 
    349 Ill. App. 3d 293
    , 299 (2004).
    The trial court relied on section 25 of the Act, which provides: "Airport property shall not
    be subject to the laws of any unit of local government except as provided by ordinance of
    -55-
    No. 2--08--0769
    [Chicago]." 620 ILCS 65/25 (West 2006).11 The trial court noted that section 10 of the Act (620
    ILCS 65/10 (West 2006)) defines "airport property" in relevant part as "any property or an interest
    in property that is, or hereafter becomes, part of O'Hare International Airport." The trial court
    concluded that "any property acquired by the City of Chicago for the purposes of the OMP is not
    subject to the Bensenville Demolition Ordinance."
    Plaintiffs' challenge to the trial court's analysis is twofold. First, they contend that "airport
    property" is property legally acquired by Chicago for O'Hare, and, because this very lawsuit
    challenges the legality of Chicago's acquisition of properties in Bensenville, those properties are not
    "airport property." The issue, however, is which legal norms govern the acquisition of property. The
    Act does not attempt to override constitutional restrictions on Chicago's acquisition of property.
    (Plaintiffs' constitutional challenges fail on other grounds, as noted above.) The Act does, however,
    unequivocally override local restrictions on the acquisition of property pursuant to the OMP. Section
    30 of the Act (620 ILCS 65/30 (West 2006)) states:
    "It is declared to be the law of this State *** that the regulation and supervision of
    the City of Chicago's implementation of the [OMP] is an exclusive State function that may
    not be exercised concurrently by any unit of local government."
    "Implementation" we take to encompass all stages of the OMP from property acquisition, to
    demolition, to construction. The Demolition Ordinance, being the creature of a locality, is
    preempted by the Act to the extent that it attempts to regulate any stage in the implementation of the
    OMP.
    11
    There is no question that Chicago has not authorized regulation by any other local
    government.
    -56-
    No. 2--08--0769
    Given the foregoing, we can dispense in short order with plaintiffs' second point, which is
    that the Demolition Ordinance is a public safety measure akin to the police and fire protection that
    Bensenville continues to provide in the Acquisition Area at Chicago's insistence. Plaintiffs wonder
    "how Bensenville can enforce police, fire, and other public safety laws in the Acquisition Area while
    being barred from enforcing its public safety and health[-]based demolition ordinance." But the
    issue, as Chicago notes, is whether Bensenville's police and fire protection and other public safety
    services "constitute attempted regulation of the OMP." Plaintiffs' argument is undercut by the very
    cases they cite, both of which judge a county's obligation to comply with city ordinances by whether
    the ordinances conflict with the statutory program carried out by the county. See Lake County Public
    Building Comm'n v. City of Waukegan, 
    273 Ill. App. 3d 15
    , 20 (1995) (county acting pursuant to
    Public Building Commission Act (50 ILCS 20/1 et seq. (West 1994)) was obligated to comply with
    city building ordinances designed to protect the health and safety of citizens of the city, because there
    was no evidence that the act exempted the county from compliance or that the ordinances would
    thwart the county's operations under the act); Village of Swansea v. County of St. Clair, 
    45 Ill. App. 3d 184
    , 188 (1977) (county acting pursuant to Animal Control Act (Ill. Rev. Stat. 1975, ch. 8, par.
    351 et seq.) not obligated to comply with city zoning ordinances that "frustrate" the aim of the act).
    Plaintiffs point to no way in which Bensenville's provision of fire and police services attempts to
    regulate the implementation of the OMP. Here lies the difference between those measures and the
    Demolition Ordinance, which overtly purports to restrict the demolition of properties in the
    Acquisition Area. We uphold the dismissal of count IV on the ground that the Demolition Ordinance
    is preempted by the Act.
    II. Dismissal of Counts II and III
    -57-
    No. 2--08--0769
    The trial court dismissed counts II and III pursuant to section 2--615 of the Code. The
    following standards shape our review of dismissals under section 2--615.
    "The question presented by a section 2--615 motion to dismiss is whether the
    allegations of the complaint, when viewed in a light most favorable to the plaintiff, are
    sufficient to state a cause of action upon which relief can be granted. [Citation.] Illinois is
    a fact-pleading jurisdiction that requires a plaintiff to present a legally and factually sufficient
    complaint. [Citation.] The plaintiff is not required to prove his or her case, but must allege
    sufficient facts to state all the elements of the asserted cause of action. [Citation.]
