Chapter 19.56 — RESIDENTIAL AND AGRICULTURAL DISTRICTS

The purpose of this chapter is to establish residential use zoning districts in the City to provide for the housing needs of existing and future residents. This chapter describes allowed uses and development standards applicable to those districts in order to implement the City's General Plan residential land use categories.

(Ord. 2014-01 § 1)

Each residential Zoning District is described below, identifying the characteristic uses, intensity, and level of development intended for that district.

• A. Agriculture (A). Intended for those areas within the Sphere of Influence (SOI) that are in the Williamson Act, beyond the 20 year growth area, and those for which there are not available and adequate facilities and services within the horizon of the currently adopted General Plan. There are residential development options to allow septic/well and septic/ rural water developments at very low densities, consistent with the intended agricultural character. Residential development would require clustering with 70 and 80% open space, respectively. These designations can establish long-term agriculture and vineyard investment protection

• B. Rural Residential (RR). Designated for larger lot and fringe area development which allows gross average densities ranging from 0.60 to 2.28 dwelling units per acre. The lot size may be reduced from one acre to 21,780 square feet or 12,500 square feet with increases in open space from 10% to 20% and 25%, respectively. Both require development clustering to achieve allowable densities. Development may have well and septic systems and be part of a long-range planned annexation that addresses expanded City services. Isolated well and septic, surrounded by City-serviced property, is not allowed in new development.

• C. Standard Residential (SR). Allows for and encourages a full range and variety of singlefamily residential building forms, including detached and attached dwellings. Multiplefamily developments can be permitted subject to open space requirements that preserve the character and overall density of the district. A variety of lot sizes and setbacks are allowed in order to create interesting vibrant and unique new developments. An average density of 4.4 homes (dwelling units, DUs) per acre and an average lot size of 6,000 square feet allows for densities and lot sizes to vary within a development in the district. Buffer yard requirements (setbacks) and design standards (height, lot coverage, bulk, rooflines) ensure adequate separation and buffering from other, less intensive uses within the neighborhood.

• D. Village Residential (VR). Allows for multifamily dwellings up to three stories immediately around the historic downtown. The purpose of this district is to reinforce the urban village character of downtown and to provide living opportunities within walking distance to downtown. This district can be used for planned development, redevelopment, or infill. In this district, while single-family detached dwellings currently exist, future development is oriented toward multifamily, higher-density developments with an average density range of 12 homes (dwelling units, or DUs) per acre on shared lots. Individual home lots are not encouraged so as to allow more people to be within walking distance of goods and services.

(Ord. 2014-01 § 1)

Table 19.56.030-1 identifies allowed uses and corresponding permit requirements for the residential Zoning Districts subject to compliance with all other provisions of this title. Descriptions/definitions of the land uses can be found in Chapter 19.98 (Glossary).

Use regulations in the table are shown using symbols as follows: "P," uses allowed by right; "AUP," uses that require an Administrative Use Permit; "CUP," uses that require approval of a Conditional Use Permit; and "N," uses that are not permitted.

The following development standards are applicable to the Zoning Districts. These standards, along with other development standards (e.g., landscaping requirements, parking standards) in this title and Citywide Objective Design and Development Standards, are intended to assist property owners and project designers in understanding the City's minimum requirements and expectations for high quality development.
