[HISTORY: Adopted by the City Council of the City of Englewood 2-4-1986 by Ord. No.
86-01; amended in its entirety 7-23-2019 by Ord. No. 19-06. Subsequent amendments noted where applicable.]
The Legislature of the State of New Jersey has in N.J.S.A. 40:48-1
et seq. and N.J.S.A. 40:55D-1 et seq. delegated the responsibility
to local governmental units to adopt regulations designed to promote
the public health, safety, and general welfare of its citizenry.
A.
The flood hazard areas of the City of Englewood are subject to periodic
inundation which results in loss of life and property, health and
safety hazards, disruption of commerce and governmental services,
extraordinary public expenditures for flood protection and relief,
and impairment of the tax base, all of which adversely affect the
public health, safety, and general welfare.
B.
These flood losses are caused by the cumulative effect of obstructions
in areas of special flood hazard which increase flood heights and
velocities, and when inadequately anchored, damage uses in other areas.
Uses that are inadequately floodproofed, elevated or otherwise protected
from flood damage also contribute to the flood loss.
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 an
area 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 purposes, 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 meanings
they have in common usage and to give this chapter its most reasonable
application.
Areas subject to inundation by one-percent-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.

any existing easements, covenants, or deed restrictions. However,
where this chapter and other ordinances, easements, covenants, or
deed restrictions conflict or overlap, whichever imposes the more
stringent restrictions shall prevail.
In the interpretation and application of this chapter, all provisions
shall be:
The degree of flood protection required by this chapter is considered
reasonable for regulatory purposes and is based on scientific and
engineering considerations. Larger floods can and will occur on rare
occasions. Flood heights may be increased by man-made or natural causes.
This chapter does not imply that land outside the areas of special
flood hazard or uses permitted within such areas will be free from
flooding or flood damages. This chapter shall not create liability
on the part of the City of Englewood, any officer or employee thereof
or the Federal Insurance Administration for any flood damages that
result from reliance on this chapter or any administrative decision
lawfully made thereunder.
Nothing contained herein shall be construed so as to relieve
nor shall any approvals granted hereunder have the effect of relieving
an applicant for development from obtaining any and all New Jersey
Department of Environmental Protection permits or approvals otherwise
required by law.
A.
A development permit shall be obtained before construction or development begins, including placement of manufactured homes, within any area of special flood hazard established in § 222-7. Application for a development permit shall be made on forms furnished by the local administrator and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions, and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing.

F.
Interpretation of FIRM boundaries. The local administrator shall 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 § 222-16.
A.
Appeal procedure.
(1)
The Planning Board of the City of Englewood shall be designated as
the appeal board to hear and decide appeals and requests for variances
from the requirements of this chapter; provided, however, that with
respect to an appeal or a request for a variance concerning any application

as the appeal board.
(2)
The Planning Board shall hear and decide appeals when it is alleged
there is an error in any requirement, decision, or determination made
by the Construction Code Official in the enforcement or administration
of this chapter, and requests for variances from the requirements
of this chapter.
(3)
Hearings respecting such appeals or requests for variances shall
be conducted, and notice thereof provided, in accordance with the
provisions of N.J.S.A. 40:55D-10 and 40:55D-12.
(4)
Decisions rendered by the Planning Board shall be final, and any
further appeal therefrom shall be taken to the courts in accordance
with the applicable rules of court.
(5)
In passing upon such applications, the appeal board shall consider
all technical evaluations, all relevant factors, standards specified
in other sections of this chapter, and:
(a)
The danger that materials may be swept onto other lands to the
injury of others;
(b)
The danger to life and property due to flooding or erosion damage;
(c)
The susceptibility of the proposed facility and its contents
to flood damage and the effect of such damage on the individual owner;
(d)
The importance of the services provided by the proposed facility
to the community;
(e)
The necessity to the facility of a waterfront location, where
applicable;
(f)
The availability of alternative locations for the proposed use
which are not subject to flooding or erosion damage;
(g)
The compatibility of the proposed use with existing and anticipated
development;
(h)
The relationship of the proposed use to the Comprehensive Plan
and floodplain management program of that area;
(i)
The safety of access to the property in times of flood for ordinary
and emergency vehicles;
(j)

sediment transport of the floodwaters and the effects of wave action,
if applicable, expected at the site; and
(k)
The costs of providing governmental services during and after
flood conditions, including maintenance and repair of public utilities
and facilities such as sewer, gas, electrical, and water systems,
and streets and bridges.
(6)
Upon consideration of the factors of § 222-16A(5) and the purposes of this chapter, the appeal board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
(7)
The Construction Code Official shall maintain the records of all
appeal actions, including technical information, and report any variances
to the Federal Insurance Administration upon request.
B.
Conditions for variances.
(1)
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of 1/2 acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, provided that items in Subsection A(5)(a) through (k) in this § 222-16 have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
(2)
Variances may be issued for the repair or rehabilitation of historic
structures upon a determination that the proposed repair or rehabilitation
will not preclude the structure's continued designation as an
historic structure and the variance is the minimum necessary to preserve
the historic character and design of the structure.
(3)
Variances shall not be issued within any designated floodway if any
increase in flood levels during the base flood discharge would result.
(4)
Variances shall only by issued upon a determination that the variance
is the minimum necessary, considering the flood hazard, to afford
relief.
(5)
Variances shall only be issued upon:
(a)
A showing of good and sufficient cause;
(b)
A determination that failure to grant the variance would result
in exceptional hardship to the applicant; and
(c)
A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public as identified in § 222-16A(5), or conflict with existing local laws or ordinances.
(6)
Any applicant to whom a variance is granted shall be given written
notice that the structure will be permitted to be built with a lowest
floor elevation below the base flood elevation, and that the cost
of flood insurance will be commensurate with the increased risk resulting
from the reduced lowest floor elevation.
A.
General standards. In all areas of special flood hazard, compliance
with the applicable requirements of the Uniform Construction Code
(N.J.A.C. 5:23) and the following standards, whichever is more restrictive,
is required.

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 covering or devices, provided that they permit the automatic
entry and exit of floodwaters.
B.
Specific standards. In all areas of special flood hazard where base flood elevation data have been provided as set forth in § 222-7, Basis for establishing areas of special flood hazard, or in § 222-15B, Use of other base flood and floodway data, the following standards are required:

data elevation plus one foot, or as required by ASCE/SEI 24-14, Table
2-1;
[5]
The manufactured home chassis is supported by reinforced piers
or other foundation elements of at least equivalent strength that
are no less than 36 inches in height above grade and be securely anchored
to an adequately anchored foundation system to resist flotation, collapse,
and lateral movement.
C.
Floodways. Located within areas of special flood hazard established in § 222-7 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles, and erosion potential, the following provisions apply:
(1)
Encroachments, including fill, new construction, substantial improvements, and other development, are prohibited unless a technical evaluation demonstrates that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge. All encroachments require permits and/or waivers from the New Jersey Department of Environmental Protection. If this Subsection C(1) is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of § 222-17, Provisions for flood hazard reduction.
(2)
The placement of any manufactured homes, except in an existing manufactured
home park or existing manufactured home subdivision, is prohibited.
(3)
