    WATERMAN, Justice.
    An Iowa municipality and a rural water district are litigating
    competing claims in federal court for the right to provide water service to
    disputed areas within two miles of the city limits. The city contends that
    it prevails under the “two-mile rule” codified in Iowa Code section 357A.2
    since 1987. The rural water district contends that it prevails under federal
    statutory protection for rural water service in 
    7 U.S.C. § 1926
    (b), the
    county board resolution defining its territory, an exception to the two-mile
    rule in section 357A.2(4) added by a 2014 amendment the district argues
    applies retroactively, and its alleged “dual status” as a chapter 504A
    nonprofit corporation.
    The federal court certified three questions of Iowa law to our court.
    The city and its amicus curiae urge us to answer each question in the
    negative; the rural water district and its amici curiae urge us to answer
    each question in the affirmative. For the reasons explained in this opinion,
    we answer the certified questions as follows:
    Question 1: Whether an Iowa Code § 357A.2 rural water
    district, before amendments to § 357A.2(4) in 2014, had a
    legal right to provide water service to portions of an area
    described in its count[y] board of supervisors resolution, see
    Iowa Code § 357A.2(1), when those portions were also within
    two miles of the limits of a municipality, see § 357A.2(3), and
    when the municipality had not waived its rights to provide
    water service to the area, see § 357A.2(4).
    Answer: No.
    Question 2: Whether Iowa Code § 357A.2(4), as amended by
    the Iowa legislature in 2014: (a) exempts a rural water district
    from following notice-of-intent procedures when the area the
    district seeks to serve is within the district’s boundaries as
    designated in the county board of supervisors’ resolution
    creating the water district, and/or (b) otherwise provides the
    rural water district a legal right to serve such areas when the
    municipality has not waived its rights. If so, whether the 2014
    amendment to § 357A.2(4) had retroactive effect.
    Answer: No.
    4
    Question 3: Whether an Iowa Code § 504A nonprofit
    corporation created in 1977 had a legal right to provide water
    service anywhere within the state of Iowa. If so, whether a
    § 504A nonprofit corporation that reincorporated (including
    through articles of dissolution for the § 504A entity) as a
    § 357A.2 rural water district in 1990 retained the legal right
    to provide water service anywhere within the state of Iowa
    (including outside its boundaries as specified in its county
    board of supervisors resolution and within two miles of a
    municipality), prior to and following the 1991 amendment to
    § 357A.2.
    Answer: No, and upon reincorporating under chapter 357A, the rural
    water district’s territorial rights are governed by that chapter,
    including its two-mile rule, and any broader territorial rights under
    chapter 504A were abandoned.
    In summary, we construe Iowa Code section 357A.2 since 1987 as
    granting cities the primary right to provide water service in areas within
    two miles of the city limits that were not already being served by a rural
    water district. A rural water district that seeks to extend service to a new
    tract within two miles of the city limits must first request the city’s
    approval. The two-mile rule was enacted to allow cities room to grow and
    also to resolve turf battles like this between cities and rural water districts.
    We harmonize the Iowa statute with federal law, which acts as a shield
    protecting a rural water district’s existing customers, not as a sword to
    strike down the state’s two-mile rule for new infrastructure. The county
    board resolution by its terms is subject to chapter 357A and in any event
    yields to state law. The 2014 amendment to section 357A.2(4) only applies
    when a rural water district adds new customers to or improves existing
    facilities in its existing service area or pursuant to an existing agreement.
    The two-mile rule is not avoided by any “dual status” for a 504A1 nonprofit
    corporation that reorganizes under chapter 357A.
    1In  July 2005, chapter 504A was repealed. See 2004 Iowa Acts ch. 1049, § 190.
    Its provisions merged into the Revised Iowa Nonprofit Corporation Act. See 2004 Iowa
    Acts ch. 1049 (codified at Iowa Code ch. 504 (2005)).

    I. Background Facts and Proceedings.
    “When we answer a certified question, we rely upon the facts
    provided with the certified question.” Baldwin v. City of Estherville, 
    915 N.W.2d 259
    , 261 (Iowa 2018). We summarize those facts as follows.
