No permit shall be granted for a building or use if the design or construction of the same involves or is likely to involve exceptional risks of traffic congestion, public safety or hazard. If the design or construction of any building or use is so markedly incongruous with the character of the neighborhood as to materially affect the value of adjacent or nearby property, the Construction Code Official or Zoning Officer shall deny the permit and refer the applicant to the Board of Adjustment which shall act thereon.
