5.4 Flood Insurance Rate Map Description

The Flood Insurance Rate Map for Broomfield is, for insurance
purposes, the principal product of the Flood Insurance Study. This
map contains the official delineation of flood insurance zones and
base flood elevations. Base flood elevation lines show the
locations of the expected whole-foot water-surface elevation of the
base (lOO-year) flood. The base flood elevations and zone numbers
are used by insurance agents, in conjunction with structure eleva-
tions and characteristics, to assign actuarial insurance rates to
structures and contents insured under the NFIP.
