§42-31.
    Residential District Four (R4)
A.
Purpose. The purpose of Residential District Four (R4) is to foster orderly growth where the principal use of
land is low density residential. The intent of this district is to allow for limited residential development
consistent with the recommendations of the Comprehensive Plan. This general use district is typically meant
to be utilized in areas designated as Rural (RAA) or Conservation in the Comprehensive Plan. It is recognized
that this district is to be used in areas less suitable for dense or moderately dense development.
B.
Density and Dimensional Requirements. Each use allowed in this district shall, at a minimum, conform to the
following dimensional requirements (in the case of a nonresidential use the residential density dimensional
requirements shall not apply). In some cases a specific use may be required to meet the Supplemental
Requirements as set forth in §42-63 (Supplemental Requirements).

Residential density shall be calculated utilizing the entire acreage of a tract of land. Under this
scenario, residential density shall be determined based on the following formula:
Lot size x allowable units per acre = permitted dwelling units
The following example assumes a 5 acre tract with an allowable density of 0.20
units/acre:
5 acres x .20 units per acre = 1 permitted dwelling unit
The maximum residential density for portions of the tract with a slope of 60 percent or greater
(where such slope areas of the tract account for ten (10) percent or more of the tract) shall be one-
half (½) the eligible density.
Residential density shall be applied:
a.
On a lot existing at the time of the initial adoption of this Chapter, where there is not
adequate area to comply with the applicable standard residential density requirement; 
b.
To single-family residential uses; and
c.
To multifamily residential uses with fewer than five (5) units.
(2)
Accessory structures shall be located in side or rear yards and shall be setback a minimum of five (5)
feet from any property line.