    The City of Johnston (Johnston) is an Iowa municipality that
    operates its own water supply system. Xenia Rural Water District (Xenia)
    is a rural water provider operating in Polk County, Iowa, among other
    locations. In 1977, Xenia incorporated under Iowa Code chapter 504A as
    a nonprofit corporation entitled “Xenia Rural Water Association.” On May
    18, 1982, Xenia borrowed $3.2 million from the United States Department
    of Agriculture (USDA). On October 30, 1990, Xenia petitioned the Polk
    County Board of Supervisors (PCBOS) to convert to a rural water district
    under Iowa Code chapter 357A; the PCBOS granted its petition in a
    November 27, 1990 resolution, which stated, in part:
    BE IT FURTHER RESOLVED that it is the order of the
    Polk County Board of Supervisors that the district whose
    boundary includes the area in Polk County described as
    follows be and hereby is established as the Xenia Rural Water
    District with all of the rights, powers and duties specified in
    Chapter 357A of the code of Iowa, as amended:
    All of the following sections in Polk County except that
    portion lying within the boundary of any incorporated
    city on the date hereof:
    (1) The North 1/2 of Sections 1, 2, and 3, all of
    Sections 4 through 9, Sections 16 through
    20, and Sections 29, 30, 31, 32, and that
    part of Section 33 west of Saylorville Lake all
    in Township 81 North Range 25 West.
    (2) All of that part of Sections in Township 80
    North Range 25 West lying westerly of
    Saylorville Lake.
    In April of 1991, Xenia’s board signed articles of dissolution for the
    nonprofit entity, which transferred its assets to the chapter 357A entity.
    6
    The articles of dissolution of the 504A entity were filed with the Iowa
    Secretary of State.
    There are two sets of service areas subject to the pending suit, which
    Xenia refers to as the “Encroachment Areas” and the “Disputed Area,” or
    collectively, “the areas in dispute.” The parties agree that the areas in
    dispute are within the boundaries described in the PCBOS resolution.
    Some portions of the areas in dispute are within two miles of Johnston’s
    city limits. According to Johnston, “most of the area within the ‘Disputed
    Area’ remains undeveloped or relies on well water.” The Disputed Area
    contains approximately 1900 acres, including approximately 550 acres
    annexed by Johnston in 2018 and another portion of approximately 1350
    acres that Johnston intends to annex, which it describes as “primarily
    undeveloped rural acreage.”     Johnston has provided water service to
    portions of the Encroachment Areas since at least 1995 and continues to
    do so. Xenia has no pipes in the ground or customers it already serves
    within the areas in dispute.
    In early 2018, Xenia and Johnston began negotiating over which
    entity would provide water services requested by the United States Navy
    for a facility it was building in the Disputed Area. The negotiations led to
    an April 4, 2018 Interim Agreement that stated, in relevant part, “Section
    357A.2 of the [Iowa] Code provides that Xenia may not provide services
    within two miles of the limits of Johnston unless Johnston has approved
    a new water system plan.” The agreement was signed by the Mayor and
    City Clerk of Johnston and the Chair and Secretary of Xenia. The area
    Johnston intended to annex included sections both within and beyond two
    miles from the city limits. In September 2018, negotiations broke down
    after Johnston offered approximately $1.58 million to Xenia for its rights
    to areas over two miles from the city limits.
    7
    On November 3, Xenia filed a three-count Complaint against
    Johnston in the United States District Court for the Southern District of
    Iowa.    On January 4, 2019, Xenia filed a five-count First Amended
    Complaint. Count One alleges that Johnston violated 
    42 U.S.C. § 1983
     by
    depriving Xenia of its rights under 
    7 U.S.C. § 1926
    (b), which protects
    certain entities indebted to the USDA from municipal encroachment.
    Count Two seeks a declaratory judgment as to Xenia’s legal rights to serve
    the areas in dispute. Count Three requests that the court enjoin Johnston
    from violating section 1926(b). Count Four requests that the court create
    a constructive trust conveyed to Xenia for Johnston’s water infrastructure
    in the areas in dispute.   Count Five requests money damages.         In its
    January 18 Answer to the Amended Complaint, Johnston asserted nine
    affirmative defenses as well as a two-count counterclaim seeking a
    declaratory judgment as to the legal rights between Xenia and Johnston
    and an injunction against Xenia.
    On June 12, Xenia moved for partial summary judgment on grounds
    that federal law preempted any conflicting provisions in Iowa Code
    section 357A.2.    On July 18, Johnston moved for partial summary
    judgment on that preemption claim. On January 8, 2020, Xenia filed a
    second motion for summary judgment on other issues. The court held a
    hearing on the first two motions on February 11. In a March 19 order, the
    court granted partial summary judgment for Xenia as to areas in dispute
    beyond two miles from Johnston’s city limits.          The court granted
    Johnston’s motion for partial summary judgment and denied in part
    Xenia’s first motion for partial summary judgment as to areas within two
    miles of Johnston’s city limits. The ruling was based in significant part on
    Iowa Code section 357A.2’s two-mile rule.
