storing the runoff and releasing it at a predetermined rate. A detention
pond may be designed to drain completely after a storm event (dry

(wet pond).
A person or persons, partnership, association, corporation
or other entity, or any responsible person therein or agent thereof,
who undertakes the activities covered by this Part.
A recorded agreement of right-of-way granted, but not dedicated,
for limited use of private land for a public or quasi-public purpose,
identified on the final plan, and within which the owner of the property
shall not erect any permanent structures, but shall have the right
to make any other use of the land which is not inconsistent with the
rights of the grantee.
The removal of soil, stone and other surface materials by
the action of natural elements.
A floodplain or flood hazard area is that land, within the
Township, adjoining any watercourse subject to a one-hundred-year
recurrence interval flood as delineated by a study prepared by any
federal, state or county agency; a registered professional engineer
experienced in the preparation of hydrological and hydraulic studies
and the determination of flood boundary lines; or the area denoted
as having alluvial soils on the most recent soil survey of the Soil
Conservation Service, United States Department of Agriculture.
A large rectangular box of heavy gage wire mesh which holds
large cobbles and boulders. Used in streams and ponds to change flow
patterns, stabilize banks or prevent erosion.
The basic or fundamental rock stratigraphic unit in the local
classification of rocks, consisting of a body of rock (usually a sedimentary
stratum or strata but also igneous or metamorphic) generally characterized
by some degree of internal lithologic homogeneity or distinctive lithologic
features (such as chemical composition, structures, textures, gross
aspect of fossils or time of deposition.) Typically used for mapping
the geology of an area.
A rock stratigraphic unit which is subordinate (a subject)
of a formation. This unit is not necessarily mappable and is usually
a unified subdivision of local extent that may or may not be contained
in more than one foundation.
A body of standing water occurring in a sinkhole or closed
depression of a Karst region that is usually visible after sufficient
precipitation has occurred. They may form from slow permeability of
soils, rises in the water table or the development of a natural liner
of slow permeable clays or soils.
The act the excavating and/or filling land for the purposes
of changing natural slope.
Replenishment of existing natural underground water supplies.
Impermeable surfaces, such as pavement on rooftops, which
limits the infiltration of water into the soil, as outlined in Table
A-2 of Appendix A, § I.
A surface which limits the penetration of water into the
ground.
A structure designed to direct runoff into the ground, such
as french drains, seepage pits or seepage trenches.
A type of topography that is formed over limestone, dolomite
or gypsum by bedrock solution and that is characterized by closed
depressions or sinkholes, caves, and underground drainage (from AGI,
Glossary of Geology, 1972).
Any activity involving grading, tilling, digging or filling
of ground or stripping of vegetation or any other activity which causes
land to be exposed to erosion.
A device used to spread out stormwater runoff uniformly over
the ground surface as sheet flow (i.e., not through channels). The
purpose of level spreaders are to prevent concentrated, erosive flows
from occurring, and to enhance infiltration.
Straight or gently curved, lengthy features frequently expressed
topographically as depressions or lines on the earth's surface.
They can be more easily observed at a height of 100 meters or more
and are usually found by researching aerial photographs or satellite
photography. They are usually located in areas of faulting or in dense
jointing along some rock stratigraphy.
An incised or paved channel from inlet to outlet in a dry
basin which is designed to carry low runoff flows and/or base flow
directly to the outlet without detention.
The Township of Ralpho, Northumberland County, Pennsylvania.
The maximum rate of flow of water at a given point and time
resulting from a storm event.
Act of 1990, December 19, P.L. 1343, as amended, 53 P.S.
§ 10101 et seq.
An individual registered in and licensed by the State of
Pennsylvania including, for the purposes of this Part, land surveyors,
landscape architects, architects and engineers.
A basin in which the runoff from a given flood event is stored
and is not discharged into the downstream drainage system during the
flood event.
A combination of large stone, cobbles and boulders used to
line channels, stabilize banks, and reduce runoff velocities.
Soil Conservation Service, U.S. Department of Agriculture.
The process by which mineral or organic matter is accumulated
or deposited by the movement of water.
A barrier, dam, retention or detention basin located and
designed to retain rock, sand, gravel, silt or other water transported
material.
Runoff which flows over the ground surface as a thin, even
layer, not concentrated in a channel. Flow depth is generally 0.1
foot or less.
A localized, gradual or rapid sinking of the land surface
to a variable depth, occurring in areas of carbonate bedrock; generally
characterized by a roughly circular outline, a distant breaking of
the ground surface and downward movement of soil into bedrock voids.
The area inundated by the one-hundred-year, twenty-four-hour
storm, assuming no drainage from the sinkhole or closed depression
based upon anticipated runoff volumes with maximum development permitted
by zoning within the catchment area or area draining to the sinkhole.
A method of runoff computation developed by SCS, and found
in its publication "Urban Hydrology for Small Watersheds," Technical
Release No. 55, as revised.
A system of pipes or other conduits which carries intercepted
surface runoff, street water and other wash water or drainage, excluding
domestic sewage and industrial wastes.
The drainage runoff from the surface of the land resulting
from precipitation, snow or ice melt.
Tabular or sheet-like mass, distinct layers of homogenous
or gradational sedimentary material (consolidated rock or unconsolidated
earth) of any thickness, visually separable from other layers above
and below by a discrete change in the character of the material deposited
or by a sharp physical break, deposition or both.
A stratum or body of strata recognized as a unit in the classification
of the rocks of the earth's crust with respect to any specific

A low-lying vegetated stretch of land or wide shallow ditch,
usually grassed or paved, which gathers or carries surface water runoff.

of water, whether natural or artificial, a drainage basin or subbasin.
