    Carol Crispino v. Township of Sparta (A-16-19) (083171)
    Argued March 16, 2020 -- Decided July 22, 2020
    ALBIN, J., writing for the Court.
    In this appeal, the Court considers a resolution, passed by defendant Township of
    Sparta (Township), that imposed a special assessment on fifty-eight properties to recoup
    public funds expended in the rehabilitation of a private dam owned by the Glen Lake
    Beach Club, Inc. (Beach Club).
    The Beach Club owns Glen Lake and the Glen Lake Dam, which impounds the
    water that forms the lake. All owners of real estate within a specifically delineated
    perimeter near the lake known as the “reserve” -- as set forth in the Beach Club’s bylaws
    -- are automatically eligible for membership and voting rights.
    To fund necessary repairs to the dam, the Beach Club received a loan from the
    New Jersey Department of Environmental Protection’s Dam, Lake and Stream Project
    Fund. In accordance with N.J.S.A. 58:4-12(d)(1), the Township agreed to serve as a co-
    borrower: the Beach Club would be responsible for repayment of the loan and the
    Township would act as the “collection agent” by passing an ordinance imposing a special
    assessment on “real estate in the Township benefitted by [the dam] improvement.”
    The Township Council enacted Ordinance 16-03, which authorized the Township
    to impose a special assessment on “the benefitted properties” of the dam project, and
    Ordinance 16-04, which established an Assessment Commission to identify the benefitted
    properties and to determine the assessment to be imposed on those properties.
    In March 2016, the Council appointed Scott Holzhauer, a real estate appraiser and
    consultant, to assist the Assessment Commission in fulfilling its charge. Holzhauer
    recommended that fifty-eight properties that fell within the Beach Club’s “reserve” be
    subject to the special assessment to repay the loan. The owners of those properties
    received a “peculiar benefit” or “advantage,” according to Holzhauer, because they have
    the option to become members of the Beach Club and to enjoy its recreational amenities.
    Holzhauer devised an approach to allocate the special assessment by dividing the
    properties in the “reserve” into three separate categories: (1) seven lakefront properties,
    (2) eleven lakeview properties with lake access, and (3) the forty remaining properties.
    1
    In that three-tiered approach, Holzhauer assigned “share values” to each category,
    allocating the highest share value to lakefront properties (2.0), a lower value to
    lakeview/access properties (1.5), and the lowest value to all other properties (1.0).
    Holzhauer’s report does not explain the methodology he followed in assigning the values
    to the three classes of property.
    Despite opposition from some residents, the Township Council passed Resolution
    6-1, adopting the recommendations made in Holzhauer’s report. Plaintiffs filed an action
    in lieu of prerogative writs in Superior Court challenging the validity of Resolution 6-1.
    The court voided Resolution 6-1, reasoning that the Township arbitrarily applied the
    special assessment to plaintiffs’ properties. The Appellate Division reversed, and the
    Court granted certification. 
    239 N.J. 600
    (2019).
    HELD: The expert report relied on by the Township did not apply any reliable
    methodology to assure that the assessment allocating the costs among the properties was
    “in proportion to and not in excess of the benefits conferred,” as required by N.J.S.A.
    58:4-12(d)(1) and other statutes. The Court is constrained to invalidate Sparta Township
    Resolution 6-1, which imposes a special assessment on plaintiffs’ properties to recoup the
    costs of the dam restoration project. The Township must pass a resolution allocating
    costs based on a valid methodology in accordance with the applicable statutes and
    relevant case law.
    1. The Dam, Lake and Stream Project Fund provides a means for the owner of a private
    dam, such as a lake club or association, to secure a loan for the rehabilitation project.
    N.J.S.A. 58:4-12(d)(1) provides two important features: (1) the cost of an improvement
    funded under this section must be assessed “in the same manner as provided for the
    assessment of local improvements generally under chapter 56 of Title 40 of the Revised
    Statutes,” and (2) the assessment against the properties benefitted must be “in proportion
    to and not in excess of the benefits conferred.” The plain language of the statute makes
    clear that the Legislature intended to incorporate the law governing the special
    assessments for local improvements under Title 40 into Title 58’s assessment for private
    dam and lake improvements financed by public funds. By that act of incorporation, the
    Legislature did not have to repeat the procedural and substantive standards for the
    imposition of an assessment already set forth comprehensively in Title 40. The
    Township understood that the special assessment process was governed by both Title 58
    and Title 40. (pp. 17-20)
    2. The justification for any special assessment levied for the purpose of financing a local
    improvement, N.J.S.A. 40:56-27, or an improvement to a privately owned dam, N.J.S.A.
    58:4-12, is that the assessed property has received a benefit from the improvement. If
    there is no “peculiar benefit, advantage or increase in value” to the property from the
    improvement, then there is no basis for imposing an assessment. See N.J.S.A. 40:56-27.
