The purpose of this Section is to regulate and limit the development and continued existence of uses, structures, and lots established prior to the effective date of this Ordinance that do not conform to the requirements of this Ordinance. Many nonconformities may continue, but the provisions of this Section are designed to curtail substantial investment in nonconformities and to bring about their eventual improvement or elimination in order to preserve the integrity of this Ordinance and the character of the Village and its extraterritorial jurisdiction. Any nonconforming use, structure, or lot which lawfully existed as of the effective date of this Ordinance and which remains nonconforming, and any use, structure, or lot which has become nonconforming as a result of the adoption of this Ordinance or any subsequent rezoning or amendment to the text of this Ordinance, may be continued or maintained only in accordance with the terms of this Section.
