The identified floodplain area shall be any
area of Riverside Borough subject to the one-hundred-year flood, which
is identified as Zone A (area of special flood hazard) in the Flood
Insurance Study (FIS) and the accompanying maps, or the most recent
revision thereof, as issued by the Federal Emergency Management Agency,
including all digital data developed as part of the Flood Insurance
Study.
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 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 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
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
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 one-hundred-year-flood elevations
have been provided. When available, information from other federal,
state, and other acceptable sources shall be used to determine the
one-hundred-year elevation, as well as a floodway area, if possible.
When no other information is available, the one-hundred-year elevation
shall be determined by using a point on the boundary of the identified
floodplain area which is nearest the construction site in question.
In lieu of the above, the municipality 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 by the Riverside Borough Council.
The identified floodplain area may be revised
or modified by the Borough of Riverside where studies or information
provided by a qualified agency or person documents the need for such
revision. However, prior to any such change, approval must be obtained
from the Federal Emergency Management Agency (FEMA).
Should a dispute concerning any identified floodplain
boundary arise, an initial determination shall be made by the designated
Building Permit Officer, and any party aggrieved by this decision
or determination may appeal to the Riverside Borough Council. The
burden of proof shall be on the appellant.
