Chapter 17.08 — COMMERCIAL/OFFICE/INDUSTRIAL DISTRICTS

The following zoning districts are intended to provide regulations for the safe, efficient and creative design of the commercial, office and industrial areas within the city. The zoning districts are intended to be consistent with the land use designations that are described in the land use element of the Temecula general plan. In certain situations several zoning districts are established to implement the goals and objectives of the general plan.

The commercial/office/industrial zoning districts are intended to permit the range of industrial or commercial uses in areas where uses are consistent with the general plan. It is further intended to accomplish the following:

• A. Provide for appropriate commercial areas to provide the city with a sound retail and industrial base with employment opportunities for the community.

• B. To ensure compatibility of retail commercial and office uses with adjacent land uses and to minimize traffic congestion and overloading of the city's utility systems.

• C. To encourage and assure that new commercial and industrial development will be planned in a comprehensive manner with high standards of architecture, landscape and site design.

• (Ord. 95-16 § 2)

The purpose and intent of the zoning districts are described as follows:

• A. Neighborhood Commercial (NC). The neighborhood commercial designation includes smallerscale business activities which generally provide retail or convenience services for the local residents in the surrounding neighborhood. Typical uses include traditional small food markets (floor area less than twenty-five thousand square feet), drug stores, clothing stores, sporting goods, offices, hardware stores, child care and community facilities.

• B. Community Commercial (CC). The community commercial designation includes retail, professional office and service-oriented business activities which serve the entire community. Community commercial areas typically include some neighborhood commercial uses as well as larger retail uses including department stores, theaters, restaurants, professional offices, specialty retail stores and shopping centers.

• C. Highway/Tourist Commercial (HT). The highway commercial designation is intended to provide for those uses that are located adjacent to major transportation routes or within convenient access from freeway interchanges. Highway commercial development should be located near major arterials, and developed as clusters of commercial development rather than permitted to extend along the major streets. Typical uses may include tourist accommodations and lodging facilities, automobile service stations, restaurants, convenience shopping, and food stores, and gift shops.

• D. Service Commercial (SC). The service commercial designation is intended to provide for intensive commercial uses and selected light manufacturing uses that typically require extensive floor area. Typical uses include home improvement stores, discount retail stores, furniture stores, auto dealerships and auto service and repair. Warehousing and light manufacturing may be permitted as supporting uses for a business that is consistent with the service commercial designation.

• E. Professional Office (PO). The professional office designation includes primarily single-tenant or multitenant offices and may include supporting uses. The office developments are intended to include lowrise offices situated in a landscaped garden arrangement and may include mid-rise structures at appropriate locations. Typical uses include legal, design, engineering or medical offices, corporate and governmental offices, and community facilities. Limited supporting convenience retail and personal service (such as dry cleaners, barbers, shoe repair shop) commercial may be permitted to serve the needs of the on-site employees. A maximum of fifteen percent of the total square footage of the floor area shall be devoted to retail or personal service uses. Residential uses may be allowed on those PO properties that are subject to the affordable housing overlay.

g convenience retail and personal service (such as dry cleaners, barbers, shoe repair shop) commercial may be permitted to serve the needs of the on-site employees. A maximum of fifteen percent of the total square footage of the floor area shall be devoted to retail or personal service uses. Residential uses may be allowed on those PO properties that are subject to the affordable housing overlay.

• F. Business Park District (BP). It is the intent of the business park zoning designation to develop well designed business and employment centers that include attractive and distinctive architectural design, innovative site planning, and substantial landscaping and visual quality. Typical uses may include administrative offices, research and development laboratories, custom-made product manufacturing, processing, assembling, packaging, and fabrication of goods, such as jewelry, furniture, art objects, clothing, on-site wholesale of goods produced, and labor intensive manufacturing, assembly, and repair processes which do not involve frequent truck traffic. Retail uses are not permitted in this zoning district, except as supporting a principal business park use (limited to fifteen percent of the square footage of the development).

• G. Light Industrial District (LI). It is the intent of the light industrial zoning designation to promote the development of attractive comprehensively planned industrial uses that will help to provide the city with a sound and diverse industrial base. This district allows for a wide variety of industrial uses, including manufacturing, compounding of materials, processing, assembling, packaging, treatment or fabrication of materials, and products which require frequent truck activity or the transfer of heavy or bulky items. Wholesaling, storage and warehousing within enclosed building, storage and wholesale to retailers from the premises of finished goods and food products are also allowed. Also included in this zoning district are the following uses: warehousing, freight handling, shipping, truck services and terminals, storage and wholesaling from the premises of unrefined raw or semirefined products requiring further processing or manufacturing. Storage of raw or finished materials may occur outside providing there is adequate screening from adjoining land use areas. Standards are provided to protect adjoining uses from excessive noise, odor, smoke toxic materials, and other potentially objectionable impacts.

