These regulations, in conjunction with the Uniform Construction
Code, provide minimum requirements for development located in flood
hazard areas, including the subdivision of land and other developments;
site improvements and installation of utilities; placement and replacement
of manufactured homes; placement of recreational vehicles; new construction
and alterations, repair, reconstruction, rehabilitation or additions
of existing buildings and structures; substantial improvement of existing
buildings and structures, including repair of substantial damage;
installation of tanks; temporary structures and temporary or permanent
storage; Utility and Miscellaneous Group U buildings and structures;
and certain building work exempt from permit under the Uniform Construction
Code; and other buildings and development activities.
A.
The Township of Long Beach was accepted for participation in the
National Flood Insurance Program on May 26, 1970.
B.
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, most recent preliminary FEMA mapping and flood
studies, and Department 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 Long
Beach Township Municipal Building, 6805 Long Beach Boulevard, Brant
Beach, New Jersey 08008-3661. The following sources identify flood
hazard areas in this jurisdiction and must be considered when determining
the best available flood hazard data area:

Effective flood insurance study. Special Flood Hazard Areas (SFHAs)
identified by the Federal Emergency Management Agency in a scientific
and engineering report entitled Flood Insurance Study, Ocean County,
New Jersey (All Jurisdictions) dated September 26, 2006, revised on
June 20, 2018, and December 16, 2021, and the accompanying Flood Insurance
Rate Maps (FIRM) identified in Table 94-11B(1) whose effective date
is September 26, 2006 are hereby adopted by reference.

Federal best available information. The Township of Long Beach 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.

Flood Hazard Protection Area - Primary Frontal Dune (PFD). The Township of Long Beach hereby designates all lands in the primary frontal dune area which are designated as AO, Unshaded X, and Shaded X as a Flood Hazard Protection Area - Primary Frontal Dune (FHPA - PFD) after considering the most restrictive of the effective Flood Insurance Study and other federal best available information described in § 94-11 and any requirements for determining flood hazard areas as specified in N.J.A.C. 7:13. This FHPA is designated because of the erodibility of the underlying soil characteristics and the vulnerability of structures in these areas to erosion and scour if dunes and/or flood protection infrastructure seaward of these areas are breached.
(4)
Flood Hazard Protection Area A. The Township of Long Beach hereby designates all lands designated as AE 7 or less and any AO Zones not located within a primary frontal dune area which specify elevations aboveground surface that result in local design flood elevations less than eight feet not including freeboard as a Flood Hazard Protection Area A (FHPA - A) after considering the most restrictive of the effective Flood Insurance Study and other federal best available information described in § 94-11 and any requirements for determining flood hazard areas as specified in N.J.A.C. 7:13. This FHPA is designated because of the erodibility of the underlying soil characteristics and the vulnerability of structures in these areas to erosion and scour if dunes and/or flood protection infrastructure in these areas are breached.
(5)
Flood Hazard Protection Area V. The Township of Long Beach hereby designates all lands designated as VE 9 as a Flood Hazard Protection Area V (FHPA - V) after considering the most restrictive of the effective Flood Insurance Study and other federal best available information described in § 94-11 and any requirements for determining flood hazard areas as specified in N.J.A.C. 7:13. This FHPA is designated because of the erodibility of the underlying soil characteristics and the vulnerability of structures in these areas to erosion and scour if dunes and/or flood protection infrastructure in these areas are breached.
(6)
Flood Hazard Protection Area X. The Township of Long Beach hereby designates all lands designated as X Zones on the June 17, 2013 FIRM Map or any subsequent map and which are not located in the primary frontal dune area as a Flood Hazard Protection Area X (FHPA - X) after considering the most restrictive of the effective Flood Insurance Study and other federal best available information described in § 94-11 and any requirements for determining flood hazard areas as specified in N.J.A.C. 7:13. This FHPA is designated because of the erodibility of the underlying soil characteristics and the vulnerability of structures in these areas to erosion and scour if dunes and/or flood protection infrastructure in these areas are breached.
(7)
Other best available data. The Township of Long Beach shall utilize high water elevations from flood events, groundwater flooding areas, studies by federal or state agencies, or other information deemed appropriate by the Township of Long Beach. 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 § 94-11B(1) and (2), above. This information shall be used for floodplain regulation purposes only.
A.
The local design flood elevation (LDFE) is established in the flood hazard areas determined in § 94-11, above, using the best available flood hazard data sources, and the Flood Hazard Area Control Act minimum statewide elevation requirements for lowest floors in A, Coastal A, and V Zones, ASCE 24 requirements for critical facilities as specified by the building code, plus additional freeboard as specified by this chapter. At a minimum, the local design flood elevation shall be as follows:
(1)
For a delineated watercourse, the elevation associated with the best available flood hazard data area determined in § 94-11 above plus one foot or as described by N.J.A.C. 7:13 of freeboard; or
(2)
AO Zones. For Zone AO areas on the municipality's FIRM (or on
preliminary flood elevation guidance from FEMA) unless located within
the Flood Hazard Protection Area - Primary Frontal Dunes or a Flood
Hazard Protection Area - A, the local design flood elevation is determined
from the FIRM panel as the highest adjacent grade plus the depth number
specified plus one foot of freeboard. If no depth number is specified,
the local design flood elevation is three feet above the highest adjacent
grade.
(3)
Flood Hazard Protection Area - Primary Frontal Dune. For FHPA-PFD areas designated in § 94-11 in the primary frontal dune, no building or structure shall be erected or enlarged which has the lowest primary floor level elevated less than 21 feet nor more than 28 feet above the mean sea level as determined by the 1988 North American Vertical Datum. In no case shall the local design flood elevation in this area be lower than required by § 94-12A(1) or the elevation required by any state coastal zone management permit.
(4)
Flood Hazard Protection Area - A. For FHPA-A areas designated in § 94-11 with mapped elevations AE 7 or less and any mapped AO Zones not located within a primary frontal dune area which specify elevations above ground surface that result in local design flood elevations less than eight feet not including freeboard, the local design flood elevation shall be eight feet NAVD88 plus one foot of freeboard. In no case shall the local design flood elevation in this area be lower than required by § 94-12A(1).
(5)
Flood Hazard Protection Area - V. For FHPA-V areas designated in § 94-11 with mapped with mapped elevations VE 9 or less, the local design flood elevation on shall be 14 feet NAVD88 plus one foot of freeboard. In no case shall the local design flood elevation in this area be lower than required by § 94-12A(1).
[Amended 12-5-2022 by Ord. No. 22-23C]
(6)
Flood Hazard Protection Area - X. For FHPA-X areas designated in § 94-11 with mapped X Zones not in the primary frontal dune area, the local design flood elevation shall be the same as the nearest AE Zone elevation plus one foot of freeboard, provided that that AE Zone elevation is no lower than eight feet not including the required one foot of freeboard. In no case shall the local design flood elevation in this area be lower than required by § 94-12A(1).
(7)
Class IV Critical Facilities. For any proposed development of new
and substantially improved Flood Design Class IV Critical Facilities,
the local design flood elevation must be the higher of the 0.2% annual
chance (500-year) flood elevation or the flood hazard area design
flood elevation with an additional two feet of freeboard in accordance
with ASCE 24.
(8)
Class III Critical Facilities. For proposed development of new and
substantially improved Flood Design Class III Critical Facilities
in coastal high hazard areas, the local design flood elevation must
be the higher of the 0.2% annual chance (500-year) flood elevation
or the flood hazard area design flood elevation with an additional
one foot of freeboard in accordance with ASCE 24.