    Under relevant case law, the benefit to the assessed property must be certain rather than
    2
    speculative, although it may arise in the future, and the benefit to the specific property
    must be substantially greater than to the public in general. An assessment, moreover,
    must be proportionate to the benefit conferred on the property. The proportionality
    requirement is measured by a standard of reasonableness, not by scientific precision. See
    N.J.S.A. 58:4-12(d)(1) (“in proportion to . . . the benefits conferred”); N.J.S.A. 40:56-27
    (“as nearly as may be in proportion to”). (pp. 21-23)
    3. The test often used to determine the value of the benefit and the amount of the
    assessment is the difference between the market value of the land before and after the
    improvement. Nevertheless, no inflexible formula applies, nor is mathematical precision
    required. Another assessment methodology may be used, so long as the result is a just
    and equitable assessment of the benefits conferred. The value of the benefit conferred on
    the assessed property by the improvement must be established by reliable proof. To state
    the obvious, a municipality cannot impose an assessment based on an arbitrary
    methodology. (pp. 23-24)
    4. The Holzhauer report, which was adopted by the Assessment Commission and the
    Township Council, did not comport with the statutory mandates and the governing case
    law. Holzhauer simply concluded that property owners listed within the geographical
    ambit of the Beach Club’s bylaws received a “benefit” because of “their right, by
    property ownership and/or interest, to become a member of the club and therefore have
    access to the lake and other amenities.” Plaintiffs suggest that the Beach Club randomly
    placed their properties in the “reserve,” pointing to properties an equal distance from the
    lake, whose owners are not automatically eligible for membership in the Beach Club.
    Additionally, there is lack of certainty whether all property owners within the Beach Club
    “reserve” are, in fact, automatically eligible for membership. Even assuming that
    plaintiffs were eligible to become members of the Beach Club and that such membership
    conferred on them a benefit from the dam restoration project, the Holzhauer report does
    not set forth a rational methodology for the assessments imposed on plaintiffs’ properties.
    Holzhauer did not explain how he arrived at assigning value shares to each category or
    refer to any reliable methodology to support his opinion. (pp. 25-28)
    5. Special assessments cannot be imposed on properties based on arbitrary
    categorizations or speculative valuations. The Court concludes that the presumption of
    validity accorded to Resolution 6-1 has been overcome by clear and convincing evidence
    and invalidates Resolution 6-1 as an arbitrary and unreasonable law. (pp. 28-29)

    Calvert Nathans, on the briefs).
    Thomas N. Ryan argued the cause for respondent
    (Laddey, Clark & Ryan, attorneys; Thomas N. Ryan and
    Jessica A. Jansyn, on the brief).
    JUSTICE ALBIN delivered the opinion of the Court.
    1
    Defendant Township of Sparta (Township) passed a resolution imposing
    a special assessment on fifty-eight properties to recoup public funds expended
    in the rehabilitation of a private dam owned by the Glen Lake Beach Club, Inc.
    (Beach Club). Under the Beach Club’s bylaws, the owners of the fifty-eight
    properties -- all within close proximity to Glen Lake -- are eligible to join the
    Beach Club and enjoy its amenities.
    Eight of those property owners (plaintiffs) filed an action in lieu of
    prerogative writs challenging the validity of the special assessment. Plaintiffs
    are not members of the Beach Club, and they do not own properties either on
    the lake or with a view of the lake. They claimed that the special assessment,
    which allocates the costs for the restoration of the dam among the fifty-eight
    properties, was not in proportion to any benefit they received, thus violating
    N.J.S.A. 58:4-12(d)(1). Plaintiffs attacked the expert appraiser’s report relied
    on by the Township, asserting that it offered no methodology or justification
    for imposition of the assessment on their properties and therefore it constituted
    a “net opinion.”
    The trial court agreed. The court determined that the expert report did
    not follow any discernible methodology in allocating the cost for the dam
    restoration among plaintiffs’ properties and therefore declared the resolution
    imposing the special assessment arbitrary and void. The Appellate Division
    2
    reversed, finding within the four corners of the expert report a sufficient basis
    to justify the special assessment on plaintiffs’ properties, and reinstated the
    resolution.
    We come to a different conclusion than the Appellate Division.
    Although plaintiffs’ properties may have received a benefit from the dam
    restoration project, the expert report relied on by the Township did not apply
    any reliable methodology to assure that the assessment allocating the costs
    among the properties was “in proportion to and not in excess of the benefits
    conferred,” as required by N.J.S.A. 58:4-12(d)(1) and other statutes. The
    Legislature has delegated to municipalities the power to impose special
    assessments on property owners to fund certain improvements. That power,
    however, may not be arbitrarily exercised. The presumption of validity
    accorded to a municipal law cannot shield a special assessment based on a
    methodology that lacks any indicia of reliability. Accordingly, we are
    constrained to invalidate Sparta Township Resolution 6-1, which imposes a
    special assessment on plaintiffs’ properties to recoup the costs of the dam
    restoration project.
    We therefore reverse the judgment of the Appellate Division. The
    Township must pass a resolution allocating costs based on a valid
    methodology in accordance with the applicable statutes and relevant case law.

    I.
    A.
    The Glen Lake Beach Club -- a private club located in the Township of
    Sparta -- owns Glen Lake and the Glen Lake Dam, which impounds the water
    that forms the lake. The Beach Club offers various amenities to its members
    and their guests, such as boating, fishing, swimming, and social activities.
    Eligibility for membership in the Beach Club is governed by the organization’s
    bylaws. All owners of real estate within a specifically delineated perimeter
    near the lake known as the “reserve” -- as set forth in the Beach Club’s bylaws
    -- are automatically eligible for membership and voting rights, provided they
    apply for membership and satisfy the Club’s membership requirements.1
    Other Township residents who live outside of the “reserve” can apply for
    “special membership” in the Beach Club if sponsored by a voting member.
    Those residents granted special membership by the Beach Club’s governing
    body may enjoy all of the Club’s amenities but do not have voting rights.