    When ruling on a section 2--615 motion to dismiss, the trial court should admit all
    well-pleaded facts as true and disregard legal and factual conclusions that are unsupported
    by allegations of fact. [Citation.] If, after disregarding any legal and factual conclusions, the
    complaint does not allege sufficient facts to state a cause of action, the trial court must grant
    the motion to dismiss. [Citation.] The standard of review on a section 2--615 motion to
    dismiss is de novo." Neurosurgery & Spine Surgery, S.C. v. Goldman, 
    339 Ill. App. 3d 177
    ,
    182 (2003).
    Count II alleges common-law fraud. As noted above, we construe count II as concerning
    alleged misrepresentations by Chicago in the course of voluntary transactions between Chicago and
    property owners other than plaintiffs. "The elements of common-law fraud are: (1) a false statement
    of material fact; (2) defendant's knowledge that the statement was false; (3) defendant's intent that
    the statement induce plaintiff to act; (4) plaintiff's reliance upon the truth of the statement; and (5)
    plaintiff's damages resulting from reliance on the statement." Wernikoff v. Health Care Service
    Corp., 
    376 Ill. App. 3d 228
    , 233 (2007). Corresponding to these elements, plaintiffs allege, in
    -58-
    No. 2--08--0769
    relevant part: (1) Chicago made false allegations "to meet the necessity requirements of the Illinois
    Constitution," namely, that all of the properties in the Acquisition Area are needed for Phase 1 or
    Phase 2 of the OMP; (2) "Chicago [knew] that its factual assertions [were] false; (3) Chicago
    "intended its false factual statements as to necessity would cause many property owners to sell their
    homes and businesses under threat of eminent domain"; (4) "hundreds of property owners *** sold
    their homes to Chicago under threat of eminent domain in reliance on the truth of Chicago's false
    statements as to necessity to take their properties"; and (5) plaintiffs have suffered "a lack of
    community," diminished property values, and higher property taxes.
    The trial court dismissed count II upon finding that: (1) the alleged representations are not
    actionable both because they constitute legal positions rather than assertions of fact and because they
    amount to "[a]ssurance[s] as to future events"; and (2) plaintiffs' damages are "speculative at best."
    In addition to defending these grounds, Chicago argues that count II fails because plaintiffs
    seek to recover based on statements made to and relied on by third parties (i.e., other property
    owners), not plaintiffs themselves. Chicago made this argument below but the trial court did not
    comment on it. We, however, may consider it as a basis for affirmance. Paul H. Schwendener, Inc.
    v. Jupiter Electric Co., 
    358 Ill. App. 3d 65
    , 71 (2005) (dismissal under section 2--615 may be
    affirmed on any basis in the record).
    We rely on principles laid out in Shannon v. Boise Cascade Corp., 
    208 Ill. 2d 517
     (2004).
    The plaintiffs in Shannon brought a claim under the Consumer Fraud and Deceptive Business
    Practices Act (Consumer Fraud Act) (815 ILCS 505/1 et seq. (West 1998)) against Boise Cascade,
    the manufacturer of siding that was installed on the plaintiffs' homes when they were built. The
    plaintiffs alleged that the siding deteriorated prematurely and that Boise Cascade made false
    -59-
    No. 2--08--0769
    representations about the durability of the siding in its product literature. The supreme court
    affirmed the trial court's grant of summary judgment for Boise Cascade. The court held that
    "deceptive advertising cannot be the proximate cause of damages under the [Consumer Fraud] Act
    unless it actually deceives the plaintiff" and that the plaintiffs' complaint was deficient for failing to
    allege such "actual deception." Shannon, 
    208 Ill. 2d at 525
    . The court caveated that the deception
    need not "always be direct between the defendant and the plaintiff" to satisfy the Consumer Fraud
    Act. Shannon, 
    208 Ill. 2d at 526
    . That is, the complaint would have been sufficient if the plaintiffs
    had alleged that the literature for the siding deceived a builder, architect, or contractor resulting in
    installation of the siding on the plaintiffs' homes. "In those circumstances, the purchaser, who may
    have no independent knowledge of the qualities or expected performance standards of siding, is
    deceived because of the deception of the builder, architect or contractor, who reasonably should have
    had correct knowledge." Shannon, 
    208 Ill. 2d at 526
    . The plaintiffs, however, did not "allege that
    any deceptive advertising by [Boise Cascade] was received by any plaintiff, or that it was received
    by any builder, architect, engineer, or other like person somehow connected with a plaintiff."
    (Emphasis added.) Boise Cascade, 
    208 Ill. 2d at 525
    . The plaintiffs' fraud claim thus failed. Boise
    Cascade, 
    208 Ill. 2d at 526
    .
