[Adopted 8-14-1995 by Ord. No. 95-7; amended 9-15-2014 by Ord. No. 14-03]
The Legislature of the Commonwealth of Pennsylvania has, by
the passage of the Pennsylvania Flood Plain Management Act of 1978,[1] delegated the responsibility to local governmental units
to adopt floodplain management regulations to promote public health,
safety, and the general welfare of its citizenry. Therefore, the Council
of the Borough of Tarentum does hereby order as follows.
[1]
Editor's Note: See 32 P.S. § 679.101 et seq.
The intent of this chapter is to:
A.
Promote the general health, welfare, and safety of the community.
B.
Encourage the utilization of appropriate construction practices in
order to prevent or minimize flood damage in the future.
C.
Minimize danger to public health by protecting water supply and natural
drainage.
D.
Reduce financial burdens imposed on the community, its governmental
units, and its residents, by preventing excessive development in areas
subject to flooding.
E.
Comply with federal and state floodplain management requirements.
A.
It shall be unlawful for any person, partnership, business or corporation
to undertake, or cause to be undertaken, any construction or development
anywhere within the Borough of Tarentum unless a permit has been obtained
from the Floodplain Administrator.
B.
A permit shall not be required for minor repairs to existing buildings
or structures.
This chapter supersedes any other conflicting provisions which
may be in effect in identified floodplain areas. However, any other
ordinance provisions shall remain in full force and effect to the
extent that those provisions are more restrictive. If there is any
conflict between any of the provisions of this chapter, the more restrictive
shall apply.
If any section, subsection, paragraph, sentence, clause, or
phrase of this chapter shall be declared invalid for any reason whatsoever,
such a decision shall not affect the remaining portions of the chapter,
which shall remain in full force and effect, and for this purpose
the provisions of this chapter are hereby declared to be severable.
A.
The degree of flood protection sought by the provisions of this chapter
is considered reasonable for regulatory purposes and is based on accepted
engineering methods of study. Larger floods may occur or flood heights
may be increased by man-made or natural causes, such as ice jams and
bridge openings restricted by debris. This chapter does not imply
that areas outside any identified floodplain areas or that land uses
permitted within such areas will be free from flooding or flood damages.
B.
This chapter shall not create liability on the part of the Borough
of Tarentum or any officer or employee thereof for any flood damages
that result from reliance on this chapter or any administrative decision
lawfully made thereunder.
A.
The Zoning Officer is hereby appointed to administer and enforce
this chapter and is referred to herein as the Floodplain Administrator.
The Floodplain Administrator may: (A) fulfill the duties and responsibilities
set forth in these regulations, (B) delegate duties and responsibilities
set forth in these regulations to qualified technical personnel, plan
examiners, inspectors, and other employees, or (C) enter into a written
agreement or written contract with another agency or private sector
entity to administer specific provisions of these regulations. Administration
of any part of these regulations by another entity shall not relieve
the community of its responsibilities pursuant to the participation
requirements of the National Flood Insurance Program as set forth
in the Code of Federal Regulations at 44 C.F.R. Section 59.22.
B.
In the absence of a designated Floodplain Administrator, the Floodplain
Administrator duties are to be fulfilled by the President of Council.
A permit shall be required before any construction or development
is undertaken within any area of the Borough of Tarentum.
A.
The Floodplain Administrator shall issue a permit only after it has
been determined that the proposed work to be undertaken will be in
conformance with the requirements of this and all other applicable
codes and ordinances.
B.
Prior to the issuance of any permit, the Floodplain Administrator
shall review the application for the permit to determine if all other
necessary government permits required by state and federal laws have
been obtained, such as those required by the Pennsylvania Sewage Facilities
Act[1] (Act 1966-537, as amended); the Pennsylvania Dam Safety
and Encroachments Act[2] (Act 1978-325, as amended); the Pennsylvania Clean Streams
Act[3] (Act 1937-394, as amended); and the U.S. Clean Water Act,
Section 404, 33, U.S.C. 1344. No permit shall be issued until this
determination has been made.
