[Ord. 447, 1/2/2007, § 101]
This chapter shall be known and may be cited as the "West Lebanon Township Stormwater Management Ordinance."
[Ord. 447, 1/2/2007, § 102]
1. 
The Board of Commissioners of the Township finds that:
A. 
Inadequate management of accelerated runoff of stormwater resulting from development throughout a watershed increases 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, 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, which provides groundwater recharge for water supplies and base flow of streams, which also protects and maintains surface water quality.
D. 
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).
[Ord. 447, 1/2/2007, § 103]
1. 
The purpose of this chapter is to promote health, safety, and welfare within the Township and its watershed by minimizing the harms and maximizing the benefits described in § 23-102 of this chapter, 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.
B. 
Preserve the natural drainage systems as much as possible.
C. 
Manage stormwater runoff close to the source.
D. 
Provide procedures and performance standards for stormwater planning and management.
E. 
Maintain groundwater recharge, to prevent degradation of surface and groundwater, quality and to otherwise protect water resources.
F. 
Prevent scour and erosion of stream banks and streambeds.
G. 
Provide proper operations and maintenance of all permanent SWM BMPs that are implemented within the Township.
H. 
Provide standards to meet NPDES permit requirements.
