(A) All ordinances described in this chapter remain in effect after adoption of the city code. They are of a permanent and continuing nature as authority for a specific act which has been performed. These ordinances are of two types, that generally distinguish them from other provisions of the city code, either:
(1) Their texts have no continuing reference value; or
(2) They are in the nature of a contract and of only occasional reference value.
(B) For these reasons, it appears justified to list and describe them here only to facilitate finding them in the event this becomes necessary.
