    Before VAUGHN, TRAYNOR, and MONTGOMERY-REEVES, Justices.
    Upon appeal from the Superior Court. AFFIRMED IN PART, REVERSED IN PART.
    Eric J. Monzo, Esquire, MORRIS JAMES LLP, Wilmington, Delaware; for Appellants Eric
    Monzo and Dana Spring Monzo.
    Louis J. Rizzo, Jr., Esquire, REGER RIZZO & DARNALL LLP, Wilmington, Delaware;
    for Appellee Nationwide Property & Casualty Insurance Company.
    MONTGOMERY-REEVES, Justice:
    This appeal relates to an insurance coverage dispute.          In 2011, Appellants
    Eric J. Monzo and Dana Spring Monzo purchased a homeowners insurance policy issued
    by Appellee, Nationwide Property & Casualty Co. (“Nationwide”). The policy contained
    standard exclusions for water damage and earth movement, along with optional water
    backup coverage.
    In July 2017, a heavy thunderstorm destroyed a pedestrian bridge and retaining wall
    located at the Monzos’ residence. A pair of engineering reports prepared after the storm
    indicated that a combination of water backups from drainage systems, scouring of supporting
    earth embankments, heavy rain, and tree debris caused the damage. The Monzos filed a
    claim with Nationwide, seeking coverage under the homeowners insurance policy.
    Nationwide denied coverage, and the Monzos filed suit in the Superior Court. The
    court granted summary judgment for Nationwide, holding that the policy’s earth movement
    and water damage exclusions applied. The Monzos appealed, arguing that the Superior
    Court erred by granting summary judgment too early in the discovery process,
    misinterpreting the policy, and denying a motion for post-judgment relief.
    Having reviewed the briefs and record on appeal, the Court: (i) affirms the Superior
    Court’s holding that Nationwide was entitled to summary judgment regarding the collapsed
    bridge; (ii) reverses the Superior Court’s holding that Nationwide was entitled to summary
    2
    judgment regarding the retaining wall; and (iii) affirms the Superior Court’s denial of the
    Monzos’ post-judgment motion.
    I.     RELEVANT FACTS AND PROCEDURAL BACKGROUND
    A.     The Monzos Purchase Homeowners Insurance from Nationwide
    In July 2011, the Monzos approached Matthew Papa, an insurance agent, about
    purchasing comprehensive insurance coverage from Nationwide.1 The Monzos expressed
    interest in several different types of coverage, including a homeowners insurance policy
    covering the couple’s residence in Greenville, Delaware.2
    As part of the underwriting process, Nationwide hired Cornerstone Appraisal
    Services Inc. (“Cornerstone”) to inspect the Greenville residence and provide a risk analysis.3
    Cornerstone drafted a report describing various aspects of the property, including two
    pedestrian bridges crossing a stream.4 After receiving Cornerstone’s report, Nationwide
    required that the Monzos comply with various conditions, such as providing an alarm
    certification and installing a fireplace screen.5 Nationwide also required that the Monzos
    sign a document acknowledging that they did not purchase flood insurance.6 The top of the

    A144. The document asked the policyholder to acknowledge, “I understand that loss resulting
    from flood damage is not covered under my homeowners’ policy, and that flood coverage is
    available through the National Flood Insurance Program (NFIP). By signing this form, I am
    voluntarily choosing not to purchase flood protection for my building and/or contents under a
    National Flood Insurance policy as indicated below.” Id.

    acknowledgment stated, “Everyone lives in a flood zone—it is just a question of whether
    you live in a low, moderate, or high risk area. Nearly 25% of all flood claims are for
    properties located in lower-risk flood areas or those property locations where flooding is not
    expected.”7
    Eric Monzo signed the acknowledgment.8 Nonetheless, it was his “understanding
    that this election applied only to the buildings located at the property and related contents
    . . . . [Eric] did not agree to waive purchase of [flood] coverage as it related to other structures
    located at the property . . . .”9
    In August 2011, Nationwide accepted the Monzos’ application and issued a
    homeowners insurance policy covering the Greenville property.10 The final policy included
    “Option R Broad Water Backup of Sewers or Drains Coverage” (“Option R Coverage”), for
    which the Monzos paid extra premiums.11 The Monzos specifically negotiated that
    Option R Coverage would apply to several water drainage systems on their lot, including:
    (i) an underground septic system that drains into a leach field; (ii) a sump pump system that
    removes water from the residence’s foundation, draining into the stream; (iii) a water system

    connected to a well; and (iv) a system of gutters that carries water from the residence’s roof
    to the stream.12
    B.     The Monzos File a Claim with Nationwide after a Storm Damages their
    Greenville Residence
    On July 23, 2017, a heavy thunderstorm struck the Monzos’ residence.13 After
    hearing the “septic tank backup alarm,” Eric Monzo “went downstairs” to silence the alarm,
    “found water in the basement area,” and “spent the remainder of the evening and early
    morning cleaning, clearing, and removing the water that had seeped from the ground through
    the walls and floor,” along with “flood or wastewater” that had “backed up” into the
    residence from the “septic system, . . . sump pump, [and] sump pump well . . . .”14
    Unfortunately, removing this water from the “foundation . . . coupled with the runoff into the
    gutters and exterior drains from the Main Residence through the subsurface piping into the
    nearby [s]tream was too much for the drainage system to handle.”15 A stone retaining wall
    containing the drainage system partially collapsed.16
    In the storm’s aftermath, the Monzos discovered that the bridges on their property
    were significantly damaged. “The upstream bridge collapsed completely. The downstream
    bridge was more substantial and did not collapse but did suffer some severe damage.”17

