[Ord. 524, 12/15/2010, § 101]
This Part shall be known and may be cited as the "Lower Swatara
Township Stormwater Management Ordinance."
[Ord. 524, 12/15/2010, § 102]
The governing body of Lower Swatara Township finds that:
A. Inadequate management of accelerated stormwater runoff resulting
from development throughout a watershed increases flood flows and
velocities, contributes to erosion and sedimentation, overtaxes the
carrying capacity of existing streams and storm sewers, greatly increases
the cost of public facilities to convey and manage stormwater, undermines
floodplain management and flood reduction efforts in upstream and
downstream communities, reduces groundwater recharge, threatens public
health and safety, and increases nonpoint source pollution of water
resources.
B. A comprehensive program of stormwater management, including reasonable
regulation of development and activities causing accelerated runoff,
is fundamental to the public health, safety, welfare, and the protection
of the people of Lower Swatara Township and all the people of the
commonwealth, their resources, and the environment.
C. Inadequate planning and management of stormwater runoff resulting
from land development and redevelopment throughout a watershed can
also harm surface water resources by changing the natural hydrologic
patterns; accelerating stream flows (which increase scour and erosion
of streambeds and stream banks thereby elevating sedimentation); destroying
aquatic habitat; and elevating aquatic pollutant concentrations and
loadings such as sediments, nutrients, heavy metals, and pathogens.
Groundwater resources are also impacted through loss of recharge.
D. Stormwater is an important water resource which provides groundwater
recharge for water supplies and base flow of streams, which also protects
and maintains surface water quality.
E. Public education on the control of pollution from stormwater is an
essential component in successfully addressing stormwater issues.
F. Federal and state regulations require certain municipalities to implement
a program of stormwater controls. These municipalities are required
to obtain a permit for stormwater discharges from their separate storm
sewer systems under the National Pollutant Discharge Elimination System
(NPDES).
G. Nonstormwater discharges to municipal separate storm sewer systems
can contribute to pollution of waters of the commonwealth.
[Ord. 524, 12/15/2010, § 103]
The purpose of this Part is to promote health, safety, and welfare within Lower Swatara Township, Dauphin County, by minimizing the harms and maximizing the benefits described in §
26-102 of this Part through provisions intended to:
A. Meet legal water quality requirements under state law, including
regulations at 25 Pa. Code, Chapter 93, to protect, maintain, reclaim,
and restore the existing and designated uses of the waters of the
commonwealth.
B. Manage accelerated runoff and erosion and sedimentation problems
close to their source by regulating activities that cause these problems.
C. Preserve the natural drainage systems to the maximum extent practicable.
D. Maintain groundwater recharge, to prevent degradation of surface
and groundwater quality, and to otherwise protect water resources.
E. Maintain existing flows and quality of streams and watercourses.
F. Preserve and restore the flood-carrying capacity of streams and prevent
scour and erosion of stream banks and streambeds.
G. Manage stormwater impacts close to the runoff source, with a minimum
of structures and a maximum use of natural processes.
H. Provide procedures, performance standards, and design criteria for
stormwater planning and management.
I. Provide proper operations and maintenance of all temporary and permanent
stormwater management facilities and best management practices (BMPs)
that are constructed and implemented.
J. Provide standards to meet the NPDES permit requirements.
K. Implement an "illegal discharge detection and elimination program"
within MS4 permitted urbanized areas to address nonstormwater discharges
into Lower Swatara Township's separate storm sewer system.
[Ord. 524, 12/15/2010, § 104]
1. Primary Authority. Lower Swatara Township is empowered to regulate
these activities by the authority of the Act of October 4, 1978, 32
P.S., P.L. 864 (Act 167), 32 P.S. § 680.1 et seq., as amended,
the "Storm Water Management Act."
2. Secondary Authority. Lower Swatara Township also is empowered to
regulate land use activities that affect runoff by the authority of
the Act of July 31, 1968, P.L. 805, No. 247, the Pennsylvania Municipalities
Planning Code, as amended.
[Ord. 524, 12/15/2010, § 105]
1. This Part shall apply to all areas of Lower Swatara Township, any
regulated activity within Lower Swatara Township, and all stormwater
runoff entering into Lower Swatara Township's separate storm sewer
system from lands within the boundaries of Lower Swatara Township.
2. Earth disturbance activities and associated stormwater management
controls are also regulated under existing state law and implementing
regulations. This Part shall operate in coordination with those parallel
requirements; the requirements of this Part shall be no less restrictive
in meeting the purposes of this Part than state law.
3. "Regulated activities" are any earth disturbance activities or any
activities that involve the alteration or development of land in a
manner that may affect stormwater runoff. "Regulated activities" include,
but are not limited to, the following listed items:
A. Earth disturbance activities.
D. Construction of new or additional impervious or semipervious surfaces.
E. Construction of new buildings or additions to existing buildings.
F. Diversion or piping of any natural or man-made stream channel.
G. Installation of stormwater management facilities or appurtenances
thereto.
H. Installation of stormwater BMPs.
4. See §
26-117 of this Part for exemption/modification criteria.
[Ord. 524, 12/15/2010, § 108]
Approvals issued and actions taken pursuant to this Part do
not relieve the applicant of the responsibility to comply with or
to secure required permits or approvals for activities regulated by
any other applicable codes, laws, rules, statutes, or ordinances.
To the extent that this Part imposes more rigorous or stringent requirements
for stormwater management, the specific requirements contained in
this Part shall be followed.
[Ord. 524, 12/15/2010, § 109]
Notwithstanding any provision(s) of this Part, including exemptions,
any landowner or any person engaged in the alteration or development
of land which may affect stormwater runoff characteristics shall implement
such measures as are reasonably necessary to prevent injury to health,
safety, or other property. Such measures also shall include actions
as are required to manage the rate, volume, direction, and quality
of resulting stormwater runoff in a manner which otherwise adequately
protects health, property, and water quality.
[Ord. 524, 12/15/2010, § 110]
The degree of stormwater management sought by the provisions
of this Part is considered reasonable for regulatory purposes. This
Part shall not create liability on the part of the Township, any appointed
or elected official of the Township, the Dauphin County Conservation
District or any officer, engineer or employee thereof for any erosion,
sedimentation or flood damages that result from reliance on this Part
or any administrative decision lawfully made thereunder.
