After the effective date of this ordinance, any use established or changed to, and any building, structure, or tract of land, developed, constructed, or used for any permitted or permissible principal or accessory use in the IP Zone, shall comply with all of the performance standards herein set forth for the district involved. If any existing use, or building, or other structure is extended, enlarged, or reconstructed, the performance standards for the district involved shall apply with respect to such extended, enlarged, or reconstructed portion, or portions, of such use, or building, or other structure.
Effective on: 1/1/1901
Except as otherwise specified herein, compliance with the provisions of this article of the ordinance shall be according to the following time schedule:
The city may require persons submitting such program to submit subsequent periodic reports on progress in achieving compliance.
Effective on: 1/1/1901
The sum total of the effects of concurrent operations on two (2) or more lots should not be greater or more offensive to the senses than the standards contained herein. Compliance with the provision of these performance standards by single or mutual changes in operational levels, scheduling of operations, and other adjustments is permitted.
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.
