This district is established to provide areas for single- and two-unit residential purposes. Persons and families residing in this district are entitled to protection from the encroachment of other types of uses not compatible with low to medium density residential areas. In relation to R-1 (low density residential) districts, the R-1-D district is intended to provide for high traffic flow; maintain a relatively quiet atmosphere; provide adequate open space; and discourage incompatible uses while serving as a buffer between single-unit residential districts and medium to high density residential districts. Adequate public water and municipal sanitary sewer service is required. Four (4) such districts are established with varying lot sizes and densities (R-1-15D, R-1-12D, R-1-8D, R-1-5D). (Ord. 2013-20)
