The definitions in Chapter 1131 shall apply to this entire section. The following additional definitions shall apply to this section:
(a) Flood Insurance Risk Zones: zone designations on FHBM's and FIRM's that indicate the magnitude of the flood hazard in specific areas of a community. Following are the zone definitions:
(1) Zone A: Special flood hazard areas inundated by the 100-year flood; base flood elevations are not determined.
(2) Zones A1-30 and Zone AE: Special flood hazard areas inundated by the 100-year flood; base flood elevations are determined.
(3) Zone AO: Special flood hazard areas inundated by the 100-year flood; with flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths are determined.
(4) Zone AH: Special flood hazard areas inundated by the 100-year flood; flood depths of 1 to 3 feet (usually areas of ponding); base flood elevations are determined.
(5) Zone A99: Special flood hazard areas inundated by the 100-year flood to be protected from the 100-year flood by a Federal flood protection system under construction; no base flood elevations are determined.
(6) Zone B and Zone X (shaded): Areas of 500-year flood; areas subject to the 100-year flood with average depths of less than 1 foot or with contributing drainage area less than 1 square mile; and areas protected by levees from the base flood.
(7) Zone C and Zone X (unshaded): Areas determined to be outside the 500-year floodplain.
(b) Special Flood Hazard Area (also known as "Areas of Special Flood Hazard"): the land in the floodplain subject to a one percent or greater chance of flooding in any given year. Special flood hazard areas are designated by the Federal Emergency Management Agency on Flood Insurance Rate Maps, Flood Insurance Studies, Flood Boundary and Floodway Maps and Flood Hazard Boundary Maps as Zones A, AE, AH, AO, A1-30, and A99. Special flood hazard areas may also refer to areas that are flood prone and designated from other federal state or local sources of data including, but not limited to, historical flood information reflecting high water marks, previous flood inundation areas, and flood prone soils associated with a watercourse.
