ARTICLE I. GENERAL PROVISIONS

SECTION 405.010: PURPOSE

This Chapter is adopted for the purpose of developing the land usage of the City of Clarkson Valley in an orderly manner, affording protection to property values, preserving the characteristics of the City, regulating and restricting the height, number of stories and size of buildings and other structures, the percentage of lot that may be occupied, the size of yards and other open spaces, the density of population; the locations, erection, construction, reconstruction, alteration and use of buildings, structures and land for trade, residence or other purposes, and promoting the health, safety, convenience, comfort, morals, prosperity and general welfare of its inhabitants. (CC 1990 §18.010)

SECTION 405.020: INTERPRETATION

The provisions of this Chapter constitute the minimum requirements for the promotion of the public health, safety, convenience, comfort, morals, prosperity and general welfare. It is not intended by this Chapter to interfere with, abrogate or annul any ordinances, rules, regulations, or permits heretofore or hereafter issued which are not in conflict with this Chapter, except as specifically provided herein; nor is it intended by this Chapter to interfere with, abrogate or annul any easements, covenants, or other agreements between parties with respect to the use of buildings or premises, except that if this Chapter imposes greater restrictions the provisions of this Chapter shall control. (CC 1990 §18.020)

SECTION 405.030: STANDARDS

In determining the usage of land and buildings, the restrictions thereon, any exceptions thereto, and otherwise in applying, interpreting, and enforcing this Chapter, the following standards shall be taken into consideration:

  1. In general, it shall be considered whether the proposed use will promote or endanger the public health, safety, convenience, comfort, morals, prosperity and general welfare of the inhabitants of the City of Clarkson Valley.
  2. The location, size, and characteristics of the City and its relationship to other communities in the Greater St. Louis Metropolitan Area shall be considered. In particular, account shall be taken of the relatively small size of the City and that it is predominantly a rural and residential area of farms and single-family homes located outside the commercial and industrial zones of the St. Louis metropolitan area.
  3. The present use of the land area of the City, and the preservation of existing property values, shall be considered. In particular, account shall be taken of the fact that the development of the City has been primarily through small subdivisions of private homes, under provisions for private maintenance of streets serving the subdivisions, and consideration shall be given to the effect of any proposed use of land and buildings upon investments made in homes and the assumption of liability for the private maintenance of streets.
  4. The safety of inhabitants of the City and, in particular, the dangers arising from the congestion of public or private streets shall be considered. Account shall be taken of the fact that sidewalks are seldom provided along the streets of the City and that streets are used for pedestrian as well as for vehicular traffic. Consideration shall be given to the limited number of thoroughfares maintained by public authority and to the necessity of avoiding congestion on the thoroughfares and the extensive use thereof by pedestrians.
  5. The providing of adequate police and fire protection to the City and to its inhabitants and other persons shall be considered and, in particular, the necessity of affording access at all times along public and private streets to the homes, institutions and other structures in the City. Account shall be taken of any disproportionate burden upon police and fire personnel, facilities, and equipment which will arise from any proposed use of land or buildings.
  6. The maintenance of a clean, quiet, orderly and pleasant community shall be considered and, in particular, the desirability of avoiding unnecessary or undue noise, noxious or unpleasant odors, fumes, and smoke, and unsightly grounds and buildings.
  7. The avoidance of overcrowding of land and undue concentration of population shall be considered and in particular, the maintenance of approximately uniform ratios of population to land area in the developed portions of the City.
  8. The furnishing of transportation, water, storm drainage, sewer disposal and public utility services shall be considered and, in particular, the effect upon such services, and the cost thereof, of any proposed use of land or buildings.
  9. The suitability of land within the City for any proposed use shall be considered and, in particular, its relationship to the surrounding area, its terrain and drainage, its size and proximity to public transportation, its effect upon pedestrian and vehicular traffic, the adequacy of access to the property, the effect thereof upon the value of other properties, and other factors pertaining thereto in light of the standards set forth above. (CC 1990 §18.030)