    As support for its reasoning, the supreme court cited St. Joseph Hospital v. Corbetta
    Construction Co., 
    21 Ill. App. 3d 925
     (1974), where a hospital brought a common-law fraud claim
    against the manufacturer of wall paneling installed in the hospital. The hospital put forth evidence
    at trial that the manufacturer failed to disclose to the architect and the builder that product testing
    had revealed the paneling to have a flame spread in excess of that allowed by the Chicago building
    code. The appellate court upheld a jury verdict in favor of the hospital. St. Joseph, 21 Ill. App. 3d
    -60-
    No. 2--08--0769
    at 957. The court held that there was sufficient evidence of reliance because the hospital could be
    said to have been deceived through the manufacturer's deception of the architect and the builder. St.
    Joseph, 21 Ill. App. 3d at 956. The court explained that privity "in the traditional sense" does not
    apply in fraud cases. St. Joseph, 21 Ill. App. 3d at 954. "It is enough," the court explained, "that the
    statements by the defendant be made with the intention that it reach the plaintiff and influence his
    action and that it does reach him and that he does rely upon it, to his damage." St. Joseph, 21 Ill.
    App. 3d at 954. The court cited legal commentary for support. See St. Joseph, 21 Ill. App. 3d at 955
    (" 'While some connection, direct or indirect, between a party charged with making false
    representations and a party relying thereon must be shown, it is not essential, in support of a cause
    of action for damages resulting from false representations, that the false representations be shown
    to have been made directly to the party claiming to have relied upon them' "), quoting 37 Am. Jur.
    2d Fraud & Deceit §190, at 252-53 (1968).
    The suit in Boise Cascade was brought under the Consumer Fraud Act, but the supreme court
    cited with unqualified approval St. Joseph's requirement of actual deception in common-law fraud
    cases as well. Count II fails this requirement of actual deception. The claimed misrepresentations
    were made to third parties--other property owners--and there is no allegation that these
    misrepresentations flowed to plaintiffs and influenced their actions. Plaintiffs allege no reliance of
    their own and so fail to plead common-law fraud under Illinois law. See Premier Electrical
    Construction Co. v. Morse/Diesel, Inc., 
    257 Ill. App. 3d 445
    , 458 (1993) ("a common law fraud
    claim requires actual reliance, which means that the misrepresentations must reach the plaintiff, who
    must reasonably rely on them").

    Plaintiffs are correct that Board of Education of the City of Chicago v. A, C & S, Inc., 
    131 Ill. 2d 428
     (1989), allows a plaintiff to recover for damages caused strictly by a third party's reliance
    on a defendant's misrepresentations, but plaintiffs overstate the scope of this liability. The plaintiffs
    in A, C & S sued manufacturers and suppliers of asbestos and alleged that the defendants made
    negligent misrepresentations about that product. The defendants argued that the trial court's
    dismissal of the negligent misrepresentation claim was proper under Moorman Manufacturing Co.
    v. National Tank Co., 
    91 Ill. 2d 69
    , 88-89 (1982), which held that "economic loss is recoverable
    where one intentionally makes false representations [citation], and where one who is in the business
    of supplying information for the guidance of others in their business transactions makes negligent
    representations." The defendants noted that the plaintiffs made no allegation that the defendants
    were in the business of supplying information for the guidance of others in their business
    transactions. The supreme court held that it need not resolve "the question of when and against
    whom a plaintiff may recover economic losses for negligent misrepresentation" (emphasis added)
    because the plaintiffs alleged not just economic loss but physical harm as well. A, C & S, 
    131 Ill. 2d at 454
    . The court found a more apt standard in section 311 of the Restatement (Second) of Torts,
    entitled "Negligent Misrepresentation Involving Risk of Physical Harm." Restatement (Second) of
    Torts §311 (1965). Section 311 declares:
    "(1) One who negligently gives false information to another is subject to liability for
    physical harm caused by action taken by the other in reasonable reliance upon such
    information, where such harm results
    (a) to the other, or
    -62-
    No. 2--08--0769
    (b) to such third persons as the actor should expect to be put in peril by the
    action taken." Restatement (Second) of Torts §311, at 106 (1965).
    The court observed that section 311 creates "broader liability" than section 552 of the Restatement,
    entitled "Information Negligently Supplied for the Guidance of Others," which requires, in part, that
    the defendant make the representations "in the course of his business." Restatement (Second) of
    Torts §552, at 126 (1965).12
    Plaintiffs argue that, in adopting section 311, the supreme court in A, C & S implicitly
    adopted its companion provision, section 310, which is entitled "Conscious Misrepresentation
    Involving Risk of Physical Harm" and concerns fraudulent rather than negligent misrepresentations.