    A couple of days after the storm, the Monzos contacted Papa about submitting a claim
    with Nationwide to cover the damage to the retaining wall and bridges.18 Nationwide
    assigned the claim to Melissa Barlow-Carey, a claims associate.19
    Around the same time that they submitted a claim, the Monzos hired
    Fredrick S. Roland, a structural engineer, “to investigate and determine the cause of the
    collapse of a stone pedestrian foot bridge that crosses a small stream on [the Monzos’]
    property.”20 Roland inspected the property and produced a report concluding:
    1. The upstream bridge collapsed as a result of hidden decay
    below the normal water level and the supporting earth
    embankments being scoured away during a thunderstorm. The
    collapse was further exacerbated by a sudden burst of heavy rain
    and debris from trees whose weight was too much to be borne
    by the supporting bridge structure.
    2. The heavy rainfall during a short period of time caused
    significant drainage from roof areas of the main house and into
    the drainage system of underground pipes which open into the
    stream via pipes through the stone wall. The overflow of the
    rain drainage caused a failure of the drainage system in that
    water backed up and resulted in a collapse at the area where
    water was being forced out of the pipes and into the creek. It is
    this aspect of the front stone wall that collapsed.
    3. The heavy rain fall over a short period of time increased the
    water speed creating the scour effect that eroded the stream
    banks.21

    Nationwide hired its own structural engineer, Sihan S. Jawad, to investigate and
    “determine the cause of the damage to the bridge and the stream embankment.”22 Jawad’s
    report concluded:
    [T]he damage to the bridges and the retaining walls . . . was
    caused by soil erosion and soil/hydrostatic pressure. The heavy
    rain in the region on or about the loss date increased the
    soil/hydrostatic pressure and the flow in the stream. Debris
    floating in the stream possibly dammed the flow and may have
    contributed to the damage to the bridges.23
    In October 2017, Papa sent an email to Barlow-Carey to discuss the status of the
    Monzos’ claim.24 Papa wrote, “It sounded like, because of the policy language (or lack
    thereof), that coverage could potentially be afforded. I didn’t and wouldn’t tell them that[,]
    but I figured I’d check in to see what your thoughts are at this point.”25 Barlow-Carey
    responded, “I highly doubt this will be covered.”26
    C.       Nationwide Denies the Claim and the Monzos Sue
    In November 2017, Nationwide sent the Monzos a letter denying their claim.27 In the
    letter, Nationwide asserted that the policy’s earth movement and water damage exclusions
    applied because heavy rain, scouring, and water-borne debris combined to cause the loss.28
    Nationwide asserted that Option R Coverage was unavailable because “[t]he earth

    movement and water damage exclusions . . . apply regardless of whether another covered
    cause of loss . . . contributed to the loss before, after, or at the same time as the excluded earth
    movement or ‘water damage.’”29
    Approximately one year later, the Monzos timely filed a complaint in the Superior
    Court.30 The complaint alleged two counts. Count I sought a declaratory judgment “that
    under the terms of the Nationwide policy, [the Monzos] are entitled to immediate payment
    by Nationwide . . . in connection with the July 23, 2017 storm.”31 Count II alleged that
    Nationwide breached its contractual obligations in bad faith by refusing, “without reasonable
    justification,” “to make complete and timely payment of insurance proceeds to [the Monzos]
    under the Nationwide policy . . . in connection with the July 23, 2017 storm . . . .”32
    Despite describing the homeowners insurance policy “as part of a comprehensive
    insurance coverage plan,”33 the complaint only sought coverage under the homeowners
    policy and did not allege that coverage could be available under another policy.34 For
    example, the complaint defined “the Nationwide Policy” to mean the “homeowners
    insurance contract . . . .”35

    In September 2019, Nationwide filed a motion for summary judgment.36 Nationwide
    argued that it was entitled to summary judgment because, among other things, the policy
    excludes coverage for water damage and earth movement, and there was no dispute that both
    of those excluded perils contributed to the loss.37 Nationwide also argued that the Option R
    Coverage did not apply because there was no “backup” 38 and because the policy contained
    an Anti-Concurrent Causation Clause (the “ACC Clause”) that would defeat coverage if
    excluded and covered perils combined to cause the loss.39
    The Monzos opposed the motion, arguing that summary judgment was premature
    because discovery was incomplete.40 The Monzos also argued that summary judgment was
    inappropriate because there were disputed facts about whether the policy covered their
    claim.41
    In January 2020, the Superior Court held an oral argument regarding summary
    judgment.42 During the argument, the court asked Dana Spring Monzo, “[D]o plaintiffs
    disagree with Mr. Roland’s conclusions as to what caused the damage?”43 Dana answered,
    I would not say that we disagree. We have not finalized the full
    scope of what other areas need to be included.

    Mr. Roland also did not enter the interior of our home to provide
    a full evaluation of the drainage system as it applies to Option R.
    So what was supplied for the loss issue may not be a complete
    report for what it needed for success in litigation.44
    On March 18, 2020, the Superior Court issued a Memorandum Opinion and Order
    granting Nationwide’s motion for summary judgment.45 The court began its analysis by
    holding that there was no dispute that scouring, heavy rain, and water-borne debris
    contributed to the damage:
    At oral argument, Plaintiffs conceded that they are not
    disputing Roland’s findings. Therefore, Plaintiffs agree that the
    damage to the pedestrian bridge was caused, at least in part, by
    “supporting earth embankments being scoured away during a
    thunderstorm” and “debris from trees whose weight was too
    much to be borne by the supporting bridge structure,” and that
    the damage to the wall was caused by “heavy rainfall during a
    short period of time” that drained from the roof area of the house
    into the underground drainage system, ultimately resulting in “a
    collapse [of the wall] at the area where the water was being
    forced out of the pipes and into the creek.”46
    Relying on this purported concession, the court held that Nationwide was entitled to
    summary judgment because “the facts are undisputed that the damage to both the pedestrian
    bridge and the wall w[as] caused by factors . . . not covered under the Policy, namely, ‘earth

