This chapter is adopted pursuant to Wyoming Statutes, 1977, sections 15-1-601 to 15-1-611. The purposes of this chapter are to encourage, classify, designate, regulate, restrict and segregate the highest and best location and use of buildings, structures and land for residence, recreation, commerce, trade, industry or other purposes in appropriate places; to regulate and limit the height, number of stories and size of buildings and other structures hereafter designed, erected or altered; to regulate and determine size of yards and other open spaces; and to regulate and limit the density of population; and for such purposes to divide the City into zones of such number, shape and area as may be deemed best suited to carry out the regulations contained in this chapter and provide for their enforcement.

Such regulations are necessary in order to encourage the most appropriate use of land; to conserve spaces for light and air and to prevent and fight fires; to prevent undue concentration of population; to lessen congestion of streets and highways; to conserve the environment by protection against land abuse and emission of noxious fumes, noise and contaminant particulates in the interest of public health; to facilitate adequate provisions for community utilities such as transportation, water, sewerage, schools, parks and other public requirements; and to promote the public health, safety, morals and general welfare, all in accordance with the master plan for the City.
