This chapter shall be known as the "noise restrictions ordinance."
(Ord. 7150 § 2 (part), 2008)
9.36.020 - Declaration of policy.
It is declared to be the policy of the city to prohibit unnecessary, excessive and annoying noises from all
sources pursuant to its police power. Noise at certain levels is detrimental to the health and welfare of
the general public. Consequently, it shall be systematically proscribed in the public interest.
(Ord. 7150 § 2 (part), 2008)
9.36.030 - Definitions.
As used in this chapter, unless the context otherwise clearly indicates, the words and phrases used in
the ordinance codified in this chapter are defined as follows:
A. "Ambient noise" means the all-encompassing noise associated with a given environment,
being usually a composite of many sources near and far. For the purpose of this chapter, ambient
noise level is the level obtained when the noise level is averaged over a period of 15 minutes
without inclusion of noise from isolated identifiable sources, at the location and time of day near
that at which a comparison is to be made. This value shall not include noise from occasional, or
occasional and transient sources.
B. "A-weighted sound level" means the sound level in decibels as measured on sound level
meter using the A weighting network. The level so read is designated "dB(A)" or "dBA."

Chapter 9.36 - NOISE RESTRICTIONS*
C. "Commercial purpose" means and includes the use, operation or maintenance of any sound
amplifying equipment for the purpose of advertising any business, or any goods, or any services,
or for the purpose of attracting the attention of the public to, or advertising for, or soliciting
patronage or customers to or for any performance, show, entertainment, exhibition or event, or for
the purpose of demonstrating such sound equipment.
D. "Decibel" means a unit measure of sound (noise) level. It is a unit for expressing the relative
intensity of sounds on a scale from zero for the average least perceptible sound to about 130 for
the average pain level; also a unit for expressing the ratio of two amounts of electric or acoustic
signal power equal to 10 times the common logarithm of this ratio.
E. "Emergency work" means work made necessary to restore property to a safe condition
following a public calamity or work required to protect persons or property from an imminent
exposure to danger or work by private or public utilities when restoring utility service.
F.
"General noise" means noise from any source not specifically exempted in this chapter.
G. "Noncommercial purpose" means the use, operation or maintenance of any sound equipment
for other than a commercial purpose. "Noncommercial purpose" means and includes, but shall not
be limited to, religious, philanthropic, political, patriotic and charitable purposes.
H. "Property line" means the line that separates private property or the event from the public
right-of-way.
I.
"Sound amplifying equipment" means any machine or device for the amplification of the
human voice, music or any other sound. "Sound amplifying equipment" shall not include standard
automobile radios when used and heard only by the occupants of the vehicle in which the
automobile radio is installed. "Sound amplifying equipment," as used in this chapter, shall not
include warning devices on authorized emergency vehicles or horns or other warning devices on
any vehicle used only for traffic safety purposes.
J. "Sound level" (noise level), in decibels (dB), is the sound measured with the A weighting and
slow response by a sound level meter.
K. "Sound level meter" means an instrument including a microphone, an amplifier, an output
meter and frequency weighting networks for the measurement of sound levels which satisfies the
pertinent requirements in American Standard Specifications for sound level meters S1.4-1971 or
the most recent revision thereof.
L. Supplementary Definitions of Technical Terms. Definitions of technical terms not defined
herein shall be obtained from the American National Standards Institute's Acoustical Terminology
S1-1-1971 or any revision thereof.
(Ord. 7150 § 2 (part), 2008)
9.36.040 - Ambient noise level.
A. When "ambient noise level" is referred to in this chapter, it means the actual measured ambient
noise level.
B. Any sound level measurement made pursuant to the provisions of this chapter shall be measured
with a sound level meter using the A weighting.

constitute a detriment to traffic safety; or
c. The registration statement required reveals that the applicant would violate the
provisions set forth in subsection E of this section or any other provisions of this chapter; or
d.
Failure to file said statement within the prescribed period.
In the event the registration statement is disapproved, the director of finance shall cause to be
endorsed upon the statement the reasons for disapproval, and return it forthwith to applicant.
2. Appeal of Decision. Any person aggrieved by disapproval of a registration statement may file
a written appeal with the city manager within five (5) days of receipt of the notice of disapproval,
setting forth all the facts which the applicant wishes the city manager to consider. The city
