B.
Performance Standards.
1.
Vibration. Every use shall be so operated that the maximum ground vibration generated is not perceptible without instruments at any point on the lot line of the lot on which the use is located.
2.
Noise. Every use shall be so operated that the pressure level of sound or noise generated, measured in decibels, shall not exceed, at any point on the lot line, the maximum decibel levels for the designed octave band as set forth in the following table for the appropriate area:
Octave Band Cycles Per Second | Maximum Permitted Sound Pressure Level in Decibels Within or Adjacent to "R" Residential Districts | Within All Other Areas |
|---|---|---|
0 to 75 | 72 | 79 |
75 to 150 | 67 | 74 |
150 to 300 | 59 | 66 |
300 to 600 | 52 | 59 |
600 to 1,200 | 46 | 53 |
1,200 to 2,400 | 40 | 47 |
2,400 to 4,800 | 34 | 41 |
Above 4,800 | 32 | 39 |
3.
Odor. Every use shall be so operated that no offensive or objectionable odor is emitted in accordance with the requirements of St. Louis County Health Department Ordinance 3347, 1964, or as amended.
4.
Smoke. Every use shall be so operated that no smoke from any source shall be emitted that exceeds the emission levels in the requirements of St. Louis County Health Department Ordinance 3345, 1964, or as amended.
5.
Toxic gases. Every use shall be so operated that there are no emissions of toxic, noxious or corrosive fumes or gases which exceed the emission levels in the requirements of St. Louis County Health Department Ordinance 3347, 1964, or as amended.
6.
Emission of dirt, dust, fly ash, and other forms of particulate matter. The emission of dirt, dust, fly ash, and other forms of particulate matter shall not exceed the emission levels in the requirements of St. Louis County Health Department Ordinance 3347, 1964, or as amended.
7.
Radiation. Every use shall be so operated that there is no dangerous amount of radioactive emissions in accordance with the standards of the Federal Radiation Council.
8.
Glare and heat. Any operation producing intense glare or heat shall be performed in an enclosure in such a manner so as to be imperceptible along any lot line without instruments.
9.
Lighting. Illumination levels shall be measured with a photoelectric photometer having a spectral response similar to that of the human eye, following the standard spectral luminous efficiency curve adopted by the International Commission on Illumination. All lighting shall comply with the following standards:
a.
All illumination structures, except for approved streetlights, shall be so arranged to prevent direct light from being cast upon any adjacent property or public right-of-way and to prevent glare or other objectionable problems to surrounding areas.
b.
No light fixture shall have any blinking, flashing, or fluttering lights or other illuminating device which has a changing light intensity, brightness, or color, nor shall any beacon or spotlights be permitted.
c.
Neither the direct nor reflected light from any light fixture shall create a disabling glare causing traffic hazards to motor vehicle operators on public thoroughfares.
d.
Any non-residential, off-street parking or loading area in use at night shall contain a system of lighting to provide an adequate standard of at least one footcandle of illumination over the area of the parking area to be used.
e.
All lighting shall be arranged to deflect, shade, and focus light away from adjacent properties, including public rights-of-way. Lighting shall be designed so as not to create more than one footcandle of illumination at any residentially zoned property boundary, or more than five footcandles at any commercially zoned property boundary.
f.
Display lot lighting shall be turned off within thirty (30) minutes after closing of the business. Full illumination of the display lot shall not be permitted after 11:00 P.M. Only non-residential security lighting shall be used after 11:00 P.M.
g.
Light fixtures used to illuminate objects mounted on a pole, platform, or pedestal shall not use a spotlight that will extend beyond the illuminated object. Uplighting of these structures shall cease after 11:00 P.M., except for uplighting of the American flag, or unless otherwise regulated.
h.
All other outdoor light fixtures lawfully installed prior to and operable on the effective date of this Chapter are exempt from these requirements unless:
(1)
Existing outdoor lighting fixtures are replaced, removed, or reinstalled; or
(2)
Existing outdoor lighting systems are judged to be "intolerable" due to excessive, objectionable light emission as assessed by the Director of Economic Development; or if the emissions cause unsafe or hazardous conditions. Upon written notice by the Administrator, the owner of such lighting system will have thirty (30) days to comply with the provisions as set forth in this Section. A thirty-day extension may be granted by the Director of Economic Development.
C.
The Director of Economic Development may require a special inspection to ascertain compliance with this Section.
D.
Any addition, modification, or change in any regulations, Code ordinance, or other standard referred to in these zoning performance standards shall become a part of these regulations.
