    PURE WAFER V. CITY OF PRESCOTT                           3
    SUMMARY*
    Contract Clause
    The panel affirmed in part and reversed in part the district
    court’s permanent injunction in favor of plaintiff, entered
    following a bench trial, and remanded in an action brought
    under 42 U.S.C. § 1983 alleging that the City of Prescott,
    Arizona violated the Contract Clause of the Constitution
    when it declared that its sewage treatment plant would no
    longer accept wastewater discharged by plaintiff’s metal
    refinishing plant.
    This controversy centered on the fluoride concentration
    in plaintiff’s effluent, and the City’s enactment of an
    Ordinance imposing limits on such concentration. Plaintiff
    alleged that application of the Ordinance to plaintiff’s
    industrial wastewater discharges constituted an
    unconstitutional impairment of its contract rights, in violation
    of the Contract Clauses of the federal and state constitutions.
    Reversing the district court’s judgment on the Contract
    Clause claims, the panel held that the City had not impaired
    the obligation of its contract with plaintiff, because the
    Ordinance has not altered the ordinary state-law remedies to
    which plaintiff would otherwise be entitled if it successfully
    proved a breach of contract. The panel stated that the City
    might very well have breached its contract, but that did not
    necessarily mean it has violated the Contract Clauses of the
    federal and state constitutions.

    4           PURE WAFER V. CITY OF PRESCOTT
    The panel held that the judgment for plaintiff could be
    sustained on the alternative ground that the City breached its
    contract with plaintiff. The panel held that the City had
    previously agreed to accept such effluent as the parties knew
    plaintiff would need to discharge in order to maintain a viable
    business and that the City agreed to bear the financial risk
    that state-initiated regulatory changes would make complying
    with such promise more costly than it was when the parties
    entered into an agreement. The panel held that enforcing the
    Ordinance against plaintiff would eviscerate the benefit of
    plaintiff’s bargain; the City could not do so without putting
    itself in breach of the agreement. The panel stated that on
    remand the district court should decide the appropriate
    remedy. The panel further ordered that the district court’s
    injunction forbidding enforcement of the Ordinance against
    plaintiff would remain in effect during subsequent stages of
    litigation.
    Concurring in part and dissenting in part, Judge N.R.
    Smith concurred with the majority’s conclusion that plaintiff
    did not have a claim under the Contract Clause of the United
    States or Arizona constitutions. Judge Smith dissented from
    the majority’s sua sponte decision to reach plaintiff’s
    alternative claims that the City breached its agreement. Judge
    Smith stated that the circumstances warranted remand to
    permit the district court (or an Arizona court) the first
    opportunity to address the merits of the breach of contract
    claim.

