(1) At the public hearing required by § 7-33-303, or at the time and place to which the hearing may be adjourned from time to time, all persons whose property may be affected by such improvement may appear in person or by attorney or by petition.
(2) After the public hearing and after considering any objections, the governing body by resolution may confirm, amend or rescind the original resolution as its final action.
(3) Such final action shall be the final determination of the issues presented, unless the owner of property to be benefited files, within ten (10) days thereafter, a petition for certiorari in the circuit court having jurisdiction to review the action of the governing body. Failure to take such steps within the ten (10) days constitutes a waiver of all objections.
