industrial employee parking, educational facilities, churches.
(b)
All future amendments to the recommended practices

B.
Control of nuisance and disabling glare.
(1)
All outdoor lighting, whether or not required by this
article, on private, residential, commercial, industrial, municipal,
recreational or institutional property shall be aimed, located, designed,
fitted and maintained so as not to present a disabling glare hazard
to drivers or pedestrians, or a nuisance glare concern to neighboring
properties.
(2)
Directional fixtures such as floodlights, spot lights
and sign lights shall be installed or aimed so that they do not shine
directly into the window of a neighboring residence, directly into
a roadway, or skyward.
(3)
Unless otherwise permitted by the Board of Supervisors:
(a)
Streetlighting shall be controlled by photocells
for dusk to dawn operation;
(b)
Area lighting shall be controlled in the following
manners:
[1]
Except for all-night safety or security lighting
uses, all area lighting shall be controlled by automatic switching
devices such as timers and/or motion detectors, to extinguish offending
sources between 11:00 p.m. and dawn, to mitigate glare and skylighting
consequences.
[2]
Where all-night safety or security lighting
is to be provided, the intensity levels of said lighting shall not
exceed 25% of the levels normally permitted by this article.
(c)
Fixtures used for architectural lighting, e.g.,
facade, feature and landscape lighting, shall be aimed so as not to
project their output beyond the objects intended to be illuminated
and shall be extinguished between the hours of 11:00 p.m. and dawn.
(4)
Vegetation screens shall not be employed to serve
as the primary means for controlling glare. Rather, such control shall
be achieved primarily through the use of sharp cutoff fixtures, the
appropriate application of mounting height, wattage, aiming angle,
fixture placement and fixture design, etc. and the additions of shields
and baffles as necessary.
(5)
The amount of illumination projected onto a residential
use from another property shall not exceed 0.1 vertical footcandle
at the property line.
(6)
Externally illuminated signs shall be lighted by fixtures
mounted at the top of the sign and aimed down rather than by fixtures
mounted at the bottom of the sign and aimed up.
C.
Installation:
(1)
Electrical feeds to lighting standards shall run underground,
not overhead.
(2)
Lighting standards in public parking areas shall be
placed a minimum of five feet outside the paved area, or five feet
behind tire-stops locations; or on reinforced concrete pedestals at
least 30 inches high above the pavement, or by other acceptable protective
means.
(3)
Fixtures meeting IESNA "cutoff" criteria shall not
be mounted in excess of 20 feet above finished grade. Fixtures not
meeting IESNA "cutoff" criteria shall not be mounted in excess of
15 feet above finished grade except as specifically approved by the
Board of Supervisors.
D.
Maintenance. Lighting fixtures shall be maintained
so as to always meet the requirements of this article.
Lighting plans submitted to the municipality for review and
approval shall include a layout of the proposed fixture locations;
iso-footcandle plots that demonstrate adequate intensities and uniformity;
and manufacturer's catalog cuts that present a description of the
equipment, including glare reduction devices, lamps, switching devices,
mounting heights and mounting methods proposed. Illumination intensities
shall be plotted on a 10 feet by 10 feet grid. All proposed development
plans shall, at the time of preliminary plan submittal, include lighting
plans indicating proposed placement of all lighting fixtures incorporated
with the above referenced specifications. The lighting plans shall
also provide an engineering detail of fixtures, manufacturer, model,
and installation of same.
