The identified floodplain area shall consist of the following
specific areas/districts:
A. The A Area/District shall be those areas identified as an A Zone
on the FIRM included in the FIS prepared by FEMA and for which no
base flood elevations have been provided. For these areas, elevation
and floodway information from other federal, state, or other acceptable
source shall be used when available. Where other acceptable information
is not available, the base flood elevation shall be determined by
hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic
analyses shall be undertaken only by registered 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 Borough.
B. For areas adjoining streams, ponds, and lakes not included in the
FIS prepared by FEMA, the applicant shall be required to determine
the elevation and area of the floodplain with hydrologic and hydraulic
engineering techniques. Hydrologic and hydraulic analyses shall be
undertaken only by registered 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 Borough. All areas
inundated by the one-hundred-year flood shall be included in the floodplain
area.
The identified floodplain area may be revised or modified by the Borough Council where studies or information provided by a qualified agency or person document the need for such revision. However, prior to any such change within the A Area/District, approval must be obtained from FEMA. Additionally, as soon as practicable, but not later than six months after the date such information becomes available, FEMA shall be notified of the changes by submission of technical or scientific data. Refer to §
174-24B for situations where FEMA notification is required.
Should a dispute concerning any identified floodplain boundary
arise, an initial determination shall be made by the Floodplain Administrator,
and any party aggrieved by this decision or determination may appeal
to the Zoning Hearing Board. The burden of proof shall be on the appellant.
Prior to development occurring in areas where annexation or
other corporate boundary changes are proposed or have occurred, the
Borough shall review flood hazard data affecting the lands subject
to boundary changes. The Borough shall adopt and enforce floodplain
regulations in areas subject to annexation or corporate boundary changes
which meet or exceed those in 44 CFR 60.3.
