Where because of practical difficulty, an applicant requests a variance of the lot area or other bulk requirements of this chapter, the Board of Appeals may grant a variance in the application of the provisions of this chapter in the specific case, provided that, as a condition to the grant of any such variance, the Board of Appeals shall make a specific finding that the application of the requirements of this chapter to the land in question creates such practical difficulty. In making this determination, the Zoning Board of Appeals shall take into consideration the benefit to the applicant of the variance if granted, as weighed against the detriment to the health, safety and public welfare of the neighborhood or community by such grant. In making such determination, the Board of Appeals shall consider:
(a) Whether an undesirable change will be produced in the character of the neighborhood or a detriment to nearby properties will be created by the granting of the area variance.
(b) Whether the benefit sought by the applicant can be achieved by some method, feasible for the applicant to pursue, other than an area variance.
(c) Whether the requested area variance is substantial.
(d) Whether the proposed variance will have an adverse effect or impact on the physical or environmental conditions in the neighborhood or district.
(e) Whether the alleged difficulty was self-created, which consideration shall be relevant to the decision of the Board of Appeals but shall not necessarily preclude the granting of such variance.
