The identified floodplain area shall be those areas of Carroll
Township which are subject to the one-hundred-year flood, which is
identified as Zone A (area of special flood hazard) in the Flood Insurance
Study (FIS) dated June 16, 2009, 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. 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 of 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 Township.
The identified floodplain area may be revised or modified by
the Board of Supervisors 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 Township Planning
Commission, and any party aggrieved by this decision or determination
may appeal to the Borough of Supervisors. The burden of proof shall
be on the appellant.
