This <br />area element, which must be the first area <br />present in each data category, is assigned a <br />single attribute code with major and minor <br />codes both equal to zero. <br /> <br />, <br /> <br />Zone V <br /> <br />This code identifies an area inundated <br />100-year flooding with velocity hazard <br />action); no BFEs have been determined. <br />shown by FIS symbol Al05. <br /> <br />by <br />(wave <br />It is <br /> <br />Zone VE <br /> <br />This code identifies an area inundated by <br />100-year flooding with velocity hazard (wave <br />action); BFEs have been determined (parameter <br />code 441 0---) and are usually expressed in <br />feet (descriptive code 440 0610) but are <br />expressed in meters (descriptive code <br />440 0611) for some communities. It is shown <br />by FIS symbol Al06. <br /> <br />Zone A <br /> <br />This code identifies an area inundated by <br />100-year flooding, for which no BFEs have <br />been determined.
