  •                  IN THE SUPREME COURT OF IOWA
    No. 47 / 04-0643
    Filed April 7, 2006
    K & W ELECTRIC, INC.,
    Appellant,
    vs.
    STATE OF IOWA,
    Appellee.
    Appeal from the Iowa District Court for Black Hawk County,
    Leonard D. Lybbert, Judge.
    Property owner appeals dismissal of tort and inverse condemnation
    claims against State. AFFIRMED.
    John J. Hines of Dutton, Braun, Staack, Hellman, P.L.C., Waterloo,
    for appellant.
    Thomas J. Miller, Attorney General, and Noel C. Hindt and Richard E.
    Mull, Assistant Attorneys General, for appellee.
    2
    TERNUS, Justice.
    The appellant, K & W Electric, Inc., appeals an adverse summary
    judgment ruling on its damage claims against the appellee, State of Iowa. K
    & W sued the State on theories of negligence, violation of Iowa Code section
    314.7 (1999), and inverse condemnation, claiming a highway construction
    project undertaken by the Iowa Department of Transportation (DOT) in the
    vicinity of the plaintiff’s premises caused flooding that damaged the
    plaintiff’s property. The district court held the plaintiff’s claims were time
    barred, see Iowa Code § 614.1(4), and the defendant was immune from tort
    liability under Iowa Code section 669.14(8). We affirm.
    I. Facts and Prior Proceedings.
    The plaintiff is an electrical contractor whose place of business is at
    1127 Lincoln Street in Cedar Falls, Iowa. Its business premises include a
    large steel building that houses an office, shop, and storage facilities. The
    plaintiff’s property is located in the 100-year flood plain of the Cedar River
    near a diversion channel of the river.
    The Cedar River has a long history of flooding in Cedar Falls, with the
    highest recorded flood prior to the events giving rise to this litigation
    occurring in 1961. In 1984, the Federal Emergency Management Agency
    (FEMA) prepared a flood insurance study of the city to investigate the
    existence and severity of flood hazards and to assist the community in
    promoting sound flood plain management. The study included a flow-
    frequency analysis, flood profiles, and floodways for each channel.         A
    floodway, according to the FEMA report, “is the channel of a stream plus
    any adjacent flood plain areas that must be kept free of encroachment so
    that the 100-year flood can be carried without substantial increases in flood
    heights.” Under federal standards, a substantial increase is an increase in
    excess of one foot.
    3
    In the early 1990s, the DOT undertook an extensive highway
    construction project involving multiple interchanges between highways 218,
    58, and 57 over and near the Cedar River and the Cedar River diversion
    channel. Some of these structures were just a short distance from the
    plaintiff’s property. Using data from the FEMA report, engineers designed
    the bridges and structures crossing the river and diversion channel to span
    the floodway without increasing a 100-year flood by more than one foot.
    The designs were approved by the Iowa Department of Natural Resources,
    and the project was constructed according to design.
    In April 1993 heavy rainfall and snowmelt caused a flood that
    matched the record 1961 flood. During this flood, the plaintiff’s land was
    covered by floodwaters of substantial depth. Only the building, which had
    been built on an elevation approximately one foot above the 100-year flood
    level established by the Cedar Falls flood plain maps, remained above flood
    level, but barely so. A second flood occurred in August 1993, but the flood
    crest was about two feet less than the April flood.
    In the aftermath of the extensive flooding in 1993, the DOT sponsored
    a flood study conducted by Rust Environment and Infrastructure, Inc. The
    purpose of the study was to review the flooding characteristics of the Cedar
    River in light of data collected from the 1993 floods and to determine the
    effects of highway construction in the area. (The report stated that at the
    time of the April 1993 flood, “the majority of the highway improvements
    were in place.”) The “Cedar River Flood Plain Study,” hereinafter “the Rust
    report,” was published on January 25, 1994. The report asserted that the
    availability   of   “actual   flood   high-water   elevations   and   discharge
    measurements” from the 1993 floods had “resulted in the most reliable
    computer model ever developed for the Cedar River study area.”
    4
    Of significance to the present lawsuit, the report found that the
    effects of construction were significant in the diversion channel and its
    vicinity, an area that included the plaintiff’s business. Three factors were
    identified as leading to an increased water flow in the diversion channel: (1)
    backwater created by the highway 218 bridge over the diversion channel; (2)
    backwater created by bridges on the main channel; and (3) construction of
    West Lake, which removed a portion of Big Woods Road, creating a less
    resistant flow path for water to enter the diversion channel. The report
    concluded, however, that “[a]ll highway structures were sized based on
    information available at the time of the specific project.”     It noted the
    structures for highway 58 and highway 218 through the diversion channel
    spanned the floodway as identified in the FEMA report. In addition, the
    Rust report stated that based on the model in use when the improvements
    were designed, the increase in the floodways was anticipated to be
    approximately one foot. In actuality, the increase was greater, particularly
    in the area of the plaintiff’s business.
