A.
The provisions of Article XV (hereinafter "this article") supersede any other conflicting provisions of the Code, ordinances or resolutions of Lower Frederick Township which may apply to the Floodplain Conservation District.
B.
However, any other provisions of the Code, ordinances or resolutions
of Lower Frederick Township 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 article, the
more restrictive shall apply.
C.
If any section, subsection, paragraph, sentence, clause, or phrase
in this article shall be declared invalid for any reason whatsoever,
such a decision shall not affect the remaining portions of this article,
which shall remain in full force and effect, and for this purpose
the provisions of this article are hereby declared to be severable.
A.
The degree of flood protection sought by the provisions of this article
is considered reasonable for regulatory purposes and is based on acceptable
engineering methods of study. Larger floods may occur on rare occasions.
Flood heights may be increased by man-made or natural causes, such
as ice jams and bridge openings restricted by debris. This article
does not imply that areas outside the floodplain districts or that
land uses permitted within such districts will be free from flooding
or flood damage.
B.
This article shall not create liability on the part of the Township
or any officer or employee thereof for any flood damages that result
from reliance on this article or any administrative decision lawfully
made thereunder.
The FP Floodplain Conservation District is defined and established
as those areas of the Township subject to flooding as defined in Subsections
A and B. The use of the words "floodplain" or "flood plain" shall
encompass the definition of the Floodplain Conservation District of
this article.
A.
The identified floodplain area shall be those areas of Lower Frederick
Township which are subject to inundation by the waters of the one-percent
annual chance flood, as identified in the Flood Insurance Study (FIS)
dated March 2, 2016, or the most recent revision thereof, and the
accompanying Flood Insurance Rate Map (FIRM) for Montgomery County
dated March 2, 2016, prepared for the Township by the Federal Emergency
Management Agency (FEMA), or the most recent revision thereof. The
identified floodplain area shall consist of the following specific
areas:
(1)
FW (floodway area): the areas identified as floodway in the
AE Zone in the Flood Insurance Study prepared by the FEMA. The term
shall also include floodway areas which have been identified in other
available studies or sources of information for those floodplain areas
where no floodway has been identified in the Flood Insurance Study.
(2)
FF (flood-fringe area): the remaining portions of the one-hundred-year
floodplain in those areas identified as an AE Zone in the Flood Insurance
Study where a floodway has been delineated. The basis for the outermost
boundary of this area shall be the one-hundred-year-flood elevations
as shown in the flood profiles contained in the Flood Insurance Study.
(3)
FA (general floodplain area): the areas identified as Zone A
in the Flood Insurance Study for which no one-hundred-year-flood elevations
have been provided. When available, information from other federal,
state, and other acceptable sources shall be used to determine the
one-hundred-year elevation, as well as a floodway area, if possible.
When no other information is available, the one-hundred-year elevation
shall be determined by using a point on the boundary of the identified
floodplain area which is nearest the construction site in question.
(4)
The Township 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 Township.
B.
Additional areas.
(1)
The FP Floodplain Conservation District shall also include soils
with a frequency of flooding of 1% or greater per year, as delineated
by the Natural Resources Conservation Service, United States Department
of Agriculture Web-Based Soil Survey (available online at http://websoilsurvey.nrcs.usda.gov/),
including the following soils:
C.
The Floodplain District shall be delineated according to FEMA's Flood Insurance Rate Map (FIRM) for Lower Frederick Township which is hereby made a part of this article, and additional area based on soils as described in § 170-106B. The FIRM is available for inspection at the Township office. Further delineation shall be subject to the following criteria:
(1)
All changes to the Floodplain District are subject to review
and approval of FEMA. The Floodplain Conservation District 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, after submission of technical information or data to FEMA
and approval by FEMA of the proposed revision or modification.
(2)
Studies used to establish the floodplain boundaries shall be
available in the Township office for reference. Whenever there is
a difference between the map and the data contained in the studies,
the data contained in the studies shall determine the boundary of
the district.
(3)
Should a dispute concerning any identified floodplain boundary
arise, an initial determination shall be made by Lower Frederick Township.
Any changes in the boundaries of the Floodplain District shall be
subject to the review and approval of the Federal Insurance Administrator.
(4)
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.
The Floodplain District shall be an overlay on all zoning districts
and shall function in accordance with the following:
A.
For any lot or portion thereof lying within the floodplain, the regulations
of the Floodplain District shall take precedence over the regulations
of the underlying district.
B.
Should the underlying zoning of any lot or any part thereof which
is located in the Floodplain District be changed through any legislative
or judicial action, such change shall have no effect on the overlying
Floodplain District, unless such change was included as part of the
original application.
C.
Should the overlying Floodplain District be declared inappropriate
to any lot through any legislative or judicial actions, such change
shall have no effect on the underlying zoning district.
A.
The Floodplain Conservation District shall include the following
specific areas/districts:
(1)
The Floodway Area/District shall be those areas identified as
floodway on the FIRM as well as those floodway areas which have been

those special floodplain areas where no floodway has been identified
in the FIS. The floodway represents the channel of a watercourse and
the adjacent land areas that must be reserved in order to discharge
the base flood without cumulatively increasing the water surface elevation
by more than one foot at any point.
(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)
No new construction or development shall be allowed, unless
a permit is obtained from the Department of Environmental Protection
Regional Office.

