Zone AE

Zone AE is the flood insurance rate zone that corresponds to the 1 percent annual chance
floodplains that are determined in the FIS report by detailed methods. Whole foot BFEs
derived from the detailed hydraulic analyses are shown at selected intervals within this
zone.

Zone AH

Zone AH is the flood insurance rate zone that corresponds to areas of
1-percent-annual-chance shallow flooding (usually areas of ponding) where average
depths are between 1 and 3 feet. Whole-foot BFEs derived from the detailed hydraulic
analyses are shown at selected intervals within this zone.

Zone X

Zone X is the flood insurance rate zone that corresponds to areas outside the
O.2-percent-annual-chance floodplain, areas within the O.2-percent-annual-chance
floodplain, areas of 1-percent-annual-chance flooding where average depths are less than
1 foot, areas of 1-percent-annual-chance flooding where the contributing drainage area is
less than 1 square mile (sq. mi.), and areas protected from the base flood by levees. No
BFEs or depths are shown within this zone.

6.0 FLOOD INSURANCE RATE MAP

The FIRM is designed for flood insurance and floodplain management applications.

For flood insurance applications, the map designates flood insurance rate zones as
described in Section 5.0 and, in the 1-percent-annual-chance floodplains that were
studied by detailed methods, shows selected whole foot BFEs or average depths.
Insurance agents use zones and BFEs in conjunction with information on structures and
their contents to assign premium rates for flood insurance policies.

For floodplain management applications, the map shows by tints, screens, and symbols,
the 1- and O.2-percent-annual-chance floodplains, floodways, and the locations of
selected cross sections used in the hydraulic analyses and floodway computations.

The countywide FIRM presents flooding information for the entire geographic area of
Clear Creek County. Previously, FIRMs were prepared for each incorporated community
and the unincorporated areas of the County identified as flood-prone. This countywide
FIRM also includes flood-hazard information that was presented separately on Flood
Boundary and Floodway Maps (FBFMs), where applicable. Historical data relating to
the maps prepared for each community are presented in Table 7, "Community Map
History. "