    Section 310 provides:
    "An actor who makes a misrepresentation is subject to liability to another for physical
    harm which results from an act done by the other or a third person in reliance upon the truth
    of the representation, if the actor
    12
    Section 311 is broader also because, as we explain below, it permits recovery for parties
    who did not themselves rely on the alleged misrepresentations but were damaged by those who did.
    The supreme court in A, C & S did not, however, apply this feature of section 311. In remanding
    the case, the court noted that the plaintiffs' allegations were "very broad and unspecific" and that they
    would need to prove at trial "what representations were made to them and who made [the]
    representations." (Emphasis added.) A, C & S, 
    131 Ill. 2d at 456
    . Apparently, the plaintiffs alleged
    their own reliance, not that of others. Thus, the court relied on section 311 not for its expansive
    concept of reliance but for its lack of a requirement that the defendant have made the
    misrepresentation in the course of its business.
    -63-
    No. 2--08--0769
    (a) intends his statement to induce or should realize that it is likely to induce
    action by the other, or a third person, which involves an unreasonable risk of physical
    harm to the other, and
    (b) knows
    (I) that the statement is false, or
    (ii) that he has not the knowledge he professes." Restatement
    (Second) of Torts §310, at 103 (1965).
    Section 310 imposes liability on the defendant for physical harm to another "which results from an
    act done by the other or a third person in reliance" upon a conscious misrepresentation made by the
    defendant. (Emphasis added.) Restatement (Second) of Torts §310, at 103 (1965). Likewise,
    section 311 imposes liability where the defendant makes a negligent misrepresentation to another
    and the other's reliance causes physical harm to "third persons." Restatement (Second) of Torts
    §311, at 106 (1965). Thus, sections 310 and 311 both permit recovery for parties who did not
    themselves rely on the alleged misrepresentation but were damaged by those who did so rely.
    Neither section is applicable here, however, because each presupposes physical harm and plaintiffs
    have not alleged that they incurred such harm.
    Because plaintiffs have not alleged that they themselves relied on the misrepresentations for
    which they seek recovery, and because they do not claim physical harm, they have not adequately
    pleaded the element of reliance. The trial court, therefore, did not err in dismissing count II. In light
    of this holding, we do not review Chicago's other proposed bases for affirming the dismissal.
    Count III of plaintiffs' second amended complaint alleges unjust enrichment. Plaintiffs allege
    that "Chicago has improperly and unjustly obtained and continue[s] to retain the use of the properties
    -64-
    No. 2--08--0769
    in the Acquisition Area by violating the necessity limits of the Illinois Constitution and by false
    statements as to necessity." The trial court dismissed count III because: (1) the properties "are not
    for the benefit of the City of Chicago," that is, there is no indication that Chicago "intends to use the
    acquired properties for anything other than expansion of O'Hare"; and (2) Chicago acquired the
    properties through real estate contracts, and, therefore, unjust enrichment, a quasi-contractual
    remedy, is not available.
    Chicago reiterates here an argument that it presented below but that drew no comment from
    the trial court. Nonetheless, the argument may serve as a basis for affirmance. See Paul H.
    Schwendener, Inc., 358 Ill. App. 3d at 71. Chicago notes that count III deals strictly with Chicago's
    acquisition of properties other than plaintiffs'. Count III is deficient, Chicago suggests, because it
    does not allege that Chicago accepted any benefit from plaintiffs. This does not quite identify the
    true problem with count III. It is not itself fatal to count III that plaintiffs are complaining about what
    Chicago acquired from others. "To state a cause of action based on a theory of unjust enrichment,
    a plaintiff must allege that the defendant has unjustly retained a benefit to the plaintiff's detriment,
    and that defendant's retention of the benefit violates the fundamental principles of justice, equity, and
    good conscience." HPI Health Care Services, Inc. v. Mt. Vernon Hospital, Inc., 
    131 Ill. 2d 145
    , 160
    (1989). The doctrine of unjust enrichment permits "recovery of a benefit that was transferred to the
    defendant by a third party." (Emphasis added.) HPI Health Care Services, 131 Ill. 2d at 161. The
    defendant's retention of a benefit transferred to it by a third party would be unjust where: "(1) the
    benefit should have been given to the plaintiff, but the third party mistakenly gave it to the defendant
    instead [citation], (2) the defendant procured the benefit from the third party through some type of
    wrongful conduct [citation], or (3) the plaintiff for some other reason had a better claim to the benefit
    -65-
    No. 2--08--0769
    than the defendant [citation]." HPI Health Care Services, 131 Ill. 2d at 161-62. From these
    propositions it is apparent that the real flaw in plaintiffs' claim is their failure to allege how Chicago's
    acquisition of the properties from the other owners deprived plaintiffs of any "benefit." Plaintiffs
    claim damages flowing from Chicago's acquisition of the properties, but the basis of their complaint
    is not that the properties should have been conveyed to them instead. Plaintiffs assert no legal or
    equitable interest in the properties themselves, and therefore we cannot discern what "benefit"
    plaintiffs claim was wrongfully intercepted by Chicago when it acquired the properties. Cf. Harper
    v. Adametz, 
    142 Conn. 218
    , 225, 
    113 A.2d 136
    , 139 (1955) (real estate agent unjustly enriched when
    he suppressed his client's purchase offer and acquired the property for himself). As plaintiffs have
    not alleged that Chicago is retaining a "benefit" to their detriment, we hold that the trial court
    properly dismissed count III of plaintiffs' second amended complaint.
