    [¶1] Sheridan County landowners Merlin and Lori Zowada petitioned the Board of
    County Commissioners1 to establish a private road to access their landlocked tract
    through property belonging to Mullinax Concrete Service Company. The Board’s first
    ruling in the case came before this Court in Mullinax Concrete Service Co. v. Zowada,
    
    2010 WY 146
    , 
    243 P.3d 181
    (Wyo. 2010) (Mullinax I).2 We remanded to the district
    court with a mandate to direct the commissioners to compare the relative merits of only
    two alternative routes, and to determine whether the greater cost of one of the routes was
    justified. After further proceedings, the Board again established the road on a route not
    favored by the Zowadas, who challenge the ruling in this appeal. We accepted
    certification from the district court, and we affirm.
    ISSUES
    [¶2] The Zowadas raise two issues relating to Mullinax’s construction of a stormwater
    collection facility on the route sought by the Zowadas and Mullinax’s evaluation of the
    costs of constructing and maintaining a road on the route selected by the Board. We
    restate those issues as follows:
    1. Should the Board have excluded certain facts as irrelevant because they relate
    to events that did not take place until after the Board received the viewers and appraisers3
    report and held its first contested case hearing in 2007?
    2. Were the Board’s findings supported by substantial evidence?
    FACTS
    [¶3] The Zowadas filed their petition on January 31, 2006. The Board appointed two
    sets of viewers and appraisers who considered six alternative routes for the private road,
    only two of which now remain in contention. They have come to be known as Route 1,
    championed by the Zowadas, and Route 6, the path the Board has now chosen twice. See
    1
    The governing statutes, Wyo. Stat. Ann. §§ 24-9-101 and 103 (LexisNexis 2005), have been amended
    several times since the Zowadas filed their petition, and jurisdiction over these actions now lies with the
    district courts rather than boards of county commissioners.
    2
    The parties returned to the Court a second time in Mullinax Concrete Service Co. v. Zowada, 
    2012 WY 55
    , 
    275 P.3d 474
    (Wyo. 2012) (Mullinax II). In that appeal, we determined that an amended statute for
    establishment of private roads did not apply retroactively to this case. 
    Id., ¶ 11,
    275 P.3d at 477.
    Mullinax II is not pertinent to the issues in this third appeal.
    3
    Pursuant to Wyo. Stat. Ann. § 24-9-101(h), three disinterested persons must be appointed to view the
    subject properties and proposed road locations, evaluate any damages to be suffered by the owner of the
    burdened property, and recommend to the decision maker the most reasonable and convenient route for
    the private road.
    1
    Mullinax I, ¶¶ 
    5-11, 243 P.3d at 183-85
    . The following is an aerial view of the general
    area and the original six proposed routes:
    Mullinex I, Appendix B.
    [¶4] As the map shows, Route 1 proceeds north to the Zowadas’ land from Fort
    McKenzie Road, Wyoming Highway 337. It crosses the narrow eastern end of
    Mullinax’s roughly triangular property along its approximately 168-foot boundary with
    property housing a warehouse owned by Big Horn Beverage, Incorporated.
    [¶5] Route 6 begins on Highway 337 approximately 1,500 feet west of Route 1,
    proceeds north on Industrial Road for roughly 1,200 feet until it crosses an unused
    railroad bed that parallels what was the northern border of Mullinax’s property, and then
    proceeds to the southeast for nearly another 1,200 feet to the western border of the
    Zowadas’ land. In other words, one driving west on Highway 337 heading for Route 6
    would pass Route 1, travel a significant distance west, then north, and then double back
    east to the Zowada property. Route 1 is, of course, considerably shorter than Route 6.
    [¶6] After the Board’s November 2007 contested case hearing, but before it issued its
    findings of fact and conclusions of law in December 2008, Mullinax advised that it had
    purchased land abutting what had been the northern boundary of its property and
    extending north of the railroad right-of-way. Mullinax I, ¶ 
    12, 243 P.3d at 185
    .
    Mullinax’s previous lack of a legal interest in that land had profoundly affected the
    evaluation of Route 6 by both sets of viewers and appraisers.