• H. Special Use Overlay Zone No. 1. It is the intent of the special use overlay zone No. 1 to designate areas that adult businesses may be considered provided that they meet the provisions of Chapter 5.09 of the Temecula Municipal Code. This area is generally away from residential uses and other sensitive uses and is primarily located within the commercial districts.

• (Ord. 95-16 § 2; Ord. 96-19 § 2(EE); Ord. 97-17 § 2(D); Ord. 98-18 § 5; Ord. 98-19 § 5; Ord. 18-09 § 6)

The land uses list in the following Table 17.08.030 shall be permitted in one or more of the commercial zoning districts as indicated in the columns corresponding to each commercial district. Where indicated with a letter "P," the use shall be a permitted use. Where indicated with a "-," the

use is prohibited within the zone. A letter "C" indicates the use shall be conditionally permitted subject to the approval of a conditional use permit.

The development standards listed below are the minimum standards for development with the respective zoning districts. It is intended that these standards will be met in addition to the commercial/office/industrial performance standards of Section 17.08.070 . Considerations for approval of development plans and for awarding floor area ratio bonuses will be based upon both the development standards and the degree of conformance with the performance standards. In the event of a conflict between the development standards and the performance standards, the director of planning shall determine which requirement best implements the intent of the development code. Separate development standards have been established for developments on a single lot and for those commercial shopping centers or industrial planned developments which include multiple structures on one or more lots.

The following Table 17.08.040A provides the development standards for the commercial/office and industrial districts for developments within planned shopping centers or industrial/business parks.

Notes:

1. Minimum required landscaped open area does not include necessary planting within the right-of-way.

2. All projects proposing an increase in FAR beyond the target FAR are required to comply with the criteria described in Section 17.08.050(A) .

(Ord. 08-07 § 8)

• A. Purpose. The purpose of this section is to provide for uniform performance standards and criteria for the design of commercial buildings within the city in accordance with the recognition that the quality and compatibility of building design directly impacts the health, safety and welfare of the residents of the community. Moreover, quality and compatible building design promotes and preserves the stability of the city through orderly growth and enhancement of a quality business environment. These purposes are further achieved through the following:

  1. The enhancement of the physical character of the community and quality of life through sound planning and coordinated development.

  2. The balancing of aesthetic design qualities with functional development.

  3. The preservation and enhancement of the physical character, integrity and quality of commercial/office/industrial areas.

  4. The enhancement and protection of property values and the adherence to the goals and policies of the general plan.

  5. The stimulation of improvements and maintenance of surrounding properties, thereby preventing and reversing the effects of urban blight.

• B. General Performance Standards. Developments in the commercial/office/industrial districts should be designed to provide variety and visual interest while still creating a unified overall

image. Performance standards to achieve this image include, but are not limited to, the following:

1. Use creative entry treatments with such features as canopies, awnings, cornices or atriums.

2. Use a variety of complementary colors and avoid the use of just one color and dark colors.

3. Use various window shapes and sizes.

4. Vary the building shapes by using curved or angled walls.

5. Separate buildings or accessory structures should be designed as an integral part of the primary building by using complementary materials, common architectural elements, and special landscape design techniques.

6. Use a consistent design theme throughout the project. Employ complementary or consistent details, shapes, materials and colors. In addition, consistent signage should be provided with complementary colors, lettering, placement and materials.

7. The bulk of the building should be divided to reduce the apparent scale and provide visual interest. Box-like designs should be avoided. This can be accomplished through the following:

   • a. Use variations in the building footprints and facades. Such variations should be proportional to the overall bulk of the buildings with variations being greater for large buildings.

==> picture [397 x 289] intentionally omitted <==

• b. Use a variety of shapes and forms including architectural projections such as roof overhangs, box windows, stairways, balconies, and cantilevers that create shadows on the buildings.

• c. Use contrasting vertical and horizontal elements that help to break the visual mass of the façade into smaller areas.

• d. Divide the bulk of the roof into smaller areas to reduce the apparent scale of the building and provide visual interest. The roof can be designed with varying heights and slopes to contrast with a flat roof.

  8. Where the character or scale is identifiable, new development should be designed to maintain that character and to be compatible with that scale. In areas where the character is not identifiable, new development should be designed to be complementary or consistent with desirable characteristics of the surrounding area in a way that contributes to the establishment of a positive character and scale for the area through the use of similar or complementary materials, colors, or building forms and design details.

  9. Development should be designed to minimize detrimental impacts on surrounding properties, including, but not limited to, visual, noise, air quality and other environmental impacts. Strategies for minimizing the impacts include protecting residential areas adjacent to commercial development through screening of circulation areas, loading areas and trash collection points or other areas that could potentially be disruptive to the residential character of the adjacent area.