    For the foregoing reasons, we affirm the dismissal with prejudice of counts I through IV of
    plaintiffs' second amended complaint.
    II. The Preliminary Injunction Hearing
    Plaintiffs argue that the trial court erred in dissolving its preliminary injunction against
    demolition of properties in the Acquisition Area. To obtain a preliminary injunction, the movant
    must establish:
    "(1) that he or she possesses a clearly ascertainable right which needs protection; (2)
    that he or she would suffer irreparable harm without the injunction; (3) there is no adequate
    remedy at law for his [or her] injury; (4) there is a likelihood of success on the merits; and
    (5) the plaintiff will suffer more harm without the injunction than the defendant will suffer
    with it. ***
    -66-
    No. 2--08--0769
    ***
    *** In balancing these equities, the court should also consider the effect of the
    injunction on the public." Grandberg, 279 Ill. App. 3d at 888-90.
    "The decision to grant or deny a preliminary injunction lies within the sound discretion of the trial
    court and on review the decision will not be disturbed absent an abuse of discretion." Klaeren, 
    202 Ill. 2d at 177
    .
    Plaintiffs claim that the trial court abused its discretion by "abdicat[ing] *** its common law
    public nuisance jurisdiction in favor of non-existent administrative agency protection." Plaintiffs
    assert that the trial court erroneously assumed that "the judiciary either did not have independent
    nuisance jurisdiction, or that the trial court should somehow defer to the administrative agencies."
    Plaintiffs claim that these misapprehensions are evident in several of the trial court's remarks. For
    example, in the prefatory findings in its written order, the trial court led with this statement:
    "I now see that there are sufficient governmental agencies and regulations that can oversee
    this demolition project. In my opinion any further oversight by the Court would be done
    without proper authority."
    The trial court determined that the "enforcement division[s]" of these "agencies" are adequate to
    redress "violations of regulations, codes[,] or the like." The trial court found it "appropriate for
    demolition to commence now under the standards laid out by the expert testimony of the City of
    Chicago" and that the court "[did not] have a basis to impose any further guidelines." The trial court
    concluded its general findings by stating that "there is a separate remedy with the enforcement
    divisions of the various environmental protection agencies that would not require judicial
    intervention."
    -67-
    No. 2--08--0769
    As plaintiffs note, these thoughts surfaced again in the trial court's specific findings. In
    considering whether plaintiffs had an adequate remedy at law, the court determined:
    "If Plaintiffs had established their allegations that [Chicago's] demolition will
    endanger the public health, the Plaintiffs would likely have no adequate remedy at law. But,
    as indicated above, Plaintiffs have failed to do so, and consequently, the Court cannot grant
    the continuing preliminary injunctive relief which Plaintiffs seek.
    A separate remedy does exist with the enforcement divisions of various federal and
    state environmental protection agencies as created by legislative bodies. There is no further
    authority or basis for judicial intervention by this court."
    We agree with plaintiffs that the trial court's remarks are questionable on several levels.
    First, they are not consistent. At one point, the court claims that these "agencies" (unnamed but for
    the "EPA") can "oversee" the demolition, which suggests active supervision. At another point, the
    court remarks that the agencies are available for redressing violations of regulations and codes,
    which implies not ongoing or active oversight but rather intervention as needed. Second, there is
    scant evidentiary ground for finding any administrative agency available to oversee the demolition
    in a manner active and thorough enough to prevent a public nuisance and so to serve as an adequate
    alternative to the equitable relief sought by plaintiffs, namely, a prospective injunction. The
    testimony at the July 2008 hearing contains but two allusions to potential agency involvement. The
    first is the October 31, 1997, "No Further Remediation" in which the IEPA implies that further soil
    disturbance at the Nelson Wire/Pro Logis site will lead to action by the IEPA, and the second is
    Blickle's testimony that the USEPA and IEPA both must be informed of the presence of RACM in
    -68-
    No. 2--08--0769
    the Acquisition Area. These two points of evidence do not establish potential agency involvement
    nearly on the scale the court conceived.
