<br />structure 1 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 <br />subdivided. <br /> <br />Zone D: <br /> <br />Areas of undetermined, but possible <br />flood hazard. <br /> <br />The flood elevation differences, FHFs, flood insurance zones, and <br />base flood elevations for each flooding source studied in detail <br />in the community are summarized in Table 3. <br /> <br />5.4 Flood Insurance Rate Map Description <br /> <br />The Flood Insurance Rate Map for Glenwood Springs 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 <br />locations of the expected whole-foot water-surface elevation of <br />the base (100-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 />6.0 OTHER STUDIES <br /> <br />In 1977, a study was made of the Colorado and Roaring Fork Rivers at <br />Glenwood Springs, Colorado, for the Colorado Water Conservation Board <br />and the City of Glenwood Springs (Reference 2). The information obtained <br />from that report was used in preparing this Flood Insurance Study. <br /> <br />A study of flow hazard mitigation was made for the Colorado Geological <br />Survey by Arthur I. Mears in 1977 (Reference 10). A study of geologic hazards <br />was made by the Lincoln DeVore Testing Laboratory in 1977 (Reference 11), <br />Information presented in these studies does not conflict with this Flood <br />Insurance Study. <br /> <br />This study is authoritative for the purposes of the NFIP; data presented <br />herein either supersede or are compatible with all previous determinations. <br /> <br />A previous Flood Insurance Study <br />Glenwood Springs (Reference 19). <br />Flood Insurance Study. <br /> <br />was published in 1979 for the City of <br />This study supersedes the previous <br /> <br />25 <br />
