Except as otherwise provided in this section, any lot, use, sign, or structure lawfully existing on the effective date of this chapter or subsequent amendments thereto which does not comply with the standards of this chapter shall be defined as legal nonconforming and may be continued so long as it remains otherwise lawful. If the taking by eminent domain action of a portion of a lot reduces the lot dimensions or area below minimums prescribed in this chapter, the lot shall then be considered to be a legal nonconforming lot. All nonconformities shall be encouraged to convert to conformity wherever possible and shall be further subject to the requirements of Section 10.033, Continuation of Nonconforming Development, through 10.037, Completion of Nonconforming Development.
