The Borough was accepted for participation in the National Flood
Insurance Program on February 15, 1978.
The National Flood Insurance Program (NFIP) floodplain management
regulations encourage that all Federal, State, and local regulations
that are more stringent than the minimum NFIP standards take precedence
in permitting decisions. The FHACA requires that the effective Flood
Insurance Rate Map (FIRM), most recent preliminary FEMA mapping and
flood studies, and NJDEP delineations be compared to determine the
most restrictive mapping. The FHACA also regulates unstudied flood
hazard areas in watersheds measuring 50 acres or greater in size and
most riparian zones in New Jersey. Because of these higher standards,
the regulated flood hazard area in New Jersey may be more expansive
and more restrictive than the FEMA Special Flood Hazard Area. Maps
and studies that establish flood hazard areas are on file at the Borough
of Hopewell Municipal Building, 88 East Broad Street, Hopewell, NJ
08525.
The following sources identify flood hazard areas in this jurisdiction
and must be considered when determining the Best Available Flood Hazard
Data Area:
1.
Effective Flood Insurance Study. Special Flood Hazard Areas (SFHAs)
identified by FEMA in a scientific and engineering report entitled
"Flood Insurance Study, Mercer County, New Jersey (All Jurisdictions)"
dated July 20, 2016 and the accompanying FIRMs identified in Table
14-2.2(a) whose effective date is July 20, 2016 are hereby adopted

Federal Best Available Information. Hopewell Borough shall utilize
Federal flood information as listed in the table below that provides
more detailed hazard information, higher flood elevations, larger
flood hazard areas, and results in more restrictive regulations. This
information may include but is not limited to preliminary flood elevation
guidance from FEMA (such as Advisory Flood Hazard Area Maps, Work
Maps or Preliminary FIS and FIRM). Additional Federal Best Available
studies issued after the date of this chapter must also be considered.
These studies are listed on FEMA's Map Service Center. This information
shall be used for floodplain regulation purposes only.

Other Best Available Data. The Borough shall utilize high water elevations
from flood events, groundwater flooding areas, studies by federal
or state agencies, or other information deemed appropriate by the
Borough. Other "best available information" may not be used which
results in less restrictive flood elevations, design standards, or
smaller flood hazard areas than the sources described in Tables 14-2.2(a)
and (b), above. This information shall be used for floodplain regulation
purposes only.
4.
State Regulated Flood Hazard Areas. For State regulated waters, the NJDEP identifies the flood hazard area as the land, and the space above that land, which lies below the "Flood Hazard Area Design Flood Elevation", as defined in § 14-9, and as described in the New Jersey Flood Hazard Area Control Act at N.J.A.C. 7:13. A FHACA flood hazard area exists along every regulated water that has a drainage area of 50 acres or greater. Such area may extend beyond the boundaries of the Special Flood Hazard Areas (SFHAs) as identified by FEMA. The following is a list of New Jersey State studied waters in this community under the FHACA, and their respective map identification numbers.

Where flood hazard areas are delineated on the effective or preliminary
FIRM and base flood elevation data have not been provided, the applicant
shall consult with the Floodplain Administrator to determine whether
to:
1.
Use the Approximation Method (Method 5) described in N.J.A.C. 7:13
in conjunction with Appendix 1 of the FHACA to determine the required
flood elevation.
2.
Obtain, review, and reasonably utilize data available from a Federal,
State or other source when those data are deemed acceptable to the
Floodplain Administrator to reasonably reflect flooding conditions.
3.
Determine the base flood elevation in accordance with accepted hydrologic
and hydraulic engineering techniques according to Method 6 as described
in N.J.A.C. 7:13. Such analyses shall be performed and sealed by a
licensed professional engineer.
Studies, analyses, and computations shall be submitted in sufficient
detail to allow review and approval by the Floodplain Administrator
prior to Floodplain Development Permit issuance. The accuracy of data
submitted for such determination shall be the responsibility of the

