The Legislature of the Commonwealth of Pennsylvania has, by
the passage of the Pennsylvania Flood Plain Management Act of 1978,
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 Borough Council
of the Schwenksville does hereby order as follows.
The intent of this article is to:
A. Protect areas of the floodplain necessary to contain floodwaters.
B. To permit only those uses in the floodplain that are compatible with
preserving natural conditions and stream flow.
C. Promote the general health, welfare, and safety of the community
by preventing development in areas prone to flooding.
D. Encourage the utilization of appropriate construction practices in
order to prevent or minimize flood damage in the future.
E. Minimize danger to public health by protecting water supply and natural
drainage.
F. Reduce financial burdens imposed on the community, its governmental
units, and its residents, by preventing excessive development in areas
subject to flooding.
G. Comply with federal and state floodplain management requirements.
This article supersedes any other conflicting provisions which
may be in effect in the Floodplain Conservation District. However,
any other article 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 article, the
more restrictive shall apply.
If any section, subsection, paragraph, sentence, clause, or
phrase of this article shall be declared invalid for any reason whatsoever,
such a decision shall not affect the remaining portions of the article,
which shall remain in full force and effect, and for this purpose
the provisions of this article are hereby declared to be severable.
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
or 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 Conservation District
or that land uses permitted within such areas will be free from flooding
or flood damages. This article shall not create liability on the part
of Schwenksville or any officer or employee thereof for any flood
damages that result from reliance on this article or any administrative
decision lawfully made there under.
For the purposes of this article, the words and terms used herein
shall be interpreted as follows. Unless specifically defined below,

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.
VIOLATION
The failure of a structure or other development to be fully
compliant with the community's flood plain 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.
The Floodplain Conservation District shall consist of the following
specific areas/districts:
A. The floodway area/district shall be those areas identified as floodway
on the FIRM as well as those floodway areas which have been identified
in other available studies or sources of information for 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.
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. No new construction or development shall be allowed, unless a permit
is obtained from the Department of Environmental Protection 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. The 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.
C. The A Area/District shall be the areas identified as an A Zone on
the FIRM included in the FIS prepared by FEMA and for which no one-percent-annual
chance flood elevations have been provided. For these areas, elevation
and floodway information from other federal, state, or other acceptable
source shall be used when available. Where other acceptable information
is not available, the elevation shall be determined by using the elevation
of a point on the boundary of the Floodplain Conservation District
which is nearest the construction site. In lieu of the above, the
Borough of Schwenksville 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.
D. Community identified flood hazard areas shall be those areas where
Schwenksville 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 Floodplain Conservation District may be revised or modified
by the Schwenksville Borough Council where studies or information
provided by a qualified agency or person documents the need for such
revision. However, prior to any such change, 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 by submitting technical or scientific
data.
Should a dispute concerning any identified floodplain boundary
arise, an initial determination shall be made by the Schwenksville
Planning Commission and any party aggrieved by this decision or determination
may appeal to the Borough 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.
The following uses are permitted by right in the Floodplain
Conservation District in compliance with the requirements of this
article:
A. Up to half of any required yard setback area on an individual residential
lot may extend into the Floodplain Conservation District, provided
such yards are not used for on-site sewage disposal systems or for
nonwire fences or other structure.
B. Open space uses that are primarily passive in character shall be
permitted to extend into the floodplain including:
1. Wildlife sanctuaries, nature preserves, forest preserves, fishing
areas, as well as passive areas of public parklands (including, but
not limited to, hiking, biking and bridle trails, parks, camps, picnic
areas, fishing sport or boating clubs, piers, docks, floats, or shelters
usually found in developed outdoor recreation areas, but no facilities
subject to damage by flooding).
2. Outdoor plant nursery or orchard in accordance with recognized soil
conservation practices.
3. Streambank stabilization.
4. Forestry operations, lumbering and reforestation practices as reviewed
by the Montgomery County Conservation District.
C. The following floodplain crossings are permitted, provided disturbance
to any existing woodlands and degradation of water quality are minimized
to the greatest extent practicable:
1. Agricultural crossings by farm vehicles and livestock.
2. Paved driveways serving uses such as single-family detached dwelling
units, roadways, recreational trails, railroads, and utilities as
long as the pavement used is pervious.