• C. Commercial Development Performance Standards.

  1. Circulation.

     • a. Limit egress and ingress to commercial areas to common entrance points. Orient most of the vehicular access from side streets rather than directly from major arterial.

     • b. Separate vehicular and pedestrian circulation systems should be provided if possible. Pedestrian linkages between uses in the commercial areas should be provided. In shopping centers, provide separate pedestrian walkways from parking areas to the major commercial tenants. Whenever possible, parking lots should be designed to separate vehicular circulation routes from parking aisles.

  2. Architectural Design.

     • a. Large buildings should be designed in such a manner to avoid excessive mass and bulk. This can be accomplished by dividing the building form, varying the height of the roof structure and by creating offsets in the exterior walls.

     • b. The lower floors of commercial structures should not have blank walls. Windows, trellises, wall articulation, and entrances can provide relief along expansive wall surfaces.

     • c. Upper portions of multistory commercial structures can be stepped-back to reduce the bulk and mass of the buildings and to preserve pedestrian scale.

     • d. Long unarticulated walls should be avoided. Wall planes should not extend in a continuous direction for greater than fifty feet without an offset or enhanced architecture articulation.

  3. Site Planning and Design.

     • a. Pedestrian amenities in commercial developments should be provided to enhance the opportunities for pedestrian circulation and social activities. Strategies to achieve this high degree of pedestrian orientation and activity include, but are not limited to, the following:

• i. Orient the design of the buildings to the scale of pedestrian. First floor uses should be primarily retail commercial, restaurants, or public use areas. Windows and door entrances should be located on the ground floor to encourage pedestrian activity. Large expanses of uninterrupted wall surfaces should not be permitted.

     - ii. Provide covered or enclosed walkways between the buildings on the site. 
  
     - iii. Provide pedestrian plazas and sidewalks of sufficient width adjacent to buildings along with amenities such as special lighting, interesting paving materials, landscaping benches and other street furniture. 
  
  - b. Whenever possible, new structures should be clustered. This creates plazas or pedestrian malls instead of rows of commercial or "Strip commercial." Separate structures can be linked with arcades, trellis or clearly defined walkway. 
  
  - c. Minimize conflicts between pedestrian and vehicular traffic as much as possible by orienting pedestrian circulation areas parallel with the flow of traffic through the parking areas. 
  
  - d. Loading facilities shall not be located in front of structures without screening. These facilities are most appropriately located at the rear of the structures where screening can be minimal or not needed. 
  
  - e. Open space areas should be concentrated or clustered into larger more meaningful spaces at areas of significant activity, rather than dispersed into small areas of low impact or on the periphery of the site. 
  

  4. Compatibility. When a commercial structure is located adjacent to a residential neighborhood, additional setbacks from the residentially zoned area shall be required. Multistory buildings may be stepped back to preserve the scale of the adjacent low rise structures.

• D. Industrial Development Performance Standards.

  1. Circulation.

     • a. The circulation plan for an industrial development should clearly differentiate circulation plans for employees, visitors, truck traffic, loading areas and pedestrian circulation.

     • b. Facilities should be provided, when appropriate, for access to bus routes, bus stops.

     • c. Bicycle parking areas should be provided for employees.

     • d. Walkways and paths should be provided opportunities for walking or jogging for employees.

  2. Architectural Design.

     • a. Long unarticulated walls should be avoided. Wall planes should not extend in a continuous direction for greater than fifty feet without an offset.

==> picture [348 x 279] intentionally omitted <==

• b. Outstanding building and roof forms, and distinctive windows patterns.

• c. Blank wall elevations should be avoided on street frontages.

• d. Highly reflective surfaces are discouraged especially at the ground level.

• e. Wall materials should be selected that are resilient to damage from machinery.

• f. If rolling shutter doors are required, the doors should be mounted on the inside of the building to create an uncluttered appearance from the exterior.

3. Site Planning and Design.

• a. Placement of structures which creates opportunities for plazas, courts or gardens, lunch areas for employees with amenities such as outdoor seating and garden areas.

  • b. Design features which contribute to the design character of a project may include: ceremonial entrance drives, enhanced visitor parking areas, highlighted visitor entrance areas, decorative pedestrian plazas and walkways, focal landscape treatments, site sculptures, employee recreational facilities (exercise courses, jogging paths).

  • c. In order to provide security, lighting should be provided at a minimum illumination of one footcandle across parking areas and two footcandles at entrances. Lighting fixtures should be shielded to confine the spread of light to adjoining properties. The design of the lighting fixtures should be compatible with the architecture of the building.

