Public disturbance noise includes, but is not limited to, those noises specifically enumerated in subsections (a) and (b) of this section:

Any sound which occurs between ten p.m. in the evening and six a.m. the following morning and shall include, but not be limited to, the following:
(1) 
Any sound made by the construction, excavation, repair, demolition, destruction or alteration of any building, property or upon any building site;
(2) 
Any sound made by the discharge of exhaust gases from an internal combustion engine except through a muffler, which sound is heard within a residential zone;
(3) 
Any sound made by the operation of any motorcycle, motorbike, off-road or all-terrain vehicle in the city on any property not a part of the public street system when such motorcycle, motorbike, off-road or all-terrain vehicle does not conform to muffler standards required for operation on public streets and such sound is heard within a residential district;
(4) 
Any sound made by a loud speaker or sound amplifier exterior to any building for commercial advertising or sales purposes, or for attracting the attention of the public to any performance, show or other event;

Any sound heard in a residential zone made at any time by using, operating, playing or permitting to be used, operated or played, any amplification device or equipment, including, but not limited to, radios, musical instruments, phonographs, tape players, CD players or recorders, sound amplification systems or other machines or devices used for producing or reproducing sound at any time with volume louder than is audible by the owners or occupiers of dwelling units within such residential zone, where said owners or occupiers of the dwelling units are within such dwelling units, and where such dwelling units are twenty feet or more from the source of the noise, and where such dwelling units are not attached to another building or dwelling unit from which the sound emanates.
(Ord. 1035 § 1, 2023)
No person, who is the operator or owner of a vehicle, shall permit any audio system in or on that vehicle to make any sound which is audible outside the passenger compartment at a frequency below one hundred thirty-eight Hz, or which is otherwise amplified by a subwoofer, or to allow the sound of other audible frequencies to be heard more than fifty feet outside the passenger compartment.
(Ord. 1035 § 1, 2023)

(b) 
Exceptions may be granted to any person from any requirement of Section 9.48.020 if findings are made that immediate compliance with such requirement cannot be achieved because of special circumstances rendering immediate compliance unreasonable in light of economic or physical factors, encroachment upon existing noise source, or because of nonavailability of feasible technology or control methods.
(c)

The city administrator shall make a recommendation for approval or disapproval to the city council in all such cases. The city council shall then make a final determination of approval or disapproval of an exception.

(d) 
Any exception or renewal thereof shall be granted only for the minimum time period found to be necessary under the circumstances.

Sources of noise, subject to this chapter, shall immediately comply with the requirements of this chapter, except in extraordinary circumstances where overriding considerations of public interest dictate the issuance of an exception.
(Ord. 1035 § 1, 2023)
Noise measurement is not necessary for the enforcement of Section 9.48.020. If noise measurement for the purpose of enforcing the provisions of any section of this chapter is used, it shall be measured in dBA with a sound level meter in good operating condition, and properly calibrated. Enforcement of Sections 9.48.010 and 9.48.020 shall be undertaken upon receipt of complaints by two or more persons occupying separate, detached residences, or employed on separate properties in the area affected by the noise. Whenever any police officer, commissioned by the city, has reason to believe that any person is in violation of Section 9.48.010 or 9.48.020, the officer shall, before the issuance of an infraction, notify such person of the violation and request compliance with this chapter. Failure of any person to cease after notification thereof of any violation of Section 9.48.020 shall be cause for the issuance of an infraction.
(Ord. 1035 § 1, 2023)
Any person found to be in violation of any provision of this chapter shall be deemed to have committed an infraction, and for each violation shall be subject to a civil penalty as outlined in the master fee schedule as amended from time to time. Each day that the violation continues shall be deemed a separate violation.
(Ord. 1035 § 1, 2023)
The provisions of this chapter shall be cumulative and nonexclusive and shall not affect any other claim, cause of action or remedy; nor, unless specifically provided, shall it be deemed to repeal, amend or modify any law, ordinance or regulation relating to noise, but shall be deemed in addition to legislation and common law on noise.
(Ord. 1035 § 1, 2023)
If any section, sentence, clause or phrase of this chapter shall be held to be unconstitutional or invalid, the remainder of this chapter shall, nevertheless, remain in full force and effect.
