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 Norristown
Municipal Council does hereby adopt the following provisions pursuant
to the Pennsylvania Floodplain Management Act as follows:
A.
Intent. The intent of this chapter is to:
(1)
Protect areas of the floodplain necessary to contain floodwaters.
(2)
To permit only those uses in the floodplain that are compatible
with preserving natural conditions and stream flow.
(3)
Promote the general health, welfare, and safety of the community
by preventing development in areas prone to flooding.
(4)
Encourage the utilization of appropriate construction practices
in order to prevent or minimize flood damage in the future.
(5)
Minimize danger to public health by protecting water supply
and natural drainage.
(6)
Reduce financial burdens imposed on the community, its governmental
units, and its residents, by preventing excessive development in areas
subject to flooding.
(7)
Comply with federal and state floodplain management requirements.
B.
Applicability.
(1)
The Floodplain Conservation District is defined and established
as a district applicable to those areas of the Municipality of Norristown
subject to inundation by the waters of the one-hundred-year flood
as delineated on the Flood Insurance Rate Map (FIRM) for Montgomery
County, Pennsylvania, as prepared by the Federal Emergency Management
Agency, dated March 2, 2016, and subsequent revisions thereto. Said
floodplain areas shall consist of the following specific areas:
(a)
A and AE flood zones.
(b)
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:
(2)
In lieu of the above, the Municipality of Norristown 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, licensed in the Commonwealth of Pennsylvania, 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.
(3)
The Floodplain Conservation District shall be delineated according to FEMA's Flood Insurance Rate Map (FIRM) for the Municipality of Norristown, which is hereby made a part of this article, and additional area based on soils as described in § 320-331B(1)(b). The FIRM is available for inspection at the Municipal office.
(4)
The Floodplain Conservation District shall be deemed an overlay
on any zoning district now or hereafter applicable to any lot.
(5)
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 Municipality of Norristown unless
a permit has been obtained from the Floodplain Administrator.
(6)
A permit shall not be required for minor repairs to existing
buildings or structures.
C.
Abrogation and greater restrictions. This chapter supersedes any
other conflicting provisions which may be in effect in the Floodplain
Conservation District. 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 provision shall apply.
D.
Severability. 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 Ordinance, which shall remain in full force and effect, and
for this purpose the provisions of this chapter are hereby declared
to be severable.
E.
Warning and disclaimer of liability.
(1)
The degree of flood protection sought by the provisions of this
chapter 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 chapter
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.
(2)
This chapter shall not create liability on the part of the Municipality
of Norristown 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.
General. Unless specifically defined below, words and phrases used in this chapter shall be interpreted so as to give this chapter its most reasonable application. All definitions set forth in this § 320-332 are specific to this Floodplain article, and do not apply elsewhere.

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 exceeds 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 (or repetitive loss when a repetitive loss provision is used) regardless of the actual repair work performed. The term does not, however, include any project for improvement of a structure to correct existing violations of state or local health, sanitary, building 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. For alteration of historic structures, see § 320-334D(5).
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.
A.
Identification. The Floodplain Conservation District shall be any areas of the Municipality of Norristown classified as special flood hazard areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying Flood Insurance Rate Maps (FIRMs) dated March 2, 2016, 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. The Floodplain Conservation District shall also include areas with soils listed in § 320-331B(3), along with any community identified flood hazard areas. The above referenced FIS and FIRMs, and any subsequent revisions and amendments, are hereby adopted by Municipality of Norristown and declared to be a part of this chapter.
B.
Description and special requirements of the floodplain conservation
district. The Floodplain Conservation District shall consist of 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
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.
(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.
(2)
The AE Area/District shall be those areas identified as an AE
Zone on the FIRM included in the FIS prepared by FEMA and for which
base flood elevations have been provided.
(a)
In AE Area adjacent to the floodway shall be those areas identified
as 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.
(b)
No permit shall be granted for any construction, development,
use, or activity within any AE Area/District unless it is demonstrated
that the cumulative effect of the proposed development would not,
together with all other existing and anticipated development, increase
the BFE more than one foot at any point.
(3)
Community-identified flood hazard areas shall be those areas
where the Municipality of Norristown 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 appropriate
study methodologies.
(4)
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.
(a)
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 licensed in the Commonwealth of Pennsylvania
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.
Changes in identification of area. The Floodplain Conservation District
may be revised or modified by the Municipality of Norristown 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 the 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.
D.
Boundary disputes. Should a dispute concerning any identified floodplain
boundary arise, an initial determination shall be made by the Municipality
of Norristown Planning Commission and any party aggrieved by this
decision or determination may appeal to the Municipality of Norristown
Council. The burden of proof shall be on the appellant.
E.
Corporate 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.
A.
Uses permitted by right. The following uses are permitted by right
in the floodplain Conservation District in compliance with the requirements
of this article:
(1)
Up to half of any required yard setback area on an individual
residential lot may extend into the Floodplain Conservation District.
(3)
Forestry operations reviewed by the Montgomery County Conservation
District.
(4)
The following floodplain crossings are permitted, provided disturbance
to any existing woodlands and degradation of water quality are minimized
to the greatest extent practicable:
(5)
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. In the event that the
municipality has a Riparian Corridor Conservation District or similar
regulation, the more restrictive regulation shall apply.
(6)
Public sewer and/or water lines and public utility transmission
lines running along the corridor. Utility crossings shall be made
perpendicular to the direction of flow, or as near as practical.
B.