    8
    Xenia filed an interlocutory appeal, which the United States Court
    of Appeals for the Eighth Circuit dismissed for lack of jurisdiction. Xenia
    then filed a Motion for Reconsideration, challenging the court’s
    interpretation of Iowa law in the summary judgment order. Xenia argues
    that when it reorganized into a rural water district from a nonprofit
    corporation, it retained the legal rights it possessed as a nonprofit to
    provide water service anywhere within the state of Iowa (that is, it has dual
    status as a rural water district and a nonprofit corporation, and it has the
    legal rights available to both entities).             Xenia also argues the 2014
    amendment to section 357A.2(4) “clarified that the Two-Mile Rule was
    never intended to preclude a district from extending service within its
    existing boundaries/service area, which under Iowa law, is established by
    the County Board of Supervisors.”
    The court noted the absence of state-court authority interpreting
    Iowa Code section 357A.2. The court granted leave to amici curiae to file
    a brief in support of Xenia’s position. Amici curiae contend that the court’s
    resolution of novel questions of Iowa state law “will have far-reaching
    effects” for rural water service throughout Iowa. Both Xenia and Johnston
    as well as Xenia’s amici curiae agreed the court should certify questions
    to our court.2 On August 4, 2020, the court entered an order certifying
    the three questions of state law to our court.
    II. Our Discretion to Answer Certified Questions.
    “Iowa Code section 684A.1 allows this court to answer questions of
    Iowa law certified to us by a federal court that concludes controlling
    precedent is lacking when the answer may be determinative of the federal
    proceeding.” Bd. of Water Works Trs. of the City of Des Moines v. SAC Cnty.
    2The   Iowa League of Cities had not filed an amicus brief in the certifying court.
    9
    Bd. of Supervisors, 
    890 N.W.2d 50
    , 56 (Iowa 2017) (quoting Oyens Feed &
    Supply, Inc. v. Primebank, 
    808 N.W.2d 186
    , 188 (Iowa 2011)).
    In Foley [v. Argosy Gaming Co.], we noted our discretion to
    answer certified questions that (1) were certified by a proper
    court, (2) presented questions of Iowa law, (3) “may be
    determinative of the cause . . . pending in the certifying
    court,” and (4) appeared to the certifying court to have no
    controlling Iowa precedent.
    
    Id.
     (quoting Foley, 
    688 N.W.2d 244
    , 246 (Iowa 2004)).
    All four requirements are met here. The federal court certified three
    questions of Iowa law that have no controlling Iowa precedent.           The
    answers to the certified questions may be determinative of the competing
    claims in the federal court litigation over the rights to serve the areas in
    dispute within two miles of Johnston’s city limits. More broadly, the Iowa
    League of Cities advises that our decision on the certified questions “will
    directly and immediately affect development and projects now being
    discussed or constructed . . . by many of the cities in this State [and] will
    immediately affect [their] annexation decisions . . . .” Conversely, Xenia’s
    amici caution that “the economic viability of the rural water utilities . . .
    are threatened when cities encroach on the utilities’ service areas.” We
    elect to answer the certified questions.
    III. Analysis.
    We address the certified questions mindful of federal statutory
    protections for rural water districts, which both sides and their amici have
    briefed to our court. See Roth v. Evangelical Lutheran Good Samaritan
    Soc’y, 
    886 N.W.2d 601
    , 611–12 (Iowa 2016) (interpreting Iowa statute to
    avoid conflict with federal law).
    Under the Consolidated Farm and Rural Development
    Act, the USDA is ‘authorized to make or insure loans’ to rural
    water and sewer utilities for the “conservation, development,
    use, and control of water . . . primarily serving farmers,
    10
    ranchers, farm tenants, farm laborers, rural businesses, and
    other rural residents.”
    Green Valley Special Util. Dist. v. City of Schertz, 
    969 F.3d 460
    , 475 (5th
    Cir. 2020) (en banc) (quoting 
    7 U.S.C. § 1926
    (a)(1)).
    “To ensure that federally indebted utilities repay their loans,
    Congress enacted a provision protecting utilities from curtailment and
    encroachment by municipalities and other public bodies.” 
    Id.
     Specifically,
    “Congress enacted section 1926(b) to encourage rural water development
    and to provide greater security for [federal] loans.” Rural Water Sys. No. 1
    v. City of Sioux Ctr., 
    202 F.3d 1035
    , 1038 (8th Cir. 2000). That statute
    states:
    The service provided or made available through any such
    association shall not be curtailed or limited by inclusion of the
    area served by such association within the boundaries of any
    municipal corporation or other public body, or by the granting
    of any private franchise for similar service within such area
    during the term of such loan; nor shall the happening of any
    such event be the basis of requiring such association to secure
    any franchise, license, or permit as a condition to continuing
    to serve the area served by the association at the time of the
    occurrence of such event.
    
    7 U.S.C. § 1926
    (b) (emphasis added). Federal appellate courts recognize
    this provision protects the rural water district’s existing facilities already
    providing service to customers:
    The statute’s use of phrases like ‘curtailed’ and ‘limited’ to
    describe the municipality’s interference with the rural water
    association suggests that a rural water association must
    already be providing service to an area before the protections
    of § 1926(b) apply.
