This Part 1 shall be known and may be cited as the "Schwenksville Borough Stormwater Management Ordinance."
The Borough Council of Schwenksville Borough finds that:
A. 
Inadequate management of accelerated runoff of stormwater resulting from development throughout a watershed increases runoff volumes, flows and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of streams and storm sewers, greatly increases the cost of public facilities to carry and control stormwater, undermines floodplain management and flood control efforts in 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 (SWM), including reasonable regulation of development and activities causing accelerated runoff, is fundamental to the public health, safety, and welfare and the protection of people of the commonwealth, their resources, and the environment.
C. 
Stormwater is an important water resource that provides groundwater recharge for water supplies and supports the base flow of streams.
D. 
The use of green infrastructure and low-impact development (LID) is intended to address the root cause of water quality impairment by using systems and practices which use or mimic natural processes to i) infiltrate and recharge, ii) evapotranspire, and/or iii) harvest and use precipitation near where it falls to earth. Green infrastructure practices and LID contribute to the restoration or maintenance of predevelopment hydrology.
E. 
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) program.
The purpose of this Part 1 is to promote health, safety, and welfare within the Borough and its watershed by minimizing the harms and maximizing the benefits described in § 140-2 of this Part 1, through provisions designed 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 this commonwealth.
B. 
Preserve natural drainage systems.
C. 
Manage stormwater runoff close to the source, reduce runoff volumes and mimic predevelopment hydrology.
D. 
Provide procedures and performance standards for stormwater planning and management.
E. 
Maintain groundwater recharge to prevent degradation of surface water and groundwater quality and to otherwise protect water resources.
F. 
Prevent scour and erosion of stream banks and streambeds.
G. 
Provide proper operation and maintenance of all stormwater best management practices (BMPs) that are implemented within the Borough.
H. 
Provide standards to meet NPDES permit requirements.
The Borough 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,[1] and/or the Act of October 4, 1978, P.L. 864 (Act 167), 32 P.S. § 680.1 et seq., as amended, the Stormwater Management Act.
[1]
Editor's Note: See 53 P.S. § 10101 et seq.
All regulated activities and all activities that may affect stormwater runoff, including land development and earth disturbance activity, are subject to regulation by this Part 1.
Any other ordinance provision(s) or regulation of the Borough inconsistent with any of the provisions of this Part 1 is hereby repealed to the extent of the inconsistency only.
In the event that a court of competent jurisdiction declares any section or provision of this Part 1 invalid, such decision shall not affect the validity of any of the remaining provisions of this Part 1.
Approvals issued and actions taken under this Part 1 do not relieve the applicant of the responsibility to secure required permits or approvals for activities regulated by any other code, law, regulation or ordinance.
Any permit or authorization issued or approved based on false, misleading or erroneous information provided by an applicant is void without the necessity of any proceedings for revocation. Any work undertaken or use established pursuant to such permit or other authorization is unlawful. No action may be taken by a board, agency or employee of the Borough purporting to validate such a violation.
A. 
If the Borough determines that any requirement under this Part 1 cannot be achieved for a particular regulated activity, the Borough may, after an evaluation of alternatives, approve measures other than those in this Part 1, subject to § 140-10B and C.
B. 
Waivers or modifications of the requirements of this Part 1 may be approved by the Borough if enforcement will exact undue hardship because of peculiar conditions pertaining to the land in question, provided that the modifications will not be contrary to the public interest and that the purpose of this Part 1 is preserved. Cost or financial burden shall not be considered a hardship. Modification may be considered if an alternative standard or approach will provide equal or better achievement of the purpose of this Part 1. A request for modifications shall be in writing and accompany the stormwater management site plan submission. The request shall provide the facts on which the request is based, the provision(s) of this Part 1 involved and the proposed modification.
C. 
No waiver or modification of any regulated stormwater activity involving earth disturbance greater than or equal to one acre may be granted by the Borough unless that action is approved in advance by the Department of Environmental Protection (DEP) or the delegated County Conservation District.
