Grammatical errors shall not invalidate any provision of this code. A transposition of words and clauses may be resorted to when a sentence is without meaning as it stands. Punctuation shall not control over the intent of the city council in the enactment of a provision. Words and phrases which do not conflict with the obvious purpose and intent of a provision nor in any way affect its scope and operation may be added when necessary to the proper interpretation of the provision. (1982 Code § 1.413)