    [¶7] The first group of viewers and appraisers recognized that the Wyoming
    Department of Environmental Quality (DEQ) had mandated that Mullinax devise a plan
    2
    to keep sediment-laden stormwater from draining off its property to nearby Goose Creek,
    and that an engineering study commissioned by Mullinax concluded that the best solution
    required placing a structure at the northern end of Route 1. Because there was no equally
    well-engineered alternative for stormwater control, the first set of viewers and appraisers
    rejected Route 1. They ultimately selected a problematic variation of Route 6. Aware
    that no right-of-way then existed north of the Mullinax property line, and therefore
    concluding that a road paralleling the old rail line would require condemnation of
    another’s land, they suggested locating Route 6 on the bed of the old rail line.
    [¶8] The Board rejected the report because it concluded that the viewers and appraisers
    had failed to follow instructions, and it then appointed a new group of viewers and
    appraisers. Mullinax I, ¶ 
    9, 243 P.3d at 184
    . The new group rejected Route 6 because it
    would require obtaining an easement through the land that Mullinax purchased nearly six
    months later, and because at the time it could not be determined how long it would take
    to negotiate an easement or its cost. They chose Route 1, dismissing the contents of the
    design report relating to the stormwater containment pond with the conclusory statement
    that they felt “there are alternative locations for this type of facility which would serve as
    well.” 
    Id., ¶ 10,
    243 P.3d at 185.
    [¶9] In light of Mullinax’s intervening purchase of the land needed to construct the
    final leg of Route 6, the Board rejected the recommendation of the second group of
    viewers and appraisers. It concluded that although they had properly calculated the loss
    in value of Mullinax’s property attributable solely to the amount of land set aside for
    Route 1, Mullinax was also entitled to compensation for the loss of the additional land it
    would have to dedicate to stormwater containment if it could not place its sediment
    containment pond at the northern end of Route 1. It also noted that Mullinax should be
    compensated for the difference in construction costs between its planned method of
    remedying its stormwater problem and suggested alternatives that would permit the use
    of Route 1. 
    Id., ¶ 12,
    243 P.3d at 186-88.
    [¶10] Although the Board relied on admittedly imprecise evidence as to the costs of
    constructing the drainage control alternatives and of building a road on Route 6, it
    determined that the costs associated with each route were comparable. The Board also
    found that the value of resolving Mullinax’s stormwater problems as it planned to do
    offset any compensation which might be due for the Zowadas’ use of Route 6.
    Consequently, the Board declared that route the most reasonable and convenient to both
    parties, awarded no damages to Mullinax for Zowadas’ use of it, and required Zowadas to
    pay for the engineering and construction of the roadway between Industrial Road and the
    Zowada property. 
    Id. [¶11] Both
    parties filed petitions for review by the district court. The Zowadas claimed
    that the Board’s selection of Route 6 was not supported by substantial evidence, and
    Mullinax claimed that the Board applied an incorrect standard in determining the
    3
    damages and compensation due to it. The court agreed with the Zowadas because it
    concluded that the Board had not resolved whether the BNSF Railroad would permit
    users of the road to cross its right-of-way as required for Route 6, had not addressed the
    concerns of the first group of viewers and appraisers regarding the topographic
    challenges presented by that route, had ignored the comment in the second viewers’ and
    appraisers’ report that Mullinax’s sediment retention pond could be located in some area
    other than Route 1, and had not explained why it thought Route 6 was more reasonable
    and convenient than Route 1. The district court also agreed with Mullinax that the
    Board’s damage award was erroneous. 
    Id., ¶¶ 13-15,
    243 P.3d at 188-89.
    [¶12] The district court consequently reversed and remanded the case to the Board, and
    ordered it to reassemble the viewers and appraisers and to assess the damages for all
    possible road locations. Those damages were to be calculated as of the date of the
    viewing of the affected real properties, using an assessment of the values of those
    properties before and after burdening them with a private road. In addition, the court
    directed the Board to determine whether BNSF consented to the selected crossing,
    explain why the Board considered the selected route reasonable and convenient, and if
    building a road along any other route would cost more than Route 1, explain why those
    costs would be justified. 
    Id., ¶ 15,
    243 P.3d at 189. Mullinax then sought further review
    in this Court.