    In the early 2000s, the New Jersey Department of Environmental
    Protection (NJDEP) classified the Glen Lake Dam as a “high hazard dam”
    requiring rehabilitation. To fund the repairs necessary for the dam to meet the
    1

    not changed since the 1970s.
    4
    state’s regulatory requirements, the Beach Club applied for and received a
    $725,000 loan from the NJDEP’s Dam, Lake and Stream Project Fund,
    N.J.S.A. 58:4-12. In accordance with N.J.S.A. 58:4-12(d)(1), the Township
    agreed to serve as a co-borrower on the loan. The co-borrower agreement
    between the Beach Club and the Township provided that the Beach Club
    would be responsible for repayment of the loan -- $925,726 in principal,
    interest, and related costs -- and the Township would act as the “collection
    agent” by passing an ordinance imposing a special assessment on “real estate
    in the Township benefitted by [the dam] improvement.”
    In February 2016, the Township Council enacted Ordinances 16-03 and
    16-04. Ordinance 16-03 authorized the Township to impose a special
    assessment on “the benefitted properties” of the dam project, and Ordinance
    16-04 established an Assessment Commission to identify the benefitted
    properties and to determine the assessment to be imposed on those properties.
    In March 2016, the Council appointed Scott Holzhauer, a real estate
    appraiser and consultant, to assist the Assessment Commission in fulfilling its
    charge. More than a year earlier, before his appointment, Holzhauer had
    submitted a written proposal to the Township setting forth a market-value
    approach in assessing the benefit that properties received from the dam project.
    Under that approach, the Township would appraise the market value of each
    5
    affected property before and after the dam rehabilitation project. The
    difference between the property’s market value before and after the project
    would represent the property’s enhanced value.
    In a report dated June 22, 2016, Holzhauer submitted his consulting
    report to the Assessment Commission. Holzhauer identified fifty-eight
    properties that benefitted from the Glen Lake Dam Rehabilitation Project. He
    recommended that those properties be subject to the special assessment to
    repay the loan received from the NJDEP’s Dam, Lake and Stream Project
    Fund. The fifty-eight properties that Holzhauer proposed for the special
    assessment came from a list of sixty-five properties that fell within the Beach
    Club’s “reserve,” an area near the lake delineated in the organization’s
    bylaws.2 Seven of the sixty-five properties were exempt from the special
    assessment for various reasons, such as by the terms of the co-borrower
    agreement or the NJDEP loan agreement. The owners of the fifty-eight other
    properties were eligible for voting membership in the Beach Club, even though
    a number had chosen not to become Club members.
    Holzhauer’s report acknowledged that, by statute, the special assessment
    on the fifty-eight properties must be proportionate to “and not in excess of the
    2

    peculiar benefit, advantage or increase in value” from the dam project , quoting
    N.J.S.A. 40:56-27. The owners of the fifty-eight properties received a
    “peculiar benefit” or “advantage,” according to Holzhauer, because they have
    the option to become members of the Beach Club and to enjoy its recreational
    amenities. The report states that “[t]his benefit serves as an enhancement to
    property value for these property owners,” thus distinguishing them from
    property owners outside the “reserve,” except for those who had availed
    themselves of special membership. In explaining the reasons for imposing the
    special assessment on the properties within the “reserve,” the report states that
    “[o]wnership of property in a lake community . . . brings with it the
    expectation of recreational amenities and scenic views that each contribute to
    the value and desirability of the property.” The report adds, however, that
    those rewards must be balanced against the “risk” associated with the
    “survival” of a dam that “is generally crucial to property value for owners that
    have located within the lake community.”3
    Holzhauer devised an approach to allocate the special assessment by
    dividing the properties in the “reserve” into three separate categories:
    3
    The report noted that if the Beach Club did not undertake the dam
    rehabilitation project, then the NJDEP possessed the authority to do so under
    N.J.A.C. 7:20-2.9 and to recoup the costs by imposing a lien on the benefitted
    properties within the “reserve.”
    7
    (1) seven lakefront properties, (2) eleven lakeview properties with lake access,
    and (3) the forty remaining properties. In that three-tiered approach,
    Holzhauer assigned “share values” to each category, allocating the highest
    share value to lakefront properties (2.0), a lower value to lakeview/access
    properties (1.5), and the lowest value to all other properties (1.0). 4 The
    following chart sets forth the special assessment imposed on each class of
    property over a fifteen-year period -- the period required to accomplish the
    repayment of the loan:

    The “Reserve”
    Total Assessment To Be Collected From All Properties            $925,726
    Holzhauer’s report does not explain the methodology he followed in
    assigning the values to the three classes of property -- other than presenting his
    conclusion that the properties closest to the lake received the greatest benefit
    4
    The lakefront properties “enjoy unimpeded direct access to the lake, along
    with the potential for establishing lake edge improvements,” such as docks.
    The lake-access lots are located “immediately across the street from the lake,
    enjoying direct pedestrian access to the lake and generally unobstructed
    views.” The remaining properties -- assigned the lowest share value -- do not
    enjoy any of the direct benefits of lakefront and lake-access properties but
    have proximity to the lake and the option of joining the Beach Club.
    8
    from the dam rehabilitation project and that the properties further from the
    lake received a lesser benefit.
    After conducting a public hearing and considering public comments, in
    June 2016, the Assessment Commission recommended that the Township
    Council adopt Holzhauer’s “report and formulaic approach” in allocating the
    special assessment.
