BE AND IT IS HEREBY ORDAINED AND ENACTED by the Board of Supervisors of the Township of West Earl, Lancaster County, Pennsylvania, as follows: Section 1.

9 The Code of Ordinances of the Township of West Earl, Chapter 149, Storm Water Management, shall be deleted in its entirety and a new Chapter 149, Storm Water Management, shall be inserted which shall provide as follows: ARTICLE I GENERAL PROVISIONS 149-1. Short Title This Chapter shall be known and may be cited as the West Earl Township Stormwater Management Ordinance. 149-2. Statement of Findings The Board of Supervisors finds that: A. Inadequate management of accelerated stormwater runoff resulting from development throughout a watershed increases flood flows and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of existing streams and storm sewers, greatly increases the cost of public facilities to convey and manage stormwater, undermines floodplain management and flood control efforts in downstream communities, reduces groundwater recharge.

10 Threatens public health and safety, and increases nonpoint source pollution of water resources. B. A comprehensive program of SWM, including reasonable regulation of development and 5 activities causing accelerated runoff, is fundamental to the public health, safety, welfare, and the protection of the people of the Township and all the 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.
