When any special assessment roll shall be reported by the Assessor to the Council, the same shall be filed in the office of the Clerk. Before confirming such assessment roll, the Council shall appoint a time and place when it will meet and review the same, and hear any objections thereto, and shall cause notice of such hearing and of the filing of such assessment roll to be published twice prior to such hearing in the official newspaper circulating in the City, the first publication to be at least one week prior to such hearing. Such hearing may be adjourned without further notice. Any person objecting to the assessment roll shall file his objections thereto in writing with the Clerk before the close of such hearing or within such further time as the Council may grant. After such hearing, the Council may confirm such special assessment roll as reported to it by the Assessor, or may correct the same as to any matter appearing therein in and confirm it as so corrected, or may refer it back to the Assessor for revision, or may annul it and direct a new roll to be made.
When a special assessment roll shall be confirmed, the Clerk shall endorse thereon the date of the confirmation. After such confirmation, the special assessment roll and all assessment therein shall be final and conclusive.