    During Township Council public meetings, a number of property owners
    in the Beach Club’s “reserve” expressed their objections to the proposed
    special assessment. The property owners made various complaints, for
    example, alleging that their deeds, including the chain of title, did not alert
    them to the potential of a special assessment; that the boundary lines of the
    1970s bylaws did not include some of the targeted properties; and that the
    bylaws had been amended in the 2000s to widen the perimeter of the “reserve.”
    Sylvia Cappadora stated that, although the Beach Club claimed that the
    property owners “had the ability to join the lake association,” she -- a thirty-
    four-year resident of the “reserve” -- had been told when she attempted to join
    that the Club was not taking new members.
    Despite opposition from some residents, on August 23, 2016, the
    Township Council passed Resolution 6-1, adopting the recommendations made
    9
    in Holzhauer’s report, including the special assessment of $925,726 to be
    collected from the fifty-eight property owners in the Beach Club’s “reserve.”
    B.
    On September 12, 2016, plaintiffs Carol Crispino, Vilma Verber, Mark
    Edwards, Jorge Cabrera, Stephen Cappadora, Paul O’Keefe, Kenneth Gardner,
    and Mary Gardner filed an action in lieu of prerogative writs in Superior Court
    challenging the validity of Resolution 6-1. In their complaint, plaintiffs
    alleged that the Township Council failed to conduct a fair-market-value
    analysis to determine whether their properties received a “benefit” from the
    dam rehabilitation project, or the extent of any such benefit, and arbitrarily
    placed their properties “in the assessment area.” Plaintiffs claimed that,
    without some showing that the project conferred a “benefit” on their
    properties, the special assessment violated N.J.S.A. 40:56-27, and therefore
    Resolution 6-1 should be declared void. 5
    5
    The complaint also alleged other bases for striking down Resolution 6-1: a
    councilperson’s purported conflict of interest that tainted the Township
    Council proceedings, as well as purported violations of the Open Public
    Meetings Act and the Open Public Records Act. Although we granted
    certification on the conflict-of-interest issue, it is not relevant to our
    disposition of this appeal and therefore we need not reach it. Nor in this
    procedural history will we discuss other issues raised in plaintiffs’ complaint
    that were decided by the trial court and Appellate Division.
    10
    C.
    In a hearing before the Honorable Stuart A. Minkowitz, A.J.S.C., the
    parties relied on various submissions, such as the Beach Club’s bylaws, the
    minutes of the Township Council meetings, and the Holzhauer report. In a
    written opinion, Judge Minkowitz voided Resolution 6-1, reasoning that the
    Township arbitrarily applied the special assessment to plaintiffs’ properties.
    In reaching that decision, the court acknowledged the presumption of
    validity that attaches to municipal action. The court, however, recognized that
    a Township cannot levy a special assessment on property owners for a local
    improvement unless the improvement confers some benefit on the assessed
    property, in accordance with N.J.S.A. 40:56-27. The court noted that the
    Township Council relied on the Holzhauer report in passing the special
    assessment, but the report “did not use any stated methodology for deciding
    which houses would be burdened by the special assessment.” Although
    Holzhauer did not have to use a “fair market value benefit analysis,” the court
    declared that the expert had “to apply a non-arbitrary methodology” to justify
    imposing a special assessment on plaintiffs’ properties. The court found that
    Holzhauer’s reliance on the Beach Club’s bylaws to decide the reach of the
    special assessment ceded to a private entity the “indiscriminate power” to
    11
    amend its bylaws to include, if it chose, the entire Township to contribute to
    the assessment -- a “ludicrous result” in the court’s view.
    Judge Minkowitz compared the Holzhauer report to a “net opinion” -- an
    opinion resting “on unfounded speculation and unquantified possibilities,”
    quoting Townsend v. Pierre, 
    221 N.J. 36
    , 55 (2015). The court concluded that,
    in imposing the special assessment, the Township’s reliance on an expert
    report devoid of any meaningful methodology was “arbitrary and
    unreasonable.” The court held that “[t]he Township must begin the special
    assessment process anew, using an expert report that relies on . . . factual bases
    and a methodology that is reliable and not arbitrary,” citing
    ibid. In denying the
    Township’s motion for reconsideration, the court further
    elaborated that the Holzhauer report did not show that the properties subject to
    the special assessment -- based on the Beach Club’s bylaws -- “would receive
    a benefit from the Project, simply because those properties were eligible for
    membership.” Nor had the Township shown, the court stated, that
    “membership even had value.”
    D.
    In an unpublished opinion, the Appellate Division reversed the trial
    court’s voiding of Resolution 6-1. It determined that the Township Council
    properly relied on the methodology in the Holzhauer report and that the
    12
    Council’s adoption of Resolution 6-1 and the accompanying special
    assessment “was neither arbitrary nor unreasonable.”
    The Appellate Division rejected the notion that the rules of evidence
    apply to proceedings before a municipal body considering the imposition of a
    special assessment, quoting N.J.R.E. 101(a)(4) (stating that “proceedings
    before administrative agencies shall not be governed by [the rules of
    evidence],” with the exception of the rule governing privileges). “On that
    basis alone,” the Appellate Division reasoned, the trial court erred in applying
    “the net opinion rule to bar Holzhauer’s unrefuted methodology.”
    Assuming that the net opinion rule applied, the Appellate Division was
    satisfied that Holzhauer’s report “sets forth the ‘why’ and ‘wherefore’ of his
    methodology.” It did not discern any arbitrariness in imposing a special
    assessment on plaintiffs’ properties, given that they received, under N.J.S.A.
