The purpose of this chapter is to promote public health, safety and welfare within the Township and its watersheds by minimizing the harms and maximizing the benefits described in § 206-2 of this chapter, through provisions designed to:
A. Manage stormwater runoff impacts at their source by regulating activities that cause the problems.
B. Provide review procedures and performance standards for stormwater planning and management.
C. Properly use and preserve existing drainage systems and watercourses.
D. Manage stormwater impacts close to the runoff source through reliance on natural processes and a minimum of structures.
E. Maximize infiltration of stormwater to maintain groundwater recharge, to prevent degradation of surface and groundwater quality, to otherwise protect water resources, and to promote the natural hydrologic regime.
F. Maintain and improve existing flows and quality of streams and watercourses.
G. Meet legal water quality requirements under Pennsylvania law, to protect and maintain existing uses and maintain the level of water quality to support those uses in all streams, and to protect and maintain water quality in special protection streams.
H. Prevent scour and erosion of streambanks and streambeds.
I. Provide for proper operations and maintenance of all stormwater management facilities within the Township.
J. Provide a mechanism to identify controls necessary to meet NPDBS requirements.
K Implement an illicit discharge detection and elimination program to address nonstormwater discharges into the Township's MS4 and watercourses within the Township.
