c. Protect residential areas, as far as possible, against heavy and through traffic.
d. Protect residential areas against congestion, as far as possible, by regulating the density of population and the bulk of buildings in relation to the land around them and to one another, and by providing for off-street parking spaces; to require the provisions of open space in residential areas wherever practicable; and thereby to provide a more desirable environment for urban living in a metropolitan area.
e. Provide for access to light and air and for privacy, as far as possible, by controls over the spacing and height of buildings and other structures.
f. Provide appropriate space for those educational, religious, recreational, health, and similar facilities which serve the needs of the nearby residents, which generally perform their own activities more effectively in a residential environment, and which do not create objectionable influences.
g. Encourage the development of more attractive and economic building forms.
h. Promote the most desirable use of land and direction of building development in accord with the General 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 County's tax revenues.
i. Provide for the parking and storage of major recreational equipment within designated open spaces.
j. Provide for State authorized certification of licenses family care homes, foster homes, or group homes as a residential use of property.
