<br />FLOOD INSURANCE STUDY <br />MESA COUNTY, COLORADO (UNINCORPORATED AREAS) <br /> <br />1.0 INTRODUCTION <br /> <br />1.1 Purpose of Study <br /> <br />This Flood Insurance Study revises and updates a previous Flood <br />Insurance Study/Flood Insurance Rate Map for the unincorporated <br />areas of Mesa County, Colorado (Reference 1). This information <br />will be used by Mesa County to update existing floodplain <br />regulations as part of the Regular Phase of the National Flood <br />Insurance Program (NFIP). The information will also be used by <br />local and regional planners to further promote sound land use and <br />floodplain development. <br /> <br />In some states or communi ties, floodplain management eri teria or <br />regulations may exist that are more restrictive or comprehensive <br />than the minimum Federal requirements. In such cases, the more <br />restrictive criteria take precedence and the State (or other <br />jurisdictional agency) will be able to explain them. <br /> <br />1.2 Authority and Acknowledgments <br /> <br />The sources of authori ty <br />National Flood Insurance <br />Protection Act of 1973. <br /> <br />for this <br />Act of <br /> <br />Flood <br />1968 <br /> <br />Insurance <br />and the <br /> <br />Study <br />Flood <br /> <br />are the <br />Disaster <br /> <br />The hydrologic and hydraulic analyses for the original study were <br />performed by the U.S. Army Corps of Engineers (COE), Sacramento <br />District, for the Federal Emergency Management Agency (FEMA), under <br />Interagency Agreement No. lAA-H-16-75 and IAA-H-7-76, Project Order <br />Nos. 21 and 1, respectively.