    [¶13] In many ways we agreed with the district court. We first observed that the Board
    was obligated to compare the costs and benefits of the two options to the parties’
    competing interests with greater specificity to determine which of the two contested
    routes was more reasonable and convenient. We also noted that the record was
    inadequate to allow it to do so. The anticipated cost of building the road on Route 6 was
    a mere “guestimate,” and not a formal contractor’s estimate. Moreover, the Board failed
    to address the viability and costs of suggested alternatives to Mullinax’s stormwater
    control plan. Finally, we concluded that Mullinax was entitled to damages for the
    decrease in value of the land it had purchased from its northern neighbor, and that this
    diminution in value was to be determined before and after being burdened by Route 6.
    
    Id., ¶¶ 18-22,
    243 P.3d at 191-92.
    [¶14] This Court determined that the case should be remanded to the Board, but we
    modified the instructions given by the district court in its order of remand. We concluded
    that the Board only needed to compare the relative merits of Routes 1 and 6. If the Board
    chose Route 6, it also had to justify the greater cost of that road and obtain a before and
    after appraisal of the extent to which the burden of the road would diminish the value of
    Mullinax’s land. 
    Id., ¶ 23,
    243 P.3d at 192. However, we also concluded that BNSF
    would allow users of the road to cross the BNSF right-of-way. 
    Id., ¶¶ 5,
    10, 243 P.3d at
    183
    , 85. Finally, we indicated that the Board could take additional evidence on remand,
    but found that it did not necessarily need to appoint viewers and appraisers. 
    Id., ¶ 23,
    243
    P.3d at 192.
    4
    [¶15] After remand, the Board took additional testimony and evidence on October 9,
    2012, and it issued Findings of Fact and Conclusions of Law on September 17, 2013. We
    will summarize those findings and conclusions here, but we will analyze the supporting
    evidence in detail in our discussion of Zowadas’ claims, and then only to the extent
    necessary to address those claims.
    [¶16] Among the first of the matters addressed by the Board was a significant
    development that occurred prior to the hearing on remand—Mullinax’s construction of its
    planned retention pond on the northern end of Route 1. At about the same time as the
    November 2007 contested case hearing, Mullinax received its second DEQ notice of
    violation in a year. Although the DEQ had been lenient in enforcing its stormwater and
    sediment control requirements out of consideration for the ongoing dispute between
    Mullinax and the Zowadas, its communications regarding remediation reflected an
    increasing sense of urgency. After the December 2008 release of a favorable decision by
    the Board, Mullinax assured the DEQ that it would immediately resolve the stormwater
    problem. It built the pond and accompanying drainage structures between December 31,
    2008, and January 13, 2009, at a cost of $23,799. The Board determined that Mullinax
    undertook that construction at its own risk.
    [¶17] The Board found that Mullinax placed the pond at the lowest point on its land, in
    an area that serves as a natural drainage terminus for the entire property, and which
    allows surface water to be easily directed to the pond. Sediment carried by the water
    settles in the pond, and the water is disposed of by absorption into the ground and
    evaporation. Mullinax removes the sediment which accumulates twice a year, trucking
    away approximately 120 tons—enough to fill eight fifteen-ton capacity dump trucks—
    each time. Since the pond was built, DEQ had inspected it twice and found that it
    complied with relevant surface water regulations.
    [¶18] Based on the testimony at the 2012 hearing, the Board found that the 2007 viewers
    and appraisers had wrongly concluded that Mullinax could use alternate locations and
    methods for handling surface water sediment that would be roughly equivalent to the
    existing pond in terms of cost and effectiveness. It then reviewed the eight alternative
    stormwater collection methods suggested by Zowadas’ witnesses. 4
    [¶19] The Board eliminated the second, fourth, fifth, and eighth options because they
    required Mullinax to pipe collected storm water across the Zowadas’ property, and the
    Zowadas were unwilling to grant Mullinax an easement for that purpose. The Board also
    4
    Although these witnesses were engineers, the options they presented cannot be called “designs” based
    on surveying and measurements done on site, taking into account how Mullinax’s business operated day
    to day and the underground and surface features of the property. Rather, the options were presented as
    mere “concepts” produced after briefly visiting the site, and the costs associated with them were quite
    rough and included no adjustments for the disruption of Mullinax’s business during their construction.
    5
    eliminated the seventh option, bridging the existing sedimentation pond, because cost
    estimates to do so ranged from $100,000 to over $220,000.
