40.220.020    Residential and Office Residential Districts (R, OR)

A.    Purpose.

1.    The residential (R-12, R-18, R-22, R-30 and R-43) districts are intended to provide for medium and higher density residential development based upon consistency with the comprehensive plan and compatibility with surrounding land uses. The following factors will be considered in the application of one (1) of these districts to a particular site:

a.    Properties designated urban medium density residential on the comprehensive plan should not exceed a density of R-22. Urban high density residential areas are appropriate for densities in the R-30 and R-43 districts.

b.    Proximity to major streets and the available capacity of these streets, adequacy of public water and sewer, vehicular and pedestrian traffic circulation in the area, proximity to commercial services and proximity to public open space and recreation opportunities. Development within these districts will be reviewed to ensure compatibility with adjacent uses including such considerations as privacy, noise, lighting and design.

2.    The office residential (OR-15, OR-18, OR-22, OR-30, OR-43) districts are intended to provide for residential and professional office development based upon consistency with the comprehensive plan and compatibility with adjacent land uses. It is intended that office developments within these districts will be of a higher standard in recognition of their residential setting. The following factors will be considered in the application of one (1) of these districts to a particular site:

a.    Proximity to major streets and the available capacity of these streets;

b.    Availability of public water and sewer;

c.    Vehicular and pedestrian traffic circulation in the area;

d.    Proximity to commercial services; and

e.    Proximity to public open space and recreation opportunities.

    Development within these districts will be reviewed to ensure compatibility with adjacent uses, including such considerations as privacy, noise, lighting and design.

(Amended: Ord. 2018-01-09; Ord. 2018-10-02; Ord. 2019-07-01; Ord. 2020-03-08)

6.    Minimum and Maximum Densities within the R-12, R-18, R-22, R-30, R-43 and All OR Districts. For uses other than mobile home parks, the review authority shall find that the established minimum densities will be achieved by all proposed land divisions or site plans. The applicant shall demonstrate that all required densities will be achieved. The review authority shall establish appropriate conditions to ensure density is achieved. Demonstration that the established minimum densities will be achieved shall be provided by the applicant as follows:

a.    Where single-family or duplex developments at densities below the minimum density are proposed for a portion of the project. The minimum density to be transferred to a higher density multifamily development elsewhere on the site may be approved; provided, that:

(1)    The application shall provide for a fully integrated design; or

(2)    The development shall provide for phasing in which each phase meets the minimum density; or

(3)    The development shall provide a site plan for preliminary approval of the remainder of the site, which shall be binding on the land owner and all future land owners. The binding document shall be a deed covenant, approved by the county. The covenant shall require that the approved site plan for the multifamily development will be constructed at the densities approved. Where any portion of the project exceeds either the density of the zoning district or twenty-one (21) units per acre, a market analysis shall be provided demonstrating that such a project is economically feasible in the county. Where a difference in density of over three (3) units per acre is proposed between developments in the site plan, the applicant shall provide deed covenants which notify the future owners of the lower density developments of the type and density of the adjoining development.

b.    For all other projects including multifamily and detached single-family structures the density of the project for each individual phase and at total project buildout shall meet the minimum density. In order to reduce impacts to and from adjacent properties, multifamily developments adjacent to industrial uses should include the following design standards:

(1)    Aspects of the development that will not be utilized for residential purposes should be located adjoining to the industrially zoned property where possible. Examples of such uses include parking, garages, access roads, required open space, carports and stormwater facilities.

(2)    If residential buildings must be placed adjoining to the industrially zoned property, single-story buildings should be used. If multiple-story structures are proposed building openings above the first floor should face away from the adjoining property in order to limit views and exposure to the adjacent use.

c.    Minimum density will be based on the developable area of the lot that remains after subtracting:

(1)    Land devoted to public or private roads or alleys, common parking areas and required sight distance triangles required for narrow lots under Section 40.260.155, public parks and trails, required landscaping and drainageways;

(2)    Land designated by covenant or public dedication to be permanently maintained in an undeveloped state because the land is identified as sensitive due to the presence of steep slopes, unstable land, historical or archaeological sites, wetlands and buffers, or other permanent physical development limitations as may be determined by the responsible official. All other lands shall be considered in the calculation of minimum density or floor area ratio including required setbacks, private recreation or common areas.

d.    Maximum density shall be calculated based upon the gross area of the site, excluding public right-of-way or street easements.

7.    Signs. Signs shall be permitted according to the provisions of Chapter 40.310.

8.    Off-Street Parking. Off-street parking shall be provided as required in Chapter 40.340 and Section 40.260.155 as applicable.

9.    Landscaping.
