The following words, phrases and terms as used in this chapter
shall have the meaning as indicated below:
"Ambient noise level"
means the all-encompassing noise level associated with a
given environment, being a composite of sounds from all sources, excluding
the alleged offensive noise, at the location and approximate time
at which a comparison with the alleged offensive noise is to be made.
"A-weighted decibel (dBA)"
means the overall frequency-weighted sound level in decibels
that approximates the frequency response of the human ear as represented
by the A-weighted network. The reference pressure is 20 micropascals.
"Commercial property"
means a parcel of real property which is developed and used
either in part or in whole for commercial purposes including, but
not limited to, retail and wholesale businesses and professional offices.
"Cumulative period"
means an additive period or time composed of individual time
segments which may be continuous or interrupted.
"Decibel (dB)"
means a unit which denotes the ratio between two quantities
which are proportional to power; the number of decibels corresponding
to the ratio of two amounts of power is 10 times the logarithm to
the base 10 of this ratio.
"Domestic power tool"
means a mechanically-powered saw, sander, drill, grinder,
lawn or garden tool, snow blower, leaf blower or similar device that
is used in residential areas for work that is typically done by or
for residential occupants.
"Emergency machinery, vehicle or work"
means any machinery, vehicle or work used, employed or performed
in an effort to protect, provide or restore safe conditions in the
community or for the citizenry, or work by private or public utilities
when restoring utility service.
"Equivalent continuous sound level (Leq)"
means the value of an equivalent, steady sound level which,
in a stated time period, has the same sound energy as the time-varying
sound. Thus, the Leq metric is a single numerical value that represents
the equivalent amount of variable sound energy received at a location
over the specified duration.
"Fixed noise source"
means a stationary device or point source which creates sounds
while fixed or motionless, including, but not limited to, industrial
and commercial machinery and equipment, pumps, fans, compressors,
generators, air conditioners and refrigeration equipment, or an area
source such as a special event on a property. That is, all sources
that are non-mobile transportation sources (e.g., vehicle traffic
on public roads and aircraft).
"Grading"
means any excavating or filling of earth material, or any
combination thereof, conducted to prepare said site for construction
or the placement of the improvements thereon.
"Impact noise"
means the noise produced by the collision of one mass in
motion with a second mass which may be either in motion or at rest.
"Impulsive noise"
means sound of short duration, usually less than one second,
with an abrupt onset and rapid decay.
"Industrial property"
means a parcel of real property which is developed and used
in part or in whole for manufacturing purposes including research
and development uses.

by using a sound level meter at slow response with a reference pressure
of 20 micropascals (micronewtons per square meter). The unit of measurement
shall be designated as dBA.
"Parcel"

venture, corporation or any entity, public or private in nature.
"Predominant tone noise"
means a noise characterized by a predominant frequency or
frequencies so that other frequencies cannot be readily distinguished.
"Residential property"
means a parcel of real property which is developed and used
either in part or in whole for residential purposes, other than transient
uses such as hotels or motels.
"Simple tone noise"
means a noise characterized by a predominant frequency or
frequencies so that other frequencies cannot be readily distinguished.
In case of dispute, a simple tone noise shall exist if the one-third
octave band sound pressure level in the band with the tone exceeds
the arithmetic average of the sound pressure levels of the two contiguous
one-third octave bands by five dB for center frequencies of 500 Hz
and above and by eight dB for center frequencies between 160 and 400
Hz and by 15 dB for center frequencies less than or equal to 125 Hz.
"Sound amplifying equipment"

the human voice, music, or any other sound, excluding standard automobile
stereos when used and heard only by the occupants of the vehicle and,
as used in this chapter, warning devices on authorized emergency vehicles
or horns or other warning devices on any vehicle used for traffic
safety purposes.
"Sound pressure level"
of a sound, in decibels, means 20 times the logarithm to
the base of 10 of the ratio of the pressure of the sound to the reference
pressure of 20 micropascals.
"Vibration decibel (VdB)"
means a measure of vibration expressed on a logarithmic scale
with the reference velocity of one micro-inch per second (1x10-6 in/sec).
"Vibration-sensitive use"
means residential, hotels, motels, schools, hospitals and
medical offices with vibration-sensitive equipment, churches, cultural
land uses, commercial, office and government uses. Outdoor areas with
no buildings and industrial and manufacturing uses are not considered
vibration sensitive.
(2379-7/79, 4222-9/21)
Any noise level measurements made pursuant to the provisions of this chapter shall be performed using a sound level meter which meets at least American National Standards Institute (ANSI) Type 2 standards. While the exterior noise standards in Section
8.40.050 are applied to the property line of the receiving use, the location for measuring noise levels may be at any legally accessible vantage point where a reasonable person would conclude the noise may exceed this chapter's noise standards. All noise level measurements shall be performed in accordance with the procedures established by the City and shall be at a height of at least four feet, at least four feet away from reflective surfaces, and for a duration of at least 15 minutes, where feasible. The measurement shall be made using the A-weighting network (dBA) with "slow" meter response. Impulsive or impact noises shall be measured using "fast" meter response. The purpose of the measurement is to determine if the alleged noise violation exceeds the standards established in Section
8.40.050. If for any reason the alleged offending noise cannot be turned off, shut down or temporarily removed from the area, then the ambient noise shall be estimated by performing a representative measurement in the same general area of the source but at a sufficient distance such that the noise source is inaudible.
(2379-7/79, 3940-7/12, 4222-9/21)
A. The
following exterior noise standards shall apply to the applicable land
use. It is unlawful for any person at any location within the incorporated
area of the City to create any noise due to a fixed noise source (or
any mobile source not preempted by State or Federal laws), or to allow
the creation of any noise on property owned, leased, occupied, or
otherwise controlled by such person, which causes the noise level
when measured at the property line of any residential, hotel, motel,
public institutional, recreational, or commercial property, either
within or outside the City, to exceed the applicable noise standards:
