concurring.
I support the result reached by the majority and their conclusion that the word “substantially” is an important one that cannot be ignored in applying § 115-210 of the ordinance.27 I disagree, however, that the ultimate decision reached by the Board — to deny AT & T’s application for a special use exception — can be overturned solely on this basis.28 If the Board’s determination that AT & T had not demonstrated that “existing structures within a two-mile radius of the proposed location are not available for collocation” or that AT & T had not “substantiated” its need for a freestanding cell tower was proper and supported by substantial evidence on appeal to the Superior Court, then either determination, in my view, would provide an independent basis under §§ 115-209 and 115-194.2(D) of the ordinance to uphold the Board’s decision.29 But those determinations cannot be upheld because they were not supported by substantial evidence.30
The Board’s findings and decision on these related issues were premised in an important way on AT & T’s ability to improve the reliability of its service by placing an antenna on the water tower (sometimes described in the record as a “stand pipe”) owned by the Town of Bethany Beach. Although an AT & T employee testified at the Board’s hearing that the Town of Bethany Beach had twice rejected AT & T’s application to place an antenna on a water tower,31 a Town Council Member also testified that AT & T had not indicated any interest in using the water tower and that the Town remained open to allowing AT & T to use the tower as a site.32 The Board relied upon the *614Council Member’s testimony and premised its decision under § 115-194.2(D) to deny AT & T a special use permit on the availability of the water tower for use by AT & T. 33
On appeal to the Superior Court, AT & T presented indisputable evidence in the form of admissions by the Town itself that made clear that the Town would not permit AT & T to use the water tower.34 The Superior Court noted that the Board seemed to rely on a false premise in concluding that AT & T had not eliminated all possible locations for a facility in a two-mile radius.35 Nonetheless, the Superior Court also held that it could not consider that undisputed evidence on appeal because that evidence had not been before the Board.36
But, on appeal, a reviewing court must ensure that the “evidence is legally adequate to support the Board’s factual findings.” 37 Although the Superior Court correctly noted that it could not reweigh the evidence relied on by the Board, the Superior Court was permitted by 9 Del. C. § 6918(e) to “take evidence” as part of the statutory review process. Once it became apparent that the Board had premised a key legal finding on a clearly erroneous factual determination, the Superior Court had the power and, in these unique circumstances, which troubled the Superior Court itself,38 the duty to consider that undisputed evidence in order that a just determination of AT & T’s application would be made.39 However it came to be that the Town of Bethany Beach provided the Sussex County Board of Adjustment with the impression that the water tower was available to AT & T when it was not, the Town did so and caused the Board to rely upon a clearly erroneous fact, without which there is not substantial evidence to support the *615Board’s finding under § 115-194.2(D).40 Likewise, the Town’s own role in leading the Board to believe the water tower was available for use rendered the Board’s ruling arbitrary and capricious. To permit a ruling of a county adjustment board to stand when it is premised on a false finding of fact that a municipality within the county itself caused the board to make is Kafkaesque and the essence of arbitrary. By permitting the admission of additional evidence, 9 Del. C. § 6918(e) empowers the Superior Court to rectify situations like this and ensure that the Board’s findings are based on substantial evidence.
The Board’s reliance on this clearly erroneous fact finding also undermined its determination that placing an antenna on the water tower would provide adequate coverage and thus that AT & T failed to substantiate its need for a freestanding cell tower under § 115-194.2(D). But, as AT & T also points out, instead of addressing AT & T’s contention that it needed a freestanding tower to provide “reliable” coverage as an FCC licensee in the Bethany Beach area,41 the Board attributed to AT & T the notion that it was seeking “seamless” coverage, a word that the expert who testified for the Association used, not AT & T.42 After doing so, the Board then made a conclusory finding that implied if the permit was not granted, AT & T’s service, although not “seamless,” would be “adequate” without seriously weighing the record evidence that service was not reliable in several areas of the Town.43 In fairness to the Board, none of the parties before the Board seemed to present clear authority as to the applicable FCC standard AT & T was bound to meet as a licensee. But rather than consider the relevant reliability standard, even if that took an additional hearing to obtain input regarding what the FCC means by that term in practical application, the Board instead made a conclusory ruling based on different concepts from the license requirement of reliability.44 When the Board examines the application again, it must apply the relevant FCC standard in determining whether AT & T has demonstrated a sufficient need.
For these reasons, I believe that the majority’s conclusion as to the ultimate outcome is correct and concur in the result.
