(a) The commissioners court of a county by order may:
(1) describe the circumstances in which a special exception to the application of § 343.011 is available to a person and may grant the special exception in a specific case if the commissioners court finds that the specific case fits within the special exception, that the grant of the exception promotes justice, that the grant of the exception is not contrary to the public interest, and that the grant of the exception is consistent with the general purpose of § 343.011; and
(2) authorize in a specific case not covered by a special exception a variance from the terms of § 343.011 if the commissioners court makes the same findings in connection with the specific case that it makes in connection with a special exception under Subdivision (1) and finds that due to special conditions a literal enforcement of § 343.011 would result in an unnecessary hardship.
(b) The commissioners court shall keep a record of its proceedings under this section and must include in the record a showing of the reasons for each decision made under this section.
