Rural Residential Zone
Rural Residential is intended to provide for very low density single-family detached residential units on larger lots ranging in size from two to eight net acres with maximum densities of 0.5 to 0.125 units per net acre for compatibility with the more rural areas of the City. Parcels located in flood plain areas, which are designated as Rural Residential Flood Plain (RRFP), are designated 0.125 units per acre (eight net acre lots). Other parcels range from two net acre lot size to four net acre lot size depending on slope. One primary dwelling is permitted on each legal lot. Single-family units may be attached to other single-family units provided each unit is located on a separate legal lot with approval of a PRD.
