PERFORMANCE STANDARDS FOR INDUSTRIAL ZONES
Effective on: 1/1/1901
The city may require persons submitting such program to submit subsequent periodic reports on progress in achieving compliance.
Effective on: 1/1/1901
In areas to be used for off-street parking, the parking arrangement and surfacing must likewise have been approved of for the development of such tract as a permitted use. Any landscaped areas shall be properly maintained thereafter in a sightly and well kept condition. Parking areas shall likewise be maintained in good condition. Any areas left in a natural state shall be properly maintained in a well kept condition.
In the I-1 Zone, the sound pressure of noise radiated from any activity shall not exceed the values given in Table 15-3 of this section in any octave band frequency at any point on or beyond any lot line. If the IP or I-1 Zones adjoins a residential zone, the maximum sound pressure level at any point on the district boundary shall be reduced by six (6) decibels from the maximum listed in Table 15-3.
In the I-2, I-3, I-4, and I-5 Zones, the sound pressure of noise radiated from any activity shall not exceed the value given in Table 15-3 of this section in any octave band frequency at any point on or beyond the nearest district boundary. If an I-2 Zone adjoins a residential district, the maximum sound pressure shall be reduced by six (6) decibels from the maximum listed in Table 15-3 of this section.
In all districts, industrial noise shall be muffled so as not to become objectionable due to intermittence, beat, frequency, or shrillness.
