Sec 122-15 Nonconforming Lots, Structures, And Uses
   A.   Within the zoning districts established by this chapter, there may exist lots, structures, and uses of land, or structures which were lawful prior to September 11, 1978, but which would be prohibited, regulated, or restricted under the terms of these zoning regulations or any future amendments thereto.
   B.   It is the intent of these zoning regulations to:
      1.   Consider such nonconforming uses to be incompatible with permitted uses in the zoning districts involved; and
      2.   Permit these nonconforming uses to continue until they are removed, but not to encourage their extended survival.
(Code 1991, § 12-214)
