  "text": "(1) Subject to paragraphs (2) and (3), a flood hazard map (or more than one such map taken together) shall show—\n(a) the geographical areas which could be flooded according to the following scenarios—\n(i) floods with a low probability (or extreme event scenarios);\n(ii) floods with a medium probability (likely return period of 100 years or more); and\n(iii) floods with a high probability; and\n(b) the following elements for each of those scenarios—\n(i) the flood extent;\n(ii) water depths or water level, whichever is appropriate; and\n(iii) where appropriate, the flow velocity or the relevant water flow.\n(2) But a flood hazard map need not show information referred to in paragraph (1) as respects a flood with a high probability where the Department considers such a flood would be unlikely to have significant adverse consequences for the area which could be flooded by it.\n(3) The Department may decide that for a coastal area which, in its opinion, is adequately protected from coastal floods, the preparation of a flood hazard map (or more than one such map taken together) may be limited to the scenario referred to in paragraph (1)(a)(i).",
