§ 68-20Description of Floodplain Areas.
§ 68-21Changes in identification of area.
§ 68-22Boundary disputes.
The identified floodplain area shall be those areas of Bristol Township, which are subject to the one-hundred-year flood, as identified in the Flood Insurance Study (FIS) dated May 18, 1999 and the accompanying maps prepared for Bristol Township by the Federal Emergency Management Agency (FEMA), or the most recent revision thereof.
The identified floodplain area shall consist of the following specific areas:
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.
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.
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.
FA (General Floodplain Area): the areas identified as Zone A in the Flood Insurance Study 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 applicant may 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 Bristol Township.
The identified floodplain area may be revised or modified by the Township Council 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 Insurance Administration (FIA).
Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Bristol Township Planning Commission and any party aggrieved by this decision or determination may appeal to the Township Council. The burden of proof shall be on the appellant.
