This chapter shall be known and may be cited as the "Municipality
of Monroeville) Stormwater Management Ordinance."
The governing body of the Municipality finds that:
A. Inadequate management of accelerated runoff of stormwater resulting
from development throughout a watershed increases runoff volumes,
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 (SWM), including
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 that provides groundwater
recharge for water supplies and supports the base flows of streams.
D. The use of green infrastructure (GI) and low-impact development (LID)
are intended to address the root cause of water quality impairment
by using systems and practices which use or mimic natural processes
to infiltrate and recharge, evapotranspire, and/or harvest and use
precipitation near where it falls to earth. Green infrastructure practices
and LID contribute to the restoration or maintenance of predevelopment
hydrology.
E. 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) program.
The standards contained herein shall apply to all regulated
activities within the Municipality and all stormwater runoff entering
the Municipality's separate storm sewer system from lands within and
tributary to the Municipal boundary, including the sources of such
runoff.
A. Activities regulated by this chapter include, but are not limited
to, the following:
(3) Construction of new or additional impervious or semipervious surfaces
(driveways, parking lots, etc.).
(4) Construction of new buildings or additions to existing buildings.
(5) Installation, maintenance, and alterations to stormwater management
facilities or appurtenances thereto.
(6) Any earth disturbances or any activities that involve the alteration
or development of land or removal of trees and vegetation in a manner
that may affect post-construction stormwater runoff.
(7) New earth-disturbance activities on a previously developed property,
which includes properties that have been graded, altered, and/or compacted,
whether or not any structures have been built.
(8) The demolition or partial demolition of an existing facility, however
such work required for building or site maintenance, parking lot resurfacing,
roof replacement, building exterior repairs, etc., shall not constitute
a regulated activity unless deemed so by the Municipality.
(9) Construction of new buildings or facilities in existing impervious
or semipervious areas.
Any ordinance or ordinance provision of the Municipality inconsistent
with any of the provisions of this chapter is hereby repealed to the
extent of the inconsistency only; provided, however, that this repeal
shall in no manner be construed as a waiver, release or relinquishment
of the right to initiate, pursue or prosecute, as the case may be,
any proceeding at law or in equity pertaining to any act done which
would have constituted a violation of such prior ordinance or ordinance
provision. All of said ordinance or ordinance provisions shall remain
in full force and effect and are not repealed hereby as they pertain
to such acts and to the processing of such plans filed prior to the
effective date of this chapter, which are protected from the effect
of intervening ordinances by Section 508(4) of the Pennsylvania Municipalities
Planning Code.
Should any section or provision of this chapter be declared
invalid by a court of competent jurisdiction, such determination of
invalidity shall not affect the validity of the remaining provisions
of this chapter.
Permits and approvals issued pursuant to this chapter shall
not relieve the applicant of the responsibility to comply with or
to secure other required permits or approvals for activities regulated
by any other applicable code, rule, act, statute or ordinance. This
chapter shall not preclude the inclusion in such other permit of more
stringent requirements concerning regulation of stormwater and erosion.
Where a conflict exists between a provision within this chapter and
that of the PADEP Phase II NPDES regulations, as amended, or any other
ordinance of the Municipality, the more stringent requirements shall
govern.
Any permit or authorization issued or approved based on false,
misleading or erroneous information provided by an applicant is void
without the necessity of any proceedings for revocation. Any work
undertaken or use established pursuant to such permit or other authorization
is unlawful. No action may be taken by a board, agency or employee
of the Municipality purporting to validate such a violation.
Any reference to a statute, regulation or standard, shall be
interpreted to refer to the latest or most current version of that
document.
