The Board of Supervisors of Concord 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, and threatens public health and safety.
B. 
A comprehensive program of stormwater management, including reasonable regulation of development and activities causing accelerated erosion, is fundamental to the public health, safety, welfare, and the protection of the people of the Township and all of the people of the commonwealth, their resources, and the environment.
The purpose of this part is to promote health, safety, and welfare within the Township, implement the requirements of the Chester Creek Stormwater Management Plan, and implement the requirements of the National Pollutant Discharge Elimination System Phase II (NPDES II) by minimizing the damages described in § 148-33A of this part through provisions designed to:
A. 
Manage accelerated runoff, erosion, and sedimentation problems at their source by regulating activities that cause these problems;
B. 
Utilize and preserve the existing natural drainage systems;
C. 
Encourage recharge of groundwater where appropriate and prevent degradation of groundwater quality;
D. 
Maintain existing flows and quality of streams and watercourses in the Township and the commonwealth;
E. 
Preserve and restore the flood-carrying capacity of streams;
F. 
Provide proper maintenance of all permanent stormwater management facilities that are constructed in the Township; and
G. 
Provide performance standards and design criteria for watershed-wide stormwater management and planning.
The Township is empowered to regulate land use activities that affect runoffs by the authority of the Act of October 4, 1978, P.L. 864 (Act 167), 32 P.S., § 680.1 et seq., as amended, the Storm Water Management Act, the Pennsylvania Municipalities Planning Code,[1] Act 247, as amended, and the Code of the Township of Concord, Chapter 148 (SLDO), Part 1, and the regulations of the PA Department of Environmental Protection NPDES Phase II.

B. 
This part shall only apply to permanent stormwater management facilities constructed as part of any of the regulated activities listed in this section. Stormwater management and erosion and sedimentation control during construction activities are specifically not regulated by this part but shall continue to be regulated under existing laws and ordinances.
C. 
This part contains only the stormwater management performance standards and design criteria that are necessary or desirable from a watershed-wide perspective. Local stormwater management design criteria (e.g., inlet spacing, inlet type, collection system design and details, outlet structure design, etc.) shall continue to be regulated by the applicable Township ordinances or at the Township Engineer's discretion.
D. 
The following activities are defined as "regulated activities" and shall be regulated by this part:
(1) 
Land development and/or redevelopment.
(2) 
Subdivision.
(3) 
Construction of new or additional impervious or semipervious surfaces (driveways, parking lots, etc.).
(4) 
Construction of new buildings or additions to existing buildings.
(5) 
Diversion or piping of any natural or man-made stream channel.
(6) 
Installation of stormwater management facilities or appurtenances thereto.
(7) 
Placement of fill material.
Any ordinance or ordinance provision of the Township inconsistent with any of the provisions of this part is hereby repealed to the extent of the inconsistency only.
Should any section or provision of this part be declared invalid by a court of competent jurisdiction, such decision shall not affect the validity of any of the remaining provisions of this part.
Approvals issued 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, rules, statutes, or ordinances.
