The purposes of this chapter shall be:
A.Â
To protect public health, safety and welfare by requiring stormwater
management whenever new, expanded or modified developments are proposed.
B.Â
To promote for the most efficient and beneficial uses of land and
water resources.
C.Â
To ensure that stormwater runoff from development is controlled so
that lake and stream water quality is protected, siltation minimized,
and flooding problems avoided.
D.Â
To provide for cost-effective and functionally effective stormwater
management, and to reduce the need for future remedial projects.
E.Â
To prevent soil erosion and sedimentation by requiring temporary
and permanent erosion control measures.
F.Â
To use the natural drainage system for conveying and receiving stormwater
runoff, and to minimize the need to construct storm drain pipes.
G.Â
To encourage multiple-purpose stormwater management which enhances
the environmental character of the Township.
H.Â
To allow wetlands to be used for stormwater detention in selected
locations, while ensuring that the natural functions and quality of
wetlands throughout the Township are protected to the maximum feasible
extent.
I.Â
To recognize private responsibility to incorporate stormwater management
systems into the early stages of site planning and design.
J.Â
To allow for off-site stormwater management under specified conditions.
K.Â
To ensure that all stormwater conveyance and detention facilities
will be properly maintained.
L.Â
To provide penalties for violation of the provisions of this chapter.
The following rules of construction apply to the text of this
chapter:

of the ordinance that is most restrictive shall apply.
The following words, terms and phrases, when used in this chapter,
shall have the meanings ascribed to them in this section, except where
the context clearly indicates a different meaning:
The increased movement of soils that occurs as a result of
man's activities.
A storm drain, as defined in this chapter.
A structure or facility, natural or artificial, which stores
stormwater on a temporary basis and releases it at a controlled rate.

in cubic feet per second.
An area of land subjected to the removal of vegetative cover
and/or earth-moving activities.
All facilities, measures, areas, and structures which serve
to convey, catch, filter, store, and/or receive stormwater, either
on a temporary or permanent basis (also see definitions for primary
drainage system and secondary drainage system).
A human-made change in the natural cover or topography of
land, including cut and fill activities, which may result in or contribute
to soil erosion or sedimentation of watercourses or wetlands. Earth
change does not include the practice of plowing and tilling soil for
the purpose of crop production.
A map which shows alterations of topography, alterations
of watercourses, flow directions of stormwater runoff, and proposed
stormwater management and erosion control measures.
A temporary rise in the level of any water body, watercourse
or wetland which inundates areas not ordinarily covered by water.
The relatively flat areas or lowlands adjoining a watercourse
or a body of water which has been or may be covered by floodwater.
A structure or designated area which allows runoff to gradually
seep into the ground, e.g., french drains, seepage pits, infiltration
basin, dry well, or perforated pipe.
A binding agreement which sets forth the terms and conditions
for the maintenance of erosion control measures and stormwater facilities.
A rate of flow of stormwater which does not cause erosion.
All or part of a drainage system which is located partially
or completely off of the development site which it serves.
The maximum allowable rate of stormwater flow from a storm
event, as measured at a given point and time in cubic feet per second.
Any individual, firm, partnership, association, corporation,
company, or organization of any kind, including government agencies,
conducting operations within the Township.
Facilities, structures, and areas which convey, store, or