    OPINION
    O’SCANNLAIN, Circuit Judge:
    We must decide whether the City of Prescott, Arizona
    violated the Contract Clause of the Constitution when it
    declared that its sewage treatment plant would no longer
    accept wastewater discharged by one of its customers, a large
    metal refinishing plant.
    I
    This dispute sees the City of Prescott at odds with Pure
    Wafer, Inc., a corporate resident of Prescott, over contract
    interpretation. Pure Wafer’s grievances run from the
    constitutional—the City has violated our nation’s
    fundamental charter—to the mundane—the City has betrayed
    specific promises the two made to each other during happier
    days.
    6           PURE WAFER V. CITY OF PRESCOTT
    A
    Pure Wafer runs a facility in Prescott for cleaning silicon
    wafers used by clients like IBM, Intel, and Motorola. Called
    “test and monitor wafers,” they play a crucial role in the
    production processes those companies employ to build
    microprocessors and computer chips. Pure Wafer performs
    what is called a “reclaim” service: its role is to remove oxide
    nitrites from the wafers after they pass through a given phase
    of the production process, clean them, polish them, and send
    them back to its clients so they can be reused later on. The
    wafers range in diameter from four inches to one foot.
    Pure Wafer does a large volume of business, running the
    36,000-square-foot Prescott facility twenty-four hours a day,
    seven days a week, at around ninety-five percent capacity.
    All that reclamation activity generates a lot of
    wastewater—up to 195,000 gallons per day, although in
    practice it has been less—which Pure Wafer then discharges
    into the City’s sewer lines. The sewer lines carry Pure
    Wafer’s effluent into the City’s Airport Water Reclamation
    Facility (“AWRF”), one of three City-owned wastewater
    treatment plants in Prescott that process and treat effluent
    from the City’s sewers. The AWRF then discharges treated
    effluent either to golf courses or into recharge basins to
    replenish the City’s aquifer.
    This controversy centers on the fluoride concentration in
    Pure Wafer’s effluent, and the City’s recent enactment of an
    Ordinance imposing limits on such concentration.
    PURE WAFER V. CITY OF PRESCOTT                   7
    B
    In 1997 the City entered into a contract, called the
    Development Agreement (“the Agreement”), with Pure
    Wafer’s predecessor in interest, a company called Exsil. In
    2007 Pure Wafer purchased Exsil and acquired all of its rights
    and obligations under the Agreement. Like the parties, we
    refer to both entities as “Pure Wafer” for simplicity’s sake.
    At the time of the Agreement, Pure Wafer owned plants
    in Sulphur, Oklahoma and San Jose, California. The
    Agreement was a way for the City to entice Pure Wafer to
    build its third facility in the Prescott Airpark, which the City
    expected would create jobs, stimulate economic activity, spur
    infrastructure improvements, and generate tax revenue. In
    exchange, the City agreed to provide Pure Wafer with the
    sewage infrastructure it needed to conduct its reclamation
    business, plus (among other things) tax and zoning breaks to
    make it easier for Pure Wafer to expand the facility if it so
    desired. Pure Wafer constructed the facility in 1997, and
    expanded it in 2002, at a total cost of roughly $35 million.
    C
    Three provisions of the Agreement have figured centrally
    in the parties’ arguments during the course of this litigation.
    First, the Agreement’s section 4.2, together with Exhibit
    F, provide that the City may not raise Pure Wafer’s “sewer
    usage fees” above a certain rate schedule, so long as the
    fluoride content in Pure Wafer’s effluent remains at or below
    100 mg/L. Exhibit F recites that Pure Wafer’s fluoride
    content has a “typical” value of 50 mg/L and a “maximum”
    of 100 mg/L. In addition, Section 4.2 obligates the City to
    8            PURE WAFER V. CITY OF PRESCOTT
    provide up to 195,000 gallons of “sewer capacity” per day,
    and to bear the cost of “augment[ing] such facilities” as
    necessary to “accept or accommodate” Pure Wafer’s effluent.
    Second, section 9.1 provides that Pure Wafer “will
    operate the Facility . . . in accordance with all local, state, and
    federal environmental regulations.”
    Third, section 14.7, an integration clause, states that
    “[t]his Agreement and the exhibits hereto constitute the entire
    agreement between the parties,” “supersed[ing]” “all prior
    and contemporaneous agreements, representations,
    negotiations and understandings.”
    D
    Pure Wafer insists that when it negotiated the Agreement
    with the City, its most important objective was to make sure
    that its ability to operate the facility would not be thwarted by
    future changes in City regulations. As Pure Wafer tells it, it
    “didn’t want to . . . build a plant that could be . . . rendered
    useless at any time by the City,” and so it took precautions
    “to make sure that it had a locked up contract and a position
    on water, sewer and effluent requirements.” To that end,
    Pure Wafer claims that it “made sure that the City was fully
    aware of what [the facility’s] requirements were.”
    In particular, Pure Wafer avers that it was anxious to
    safeguard its ability to discharge effluent containing up to
    100 mg/L of fluoride, and Pure Wafer maintains that the City
    represented that discharging fluoride up to that level “would
    be acceptable.” In fact, earlier in the negotiations Pure Wafer
    had informed the City that its fluoride levels sometimes ran
    as high as 150 mg/L, but at the City’s request, Pure Wafer
    PURE WAFER V. CITY OF PRESCOTT                     9
    agreed to design the Prescott facility so that its fluoride
    contents would not exceed 100 mg/L, a commitment reflected
    in the maximum fluoride value listed in the Agreement’s
    Exhibit F. In all the years it has run the Prescott facility, Pure
    Wafer’s discharges have never exceeded 100 mg/L in fluoride
    concentration, and have averaged about 40 mg/L.
    Pure Wafer’s representatives testified that the company’s
    concern over the prospect of fluoride regulation stemmed in
    part from its experience in San Jose, where it ran a
    reclamation facility prior to opening the one in Prescott. In
    the 1980s San Jose apparently passed an ordinance “similar”
    to the Prescott Ordinance at issue in this case, which required
    Pure Wafer to “put a lot of infrastructure in to deal with
    fluorides,” the cost of which prevented Pure Wafer from
    expanding the facility. The real problem, Pure Wafer
    explains, was that it had no Development Agreement with
    San Jose; so much the wiser, Pure Wafer continues, it took
    steps to “communicate[] [its] needs to the City of Prescott
    and . . . actually got it inputted into a Development
    Agreement, the contractual obligation.”
    For its part, the City also claims that it harbored concerns
    about effluent composition in general and fluoride levels in
    particular. As noted above, the City had balked at Pure
    Wafer’s initial report that its fluoride levels were sometimes
    as high as 150 mg/L. In addition, at public hearings prior to
    the Agreement’s adoption, City officials stated that Pure
    Wafer would be required to comply with City codes
    regarding pretreatment of effluent discharge. At that same
    meeting, a Pure Wafer representative reassured the public that
    the company “did not want to pollute the air, water and
    ground, [and] that a system would be designed that would
    10          PURE WAFER V. CITY OF PRESCOTT
    allow discharge from their plant to be pure enough to go into
    the city’s wastewater treatment plant.”
    E
    Subsequent changes in state and federal environmental
    regulations set off the chain of events leading to this
    litigation. Above all, in 1999 the Arizona Department of
    Environmental Quality (“ADEQ”)—the State’s
    environmental regulatory agency—required the City to obtain
    an Aquifer Protection Permit (“APP”), which, in turn,
    imposed a host of requirements on the City, including the
    requirement that any discharge exiting the City’s AWRF
    could no longer exceed 4.0 mg/L of fluoride, measured at the
    point of discharge from the AWRF.
    That was a big change. Prior to the ADEQ-imposed APP
    regime, the City operated the AWRF pursuant to a
    Groundwater Protection Permit, which only required the City
    to sample the groundwater monitoring wells in the recharge
    basins in the City’s aquifer, one or more steps downstream
    from the AWRF’s point of discharge.               Under the
    Groundwater Protection Permit, the fluoride concentration in
    the recharge basins could not exceed 4.0 mg/L. The
    important point is that the impact of Pure Wafer’s effluent on
    samples taken from the recharge basins is less pronounced
    than it is with respect to samples taken at the AWRF, for at
    least two reasons. First, the recharge basins take in effluent
    discharged from at least two different sources: not only from
    the AWRF, but also from the larger Sundog Wastewater
    Treatment Plant. The AWRF’s effluent has a higher fluoride
    concentration than Sun Dog’s, but the two streams of effluent
    are commingled in the recharge basins, diluting the relative
    importance of the AWRF’s fluoride levels. Second, some
    PURE WAFER V. CITY OF PRESCOTT                  11
    effluent leaving the AWRF is used to water golf courses and
    does not actually enter the recharge basins. Illustrating the
    combined importance of these circumstances, it appears that
    Pure Wafer’s effluent has basically had no effect on the
    fluoride concentration in the aquifer, as from 1997 through
    2013, the monitoring well readings consistently reported
    fluoride concentrations of less than 0.4 mg/L, or one tenth of
    the amount allowed under the Groundwater Protection
    Permit.
    ADEQ’s decision to shift the monitoring location to the
    AWRF’s point of discharge had serious consequences. In
    particular, the City represents that the AWRF, “like most
    publically owned treatment works, is not designed to remove
    fluoride and other types of industrial pollutants” from the
    wastewater that flows into it, and that, in turn, it sends along
    to the aquifer. The upshot is that, in order for the City to
    comply with the APP’s 4.0 mg/L fluoride limit at the
    AWRF’s point of discharge, one of two changes had to occur:
    either the AWRF must be equipped to remove fluoride from
    wastewater that enters it; or the fluoride content of
    wastewater must be reduced before it ever enters the AWRF.
    The latter option is known as “pretreatment.”
    F
    In 2004 ADEQ sent the City a Notice of Violation
    alleging seven dates during the previous year on which the
    AWRF’s fluoride levels exceeded the maximum allowed
    under the City’s APP. The Notice directed the City to
    “submit a written response describing the corrective actions
    that have been taken to resolve the violations.” In response,
    the City in 2005 began to develop a pretreatment program and
    12            PURE WAFER V. CITY OF PRESCOTT
    to explore what local fluoride limits would help ensure that
    the City complied with its APP.
    Nevertheless, when ADEQ conducted a “pretreatment
    compliance audit” of the City in 2007, it concluded that “[t]he
    City does not have valid control mechanisms in place to
    regulate the discharges” from the City’s two categorical
    industrial users, including Pure Wafer. ADEQ declared it
    “imperative” that the City “establish an approved
    pretreatment program.” Under state law, the City’s APP
    violations could result in ADEQ fining the City up to $25,000
    per day. A.R.S. § 49-262(C).
    In 2012 ADEQ issued another Notice of Violation to the
    City, which still had not established a pretreatment program.
    The basis of the violation was again excessive fluoride
    concentration in effluent discharged from the AWRF. This
    time the City and ADEQ entered into a Consent Order, which
    mandated that within thirty days the City “shall adopt and
    submit for ADEQ’s review and approval the Pre-Treatment
    Program.”
    G
    In due course, the City passed Ordinance No. 4856-1313
    in 2013.1 As relevant here, the Ordinance imposes limits on
    the pollutants that industrial users, like Pure Wafer, are
    permitted to discharge into the City’s sewer system. Most
    important for this case, the Ordinance declares that
    Significant Industrial Users (of which Pure Wafer is one)
    1
    Pure Wafer has not questioned the City’s authority to enact the
    Ordinance. The City relies on a state statute, see Ariz. Rev. Stat. § 49-
    391, as well as Article I, Section 3 of its own Charter.
    PURE WAFER V. CITY OF PRESCOTT                          13
    “shall not discharge or cause to be discharged at any entry
    point” to a publically owned treatment works, including the
    AWRF, “any wastewater containing in excess of” 16.3 mg/L
    of fluoride.2 The Ordinance also requires industrial users like
    Pure Wafer to get a permit from the City and, to the extent
    necessary, to “pretreat” their wastewater prior to
    discharge—that is, to ensure, at their own expense, that their
    wastewater complies with the 16.3 mg/L limit on fluoride
    concentration. The Ordinance threatens those who violate it
    with injunctive action, civil penalties, and criminal
    prosecution. ADEQ approved the City’s pretreatment
    program as established by the Ordinance.
    The City estimates that if it were required to pretreat
    wastewater entering the AWRF so that it complies with the
    APP’s fluoride limitations, it would cost the City $2.7 million
    in capital outlay and $8.5 million annually. Pure Wafer has
    not yet conducted a study, but its preliminary estimate
    suggested that pretreatment of its own effluent would require
    the company to spend $1 million to $4 million in capital
    outlay and $360,000 to $720,000 annually.
    H
    Not surprisingly, Pure Wafer was not pleased with such
    developments. Claiming that it will likely close the facility
    if forced to comply with the Ordinance, Pure Wafer brought
    this lawsuit against the City (and certain of its officers in their
    official capacities) under 42 U.S.C. § 1983, seeking
    declaratory and injunctive relief, or in the alternative,
    2
    It appears that there were or are at least six Significant Industrial
    Users in Prescott, including Pure Wafer. Each received an identical letter
    from the City directing them to comply with the Ordinance.
    14           PURE WAFER V. CITY OF PRESCOTT
    damages. Pure Wafer alleged that by enacting the Ordinance
    the City had “impair[ed] the obligation” of its contract with
    Pure Wafer, in violation of Article I, section 10 of the federal
    Constitution, as well as the analogous Contract Clause of the
    Arizona Constitution; and that the City, by enacting the
    Ordinance, had committed at least two different breaches of
    contract, as well as a breach of the implied covenant of good
    faith and fair dealing. The City counterclaimed for a
    declaratory judgment that the Agreement in fact obligated
    Pure Wafer to comply with the Ordinance.
    1
    The district court held a hearing on Pure Wafer’s motion
    for a preliminary injunction, which by consent of the parties
    the court converted into a trial on the merits, to be bifurcated
    into a liability phase and a damages phase. The parties also
    agreed that the City would not enforce the Ordinance against
    Pure Wafer during the pendency of this litigation, including
    any appeal.
    2
    After trial on the merits, the district court entered
    judgment for Pure Wafer, refusing to accept the City’s
    contention that the pretreatment ordinance is an
    environmental regulation of the sort Pure Wafer agreed to
    obey. Instead, believing the Ordinance to be a thinly veiled
    “cost-shifting regulation,” the district court held that the City,
    through the Ordinance, had impaired the obligation of its
    contract with Pure Wafer, in violation of the Contract Clauses
    PURE WAFER V. CITY OF PRESCOTT                            15
    of the federal and state constitutions.3 The district court
    awarded Pure Wafer a permanent injunction. The court
    declined to rule on Pure Wafer’s alternative claims for breach
    of contract and breach of the implied covenant of good faith
    and fair dealing, and deemed it unnecessary to proceed to the
    damages phase of the trial. In addition, the district court held
    that Pure Wafer was entitled to attorneys’ fees, but did not set
    an amount until several months later. The court denied the
    City’s counterclaim.
    3
    The City timely appealed the district court’s judgment.
    The district court had jurisdiction under 28 U.S.C. §§ 1331,
    1343, and 1367,4 and we have jurisdiction under 28 U.S.C.
    § 1291.
    II
    The City first argues that the district court erred in
    holding that the City, by enacting the Ordinance, had violated
    the Contract Clause. The Contract Clause of the Constitution
    declares that “No State shall . . . pass any . . . Law impairing
    the Obligation of Contracts.” U.S. Const. art. I, § 10, cl. 1.
    3
    The district court and both parties treat the Contract Clause of the
    Arizona Constitution, Ariz. Const. art. II, § 25, as identical in scope to its
    federal counterpart. Accordingly, like them, we confine our discussion to
    the federal Contract Clause.
    4
    Our Circuit has previously held that § 1983 provides individuals
    with a cause of action to assert violations of the Contract Clause. S. Cal.
    Gas Co. v. City of Santa Ana, 
    336 F.3d 885
    , 887 (9th Cir. 2003) (per
    curiam). We note an apparent split of authority on the question. See, e.g.,
    Crosby v. City of Gastonia, 
    635 F.3d 634
    , 640–41 (4th Cir. 2011).
    16          PURE WAFER V. CITY OF PRESCOTT
    The Contract Clause applies to contracts entered into by a
    State, Fletcher v. Peck, 10 U.S. (6 Cranch) 87, 135–39
    (1810), as well as by municipalities, and such contracts may
    be “impaired” within the meaning of the Clause by municipal
    ordinances as well as by state legislation, St. Paul Gaslight
    Co. v. City of St. Paul, 
    181 U.S. 142
    , 148 (1901).
    In order to decide whether the City can prevail over the
    district court’s judgment under the Contract Clause, it is
    necessary first to set forth the differences between a city or
    State’s breach of a contract, on the one hand, and a city or
    State’s impairment of such contract’s obligation, on the other.
    A
    The Agreement is a contract between a municipality and
    a private party. In disputes involving government contracts,
    it can sometimes be hard to tell whether the governmental
    entity has “impaired the obligation” of its contract or has
    simply breached its contract with the private party. But the
    distinction is crucial, not least because conflating the two
    concepts would risk making a federal constitutional case out
    of even the most garden variety public contract dispute,
    transforming the Contract Clause into a font of state contract
    law. See Horwitz-Matthews, Inc. v. City of Chicago, 
    78 F.3d 1248
    , 1250 (7th Cir. 1996) (“It would be absurd to turn every
    breach of contract by a state or municipality into a violation
    of the federal Constitution.”). In fact, the Supreme Court
    long ago rejected “the proposition that wherever it is asserted
    on the one hand that a municipality is bound by a contract to
    perform a particular act and the municipality denies that it is
    liable under the contract to do so, thereby an impairment of
    the obligations of the contract arises in violation of the
    Constitution of the United States.” St. Paul Gaslight Co.,
    PURE WAFER V. CITY OF PRESCOTT                    
    17 181 U.S. at 149
    . Such proposition, the Court explained,
    “amounts only to the contention that every case involving a
    controversy concerning a municipal contract is one of Federal
    cognizance, determinable ultimately in this court. Thus, to
    reduce the proposition to its ultimate conception is to
    demonstrate its error.” 
    Id. So how
    do we tell the difference between a government’s
    impairing the obligation of its contract and simply breaching
    it? At the most basic level, it cannot be said to have
    “impaired” the obligation of its contract if such “obligation”
    remains in full force and effect. And our cases establish that
    the “obligation” of a contract is the judicially enforceable
    duty it imposes upon each party either to perform or else to
    submit to the courts’ remedial powers, which will often take
    the form of an order to pay damages, but may encompass
    other remedies as well (and thus Holmes may have been too
    hasty in proclaiming that “[t]he duty to keep a contract at
    common law means a prediction that you must pay damages
    if you do not keep it, — and nothing else.” Oliver Wendell
    Holmes, Jr., The Path of the Law, 10 Harv. L. Rev. 457, 462
    (1897)).
    Given that principle, state action cannot be said to
    “impair” the obligation of a contract so long as it leaves both
    parties free to obtain a court-ordered remedy (typically
    damages) in the event that either of them fails to perform as
    promised. And that principle holds true whether state action
    affects a contract between private parties or, as here, a
    contract to which the State itself is a party. See, e.g., Univ. of
    Haw. Prof’l Assembly v. Cayetano, 
    183 F.3d 1096
    , 1102 (9th
    Cir. 1999) (“[T]he substantial impairment test turns on
    whether the State has used its law-making powers not merely
    to breach its contractual obligations, but to create a defense
    18           PURE WAFER V. CITY OF PRESCOTT
    to the breach that prevents the recovery of damages.”);
    