C.
During the construction period, the Floodplain Administrator or other
authorized official shall inspect the premises to determine that the
work is progressing in compliance with the information provided on
the permit application and with all applicable municipal laws and
ordinances. He/she shall make as many inspections during and upon
completion of the work as are necessary.
D.
In the discharge of his/her duties, the Floodplain Administrator
shall have the authority to enter any building, structure, premises
or development in the identified floodplain area, upon presentation
of proper credentials, at any reasonable hour to enforce the provisions
of this chapter.
E.
In the event the Floodplain Administrator discovers that the work
does not comply with the permit application or any applicable laws
and ordinances, or that there has been a false statement or misrepresentation
by any applicant, the Floodplain Administrator shall revoke the permit
and report such fact to the Council for whatever action it considers
necessary.
F.
The Floodplain Administrator shall maintain in perpetuity all records
associated with the requirements of this chapter including, but not
limited to, finished construction elevation data, permitting, inspection
and enforcement.
G.
The Floodplain Administrator is the official responsible for submitting
a biennial report to FEMA concerning community participation in the
National Flood Insurance Program.
H.
The responsibility, authority and means to implement the commitments
of the Floodplain Administrator can be delegated from the person identified.
However, the ultimate responsibility lies with the person identified
in the floodplain ordinance as the floodplain administrator/manager.
I.
The Floodplain Administrator shall consider the requirements of the
34 PA Code and the 2009 IBC and the 2009 IRC or latest revisions thereof.

any notice, order of direction of the Floodplain Administrator or
any other authorized employee of the municipality shall be guilty
of a summary offense and upon conviction shall pay a fine to Borough
of Tarentum, of not less than $25 nor more than $600 plus costs of
prosecution. In addition to the above penalties all other actions
are hereby reserved including an action in equity for the proper enforcement
of this chapter. The imposition of a fine or penalty for any violation
of, or noncompliance with this chapter shall not excuse the violation
or noncompliance or permit it to continue. All such persons shall
be required to correct or remedy such violations and noncompliance
within a reasonable time. Any development initiated or any structure
or building constructed, reconstructed, enlarged, altered, or relocated,
in noncompliance with this chapter may be declared by the Council
to be a public nuisance and abatable as such.
A.
Any person aggrieved by any action or decision of the Floodplain
Administrator concerning the administration of the provisions of this
chapter, may appeal to the Zoning Hearing Board. Such appeal must
be filed, in writing, within 30 days after the decision, determination
or action of the Floodplain Administrator.
B.
Upon receipt of such appeal the Zoning Hearing Board shall consider
the appeal in accordance with the Municipal Planning Code and any
other local ordinance.
A.
The identified floodplain area shall be:
(1)
Any areas of Borough of Tarentum, classified as Special Flood Hazard
Areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying
Flood Insurance Rate Maps (FIRMs) dated September 26, 2014 and issued
by the Federal Emergency Management Agency (FEMA) or the most recent
revision thereof, including all digital data developed as part of
the Flood Insurance Study, and
(2)
Any community identified flood hazard areas.
B.
The above referenced FIS and FIRMs, and any subsequent revisions
and amendments are hereby adopted by Borough of Tarentum and declared
to be a part of this chapter.
A.
The identified floodplain area shall consist of the following specific
areas:
(1)
The floodway area shall be those areas identified in the FIS and
the FIRM as floodway and which represent the channel of a watercourse
and the adjacent land areas that must be reserved in order to discharge
the base flood without increasing the water surface elevation by more
than one foot at any point. This term shall also include floodway
areas which have been identified in other available studies or sources
of information for those special flood hazard areas where no floodway
has been identified in the FIS and FIRM.
(a)
Within any floodway area, no encroachments, including fill,
new construction, substantial improvements, or other development shall
be permitted unless it has been demonstrated through hydrologic and
hydraulic analysis performed in accordance with standard engineering
practice that the proposed encroachment would not result in any increase
in flood levels within the community during the occurrence of the
base flood discharge.