Specific definitions. As used in this article, the following terms
shall have the meanings indicated:
A use or structure on the same lot with, and/or having a
nature customarily incidental and subordinate to, the principal use
or structure.
A flood which has a one-percent chance of being equaled or
exceeded in any given year (also called the "one-hundred-year flood").
The elevation shown on the Flood Insurance Rate Map (FIRM)
for Zones AE, AH and A1-30 that indicates the water surface elevation
resulting from a flood that has a one-percent or greater chance of
being equaled or exceeded in any given year. The BFE is also shown
on the FIS profile and can be determined for Zone A floodplains.
Any area of the building having its floor below ground level
on all sides.
A combination of materials to form a permanent structure
having walls and a roof. Included shall be all manufactured homes
and trailers to be used for human habitation.
A space which will remain totally dry during flooding; the
structure is designed and constructed to prevent the passage of water
and water vapor.
Any man-made change to improved or unimproved real estate,
including but not limited to the construction, reconstruction, renovation,
repair, expansion, or alteration of buildings, or other structures;
the placement of manufactured homes; streets, and other pavings; utilities;
filling, grading, and excavation; mining; dredging; drilling operations;
storage of equipment or materials; and the subdivision of land.
A space which will remain dry during flooding, except for
the passage of some water vapor or minor seepage; the structure is
substantially impermeable to the passage of water.
A manufactured home park or subdivision for which the construction
of facilities for servicing the lots on which the manufactured homes
are to be affixed (including, at a minimum, the installation of utilities,
the construction of streets, and either final site grading or the
pouring of concrete pads) is completed before the effective date of
the floodplain management regulations adopted by a community.
The preparation of additional sites by the construction of
facilities for servicing the lots on which the manufactured homes
are to be affixed (including the installation of utilities, the construction
of streets, and either final site grading or the pouring of concrete
pads).
A temporary inundation of normally dry land areas.
The official map on which the Federal Emergency Management
Agency has delineated both the areas of special flood hazard and the
risk premium zones applicable to the community.
The official report provided by the Federal Insurance Administration
that includes flood profiles, the Flood Insurance Rate Map, the Flood
Boundary and Floodway Map, and the water surface elevation of the
base flood.
A relatively flat or low land area which is subject to partial
or complete inundation from an adjoining or nearby stream, river,
or watercourse; and/or any area subject to the unusual and rapid accumulation
of surface waters from any source.
Any combination of structural and nonstructural additions,
changes, or adjustments to structures which reduce or eliminate flood
damage to real estate or improved real property, water, and sanitary
facilities, structures and their contents.
Flood-resistant material includes any building product capable
of withstanding direct and prolonged contact with floodwaters without
sustaining significant damage. Prolonged contact means at least 72
hours. Significant damage is any damage requiring more than low-cost
cosmetic repair (such as painting). All structural and nonstructural
building materials at or below the base flood elevation (BFE) must
be flood-resistant.
The designed area of a floodplain required to carry and discharge
floodwaters of a given magnitude. For the purposes of this article,
the floodway shall be capable of accommodating a flood of the one-hundred-year
magnitude.
That part of the floodplain adjacent to and extending from
the floodway and subject to inundation by the one-hundred-year flood.

The lowest floor of the lowest fully enclosed area (including
basement). An unfinished, flood-resistant partially enclosed area,
used solely for parking of vehicles, building access, and incidental
storage, in an area other than a basement area is not considered the
lowest floor of a building, provided that such space is not designed
and built so that the structure is in violation of the applicable
nonelevation design requirements of this article.
A transportable, single-family dwelling intended for permanent
occupancy, an office, or a place of assembly, contained in one or
more sections, built on a permanent chassis, which arrives at a site

oil, waste, vent, or similar piping, electric wiring or mechanical
or other work affecting public health or general safety.
Structures for which the start of construction commenced
on or after March 2, 2016, and includes any subsequent improvements
thereto. Any construction started after September 30, 1977, and before
March 2, 2016 (the effective start date of this floodplain management
article), is subject to the ordinance in effect at the time the permit
was issued, provided the start of construction was within 180 days
of permit issuance.
A manufactured home park or subdivision for which the construction
of facilities for servicing the lots on which the manufactured homes
are to be affixed (including, at a minimum, the installation of utilities,
the construction of streets, and either final site grading or the
pouring of concrete pads) is completed on or after the effective date
of floodplain management regulations adopted by a community.
A flood that, on the average, is likely to occur once every
100 years (i.e., that has a one-percent chance of occurring each year,
although the flood may occur in any year). Also referred to as the
"one-percent-frequency flood" or the "base flood," as defined by FEMA
in the Flood Insurance Study for Lower Frederick Township.