    [¶20] Of the remaining alternatives, the first option involved relocating the
    sedimentation pond to the southern edge of Mullinax’s property where it would be
    sandwiched lengthwise between the east entrance proposed for Route 1 and Mullinax’s
    existing truck scales. That option also required a large catch basin between Route 1 and
    Mullinax’s retail store, from which water would be channeled through pipes to the
    sedimentation pond. Building that option, including removal of portions of an eight to
    ten inch thick concrete pad, would cost Mullinax approximately $27,000 to $35,000 more
    than it cost to build the existing pond.5 There would also be costs resulting from placing
    the new pond over an area that contained utilities running from just south of the Mullinax
    property line to structures on the property.
    [¶21] The third option involved removing a substantially greater amount of concrete to
    build a fifty-foot-wide detention basin extending eighty feet to the north of the southern
    boundary of the Mullinax property. The basin was to be filled with rock and coarse
    gravel. Like the first option, this alternative would likely impinge on utilities running
    from the street to buildings on Mullinax property, and it could require relocating the truck
    scales to the west. The total cost of constructing this option would exceed the cost of the
    existing pond by $35,000 to $42,000.
    [¶22] The sixth option involved building a series of catch basins and drop inlets
    connected by perforated pipe which would empty into the existing pond. The pond
    would be filled with rock and coarse gravel, and the structures leading to it would
    allegedly slow the flow of stormwater, allowing it to partially infiltrate the ground and
    settle sediment from the water that reached the pond. Those structures were to be built
    south of Mullinax’s retail store and north of its scale and office facilities and its concrete
    batch plant. The cost of this option was estimated at $30,000 to $45,000 more than the
    cost of the existing pond.
    [¶23] The Board then evaluated the loss that Mullinax would suffer by virtue of
    selecting Route 1 or Route 6. It determined that Mullinax’s partial loss of the land
    underlying Route 1 should be valued at $4,500. To that it added the damages that would
    be suffered as a result of forcing Mullinax to use land outside Route 1 to manage
    stormwater, and the limitations that placed on use of the land. The Board calculated
    those damages by deducting what it cost Mullinax to build its sediment collection pond
    from what it would cost to construct the three options discussed above. Taking the least
    expensive option, it found that the additional cost to Mullinax would be $30,000 and that
    the total damages attributable to Route 1 would be $35,000.
    5
    The Board accounted for the risk taken by Mullinax in building that pond while litigation was still
    ongoing by deducting the cost of that facility from the total cost of pursuing each alternative option.
    6
    [¶24] In evaluating the damages that would result from selecting Route 6, the Board
    observed that shortly after its November 2007 hearing, Mullinax purchased the land that
    would contain Route 6 in an arm’s-length transaction for $20,000 per acre. It then
    calculated how much of that property would be required to build that route, and it
    determined that Mullinax would suffer $6,500 in damages from Zowadas’ use of Route 6.
    [¶25] In light of the greater damage to Mullinax’s property if Route 1 was selected, as
    well as Mullinax’s assertion that it would build the road necessary to use Route 6 at its
    own cost and for no more than $50,000, the Board selected Route 6 as the more
    reasonable and convenient choice. The Zowadas timely sought review of that decision,
    and we accepted direct certification from the district court under Wyoming Rule of
    Appellate Procedure 12.09(b).
    DISCUSSION
    Evidentiary Issues
    [¶26] Decisions concerning admission or rejection of evidence are reviewed for an
    abuse of discretion, and we will not interfere with the hearing officer or agency’s
    decision unless it is so unreasonable as to shock the conscience and appears to be so
    unfair and inequitable that a reasonable person could not tolerate it. Johnson v. State ex
    rel. Wyoming Workers’ Safety and Comp. Div., 
    2014 WY 33
    , ¶ 14, 
    321 P.3d 318
    , 322
    (Wyo. 2014). Administrative agency hearing officers are not bound by the technical
    rules of evidence that govern judicial proceedings. Watkins v. State ex rel. Wyoming
    Medical Comm’n, 
    2011 WY 49
    , ¶ 21, 
    250 P.3d 1082
    , 1089 (Wyo. 2011). Instead, they
    are to be guided by the standards articulated in Wyo. Stat. Ann. § 16-3-108(a)
    (LexisNexis 2013). Johnson, ¶ 
    16, 321 P.3d at 322
    . That statute requires the exclusion
    of evidence only if it is irrelevant, immaterial, or unduly repetitious. Wyo. Stat. Ann. §
    16-3-108(a).