    40:56-27, a “peculiar benefit” or “advantage” from the dam rehabilitation
    project due to their “proximity to the lake and [the] recreational amenities
    [available] ‘through optional membership.’” The Appellate Division
    concluded that plaintiffs had failed to demonstrate “by clear and convincing
    evidence[] that the challenged decision was not ‘just and fair,’” quoting
    N.J.S.A. 40:56-54.
    We granted plaintiffs’ petition for certification. 
    239 N.J. 600
    (2019).

    II.
    A.
    Plaintiffs argue that the Township’s imposition of a special assessment
    on their properties, which they allege received no benefit from the dam
    rehabilitation project, was arbitrary and unreasonable. Plaintiffs describe
    themselves as property owners who fall within the Beach Club’s “reserve”
    only by the grace of the Club’s bylaws. They state that (1) they have “no lake
    view or lake access except by crossing a very busy road”; (2) though eligible
    to join this private Club, they have chosen not to do so; (3) they purchased
    their homes with no obligation to pay Beach Club fees; and (4) “they never
    expected to be burdened with a special assessment to repair a dam owned by
    . . . a private club, to which they did not belong.”
    Plaintiffs emphasize that the possibility or eligibility for membership in
    a private beach club is not an “actual benefit” under the relevant statutes and
    that the true test of whether they received a benefit from the dam project is any
    difference in the market value of their properties before and after the project’s
    completion. Plaintiffs point out that, during a Township Council meeting, one
    homeowner within the “reserve” asserted that she was denied membership in
    the Beach Club when she attempted to join. Plaintiffs complain not only that
    their properties were chosen for the special assessment by a random selection
    14
    -- inclusion in the Beach Club’s bylaws -- but also that the Township made no
    showing that the approximately $1000 annual assessment over fifteen years
    was proportionate to any benefit conferred.
    In sum, plaintiffs submit that the Appellate Division erred in upholding
    Resolution 6-1 without any proof that the dam project benefitted their
    properties or that the special assessment was in proportion to any benefit
    received, as required by N.J.S.A. 58:4-12(d)(1) and N.J.S.A. 40:56-27.
    B.
    The Township counters that the Holzhauer report provided the Township
    with a sufficient basis to impose the special assessment on plaintiffs’
    properties. According to the Township, plaintiffs’ eligibility to become
    members of the Beach Club since at least 1979 was a “benefit” under N.J.S.A.
    58:4-12(d)(1). From the Township’s perspective, the Beach Club had
    conferred on plaintiffs “the unique benefit of the ability to manage and control
    the lake, dam, and associated facilities.” The Township contends that, in
    determining the amount of the assessment, it was not required to analyze
    whether the market value of plaintiffs’ properties increased as a result of the
    dam project. It asserts that the standard governing public improvements,
    N.J.S.A. 40:56-27, which refers to “increase in value,” is different from the
    “more flexible standard” governing private dam improvements, N.J.S.A. 58:4-
    15
    12(d)(1), which refers to “benefits conferred.” The true test, the Township
    maintains, is whether the special assessment when measured “against the real
    estate benefited [is] thereby in proportion to and not in excess of the benefits
    conferred,” quoting N.J.S.A. 58:4-12(d)(1).
    The Township rejects plaintiffs’ use of an unsworn statement made by a
    homeowner within the “reserve” during a Township Council meeting to
    support the proposition that plaintiffs did not necessarily have the option to
    join the Beach Club. The Township claims that plaintiffs have presented a
    “moral argument,” not a legal one, “that only current [Beach Club] members
    should be ‘saddled’ with the cost of the dam improvements.” It submits that
    “limiting the assessment to current members could result in the perverse
    incentive for members to withdraw, leaving no one managing or running the
    club and, more importantly, no one to pay for the dam improvements, which
    benefitted real estate.”
    For those reasons, the Township urges that we affirm the Appellate
    Division.
    III.
    The issue before us is whether Sparta Township Resolution 6-1, which
    imposed a special assessment on plaintiffs’ properties for the repayment of a
    publicly funded loan that financed the rehabilitation of a dam owned by a
    16
    private lake club to which plaintiffs did not belong, complies with N.J.S.A.
    58:4-12 and other state laws.
    We begin with the well-established principle that municipal legislation
    enjoys a presumption of validity, and that courts will not invalidate an
    ordinance that bears a rational relationship to a legitimate objective and is not
    arbitrary or unreasonable. See N.J. Shore Builders Ass’n v. Township of
    Jackson, 
    199 N.J. 38
    , 54-55 (2009). Plaintiffs and the Township dispute
    whether Resolution 6-1 complies with state law. Our first task is to identify
    the state laws that govern the municipal action in this case.
    A.
    After the NJDEP determined that the Glen Lake Dam needed to be
    rehabilitated because of its hazardous condition, the Beach Club looked to the
    Dam, Lake and Stream Project Fund, N.J.S.A. 58:4-12, to finance the project.
    The Legislature enacted the Dam, Lake and Stream Project Fund to
    provide a financial source for the restoration and repair of private dams
    without burdening municipal capital budgets. See N.J.S.A. 58:4-11 and -12.
    The Fund provides a means for the owner of a private dam, such as a lake club
    or association, to secure a loan for the rehabilitation project. N.J.S.A. 58:4-12.
    To ensure repayment of the loan, N.J.S.A. 58:4-12 provides for a private and
    public partnership between the Beach Club and the Township -- with the
    17
    Township acting as the collector of the debt through the use of its municipal
    power to assess properties benefitted by the project.
