(A) General provisions.
(1) Scope. This section applies to the control of all sound and noise within the City of Ferris.
(2) Overview. This section is designed to regulate noise by various alternative means in order to allow the enforcement of noise regulations at times when and by persons for whom noise meters are not available. A noise may be in violation of this section because it is disturbing to a reasonable person of ordinary sensibilities or because it exceeds the decibel level restrictions provided below. If a noise violates more than one of these provisions, the violation will be enforced under whichever provision is most applicable to the situation as determined by the enforcement officer of the city.
(B) Definitions. For the purpose of this section, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
AMBIENT NOISE. The all-encompassing noise level associated with a given environment, being a composite of sounds from all sources at the location, constituting the normal or existing level of environmental noise at a given location.
A-WEIGHTING (dBA). The sound pressure level in decibels as measured on a sound level meter using the A-weighted network. The level so read is designated dB(A) or dBA.
BOUNDING REAL PROPERTY LINE. An imaginary line at the ground and its vertical extension which separates the real property owned or occupied by one person from that owned or occupied by another person.
DECIBEL (dBA). The unit of measurement for sound pressure at a specified location.
GOVERNMENTAL FUNCTION. Work conducted by a governmental entity in the interest of the community.
RESIDENTIAL. Property zoned for residential use in accordance with the city’s zoning ordinance.
SOUND LEVEL. The instantaneous sound pressure level measured in decibels obtained by the use of a sound level meter set for A-weighting on slow integration speed, unless otherwise noted.
UNREASONABLE NOISE.
(a) Any unreasonably loud, disturbing, and unnecessary noise which causes material distress, discomfort or injury to persons of ordinary sensibilities in the immediate vicinity thereof: or
(b) Any noise of such character, intensity and continued duration, which substantially interferes with the comfortable enjoyment of private homes by persons of ordinary sensibilities.
(C) Restrictions on decibel levels.
(1) Maximum sound levels. During the times and in the zoning districts (except for activities originating in industrial zoning districts) set out below, the activities that create a sound pressure level on the complainant’s bounding real property line that exceeds the maximum allowable sound level (dBA) below are declared to be public nuisances:
(a) All residential zoning districts:
Daytime: 7 a.m. to 10 p.m. = 70 dBA
Nighttime: 10 p.m. to 7 a.m. = 60 dBA
(b) All non-residential and mixed-use zoning districts (excluding industrial zoning districts):
Daytime: 7 a.m. to 10 p.m. = 80 dBA
Nighttime: 10 p.m. to 7 a.m. = 70 dBA
(c) All zoning where ambient noise level exceeds the prescribed maximum level:
7 a.m. to 10 p.m. = Existing Ambient (dBA) + 3 dBA
10 p.m. to 7 a.m. = Existing Ambient (dBA)
(2) Method of noise measurement. Noise measurements shall be a minimum of 30 seconds in duration. Decibel levels are measured from the complainant’s property line. For residential districts adjacent to other districts (excluding industrial zoning districts) the residential decibel levels apply when measured from a residential complainant’s property line. Violations will be determined based on the highest registered reading in that measurement period. All measurement levels will be inclusive of any ambient noise that exists at the time of the measurement.
(D) Noise prohibited.
(1) In addition to the other noise restrictions in this section, no person shall make, cause, suffer, allow or permit unreasonable noise in such a manner, or with such volume, intensity or duration, so as to disturb a reasonable person of ordinary sensibilities. A decibel level shall not be required for the enforcement of this division.
(2) This division is intended to apply to, but is not limited to, unreasonable noises in the form of:
(a) Amplifiers in public right-of-way and on city property. The use of a bullhorn, loudspeaker, or other amplification is prohibited in the public right-of-way and on City of Ferris property, unless permitted as an exception below. Exceptions:
1. Public safety official while performing their duties.
2. Persons with written permission to utilize said equipment from the City Manager or his or her designee.
3. Persons with permission from pertinent city department director or designee.
(b) Animals. It shall be unlawful to keep, or to permit the keeping of, any dog(s) or rooster(s) or any other bird or animal that creates any bark, cry, crow, or other sound on a frequent, repetitive or continuous basis for ten minutes or longer.
(c) Construction work. Noise created by construction work within 300 feet of an occupied residential structure involving the erection, excavation, demolition, alteration, or repair of any building, structure, or flatwork is prohibited as follows:
1. Before 7:00 a.m. or after 8:00 p.m. Monday - Friday.
2. Before 9:00 a.m. or after 8:00 p.m. Saturday - Sunday.
(d) Music. The playing of any music or musical instrument in such manner or with such volume or bass, particularly during the nighttime hours described in division (C) of this section Restrictions on Decibel Levels, as to annoy or disturb the quiet, comfort or repose of persons of ordinary sensibilities in any dwelling, hotel or other type of residence.
(e) Horns or other signal devices. The continued or frequent sounding of any horn, air horn, or signal device on any vehicle except as a danger or warning signal; the creation by means of any such signal device of any unreasonably loud or harsh noise for any unnecessary and unreasonable period of time.
(f) Operation of motor vehicles. The revving of any engine, the playing of any music with such volume or bass, or the operation of any vehicle so out of repair, so loaded or in such manner as to create loud or unnecessary grating, grinding, jarring, rattling, or squealing noise or vibrations.
(E) Exemptions. The following acts and sounds shall be exempt from the requirements of this section.
(1) Noise generated due to normal building conditioning and ventilation and property maintenance.
(2) Noise generated on public and school property, as permitted by the property owner.