    Le-Ax Water Dist. v. City of Athens, 
    346 F.3d 701
    , 708 (6th Cir. 2003).
    “Section 1926(b) provides a shield, not a sword.” Pub. Water Supply Dist.
    No. 3 of Laclede Cnty. v. City of Lebanon, 
    605 F.3d 511
    , 519 (8th Cir. 2010).
    Courts have rejected “a rural water district’s attempt to use § 1926(b) to
    become the exclusive service provider for a new development that it had
    11
    not previously served.” Id. at 518. That is, rural water districts may use
    the statute defensively—“to protect their exclusive right to serve their
    existing customer base during the time of the qualifying federal loan,
    thereby ensuring the continued security of the loan”—but not offensively
    to move into new territory. Id. at 517–19. “[A]ny ‘[d]oubts about whether
    a water association is entitled to protection from competition under
    § 1926(b) should be resolved in favor of the [USDA]-indebted party seeking
    protection for its territory.’ ”   Id. at 515 (second alteration in original)
    (quoting Rural Water Sys. No. 1, 202 F.3d at 1038).
    “To qualify for protection, an entity must: (1) be an ‘association’
    under the statute, (2) have a qualifying federal loan, and (3) have provided
    or made service available to the disputed area.”        Id. at 521.   “Making
    service available has two components: (1) the physical ability to serve an
    area; and (2) the legal right to serve an area.” Id. (quoting Rural Water Sys.
    No. 1, 202 F.3d at 1037). To determine a physical ability to serve, courts
    use the “pipes in the ground” test, which asks “whether a water association
    ‘has adequate facilities within or adjacent to the area to provide service to
    the area within a reasonable amount of time after a request for service is
    made.’ ” Id. at 523 (quoting Sequoyah Cnty. Rural Water Dist. No. 7 v. Town
    of Muldrow, 
    191 F.3d 1192
    , 1202 (10th Cir. 1999)).          “A utility cannot
    satisfy that test if it has no nearby infrastructure. But ‘pipes in the ground’
    is a colloquial shorthand, not a strict requirement.” Green Valley Special
    Util. Dist., 969 F.3d at 477.
    To determine whether the rural water district has a legal right to
    serve an area, courts refer to state law. Rural Water Sys. No. 1 v. City of
    Sioux Ctr., 
    967 F. Supp. 1483
    , 1525 (N.D. Iowa 1997), aff’d, 
    202 F.3d 1035
    (8th Cir. 2000). The association’s “protected service area is defined by
    state law as of the date” when the federal debt is assumed. 
    Id. at 1530
    .
    12
    Against this backdrop, we address the certified questions.
    Question 1: Whether an Iowa Code § 357A.2 rural water district,
    before amendments to § 357A.2(4) in 2014, had a legal right to
    provide water service to portions of an area described in its count[y]
    board of supervisors resolution, see Iowa Code § 357A.2(1), when
    those portions were also within two miles of the limits of a
    municipality, § 357A.2(3), and when the municipality had not waived
    its rights to provide water service to the area, see § 357A.2(4).
    Xenia argues an affirmative answer to the first question is required
    by the 1990 resolution of the PCBOS. That resolution created the “Xenia
    Rural Water District with all of the rights, powers and duties specified in
    Chapter 357A of the code of Iowa, as amended.” Johnston argues the two-
    mile rule codified in section 357A.2 since 1987 compels us to answer “no”
    to this question. We agree with Johnston.
    We begin with the statutory text. The Iowa legislature enacted the
    two-mile rule in 1987 by adding a new paragraph to Iowa Code section
    357A.2. 1987 Iowa Acts ch. 109, § 2 (codified at Iowa Code § 357A.2 (1987
    Supp.)). The new paragraph stated:
    Water services, other than water services provided as of
    April 1, 1987, shall not be provided within two miles of the
    limits of a city by a rural water district incorporated under this
    chapter or chapter 504A unless the city has approved a new
    water service plan submitted by the district. If the new water
    service plan is not approved by the city, the plan may be
    subject to arbitration.
    Iowa Code § 357A.2 (1987 Supp.) (emphasis added). Section 357A.2 was
    amended again in 1992 to delete the arbitration provision and add notice-
    of-intent procedures for a rural water district. 92 Iowa Acts ch. 1015, §§ 3,
    4 (codified at Iowa Code § 357A.2 (1993)). As amended, the sections reads:
    Water services, other than water services provided as of
    April 1, 1987, shall not be provided within two miles of the
    limits of a city by a rural water district incorporated under this
    chapter or chapter 504A except as provided in this section.
