The ordinance codified in this title shall be known and may be cited as "The Noise Control Ordinance" of the City of National City. 1 Section 12.02.040 Declaration of findings and policy. Whereas, excessive noise and vibration are a serious hazard to the public health and welfare and the quality of life; and Whereas, the people have a right to and should be ensured an environment free from noise and vibration that may jeopardize their health or welfare or degrade the quality of life. Now, therefore, it is the policy of the City to prevent noise and vibration that may jeopardize the health or welfare of its citizens or degrade the quality of life. Section 12.02.060 Criteria. As criteria for this chapter, Table I is a chart showing sound levels and their expected impact in terms of human response. Table II is a list of National Goals for Noise Reduction as set forth by the U.S. Environmental Protection Agency in their publication "Toward a National Strategy for Noise Control" April 1977. TABLE I SOUND LEVELS AND HUMAN RESPONSE Common Sounds Noise Level (dB) Effect Carrier deck Jet operation Air raid siren 140 Painfully loud Jet takeoff (200 feet) Thunderclap Discotheque Auto horn (3 feet) 130 120 Maximum vocal effort Pile drivers Chain saw (2 feet) 110 Garbage truck 767.10 Power lawn mower (4 feet) 100 Heavy truck (50 feet) City traffic 90 Very annoying Hearing damage (8 hrs) Alarm clock (2 feet) Hair dryer Vacuum cleaner 80 Annoying 2 Noisy restaurant Freeway traffic Man's voice 70 Telephone use difficult Air conditioning unit (20 feet) 60 Intrusive Light auto traffic (100 feet) 50 Quiet Living room Bedroom Quiet office 40 Library Soft whisper (15 feet) 30 Very quiet Broadcasting studio 20 10 Just audible 0 Hearing begins This decibel (dB) table compares some common sounds and shows how they rank in potential harm to hearing. Note that 70 dB is the point at which noise may begin to harm hearing, that 60 dB is the threshold of stress response and 45 dB disturbs sleep. To the ear, each 10 dB increase seems twice as loud. TABLE II A. To take all practical steps to eliminate hearing loss resulting from noise exposure; B. To reduce environmental noise exposure to an Ldn value of no more than 75 dB immediately; C. To reduce noise exposure levels to Ldn 65 dB by vigorous regulatory and planning actions; D.

Sections: 12.06.020 12.06.040 CHAPTER 12.06 EXTERIOR NOISE LIMITS Maximum permissible sound levels by receiving land use Corrections to exterior noise level limits Section 12.06.020 Maximum permissible sound levels by receiving land use. A. The noise standards presented in Table III of this chapter for various categories of land uses defined in Chapter 18.10 of the city land use code, shall, unless otherwise specifically indicated, apply to each property or portion of property substantially used for a particular type of land use reasonably similar to the land use types shown in Table III. Where two or more dissimilar land uses occur on a single property, the more restrictive noise limits shall apply. B. Additional land use classifications may be added by resolution of the planning commission to reflect both lower and higher existing ambient levels than those shown. 8 C. Where doubt exists when making identification of receiving land use, the planning commission may make an interpretation in the manner provided by Section 18.134.020 of the land use code. D. No person shall operate or cause to be operated any source of sound at any location within the city or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level to exceed the environmental noise level or nuisance noise level, or both, of the applicable limits given in Table III of this chapter at any point on or beyond the boundaries of the property on which the sound is produced. E. 1. Environmental noise shall be assessed by the A -weighted equivalent sound level (Leq) for any hour (Leq(h)). 2. Nuisance noise shall be assessed as an A -weighted sound level not to be exceeded at any time. Nuisance noise is not subject to hourly averaging as Leq(h). The sound level of an event may be assessed by sound level meters or recording devices, or by other objective methods. However, failure or inability to conduct measurements of the sound level shall not bar enforcement or abatement. 3. Sound levels by receiving land use shall be measured at the boundary of the property on which the sound is produced (generated) or at any point within the boundary of the property affected. 4. Fixed location public utility distribution or fixed transmission facilities, located on or adjacent to a property line shall be subject to noise level limits of this section measured at or beyond six feet from the boundary of the easement upon which the equipment is located. Section 12.06.040 Corrections to exterior noise level limits. A. If the noise is continuous as defined in Section 12.04.120, the Leq for any hour can be represented by any lesser time period within that hour. Noise measurements of a few minutes only will thus suffice to define the noise level. B. If the noise is intermittent as defined in Section 12.04.320, the Leq for any hour may be represented by a time period typical of the operating cycle. Measurement should be made of a representative number of noisy/quiet periods. A measurement period of not less than fifteen minutes is, however, strongly recommended when dealing with intermittent noise. C. In the event the alleged offensive noise contains a steady, audible sound such as a whine, screech or hum, or contains a repetitive impulsive noise such as hammering or riveting, or contains music or speech, the standard limits set forth in Table III shall be reduced by 5 dB. D. If the measured ambient level exceeds that permissible in Table III, the allowable noise level standard shall be the ambient noise level. The ambient level shall be measured when the alleged noise violation source is not operating. 9 TABLE III EXTERIOR ENVIRONMENTAL NOISE LIMITS1,2,3 1. Environmental Noise —shall be measured as Leq in any hour (Leq(h)). 2. Nuisance Noise —shall be measured as a decibel level not to be exceeded at any time. 3.

