It is the intent of the standards of this section to ensure a high quality working environment and available sites for industrial and business firms whose functional and economic needs require protection from the adverse effects of noise, odors, vibration, glare or high-intensity illumination, and other nuisances.
A. 
Noise. The maximum allowable exterior noise level of any use shall not exceed the levels established by Municipal Code Chapter 11.96.
B. 
Vibration. All uses shall be so operated as not to generate vibration discernible without instruments by the average person while on or beyond the lot upon which the source is located or within an adjoining enclosed space if more than one establishment occupies a structure. Vibration caused by motor vehicles, trains, and temporary construction or demolition work is exempted from this standard.
C. 
Particulate Matter and Air Contaminants. In addition to compliance with the air pollution control authorities' standards, all uses shall be operated so as not to emit particulate matter or air contaminants which are readily detectable without instruments by the average person while on the lot containing such uses.
D. 
Odor. All uses shall be operated so as not to emit matter causing unpleasant odors which are perceptible to the average person while within or beyond the lot containing such uses.
E. 
Humidity, Heat and Glare. All uses shall be operated so as not to produce humidity, heat, glare, or high-intensity illumination which is perceptible without instruments by the average person while on or beyond the lot containing the use.
(Ord. 80 Art. V(O)(2), 1984; Ord. 263 § 10, 1989; Ord. 791 § 1, 2017; Ord. 862 § 2, 2022)
It is the intent of the standards of this section to provide for uses whose operational needs may produce noise, vibration, particulate matter, and air contaminants, odors, or humidity, heat, and glare which cannot be mitigated sufficiently to meet the Class A standards. The standards are so designed to protect uses on adjoining sites from effects which could adversely affect their functional and economic viability.
A. 
Noise. The maximum allowable noise level of any use shall not exceed the levels established by Municipal Code Chapter 11.96.
B. 
Vibration. All uses shall be so operated as not to generate vibration discernible without instruments by the average person while on or beyond the lot upon which the source is located or within an adjoining enclosed space if more than one establishment occupies a structure. Vibration caused by motor vehicles, trains, and temporary construction or demolition work is exempted from this standard.
C. 
Particulate Matter and Air Contaminants. In addition to compliance with the air pollution control authorities' standards, all uses shall be operated so as not to emit particulate matter or air contaminants which are readily detectable without instruments by the average person beyond any lot line of the lot containing such uses.
D. 
Odor. All uses shall be operated so as not to emit matter causing unpleasant odors which are perceptible to the average person beyond any lot line of the lot containing such uses.
E. 
Humidity, Heat and Glare. All uses shall be operated so as not to produce humidity, heat, glare, or high-intensity illumination which is perceptible without instruments by the average person beyond the lot line of any lot containing such uses.