    13
    A rural water district incorporated under this chapter
    or chapter 504A may give notice of intent to provide water
    service to a new area within two miles of a city by submitting
    a water plan to the city. . . . In responding to the plan, the
    city may waive its right to provide water service within the
    areas designated for service by the rural water district, or the
    city may reserve the right to provide water service in some or
    all of the areas which the rural water district intends to serve.
    If the city reserves the right to provide water service within
    some or all of the areas which the rural water district intends
    to serve, the city shall provide service within four years of
    receipt of the plan. This section does not preclude a city from
    providing water service in an area which is annexed by the
    city.
    Iowa Code § 357A.2 (1993) (emphasis added).
    Under the plain meaning of section 357A.2, cities retained the right
    to provide new water services to unserved areas within two miles of the
    city limits. Rural water districts could provide service to new areas within
    two miles of the city limits only upon the city’s approval (waiver) or if the
    city failed to provide service within four years of the district’s notice of
    intent. There were no further substantive amendments to section 357A.2
    before 2014.
    Iowa Code section 357A.2 authorizes county supervisors to
    incorporate and organize rural water districts
    encompassing an area, not then included in any other district,
    in any county or any two or more adjacent counties for the
    purpose of providing an adequate supply of water for domestic
    purposes to residents of the area who are not served by the
    water mains of any city water system . . . .
    Iowa Code § 357A.2 (1987 Supp.).       The rural water district’s “area” of
    operation is subject to the two-mile rule, which has been included within
    section 357A.2 since 1987. Compare id., with id. § 357A.2(3) (2021).
    Xenia and its amici argue the 1990 PCBOS resolution defines
    Xenia’s service territory and only excludes land within city limits, thereby
    allowing Xenia to serve areas outside the city but within two miles of the
    14
    municipal boundary.3 In our view, this argument fails for two reasons.
    First, the 1990 PCBOS resolution expressly provides that Xenia is subject
    to the “duties specified in Chapter 357A” that include the two-mile rule.
    Indeed, as the certifying court observed in its summary judgment ruling,
    [T]here is no conflict between the resolution and state law
    because the resolution explicitly indicates that Xenia is
    established “with all of the rights, powers and duties specified
    in Chapter 357A.” One of those duties was the obligation not
    to provide water service within two miles of a city’s limits
    without receiving the city’s permission. Xenia’s boundaries
    within Polk County are not set in stone by the geographic
    description in the resolution but are instead subject to the
    caveat of the two-mile rule.
    (Citation omitted.)
    Second, a county’s home rule powers may not conflict with a state
    statute. Iowa Const. art. III, § 39A (“Counties . . . are granted home rule
    power and authority, not inconsistent with the laws of the general
    assembly . . . .”). Nothing in chapter 357A authorizes counties to override
    the two-mile rule. Conflicting language in a county ordinance or resolution
    must yield to the controlling state statute. Worth Cnty. Friends of Agric. v.
    Worth Cnty., 
    688 N.W.2d 257
    , 262–64 (Iowa 2004) (holding statute
    preempted conflicting county ordinance regulating livestock confinement
    operations).      As the certifying court aptly observed in its summary
    judgment ruling:
    Read together, the provisions of Iowa Code § 357A.2
    plainly indicate that a rural water district’s permitted service
    area, as specified by its county supervisors’ resolution, is
    subject to the two-mile rule. The two-mile rule’s placement in
    the statute immediately after the provisions permitting
    petitions for the creation of rural water districts shows that
    3It makes sense that the resolution specifically excludes land within a city, where
    the rural water district cannot provide service, without separately mentioning land
    outside the city but within two miles of the city limits. Rural water districts may provide
    service within that two-mile zone with the city’s consent or if the city itself fails to provide
    service within the statutory deadline after the district’s notice of intent.
    15
    the two-mile rule is meant to restrict the potential scope of
    rural water district service areas. If a rural water district’s
    boundaries specified in a resolution trumped the two-mile
    rule, then the two-mile rule would be superfluous—its only
    function is to limit districts’ rights to provide water service
    within two miles of a city’s limits.4
    We agree, and we reject Xenia’s interpretation that would render the two-
    mile rule superfluous.