    Crosby, 635 F.3d at 642
    n.7 (“If the offended party retains the
    right to recover damages for the breach, the Contracts Clause
    is not implicated; if, on the other hand, the repudiation goes
    so far as to extinguish the state’s duty to pay damages, it may
    be said to have impaired the obligation of contract.”);
    
    Horwitz-Matthews, 78 F.3d at 1251
    (“The essence . . . of a
    breach of contract is that it triggers a duty to pay damages for
    the reasonably foreseeable consequences of the breach. If the
    duty is unimpaired, the obligation of the contract cannot be
    said to have been impaired.”).
    The Supreme Court’s Contract Clause cases likewise
    reflect the deep connection between obligation and remedy,
    the upshot being that a State does not “impair the obligation”
    of a contract so long as it leaves contracting parties free to
    pursue the ordinary state-law remedies in the event of breach.
    As the Court explained in General Motors Corp. v. Romein,
    “[t]he obligation of a contract consists in its binding force on
    the party who makes it.” 
    503 U.S. 181
    , 189 (1992) (quoting
    McCracken v. Hayward, 43 U.S. (2 How.) 608, 612 (1844)).
    Thus, a State may “trigger Contract Clause scrutiny” if it
    enacts “changes in the laws that make a contract legally
    enforceable,” for example, by eroding “the remedies available
    under a contract” in a way that “convert[s] an agreement
    enforceable at law into a mere promise.” 
    Id. But by
    contrast,
    a State does not violate the Contract Clause if its challenged
    action does “not change the legal enforceability of the . . .
    contracts,” 
    id. at 190,
    a condition a State satisfies so long as
    it does not purport to relieve a party—including, most
    PURE WAFER V. CITY OF PRESCOTT                         19
    especially, itself—of its duty either to perform or to submit to
    a court-ordered remedy.5
    In a similar vein, United States Trust Co. of New York v.
    New Jersey explained that “[c]ontract rights are a form of
    property and as such may be taken for a public purpose
    provided that just compensation is paid,” and thus “[t]he
    States remain free to . . . abrogate such contractual rights,
    upon payment of just compensation.” 
    431 U.S. 1
    , 19 n.16, 29
    n.27 (1977).
    B
    In light of the principles outlined above, it is clear to us
    that the City has not impaired the obligation of its contract
    with Pure Wafer, because the Ordinance has not altered the
    ordinary state-law remedies to which Pure Wafer would
    otherwise be entitled if it successfully proves a breach of
    contract. The City might very well have breached its
    contract—a question we discuss later in this opinion—but
    that does not necessarily mean it has violated the Contract
    Clause of the federal Constitution.
    5
    To be sure, the Contract Clause does not automatically approve state
    action that merely alters the remedies available on a contract but stops
    short of wiping them out entirely; as Justice Cardozo observed (with some
    understatement), the “dividing line” between obligation and remedy “is at
    times obscure,” and some purely remedial changes may be too “oppressive
    and unnecessary” to pass muster under the Contract Clause. W.B.
    Worthen Co. v. Kavanaugh, 
    295 U.S. 56
    , 60, 62 (1935). We need not
    linger over such difficulties, however, because as we explain, here the
    City has not attempted to tinker at all with the remedies Pure Wafer would
    be entitled to obtain in the event it proves a breach of contract.
    20            PURE WAFER V. CITY OF PRESCOTT
    Indeed, Pure Wafer included a claim for simple breach of
    contract in its suit against the City, alleging that “Pure Wafer
    cannot comply with the Ordinance without incurring
    substantial costs which the Development Agreement allocated
    to the City,” and specifically requested “such amount of
    damages as Pure Wafer may establish at any trial of this
    action as flowing from the City’s breach.”
    Crucially for our purposes here, the City has never
    asserted the Ordinance as a defense that would have the legal
    effect of discharging the City’s duty to perform and would
    thereby relieve the City of its legal obligation—established
    by the contract—to pay damages or some other remedy as a
    consequence of its non-performance.6
    But we need not speculate about what legal effect the
    Ordinance might have on Pure Wafer’s entitlement to judicial
    remedies, because the City has by now several times
    expressly represented that the Ordinance does not operate to
    dissolve (that is, impair) its binding obligation to perform
    whatever it promised to do under the Development
    Agreement. For instance, as the City put it in briefing
    following the district court’s hearing on Pure Wafer’s motion
    for a preliminary injunction:
    Pure Wafer . . . is suing the City in this case
    for breach of contract and is seeking money
    damages. . . . The City is defending this claim
    based upon the plain terms of the
    Development Agreement. If Pure Wafer
    6
    In fact, as noted above, the district court had ordered the trial
    proceedings bifurcated into a liability phase and a damages phase,
    something to which the City voluntarily agreed.
    PURE WAFER V. CITY OF PRESCOTT                           21
    prevails upon its breach of contract claims,
    the Court will presumably assess damages, to
    the extent damages are proven and
    appropriate. In any event, the Pretreatment
    Ordinance would not frustrate recovery.
    Likewise, at the hearing on Pure Wafer’s motion for a
    preliminary injunction, the City represented that “[t]his is a
    contract dispute as to what the Development Agreement
    between plaintiff and the city defendant provides. . . . It’s a
    garden-variety contract dispute. . . . They’re seeking
    damages for [the City’s] alleged breach of the contract. . . .
    They’re asking for damages if they have to comply because
    of the breach of contract. . . . The City can respond in money
    damages if it loses this case at the end of the day.”7
    Although the City has argued that the Ordinance survives
    Contract Clause scrutiny because any impairment was not
    substantial, the thrust of that argument was contract based,
    i.e. that Pure Wafer “agreed to comply with environmental
    regulations,” and that the “cost of regulatory compliance
    [was] not a term that was bargained for.” To the extent the
    City’s argument could be read otherwise, it should go without
    saying that the City is barred from altering its position on the
    legal effect of the Ordinance at subsequent stages in this
    litigation, thanks to the doctrine of judicial estoppel and
    related principles. See Whaley v. Belleque, 
    520 F.3d 997
    ,
    7
    We also note that the Agreement goes out of its way to state that
    “[i]n the event City is in default herein, [Pure Wafer] shall have all legal
    and equitable remedies available to it,” and further provides that the
    Agreement shall be enforceable “subject to a court’s equitable powers.”
    The City has not attempted to cast doubt on those provisions. Hence, in
    addition to damages, Pure Wafer may be able to request injunctive relief
    or specific performance if it so desires.
    22             PURE WAFER V. CITY OF PRESCOTT
    1002 (9th Cir. 2008); State v. Towery, 
    920 P.2d 290
    , 304
    (Ariz. 1996) (in banc).
    C
    The City’s analysis persuades us that Pure Wafer does not
    have a claim under the Contract Clause. This case has all the
    hallmarks of a quintessential contract dispute, and insofar as
    the City has attempted to refute Pure Wafer’s claimed rights
    under the Agreement—but has not attempted to render such
    rights legally unenforceable—it should be treated as a
    contract dispute. The district court’s judgment in favor of
    Pure Wafer’s Contract Clause claim cannot stand.
    III
    Nevertheless, Pure Wafer seeks to protect the judgment
    in its favor on the alternative claim that the City has simply
    breached the contractual obligations it undertook in the
    Development Agreement. Although the district court did not
    rule on this claim outright, it discussed the Agreement at
    length, considered extensive trial testimony, and made
    sufficient findings of fact and conclusions of law for us to
    resolve the scope of the parties’ contractual rights without
    need for a remand.8
    8
    Indeed, the district court itself recognized that “[t]he resolution of
    the issues in this case hinges on the nature and extent of the City’s
    obligations to accept Pure Wafer’s effluent under the terms of the
    Agreement.” Those same inquiries overlap substantially with our breach
    of contract analysis. Given that the district court, in its Contract Clause
    analysis, made sufficient findings of fact to conclude that the City had
    breached the contract, we disagree with the dissent that remand is
    necessary.
    PURE WAFER V. CITY OF PRESCOTT                            23
    We therefore proceed to the merits,9 mindful that with
    respect to any factual findings, “[i]f the district court’s
    account of the evidence is plausible in light of the record
    viewed in its entirety, the court of appeals may not reverse it
    even though convinced that had it been sitting as the trier of
    9
    The dissent argues that because “we have dismissed the only federal
    claim before us” we must remand the case back to the district court so that
    it might determine whether it should continue to exercise supplemental
    jurisdiction over the breach of contract claim under 28 U.S.C. § 1367(a).
    Dissent at 33–34. The district court had supplemental jurisdiction, as do
    we, because the Contracts Clause claim is a federal question. We
    respectfully disagree with our dissenting colleague.
    Section 1367(c) allows a district court to decline to exercise
    supplemental jurisdiction for one of four reasons. The district court could
    have invoked it and dismissed the state-law breach of contract claim at
    any time, but chose not to. And, nothing in this opinion precludes the
    district court from invoking § 1367(c) after we remand the case back to it.
    The dissent misreads § 1367(c)(3); it only applies when “the district court
    has dismissed all claims over which it has original jurisdiction.” (emphasis
    added).
    The dissent relies on cases such as Fang v. U.S. to argue we are
    improperly usurping the district court’s discretion. Dissent at 36–38
    (citing 
    140 F.3d 1238
    , 1240 (9th Cir. 1998)). But, we are reviewing a
    district court’s merit decision, not instructing the district court on whether
    to exercise supplemental jurisdiction. Fang involved a district court’s pre-
    trial dismissal of federal claims for lack of jurisdiction, and then a
    dismissal of related state claims pursuant to § 1367(c)(3). 
    Id. We reversed
    in that case, reinstating some of the federal claims and all of the
    state claims, but made clear the district court could reassess whether it
    should retain supplemental jurisdiction in the face of the defendant’s
    arguments that the state law claims raised novel issues of state law. 
    Id. at 1241–43.
    Here, we are not dismissing or reinstating any state law claims.
    The dissent’s real objection is that we reach the merits of the breach of
    contract issue—but that is a separate concern from whether we are
    usurping the district court’s § 1367(c) authority.