(b)
Within any floodway area, no new construction or development
shall be allowed, unless the appropriate permit is obtained from the
Department of Environmental Protection Regional Office.
(2)
The AE Area/District shall be those areas identified as an AE Zone
on the FIRM included in the FIS prepared by FEMA for which base flood
elevations have been provided.
(a)
The AE Area adjacent to the floodway shall be those areas identified
as an AE Zone on the FIRM included in the FIS prepared by FEMA for
which base flood elevations have been provided and a floodway has
been delineated.
(3)
The A Area/District shall be those areas identified as an A Zone
on the FIRM included in the FIS prepared by FEMA and for which no
base flood elevations have been provided. For these areas, elevation
and floodway information from other federal, state, or other acceptable
sources shall be used when available. Where other acceptable information
is not available, the base flood elevation shall be determined by
using the elevation of a point on the boundary of the identified floodplain
area which is nearest the construction site.
B.
In lieu of the above, the municipality may require the applicant
to determine the elevation with hydrologic and hydraulic engineering
techniques. Hydrologic and hydraulic analyses shall be undertaken
only by professional engineers or others of demonstrated qualifications,
who shall certify that the technical methods used correctly reflect
currently accepted technical concepts. Studies, analyses, computations,
etc., shall be submitted in sufficient detail to allow a thorough
technical review by the municipality.
C.
Community identified flood hazard areas shall be those areas where
Borough of Tarentum has identified local flood hazard or ponding areas,
as delineated and adopted on a "local flood hazard map" using best
available topographic data and locally derived information such as
flood of record, historic high water marks, soils or approximate study
methodologies.
The identified floodplain area may be revised or modified by the Council where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change to the special flood hazard area, approval must be obtained from FEMA. Additionally, as soon as practicable, but not later than six months after the date such information becomes available, a community shall notify FEMA of the changes to the special flood hazard area by submitting technical or scientific data. See § 95-28B for situations where FEMA notification is required.
Should a dispute concerning any identified floodplain boundary
arise, an initial determination shall be made by the Borough of Tarentum
and any party aggrieved by this decision or determination may appeal
to the Council. The burden of proof shall be on the appellant.
Prior to development occurring in areas where annexation or
other corporate boundary changes are proposed or have occurred, the
community shall review flood hazard data affecting the lands subject
to boundary changes. The community shall adopt and enforce floodplain
regulations in areas subject to annexation or corporate boundary changes
which meet or exceed those in 44 CFR 60.3.
A.
Alteration or relocation of watercourse.
(1)
No encroachment, alteration, or improvement of any kind shall be
made to any watercourse until all adjacent municipalities which may
be affected by such action have been notified by the municipality,
and until all required permits or approvals have first been obtained
from the Department of Environmental Protection Regional Office.
(2)
No encroachment, alteration, or improvement of any kind shall be
made to any watercourse unless it can be shown that the activity will
not reduce or impede the flood carrying capacity of the watercourse
in any way.
(3)
In addition, FEMA and the Pennsylvania Department of Community and
Economic Development, shall be notified prior to any alteration or
relocation of any watercourse.
B.
When a community proposes to permit the following encroachments:
(1) any development that causes a rise in the base flood elevations
within the floodway; or (2) any development occurring in Zones A1-30
and Zone AE without a designated floodway, which will cause a rise
of more than one foot in the base flood elevation; or (3) alteration
or relocation of a stream (including but not limited to installing
culverts and bridges), the applicant shall (as per 44 CFR Part 65.12):
(1)
Apply to FEMA for conditional approval of such action prior to permitting
the encroachments to occur.
(2)
Upon receipt of the Administrator's conditional approval of
map change and prior to approving the proposed encroachments, a community
shall provide evidence to FEMA of the adoption of floodplain management
ordinances incorporating the increased base flood elevations and/or
revised floodway reflecting the post-project condition.
(3)
Upon completion of the proposed encroachments, a community shall
provide as-built certifications. FEMA will initiate a final map revision
upon receipt of such certifications in accordance with 44 CFR Part
67.
