All uses and activities established after the effective date of this Zoning Ordinance shall comply with the following standards:
(a) Noise.
(1) The sound level of any operation (other than the operation of motor vehicles or other transportation facilities, operations involved in the construction or demolition of structures, emergency alarm signals or time signals, institutional or governmental or quasi-public activities) shall not exceed the decibel levels in the designated octave bands as stated below. The sound pressure level shall be measured with a Sound Level Meter and an Octave Band Analyzer that conforms to specifications published by the American Standards Association.
(2) Sound pressure levels shall be measured at the lot line of the property from which the emission occurs. The maximum permissible sound pressure levels for smooth and continuous noise shall be as follows: (All of the decibel levels stated below shall apply in each case.)
Octave Band Center Frequency Hertz | Maximum Permitted Sound Pressure Level Deceibels re 0.0002 Microbar |
31.5 | 83 |
63 | 78 |
125 | 72 |
250 | 64 |
500 | 57 |
1000 | 51 |
2000 | 46 |
4000 | 41 |
8000 | 38 |
(3) If the noise is not smooth and continuous or is radiated during sleeping hours, the decibel levels given above shall be adjusted as follows:
Type of Operation or Character of Noise | Corrections in Decibels |
Noise occurs between the hours of 10:00 p.m. and 7:00 a.m. | -6 |
Noise occurs less than five percent (5%) of any one-hour period. | +6 |
Noise is of periodic character (hum scream, etc.,) or is of impulsive character (hammering, etc.). (In the case of impulsive noise, the correction shall apply only to the average pressure during an impulse, and impulse peaks shall not exceed the basic standards given above.) | -6 |
(b) Vibrations. No use shall cause earth vibrations or concussions detectable without the aid of instruments beyond its lot lines with the exception of vibration produced as a result of construction or demolition operations.
(c) Dust, Fumes, Vapors and Gases.
(1) The emission of dust, dirt, fly ash, fumes, vapors or gases which can cause any damage to human health, animals, vegetation, or property, or which can cause any soiling or staining of persons or property at any point beyond the lot line of the use creating the emission, is prohibited.
(2) No smoke shall be emitted from any chimney or other source, of visible gray opacity greater than No. 1 on the Ringlemann Smoke Chart as published by the U. S Bureau of Mines, except that smoke of a shade not darker than No. 2 on the Ringlemann Chart may be emitted for not more than six minutes in any thirty minute period.
(3) No emission of liquid or solid particles from any chimney or other source shall exceed five-tenths grains per cubic foot of the covering gas at any point beyond the lot line of the use creating the emission. At the source, allowable particulate matter in combustion gases shall not exceed one pound per million BTU input.
(d) Odor. No use shall emit odorous gases or other odorous matter in such quantities as to be offensive at any point on or beyond its lot lines.
(e) Heat. No use shall produce heat detectable without the aid of instruments beyond its lot lines.
(f) Glare. No use shall produce a strong, dazzling light or a reflection thereof beyond its lot lines.
(g) Storage and Waste Disposal.
(1) No highly flammable or explosive liquids, solids or gases shall be stored in bulk above the ground, except tanks or drums of fuel directly connected with energy devices or heating appliances located and operated on the same lot as the tanks or drums of fuel.
(2) All outdoor storage facilities for fuel, raw materials and products, and all fuel, raw materials and products stored outdoors, shall be enclosed by an approved safety fence.
(3) No materials or wastes shall be deposited upon a lot in such form or manner that they may be transported off the lot by natural causes or forces, nor shall any substance which can contaminate a stream or watercourse or otherwise render such stream or watercourse undesirable as a source of water supply or recreation, or which will destroy aquatic life, be allowed to enter any stream or watercourse.
(4) All materials or wastes which might cause fumes or dust, or which constitute a fire hazard, or which may be edible or otherwise attractive to rodents or insects, shall be stored outdoors only if enclosed in containers which are adequate to eliminate such hazards.
(h) Floodways. Permitted uses in any district shall not encroach upon the relatively flat land adjoining watercourses of the Cuyahoga River and Tinkers Creek drainage areas, and subject to overflow therefrom. No construction, storage, or fill shall be permitted which would cause increase in the height or velocity of floods, downstream damage of properly, pollution of the water course, or health hazards on the premise.