    The Development Agreement specifies that it “shall be
    governed by and construed under the laws of the State of
    Arizona.” The Arizona Supreme Court has made clear that
    “in Arizona, a court will attempt to enforce a contract
    according to the parties’ intent.” Taylor v. State Farm Mut.
    Auto. Ins., 
    854 P.2d 1134
    , 1138 (Ariz. 1993) (in banc).
    Moreover, under Arizona law, “a court may consider
    surrounding circumstances, including negotiation, prior
    understandings, and subsequent conduct.” 
    Id. at 1139.
    Further, courts applying Arizona contract law are not required
    to find ambiguity in the contractual language before they may
    entertain extrinsic evidence bearing on the parties’ intents.
    
    Id. at 1140.
    Rather, we are instructed “first [to] consider[] the
    offered evidence and, if [we] find[] that the contract language
    is ‘reasonably susceptible’ to the interpretation asserted by its
    proponent, the evidence is admissible to determine the
    meaning intended by the parties.” 
    Id. Such practice
    is
    permissible so long as the evidence “is being offered to
    explain what the parties truly may have intended.” 
    Id. B Pure
    Wafer’s theory is that the City promised to accept its
    effluent so long as its non-pretreated fluoride content remains
    at or below 100 mg/L, and to bear the financial risk of any
    future occurrence that would prevent the City from doing so,
    PURE WAFER V. CITY OF PRESCOTT                         25
    including future changes in law.10 To Pure Wafer’s mind, the
    Agreement gave it a “contractual . . . right to discharge at
    [contractually specified] rates up to 195,000 gallons per day
    of effluent containing up to 100 mg/L of fluoride,” and what
    is more, “[t]he parties agreed that . . . if it became necessary
    to modify the sewer system so as to permit Pure Wafer to
    discharge [such] effluent, the City would pay for that
    modification cost.” In Pure Wafer’s view, ADEQ’s
    inauguration of the APP regime has made it “necessary to
    modify the sewer system” in order to ensure Pure Wafer’s
    ability to discharge its effluent in the manner it believes the
    Agreement protects—and, Pure Wafer continues, recent
    regulatory changes are among the future contingencies whose
    risk the City agreed to shoulder. In other words, Pure Wafer
    believes it struck a bargain with the City which “allocated to
    the City the risk of potential future consequences of its
    acceptance of . . . Pure Wafer’s effluent,” including the risk
    that later-enacted legislation or regulation would require the
    City to pretreat such effluent as a condition of continuing to
    accept it.
    10
    The dissent contends that this breach of contract theory was never
    articulated by Pure Wafer in its Amended Complaint. Dissent at 40–41.
    It accuses us of inventing a new theory for Pure Wafer. Yet, Pure Wafer’s
    Amended Complaint articulates this theory several times. ¶¶ 3, 127, 142.
    Its two breach of contract claims incorporate preceding allegations and
    allege that by failing to exempt Pure Wafer from the Ordinance, as
    required by sections 9.2 and 14.4 of the Agreement, the City breached its
    contract. ¶¶ 149, 154. The logical conclusion from the Amended
    Complaint is that by trying to impose a new, lower discharge limit via the
    Ordinance, rather than exempting Pure Wafer, the City breached the
    Agreement. Of course, had the City exempted Pure Wafer it would not be
    in breach—a point no one contests.
    26          PURE WAFER V. CITY OF PRESCOTT
    Pure Wafer effectively describes the Agreement as a so-
    called “regulatory contract,” in which a “regulated entity
    contractually promises the government that [it] will provide
    or do something that is not otherwise clearly required by
    extant law. In return, the government contractually promises
    the regulated entity to maintain the regulatory regime set out
    in the contract. If the government breaches its promise of
    regulatory stability, it must pay contract damages.” David
    Dana & Susan P. Koniak, Bargaining in the Shadow of
    Democracy, 148 U. Pa. L. Rev. 473, 475 (1999).
    Such contracts are hardly novel. To take one prominent
    example, United States v. Winstar Corp. involved contracts
    between the federal government and certain thrift institutions,
    and the Supreme Court held that in such contracts the
    government had promised to regulate the thrifts in a specific
    manner, and to pay them damages if it later changed the
    regulatory landscape in a way that caused them financial
    harm. 
    518 U.S. 839
    , 871 (1996) (plurality opinion) (“The
    thrifts do not claim that the [federal government] purported
    to bind Congress to ossify the law in conformity to the
    contracts . . . . They simply claim that the Government
    assumed the risk that subsequent changes in the law might
    prevent it from performing, and agreed to pay damages in the
    event that such failure to perform caused financial injury.”);

    make”); 
    id. at 918
    (“The thrifts demonstrate that specific
    promises were made to accord them particular regulatory
    treatment for a period of years, which, when abrogated by
    PURE WAFER V. CITY OF PRESCOTT                          27

    (Scalia, J., concurring in

    are especially appropriate in the world of regulated industries,
    where the risk that legal change will prevent the bargained-
    for performance is always lurking in the shadows.” 
    Id. at 869
    (plurality opinion).12
    The contracts at issue in Winstar operated in the same
    manner as Pure Wafer alleges the Development Agreement
    operates here. That is, Pure Wafer claims that the Agreement
    requires the City to give it the benefit of (among other things)
    whatever fluoride regulations were in force at the time the
    Agreement was entered into, and that insofar as newly
    enacted laws (including the Ordinance) frustrate the City’s
    ability to do so, the City is in breach of the Agreement and
    must submit to whatever remedy the court deems appropriate.

    omitted)).
    28           PURE WAFER V. CITY OF PRESCOTT
    C
    The district court’s findings amply support Pure Wafer’s
    position. As the district court recounted, “Pure Wafer
    presented undisputed evidence that its operations require the
    discharge of effluent with a fluoride concentration above
    16.3 mg/L, that it expected at the time of the Agreement to be
    able to discharge at concentrations of up to 100 mg/L, that
    this right was critical to its negotiations based on its past
    experiences with its San Jose facility, and that the financial
    viability of the Prescott facility is threatened if it must bear
    the pretreatment costs.” Likewise, the district court
    concluded that “Pure Wafer was willing to incur the
    substantial initial capital investment to construct a reclaim
    facility in Prescott only if the City agreed to commit to
    maintaining water and sewer services to the facility at the
    specifications Pure Wafer needed to productively operate its
    facility,” and that “Pure Wafer need only establish that it has
    the right to discharge at least 100 mg/L, which it has done.”
    Although the district court did not use the phrase
    “regulatory contract” as we did above, the district court’s
    findings make unmistakably clear that the parties created
    such a contract. As the district court put it, the City cannot
    “force Pure Wafer to pay for pretreatment when the City has
    contractually agreed to not pass along such costs. The City
    must accept Pure Wafer’s effluent as-is and pretreat it at the
    City’s own expense.”
    We agree with the district court that the City agreed to
    accept such effluent as the parties knew Pure Wafer would
    need to discharge in order to maintain a viable business, and
    that the City agreed to bear the financial risk that State-
    initiated regulatory changes would make complying with
    PURE WAFER V. CITY OF PRESCOTT                          29
    such promise more costly than it was when the parties entered
    into the Agreement.13 Hence, the City may not force Pure
    Wafer to absorb the costs needed to bring the City into line
    with the terms of its APP. Enforcing the Ordinance against
    Pure Wafer would eviscerate the benefit of Pure Wafer’s
    bargain; the City cannot do so without putting itself in breach
    of the Agreement.
    Our conclusion is bolstered by representations the City
    itself made in a letter to ADEQ in the summer of 2004, in
    which the City explained that it had “signed an agreement
    with [Pure Wafer] on 2/11/97 allowing them to discharge
    Fluoride between 50 mg/l and 100 mg/l” into the City’s
    AWRF. And our conclusion derives further support from the
    district court’s finding that “[a]s early as 1994, ADEQ
    informed the City that its Groundwater Quality Protection
    Permit would no longer be sufficient for the operation of the
    AWRF,” and that, consequently, the City was “[c]learly . . .
    aware at the time it entered into the Agreement that there
    existed some level of fluoride concentration that would
    require treatment prior to its ultimate discharge,” but had
    “inaccurately estimated the particular fluoride concentration
    above which treatment (or pretreatment) [would be]
    required.” The City’s ability to anticipate stricter discharge
    limitations like those ADEQ ultimately passed defeats any
    impossibility defense the City might have asserted, because
    it means the “non-occurrence” of such regulatory change was
    not a “basic assumption on which the contract was made.”

    either because the promisor assumed the risk or for other
    reasons”).

    The City’s most basic counterargument is that the
    Ordinance is an “environmental regulation” of the sort Pure
    Wafer expressly agreed to obey, in section 9.1 of the
    Agreement. “No further analysis is required,” says the City.
    We are not persuaded.
    The trouble with the City’s argument is it completely
    ignores the context of the parties’ negotiations. As the
    district court put it, “Pure Wafer would not construct the
    Prescott facility without a commitment from the City that it
    could discharge up to 100 mg/L of fluoride,” for it “did not
    want to build a Prescott facility that could be ‘rendered
    useless at any time by the City.’” Much like the financial
    institutions in Winstar, “[i]t would . . . have been madness for
    [Pure Wafer] to have engaged in these transactions with no
    more protection than the Government’s reading would have
    given them, for the very existence of their institutions would
    then have been in jeopardy from the moment their agreements
    were 
    signed.” 518 U.S. at 910
    (plurality opinion).
    PURE WAFER V. CITY OF PRESCOTT                 31
    The district court concluded that “[a]ccording to the
    City’s logic, this violation of the Agreement is not a breach
    of contract because Pure Wafer agreed not to discharge
    effluent in violation of local environmental regulations. But
    Pure Wafer neither anticipated nor agreed that it would
    comply with cost-shifting regulations cloaked as
    environmental regulations.” For the reasons explained above,
    we agree with the district court that Pure Wafer was not so
    reckless with its own future, and so we cannot accept the
    City’s position that by agreeing to section 9.1, Pure Wafer
    unwittingly welcomed a Trojan Horse containing within itself
    the seeds of destruction of its own business.
    The City also derives no help from the “reserved powers
    doctrine,” which holds generally that “the exercise of the
    police power cannot be limited by contract for reasons of
    public policy; nor can it be destroyed by compromise,” for “it
    is beyond the authority of the state or the municipality to
    abrogate this power so necessary to the public safety.” N.
    Pac. Ry. Co. v. Minnesota, 
    208 U.S. 583
    , 598 (1908). Pure
    Wafer is not arguing that the City promised never to adopt
    regulations limiting the amount of fluoride industrial users
    like itself may discharge into the City’s sewer system. And
    giving Pure Wafer a contractual remedy for the City’s breach
    would not block the City from reducing the amount of
    fluoride exiting the City’s AWRF. As the City itself
    recognizes, “ultimately the only question is who should pay
    the cost of bringing the Facility into compliance with the
    amended City Code.” Indeed, the district court found that “if
    Pure Wafer does not pretreat its effluent, the City will do so
    to comply with its APP. Counsel for the City has suggested
    as much to the Court.” The City would not be forced to
    surrender any of its sovereign powers if it is held to its
    promise to bear the risk that a change in applicable laws
    32             PURE WAFER V. CITY OF PRESCOTT
    might make performance under the Development Agreement
    more costly.
    E
    In light of the foregoing, we conclude that while the City
    prevails on its appeal of the Contract Clause issue, judgment
    for Pure Wafer can be sustained on the alternative ground that
    the City has breached its contract with Pure Wafer. We leave
    it for the district court on remand to decide the appropriate
    remedy.14
    IV
    The judgment of the district court is AFFIRMED IN
    PART and REVERSED IN PART, and the case is
    REMANDED for further proceedings consistent with this
    opinion.    The district court’s injunction forbidding
    enforcement of the Ordinance against Pure Wafer shall
    remain in effect during subsequent stages in this litigation.
    Each party shall bear its own costs on appeal.
    14
    Because we affirm the district court’s judgment as to the City’s
    liability, we also AFFIRM its denial of the City’s counterclaim. We have
    no occasion to examine the City’s objection to the district court’s separate
    judgment that Pure Wafer is entitled to attorneys’ fees.
    In addition, Pure Wafer’s two motions for judicial notice, filed April
    12, 2016, and April 13, 2016, are GRANTED.
    PURE WAFER V. CITY OF PRESCOTT                       33
    N.R. SMITH, concurring in part and dissenting in part:
    I. United States and Arizona Constitutional Contract
    Clause Claims
    I concur with the majority’s conclusion that “Pure Wafer
    does not have a claim under the Contract Clause” of the
    United States or Arizona Constitutions. Maj. Op. 22. Thus, I
    agree that the judgment must be reversed and remanded.1
    II. Arizona Breach of Contract Claims
    However, I must dissent from the majority’s sua sponte
    decision to reach Pure Wafer’s alternative claims that the City
    breached the Development Agreement. Instead, we should
    remand for the district court (1) to consider whether to
    exercise supplemental jurisdiction over the breach of contract
    claims, and (2) (if it decides to exercise such jurisdiction) to
    make findings of fact as to those claims.
    A. We must allow the district court to assess in the first
    instance whether to exercise its supplemental
    jurisdiction.
    In holding the Contract Clause inapplicable to this case,
    we have dismissed the only federal claim before us. Thus,
    only claims for breach of contract under Arizona state law
    remain. Pure Wafer invoked supplemental jurisdiction over
    these claims in the district court but did not plead diversity.
    Therefore, the first question must be whether the federal,

    I also agree that the City should continue to be enjoined from
    enforcing the Ordinance against Pure Wafer during subsequent stages of
    this litigation.
    34           PURE WAFER V. CITY OF PRESCOTT
    rather than the Arizona state, court should decide the
    remaining claims. See Carnegie-Mellon Univ. v. Cohill,
    
    484 U.S. 343
    , 350 n.7 (1988). The majority errs in failing to
    allow the district court to consider in the first instance
    whether to exercise its supplemental jurisdiction.
    Although district courts generally have supplemental
    jurisdiction over state law claims forming “part of the same
    case or controversy” as federal claims, there are a number of
    circumstances in which “[t]he district court may decline to
    exercise [this] jurisdiction,” including when all federal claims
    have been dismissed. See 28 U.S.C. § 1367(a), (c). The
    decision is discretionary, and, if one of the § 1367(c)
    circumstances is present, “the exercise of discretion [is]
    triggered.” Exec. Software N. Am., Inc. v. U.S. Dist. Court for
    Cent. Dist. of Cal., 
    24 F.3d 1545

    overruled on other grounds by Cal. Dep’t of Water Res. v.
    Powerex Corp., 
    533 F.3d 1087
    (9th Cir. 2008). Section 1367
    plainly vests this discretion with the district court. See
    28 U.S.C. § 1367(c); see also Foster v. Wilson, 
    504 F.3d 1046
    , 1051 (9th Cir. 2007) (“The decision whether to

    Once it dismisses all federal claims before it, a federal
    court “must reassess its jurisdiction by engaging in a
    pragmatic and case-specific evaluation of the myriad of
    considerations that may bear on the determination of whether
    to exercise supplemental jurisdiction.” 16 James WM. Moore
    et al., Moore’s Federal Practice § 106.66[1] (3d ed. 2016).
    Such considerations include “economy, convenience,
    fairness, and comity.” Exec. 
    Software, 24 F.3d at 1557
    (quoting 
    Imagineering, 976 F.2d at 1309
    ). These factors must
    be “weigh[ed] in each case, and at every stage of the
    litigation,” City of Chi. v. Int’l Coll. of Surgeons, 
    522 U.S. 156
    , 173 (1997) (quoting 
    Carnegie–Mellon, 484 U.S. at 350
    ),
    and the district court is in the best position to weigh them, see
    Hoeck v. City of Portland, 
    57 F.3d 781
    , 785–86 (9th Cir.
    1995); 16 Moore, supra § 106.66[3][a]. In my view, an
    Arizona court would be better suited to adjudicate Pure
    Wafer’s claims based on Arizona law. However, the district
    court should make that decision.
    Because the discretion lies with the district court and it is
    in the best position to make the decision, several of this
    court’s opinions indicate that we should allow the district
    court the first opportunity to consider the issue. See Watison
    v. Carter, 
    668 F.3d 1108
    , 1117 (9th Cir. 2012) (“On remand
    [after appellate ruling negated the district court’s basis for
    dismissing state law claims], the district court . . . shall decide
    anew whether to exercise supplemental jurisdiction.”);
    Mendoza v. Zirkle Fruit Co., 
    301 F.3d 1163
    , 1174–75 (9th
    Cir. 2002) (“The decision to exercise [supplemental]
    jurisdiction remains discretionary with the district court. . . .
    We therefore remand for the district court to determine, in the
    first instance, whether the application of the Gibbs standard
    permits the exercise of supplemental jurisdiction, and to
    exercise discretion over whether such jurisdiction would be
    36             PURE WAFER V. CITY OF PRESCOTT
    appropriate in the context of this litigation.”); Webster v.
    Omnitrition Int’l, Inc., 
    79 F.3d 776
    , 790 (9th Cir. 1996) (“The
    Attorney Defendants ask us to dismiss the state law claims
    against them for lack of pendent jurisdiction. The district

    not examine the necessary factors in the first instance.”
    (emphasis added)).
    In Fang v. United States, the plaintiff filed federal and
    state law claims against the United States based on her
    daughter’s death in a national park. 
    140 F.3d 1238
    , 1240 (9th
    Cir. 1998). The district court granted summary judgment on
    the federal claims for lack of subject matter jurisdiction under
    the Federal Tort Claims Act. 
    Id. It also
    dismissed the state
    law claims for lack of subject matter jurisdiction under
    28 U.S.C. § 1367(c)(3). 
    Id. On appeal,
    after deciding to
    reverse the district court’s dismissal of the federal claims, we
    considered the dismissal of the supplemental claims. 
    Id. at 1241–43.
    We reasoned that, because the federal claims “were
    erroneously dismissed, the reason for dismissing the
    remaining supplemental claims no longer exist[ed].” 
    Id. at 1244.
    Declining to rule on the defendants’ arguments that
    complex state law questions and predominance of state law
    issues called for us to uphold the dismissal of the state law
    claims, we held:
    The decision to exercise supplemental
    jurisdiction is within the discretion of the
    2
    Webster cites 28 U.S.C. § 1366, concerning “laws applicable
    exclusively to the District of Columbia,” which were not at issue in that
    case. The citation to § 1366 is clearly a typographical error that was
    intended to cite 28 U.S.C. § 1367.
    PURE WAFER V. CITY OF PRESCOTT                  37
    district court and that court must be given an
    opportunity to make that decision. We
    therefore remand the case to the district court
    where it can determine whether it should
    retain jurisdiction over the state law claims in
    light of [these] alternate arguments.
    
    Id. In Hunsaker
    v. Contra Costa County, the plaintiff brought
    disparate impact disability claims under both federal and state
    law, seeking a permanent injunction. 
    149 F.3d 1041
    , 1042
    (9th Cir. 1998). The district court ordered the injunction on
    the federal claim. 
    Id. This court
    reversed, holding that there
    was no violation of the federal law. 
    Id. at 1044.
    Over the
    plaintiff’s argument that we should, nonetheless, uphold the
    injunction under the alternative state law claim, we held,
    “[t]he district court did not rule on this claim, and we have
    nothing to review. We should allow the district court to
    consider this claim in the first instance or, in its discretion,
    decline to exercise supplemental jurisdiction.” 
    Id. Here, the
    district court initially exercised supplemental
    jurisdiction over the state law breach claims but ultimately
    dismissed them as moot, based on its ruling on the
    constitutional claims. As in Fang, our disposition of the
    federal claims on appeal negated the basis on which the
    district court dismissed the state law claims. In Fang, we
    could have ruled on whether the plaintiff’s claims presented
    novel state law issues that substantially predominated over
    the federal claims, which could have disposed of the state
    claims. However—recognizing (1) that deciding whether to
    exercise supplemental jurisdiction is a discretionary question
    for the district court, and (2) ruling on the defendants’
    38           PURE WAFER V. CITY OF PRESCOTT
    alternative arguments would have deprived the district court
    the opportunity to decide in the first instance whether to
    exercise that jurisdiction—we remanded so the court in the
    best position to rule on the jurisdiction issue could do so. See
    
    Fang, 140 F.3d at 1244
    . The present case compels the same
    result. As in Hunsaker, the district court did not rule on the
    alternative state law basis for the 
    judgment. 149 F.3d at 1044
    .
    Therefore, we have nothing to review with respect to that
    alternative basis, and “[w]e should allow the district court to
    consider [the breach of contract claims] in the first instance
    or, in its discretion, decline to exercise supplemental
    jurisdiction.” See 
    id. B. Because
    the district court held that the breach claims
    were moot, it made no factual findings specific to
    those claims, and we err in failing to remand for
    factual findings now that the claims are no longer
    moot.
    Even if we knew the district court would decide to
    exercise supplemental jurisdiction, remand would still be
    necessary, because the district court made no factual findings
    with respect to the breach of contract claims.
    Although pure interpretation of language in a contract is
    a question of law, see Grosvenor Holdings, L.C. v. Figueroa,
    
    218 P.3d 1045
    , 1050 (Ariz. Ct. App. 2009), the primary
    purpose of contract law in Arizona is to determine the parties’
    intended meaning of the contract at the time of formation, see
    Taylor v. State Farm Mut. Auto. Ins. Co., 
    854 P.2d 1134
    ,
    1138–40 (Ariz. 1993) (in banc), which “is a question of fact
    left to the fact finder,” Chopin v. Chopin, 
    232 P.3d 99
    , 102
    (Ariz. Ct. App. 2010). In cases where extrinsic evidence is
    used to determine the parties’ intent from multiple reasonable
    PURE WAFER V. CITY OF PRESCOTT                  39
    interpretations of contractual language, the interpretation of
    the contract will generally also become a question of fact. See
    In re Estate of Pouser, 
    975 P.2d 704
    , 709 (Ariz. 1999);
    
