The words "shall" and "must" are mandatory; the words "may" and "should"
are permissive. These definitions do not necessarily reflect the definitions
contained in pertinent regulations or statutes, and are intended for
this chapter only.
Activities associated with agriculture such as agricultural
cultivation, agricultural operation, and animal heavy use areas. This
includes the work of producing crops including 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.
A landowner, developer, or other person who has filed an
application to the Borough for approval to engage in any regulated
activity at a project site in the Borough.
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:
"structural" or "nonstructural." In this chapter, nonstructural BMPs
or measures refer to operational and/or behavior-related practices
that attempt to minimize the contact of pollutants with stormwater
runoff, whereas structural BMPs or measures are those 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.

and enforce all or a portion of the regulations promulgated under
25 Pa. Code Chapter 102.
A structure which carries surface water through an obstruction.
An impoundment structure regulated by the Pennsylvania DEP [25 Pa.Code] Chapter 105 regulations.
The Pennsylvania Department of Environmental Protection.
The magnitude and temporal distribution of precipitation
from a storm event measured in probability of occurrence (e.g., a
five-year storm) and duration (e.g., 24 hours) used in the design
and evaluation of stormwater management systems. Also see "return
period."
A structure designed to retard stormwater runoff by temporarily
storing and releasing the runoff at a predetermined rate.
The volume of runoff that is captured and released into the
waters of the Commonwealth at a controlled rate.
See "project site."
An unstabilized land area where an earth disturbance activity
is occurring or has occurred.
The Pennsylvania DEP Erosion and Sedimentation Control Manual,
as amended and updated.
A construction or other human activity which disturbs the
surface of the land, including, but not limited to, clearing and grubbing;
grading; excavations; embankments; road maintenance; building construction;
and the moving, depositing, stockpiling, or storing of soil, rock,
or earth materials.
The natural process by which the surface of the land is worn
away by water, wind, or chemical action.
The combined process of water surface evaporation, soil moisture
evaporation, and plant transpiration.
The dominant land cover during the five-year period immediately
preceding a proposed regulated activity.
Federal Emergency Management Agency.
Any land area susceptible to inundation by water from any
natural source or delineated by applicable FEMA maps and studies as
being a special flood hazard area.
The channel of the watercourse and those portions of the
adjoining floodplains that are reasonably required to carry and discharge
the 100-year flood. Unless otherwise specified, the boundary of the
floodway is as indicated on maps and flood insurance studies provided
by FEMA. In an area where no FEMA maps or studies have defined the
boundary of the 100-year floodway, it is assumed, absent evidence
to the contrary, that the floodway extends from the stream to 50 feet
from the top of the bank of the stream.
Planning and activities necessary for the management of forestland.
These include conducting a timber inventory, preparation of forest
management plans, silvicultural treatment, cutting budgets, logging
road design and construction, timber harvesting, site preparation,
and reforestation.
Systems and practices that use or mimic natural processes
to infiltrate, evapotranspire, or reuse stormwater on the site where
it is generated.
Infiltration rates of soils vary widely and are affected
by subsurface permeability as well as surface intake rates. Soils
are classified into four HSGs (A, B, C, and D) according to their
minimum infiltration rate, which is obtained for bare soil after prolonged
wetting. The NRCS defines the four groups and provides a list of most
of the soils in the United States and their group classification.
The soils in the area of the development site may be identified from
a soil survey report that can be obtained from local NRCS offices
or conservation district offices. Soils become less pervious as the
HSG varies from A to D (NRCS 1,2).
Any area covered by a structure, paving, or other human-made
cover which has a coefficient of runoff of 0.65 or greater, as determined
by the Borough Engineer.
Repair or replacement which uses the same or similar materials
in the same location.
Water flowing downward through the ground surface.
A type of topography or landscape characterized by surface
depressions, sinkholes, rock pinnacles/uneven bedrock surface, underground
drainage, and caves. Karst is formed on carbonate rocks, such as limestone
or dolomite.
Inclusive of any or all of the following meanings:
The improvement of one lot or two or more contiguous lots, tracts,
or parcels of land for any purpose involving a group of two or more
buildings or 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;
Any subdivision of land;
Development in accordance with Section 503(1.1) of the PA Municipalities
Planning Code.
A line provided on the E and S plan or SWM plan that indicates
the total area to be disturbed over the life of the project.
The ratio of impervious area draining to a stormwater management
facility to the area of the stormwater management facility itself.
Site design approaches and small-scale stormwater management
practices that promote the use of natural systems for infiltration,
evapotranspiration, and reuse of rainwater. LID can be applied to
new development, urban retrofits, and revitalization projects. LID
utilizes design techniques that infiltrate, filter, evaporate, and
store runoff close to its source. Rather than rely on costly large-scale
conveyance and treatment systems, LID addresses stormwater through
a variety of small, cost-effective landscape features located on-site.

of a twenty-five-year storm occurring in any one year is 0.04 (i.e.,
a 4% chance).
A permanent area of trees and shrubs located adjacent to
streams, lakes, ponds and wetlands.
Any part of precipitation that flows over the land.

street or easement of access or any residential dwelling, shall be
exempted.
