(A) The residential districts established in this chapter are designed to promote and protect the health, safety, morals, convenience, order, prosperity and other aspects of the general welfare.
(B) These general goals include, among others, the following more specific purposes:
(1) To provide sufficient space in appropriate locations for residential developments to meet adequately the housing needs of the present and expected future population for a variety of choices in site selections;
(2) To permit improved movement on the public ways and to utilize effectively existing public ways, and, as far as possible, to mitigate the effects of heavy traffic and more particularly, all through traffic, in residential areas;
(3) To protect residential areas against undue congestion, as far as possible, by regulating the density of population, the intensity of activity, the bulk of buildings in relation to the surrounding land and to one another and by providing for off-street parking spaces for automotive vehicles;
(4) To require the provision of open space in residential areas wherever practicable; and to encourage the provision of better standards of open space by permitting moderately larger bulk, higher density and greater intensity with better standards of open space in order to open up residential areas to light and air, to provide open areas for rest and recreation and to break the monotony of continuous building bulk and thereby to provide a desirable environment for urban living;
(5) To provide for access of light and air to windows and for privacy, as far as possible, by controls over the height of buildings and structures;
(6) To provide appropriate space for public and private educational, religious, recreational and similar facilities and public utilities which serve the needs of nearby residents and which do not create objectionable influences and to coordinate the intensity of residential land use with the appropriate community facilities;
(7) To provide a zoning framework conducive to freedom of architectural design in order to encourage the development of more attractive and economical building forms;
(8) To promote the most desirable use of land and direction of building development in accordance with a well considered land use plan, to promote stability of residential development, to protect the character of the district and its peculiar suitability for particular uses, to conserve the value of land and buildings and to protect the community’s tax revenues;
(9) To exclude from these districts all buildings and other structures and uses having commercial characteristics whether operated for profit or otherwise, except that conditional uses and home occupations specifically provided for in these regulations shall be considered as not having such characteristics if they otherwise conform to the provisions of this chapter.
