[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
The identified floodplain area shall be those areas of North Whitehall Township which are subject to the 100-year flood, as identified in the Flood Insurance Study (FIS) prepared for the Township by the Federal Emergency Management Agency (FEMA), dated July 16, 2004, and the accompanying maps prepared for the Township by FEMA, or the most recent revision thereof.
A. 
The identified floodplain area shall consist of the following specific areas:
(1) 
FW (floodway area).
(a) 
The areas identified as a 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) 
For purposes of this chapter, the floodway is based upon the criteria that a certain area within the floodplain would be capable of carrying the waters of the 100-year flood without increasing the water surface elevation of that flood more than one foot at any point.
(2) 
FF (flood-fringe area).
(a) 
The remaining portions of the 100-year floodplain in those areas identified as an AE Zone in the Flood Insurance Study, where a floodway has been delineated.
(b) 
The basis for the outermost boundary of this area shall be the 100-year-flood elevations as shown in the flood profiles contained in the Flood Insurance Study.
(3) 
FE (special floodplain area). The areas identified as Zone AE in the Flood Insurance Study, where 100-year-flood elevations have been provided, but no floodway has been delineated.
(4) 
FA (general floodplain area). The areas identified as Zone A in the FIS for which no 100-year-flood elevations have been provided. When available, information from other federal, state, and other acceptable sources shall be used to determine the 100-year elevation, as well as a floodway area, if possible. When no other information is available, the 100-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.
B. 
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.
A. 
The areas considered to be floodplain may be revised or modified by the Board of Supervisors where studies or information provided by a qualified agency or person documents the need or possibility for such revision.
B. 
No modification or revision of any floodplain area identified in the Flood Insurance Study prepared by the Federal Insurance Administration shall be made without prior approval from the Federal Insurance Administration.
Should a dispute arise concerning the identification of any floodplain area, an initial determination shall be made by the Planning Commission, and any party aggrieved by such decision may appeal to the Board of Supervisors. The burden of proof shall be on the appellant.
