1. At the place, date and hour specified for the hearing in the notice or at any subsequent time to which the hearing may be adjourned, the board of county commissioners shall give full consideration to all protests which may have been filed and shall hear all persons desiring to be heard and shall thereafter adopt an ordinance either creating the district or determining that it shall not be created.
2. If the board of county commissioners determines at the hearing that the proponents of such proposed district have failed to show that creation of the district is required by public convenience and necessity or have failed to show that the creation of such district is economically sound and feasible, or both, it shall adopt an ordinance determining that it shall not be created.
3. Any ordinance creating a district may contain such changes as may be considered by the board of county commissioners to be equitable and necessary.