    In March 1994, shortly after the Rust report was released, K & W filed
    a claim with the state appeal board, seeking recovery for damage to a truck
    caused by the April 1993 flood. In relevant part, its claim stated:
    Our construction business, located at 1127 Lincoln
    Street, Cedar Falls, was completely surrounded by flood waters
    on April 2, 1993. The flood waters were caused by highway
    construction in the area.
    In order to keep our business in operation, we used our
    big heavy duty trucks to transport employees and material
    from our place of business, thru the flood waters, to our job
    sites and to our customers. We used the International Truck
    to go thru the flood water and it developed engine and rear end
    trouble.
    K & W claimed approximately $5600 in damages. The claim was denied,
    however, and K & W did not pursue further litigation against the State.
    5
    On July 22, 1999, heavy rains hit northern Iowa, causing a flood on
    the Cedar River. K & W’s property was again flooded. This time, however,
    water entered the plaintiff’s building, causing extensive damage and
    necessitating significant cleanup efforts. On January 31, 2000, K & W filed
    a tort claim against the State for property damage in excess of $32,000.
    The plaintiff again claimed the flooding and resultant damages were caused
    by the effects of highway construction.     K & W alleged the State was
    negligent, and it specifically referred to the Rust report and the three
    construction-related factors identified there as having increased the water
    flow in the diversion channel. In addition to damages, the plaintiff asked
    that a plan be developed to protect its property and that the State pay for
    construction of the solution. The appeal board denied K & W’s claim.
    This lawsuit was filed on June 11, 2001. The plaintiff reasserted its
    negligence claim, alleging the DOT failed to exercise due care in the design
    and construction of the highway projects in the vicinity of the plaintiff’s
    facility. In addition, K & W contended the DOT’s construction activities
    violated Iowa Code section 314.7, which requires that contractors must “use
    strict diligence in draining the surface water from the public road in its
    natural channel” when improving any highway.          Finally, the plaintiff
    claimed a permanent devaluation of its property, resulting in an inverse
    condemnation.
    The State subsequently filed a motion for summary judgment on
    several grounds, but only two are pertinent to this appeal: (1) the design-
    and-construction immunity of Iowa Code section 669.14(8) applies to the
    plaintiff’s tort claims because the project design complied with generally
    accepted engineering standards, and the highways were constructed in
    accordance with the design specifications; and (2) the plaintiff’s inverse
    condemnation claim is barred by the statute of limitations contained in
    6
    Iowa Code section 614.1(4) because K & W was aware of the potential for
    increased flooding since at least the April 1993 flood.      Accepting both
    arguments, the district court granted the State’s motion for summary
    judgment. The plaintiff has appealed.
    II. Scope of Review.
    The district court’s ruling on a motion for summary judgment is
    reviewed for correction of errors of law. See Christy v. Miulli, 
    692 N.W.2d 694
    , 699 (Iowa 2005).
    Summary judgment is appropriate “if the pleadings,
    depositions, answers to interrogatories, and admissions on file,
    together with the affidavits, if any, show that there is no
    genuine issue as to any material fact and that the moving party
    is entitled to a judgment as a matter of law.”
    
    Id. (citation omitted).
    A genuine factual issue “is generated if reasonable
    minds can differ on how the issue should be resolved.”         
    Id. A fact
    is
    material only if its existence would affect the outcome of the suit. Faeth v.
    State Farm Mut. Auto. Ins. Co., 
    707 N.W.2d 328
    , 331 (Iowa 2005).
    To obtain summary judgment, “the moving party must affirmatively
    establish the existence of undisputed facts entitling that party to a
    particular result under controlling law.” Griglione v. Martin, 
    525 N.W.2d 810
    , 813 (Iowa 1994).     In considering whether the moving party has
    satisfied this requirement, we accord the nonmoving party every legitimate
    inference that may be drawn from the record. 
    Faeth, 707 N.W.2d at 331
    . If
    the moving party has met its burden, “[t]he resisting party must set forth
    specific facts showing that a genuine factual issue exists.” Grabill v. Adams
    County Fair & Racing Ass’n, 
    666 N.W.2d 592
    , 594 (Iowa 2003).
