(Ord. 2043 § 1 (part), 2004).

A.

Purpose. It is declared to be the policy of the city to prohibit unnecessary, excessive, and annoying sound levels from all sources. In compliance with this policy, Campbell is designated a quiet city. At certain levels, sounds are detrimental to the health and welfare of the citizenry and, in the public interest, shall be systematically proscribed. It is the purpose of this chapter to prescribe standards for and to provide an effective and readily available remedy for violations of this chapter.

B.

Definitions. As used in this chapter, unless the context otherwise clearly indicates, the words and phrases used in this chapter are defined as follows:

"A-weighting" means a filter network designed to transform a frequency spectrum to that which is heard by the human ear.

"Decibel (dB)" means a unit for measuring the amplitude of sound, equal to twenty times the logarithm to the base ten of the ratio of the pressure of the sound measured to the reference pressure of zero decibels, which is twenty micropascals.

"Impulsive sound" means a sound of short duration, usually less than one second, with an abrupt onset and rapid decay. Examples of impulsive sounds include explosions, drop impacts, and firearm discharge.

"Noise" means any loud discordant or disagreeable sound or sounds.

"Noise level" expressed in decibels (dB), means a logarithmic indication of the ratio between the acoustic energy present at a given location and the lowest amount of acoustic energy audible to sensitive human ears and weighted by frequency to account for characteristics of human hearing, as given in the American National Standards Institute Standard S1.1, Acoustic Terminology, Paragraph 2.9, or successor references.

"Noise level measurement" means the procedure of measuring sound consisting of the usage of a precision sound level meter (SLM), as defined in this section, set to "fast" response. If the sound level meter is analog with a VU meter, then the response shall be "slow" unless the noise issue is impulsive. The meter shall be calibrated before any measurements and the microphone shall be a minimum of three and one-half feet from any wall, floor, or other large sound-reflecting surface. The meter shall be protected from wind or other extraneous noise by the use of screens, shields, or other appropriate devices.

"Powered equipment" means a motorized device powered by electricity or fuel used for property maintenance and/or landscape maintenance. Powered equipment includes: lawn mowers, edgers, parking lot sweepers, blowers, wood chippers, vacuums, and similar devices.

"Precision sound level meter" means a sound pressure level measuring instrument that conforms to the American National Standards Institute (ANSI) specification S1.4 for Type 1 or Type 2 measuring instruments.

"Sensitive receptor" means a land use in which there is a reasonable degree of sensitivity to noise. Such uses include single-family and multi-family residential uses, schools, hospitals, churches, rest homes, cemeteries, public libraries, and other sensitive uses as determined by the enforcement officer.

C.

Applicability. It is unlawful for any person, at any location within the city, to create any noise or to allow the creation of any noise on property leased, occupied, owned, or otherwise controlled by the person which does not comply with the provisions of this chapter, unless the provisions of either subsection E or subsection G of this section, have been met.

D.

Noise measurement.

1.

Noise measurement equipment. Any noise measurement made in compliance with this chapter shall be made with a sound level meter using the A-weighting network at slow meter response. Fast meter response shall be used for impulsive type noise. Calibration of the measurement equipment utilizing an acoustical calibrator meeting American National Standards Institute (ANSI) standards shall be performed immediately prior to recording any sound data.

2.

Location of noise measurement. Exterior sound levels shall be measured at the property line or at any location within the property of the affected sensitive receptor. Sound measurements shall be taken in a manner and location so that it can be determined whether sound level standards are exceeded at the property line. Where practical, the microphone of the sound level meter shall be positioned three to five feet above the ground and away from reflective surfaces. The actual location of the sound measurements shall be at the discretion of the enforcement officer.

E.

Residential noise standards.

1.

Noise from stationary sources. New residential development shall conform to a stationary source noise exposure standard of sixty-five dBA for exterior noise levels and forty-five dBA for interior noise levels.

2.

Traffic-related noise. New residential development shall conform to a traffic-related noise exposure standard of sixty dBA CNEL for outdoor noise in noise-sensitive outdoor activity areas and forty-five dBA CNEL for indoor noise. New development that does not and cannot be made to conform to this standard shall not be allowed.

F.

Acoustical studies required.

1.

Acoustical studies. Acoustical studies are required for all new noise-sensitive projects that may be affected by existing noise from stationary sources, including all new residential developments with a noise exposure greater than 60 dBA CNEL. The studies shall also satisfy the requirements set forth in Title 24, Part 2, of the California Administrative Code, Noise Insulation Standards, for multiple-family attached residential projects, hotels, motels, etc., regulated by Title 24.

2.

Mitigation measures. Where acoustical studies show that existing stationary noise sources exceed, or will exceed maximum allowable noise levels, mitigation shall be identified to reduce noise exposure to or below the allowable levels of this chapter. Mitigation measures may include increased setbacks between uses, earth berms, sound walls, landscaping, and site design that shields noise-sensitive uses with nonsensitive structures, (e.g., parking lots, utility areas and garages), or orientation of buildings to shield outdoor spaces from noise sources. In cases where sound walls are used as mitigation, they should be encouraged to help create an attractive setting with features such as setbacks, changes in alignment, detail and texture, pedestrian access (if appropriate) and landscaping.

G.

Exemptions. Sound or noise emanating from the following sources and activities are exempt from the provisions of this chapter:

1.

Municipal Code provisions. The provisions of this chapter shall not apply where noise standards are specified elsewhere in the Municipal Code.