    Taylor, 854 P.2d at 1144
    –45. Likewise, “[w]hether a party
    has breached [the] contract is a question of fact.” Great W.
    Bank v. LJC Dev., LLC, 
    362 P.3d 1037
    , 1045 (Ariz. Ct. App.
    2015). We must allow the district court an opportunity, in the
    first instance, to make these factual determinations for Pure
    Wafer’s breach of contract claims.
    In its order, the district court found the breach claims
    moot in light of how it disposed of the constitutional claims.
    This treatment of the breach claims resulted in the court
    devoting only about one-quarter of a page (out of a thirty-two
    page opinion) directly to these alternative claims. And even
    that minimal space includes no findings of fact specific to the
    breach claims, instead providing that the district court “need
    not reach Pure Wafer’s alternative [contract] claims.”
    Because the district court found the breach claims moot based
    on the premise that the constitutional claims were valid, our
    ruling today has removed the only basis on which the district
    court dismissed those claims. Therefore, the breach claims
    must be revived. See 
    Fang, 140 F.3d at 1243
    –44 (reinstating
    state law claims where, after court of appeals’ ruling, district
    court’s “reason for dismissing the remaining supplemental
    claims no longer exist[ed]”). Although the breach claims are
    revived—because (1) we have negated the only conclusion
    the district court reached with respect to these claims, and
    (2) the district court made no factual findings specific to the
    breach claims—there is nothing for this court to review
    concerning the claims at this stage. Instead, by deciding the
    breach claims, the majority steps into the role of fact-finder,
    see United Cal. Bank v. Prudential Ins. Co. of Am., 
    681 P.2d 390
    , 454 (Ariz. Ct. App. 1983) (resolving evidentiary
    40           PURE WAFER V. CITY OF PRESCOTT
    questions is the role of the district court), without the benefit
    of district court findings concerning these claims, and relying
    only on findings the district court made in the context of
    constitutional claims that we hold today to be invalid.
    C. The majority decides this case based on the breach of
    contract claims it believes Pure Wafer should have
    alleged, instead of addressing the claims Pure Wafer
    actually alleged.
    In addition to assuming the district court’s role of fact-
    finder, the majority’s breach of contract analysis fails to even
    mention the only two provisions Pure Wafer actually alleged
    in its complaint that the City breached. The complaint alleged
    the City breached the Agreement (1) under section 14.14 by
    failing to exempt Pure Wafer from the 2013 ordinance, and
    (2) under section 9.2 by failing to exempt Pure Wafer from
    the 2013 ordinance. According to the majority, Pure Wafer
    alleged “that the City, by enacting the Ordinance, had
    committed at least two different breaches of contract.” Maj.
    Op. 12–13. Although this initial statement about the breach
    claims is accurate, when the majority actually discusses the
    substance of those claims it does not once cite to, or analyze
    the content of, section 14.14 or section 9.2 of the Agreement.
    The majority also asserts that “Pure Wafer included a claim
    for simple breach of contract in its suit against the City,
    alleging that ‘Pure Wafer cannot comply with the Ordinance
    without incurring substantial costs which the Development
    Agreement allocated to the City.’” 
    Id. at 19–20.
    While, again,
    the majority correctly recognizes that Pure Wafer included
    breach of contract claims, it implies, incorrectly, that Pure
    Wafer alleged facts concerning cost allocation specifically in
    the context of its breach claims. Pure Wafer did not. Instead
    of considering the breach claims as Pure Wafer alleged them,
    PURE WAFER V. CITY OF PRESCOTT                  41
    the majority analyzes the breach claims it believes Pure
    Wafer should have alleged, rules in Pure Wafer’s favor on
    those claims, and never addresses the breach claims Pure
    Wafer actually alleged in its complaint.
    D. The majority’s analysis of the breach claims
    contradicts a plain reading of the Agreement, fails to
    address several relevant provisions, and demonstrates
    that further factual development may be needed.
    As noted, the primary goal of Arizona contract law is to
    determine the parties’ intended meaning of their agreement
    and to give effect to that contractual intent. See 
    Taylor, 854 P.2d at 1138
    –40. Thus, in attempting to discover the
    parties’ intent, courts are to liberally consider extrinsic
    evidence to show the parties’ intended interpretation of their
    contractual language. See 
    id. at 1138–41.
    However, because
    “[i]nterpretation is the process by which we determine the
    meaning of words,” see 
    id. at 1138,
    extrinsic evidence is
    useful only to the extent it reveals how the parties’ intent is
    reflected in the words they chose to memorialize their
    agreement, see 
    id. at 1140–44;
    see also Smith v. Melson, Inc.,
    
    659 P.2d 1264
    , 1266 (Ariz. 1983) (in banc) (“A contract
    should be read in light of the parties’ intentions as reflected
    by their language and in view of all the circumstances.”). And
    the further an interpretation gets from the contract’s actual
    language, the more convincing the extrinsic evidence must be
    to show the parties intended that meaning. See 
    Taylor, 854 P.2d at 1139
    –40. In addition, the parties’ intent for
    specific contractual language must be determined in light of
    their entire agreement. See 
    Smith, 659 P.2d at 1267
    .
    At the heart of the parties’ dispute are two difficult,
    interrelated issues: (1) the limits of Pure Wafer’s right to
    42           PURE WAFER V. CITY OF PRESCOTT
    discharge into the City’s sewer, and (2) who bears the cost of
    bringing that discharge into compliance with Arizona
    Department of Environmental Quality (ADEQ) requirements.
    The majority appears to rely exclusively on section 4.2 of the
    Agreement to answer these questions. Although its
    interpretation could be valid, it fails to analyze the specific
    language of the provision on which it relies. Further, the
    majority fails to consider several other provisions implicated
    here. When read as a whole, the Agreement is clearly
    susceptible to multiple reasonable interpretations with respect
    to these issues.
    1. The majority’s interpretation of Pure Wafer’s
    discharge rights contradicts section 4.2’s plain
    meaning and has insufficient supporting extrinsic
    evidence to overcome that contradiction.
    The parties dispute what limits the Agreement places on
    Pure Wafer’s right to discharge, and the City’s obligation to
    accept, wastewater into the City’s sewer system. Section 4.2
    requires the City to provide Pure Wafer 195,000 gallons of
    daily “sewer capacity.” It further provides that the “City shall
    not reclassify [Pure Wafer’s] effluent” for purposes of sewer
    usage rates “unless there is a material change in the waste
    water quality from the specifications attached hereto as
    Exhibit F.” Exhibit F, in turn, lists 50 mg/L as the “typical
    value” for fluoride and 100 mg/L as the “maximum.”
    Contrary to the findings of the district court, the majority
    concludes Pure Wafer only has a right to discharge
    wastewater of up to 100 mg/L fluoride. See Maj. Op. 8, 28,
    30. The majority relies on Exhibit F for this limit. See 
    id. at 8–9.
    It also relies on certain extrinsic evidence: (1) testimony
    that, at the time of the Agreement, Pure Wafer expected to
    PURE WAFER V. CITY OF PRESCOTT                  43
    discharge up to 100 mg/L fluoride and this understanding was
    critical to its negotiations, 
    id. at 28;
    (2) a 2004 letter
    indicating that a City employee understood Pure Wafer to
    have such a right, 
    id. at 29;
    and (3) letters from ADEQ to the
    City prior to the Agreement reflecting that the City knew it
    must obtain an aquifer protection permit, see 
    id. at 29.
    The district court below persuasively analyzed, and found
    antithetical to the Agreement’s plain meaning, the conclusion
    the majority now reaches as to Pure Wafer’s discharge rights.
    Though section 4.2 obligates the City to supply sewer
    capacity, it does not provide that Pure Wafer has a right to
    discharge wastewater (through that capacity) with any
    specified level of pollutants, or that there are any limits
    (regardless of fluoride content) on what Pure Wafer may send
    through its 195,000 daily gallons of sewer capacity.
    Exhibit F’s plain language cannot be read to impose
    discharge limits, as the majority asserts. The district court
    persuasively rejected the argument that Exhibit F established
    any measure of Pure Wafer’s right to discharge effluent of a
    particular fluoride content, and instead, held that no contract
    provision could reasonably be interpreted to set such a limit.
    The Agreement refers to Exhibit F only once. A plain reading
    of that reference shows Exhibit F does not create any right to
    discharge a certain amount of fluoride, but rather, relates only
    to “sewer usage fees” Pure Wafer must pay for “sewer
    capacity” under section 4.2. This reading was confirmed by
    Pure Wafer’s only trial witness, who was involved in the
    original planning of the Prescott facility. He testified that
    Exhibit F did not relate to any right for Pure Wafer to
    discharge certain contaminant levels but, instead, related only
    to pricing.
    44           PURE WAFER V. CITY OF PRESCOTT
    Although the majority points to extrinsic evidence to
    support its position, it fails to address the interpretation
    problem pointed out by the district court—that there is no
    provision in the Agreement, the words of which we could
    reasonably interpret to impose a 100 mg/L limit. There is no
    better indication of contractual intent than a plain reading of
    the language the parties chose to express their rights and
    obligations in the Agreement. And, here, that language does
    not support the majority’s position. Extrinsic evidence is
    persuasive only to the extent that it shows the parties’ intent
    through the meaning of the contractual language, see 
    Taylor, 854 P.2d at 1140
    –44; 
    Smith, 659 P.2d at 1266
    , and the further
    an interpretation varies from the written language, the more
    convincing the evidence must be to show the parties intended
    the proffered interpretation, see 
    Taylor, 854 P.2d at 1139
    –40.
    The evidence on which the majority relies does not clear this
    bar. Neither does the majority address the testimony of Pure
    Wafer’s only witness, which contradicts the majority’s
    reading of Exhibit F. Based on the conflicting interpretations
    of the parties’ intended rights and obligations concerning
    discharge, at the very least, the district court should be
    permitted to determine the facts in the context of Pure
    Wafer’s breach of contract claims. And, if on remand, there
    is not persuasive evidence as to the parties’ actual intent, any
    remaining ambiguity in the parties’ rights and obligations
    should be interpreted against Pure Wafer as the party who
    drafted the agreement. See Polk v. Koerner, 
    533 P.2d 660
    ,
    662 (Ariz. 1975). Interpretation against the drafter is
    particularly applicable where the “party is attempting to
    impose an obligation on another where otherwise such an
    obligation would not exist.” United Cal.