    III. Design-and-Construction Immunity.
    We begin with the State’s claim that its statutory waiver of sovereign
    immunity does not apply to the plaintiff’s negligence claims by virtue of the
    7
    exception contained in section 669.14(8). This statute provides that the
    state tort claims act does not apply to
    [a]ny claim based upon or arising out of a claim of negligent
    design or specification, negligent adoption of design or
    specification, or negligent construction or reconstruction of a
    highway, secondary road, or street . . . that was constructed or
    reconstructed in accordance with a generally recognized
    engineering or safety standard, criteri[on), or design theory in
    existence at the time of the construction or reconstruction. A
    claim under this chapter shall not be allowed for failure to
    upgrade, improve, or alter any aspect of an existing highway,
    secondary road, or street, to new, changed, or altered design
    standards.
    Iowa Code § 669.14(8).        This statute gives the DOT “a state-of-the-art
    defense with respect to design and construction of [highways and roads].”
    Connolly v. Dallas County, 
    465 N.W.2d 875
    , 877 (Iowa 1991) (discussing
    comparable exception in municipal tort claims act). It also establishes
    that the extent of the public agency’s duty for purposes of
    establishing nonconstitutional torts is measured by the
    “generally recognized engineering or safety standard, criteri[on],
    or design theory” in existence at the time of the construction or
    reconstruction.
    
    Id. (quoting Iowa
    Code § 613A.4(7), (8) (now found at Iowa Code § 670.4(7),
    (8))).
    To demonstrate the applicability of this immunity, the State
    submitted the affidavit of David Claman, a civil engineer employed by the
    DOT. Claman stated in his affidavit that the hydraulic analysis and the
    design of the highway projects in question were based upon data from the
    1984 FEMA study. He further stated:
    Based on this analysis, the bridges and structures crossing the
    main channel of the Cedar River, and the Cedar River diversion
    channel were sized to span the floodway, defined as the area
    that must be kept free of encroachments so that a 100-year
    flood could be carried without a substantial increase, defined
    as one foot, in flood heights. . . . The project was constructed
    according to design, in accordance with these recognized,
    8
    generally accepted engineering criteria existing at the time of
    the design and construction.
    These statements were corroborated by the Rust report, which stated “[a]ll
    highway structures were sized based on information available at the time of
    the specific project,” the highway structures “through the diversion channel
    were sized to span the . . . floodway,” and “[t]he floodways developed for
    both the diversion channel and the main channel of the Cedar River
    produced approximately 1 foot of increase, as computed by the HEC-2
    hydraulic model” developed from the data compiled in the 1984 FEMA
    study.
    In resistance to the State’s motion for summary judgment, K & W
    submitted the affidavit of William Kehe, a professional engineer with
    experience in hydraulic analysis for the design of bridges, highways, and
    waterways. Kehe did not dispute the findings and conclusions stated in the
    Rust report and the Claman affidavit. Rather, he stated that after reviewing
    the 1994 Rust report, he “[felt] that K & W ha[d] merit in its claim for
    damages against the DOT.” Kehe gave the following explanation for his
    opinion:
    The [Rust] study uses nationally accepted modeling
    methodology validated against the 1993 floods to conclude that
    recent highway construction has raised the level of the Q100
    flood event in nearly all locations. . . . [T]he study clearly
    states that Lincoln Street was most adversely affected with a
    rise of 1.9 feet above the current Flood Insurance Map
    elevation. The study also concludes the major rise in the
    controlling flood elevation was caused by the removal of a
    portion of Big Woods Road thus eliminating an existing
    temporary detention basin along the Diversion Channel.
    Raising any flood elevation by construction more than
    one foot is typically a violation of state and federal laws.
    (Emphasis added.)
    We agree with the district court that Kehe’s affidavit is not sufficient
    to prevent summary judgment on the State’s design immunity defense. A
    9
    review of the record, including the affidavits submitted by the parties,
    reveals the following facts pertinent to the DOT’s state-of-the-art defense are
    essentially undisputed. The highway project was designed so that flood
    levels would rise by no more than one foot. This design was based on a
    hydraulic model that utilized the most current data available at the time of
    the design and construction.      The one-foot increase projected by this
    hydraulic analysis was within acceptable parameters for flood plain
    improvements.     The DOT constructed the highway improvements in
    accordance with the design.       A more accurate hydraulic model was
    developed in 1994 based on the 1993 flood data, data that was not available
    at the time of the design and substantial completion of the DOT project.
    The 1994 model shows the highway project has, in fact, raised the 100-year
    flood level in the vicinity of the plaintiff’s business by more than the one-
    foot rise projected by the models in use prior to 1994. The actual increase
    in flood levels caused by the highway project exceeds federal standards.
