The purpose of this chapter is to amend and replace Ordinance
Nos. 760 and 921 so as to ensure that the Borough's Floodplain Management
Ordinance complies with all federal regulations.
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. I)]
The Legislature of the State of New Jersey has, in N.J.S.A.
58:16A-1 et seq. and N.J.S.A. 40:55D-1 et seq. and N.J.S.A. 40:48-1
et seq., delegated the responsibility to local government units to
adopt regulations designed to promote the public health, safety, and
general welfare of its citizenry. The National Flood Insurance Act
of 1968 (Title 13 of the Housing and Urban Development Act of 1968)
requires that local municipalities adopt an ordinance and regulations
as contained herein.
It is the purpose of this chapter to promote the public health,
safety, and general welfare, and to minimize public and private losses
due to flood conditions in specific areas by provisions designed to:
A. Protect human life and health;
B. Minimize expenditure of public money for costly flood-control projects;
C. Minimize the need for rescue and relief efforts associated with flooding
and generally undertaken at the expense of the general public;
D. Minimize prolonged business interruptions;
E. Minimize damage to public facilities and utilities such as water
and gas mains, electric, telephone and sewer lines, streets and bridges
located in areas of special flood hazard;
F. Help maintain a stable tax base by providing for the sound use and
development of areas of special flood hazard so as to minimize future
flood-blight areas;
G. Ensure that potential buyers are notified that property is in areas
of special flood hazard; and
H. Ensure that those who occupy the areas of special flood hazard assume
responsibility for their actions.
In order to accomplish its purpose, this chapter includes methods
and provisions for:
A. Restricting or prohibiting uses which are dangerous to health, safety,
and property due to water or erosion hazards, or which result in damaging
increases in erosion or in flood heights or velocities;
B. Requiring that uses vulnerable to floods, including facilities which
serve such uses, be protected against flood damage at the time of
initial construction;
C. Controlling the alteration of natural floodplains, stream channels,
and natural protective barriers, which help accommodate or channel
floodwaters;
D. Controlling filling, grading, dredging, and other development which
may increase flood damage; and
E. Preventing or regulating the construction of flood barriers which
will unnaturally divert floodwaters or which may increase flood hazards
in other areas.
Unless specifically defined below, words or phrases used in
this chapter shall be interpreted so as to give them the meaning they
have in common usage and to give this chapter its most reasonable
application.
AH ZONE
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.
AO ZONE
Areas subject to inundation by 1% annual chance shallow flooding
(usually sheet flow on sloping terrain) where average depths are between
one feet and three feet.
APPEAL
A request for a review of the Borough Administrator's interpretation
of any provision of this chapter or a request for variance.
AREA OF SHALLOW FLOODING
A designated AO Zone on the Flood Insurance Rate Map (FIRM).
The base flood depths range from one to three feet; a clearly defined
channel does not exist; the path of flooding is unpredictable and
indeterminate; and velocity flow may be evident.
AREA OF SPECIAL FLOOD HAZARD
Land in the floodplain within a community subject to a 1%
or greater chance of flooding in any given year. It is shown on the
FIRM as Zone V, VE, V1-30, A, AO, A1-A30, AE, A99, or AH.
BASE FLOOD
A flood having a 1% chance of being equaled or exceeded in
any given year.
BASE FLOOD
The flood having a 1% chance of being equaled or exceeded
in any given year.
BASE FLOOD ELEVATION (BFE)

resulting from a flood that has a 1% or greater chance of being equaled
or exceeded in any given year.
BASEMENT
Any area of the building having its floor subgrade (below
ground level) on all sides.
BREAKAWAY WALL

A nonbasement building built, in the case of a building in
an area of special flood hazard, to have the top of the elevated floor,
elevated above the base flood elevation plus freeboard by means of
piling, columns (posts and piers), or shear walls parallel to the
flow of the water, and adequately anchored so as not to impair the
structural integrity of the building during a flood up to the magnitude
of the base flood. In an area of special flood hazard, "elevated building"
also includes a building elevated by means of fill or solid foundation
perimeter walls with openings sufficient to facilitate the unimpeded
movement of floodwaters.
EROSION
The process of gradual wearing away of land masses.

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.
FREEBOARD
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.

START OF CONSTRUCTION
For other than new construction or substantial improvements
under the coastal barrier resource act, P.L. 97-348, 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 a slab or footings, the installation of pilings, 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,
foot-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,

damage occurred.
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition, or other improvement
of a structure the cost of which 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:
A.
Any project for the 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;
or
B.
Any alteration of a historic structure, provided that the alteration
will not preclude the structure's continued designation as a historic
structure.
VARIANCE
A grant of relief from the requirements of this chapter which
permits the construction in a manner that would otherwise be prohibited
by this chapter.
VIOLATION
The failure of a structure or other development to be fully
compliant with this ordinance. A new or substantially improved 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), (e)(2), (e)(4), or (e)(5) is presumed to be in violation
until such time as that documentation is provided.
This chapter shall apply to all areas of special flood hazards
within the jurisdiction of the Borough of Emerson, County of Bergen,
State of New Jersey.
The areas of special flood hazard for the Borough of Emerson,
Community No. 340030, are identified and defined on the following

(a)
Verify and record the actual elevation (in relation to mean
sea level); and
(b)
Maintain the floodproofing certifications required in §
156-13B(2).
(3) Maintain for public inspection all records pertaining to the provisions
of this chapter.
D. Alteration of watercourses:
(1) Notify adjacent communities and the New Jersey Department of Environmental
Protection, Bureau of Flood Control and the Land Use Regulation Program
prior to any alteration or relocation of a watercourse, and submit
evidence of such notification to the Federal Insurance Administration.
(2) Require that maintenance is provided within the altered or relocated
portion of said watercourse so that the flood-carrying capacity is
not diminished.
E. Interpretation of FIRM boundaries: make interpretations, where needed, as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in §
156-16.
F. Substantial damage review.
(1) After an event resulting in building damages, assess the damage to
structures due to flood and nonflood causes.
(2) Record and maintain the flood and nonflood damage of substantial
damage structures and provide a letter of substantial damage determination
to the owner and the New Jersey Department of Environmental Protection,
Bureau of Flood Control.
(3) Ensure substantial improvements meet the requirements of §
156-18A, Specific standards, residential construction, §
156-18B, Specific standards, nonresidential construction and §
156-18C, Specific standards, manufactured homes.

fully enclosed areas below the lowest floor that are usable solely
for parking of vehicles, building access or storage in an area other
than a basement and which are subject to flooding shall be designed
to automatically equalize hydrostatic flood forces on exterior walls
by allowing for the entry and exit of floodwaters. Designs for meeting
this requirement must either be certified by a registered professional
engineer or architect or must meet or exceed the following minimum
criteria: a minimum of two openings in at least two exterior walls
of each enclosed area having a total net area of not less than one
square inch for every square foot of enclosed area subject to flooding
shall be provided. The bottom of all openings shall be no higher than
one foot above grade. Openings may be equipped with screens, louvers,
or other coverings or devices, provided that they permit the automatic
entry and exit of floodwaters.
In all areas of special flood hazard where base flood elevation data have been provided as set forth in §
156-8, Basis for establishing areas of special flood hazard, or in §
156-15B, Use of other base flood data, the following standards are required:
A. Residential construction.
(1) New construction and substantial improvement of any residential structure
located in an A or AE Zone shall have the lowest floor, including
basement together with the attendant utilities (including all electrical,
heating, ventilating, air-conditioning and other service equipment)

structures on slopes to guide floodwaters around and away from proposed
structures.
(2) Or:
(a)
Be floodproofed so that below the more restrictive, base flood
elevation plus one foot or as required by ASCE/SEI 24-14, Table 6-1,
the structure is watertight with walls substantially impermeable to
the passage of water;
(b)
Have structural components capable of resisting hydrostatic
and hydrodynamic loads and effects of buoyancy; and
(c)

Located within areas of special flood hazard established in §
156-8 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectile, and erosion potential, the following provisions apply:
A. Prohibit encroachments, including fill, new construction, substantial
improvements, and other development unless a technical evaluation
demonstrates that encroachments shall not result in any increase in
flood levels during the occurrence of the base flood discharge.
B. If §
156-19A is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of §§
156-17 through
156-19.
C. In all areas of special flood hazard in which base flood elevation
data has been provided and no floodway has been designated, the cumulative
effect of any proposed development, when combined with all other existing
and anticipated development, shall not increase the water surface
elevation of the base flood more than 0.2 foot at any point.
The regulations set forth in this chapter may contain references
to various uses not presently permitted within the Borough of Emerson.
Said references are not intended to indicate that said uses are now
permitted, and all uses prohibited by the Zoning Code of the Borough
of Emerson remain prohibited, and said code is not in any way amended
by this chapter.
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 chapter,
which shall remain in full force and effect, and for this purpose
the provisions of this chapter are hereby declared to be severable.
This chapter shall be effective on July 16, 2019, and shall
remain in force until modified, amended or rescinded by the Borough
of Emerson, Bergen County, New Jersey.
