5-28-103 Definitions.

For the purposes of this chapter, unless otherwise apparent from the context, certain words and phrases used in this chapter are defined as follows:

“A-weighted sound level” shall mean the standard A-weighted frequency response of a sound level meter, which de-emphasizes low and high frequency similar to the human ear for moderate sounds. The level so read is designated dB(a) or dBA.

“Ambient noise” shall mean all-encompassing noise associated with a given environment, being usually a composite of sounds from many sources near and far. For the purpose of this chapter, the ambient noise level is the level obtained when the noise level is averaged over a period of fifteen (15) minutes without the inclusion of noise from isolated identifiable sources, at the location and time of day near that at which a comparison is to be made.

“C-weighted sound level” shall mean the standard C-weighted frequency response of a sound level meter, which de-emphasizes high frequencies of sound in a manner similar to the human ear for relatively loud sounds. The level so read is designated dB(c) or dBC.

“Commercial area” shall mean any commercial area as defined in the General Plan and zoning provisions and designated by a “C” prefix in the zoning provisions and on the zoning map.

“Construction” shall mean any site preparation, assembly, erection, substantial repair, alteration, or similar action for or on public or private rights-of-way, structures, utilities, or similar property.

“Cumulative period” shall mean any additive period of time composed of individual time segments which may be continuous or interrupted.

“Decibel” shall mean a unit for measuring the amplitude of a sound, equal to twenty (20) times the logarithm to the base ten (10) of the ratio of the pressure of the sound measured to the reference pressure, which is twenty (20) micropascals.

“Emergency work or action” shall mean work or action made necessary to restore property to a safe condition after a public calamity, or work required to protect persons or property from imminent exposure to danger or damage, or work by public or private utilities to restore utility service.

“Fixed noise source” shall mean a stationary device which creates sounds while fixed or motionless, including, but not limited to, residential, agricultural, industrial, and commercial machinery and equipment, pumps, fans, compressors, air conditioners, and refrigeration equipment.

“Impulsive sound” shall mean sound of short duration, usually less than one (1) second, with an abrupt onset and rapid decay. Examples of sources of impulsive sound include explosions, drop forge impacts, and the discharge of firearms.

“Industrial area” shall mean any industrial area as defined by the General Plan and zoning provisions and designated by an “I” prefix in the zoning provisions and on the zoning map.

“Intrusive noise” shall mean that noise which intrudes over and above the existing ambient noise at a given location. The relative intrusiveness of a sound depends upon its amplitude, duration, frequency and time of occurrence, and tonal or informational content, as well as the prevailing ambient noise level.

“Licensed” shall mean the possession of a formal license or a permit issued by the appropriate jurisdictional authority or, where no permits or licenses are issued, the sanctioning of the activity by the jurisdiction as noted in public records.

“Mobile noise source” shall mean any noise source other than a fixed noise source.

“Motor vehicle” shall mean and include any and all self-propelled vehicles as defined in the Vehicle Code of the State of California, including all on-highway type motor vehicles subject to registration under said code and all off-highway type motor vehicles subject to identification under said code.

“Noise disturbance” shall mean any sound which:

(a) Endangers or injures the safety or health of human beings or animals; or

(b) Annoys or disturbs a reasonable person of normal sensitivities; or

(c) Endangers or injures personal or real property.

“Noise level” shall mean A-weighted sound pressure level in decibels obtained by using a sound level meter at slow response with a reference pressure of twenty (20) micropascals. The unit of measurement shall be designated as dBA.

“Noise sensitive zone” shall mean any area so designated for the purpose of ensuring exceptional quiet, for example, a hospital zone, nursing home, or family care home.

“Noise zone” shall mean any defined area or region of a generally consistent land use wherein the ambient noise levels are within a range of five (5) dB.

“Person” shall mean a person, firm, association, partnership, joint venture, corporation, or any entity, public or private in nature.

“Public right-of-way” shall mean any street, avenue, boulevard, highway, sidewalk, alley, or similar place which is owned or controlled by a governmental entity.

