As the work on formulation of the master plan progresses, the commission may from time to time adopt and publish a part or parts thereof. The commission may from time to time amend, extend, or add to the master plan.

In the preparation of the master plan, the planning and zoning commission shall make careful and comprehensive surveys and studies of present conditions and future growth of the city, and with due regard to its relations to neighboring territory. The plan shall be made with the general purpose of guiding and accomplishing a coordinated, adjusted, and harmonious development of the city and its environs, which will, in accordance with present and future needs, best promote health, safety, order, convenience, prosperity, and general welfare, as well as efficiency and economy in the process of development. The plan shall include, among other things, adequate provision for traffic, the promotion of safety from fire and other dangers, adequate provision for light and air, the promotion of the healthful and convenient distribution of population, the promotion of good civic design and arrangement, wise and efficient expenditures of public funds, and adequate provision of public utilities and other public requirements.

In case of its disapproval, the planning and zoning commission shall communicate its reason for disapproval to the city council and thereupon by majority vote, it may overrule such disapproval.

The widening, narrowing, ornamentation, vacation, or change in the use of street and other public ways, public grounds, or other public improvements appearing on the adopted plan shall be subject to similar recommendations by the planning and zoning commission, and approved by the city council, and upon disapproval by the commission may be similarly overruled.
