(2) The flood elevations for these areas correspond to the base-flood elevations specified in the Flood Insurance Study.

(b) Tidal floodplain.

(1) Regulated Flood Hazard Areas in the tidal floodplain are designated on the FIRM as Zones AE, V, VE, and X.

(2) The flood elevations for Zones V and VE are as shown in the Flood Insurance Study's Table 4 {"Transect Data"}, under the column heading "Zone Designation and BFE".

(3) The flood elevations for Shaded Zone X ("areas of 0.2% annual chance flood") and for Zones A and AE are those shown in the Flood Insurance Study's Table 4 {"Transect Data"}, under the column heading "0.2% Annual Chance".

(2) require the applicant to obtain available information from Federal, State, or other sources; or

(3) require the applicant to establish Regulated Flood Hazard Areas and design-flood elevations as set forth in § 2-5 {"Changes to District"} of this subtitle.
