9.10.010 Designation of residential zones.
As used in this title, the following land use designations shall be considered residential zones:
|
R-1 |
Low Density Residential |
|
R-2 |
Medium Density Residential |
|
R-3 |
High Density Residential |
(Ord. 806 § 1, 2007).
9.10.020 Intent and purpose.
The residential zones are established to provide for residential districts of varying densities for the purposes of family living permitted therein and including the necessary appurtenant and accessory facilities and uses associated with such living areas. The specific intent and purpose of each residential zone is identified below:
A. R-1 (Low Density Residential). Zone R-1 is established to provide for residential areas to be developed exclusively for one-family dwelling units, not to exceed 8.7 dwelling units per acre. In order to provide for the expansion of a single-family residential development into rural areas, provisions are made for the maintenance of limited agricultural pursuits. Additional uses, necessary and incidental to single-family development, are also permitted as shown in the Residential Land Use Matrix, Table 9.10A.
B. R-2 (Medium Density Residential). Established to provide for attached or detached two- and three-family dwellings not to exceed 15 dwelling units per acre.
C. R-3 (High Density Residential). Established to create multiple-family residential areas of four units or greater per parcel, not to exceed 30 dwelling units per acre. (Ord. 806 § 1, 2007).
9.10.030 Permitted land uses.
The following Residential Land Use Matrix, Table 9.10A, establishes the land uses that are permitted, conditionally permitted, permitted as accessory uses only, temporarily permitted, or strictly prohibited in the residential zones. Uses that are not listed in Table 9.10A shall be expressly prohibited. Uses not listed but similar to those permitted or conditionally permitted may be found to fall within the intent and purpose of this zone by the planning commission. The commission must find that the use(s) will not be more obnoxious or materially detrimental to the public welfare and must be comparable in nature and of the same class as the uses enumerated in this section.
