, For flood insurance rating purposes, floqd insurance zone designations are assigned to a community based on tlie results of the engineering analyses. These zones are as follows: j. , I i i I 5.0 INSURANCE APPLICATION Zone A Zone A is the flood insurance rate i zone that corresponds to the lOa-year floodplains that are dete~mined in the Flood Insurance Study by approximate methods. Becau~e detailed hydraulic analyses are not performed for such areas, nq base flood elevations (BFEs) or depths are shown wi thin thi s zone.' Zone AE Zone AE is the flood insurance rate; zone that corresponds to the lOa-year floodplains that are dete~mined on the Flood Insurance Study by detailed methods. Whol~-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 500-year floodplain, areas within the 500-year floodplain, areas of lOa-year floo~ing where average depths are less than 1 foot, areas of lOa-year ~looding where the contributing drainage area is less than 1 square ~ile, and areas protected from the lOa-year flood by levees. No BF~s or depths are shown wi thin this zone. 6.0 FLOOD INSURANCE RATE MAP The FIRM is applications. designed for flood insura1ce and , I For flood insurance applications, the m~p designates flood insurance rate zones as described in Section 5.0 an~, in the lOa-year floodplains that were studied by detailed methods, shows selected whole-foot BFEs or average depths.
