The RS district is applied to areas of the city appropriate for single-family residential uses in neighborhoods at densities of 2.5 to 10 units per net acre, subject to appropriate standards. The RS zoning districts generally apply to the single-family residential districts with development existing at the time of the adoption of this development code. The specific allowable density for each parcel is shown on the zoning map by a numerical suffix residential density designator RS-6 corresponding to the minimum lot size 6000. The RS district is consistent with and implements the low density residential (LDR) land use designation of the general plan.
