SEC. 16-160.  PURPOSE AND INTENT.
   The following are descriptions of the purpose and intent of each one of the industrial zoning districts in the city. All permitted and conditionally permitted uses shall be consistent with the purpose and intent of the respective zone.
   (A)   C-M (Commercial Manufacturing Zone). The purpose of the C-M Zone is to provide a zone for selected commercial retail sales and services, light manufacturing, warehousing, distributing, storage, and wholesale activities that are conducted totally within a building and with development standards suitable for commercial and limited industrial districts. This zone district also allows for permanent and temporary emergency shelters and emergency shelters for families, supportive and transitional housing, and farmworker housing pursuant to statutory requirements, and provides an appropriate transition from residential areas to more intense industrial activities.
   (B)   BRP (Business and Research Park Zone). The purpose of the BRP Zone is to provide areas for a limited group of professional, administrative, and research, and limited manufacturing uses along with limited commercial activities intended to support such uses. Such uses shall be oriented toward major transportation elements such as freeways, airports, and harbors, and shall be developed to specific property and development design standards.
   (C)   M-L (Limited Manufacturing Zone). The purpose of the M-L Zone is to provide areas suitable for the development and protection of restricted manufacturing uses and activities involving a high level of performance and site development. Uses may include administrative, wholesaling, warehousing, and manufacturing activities, and scientific research offices and laboratories, including certain accessory facilities necessary to serve the employees of such uses located in the zone. The development and performance standards of this division will enhance views from major transportation routes and assure a high-quality environment compatible with surrounding and abutting residential zones. This zone district also allows for permanent and temporary emergency shelters and emergency shelters for families to provide housing pursuant to statutory requirements, and for adult businesses.
      (1)   Manufacturing uses shall be limited to the fabrication, assembly, compounding, processing, or packaging of materials in a processed form that do not, in their maintenance, assembly, or packaging, create obnoxious or offensive smoke, gas, odor, dust, sound, vibration, soot, or lighting.
      (2)   In order to avoid reduction of the city's industrial base and to protect industrial land and improvements from encroaching upon incompatible uses or uses more properly suited to other districts, residential and commercial uses, except as provided herein, are not permitted in the Limited Manufacturing Zone.
   (D)   M-1 (Light Manufacturing Zone). The purpose of the M-1 Zone is to provide areas for manufacturing and related service uses and activities where the principal activity occurs within a building, but also permits outdoor assembly, fabrication, public services, and storage that conform to the development and performance standards of this chapter, and provide areas suitable for adult businesses. Industrial uses in this zone shall be limited to those that conduct fabrication, assembly, or land processing of materials (including agricultural produce) primarily within a building. The development and performance standards of this chapter limit the creation of smoke, gas, odor, dust, sound, and vibration that might be detrimental to health, safety, and welfare to protect any adjoining uses. Wholesale and retail sales and services related to principal uses are permitted. Limited outdoor storage associated with a primary use may be permitted.
   (E)   M-2 (Heavy Manufacturing Zone). The purpose of the M-2 Zone is to provide areas for industrial uses that are primarily outdoor and/or within specialized structures that may involve general manufacturing, processing, and/or fabrication activities, including outdoor storage and manufacturing, that are specifically excluded from other industrial zones and which do not require highly restrictive performance and development standards in regard to adjoining uses.