    10
    movement’ and ‘water or water-borne material.’”47 The court held that the earth movement
    exclusion applied because “scouring” is a type of earth movement:
    [W]hile it is true that neither “erosion” nor “scour” are explicitly
    named as excluded causes within the Policy, both fall within the
    Policy’s “earth movement” exclusion. “Scour” is a term that
    encompasses “erosion.” Moreover, “erosion” is a term used to
    describe a natural process, whether rapid or gradual, that wears
    away soil. Thus, heavy rainfall and the scouring of the earth
    caused by that rainfall were “natural . . . causes” that resulted in
    “movement,” i.e., erosion, of “earth” surrounding both the
    pedestrian bridge and the wall.48
    The court held that the water damage exclusion applied because there was no dispute
    that water and water-borne material contributed to the damage:
    [T]he Policy excludes damage caused by “water or water-borne
    material,” i.e., by “flood, surface water . . . [or] overflow of a
    body of water” or by “water or water-borne material below the
    surface of the ground.” Although the word “rain” is not
    mentioned in the exclusions, “rain” contributing to a “flood”
    would certainly fall under these exclusions. . . . Additionally, the
    “debris from trees” carried by the stream was “water-borne
    material.” . . . [I]t is undisputed, as noted in Roland’s report, that
    a burst of rainfall swelling a stream, “material” carried along in
    that stream, and water moving “below the surface of the
    ground,” i.e., through the underground drainage system,
    damaged the pedestrian bridge and the wall.49

    Finally, the court held that “even if non-excluded causes contributed to the damage,
    coverage is barred under the ACC Clause, which precludes coverage when excluded and
    non-excluded causes combine to cause damage.”50
    The court rejected the Monzos’ argument that the Option R Coverage was available
    for two reasons.51 First, the court held that the Option R Coverage did not abrogate the ACC
    Clause, meaning that “Plaintiffs are precluded from recovery even if both excluded and non-
    excluded causes combined to damage the wall . . . .”52 Thus, the court reasoned that even if
    a backup covered under the Option R Coverage contributed to the loss, the Monzos were not
    entitled to coverage because other excluded perils, such as scouring, also contributed to the
    loss.
    Second, the court held that Option R Coverage was unavailable because the Monzos
    did not suffer a covered backup:
    Option R . . . applies to damage “caused by . . . water or water-
    borne material” that “[b]acks up through sewers or drains from
    outside the dwelling’s plumbing system” or “[o]verflows from
    a sump pump, sump pump well, or other system designed to
    remove subsurface water or water-borne material from the
    foundation area.” Although Plaintiffs allege that immediately
    following the Storm, they had to remove water that had backed
    up into their residence . . . they are seeking coverage for damage
    to the pedestrian bridge and the wall, not to their residence.
    Moreover, while Roland’s report states that water “backed up
    and resulted in a collapse” and “overflow[ed]’ from the roof area
    of the house into the drainage system, it is clear from reading his
    50
    
    Id.
    51
    Id. at *4-6.
    52
    Id. at *4.
    12
    conclusions in context that, according to Roland, water “backed
    up” from the roof of the house, through the underground
    drainage system, and into the stream, not that it “[b]acked up
    through sewers and drains from outside the dwelling’s plumbing
    system” or “overflow[ed] from a . . . system designed to remove
    subsurface water from the foundation area.”53
    Finally, the court rejected the Monzos’ argument that summary judgment “should be
    denied as premature.”54 The court noted that Superior Court Civil Rule 56(b) allows a party
    to seek summary judgment “at any time” and held that it “ha[d] sufficient facts enabling it to
    render an informed decision.”55 The Court also held that it need not wait for more discovery
    regarding extrinsic evidence because “the Policy’s terms are clear on their face.”56
    D.      The Superior Court Denies the Monzos’ Motion to Alter or Amend the
    Judgment under Superior Court Civil Rule 59(d)
    In March 2020, the Monzos filed a motion seeking to alter or amend the judgment
    under Superior Court Civil Rule 59(d) and seeking reargument under Rule 59(e).57 The
    Monzos argued that their motion was appropriate because: (i) the Superior Court failed to
    respond to the Monzos’ argument that summary judgment was premature; and (ii) the
    Superior Court improperly relied on the Roland report, which was inadmissible both because
    it was hearsay and because it lacked proper authentication.58

    The Superior Court rejected the Monzos’ motion, holding that the court’s summary
    judgment order responded to the Monzos’ argument that summary judgment was
    premature.59 The court noted, “Plaintiffs’ argument on this matter is the same as that raised
    in their brief in opposition to Nationwide’s Motion for Summary Judgment and explained at
    oral argument, and therefore violates the requirements for a motion pursuant to Rule 59.”60
    The court rejected the hearsay and authentication arguments as untimely, noting that
    the Monzos could have raised both evidentiary objections in response to Nationwide’s
    motion for summary judgment.61 The court also cast doubt on the merits of these objections,
    opining that Roland’s report could have qualified for the business records exception to
    hearsay,62 and noting that “Plaintiffs made the Report part of the factual record by their own
    choosing, and thus should have anticipated that the Court would rely on the Report, as part
    of the record, in reaching its decision.”63
    The Monzos appeal the Superior Court’s orders granting Nationwide’s motion for
    summary judgment and denying the Monzos’ post-judgment motion.

    II.    STANDARD OF REVIEW
    “This Court reviews a grant of summary judgment de novo . . . .”64 Summary
    judgment is appropriate if, “viewing the facts in the light most favorable to the nonmoving
    party, the moving party has demonstrated that there are no material issues of fact in dispute
    and that the moving party is entitled to judgment as a matter of law.”65 The Court “review[s]
    questions of law, including contract interpretation, de novo.”66
    The Court reviews for abuse of discretion the Superior Court’s denial of a motion
    under Superior Court Civil Rule 59.67 Under Rule 59, “a motion to alter or amend [a]
    judgment . . . will be granted if the movant shows: ‘(1) an intervening change in controlling
    law; (2) the availability of new evidence; or (3) the need to correct clear error of law or to
    prevent manifest injustice.’”68 “[T]he Court will deny the motion if it merely restates
    arguments already considered and rejected during the litigation.”69

    III.     ANALYSIS
    This appeal asks the Court to decide two issues. First, whether the Superior Court
    erred by granting Nationwide’s motion for summary judgment. Second, whether the
    Superior Court abused its discretion by denying the Monzos’ post-judgment motion. The
    Court addresses each issue in turn.
    A.     The Superior Court Properly Granted Summary Judgment Regarding
    the Pedestrian Bridge, But Erred by Granting Summary Judgment
    Regarding the Retaining Wall
    For the purposes of summary judgment and this appeal, Nationwide admits that the
    Monzos have met the threshold requirements for coverage under the homeowners insurance
    policy.70 The sole question before the Court is whether, drawing all reasonable factual
    inferences in the Monzos’ favor, the policy contains exclusions that unambiguously apply to
    the Monzos’ claim.
    The Court answers this question in three parts. The first part introduces the relevant
    provisions of the homeowners insurance policy. The second part analyzes whether
    Nationwide was entitled to summary judgment regarding the collapsed pedestrian bridge.
    The third part analyzes whether Nationwide was entitled to summary judgment regarding
    the collapsed retaining wall.

