All plans, plats or replats of land, laid out in lots or plats, and the streets, alleys or other portions of the same, intended to be dedicated to public or private use, within the corporate limits of the city, shall first be submitted to the planning commission for its approval or rejection. Before such plan, plat or replat shall be entitled to be recorded in the office of the county clerk, they must be approved by the city commission after a report thereof has been submitted to the city commission by the planning commission. The disapproval of any plan, plat or replat by the city commission shall be deemed a refusal of the proposed dedication shown thereon.
B. The planning commission shall have the power and the duty to prepare and recommend to the city commission for adoption a comprehensive plan for the physical development of the city. In conducting its work, the planning commission may consider and investigate any subject matter tending to the development and betterment of such municipality and may make recommendations, as it may deem advisable, concerning the adoption thereof to the city commission. The planning commission may make surveys, studies, maps and plans in the conduct of its activities. In the preparation of the comprehensive plan, the planning commission may from time to time prepare and recommend to the city commission for adoption a part or parts thereof, which parts shall cover one or more major geographical divisions of the city or one or more major elements of the comprehensive plan. The planning commission may from time to time recommend extending, amending or changing any portion of the comprehensive plan.
C. In preparation of such comprehensive plan, the planning commission shall make careful and comprehensive surveys and studies of present conditions and future growth of the city, and with due regard to its relation to neighboring territory. The comprehensive 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, morals, order, convenience, prosperity and general welfare, as well as efficiency and economy in the process of development, including, among other things, adequate provision for light and air, the promotion of healthful and convenient distribution of population, the promotion of good civic design and arrangement, and wise and efficient expenditure of public funds.

The planning commission shall, with the help of appropriate municipal officials, check the proposed dedications or subdivisions of land and with other elements of the comprehensive plan for the city. The disapproval of any such plan, plat or replat by the city commission shall be deemed a refusal of the dedications shown thereon.

All such regulations shall be uniform for each class or kind of buildings throughout each district, but the regulations in one district may differ from those in other districts.
F. Zoning regulations shall be made in accordance with a comprehensive plan and designed to lessen congestion in the streets; to secure safety from fire, panic and other dangers; to promote health and the general welfare; to provide adequate light and air; to prevent overcrowding of land; to avoid undue concentration of population; to facilitate the adequate provisions of transportation, water, sewerage, schools, parks and other public requirements. Such regulations shall be made with reasonable consideration, among other things, as to the character of the district and its peculiar suitability for particular uses, with a view to conserving the value of buildings and encouraging the most appropriate use of land throughout the city.