    .
    PURE WAFER V. CITY OF PRESCOTT                     45
    2. The majority’s interpretation of the Agreement’s
    cost allocations contradicts the plain meaning of
    section 4.2 and ignores several provisions
    relevant to the financial obligations.
    The parties’ discharge rights and obligations also relate to
    a second question at issue here: When environmental laws
    allow the City to release wastewater into the aquifer only if
    its fluoride content is below a certain level, and it is
    undisputed that Pure Wafer’s discharge causes excess
    fluoride levels, who bears the cost of abatement? The
    majority interprets section 4.2 to impose the cost on the City.
    See Maj. Op. 7–8, 24–29. It posits that, by agreeing to take
    Pure Wafer’s discharge, the City agreed to bear the cost if the
    law required purification to reduce the fluoride. However, this
    reading contradicts section 4.2’s plain meaning and fails to
    consider several other provisions that appear to affect the
    parties’ financial obligations.
    Section 4.2 expresses when and how (logistically) the
    City provides “sewer capacity” to Pure Wafer: It must hold
    195,000 gallons of physical carrying capacity in “reserve in
    its sewer disposal system at all times after commencement of
    construction of the Facility.” Section 4.2 refers to existing
    “[t]runk line facilities . . . currently in place [that] appear[ed]
    adequate” to provide this carrying capacity. However, if the
    trunk line facilities “prove[d] inadequate,” the “City [was]
    obligated to augment such facilities . . . by constructing at no
    cost to [Pure Wafer] all mains, lines, and other facilities
    necessary to accept or accommodate the additional sewer
    flow or effluent from the facility.”
    The majority suggests the City’s obligation to “augment
    [inadequate] facilities” amounts to a “regulatory contract”
    46          PURE WAFER V. CITY OF PRESCOTT
    under which the City guaranteed Pure Wafer the benefit of
    the regulatory scheme existing at the time of the Agreement
    by agreeing to bear the cost of any changes. Maj. Op. 7–8,
    24–29. However, a plain reading of section 4.2 requires only
    that the City make available a specified amount of physical
    space in the sewer system to accommodate Pure Wafer’s
    discharge. And, if the sewer lines existing at the time of the
    Agreement turned out to be insufficient to handle the required
    volume of discharge, section 4.2 placed the financial burden
    on the City to augment only the physical capacity of those
    lines to accommodate the additional discharge that could not
    otherwise physically fit through the system. See United Cal.
    
    Bank, 681 P.2d at 425
    (explaining that where a contract
    includes general terms that accompany specific terms
    covering the same subject matter, “the meaning of the general
    terms is presumed to be limited [by] the enumerated specific
    terms and to include only those things of the same nature as
    those specifically enumerated”).
    The majority again fails to explain how the language of
    section 4.2 supports its position. The section does not impose
    an obligation to build some extensive purification facility,
    unrelated to the sewer’s physical capacity to accept a certain
    volume of wastewater through its pipes. Some extrinsic
    evidence may support the majority’s position, but again, that
    evidence is persuasive only to the extent it can be tied back
    into the actual language of the Agreement, see 
    Taylor, 854 P.2d at 1140
    –44; 
    Smith, 659 P.2d at 1266
    , which the
    majority has failed to do. Instead, a plain reading of section
    4.2 supports a more reasonable alternative. Given the
    conflicting interpretations, the district court should be given
    the opportunity to make findings of fact—in the context of
    Pure Wafer’s breach of contract claims—as to the parties’
    understandings of the language in section 4.2. And if, at that
    PURE WAFER V. CITY OF PRESCOTT                   47
    point, ambiguity remains as to their intended meaning, that
    ambiguity should be resolved against Pure Wafer as the
    drafting party. See 
    Polk, 533 P.2d at 662
    ; United Cal. 
    Bank, 681 P.2d at 412
    .
    In addition to section 4.2’s plain meaning, several other
    provisions may bear on the parties’ financial obligations
    under the contract. Yet the majority has limited its analysis to
    section 4.2 in isolation. See 
    Smith, 659 P.2d at 1267
    . Read as
    a whole, article 4 of the Agreement may also speak to the
    parties’ cost allocations. For example, the detail with which
    they allocate risk in section 4.3 tends to negate an
    interpretation that section 4.2 makes allocations not explicitly
    stated. Under circumstances not present here, section 4.3
    expressly places on Pure Wafer:
    responsib[ility] for any engineering and
    construction associated with the connection to
    that infrastructure[, which shall] include, but
    not be limited to, metering and sampling
    devices and structures, pipeline, pump
    stations, etc. . . . [Pure Wafer] shall be
    responsible for sampling and testing costs. . . .
    In the event that [Pure Wafer] discharges
    effluent of an inferior quality than is required
    by permit, and the City’s facilities are
    negatively impacted, [Pure Wafer] shall be
    financially responsible.
    Because some sections allocate the responsibilities, risks, and
    costs in such detail, it is reasonable to assume that the parties
    would have made similar explicit allocations in section 4.2,
    if they intended section 4.2 to have that effect.
    48          PURE WAFER V. CITY OF PRESCOTT
    The Agreement may also allow “surcharges” to Pure
    Wafer if its fluoride levels increase the City’s processing
    costs. Section 4.1, “Operations Water Supply,” provides that
    “Water Supply shall be at City’s sole expense, without any
    special assessments, costs, [or] surcharges.” Section 4.2
    contains no protection against surcharges. Further, Pure
    Wafer’s only witness testified that section 4.2 and Exhibit F
    allow the City to charge higher sewer rates as discharge
    contaminants increase “because it will cost [the City] more to
    process.” His testimony indicates the parties may have
    understood, upon executing the Agreement, that if the quality
    of Pure Wafer’s discharge increased the City’s processing
    costs, the increased costs could be passed on to Pure Wafer.
    While section 4.2 provides cost protections to Pure Wafer,
    these protections may not prohibit increased processing costs.
    Section 4.2 prohibits increasing Pure Wafer’s “sewer usage
    fees” absent “a material change in the waste water quality.”
    It also provides, “Sewer Capacity shall be at no cost” to Pure
    Wafer other than “normal sewer usage fees.” As noted,
    section 4.2 indicates “sewer capacity” refers only to physical
    sewer space to carry away discharge. Therefore, it would not
    preclude discharge-related charges for something other than
    that physical space, such as a surcharge for the City’s extra
    costs of processing the excess fluoride. Such a “surcharge”
    would not amount to a “normal sewer usage fee” protected
    under section 4.2, nor would it be assessed for “sewer
    capacity.”
    In addition, evidence of the parties’ dealings as to the
    excess-fluoride costs may show their understandings of cost
    allocations. See United Cal. 
    Bank, 681 P.2d at 418
    (explaining that the parties’ treatment of terms after the
    contract is executed but before a dispute as to meaning arises
    PURE WAFER V. CITY OF PRESCOTT                   49
    “is entitled to great weight” as evidence of the parties’
    intended meaning for those terms). During the period of their
    Agreement, the City accepted Pure Wafer’s discharge
    regardless of quality. However, whenever ADEQ found the
    City in violation of fluoride limits, the City demanded Pure
    Wafer’s help to remedy the problem. And the record reflects
    Pure Wafer did help. Although some evidence suggests Pure
    Wafer provided the assistance despite having no obligation to
    do so, other evidence suggests Pure Wafer believed it was
    obligated to help bear these costs: A 2004 letter from Pure
    Wafer to the City (following the City’s Notice of Violation
    (NOV) from ADEQ) outlined, “It is [Pure Wafer’s] intent to
    work with the City to assure that its discharge . . . will enable
    the City to consistently meet all of its permit requirements,
    including fluoride.” The letter also explained Pure Wafer’s
    plan to reduce fluoride concentrations. Finally, the letter
    provided that “the NOV issued to the City is directly related
    to our operations and potential remedial solutions may
    require expenditures on our part.” Other 2004 letters indicate
    that Pure Wafer hired an environmental engineer to determine
    how to reduce fluoride levels. Pure Wafer’s reduction of
    fluoride when its discharge caused the City to exceed
    permitted levels tends to contradict Pure Wafer’s position that
    it had a right to discharge wastewater with any fluoride
    content. Given these interpretation problems, the district court
    should have the first chance to determine the facts as to all of
    the matters that may have affected the parties’ understandings
    of their cost allocations.
    A final contract provision that may bear on the parties’
    financial obligations is section 12, “Force Majeure.” Both
    parties claim it would cost several million dollars to achieve
    compliant fluoride levels. Given this burden, both parties
    might claim defenses under section 12, which protects a party
    50           PURE WAFER V. CITY OF PRESCOTT
    from defaulting where “inability to perform [is] due [to] . . .
    acts or the failure to act, of any utility, public or
    governmental agent or entity . . . beyond the control or
    without the fault of such party.” Changes to environmental
    laws imposing new burdens on either party could possibly
    amount to governmental action beyond the control and
    without the fault of the parties. But the district court should
    be given the first opportunity to make factual determinations
    as to the parties’ understandings of the scope of this
    provision.
    In sum, the majority errs in failing to consider (in any
    manner) many of the provisions that may bear on the issues
    before us and in failing to recognize that the provisions on
    which it relies are subject to competing interpretations by
    Pure Wafer and the City. We should allow the district court
    to make the factual determinations with respect to these
    issues in the first instance.
    E. Without allowing the district court an opportunity to
    consider the question, the majority bases its decision
    on a record that may be insufficient to show the
    parties’ contractual intent.
    In addition to the lack of written findings as to the breach
    claims, a review of the present record suggests that the
    abbreviated proceedings in the district court may not have
    allowed for admission of extrinsic evidence sufficient to show
    the parties’ contractual intent. The district court should be
    permitted on remand to determine whether, under Arizona
    contract law, the record is adequately developed with facts
    that show what the parties truly intended their agreement to
    mean.
    PURE WAFER V. CITY OF PRESCOTT                   51
    1. Lack of attention to the breach claims indicates
    that the parties have not adequately developed the
    record as to those claims.
    The history of this case evidences that the proceedings
    may not have sufficiently developed the record on the breach
    claims to allow a proper ruling on the merits. The parties
    conveyed their initial expectations for the timing of all the
    claims in this case in their joint December 2013 planning
    report, where they estimated that discovery would take until
    the end of April 2014 and the case would be ready for a three-
    or four-day trial at the end of May. Instead of progressing
    pursuant to this expected timeline, the evidentiary
    proceedings in the district court were completed within five
    weeks of the parties filing their initial planning report and
    concentrated almost exclusively on the constitutional claims.
    Pure Wafer did not include breach of contract claims in its
    initial complaint. Although Pure Wafer later amended to add
    the breach claims at issue, it then immediately moved for a
    preliminary injunction, making no argument that its breach
    claims justified an injunction or that the claims would
    eventually succeed on the merits. Instead, its motion sought
    an injunction “pending a final judgment determining Pure
    Wafer’s constitutional claims.” The motion referred to the
    breach claims only once, representing that Pure Wafer
    “add[ed] purely alternative claims for breach of contract . . .
    and breach of the implied covenant of good faith and fair
    dealing . . . [and that g]iven the City’s stated positions, those
    claims would not succeed and [were] asserted only in the
    alternative . . . out of an abundance of caution.” It was with
    this perspective toward the breach claims that the parties and
    district court would have prepared for the preliminary
    52           PURE WAFER V. CITY OF PRESCOTT
    injunction hearing, which the court scheduled for December
    19, 2013.
    The district court limited each party to only three and one-
    half hours to present evidence and argument. Thus, Pure
    Wafer called only one witness during its presentation-in-
    chief. At the close of the first day (during which the City also
    called only one witness), the district court suggested they
    proceed immediately with a trial on the merits, consolidate it
    with evidence heard on the motion for preliminary injunction,
    and finish presenting the evidence on the next available court
    date (January 14, 2014). The parties agreed to the district
    court’s suggestion. The court’s subsequent order provided
    that the remainder of trial would be limited to the City calling
    one more defense witness and Pure Wafer calling one rebuttal
    witness (the same witness it called in its direct presentation).
    The order also provided in a footnote that “the trial
    necessarily includes the issue of liability on any claims
    pleaded in the alternative, namely Pure Wafer’s alternative
    claims for breach of contract and breach of the implied
    covenant of good faith.” In other words, trial of the
    alternative claims was ordered only after Pure Wafer
    completed its presentation-in-chief, which focused primarily
    on the preliminary injunction on the constitutional issues.
    Indeed, when both parties would have been planning which
    witnesses to subpoena, which to call, what questions to ask,
    and what other evidence to present, they would have made
    those decisions understanding that their presentations needed
    to pertain only to Pure Wafer’s entitlement to a preliminary
    injunction based exclusively on its constitutional claims. And
    they certainly would not have made these decisions with the
    understanding that they needed to try their entire cases, which
    they had estimated (in their initial planning report) would not
    be ready for five more months. This approach to the
    PURE WAFER V. CITY OF PRESCOTT                            53
    evidentiary proceedings below highlights why the parties and
    district court did not attempt to develop the record for the
    breach of contract claims.
    Like the evidentiary portion of trial and every prior filing
    in the case, the post-trial briefing and proposed findings and
    conclusions only superficially addressed the breach claims.
    As noted, the district court’s opinion devoted less than one-
    quarter of a page (out of thirty-two pages) to the breach
    claims, holding that they need not be reached and dismissing
    them as moot.
    The parties’ treatment of the breach of contract claims on
    appeal further supports the conclusion that the parties and
    district court did not attempt to develop the record for the
    purpose of addressing those claims. The only reference the
    parties’ briefing made to the claims was in the City’s opening
    brief: “Pure Wafer’s breach of contract claims . . . were
    dismissed as moot and are not at issue on this appeal.” Pure
    Wafer never disputed this position. Indeed, when asked at
    oral argument, neither party was prepared to address the
    appeal as a breach of contract case. We asked the City, “is
    there a reason we can’t treat [this case] as a contract issue?”
    The City answered, “I don’t think the record is developed to
    that—that the findings of fact and conclusions of law are
    developed to that level to permit you to do that.”3
    3
    This questioning occurred during the City’s rebuttal. The panel
    initially raised the issue in its first question during Pure Wafer’s argument,
    only after the City had already completed its argument-in-chief without
    being asked to argue its position on the issue. Because the panel spent the
    majority of Pure Wafer’s argument exploring whether we could approach
    the case as a breach of contract dispute, it is troubling that the panel did
    not raise the issue at a time that would ensure the City an equal
    opportunity to address it.
    54           PURE WAFER V. CITY OF PRESCOTT
    Pure Wafer was equally reluctant to agree that the case
    could appropriately be decided as a breach of contract claim
    on the present record. Even in response to the question, “can
    you still prevail in this particular appeal by persuading us that
    the district court made enough findings to establish that this
    was a breach of contract,” Pure Wafer never adopted that
    position. As its argument came to a close, Pure Wafer
    conceded that the parties’ cost allocations for reducing
    fluoride was a term fully covered by the Agreement.
    Following this concession, however, we clarified whether
    Pure Wafer thought that (because the term was covered by the
    Agreement) the case could be decided on a breach of contract
    theory, rather than by reaching the constitutional issue. Pure
    Wafer reluctantly answered, “Maybe.” This ambivalent
    response (the last word of Pure Wafer’s argument) typifies
    the parties’ and district court’s perspective of the breach
    claims throughout this case.
    2. Having clearly not focused on the breach of
    contract claims, the proceedings up to this point
    may have left the factual record without adequate
    evidence of the parties’ contractual intent.
    In light of Arizona’s goal of giving effect to the parties’
    intent, the Arizona Supreme Court in Taylor explained the
    great extent to which the state allows parties to offer extrinsic
    evidence to show their understandings of contractual
    language, and thus, their contractual intent. 
    See 854 P.2d at 1138
    –41. In analyzing the meaning of language and how it
    shows the parties’ intent, Arizona has expressly rejected the
    requirement “to make a preliminary finding of ambiguity”
    before the court can consider extrinsic evidence. See 
    id. at 1138.
    Instead, the court must consider all extrinsic evidence
    that may support a party’s reasonable interpretation of
    PURE WAFER V. CITY OF PRESCOTT                   55
    contractual language as showing the party’s theory of
    contractual intent. See 
    id. at 1139.
    Under this more liberal
    approach, Arizona allows the court to “consider surrounding
    circumstances, including negotiation, prior understandings,
    . . . subsequent conduct,” and the like in interpreting the
    contract. See 
    id. at 1139–40;
    see also 
    Smith, 659 P.2d at 1267
    (“When interpreting an agreement, the court may always
    consider the surrounding circumstances.” (citing Restatement
    (Second) of Contracts § 212 (1981))). If extrinsic evidence
    shows the parties used language in their contract they
    mutually understood and intended to have a certain meaning,
    the court must give effect to that intent, even if the words
    have a different meaning under ordinary usage. See 
    Taylor, 854 P.2d at 1139
    . “[T]he purpose is to produce the contract
    result the parties intended, not that which the judge intends.
    Some words are clear beyond dispute. Some may mean one
    thing to the judge but could have meant something else to the
    parties. It is the latter meaning that is important.” 
    Id. at 1141
    n.2.
    Because the proceedings in the district court did not
    concentrate on the breach of contract claims, the parties had
    no reason to develop the record with all the facts relevant to
    those claims. Pure Wafer has consistently maintained that the
    parties extensively negotiated before executing the
    Agreement. It alleged that they met “on many occasions and
    communicated . . . by telephone and written
    communications.” It also alleged they “spent several months
    negotiating the terms of [their Agreement] to provide the
    protection desired both to Pure Wafer and to the City, on the
    key economic development elements of their deal.”
    According to Pure Wafer, “effluent capacity and quality were
    material terms the parties considered and negotiated . . . , and
    [the Agreement] reflects those bargains.” It alleged the parties
    56           PURE WAFER V. CITY OF PRESCOTT
    negotiated for the City to accept effluent of a specific
    “chemical profile,” and to accept the risk that the City’s
    permit requirements could change, resulting in extra expense.
    In describing the parties’ negotiations, the district court
    cited only one exhibit and seven pages of trial transcript,
    coming from the testimony of only one witness. And even
    these two items were considered by the district court only for
    their relevance to the constitutional claims. The court did not
    address how this evidence may have pertained to the breach
    of contract allegations, because it found those claims to be
    moot. Arizona law allows a party to offer—and requires the
    court to consider—all extrinsic evidence that supports the
    party’s reasonable interpretation of a contract. Given Pure
    Wafer’s continued insistence that the parties extensively
    negotiated the terms at issue in this case prior to executing the
    Agreement, it is most likely that more extensive and
    compelling evidence exists than the current record shows.
    For example, there is no evidence in the record to
    establish the City’s intended meaning of the Agreement and
    understandings from the negotiations at the time of contract
    formation. Surely someone from the City involved in (or
    knowledgeable on the details of) the many months of
    “telephone and written communications” between the parties
    would be available to provide this information. Concerning
    negotiations, there may be several witnesses who can testify,
    early drafts of the Agreement, the parties’ notes on those
    drafts, communications regarding their understandings of
    certain terms, compromises they reached, terms they changed,
    etc., all of which is highly relevant and necessary to
    determining the parties’ intent, but none of which can be
    found in the record. The record indicates such evidence
    exists; it simply has not been made part of the record. For

