The words "shall" and "must" are mandatory; the words "may" and "should"
are permissive.
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 Foster Township for approval to engage in any regulated
activity at a project site in Foster Township.
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.
The process of collecting runoff to be managed by a stormwater
BMP.
A conservation district, as defined in Section 3(c) of the
Conservation District Law [3 P. S. § 851(c)] that has the
authority under a delegation agreement executed with DEP to administer
and enforce all or a portion of the regulations promulgated under
25 Pa. Code Chapter 102; refers to the Luzerne Conservation District
unless otherwise noted.
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."
The volume of runoff that is captured and released into the
waters of this commonwealth at a controlled rate.
See "land development."
Any human-induced change to improved or unimproved real estate,
whether public or private, including, but not limited to, land development,
construction, installation, or expansion of a building or other structure,
land division, street construction, drilling, and site alteration
such as embankments, dredging, grubbing, grading, paving, parking
or storage facilities, excavation, filling, stockpiling, or clearing.
An impervious or impermeable surface that is disconnected
from any stormwater drainage or conveyance system and is redirected
or directed to a pervious area, which allows for infiltration, filtration,
and increased time of concentration as specified in Appendix C.1,
Disconnected Impervious Area.[1]
An unstabilized land area where an earth disturbance activity
is occurring or has occurred.
A construction or other human activity which disturbs the
surface of the land, including, but not limited to: grubbing; grading;
excavations; embankments; road maintenance; building construction;
and the moving, depositing, stockpiling, or storing of soil, rock,
or earth materials. The clearing of vegetation without disturbance
of the land shall not be considered an earth disturbance activity.
The natural process by which the surface of the land is worn
away by water, wind, or chemical action.
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. Also includes areas that comprise
Group 13 soils, as listed in Appendix A of the Pennsylvania DEP Technical
Manual for Sewage Enforcement Officers (as amended or replaced from
time to time by DEP).
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.
A porous fabric manufactured from synthetic fiber that is
used to provide separation between different types of media (i.e.,
between soil and stone).
Considered to be impervious when the intended use of the
stone is for transportation purposes, parking areas, construction
areas, trails, or if the gravel is compacted at any time during or
after its placement; landscaping stone is not considered as impervious
area.
Areas where land use or activities generate highly contaminated
runoff, with concentrations of pollutants that are higher than those
that are typically found in stormwater (e.g., vehicle salvage yards
and recycling facilities, vehicle fueling stations, fleet storage
areas, vehicle equipment and cleaning facilities, and vehicle service
and maintenance facilities).
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§ 192-37C and D).
A permanent surface that prevents the infiltration of water
into the ground. Impervious surfaces include, but are not limited
to, streets, sidewalks, pavements, parking lots, driveways, roofs,
and stone patios. See definition of "gravel (crushed stone)" for when
gravel classifies as impervious area.
Movement of surface water into the soil, where it is absorbed
by plant roots, evaporated into the atmosphere, or percolated downward
to recharge groundwater.
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.
See definition of "land development" as defined in Chapter 210, Subdivision and Land Development, of the Code of the Township of Foster.
A land development and construction approach that uses various
land planning, design practices, and technologies to simultaneously
conserve and protect natural resource systems while allowing for necessary
infrastructure improvements associated with land development.
Foster Township, Luzerne County, Pennsylvania.
United States Department of Agriculture's Natural Resources
Conservation Service (previously SCS).
The maximum rate of stormwater runoff from a specific storm
event.

in Foster Township are planned, conducted, or maintained.
Any person licensed by the Pennsylvania Department of State
or otherwise qualified by law to perform the work required by this
chapter.
Any development that requires demolition or removal of existing
structures or impervious surfaces at a site and replacement with new
impervious surfaces. Maintenance activities such as top-layer grinding
and repaving are not considered to be redevelopment unless the resurfacing
results in a discernible change in the existing stormwater runoff
discharge point. Interior remodeling projects and tenant improvements
are also not considered to be redevelopment.
Any earth disturbance activities or any activities that involve the alteration or development of land in a manner that may affect stormwater runoff. The installation of a new stormwater management facility shall be considered a regulated activity of this chapter regardless of the amount of earth disturbance associated with the installation of the facility. See § 192-5 of this chapter for additional detail on regulated activities.
The volume of runoff that is captured and not released directly
into the surface waters of this commonwealth during or after a storm
event.
The average interval, in years, within which a storm event
of a given magnitude can be expected to occur one time. For example,
the twenty-five-year return period rainfall would be expected to occur
on average once every 25 years; or stated in another way, the probability
of a twenty-five-year storm occurring in any one year is 0.04 (i.e.,
a 4% chance).
Any part of precipitation that flows over the land.
Soils or other materials transported by surface water as
a product of erosion.

its condition, design, or construction, conveys, stores, or otherwise
affects stormwater runoff. Typical stormwater management facilities
include, but are not limited to: detention and retention basins, open
channels, storm sewers, pipes, french drains, underground on-lot seepage
pits (dry wells), roof drains, sump pump discharge piping, foundation
drains, and infiltration facilities.