    We also reject Xenia’s contention in its briefing to our court that
    Johnston’s interpretation of the two-mile rule in section 357A.2 would be
    preempted by 
    7 U.S.C. § 1926
    (b). A water district’s legal right to serve a
    new development is determined by state law. Rural Water Sys. No. 1, 
    967 F. Supp. at 1525
    . Xenia had no pipes in the ground, existing facilities, or
    customers it was already serving within two miles of Johnston’s city limits
    before the two-mile rule went into effect in 1987—and still does not as of
    today. As we discuss above, section 1926(b) operates as a shield to protect
    a rural water district’s existing customer base, not as a sword to strike
    down a state statutory obstacle to legally serve a new area. See Pub. Water
    Supply Dist. No. 3 of Laclede Cnty., 
    605 F.3d at
    517–19. In our view, the
    certifying court correctly rejected Xenia’s preemption argument in its
    ruling granting Johnston’s motion for partial summary judgment:
    In sum, Xenia’s protected service area as of 1982 was
    not defined by the two-mile rule because the two-mile rule
    explicitly exempts water services provided before 1987 and the
    two-mile rule did not begin to apply to Xenia until 1990, but
    that protected service area does not cover the areas in dispute.
    Any expansion of Xenia’s protected service area from loans
    taken out in 1992 or later is defined by the two-mile rule, but
    § 1926(b) does not preempt the two-mile rule in such
    situations because § 1926(b) necessarily looks to state law to
    prospectively define a rural water provider’s service area at the
    time the provider assumes a qualifying loan. As applied to the
    4This discussion related to section 357A.2 as amended in 2014; but the statute
    in 1990 also included the two-mile rule immediately after the general grant of authority
    to the board of supervisors.
    16
    facts of this case, § 357A.2 does not conflict with § 1926(b),
    and federal law therefore does not preempt the two-mile rule.
    We agree with the foregoing legal conclusion. Xenia’s interpretation would
    rewrite section 357A.2 to eliminate the two-mile rule. We decline to do so.
    Finally, we are not persuaded by Xenia’s “dual status” or
    retroactivity arguments, which we address below.           We answer “no” to
    Question 1.
    Question 2: Whether Iowa Code § 357A.2(4), as amended by the Iowa
    legislature in 2014: (a) exempts a rural water district from following
    notice-of-intent procedures when the area the district seeks to serve
    is within the district’s boundaries as designated in the county board
    of supervisors’ resolution creating the water district, and/or
    (b) otherwise provides the rural water district a legal right to serve
    such areas when the municipality has not waived its rights. If so,
    whether the 2014 amendment to § 357A.2(4) had retroactive effect.
    We begin our analysis with the text of the amendment. In 2014, the
    Iowa legislature amended sections 357A.2(3) and (4).          2014 Iowa Acts
    ch. 1086, § 2 (codified at Iowa Code § 357A.2(3)–(4)(a) (2015)).             As
    amended, the statute provides, in relevant part and with amended portions
    italicized, the following:
    3. Water services, other than water services provided
    as of April 1, 1987, shall not be provided within two miles of
    the limits of a city by a rural water district incorporated under
    this chapter except as provided in this section. Except as
    otherwise provided in this chapter, a rural water association
    shall not provide water services within two miles of a city, other
    than water services provided as of July 1, 2014.
    4. a. A rural water district or rural water association
    may give notice of intent to provide water service to a new area
    within two miles of a city by submitting a water plan to the
    city. This subsection shall not apply in the case of a district or
    association extending service to new customers or improving
    existing facilities within existing district or association service
    areas or existing district or association agreements. If water
    service is provided by a city utility established under chapter
    388, the water plan shall be filed with the governing body of
    that city utility. The district or association shall provide written
    notice pursuant to this subsection by certified mail.
    17
    Iowa Code § 357A.2(3)–(4)(a) (2015) (emphasis added). The other amended
    subsections contain the specific notice-of-intent procedures.         See id.
    § 357A.2(4)(b)–(d) (describing specific procedures by which the rural water
    district submits a water plan to the city and the city can waive or reserve
    its rights).
    Xenia, again relying on the PCBOS resolution, contends its “existing
    district or association service areas” within the meaning of the 2014
    amendment include the areas in dispute within two miles of Johnston’s
    city limits. Xenia thereby argues that it avoids the two-mile rule and that
    the 2014 amendment applies retroactively.         Johnston argues the new
    exception is inapplicable in this case because Xenia’s “existing service
    area” omits land within two miles of the city limits and further argues the
    amendment applies only prospectively. In our view, Johnston prevails.
    As we determined above, Xenia’s territorial rights under the 1990
    PCBOS resolution are subject to the two-mile rule in section 357A.2(3).
    The two-mile rule remains in the statute as amended in 2014. The new
    exception to notice requirements in subsection 4 applies when a rural
    water district adds new customers to or improves existing facilities in its
    existing service area or pursuant to an existing agreement. Xenia has no
    customers it is already serving or pipes in the ground (existing facilities)
    in the areas in dispute and lacks an existing agreement to serve those
    areas.
