(1) 
Legislative Intent. The Suburban Residential (SR) and Single-Family Residential (R-1) districts are intended to facilitate development at targeted urban densities under the Comprehensive Plans, and provide for low-density, single-family residential development in areas designated by the Comprehensive Plan, depending on availability of infrastructure. Lower densities facilitate future subdivision at urban densities as infrastructure availability increases.
(a) 
Suburban Residential and Single-Family Residential Districts. These districts are further intended to:
(i) 
Facilitate coordinated and collaborative public infrastructure investment;
(ii) 
Prevent conversion of land to uses and densities that cannot be urbanized;
(iii) 
Require connection to public water and sewer systems;
(iv) 
Require full urban standards for developments within Urban Growth Areas;
(v) 
Locate low-density residential development, up to seven dwelling units per acre, in areas served by public water and sewer systems. In areas not served by public water or sewer, development on satellite utility systems will provide for an orderly, phased transition from rural to urban uses;
(vi) 
Maintain residential density permitted by zoning and limit density increases in the following areas:
(A) 
Areas where environmental constraints such as flooding exist, or where surface and groundwater quality make the land unsuitable for development to avoid potential health hazards, and
(B) 
Areas where public sewer and water will not be provided at the time of development, and the dwelling units have individual septic tanks.
(vii) 
Encourage residential cluster development prior to achieving maximum density, with a density of between four and seven dwelling units per acre on the developed portion sufficient to facilitate future urban development on adjacent sites, in areas with a public water supply and a community or regional public sewer system;
(b) 
Suburban Residential District. The purpose of the Suburban Residential (SR) district is further intended to provide areas for transitional uses as urban development expands, with a mixture of land uses and residential densities including small farms, scattered low-density residential development and clusters of higher-density residential development; and
(c) 
Single-Family Residential District. The purpose of the Single-Family Residential (R-1) district is further intended to protect single-family neighborhoods from encroachment by potentially incompatible non-residential land uses or impacts. Establish new residential neighborhoods and preserve existing residential neighborhoods for detached single-family dwellings free from other uses, except those which are compatible with and serve the residents of this district.
(2) 
Development Standards.
(a) 
New lots and structures and additions to structures subject to this Section shall comply with the standards for lots and building height, and setbacks in Tables 19.12.010-1 and 19.12.010-2, subject to Chapter 19.10 General Zoning Requirements and Section 19.35.020 Administrative Adjustments.
(b) 
Design of development proposals shall ensure that adequate setbacks, buffering of adjoining uses to allow appropriate infill development and sensitivity to physical features are achieved. Through review of the development, its surrounding designations and facilities, under the provisions of Chapter 19.34, particular emphasis shall be given to ensuring land divisions will facilitate future urban development, roads and other infrastructure and extension of utilities.
(c) 
Where the Reviewing Official authorizes development on systems other than area-wide public water and regional sewer, the development must provide for full urbanization of the property when urban utility services become available. An urban conversion plan may be required when development site does not meet a minimum average of four dwelling units per acre.
(d) 
Tracts created for drainage facilities, parks, open space, wetlands and buffers or utilities shall not be subject to minimum lot size requirements.

Legislative Intent.
(a) 
Two-Family Residential District (R-2). The R-2 district is intended to establish buildings that are typically single-family dwellings, duplexes and other compatible uses in areas served by local access streets and collectors. The purpose of the two-family residential district is to:
(i) 
Establish and preserve residential neighborhoods for land uses compatible with the intent of this district;
(ii) 
Locate residential development with a maximum density of 12 dwelling units per acre for duplexes, and a maximum density of 18 dwelling units per acre for multi-family dwellings under Chapter 19.14, in areas receiving a full range of public services including area-wide public water supply, regional public sewer, and police and fire protection;
(iii) 
Provide for an orderly, phased transition from rural to urban uses within Urban Growth Areas;
(iv) 
Facilitate coordinated and collaborative public infrastructure investment;
(v) 
Prevent conversion of land in the R-2 district to uses/densities that cannot be urbanized;
(vi) 
Require connection to public water and sewer systems where available; and
(vii) 
Require full urban standards for developments within Urban Growth Areas, meeting the County's minimum urban standards or the respective city's standards, whichever are higher.
(b) 
Multi-Family Residential District (R-3). The R-3 district contains a variety of attached or clustered multi-family dwellings in close proximity to neighborhood shopping facilities. The R-3 district is intended to:
(i) 
Provide for and protect medium and high-density residential districts by excluding activities not compatible with residential uses;
(ii) 
Locate high-density residential development, more than 12 dwelling units per acre, in areas receiving the full range of urban services;
(iii) 
Locate high-density residential development near neighborhood shopping facilities;
(iv) 
Locate high-density residential development so traffic generated by the development does not pass through lower-density residential areas; and
(v) 
Require full urban standards for developments within Urban Growth Areas, meeting the County's minimum urban standards or the respective city's standards, whichever are higher.
(2) 
Development Standards.
(a) 
New lots and structures and additions to structures subject to this Section shall comply with the standards for lots and building height, and setbacks in Tables 19.12.020-1 and 19.12.020-2, subject to Chapter 19.10 and Section 19.35.020.