    [¶27] Although the Wyoming Rules of Evidence do not apply to administrative
    proceedings, the definition of relevance contained in them is instructive. Evidence is
    relevant if it has “any tendency to make the existence of any fact that is of consequence
    to the determination of the action more probable or less probable than it would be without
    the evidence.” W.R.E. 401.
    [¶28] The Zowadas assert that the hearing officer abused his discretion in admitting
    evidence proving that the sediment retention pond at the northern end of Route 1 had
    been built after the November 2007 hearing. They also challenge the hearing officer’s
    admission of Nathan Mullinax’s sworn testimony that his company could and would
    build the road necessary for the use of Route 6 for $50,000.
    7
    [¶29] They first contend that such evidence was inadmissible because, in the first appeal
    relating to this case, they understood this Court to have remanded with instructions that
    the Board was not to consider events after the second set of viewers and appraisers
    viewed the Mullinax property. That reading of our earlier opinion is incorrect. As the
    Zowadas suggest, this Court did agree with the district court that the Board needed to
    assess the damages relating to the selection of Route 6 by considering evidence that
    compared the market value of the parcel purchased by Mullinax both with and without
    the burden of the proposed Route 6. We did not alter the district court’s direction that the
    appraisal of those market values relate to the worth of the property at roughly the time it
    was viewed. However, the Zowadas treat that “view” as the one which occurred in late
    2007 and, in doing so, ignore the district court’s direction to conduct an appraisal on
    remand comparing the before and after damages. Mullinax I, ¶¶ 15, 
    20, 243 P.3d at 189
    ,
    191. Neither this Court nor the district court restricted the Board to facts existing in
    2007, and to have done so would have been unrealistic at best.
    [¶30] The Zowadas also contend that the hearing officer should not have admitted the
    challenged evidence because it was irrelevant and, with respect to the evidence relating to
    the cost of road building on Route 6, because it was not credible. We can dispose of the
    second of those contentions summarily, because challenges to the credibility of testimony
    go to its weight, not to its admissibility. Easum v. Miller, 
    2004 WY 73
    , ¶ 33, 
    92 P.3d 794
    , 803 (Wyo. 2004); Robinson v. State, 
    11 P.3d 361
    , 374 (Wyo. 2000). As to the first
    contention, the record shows that evidence as to the construction and operation of the
    sediment retention pond and the costs of building a road on Route 6 was definitely
    relevant to the issues before the Board.
    [¶31] The evidence relating to the pond demonstrated that: (1) it was built to an
    engineer’s design specifications; (2) it was built for $23,799; (3) it worked as designed;
    (4) it captured approximately 240 tons of sediment each year; and (5) Mullinax could
    remove the sediment for disposal with little interruption of its business. The Zowadas did
    not produce evidence of comparable quality on those points with respect to its first, third,
    and sixth proposed options for sediment control.
    [¶32] The two engineers who testified for the Zowadas had not designed any alternatives
    to Mullinax’s pond. They had not surveyed or taken any measurements from which they
    could calculate what was required for a workable system. They did not know how much
    sediment ordinarily drained off the property, or the volume of traffic that ordinarily
    travelled through the scales and the area between the scales and Mullinax’s retail store,
    where Route 1 would have been located.
    [¶33] Consequently, they were uncertain what their “concepts” would cost and whether
    any hidden costs, such as dealing with utilities and sewer lines, might add to the price. It
    was equally unclear whether those alternatives would actually work; that is, whether they
    would accomplish the task as the existing pond does, or how costly they would be to
    8
    maintain, both from the standpoints of time and equipment expenses and disruption of
    Mullinax’s business.
    [¶34] The Board had to determine how the parties would be left if it chose one of
    Zowadas’ proposed options. The evidence challenged by the Zowadas was relevant
    because it showed that the already-built pond was more efficient and cost-effective than
    the three proposed alternatives.
    [¶35] Nathan Mullinax’s testimony regarding the cost of constructing the road on Route
    6 was also relevant for similar reasons. It made it more probable that choosing that route
    and allowing Mullinax continued use of its pond would more effectively, reasonably, and
    fairly balance the parties’ competing interests in cost and convenience.
