(a) (1) The identified floodplain districts shall be those areas of the City of Williamsport classified as special flood hazard areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying Flood Insurance Rate Maps (FIRMs) dated 2-5-2014, and issued by the Federal Emergency Management Agency (FEMA) or the most recent revision thereof, including all digital data developed as part of the Flood Insurance Study.
(2) The above-referenced FIS and FIRMs and any subsequent revisions are hereby adopted by the City of Williamsport and made part of this article.
(b) The identified floodplain area shall be overlays to the existing underlying district as shown on the official Zoning Ordinance Map. As such, the provisions of the Floodplain District shall serve as a supplement to the underlying district provisions. Where this happens to be a conflict between the provisions or requirements for the floodplain districts and those of any overlying district, the most restrictive provisions pertaining to the floodplain shall apply. The basis for this district shall be as follows.
(1) The floodway district identified as a FW Zone on the FIRM included in the FIS prepared by FEMA represents the channel of a watercourse and the adjacent land area that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation by more than 1 foot at any point. This term shall also include floodway areas that have been identified in other available studies or sources of information for those Special Flood Hazard Areas where no floodway has been identified in the FIS.
(2) The AE District without floodway shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA and for which base flood elevations have been provided in the FIS, but no flood way has been delineated.
(3) 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 1% annual chance flood elevations have been provided. The city shall for these areas, elevation and floodway information accept the sources from federal, state or other acceptable sources available. Where other acceptable information is not available, the base flood elevations shall be determined by using the elevation point on the boundary of the identified floodplain area which is nearest the site in question.
