The Board of Zoning Appeals may authorize, upon application,
variances from this chapter. Such granting of a variance shall comply, as
nearly as possible, in every respect to the spirit, intent and purpose of
this chapter and sound floodplain management, it being the purpose of this
provision to authorize the granting of a variance only for reasons of unwarranted
hardship as distinguished from variations sought by the applicant for purposes
of convenience, profit or caprice.