  • d. Loading areas should generally not be located in the front of the building where it is difficult to adequately screen the loading areas from public view. These areas are most appropriately located in the rear or side of the property so that the loading docks and doors are not directly in the public view.

  • e. When walls or fences are necessary in the frontage of the property to conceal storage and mechanical equipment areas, walls should be architecturally treated on both sides and should be designed to complement and blend with the architectural design of the building.

• i. Long expanses of fencing or walls should be avoided unless offsets are provided, height variations, and combinations of materials are used to avoid monotony. Landscaping along the fences and at specific pockets should be provided.

• ii. Screening for outdoor storage should be a minimum of eight feet and a maximum of twelve feet high depending on the height of the material being screened. Exterior storage should be in the portions of the site least visible from public view.

==> picture [379 x 218] intentionally omitted <==

  - iii. Chain link fencing with wood or metal slatting between the links is acceptable for areas that are not visible from the street. 

  - iv. When screening is required, a combination of screening techniques may be used, including solid masonry walls, landscaped berms and landscaping. 

• f. Mechanical or other utility equipment shall be screened whether it is located on the roof, side of building or on the ground. The method of screening shall be architecturally integrated in terms of materials, color and form. Roof top equipment should be integrated into the design of the building.

4. Compatibility. Where industrial uses are adjacent to non-industrial uses, appropriate buffering techniques such as increased setbacks, screening, berms and landscaping must be provided to mitigate any negative effects of industrial operations.

==> picture [401 x 255] intentionally omitted <==

• E. Additional Performance Standards for Office Buildings in the Business Park (BP) and Light Industrial (LI) Zones. In order to encourage desirable characteristics of these zones, multiple free standing office buildings must be designed to be compatible with the surrounding scale. Performance standards to achieve this include, but are not limited to, the following:

  1. Larger single and multi-tenant office buildings are preferred;

  2. If multiple freestanding office buildings on a single site are proposed, they should be clustered around a courtyard or common area sufficient to retain a pedestrian scale and to prevent long "barrack-like" rows of buildings;

  3. The site should be designed with features that reinforce the visual and spatial relationship of each building and courtyard area, such as the use of decorative paving, landscaping and pedestrian amenities that complement the architectural design of the buildings;

  4. The landscaping and pedestrian scaled elements of the courtyard and building entrance areas, such as awnings or trellises, should be integrated into the elevation and the passageways should be safely lit.

• (Ord. 95-16 § 2; Ord. 96-19 § 2(KK); Ord. 01-14 § 1; Ord. 04-10 § 3)

Development projects and buildings should be designed to minimize detrimental impacts on surrounding properties, including, but not limited to, visual, noise, air quality and other environmental impacts. Strategies for minimizing the impacts include protecting residential areas adjacent to industrial development through screening of circulation areas, loading areas and trash collection points or other areas that could potentially be disruptive to the residential character of the adjacent area.

• A. Noise. Any existing or proposed uses which generate sounds that are or may be considered a nuisance or hazard to any adjacent property due to the intermittence, beat, frequency, or shrillness of the sounds, shall have the source of the noise muffled or otherwise controlled so that the noise is subdued to acceptable levels. Construction work is exempt from this requirement during the period a valid building permit is in force.

• B. Particulate Matter. Any existing or proposed use shall not discharge excessive particulate matter into the atmosphere for a period that exceeds three minutes in any one hour. The following standards establish maximum acceptable levels:

  1. Smoke. The density reading designated as Number 1 on the United States Bureau of Mines Ringelmann Chart is the maximum acceptable level.

  2. Dust, Dirt and Ash. Any level which can or may cause damage to the health of any individual, animal, or plant or physical soiling or discoloration of the surfaces of any structure or material which is located outside the property lines of the lot or parcel from which the particulate matter is emanating.

• C. Odors, Toxics and Noxious Matter. Any existing or proposed use which produces odors, toxic gases or noxious matter in such quantities as can or may be readily detectable at any point outside the property lines of the premises and when such emissions are or may become a public nuisance or hazard, the use shall be modified to prevent such releases.

• D. Vibration. Any existing or proposed use which generates vibrations that can or may be considered a nuisance or hazard on any adjacent property shall be cushioned or isolated to prevent generation of such vibrations.

• E. Glare. Any existing or proposed use that constitutes or may be considered a nuisance or hazard on any adjacent property due to emittance of excessive light or glare from mechanical or chemical processes or from reflective materials used or stored on the site shall be shielded or otherwise modified to prevent such emissions.

• F. Heat, Radiation and Electromagnetic Disturbances. Any existing or proposed use that can or may generate excessive heat, electrical disturbances or radioactive emissions that can or may be considered hazardous or a nuisance shall be shielded, contained or otherwise modified to prevent such generations, disturbances or emissions.

• (Ord. 95-16 § 2)