    These facts establish the applicability of section 669.14(8) as a matter
    of law.   The plaintiff’s claim is “based upon . . .     negligent design or
    specification, negligent adoption of design or specification, or negligent
    construction or reconstruction of a highway.” Iowa Code § 669.14(8). The
    highway “was constructed or reconstructed in accordance with a generally
    recognized engineering . . . standard, criteri[on], or design theory in
    existence at the time of the construction or reconstruction.” 
    Id. (emphasis added).
    There is no dispute as to these determinative facts. We think this
    case presents a classic scenario for application of the design-and-
    construction immunity.
    The plaintiff contends that even if the highway project was designed
    in accordance with engineering standards, criteria, and design theory
    generally recognized at the time of the design, the DOT was obligated to
    10
    revise its plans when it received the Rust report in January of 1994. The
    record shows the majority of the work on the highway project had been
    completed at the time of the April 1993 flood.         Another season of
    construction passed before the Rust report was issued nine months later.
    We do not think the DOT loses its design immunity when new design
    standards are developed after the majority of the project has been
    completed, particularly in view of the legislature’s express statement that
    “[a] claim under this chapter shall not be allowed for failure to upgrade,
    improve, or alter any aspect of an existing highway, secondary road, or
    street, to new, changed, or altered design standards.”        Iowa Code §
    669.14(8).
    In interpreting statutes, we attempt to avoid an interpretation that
    would lead to absurd or impractical results. See State v. Tesch, 
    704 N.W.2d 440
    , 451 (Iowa 2005). Under the plaintiff’s suggested interpretation of
    design immunity, this statutory protection would be lost if one intersection
    remained to be constructed when additional data became available. This
    interpretation of design immunity would require the DOT to redesign an
    improvement after the work is substantially completed, an impractical
    result given the cost and complexity of such projects. We cannot believe
    this was the legislature’s intent.
    Accordingly, we hold the district court did not err in ruling the DOT
    was immune under section 669.14(8) as a matter of law. The district court
    properly dismissed the plaintiff’s negligence and section 314.7 theories on
    this ground. Because these claims were properly dismissed on the basis of
    design immunity, we do not consider the State’s alternative argument that
    these claims were also barred by the applicable statute of limitations.
    11
    IV. Inverse Condemnation Claim and Statute of Limitations.
    A.   Issue.    We now consider the district court’s ruling that the
    plaintiff’s constitutional takings claim was time barred under Iowa Code
    section 614.1(4), which establishes a five-year statute of limitations for
    “injuries to property . . . and all other actions not otherwise provided for in
    this respect.” Iowa Code § 614.1(4); see also Scott v. City of Sioux City, 
    432 N.W.2d 144
    , 147 (Iowa 1988) (holding inverse condemnation claims are
    subject to five-year statute of limitations). The district court ruled K & W
    had constructive knowledge of its claim after the 1993 flood, and so the
    limitations period commenced at that time. The plaintiff contends the
    statute of limitations did not begin to run until the 1999 flood. At the very
    least, it asserts, there is a factual issue for the jury on when it discovered
    its claim. Alternatively, K & W argues the damage to its property “was in
    the nature of a continuing injury for which recovery was permissible for any
    damages occurring within five years of filing suit.” Before addressing the
    plaintiff’s arguments, it is helpful to understand the nature of an inverse
    condemnation claim.
    B. General principles of inverse condemnation. Inverse condemnation
    is an action pursued by a property owner who claims a governmental entity
    has appropriated all or part of the owner’s property interest without a
    formal condemnation proceeding. Kingsway Cathedral v. Iowa Dep’t of
    Transp., ___ N.W.2d ___, ___ (Iowa 2006); Harms v. City of Sibley, 
    702 N.W.2d 91
    , 97 (Iowa 2005); 9 Patrick J. Rohan & Melvin A. Reskin, Nichols
    on Eminent Domain § 34.03[1], at 34-45 (rev. 3d ed. 2005). Generally, a
    taking does not occur unless the invasion of the property is permanent. 1
    1  There is an exception to this general statement for regulatory takings when the
    offending legislation can be invalidated. See Bormann v. Bd. of Supervisors, 
    584 N.W.2d 309
    , 321 (Iowa 1998). The remedy for such “temporary” takings is to declare the legislation
    invalid, thereby restoring the property owner’s future use and enjoyment of the property,
    and to compensate the property owner for damages occurring before the statute is
    12
    See Kingsway Cathedral, ___ N.W.2d at ___ (“The continuance or permanency
    of the government action sufficient to support the finding of a creation of a
    servitude has been the determining factor for a finding of a taking. . . .