    1.      The homeowners insurance policy contains four provisions
    relevant to this appeal
    Insurance policies are contracts, and Delaware courts apply the ordinary principles of
    contract interpretation to construe insurance policies.71 Thus, “where the language of a
    policy is clear and unequivocal, the parties are to be bound by its plain meaning.”72
    “[W]here an ambiguity does exist,” however, “the doctrine of contra proferentem
    requires that the language of an insurance policy be construed most strongly against the
    insurance company that drafted it. It is ‘the obligation of the insurer to state the terms of the
    policy.’”73   Stated differently, if there is more than one reasonable interpretation of an
    insurance policy, Delaware courts apply the interpretation that favors coverage.
    “An insurance policy is not ambiguous merely because the parties do not agree on its
    construction.”74 Rather, an insurance policy “is ambiguous only when the provisions in
    controversy are reasonably or fairly susceptible of different interpretations or may have two
    or more different meanings.”75 “Delaware should not ‘destroy or twist policy language

    The homeowners insurance policy contains four provisions relevant to this appeal.
    First, the policy contains the following earth movement exclusion:
    We do not cover loss to any property resulting directly or
    indirectly from any of the following. Such a loss is excluded
    even if another peril or event contributed concurrently or in any
    sequence to cause the loss.
    a) Earth Movement and Volcanic Eruption. Earth movement
    means: earth movement due to natural or unnatural causes,
    including mine subsidence; earthquake; landslide; mudslide;
    earth shifting, rising or sinking. Volcanic eruption means:
    eruption; or discharge from a volcano.77
    Second, the policy contains the following water damage exclusion:
    We do not cover loss to any property resulting directly or
    indirectly from any of the following. Such a loss is excluded
    even if another peril or event contributed concurrently or in any
    sequence to cause the loss.
    ....
    b) Water or damage caused by water-borne material. Loss
    resulting from water or water-borne material damage described
    below is not covered even if other perils contributed, directly or
    indirectly to cause the loss. Water and water-borne material
    damage means:

    (1) flood, surface water, waves, tidal waves, overflow of
    a body of water, spray from these, whether or not driven
    by wind.
    (2) water or water-borne material which:
    (a) backs up through sewers or drains from
    outside the dwelling’s plumbing system; or
    (b) overflows a sump pump, sump pump well or
    other system designed to remove subsurface
    water or water-borne material from the
    foundation area.
    (3) water or water-borne material below the surface of
    the ground, including water or water-borne material
    which exerts pressure on, seeps or leaks through a
    building, sidewalk, driveway, foundation, swimming
    pool, or other structure.78
    Third, embedded within the prior two exclusions is the ACC Clause stating, “We do
    not cover loss to any property resulting directly or indirectly from any of the following. Such
    a loss is excluded even if another peril or event contributed concurrently or in any sequence
    to cause the loss.”79
    Fourth, the policy contains the following Option R Coverage:
    We will pay up to the limit of liability . . . for direct damage to
    covered property caused by or resulting from water or water-
    borne material which:
    1. backs up through sewers or drains from outside the
    dwelling’s plumbing system; or

    This is the most we will pay for all covered property under
    Coverage A — Dwelling, Coverage B — Other Structures and
    Coverage C — Personal Property.
    EXCLUSIONS
    We do not cover:
    1. loss caused by the negligence of an insured; or
    2. if the loss occurs or is in progress within the first five
    days of the Inception of this coverage unless added at
    renewal.
    All other damage resulting from water or water-borne material
    not mentioned above is excluded as stated in Section I - Property
    Exclusion 1.b).

    We will pay for that part of the covered loss that is above the

    2.      The Superior Court properly granted summary judgment
    regarding the collapsed pedestrian bridge
    The Superior Court held that Nationwide was entitled to summary judgment
    regarding the collapsed bridge because there was no dispute that two excluded perils
    contributed to the damage: (i) “earth movement” caused by the scouring of supporting earth
    embankments, and (ii) “water damage” caused by the weight of water and water-borne
    material on the bridge.81 Noting that the policy contains an ACC Clause, the court
    determined that the Monzos could not prevail regardless of whether other covered perils
    contributed to the damage.82
    The Monzos argue that the Superior Court erred because neither exclusion
    unambiguously applies to the collapsed bridge.83 According to the Monzos, the earth
    movement exclusion does not apply to “scouring” because the exclusion does not mention
    “scouring,” “erosion,” or that earth movement can be combined with water.84 In support,
    the Monzos note that other insurers have drafted earth movement exclusions that specifically
    refer to “erosion” and state that earth movement is excluded, “combined with water or not.”85

    21
    Thus, the Monzos contend that the exclusion only applies to the types of earth movement
    the exclusion specifically lists, such as earthquakes and volcanic eruptions.86
    The Monzos argue that the water damage exclusion does not apply to the collapsed
    bridge for two reasons.87 First, the Monzos argue that the water damage exclusion only
    applies to damage related to getting insured property wet, not damage caused by the weight
    of water on insured property.88 Second, the Monzos argue that applying the exclusion to
    water from the stream would make their insurance coverage illusory because Nationwide
    knew when it issued the policy that there was a stream on the Monzos’ property.89
    Nationwide answers that the policy’s definition of excluded earth movement
    “includes a situation like the instant one, where water saturates the earth, causing it to shift
    or sink.”90 Thus, according to Nationwide, “[t]he actions described by both engineers which
    contributed to the collapse of the bridge would involve ‘earth shifting, rising or sinking,’
    which is specifically listed as an exclusion in the policy.”91
    Similarly, Nationwide asserts that the water damage exclusion applies because “[t]he
    Policy clearly and unambiguously excludes coverage for ‘water damage’ caused by
    ‘flood.’”92 Thus, because “the ‘severe storm’ resulted in a rain-induced flood, which diverted