A. No person shall operate or cause to operate, any source of sound within a residential dwelling unit within a multifamily residential structure consisting of 2 or more dwelling units, or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which thereby causes the noise level at the adjacent interior boundary wall of an affected property to exceed the applicable noise level limits given in Table IV. 10 TABLE IV Type of Land Use Time Interval Maximum Allowable Interior Noise Level (dBA) No Time 1 min in 1 hour 5 or more min in 1 hour Multifamily Residential (Consisting of 2 or more units) 10 pm-7 am > 45 < = 40 < = 35 Multifamily Residential (Consisting of 2 or more units) 7 am-10 pm > 55 < = 50 < = 45 ( > greater than) (< = less than or equal to) B. If the ambient noise level inside the receiving dwelling unit exceeds that permissible within any of the noise limit categories in Table IV, the allowable noise exposure standard in that category shall be the measured ambient for a cumulative period of five minutes in any hour, ambient plus 5 dB(A) for one minute in any hour and shall not exceed the ambient plus 10 dB(A) at any time. Section 12.08.040 Correction for character of sound. In the event an alleged offensive noise event contains a steady, audible tone such as a whine, screech, or hum, or is an impulsive and repetitive noise such as hammering or riveting, or contains music or speech, the standard limits set forth in Table IV shall be reduced by 5 dB.

A. The planning commission is authorized to grant exceptions for any environmental noise provision of this title, subject to limitations as to area, noise levels, time limits, and other terms and conditions as the planning commission determines are appropriate to protect the public health, safety, and welfare from the noise emanating therefrom. This section shall in no way affect the duty to obtain any permit or license required by law for such activities, nor shall it apply to nuisance noises. B. Any person seeking an exception pursuant to this section shall file an application with the planning director. The application shall be submitted and processed in the same manner as conditional use permits as provided in Section 18.116.060 through 18.116.090. The application shall contain information that demonstrates that bringing the source of sound or activity for which the exception is sought into compliance with this title would constitute an unreasonable hardship on the applicant, on the community, or on other persons. The fee prescribed in the National City Fee Schedule shall accompany the application. A separate application shall be filed for each noise source; provided, however, that several mobile sources under common ownership, or several fixed sources on a single property may be combined into one application. Notice of an application for an exception shall be published according to Section 18.130.080 of the National City Land Use Code. Any individual who claims to be adversely affected by allowance of the exception may file a statement with the planning commission containing any information to support his claim. C. In determining whether to grant or deny the application, the planning commission shall balance the hardship on the applicant, the community, and other persons of not granting the exception against the adverse impact on the health, safety and welfare of persons affected, the adverse impact on property affected, and any other adverse impacts of granting the exception. Applicants for exceptions and persons contesting such exceptions may be required to submit such information as the planning commission may reasonably require, including sound level studies. In granting or denying an application, the planning commission shall keep on public file a copy of the decision and the reasons for denying or granting the exception. D. Exceptions shall be granted by notice to the applicant containing all necessary conditions including a time limit on the permitted activity. The exception shall not become effective until the applicant agrees to all conditions. Noncompliance with any condition of the 20 exception shall terminate the exception and subject the person holding it to those provisions of this title for which the exception was granted. E. An exception will not exceed three hundred sixty-five days from the date on which it was granted. Application for extension of time limits specified in exceptions or for modification of other substantial conditions shall be treated like applications for initial exceptions under subsection B of this section. F. The planning director will issue guidelines defining the procedures to be followed in applying for an exception and the criteria to be considered in deciding whether to grant the exception. G. Noise limit exceptions or allowances specifically provided for in the issuance of any exception granted under this Chapter or the city council approval of a temporary use permit pursuant to Chapter 15.60 for parades, civic functions or other special events, shall not be considered a noise disturbance. H. Estoppel. An application for exception shall have no effect until properly granted hereunder. Enforcement of violations shall be proper at any time prior to such granting. Section 12.16.040 Exceptions for time to comply. The owner of any commercial or industrial source of an environmental noise or sound source may apply to the planning commission for an exception in the length of time allotted to achieve compliance with the provisions of this title.

The planning director or designate is responsible for administration and enforcement of environmental noise, and making determinations that any given obtrusive noise condition falls within the definition of environmental noise disturbance, pursuant to Section 12.04.480A, as an environmental noise. Appendix A of Chapter 12.22 shall be used as an aid in such determinations. The planning director may make determinations pursuant to Section 18.104.030 for classifying noise sources not specifically mentioned in Appendix A. Sound level meters shall be used, when practicable or available, to measure the level of a noise disturbance. The duration of the noise event should be assessed, as applicable. Failure to do so shall not bar enforcement action to prosecute or abate violations, and the Planning Director may use other available evidence to justify such action. B. Responsibility. The planning director shall be responsible for investigation and enforcement of environmental noise disturbances. C. Guidelines. The planning director may, from time to time, promulgate additional guidelines for administration and enforcement of the provisions of this title pertaining to noise violations. D. Abatement.

Orders of abatement may be written or verbally administered. The order to abate an environmental noise disturbance may allow a reasonable time for abatement, not to exceed thirty (30) days, and nuisance noise disturbances may be ordered abated immediately. If the source of the noise is equipped with a volume control device, the violator shall be allowed to adjust the volume until the volume complies with lawful sound levels. Failure to comply within the time specified may thereafter be enforced criminally or civilly, or both, as a violation of this title. Abatement of the noise disturbance shall terminate further enforcement action regarding a particular environmental noise disturbance, unless the event is repeated. No complaint or further action shall be taken in the event that the cause of the violation has been removed, the condition abated or fully corrected within the time period specified by the planning director or designate. Section 12.18.060 Nuisance noise. A. Classification of Nuisance Noise. The chief of police or designate is responsible for administration and enforcement of any obtrusive noise condition that falls within the definition of nuisance noise disturbance defined under Section 12.04.480B or Chapter 12.10. Appendix A of Chapter 12.22 may be used as an aid in making such determinations. At the request of the chief of police, the planning director may make determinations as provided for under National City Land Use Code, Section 18.104.030 for classifying nuisance noise sources not specifically mentioned in Appendix A. B. Responsibility. The chief of police shall be responsible for investigation and enforcement of nuisance noise disturbances. C. Guidelines. The chief of police may, from time to time, promulgate guidelines for administration and enforcement of the provisions of this title pertaining to nuisance noise violations. Sound level meters shall be used, when practicable or available, to measure the level of the noise disturbance. The duration of the noise event should be assessed, as applicable. Failure to do so shall not bar enforcement action to prosecute or abate violations, provided there is other objective evidence available to justify such action. 22 D. Abatement Order. The officer responsible for enforcement of any provisions of this section shall first issue an order requiring abatement of a sound source alleged to be in violation of this Title 12. Orders of abatement may be written or verbally administered. The order to abate an environmental noise disturbance may allow a reasonable time for abatement, not to exceed thirty (30) days; nuisance noise disturbances may be ordered abated immediately. If the source of the noise is equipped with a volume control device, the violator shall be allowed to adjust the volume until the volume complies with lawful sound levels. Failure to comply within the time specified may thereafter be enforced criminally or civilly, or both, as a violation of this title. Section 12.18.080 Enforcement of noise disturbances that are both environmental and nuisance. A. Where investigation reveals that offending noise violates both the environmental noise regulations and the nuisance noise regulations, the offense shall be enforced as a nuisance noise violation unless the planning director, upon consultation by the chief of police, makes a specific finding that the environmental noise regulations more nearly apply, in which case the environmental noise regulations shall then apply. B. Nothing contained in this provision shall limit the city's ability to prosecute or abate noise violations as both environmental and nuisance noise. Section 12.18.090 Noise disturbance measurement procedure. Upon receipt of a complaint, the code enforcement officer shall investigate the complaint, measure the sound level using a sound level meter whenever practicable, and gather non -acoustic data to adequately define the noise problem. A. Non -acoustic data. Non -acoustic data shall consist of the following: the type of noise source; location of the source relative to the affected property; time period(s) and duration during which the noise source is considered to be a disturbance; and the date and time(s) of the noise measurement survey. B. Exterior Noise measurement procedure. Noise measurement procedure using a sound level meter defined in Section 12.04.640 shall use the "A" weighting scale and the "slow" meter response, except that the "fast" response shall be used for impulsive type sounds. Measurements shall be taken at any point on the receiving property with the microphone located at a height between four to five feet (4'-5') above the ground, and at least ten feet (10') from the source and any nearest reflective surface, if possible. The microphone shall be placed so as to take into account any relevant topography or any acoustical aberration or irregularity. C. Interior noise measurement procedure. If the complaint is related to interior noise, the "A" weighted scale, "slow" response (or "fast" if impulsive) shall be used, and measurements shall be taken within the affected dwelling unit at a point at least four feet (4') from the wall, ceiling or floor nearest the noise source, with the windows open or closed in normal seasonal configuration. D. Calibration. The sound level meter shall be calibrated both immediately before and after recording any noise data, using an acoustic calibrator. 23 Section 12.18.100 Violations: Additional remedies —Injunctions. As an additional remedy, the operation or maintenance of any device, instrument, vehicle or machinery which causes or creates sound levels or vibration exceeding the allowable limits specified in this title is declared to be a public nuisance, and shall be subject to abatement summarily by a restraining order or injunction issued by a court of competent jurisdiction, or through administrative means pursuant to Chapters 1.44 or 1.48. Additionally, no provision of this title shall be construed to impair any common law or statutory cause of action, or legal remedy therefrom, of any person or injury or damage arising from any violation of this title or from other law.