    The legislature did not define “existing service area.” See Iowa Code
    § 357A.1 (defining other terms, but not “existing service area” or “service
    area”). “We give words their ordinary and common meaning by considering
    the context within which they are used, absent a statutory definition or an
    established meaning in the law.” Doe v. Iowa Dep’t of Hum. Servs., 786
    
    18 N.W.2d 853
    , 858 (Iowa 2010).                 We agree with the certifying court’s
    interpretation:
    The ordinary meaning of extending service and improving
    existing facilities within existing service areas suggests that
    the amended language does not contemplate a rural water
    district expanding its provision of water service to areas which
    it previously did not serve.
    Our interpretation of the 2014 statutory exception for existing service
    areas is congruent with federal protection for existing operations under 
    7 U.S.C. § 1926
    (b), as explained above.
    We also consider the context in which this phrase is used, including
    neighboring sections, to determine meaning.                   Doe, 786 N.W.2d at 858
    (“When we interpret a statute, we assess the statute in its entirety, not just
    isolated words or phrases.”).             The amended language at issue is in
    subsection 4, not in subsection 3. Thus, subsection 4(a) does not provide
    an exception for rural water districts to avoid the two-mile rule as set out
    in subsection 3 but only to avoid (in certain circumstances) the notice-of-
    intent procedures in subsection 4.5 As the certifying court noted, “The
    Iowa legislature did not intend to abrogate subsection 3’s two-mile rule by
    placing the relevant amended language in the middle of the next
    subsection in the statute.”
    We construe statutes to avoid rendering part of the text superfluous.
    See Doe, 786 N.W.2d at 858. Under Xenia’s proposed interpretation, as
    the certifying court correctly concluded, “the two-mile rule would not apply
    5The   exception to the notice requirement in subsection 4(a) would come into play
    when a rural water district is already serving customers within two miles of the city limits
    by agreement of the city, by default after the city failed to extend service to the area within
    the statutory deadline, or through facilities installed before 1987 and therefore exempt
    from the two-mile rule. As the League of Cities argues, “[The new exception applies] to
    ‘existing,’ not new, water services and infrastructure. No notice is needed if a district or
    association has pipes and infrastructure in the ground and wants to improve that
    infrastructure or wants to connect new customers to already existing infrastructure and
    pipelines.”
    19
    within a rural water district’s boundaries as established by its county
    supervisors’ resolution . . . [and] it is unclear when the two-mile rule would
    ever apply.” We reject Xenia’s interpretation that would render the two-
    mile rule in section 357A.2(3) superfluous.            And as we explain under
    Question 3, Xenia’s “dual status” territorial argument fails to override the
    two-mile rule.
    We find no support for Xenia’s interpretation in the legislative
    history of the 2014 amendment.            Doe, 786 N.W.2d at 858 (“We also
    consider the legislative history of a statute, including prior enactments,
    when ascertaining legislative intent.”). The Iowa League of Cities notes
    that it and the Iowa Association of Municipal Utilities supported the
    amendment, and it credibly argues both organizations would have
    opposed any change to section 357A.2 that eliminated the two-mile rule.
    The explanation accompanying the 2014 amendment simply reads: “The
    Act also provides standards and procedures governing the rights of cities
    and rural water districts or associations to provide water service within
    areas designated within a water plan.”               Iowa Gen. Assemb., 2014
    Summary of Legislation 141 (2014),            https://www.legis.iowa.gov/docs/
    publications/SOL/401833.pdf#HF2192 [https://perma.cc/9F8U-4WJQ].
    If the amendment actually eliminated the two-mile rule, the accompanying
    bill explanation surely would have said so.6 It did not.
    The 2014 amendment retains the primary right of cities to control
    water service within two miles of their boundaries, thereby allowing room
    for cities to expand. Rural water districts and municipalities can negotiate
    which entity will provide service for new developments under the
    6See  Star Equip., Ltd. v. Iowa Dep’t of Transp., 
    843 N.W.2d 446
    , 454 n.3 (Iowa
    2014) (discussing legislative rules and the Iowa Bill Drafting Guide and Style Manual
    requiring bill explanations to be “concise and accurate”).
    20
    procedures set forth in Iowa Code section 357A.2(4). Indeed, that is what
    happened with these parties in 2018—they negotiated an agreement
    regarding extending water service to a new naval facility.                         Xenia
    contractually agreed that year that it was subject to the two-mile rule. 7
    Elimination of the two-mile rule would undermine the legal certainty
    necessary to promote municipal investments in costly infrastructure
    (pipes in the ground, water towers, pumping stations, and the like). Xenia,
    in Count 4 of its Amended Complaint, asks the federal court to impose a
    constructive trust in favor of Xenia to take over Johnston’s existing
    infrastructure already serving customers in the areas in dispute.                    The
    Eighth Circuit rejected a similar attempt and warned that if a rural water
    district is allowed to “capture customers” already served by the
    municipality,
    cities would not be willing to invest in the necessary
    infrastructure to serve customers within a rural district’s
    boundaries because such investments would be rendered
    worthless by a rural water district that obtains a qualifying
    federal loan. Creating such a disincentive would undermine
    the purpose of encouraging rural utility development.