    tree debris into the stream, the policy’s exclusion for ‘water or damage caused by water-
    borne material’ bars recovery.”93
    a)     The earth movement exclusion unambiguously applies to
    the collapsed bridge
    The Court’s analysis focuses on the earth movement exclusion, which is dispositive.
    The Monzos conceded below that they did not “disagree” with Roland’s conclusion that
    “[t]he upstream bridge collapsed as a result of hidden decay below the normal water level
    and the supporting earth embankments being scoured away during a thunderstorm.”94 The
    affidavit Eric Monzo submitted in opposition to summary judgment did not contradict
    Roland’s conclusions regarding what caused the bridge’s collapse.95 It is therefore
    undisputed that the pedestrian bridge collapsed, at least in part, because rainwater “scoured
    away” portions of the earth embankments supporting the bridge.
    The verb “scour” has been defined as meaning “to remove dirt and debris from
    something, such as a pipe or ditch” or “to clear, dig, or remove by or as if by a powerful
    current of water.” 96 Thus, Roland’s unrebutted opinion was that water from the storm carried
    away earth supporting the bridge, contributing to the bridge’s collapse.

    The policy’s earth movement exclusion provides that Nationwide will “not cover loss
    to any property resulting directly or indirectly from . . . earth movement due to natural or
    unnatural causes, including mine subsidence; earthquake; landslide; mudslide; earth shifting,
    rising or sinking.”97 Although the exclusion does not list “erosion” or “scouring,” the plain
    meaning of “earth movement” encompasses “scouring” of earth embankments.
    “Movement” refers to the verb “move,”98 which means “to change the place or position of,”
    “to transfer (something, such as a piece in chess) from one position to another,” or “to cause
    to advance.”99     The “scouring” of earth embankments necessarily involves “earth
    movement” because it refers to a “change in place or position” of earth supporting the bridge.
    Similarly, “shifting” refers to the verb “shift,” which means “to change place or
    position.”100 The “scouring” of supporting earth embankments necessarily involves “earth
    shifting” because it refers to a “change [in] place or position” of the earth from the supporting
    embankment to the earth’s final destination downstream. Therefore, the plain meaning of
    “earth shifting” encompasses the “scouring” of supporting earth embankments.
    The Monzos do not offer an alternative interpretation of the earth movement
    exclusion explaining why “scouring” is not “earth movement.” Instead, the Monzos rely on

    a more general objection that the earth movement exclusion is only unambiguous as applied
    to the types of earth movement the exclusion specifically lists, such as earthquakes and
    volcanic eruptions.101 This argument fails to address the exclusion’s use of the word
    “including,”102 a term of expansion indicating that the policy does not provide a
    comprehensive list of excluded earth movements. Further, the plain meanings of the
    enumerated terms “earth movement” and “earth shifting” encompass the scouring of
    supporting earth embankments for the reasons provided above.
    The Monzos’ argument that the exclusion does not clearly apply to earth movement
    when combined with water is equally unavailing. The earth movement exclusion provides
    that Nationwide will not cover losses “resulting directly or indirectly from . . . earth
    movement due to natural or unnatural causes . . . .”103 The plain meaning of this exclusion
    does not carve out an exception for water-related earth movement. Rather, the exclusion
    disclaims coverage whenever some natural or unnatural cause—like rainwater—causes
    “earth movement” as defined under the policy.
    The types of earth movement the exclusion enumerates further undercuts the
    Monzos’ argument. The exclusion lists “mudslide[s]” as an example of excluded earth

    movement.104 Mudslides are associated with heavy rain,105 as was the case with the scouring
    Roland described.106
    Finally, the Monzos include one paragraph suggesting—without citation to the
    record—that “[t]he stone and rock that washed away during the storm was not loose stone
    or rock, but rather, was a physical part of the” bridge.107 If properly supported, this argument
    might have raised some doubt regarding whether the material that the scouring moved was
    “earth” to which the earth movement exclusion applies. The record before the Court,
    however, does not support the Monzos’ assertion. Roland’s report concluded that “the
    supporting earth embankments” were scoured away,108 not the stone and rock composing
    the bridge. And the Monzos have not provided the Court with citations to support their
    bridge-not-earth theory.
    For the reasons provided above, the Court affirms the Superior Court’s holding that
    the earth movement exclusion applies to the collapsed bridge. The plain meaning of “earth
    movement” encompasses the scouring of earth embankments, and there is no dispute that
    the scouring of supporting earth embankments contributed to the bridge’s collapse.

    Accordingly, the Superior Court did not err by holding that the earth movement exclusion
    unambiguously applies to the collapsed pedestrian bridge.109
    b)      The ACC Clause prevents the Monzos from receiving
    compensation for the collapsed pedestrian bridge
    The Superior Court held that the water damage exclusion unambiguously applies to
    the collapsed bridge because Roland concluded that the weight of water and water-borne
    material contributed to the damage.110 The parties advance various arguments regarding the
    water damage exclusion, with the Monzos arguing that the exclusion does not apply111 and
    Nationwide arguing the opposite.112
    The Court need not address the water damage exclusion to hold that Nationwide was
    entitled to summary judgment. The policy contains an ACC Clause, which provides that if
    an excluded peril contributes to a loss, “[s]uch a loss is excluded even if another peril or event
    contributed concurrently or in any sequence to cause the loss.”113 Thus, because the
    undisputed facts show that excluded earth movement contributed to the bridge’s collapse,
    Nationwide is entitled to summary judgment regardless of whether the water damage
    exclusion applies to the collapsed bridge.
    109
    The Superior Court’s holding can be read to suggest that erosion, like scouring, is a type of
    excluded earth movement. See Monzo, 
    2020 WL 1317276
    , at *4. This Court’s opinion does not
    address whether the earth movement exclusion unambiguously applies to “erosion.” Instead, the
    Court holds more narrowly that “scouring” of supporting earth embankments by fast-moving water
    is a type of excluded earth movement.