As applicable to the location and nature of the proposed development
activity, and in addition to the requirements of this section, the
applicant shall have the following analyses signed and sealed by a
licensed professional engineer for submission with the plan and construction
documents:
1.
For development activities proposed to be located in a regulatory floodway, a floodway encroachment analysis that demonstrates that the encroachment of the proposed development will not cause any increase in base flood elevations; where the applicant proposes to undertake development activities that do increase base flood elevations, the applicant shall submit such analysis to FEMA as specified in § 14-5.4 of these regulations and shall submit the Conditional Letter of Map Revision, if issued by FEMA, with the plan and construction documents.
2.
For development activities proposed to be located in a riverine flood
hazard area where base flood elevations are included in the FIS or
FIRM but floodways have not been designated, hydrologic and hydraulic
analyses that demonstrate that the cumulative effect of the proposed
development, when combined with all other existing and anticipated
flood hazard area encroachments will not increase the base flood elevation
more than 0.2 feet at any point within the jurisdiction. This requirement
does not apply in isolated flood hazard areas not connected to a riverine
flood hazard area or in flood hazard areas identified as Zone AO or
Zone AH.
3.
For alteration of a watercourse, an engineering analysis prepared in accordance with standard engineering practices which demonstrates that the flood-carrying capacity of the altered or relocated portion of the watercourse will not be decreased, and certification that the altered watercourse shall be maintained, neither increasing nor decreasing the channel's flood-carrying capacity. The applicant shall submit the analysis to FEMA as specified in § 14-5.4 of these regulations. The applicant shall notify the chief executive officer of all affected adjacent jurisdictions, the NJDEP's Bureau of Flood Engineering and the Division of Land Resource Protection; and shall provide documentation of such notifications.

Elevation of flooding having a 1% annual chance of being
equaled or exceeded in a given year which is also referred to as the
Base Flood Elevation.
Elevation of flooding having a 0.2% annual chance of being
equaled or exceeded in a given year.
Areas of Special Flood Hazard in which the elevation of the
surface water resulting from a flood that has a 1% annual chance of
equaling or exceeding the Base Flood Elevation (BFE) in any given
year shown on the FIRM zones A, AE, AH, A1-A30, AR, AR/A, AR/AE, AR/A1-A30,
AR/AH, and AR/AO.
Areas subject to inundation by 1%-annual-chance shallow flooding
(usually areas of ponding) where average depths are between one and
three feet. Base Flood Elevations (BFEs) derived from detailed hydraulic
analyses are shown in this zone.
Areas subject to inundation by 1%-annual-chance shallow flooding
(usually sheet flow on sloping terrain) where average depths are between
one and three feet.
Accessory structures are also referred to as appurtenant
structures. An accessory structure is a structure which is on the
same parcel of property as a principal structure and the use of which
is incidental to the use of the principal structure. For example,
a residential structure may have a detached garage or storage shed
for garden tools as accessory structures. Other examples of accessory
structures include gazebos, picnic pavilions, boathouses, small pole
barns, storage sheds, and similar buildings.
A structure used solely for agricultural purposes in which
the use is exclusively in connection with the production, harvesting,
storage, drying, or raising of agricultural commodities, including
the raising of livestock. Communities must require that new construction
or substantial improvements of agricultural structures be elevated
or floodproofed to or above the Base Flood Elevation (BFE) as any
other nonresidential building. Under some circumstances it may be
appropriate to wet-floodproof certain types of agricultural structures
when located in wide, expansive floodplains through issuance of a
variance. This should only be done for structures used for temporary
storage of equipment or crops or temporary shelter for livestock and
only in circumstances where it can be demonstrated that agricultural
structures can be designed in such a manner that results in minimal
damage to the structure and its contents and will create no additional
threats to public safety. New construction or substantial improvement
of livestock confinement buildings, poultry houses, dairy operations,
similar livestock operations and any structure that represents more
than a minimal investment must meet the elevation or dry-floodproofing
requirements of 44 CFR 60.3(c)(3).
A dam, impoundment, channel relocation, change in channel
alignment, channelization, or change in cross-sectional area of the
channel or the channel capacity, or any other form of modification
which may alter, impede, retard or change the direction and/or velocity
of the riverine flow of water during conditions of the base flood.
A designated Zone AO, AH, AR/AO or AR/AH on a community's
FIRM with a 1% or greater annual chance of flooding to an average
depth of one to three feet where a clearly defined channel does not
exist, where the path of flooding is unpredictable, and where velocity
flow may be evident. Such flooding is characterized by ponding or
sheet flow.

Any type of wall subject to flooding that is not required
to provide structural support to a building or other structure and
that is designed and constructed such that, below the Local Design
Flood Elevation, it will collapse under specific lateral loads such
that (a) it allows the free passage of floodwaters, and (b) it does
not damage the structure or supporting foundation system.
Per the FHACA, "Building" means a structure enclosed with
exterior walls or fire walls, erected and framed of component structural
parts, designed for the housing, shelter, enclosure, and support of
individuals, animals, or property of any kind. A building may have
a temporary or permanent foundation. A building that is intended for
regular human occupation and/or residence is considered a habitable
building.
A Conditional Letter of Map Revision (CLOMR) is FEMA's
comment on a proposed project that would, upon construction, affect
the hydrologic or hydraulic characteristics of a flooding source and
thus result in the modification of the existing regulatory floodway,
the effective Base Flood Elevations (BFEs), or the Special Flood Hazard
Area (SFHA). A CLOMR does not revise an effective NFIP map; rather,
it indicates whether the project, if built as proposed, would be recognized
by FEMA. FEMA charges a fee for processing a CLOMR to recover the
costs associated with the review that is described in the Letter of
Map Change (LOMC) process. Building permits cannot be issued based
on a CLOMR, because a CLOMR does not change the NFIP map.
Per the FHACA, "Critical Building" means that:
It is essential to maintaining continuity of vital government
operations and/or supporting emergency response, sheltering, and medical
care functions before, during, and after a flood, such as a hospital,
medical clinic, police station, fire station, emergency response center,
or public shelter; or
It serves large numbers of people who may be unable to leave
the facility through their own efforts, thereby hindering or preventing
safe evacuation of the building during a flood event, such as a school,
college, dormitory, jail or detention facility, day care center, assisted
living facility, or nursing home.
Any manmade change to improved or unimproved real estate,
including but not limited to, buildings or other structures, tanks,
temporary structures, temporary or permanent storage of materials,
mining, dredging, filling, grading, paving, excavations, drilling
operations and other land-disturbing activities.
A combination of measures that results in a non-residential
structure, including the attendant utilities and equipment as described
in the latest version of ASCE 24, being watertight with all elements
substantially impermeable and with structural components having the
capacity to resist flood loads.
A building that has no basement and that has its lowest elevated
floor raised above ground level by foundation walls, shear walls,
posts, piers, pilings, or columns.
An administrative tool of the National Flood Insurance Program
(NFIP) that can be used to provide elevation information, to determine
the proper insurance premium rate, and to support an application for
a Letter of Map Amendment (LOMA) or Letter of Map Revision based on
fill (LOMR-F).
The placement of fill, excavation, buildings, permanent structures
or other development into a flood hazard area which may impede or
alter the flow capacity of riverine flood hazard areas.
The federal agency responsible for administering the NFIP.
Any publication authored or referenced by FEMA related to
building science, building safety, or floodplain management related
to the National Flood Insurance Program (NFIP). Publications shall
include but are not limited to technical bulletins, desk references,

Per the FHACA, the peak water surface elevation that will
occur in a water during the flood hazard area design flood. This elevation
is determined via available flood mapping adopted by the State, flood
mapping published by FEMA (including effective flood mapping dated
on or after January 31, 1980, or any more recent advisory, preliminary,
or pending flood mapping; whichever results in higher flood elevations,
wider floodway limits, greater flow rates, approximation, or calculation
pursuant to the Flood Hazard Area Control Act Rules at N.J.A.C. 7:13-3.1
through 7:13-3.6 and is typically higher than FEMA's base flood
elevation. A water that has a drainage area measuring less than 50
acres does not possess, and is not assigned, a flood hazard area design
flood elevation.

A general and temporary condition of partial or complete inundation
of normally dry land areas from:
The overflow of inland or tidal waters.
The unusual and rapid accumulation or runoff of surface waters
from any source.
Mudslides (i.e. mudflows) which are proximately caused by flooding
as defined in paragraph a2 of this definition and are akin to a river
or liquid and flowing mud on the surfaces of normally dry land areas,
as when earth is carried by a current of water and deposited along
the path of the current.
The collapse or subsidence of land along the shore of a lake
or other body of water as a result of erosion or undermining caused
by waves or currents of water exceeding anticipated cyclical levels
or suddenly caused by an unusually high water level in a natural body

of nature, such as flash flood or an abnormal tidal surge, or by some
similarly unusual and unforeseeable event which results in flooding
as defined in paragraph a1 of this definition.
The provisions of this Chapter 14, in combination with the provisions of the UCC and FHACA which provide standards for the purpose of flood damage prevention and reduction.
Any land area susceptible to being inundated by water from
any source. See "flood or flooding."

floodproofing certificate is required with the Floodplain Development
Permit application submitted under these regulations.
The channel of a river or other watercourse and the adjacent
land areas that must be reserved in order to discharge the base flood
without cumulatively increasing the water surface elevation more than
0.2 foot.
A factor of safety usually expressed in feet above a flood
level for purposes of floodplain management. "Freeboard" tends to
compensate for the many unknown factors that could contribute to flood
heights greater than the height calculated for a selected size flood
and floodway conditions, such as wave action, bridge openings, and
the hydrological effect of urbanization of the watershed.
A use that cannot perform its intended purpose unless it
is located or carried out in close proximity to water, including only
docking facilities, port facilities necessary for the loading or unloading
of cargo or passengers, and shipbuilding and ship repair facilities.
The term does not include long-term storage or related manufacturing
facilities.
Pursuant to the FHACA Rules (N.J.A.C. 7:13), means a building
that is intended for regular human occupation and/or residence. Examples
of a habitable building include a single-family home, duplex, multi-residence
building, or critical building; a commercial building such as a retail
store, restaurant, office building, or gymnasium; an accessory structure
that is regularly occupied, such as a garage, barn, or workshop; mobile
and manufactured homes, and trailers intended for human residence,
which are set on a foundation and/or connected to utilities, such
as in a mobile home park (not including campers and recreational vehicles);
and any other building that is regularly occupied, such as a house
of worship, community center, or meeting hall, or animal shelter that
includes regular human access and occupation. Examples of a non-habitable
building include a bus stop shelter, utility building, storage shed,
self-storage unit, construction trailer, or an individual shelter
for animals such as a doghouse or outdoor kennel.
For purposes of these regulations only, hardship shall refer
to the exceptional hardship that would result from a failure to grant
the requested variance, as said term is defined herein. A hardship
shall be exceptional, unusual, and peculiar to the property involved.
Mere economic or financial hardship alone shall not qualify as a hardship.
Inconvenience, aesthetic considerations, physical handicaps, personal
preferences, or the disapproval of one's neighbors likewise shall
not qualify as a hardship. A problem or concern that can be resolved
through other means without granting a variance, even if the alternative
is more expensive, or requires the property owner to build elsewhere
or put the parcel to a different use than originally intended, shall
not be deemed a hardship.
The highest natural elevation of the ground surface prior
to construction next to the proposed or existing walls of a structure.
Any structure that is:
Listed individually in the National Register of Historic Places
(a listing maintained by the Department of Interior) or preliminarily
determined by the Secretary of the Interior as meeting the requirements
for individual listing on the National Register;
Certified or preliminarily determined by the Secretary of the
Interior as contributing to the historical significance of a registered
historic district or a district preliminarily determined by the Secretary
to qualify as a registered historic district;
Individually listed on a State inventory of historic places
in States with historic preservation programs which have been approved
by the Secretary of the Interior; or
Individually listed on a local inventory of historic places

A Letter of Map Amendment (LOMA) is an official amendment,
by letter, to an effective National Flood Insurance Program (NFIP)
map that is requested through the Letter of Map Change (LOMC) process.
A LOMA establishes a property's location in relation to the Special
Flood Hazard Area (SFHA). LOMAs are usually issued because a property
has been inadvertently mapped as being in the floodplain but is actually
on natural high ground above the base flood elevation. Because a LOMA
officially amends the effective NFIP map, it is a public record that
the Borough must maintain. Any LOMA shall be noted on the Borough's
master flood map and filed by panel number in an accessible location.
Fill, Letters of Map Revision, Letters of Map Revision-Fill,
and Letters of Map Amendment which are requested through the LOMC
process.
A Letter of Map Revision Based on Fill (LOMR-F) is FEMA's
modification of the Special Flood Hazard Area (SFHA) shown on the
FIRM based on the placement of fill outside the existing regulatory
floodway may be initiated through the Letter of Map Change (LOMC)
Process. Because a LOMR-F officially revises the effective FIRM, it
is a public record that the Borough must maintain. Any LOMR-F shall
be noted on the Borough's master flood map and filed by panel
number in an accessible location.
A Letter of Map Revision (LOMR) is FEMA's modification
to an effective FIRM. Letter of Map Revisions are generally based
on the implementation of physical measures that affect the hydrologic
or hydraulic characteristics of a flooding source and thus result
in the modification of the existing regulatory floodway, the effective
Base Flood Elevations (BFEs), or the Special Flood Hazard Area (SFHA).
The LOMR officially revises the FIRM and sometimes the Flood Insurance
Study (FIS) report, and when appropriate, includes a description of
the modifications. The LOMR is generally accompanied by an annotated
copy of the affected portions of the FIRM or FIS report. Because a
LOMR officially revises the effective NFIP map, it is a public record
that the Borough must maintain. Any LOMR shall be noted on the Borough's
master flood map and filed by panel number in an accessible location.
Licensed design professional shall refer to either a New
Jersey Licensed Professional Engineer licensed by the New Jersey State
Board of Professional Engineers and Land Surveyors or a New Jersey
Licensed Architect licensed by the New Jersey State Board of Architects.
A licensed professional engineer shall refer to individuals
licensed by the New Jersey State Board of Professional Engineers and

In no circumstances shall a project's LDFE be lower than a permit-specified
Flood Hazard Area Design Flood Elevation or a valid NJDEP Flood Hazard
Area Verification Letter plus the freeboard as required in ASCE 24
and the effective FEMA Base Flood Elevation.
The lowest point of ground, patio, or sidewalk slab immediately
next a structure, except in AO Zones where it is the natural grade
elevation.
In A Zones, the lowest floor is the top surface of the lowest
floor of the lowest enclosed area (including basement). An unfinished

building access or storage in an area other than a basement is not
considered a building's lowest floor provided that such enclosure
is not built so as to render the structure in violation of other applicable
non-elevation design requirements of these regulations.
A structure that is transportable in one or more sections,
eight feet or more in width and greater than 400 square feet, built
on a permanent chassis, designed for use with or without a permanent
foundation when attached to the required utilities, and constructed
to the Federal Manufactured Home Construction and Safety Standards

willing buyer and a willing seller, neither party being under compulsion
to buy or sell and both having reasonable knowledge of relevant facts.
As used in these regulations, the term refers to the market value
of buildings and structures, excluding the land and other improvements
on the parcel. Market value shall be determined by one of the following
methods (1) Actual Cash Value (replacement cost depreciated for age
and quality of construction), (2) tax assessment value adjusted to
approximate market value by a factor provided by the Property Appraiser,
or (3) established by a qualified independent appraiser.
Structures for which the start of construction commenced
on or after the effective date of the first floodplain regulation
adopted by the Borough; includes any subsequent improvements to such
structures. New construction includes work determined to be a substantial
improvement.
Pursuant to ASCE 24, any building or structure or portion
thereof that is not classified as residential.
This term refers to types of work excluded from construction
permitting under N.J.A.C. 5:23, published in the March 5, 2018 New
Jersey Register. Some of these types of work must be considered in
determinations of substantial improvement and substantial damage in
regulated floodplains under 44 CFR 59.1. These types of work include
but are not limited to replacements of roofing, siding, interior finishes,
kitchen cabinets, plumbing fixtures and piping, HVAC and air conditioning

The Start of Construction is as follows:
For other than new construction or substantial improvements,
this is the date the building permit was issued, provided that the
actual start of construction, repair, rehabilitation, addition, placement
or other improvement was within 180 days of the permit date. The actual
start means either the first placement of permanent construction of
a building on site, such as the pouring of a slab or footing, the
installation of piles, the construction of columns or any work beyond
the stage of excavation; or the placement of a manufactured (mobile)
home on a foundation. For a substantial improvement, 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.
For the purposes of determining whether proposed construction
must meet new requirements when National Flood Insurance Program (NFIP)
maps are issued or revised and Base Flood Elevation's (BFEs)
increase or zones change, the Start of Construction includes substantial
improvement, and means the date the building permit was issued, provided
the actual start of construction, repair, reconstruction, rehabilitation,
addition placement, or other improvement was within 180 days of the
permit date. 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. Such development must also be permitted
and must meet new requirements when National Flood Insurance Program
(NFIP) maps are issued or revised and Base Flood Elevation's
(BFEs) increase or zones change.
|
|
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, a manufactured home, or a gas
or liquid storage tank that is principally above ground.
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before damaged condition would
equal or exceed 50% 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,"
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 officer and
which are the minimum necessary to assure safe living conditions;
or
Any alteration of a "historic structure," provided that the
alteration will not preclude the structure's continued designation
as a "historic structure."
Buildings and structures of an accessory character and miscellaneous
structures not classified in any special occupancy, as described in
ASCE 24.
A grant of relief from the requirements of these regulations
which permits construction in a manner otherwise prohibited by these
regulations where specific enforcement would result in a hardship
as that term is defined in this chapter. The term "variance" as defined
herein shall not be deemed to refer to variances granted pursuant
to and governed by the Municipal Land Use Law, N.J.S.A. 40:55D-1 et
seq.
The failure to comply with any provision of this chapter
shall constitute a violation hereof. A violation shall include, but
not be limited to, a development that is not fully compliant with
these regulations or the flood provisions of the building code. In
addition, a structure or other development without the required Floodplain
Development Permit, elevation certificate, other certifications, or
other evidence of compliance required in these regulations is presumed
to be in violation until such time as that documentation is provided.
The height, in relation to the North American Vertical Datum
(NAVD) of 1988, or other datum, where specified, of floods of various
magnitudes and frequencies in the flood plains of riverine areas.
A river, creek, stream, channel, or other topographic feature
in, on, through, or over which water flows at least periodically.
A floodproofing method that relies on the use of flood damage
resistant materials and construction techniques in areas of a structure
that are below the Local Design Flood Elevation by intentionally allowing
them to flood. The application of wet floodproofing as a flood protection
technique under the National Flood Insurance Program (NFIP) is limited
to enclosures below elevated residential and non-residential structures
and to accessory and agricultural structures that have been issued
variances by the community.