    605 F.3d at 518
    . The same
    is true here. Based on our interpretation of the 2014 amendment, we
    answer “no” to the first sentence of Question 2, and therefore we need not
    answer the second sentence.
    Question 3: Whether an Iowa Code § 504A nonprofit corporation
    created in 1977 had a legal right to provide water service anywhere
    within the state of Iowa.       If so, whether a § 504A nonprofit
    corporation that reincorporated (including through articles of
    dissolution for the § 504A entity) as a § 357A.2 rural water district in
    1990 retained the legal right to provide water service anywhere
    within the state of Iowa (including outside its boundaries as specified
    7Xenia in this litigation contends it misread section 357A.2 in 2018 to mistakenly
    conclude the two-mile rule applied to it. In our view, Xenia’s 2018 conclusion was correct
    and its current position is mistaken.
    21
    in its county board of supervisors resolution and within two miles of
    a municipality), prior to and following the 1991 amendment to
    § 357A.2.
    We now confront Xenia’s “dual status” argument.               Xenia was
    originally incorporated in 1977 as a nonprofit corporation under Iowa Code
    chapter 504A, and it was reincorporated in 1990 under Iowa Code chapter
    357A. Xenia contends that as a chapter 504A entity, it could operate
    anywhere in the state of Iowa and that after its reorganization under
    chapter 357A, it retained a dual status with a continuing power to operate
    anywhere in Iowa, including within two miles of Johnston’s city limits.
    Xenia’s dual status argument fails for several reasons.
    First, the argument rests on a flawed premise—that Xenia could put
    pipes in the ground and serve water customers anywhere in Iowa as a
    chapter 504A corporation.      Xenia’s interpretation would contradict the
    statutory rights of other entities. See, e.g., 
    Iowa Code § 357.28
     (1977)
    (requiring consent of trustees of beneficial water district to construct
    additional water mains within its territory).       Moreover, under section
    357A.2, the 504A corporation would be subject to the two-mile rule. See
    Iowa Code § 357A.2 (1987 Supp.); see also Rural Water Sys. No. 1, 202
    F.3d at 1038 (“It is likely that section 357A.2 applied to these corporations
    having dual status.”).
    In any event, Xenia’s rights under chapter 504A were extinguished
    when it reorganized under chapter 357A. See Iowa Code § 357A.20(1)–(2)
    (1991 Supp.) (providing that upon filing a notice of dissolution with the
    secretary of state, “the nonprofit corporation shall cease to exist as a chapter
    504A entity and all assets and liabilities of the nonprofit corporation become
    the assets and liabilities of the newly organized district without a need for
    any further meetings, voting, notice to creditors, or other actions by the
    22
    members or board”);8 see also Rural Water Sys. No. 1, 202 F.3d at 1038 n.7
    (“Although the district may continue to operate under the bylaws and
    articles of incorporation of the 504A corporation, it is no longer a 504A
    corporation once it is reincorporated [under section 357A.2].”).                Xenia’s
    board signed articles of dissolution of the 504A entity in 1991 and filed them
    with the Iowa Secretary of State. And as noted, the PCBOS resolution that
    incorporated Xenia under section 357A.2 expressly subjected Xenia to the
    duties of that chapter, which include the two-mile rule.
    We hold that an Iowa Code section 504A nonprofit corporation
    created in 1977 did not have a legal right to provide water service anywhere
    within the state of Iowa, and therefore we answer “no” to the first sentence
    of Question 3. We further hold that any broader territorial rights under
    chapter 504A were abandoned when the entity dissolves and reincorporates
    under chapter 357A as a rural water district subject to the two-mile rule.
    We therefore answer “no” to second sentence of Question 3 as well.
    VI. Conclusion.
    For the reasons explained in this opinion, we answer the three
    certified questions as set forth above.
    CERTIFIED QUESTIONS ANSWERED.
    All justices concurred except McDermott, J., who takes no part.
    8Xenia and its amici argue Iowa Code section 357A.20(2)(b) is inapplicable
    because that statute was enacted in 1991, after Xenia reorganized, and does not apply
    retroactively. See 1991 Iowa Acts ch. 134, § 17 (codified at Iowa Code § 357A.20 (1991
    Supp.)). We decline to interpret the statute to grandfather in and preserve a dual status
    for a 504A entity that dissolved after reorganizing under section 357A.2. We apply the
    provision prospectively to defeat the dual status Xenia claims today. As the certifying
    court ruled, “Even if Xenia had the legal ability to provide water service everywhere in
    Iowa when it was a nonprofit, Xenia did not retain that right upon reorganization.”