    Absence of such continuance or permanency leaves the property owner with
    nothing but an action in tort.”); cf. Kelley v. Story County Sheriff, 
    611 N.W.2d 475
    , 482 (Iowa 2000) (holding damage to residence door caused by
    police officer executing arrest warrant was not a taking, distinguishing
    cases where there has been “a permanent deprivation of property, or
    creation of a permanent property interest, as contemplated by [the Takings
    Clause in the Iowa Constitution]” (emphasis added)). Thus, when flooding
    results from a government project, “the flooding has been held compensable
    [as a taking] if there is ‘a permanent condition of continual overflow’ or a
    permanent ‘liability to intermittent but inevitably recurring overflows.’ ” 4A
    Julius L. Sackman, Nichols on Eminent Domain § 14.01[2], at 14-6 (rev. 3d
    ed. 2005) (emphasis added); accord Phelps v. Bd. of Supervisors, 
    211 N.W.2d 274
    , 277 (Iowa 1973); 4 Julius L. Sackman, Nichols on Eminent Domain §
    13.16[5], at 13-149 (rev. 3d ed. 2005). When the flooding is intermittent
    rather than continual, the fee remains in the property owner, subject to an
    easement in the governmental entity to overflow the property with water.
    
    Phelps, 211 N.W.2d at 276
    ; cf. Bormann v. Bd. of Supervisors, 
    584 N.W.2d 309
    , 316 (Iowa 1998) (holding statutory nuisance immunity for farm
    operation created “an easement in the property affected by the nuisance” in
    favor of the operator, and constituted a taking).
    Consistent with the permanent character of a taking, the injury
    caused by such governmental action is measured by the diminution in the
    value of the property. See Kingsway Cathedral, ___ N.W.2d at ___ (“What
    must be compensated is diminishment of the value of the land.”); 9 Nichols
    ______________________________________
    invalidated. 
    Id. 13 on
    Eminent Domain § 34.03[3][b], at 34-57. Accordingly, compensation for
    the taking of an easement is the difference in market value of the property
    before and after imposition of the easement. 
    Connolly, 465 N.W.2d at 878
    (stating damages under theory of inverse condemnation include “loss
    caused by the first flooding and future damages, ordinarily determined by
    the difference in the value of the land prior to and after the completion of
    the public improvement”); accord Gacke v. Pork Xtra, L.L.C., 
    684 N.W.2d 168
    , 174-75 (Iowa 2004); 4 Nichols on Eminent Domain § 13.16[5], at 13-
    150; 9 Nichols on Eminent Domain § 34.03[3][b], at 34-57.
    K & W’s inverse condemnation claim is consistent with these
    principles. K & W alleged the DOT “permanently raised the flood levels of
    the diversion channel near [the] plaintiff’s property making it more
    susceptible to overflow into the plaintiff’s plant for an indefinite period of
    time into the future.”    The plaintiff claimed that, “[a]s a result of the
    highway improvements,” its property had lost half its value. K & W sought
    to recover “an amount sufficient to fully compensate [it] for the permanent
    loss in value of its property.” We now consider whether this claim is barred
    by the five-year statute of limitations.
    C. General principles governing application of statute of limitations.
    The five-year limitations period begins to run upon accrual of the
    claim. See Iowa Code § 614.1(4). Generally, a claim accrues when “the
    wrongful act produces injury to the claimant.” 
    Scott, 432 N.W.2d at 147
    .
    This principle is tempered by our discovery rule. See Borchard v. Anderson,
    
    542 N.W.2d 247
    , 250 (Iowa 1996).               Under the discovery rule,
    commencement of the limitations period is delayed “ ‘until the plaintiff
    knows or in the exercise of reasonable care should have known both the
    fact of the injury and its cause.’ ” Rieff v. Evans, 
    630 N.W.2d 278
    , 291
    (Iowa 2001) (quoting Woodroffe v. Hasenclever, 
    540 N.W.2d 45
    , 47 (Iowa
    14
    1995)). In other words, the injured party must have “ ‘actual or imputed
    knowledge of the facts that would support a cause of action.’ ” 
    Id. (quoting State
    v. Wilson, 
    573 N.W.2d 248
    , 253 (Iowa 1998)).
    “Knowledge is imputed to a claimant when he gains
    information sufficient to alert a reasonable person of the need
    to investigate. As of that date he is on inquiry notice of all
    facts that would have been disclosed by a reasonably diligent
    investigation.”
    Perkins v. HEA of Iowa, Inc., 
    651 N.W.2d 40
    , 44 (Iowa 2002) (quoting Ranney
    v. Parawax Co., 
    582 N.W.2d 152
    , 155 (Iowa 1998)).
    D. Accrual of inverse condemnation claim. The State asserts K & W’s
    inverse condemnation claim accrued at the time of the 1993 flood because
    the plaintiff knew of its injury and the cause of its injury at that time. The
    plaintiff argues its inverse condemnation claim did not accrue until the
    1999 flood because (1) it did not discover its claim until then, and (2) it was
    entitled to bring separate, successive actions for each flooding event. Before
    addressing the issue of what K & W knew or should have known after the
    1993 flood, we consider the plaintiff’s contention that each flood gave rise to
    a new claim at which time the statute of limitations began anew.
    In a case involving the flooding of property caused by permanent
    public improvements, this court stated:
    a cause of action for inverse condemnation accrues the first
    time damage occurs to lands or chattels real which was in fact
    caused by the improvement. . . . [T]he person owning the land,
    crops, or either at that time . . . must seek all damages both
    present and future in a single action.

    223 Iowa 229
    , 237-38, 
    272 N.W. 79
    , 83 (1937) (holding because injury to land caused
    by dam was permanent, “an action therefore should have been commenced
    within five years after the completion of the dam or at least within five years
    after the first injury to the property”). The plaintiff claims this statement is
    15
    dicta and contrary to the rule that “flood damage is a continuing wrong in
    which the limitations period runs from the occurrence of each such injury.”
    K & W relies on our decision in Anderson v. Yearous, 
    249 N.W.2d 855
    (Iowa
    1977), a flood case in which we stated:       “Where resultant injuries are
    recurring and successive actions will lie, the limitation period runs from the
    occurrence of each such 
    injury.” 249 N.W.2d at 860
    (emphasis added). As
    an examination of our nuisance cases will illustrate, this rule does not
    apply to actions for inverse condemnation because successive actions will
    not lie for a taking.
    Initially, we note that Anderson was a nuisance case, not an inverse
    condemnation case. In Anderson, the plaintiffs obtained damages and
    injunctive relief from their neighbor—a private landowner—who had
    repaired a levee so as to obstruct the natural water flow, resulting in
    intermittent flooding of the plaintiffs’ land.

    The Anderson case is
    one in a series of decisions by this court discussing when a nuisance or
    injury is temporary or permanent and the ancillary questions of when a
    claim for damages accrues and what the appropriate measure of damages
    is. See, e.g., Weinhold v. Wolff,

    , 
    167 N.W. 623
    (1918). A review of these cases reveals some basic principles that are
    helpful in resolving the statute-of-limitations issue in this case.
    16
    Whether an injured party is entitled to bring successive actions for
    damages or must seek compensation for all injuries in one suit depends on
    the nature of the injury, and to some degree, the nature of the nuisance.
    Where injuries from the nuisance are intermittent rather than continual, a
    property owner may bring successive actions to recover damages for each
    intermittent injury.   See 
    Eppling, 254 Iowa at 404
    , 117 N.W.2d at 825. In
    such cases, “the measure of damages is the diminution in rental value
    caused by the nuisance together with such special damages, as for
    discomfort and annoyance, as may result therefrom.” 
    Miller, 253 Iowa at 1062
    , 114 N.W.2d at 914.
    In contrast,
    “[i]f injuries from a nuisance are of a permanent character and
    go to the entire value of the estate, there can be but one action,
    and all damages—past, present, and future—are recoverable
    therein; in such a case, one recovery is a grant or license to
    continue the nuisance, and there can be no second recovery for
    its continuance.”
    
    Weinhold, 555 N.W.2d at 462
    (quoting 58 Am. Jur. 2d Nuisances § 273
    (1989)); accord Mel Foster Co. Props., 
    Inc., 427 N.W.2d at 175
    ; 
    Nall, 246 Iowa at 840
    , 69 N.W.2d at 533; Wapsipinicon Power 
    Co., 186 Iowa at 527
    , 167
    N.W. at 624. The measure of damages in such a case is the difference in
    market value of the property immediately before and immediately after the
    injury-producing nuisance.     See 
    Weinhold, 555 N.W.2d at 465
    (noting
    special damages may also be recovered); Mel Foster Co. Props., 
    Inc., 427 N.W.2d at 175
    ; Wapsipinicon Power 
    Co., 186 Iowa at 527
    , 167 N.W. at 624.
