[Ord. 334 (92-1), 2/5/1992, § 101]
1. 
The Borough Council of the Borough finds that:
A. 
Inadequate management of accelerated runoff of stormwater resulting from development throughout a watershed increases flood flow 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, and threatens public health and safety.
B. 
A comprehensive program of stormwater management, including reasonable regulation of development and activities causing accelerated runoff, is fundamental to the public health, safety and welfare and the protection of the people of the commonwealth, their resources and the environment.
[Ord. 334 (92-1), 2/5/1992, § 102]
1. 
The purpose of this Chapter is to promote the public health, safety and welfare within the South Branch Codorus Creek Watershed by minimizing the damages described in § 23-101, Subsection 1A of this Chapter by provisions designed to:
A. 
Control accelerated runoff and erosion and sedimentation problems at their source by regulating activities which cause such problems.
B. 
Utilize and preserve the desirable existing natural drainage systems.
C. 
Encourage recharge of groundwaters where appropriate.
D. 
Maintain the existing flow and quality of streams and watercourses in the Borough and the commonwealth.
E. 
Preserve and restore the flood carrying capacity of streams.
F. 
Provide for proper maintenance of all permanent stormwater management structures which are constructed in the Borough.
[Ord. 334 (92-1), 2/5/1992, § 103]
The Borough is empowered to regulate these activities by the authority of the Act of October 4, 1978, P.L. 864 (Act 167), the "Stormwater Management Act," 32 P.S. § 680.1 et seq., and the Borough Code, 53 P.S. § 45101 et seq.

1. 
This Chapter shall apply only to permanent stormwater management facilities constructed as part of any of the activities listed in this Section. Erosion and sedimentation control during construction involved with any of these activities are specifically not regulated by this Chapter, but shall continue to be regulated under existing laws and ordinances.
2. 
This Chapter contains only those stormwater runoff control criteria and standards which are necessary or desirable from a total watershed perspective.
3. 
Storm sewer inlet systems, stormwater swales and culverts shall be designed in accordance with the latest versions of Pennsylvania Department of Transportation Design Manual, Part 2, and the Pennsylvania Department of Environmental Protection regulations, 25 Pa. Code, Chapters 105 and 106.
4. 
The following activities are defined as regulated activities and shall be regulated by this Chapter, except those which meet the waiver specifications presented hereafter:
A. 
Land development.
B. 
Subdivisions involving new impervious surfaces.
C. 
Construction of new or additional impervious surfaces (driveways, parking lots, etc.)
D. 
Construction of new buildings or additions to existing buildings.
E. 
Diversion or piping of any natural or man-made stream channel.
F. 
Installation of stormwater systems or appurtenances thereto.
5. 
Should any stormwater management facility qualify as a dam under Pennsylvania Department of Environmental Protection regulations, 25 Pa. Code, Chapter 105, the facility shall be designed in accordance with Chapter 105 and meet the regulations of Chapter 105 concerning dam safety. Construction or modification of any culvert, bridge or any facilities that constitute stream enclosures, as described in PA DEP regulations, Chapter 25 Pa. Code, Chapter 105, (as amended or replaced from time to time by PA DEP), shall be designed in accordance with Chapter 105 and will require a permit from PA DEP. Any facility located within and/or discharging to a PennDOT right-of-way must meet PennDOT minimum design standards and permit submission requirements. Any earth disturbance activity must be conducted in accordance with PA DEP, 25 Pa. Code, Chapter 102, regulations.
