The Board of Supervisors of Salem Township finds that:
A.
Inadequate management of accelerated runoff of stormwater resulting from development throughout a watershed increases flood flow volumes and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of streams and storm sewers, greatly increases the costs of public facilities to carry and control stormwater, undermines floodplain management and flood control efforts in downstream communities, reduces groundwater recharge, deteriorates the water quality of receiving waters 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 and welfare and the protection of the people of Salem Township and all the people of the commonwealth, their resources and the environment.