    As we noted in Weinhold, “[t]his measure of damages compensates the
    injured landowner for an interference that is tantamount to a permanent
    
    taking.” 555 N.W.2d at 465
    .
    It is at once apparent that conduct resulting in inverse condemnation
    is analogous to a nuisance causing permanent injury because the injury for
    17
    which compensation is sought in an inverse condemnation case—loss of the
    plaintiff’s interest in the property—is also permanent in nature.         See
    Kingsway Cathedral, ___ N.W.2d at ___.        Furthermore, the measure of
    damages in an inverse condemnation case—diminution in market value—is
    the same as the measure of damages in a permanent-injury nuisance case.
    In the latter situation, this court has consistently held that all damages
    must be sought in one suit. See, e.g., 
    Connolly, 465 N.W.2d at 878
    ; Mel
    Foster Co. Props., 
    Inc., 427 N.W.2d at 175
    ; 
    Nall, 246 Iowa at 840
    , 69 N.W.2d
    at 533-34; Wapsipinicon Power 
    Co., 186 Iowa at 527
    , 167 N.W. at 624. The
    same conclusion, that only one action will lie, is equally applicable to
    inverse condemnation actions because the resulting injury—a taking of the
    plaintiff’s property interest—can only happen once. Therefore, it is not the
    type of injury for which successive actions will lie. Cf. 
    Scott, 432 N.W.2d at 148
    (holding adverse impact on market value of plaintiff’s property caused
    by city zoning ordinance “constituted a single injury”). Thus, this court was
    correct when it stated in Connolly that in an inverse condemnation case, all
    damages must be sought “in a single 
    action.” 465 N.W.2d at 878
    .
    Because the successive-actions rule does not apply here, the five-year
    statute of limitations for the plaintiff’s inverse condemnation claim did not
    automatically begin anew when the plaintiff’s property was flooded for a
    second time in 1999. Therefore, the pertinent inquiry in this case is: when
    did K & W discover its claim for inverse condemnation? We turn now to a
    discussion of that issue.
    E. Application of discovery rule. In order to succeed on its defense
    that the plaintiff’s inverse condemnation claim is barred by the statute of
    limitations as a matter of law, the State must demonstrate there is no
    dispute that K & W had actual or imputed knowledge of “ ‘the fact of [its]
    injury and its cause’ ” prior to June 11, 1996. See 
    Rieff, 630 N.W.2d at 18
    291. The summary judgment record reveals the plaintiff had actual
    knowledge by March 1994 that the April 1993 flood that invaded its land
    was “caused by highway construction in the area.”         K & W made this
    allegation in the claim it filed with the state appeal board on March 14,
    1994 for damage to its truck. Thus, by that date, the plaintiff knew of an
    injury to its real property and its cause.
    The plaintiff argues, however, that although it knew the DOT’s work
    had caused flooding on its land, it did not know it had been permanently
    injured. See 3 Julius L. Sackman, Nichols on Eminent Domain § 8.01[4][c],
    at 8-60 (rev. 3d ed. 2005) (stating it has been held landowner must institute
    action within prescribed period “after he or she realizes or should
    reasonably realize that his or her property has sustained an injury that is
    permanent in nature” (emphasis added)).         We question whether this
    argument has any validity under Iowa law. This court has held that “[w]hen
    an incident occurs causing minor injuries and later more serious injuries
    appear,” the plaintiff’s claim for all injuries accrues for purposes of the
    statute of limitations upon discovery of the first injury. See LeBeau v.
    Dimig, 
    446 N.W.2d 800
    , 802-03 (Iowa 1989). We have also held “that once
    claimants have knowledge of facts supporting an actionable claim they have
    no more than the applicable period of limitations to discover all the theories
    of action they may wish to pursue in support of that claim.” Sparks v.
    Metalcraft, Inc., 
    408 N.W.2d 347
    , 352 (Iowa 1987).           Whether these
    authorities preclude the plaintiff’s argument is a question we need not
    answer because we are persuaded K & W had imputed knowledge of its
    permanent injury long before June 11, 1996, five years before it commenced
    this action.
    The district court concluded the plaintiff “should have known that as
    a result of [the 1993] flood, the value of its land had been significantly
    19
    lessened.” The court explained the mere fact “the land had been inundated
    by the 1993 flood” would “substantially reduce the overall value of the
    property” in the eyes of prospective buyers. We agree. But even more
    importantly, we also think K & W is charged with knowledge of the
    information set forth in the Rust report, information that made it clear the
    plaintiff’s property was at a greatly increased risk of flooding as a result of
    the DOT’s highway construction.
