The R-1 One-Family Residential District is composed of certain quiet, low-density residential areas of Richland Township, plus certain open areas where similar residential development appears likely to occur. The regulations for this district are designed to stabilize and protect the essential characteristics of the district; to protect the amenities of certain areas of Richland Township where the pattern has already been established with single-family developments on relatively large lots; to promote and encourage a suitable environment for family life; and to prohibit all activities of a commercial nature except certain home occupations. To these ends, development is limited to a relatively low concentration with relatively large lot sizes, and permitted uses are limited basically to single-family dwellings providing homes for the residents, plus certain additional uses such as schools, parks, churches and certain public facilities which serve the residents of the district.
