(a) Within 30 days after such petition has been filed with the board of supervisors, it shall cause due notice to be given of a proposed hearing upon the practicability and feasibility of creating such water conservancy district. All interested parties shall have the right to attend such hearing and be heard. If it shall appear at the hearing that other lands should be included or that lands included in the petition should be excluded, the board of supervisors may permit such inclusion or exclusion, provided the land area involved still meets the requirements of Section 9-8-52.
(b) If it appears upon the hearing that it may be desirable to include within the proposed district territory outside of the area within which due notice of the hearing has been given, the hearing shall be adjourned and due notice of a further hearing shall be given throughout the entire area considered for inclusion in the district and a further hearing shall be held. After final hearing, if the board of supervisors determines upon the facts presented at the hearing and upon other available information that there is need in the interest of the public health, safety and welfare for such a district to function in the territory considered, it shall make and record the determination and shall define, by metes and bounds or by other satisfactory description, the boundaries of the district.
(c) If the board determines after the hearing that it is not feasible for such district to function in the territory considered, it shall make and record the determination and shall deny the petition.
