herein are otherwise specifically made, the notice may be given either by personal
delivery thereof to the person to be notified or by deposit in the United States mail
in a sealed envelope, postage prepaid, addressed to such person to be notified at
the person's last known business or residence address as the same appears in the public

by the certificate of any officer or employee of this city or by affidavit of any
person over the age of eighteen years, which shows service in conformity with this
Code or other provisions of law applicable to the subject matter concerned.