    Following oral argument, Chicago filed a motion to cite statutes and regulations that vest the
    IEPA and the USEPA with power to enforce environmental laws and regulations. Chicago notes,
    for instance, that the Illinois Environmental Protection Act (Environmental Protection Act) (415
    ILCS 5/31(d)(1) (West 2006)) provides that "[a]ny person may file with the [Illinois Pollution
    Control] Board a complaint *** against any person allegedly violating this Act, any rule or
    regulation adopted under [this] Act, any permit or term or condition of a permit, or any Board order."
    The Environmental Protection Act also permits the State to file enforcement actions in the circuit
    courts. See generally 415 ILCS 5/42, 43, 44 (West 2006). We grant this motion, but note that these
    various authorities do not persuade us that the trial court acted correctly. Agency authority does not
    displace the judiciary's equitable powers in these circumstances.
    Such is the lesson of Village of Wilsonville v. SCA Services, Inc., 
    77 Ill. App. 3d 618
     (1979),
    where a municipality and a county sued to enjoin the operation of a newly operational landfill for
    hazardous waste. The plaintiffs argued that the landfill was a public nuisance because there was a
    risk that toxic or flammable substances would seep from the landfill. The IEPA had issued the
    defendant an initial permit to operate the landfill, and afterward the defendant applied for and
    received from the IEPA a permit for each waste the defendant proposed to deposit at the landfill.
    The trial court entered a permanent injunction against continued operation of the landfill.
    Wilsonville, 77 Ill. App. 3d at 621-23.
    The defendant appealed, and the court permitted the USEPA to file an amicus curiae brief
    in which it defended the public need for the landfill. The defendant argued to the court "that the trial
    -69-
    No. 2--08--0769
    court either lacked jurisdiction to hear the case or, in the alternative, should have deferred to the
    concurrent jurisdiction of the administrative agencies, IEPA and the Pollution Control Board."
    Wilsonville, 77 Ill. App. 3d at 623. The court rejected both positions while acknowledging "the lack
    of expertise in courts to fully understand the complicated technical matters involved in a case of this
    nature." Wilsonville, 77 Ill. App. 3d at 625. The court found that Illinois law "clearly indicate[s]
    a policy *** not to leave the enforcement of environmental matters exclusively in the hands of
    administrative agencies but to have a dual system of enforcement and civil relief." Wilsonville, 77
    Ill. App. 3d at 625; see also People ex rel. Scott v. Janson, 
    57 Ill. 2d 451
    , 460 (1974) ("there exists
    jurisdiction [in the courts] to abate public nuisances which may endanger the general welfare").
    Proceeding to the merits of the case, the appellate court upheld the permanent injunction.
    The defendant acknowledged that "severe damage [was] likely to result if substantial amounts of
    hazardous substances escaped from the landfill," but argued that the possibility of a release was "too
    uncertain and, in any event, too far in the distant future to form the basis for the issuance of an
    injunction." Wilsonville, 77 Ill. App. 3d at 633. The court disagreed, holding that the "extremely
    serious," indeed "catastrophic," nature of the possible harm outweighed the consideration of
    likelihood. Wilsonville, 77 Ill. App. 3d at 635, 638.
    On appeal to the supreme court, the defendant argued for deference to the IEPA, which had
    licensed the landfill, and to the USEPA, which had filed the amicus brief explaining the public need
    for the landfill. The court declined to defer:
    "The defendant *** asserts that error occurred in the courts below when they failed
    to defer to the IEPA and the USEPA, as well as when they failed to give weight to the
    permits issued by the IEPA. This assertion has no merit, however, because the data relied
    -70-
    No. 2--08--0769
    upon by the IEPA in deciding to issue a permit to the defendant were data collected by the
    defendant, data which have been proved at trial to be inaccurate. In particular, defendant's
    experts concluded that any subsidence at the site would be negligible. The IEPA (as well as
    the USEPA) adopted this inaccurate conclusion in deciding to issue a permit to the
    defendant." Village of Wilsonville v. SCA Services, Inc., 
    86 Ill. 2d 1
    , 27 (1981).
    Reaching the merits, the supreme court upheld the permanent injunction. The court agreed
    with the trial and appellate courts that "a prospective nuisance is a fit candidate for injunctive relief."
