General Industrial (MG). The purpose of the MG district is to provide space for a broad range of light to heavy industrial uses, including manufacturing, transportation, warehousing, and distribution uses. It is applied where unsightliness, noise, odor, traffic, and the hazards associated with certain industrial uses will not impact residential, commercial, schools, other less intense use areas.

Light Industrial (ML). The purpose of the ML district is to provide space for light manufacturing, assembly, and distribution of manufactured products, R&D facilities, industrial supply, incidental warehousing, offices, parking, and supportive sales, which evidence no or very low nuisance characteristics. The ML district promotes high quality industrial and office park developments. The district applies to areas where nuisance characteristics of noise, odor, traffic generation, unsightliness, or hazardous materials manufacturing or storage are undesirable. Performance standards are applied to ensure minimum potential for adverse effects, that any unavoidable adverse effects are contained on site, and that the general objective of a high standard of property and use maintenance is met.

Special Industrial (MS). The purpose of the MS district is to provide space for lightest industrial operations, including limited manufacturing, assembly, distribution of manufactured products, R&D facilities, incidental industrial supply, incidental warehousing, offices, and supportive sales, as well as limited commercial uses along major arterials. The MS district promotes high quality industrial and office park developments. The district applies to areas where nuisance characteristics of noise, odor, traffic generation, unsightliness or hazardous materials storage or handling are avoided, and almost all uses will be conducted entirely within enclosed buildings.

Accessory structures and uses customarily incidental to any of the permitted uses listed in Table 18.40.020 when located on the same lot are permitted.

Accessory structures and uses customarily incidental to any of the conditional uses listed in Table 18.40.020 when located on the same lot are permitted only upon the granting of a conditional use permit pursuant to the provisions of Chapter 18.56.

No accessory building or structure shall be constructed on any lot prior to the time of construction of the principal building to which it is accessory.

Accessory structures and uses shall be located within the area of the lot allowed for principal structures and uses and shall conform to the required front, side and rear yard setbacks.

New or substantially modified industrial buildings shall be designed to limit warehouse, wholesale and distribution activities to a maximum of 75% of the gross floor area of the building with the remaining floor area used for assembly, manufacturing, research and development, sales, showrooms or office uses. This requirement can be waived by the decision maker if it can be found that the new or modified building will further the goals and policies of the Economic Development Element of the City's General Plan.

No use shall be permitted which creates odors, noise, vibration, heat, glare, or electrical disturbance detectable by the human senses without the aid of instruments, beyond the boundaries of the site. However, such uses may be approved by the decision maker, if they specifically find that the use will not result in substandard conditions or otherwise have a detrimental effect on the surrounding properties.

Site shall be maintained in good order at all times and consistent with project conditions of approval (if applicable). This shall include, but not be limited to, maintenance and repair of all on-site structures including building façade materials or paint, fencing/walls, signage, paved areas including sidewalks and driveways, and landscaping, as may be necessary to preserve a high-quality aesthetic for the area.