occurred after September 30, 1977, the date of the initial FEMA Flood
Insurance Rate Map, and, as such, would be required to be compliant
with the regulations of the NFIP.
A structure for which construction or substantial improvement
occurred on or before September 30, 1977, the date of the initial
FEMA Flood Insurance Rate Map, and, as such, would not be required
to be compliant with the regulations of the NFIP.
A vehicle which is: built on a single chassis; not more than
400 square feet, measured at the largest horizontal projections; designed
to be self-propelled or permanently towable by a light-duty truck;
and not designed for use as a permanent dwelling but as temporary
living quarters for recreational, camping, travel, or seasonal use.
The regulatory flood elevation is the elevation to which
development is regulated for purposes of elevation and/or dry floodproofing.
It is equal to the base flood elevation (BFE) plus a freeboard of
1 1/2 feet.
Flood-related damages sustained by a structure on two separate
occasions during a ten-year period for which the cost of repairs at
the time of each such flood event, on average, equals or exceeds 25%
of the market value of the structure before the damages occurred.
An area in the floodplain subject to a one-percent or greater
chance of flooding in any given year. It is shown on the FIRM as Zone
A, AO, A1-A30, AE, A99, or AH.
The areas identified as Zone AE in the Flood Insurance Study,
where one-hundred-year flood elevations have been provided, but no
floodway has been delineated.

homes, jails, and new manufactured home parks and subdivisions and
substantial improvements to such existing parks, when such development
is located in all, or a designed portion, of a floodplain.
The date the permit was issued for substantial improvement
and other proposed new development, provided the actual start of construction,
repair, reconstruction, rehabilitation, addition, placement, or other
improvement was within 180 days from the date of the permit and shall
be completed within 12 months after the date of issuance of the permit
unless a time extension is granted, in writing, by the Floodplain
Administrator. The "actual start" means either the first placement
of permanent construction of a structure on a site, such as the pouring
of slab or footings, the installation of piles, the construction of
columns, or any work beyond the stage of excavation; or the placement
of a manufactured home on a foundation. Permanent construction does
not include land preparation, such as clearing, grading, and filling;
nor does it include the installation of streets and/or walkways; nor
does it include excavation for a basement, footings, piers, or foundations
or the erection of temporary forms; nor does it include the installation
on the property of accessory buildings, such as garages or sheds not
occupied as dwelling units or not part of the main structure. For
a substantial improvement, the "actual start of construction" means
the first alteration of any wall, ceiling, floor, or other structural
part of a building, whether or not that alteration affects the external
dimensions of the building.
A walled and roofed building, including a gas or liquid storage
tank that is principally above ground, as well as a manufactured home.
The division or redivision of a lot, tract, or parcel of
land by any means into two or more lots, tracts, parcels, or other
divisions of land, including changes in existing lot lines, for the
purpose, whether immediate or future, of lease, partition by the court
for distribution to heirs or devisees, transfer of ownership or building
or lot development; provided, however that the subdivision by lease
of land for agricultural purposes into parcels of more than 10 acres,
not involving any new street or easement of access or any residential
dwelling, shall be exempted.
Damage from any cause sustained by a structure whereby the
cost of restoring the structure to its before-damaged condition would
equal or exceed 50% or more of the market value of the structure before
the damage occurred.
Any reconstruction, rehabilitation, addition, or other improvement
of a structure, the cost of which equals or exceed 50% of the market
value of the structure before the start of construction of the improvement.
This term includes structures which have incurred substantial damage,
regardless of the actual repair work performed. The term does not,
however, include either:
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to assure safe living conditions.
Any alteration of an historic structure, provided that the alteration
will not preclude the structure's continued designation as an historic
structure.
The statewide building code adopted by The Pennsylvania General
Assembly in 1999 applicable to new construction in all municipalities,
whether administered by the municipality, a third party or the Department
of Labor and Industry. Applicable to residential and commercial buildings,
the code adopted the International Residential Code (IRC) and the
International Building Code (IBC), by reference, as the construction
standard applicable with the state floodplain construction. For coordination
purposes, references to the above are made specifically to various
sections of the IRC and the IBC.
The failure of a structure or other development to be fully
compliant with the community's floodplain management regulations.
A structure or other development without the elevation certificate,
other certifications, or other evidence of compliance required in
44 CFR 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5)
is presumed to be in violation until such time as that documentation
is provided.
