No judgment or decree nor any action of the Commission vacating a special assessment shall destroy or impair any lien of the city upon the premises assessed for such amount of the assessment as may have been equitably or lawfully charged and assessed thereon. Failure of any owner to receive any notice required to be sent under the provisions of the City Charter and this chapter shall not invalidate any special assessment or special assessment roll. In addition to the property tax lien created hereunder, any special assessment levied by the city shall constitute a debt owed to the city and may be enforced in the same manner as any contracted debt or in the same manner as provided by law for the collection of personal property taxes.
