[Ord. 585, 9/12/2011]
ACCELERATED EROSION
The removal of the surface of the land through the combined
action of human activity and natural processes at a rate greater than
would occur because of the natural process alone.
AGRICULTURAL ACTIVITIES
Activities associated with agriculture such as agricultural
cultivation, agricultural operation, and animal heavy use areas. This
includes the work of producing crops, tillage, land clearing, plowing,
disking, harrowing, planting, harvesting crops, or pasturing and raising
of livestock and installation of conservation measures. Construction
of new buildings or impervious area is not considered an agricultural
activity.
ALTERATION
As applied to land, a change in topography as a result of
the moving of soil and rock from one location or position to another;
changing of surface conditions by causing the surface to be more or
less impervious; land disturbance.
APPLICANT
A landowner, developer, or other person who has filed an
application for approval to engage in any regulated activities at
a project site within the Borough.
BEST MANAGEMENT PRACTICES (BMPs)
Activities, facilities, designs, measures or procedures used
to manage stormwater impacts from regulated activities, to meet state
water quality requirements, to promote groundwater recharge and to
otherwise meet the purposes of this chapter. Stormwater BMPs are commonly
grouped into one of two broad categories or measures: "non-structural"
or "structural." "Non-structural" BMPs are measures referred to as
operational and/or behavior-related practices that attempt to minimize
the contact of pollutants with stormwater runoff whereas "structural"
BMPs are measures that consist of a physical device or practice that
is installed to capture and treat stormwater runoff. "Structural"
BMPs include, but are not limited to, a wide variety of practices
and devices, from large-scale retention ponds and constructed wetlands,
to small-scale underground treatment systems, infiltration facilities,
filter strips, low impact design, bioretention, wet ponds, permeable
paving, grassed swales, riparian or forested buffers, sand filters,
detention basins, and manufactured devices. "Structural" stormwater
BMPs are permanent appurtenances to the project site.

HYDROLOGIC SOIL GROUP (HSG)
Infiltration rates of soils vary widely and are affected
by subsurface permeability as well as surface intake rates. Soils
are classified into one of four HSG (A, B, C, and D) according to
their minimum infiltration rate, which is obtained for bare soil after
prolonged wetting. The Natural Resource Conservation Service (NRCS)
of the U.S. Department of Agriculture defines the four groups and
provides a list of most of the soils in the United States and their
group classification.
IMPERVIOUS SURFACE (IMPERVIOUS AREA)
A surface that prevents the infiltration of water into the
ground. Impervious surfaces (or areas) include, but are not limited
to: roofs, additional indoor living spaces, patios, garages, storage
sheds and similar structures, parking or driveway areas, and any new
streets and sidewalks. Any surface areas proposed to initially be
gravel or crushed stone shall be assumed to be impervious surfaces.

of two or more buildings, or (2) the division or allocation of land
or space between or among two or more existing or prospective occupants
by means of, or for the purpose of streets, common areas, leaseholds,
condominiums, building groups, or other features; (B) any subdivision
of land; (C) development in accordance with § 503(1.1) of
the Pennsylvania Municipalities Planning Code, 53 P.S. § 10503(1.1).

LOW IMPACT DEVELOPMENT (LID)
An approach to land development that uses various land planning
and design practices and technologies to simultaneously conserve and
protect natural resource systems and reduce infrastructure costs.
LID still allows land to be developed, but in a cost-effective manner
that helps mitigate potential environmental impacts.