    (Emphasis in original.) Wilsonville, 
    86 Ill. 2d at 25
    . The court held that "the defendant is engaged
    in an extremely hazardous undertaking at an unsuitable location, which seriously and imminently
    poses a threat to the public health." Wilsonville, 
    86 Ill. 2d at 30
    . The court rejected the defendant's
    contention that the plaintiffs had an adequate remedy at law because they could have pursued relief
    through administrative channels:
    "We *** disagree with the defendant that since the plaintiffs could seek review from
    the IEPA's decision to grant permits to the defendants through the Pollution Control Board
    they have an adequate remedy at law and are unable to obtain relief in a court of equity.
    First, the plaintiffs are not seeking a review of the issuance of permits. The plaintiffs [are
    seeking] to enjoin a nuisance, a matter which is properly brought in a court of equity. This
    court has stated that jurisdiction exists in the circuit court 'to abate public nuisances which
    may endanger the general welfare.' [Citation.] Thus, the trial court has subject matter
    jurisdiction to decide the issues raised herein, and to award appropriate equitable relief."
    Wilsonville, 86 Ill. 2d at 27-28.
    -71-
    No. 2--08--0769
    From Wilsonville we see the error in the trial court's reasoning behind its termination of the
    preliminary injunction. Like Wilsonville, this case is an "environmental matter[]" (Wilsonville, 77
    Ill. App. 3d at 625) in which a proposed activity is claimed to threaten a public nuisance in the form
    of release of hazardous substances into residential areas. Jurisdiction is no less certain here than in
    Wilsonville. Having jurisdiction, the trial court had a responsibility to determine, under all relevant
    factors, and without regard to the concurrent jurisdiction of administrative agencies, whether
    demolition would constitute a public nuisance. The court, however, displayed an overt reliance on
    the powers of administrative agencies in determining whether plaintiffs have an adequate remedy
    at law. The court found that "a separate remedy does exist with the enforcement divisions of various
    federal and state environmental protection agencies as created by the legislative bodies." This
    reliance was misplaced for two reasons. First, it was wrong from an evidentiary point of view
    because, as noted, the record contains virtually no evidence of any potential agency involvement.
    See Liebert Corp. v. Mazur, 
    357 Ill. App. 3d 265
    , 276 (2005) (a trial court abuses its discretion when
    it relies on a factual finding that is against the manifest weight of the evidence, i.e., where the
    opposite conclusion is clearly evident). Second, it was wrong from an institutional view--that is, as
    a matter of law--because, as Wilsonville teaches, the court had no cause to abdicate its judicial
    function even if a remedy could be found in administrative bodies. See Engel v. Loyfman, 
    383 Ill. App. 3d 191
    , 197 (2008) (a trial court abuses its discretion when its decision is based on a
    "misapprehension of law"). In Wilsonville, the supreme court rejected the defendant's argument that
    the plaintiffs had an adequate remedy at law because they could have pursued administrative review
    of the IEPA's decision to license the defendant's landfill. The supreme court reasoned that the
    plaintiffs were seeking "to enjoin a nuisance, a matter which is properly brought in a court of equity."
    -72-
    No. 2--08--0769
    Wilsonville, 86 Ill. 2d at 27. In Wilsonville, there at least was an identifiable remedy available
    through administrative channels. Here, by contrast, there was no evidence of any available remedy,
    much less one comparable to the injunction sought. The trial court, we conclude, abused its
    discretion in finding that plaintiffs have an adequate remedy at law.
    We recognize, of course, that the trial court's discussion of the "adequate remedy at law"
    factor appears at first blush to have alternative rationales. Immediately preceding the reference to
    administrative agencies, the court stated:
    "If Plaintiffs had established their allegations that the City's demolition will endanger public
    health, the Plaintiffs would likely have no adequate remedy at law. But, as indicated above,
    Plaintiffs have failed to do so, and consequently, the Court cannot grant the continuing
    preliminary injunctive relief which Plaintiffs seek."
    In actuality, this was not a finding that plaintiffs have an adequate remedy at law but rather an
    explanation for not reaching the issue in light of the court's findings on other factors. In that respect,
    it does not jibe with the court's immediately following remark about the availability of remedies from
    administrative agencies.
