§ 156.303  RESIDENTIAL USE DISTRICTS.
   (A)   Districts and purpose.
      (1)   RC-1, Rural Conservation - 1 District. The purpose of this district is to provide types and intensity of development that primarily support the needs of the agricultural industry, while secondarily allowing for compatible rural residential development. This district shall be available for implementation on Cat Island and in the Guerin's Bridge Road area.
      (2)   RC-2, Rural Conservation - 2 District. The purpose of this district is to retain moderate population growth to reduce the demand for public services and facilities, while retaining the rural community character of these areas. This district shall be available for implementation in the Woodville area and in other areas between the Urban Growth Boundary and the Woodville area.
      (3)   RR, Rural Residential District.  The purpose of this district is to allow the development of large lot subdivisions in areas within the Urban Growth Boundary.
      (4)   CC, Community Conservation District. The purposes of this district are to preserve and protect the unique development characteristics of early residential settlements and to sustain the sense of community inherent therein.
      (5)   R-1, Low-Density Residential District. The purposes of the R-1, Low-Density Residential District, are to provide for low-density residential neighborhoods and to encourage the formation and continuation of a stable, healthy residential environment for detached single-family dwellings. The regulations that apply within this district are designed to discourage unwarranted and blighting encroachments by limiting commercial and prohibiting industrial uses; to disallow any other use that would subsequently interfere with the development or continuation of single-family usage; and to discourage any use that would generate traffic on minor streets other than that required to serve residences on these streets.
      (6)   R-2, Low-Density Residential District. The purposes of the R-2, Low-Density Residential District, are to provide for low-density residential neighborhoods and to encourage the formation and continuance of a stable, healthy residential environment for detached single-family dwellings. The regulations that apply within this district are designed to discourage unwarranted and blighting encroachments by prohibiting the commercial and industrial uses of the land; to disallow any other use that would substantially interfere with the development or continuation of single-family dwelling usage; and to discourage any use that would generate traffic on minor streets other than that required to serve residences on these streets.
      (7)   R-3, Medium-Density Residential District.  The purposes of the R-3, Medium-Density Residential District, are to provide for medium-density residential neighborhoods and to encourage the formation and continuation of a stable, healthy residential environment for single-family and duplex dwellings. The regulations that apply within this district are designed to discourage unwarranted and blighting encroachments by prohibiting the commercial and industrial use of land; to disallow any other use that would subsequently interfere with the development or continuation of single-family and duplex dwelling usage; and to discourage any use that would generate traffic on minor streets other than that required to serve residences on these streets.
      (8)   R-4, Medium-Density Residential District.  The purposes of the R-4, Medium Density District, are to provide for medium density residential neighborhoods; to encourage the formation and continuation of a stable, healthy residential environment for detached single-family dwellings; and to provide for smaller yards and spacing between dwelling units to allow for maximum development of land, without generating high traffic flows in areas of lower density development. The regulations that apply within this district are designed to discourage unwarranted and blighting encroachments by prohibiting commercial and industrial uses of land, and to disallow any other use that would substantially interfere with the development and continuation of high-density residential development.
      (9)   TH, Townhouse District.  The purpose of the TH, Townhouse District, is to provide for quality medium- and high-density residential developments. The regulations that apply within this district are designed to avoid congestion and interference of such development with lower-density residential development and other surrounding land uses; to discourage unwarranted and blighting encroachments by prohibiting the commercial and industrial uses of land; and to disallow any other use that would substantially interfere with the development and continuation of medium- and high-density attached dwelling unit developments.
      (10)   MF, Multi-Family Residential District. The purpose of the MF, Multi-Family Residential District, is to provide for quality medium- and high-density residential development. The regulations that apply within this district are designed to discourage unwarranted encroachment of commercial, industrial, or other uses capable of adversely affecting the residential character; and to discourage any use that would generate traffic on minor streets other than that required to serve residences on these streets.
   (B)   Uses.  Permitted, conditional, and special exception uses for all residential use districts shall be in accordance with the Use Table contained in this chapter.
   (C)   Lot, yard, height, and coverage requirements. Development standards for all residential use districts shall be in accordance with the following Development Standards Table except as provided below.
      (1)   Development standards for Single-Family Detached as shown in the Development Standards Table shall apply to nonresidential lots and buildings located within RC-1, RC-2, RR, CC, R-1, R-2, R-3, and R-4 Districts.
      (2)   Standards shall not apply to lots and principal buildings located in residential districts not intended to be used for dwellings, agricultural, or commercial uses. Examples include but are not limited to: open space, pump stations, and playgrounds.
