[Ord. No. 2023-1, 1/11/2023]
For the purposes of this chapter, the following words, terms
and phrases have the meanings indicated herein:
AGRICULTURAL ACTIVITY
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.
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;
also, the changing of surface conditions by causing the surface to
be more or less impervious; land disturbance.
APPLICANT
Any landowner, person, partnership, association, corporation
or other for-profit or nonprofit entity, or any responsible person
therein or agent thereof, who has filed an application with the municipality
for approval to engage in any of the regulated activities of this
chapter within the municipality.
BEST MANAGEMENT PRACTICE (BMP)
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, 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 project sites.

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. "Luzerne County Conservation District" and
"Luzerne Conservation District" shall have the same meaning.

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). (NOTE: See § 1001, Subsections
3 and 4, of this chapter.)

initially or cumulatively.
LOW-IMPACT DEVELOPMENT
Site design approaches and small-scale stormwater management
practices that promote the use of natural systems for infiltration,

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.