    We also recognize that plaintiffs were obligated to satisfy all prerequisites for a preliminary
    injunction. In theory, then, our disagreement with the trial court's finding that plaintiffs have an
    adequate remedy at law would pose no barrier to affirmance should we determine that plaintiffs
    failed to meet one or more of the other prerequisites. We decline to take that avenue, since it is clear
    that the trial court's entire analysis was influenced by its factually unfounded and legally erroneous
    view of the potential role of administrative agencies in the demolition. Although the trial court's
    erroneous perspective does not overtly surface in its discussion of the remaining findings, the general
    -73-
    No. 2--08--0769
    discussion that precedes its specific findings is pervaded with a sentiment that the court had no place
    adjudicating matters on which administrative agencies may act. No fewer than five times does the
    court mention "administrative agencies" and their "enforcement divisions." In fact, the court's
    discussion is bookended by two of these references. At the outset of its remarks, before even hinting
    at its own assessment of the alleged hazards in the proposed demolition, the court mentions that
    "there are sufficient governmental agencies and regulations that can oversee this demolition project"
    and that "further oversight by the Court would be done without proper authority." The court
    concludes its remarks by stating: "Based on the foregoing[,] there is a separate remedy with the
    enforcement divisions of the various environmental protection agencies that would not require
    judicial intervention." This is revealing, for, though the availability of another remedy is but one of
    multiple considerations in weighing the propriety of injunctive relief, the court gives it exclusive
    attention here. Tellingly, the court's discussion ends not with an assertion of its own jurisdiction but
    with an attitude of deference.
    A further sign that the trial court's entire analysis was influenced by its notion of agency
    involvement is its failure to resolve the core conflicts in the testimony at the hearing. We have
    exhaustively set forth the evidence and find it teeming with polarized expert opinions on highly
    technical matters such as soil sampling, soil screening levels, emission factors, and demolition
    controls. The trial court made some reference to this testimony but its analysis shows no weighting
    of these radically opposed views. There is instead this summary finding:
    "[N]ot only will proper precautionary measures be taken during demolition through the
    application of CRA's decommissioning and demolition controls *** and air monitoring
    program *** to prevent any unsafe exposure to any potentially harmful materials in the
    -74-
    No. 2--08--0769
    Acquisition Area, but Plaintiffs' claims that the Acquisition Area presents significant
    uncontrollable risks to public health are simply without foundation."
    Section 11--101 of the Code (735 ILCS 5/11–101 (West 2006)) provides that every order granting
    or denying an injunction "shall set forth the reasons for its entry." Section 11--101 requires reasons
    clear and detailed enough to apprize the reviewing court of the basis for the decision. See In re
    Marriage of Grauer, 
    133 Ill. App. 3d 1019
    , 1026 (1985).13 The trial court's reasoning does not
    contain specific enough findings based on proper considerations to allay our concern that the court
    diminished its judicial function by impermissibly deferring to what it perceived as the capability of
    administrative bodies to police the demolition. "A court commits error when it fails to exercise its
    discretion due to a belief that it has no discretion to exercise." RTS Plumbing Co. v. DeFazio, 
    180 Ill. App. 3d 1037
    , 1041 (1989). We therefore reverse the trial court's order terminating the
    13
    At oral argument, Chicago claimed that the trial court's findings of fact are "extensive" and
    that the court's reference to the authority of administrative agencies over the demolition was not the
    "basis" of its decision but rather a "prefatory" or "background" observation. Chicago was then asked
    where in its appellee's brief it argued that the trial court properly resolved the conflicting testimony
    at the injunction hearing. Counsel at the podium was given the opportunity to confer with co-
    counsel on the question. Chicago mentioned the possibility of also submitting a written response.
    After counsel's conference, Chicago was unable to identify where in its brief it defended the formal
    sufficiency of the trial court's findings. Moreover, Chicago has since filed only a motion to cite
    various statutes and regulations, which motion we addressed above. Consequently, Chicago has
    effectively abandoned any effort to defend the trial court's findings as formally sufficient under
    section 11--101.

    remedies available from administrative agencies and, more importantly, our holding, pursuant to
    Wilsonville, that any such remedies cannot replace judicial remedies in cases of this nature.
    Last, we dispose of plaintiffs' "motion to cite additional authority." Plaintiffs seek to apprize
    us that (1) the USEPA has heightened its standards for airborne lead emissions, and (2) certain
    airlines operating out of O'Hare have voiced opposition to Phase 2 of the OMP. These matters are
    more in the nature of additional evidence than additional authority. We deny the motion without
    prejudice to plaintiffs seeking to raise these matters before the trial court on remand.
    III. Conclusion
    For the foregoing reasons, we affirm the trial court's judgment dismissing counts I through
    IV of plaintiffs' second amended complaint. We reverse, however, the judgment terminating the
    preliminary injunction that was entered in July 2007, and we remand for further proceedings
    consistent with this opinion.
    Affirmed in part and reversed in part; cause remanded with directions.
    ZENOFF, P.J., and GROMETER, J., concur.
