and State Department of Environmental Conservation standards.
B. Where applicable, sewer system permits are required
prior to issuance of the building permit for any site development.
C. All utilities, exclusive of transformers, will be
placed underground at the time of initial construction. Required utilities
may include water, sewer, telephone, electricity, gas, and wiring
for streetlights.
D. Lighting.
(1) All exterior lights and illuminated signs shall be
designed and located in such a manner as to prevent objectionable
light and glare to spill across property lines. The following horizontal
illumination levels shall be observed. For uses not listed here, the
Planning Board may determine the appropriate horizontal lamination
level referencing the values found in the reference titled "The IESNA
Lighting Handbook" published by the Illumination Engineering Society
of North America. The Planning Board may vary these standards, making
them more or less restrictive, where it finds it to be in the interests
of this chapter and the Town to do so.

(2) Fixtures. A lighting fixture shall be architecturally
compatible with the primary building. Fixtures shall be shielded and
have cutoffs to direct light directly to the ground. This must be
accomplished so that light dispersion or glare does not shine above
a ninety-degree horizontal plane from the base of the fixture. Cutoff
fixtures must be installed in a horizontal position as designed. Flat
lens cutoffs are required. Fixtures shall generally be of dark colors.
Pole-mounted fixtures shall not exceed 20 feet in height.
(3) Vision. Lighting shall not interfere or impair pedestrian
or motorist vision.
(4) Procedure. At the request of the Planning Board, a
use subject to site plan review shall submit a lighting plan describing
the lighting component specifications such as lamps, poles, reflectors
and bulbs. The lighting plan shall show the illumination levels for
the entire site and shall be at a scale consistent with the site plan.
The Planning Board may require specific lighting plans to address
portions of the site, such as parking lots or pedestrian walkways,
for evaluation purposes. The Planning Board may control the hours
of illumination.
No activities shall be permitted which:
A. Emit dangerous radioactivity; or
B. Create electrical disturbance adversely affecting
the operation of any equipment other than that of the creator of such
disturbance.
No vibration shall be permitted which is detectable
without the aid of an instrument at the property line or which may
cause annoyance to a person of reasonable sensitivity.
Development at the site shall take into consideration
that access to the site and the structures must accommodate emergency
vehicles.
In addition to the foregoing, no individual
commercial store or business may exceed 60,000 square feet in size,
inclusive of outdoor display and storage areas. For purposes of this
section, individual stores that have one or more separate building
pads or footprints which are connected to one another by means of
a common walkway shall be considered to be a single store. This section
is not intended to regulate shopping centers, which may exceed 60,000
square feet in total size, provided that no individual store exceeds
60,000 square feet.
Standards for multifamily dwellings shall be
as follows:
A. Sidewalks shall be provided, as appropriate, to connect
the residential units with parking areas, public streets, recreation
areas and other apartment buildings.
B. Buffers shall be used, as appropriate, to separate
the residential units from the recreational areas and to maintain
natural areas between multifamily structures. Buffer strips shall
consist of trees, hedges, dense plantings, earth berms and/or changes
in grade.
C. Landscaping and screening shall conform to the following
minimum standards:
(1) Units shall be sited for maximum preservation of mature
trees (trees of two inches or more in diameter). Where large-diameter
shade trees cannot be preserved, new ones shall be planted to replace
them.
(2) Clear cutting of the site area is to be minimized.
D. Solid waste and recycling receptacles of adequate
capacity shall be provided for the maximum number of residents. Receptacles
shall be screened from view by fencing or landscaping and properly
emptied to prevent odor and unsanitary conditions. The receptacle
shall be designed to prevent the escape of litter and waste.
E. Internal road systems for multifamily developments
shall be in conformance with the following standards:
(1) Double-lane access shall be provided. A road network
with two separate access points may be required where justified by
site and/or traffic conditions.
(2) Internal circulation systems shall be able to accommodate
all service and emergency vehicles and shall provide for year-round
access.
(3) Private roads within a multifamily development shall
conform to Town of Greenwich standards for street design.
Property to be developed for industrial uses
shall be developed in accordance with the following standards:
A. Landscaping and screening shall be provided as follows:
(1) Existing vegetation shall be used to the greatest
extent possible.
(2) Along a property line facing a residential property,
a minimum twenty-foot-wide to fifty-foot-wide buffer strip of evergreen
planting shall be provided to effectively screen a heavy industrial
use. For a light industrial use, the minimum may be reduced to a ten-foot
buffer.
(3) Along road frontage, a twenty-foot-wide buffer of
landscaping shall be provided where appropriate and be designed so
as not to obstruct sight distance at points of access for heavy industrial
use. Landscaping for light industrial uses may be reduced to a ten-foot-wide
buffer.
B. The following off-street loading standards for heavy
industrial uses shall be met by the applicant unless otherwise exempted
by the Planning Board:
(1) There shall be a minimum of one off-street loading
space.
(2) Each off-street loading space shall be at least 15
feet in width and provide adequate access and turning areas.
(3) Any loading dock facing a road front shall be sufficiently
far back from the road to enable the largest permitted tractor-trailer
to maneuver into said loading dock without obstructing traffic.
C. Hazardous material storage must comply with all state
and federal regulations.
(1) Access drives shall be finished with a surface that
will assure that it will be maintained to minimize dust and debris.
Surface materials may include oil and chip, compact gravel or blacktop.
