(m) "Flood Insurance Rate Map (FIRM)" means an official map on which the Federal <br />Emergency Management. Agency or the U.S. Department of Housing and Urban Development <br />has delineated the areas of special flood hazazd. <br />(n) "Flood Insurance Risk Zones" means zone designations on FHBMs and FIRMS that indicate <br />the magnitude of the flood hazazd in specific areas of a community. Following are the zone <br />definitions: <br />Zone A: <br />Special flood hazard areas inundated by the 100-year flood; base flood elevations are not <br />determined. <br />Zones Al-30 and Zone AE: <br />Special flood hazard areas inundated by the 100-yeaz flood; base flood elevations aze <br />determined. <br />Zone AO: <br />Special flood hazard areas inundated by the 100-year flood; with flood depths of 1 to 3 <br />feet (usually sheet flow on sloping terrain); average depths aze determined. <br />Zone AH: <br />Special flood hazard areas inundated by the 100-year flood; flood depths of 1 to 3 feet <br />(usually areas of ponding); base flood elevations are determined. <br />Zone A99: <br />Special flood hazazd areas inundated by the 100-year flood to be protected from the 100- <br />year flood by a Federal flood protection system under construction; no base flood <br />elevations are determined. <br />Zone B and Zone X (shaded <br />Areas of 500-year flood; areas subject to the 100-year flood with average depths of less <br />than 1 foot or with contributing drainage area less than 1 square mile; and areas protected <br />by levees from the base flood. <br />Zone C and Zone X (unshaded <br />Areas determined to be outside the 500-year floodplain. <br />(o) "Flood Insurance Study (FIS)" means the official report in which the Federal Emergency <br />Management Agency or the U.S. Department of Housing and Urban Development has provided <br />flood profiles, floodway boundaries (sometimes shown on Flood Boundary and Floodway <br />Maps), and the water surface elevations of the base flood. <br />(p) "Flood Protection Elevation" means the Flood Protection Elevation, or FPE, is the base flood <br />elevation. In azeas where no base flood elevations exist from any authoritative source, the flood <br />protection elevation can be historical flood elevations, or base flood elevations determined <br />and/or approved by the floodplain administrator. <br />(q) "Floodway" means a floodway is the channel of a river or other watercourse and the adjacent <br />land azeas that have been reserved in order to pass the base flood discharge. A floodway is <br />typically determined through a hydraulic and hydrologic engineering analysis such that the <br />cumulative increase in the water surface elevation of the base flood dischazge is no more than a <br />15 <br />
