The purpose of this zone shall be to maintain lots of sufficient size to insure that residential development not having access to public water supplies and dependent upon septic tank systems for sewage disposal will occur at sufficiently low density to insure a healthful environment. The R20 Residential- Agricultural Zone is established as a Zone to promote a compatible mixture of single-family residential and agricultural uses in areas outside town limits and where development is occurring. In this zone, a building or land shall be used only for one or more of the following purposes:
(A) Uses permitted.
(1) Any use permitted in the R6 Residential Zone;
(2) Agriculture, including the sale and processing of products produced on the premises;
(3) Cemeteries;
(4) Forestry;
(5) Mobile home dwellings, provided that only one mobile home shall be allowed per residential lot and in no case shall a mobile home be allowed to a lot occupied by any other principal building;
(6) Parks and historic sites;
(7) Plant nurseries;
(8) Public safety or public utility facilities, including public sewage disposal facilities; and
(9) Accessory buildings and uses customarily incident to any of the above permitted uses.
(B) Building height limit. No structure shall exceed 35 feet in height unless the depth of front and total width of side yards required herein shall be increased five feet for each story, or fraction thereof, of building height in excess of 35 feet.
(C) Building site area required for residences.
(1) The minimum building site area shall be one lot or parcel of land 20,000 square feet in area for each main building. Such parcel of land shall have average width of at least 100 feet at the front building line. When a lot or parcel of land has an area of less than the above required minimum area and width and was of record at the time of passage of this chapter, said lot may be occupied by only one family; provided, however, that the minimum side and front yard requirements set out in this section are conformed to regardless of pre-existing lot size.
(2) Multiple-family dwellings may be constructed, provided that the overall site provides a minimum of 20,000 square feet per development, plus 6,000 additional square feet for each family unit in the complex.
(D) Front yard required. There shall be a front yard having a depth of not less than 40 feet measured from the front of the street or road right-of-way to the front line of the main building. Provided, that when the geographic grade or contour of a lot is such that compliance with this section is impossible or will impose an undue hardship upon the property owner, the Board of Adjustment will establish a front yard depth suitable and practical for such lot. Where a lot fronts on two streets, the required front yard shall be provided on both streets.
(E) Side yard required. There shall be a side yard on each side of the main residential building having a width of not less than 20 feet. No accessory building shall be located nearer than ten feet to any interior lot line and shall not be located less than 40 feet from the street or road right-of-way of either street or road on corner lots.
(F) Residential development setbacks.
(1) All residential subdivisions or individually sold residential lots shall be located a minimum of 1,000 feet from any existing livestock or poultry facility using lagoon sewage disposal facilities. All residential subdivisions or individually sold residential lots shall be located a minimum of 500 feet from an existing livestock or poultry facility using waste disposal systems other than lagoons.
(2) This prohibition shall not apply to the construction of residential dwellings as a part of or located on a farm tract, when said residential lots are not to be separately deeded from the entire farm tract. These setbacks shall be measured from the point of the residential building nearest the facility to the edge of the facility building or lagoon that is nearest to the residential building.
(G) Livestock and poultry facility setbacks. Livestock or poultry facilities using lagoon sewage disposal facilities shall be located a minimum of 1,000 feet from any existing residential building located on property owned by a person or legal entity other than the owner of the livestock or poultry facility. Livestock and poultry facilities using waste disposal systems other than lagoons shall be located a minimum of 500 feet from any existing residential building located on property owned by a person or legal entity other than the owner of the livestock or poultry facility. These setbacks shall be measured from the point of the residential building nearest the facility to the edge of the facility building or lagoon that is nearest to the residential building.
(H) Prohibited uses and structures.
(1) The use of any property in this zone which would result in noise, odor, dust or chemical residues which would create or establish a nuisance or trespass. All livestock or poultry waste disposal systems of whatever type shall be operated according to guidelines established by the Agricultural Waste Management Committee, School of Agriculture and Life Sciences, North Carolina State University in cooperation with the Soil Conservation Service;
(2) The commercial processing of any livestock or poultry not grown on the premises;
(3) The raising of livestock or poultry in open pens or ranges. All livestock and poultry shall be grown in livestock or poultry facilities with waste disposal systems set out in guidelines established by the Agricultural Waste Management Committee (or its successor) of the School of Agriculture and Life Sciences, North Carolina State University, in cooperation with the Soil Conservation Service. Exceptions to this general rule are as follows:
(a) Poultry or livestock grown for personal use or consumption by residents of the tract in question;
(b) Livestock grazed on permanent pasture, not to exceed five head per acre of permanent pasture. Said pasture shall not be more than 100 feet from the property line; and
(c) Livestock temporarily grazed in corn or other grain fields, not to exceed ten head per acre. The temporarily fenced area shall be more than 100 feet from the property line and shall not be used for more than 60 days during the months of September and January.
(4) All other structures and uses not specifically permitted in the above list of permitted uses.