    To that end, N.J.S.A. 58:4-12(d)(1) states:
    Loans awarded under this section to owners of private
    dams or lake associations shall require local
    government units to act as co-applicants. The cost of
    payment of the principal and interest on these loans
    shall be assessed, in the same manner as provided for
    the assessment of local improvements generally under
    chapter 56 of Title 40 of the Revised Statutes, against
    the real estate benefited thereby in proportion to and not
    in excess of the benefits conferred, and such assessment
    . . . shall be a first and paramount lien upon the real
    estate assessed to the same extent, and be enforced and
    collected in the same manner, as assessments for local
    improvements.
    [(emphases added).]
    For our purposes, N.J.S.A. 58:4-12(d)(1) provides two important
    features: (1) the cost of an improvement funded under this section must be
    assessed “in the same manner as provided for the assessment of local
    improvements generally under chapter 56 of Title 40 of the Revised Statutes ,”
    and (2) the assessment against the properties benefitted must be “in proportion
    to and not in excess of the benefits conferred.” The plain language of the
    statute makes clear that the Legislature intended to incorporate the law
    governing the special assessments for local improvements under Title 40 into
    18
    Title 58’s assessment for private dam and lake improvements financed by
    public funds.
    By that act of incorporation, the Legislature did not have to repeat the
    procedural and substantive standards for the imposition of an assessment
    already set forth comprehensively in Title 40. Significantly, nothing in Title
    40 is in conflict with the provisions of N.J.S.A. 58:4-12, including the
    requirement that property assessed be benefitted by the improvement and that
    the assessment be proportional to the benefit conferred.
    The Township understood that the special assessment process was
    governed by both Title 58 and Title 40. For example, the co-borrower
    agreement between the Beach Club and Township stated that “[t]he cost of the
    payment of the principal and interest on the Loan may be assessed, pursuant to
    the Special Assessment Ordinance in accordance with N.J.S.A. 58:4-12 et seq.,
    N.J.A.C. 7:24A-1.1 et seq., and N.J.S.A. 40:56-1.” Additionally, Ordinance
    16-03 authorized the Township to impose a special assessment “against the
    benefitted properties, pursuant to N.J.S.A. 40:56-1 et seq. and N.J.S.A. 58:4-
    12 et seq. in accordance with the Special Assessment statutes including but not
    limited to N.J.S.A. 40:56-27.” Ordinance 16-04 established the Board of
    Assessment Commissioners “in accordance with N.J.S.A. 40:56-1 et seq.,” to
    assist the Township Council, evidently because N.J.S.A. 58:4-12 makes no
    19
    provision for a Board of Assessment Commissioners. Finally, the Holzhauer
    report, which the Township Council adopted, expressly relied on and quoted
    from N.J.S.A. 40:56-27 in determining and identifying the benefitted
    properties.
    We therefore turn to the procedural and substantive standards set forth in
    Title 40 governing the imposition for assessments on properties benefitted by
    local improvements. See N.J.S.A. 40:56-1 to -64. “A local improvement is
    one, the cost of which, or a portion thereof, may be assessed upon the lands in
    the vicinity thereof benefited thereby.” N.J.S.A. 40:56-1 (emphasis added). A
    municipality is authorized to appoint “commissioners to make the assessments
    for benefits for [a local] improvement,” N.J.S.A. 40:56-22, and those
    commissioners are empowered to “make a just and equitable assessment of the
    benefits conferred upon any real estate by reason of [the local] improvement
    having due regard to the rights and interests of all persons concerned, as well
    as to the value of the real estate benefited,” N.J.S.A. 40:56-26.
    N.J.S.A. 40:56-27 describes in detail how the assessment must relate to
    the benefit received:
    All assessments levied under this chapter for any local
    improvement shall in each case be as nearly as may be
    in proportion to and not in excess of the peculiar
    benefit, advantage or increase in value which the
    respective lots and parcels of real estate shall be
    deemed to receive by reason of such improvement.
    20
    We do not discern any real distinction between the language above and
    N.J.S.A. 58:4-12(d)(1)’s language stating that the imposition of an assessment
    on property must be “in proportion to and not in excess of the benefits
    conferred” by the dam improvement. Title 40 also sets forth procedural
    guideposts. For instance, “[a]ll assessments for local improvements shall be
    presumed to have been regularly assessed and confirmed . . . until the contrary
    be shown,” N.J.S.A. 40:56-33, and ultimately a reviewing court must
    determine whether the assessment is “just and fair,” N.J.S.A. 40:56-54; see
    also 2nd Roc-Jersey Assocs. v. Town of Morristown, 
    158 N.J. 581
    , 597 (1999)
    (stating that special “assessments are ‘presumptively correct and the taxpayers
    [have] the burden of overcoming that presumption by clear and convincing
    evidence’” (alteration in original) (quoting McNally v. Township of Teaneck,
    
    75 N.J. 33
    , 44 (1977))).
    Because N.J.S.A. 58:4-12(d)(1) incorporates the provisions of Title 40
    that relate to “the assessment of local improvements” and because this is our
    first occasion to address N.J.S.A. 58:4-12(d)(1), the case law construing the
    relevant provisions of Title 40 offers guidance.
    B.
