DIVISION 1. GENERALLY


Sec. 21-51. Definitions and standards.

[As used in this division the following words and terms shall have the meanings respectively ascribed:]

A-weighted sound level shall mean the sound pressure level in decibels as measured on a sound level meter using the A-weighting network. The level so read is designated dB(A) or dBA.

Daytime/evening shall mean the hours between six o'clock a.m. and ten o'clock p.m., Sunday through Thursday and six o'clock a.m. and eleven o'clock p.m. Friday and Saturday.

Director shall mean Director of Housing and Neighborhood Services Department.

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

Leq shall mean an average measure of continuous noise that has the equivalent acoustic energy of the fluctuating signal over the same time period. The time period of monitoring will be continuous over any two (2) hours and will use the A-weighting network reported in decibel units.

Nighttime shall mean the hours between ten o'clock p.m. and six o'clock a.m., Sunday through Thursday and eleven o'clock p.m. and six o'clock a.m. Friday and Saturday.

Noise nuisance shall mean any loud, irritating, vexing or disturbing sound originating from a nearby property under separate ownership which causes injury, discomfort, or distress of a person of reasonable nervous sensibilities, or any sound that exceeds the maximum permitted sound levels specified in subsections 21-52(a) (6)(b), (9)--(12), and 21-60(b).

Sound level shall mean the weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network such as A, B or C as specified in American National Standards Institute specifications for sound level meters (ANSI S1.4-1971). If the frequency weighting employed is not indicated, the A-weighting shall apply.

Sound level meter shall mean an instrument which includes a microphone, amplifier, RMS detector, integrator or time averages, output meter, and weighting network used to measure sound pressure levels.

Sec. 21-56. Method of noise measurement.

Whenever portions of this chapter prohibit noise over a certain decibel limit, measurement of said noise shall be made with a decibel meter meeting the standards prescribed by the American National Standards Institute. The instruments shall be maintained in calibration and good working order. Calibration corrections shall be employed in meeting the response specifications prior to every sampling of noise. Measurements recorded shall be taken so as to provide a proper representation of the noise being measured. The microphone shall be positioned so as not to create any unnatural enhancement or diminution of the measured noise. A windscreen for the microphone shall be used. Traffic, aircraft and other transportation noise sources and other background noises shall not be considered in taking measurements except where such background noise interferes with the primary noise being measured. Times when the level of primary noise being measured does not exceed that of the background noise shall be considered as "off times" of the primary noise in determining the corrections from the correction table found in subsection 21-52(b). Except as provided in subsection 21-52(a)(12), measurements may be taken at a point on adjacent public or private property or on either side of an adjacent public right-of-way at or near the boundary line of the property where the noise is generated.

(Ord. No. 94706, § 2(Attach. A), 9-13-01)


Sec. 21-57. Enforcement.

(a) Administrative stop order.

(1) The director, his/her designee, or duly authorized noise abatement officers may issue an order to any person having possession or control over noise generating property to immediately halt any sound which exposes any person, except those excluded in subsection (2) below, to continuous or impulsive noise levels in excess of those shown in Table 1. Within five (5) days following issuance of such an order, the director or his/her duly authorized representative may apply to the appropriate court for an injunction to replace the administrative stop order.

(2) No stop order shall be issued if the only persons exposed to sound levels in excess of those listed in Table 1 are exposed as a result of:

a. Trespass; or

b. Invitation upon private property by the person causing or permitting the sound.

(b) Seizure of noise producing property. The director or his/her duly authorized agents are hereby authorized to apply to any magistrate for an administrative search warrant for the purpose of entering private property to investigate and identify noise nuisance producing devices, machines, instruments, or objects. Such identified property may be seized to summarily abate the noise nuisance if:

(1) A person who is cited for the subject noise violation has been convicted of a violation of any provision of this article within the preceding twelve (12) months, or has been declared to be an "habitual noise nuisance violator" within the preceding twenty-four (24) months; or

(2) The location of the noise nuisance has been declared an habitual noise nuisance source by the director, after appropriate notice to the real property owner or person in possession of the subject noise-source real property, of an administrative hearing to be held for the purpose of hearing evidence and determining whether the subject location is in fact an "habitual noise nuisance source." Upon finding a location to be an "habitual noise nuisance source," the noise producing property shall be immediately seized at the time of any subsequent violations whether or not there is a previous noise nuisance conviction associated with the location.

Such seizures shall be for the purpose of assuring continued cessation of the noise nuisance after the departure of the noise abatement peace officers by securing the instrumentality of the noise nuisance temporarily. The noise producing device, machine, instrument, or object shall be returned to the owner or person proving the right of possession, or to his/her authorized agent, not sooner than twenty-four (24) hours after seizure. Any disputed ownership or right of possession shall be resolved at a property disposition hearing before a magistrate of the city. Seizure of noise nuisance producing property shall be accomplished in addition to and not in lieu of municipal court prosecution and/or a civil suit for injunctive relief and civil penalties.

(d) Declaration of habitual noise nuisance producer. After producing noise measured at decibels in excess of the maximum allow by this article on three (3) separate days within a 12-month period, the noise producer shall be given notice of an administrative hearing before a municipal court magistrate for the purpose of introducing evidence so that the magistrate can make a determination of whether or not the cited noise producer is an "habitual noise nuisance producer," and if the magistrate so finds, a written declaration of said finding shall be signed by the magistrate and kept on file by the abatement officer for a period of one year.

(e) Declaration of habitual noise nuisance location. After the production of noise in excess of that allowed by this article by anyone at the same address or property location on three (3) separate days within a 12-month period, the owner or lessee or person in possession shall be given notice of an administrative hearing before a municipal court magistrate for the purpose of introducing evidence so that the magistrate can make a determination of whether or not the location is an "habitual noise nuisance source," and if the magistrate so finds, a written declaration of said finding shall be signed by the magistrate and shall be kept on file by the abatement officer for a period of one (1) year.

(f) Seizure. If the magistrate determines that the noise producer is an "habitual noise nuisance producer" or that the location is an "habitual noise nuisance source," the noise producing instrument, equipment, or other noise producing item used by the habitual noise nuisance producer may be immediately seized at the time of a subsequent decibel measurement in excess of that allowed by this article. At the time of such seizure, a written notice of the right to an immediate administrative hearing before a municipal court magistrate shall be issued to the habitual noise producer or owner or person in possession of the habitual noise nuisance source. The hearing shall be for the purpose of determining if a noise nuisance actually occurred on which the abatement officer based his seizure, and to voice any complaints about the manner of the seizure. If the noise produced is determined by the magistrate not to constitute a noise nuisance, the subject property shall be immediately delivered to the person from whom it was seized.
