A. The General Floodplain (FA) shall be that floodplain area for which no detailed flood elevations or floodway information is provided. Such areas are shown as Zone A on the maps accompanying the Flood Insurance Study prepared by the FEMA. For these areas, elevation and floodway information from other federal, state or other acceptable information shall be used when available. When such other acceptable information is not available, the elevation shall be determined by using the area which is nearest the construction site. In the General Floodplain (FA), the development and/or use of land shall be permitted in accordance with the regulations of the underlying district, provided that all such uses, activities and/or development shall be undertaken in strict compliance with the floodproofing and related provisions contained in all other applicable codes and ordinances.