    The justification for any special assessment levied for the purpose of
    financing a local improvement, N.J.S.A. 40:56-27, or an improvement to a
    21
    privately owned dam, N.J.S.A. 58:4-12, is that the assessed property has
    received a benefit from the improvement. See Gabriel v. Borough of Paramus,
    
    45 N.J. 381
    , 384 (1965) (“The foundation of the power to levy a special
    assessment is the benefit or enhancement of value which the improvement
    confers.”). Special assessments may be imposed on properties for such local
    improvements as the installation of sewage and water lines, street paving and
    curbing, and construction of parking facilities. See N.J.S.A. 40:56-1 and -1.1;
    see also 2nd Roc-Jersey 
    Assocs., 158 N.J. at 604
    (upholding a special
    assessment of commercial properties within a special improvement district). If
    there is no “peculiar benefit, advantage or increase in value” to the property
    from the improvement, then there is no basis for imposing an assessment. See
    N.J.S.A. 40:56-27.
    The benefit to the assessed property “must be certain rather than
    speculative, although it may arise in the future.” 2nd Roc-Jersey 
    Assocs., 158 N.J. at 593-94
    (noting that an assessment for an improvement is proper even if
    “the benefit is not presently apparent”). “The fact that a landowner has no
    present, immediate use for the improvement is . . . immaterial, so long as the
    use of the improvement is accessible and available to the land sought to be
    assessed for any use to which the property may legitimately be put.”
    Ridgewood Country Club v. Borough of Paramus, 
    55 N.J. 62
    , 68-69 (1969).
    22
    Ordinarily, “the benefit to the specific property must be substantially greater
    than to the public in general.” 2nd Roc-Jersey 
    Assocs., 158 N.J. at 592-93
    .
    An assessment, moreover, must be proportionate to the benefit conferred
    on the property. The proportionality requirement is measured by a standard of
    reasonableness, not by scientific precision. See N.J.S.A. 58:4-12(d)(1) (“in
    proportion to . . . the benefits conferred”); N.J.S.A. 40:56-27 (“as nearly as
    may be in proportion to”); 2nd Roc-Jersey 
    Assocs., 158 N.J. at 596
    . “So long
    as [the] owner is required to pay [no] more than the benefit received and the
    method of determining the amount of that benefit is reasonable and appli ed
    uniformly to all property owners, the statutory mandate has been satisfied.”
    
    McNally, 75 N.J. at 46
    .
    The test often used to determine the value of the benefit and the amount
    of the assessment is “the difference between the market value of the land
    before and after the improvement.”
    Id. at 42;
    see also McQueen v. Town of
    West New York, 
    56 N.J. 18
    , 23 (1970) (stating that the “‘[b]enefit’ is the
    increment of value to land affected by improvement. It represents the
    difference between the market value of the lands before the improvement and
    the market value of the land immediately after the improvement” (quoting In
    re Pub. Serv. Elec. & Gas Co., 
    18 N.J. Super. 357
    , 365 (App. Div. 1952))).
    23
    Nevertheless, no inflexible formula applies, nor is “mathematical
    precision” required. See 2nd Roc-Jersey 
    Assocs., 158 N.J. at 596
    , 601;
    
    McQueen, 56 N.J. at 24
    . Another assessment methodology may be used, so
    long as the result is a “just and equitable assessment of the benefits conferred.”
    
    McQueen, 56 N.J. at 24
    ; see also 2nd Roc-Jersey 
    Assocs., 158 N.J. at 601-02
    (finding that “[t]he method of assessment must necessarily be adapted to the
    benefit conferred” and that other methods that are “just and equitable” or
    “rational and appropriate” may be used). Although a fair-market-value
    approach may be suitable for an improvement such as the installation of a
    water or sewage line, see Ridgewood Country 
    Club, 55 N.J. at 68-71
    , it may
    not be suitable for determining the benefit to commercial properties located
    within a special improvement district, see 2nd Roc-Jersey Assocs., 158 N.J
    601-02 (noting that the standard fair-market-value approach was not applicable
    because “the nature of the benefit [was] general and intangible, and the
    quantum of the benefit [was] imprecise”).
    The value of the benefit conferred on the assessed property by the
    improvement must be “established by the conventional method of expert
    testimony or by some other reliable proof.” See 
    McNally, 75 N.J. at 42
    (emphasis added) (citing 
    McQueen, 56 N.J. at 24
    ). To state the obvious, a
    municipality cannot impose an assessment based on an arbitrary methodology.
    24
    See Ridgewood Country 
    Club, 55 N.J. at 69-70
    (finding that the assessment
    was “arbitrary and unreasonable” because the record did not contain “proof by
    any qualified witness of any such net dollar enhancement in value”).
    IV.
    The Holzhauer report, which was adopted by the Assessment
    Commission and the Township Council, did not comport with the statutory
    mandates and the governing case law. Holzhauer did not apply a fair-market-
    value methodology to determine the value of the subject properties before and
    after the dam improvement, as he stated in his proposal letter to the Township. 6
    Although Holzhauer and the Township were not bound to follow the traditional
    fair-market-value approach, they were required to employ a rational and non-
    arbitrary methodology.
    6
    Holzhauer stated that his report would
    contain valuation information for each property (base
    land value with and without consideration of the dam
    improvement), . . . the identification of each property,
    purpose and function of the appraisal report, date of
    valuation, identification of property rights appraised,
    neighborhood characteristics, zoning, site data, highest
    and best use conclusion, a discussion of the appraisal
    technique(s) considered and used in the valuation
    process, a presentation of comparable market data for
    each approach considered, and a reconciliation of the
    data into two separate estimates for each property as of
    the appraisal date.
