<br />6,0 FLOOD INSURANCE RATE MAP
<br />
<br />The Flood Insurance Rate Map is designed for flood insurance and
<br />floodplain management applications.
<br />
<br />For flood insurance applications, the map designates flood insurance
<br />rate zones as described in Section 5,0 and, in the 100-year floodplains
<br />that were studied by detailed methods, shows selected whole-foot base
<br />flood elevations or average depths. Insurance agents use the zones and
<br />base flood elevations in conjunction with information on structures and
<br />their contents to assign premium rates for flood insurance policies.
<br />
<br />For floodplain management applications, the map shows by tints, screens,
<br />and symbols, the 100- and 500-year floodplains, floodways, and the
<br />locations of selected cross sections used in the hydraulic analyses and
<br />floodway computations.
<br />
<br />7.0 OTHER STUDIES
<br />
<br />Special Flood Hazard Areas in the City of Central City were initially
<br />identified on a Flood Hazard Boundary Map dated August 30, 1974. The
<br />revised Flood Hazard Boundary Map dated April 9, 1976 (Reference 9), was
<br />converted to a Flood Insurance Rate Map on March 1, 1986, Approximate
<br />methods were used to determine the flood hazard at that time. The
<br />Colorado Water Conservation Board performed a detailed hydrology and
<br />hydraulic study as requested by the City of Central City (Reference 5).
