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-8 corresponding to the minimum lot size 8000. The RS district is consistent with and implements the low density residential (LDR) land use designation of the general plan.
