§ 81-15Designation of floodplain areas.
§ 81-16Changes in identification of
floodplain area delineations.
§ 81-17Disputes.
For the purposes of this chapter, the areas considered to be floodplain within the Township of Daugherty shall be those areas identified as being subject to the one-hundred-year flood in the Flood Insurance Study prepared for the Township of Daugherty by the Federal Insurance Administration, dated December 1, 1981.
A map showing all areas considered to be subject to the one-hundred-year flood is available for inspection at the Township offices. For the purposes of this chapter, the following nomenclature is used in referring to the various kinds of flood-prone areas:
FW (Floodway Area). The areas identified as "floodway" in the Flood Insurance Study prepared by the FIA.
FF (Flood-Fringe Area). The areas identified as "floodway fringe" in the Flood Insurance Study prepared by the FIA.
FA (General Floodplain Area). The areas identified as "approximate one-hundred-year floodplain" in the Flood Insurance Study prepared by the FIA.
The FW (Floodway Area) is delineated for the purposes of this chapter using the criteria that a certain area within the floodplain must be capable of carrying the waters of the one-hundred-year flood without increasing the water surface elevation of that flood more than one foot at any point. The areas included in this area are specifically defined in the Floodway Data Table contained in the above-referenced Flood Insurance Study and shown on the accompanying Flood Boundary and Floodway Map.
The FF (Flood-Fringe Area) shall be that area of the one-hundred-year floodplain not included in the floodway. The basis for the outermost boundary of this district shall be the one-hundred-year-flood elevations contained in the flood profiles of the above-referenced Flood Insurance Study and as shown on the accompanying Flood Boundary and Floodway Map.
The FA (General Floodplain Area) shall be that floodplain area for which no detailed flood profiles or elevations are provided. Such areas are shown on the maps accompanying the Flood Insurance Study prepared by the FIA. In determining the necessary elevations for the purposes of this chapter, other sources of data may be used, such as:
Corps of Engineers: Floodplain Information Reports.
United States Geological Survey: Flood-Prone Quadrangles.
United States Department of Agriculture, Natural Resources Conservation Service: County Soil Surveys (Alluvial Soils) or P.L. 566 Flood Information.
Pennsylvania Department of Environmental Protection: Flood Control Investigations.
Known high-water marks from past floods.
Other sources.
The areas considered to be floodplain may be revised or modified by the Township Supervisors where studies or information provided by a qualified agency or person documents the need or possibility for such revision.
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 Zoning Officer, and any party aggrieved by such decision may appeal to the Township Supervisors. The burden of proof shall be on the appellant.