    The Monzos do not propose an alternative interpretation of the ACC Clause that
    would allow coverage even though an excluded peril contributed to a loss. Instead, the
    Monzos argue that the ACC Clause does not apply to “other structures,” like the pedestrian
    bridge, because such structures are “not real or personal property.”114
    This argument fails for three reasons. First, the Monzos waived this argument by
    waiting until their reply brief to assert that the ACC Clause does not apply to the collapsed
    bridge. “Under Supreme Court Rule 14, an appellant waives an argument if he does not
    argue its merits within the body of his opening brief.”115 The Monzos’ opening brief does
    not argue that the ACC Clause does not apply to the bridge. Instead, the opening brief asserts
    that the ACC Clause does not apply to the retaining wall.116 Thus, the Monzos failed to
    timely argue that the ACC Clause does not apply to the collapsed bridge.
    Second, this argument would defeat the Monzos’ claims for relief. The Monzos seek
    compensation for the collapsed bridge under Coverage B of the homeowners insurance
    policy. Coverage B “cover[s] accidental direct physical loss to property . . . .”117 Thus, if the

    28
    Monzos’ argument is correct, their claim fails because the bridge is not “property” to which
    the insurance coverage applies.
    Third, the Monzos rely on a cramped definition of “property.” The plain meaning of
    “property” is not limited to real or personal property.118 The pedestrian bridge plainly falls
    within the plain meaning of “property.”
    Accordingly, the Court affirms the Superior Court’s holding that Nationwide was
    entitled to summary judgment regarding the collapsed pedestrian bridge. The undisputed
    facts establish that excluded earth movement contributed to the collapse, and the ACC
    Clause unambiguously applies to the pedestrian bridge.
    c)      The Superior Court did not err by granting summary
    judgment while discovery was ongoing
    Because the Court affirms the Superior Court’s grant of summary judgment regarding
    the pedestrian bridge, the Court must briefly address two other issues the Monzos raise. First,
    the Monzos argue that the Superior Court erred by granting summary judgment before
    discovery was complete.119 This argument fails because the Monzos have not identified
    other discovery that could change the Court’s conclusion that Nationwide is entitled to
    summary judgment regarding the collapsed bridge.
    118
    See, e.g., Property, Black’s Law Dictionary (10th Ed. 2014) (defining “property” as “any external
    thing over which the rights of possession, use, and enjoyment are exercised.”).
    119
    Opening Br. 26-34.
    29
    For example, the Monzos complain that “Nationwide in its responses to the
    interrogatories sought to improper[ly] [limit] the scope of the litigation to the Homeowners’
    Policy and not answer questions completely relating to other policies.”120 The Monzos
    reason that this limitation was improper because the homeowners policy was part of a
    broader package of “comprehensive insurance coverage,” which included other types of
    insurance coverage, such as “an excess liability policy, a marine policy, automobile policy,
    and general liability coverage . . . .”121
    Discovery related to other insurance policies would not change the outcome of the
    motion, however, because the Monzos’ complaint only seeks coverage under the
    homeowners’ insurance policy.122 Regardless of whether Nationwide issued other policies
    that might cover the damage, the Monzos made a tactical decision to only seek coverage
    under the homeowners insurance policy. Thus, discovery regarding other insurance policies
    would not have helped the Superior Court answer the question the Monzos’ complaint posed:
    whether the homeowners insurance policy covered the collapsed bridge.
    Similarly, the Monzos argue that they needed more discovery regarding Papa’s view
    that the homeowners insurance policy, or another policy that was part of the comprehensive

    insurance scheme, covered the collapsed bridge.123 Further, the Monzos argue that they
    needed more discovery into their discussions and negotiations with Papa regarding flood
    insurance and the flood insurance “waiver.”124
    This discovery would not change the analysis. The Monzos do not allege that Papa
    is a legal expert, and the Superior Court did not need expert testimony to answer the purely
    legal question of whether the policy covered the claim. Further, Papa’s views on the potential
    for coverage under other insurance policies would not have helped the court determine
    whether the homeowners insurance policy covered the collapsed bridge. Thus, the court did
    not need to wait to entertain more discovery regarding Papa’s views on coverage.
    The Monzos’ argument regarding the flood insurance “waiver” fails for similar
    reasons. Even if the Court accepts Eric Monzo’s allegation that he did not intend to waive
    flood insurance covering the pedestrian bridge,125 the earth movement exclusion would still
    defeat the Monzos claims.          The Option R provision—which the Monzos seem to
    characterize as flood insurance126—does not alter the earth movement exclusion and does
    not abrogate the ACC Clause.127             Thus, the Monzos cannot prevail even if the

    See, e.g., Reply Br. 21 (“[T]here was no waiver of flood insurance as to the collapsed structures

    31
    Option R Coverage would apply to the water damage that the pedestrian bridge suffered.
    The undisputed facts establish that excluded earth movement contributed to the loss.
    Finally, the Monzos assert that summary judgment was premature because
    Cornerstone, the company that Nationwide hired to conduct the original risk assessment,128
    had not responded to a subpoena regarding Cornerstone’s inspection of the Monzos’
    residence.129 As with the prior items, discovery regarding a risk assessment authored
    approximately six years before the storm would not have helped the Superior Court
    determine whether the undisputed facts established that an excluded peril, like earth
    movement, contributed to the bridge’s collapse.
    For the reasons provided above, the Court holds that the Superior Court’s grant of
    summary judgment was not premature. Although discovery was incomplete, the additional
    discovery items the Monzos seek would not have changed the Superior Court’s conclusion
    that Nationwide was entitled to summary judgment because excluded earth movement
    contributed to the bridge’s collapse.

