HomeMy WebLinkAbout03142019 ZPC Agenda Item 6 Exhibit"A" Amend Chapter 54,Article II. Noise by replacing Sections 54-39 through 54-43 in their entirety and replacing with the proposal below: ARTICLE II.-NOISE Sec.54-39.-Purpose. The noise level prohibitions of this Article are designed to ensure that the City remains a quiet and peaceful community free from loud noises which would unnecessarily cause distress to the average citizen. Sec. 54-40.-Application. All noises created and heard within the municipal limits of the City shall be consistent with the values identified in Table 54-39,Noise Level Prohibitions,and shall be measured in decibels pursuant to Sec.54- 45, Measurements. Sec.54-41.-Regulations. (a) Noise Level Prohibitions.Table 54-39,Noise Level Prohibitions, sets out the maximum allowable decibel levels that may be heard throughout the municipal boundaries of the City. These prohibitions are applicable regardless of the duration of the noise at issue. Table 54-39,Noise Level Prohibitions Normal Noise Period 7:00 am—8 pm 65 dB(A) Low Noise Period 8 pm—7:00 am 55 dB(A) The measurement of the required decibel levels must be recorded according to the requirements of Sec. 4-45,Measurements. (b) Prohibited Noise during Low Noise Period. Because it is reasonable to believe that the noise created will be greater than the regulation,the following noises are explicitly prohibited during the Low Noise Period: (1) Engine powered equipment that can be operated by hand; (2) Truck deliveries(including any associated moving, idling, loading, and unloading); and (3) Public address and other amplified sound systems. Sec. 54-42. -Exemptions. (a) Exemptions from Normal Noise Period and Low Noise Period. The following noises are exempt from the decibel level requirements during both the Normal Noise and Low Noise Periods as shown in Table 54-39, Noise Level Prohibitions: (1) Home Security Alarms, provided that they are in compliance with Chapter 26, Electricity and Alarm Systems,of the City's Code of Ordinances; (2) Car Alarms, provided that they are properly functioning; (3) Any noise generated by an emergency pressure relief value or sewer lift station, (4) Aircraft; and (5) Emergency Vehicles, including but not limited to city police and emergency medical services. (b) Exemptions from Normal Noise Period Requirements Only.The following noises are exempt from the decibel level requirement during the Normal Noise Period as shown in Table 54-39,Noise Level Prohibitions: (1) Waste and recycle hauling; (2) Construction,grading,or demolition noises when the person generating the noise has received a valid permit pursuant to Chapter 18, Building and Construction;and (3) Street events, provided that a valid permit pursuant to Chapter 46,Article IV,Street Events, Etc., has been issued by the City. Sec. 54-43.-lniunction to Prohibit Noise The City reserves the right to submit to a court of competent jurisdiction any request for an injunction to prevent any person from creating noise by any means that can be proven to be greater than the noise requirements found in Table 54-39,Noise Level Prohibitions. Sec. 54-44.-Violations (a) Issuance of Citations.The Public Works Director or his designee is authorized to issue citations for violations of the terms and provisions of this Article to the owner or occupant of the property upon which condition exists. (b) Procedures and Penalties. Any violation of this Article, and any associated penalties that result from it, shall be dealt with consistent with the requirements of Section 1-7, General penalties for violations;alternative enforcement, of the City's Code of Ordinances. Sec.54-45.-Measurements Noise shall be measured in accordance with the following: (a) All decibel readings shall be recorded at the property boundary line of the property at issue. Under no circumstances should a decibel reading be recorded while on the premise. (b) Noise levels shall be measured in decibels and A-weighted. The unit of measurement shall be designated "dB(A)." (c) The microphone of the decibel recording meter shall be positioned so as not to create any unnatural enhancement or diminution of the measured sound. A windscreen for the microphone shall be used. (d) Calibrations shall be employed which meet ANSI S1.40-1984 prior to and immediately after every sampling of sound. (e) Measurements must be made with a type 1 or type 2 calibrated sound level meter using the A- weighting scale and the slow meter response as specified by the American National Standards Institute(ANSI 51.4-1984/85A). Existing regulations ARTICLE II.-NOISE Sec. 54-39.- Unreasonable noise prohibited. Causing unreasonable loud and disturbing noise in the city is hereby prohibited and shall constitute an offense. Noises of such character, intensity and duration as are reasonably calculated to be detrimental to the life or health of any ordinary reasonable person are hereby prohibited. This article applies to noise heard within the city, regardless of the point of origin. Sec. 54-40.-Enumeration of specific noises. The following noises, among others, are declared to be loud, disturbing noises in violation of this article(this enumeration is neither exhaustive nor exclusive of other noises): (1) The noise of any horn or signal device on any automobile, motorcycle, bus or other vehicle while not in motion, except as a danger signal if another vehicle is approaching apparently out of control; the same noise made while in motion, except as a danger signal after, or as, brakes are being applied and deceleration of the vehicle is intended; any unreasonably loud or harsh sound created by means of any such signal device; and the sound of such device made for any unreasonable period of time. (2) The sound of: a. Any vehicular or portable radio, phonograph, disc player, tape player or any musical instrument that is plainly audible outdoors from a distance of 100 feet or more(or 50 feet or more during residential quiet hours); or b. Any loudspeaker or amplifier operated outdoors during residential quiet hours that is plainly audible from a distance of 50 feet or more. "Plainly audible" means any sound that can be detected by a person using his or her unaided hearing faculties. Example: If the sound source under investigation is a portable or personal vehicular sound amplification or reproduction device, the enforcement officer need not determine the title of a song, specific words, or the artist performing the song. The detection of the rhythmic base component of the music is sufficient to constitute a plainly audible sound. (3) The sound of any automobile, motorcycle or other vehicle so out of repair, so