All uses in all districts shall comply with all the performance standards listed in Article IV.
The developer shall determine the presence of
environmental or natural features on the site and shall meet the following
standards of environmental protection. Site alterations, regrading,
filling or clearing of vegetation prior to submission of the plans
for development shall be a violation of this chapter.
A.
Floodplains. All such lands are identified on the
Zoning Map. See Article VIII, Floodplain District, for specific regulations.[1]
B.
Slopes. In areas of slopes, i.e., those above 8%,
the following standards shall apply:
(1)
Eight percent to 15%: No more than 60% of such areas
shall be developed and/or regraded or stripped of vegetation.
(2)
Fifteen percent to 25%: No more than 40% of such areas
shall be developed and/or regraded or stripped of vegetation.
(3)
Twenty-five percent or more: No more than 20% of such
areas shall be developed and/or regraded or stripped of vegetation.
C.
Areas of moderate to high landslide susceptibility
produced by the influence of natural and/or man-related activity.
Plans for development within these areas must be submitted by a professional
engineer or landscape architect and approved by the governing body.
D.
Woodlands. No more than 50% of any woodland, exclusive
of public streets and rights-of-way, may be cleared or developed.
The remaining 50% shall be maintained as permanent open space.
E.
Ponds or watercourses. These areas shall be left as
permanent open space. No development, filling, piping or diverting
shall be permitted except for required roads. Any soil disturbance
or removal of vegetation within 100 feet of such ponds or watercourses
is prohibited except where primary access is required. In such instances,
additional environmental studies may be required at the discretion
of the Bell Acres Planning Commission or Bell Acres Borough Council.
For purposes of this section, a watercourse shall be defined as any
stream or stream bed that has a contributory watershed of at least
10 acres, while a pond is defined as containing at least 10,000 square
feet of surface, measured at the high water mark.

Description of the equipment, including luminaire catalog cuts,
photometrics, glare-reduction devices, lamps, control devices, mounting
heights and mounting methods proposed.
(2)
For all land development plans proposing recreational use lighting,
in addition to the above content, the following shall also be provided:
(a)
Plan views containing a layout of the facility and showing pole
locations and the location of residences on adjoining properties.
(b)
Elevation views containing pole and luminaire mounting heights,
horizontal and vertical aiming angles and luminaire arrays for each
pole location.
(c)
Elevations containing initial vertical illuminance plots at
the boundary of the site, taken at a height of five-foot line of sight.
(d)
Elevations containing initial vertical illuminance plots on
the windowed facades of all residences facing and adjacent to the
facility. Such plots shall demonstrate compliance with the light trespass
and glare control requirements of this section.
(e)
Proposed frequency of the use of the facility during hours of
darkness on a month-by-month basis and proposed time when the sports
lighting will be extinguished.
(f)
A narrative describing the measures proposed to achieve minimum
off-site disturbance.
(g)
Documentation sufficient to demonstrate to the reasonable satisfaction
of the Borough Engineer that the proposed mounting height of the recreational
use lighting is the minimum necessary to adequately and safely light
the recreational use proposed to be lighted.
The ambient sound level of any operation (other
than the operation of motor vehicles or other transportation facilities,
operations involved in the construction or demolition of structures,
emergency alarm signals or time signals) shall not exceed the decibel
levels listed in the tables shown.
A.
The sound pressure level or ambient level is the all-encompassing
noise associated with a given environment, being a composite of sounds
from any source, near and far. For the purpose of this chapter, "ambient
noise level" is the average over 15 minutes of the alleged offensive
noise, excluding random or intermittent noises. Averaging may be done
by instrument analysis in accordance with American National Standard
S.13-1971, or may be done manually as follows:
(1)
Observe a sound-level meter for five seconds and record
the best estimate of central tendency of the indicator needle and
the highest and lowest indications.
(2)
Repeat the observations as many times as necessary
to provide that observations be made at the beginning and at the end
of the fifteen-minute period and that there shall be at least as many
observations as there are decibels between the lowest low indication
and the highest high indication.
(3)
Calculate the arithmetical average of the observed
central tendency indications.
B.
It shall be unlawful for any person to operate any
fixed machinery or equipment or similar mechanical device in any manner
so as to create any noise which would cause the noise level measured
at the property line of the property affected by the noise emission
to be beyond permitted levels.
(1)
Noise limits shall not exceed the following:

two zoning districts, the lower sound level shall apply.
No discharge at any point into any private sewage
disposal system or stream or into the ground of any materials in such
a way or in such nature or temperature as can contaminate any water
supply or otherwise cause the emission of dangerous or objectionable
elements or the accumulation of solid wastes conducive to the breeding
of rodents or insects is permitted.
No activities producing heat, cold, dampness
or movement of air are permitted which shall produce any material
effect on the temperature, motion or humidity of the atmosphere at
the lot line or beyond.
No use shall cause earth vibrations or concussions
in excess of the standards outlined below, with the exception of that
vibration produced as a result of construction activity. The standards
below are as set forth in the Table of Frequency Amplitude Relations.
Vibration shall be expressed as displacement in inches and shall be
measured with a standard three-component measuring system, which is
a device for recording the intensity of any vibration in three mutually
perpendicular directions.
