S.L. 549.167 Art. 5Flood hazard maps.

(1) The competent authority shall prepare flood hazard maps and flood risk maps for the areas identified in terms of regulation 4.

(2) Flood hazard maps shall cover the geographical areas which could be flooded according to the following scenarios:

(a) floods with a low probability, or extreme event scenarios;

(b) floods with a medium probability having a likely return period of more than one hundred years;

(c) floods with a high probability, where appropriate.

(3) For each scenario referred to in sub-regulation (2), the following shall be shown:

(a) the flood extent;

(b) water depths or water level, as appropriate;

(c) where appropriate, the flow velocity or the relevant water flow.

(4) Flood risk maps shall show the potential adverse consequences associated with flood scenarios referred to in sub-regulation (2) and shall be expressed in terms of:

(a) the indicative number of inhabitants potentially affected;

(b) type of economic activity of the area potentially affected;

(c) installations as referred to in Annex I of Council Directive 96/61/EC of 24 September 1996 concerning integrated pollution prevention and control which may cause accidental pollution in case of flooding and potentially affected protected areas identified in Annex IV (1)(i), (iii) and (v) to Directive 200/60/EC;

(d) other information which the competent authority considers useful, such as the indication of areas where floods with a high content of transported sediments and debris floods can occur and information on other significant sources of pollution.

(5) For coastal areas and areas where flooding is from groundwater sources the preparation of flood hazard maps shall be limited to floods with a low probability or extreme event scenarios: Provided that for coastal areas the Authority shall establish criteria for determining whether an adequate level of protection is in place.

(6) The flood hazard maps and flood risk maps shall be completed by 22 December 2013.
