§42-27.
  Residential District One (R1)
A.
Purpose. The purpose of Residential District One (R1) is to foster orderly growth where the principal use of
land is residential. The intent of this district is to allow for medium to high-density residential development
consistent with the recommendations of the Comprehensive Plan. This general use district is typically meant
to be utilized in areas designated as Urban (USA) in the Comprehensive Plan.
B.
Density and Dimensional Requirements. Each use allowed in this district shall, at a minimum, conform to the
following requirements (in the case of a nonresidential use the residential density 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).

(1)
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 4
units/acre:
5 acres x 4 units per acre = 20 permitted dwelling units
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.
(2)
Standard 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.
(3)
Intermediate residential density shall be available when individual dwellings would be served by
both: (1) a municipal water supply system and (2) a sewage disposal system (of the following types:
municipal, approved public, or approved community) which meet the requirements of applicable
local or state authorities having jurisdiction thereof.
(4)
Maximum residential density shall be available to applicants proposing five (5) or more dwellings in
any combination of the following unit types (duplexes, triplexes, quadraplexes and multifamily
dwellings with five (5) or more units and specifically excluding single-family units) where: 
a.
A total of at least five (5) units would be permitted by standard residential density, and
b.
Such dwellings are generally served by both: (1) a municipal water supply system and (2) a
sewage disposal system (of the following types: municipal, approved public, or approved
community) which meet the requirements of the local or State authorities. 
(5)
Accessory structures shall be located in side or rear yards and shall be setback a minimum of five (5)
feet from any property line.
  
(6)
Maximum height may be exceeded in multifamily developments as detailed in §42-63 (Supplemental
Requirements) SR 1.6. (Dwelling, Multifamily, Five (5) or More Units), provided such developments
do not exceed 50 feet in height.