    In K & W’s 1994 claim filed with the state appeal board, it asserted,
    “The flood waters were caused by highway construction in the area.” We
    conclude it is indisputable that a reasonably diligent investigation of this
    claim would have led the plaintiff to the Rust report. See 
    Perkins, 651 N.W.2d at 44
    (stating injured party is assumed to have knowledge of “ ‘all
    facts that would have been disclosed by a reasonably diligent investigation’ ”
    (citation omitted)); Chrischilles v. Griswold, 
    260 Iowa 453
    , 462, 
    150 N.W.2d 94
    , 100 (1967) (“The question in any case is . . . What might [the plaintiff]
    have known, by the means of information within his reach, with the
    vigilance which the law requires of him?”). This report was prepared for the
    DOT, the entity responsible for the construction, and was published on
    January 25, 1994, more than six weeks before K & W filed its claim with the
    state appeal board and more than a year before the two-year statute of
    limitations on its tort claim expired. See Iowa Code § 669.13 (requiring tort
    claim against state to be filed within two years of its accrual). Therefore, the
    information in the Rust report must be imputed to K & W to determine
    whether it discovered its claim for inverse condemnation more than five
    years prior to filing this suit.
    The Rust report detailed how the highway construction project altered
    the flooding potential in the area of the plaintiff’s business. It stated the
    water levels in the diversion channel, which is close to the plaintiff’s
    20
    property, had been increased by the DOT project, an increase that in turn
    resulted in higher flood profiles. Of particular significance here, the study
    concluded the flood elevation had increased the most at Lincoln Street
    where the level was 1.9 feet higher than prior to the highway construction.
    (K & W’s property is located on Lincoln Street.)
    The importance of this information to the plaintiff’s discovery of its
    permanent injury is illustrated by a comparison of the contents of the Rust
    report to the takings claim made in the present lawsuit.          The factual
    assertions made in K & W’s petition in support of its inverse condemnation
    claim are derived from and substantiated by the Rust report. In addition,
    the plaintiff’s expert witness relied principally on the Rust report to support
    his conclusion that “K & W is faced with an increase in flood depth of 33%”
    and an increase in flood duration of greater than 33%.
    K & W seeks to minimize the Rust report conclusions, arguing the
    highway project was not completed when the report was published in 1994,
    and as a result, the plaintiff could not have known that future flooding
    would occur once the highway project was finished. But the Rust report
    assumed the completion of the project as designed and made projections of
    flood elevations on that basis. Consequently, the plaintiff could easily have
    discovered as early as January 1994 that the completion of the project
    would exacerbate rather than diminish the flooding potential on its
    property.
    In summary, had the plaintiff undertaken a reasonably diligent
    investigation preparatory to the filing of its March 1994 claim and its later
    decision not to file suit against the State, it would have uncovered the Rust
    report.     Therefore, the information contained in that report must be
    imputed to the plaintiff. K & W would have learned from a review of the
    Rust report that the 1993 flood was not an anomaly but was the result of a
    21
    permanent and significant increase in flood elevations caused by the DOT’s
    project. Because this information would have informed the plaintiff of the
    permanent nature of the injury to its property as well as its cause, the
    plaintiff is deemed to have discovered its inverse condemnation claim more
    than five years prior to filing this lawsuit. The district court did not err in
    granting summary judgment to the defendant on this basis. See Estate of
    Montag v. TH Agric. & Nutrition Co., 
    509 N.W.2d 469
    , 471 (Iowa 1993)
    (affirming summary judgment for defendant based on plaintiff’s inquiry
    notice of claim); Franzen v. Deere & Co., 
    377 N.W.2d 660
    , 661 (Iowa 1985)
    (same).
    V. Summary.
    The State has established as a matter of law that it is immune from
    tort liability for its design and construction of the highway project in
    question because the highways were constructed “in accordance with a
    generally recognized engineering . . . standard, criteri[on], or design theory
    in existence at the time of the construction.”       Iowa Code § 669.14(8).
    Therefore, the district court correctly granted summary judgment to the
    State on the plaintiff’s tort claims.
    When a property owner seeks recovery for the diminution in value of
    its property resulting from intermittent but inevitably recurring flooding
    caused by a government project, the landowner must file its action for
    inverse condemnation within five years of the date upon which it discovers
    the injury to its land and the cause of the injury. Here, the plaintiff was on
    inquiry notice of its claim after its property was first flooded in 1993.
    Because this lawsuit was filed more than five years later, its inverse
    condemnation claim is barred by the statute of limitations. Therefore, the
    district court correctly granted summary judgment to the State on the
    plaintiff’s takings claim.
    AFFIRMED.
