<br />elevations of the 10- and 100-year floods is 0.7 foot, the FHF is <br />005; if the difference is 1.4 feet, the FHF is 015; if the difference <br />is 5.0 feet, the FHF is 050. When the difference between the 10- <br />and 100-year flood water-surface elevations is greater than 10.0 <br />feet, it is rounded to the nearest whole foot. <br /> <br />5.3 Flood Insurance ZOnes <br /> <br />Flood insurance zones and zone numbers are assigned based on the <br />type of flood hazard and the FHF, respectively. A unique zone <br />number is associated with each possible FHF, and varies from 1 for <br />a FHF of 005 to a maximum of 30 for a FHF of 200 or greater. <br /> <br />After the determination of reaches and their respective FHFs, the <br />entire incorporated area of the City of Wray was divided into zones, <br />each having a specific flood potential or hazard. Each zone was <br />assigned one of the following flood insurance zone designations: <br /> <br />Zones A7: <br /> <br />Special Flood Hazard Areas inundated by <br />the 100-year flood; with base flood <br />elevations shown, and zones subdivided <br />according to FHFs. <br /> <br />Zone B: <br /> <br />Areas between the Special Flood Hazard <br />Areas and the limits of the 500-year <br />flood; areas that are protected from <br />the 100- or 500-year floods by dike, <br />levee, or other local water-control <br />structure; areas subject to certain <br />types of 100-year shallow flooding where <br />depths are less than 1.0 foot; and areas <br />subject to 100-year flooding from sources <br />with drainage areas less than 1 square <br />mile. Zone B is not subdivided. <br /> <br />Zone C: <br /> <br />Areas of minimal flood hazard; not sub- <br />divided. <br /> <br />5.4 Flood Insurance Rate Map Description <br /> <br />The Flood Insurance Rate Map for Wray is, for insurance purposes, <br />the principal product of the Flood Insurance Study. This map <br />contains the official delineation of flood insurance zoneS and <br />base flood elevations. Base flood elevation lines show the <br />locations of the expected whole-foot water-surface elevation of <br />the base (lOO-year) flood. The base flood elevations and zone <br />numbers are used by insurance agents, in conjunction with structure <br />elevations and characteristics, to assign actuarial insurance rates <br />to structures and contents insured under the NFIP. <br /> <br />15 <br />
