<br />NOTES TO USERS <br /> <br />This map is for use in administering the National Flood Insurance Program. It does <br />not necessarily identify all areas subject to flooding, particularly from local drainage <br />sources of small size.

Users <br />should be aware that BFEs shown on the FIRM represent rounded whole-foot <br />elevations. These BFEs are intended for flood insurance rating purposes only and <br />should not be used as the sole source of flood elevation information. Accordingly, <br />flood elevation data presented in the FIS Report should be utilized in conjunction with <br />the FIRM for purposes of construction and/or floodplain management. <br /> <br />+ <br /> <br />+ <br /> <br />+ <br /> <br />+ <br /> <br />+ <br />South Fork Elkhorn Creek <br /> <br />1515000 FT <br /> <br />+ <br /> <br />~s: <br />l..Oo;::t <br />"'"''''"' <br />~~ <br /> <br />16 <br /> <br />15 <br /> <br />18 <br /> <br />17 <br /> <br />14 <br /> <br />~~ <br /> <br />ARAPAHO-ROOSEVELT <br />NATIONAL FOREST <br /> <br /> <br />Boundaries of the floodways were computed at cross sections and interpolated <br />between cross sections.

Refer to Section 2.4 "Flood Protection Measures" of the Flood Insurance <br />Study Report for information on flood control structures for this jurisdiction. <br /> <br /> <br /> <br />FEMA recommends that a Flood I nsurance Policy be purchased for structures in <br />areas where levees are shown as providing protection from the 1% annual chance <br />flood. Flooding is not covered by standard propertylfire/dwelling insurance policies nor <br />is it covered by Homeowners Insurance, Renters Insurance, Condominium Owners <br />Insurance, or Commercial Property Insurance.
