FLOOD INSURANCE STUDY <br />MONTEZUMA COUNTY, COLORADO, AND INCORPORATED AREAS <br />1.0 INTRODUCTION <br />1.1 Purpose of Study <br />This Flood Insurance Study (FIS) revises and updates previous FISs/Flood <br />Insurance Ra.te Maps (FIRMs) fox the geographic area of Montezuma County, <br />Colorado, including: the City of Cortez, the Towns of Dolores and Mancos; and <br />the unincorporated areas of Montezuma County (hereinafter referred to as <br />Montezuma County). <br />This FIS aids in the administration of the national Flood Insurance Act of 1968 <br />and the Flood Disaster Protection Act of 1973. This study has developed flood <br />risk data for various areas of the ~county that will be used to establish actuarial <br />flood insurance rates. This information will also be used by Montezuma County <br />and the incorporated communities to update existing floodplain regulations as part <br />of the Regulaz Phase of the National Flood Insurance Program (NFIP), and by <br />local and regional planners to further promote sound land use and floodplain <br />development. Minimum floodplairn management requirements for participation in <br />the NFIP are set forth in the Code of Federal regulations at 44 CFR, 60.3. <br />This Countywide Flood Insurance Study was prepared by compiling pertinent <br />information for the flood haz~rd areas in both the incorporated and <br />unincorporated areas of Montezuina County, Colorado, from existing technical <br />and/or scientific data. This existin~ data was reviewed by the Federal Emergency <br />Management Agency (FEMA) prior to its use in the development of this Flood <br />Insurance Study to ensure compliance with NFIP regulations. <br />In some States or communities, flloodplain management criteria or regulations <br />may exist that are more restrictive or comprehensive than the minimum Federal <br />requirements. In such cases, the more restrictive criteria take precedence and the <br />Sta.te (or other jurisdictional agency) will be able to explain them. <br />1.2 Authority and Acknowledgments <br />The sources of authority for this Countywide Flood Insurance Study are the <br />National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of <br />1973. <br />The hydrologic and hydraulic analyses for Chicken Creek and the Mancos River <br />through the Town of Mancos were performed by Muller Engineering Co., Inc., as <br />documented in the report, Flood Plain Information, Mancos River and Chicken <br />Creek, Mancos. Colorado (Mazch 1982). <br />
