(2) order and hold a new hearing; and

(3) give new notices.

(d) If an improvement is abandoned, the new estimate, hearing, and notices are not required.

(e) A change in or abandonment of an improvement must be with the consent of the person who contracted with the municipality for the construction of the improvement.

(f) If an improvement is abandoned, a municipality shall adopt an ordinance that has the effect of canceling:
