[Added by Ord. 2017-05, 9/20/2017[1]]
The Legislature of the Commonwealth of Pennsylvania has, by
the passage of the Pennsylvania Flood Plain Management Act of 1978,[2] 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 Board
of Supervisors of the Township of Franklin does hereby order as follows.
[Added by Ord. 2017-05, 9/20/2017]
1.
Intent. The intent of this Part 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.
2.
Applicability. 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 Flood Hazard District
as defined by the Township of Franklin unless a permit has been obtained
from the Floodplain Administrator.
3.
Abrogation and Greater Restrictions. This Part 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 Part,
the more restrictive shall apply.
4.
Severability. If any section, subsection, paragraph, sentence, clause,
or phrase of this Part shall be declared invalid for any reason whatsoever,
such a decision shall not affect the remaining portions of the Part,
which shall remain in full force and effect, and for this purpose
the provisions of this Part are hereby declared to be severable.
5.
Warning and Disclaimer of Liability.
A.
The degree of flood protection sought by the provisions of this Part
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 Part 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 Part shall not create liability on the part of the Township
of Franklin or any officer or employee thereof for any flood damages
that result from reliance on this Part or any administrative decision
lawfully made thereunder.
[Added by Ord. 2017-05, 9/20/2017]

or development is undertaken within any area of the Flood Hazard District
as defined by the FIRM, FIS, and the Township of Franklin.
3.
Duties and Responsibilities of the Floodplain Administrator.
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 (Act 1966-537, as amended);[1] the Pennsylvania Dam Safety and Encroachments Act (Act
1978-325, as amended);[2] the Pennsylvania Clean Streams Act (Act 1937-394, as amended);[3] and the United States Clean Water Act, Section 404, 33
U.S.C. § 1344. No permit shall be issued until this determination
has been made.
C.
In the case of existing structures, prior to the issuance of any
development/permit, the Floodplain Administrator shall review the
proposed cost of improvements or repairs and the pre-improvement market
value of the structure, so that a substantial improvement/substantial
damage determination can be made, in accordance with FEMA's Substantial
Improvement/Substantial Damage Desk Reference.
D.
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.
E.
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 Part.
F.
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 Board of Supervisors for whatever action
it considers necessary.
G.
The Floodplain Administrator shall maintain in perpetuity, or for
the lifetime of the structure, all records associated with the requirements
of this Part, including, but not limited to, finished construction
elevation data, permitting, inspection and enforcement.
H.
The Floodplain Administrator is the official responsible for submitting
a biennial report to FEMA concerning community participation in the
National Flood Insurance Program as requested.
I.
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.
J.
The Floodplain Administrator shall consider the requirements of the
34 Pa. Code and the 2009 IBC and the 2009 IRC, or the latest revision
thereof as adopted by the Commonwealth of Pennsylvania.

provided. Such notice shall:
(1)
Be in writing;
(2)
Include a statement of the reasons for its issuance;
(3)
Allow a reasonable time not to exceed a period of 30 days for
the performance of any act it requires;
(4)
Be served upon the property owner or his agent as the case may
require; provided, however, that such notice or order shall be deemed
to have been properly served upon such owner or agent when a copy
thereof has been served with such notice by any other method authorized
or required by the laws of this state;
(5)
Contain an outline of remedial actions which, if taken, will
effect compliance with the provisions of this Part.
10.
Appeals.
A.
Any person aggrieved by any action or decision of the Floodplain
Administrator concerning the administration of the provisions of this
Part, 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.
[Added by Ord. 2017-05, 9/20/2017]
1.
Identification.
A.
The Flood Hazard District, also known as the identified floodplain
area, shall be:
(1)
Any areas of the Township of Franklin, classified as special
flood hazard areas (SFHAs) in the Flood Insurance Study (FIS) and
the accompanying Flood Insurance Rate Maps (FIRMs) dated September
29, 2017, 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 Township of Franklin and declared
to be a part of this Part.
2.
Description and Special Requirements of Identified Floodplain Areas.
The identified floodplain area shall consist of the following specific
areas:
A.
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.
(1)
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.
(2)
Within any floodway area, no new construction or development
shall be allowed, unless the appropriate permit is obtained from the
Department of Environmental Protection's regional office.
B.
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.
(1)
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.
(2)
AE Area without 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 but no floodway has been
determined.
(a)
No encroachments, including fill, new construction, substantial
improvements, or other development shall be permitted in an AE Zone
without floodway, unless it has been demonstrated through hydrologic
and hydraulic analysis performed in accordance with standard engineering
practice that the proposed development, together with all other existing
and anticipated development, would not result in an increase in flood
levels of more than one foot within the entire community during the
occurrence of the base flood discharge.
(b)
No new construction or development shall be located within the
area measured 50 feet landward from the top-of-bank of any watercourse,
unless the appropriate permit is obtained from the Department of Environmental
Protection's regional office.
C.
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.
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. In the absence of any of the
above data or documentation, the community may require elevation of
the lowest floor to be at least three feet above the highest adjacent
grade.
D.
The AO and AH Area/District shall be those areas identified as Zones
AO and AH on the FIRM and in the FIS. These areas are subject to inundation
by 1% annual chance shallow flooding where average depths are between
one foot and three feet. In Zones AO and AH, drainage paths shall
be established to guide floodwaters around and away from structures
on slopes.
E.
Community-identified flood hazard areas shall be those areas where
the Township of Franklin has identified local flood hazard or ponding
areas, as delineated and adopted on a local flood hazard map using
the best available topographic data and locally derived information
such as flood of record, historic high-water marks, soils or approximate
study methodologies.
3.
Changes in Identification of Area. The Identified Floodplain Area may be revised or modified by the Board of Supervisors 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 § 27-1305, Subsection 1B, for situations where FEMA notification is required.
4.
Boundary Disputes. Should a dispute concerning any identified floodplain
boundary arise, an initial determination shall be made by the Floodplain
Administrator and any party aggrieved by this decision or determination
may appeal to the Zoning Hearing Board. The burden of proof shall
be on the appellant.
5.
Jurisdictional Boundary Changes. 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.
[Added by Ord. 2017-05, 9/20/2017]
1.
General.
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's 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 the Township of Franklin proposes to permit the following encroachments:
any development that causes a rise in the base flood elevations within
the floodway; or 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 alteration or relocation
of a stream (including, but not limited to, installing culverts and
bridges), the applicant shall (as per 44 CFR 65.12):
(1)
Apply to FEMA for conditional approval of such action prior
to permitting the encroachments to occur.
(2)
Upon receipt of the FEMA 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, the applicant
shall provide as-built certifications. FEMA will initiate a final
map revision upon receipt of such certifications in accordance with
44 CFR 67.
C.
Any new construction, development, uses or activities allowed within
any identified floodplain area shall be undertaken in strict compliance
with the provisions contained in this Part and any other applicable
codes, ordinances and regulations.
