The performance standards contained herein are
intended to protect both the community at large and proposed uses
from abuse and negative impacts, while encouraging appropriate development
to occur.
Uses permitted in any commercial, employment
and flexible district, and uses accessory thereto, are subject to
the following performance standards and procedures. If the Zoning
Officer or the Zoning Hearing Board has reasonable grounds for believing
that any other use will violate these performance standards, such
use, existing or proposed, shall also be subject to these performance
standards.
The definitions in §
325-5 of this chapter shall apply. In addition, the following words and phrases when used in this article shall, for the purposes of this article, have the meanings respectively ascribed to them in this section, except in those situations where the context clearly indicates a different meaning:
A-WEIGHTED SOUND PRESSURE LEVEL
The sound pressure level as measured on a sound level meter
using the A-weighted network or scale as specified in ANSI S1.4-1983
(R1997) or its successor publication. The level read shall be postscripted
dB(A) or dBA.
DECIBEL
A unit which describes the sound pressure level or intensity
of sound. The sound pressure level in decibels is 20 times the logarithm
to the base 10 of the ratio of the pressure of the sound in microbars
to a reference pressure of 0.0002 microbar, abbreviated dB.
DEVICE
Any mechanism which is intended to or which actually produces
a noise when operated or handled.
DISPLACEMENT
The single amplitude displacement of the vibration in inches.
EMERGENCY WORK
Work made necessary to restore property to a safe condition
following a public calamity or work required to protect persons or
property from immediate exposure to danger, including work performed
by public service companies when emergency inspection, repair of facilities
or restoration of services is required for the immediate health, safety
or welfare of the community.
ENVIRONMENTAL PROFESSIONAL
A person possessing sufficient education, training, related
project experience and certifications necessary to evaluate a proposed
use in accordance with the environmental performance standards set
forth in this article and having the ability to develop opinions and
conclusions regarding the environmental impacts of the proposed use.
An individual's status as an environmental professional may be limited
to the type of assessment to be performed or to specific segments
of the assessment for which the professional is responsible. In conjunction
with the sealing of the environmental impact statement (EIS), the
registered professional engineer who is in responsible charge of preparing
the EIS shall provide certification that the environmental professionals
involved in preparing the EIS under his/her charge are qualified in
their specific fields.
ENVIRONMENTAL IMPACT STATEMENT
A statement of environmental impact which addresses methods
of compliance for each and every environmental performance standard
listed in the Flexible Development District Ordinance.
EQUIVALENT SOUND LEVEL (LEQ)
The constant sound level that, in a given situation and time
period, conveys the same sound energy as the actual time-varying A-weighted
sound pressure level.
MOTOR VEHICLE
Any vehicle which is self-propelled, except one which is
propelled solely by human power or by electric power obtained from
overhead trolley wires, but not operated upon rails.
NOISE DISTURBANCE
Any unnecessary sound which annoys, disturbs or perturbs
reasonable persons with normal sensitivities or any unnecessary sound
which reasonably may be perceived to injure or endanger the comfort,
repose, health, peace or safety of any person.
OCTAVE BAND ANALYZER
An instrument to measure the octave band composition of a
sound by means of a bandpass filter. It shall meet the specifications
of the American National Standards Institute publications S14-1983
(R1997), S1.6-1984 (R1997) and S1.11-1986 (R1998), or their successor
publications.
PARTICLE VELOCITY
The distance a particle travels in inches per second and
is computed using the following formula with the elements defined
in this section: PV = 6.28 F x D.
PARTICLE VELOCITY MEASUREMENT
The velocity measured in three mutually perpendicular directions.
The maximum allowable peak particle velocity shall apply to each of
the three measurements.
POWERED MODEL VEHICLES
Any mechanically powered vehicle, either airborne, waterborne
or land borne, which is not designed to carry persons or property,
including but not limited to model airplanes, boats, cars and rockets.
PROPERTY BOUNDARY
Any point along the property line from ground level to any
point above the ground along a vertical plane.
SOUND
A temporal and spatial oscillation in pressure, or other
physical quantity, in a medium with internal forces that causes compression
and rarefaction of that medium and which propagates at finite speed
to distant points.
SOUND LEVEL METER
An instrument to measure sound pressure levels which shall
meet or exceed performance standards for a Type Two meter as specified
by the American National Standards Institute S1-4-1983 (R1997) or
its successor publications.
SOUND PRESSURE
The instantaneous difference between the actual pressure
and the average or barometric pressure at a given point in space.
STATIONARY NOISE SOURCE
Any equipment or facility, fixed or movable, capable of emitting
sound beyond the property boundary of the property on which it is
used.
VIBRATION
An oscillatory motion of solid bodies of deterministic of
random nature described by displacement, velocity or acceleration
with respect to a given reference point.
VIBRATION FREQUENCY
The time rate of repetition of a periodic phenomenon in cycles
per second and calculated as the reciprocal of the period.
No heat from any use shall be sensed at any
property line to the extent of raising the ambient temperature of
air or materials more than one Fahrenheit degree.
All earthmoving activities regardless of the
extent of disturbance shall be conducted in such a way as to minimize
erosion and resulting sedimentation. Any person, landowner, business
or corporation involved in earthmoving activities shall develop, implement
and maintain erosion and sediment control measures. At a minimum,
the person, landowner, business or corporation shall meet the standards
of the York County Conservation District and Chapter 102 of Title
25, Pa. Code, Rules and Regulations of the Pennsylvania Department
of Environmental Protection, as amended. A complete explanation is
available in DEP's publication "Erosion and Sediment Pollution Control
Program Manual," which is available through the local conservation
district office.
Standards for air quality have been established by the Commonwealth of Pennsylvania and U.S. Environmental Protection Agency. In order to minimize overlapping regulations, the Township adopts these standards as its own. Therefore, all operations, activities and uses shall be in compliance with the standards contained in the following: Commonwealth of Pennsylvania Air Pollution Control Act, Title 25, Pa. Code, Chapters
121 through 143 and the Code of Federal Regulations, Title 40, Subchapter C.
