The regulatory floodplain shall be those areas of Calvert County
which are subject to the one-hundred-year flood, delineated on the
most recent revision of the community's Flood Insurance Rate
Maps (FIRM) and described in the Flood Insurance Study (FIS) prepared
by the Federal Emergency Management Agency (FEMA). FIRM maps and the
FIS, if available for the community, must be used. Areas along nontidal
streams that do not have FEMA delineations as described above are
subject to regulation by this chapter and the state.
A community may have one or more of the following Floodplain
Zones:
A. Nontidal floodplains consist of the floodway and the floodway fringe.
Nontidal floodplains may have detailed engineering study data, profiles
and water surface elevations, or may have approximate delineations
only.
B. Tidal floodplains consist of areas subject to coastal or tidal flooding
by the one-hundred-year flood. These areas are flooded due to high
tides, hurricanes, tropical storms and steady on-shore winds.
C. Coastal high-hazard areas consist of areas subject to coastal or
tidal flooding with the addition of high velocity water and wind action.
These areas are designated as V Zones on the Flood Insurance Rate
Maps.
