Additions or changes to nonconforming land improvements such as parking lots, ponds, or other constructed features on land shall not be made unless the addition or improvement brings the land improvement or the development of which it is a part into greater conformity with this Ordinance. Where an improvement of this type is being made in association with enlargement of a nonconforming building, the application shall be considered under paragraph 14.4.1, Nonconforming Buildings or Structures, above.