    [¶36] That testimony showed that Mullinax had already paid an engineer to survey the
    route and design the road to be built on Route 6 at its own expense. Those expenses were
    to be levied upon the Zowadas in the 2008 Board decision. The design work showed that
    building a road along that route was feasible. To assure compliance with the clean air
    standards applicable to its operations, Mullinax preferred to assume the duty and cost of
    maintaining the road once it was built, rather than attempting to require Zowadas to pay
    part of those expenses as they had been required to do by the 2008 ruling.
    [¶37] Most importantly, the evidence revealed that Mullinax could and would build the
    road for its own cost, thereby providing a fixed price for the road which approximated the
    more speculative and less certain estimates of the cost of building an alternative drainage
    control system on Mullinax’s property. The Zowadas do not dispute that Mullinax has
    the experience and equipment necessary to build the road in question.6
    [¶38] To summarize, admission of the evidence challenged by the Zowadas did not
    violate any portion of this Court’s prior mandate in this case, and that evidence was
    relevant to issues that the Board had to resolve in order to rationally and justly decide the
    case. Consequently, we affirm the hearing officer’s rulings in these regards.
    Substantial Evidence
    [¶39] The Board was statutorily obligated to determine which route would be the most
    reasonable and convenient to both Mullinax and the Zowadas, giving full consideration to
    which would least damage Mullinax’s use of its lands. Wyo. Stat. Ann. §§ 24-9-101(h)
    6
    The Zowadas also argue that we should not consider Mullinax’s agreement to build the road for $50,000
    because it is a settlement offer under Wyoming Rule of Evidence 408. We disagree. Mullinax assumed
    responsibility to build and maintain the road, which is sensible in light of the fact that it will use the road
    for its operations. The Board based its decision on that assumption of responsibility, and if Mullinax fails
    to build the road as promised, another alternative will be chosen. This was not an effort to compromise a
    claim.

    and 103(a) (LexisNexis 2005). The latter necessarily involved weighing how the
    selection of Route 1 would affect the costs of Mullinax’s efforts to comply with DEQ
    requirements. The Zowadas now argue that the Boards’ resolution of these questions was
    not supported by substantial evidence.
    [¶40] We review an agency’s findings of fact by applying the substantial evidence
    standard required by Wyo. Stat. Ann. § 16-3-114(c)(ii)(E) (LexisNexis 2013). We have
    defined substantial evidence as relevant evidence that a reasonable mind might accept as
    adequate to support a conclusion, and have held that an agency’s factual findings are
    supported by substantial evidence if we can discern a rational premise for those findings
    from evidence in the record. In making that determination, we defer to the agency’s (or
    the hearing examiner’s) determination of witness credibility unless it is clearly contrary
    to the overwhelming weight of the evidence. Birch v. State ex rel. Wyoming Workers’
    Safety and Comp. Div., 
    2014 WY 31
    , ¶ 12, 
    319 P.3d 901
    , 906 (Wyo. 2014). This Court
    must be able to conclude that the agency decision was not contrary to the overwhelming
    weight of the evidence as a whole, considering the extent to which testimony from one
    party or another may be confused, uncertain, improbable, marked by incomplete or
    inaccurate knowledge, or otherwise unreliable.

    [¶41] As we noted above, the evidence introduced by Mullinax on key matters possessed
    the virtue of certainty. They indicated they would build the road on Route 6 for a
    maximum of $50,000, and the Board obviously found that statement to be credible, for it
    incorporated it as a fact in its final order. Mullinax also established the cost of building
    its sediment retention pond, that the pond worked, and that it was capable of capturing
    approximately 240 tons of sediment each year.
    [¶42] As also noted above, the evidence presented by Zowadas was not nearly so
    definite as to the cost and viability of the alternatives it proposed for controlling
    stormwater on Mullinax’s land. The Board could legitimately conclude that those
    alternatives were nothing more than vague concepts hatched after a few hours spent on
    the land without taking critical measurements, surveying to determine gradients, or
    researching the possibility that underground structures or business traffic on the site
    might adversely affect their cost and utility. In short, the expert witness who advanced
    those alternatives provided cost estimates that the Board could reasonably view as
    speculative.
    [¶43] As discussed earlier, the expert estimated that the cost of the first option would
    exceed the cost of Mullinax’s pond by $27,000 to $35,000. However, he was unaware
    that the new pond required by that option was located over a utility easement and sewage
    pipes servicing buildings on Mullinax’s property, and he did not account for any
    additional costs that would be incurred in dealing with those obstructions. Nor did he
    account for any costs associated with the fact that the new pond was to be situated
    between Mullinax’s truck scales and the southeast entrance to its property. He offered no
    10
    testimony how that location might adversely affect the ability to use the scales and
    entryway during or after the new pond’s construction.