D. Agricultural uses conducted in compliance with methods prescribed
in the latest version of the Department of Environmental Protection's
Erosion and Sediment Pollution Control Manual.
E. Public sewer and/or water lines and public utility transmission lines
running along the corridor.
F. Development of elevated and flood-proofed buildings on brownfield sites in redevelopment areas encouraging economic revitalization, in compliance with §
176-1532.
Any use or activity not authorized within §
176-1513, herein, shall be prohibited within the Floodplain Conservation District and the following activities and facilities are specifically prohibited, except for as part of a redevelopment project in compliance with § 176-1513.F herein:
A. No new construction, alteration, or improvement of buildings and
any other type of permanent structure, including fences shall be permitted
in the floodway or the one-hundred-year floodplain.
B. Placement of fill within the one-hundred-year floodplain is prohibited.
C. No encroachment, alteration, or improvement of any kind shall be
made to any watercourse.
D. Clearing of all existing vegetation, except where such clearing is necessary to prepare land for a use permitted under §
176-1513, herein, and where the effects of these actions are mitigated by reestablishment of vegetation.
E. Use of fertilizers, pesticides, herbicides, and/or other chemicals
in excess of prescribed industry standards.
F. Roads or driveways, except where permitted as corridor crossings in compliance with §
176-1513, herein.
G. Motor or wheeled vehicle traffic in any area not designed to accommodate
adequately the type and volume.
I. Subsurface sewage disposal areas.
K. Stormwater basins, including necessary berms and outfall facilities.
The provisions of this article do not require any changes or improvements to be made to lawfully existing structures. However, when an improvement is made to any existing structure, the provisions of §
176-1516, and any applicable Schwenksville nonconforming use standards contained within the borough's zoning ordinance shall apply.
The following provisions shall apply whenever any improvement
is made to an existing structure located within any Floodplain Conservation
District:
A. No expansion or enlargement of an existing structure shall be allowed
within any floodway area that would cause any increase in the elevation
of the base flood elevation.
B. No expansion or enlargement of an existing structure shall be allowed
within any AE Area/District with floodway, as defined in § 176-1509.B,
which would, together with all other existing and anticipated development,
increase the BFE more than one foot at any point.
C. No expansion or enlargement of an existing structure shall be undertaken
in the direction of the streambank.
D. Any modification, alteration, reconstruction, or improvement, of
any kind to an existing structure, to an extent or amount of 50% or
more of its market value, shall constitute a substantial improvement
and shall be undertaken only in full compliance with the provisions
of this article.
E. Historic structures undergoing repair or rehabilitation that would
constitute a substantial improvement as defined in this article must
comply with all requirements that do not preclude the structure's
continued designation as an historic structure. Documentation that
a specific requirement herein will cause removal of the structure
from the National Register of Historic Places or the State Inventory
of Historic Places must be obtained from the Secretary of the Interior
or the State Historic Preservation Officer. Any exemption from the
ordinance requirements will be the minimum necessary to preserve the
historic character and design of the structure.
F. The above activity shall also address the requirements of the 34
Pa.Code, as amended, the 2009 IBC, and the 2009 IRC.
G. Any modification, alteration, reconstruction, or improvement of any
kind that meets the definition of "repetitive loss" shall be undertaken
only in full compliance with the provisions of this article.
If compliance with any of the requirements of this article would
result in an exceptional hardship to a prospective builder, developer
or landowner, the Zoning Hearing Board of Schwenksville may, upon
request, grant relief from the strict application of the requirements.
All subdivision proposals and development proposals containing
at least 50 lots or at least five acres, whichever is the lesser,
in flood hazard areas where base flood elevation data are not available,
shall be supported by hydrologic and hydraulic engineering analyses
that determine base flood elevations and floodway information. The
analyses shall be prepared by a licensed professional engineer in
a format required by FEMA for a conditional letter of map revision
or Letter of Map Revision.
Recreational vehicles in Zones AE must either:
A. Be on the site for fewer than 180 consecutive days; and
B. Be fully licensed and ready for highway use; or
C. Meet the permit requirements for manufactured homes in §
176-1520.
