Zoning Districts, as well as in mixed-use overlays, and all land uses
requiring a conditional use permit within any residential district.
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

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.