    d)      The Superior Court did not err by considering Roland’s
    report
    The Monzos also argue that the Superior Court should not have relied on Roland’s
    report because it was incomplete and because the Monzos had not yet decided whether they
    intended to call Roland as an expert at trial.130 The Monzos’ arguments are unpersuasive.
    Even if Roland’s report was “incomplete,” during the oral argument the Monzos told the
    court that they “would not say that we disagree” “with Mr. Roland’s conclusions as to what
    caused the damage.”131 This concession applied to Roland’s conclusion that scouring
    contributed to the bridge’s collapse,132 and the Monzos do not explain why allowing Roland
    more time to draft a more comprehensive report would change his conclusion that scouring
    contributed to the collapse.
    Similarly, whether the Monzos intended to call Roland as an expert witness has no
    bearing on whether the report was admissible for the purposes of assessing Nationwide’s
    motion for summary judgment. It is also incongruous to hear the Monzos complain about
    the Superior Court’s reliance on Roland’s report. The Monzos hired Roland to investigate
    why the bridge collapsed,133 and the affidavit Eric Monzo submitted in opposition to

    that crosses a small stream on your property.” (emphasis added)).
    33
    summary judgment relied upon Roland’s conclusions to support the Monzos arguments
    regarding why the retaining wall collapsed.134
    Accordingly, the court did not err by relying on Roland’s report. The Monzos have
    not provided the court with any reasonable basis to infer that additional discovery would
    change Roland’s conclusions, failed to timely assert any credible argument challenging
    admissibility, and relied on Roland’s report to build their own arguments opposing summary
    judgment with respect to the retaining wall.
    3.      The Superior Court erred by granting summary judgment
    regarding the collapsed retaining wall
    The Superior Court held that Nationwide was entitled to summary judgment
    regarding the collapsed retaining wall because there was no dispute that scouring, rainwater,
    and water-borne debris contributed to the damage.135 Additionally, the court held that
    Option R Coverage was unavailable because: (i) the Monzos did not seek coverage for
    damage to the residence; and (ii) the undisputed facts showed that “water ‘backed up’ . . .
    from the roof area of the house into the drainage system, . . . not that it ‘[b]acked up through
    sewers and drains from outside the dwelling’s plumbing system’ or ‘overflow[ed] from a
    . . . system designed to remove subsurface water . . . .”136
    134
    See A229 (“Unfortunately, the removal of this subsurface water . . ., according to Mr. Roland,
    . . . was too much for the drainage system to handle. A portion of the stone drainage wall system
    . . . collapsed . . . .” (emphasis added)).

    34
    The Monzos argue that the Superior Court erred by granting Nationwide’s motion for
    summary judgment. In addition to the arguments discussed above, the Monzos assert that
    the earth movement exclusion does not apply to the retaining wall because, unlike the
    pedestrian bridge, Roland “d[id] not suggest that the collapse of the drainage system [and
    retaining wall] had anything to do with the erosion or scouring of the streambanks.”137
    The Monzos argue that the water damage exclusion does not defeat their claim
    because the Option R Coverage applies to the water backup that damaged the retaining
    wall.138 Thus, although water and water-borne debris contributed to the collapse, the
    Monzos assert that such water damage is expressly covered under the policy.
    Nationwide answers that the earth movement exclusion applies because the
    undisputed facts establish that scouring, a type of excluded earth movement, damaged the
    retaining wall.139 Similarly, Nationwide argues that Option R Coverage is unavailable
    because such coverage only protects the dwelling140 and because “the cause-in-fact of the
    water that . . . ‘backed up’ the ‘drainage system of underground pipes’ was from the storm, a
    natural phenomenon.”141
    Finally, Nationwide argues that even if the Option R Coverage is available, the
    Monzos’ claim still fails because the Roland and Jawad reports both “concluded that debris
    137

    35
    from trees was carried by the flood waters in the stream, contributing to the damage to . . . the
    retaining wall.”142 Thus, Nationwide reasons that the Monzos’ claim cannot succeed
    because there is no dispute that water-borne material, a type of excluded water damage to
    which Option R Coverage does not apply, contributed to the retaining wall’s collapse.
    The Court holds that Nationwide was not entitled to summary judgment regarding
    the collapsed retaining wall.      Unlike the pedestrian bridge, the undisputed facts do not
    establish that “scouring” contributed to the retaining wall’s collapse. Roland’s report
    concluded the wall collapsed because heavy rainfall caused the drainage system to back up:
    The heavy rainfall during a short period of time caused
    significant drainage from roof areas of the main house and into
    the drainage system of underground pipes which open into the
    stream via pipes through the stone wall. The overflow of the
    rain drainage caused a failure of the drainage system in that
    water backed up and resulted in a collapse at the area where
    water was being forced out of the pipes and into the creek. It is
    this aspect of the front stone wall that collapsed.143
    Similarly, Eric Monzo’s affidavit alleged that the retaining wall collapsed because
    “the removal of . . . subsurface water from the Main Residence’s foundation . . . coupled with
    the run[off] into the gutters and exterior drains . . . was too much for the drainage system to
    handle.”144 Neither piece of evidence unambiguously links scouring to the retaining wall.

    143
    A148.
    144
    A229.
    36
    Further, Roland’s report and Eric Monzo’s affidavit describe a water backup to which
    Option R Coverage would apply. The Option R provision states that Nationwide will cover
    damage to “covered property caused by or resulting from water or water-borne material
    which: 1. backs up through sewers or drains from outside the dwelling’s plumbing system;
    or 2. overflows from a sump pump . . . or other system designed to remove subsurface water
    or water-borne material from the foundation area.”145
    Roland concluded that the water that caused the backup came from the exterior drains
    that carry water from the residence’s roof to the stream.146 Similarly, Eric Monzo alleged
    that water from the residence’s sump pump system, combined with water from “the gutters
    and exterior drains,” overwhelmed the drainage system, causing a water backup that led to
    the retaining wall’s collapse.147
    The Option R provision applies to this type of water backup. The gutters and exterior
    drains that carry rainwater from the roof to the stream are “drains” located “outside the
    dwelling’s plumbing system.” And Roland and Eric Monzo both concluded that water from
    those systems overwhelmed the pipes that carried water to the stream, causing a water
    backup that led to the retaining wall’s collapse. Thus, the record supports a reasonable
    inference that a backup, covered under Option R, caused the retaining wall to collapse.

