[Ord. No. 10.200, 4-10-1978]
A. 
For the purpose of promoting health, safety, morals and the general welfare of the community, the Board of Aldermen of the City of Hallsville, pursuant to the power and authority granted by Sections 89.010 through 89.140 of the Revised Statutes of Missouri, may 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, the preservation of features of historical significance, and the location and use of buildings, structures and land for trade, industry, residence or other purposes.
B. 
For any or all of the foregoing purposes, the Board of Aldermen may divide the City into districts of such number, shape, and area as may be deemed best suited to carry out the purposes of this chapter; and within such districts may regulate and restrict the erection, construction, reconstruction, alteration or use of buildings, structures, or land. 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.
[Ord. No. 10.210, 4-10-1978]
Such 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 the overcrowding of land; to avoid undue concentration of population; to preserve features of historical significance; to facilitate the adequate provision of transportation, water, sewerage, schools, parks and other public requirements. Such regulations shall be made with reasonable consideration, among other things, to the character of the district and its peculiar suitability for particular uses, and with a view to conserving the values of buildings and encouraging the most appropriate use of land throughout the City of Hallsville.
[Ord. No. 10.220, 4-10-1978]
The Board of Aldermen shall provide for the manner in which the regulations and restrictions and the boundaries of the districts shall be determined, established and enforced, and from time to time amended, supplemented, or changed. No such regulation, restriction or boundaries shall become effective until after a public hearing in relation thereto, at which parties in interest and citizens shall have an opportunity to be heard. At least fifteen (15) days' notice of the time and place of such hearing shall be published in a newspaper having a general circulation in the City of Hallsville.
[Ord. No. 10.230, 4-10-1978]
Such regulations, restrictions and boundaries may from time to time be amended, supplemented, changed, modified or repealed. In case, however, of a protest against such change duly signed and acknowledged by the owners of 10% or more, either of the areas of the land (exclusive of streets and alleys) included in such proposed change or within an area determined by lines drawn parallel to and one hundred eighty-five (185) feet distant from the boundaries of the district proposed to be changed, such amendments shall not become effective except by the favorable vote of three-fourths (3/4) of all of the members of the Board of Aldermen. The provisions of Section 400.200 relative to public hearing and official notice shall apply equally to all changes or amendments.