    25
    Holzhauer simply concluded that property owners listed within the
    geographical ambit of the Beach Club’s bylaws received a “benefit” because of
    “their right, by property ownership and/or interest, to become a member of the
    club and therefore have access to the lake and other amenities.” Plaintiffs
    suggest that the Beach Club randomly placed their properties in the “reserve,”
    pointing to properties an equal distance from the lake, whose owners are not
    automatically eligible for membership in the Beach Club. Surely, if
    membership eligibility increased the value of property, that seemingly would
    indicate an ascertainable and tangible benefit, even to plaintiffs, none of whom
    were members of the Beach Club or intended to become members. But
    Holzhauer did not conduct any analysis showing that plaintiffs’ outer-rim
    properties received such a benefit because of Beach Club eligibility.
    Additionally, there is lack of certainty whether all property owners
    within the Beach Club “reserve” are, in fact, automatically eligible for
    membership. One property owner spoke out at a Township Council meeting,
    stating that she was denied membership because she was told the Club was not
    taking any new members. Certainly, if an assessment were premised on
    membership eligibility, the Township Council should have resolved the issue
    of whether membership in the Beach Club was automatic for property owners
    within the “reserve” who applied for and accepted the terms of membership.
    26
    Indeed, the trial court suggested at the action in lieu of prerogative writs
    hearing that exposure of a property owner to an assessment because of
    presence within the “reserve” might even hinder the marketability of property. 7
    Such questions arise here only because of the lack of a market-value study or
    some other reliable methodology establishing that plaintiffs received a “certain
    rather than [a] speculative” benefit. See 2nd Roc-Jersey 
    Assocs., 158 N.J. at 593
    .
    Even if we assume that plaintiffs were eligible to become members of
    the Beach Club and that such membership conferred on them a benefit from
    the dam restoration project, the Holzhauer report does not set forth a rational
    methodology for the assessments imposed on plaintiffs’ properties. Holzhauer
    assumed that lakefront properties received the greatest benefit, lake
    view/access properties a lesser benefit, and all other properties furthest from
    the lake and in the “reserve” the least benefit. That assumption has some
    logical and perhaps facial appeal. But Holzhauer did not explain how he
    arrived at assigning value shares to each category or how he came to the result
    7
    During the public comment period before the Township Council, one
    property owner within the “reserve” stated that he had purchased his property
    several months earlier and had just received the approximately $14,000
    assessment bill for the dam project -- an additional cost of which he was
    unaware when he had purchased his home. For that reason, he asked the
    Township Council to exclude his property from the assessment.
    27
    that the fifteen-year special assessment for lakefront properties is $26,263
    (value share 2.0), lake view/access properties is $19,967 (value share 1.5), and
    all other properties is $13,131 (value share 1.0). Holzhauer did not refer to
    any reliable methodology to support his opinion. Special assessments cannot
    be imposed on properties based on arbitrary categorizations or speculative
    valuations.
    Although we do not import the “net opinion” rule used in court
    proceedings into this municipal/administrative setting, that rule simply stands
    for the proposition that an expert opinion must have a rational basis.
    
    Townsend, 221 N.J. at 53-54
    . For that reason, the “net opinion” rule “forbids
    the admission into evidence of an expert’s conclusions that are not supported
    by factual evidence or other data.”
    Ibid. (quoting Polzo v.
    County of Essex,
    
    196 N.J. 569
    , 583 (2008)). Experts must “‘give the why and wherefore’ that
    supports the opinion, ‘rather than a mere conclusion.’”
    Id. at 54
    (quoting
    Borough of Saddle River v. 66 E. Allendale, LLC, 
    216 N.J. 115
    , 144 (2013)).
    The general conception of the “net opinion” rule has long guided our
    local improvement assessment jurisprudence, which requires that a special
    assessment be founded on “expert testimony or by some other reliable proof,”
    see 
    McNally, 75 N.J. at 42
    , or “proof by any qualified witness” that is not
    “arbitrary or unreasonable,” see Ridgewood Country 
    Club, 55 N.J. at 70
    .
    28
    The Holzhauer report did not address in any meaningful way the
    statutory requirements -- that the special assessment imposed on plaintiffs’
    properties for the dam rehabilitation project be “in proportion to and not in
    excess of the benefits conferred,” see N.J.S.A. 58:4-12(d)(1), or “be as nearly
    as may be in proportion to and not in excess of the peculiar benefit, advantage
    or increase in value . . . by reason of [the dam] improvement,” see N.J.S.A.
    40:56-27.
    Ultimately, it is the role of our courts to “determine whether or not the
    assessment . . . is a just and fair assessment,” see N.J.S.A. 40:56-54, after
    giving due regard to the presumption of validity that attaches to the municipal
    action in this case, see N.J.S.A. 40:56-33.
    The Holzhauer report, on which the Township relies, does not set forth
    any methodology or any sound analysis to justify the special assessment
    imposed on plaintiffs’ properties. We therefore conclude that the presumption
    of validity accorded to Resolution 6-1 has been overcome by clear and
    convincing evidence. See 2nd Roc-Jersey 
    Assocs., 158 N.J. at 597
    . Because
    the special assessment cannot be sustained based on the record before us, we
    must invalidate Resolution 6-1 as an arbitrary and unreasonable law.
    29
    V.
    For the reasons explained, we reverse the judgment of the Appellate
    Division. We remand this matter to the Sparta Township Council to start anew
    the process of establishing a special assessment for the repayment of the loan
    that funded the dam rehabilitation project -- guided by the applicable statutes
    and the opinion of this Court.
