Every ordinance, except the annual appropriation ordinances and an ordinance codifying
ordinances, shall be confined to a single subject, which shall be clearly expressed
in title. All ordinances shall be introduced in typewritten or printed form or a combination
of both. All ordinances which repeal or amend existing ordinances shall identify by
title the section or subsection to be repealed or amended. The enacting clause of
all ordinances shall be: "The City Council of Alexandria hereby ordains." Unless another
date is specified therein and except as otherwise provided in the charter, an ordinance
shall take effect on the date of its final passage. (Code 1963, Sec. 2-20)