“Public space” shall mean any real property, or structure thereon, which is owned or controlled by a governmental entity.

“Pure tone” shall mean any sound which can be judged as audible by the Noise Control Officer as a single pitch or a set of single pitches.

If it is determined by the responding agency that a sound level in excess of the levels prescribed by this chapter exists, the following procedures shall be followed:

(a) A written warning shall be issued by the Noise Control Officer or his agent to the person responsible for the event causing the disturbance.

(b) If the disturbance persists for more than fifteen (15) minutes following the notice, or recurs within an eight (8) hour period, then the person responsible for the event causing the disturbance shall be guilty of a violation of this chapter. Any such violation shall be an infraction.

(1231-CS, Amended, 04/13/2017; 1207-CS, Rep&ReEn, 05/28/2015. Formerly 9-2-304)

5-28-106 Factors of determination.

The factors which will be considered in determining whether a violation of the provisions of this chapter exists shall include, but not be limited to, the following:

(1231-CS, Amended, 04/13/2017; 1207-CS, Rep&ReEn, 05/28/2015. Formerly 9-2-305)

5-28-107 Noise measurement procedure.

Upon the receipt of a complaint from a citizen, the Noise Control Officer or his agent shall investigate the complaint. For any short-term source, the investigation may consist of a determination that the noise or vibration causes discomfort or annoyance to a reasonable person of normal sensitiveness as determined by the Noise Control Officer. For any long-term source, the investigation shall consist of a measurement taken with a sound level meter and the gathering of data to adequately define the noise problem and shall include the following:

(a) Nonacoustic data.

(1) The type of the noise source;

(2) The location of the noise source relative to the complainant’s property;

(3) The time period during which the noise source is considered by the complainant to be intrusive;

(4) The total duration of the noise produced by the noise source; and

(5) The date and time of the noise measurement survey.

(b) Acoustic data.

(1) A-weighted noise measurement. Utilizing the A-weighted scale of the sound level meter and the “slow” meter response, the Noise Control Officer or his agent shall measure the sound level at any point on the receiver’s closest property line to the noise source, except that for amplified music or sound, the “fast” meter response shall be used.

(2) C-weighted noise measurement. Utilizing the C-weighted scale of a sound level meter and the “fast” meter response, the Noise Control Officer or his agent shall measure the source of the amplified music or sound at the receiver’s closest property line to the noise source.

(1231-CS, Amended, 04/13/2017; 1207-CS, Rep&ReEn, 05/28/2015. Formerly 9-2-306)

5-28-108 Noise limits.

The provisions of this section address noise intrusions over and above the noise normally associated with a given location (intrusions over the ambient level) when the Noise Control Officer conducts an investigation using a sound level meter. The ambient noise varies throughout the community, depending upon proximity to highways, population density, and land use. Different standards are set for various segments of the community which reflect the existing day and nighttime ambient noise levels.

The ambient noise level is defined in terms of statistical parameters which describe the total noise occurring over any hourly time period.

A noise intrusion is judged by comparing such noise statistics with the noise source on, versus such statistics with the noise source off (the ambient). Violations of the provisions of this chapter may be cited in terms of particular levels exceeded or in terms of the length of time the intrusive noise exceeded such standards. Compliance with the noise emission standards as set forth in this section shall constitute the elimination of a noise disturbance.

(2) If the separation of low frequency noise cannot be determined with the meter using either A or C weighting scales and low frequency tones are clearly audible, a sound level measurement in terms of one-third (1/3) octave band frequencies shall be utilized. If this approach is required, a ten (10) dB increase in any one-third (1/3) octave band due to the amplified sound shall be considered a violation of this chapter.

5-28-109 Maximum permissible sound levels by receiving land uses.

The maximum sound levels shall be determined as follows:

(a) The noise standards for the various categories of land use identified by the Noise Control Officer as set forth in TMC 5-28-108, unless otherwise specifically indicated, shall apply to all such property within a designated zone.