    Id. (emphasis added).
    146
    A148.
    147
    A229.
    37
    Similarly, Nationwide does not dispute that the residence’s sump pump system is a
    “sump pump” as defined under the policy.148 Eric Monzo alleged in his affidavit that the
    sump pump overflowed, contributing to the glut of water that overwhelmed the drainage
    system.149 Thus, the record supports a reasonable inference that an overflow from a sump
    pump system, covered under the second paragraph of Option R, contributed to the water
    backup that caused the loss.
    Nationwide raises three unpersuasive arguments explaining why the Option R
    Coverage does not apply to the retaining wall.             First, Nationwide argues that the
    Option R Coverage only protects the residence, and therefore does not cover damage to
    “other structures,” like the retaining wall.150 This argument contradicts the policy’s plain
    meaning. Although the policy does not define the term “covered property,” the Option R
    Coverage provision states, “This is the most we will pay for all covered property under”
    Coverages A, B, and C.151 A reasonable policyholder would therefore expect that “covered
    property” refers to all of the property that the policy covers, including “other structures,” like
    148
    See Answering Br. 8 (“Appellants did have a small amount of water enter the basement due to
    the back up of water from the sump pump. Appellants were able to remedy the problem without any
    property damage. Any potential claim related to water in the basement is not part of this case.”).

    38
    the retaining wall, to which Coverage B applies. Nationwide does not dispute that the
    retaining wall is an “other structure” covered under the policy.152
    Nationwide’s argument also conflates a peril that can trigger Option R Coverage—
    water that backs up “through sewers or drains from outside the dwelling’s plumbing
    system”—with the property that the Option R Coverage insures.153 It may be true that a
    policyholder seeking coverage for a backup must show that the water came from a source
    “outside the dwelling’s plumbing system.” Nonetheless, if such a covered backup occurs,
    Option R Coverage applies to “covered property” regardless of whether that property was
    part of the residence or located inside the residence.
    Finally, Nationwide fails to explain why the policy uses the broad term “covered
    property” if Option R Coverage is limited to the “residence.”154 Nationwide’s own argument
    relies on the policy’s use of the term “residence” when describing covered backups to infer
    that Option R Coverage only protects the residence.155 This language demonstrates that
    Nationwide was aware of the difference between the words “residence” and “covered
    property,” and the Court will not assume that Nationwide’s decision to use the broader term
    “covered property” was accidental.
    152
    See, e.g., Answering Br. 13 (“The Policy covers ‘accidental direct physical loss’ to ‘Other
    Structures,’ such as the pedestrian bridge and the retaining wall . . . .” (emphasis added)).
    153
    See id.
    154
    See A304.
    155
    Answering Br. 24.
    39
    Accordingly, the Court rejects Nationwide’s argument that the Option R Coverage
    does not apply to the retaining wall because the retaining wall is not part of the residence.
    Nationwide did not include such a limitation in the policy, and a reasonable policyholder
    would not expect that Option R Coverage is so limited.
    Second, Nationwide suggests that Option R Coverage only applies to water from
    artificial sources, such as sewer backups, and therefore does not apply to backups caused by
    natural phenomena, like rain.156 Nothing in the policy limits Option R Coverage to backups
    from artificial sources. The trigger for Option R Coverage is damage to covered property
    caused by “[w]ater or water-borne material . . . [that] backs up through sewers or drains . . .
    [or] overflows from a sump pump . . . or other system designed to remove subsurface water
    or water-borne material from the foundation area.”157 This language does not create the
    distinction between natural and artificial sources of water that Nationwide suggests. Adding
    a limitation on coverage that Nationwide failed to include in its policy would be contrary to
    Delaware law construing ambiguous contract provisions in favor of policyholders.158
    Accordingly, the Court rejects Nationwide’s argument that Option R Coverage only applies
    to backups caused by artificial events.
    Third, Nationwide argues that even if Option R Coverage is available, the Monzos’
    claim still fails because other types of excluded water damage contributed to the retaining

    40
    wall’s collapse.159 As noted above, the undisputed facts support a reasonable inference that
    the sole cause of the retaining wall’s collapse was a water backup from the residence’s
    drainage system. Thus, there remain disputed facts regarding whether other types of
    excluded water damage contributed to the loss.
    Further, the water damage exclusion would not unambiguously apply to tree debris
    carried by the force of water into the stream. Although such tree debris might meet the
    ordinary definition of “water-borne material,” the policy defines “water-borne material
    damage” to mean either: (i) a backup of water-borne material, as defined under Option R,
    or (ii) “water or water-borne material below the surface of the ground . . . .”160 This language
    does not unambiguously apply to the tree debris that could have damaged the retaining wall.
    Tree debris carried in the stream is not “below the surface of the ground” because the stream
    is not below the ground. Similarly, tree debris carried into the drainage system would not be
    excluded because the Option R Coverage expressly covers that peril.
    Thus, the only variety of excluded water damage that might have contributed to the
    loss is “flood, surface water, waves, tidal waves, overflow of a body of water, spray from
    these, whether or not driven by wind.” Nonetheless, for the reasons provided above, the
    undisputed facts do not establish that such water contributed to the retaining wall’s collapse.

    See A280; A304.
    41
    Accordingly, the Court reverses the Superior Court’s order granting Nationwide
    summary judgment regarding the collapsed retaining wall. There are material disputed facts
    regarding whether the sole cause of the damage was a water backup to which the policy’s
    Option R Coverage applies.
    B.     The Superior Court Did Not Abuse Its Discretion by Denying the
    Monzos’ Motion under Superior Court Civil Rule 59
    The Monzos argue that the Superior Court abused its discretion by denying their post-
    judgment motion under Rule 59.161 According to the Monzos, the Superior Court should
    have granted the motion for three reasons. First, summary judgment was premature because
    discovery was ongoing.162 Second, the Superior Court should not have relied on the Roland
    report, which was incomplete, lacked authentication, and was inadmissible hearsay.163
    Third, the record and the policy did not support summary judgment.164
    The Court rejects each argument. For the reasons discussed above, summary
    judgment was not premature; the Superior Court did not err in relying on the Roland report;
    and, the record and policy supported summary judgment, as explained above. Accordingly,
    the Court holds that the Superior Court did not abuse its discretion by denying the Monzos’
    Rule 59 motion. The Monzos could not use Rule 59 to rehash arguments that they made, or
    could have made, before the court granted summary judgment.
