§ 35-310.05a. "R-3", "R-2", and "R-1" Single-Family Residential District.

(a)

Purpose. The "R-3", "R-2", and "R-1" (residential single-family) zoning districts are designed to provide options for developing dwelling units for specialized housing markets such as the affordable housing market, starter homes, and empty nester homes on small lots. These districts will provide areas for medium to high-density, single-family residential uses where adequate public facilities and services exist, prevent the overcrowding of land, and facilitate the adequate provision of transportation. The "R-3", "R-2", and "R-1" (residential single-family) zoning districts are designed to be in close proximity to schools, public parks, and open space serving the site. "R-3", "R-2", and "R-1" zoning districts are inappropriate for "enclave subdivisions" and are not permitted.

"R-3" subdivisions shall be limited to a maximum size of thirty (30) acres including lots, street right-of-way, easements and open space. "R-2", and "R-1" zoning requests shall be limited to a maximum size of two thousand nine hundred ninety-nine (2,999) square feet in order to prevent the oversaturation of small, compact subdivisions. This limitation shall not apply to city initiated zoning cases.

(b)
