<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 />Zone A: <br /> <br />Special Flood Hazard Areas inundated by <br />the 100-year flood, determined by approx- <br />imate methods; no base flood elevations <br />shown or FHFs determined. <br /> <br />Zones A6-Allr A13r <br />and A15: <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 />leveer 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 Otero County is, for insurance <br />purposes, the principal product of the Flood Insurance Study. This <br />map contains the official delineation of flood insurance zoneS and <br />base flood elevations. Base flood elevation lines show the loca- <br />tions of the expected whole-foot water-surface elevation of the <br />base (lOO-year) flood. The base flood elevations and zone numbers <br />are used by insurance agents, in conjunction with structure eleva- <br />tions and characteristics, to assign actuarial insurance rates to <br />structures and contents insured under the NFIP. <br /> <br />6.0 OTHER STUDIES <br /> <br />A Special Flood Hazard Information report for the Arkansas River and <br />Anderson and King Arroyos was published by the U.S. Army Corps of Engi- <br />neers in 1977 (Reference 1), and a Floodplain Information report for <br />Timpas Creek and the Arkansas River was prepared by MSM Consultants for <br />Otero County and the Colorado Water Conservation Board in 1981 (Refer- <br />ence 2). Data in those two reports were used to prepare this Flood In- <br />surance Study. <br /> <br />18 <br />
