<br />FLOOD INSURANCE STUDY
<br />EL PASO COUNTY, COLORADO AND INCORPORATED AREAS
<br />
<br />1.0 INTRODUCTION
<br />
<br />1.1
<br />
<br />Purpose of Study
<br />
<br />.
<br />
<br />This Flood Insurance Study revises and updates information on the existence and severity of
<br />flood hazards in the geographic area of EI Paso County, including the Cities of Colorado
<br />Springs, Fountain, and Manitou Springs, the Towns of Calhan, Green Mountain Falls,
<br />Monument, Palmer Lake, and Ramah, and the unincorporated areas of EI Paso County
<br />(referred to collectively herein as EI Paso County), and aids in the administration of the
<br />National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973, This
<br />study has developed flood risk data for various areas of the community that will be used to
<br />establish actuarial flood insurance rates and to assist the community in its efforts to promote
<br />sound floodplain management. Minimum floodplain management requirements for
<br />participation in the National Flood Insurance Program (NFIP) are set forth in the Code of
<br />Federal Regulations at 44 CFR, 60,3,
<br />
<br />Please note that the Town of Green Mountain Falls is located in EI Paso and Teller Counties,
<br />but is included in its entirety in the EI Paso County Flood Insurance Study,
<br />
<br />In some states or communities, floodplain management criteria or regulations may exist that
<br />are more restrictive or comprehensive than the minimum Federal requirements, In such
<br />cases, the more restrictive criteria take precedence and the State (or other jurisdictional
<br />agency) will be able to explain them,
<br />
