Chapter 130.23 — INDUSTRIAL AND RESEARCH AND DEVELOPMENT ZONES

Sec. 130.23.010 - Zones Established; Applicability.

A.

This Chapter establishes several Industrial zones to provide for a full range of light and heavy manufacturing, including manufacturing, processing, distribution and storage. In addition, a Research and Development Zone is established to provide areas for high technology, non-polluting manufacturing plants, research and development facilities, corporate/industrial offices, and support service facilities in a rural or campus-like setting, such as a business park environment. [See General Plan Policy 2.2.1.2 (Land Use Designations).]

B.

This Chapter further provides regulations applicable to each industrial zone established in Section 130.12.020 (Zoning Maps and Zones) in Article 1 (Zoning Ordinance Applicability) of this Title. The Industrial zones are as follows:

1.

Industrial—Light (IL). The IL zone is applied to lands for manufacturing and associated retail or service activities, wholesaling, and other industrial uses, where the primary activity is conducted within a building or buildings, or in outdoor storage or activity areas. Conditional Use Permits shall be required for those uses which, by their nature, have the potential to produce or emit noise, odor, fumes, dust, smoke, vibrations, glare, heat, electrical interference or waste material beyond the confines of the property boundaries.

2.

Industrial—Heavy (IH). The IH zone is applied to areas which may also be suitable for more intensive industrial uses, including manufacturing, assembling, fabrication and processing, bulk handling, storage, warehousing and trucking. The uses associated with this district are likely to generate significant levels of truck traffic, noise, pollution, vibration, dust, fumes, odors, radiation, radioactivity, poisons, pesticides, herbicides, or other hazardous materials, fire or explosion hazards, or other undesirable conditions. A Conditional Use permit is required for uses having the potential to pose a safety hazard or produce particulate matter. Heavy industrial districts are unsuitable adjacent to residential districts and some commercial uses. Dwellings, care centers, and certain commercial uses are not allowed. Uses allowed within IL (Light Industrial) districts are allowed, provided that the uses are subordinate to and do not restrict heavy industrial uses in the zone. Activity at heavy industrial sites consists predominantly of trucks, rather than passenger vehicles, and the road system is built to support truck traffic. Provisions for pedestrians are not required.

3.

Research and Development (R&D). The R&D, Research and Development zone is intended to provide areas for the location of high technology, non-polluting manufacturing plants, research and development facilities, corporate and industrial offices, and support service facilities in a rural or campus-like setting, such as a business park environment.

Uses are allowed in the following zones subject to the requirements of this Title as designated in Table 130.23.020 (Industrial / R&D Zones Use Matrix) below in this Section:

A.

Research and Development Zones. Design standards for the Research and Development Zone are contained in the County's adopted Research and Development Zone Design Standards (Resolution 201-2015). The Design Review process, where applicable, shall determine whether the structure is in compliance with the adopted design standards.

CHAPTER 130.24. - RESIDENTIAL ZONES

Sec. 130.24.010 - Zones Established Applicability.

A.

This Chapter establishes residential zones as provided in the General Plan to accommodate a range of housing types, including single-family and multi-family housing for households of various income levels.

B.

This Chapter lists the uses that may be allowed within the residential zones established by Section 130.12.020 (Zoning Map and Zones) in Article 1 (Zoning Ordinance Applicability) of this Title, determines the type of planning permit/approval required for each use, and provides basic standards for site layout and building size.

C.

The manner in which the single-unit and multi-unit residential zones are applied are as follows:

1.

Multi-unit Residential (RM). The RM, Multi-unit Residential Zone identifies those lands which are most capable of supporting the highest density of development within the County, based on topography, infrastructure, and circulation availabilities and constraints, as well as proximity to employment centers, public facilities, recreation, and shopping. It is applied to regulate and promote the development of multi-unit dwellings, including apartments, condominiums, and townhouses, while ensuring compatibility with surrounding lower density residential neighborhoods. Detached or attached residential dwellings are allowed in accordance with the standards set forth in this Chapter, and providing the minimum density of at least 5 dwelling units per acre is met. This zone is utilized in Community Regions and Rural Centers to meet affordable housing goals identified in the Housing Element of the General Plan. Mobile home and manufactured home land lease development shall also be allowed within this zone (see General Plan Policy 2.2.1.2). This zone is applicable to lands designated as Multi-Family Residential (MFR) in the General Plan.

2.

Single-unit Residential (R). The Single-unit Residential Zone is used to promote and regulate the development of higher density, single-unit dwellings, and accessory structures and uses. Minimum lot size designations of R1 and R20K are applied to this zone based on surrounding use compatibility, and physical and infrastructural constraints. Said designations represent the minimum lot size of 6,000 and 20,000 square feet, respectively. This zone is applicable to lands designated as High Density Residential (HDR) in the General Plan.

3.

One-acre Residential (R1A). The R1A, One-acre Residential Zone, is used to create a more dispersed suburban residential character to an area by providing for and regulating medium density residential development at the highest range of one dwelling unit per acre. Accessory structures and uses and low-intensity commercial agricultural pursuits (crop lands, orchards, raising and grazing of domestic farm animals) are considered compatible with this zone. This zone is applicable to lands designated as Medium Density Residential (MDR) in the General Plan and may be applied to High Density Residential lands where infrastructure to serve higher densities is not yet available.

Two-acre Residential (R2A). The R2A, Two-acre Residential Zone, is utilized to create a more dispersed suburban residential character to an area by providing for and regulating medium density residential development at the mid-range of one dwelling unit per two acres. Accessory structures and uses and low-intensity commercial agricultural pursuits (crop lands, orchards, raising and grazing of domestic farm animals) are considered compatible with this zone. This zone is applicable to lands designated as Medium Density Residential (MDR) in the General Plan.

5.

Three-acre Residential (R3A). The R3A, Three-acre Residential Zone, is utilized to create a more dispersed residential character to an area by providing for and regulating the development of medium density residential development at the lowest range of one dwelling unit per three acres. Agricultural structures and low-intensity commercial agricultural pursuits (crop lands, orchards, raising and grazing of domestic farm animals) are considered compatible with this zone. This zone is applicable to lands designated as Medium Density Residential (MDR) in the General Plan.

6.

Residential Estate (RE). The RE, Residential Estate Zone is intended to preserve the rural character of an area by providing for and regulating the development of low density and rural residential development at a range of densities to include one dwelling unit per five acres and one dwelling per 10 acres. Minimum lot size designations of —5 and —10 are applied to this zone based on surrounding use compatibility, physical and infrastructural constraints, and General Plan use designation. Said designations represent the minimum number of acres allowed for each lot. Agricultural structures and uses are considered compatible with this zone.

Uses are allowed in the following zones subject to the requirements of this Title as designated in Table 130.24.020 (Residential Zone Use Matrix) below in this Section:
