After the hearing, the Council shall forthwith proceed to make such modifications or changes as to it may seem equitable or just, or shall confirm the first proposed assessment, and upon reaching a final decision shall, by ordinance, fix the portions of the cost to be assessed against the benefited properties and against the owners thereof respectively, which ordinance shall incorporate by reference the assessment roll as approved by the Council. After the final enactment of such ordinance the amounts of the several assessments so listed, advertised and incorporated and not previously objected to shall be conclusively presumed to be just and equitable and not in excess of the special benefits accruing or to accrue by reason of the improvement to the specific property assessed.
