  The board of supervisors to whom a petition filed pursuant to section 358.26 is addressed shall preside at the public hearing provided for in section 358.27 and shall continue the hearing with adjournments from day to day until completed without giving further notice of the hearing. A representative of the sanitary district board of trustees shall attend the public hearing and be available to answer questions regarding the proposed annexation. The board of supervisors may consider the property to be annexed, whether the property shall be described as provided in the petition or be otherwise described, and for the purpose of describing the property, may amend the petition by limiting or changing the property to be annexed as stated in the petition. The board of supervisors shall adjust the property to be annexed as needed to exclude land that has no reasonable likelihood of benefit from inclusion in the area to be annexed. The boundaries of the area to be annexed shall not be changed to incorporate property which is not included in the petition until the owner of the property is given notice of the proposed annexation as provided in section 358.27.

  All persons in the district and in the area to be annexed shall have an opportunity to be heard regarding the proposed annexation and make suggestions regarding the property to be annexed. The board of supervisors, after hearing the statements, evidence, and suggestions at the public hearing, shall enter an order determining the property to be annexed and directing that the question of annexation be submitted at an election to the registered voters residing within the district and within the area to be annexed. The order shall fix a date for the election which shall be held not more than sixty days after the date of the order.
