[Ord. 482 (2015-04), 12/16/2015]
1. The identified floodplain area shall be those areas of Glen Rock
Borough which are subject to the base flood, which is identified as
Zone A (Area of Special Flood Hazard) in the Flood Insurance Study
(FIS) prepared for the Borough by the Federal Emergency Management
Agency (FEMA) dated December 16, 2015, and the accompanying Flood
Insurance Rate Maps (FIRM) and any subsequent revisions or amendments
are hereby adopted by Glen Rock Borough and declared to be a part
of this chapter thereof as issued by FEMA, including all digital data
developed as part of the Flood Insurance Study, and any other areas
for which independent studies by a professional engineer or other
qualified professional confirmed the areas to be inundated by the
one-hundred-year flood (base flood).
2. A map showing all areas considered to be subject to the base flood
is available for inspection at the Glen Rock Borough office.
[Ord. 482 (2015-04), 12/16/2015]
1. The identified floodplain area shall consist of the following specific
areas:
A. FW (Floodway Area): the areas identified as "Floodway" in the AE
Zone in the Flood Insurance Study prepared by the FEMA. The term shall
also include floodway areas which have been identified in other available
studies or sources of information for those floodplain areas where
no floodway has been identified in the Flood Insurance Study.
B. FF (Flood-Fringe Area): the remaining portions of the one-hundred-year
(base flood) floodplain in those areas identified as an AE Zone in
the Flood Insurance study where a floodway has been delineated. The
basis for the outermost boundary of this area shall be the one-hundred-year
flood (base flood) elevations as shown in the flood profiles contained
in the Flood Insurance Study.
C. FE (Special Floodplain Area): the areas identified as Zone AE in
the Flood Insurance Study, where one-hundred-year flood (base flood)
elevations have been provided, but no floodway has been delineated.
D. FA (General Floodplain Area): the areas identified as Zone A in the
FIS for which no base flood elevations have been provided. When available,
information from other federal, state, and other acceptable sources
shall be used to determine the base flood elevation, as well as a
floodway area, if possible. When no other information is available,
the base flood elevation shall be determined by using a point on the
boundary of the identified floodplain area which is nearest the construction
site in question.
2. In lieu of the above, the Borough 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 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.
[Ord. 482 (2015-04), 12/16/2015]
The identified floodplain area may be revised or modified by
Glen Rock Borough Council where studies or information provided by
a qualified agency or person documents the need for such revision.
However, prior to any such change to the Special Flood Hazard Area,
approval must be obtained from the Federal Emergency Management Agency
(FEMA) or any other federal agency with the power and authority to
revise the FIS and FIRM. 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 to the Special
Flood Hazard Area by submitting technical or scientific data.
[Ord. 482 (2015-04), 12/16/2015]
Should a dispute concerning any identified floodplain boundary
arise, an initial determination shall be made by the Planning Commission,
and if desired, with the assistance by any other appropriate agencies
and/or individuals (e.g., Zoning Officer, Borough Engineer, etc.),
and any party aggrieved by this decision or determination may appeal
to the Council. The burden of proof shall be on the appellant.
