The council may adopt the master plan as a whole by a single resolution or may by successive resolutions adopt successive parts of the plan (said parts corresponding with major geographical sections or divisions of the town or with functional subdivisions of the subject matter of the plan) and may adopt any amendment or extension thereof or addition thereto. Before the adoption of the plan or any such part, amendment, extension, or addition, the council shall hold at least one public hearing thereon, notice of the time and place of which shall be given by publication in accordance with section 1-22-2 of this code. The resolution shall refer expressly to the maps and descriptive and other matter intended by the council to form the whole or part of the plan. If the master plan affects any portion of unincorporated Summit County, an attested copy of the plan or part thereof shall be certified by the town clerk to the board of county commissioners of Summit County and, after the approval of such board, shall be filed with the Summit County clerk and recorder.