    example, a 1997 internal Pure Wafer memo refers to
    discussions of sewer usage rates the parties had at “the
    Development Agreement meeting.” However, the record
    contains no minutes, notes, or correspondence to show
    specifically what was discussed at this meeting. Similarly, a
    2011 letter from Pure Wafer to the City outlined that, in
    preparing the letter, Pure Wafer’s attorney “pulled [Pure
    Wafer’s] file from the time the Agreement was drafted and
    reviewed the notes of [his] meetings and telephone
    conversations with the City, as well as correspondence with
    the City and drafts of the Agreement.” Yet these notes,
    written correspondence, and draft Agreements are absent
    from the record. Given this record, the testimony of a single
    witness (testifying on Pure Wafer’s behalf) does not seem
    sufficient to establish the contractual intent of both parties at
    the time they executed the Agreement, especially where so
    much additional extrinsic evidence is likely available.
    The parties’ true intent cannot be revealed without
    consideration of all available evidence and application of that
    evidence to the language of the contract as a whole. Though
    it is certainly within the fact-finder’s discretion, I anticipate
    the district court on remand would want to conduct additional
    proceedings with respect to the breach claims, because the
    lack of attention to those claims leaves the record far short of
    containing all available evidence of contractual intent. The
    parties should be permitted to develop concrete evidence of
    their positions and understandings of the relevant terms at the
    time they executed the Agreement.
    III.    Conclusion
    The district court should have the first opportunity to
    consider whether to exercise supplemental jurisdiction,
    58           PURE WAFER V. CITY OF PRESCOTT
    because we have dismissed the only federal claim. This
    dismissal also necessitates a remand for the district court to
    make findings of fact and conclusions of law specific to the
    breach of contract claims, having previously found those
    claims to be moot. The majority errs by stepping into the role
    of fact-finder in the first instance with respect to the breach
    claims; by failing to address the claims Pure Wafer actually
    alleged; and by failing to recognize that its analysis of the
    breach claims contradicts the Agreement’s plain meaning,
    fails to consider the Agreement as a whole, and is lacking
    adequate support from the record.
    The circumstances warrant remand to permit the district
    court (or an Arizona court) the first opportunity to address the
    merits. Doing so would allow the trial court to focus on the
    language of the Agreement and, in accordance with Arizona
    law, consider any extrinsic evidence that supports a
    reasonably susceptible interpretation of the contract. While I
    am cognizant of the desire for a speedy and efficient
    resolution of this dispute, the majority’s opinion sacrifices a
    proper and thorough resolution of this case for a speedy one.