Uses prohibited in the Floodplain Conservation District. Any use or activity not authorized within § 320-334A, 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 § 320-334A(7) herein:
(1)
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.
(2)
New construction of buildings or placement of fill within the
one-hundred-year floodplain is prohibited.
(3)
No encroachment, alteration, or improvement of any kind shall
be made to any watercourse.
(4)
Clearing of all existing vegetation, except where such clearing is necessary to prepare land for a use permitted under § 320-334A, herein, and where the effects of these actions are mitigated by reestablishment of vegetation.
(5)
Use of fertilizers, pesticides, herbicides, and/or other chemicals
in excess of prescribed industry standards.
(6)
Roads or driveways, except where permitted as corridor crossings in compliance with § 320-334A, herein.

products that would be harmful to the environment or water.
C.
Nonconforming structures and uses in the Floodplain District. The provisions of this chapter 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 § 320-334D of this chapter shall apply.
D.
Improvements to existing structures in the Floodplain Conservation
District. The following provisions shall apply whenever any improvement
is made to an existing structure located within any Floodplain Conservation
District:
(1)
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.
(2)
No expansion or enlargement of an existing structure shall be allowed within any AE Area/District with floodway, as defined in § 320-333B(2), which would, together with all other existing and anticipated development, increase the BFE more than one foot at any point. Any expansion or enlargement of an existing structure shall be an elevation of one foot six inches above the base floor elevation.
(3)
No expansion or enlargement of an existing structure shall be
undertaken in the direction of the stream bank.
(4)
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 chapter.
(5)
Historic structures undergoing repair or rehabilitation that
would constitute a substantial improvement as defined in this chapter
must comply with all ordinance requirements that do not preclude the
structure's continued designation as an historic structure. Documentation
that a specific ordinance requirement 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.
(6)
The above activity shall also address the requirements of 34
Pa. Code, as amended, and the 2009 IBC and the 2009 IRC.
(7)
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 chapter.
A.
General. If compliance with any of the requirements of this chapter
would result in an exceptional hardship to a prospective builder,
developer or landowner, the Municipality of Norristown may, upon request,
grant relief from the strict application of the requirements.
B.
Variance procedures and conditions.
(1)
For a use other than those permitted in § 320-334, an application seeking approval by variance shall be forwarded to the Zoning Hearing Board along with required studies or information and the findings of the Zoning Officer.
(2)
No variance shall be granted for any construction, development,
use, or activity within any floodway area that would cause any increase
in the BFE.
(3)
No variance shall be granted for any construction, development,
use, or activity within any AE Area/District floodway that would,
together with all other existing and anticipated development, increase
the BFE more than one foot at any point.
(4)
No variance shall be granted for any of the other requirements pertaining specifically to development regulated by § 320-337D (pertaining to special technical requirements for activities requiring a special permit) or to development which may endanger human life [§ 320-336C(1)].
C.
Special requirements for subdivisions. 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.
D.
Special requirements for manufactured homes.
(1)
Within the Floodplain Conservation District, manufactured homes
shall be prohibited within the area measured 100 feet landward from
the top-of-bank of any watercourse.
(2)
Where permitted by variance within the Floodplain Conservation
District, all manufactured homes, and any improvements thereto, shall
be:
(a)
Placed on a permanent foundation.
(b)
Elevated so that the lowest floor of the manufactured home is
at least 1 1/2 feet above the base flood elevation.
(c)
Anchored to resist flotation, collapse, or lateral movement.
(d)
Have all ductwork and utilities including HVAC/heat pump elevated
to the regulatory flood elevation.
(3)
Installation of manufactured homes shall be done in accordance
with the manufacturers' installation instructions as provided by the
manufacturer. Where the applicant cannot provide the above information,
the requirements of Appendix E of the 2006 International Residential
Building Code or the U.S. Department of Housing and Urban Development's
Permanent Foundations for Manufactured Housing, 1984 Edition, draft
or latest revision thereto, shall apply and 34 Pa. Code, Chapters
401 through 405.
(4)
Consideration shall be given to the installation requirements
of the 2009 IBC, and the 2009 IRC or the most recent revisions thereto
and 34 Pa. Code, as amended, where appropriate and/or applicable to
units where the manufacturers' standards for anchoring cannot be provided
or were not established for the proposed installation.
F.
Variance conditions.
(1)
If granted, a variance shall involve only the least modification
necessary to provide relief.
(2)
In granting any variance, the Zoning Hearing Board shall attach
the reasonable conditions and safeguards outlined herein. These conditions
and safeguards are necessary in order to protect the public health,
safety, and welfare of the residents of the municipality.
(4)
In reviewing any request for a variance, the Zoning Hearing
Board shall consider, at a minimum, the following:
(a)
That there is good and sufficient cause, including:
[1]
That there are unique physical circumstances or conditions,
including irregularity, narrowness, or shallowness of lot size or
shape, or exceptional topographical or other physical conditions peculiar
to the particular property and that the unnecessary hardship is due
to such conditions and not the circumstances or conditions generally
created by the provisions of the zoning ordinance in the neighborhood
or district in which the property is located.
[2]
That because of such physical circumstances or conditions, there
is no possibility that the property can be developed in strict conformity
with the provisions of the zoning ordinance and that the authorization
of a variance is therefore necessary to enable the reasonable use
of the property.
[3]
That such unnecessary hardship has not been created by the appellant.
[4]
That the variance, if authorized, will not alter the essential
character of the neighborhood or district in which the property is
located, nor substantially or permanently impair the appropriate use
