Code § 5-424 (g)(3) (1994 Repl.)), '[w]here, by reason of exceptional narrowness, shallowness, or shape of a specific piece of property at the time of the original adoption of the regulations, or by reason of exceptional topographical conditions or other extraordinary or exceptional situation or condition of a specific piece of property, the strict application of any regulation adopted under D.C. Official Code §§ 6-641.01 to 6-651.02 would result in peculiar and exceptional practical difficulties to or exceptional and undue hardship upon the owner of the property, to authorize, upon an appeal relating to the property, a variance from the strict application so as to relieve the difficulties or hardship; provided, that the relief can be granted without substantial detriment to the public good and without substantially impairing the intent, purpose, and integrity of the zone plan as embodied in the Zoning Regulations and Map.'
