ARTICLE I- GENERAL PROVISIONS
Section 101. Statement of Findings
The governing body of the Municipality 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 reduction efforts in upstream and 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 erosion, is fundamental to the public
health, safety, welfare, and the protection of the people of the Municipality and all the
people of the Commonwealth, their resources, and the environment.
C.
Inadequate management of accelerated stormwater runoff resulting from development
throughout a watershed poses a threat to surface and groundwater quality.
D.
Through project design, impacts from stormwater runoff can be minimized to maintain the
natural hydrologic regime, and sustain high water quality, groundwater recharge, stream
baseflow and aquatic ecosystems. The most cost effective and environmentally
advantageous way to manage storm water runoff is through nonstructural project design,
minimizing impervious surfaces and sprawl, avoiding sensitive areas (i.e. buffers,
floodplains, steep slopes), and designing to topography and soils to maintain the natural
hydrologic regime.
E.
To effectively monitor the maintenance of base flow within the watershed, a tracking of
consumptive use including storm water discharges and groundwater withdrawals is critical
to complying with anti-degradation, the Acts goals and policy, and the regulatory
requirement to maintain base flow and stream health.
Section 102. Purpose
The purpose of this Ordinance is to promote the public health, safety, and welfare within the
Brodhead/McMichaels Creek Watersheds by maintaining the natural hydrologic regime by
minimizing the impacts described in Section 101 of this Ordinance through provisions designed
to:
A.
Promote alternative project designs and layout that minimizes impacts to surface and
ground water.
B.
Promote nonstructural BMPs.
C.
Minimize increases in stormwater volume.
D.
Minimize impervious surfaces. 7
E.
Manage accelerated runoff and erosion and sedimentation problems at their source by
regulating activities that cause these problems during construction.
F.
Utilize and pre