loaded or operated in such manner that it creates loud noises such as spinning or squealing tires, grating, grinding, rattling or other noise. (4) The sound of any mechanical equipment installed at a fixed location (Examples: fans, compressors, condensers, pumps, etc.), if: a. When the equipment is operating, noise from the equipment is discernable at a point outside the boundaries of the site where it is installed, and noise at that point is measured at a level of 70dB(A)or higher; and b. Immediately before or after operation of the equipment, noise at the same point is measured at a level of 65dB(A)or lower. All sound level measurements shall be made as provided in this article. (5) The sound of a discharge into the open air of the exhaust of any internal combustion motor or engine, except through a muffler or other device which will effectively prevent loud or explosive noises therefrom. (6) The sound of any mechanical device operated by compressed air, except pneumatic drills, unless the noise thereby created is effectively muffled and reduced. (7) Loud and excessive noise resulting from the erection (including excavation), demolition, alteration or repair of any structure during residential quiet hours, unless the noise is made in case of urgent necessity in the interest of public safety, and then only with a permit from the building official, which permit may only be renewed for a period of three days or fewer while the emergency continues. (8) Any excessive noise made on any street adjacent to any school, institution of learning or court while the same is in session, or adjacent to any hospital at any time, which noise unreasonably interferes with the working of any such institution, provided conspicuous signs are displayed in such street indicating that the same is a school, hospital or court street. (9) Any loud and excessive noise resulting from the loading or unloading of any vehicle or container, or the opening or destruction of bales, boxes, crates or containers. (10) The sound of any bell, gong, whistle, siren, or other alarm or signaling device installed at a fixed location which is reasonably calculated to disturb a person of ordinary disposition if such person were in the vicinity thereof. Exceptions: This does not apply to: a. An emergency alarm operated by the fire department or other governmental agency; or b. An alarm system permitted and operated in compliance with applicable regulations, including automatic shutoff rules; see, e.g. chapter 26. (11) Shouts or cries of peddlers or vendors which disturbs the quiet and peace of the neighborhood. (12) The sound of any drum, loudspeaker or other instrument or device used to attract attention to any performance, show or sale of merchandise. (13) The sound made by loudspeakers or amplifiers on trucks or other vehicles. (14) The sound made by leafblowers, lawnmowers and other lawn maintenance equipment, if: a. The equipment is powered by internal combustion; and b. The equipment is operated within 200 feet of an occupied residential building during residential quiet hours. Sec. 54-41.-Affirmative defenses. (a) Request to cease . It shall be an affirmative defense in any prosecution under this article that a request to cease causing the noise in question was given neither to the person charged nor to any officer, agent, employee or representative of the person charged. All peace officers and other city enforcement personnel are hereby authorized to request that persons cease causing noises that are apparently in violation of this article. Nothing herein limits the right of others to make such requests. (b) Urgent public projects . It shall be an affirmative defense, in any prosecution under this article, that the offending noise was: (1) Necessary for a public project for which the public works director has certified, in writing, that expedited completion is urgently needed and in the public interest; and (2) Made after 7:00 a.m. and before 9:00 p.m. (c) Measured noise levels . It shall be an affirmative defense, in any prosecution under this article, that a measured noise level was actually produced by some person or thing other than that alleged to have caused the noise. (d) Registered outdoor events . It shall be an affirmative defense, in any prosecution under this article, that the offending noise resulted from an outdoor concert or similar event that: (1) Was registered at least 48 hours in advance with the chief of police; (2) Did not last more than four hours, of which no more than two hours were during residential quiet hours; and (3) Was otherwise conducted to avoid disturbance of persons within nearby dwellings. (e) Speech or expression . The affirmative defenses for speech or expression enumerated in V.T.C.A., Penal Code § 42.04 (prior order to move, disperse or remedy) shall also be available in any prosecutions for violations of this article. Sec. 54-42.-Injunction as additional remedy. As an additional remedy, the noise made by any activity, device, instrument, vehicle or machinery in violation of any provision hereof and which causes discomfort or annoyance to reasonable persons of normal sensitivity, or which endangers the comfort, repose, health or peace of residents in the area, shall be deemed, and is declared to be, a public nuisance and may be subject to abatement by a restraining order or injunction issued by a court of competent jurisdiction. Sec. 54-43.-Sound level measurements. Sound level measurements under this article shall be made in accordance with the following criteria: (1) Measurements must be made with a type 1 or type 2 calibrated sound level meter using the A- weighting scale and the slow meter response as specified by the American National Standards Institute(ANSI S1.4-1984/85A). (2) Noise levels shall be measured in decibels and A-weighted. The unit of measurement shall be designated a"dB(A)." (3) Meters shall be maintained in calibration and good working order. (4) Calibrations shall be employed which meet ANSI S1.40-1984 prior to and immediately after every sampling of sound. (5) Measurements recorded shall be taken so as to provide a proper representation of the sound being measured. (6) The microphone of the meter shall be positioned so as not to create any unnatural enhancement or diminution of the measured sound. A windscreen for the microphone shall be used. c J O a 4�Q M }+ Y a) co 0 '^ a) E v o 0 4� ,}t—I c C •cr co O M O a) 01 1.2 V) L "O 0 7 o O in O al 41 . t T t E D t c = d4 c O. +-' M 4 4-+ al vi N 03 to o 3 c (1) a v) -0 -a c pi) aJ c 4-•U v O a) Ill • L c n: cu O O co c 0 1 0 to +S p t c• c c o .'n, 0c O c t O 0 3 O vi E L' a, 2 13 x • c CO H C7 a.