(b) No person shall operate, or cause to be operated, any source of sound at any location within the incorporated City, or allow the creation of any noise on property owned, leased, occupied, or otherwise controlled by such person, which causes the noise level, when measured on any other property, either incorporated or unincorporated, to exceed:

(1) The noise standard for that land use as specified in TMC 5-28-108 for a cumulative period of more than thirty (30) minutes in any hour; or

(2) The noise standard plus five (5) dB for a cumulative period of more than fifteen (15) minutes in any hour; or

(3) The noise standard plus ten (10) dB for a cumulative period of more than five (5) minutes in any hour; or

(4) The noise standard plus fifteen (15) dB for a cumulative period of more than one (1) minute in any hour; or

(5) The noise standard plus twenty (20) dB or the maximum measured ambient level for any period of time.

(c) If the measured ambient level differs from that permissible within any of the first four (4) noise limit categories set forth in subsection (b) of this section, the allowable noise exposure standard shall be adjusted in five (5) dB increments in each category as appropriate to encompass or reflect such ambient noise level. In the event the ambient noise level exceeds the fifth noise limit category, the maximum allowable noise level under such category shall be increased to reflect the maximum ambient noise level.

(d) If the measurement location is on a boundary between two (2) different zones, the noise level limit applicable to the lower noise zone, plus five (5) dB, shall apply.

(e) If possible, the ambient noise shall be measured at the same location along the property line utilized in subsection (b) of this section, with the alleged offending noise source inoperative. If for any reason the alleged offending noise source cannot be shut down, the ambient noise shall be estimated by performing a measurement in the same general area of the source but at a sufficient distance such that the noise from the source is at least ten (10) dB below the ambient in order that only the ambient level is measured. If the difference between the ambient and the noise source is five (5) to ten (10) dB, then the level of the ambient itself can be reasonably determined by subtracting a one (1) decibel correction to account for the contribution of the source.

(f) In noise sensitive zones the maximum permissible sound level shall be exceeded by:

(1) Creating or causing the creation of any sound within any noise sensitive zone so as to exceed the specified land use noise standards set forth in TMC 5-28-108 provided conspicuous signs are displayed indicating the presence of the zone; or

(2) Creating or causing the creation of any sound within or adjacent to any noise sensitive zone containing a hospital, nursing home, school, court, or other designated area so as to interfere with the functions of such activity or annoy the occupancy in the activity provided conspicuous signs are displayed indicating the presence of the zone.

5-28-114 Special variances.

(a) The Planning Commission is authorized to grant variances for exceptions from any provision of this chapter, 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.

(b) Any person seeking a variance pursuant to this section shall file an application with the Planning Commission. The application shall contain information which demonstrates that bringing the source of sound or activity for which the variance is sought into compliance with this chapter would constitute an unreasonable hardship on the applicant, on the community, or on other persons. The application shall be accompanied by a fee established by resolution of the City Council. A separate application shall be filed for each noise source; provided, however, several mobile sources under common ownership, or several fixed sources on a single property, may be combined into one (1) application. Notice of an application for a variance shall be published according to this Code. Any individual who claims to be adversely affected by the allowance of the variance may file a statement with the Planning Commission containing any information to support his claim. If at any time the Planning Commission finds that a sufficient controversy exists regarding an application, a public hearing will be held.

(c) In determining whether to grant or deny the application the Planning Commission shall balance the hardship of not granting the variance on the applicant, the community, and other persons 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 variance. Applicants for variances and persons contesting variances may be required to submit such information as the Planning Commission may reasonably require. 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 variance.

(d) Variances shall be granted by notice to the applicant containing all necessary conditions, including a time limit on the permitted activity. The variance shall not become effective until all conditions are agreed to by the applicant. Noncompliance with any condition of the variance shall terminate the variance and subject the person holding it to those provisions of this chapter for which the variance was granted.

(e) A variance shall not exceed three hundred sixty-five (365) days after the date in which it was granted. Applications for the extension of the time limits specified in variances or for the modification of other substantial conditions shall be treated like applications for initial variances under subsection (b) of this section.
