At the time and place fixed for the public hearing, the corporate authorities shall meet and hear anyone desiring to be heard upon the subject of the proposed improvement. In case any person objects to the proposed improvement or any of the elements thereof, the corporate authorities shall adopt a new resolution abandoning the proposed scheme or adhering thereto, or changing, altering, or modifying the extent, nature, kind or character, without a further public hearing thereon, as it considers most desirable. Thereupon, if the proposed improvement is not abandoned, the committee on local improvements shall change or amend the plans, specifications and estimate of cost if it deems it necessary and prepare an ordinance authorizing and directing the improvement to be made.
