A. 
The purposes of this chapter are to:
1. 
Ensure that uses and activities are conducted in a manner that protects the public health and safety and do not produce adverse impacts on surrounding properties or the community at large.
2. 
Establish permissible limits and permit objective measurement of nuisances, hazards, and objectionable conditions;
3. 
Protect industry from arbitrary exclusion from areas of the City.
B. 
The standards of this chapter shall apply to all uses and properties existing in the City at the time of adoption of this Zoning Code. The standards established by this chapter are minimum requirements and shall not be construed to prevent the City Council, the Planning Commission, or the Director from imposing, as part of a project approval, specific conditions which may be more restrictive, in order to meet the intent of these regulations.
(Ord. 1722, 6/18/2024; Ord. 1733, 2/4/2025)
Measurements necessary for determining compliance with the performance standards of this chapter shall be taken at the property line of the establishment or use that is the source of a potentially objectionable condition, hazard, or nuisance.
(Ord. 1722, 6/18/2024; Ord. 1733, 2/4/2025)
Land or buildings shall be used or occupied in a manner that does not create any dangerous, injurious, or noxious fire, explosive, or other hazard that would adversely affect the surrounding area.
(Ord. 1722, 6/18/2024; Ord. 1733, 2/4/2025)

Applicants for proposed projects may be required to provide evidence that all applicable requirements relating to noise may be satisfied by the project prior to approval. Provisions contained in Chapter 8 of the 2035 General Plan shall apply in addition to other applicable sections of the Municipal Code that relate to noise and nuisance considerations. Standards deemed "normally acceptable" are established in in Table 8-5: Land Use Noise Compatibility Standards of the General Plan.
A. 
Standards.
1. 
Sources. Table 8-6: Noise Level Performance Standards for New Projects and Existing Non-Transportation Sources, of the General Plan, provides noise level performance standards that apply to the noise sources themselves for new projects and existing non-transportation sources.
2. 
Exposure. Table 8-7: Maximum Allowable Noise Exposure from Transportation Sources, of the General Plan, provides the maximum allowable noise exposure from transportation related (i.e., non-aircraft) noise sources.
B. 
Acoustic Study. An acoustic study shall be required for any proposed project which could create or be subject to noise exposure that exceed the levels established in General Plan Table 8-6: Noise Level Performance Standards for New Projects and Existing Non-Transportation Sources, and Table 8.7: Maximum Allowable Noise Exposure from Transportation Sources.
C. 
Noise Attenuation Measures. Any project subject to the acoustic study requirements of subsection B, Acoustic Study, may be required to incorporate noise attenuation measures deemed necessary to ensure compliance with established noise standards.
1. 
New noise sensitive uses (e.g., schools, hospitals, churches, and residences) shall incorporate noise attenuation measures to achieve and maintain an interior noise level within those established in Table 8-7: Maximum Allowable Noise Exposure from Transportation Sources, of the General Plan.
2. 
Noise attenuation measures identified in an acoustic study shall be incorporated into the project to reduce noise impacts to satisfactory levels.
3. 
Emphasis shall be placed upon site planning and project design measures. The use of noise barriers may be required only after all feasible design-related noise measures have been incorporated into the project.
(Ord. 1722, 6/18/2024; Ord. 1733, 2/4/2025)
No vibration shall be produced that is transmitted through the ground and is discernible without the aid of instruments by a reasonable person at the lot lines of the site. Machinery used for manufacturing and industrial processes, including oil and gas collection, processing, and distribution must be designed and housed to ensure that vibration will be reduced to a minimum amount discernible without the aid of instruments by a reasonable person at the lot lines of the site.
A. 
Development Near Railroads. A vibration study shall be required for any proposed development within 200 feet of a railroad track. Measures may be required to ensure that vibration impacts remain below acceptable levels.
B. 
Exemptions. Vibrations from temporary construction, demolition, and vehicles that enter and leave the subject parcel (e.g., construction equipment, trains, trucks, etc.) are exempt from this standard.