    [¶44] Furthermore, Mullinax’s witnesses testified that the proposed catch basin to feed
    the new pond was not located where it could best capture stormwater. One testified that
    much additional concrete work would be required to redirect water to the catch basin, and
    that Mullinax would have to build those structures in the middle of the area with the
    highest vehicle traffic.
    [¶45] The Zowadas’ expert engineering witness estimated that the cost of the third
    option would exceed the cost of Mullinax’s pond by $35,000 to $42,000. That estimate
    failed to account for dealing with the sewer lines servicing Mullinax’s buildings, or for
    the costs associated with Mullinax’s simultaneous efforts to conduct its business and
    construct the large pond required by the third option in the area of its plant with the
    highest level of traffic. 7 Furthermore, that pond was four times the size of the one built
    by Mullinax, yet the Zowadas’ witness testified it would cost the same amount to build,
    which undoubtedly seemed as improbable to the Board as it does to us.
    [¶46] Mullinax’s experts even called the functionality of the pond in the third option into
    question themselves. They were concerned that even though it would be much larger
    than the existing pond, it was to be filled with rock and coarse gravel. The record is not
    clear on this point, but one assumes this would be necessary to permit heavy truck traffic
    to cross the pond. Whether the pond would function effectively when filled with solid
    rock was never addressed. On the other hand, two of Mullinax’s witnesses testified that
    the rock-filled pond would quickly fill with sediment, and one of the Zowadas’ experts—
    the “designer” of all the alternative options—agreed and noted that, once filled with
    sediment, the pond would no longer work. He suggested no method by which Mullinax
    could remove the sediment, and he gave no estimate of the costs of doing so or how often
    the pond would need to be cleaned out, if it could even be done.
    [¶47] The Zowadas’ expert estimated that the sixth option would exceed the cost of the
    existing pond by $30,000 to $45,000. It called for the construction of a series of small
    sediment-capturing structures, each of which would drain through similar downhill

    Approximately two months after the 2012 contested case hearing, the Board convened a public meeting
    to discuss and vote on the resolution of this case. Chief among the concerns expressed by the board
    members was the traffic issue raised by a traffic-flow analysis completed for Mullinax by an engineering
    firm in 2006 and Mullinax’s report of traffic flowing across its scale and through its southeast gate during
    five months in 2006 and 2007. The latter showed that, excluding the vehicles of employees and retail
    sales customers, 52 vehicles per day passed in and out of the scales and 94 per day passed in and out of
    the gate. The great majority of those vehicles on one of each trip carried a gross weight of between
    53,000 and 85,000 pounds. In the minds of the board members, that amount and type of traffic, when
    combined with the additional traffic that would patronize the Zowadas’ business presented an excessive
    safety risk that would be cured by the selection of Route 6.
    11
    structures to the existing pond, which was also to be filled with rock and gravel. As was
    the case with the first option, Mullinax’s witnesses testified that this alternative was not
    located so as to take advantage of the natural drainage on the site. And as with the third
    option, they concluded that the rock and gravel-filled pond would fill too quickly with
    sediment to remain workable. In short, the sixth option would use the existing pond and
    allow the use of Route 1, but the Board could rationally conclude that it would cost
    nearly twice again what the existing pond cost, be considerably less effective, have an
    extremely short useful life, and carry presumably much greater clean-out costs that could
    entail reexcavation of the pond on Route 1—if the sediment it contained could be
    removed at all.
    [¶48] After reviewing the record and considering the uncertainties inherent in the choice
    of Route 1, we conclude that the Board’s selection of Route 6 was not contrary to the
    overwhelming weight of the evidence. When the Zowadas’ evidence or lack thereof is
    compared to that presented by Mullinax, we conclude that the Board reasonably
    determined that Route 6 was the most reasonable, convenient, and cost-effective option
    for both parties.
    CONCLUSION
    [¶49] The evidence challenged by the Zowadas was properly admitted at the contested
    case hearing in 2012, and the Board’s decision to establish the private road along Route 6
    was supported by substantial evidence. We therefore affirm the Board’s Findings of Fact
    and Conclusions of Law.
