The commissioners shall give notice of the time and place of hearing, hear parties interested, and decide whether such enlargement is advisable. When they decide in favor of the annexation, they shall fix the bounds of the territory to be annexed. If such village is divided into wards, they shall determine in what ward or wards such annexed territory shall be placed, or, if necessary, create additional wards out of the same. They shall cause their report, containing a statement of the bounds fixed for such annexed territory and of the new and altered wards, if any, to be recorded in the office of the town clerk. (Amended 2017, No. 74, § 74.)
