The zoning regulations and districts herein set forth are made in accordance with a comprehensive plan. They are designed to lessen congestion in the streets; to secure safety from fire, flood, panic and other dangers; to promote health and general welfare; to provide adequate light and air; to prevent the overcrowding of land; to avoid undue concentration of population; and to facilitate the adequate provision of transportation, water, sewage, schools, parks and other public requirements. They are made with reasonable consideration, among other things, to the character of area of each district and the peculiar suitability of such area for particular uses, and with a view to conserving the value of buildings and encouraging the most appropriate use of land throughout West Branch. For the purpose of promoting the health, safety, morals, or the general welfare of the community, the Council is hereby empowered to regulate and restrict the height, number of stories and size of buildings and other structures, the percentage of lot that may be occupied, the size of yards, courts and other open spaces, the density of population, and the location and use of buildings, structures, and land for trade, industry, residence, or other purposes. The authority of this chapter is based upon the right of the Council as empowered by the provisions of Chapter 414 of the Code of Iowa.
