This subchapter is intended to expedite the eventual elimination of existing uses or structures that are not in conformity with the provisions of subchapter 3 because their continued existence violates basic concepts of health, safety, and welfare as well as principles of good land use. However, in applying subchapter 3, no elimination of nonconforming uses or structures shall be effected so as to cause unreasonable interference with established property rights.
