The residence districts set forth herein are established in order to protect public health, and promote public safety, convenience, comfort, morals, prosperity, and welfare. These general goals include, among others, the following specific purposes:
A. 
To protect residential areas against fire, explosion, noxious fumes, offensive noise, smoke, vibrations, dust, odors, heat, glare, and other objectionable factors.
B. 
To protect residential areas to the extent possible and appropriate in each area against unduly heavy motor vehicle traffic, especially through-traffic, and to alleviate congestion by promoting off-street parking.
C. 
To protect residential areas against undue congestion of public streets and other public facilities by controlling the density of population through regulation of the bulk of buildings.
D. 
To protect and promote the public health and comfort by providing for ample light and air to buildings and the windows thereof.
E. 
To promote public comfort and welfare by providing for usable open space on the same zoning lot with residential development.
F. 
To provide sufficient space in appropriate locations to meet the probable need for future residential expansion and to meet the need for necessary and desirable services in the vicinity of residences, which increase safety and amenity for residents and which do not exert objectionable influences.
G. 
To promote the best use and development of residential land in accordance with a comprehensive land use plan, to promote stability of residential development and protect the character and desirable development, and to protect the value of land and improvements and so strengthen the economic base of the community.
The O-1 Open Land District is composed of land being used for agricultural activities, floodplain, and other open land uses, located near the periphery of the jurisdictional boundary, which is not expected to develop in intensive urban uses within the near future. It is the intent of this district to allow open-type uses, to conserve the desirable characteristics of the land, and to protect the open area from the encroachment of scattered urban-type uses that may inhibit the urban development in accordance with the Comprehensive Plan.
