inch/hour).
4.
(High runoff potential) Soils having very slow infiltration
rates when thoroughly wetted and consisting chiefly of clay soils
with a high swelling potential, soils with a permanent high water
table, soils with a clay pan or clay layer at or near the surface,

stone, and compacted soil shall be considered impervious surface if
they prevent infiltration.
IMPOUNDMENT

runoff and infiltrate it into the ground (in the case of a retention
basin) or release it at a controlled rate (in the case of a detention
basin).

french drains, seepage pits, seepage trench, rain gardens, vegetated
swales, pervious paving, infiltration basins, etc.).

runoff and groundwater discharges.

authorized under the lease to exercise the rights of the landowner,
or other person having a proprietary interest in land.
LIMITING ZONE

is so slowly permeable that it effectively limits downward passage
of effluent. Season high-water tables, whether perched or regional
also constitute a limiting zone.
LINEAMENT
A linear feature in a landscape which is an expression of
an underlying geological structure such as a fault.
LOW-IMPACT DEVELOPMENT (LID)
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.
[Added by Ord. No. 2022-1, 9/13/2022]
MANNING'S EQUATION
An equation for calculation of velocity of flow (e.g. feet
per second) and flow rate (e.g. cubic feet per second) in open channels

Equation assumes steady, gradually varied flow.
MAXIMUM EXTENT PRACTICABLE (MEP)
Applies when the applicant demonstrates to the Borough's
satisfaction that the performance standard is not achievable. The
applicant shall take into account the best available technology, cost
effectiveness, geographic features, and other competing interests
such as protection of human safety and welfare, protection of endangered
and threatened resources, and preservation of historic properties
in making the assertion that the performance standard cannot be met
and that a different means of control is appropriate.
